Description Portable water treatment device, cartridge for water treatment, combination structure of this cartridge and drinking bottle, and water treatment method using this cartridge

TECHNICAL FIELD The present invention relates to a portable water treatment device that can easily purify, adjust, and / or activate water outdoors or on the go. In addition, the present invention provides a portable water treatment cartridge capable of easily purifying, adjusting and / or activating water outdoors or on the go, and a portable water treatment cartridge. The invention also relates to a combination structure with a drinking bottle and a water treatment method using the power bottle. Background art

Most conventional water purifiers are mainly intended for indoor use, and are installed in series or in parallel between a water pipe and a water faucet, and are directly connected to the faucet. There is a 'type' or a pump type that stores tap water etc. in a container to adsorb or evaporate impurities.

As a water purifier that can be carried and used, for example, Japanese Utility Model Registration No. 3117534 discloses a cap for a cartridge-attached bottle bottle. Have been. Then, as shown in Fig. 13, this cap for a bottle contains a porous cartridge 1 カー 2 containing activated carbon 171, etc., inside the cap body 1Ί3. Screw-in It is attached detachably. If the cap 174 is screwed into the mouth 176 of the bottom hole 175 as a cap and fixed, the activated carbon stored in the porous cartridge 172 can be used. Since 17 1 comes into contact with the water inside the pet bottle 17 5, this water can be purified after a certain period of time.

However, as mentioned above, the stationary, tap-connected or pumped-type water purifiers intended for indoor use are not considered for outdoor use at all, and should not be used in mountains, deserts, or unexplored areas. It is completely useless in places where there is no water supply, such as in the area. Therefore, in such a place, if the drinking water brought in is depleted, the water must be used as it is, no matter how polluted the existing water is.

In addition, even if the stationary, faucet-directed or pumped-type water purifiers described above are in a place where water facilities are normally available, the supply of tap water is interrupted due to an earthquake or other disaster. In this case, water must be obtained from nearby rivers and ponds.

In addition, when it is desired to purify water such as tap water when going out (for example, in a hotel), as shown in FIG. 13 disclosed in the above-mentioned Japanese Utility Model Registration No. 3 0 17 5 3 4 A portable water purifier can be used, however, this portable water purifier has a cartridge 1 attached to a cap 17 4 screwed into the mouth 17 6 of a pet bottle 17 5 The activated carbon 17 1 stored in 72 is brought into contact with the water inside the jet bottles 1 to 5 to purify the water. When pouring out the water inside the pet bottle 175 to the outside, the activated carbon 175 was removed from the pet bottle 175 together with the cap 174 to purify the water. Is useless. Therefore, the stationary water inside the pet bottle 175 Water is purified only by contacting activated carbon 17 1 with water, so it takes a considerable amount of time to purify water. For this reason, the purified water in the pet bottle 175 is used up, and if more purified water is needed, the purified water cannot be used immediately. Also, the water inside the pet bottle 175 cannot be so purified. Disclosure of the invention

Further, the annular inner frame portion 42b of the lower filter 42 is fitted to the engaging portion 288 of the hollow fiber case 222. In this case, if necessary, the annular inner frame portion 42b is bonded and fixed to the engaging portion 28. Next, the case body 11 is applied to the case body 11, and then the case body 11 is attached to the case body 12. In this case, the lower end of the case body 11 is fitted and fixed in the annular groove 16 of the case base 12, and the lower end of the case body 11 and the annular outer frame 4 4 of the lower filter 4 2 are fixed. The inner positioning portion 1 2c of the case base 12 is fitted between a and a. Through the above steps, the water purifier main body 2 shown in Figs. 2 and 5 can be easily assembled. When the hollow fiber membrane type filtration mechanism 21 and / or the activated carbon type filtration mechanism 41 in this water purifier main body 2 are clogged, the hollow fiber is filtered after performing the reverse operation of the above-described assembly. New membrane filtration mechanism 21 and / or activated carbon filtration mechanism 41 Replace it with a new one and then reassemble as described above.

If the water purifier body 2 is to be disposable, the lower end of the case body 11 should be attached to the inner positioning part 12 c, outer positioning part 12 d and / or dish base 12 a of the case base 12. It is preferable to adhere in a liquid honey state by sonic welding, adhesive bonding, or the like. Also, if necessary, between the annular outer frame portion 44a of the upper filter 44 and the outer cylindrical portion 11a and between the annular outer frame portion 42a of the lower filter 42 and the inner positioning portion. 1 2c and the outer cylinder 11a may be bonded in the same manner. Further, the annular outer frame portion 44a of the upper filter 44 is previously adhered to the outer cylindrical portion 11a, and the annular outer frame portion 42a of the lower filter 42 is positioned inside the positioning portion 12c. After pre-adhesion, the case body 11, the case base 12, and the filtration mechanisms 21 and 41 may be assembled as described above.

