Definitions

  • 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.
  • 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.
  • This well known device has a number of drawbacks.
  • 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.
  • 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.
  • a very large amount of water is used for a very small amount of liquid soap.
  • 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.
  • the mixing device 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 .
  • 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.
  • 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.
  • 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.
  • 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 membrane 11 of circular shape 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.
  • 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.
  • 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).
  • 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.
  • valve 21 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.
  • 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.
  • 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.
  • 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.
  • Fig. 3A shows another embodiment of the mixer device housed inside a shower head.
  • 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.
  • the shower head 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.
  • 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 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.
  • 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.
  • 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.
  • the plate 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.
  • Fig. 4 shows a fairly similar, although simplified variant of the device of FIGS. 3A and 3B.
  • 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.
  • a plug 62 screwed or fitted by clipping a peripheral bead 63 into a circular groove of complementary shape 64.
  • 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.
  • 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.
  • seals 71 and 72 provide sealing between the membrane and, respectively, the side walls and the bottom of the chamber 67.
  • 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.
  • 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).
  • 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.
  • the passage 82 includes an annular recess formed in the body 31.
  • 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.
