• the seal can be a simple O-ring, which is available very cheaply as a mass part.
• the seal it is also possible and within the scope of the invention for the seal to be flat, for example as a sleeve.
• the jet disc element has an approximately cylindrical extension on its inside, on the front of which the jet disc is attached. This approach can in particular be formed in one piece with the jet disc element.
• the cylindrical extension of the jet disc element interacts with a cylindrical extension of the interior of the housing. It can be provided that the connecting device acts between these two cylindrical projections.
• the seal for the connection element is made in one piece with the seal of the edge of the spray disc, in particular is injection molded.
• the gasket of the jet disc is part of an elastomer disc which bears on the inside of the jet disc and has the jet outlet openings.
• the invention proposes that the seal, which seals the edge of the jet disk from the housing, is subjected to compression in a direction perpendicular to the plane of the jet outlet opening of the housing.
• the spray disc can have spring properties in itself according to the invention. This can be achieved, for example, in that the jet disc has a cross-sectional reduction that runs around its edge.
• the connecting device can, according to the invention, be arranged closer to the connection opening than to the opposite outlet opening.
• connection element has a spherical end section which engages in the housing and which can be pivoted relative to the housing.
• the housing can thus be given away in relation to the connection element attached to one end of the line.
• the seal also enables the fixing of a certain angle at the same time.
• FIG. 1 shows an axial section through a first embodiment of a shower head
• FIG. 2 shows an axial section corresponding to FIG. 1 through a second embodiment of the shower head according to the invention
• FIG. 4 shows an axial section through a fourth embodiment.
• Figure 1 shows an axial section through a shower head according to the invention.
• the shower head contains a housing 1 which has the shape of a cup.
• An opening 3 is formed in the cup base 2, through which a connecting element 4 extends.
• the opposite side of the cup-like housing 1 arranged at the bottom in FIG. 1 forms an opening which is delimited by the peripheral edge 5 of the housing 1.
• the opening is covered by a jet disk 6, which is part of a jet disk element 7.
• a lug 8, which is essentially cylindrical, is formed concentrically on the inside of the jet disk 6 directed into the interior of the housing 1.
• the cylindrical neck 8 engages in another cylindrical neck 9 without play, which is formed in the interior of the housing 1 of the shower head.
• the cylindrical extension 9 assigned to the housing 1 extends from the cup base 2 concentrically to its opening 3 and extends to approximately half the axial extent of the housing 1.
• a wedge-shaped extension that extends at least over part of the circumference Groove 10 formed.
• the cylindrical extension 8 on the inside of the jet disk 6 has a plurality of resilient snap elements 11, which are arranged in a passage opening and distributed over the circumference and have a latching projection on their outside
• the locking projection 12 engages in the circumferential wedge-shaped groove 10 when the jet disc element is inserted into the housing 1.
• a seal 13 is provided, which is designed as an elastomer disc 14 and rests on the inside of the spray disc 6.
• the axial direction is to be understood as the direction between the bottom 2 of the housing and the beam outlet opening on the opposite side.
• the seal 13 designed as an elastomer disc 14 is continued on the inside of the cylindrical extension 8 of the jet disc element 7 up to the free end of the cylindrical extension 8.
• the elastomeric material extends through radially extending openings in the end region of the extension 8 to the outside and seals the housing from the outside.
• a flat seal 15 is thereby formed on the inside of the cylindrical extension 8, on which the end of the connecting element 4 bears flat. This seal 15 is pressed against the end region of the connection element 4 by the cylindrical extension 8 of the jet disc element 7 with the cooperation of the cylindrical extension 9 of the housing 1.
• connection element 4 has a spherical end section 16 arranged in the interior of the housing 1. Braking is achieved by the tensioning of the seal 15 on the outside of the spherical end section 16, so that the housing 1 is locked in a position once it has been assumed. However, the housing 1 can be given away with respect to the end section 16.
• the end section 16 has a passage opening 17 for the passage of the shower water.
• the connection element 4 is designed such that it can be screwed onto a line or a hose.
• the elastomer disk 14 forming the seal 13 is also sprayed through openings in the jet disk 6, the parts sprayed through forming the actual jet outlet openings.
• the shower is assembled as follows. First, the connecting element 4, with its end section pointing upward in FIG. 1, is pushed into the housing 1 from its open side until the spherical end section 16 bears against the edge of the through openings 3. Then the jet disc element is inserted from the open side of the housing 1 until the latching elements 11 snap into the groove 10 with their projections 12. In this state, the seal 13 is compressed in the edge area, so that sealing takes place at this point. Sealing is also carried out at the opposite end by means of the sealing section 15. Tolerances which can occur during the manufacture of the housing and / or the jet disk element 7 are bridged or compensated for by the deformation of the seal 13 in the edge region.
• Figure 2 shows a slightly modified embodiment.
• the connection between the jet disc element 7 and the housing 1 takes place in the same way, namely by means of locking elements 11 which have locking lugs 12 on their outer side in the end region.
• the suspensions can also be molded onto the housing.
• an O-ring 20 is provided, which is held between the cup base 2, the front edge of the cylindrical extension 8 on the inside of the jet disc element and the cylindrical extension 9 on the inside of the housing 1.
• the O-ring 20 is also subjected to a compressive action by the free edge of the cylindrical extension 8, so that in the same way it effects a seal and a braking of the housing 1 with respect to the end section of the connecting element 4.
• the jet disc 26 is sealed off from the edge 5 of the housing by a seal 27 arranged in a radially open groove. Therefore, in this case too, the jet exit disk 26 is in tension in the edge region against the housing 1.
• FIG. 3 shows a further embodiment, in which the jet disk 36 is constructed from a hard part, similar to the embodiment according to FIG. 1, to which an elastomer disk 14 is injection molded.
• This elastomer disk 14 in turn contains parts which are sprayed through openings in the jet disk 36 and which form the jet outlet openings 18.
• the elastomer disc 14 is subjected to compression to compensate for tolerances.
• a sealing lip 31 is injection molded onto the side of the elastomer disk 14 in the interior of the housing 1, which also serves for axial tolerance compensation.
• the axial fixing is done again by locking elements 11 with locking projections 12.
• FIG. 4 shows an embodiment which is similar to the embodiment of Figure 3.
• a bayonet catch is used to connect the housing 1 and the jet outlet disk 36 or the jet disk element, which is effective in the end region of the cylindrical projection 8 of the jet disk element between the latter and the interior of the housing 1.
• this embodiment is constructed similarly to the embodiment according to FIG. 3, so that it will not be described in more detail.
• the installation of the shower head is very simple, since the jet disc element only has to be inserted into the attachment 9 in order to be subsequently rotated in order to close the bayonet catch.
