Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flush-type toilet chemical infusion device, and more particularly, to a flush-type toilet with a branch attached to a flush-water pipe for urine flushing. The present invention relates to a device for injecting a certain amount of chemicals such as a component for preventing stone adhesion and a disinfecting component for a toilet when the toilet is washed with water.

[Conventional technology]

 A flush toilet that branches and installs in the flush water pipe of a flush toilet
Water inflow and outflow by a float valve as a dexterous drug injection device
For dissolving liquid drug in water and injecting it into toilet bowl
Is disclosed in British Patent 1,069,213.
Mick It is commercially available under the trade name.

 On the other hand, the present applicant has applied urine stones to the
As an agent to prevent adhesion, solid acid and sublimable substance
(See Japanese Patent Application Laid-Open No. 62-038299),
Launched (Product name: Take One ).

[Problems to be solved by the invention]

The cited drug injection device, as shown in FIG.
A valve (16) directly connected to the float (14) is provided at the bottom of the body (13). When the toilet is flushed, flush water is supplied into the body (13) through the connection pipe (17), and the liquid level in the body is constant. Has a mechanism in which the inflow of water stops at the depth of the water, and the water in the main body flows out to the toilet from the time when the inflow pressure of the water at the end of the flushing decreases. There are no major drawbacks. Inside the main body, a container of a liquid drug mainly composed of a quaternary ammonium salt is installed upside down, and the drug is leached into the main body through a sponge (12) of the container (11), dissolved in water, and washed with water. Sometimes a drug solution is injected into the toilet. However, the germicidal detergent containing a quaternary ammonium salt as a main component used in this device has an insufficient effect of preventing urine stones from adhering to the toilet trap. Further, since the medicine in the container is diluted by replacing it with water, the substantial injection amount of the medicine into the toilet gradually decreases, and the antifouling and sterilizing effect of the toilet decreases.

On the other hand, since the molded body composed of the above-mentioned solid acid and the sublimable substance is used directly in the trap section of the toilet or contained in a specific container and used in contact with waste during the chemical exchange work, it is preferable. Not a work style.

An object of the present invention is to provide a flush-type toilet infusion device having the same function as the above-mentioned prior art.

I do. At the end of flush of flush water, 2: the pressure in the valve chamber decreases, 7: the check valve is opened, and 1: the water in the main body flows out into the flush water pipe through the connection pipe.

Therefore, by adding the medicine into the main body, the medicine can be injected into the toilet together with the water when the water flows out. It is preferable that a mechanism for quantitatively supplying a drug such that the amount of the drug injected in one flush is constant is provided internally, but a molded article of a mixture comprising the above-mentioned solid acid, sublimable substance and water-soluble organic substance is preferably used. : By putting it into the main body, it is possible to inject a substantially constant amount of the active ingredient into the toilet bowl for each flush. In the solid molded body, when the inside of the main body is empty, the sublimable substance as the component sublimates, a layer of a water-soluble component is formed on the surface, and when the water is supplied, the water-soluble component ( The active ingredient) layer is dissolved in water, and a sublimable substance layer is formed on the surface. Accordingly, the sublimation speed of the sublimable substance can be controlled by the opening degree of the slit 9 provided on the upper lid 8 and the amount of the active ingredient dissolved in water by one flush can be controlled. For this purpose, it is preferable to provide a slit opening adjustment mechanism. Further, it is preferable to provide a drug or drug container guide 10 to prevent the drug or the drug container from moving or falling within the main body.

〔Example〕

 The present invention will be described in more detail by way of examples.

However, the scope of the present invention is not limited by the following examples.

(1) Pharmaceutical injection device for flush-type toilets The device shown in Fig. 1 has an effective water storage capacity (water storage capacity when the float valve is closed) of 200 ml, and the main part is made of vinyl chloride. Was connected to a connection pipe branched from a flush water pipe of a flush toilet.

 9: The slit has a fixed opening.

In addition, a liquid level gauge was attached to the side of the main body so that the liquid depth when storing water could be measured.

(2) Water storage measurement Using the device prepared in the above item (1), the flush water of the flush toilet is repeatedly flushed to measure the liquid level when the toilet is full,
The amount of water stored at the time of flushing the washing water was calculated.

As a result of repeating the flush 10 times, the maximum and minimum errors of the water storage amount with respect to the design value were within ± 5%.

〔The invention's effect〕

As shown in the above embodiment, the flushing water flushing device of the present invention has a substantially constant flushing water storage amount.

Therefore, by combining this device with the constant-quantity supply mechanism of medicine, a certain amount of medicine can be injected into the toilet bowl every flush of the washing water.

In addition, there is no need to administer the medicine into the dirty toilet bowl, and anyone can perform the medicine administration operation.

The present invention provides a device that branches and is attached to a flush water pipe of a flush toilet and injects a certain amount of medicine into the toilet every flush of flush water, and has public health and industrial significance. , Extremely large.
