Description

Description Universal angle electric mouth cleaning device Technical field

Plaque adhering to the tooth surface and periodontal tissue is a breeding ground for bacteria that cause tooth decay and alveolar pyorrhea, and is a major cause of tooth loss. The present invention relates to a motor-operated oral cleaning tool for preventing caries and periodontal disease. Technology background

In general, the two major diseases of tooth loss are caries and periodontal disease, and electric oral cleaning devices are widely used for oral cleaning to remove and clean plaque, which is the cause. However, these electric oral cleaning devices have a fixed angle between the handle and the brush, similar to general hand-operated toothbrushes. Nothing could be used by freely changing the angle of the neck connecting the brushes. As mentioned above, the usefulness of plaque control is high. However, when cleaning the oral cavity using an electric oral cleaning device, in the environment where the insertion direction is limited, such as the oral cavity, the cleaning brush can easily reach the target site by avoiding the 頰 muscle and tongue muscle. At the same time, the user can reproduce the three-dimensional brush angle suitable for the cleaning position without special knowledge, and the mouth can be automatically cleaned simply by maintaining the cleaning brush that has reached the target part on the spot The purpose is to Another object of the present invention is to provide a motor-operated oral cleaning device that prevents contamination of a cleaning brush and a cleaning tip when carrying the device and improves portability. Disclosure of the invention

The present invention has been made to achieve the above object, and a first invention is to provide a battery holder for accommodating a battery in a main body (body) which is gripped by hand at the time of use for oral cavity cleaning; The motor or the linear motor driven by the motor is built in, and is molded with an elastic synthetic resin or metal so as to pass through a head member detachably mounted in the longitudinal direction of the main body. At one end, the rotational force of the motor and the slide force

(In the case of a motor that generates rotational force, it is converted by a crank force mechanism.) Alternatively, a rotary shaft, a slider shaft, or a rotary slider shaft having a joint mechanism for joining to a connecting part that transmits rotary slide kinetic force. A variety of cleaning parts are mounted on the rotating shaft, slider shaft, or the other end of the rotating slider shaft, and the rotating shaft, slider shaft, or rotating of an electric oral cleaning tool that cleans the mouth by driving the mouth cleaning unit with the power of a motor. Slider An electric oral cleaning tool provided with a head part that passes through one shaft. The head part is made of a soft resin, etc., and has the property of being permanently deformed so that it passes through the core as a core. The shape of the head member that connects the main body and the cleaning brush is three-dimensionally changed by finger pressure by insert molding of the annealed metal wire etc. By maintaining and deforming freely into a shape that matches the cleaning target site, when cleaning the mouth using an electric oral cleaning tool, it is possible to easily remove the tongue and tongue muscles, etc. To reach the cleaning brush.

Cases with swelling due to gingival inflammation and molars that cannot be seen directly with this electric oral cleaning device, especially the distal part of the last molar and interdental region. Even if there is a restriction on the insertion direction of the plaque control, the plaque control can be performed simply by holding the cleaning brush from the arbitrary It is possible to clean the tooth surface accurately and to prevent damage to the interdental papillary gums, and it will not apply unnecessary pressure to the cleaning brush or cleaning tip itself or the joint between the mouth cleaning part and the body. Damage can be prevented and durability can be improved.

Furthermore, as in the past, when the cleaning section of the main body had a fixed angle in advance so that the cleaning section, such as a cleaning brush or a cleaning tip, could reach the target portion, the storage case would have the same angle. The head part is made of soft resin, so it is bulky because it is kept, but the neck part connecting the main body and the cleaning part can be changed or restored three-dimensionally freely by finger pressure. After the mouth cleaning operation, the head is used before the use by using an electric mouth cleaning tool equipped with a neck formed by insert-molding an annealed metal wire etc. that has the property of being permanently deformed as a core material inside it. Since it is possible to restore and deform to a linear shape that fits the storage case by finger pressure, it is possible to store cleaning parts such as cleaning brushes and cleaning tips in a compact form to improve portability. Can.

