The other end of 9 is fitted into the upper end of overflow pipe 11 .

Further, one end of a long L-shaped pipe 50 is connected to the other cylindrical body 46, and the other end of the pipe 50 is guided downward along the cylinder 17.

Next, the operation of this embodiment configured as above will be explained.

When the washing tank is not in use, the water level of water 7 is at a constant level, the float 21 is rising, and the fifth
As shown in the figure, the valve 25 is also rising via the rod 24, and the head 24a of the rod 24 is pushing the lower end of the valve stem 39, so the spring receiver 41 is rising against the force of the spring 40. A sealing material 43 contacts the lower end of the cylinder 36 and blocks communication between the connecting cylinder 34 and the cylinder 17 side.

In this state, the valve 38 is raised, and the liquid agent 32a in the container 32, which plays a role of aroma, deodorization, sterilization, etc., is supplied to the temporary storage part 36a of the cylinder 36, which is sealed by the sealing material 43, through the small hole 37a. However, it is not supplied into the cylinder 17.

On the other hand, when the lever 8 is turned to drain water, the water level in the tank is lowered, and the float 21 and valve 25 are lowered.

The inside of the fruit cylinder 17 becomes negative pressure, and the valve 48a opens inward, /hX.

At this time, the spring receiver 41 is also lowered by the force of the spring 400, as shown in FIG.
a is circle i! 17 and valve 38 is also closed.

As a result, in the space above the valve 25, the water 7 in the tank 71 sucked through the vibrator 50 by negative pressure and the liquid agent 32a are mixed.

At this time, the support frame 22 is attached to the ring 2 at the lower end of the slit 19.
0, the valve 25 is located above the upper end of the slit 19, and water mixed with the liquid agent 32a does not escape from the slit 19.

Further, when the upper end of the cylinder 17 is under negative pressure, the other valve 47a is closed and no liquid is discharged from there.

On the other hand, water supplied through the water injection pipe 3 is supplied into the tank 1, and when the water level rises, the float 21 also rises, and the valve 25 also begins to rise as shown in FIG. is pushed up. At this time, the valve 48a is closed and the valve 47a is opened, allowing water mixed with the liquid agent to be supplied into the overflow pipe 11 via the vibrator 49.

Since the overflow pipe 11 is always in communication with the drain pipe 12 regardless of whether the valve body 13 is open or closed, when the water 1 in the washing tank is drained and the float 21 starts to rise, the water mixed with the liquid agent 32a will be discharged. It mixes with the water that is supplied into the toilet bowl and remains on the toilet bowl side, emitting a fragrance and also has a deodorizing effect. If a sterilizing agent is used as the liquid 32a, it will exhibit a sterilizing effect within the toilet bowl, and if another liquid is used, it will exhibit the unique effects of that liquid.

When the float 21 reaches its upper limit, it enters the initial state shown in FIG. 5, the lower end of the cylinder 3G is closed by the sealing material 43, the valve 38 rises, and a certain amount of the liquid 32a enters the space inside the cylinder 36. Supplied.

By repeating the above operations, the liquid containing the fragrance and deodorizer is discharged each time the flush tank is used.

As is clear from the above description, according to the present invention, a structure is adopted in which the existing water washing tank can be removed extremely easily via the clamping part, and depending on the water level in the tank, i.e. A fixed amount of liquid can be discharged each time the flush tank is used.

In addition, the chemicals are not diffused into the water in the flush tank, but are supplied to the toilet side through the overflow pipe and remain there, so that aroma diffusion, deodorizing effects, and sterilizing effects can be reliably maintained. Therefore, in order to maintain the fragrance, deodorization, and cleanliness of the toilet, air fresheners, deodorants, and
By using the same rigidity as the disinfectant, the effectiveness of this device can be fully demonstrated.
