JPH01295931A - Drug injector for flush urinal stall - Google Patents

Abstract

PURPOSE:To make it possible to replenish drugs under sanitary condition and to improve utility of the drugs as well, by installing a container containing the drugs to a feed-water pipe of a urinal stall and by letting solution run into the feed-water pipe from the lower side, while letting the water run down from the upper side. CONSTITUTION:To a feed-water pipe 5 of a urinal stall 1, a drug container 13 containing drugs like urolith preventing drug 17 or the like is installed and covered with a detachable water-penetrated cover 21 with a plurality of holes 20 provided thereupon. Then, an inlet 22, connected to the water-penetrated cover 21 at the upper part, and an outlet 23, connected to the surface of a base board 13a of the container 13 at the lower part, are both bored to the feed-water pipe 5. When letting washing water flow after urination, the water runs into the container 13 through the holes 20 and dissolves the drugs little by little. Then, the solution runs into the feed-water pipe 5 lagging behind direct-running-down water. After the urinal stall is washed by plain water, the solution in low concentration runs down, and finally, the solution in appropriate concentration stays inside a trap.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a drug addition device for a flush toilet that mixes a drug such as a urinary stone inhibitor into the flush water of the flush toilet.

(B) Prior art Conventionally, instead of a sana, a container with a large number of holes and filled with a urinary stone preventive agent or other drug was fitted to the outflow part of the toilet bowl so that the drug would be gradually dissolved by the flushing water. I have already proposed something like this.

(c) Problems to be solved by the invention The method of fitting the container filled with the urinary stone preventive agent etc. to the mounting position of the sana requires the work of removing the container with urine still attached when replacing the container. In addition, a large amount of washing water washes away the urinary stone preventive agent, resulting in a large amount of wasted water.In order to obtain the desired concentration, the solid drug must be easily dissolved. However, if you do so, there is a problem that it will dissolve rapidly.
If it is made difficult to dissolve, there is a problem that the concentration of the drug in the washing water remaining in the trap decreases, making it impossible to obtain the desired effect.

(D) Means for Solving Problems The present invention provides a method for attaching a medicine container to the water supply pipe of a toilet bowl, attaching and detaching a water passage cover having a plurality of holes to at least the upper part of the medicine container, By drilling the pipe with an inflow hole that communicates with the upper water flow lid and an outflow hole that communicates with the bottom plate, it is possible to replenish the medicine in a clean state, and reduce the amount of water that comes into contact with the medicine. At the same time, the above-mentioned problem was solved by delaying the outflow timing of the solution.

(e) Effect After putting the medicine into the medicine container, fit the water passage lid.

When the wash water flows out after urinating, a portion of it flows out from the inflow hole of the water supply pipe onto the water flow lid and disperses, and then flows into the drug container through multiple holes and gradually dissolves the drug. However, this solution flows into the water supply pipe from the outflow hole with a delay in timing.

Therefore, in the initial stage, there is almost no drug dissolved in the flushing water flowing down the toilet bowl, and the cleaning water is used exclusively for cleaning, and in the final stage, the solution flows down the toilet bowl and then flows through the outlet and the trap. The solution having approximately a predetermined concentration that flows out at the end stays in the trap and prevents the formation of urinary stones, or if the drug is other, it exerts a corresponding medicinal effect.

(F) Embodiment An embodiment of the present invention will be described with reference to the drawings. 1 is a urinal, the upper inlet is connected to a water supply pipe 5 having a valve 3 with a button 2, and the lower part is A drain pipe 7 having a trap 6 is connected to the outlet.

Then, a part of the middle part of the water supply pipe 5 is cut out, and a branch pipe 8 is interposed in this cut part.
It consists of a main part 8a with a smaller inner diameter and a larger outer diameter, and an upper connecting part 8b and a lower connecting part 8c that fit into the outer peripheral part of the water supply pipe, and a conical cylindrical tongue piece is attached to the inner periphery of the upper end of the main part 8a. 10 is provided protrudingly, and at the bottom there is a tapered tongue piece 11 that is narrower at the bottom.
A circular protrusion 12 having a cross section shaped like a letter is provided on the upper inner circumferential surface of the lower connecting portion 8c, and the lower portion thereof is expanded.

