A membrane 68 provided with a central orifice is subjected to the action of a spring 69 and to the pressure of the water penetrating through the channel 82 when the movable plate 73 is in the low position, so that the water mixture - soap is carried out in the chamber 83 and is evacuated through the chamber 77 through the orifices 78 of the cap 75 movable in rotation and in translation relative to the body 61.

Description

La présente invention concerne un dispositif mélangeur automatique pour ajouter des produits cosmétiques liquides à l'eau, comportant un conduit d'amenée d'eau sous pression, une chambre pour contenir une quantité déterminée de produits cosmétiques liquides, et au moins un conduit de sortie pour l'eau additionnée de ces produits.The present invention relates to an automatic mixer device for adding liquid cosmetic products to water, comprising a pressure water supply duct, a chamber for containing a determined quantity of liquid cosmetic products, and at least one outlet duct for the water added with these products.

Les systèmes mélangeurs connus sont du type GIFAR. Ces systèmes comportent une tubulure principale, dans laquelle circulent l'eau et un conduit annexe raccordé à la tubulure principale et à un réservoir de produits cosmétiques liquides, par exemple de savon liquide. Un déflecteur, ménagé dans la tubulure principale, engendre une dépression au niveau du raccordement du conduit annexe, ce qui permet d'aspirer une certaine quantité de savon liquide, qui se mélange à l'eau de la tubulure principale.Known mixing systems are of the GIFAR type. These systems include a main tubing, in which the water circulates, and an annex duct connected to the main tubing and to a reservoir of liquid cosmetic products, for example liquid soap. A deflector, formed in the main pipe, generates a vacuum at the connection of the annex pipe, which allows to suck a certain amount of liquid soap, which mixes with the water of the main pipe.

Ce dispositif bien connu présente un certain nombre d'inconvénients. En particulier, il ne comporte aucun organe de fermeture assurant l'étanchéité au niveau du réservoir de savon, de sorte que le savon liquide peut, dans certains cas, remonter dans la conduite d'eau courante, après la fermeture du robinet. En outre, le débit de savon fait fonction de plusieurs paramètres tels que le débit de l'eau dans la tubulure principale, la pression de l'eau dans la conduite, etc, ce qui rend le débit de savon pratiquement incontrôlable et nécessite une adaptation de chaque appareil au moment de son installation, en fonction des conditions locales. Enfin, on a constaté qu'avec ces dispositifs, on utilise une très grande quantité d'eau pour une quantité très faible de savon liquide.This well known device has a number of drawbacks. In particular, it does not have any closing member ensuring sealing at the level of the soap tank, so that the liquid soap can, in certain cases, rise in the running water pipe, after the tap is closed. In addition, the flow of soap depends on several parameters such as the flow of water in the main tubing, the pressure of the water in the pipe, etc., which makes the flow of soap practically uncontrollable and requires adaptation. of each device at the time of installation, depending on local conditions. Finally, it has been found that with these devices, a very large amount of water is used for a very small amount of liquid soap.

La présente invention se propose de remédier à cet inconvénient, en réalisant un dispositif mélangeur dans lequel le réservoir à savon liquide est bien isolé par rapport au conduit d'eau sous pression, de telle manière que le savon ne puisse s'écouler de ce réservoir qu'au moment où l'eau circule à travers le dispositif.The present invention proposes to remedy this drawback by providing a mixing device in which the liquid soap tank is well insulated from the pressurized water pipe, so that the soap cannot flow from this tank. as the water flows through the device.

