Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a chemical solution supply device that is installed on the top of a hand wash basin, washbasin, etc., and supplies a chemical solution such as a soap solution or a disinfectant solution.

(Prior art and its problems) Conventional chemical solution supply devices have a system in which a chemical solution is supported by a support installed at the upper corner of a washbasin or a basin, and a hollow discharge pipe is attached to the lower end of this chemical solution tank so that it can move up and down. There are some types that have a structure in which when the discharge pipe is pushed up by hand, the valve opens and the chemical liquid drips onto the palm of the hand.In addition, there are also types in which the chemical liquid tank is housed within the wall, etc.
The chemical solution is guided from this chemical tank through a communication pipe to a nozzle installed above the washbasin, etc., and when the push button provided on the nozzle is pressed by hand, the valve inside the nozzle opens and the chemical solution drips from the nozzle. What it does is known.

However, in the conventional example described above, in the former structure in which the chemical solution tank is supported by a support, the chemical solution tank limits the range of movement of the user over the washbasin, and becomes a nuisance in small washbasins, etc. There was a problem. In addition, the latter, which uses a nozzle with a push button, is cumbersome to use because when using a chemical solution, one must press the push button with one hand and receive the chemical solution discharged from the nozzle with the other hand. When the nozzle is housed inside a washbasin, etc., it is necessary to provide a hole for exposing the push button in addition to the hole for exposing the nozzle from the surface, which poses the problem of making it difficult to remodel the washbasin. It was hot.

(Means for Solving the Problems) The present invention was devised in view of the above-mentioned conventional problems, and its purpose is to provide a chemical liquid supply device that is in good use condition and can be easily installed. , the gist of the device is to have a cylindrical device body that is fixed to the upper part of a washbasin, etc., and has a ventilate-like hole formed inside to allow the chemical solution introduced from the chemical solution tank to drip downward little by little, and the device body. A substantially funnel-shaped lever is attached to the lower part of the device so as to be able to rotate forward, and the lever is provided inside the lever and normally comes into contact with the lower end of the device body due to the biasing force of a spring, allowing the chemical solution to flow downward. The valve body is configured to include a valve body that prevents the chemical from flowing out downwardly when the lever is rotated forward.

(Function) The chemical liquid is introduced from the chemical liquid tank into the inside of the device main body which is fixedly installed in the upper part of the washbasin, but the chemical liquid is dripped little by little into the bottom of the device main body due to the through hole in the device main body. , a large amount of chemical solution is not dropped at once. In addition, a valve body is provided inside the lever that is rotatably attached to the lower part of the device body, and this valve body normally prevents the chemical solution dripping from the device body from flowing out due to the biasing force of a spring. At the same time, when the lever is rotated forward, this valve body opens and the medicinal liquid is dripped downward, so when the lever is rotated forward, a small amount of the medicinal liquid is applied to the palm of the hand with the lever rotated forward. It is extremely easy to receive and use.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a cross-sectional configuration diagram of the chemical liquid supply device in an installed state, and FIG. 2 is a front view thereof. Further, FIG. 3 is a diagram showing the overall layout of the device when it is attached to a washbasin or the like.

In the figure, a curved accommodating part 1a is formed at the upper end of the washbasin 1, and the device main body 3 constituting the chemical solution supply device 2 can be attached in this accommodating part 1a from the back side in a substantially concealed manner. . That is, the device main body 3 is formed in a cylindrical shape, and has an open chemical solution inlet 3a formed at the upper end, and a downwardly opened chemical solution chamber 3c formed at the lower end, which is connected to the chemical solution inlet 3a. The chemical solution chambers 3c are communicated with each other through a ventilate-shaped through hole 3b. Further, the lower end portion of the device main body 3 forms a semicircular seat portion 3d.

A flange portion 3e is formed in the lower part of the device main body 3 to project outward, and a pair of shaft support plates 3f, 3f projecting downward are integrally formed on the front side of the flange portion 3e. There is. Therefore, in order to attach this device main body 3 to the accommodating part 1a of the washbasin, insert the device main body 3 from below into the mounting hole 1b formed in the vertical direction in the washbasin 1, and then The device main body 3 is firmly fixed to the washbasin 1 by screwing together the packing 6 and the nut 8 from the upper part of the device body 3 with the gasket 5 interposed therein, and tightening the nut 8 to the washbasin 1. I can do it.

