An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, 10 is a deodorizing liquid container made of a transparent bottle, and an airtight cap 12 is attached to the upper end.
is removably attached, and a cylindrical protrusion 14 having a male thread is provided at the lower end, and an outlet 18 from which a deodorizing liquid 16 can be drawn out is formed inside the cylindrical protrusion 14 .

The container 10 is coupled to the storage tank 20 by screwing the cylindrical protrusion 14 into the internal thread of the recess 22 formed in the upper center of the storage tank 20 . The storage tank 20 has a hollow cylindrical shell 24 whose upper end is closed, and a bottom lid 26 that is attached to a gasket 2 at the open end side of the lower end.
8 and are screwed together. The upper end of the shell 24 is formed integrally with the side wall of the shell 24, and the recess 22 is formed in the center thereof as described above, and the container 10 is attached with the packing 30 sandwiched therebetween.

In this way, a space is formed inside the storage tank 20 in which the deodorizing liquid agent 16 and the air can be sealed. A cylindrical protrusion 32 serving as a lead-out portion having a smaller diameter than the recess 22 is provided on the outer side of the shell 24 below the recess 22.
is formed in a stepped shape, and its lower end is connected to the bottom cover 26.
is closely followed. The outlet 18 of the container 10 allows the deodorizing liquid 16 to reach the bottom of the static liquid level 36 in the storage tank 20 through a hollow part 33 in the cylindrical protrusion 32 and a notch 34 provided at the lower end of the cylindrical protrusion 32. It is connected to and can be opened. Furthermore, Ciel 2
4. A cylindrical protrusion 38 is formed at the upper position of the outer circumference,
An air valve body 42 having a tapered tip and a small hole 40 is screwed into the cylindrical protrusion 38, as shown in FIGS. 1 and 3. In this way, the air valve is constructed. This allows communication between the inside of the storage tank 20 and the outside air, and by adjusting the rotation of the air valve body 42, the storage tank 20
0 Communication between the inside and the outside air can be adjusted.

A cylindrical protrusion 44 is provided below the outer circumference of the shell 24, and the cylindrical protrusion 44 has a communication hole 46 in the center.
A flow pipe 50 is connected to the other end of the flow pipe 50, and the other end of the flow pipe 50 is connected to the downstream side of a water discharge valve 54 of a water pipe 52 that can flow water for flushing to the toilet bowl. are joined, and the inside of the storage tank 20 and the water pipe 5
2 can communicate with each other. In this way, a communication channel that communicates between the storage tank 20 and the water pipe 50 is formed. The end of the communication hole 46 of the joint 48 is positioned below the static liquid level 36, and the intermediate part of the flow tube 50 is positioned below the static liquid level 36.
It is set to be higher than 6.

The outside of the container 10 and the storage tank 20 is an outer case 5.
6 and a case cover 58. In this way, the deodorizing liquid supply device 60 is configured. FIG. 4 shows the above embodiment as a urinal 6.
2 shows the installed state. Of course, it is possible to use it by attaching it to a toilet bowl.

Next, the operation of the previous embodiment will be explained. first,
Before starting to use the deodorizing liquid 16 in the storage tank 20.
is not stored. In such a situation,
When the container 10 filled with the deodorizing liquid 16 is attached to the storage tank 20, air enters the container 10 through the notch 34, and the deodorizing liquid 16 in the container 10 flows into the notch 34.
The water flows out through the tank and is stored in the storage tank 20. As the deodorizing liquid agent 16 is stored, the liquid level gradually rises, and when it reaches the vicinity of the upper end of the notch 34, the container 10
Since the supply of air into the container 10 is cut off and a negative pressure is generated in the inner space of the container 10, the deodorizing liquid in the container 10 cannot flow downward. Therefore, the liquid level height of the deodorizing liquid in the storage tank 20 is constant and becomes the static liquid level 36. In this case, one end of the flow pipe 50 connected to the water pipe 52 is below the static liquid level 36, but the middle part of the flow pipe 50 is higher than the static liquid level 36, so that the deodorizing liquid 16 naturally flows. It will not leak out.

When the water discharge valve 54 is opened when the toilet is used, high pressure water in the water pipe 52 flows out, and the dynamic pressure in the water pipe 52 increases. According to Bernoulli's theorem, dynamic pressure + stationary pressure = constant, so the static pressure decreases by the amount that the dynamic pressure increases, and the deodorizing liquid in the flow pipe 50 is sucked, mixes with the water in the water pipe 52, and flows into the toilet bowl 62. is washed with water. However, when the liquid level of the deodorizing liquid in the storage tank 20 decreases and the flow hole 46 of the joint 48 is exposed to the air, air is sucked into the water pipe 5 of the deodorizing liquid.
Supply within 2 will be discontinued. When the liquid level of the deodorizing liquid drops below the static liquid level 36, the deodorizing liquid in the container 10 is supplied into the storage tank 20 through the notch 34 and stored therein, but in this embodiment, it is discharged through the flow tube 50. Since the flow rate is made larger than the falling flow rate supplied through the notch 34, the deodorizing liquid agent stored in the storage tank 20 is mixed with the flowing water in the water pipe. That is, a certain amount of the deodorizing liquid agent is supplied into flowing water and mixed. The speed at which the air is supplied falling into the storage tank 20 through the notch is determined by the size of the notch and the opening degree of the valve body 42 of the air valve, so by adjusting the opening degree of the valve body 42. Therefore, it is possible to adjust the falling supply speed.

As described above, according to this embodiment, a predetermined amount of the deodorizing liquid can be mixed into running water (spouted water) and released each time it is used, so it is highly effective in removing bad odors from the toilet bowl and inside the toilet. Further, since the deodorizing liquid is contained in the deodorizing liquid container 10 or the storage tank 20, the deodorizing liquid is not wasted constantly due to volatilization, evaporation, etc. Furthermore, it is possible to prevent the chemical odor of the deodorizing liquid from constantly lingering.

In the embodiment described above, instead of the cylindrical protrusion 32 serving as the lead-out portion, the cylindrical protrusion 14 of the container 10 may be extended and integrated. That is, the extended lower end of the cylindrical protrusion 14 is immersed in the deodorizing liquid in the storage tank 20, and a cutout 34 for supplying air is provided near the lower end. Also,
Instead of the sealed storage tank 20, it may be open, and the opening area of the portion that supplies air into the container 10 may be changed.

Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment in any way, and it goes without saying that it can be implemented in various forms without departing from the gist of the present invention. It is.

[Effect of idea]

As detailed above, according to the present invention, a predetermined amount of the deodorizing liquid in the storage tank supplied from the deodorizing liquid container can be mixed with the flowing water in the water pipe for passing water to the toilet bowl. As a result, it is possible to accurately remove bad odors when the urinal is used, and the deodorizing liquid is not wasted at times other than when it is used.