Dans ce but, le dispositif mélangeur selon l'invention est caractérisé en ce qu'il comporte au moins un circuit intérieur reliant le conduit d'amenée au conduit de sortie, une membrane rigide sensiblement plane dont la face intérieure est en contact avec l'intérieur de la chambre contenant les produits cosmétiques et dont la face extérieure est en contact avec ledit circuit intérieur, ladite membrane comportant un bossage central percé d'une ouverture permettant d'amener la chambre en communication avec ledit circuit intérieur, et un organe ressort agencé pour appliquer le bossage contre une paroi du circuit intérieur de telle manière que l'ouverture de communication avec la chambre contenant les produits cosmétiques soit fermée lorsque le dispositif n'est pas alimenté en eau sous pression.For this purpose, the mixing device according to the invention is characterized in that it comprises at least one internal circuit connecting the supply duct to the outlet duct, a substantially flat rigid membrane the inner face of which is in contact with the interior of the chamber containing the cosmetic products and the outer face of which is in contact with the said internal circuit, the said membrane comprising a central boss pierced with an opening enabling the chamber to be brought into communication with said internal circuit, and a spring member arranged to apply the boss against a wall of the internal circuit in such a way that the opening for communication with the chamber containing the cosmetic products is closed when the device is not supplied with pressurized water .

  • La figure 1 représente une première forme de réalisation du dispositif mélangeur automatique selon l'invention, adapté sur une pomme de douche,
  • Les figures 2A, 2B et 2C illustrent schématiquement le fonctionnement du dispositif mélangeur monté sur la pomme de douche de la fig. 1,

The present invention will be better understood with reference to the description of an exemplary embodiment and the attached drawing, in which:
  • FIG. 1 represents a first embodiment of the automatic mixer device according to the invention, adapted on a shower head,
  • FIGS. 2A, 2B and 2C schematically illustrate the operation of the mixer device mounted on the shower head of FIG. 1,
  • FIG. 3A represents another embodiment of a shower head equipped with an automatic mixer device according to the invention, this device being shown in its rest position,
  • FIG. 3B represents a view similar to that of FIG. 3A with the automatic mixing device in the working position, and
  • Figure 4 shows a sectional view of another embodiment of a mixing device according to the invention.

En référence à la fig. 1, le dispositif mélangeur automatique est monté dans une pomme de douche comportant un corps 1 pourvu, au centre de sa base, d'une plaquette 2 traversée par une multitude de canaux 3. Autour de la plaque de base 2, -le corps de la pomme de douche 1 comporte une plaque annulaire 4, également traversée par une série de canaux 5 de forme conique et disposés par exemple en deux rangées concentriques. A titre facultatif, cette pomme de douche est équipée d'une brosse 6 pourvue d'une série de dents 7, par exemple en caoutchouc, et traversée par des canaux 8 disposés dans le prolongement des canaux 5 de la plaque annulaire 4.With reference to fig. 1, the automatic mixer device is mounted in a shower head comprising a body 1 provided, at the center of its base, with a plate 2 crossed by a multitude of channels 3. Around the base plate 2, the body of the shower head 1 comprises an annular plate 4, also crossed by a series of channels 5 of conical shape and arranged for example in two concentric rows. Optionally, this shower head is equipped with a brush 6 provided with a series of teeth 7, for example made of rubber, and traversed by channels 8 arranged in the extension of the channels 5 of the annu plate. area 4.

Le corps de la pomme de douche 1 comporte un évidement central, qui constitue une chambre 9 destinée à contenir les produits cosmétiques, par exemple le savon liquide. La chambre 9 est fermée hermétiquement par un bouchon 10 vissé sur le corps 1. Le bouchon 10 pourrait être remplacé par un réservoir vissé sur le corps de la pomme de douche et contenant une réserve de produits cosmétiques.The body of the shower head 1 has a central recess, which constitutes a chamber 9 intended to contain cosmetic products, for example liquid soap. The chamber 9 is hermetically closed by a plug 10 screwed onto the body 1. The plug 10 could be replaced by a reservoir screwed onto the body of the shower head and containing a reserve of cosmetic products.