A rotating shaft 9 is inserted through the pair of shaft support plates 3f, 3f of the device main body 3, and a funnel-shaped lever 4, which is supported at both ends of the rotating shaft 9 and is open at the top, is attached to the front side. It is attached to the device main body 3 so as to be rotatable. A drip hole 4b through which a chemical solution can pass is formed at the lower end of this lever 4.
A convex portion 4a that protrudes inward is formed inside. The entire lever 4 can be made of cast metal or the like.

Further, a fixing plate 11 is attached to the upper surface side of the convex portion 4a of the lever 4 via screws 15, and a valve body 14 is integrally attached to the upper surface of the fixing plate 11 via screws 12 and washers 13. ing.
Further, a spring 10 is attached to the rotating shaft 9 in a wound manner, the lower end of the spring 10 is locked to a fixed plate 11, and the upper end of the spring 10 is locked to the main body 3 of the device. ing. Therefore,
Due to the biasing force of the spring 10, the lever 4 is always biased toward the rear side of the wash basin 1, and at the same time, the fixing plate 11 is also biased toward the lower end of the device main body 3, and the valve body 14 is pushed toward the bottom of the device main body 3. 3 is in contact with the seat portion 3d at the lower edge.

As shown in FIG. 3, a communication tube 16 is connected to the chemical solution introduction port 3a of the chemical solution supply device 2, and a tank attachment part 17 formed at the tip of the communication tube 16 is used to receive the chemical solution. The stored chemical liquid tank 18 is attached, and the chemical liquid in the chemical liquid tank 18 is transferred to the communication pipe 1.
6 and is introduced into the device main body 3.

The chemical solution tank 18 can be taken in and out of the wall in a concealed manner through an opening 19a of a counter 19 formed in a washroom or the like, and the chemical solution tank 18 can be taken out from the opening 19a and replaced as needed. It is.

In such a configuration, the chemical solution tank 18, the communication pipe 16, and the chemical solution supply device 2 can be installed in a concealed manner on the wall surface and the washbasin 1, and these components can be hidden from the front side to improve the appearance of the washroom. can be finished with a clean appearance.
In addition, 20 in FIG. 3 is a water faucet spout.

In the chemical solution supply device 2 configured in this way, when a user standing in front of the washbasin 1 puts his hand on the lever 4 and rotates the lever 4 forward, the valve body 14 is moved together with the fixed plate 11. It rotates forward, and at this time, the chemical liquid chamber 3c of the device main body 3 is opened, and the chemical liquid in the chemical liquid chamber 3c flows downward and flows out from the drip hole 4b of the lever 4 to the washbasin 1 side. Therefore, by placing a hand near the dripping hole 4b, the chemical liquid dripped from the dripping hole 4b can be received in the palm of the hand, and the chemical liquid can be used effectively. In addition, from the chemical liquid inlet 3a to the chemical liquid chamber 3
Since the flow rate of the chemical liquid flowing down into c is limited by the through hole 3b, the chemical liquid flows down little by little, and a large amount of the chemical liquid does not flow down at once, which effectively prevents wasteful use of the chemical liquid. .

(Effects of the invention) The chemical solution supply device of the present invention has a cylindrical shape that is fixed to the upper part of a washbasin, etc., and has a ventilate-like hole formed inside to allow the chemical solution introduced from the chemical tank to drip downward little by little. A device body, a substantially funnel-shaped lever attached to the lower part of the device body so as to be rotatable forward, and a lever provided inside the lever, which is normally brought into contact with the lower end of the device body by the biasing force of a spring. By having a valve body that contacts the valve body to prevent the chemical liquid from flowing downward and allows the chemical liquid to flow downward when the lever is rotated forward, the lever can be moved forward with one hand. By rotating the device, the chemical solution can be discharged onto the palm of the hand, making it extremely easy to use the drug solution.

In addition, the chemical solution supply device of the present invention requires only one hole for fixing the device body to the wash basin.
There is no need to separately provide a hole to expose the push button as in the conventional case. Therefore, it is possible to easily modify the washbasin or the like in order to attach the chemical solution supply device.

Furthermore, since only the lever can be exposed to the outside, it has the effect of making the area around the washbasin neat and clean and improving the aesthetic appearance of the washroom or the like.