The drug container 13 is composed of a bottom plate 13a and a side plate 13b, and a hole at the center of the bottom plate 13a is fixed to the upper outer periphery of the lower connecting portion 8c, and has an appropriate shape such as a rectangle, a semicircle, or an ellipse in plan view. , and there is a slight M on the bottom plate 13a.
A receiving plate 16 having a large number of holes 15 with gaps is fixed thereto, or it is removably mounted on a rib protruding from the inner periphery of the side plate 13b. Agent 1
A water passage plate 21 containing a plurality of holes 20φ in which a rib 18 protruding from the upper part of the inner circumferential surface of the side plate 13a and a rib 19 protruding from the upper outer periphery of the main part 8a is filled with a 7φ or appropriate chemical.
It is mounted so that it can be inserted and removed.

On the left and right sides of the upper part of the diverter tube 8, there are inflow holes 22 for communicating the upper surface of the base of the tongue lO with the upper surface of the water passage cover 21.
1 to 2 or 3 holes are drilled on the left and right sides, and 1 to 2 outflow holes 23.Q are bored on the left and right sides of the lower part.

The branch pipe 8 has a main portion 8a, an upper connecting portion 8b, and a lower connecting portion 8c.
It is best to separately mold them from vinyl chloride or other synthetic resin, and at that time, protrude circular protrusions that fit on the inside and outside of their connecting parts, and then fit them together and bond them with adhesive. .

Next, to explain the operation, when you press the button after urinating, the valve 3 opens for a certain period of time, and the flushing water flows down the water supply v5 to clean the urinal 1, and passes from the discharge port through the trap 6 to the discharge pipe 7. leaks to.

At that time, a part of the washing water that has flowed down is diverted by the tongue piece 10 and flows from the inflow hole 22 onto the water passage lid 21, and as it spreads on the water passage lid 21, it leaks from the guard hole 20. to dissolve the drug, and the solution flows through the holes 15 of the receiving plate 16 into the drug container 1.
It flows down onto the bottom plate of No.3.

In this state, the cleaning water flowing down inside the branch pipe 8 is constricted by the tapered tongue piece 11, and a space is formed directly below the tongue piece 11, which expands downward, so that a suction force is generated near the tongue piece 11. As a result, the solution on the bottom plate 13a of the drug container 13 is sucked and flows into the lower part of the water supply pipe 5, and as a result, the washing water mainly performs washing at the beginning of the outflow, and the drug solution is mixed in at the end. Since it adheres to the outlet and stays in the trap 6, it is possible to prevent urinary stones from forming in the vicinity.

In addition, when replenishing medicine, the water passage lid 21 is pulled up, the tablet-formed medicine is put into the medicine container 13, and the water passage lid 21 is closed, but if one side of the water passage plate 21 is hinged. opens and closes,
If a groove is provided on the − side to provide a sliding surface, insert and remove it.

Furthermore, if the bottom plate 13a of the drug container 13 is formed into a funnel shape, the solution will more easily flow into the lower connecting portion 8C.

Furthermore, if the receiving plate 16 is made removable, the bottom of the container can be easily cleaned. In addition, the holes 20,1
5. The number of inflow holes 22 and outflow holes 23 or their diameters may be changed as appropriate depending on the solubility of the drug, the flow rate of washing water, and other factors.

In the above-mentioned embodiment, the drug container 13 surrounds the water supply pipe 5, but it may be arranged to protrude from the water supply pipe on any side other than the wall side, and the holes 20 of the water passage cover 21 surround the water supply pipe 5. 5
By making the diameter of the closer one smaller or increasing the interval, the cleaning water flowing in from the inflow hole 22 flows almost evenly throughout the drug container 13.

Further, the outflow of the solution can be further delayed by making the holes 20 or 15 smaller or by using other outflow suppressing means.

(G) Effects of the Invention As described above, the present invention attaches the drug container 13 to the water supply pipe 5 of the toilet bowl, and removably attaches the water passage lid 21 having a plurality of holes 20 to at least the upper part of the drug container 13. However, since the water supply pipe 5 is provided with an inflow hole 22 that communicates with the upper water passage lid 21 and an outflow hole 23 that communicates with the bottom plate 13a,
The drug can be replenished in a clean state, and the amount of washing water that comes into contact with the drug can be restricted to prevent the drug from dissolving rapidly. Furthermore, the diverted washing water can dissolve the drug. By bypassing the inside of the container, the solution joins later than the washing water flowing down in the branch pipe 8, and the relatively high concentration solution flowing down at the end of washing is trapped in the trap 6.
The drug can be made to remain in the body and act effectively.