A l'intérieur de la chambre 9 se trouve une membrane 11 de forme circulaire, et dont le diamètre est de préférence très légèrement inférieur au diamètre de la chambre 9 de forme cylindrique, de telle façon que cette membrane puisse se déplacer avec un faible frottement à l'intérieur de la chambre. La surface supérieure de la membrane 11 est sensiblement plane. La surface inférieure présente un bossage central 12, dont la zone centrale plane 13 est entourée d'une zone annulaire 14 qui se trouve à un niveau différent de celui de la zone centrale 13, ces deux niveaux étant raccordés par une surface inclinée 15. En d'autres termes, le bossage central 12 a une forme sensiblement tronconique, et l'épaisseur de la membrane 11 est supérieure, au niveau de la zone centrale 13, à celle mesurée au niveau de la zone périphérique 14. Des joints d'étanchéité 16 et 17 assurent l'étanchéité de la membrane, respectivement avec la surface inférieure de la chambre 9 et ses parois latérales. Au centre de la membrane 11, se trouve un orifice 18 dont l'embouchure, en communication avec l'intérieur de la chambre 9, a une forme d'entonnoir et. dont l'extrémité inférieure est bouchée par la surface inférieure de la chambre 9, lorsque la membrane est dans la position représentée par cette figure. Un ressort 19, par exemple un ressort spirale, dont le diamètre extérieur est sensiblement égal au diamètre intérieur de la chambre 9, s'appuie sur la surface supérieure de la membrane 11 et la repousse dans sa position de repos (représentée par la fig. 1).Inside the chamber 9 is a membrane 11 of circular shape, the diameter of which is preferably very slightly less than the diameter of the chamber 9 of cylindrical shape, so that this membrane can move with low friction inside the room. The upper surface of the membrane 11 is substantially planar. The lower surface has a central boss 12, the flat central zone 13 of which is surrounded by an annular zone 14 which is at a level different from that of the central zone 13, these two levels being connected by an inclined surface 15. In in other words, the central boss 12 has a substantially frustoconical shape, and the thickness of the membrane 11 is greater, at the level of the central zone 13, than that measured at the level of the peripheral zone 14. Seals 16 and 17 seal the membrane, respectively with the lower surface of the chamber 9 and its side walls. In the center of the membrane 11, there is an orifice 18, the mouth of which, in communication with the interior of the chamber 9, has a funnel-shaped shape. whose lower end is blocked by the lower surface of the chamber 9, when the membrane is in the position represented by this figure. A spring 19, for example a spiral spring, the outside diameter of which is substantially equal to the inside diameter of the chamber 9, is supported on the upper surface of the membrane 11 and pushes it back into its rest position (shown in FIG. 1).

Le corps 1 de la pomme de douche comporte d'autre part un conduit d'amenée d'eau sous pression 20, qui communique avec une vanne à deux positions 21 (représentée schématiquement par un cercle), cette vanne ayant deux sorties, l'une 22 (représentée en traits pleins) et l'autre 23 (représentée en traits discontinus). La sortie 22 constitue l'amenée d'eau dans une chambre 24, ménagée dans le corps de la douche au-dessus de la plaque de base centrale 2 et permet, lorsque la vanne 21 se trouve dans' la position appropriée, l'utilisation de la pomme de douche alimentée directement en eau sous pression injectée au niveau de l'amenée d'eau 20.The body 1 of the shower head also has a pressurized water supply conduit 20, which communicates with a two-position valve 21 (shown diagrammatically by a circle), this valve having two outlets, the one 22 (shown in solid lines) and the other 23 (shown in broken lines). The outlet 22 constitutes the supply of water to a chamber 24, formed in the body of the shower above the central base plate 2 and allows, when the valve 21 is in the appropriate position, the use of the shower head supplied directly with pressurized water injected at the water supply 20.

Lorsque la vanne 21 se trouve dans sa deuxième position, la sortie 22 est bouchée et l'eau, introduite par l'amenée d'eau sous pression 20, est dirigée sur la sortie 23 d'où elle pénètre dans une chambre 25 de forme annulaire, et délimitée d'une part par la surface inférieure de la membrane 11 et d'autre part par la surface du fond de la chambre 9. Des canaux 26 (représentés en traits pointillés), permettent de faire communiquer la chambre annulaire 25 avec une chambre 27 également de forme annulaire, ménagée dans le corps 1 de la pomme de douche, et qui communique avec les canaux de sortie 5 et 8 pour permettre l'éjection d'un mélange eau additionnée de produits cosmétiques.When the valve 21 is in its second position, the outlet 22 is blocked and the water, introduced by the pressurized water supply 20, is directed to the outlet 23 from where it enters a chamber 25 of shaped annular, and delimited on the one hand by the lower surface of the membrane 11 and on the other hand by the surface of the bottom of the chamber 9. Channels 26 (shown in dotted lines) allow the annular chamber 25 to communicate with a chamber 27 also of annular shape, formed in the body 1 of the shower head, and which communicates with the outlet channels 5 and 8 to allow the ejection of a water mixture added with cosmetic products.