The second aspect of the present invention provides a rotary sliding motion of the slider shaft according to the first aspect of the present invention in order to automatically perform oral cleaning only by maintaining a cleaning portion such as a cleaning brush or a cleaning tip at a target portion. And an L-shaped or T-shaped bend or protrusion shaped so that one end is attached to the rotating slide shaft of the joint mechanism and the other end transmits the motor's one-turn force. And a push port that is movably installed from the main body to the inner surface and that always has the protruding portion retracted by the coil spring. When pressed by finger pressure, the convex portion comes into contact with the joint mechanism and slides on the joint mechanism. The cylindrical cam is mounted on the shaft, and the cylindrical cam is always pushed in the motor direction. And a coil coil mounted between the body body shaft mounting part and the cylindrical cam. L-shape or T-shape, in which the shaft can move freely only in the long axis direction, in order to apply a rotating motion so as not to hinder the sliding motion of the shaft while being attached to the pulling and motor rotation shaft. When the movable protruding part is brought into contact with the cylindrical cam by the electric oral cleaning tool consisting of a part of the slide connector with a groove in the long axis direction that fits into the shaft-like projection Since the cleaning brush rotates by the rotational force of the motor or when the movable projection is separated from the cylindrical cam, the cleaning brush rotates. The neck of the cleaning part is three-dimensionally bent by finger pressure and inserted into the interdental area and maintained in place.Efficient automatically without manual cleaning in the crown and tongue direction Ku it is possible to oral hygiene.

The third invention is a flexible resin capable of deforming the neck of the electric oral cleaning tool by finger pressure in order to improve portability and prevent contamination of a cleaning portion such as a cleaning brush or a cleaning tip when carrying. By performing an insert molding process using an annealed metal wire or the like, which has the property of being permanently deformed, inside the head member molded by using a core material, the neck part that is bent three-dimensionally according to the intended use is straightened. In addition, the portability can be improved by restoring and deforming to fit the shape of the storage case. In addition, a hinge mechanism is provided at the joint between the main body (body) and the head member, so that the overall shape can be stored like a folding knife, and the shape of the neck of the electric oral cleaning tool matches the shape of the storage space The head can be freely deformed and the cleaning part such as the cleaning brush and the cleaning tip can be stored in the main body, so that not only the portability is further improved but also the cleaning brush part. Pollution can be prevented.

The fourth invention is a modification of the first invention, and is a rotating shaft, a slider shaft or a rotating slider formed of synthetic resin or metal having elasticity. The head member detachably mounted in the longitudinal direction of the main body passing through the shaft is constituted by a bearing part having a plurality of linearly continuous shaft through holes, and the plurality of bearing parts are formed by the slider shaft. By connecting two parallel annealed metal wires with permanent deformable physical properties or a cylindrical member molded from a material such as metal with permanent deformable properties through a slider shaft. The permanent deformable member portion, which is a joint portion, can be freely bent and deformed by finger pressure. Further, the bending direction of the cleaning brush with respect to the main body can be defined three-dimensionally by displacing the bending position of the annealed metal wire arranged in parallel back and forth with respect to one axis of the slider. .

However, in the case of the above-described head portion formed of an annealed metal wire having physical properties that can be permanently deformed in parallel with the slider axis, the bending direction of the joint portion is constant. Therefore, by combining the bendable directions of a plurality of parallel joints, it is possible to easily form the head into a standard and ideal three-dimensional shape even for hard-to-reach parts such as the adjacent surface of the molar teeth. Can be transformed.

This means that even if the joint is formed of a cylindrical material molded from a material such as metal that has the property of permanently deforming the joint, the foldable direction of the cylindrical material itself is adjusted by adjusting the cross-sectional thickness of the cylindrical material and the material. Can be deformed into a standard and ideal three-dimensional shape by defining it in a certain direction, so it can be cleaned with various cleaning brushes, synthetic resin, etc. using 頰 muscles ゃ tongue muscles, tooth clumps, etc. Parts that are hard to reach the tip can be easily cleaned, and when stored, the head part can be easily restored to linear shape by finger pressure and stored in a compact storage case, making it easier to carry. Can be improved. According to a fifth aspect of the present invention, the plaque on the interdental portion and the occlusal surface can be removed without moving the main body by merely positioning the cleaning brush of the electric oral cleaning tool at the cleaning target site. By brushing the brush portion in a spiral manner, the cleaning brush of the electric oral cleaning device that performs the rotary sliding motion according to the second aspect of the present invention is intentionally used for plaque using the rotational force. Is a cleaning brush that can discharge the ink in a certain direction on the 頰 or lingual side.