As shown in FIG. 3, the manual water suction pump mechanism 3 includes a water suction pump 51, and a connecting tube 52 on a proximal end integrally connected to a discharge port 51 a of the water suction pump 51. The connection tube 53 on the distal end side integrally connected to the suction port 51b of the water suction pump 51, and the suction nozzle 54 for water intake provided at the distal end of the connection tube 53 on the distal end side. It has. The water suction pump 51 has a discharge port 51a and a suction port 51b formed at both ends of a hollow body 51c having a high elasticity and a restoring force, such as synthetic rubber, respectively. Check the discharge port 51a and the check valve 51a on the suction port 51b (both are not shown) to the discharge port 51a and the suction port 51b. They are provided adjacent to each other in the hollow body 51c.

The proximal and distal connecting tubes 52, 53 are Flexible and elastic. The proximal end of the proximal connecting tube 52 can be detachably fitted into and fixed to the introduction pipe portion 11 c of the water purifier main body 2. The length of the connecting tube 52 on the proximal side is about 15 cm in the illustrated embodiment, but is generally 5 to 30 cm from the viewpoint of ease of use. Preferably there are 10 ~

20 cm is even more preferred. And the distal end connecting tube 5

The length of 3 is also preferably between 15 and 100 cm for the same reason,

More preferably, it is 30 to 70 cm. Note that, instead of the manual water absorption pump mechanism 3, an electric water absorption pump mechanism operated by a battery such as a solar cell can be used.

The suction nozzle 54 for water intake includes a nozzle body 55 fitted and supported by a connection tube 53 on the distal end side, a filter member 56 attached to the nozzle body 55, and a filter member 56 connected to the nozzle body 55. A filter fastening collar 57 is attached to the main body 55. The filter member 56 may be made of a non-woven fabric, a woven fabric, a filter paper, a punching plate made of metal or the like, or a suitable porous material such as a wire mesh. The nozzle body 55 has a substantially cylindrical intake port 55a, such as a substantially cylindrical shape, and a substantially cylindrical support section 55, such as a substantially cylindrical shape, having a smaller diameter than the intake port 55a. b is integrally formed from a suitable material such as a synthetic resin. A fitting groove 58 and a locking groove 59 are formed on the outer peripheral surface of the support portion 55b in this order from the outlet portion 55a side. In addition, the filter member 56 has a cup-shaped central portion 56a that is concavely shaped toward the rear and a substantially cylindrical attachment portion 56b that is substantially cylindrical. A substantially annular connecting sheet portion 56c for connecting the central portion 56a and the attached portion 56b to each other is formed integrally with each other. In addition, the color of the filter fastening 5 7 is a substantially cylindrical hollow body such as a cylindrical body 57a, and a fitting projection protruding from the inner peripheral surface of the hollow body 57a in a substantially annular shape such as an annular shape. The portion 57b is integrally formed from a suitable elastic material such as a synthetic resin.

The process of assembling the above-described intake nozzle for intake 54 and attaching it to the connecting tube 53 on the distal end side may be performed, for example, as follows.

That is, first, the filter fixing collar 57 is inserted into the connecting tube 53 on the distal end side from the distal end side of the tube 53. Next, the distal end portion of the connection tube 53 on the distal end side is fitted into the support portion 55 b of the nozzle body 55 and attached. In this case, if the distal end portion of the connecting tube 53 is locked in the locking groove 59 of the support portion 55b, the support portion 55b is effectively prevented from falling off from the connecting tube 53. You can do it.