Le fonctionnement du dispositif mélangeur proprement dit sera expliqué de façon plus détaillée ci-dessous, en référence aux fig. 2A à 2C.The operation of the actual mixing device will be explained in more detail below, with reference to Figs. 2A to 2C.

La fig. 2A représente la pomme de douche en utilisation normale, c'est-à-dire lorsque l'eau sous pression est amenée par le conduit 22 dans la chambre 24 et traverse les orifices 3 de la plaque de base 2. La membrane 11 est dans sa position de repos, c'est-à-dire que le bossage central 12 est en appui contre la surface inférieure de la chambre 9.Fig. 2A represents the shower head in normal use, that is to say when the pressurized water is brought through the conduit 22 into the chamber 24 and passes through the orifices 3 of the base plate 2. The membrane 11 is in its rest position, that is to say that the central boss 12 is in abutment against the lower surface of the chamber 9.

La fig. 2B représente le début de la phase d'utilisation du dispositif mélangeur. La vanne 21 (non représentée sur cette figure) a été mise dans sa seconde position, de telle manière que l'eau sous pression pénètre dans le conduit 23 et dans la chambre 25, de telle manière que la membrane 11 soit soulevée dans le sens des flèches P. La force exercée par la poussée de l'eau, dans la chambre 25, s'oppose à l'action du ressort 19, de telle manière que le bossage central 12 décolle de la surface inférieure de la chambre 9 et dégage l'orifice 18, permettant ainsi l'écoulement d'une quantité déterminée de produits cosmétiques liquides.Fig. 2B represents the start of the use phase of the mixing device. The valve 21 (not shown in this figure) has been put in its second position, so that the pressurized water enters the conduit 23 and the chamber 25, so that the membrane 11 is lifted in the direction arrows P. The force exerted by the push of the water, in the chamber 25, opposes the action of the spring 19, in such a way that the central boss 12 takes off from the lower surface of the chamber 9 and releases the orifice 18, thus allowing the flow of a determined quantity of liquid cosmetic products.

La fig. 2C illustre une phase ultérieure de ce même dispositif en opération. L'eau sous pression, amenée par le conduit 23, a des turbulences dans la chambre 25, qui provoquent de petits déplacements alternatifs de la membrane 11, de telle manière que le savon liquide contenu dans la chambre 9 soit aspiré ou pompé à travers l'orifice 18 dans ladite chambre 25. Le mélange eau et produits cosmétiques, se trouvant dans la chambre 25, s'écoule à travers les conduits 26 dans la chambre 27 et finalement est projeté au travers des canaux 5.Fig. 2C illustrates a later phase of this same device in operation. The pressurized water, brought through the conduit 23, has turbulence in the chamber 25, which cause small alternating movements of the membrane 11, so that the liquid soap contained in the chamber 9 is sucked or pumped through the orifice 18 in said chamber 25. The mixture of water and cosmetic products, being in chamber 25, flows through conduits 26 in chamber 27 and finally is sprayed through channels 5.

Grâce au fait que la pression à l'intérieur d'une alimentation en eau courante n'est pratiquement jamais constante, il se produit des fluctuations de pression dans la chambre 25 et on observe une éjection pulsée du mélange à la sortie des canaux 5. Selon le diamètre de l'orifice 18, on peut contrôler, de façon relativement précise, la quantité de produits cosmétiques qui est mélangée à un volume donné d'eau sous pression. En outre, lorsqu'on donne à la vanne une position intermédiaire entre ses positions extrêmes, il est possible d'éjecter à la fois de l'eau pure par la zone centrale de la pomme de douche, et de l'eau mélangée de produits cosmétiques par sa zone périphérique.Thanks to the fact that the pressure inside a running water supply is almost never constant, pressure fluctuations occur in chamber 25 and a pulsed ejection of the mixture is observed at the outlet of the channels 5. Depending on the diameter of the orifice 18, it is possible to control, in a relatively precise manner, the quantity of cosmetic products which is mixed with a given volume of water under pressure. In addition, when the valve is given an intermediate position between its extreme positions, it is possible to eject both pure water through the central zone of the shower head, and water mixed with products. cosmetics by its peripheral zone.

