Description
- This invention relates to a device for delivering water admixed with a detergent liquid, particularty for hygiene and sanitation applications.
- Known, in the field of hygiene and sanitation appliances. are shower dispensers having a hand-grip to facilitate their use, and which deliver water through a small plate having a plurality of holes for providing a shower dispensing mode.
- Also known are shower dispensers incorporating devices, commonly termed "aerators", which are connected to the ends of a dispenser to provide for the delivery of mixed water and tiny air bubbles.
- Furthermore, devices are known for delivering scented water, which generally consist of dispensers wherein a suitable seat is provided in contact with the water for the introduction of solid flavouring tablets which dissolve slowly on delivery.
- Such dispensers, while generally showing no disadvantages regarding their ordinary use, are unsuited to dispense mixed water and soap.
- It is the primary aim of this invention to provide a device which can deliver water admixed with a detergent liquid for washing the skin with soft detergent lather and such .as to enable a uniform distribution of the lather such as was produced in the past by rubbing the soap over the skin.
- Within the above aim, it is an object of this invention to make a person's washing operation more pleasant by arranging for the distribution of lather under a slight pressure. which can later be rubbed against one's skin by means of a sponge or otherwise for proper hygiene.
- The above aim, and these and other objects, are achieved by a device for delivering water admixed with a detergent liquid, particularly for hygiene and sanitation applications, including a shower dispenser, characterised in that it comprises a detergent liquid reservoir in communication with a channel for feeding water into said reservoir and to a delivery end of said shower dispenser, a means being provided for connecting said reservoir to said delivery end.
- Further features and advantages of the invention will become apparent from the description of some preferred but not exclusive embodiments of the inventive device, with reference to the accompanying illustrative drawings, where:
- Figure 1 is a perspective view of a first embodiment of the device according to the invention;
- Figure 2 is a front elevation view of a first embodiment of the device of this invention;
- Figure 3 is an enlarged sectional view of part of Figure 2 taken along the line III-III, showing the inventive device during a first operation phase;
- Figure 4 is an enlarged sectional view of part of figure 2 taken along the line III-III and showing the inventive device during a second operation phase;
- Figure 5 is a section taken similarly to Figures 3 and 4 of a second embodiment of the device according to the invention;
- Figure 6 is a section taken similarly to Figures 3 and 4 of a third embodiment of the inventive device;
- Figure 7 is a section taken similarly to Figures 3 and 4 of a fourth embodiment of the inventive device; and
- Figure 8 is a section taken similarly to Figures 3 and 4 of a fifth embodiment of the inventive device.
- With reference to the drawing figures, the device o this invention comprises a shower dispenser, generally des. ignated with the
reference numeral 1, which has a hand.grip 2 for handling convenience in use, and adelivery enc 3. - Internally of the
shower dispenser 1 there is provided according to the invention, a detergentliquid reservoir 4 which is in communication with achannel 5 for feeding water both to the reservoir anddelivery end 3. - The
reservoir 4 is also in communication with the outside through anopening 6 which may be shut off by means of aremovable plug 7 to allow filling with a deter. gent liquid. - With particular reference to Figures 1 to 4, the
delivery end 3 comprises anaerator 8 for delivering lather and a small plate 9, which extends externally of an coaxially with the aerator and has a plurality of water delivery holes. - The
reservoir 4 is in communication with thechannel 5 through asmall tube 10, which extends internally of the reservoir, and with thedelivery end 3 through aconduit 11 1 carried on the interior of asmall shaft 12, which communicates with the reservoir through ahole 13 and opens in the proximity of thedelivery end 3. Advantageously, thesmall shaft 12 is movable parallel to its own axis from an open position, whereat thehole 12 is located inside the reservoir and can, therefore, supply the detergent liquid to the delivery end, to a closed position whereat thehole 8 is brought to the exterior of the reservoir so as to shut off the delivery of detergent liquid. - Expediently, moreover, the
small shaft 12 cames close to the delivery end aswitch gasket 14 which, is moving with the small shaft between two abutments, causes in these two positions water to be conveyed respectively either to the aerator or the small plate. - The
small shaft 12, and hence theconduit 11, which constitute the means for connection according to this invention, are controlled from the outside of the shower dispenser through an actuatingknob 15 which is rigid with thesmall shaft 12. - Of course, sealing gaskets are provided, respectively 16,17 and 18, to prevent the detergent liquid from leaking toward the delivery end. Also provided are
more gaskets - With reference to Figure 5, the
small shaft 12 is actuatable from the outside by turning amovable end 21 of the shower dispenser, thereby, motion is transmitted to the small shaft through ascrew nut 22, carried on the movable end, which engages with a thread. 23 carried on thesmall shaft 12. - In the embodiment shown in Figure 6, switching is achieved by splitting the
channel 5 into two secondary channels, 24 and 25 respectively, of which one is in com- municaton with thereservoir 4 and the other is in communication with thedelivery end 3. Close to the split point, there is provided aswitch valve 26 which admits water to only one of the two secondary channels to provide for the delivery of either water or lather. In this case, the connection means according to the invention comprises a small fixedcylinder 27 through which there extends an internal conduit 28. - In the embodiment shown in Figure 7 switching is accomplished by turning the head of the shower dispenser, and accordingly, two delivery ends are provided which operate alternatively. In this case, the
small tube 10 is replaced with theintake 29 which may be shut off by the rotation because it is located offcentered with respect to the axis of offixed pin 30 about which the head 31 of the dispenser is rotatable. - In this case, the means for the connection according to this invention comprises the
curved tube 32. - In the embodiment shown in Figure 8 no switch positions are provided, but there occurs the delivery of lather until the detergent liquid is exhausted and accordingly, the means for the connection according to the invention comprises merely a
connection pipe 33. - The operation of the device according to the invention is apparent from the foregoing description. With reference to Figures 3 and 4, after the
reservoir 4 is filled with detergent liquid the reservoir is closed and the dispenser is ready for use. - Holding the
knob 15 at the position shown in Figure 3, water will enter the reservoir from thechannel 5 and asmall tube 10 and pressurise the detergent liquid becoming mixed with it. - A slight negative pressure occurs at the delivery end owing to the presence of the
aerator 8 which draws air from the outside, and therefore, the detergent liquid admixed to water will flow through thehole 13 and reach the delivery end where it is further admixed to water and air, thus forming the lather which is delivered from the aerator. - When the delivery of lather is to be discontinued it will be sufficient to operate the actuating knob and thus avoid connecting the reservoir to the delivery end. In this case, the movement of the
switch gasket 14 causes the water flow issuing from the holes in the small plate 9 to be deflected. - in tne other embodiments. switching. except in the type shown in Figure 8 which is not provided with it, takes place either by turning the movable end 21 (Figure 5) or operating the switch valve 26 (Figure 6) or turning the head 31 of the dispenser (Figure 7).
- It has been found in practice that the device of this invention enables automatic mixing of the outflowing water with such detergent liquids as shampooes, liquid soap, bath gel, etc.. it being possible to discontinue the delivery of lather and oniy admit water for delivery.
- The invention herein is susceptible to many modifica- lions and changes without departing from the purview of the inventive concept. Thus, as an example, it would be possible to replace the
small tube 10 with a simple intake equipped with a check valve. Furthermore, all of the details arc replaceable with other technically equivalent elements. - In practicing the invention, any materials, and dimensions. may be used contingent on requirements and the state of the art.