Next, the filter member 56 is put on the nozzle body 55 from the tip end side of the nozzle body 55. In this case, the cup-shaped central portion 56a of the filter member 56 is disposed in the substantially cylindrical water intake portion 55a, so that the effective opening area of the filter member 56 is determined by the water intake portion 5. It can be made sufficiently larger than the area of the tip opening of 5a (that is, the cross-sectional area of the tip). Therefore, the water resistance of the filter member 56 ′ is small, and the water to be purified easily passes through. Further, the free end side of the attached portion 56b extends along the support portion 55b of the nozzle body 55 to the vicinity of the locking groove 59. Therefore, if the filter fixing collar 57 is moved to the distal end side of the support portion 55b along the support portion 55b, the fitting projection portion 57b of the collar 57 becomes the support portion 55. Since the fitting portion 58 b of the filter member 56 is press-fitted into the fitting groove 58 of b, the attached portion 56 b of the filter member 56 can be firmly fixed to the supporting portion 55 b. Through the above steps, the intake suction nozzle 54 shown in FIG. 3 and the like can be assembled and attached to the connection tube 53 on the distal end side. If the filter member 56 of the intake suction nozzle 54 is clogged, the process is the reverse of the above-described assembly except for the process of attaching the nozzle body 55 to the connecting tube 53. After performing the operation, the filter member 56 may be replaced with a new one, and then assembled again as described above. In addition, when disposing the intake suction nozzle 54, the filter member 56, the nozzle body 55, and the filter fixing collar 57 are bonded with an adhesive or the like. You may. The water discharge nozzle 4 may be in the form of, for example, an L-shape pipe made of a suitable material such as a synthetic resin. In addition, waterproof rings 61 and 62 are attached to the outer peripheral surface of the base end of the water discharge nozzle 4 as necessary. The base end can be detachably fitted into and fixed to the outlet pipe section 11d of the water purifier main body 2. The protective cover 5, which also serves as a water receiving container, has a cover body 5 a, which may have substantially the same shape (for example, a cylindrical shape) as a normal drinking cup, and protrudes outward at a lower end of the cover body 5 a. The plurality of (for example, a pair) engaged claw portions 5b and 5c formed so as to be integrally formed from a suitable material such as a synthetic resin. Therefore, the protective cover 5 which is also used as a water receiving container is configured so as to be used as a drinking cup. The protective cover 5 prevents the water purifier body 2 when not in use from being contaminated by impurities that enter the case 6 through the inlet pipe section 1 1c and / or the outlet pipe section 1Id. As shown in FIG. 4 and FIG. 5, it is used to cover the water purifier body 2 and is detachably attached to the water purifier body 2. In this case, if the protection cover 5 is put on the water purifier body 2 and then turned clockwise (ie, clockwise), the protection Since the engaged claw portions 5b and 5c of the cover 5 engage with the engaging claw portions 12e and 12f of the case base 12 and abut against the dead end of the case 5, the protective cover 15 It stops at the rotation position and is fixed to the water purifier body 2. When removing the protective cover 5 from the water purifier body 2, the reverse operation to the above-mentioned case of mounting may be performed. When using the portable water purifier 1 shown in Fig. 1 to Fig. 5, first, when the water purifier main body 2 is not used, the water attached to the water purifier body 2 as shown in Figs. Remove the protective cover 5 that also serves as the receiving container as described above.

Then, place the case base 1 2 of the water purifier body 2 on a flat and horizontal place, or hold the entire water purifier body 2 in your hand, and connect the connecting tube 5 on the proximal end side of the water absorption pump mechanism 3. The base end of the water purifier body 2 is fitted and fixed to the inlet pipe section 11c of the water purifier body 2, and the base end of the water discharge nozzle 4 is fitted and fixed to the outlet pipe section 11d of the water purifier body 2. In this case, the watertightness between the outlet pipe 11 d and the base end of the water discharge nozzle 4 is secured by the waterproof rings 61 and 62 attached to the outer peripheral surface of the base end of the water discharge nozzle 4. Can be increased. In addition, since the inlet pipe section 11c and the outlet pipe section 11d protrude upward from the lid plate section 11b of the case 6, the connection on the proximal end side is possible even though the case 6 is compact. The operation of attaching the tube 52 and the water nozzle 4 to the case 6 can be performed easily and reliably.

Next, the water intake suction nozzle 5 4 of the water suction pump mechanism 3 is immersed in the water to be purified. This water may be water contained in a container such as a storage tank, or may be water that is present in a water source such as a river or a pond. Therefore, in this case, the intake nozzle 54 will be directly immersed in the river or pond. Then, pure Place the case base 12 of the water purifier body 2 on a flat horizontal surface such as a table, or hold the entire water purifier body 2 in your hand, and then hold the hollow body 51 c of the water absorption pump mechanism 3 by hand. It is repeatedly deformed by squeezing strongly and compressing, or nearly restored to its original shape by weakly grasping and relaxing. In this case, the water is sucked from the water inlet 55 a of the nozzle body 55 into the support 55 b through the filter member 56 by the water absorbing action of the water suction pump 51. The water sucked into the support portion 55b then flows from the support portion 55b to the connection tube 53 on the distal end side and the check valve on the suction port 51b side as indicated by the arrow in FIG. Through each of them into the hollow body 51c. Further, as shown by arrows in FIGS. 2 and 3, the water sent into the hollow body 51 c passes through the check valve on the discharge port 51 a side and the connecting tube 52 on the base end side. Each of them is introduced into the pre-filtration chamber 46 from the introduction pipe section 11 c of the purifier main body 2. Therefore, the water in the water source can be directly sent into the case 6 of the purifier main body 2 by the water suction pump mechanism 3.