La fig. 3A représente une autre forme de réalisation du dispositif mélan- eur logé à l'intérieur d'une pomme de douche. Comme précédemment, cette pomme de douche comporte un corps 31 surmonté d'un réservoir 32, ou fermé par un couvercle 33 (représenté en traits pointillés). La base du corps 31 est recouverte d'un capuchon 34 monté sur le corps 31, de telle manière qu'il puisse tourner autour de l'axe de ce corps et subir simultanément un déplacement axial. La rotation du capuchon 34 est limitée de telle manière que ce capuchon puisse occuper deux positions axiales extrêmes représentées respectivement par les fig. 3A et 38.Fig. 3A shows another embodiment of the mixer device housed inside a shower head. As before, this shower head has a body 31 surmounted by a reservoir 32, or closed by a cover 33 (shown in dotted lines). The base of the body 31 is covered with a cap 34 mounted on the body 31, so that it can rotate around the axis of this body and simultaneously undergo axial displacement. The rotation of the cap 34 is limited in such a way that this cap can occupy two extreme axial positions shown respectively in FIGS. 3A and 38.

Lorsque la pomme de douche est équipée d'un réservoir, elle comporte, à l'intérieur du corps 31, un évidement 35 agencé pour recevoir un clapet antiretour 36, dont le rôle est d'éviter que le réservoir ne soit sous pression pendant le fonctionnement du dispositif. Ce clapet antiretour se compose d'un corps 37 en forme de cloche, à l'intérieur duquel est logée une bille 38 qui est soumise à l'action d'un ressort 39 tendant à repousser cette bille vers le bas, contre une butée annulaire 40. Le corps 37 est logé rigidement dans l'évidement 35 et l'intérieur du corps 37 en forme de cloche est en communication avec l'intérieur du réservoir 32. Lorsque la bille 38 est soumise à une pression s'exerçant sur sa partie inférieure, elle est chassée vers le haut en appui contre le siège 41 constitué par un épaulement ménagé sur la paroi intérieure du corps 37, et obstrue la communication avec l'intérieur du réservoir 32. Ce clapet est bien entendu facultatif et ne constitue qu'une sécurité évitant que le réservoir 32, de préférence réalisé en une matière synthétique, ne soit soumis à une pression trop importante.When the shower head is equipped with a reservoir, it has, inside the body 31, a recess 35 arranged to receive a non-return valve 36, the role of which is to prevent the reservoir from being under pressure during the operation of the device. This non-return valve consists of a bell-shaped body 37, inside which is housed a ball 38 which is subjected to the action of a spring 39 tending to push this ball down, against an annular stop. 40. The body 37 is rigidly housed in the recess 35 and the interior of the bell-shaped body 37 is in communication with the interior of the reservoir 32. When the ball 38 is subjected to a pressure exerted on its part lower, it is driven upwards bearing against the seat 41 constituted by a shoulder formed on the inner wall of the body 37, and obstructs the communication with the interior of the reservoir 32. This valve is of course optional and only constitutes a safety element preventing the reservoir 32, preferably made of a synthetic material, from being subjected to excessive pressure.