The sixth invention, like the fifth invention, has the ability to remove the plaque at the interdental portion and the occlusal surface without moving the main body only by positioning the cleaning brush of the electric oral cleaning device at the cleaning target site. In order to further increase the cleaning brush part spiral arrangement in the fifth invention, the bristle tip implanted in the brush part of the electric oral cleaning tool is moved forward or backward with respect to the cleaning brush rotation axis direction. This cleaning brush can be curved (curled) to further increase the efficiency of squeezing out the plaque due to the rotational force of the brush. The seventh invention is directed to the rotary sliding motion according to the second invention in order to further enhance the ability to extract plaque at the interdental portion and the occlusal surface as in the fifth invention and the sixth invention. The brushing direction of the brush of the electric oral cleaning tool is set in the forward or reverse direction with respect to the direction of rotation of the cleaning brush, or at an angle in the direction of the tip or main body with respect to the direction of the longitudinal axis of the cleaning brush. By arranging them, it is possible to increase the plaque cleaning ability of pit fissures and interdental areas, and to provide an electric oral cleaning tool equipped with a cleaning brush that intentionally discharges teeth 頰 or lingually.

According to an eighth aspect of the present invention, the linear portion of the slider composed of a straight portion formed of a synthetic resin or a metal, which is passed through the head portion and a bent portion, and the linear portion of the slider and the head end bearing portion having rigidity are formed. The material or shape is used, and the bent portion connecting the straight portions is made of a material that is more elastic than the straight portion, or if the same material is used, the bent portion is compared with the straight portion. By making the cross-sectional area smaller and exhibiting a more elastic shape, the slider can smoothly perform the sliding motion and the rotating motion. Therefore, even if the bending angle of the head portion forming the outer shell is set to an angle equal to or greater than a right angle, it is possible to minimize the loss of the driving force of the motor. Furthermore, when this mechanism is used to configure a combination of a bent shape and a linear shape, the bending radius of the bent shape can be reduced to 5 millimeters or less, so the head ( By reducing the length of the straight portion and the first bent portion in the immediate vicinity of the cleaning brush), it is possible to shorten the major axis in the direction of the long axis of the rear end of the cleaning brush. Never. If the slider is made of the same shape or material, the slider protruding from the bearing at the head end and the cleaning brush attached to the end of the slider will rotate or slide. The internal stress of the brush causes the brush tip to vibrate in a direction other than the axial direction, which hinders the insertion of the brush into a narrow gap like an interdental brush. The resonance of the cleaning brush can be prevented by using a rigid material or shape for the slider of the end bearing and by precisely inscribed in the head end bearing.

In the ninth invention, a freely rotating spherical or disk-shaped bead-shaped bearing is inserted through a slider shaft at arbitrary positions in contact with the inner wall of the head member, or the shape of the slider shaft itself is changed to an arbitrary value. By molding the ball into a spherical or disk-like shape at several locations, it is possible to reduce the contact area between the inner wall of the head and the slider, thereby reducing heat generation due to friction, noise and driving force. Prevented electric mouth cleaning tool.

A tenth aspect of the present invention is to connect the end to the slider shaft at the same position as the rotation center axis, and to transmit the rotational force of the motor shaft to the other end in order to generate rotational sliding motion on the slider shaft. A cylindrical shape with a polygonal hole, a ring shape with the same starting point and ending point on the outer periphery of the cylindrical surface in the longitudinal direction A cylindrical cam with a groove that smoothly displaces in the long axis direction (rotation axis direction) is installed. The cylindrical cam groove fits into the inner wall of the head member through which this cylindrical cam passes. This mechanism makes it possible to freely change the number of slide movements and the stroke each time the cylindrical cam makes one rotation according to the shape of the groove of the cylindrical cam. Appliances.

The invention of the H-th aspect is characterized in that the movement of the crankshaft connected to the motor of the main body is connected to the other end of the cylindrical cam having one end joined to the slider axis and having the same rotation center axis as the tenth invention. A cylindrical mechanism having a groove that smoothly displaces in the long axis direction (repeated rotational movement axis direction) provided with a cam mechanism for converting to the repetitive rotational movement of the slider shaft, wherein the cylindrical cam passes through The mechanism by which the groove of the cylindrical cam fits into the cam notch on the inner wall of the head member makes it possible to freely vary the number of slide movements and the stroke amount that occur each time the slider shaft rotates repeatedly. A motor-operated oral cleaning device characterized by the following.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show an example of an embodiment of the invention. In the drawings, the portions denoted by the same reference numerals as those in the drawings represent the same components, and the basic configuration is the same as that shown in the drawings. However, as shown in FIG. 1, the power of the motor 9 is controlled by the spur gear 8 and the face gear 6 fixed by the gear bearing 12 of the main body 3 as shown in FIG. To rotate. This rotational power is transmitted to the eccentric cam 7 by the gear shaft 11 and converted into a sliding motion parallel to the long axis direction of the main body by the crank wheel 5 fitted outside the eccentric cam 7 guided by the main body 3. You. The sliding motion of the crank wheel 5 is propagated to the slider 4 which passes through the head member 2 and causes the cleaning brush 1 having an insert formed at the tip to slide. At this time, the direction of the sliding motion parallel to the main body 3 of the crank wheel 5 is set by the two-dimensional or three-dimensional bending shape of the head member 2 through which the elastic slider 4 passes. Is done. When the cleaning brush 1 is inserted into the interdental portion by gripping the main body 3 of the electric oral cleaning device of the above-described example, the cleaning brush 1 slides by the driving force of the motor 9, and is manually moved in the tongue direction. The interdental plaque is automatically cleaned while standing still without fine movement.