Next, the water introduced into the pre-filtration chamber 46 passes through the activated carbon layer 43 from above to below as shown by the arrow in FIG. 2 and is introduced into the pre-filtration chamber 45 also serving as the post-filtration chamber. You. Therefore, this water is subjected to the purifying action of the activated carbon in the activated carbon layer 43.

Then, as shown by arrows in FIG. 2, the water introduced into the pre-filtration chamber 45 also serving as the post-filtration chamber contains a large number of hollow fibers 23 opening at the lower end face of the potting material layer 29. And moves the potting material layer 29 and the hollow fiber bundle 24 upward from below. At this time, the water gradually permeates from the inner wall to the outer wall of the hollow fiber 23 and is introduced into the post-filtration chamber 30. Therefore, this water is hollow in the hollow fiber bundle 24. The water is also purified by the yarn 23, resulting in very clean water. The purified water introduced into the post-filtration chamber 30 is discharged from the water discharge nozzle 4 to the outside through the outlet 15 as shown by the arrow in FIG. Therefore, if the purified water discharged from the tip of the water discharge nozzle 4 (that is, the water inlet) is received by a container such as the protective cover 5 which also serves as a water receiving container, the purified water can be stored in the container. When the water is received by the protective cover 5 which also serves as a water receiving container, the water in the water receiving container 5 is directly drunk by using the water receiving container 5 as a drinking cup. be able to.

In addition, all the movement of water from the intake port 55 a of the nozzle body 55 until the water is discharged from the outlet nozzle 4 to the outside must be performed by the above-mentioned water absorption function of the water suction pump 51. Can be. In addition, if it becomes unnecessary to further absorb the water to be purified by the water suction pump 51, the water suction nozzle 54 that has been immersed in the water source may be taken out of the water source into the atmosphere. Then, in this state, if the hollow body 51c is squeezed firmly or weakly with the hand continuously, the air in the atmosphere is changed to the pre-filtration chamber 4 of the purifier body 2 as in the case of the water described above. 6 will be introduced continuously. Therefore, the water in the case 6 only partially remains at the bottom of the pre-filtration chamber 45, which also serves as the post-filtration chamber, and most of the water is discharged to the outside through the outlet port 15 and the water discharge nozzle 4 due to the pressure of the air. Released. The water remaining at the bottom of the pre-filtration chamber 45, which is also used as the post-filtration chamber, without being released to the outside even by the pressure of the air, has a very small amount of water having a water line along the lower end surface of the potting material layer 29. It is. Therefore, in particular, the members constituting the water passage (the activated carbon constituting the activated carbon layer 43, the synthetic resin constituting material such as the case 6, etc.) are preliminarily subjected to an antibacterial treatment or the like. Warm up a small amount of residual water It is unlikely that bacteria will propagate in this residual water as a floor. Also, in consideration of this very small amount of residual water leaking out of case 6, there is no particular need to store water purifier body 2 in a liquid-tight bag when not in use. However, if such a small amount of residual water is to be discharged from the inside of the case 6 to the outside, a drain hole is provided in a part of the case 6 such as the dish-shaped base 12 a of the case base 12. In addition, a plug that can removably close the drain hole may be provided.

In the embodiments shown in FIGS. 1 to 5 described above, the case 6 is configured as a whole as a substantially cylindrical shape, but the case 6 may be formed into another cylindrical shape such as a substantially rectangular tube shape or other shapes. It may be hot.

Further, in the embodiment shown in FIGS. 1 to 5 described above, the case 6 is configured as a vertical type, but may be configured as a horizontal type so that the axis of the hollow fiber case 22 is arranged substantially horizontally. .

Further, in the embodiment shown in FIGS. 1 to 5 described above, the introduction pipe section 11 c and the extraction pipe section 11 d are provided on the lid plate section 11 b constituting the upper surface of the case 6. If necessary, it may be provided on the outer cylindrical portion 11a constituting the peripheral side surface of the case 6 or the case base 12 constituting the lower surface. In this case, the configuration of the water treatment means 21 and 41 and the positions of the pre-filtration chamber 46, the pre-filtration chamber 45 and the post-filtration chamber 30 'also serving as the post-filtration chamber can be changed as required.