A l'intérieur du corps 31 de la pomme de douche et en-dessous de l'évidement 35, est ménagée une chambre 42, dans laquelle est logée une membrane 43 et un ressort spirale 44 tendant à appuyer la membrane 43 contre une plaque de retenue 45 solidaire, par l'intermédiaire d'une colonne centrale 46, du capuchon 34. Une embouchure 47 communique avec un conduit intérieur d'amenée d'eau 48 qui débouche à l'intérieur d'une chambre 49, et est évacuée au travers des orifices 50 ménagés dans la plaque de base du capuchon 34, lorsque ce capuchon se trouve dans la position illustrée par la fig. 3A. Dans cette position, la douche est utilisée sans mélangeur, c'est-à-dire que l'eau, injectée dans le conduit d'amenée 48, est directement évacuée, sans être mélangée à un produit cosmétique, à travers les orifices 50.Inside the body 31 of the shower head and below the recess 35, a chamber 42 is formed, in which is housed a membrane 43 and a spiral spring 44 tending to press the membrane 43 against a plate of retainer 45 secured, via a central column 46, to the cap 34. A mouth 47 communicates with an internal water supply duct 48 which opens out inside a chamber 49, and is evacuated to the through orifices 50 formed in the base plate of the cap 34, when this cap is in the position illustrated in FIG. 3A. In this position, the shower is used without a mixer, that is to say that the water, injected into the supply conduit 48, is directly evacuated, without being mixed with a cosmetic product, through the orifices 50.

La fig. 3B représente le capuchon 34 dans sa position inférieure, c'est-à-dire dans une position permettant le mélange eau et produits cosmétiques.Fig. 3B shows the cap 34 in its lower position, that is to say in a position allowing the mixing of water and cosmetic products.

Comme précédemment, la membrane 43 comporte un bossage central 51 traversé par un orifice 52. Le ressort 44 a tendance à repousser la membrane 43 contre la plaque de base 45, de façon à obstruer l'orifice et empêcher l'écoulement de savon liquide contenu dans la chambre 42, vers une chambre 53 délimitée par la surface inférieure de la membrane 43 et la surface supérieure de la plaque 45.As before, the membrane 43 has a central boss 51 crossed by an orifice 52. The spring 44 tends to push the membrane 43 against the base plate 45, so as to obstruct the orifice and prevent the flow of contained liquid soap in chamber 42, towards a chamber 53 delimited by the lower surface of the membrane 43 and the upper surface of the plate 45.

Lorsqu'on dévisse le capuchon 34 vers sa position inférieure, la plaque 45 vient en butée contre la paroi inférieure 54 du conduit d'amenée 48, de telle manière que l'eau amenée par ce conduit pénètre dans la chambre 53, fait vibrer la membrane 43 et provoque l'écoulement de savon liquide à travers l'orifice 52. Le mélange obtenu est déversé dans la chambre 49 disposée sous la plaque de base 45, grâce à une ouverture 55 ménagée entre la plaque 45 et la paroi adjacente du corps 31 dela pomme de douche. Un joint torique 56 assume l'étanchéité entre le capuchon 34 et le corps 31 de la pomme de douche. Un second joint torique 57 est ménagé dans une gorge circulaire réalisée à la base de la membrane 43 et assure l'étanchéité entre cette membrane et la plaque 45.When the cap 34 is unscrewed towards its lower position, the plate 45 abuts against the lower wall 54 of the supply duct 48, so that the water supplied by this duct enters the chamber 53, vibrates the membrane 43 and causes the liquid soap to flow through the orifice 52. The mixture obtained is poured into the chamber 49 disposed under the base plate 45, thanks to an opening 55 formed between the plate 45 and the adjacent wall of the body 31 of the shower head. An O-ring 56 assumes the seal between the cap 34 and the body 31 of the shower head. A second O-ring 57 is provided in a circular groove made at the base of the membrane 43 and provides sealing between this membrane and the plate 45.

La fig. 4 représente une variante assez voisine, quoique simplifiée du dispositif des fig. 3A et 3B. Dans ce dispositif, la pomme de douche comporte un corps 61 fermé par un bouchon 62 vissé ou emboîté par clip- sage d'un bourrelet périphérique 63 dans une gorge circulaire de forme complémentaire 64.ménagée dans une paroi 65 dudit corps 61. L'étanchéité entre le bouchon 62 et la paroi 65 est assurée par un joint torique 66.Fig. 4 shows a fairly similar, although simplified variant of the device of FIGS. 3A and 3B. In this device, the shower head comprises a body 61 closed by a plug 62 screwed or fitted by clipping a peripheral bead 63 into a circular groove of complementary shape 64. Arranged in a wall 65 of said body 61. sealing between the plug 62 and the wall 65 is ensured by an O-ring 66.