Also, as shown in FIG. 2, the head portion is formed by an annealed metal wire 17 having permanent deformable physical properties, which is insert-molded so as to pass through a head member 2 molded of a soft resin or the like. As shown in FIG. 3, FIG. 4, and FIG. 5, the cleaning brush 1 can be freely three-dimensionally deformed by acupressure, so that the cleaning brush 1 can reach a target portion while avoiding frequent tongues. Furthermore, after using the mouth cleaning, the head member 2 conforms to the shape of the storage case 19 as shown in FIG. It is possible to store it after restoring the deformation by finger pressure.

As shown in Fig. 8, Fig. 9, Fig. 10, the storage method is to provide a butterfly plate 25 at the connection between the main body 3 and the head member 2, as shown in Fig. 8, Fig. 9, and Fig. 10. By folding and storing it, it is possible to shorten the overall length of the electric oral cleaning device when not in use (when carrying it), and in use, as shown in Fig. 9, from the brush protector 22 to the head 2 Then, the cleaning brush 1 is pulled out, and the head member 2 can be automatically deformed by finger pressure according to the intended use and used as shown in FIG.

In addition, the power of the motor 9 is not changed even in the rotating oral moving appliance shown in FIG. 7 in which the movement of the cleaning brush 1 is different from the sliding operation such as the electric oral cleaning device shown in FIG. The face gear 6 fixed by the gear bearing of the main body 3 by the spur gear 8 is rotated. This rotational power is transmitted to the brush rotary shaft spur gear 27, rotates the slider 4 attached to the slider joint 23 guided by the main body 3, and drives the cleaning brush 1 through the slider 4. Similarly, in the rotating configuration, the head member 2 can be three-dimensionally deformed by finger pressure using the annealed metal wire 17 having insert-molded and permanently deformable physical properties. The cleaning brush 1 to be cleaned can easily reach the cleaning target portion. As shown in FIG. 11, similarly, in the electric-powered oral-cleaning device of the mechanism that performs a further advanced sliding motion, the cleaning brush 1 can easily reach the target portion. In this mechanism, the rotating power generated by the motor 9 rotates the slide cam shaft 35 by the slide shaft joint 32 and also rotates the cylindrical cam 30 mounted on the slide cam shaft 35. When the protruding part of the push port pad 31 that is separated from the cylindrical cam 30 by the push rod coil spring 33 is pushed in with finger pressure, the camshaft coil spring is always 2 9 _c the rotary slide motion to generate a slide motion in contact with the cylindrical cam 3 0 which is pressed against the motor-9 side in addition to the rotational motion to the scan line Dokamushafu bets 3 5 by the brush rotation shaft joint The cleaning brush 1 is caused to perform a rotary sliding motion by propagating the cleaning brush 1 to the brush rotary slide shaft 34 by 2 8. The cleaning brush 1 which makes this rotary sliding motion can three-dimensionally deform the head member 2 formed by insert-molding the annealed metal wire 17 having the property of being permanently deformed. Just hold it on the site and automatically extract and scrub the plaque without manually moving the cleaning brush in the tongue direction.

All of the above electric oral cleaning tools are shown in Fig. 1, Fig. 2, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 11, Fig. 22, Fig. 23, As shown in FIG. 24, FIG. 27, FIG. 28, and FIG. 29, the head member 2 including the cleaning brush 1 and the slider 4 rotates the main body 3 and the slider joint section 23 or When the cleaning brush 1 is worn out or becomes contaminated by repeated use, the head member 2 is removed and the parts are replaced. Lee 10) is to be used continuously.