In the embodiment shown in FIGS. 1 to 5 described above, the inlet pipe section 11 c and the outlet pipe section 1 Id are respectively provided to protrude outward from the case 6. Insert the base end of the connecting tube 52 on the base end side and / or the base end of the water discharge nozzle 4 into the inlet pipe 11c and / or outlet pipe 11d provided so as to extend toward and fix it. The insertion type structure may be used. In the embodiment shown in FIGS. 1 to 5 described above, two types of water treatment means, a hollow fiber membrane type filtration mechanism 21 and an activated carbon type filtration mechanism 41, are used, and the hollow fiber membrane type filtration mechanism 2 is used. 1 was provided in the center of case 6 and activated carbon type filtration mechanism 41 was provided in outer cylindrical space 31 of case 6. However, the material of the filtration material of the filtration mechanism 41 may be other than granular activated carbon such as granular barley stone, granular coral stone, granular functional ceramics, fibrous or granular ion exchange resin, etc. . Instead of the filtration mechanisms 21 and 41, a plurality of types of filtration layers each functioning as a water treatment means may be sequentially stacked from the lower end to the upper end over the entire plane of the case 6. In this case, the material of the filter medium of each filtration layer is selected from a group consisting of granular barley stone, granular coral stone, granular functional ceramics, granular activated carbon, fibrous ion exchange resin, and granular ion exchange resin. One or a plurality of types may be used, and the particle size or fiber diameter of the material of the filtering material may be different from each other in each filtering layer. Then, the moving direction of the water to be treated may be selected to move from below to above, or may be selected to move from above to below. Separators may be provided as necessary at the boundaries between the respective filtration layers. Such separators may be made of non-woven fabric such as felt, woven fabric, filter paper, metal-made punching plate, wire mesh, etc. And any other suitable porous material. Activated carbon and hollow fibers are extremely difficult to remove ionic substances (i.e., basic substances, heavy metals, pesticides, etc.) dissolved in water such as seawater, industrial wastewater, and domestic wastewater. However, if a fibrous or granular ion exchange resin is used as described above, such a substance can be easily removed.

Further, in the embodiment shown in FIGS. 1 to 5 described above, Protective cover 5 is provided, but instead of or in addition to this protective cover 5, when the purifier body 2 is not used, the inlet pipe section 1 1c and / or the outlet pipe section 1 1 A cap member may be provided for closing the opening at the tip of d, and a connecting strip for connecting these cap members to the case 6 may be provided.

Example 2

Next, one embodiment in which the present invention is applied to a water purification cartridge for a water bottle will be described with reference to FIGS.

As shown in Fig. 6, the water purification cartridge 101 is a commonly used beverage cartridge for packing liquid beverages such as drinking water such as natural mineral water for sale. It is used by attaching it to the mouth 103 of Tobotonore 102. This bottom bottle 102 is usually formed in a bottle shape from poly (ethylene terephthalate) (ie, PET). At the time of sales, a well-known cap (not shown) made of metal, synthetic resin, or the like is screwed into the mouth portion 103 of the bottom hole 102, and fixed. The part 103 is kept liquid-tight. As the above-mentioned beverage bottle 102, a liquid beverage that has already been taken out of the market and is empty is used. Then, at the time of water purification, the water to be purified is packed into the empty bottles 102.

The water purifying grid 101 has a case 106 composed of a case body 104 and a case lid 105. The case body 104 is formed in a cup shape, and the upper end thereof is formed thin by forming a step portion 104a on the outer peripheral surface. An appropriate number of openings 107 are formed in the bottom plate 104 b of the case body 104. Further, since a narrowed portion 104 c is formed slightly above the bottom plate portion 104 b, the case body 104 is formed with the narrowed portion 104 c. The lower side has a smaller diameter than the upper side. On the lower surface of the bottom plate 104 b of the case main body 104, a substantially cylindrical engaging portion 104 d whose lower end constitutes a liquid inlet is formed. The inner peripheral surface of the engaging portion 104 d has a male screw portion formed on the outer peripheral surface of the mouth portion 103 of the pet bottle for 1.5 liter. A female screw portion 104e that can be screwed and fixed in a liquid-tight state is formed in 3a. That is, the thread size of the female thread portion 104 e is almost compatible with the thread size of the male thread portion 103 a which is a typical standard dimension. A ring-shaped waterproof gasket 108 made of an elastic material such as rubber is provided at the upper end on the inner side of the inside, so that the female thread 104 e is not so much as the male thread 103 a. Even if it cannot be screwed and fixed in a liquid-tight state, the waterproof packing 108 allows a liquid-tight state between the mouth part 103 and the engaging part 104. The case body 1 In the inside of 04, a porous holding plate 1 11, for example, three types of filtration layers 1 1 2 a, 1 1 2 b, 1 1 2 c constituting the water treatment means, and a porous inner lid plate 1 1 The porous holding plates 111 are locked in a predetermined position by being locked by the narrowed portion 104c of the case body 104. Thus, a pre-filtration chamber 114 is formed between the holding plate 111 and the bottom plate 105b of the case body 104. The filter layers 1 1 2a, 1 1 2b and 1 1 2c are sequentially stacked on top of the filter material of each filter layer 1 1 2a to l 1 2c is granular barley stone. One or more selected from the group consisting of granular coral stone, granular functional ceramics, granular activated carbon, fibrous ion-exchange resin and granular ion-exchange resin. At least one of the filter material, particle size and fiber diameter is It is preferable that they are different. In this case, the particle size or the fiber diameter can be changed without changing the material of the lower filtration layer 112a, the middle filtration layer 112b, and the upper filtration layer 112c.