Comme dans l'exemple des fig. 3A et 3B, le corps 31 délimite une chambre 67 servant de réservoir pour le savon liquide. Cette chambre communique avec l'intérieur évidé 68 du bouchon 62 ce qui augmente sa capacité. A l'intérieur de la chambre 67 sont disposés d'une part une membrane 68 sensiblement identique à la membrane 43 des figures 3 et un ressort spirale 69 qui prend appui sur un épaulement 70 ménagé à l'extrémité supérieure de la chambre 67, et sur la face supérieure de la membrane 68. Comme précédemment, des joints 71 et 72 assurent l'étanchéité entre la membrane et, respectivement les parois latérales et le fond de la chambre 67.As in the example of figs. 3A and 3B, the body 31 defines a chamber 67 serving as a reservoir for the liquid soap. This chamber communicates with the hollowed-out interior 68 of the plug 62 which increases its capacity. Inside the chamber 67 are arranged on the one hand a membrane 68 substantially identical to the membrane 43 of FIGS. 3 and a spiral spring 69 which bears on a shoulder 70 formed at the upper end of the chamber 67, and on the upper face of the membrane 68. As before, seals 71 and 72 provide sealing between the membrane and, respectively, the side walls and the bottom of the chamber 67.

Le fond de la chambre 67 est en fait constitué par une plaque 73, solidaire par l'intermédiaire d'un support central 74, d'un capuchon 75, adapté à l'extrémité inférieure du corps 61 et susceptible de se déplacer de façon limitée en rotation et en translation par rapport audit corps. Comme précédemment, la plaque comporte un fraisage 76 qui permet l'écoulement de l'eau mélangée de savon dans la chambre 77 disposée en dessous de la plaque 73, et à travers les orifices 78 ménagés dans la base du capuchon 75. Le capuchon comporte des rainures hélicoïdales 79 qui s'engagent dans un bourrelet périphérique 80, agencées de telle manière qu'une rotation limitée (par ex. un quart de tour) du capuchon amène ce dernier de sa position haute (représentée par la figure) à sa position basse (non représentée).The bottom of the chamber 67 is in fact constituted by a plate 73, secured by means of a central support 74, of a cap 75, adapted to the lower end of the body 61 and capable of moving in a limited manner in rotation and in translation relative to said body. As before, the plate has a milling 76 which allows the water mixed with soap to flow into the chamber 77 arranged below the plate 73, and through the orifices 78 formed in the base of the cap 75. The cap has helical grooves 79 which engage in a peripheral bead 80, arranged in such a way that a limited rotation (eg a quarter turn) of the cap brings the latter from its high position (represented by the figure) to its position low (not shown).

Comme pour le dispositif des figures 3, le corps 31 comporte un orifice d'amenée d'eau 81 qui communique avec un passage 82 permettant de relier l'orifice 81 avec la chambre 77 ou la chambre 83 située entre la plaque 73 et la membrane 68. Dans cet exemple de réalisation, le passage 82 comporte un évidement annulaire ménagé dans le corps 31.As for the device in FIGS. 3, the body 31 includes a water supply orifice 81 which communicates with a passage 82 making it possible to connect the orifice 81 with the chamber 77 or the chamber 83 located between the plate 73 and the membrane 68. In this embodiment, the passage 82 includes an annular recess formed in the body 31.

Par rapport au dispositif des figures 3, la présente réalisation se distingue par l'absence de la soupape à bille qui n'est en fait utile que lorsque le corps de la pomme de douche comporte un réservoir, et peur éviter la mise sous pression de ce réservoir pendant le fonctionnement du dispositif.Compared to the device of FIGS. 3, the present embodiment is distinguished by the absence of the ball valve which is in fact only useful when the body of the shower head comprises a reservoir, and in order to avoid the pressurization of this tank during the operation of the device.