Further, the cleaning brush portion 1 of the electric oral cleaning device performing the rotary sliding motion is provided with a cleaning brush portion radially planted from the brush shaft as shown in FIG. The cleaning brush, which is arranged in a spiral, automatically pulls out plaque in a certain direction by the rotational movement. Alternatively, as shown in Fig. 13 and Fig. 14, the long axis of the bristle that is implanted radially from the brush shaft is in the direction of rotation of the cleaning brush part or in the direction of the tip with respect to the long axis of the cleaning brush rotation shaft. , Or a cleaning brush in which the brushes are arranged at an angle so that they have a positive or negative angle in the rear end direction, or a brush that is implanted in a cleaning brush part that rotates and slides as shown in Fig. 15 Tip The cleaning brush, which is curved (curled) in the forward or reverse direction to the direction of rotation of the cleaning brush, has a high cleaning ability even for pit fissures and interplaque plaque. The shapes of the cleaning brushes shown in FIGS. 12 to 15 alone enhance the cleaning ability alone, but when combined, the ability is further exerted.

Also, as shown in Fig. 16 to Fig. 18, as the bending mechanism of the head part, when using two annealed metal wires having the property of permanent deformation, the shape of the head part can be changed by finger pressure. It is possible to bend at an arbitrary angle in a certain direction as shown in Fig. 19, but as shown in Fig. 30, the arrangement of the bending positions of the two annealed metal wires having the property of permanent deformation as shown in Fig. 30 By changing the angle, the bending direction can also be specified. As shown in FIGS. 20 and 21, the same bending mechanism is used at an angle rotated 90 degrees with respect to the long axis direction. By using a configuration in which the heads are arranged, it is possible to deform the head into a more complex three-dimensional shape by finger pressure, so coloring is also possible on areas that cannot be reached directly, such as the intermolar portions of the molars. By manually documenting the bending angle and order of each bent part It is possible public is deformed preferred shape with readily reproducible. It goes without saying that this mechanism that bends only in a certain direction helps to easily return to a straight state, as well as during storage.

In addition, FIGS. 22 to 29 show practical embodiments. As shown in FIG. 24, two annealed metal wires 17 having permanent deformable properties are insert-molded at the tip of a head portion 2 molded of a detachable soft resin, and the head portion is formed. At the center of 2, it is held by a head bearing 13 and a cleaning brush 1 is attached at one end and a cylindrical cam 30 is provided at the other end, and bearings are provided at several positions in contact with the inner wall of the head. Slider 4 with 4 2 passes through the shaft. The cylindrical cam 30 is, as shown in FIGS. 25 and 26, It has a polygonal hole for receiving the slide shaft 41 for transmitting the rotational force of the motor shaft inside, and a ring-shaped long axis direction with the same starting point and end point on the outer surface in the long axis direction. It has a cam groove 4 4 that moves smoothly. Since the cam groove 44 fits into the cam notch 43 on the inner side wall of the head 2, one reciprocating motion (sliding motion) is generated each time the motor makes one rotation. This rotating slide motion is not only minimized in the driving force even when the head part 2 is bent sharply by the bearing part 42 as shown in FIG. Prevent heat and noise. In addition, the slider bent portion 4a has a shape that exhibits flexible elasticity, while the slider straight portion 4b has a rigid shape and is precisely held by the head bearing portion 13. This prevents the cleaning brush 1 from vibrating in a direction other than the axial direction when the cleaning brush 1 rotates. As another embodiment, as shown in FIGS. 27 and 28, a crank bearing portion 46 having a groove in a direction perpendicular to the axial direction is provided with a crankshaft 45 for transmitting the driving force of the motor 9. The rotary motion of the cylindrical cam 30 is converted into the repetitive rotary motion of the cylindrical cam 30. Further, the cam groove 44 cut into the cylindrical cam 30 is moved by the cam notch 43 of the head member 2 to the cleaning brush 1 via the slider 4. A repetitive rotating slide motion is generated at the same time. Alternatively, when using a linear motor 24, as shown in FIG. 29, a cam groove 4 cut into a cylindrical cam 30 in which a linear motor crank shaft 47 is axially rotatably mounted. The slide motor 4 converts the slide motion of the linear motor 124 into a repetitive rotation slide motion through the cam notch 43 of the head member 2 and transmits the slide motion to the cleaning brush 1 via the slider 4.

In addition, the entire shape of the present invention, the shaft material, the material of the annealed metal wire having the property of permanent deformation, the shape of the cleaning brush for cleaning purpose, the sliding motion, the rotating motion, or the rotating sliding motion of the cleaning brush. mechanism, In addition, the use of the rear motor mechanism in the power system of the rotary motor 9 is not limited to the above illustrated example, and various changes can be made without departing from the scope of the present invention. .