Separators can be arranged on the boundary between the filtration layers 112a to 112c as necessary. This separator may be made of non-woven fabric such as a filter, woven fabric, filter paper, wire mesh, and other porous materials, similarly to the porous holding plate 111 and the porous inner lid plate 113. .

The case lid 105 has a substantially annular falling portion 105a that is detachably fitted to a thin portion formed by the step portion 104a of the case body 104 and is provided around the outer periphery thereof. Cover plate part 105 b provided. A plurality of openings 115 are formed in the center of the lid plate 105b. On the upper surface of the lid portion 105 b, a substantially cylindrical spout portion 105 c whose upper end constitutes a liquid inlet is formed. Further, a ring-shaped ridge 105d is formed on the outer peripheral surface of the spout 105c. In addition, a ring-shaped engaging portion 116a of the cap member 116 is fitted into the spout 105c. The ring-shaped engaging portion 116a is held in position so as not to fall between the ring-shaped protruding portion 105d and the cover plate portion 105b. Further, a cap portion 116c is connected to the ring-shaped engaging portion 116a via an elongated connecting portion 116b.

Therefore, also in this case, similarly to the cases shown in FIGS. 6 and 7, the water to be purified inside the water bottle 102 can be similarly purified and taken out. The male threaded part of the bottle engaging part 13 The plural types of screw conversion adapters 1 2 3 with different thread dimensions of 1 a are prepared in advance, and the male threaded part of the mouth 10 3 of the bottle 102 is prepared. If these plural types of screw conversion adapters 1 2 1 are selectively used according to the screw dimensions of 103 a, the same water purification power can be used for many types of bottles 102. One can be used. It is of course possible to use the same water purification cartridge 101 for many pet bottles 102 sequentially.

If the filtration layers 11a, 11b, 12c, etc. are contaminated or clogged in the water purification unit 101 shown in Figs. 6 to 8, By removing the lid 105 from the case body 104, it is possible to easily replace the filter layers 112a, 112b, and 112c. When the water purifying unit 101 is to be disposable, the falling part 105 a of the case lid 105 is made thin by the step part 104 a of the case body 104. It is preferable to adhere to the parts in a liquid-tight state by ultrasonic welding or bonding with an adhesive.

Plate 1 1 3, filter material 1 1 2 a to 1 1 2 c, porous holding plate 1 1 1, and penetrating through bottom plate 104 b of case body 104, and case body 1 It extends to the lower part through the engagement portion 104 of 104. Therefore, the lower end of the air inlet tube 126 is further downwardly directed from the engaging portion 104 d of the case body 104 to the outside. It is slightly protruding. At the lower end of the air introduction pipe 126, a check valve 127 for preventing the fluid from moving upward from below is provided as necessary. The check valve 127 can be provided inside the air inlet pipe 126, particularly at the lower part thereof. By reducing the inner diameter of the air inlet tube 126 and increasing the surface tension of the water to be purified inside the water bottle 102, the water leaks out from the air inlet tube 126. If this is not done, the check valve 1 27 can be omitted.

When the water purification cartridge 101 shown in FIGS. 9 and 10 is used in the same manner as the water purification cartridge 101 shown in FIGS. 6 to 8, the lower end of the outside air inlet pipe 1 26 The part is in a state of being inserted into the vicinity of the mouth part 103 inside the bottom part 102. Therefore, when the water inside the pet bottle 102 is poured into the container from the spout 105 c, the water and the same amount of air are injected into the container as indicated by the arrow. The gas is introduced into the pipe 126 from the upper end of the introduction pipe 126, and is introduced into the bottle 102 through the pipe 126 and the check valve 127.

