BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chemical liquid ejector for a toilet to be placed on a hand washing / washing tank installed in the toilet.

[0002]

2. Description of the Related Art For example, a device disclosed in Japanese Utility Model Unexamined Publication No. 61-206777 is known as the above-mentioned toilet chemical liquid ejector. The medical solution discharger of the present invention includes a tray that is mounted on a lid plate on the upper surface of the tank and that expands the peripheral wall upward and outward from the outer periphery of the bottom wall with a drainage hole, and an outer peripheral portion that extends to the upper inner surface of the peripheral wall. A chemical liquid storage container placed with its lower surface in contact with it, and a valve rod inserted into a valve hole drilled in the center of the bottom wall of the container, and the lower surface of the valve body at the upper end of the valve rod is formed with a valve hole upper surface side peripheral edge. And a hanging float having an air-sealed portion attached to the lower end of the valve stem, the air-sealed portion having a convex shape in a side surface, the valve stem being erected from the center of the top surface, and the air being aired. A liquid storage cylinder is erected from the outer periphery of the upper surface of the enclosure, and an external air suction restriction cylinder that hangs down from the bottom wall of the container between the liquid storage cylinder and the outer surface of an upright cylinder part at the center of the air enclosure is filled with air at the lower end of the cylinder. It hangs down with a gap between it and the outer peripheral upper surface of the part.

In the above-mentioned conventional chemical liquid ejector, when hand washing water is poured into the upper surface of the container by draining water in the washing tank, the entire hand washing water is supplied to the upper end of the container peripheral wall and the receiving pan peripheral wall. , The float rises to open the valve hole, so that the drug solution in the container that has flowed out through the valve hole fills the liquid storage cylinder, and then enters the tray and enters the tray. It mixes with water and flows into the tank through the drain hole, and the float descends as the amount of water in the pan decreases, and the lower end of the outside air restriction cylinder separates from the liquid level in the liquid storage cylinder due to the decrease.
The outside air enters the container from between the lower end of the cylinder and the liquid level, and the chemical liquid enters the liquid storage cylinder by the replacement with the outside air, and the liquid level again closes the lower end surface of the outer air restriction cylinder, and the liquid enters the container. This was to prevent the inflow of outside air.

However, the above-mentioned conventional chemical liquid ejector has a complicated overall structure because the float is hung from the bottom of the container.
In addition, since the outer diameter of the upper end of the receiving wall of the receiving wall is larger than the outer diameter of the container, the entire water for hand washing poured into the upper surface of the container enters the receiving tray along the outer surface of the peripheral wall of the container, so that a large amount of water enters the receiving tray. The inflow causes the float to shake and the outflow of the drug solution to become unstable, and the receiving tray for receiving a large amount of water, and therefore the entire drug solution discharger, becomes large.

The present invention simplifies the construction of the components of the chemical solution discharger to facilitate transportation and assembly in a disassembled state, and makes the bottle body as a chemical solution storage container larger in diameter than the peripheral wall of the tray, and a part of the hand washing water. Of the float, and thus the height of the float, and thus the height of the chemical discharger, by placing the air-filled part of the float below the shoulder of the bottle placed on the tray in an inverted state. It is provided as possible.

[0006]

A closed container for accommodating a chemical solution is placed on a tray that rises from the outer periphery of the bottom wall with a drainage hole to the peripheral wall with a gap for entering water between the tray and the bottom plate. A valve stem is suspended from a valve body that closes the upper surface of a valve hole drilled at the center, a float having an air sealing portion attached to the lower end of the valve stem is suspended, and outside air that surrounds the valve hole from the sealed container and hangs down. In a toilet chemical liquid ejector in which a suction restricting cylinder is vertically suspended in an upper part of a liquid storage cylinder rising from the upper surface of the float, the closed container is connected to a shoulder 9 from an upper end of a body 8 having a diameter larger than a peripheral wall 6 of a receiving pan.
The bottle 11 that rises the mouth-and-neck portion 10 is formed upside down, and the valve hole is formed via the second inward flange 17 from the upper end of the outer tube 16 fitted on the inner surface of the mouth-and-neck portion. Support tube 13 hanging 18
The float 20 is formed by the inner cylinder hole, and the float 20 is further loosely inserted into the inner cylinder 18. A second outward flange 24 having a through-hole 23 is attached to the lower end of the upper surface closing cylinder 21 which is in close contact with the inner cylinder and which extends downward to the lower side of the inner cylinder.
It was formed by being attached below and attached.

[0007]

As shown in FIG. 1, when the water in the tank is discharged from the state in which the chemical liquid ejector is placed on the lid plate 30 of the washing tank, the faucet above the tank is simultaneously discharged into the tank.
From 31, hand washing water is discharged onto the chemical storage bottle 11. The water flows down along the outer surface of the body 8 of the bottle, and most of the water then falls onto the cover plate 30, but a part of the water enters the tray 1 having a smaller diameter than the body. Enter and float float 20. During the floating, the valve formed by the second inward flange 17 of the support cylinder 13 and the first outward flange 22 at the upper end of the upper surface closing cylinder 21 of the float opens, and the upper part of the upper surface closing cylinder 21 enters the bottle 11. Due to the high pressure in the bottle, the chemical liquid 32 in the bottle passes between the upper surface closing cylinder 21 of the float 20 and the inner cylinder 16 of the support cylinder 13 and between the inner cylinder and the liquid storage cylinder 26 of the float, and further. It mixes with the water in the pan 1 through the through holes 23 provided in the second outward flange. Further, as shown in FIG. 2, when the float rises to the upper limit, the outflow of the chemical solution is stopped by the cancellation of the high pressure state in the bottle. When the mixed water in the saucer 1 is reduced by passing through the drain hole 3 and further into the tank through the inlet hole of the tank cover plate 30, the float
20 falls. When the upper surface closing cylinder 21 is lowered by the float lowering, the pressure in the bottle becomes negative and the chemical solution in the liquid storage cylinder 26 is sucked up.
When the liquid level between the inner cylinder 18 and the lower end of the inner cylinder 18 falls below the lower end, the outside air flows into the bottle from the gap to eliminate the negative pressure state in the bottle, and the chemical liquid also flows down to re-enter the inner cylinder again. The lower end of the liquid surface of the bottle 18 is closed, and the inflow of outside air into the bottle is stopped. In this manner, as shown in FIG. 1, the first outward flange 22 at the upper end of the upper surface closing cylinder 21 is in close contact with the upper surface of the second inward flange 17 of the support cylinder 13 to close the inner cylinder hole as the valve hole.

And a bottle 11 to be placed on the tray in an inverted state, a support tube 13 fitted into the mouth and neck of the bottle, and a float 20 to be suspended from the support tube and stored in the tray. Therefore, by forming the support cylinder and the float as an integral member, it is easy to disassemble and assemble the respective members, and the bottle body 8 has a larger diameter than the peripheral wall 6 of the saucer. Since only a part of the hand washing water that falls on the bottom wall and flows down along the outer surface of the bottle body enters the saucer 1 and the other drops onto the lid plate 30 of the washing tank, the conventional hand washing water is used. Such a large amount of water suddenly enters the pan, so that the float does not shake and the chemical liquid in the bottle does not flow out more than necessary, and the air enclosing portion 25 of the float is placed below the bottle shoulder 9. Because it was located to
The height of the float 20, and thus the height of the entire liquid ejector, can be reduced.