According to the water purification unit 101 shown in FIGS. 9 and 10, the water inside the bottle 102 is poured through the filter media 112a to l12c. The water inside the bottle 102 can be quickly poured into the container because the water easily flows out to the mouth 105c. Since a check valve 127 is provided at the lower end of the air inlet pipe 126, the water inside the bottle 102 flows from the lower end of the air inlet pipe 126 into this pipe 126. There is no risk of flowing into

At the center of the partition plate 13 1 b, a central opening 13 4 is formed to be continuous with the spout 13 1 d, near the outer periphery of the partition plate 13 1 b. A plurality of outer apertures 135 are provided in a ring shape to communicate the side with the upper side. Further, the mounting portion 1311c is formed thin except for the lower end by forming a step 13g on the inner peripheral surface of the lower end. In addition, one half of the tubular spout 13 d is arranged inside the outer cylinder 13 a, and the other half protrudes outward from the outer cylinder 13 a. Further, a ring-shaped ridge 13h is formed on the outer peripheral surface of a portion of the tubular spout 13d that protrudes outward. The configuration between the ridge 13h and the outer cylinder 13a is substantially the same as that of the cap member 16 in the embodiment shown in FIGS. The ring-shaped engaging portion 1 16 a of the cap member 1 16 is held so as not to fall off.

The case lid 13 2 is a substantially annular falling portion 1 3 2 which is detachably fitted to a thin portion formed by the upper step 13 e of the case body 13 1. a is provided with a lid plate portion 132b provided around the outside thereof.

A female screw portion 133d that can be screwed and fixed in a liquid-tight state is formed in 3a. On the lower surface of the bottom portion 133b, a liquid introduction tube portion 133e having a relatively small diameter and a relatively small diameter is further formed. The liquid introduction pipe portion 133 e slightly protrudes further downward from the engagement portion 133 c. In addition, the liquid introduction pipe portion 133 e is substantially concentric with the entire case bottom body 133 and the engagement portion 133 c.

An extension tube 1337, which may be flexible, can be connected to the liquid introduction tube portion 133e as needed. The tube 1337 may have a length that extends to near the lower end of the inside of the pet bottle 102. The liquid inlet tube of the case bottom body 1 3 3 1 3 If 3 e is lengthened, this extension tube 1 37 is unnecessary. However, the height of the bottle 102 varies, so the liquid introduction pipe section 133 e is short so that it can be shared by the bottles 102 of various heights. Better. Further, the liquid introduction pipe section 133 e may be configured so as not to protrude outside, and may have an insertion type structure. Furthermore, a bag-shaped porous filter 13 8 made of synthetic resin or the like can be attached to the lower end of the extension tube 13 7. The porous filter 1338 can remove coarse dirt in water to be purified. By doing so, the surface area of the bag-shaped porous filter 13 8, particularly the effective opening area, is made sufficiently larger than the area of the tip opening of the extension tube 1 38 (that is, the sectional area of the tip). Since the porous filter 1338 has a low water flow resistance, the water to be purified is easy to pass through.

Above the bottom part 133 b of the case bottom body 133, a substantially horizontal air introducing pipe part 133 f is formed extending horizontally. One half of the air introduction pipe section 133 f is arranged inside the case bottom body 133, and the other half projects outside from the case bottom body 133. In addition, a portion protruding to the outside of the gusset introduction pipe portion 133 f is formed with a ring-shaped unevenness for preventing the tube from coming off, thereby constituting a tube connection portion 133 g. An air vent hole 139 is formed near the base end of the tube connection portion 133g. The tube connection portion 133 g may be configured so as not to protrude from the entire case bottom body 133 to the outside, and may have an insertion type structure.

A hollow fiber membrane type filtration mechanism 144 as water treatment means is mounted on the mounting portion 1331c of the case body 1331. The filtering mechanism 144 is formed by bundling a hollow cylindrical fiber case 144 and a large number of hollow fibers 144 in the hollow hollow fiber case 144 arranged inside the hollow fiber case 144. It consists of a thread bundle 1 4 5. Further, a ring-shaped concave groove is formed on the outer peripheral surface near the lower end of the hollow fiber case 144. A 0 ring 147 made of an elastic material is fitted into the concave groove. Further, ring-shaped ridges 144 a and 144 b are formed near the upper end and the lower end of the hollow fiber case 144, respectively. The lower end of the hollow fiber case 14 4 3 is detachably fitted to the mounting portion 13 1 c of the case body 13 1, and the lower end of the hollow fiber case 14 3 is a step 13 of the mounting portion 13 1 c Supported by g. Therefore, a post-filter chamber 148 is formed between the hollow fiber membrane-type filtration mechanism 142 and the partition plate 131b of the case body 131. The lower end of the hollow fiber case 144 and the mounting portion 131c of the case body 131 are almost liquid-tight and elastically in contact with each other via the ring 147. In addition, both ends of many hollow fibers 144 are made of a suitable material such as epoxy resin. The hollow fiber case 144 is solidified by a mounting material 144 and disposed at the lower end of the hollow fiber case 144. The portions other than both ends are bent in a loop shape and extend upward and downward. Further, both ends of the large number of hollow fibers 144 are open to the lower surface of the potting material 144 and connected to the post-filtration chamber 144. A cylindrical space 1 49 between the outer cylinder 1 3 1 a of the case body 1 3 1 and the hollow fiber case 1 4 3 of the hollow fiber membrane type filtration mechanism 1 4 2 has a lower porous sheet. G, a large number of granular activated carbons, and an activated carbon layer 151 as a water treatment means and an upper porous sheet 152 are stacked in order from the bottom to the top. The porous sheets 150 and 152 are made of non-woven fabric such as felt, woven fabric, filter paper, wire mesh, and other appropriate porous materials. It can be formed to have the same shape. These porous sheets 150 and 152 are formed by engaging the lower surfaces thereof with a pair of upper and lower ridges 144 a and 144 b formed in the hollow fiber case 144. Position is held.

The case bottom body 133 is made of a disk-shaped ion exchange resin and is provided with an ion exchange column 153 as water treatment means. A filtration chamber 154 is formed between the ion exchange ram 153 and the bottom plate 133 b of the case bottom 133.

As described above, in the water purification power grid 101 shown in FIGS. 11 and 12, the hollow fiber is located at the center of the case 106, which has a substantially circular vertical shape. A membrane filtration mechanism 14 2 is provided, a second filtration mechanism 15 1 is provided in the outer cylindrical space of the case 10 6, and an ion exchange column 15 3 is provided below the case 10 6. I have. Then, the water to be treated introduced into case 106 is an ion exchange column 15 3. The treatment is performed in this order in the second filtration mechanism 15 1 and the hollow fiber membrane filtration mechanism 14 2. The material of the filter medium of the second filtration mechanism 15 1 is as follows: the filtration layers 11 2 a to l 12 c of the water purification power bridge 101 shown in FIGS. 6 to 8. The one described can be used. In addition, the ion exchange column 15 3 can be omitted as necessary.

When the water purification cartridge 101 shown in Figs. 11 and 12 is used in the same manner as the water purification power cartridge 101 shown in Figs. 6 to 8, manual air The pump 140 should be gripped firmly or weakly by hand. In this way, the air that has passed through the check valve of the pump 140, as shown by the arrow, is connected to the connecting tube 141, the air inlet pipe section 133f of the case bottom body 133, and is opened. It is fed into the inside of the bottom hole 102 through the hole 1336 and the engaging portion 1333c. To this end, the water to be purified inside the bottle 102 is, as shown by the arrows, the porous filter 13 8, the extension pipe 13 7, and the liquid introduction pipe section of the case bottom 13 3. Since it is led to the ion exchange column 15 3 through 13 3 d and the pre-filtration room 15 4, it is purified in the ion exchange column 15 3.

Further, as shown by the arrow, this water is guided to the activated carbon layer 15 1 through the outer opening 13 5 of the case body 13 1 and the porous sheet 150 to be purified. Then, it is guided to the hollow fiber membrane type filtration material 144 through the porous sheet 152 and purified therefrom. In this case, water moves from the outside of each hollow fiber 144 to the inside through the membrane, and flows from one end opening of the hollow fiber 144 to the post-filtration chamber 144. It is derived. Therefore, the impurities in the water adhere to the outer surface of the hollow fiber 144 and are left behind, but the purified water flows from the lower surface of the filter medium 142 to the post-filter chamber 144 as shown by the arrow. 8 and center aperture 1 3 4 Is led to the spout 13 1 d, and is poured into the container from the spout 13 d. The water poured into this container is a porous filter 1

3 8, Ion exchange column 15 3, activated carbon layer 15 1, and hollow fiber membrane type filtration material 1 4 2, are extremely clean.

If this water purification cartridge 101 is used for a long time, the degree of clogging of the water treatment means such as the hollow fiber membrane type filtration mechanism 144, activated carbon layer 151, and ion conversion column 153 will be reduced. As it gets larger, the force required to squeeze the hand-operated air pump 140 in hand increases. If the above clogging progresses further, the end portion 141a of the extension tube 141 rises as shown by the chain line in Fig. 12, so that air leaks from the air vent hole 139. . For this, a manual air pump 1

Since the force for strongly gripping the 40 is suddenly reduced, the user can quickly recognize the clogging.

In the purified water cartridge 101 shown in Fig. 11 and Fig. 12, the hollow fiber membrane type filtration mechanism 144, the activated carbon layer 151, the ion conversion column 1

If the water treatment means such as 53 becomes contaminated or clogged, remove the case lid 13 2 and the case bottom 13 3 from the case body 13 1 respectively to remove the water treatment means. Replacement can be performed easily. When the water purifying cartridge 101 is to be disposable, the falling part 13 2 a of the case lid 13 2 is attached to the case body 13
