Further, a nut 29 with a flange is also screwed onto the lower end of the screw shaft 25.

On the other hand, a liquid agent tank 30 is provided in the recess 17a of the frame 17.
is installed.

This tank 30 is formed into a cylindrical shape, and a predetermined amount of a liquid agent 30a having functions such as aroma, deodorization, and sterilization is filled inside.

A cap 32 is screwed onto the outlet 31 of the tank 30.

A through hole 32a is formed in the center of the bottom plate of the cap 32, and a valve stem 33 is slidably fitted into the through hole 32a.

Openings 32b, 32b are formed with the through hole 32a in between.

On the other hand, the upper end of the valve stem 33 has the opening 32b.

A disc-shaped valve 34 is fixed so as to close 32b.

Further, a pin 35 is fixed at right angles to the vicinity of the lower end of the valve stem 33, and a spring 3G is elastically mounted between the pin 35 and the lower surface of the cap 32.

Therefore, the valve 34 is always given a force in a direction to sandwich the opening 32b by the force of the spring 36.

Next, a method of using and operation of the liquid supply device according to the present invention configured as described above will be explained.

First, the folded portion 16a of the hanging plate 16 is hooked to the open end of the tank body 1 to suspend the frame 17 within the tank body.

In this state, with the cap 32 attached to the tank 30, the cap 32 is turned downward and the cap 32 is fitted into the recess 17a of the frame 17.

Then, the valve stem 33 is in a state of protruding into the frame 17.

However, unless force is applied to the valve stem 33, the spring 36
The force causes the valve 34 to remain closed.

At this time, if the water level in the tank body 1 is at a predetermined level, the float 28 has risen as shown in FIG. 18. It is rotated clockwise in FIG. 4 about 18, and the tip of the upper arm 19 is not in contact with the valve stem 33.

In this state, when you turn the operating lever 8 of the water washing tank, the arm 9
, the valve 12 opens via the chain 10 and the valve I h +
k+ 1 rh /I) → V h ~ RT H When it increases, the float 28 falls downward due to its own weight as shown in FIG. It is rotated counterclockwise around 18.

As a result, the tip of the upper 1119 comes into contact with the lower end of the valve rod 33, pushing up the valve rod 33 and the valve 34 against the force of the spring 36.

Then, the liquid agent 30a is supplied into the tank body 1 from around the valve 34 through the opening 32b and through the through hole 17b.

At this time, since the water in the tank body 1 is low, a certain amount of liquid is mixed at a high concentration into a small amount of water 1a.

When the water level drops further, the float 28
completely emerges from the water surface and its entire weight is applied to the rotating frame 23.

As a result, as shown in FIGS. 7 to 9, the tip of the upper arm 19 is elastic in the direction where the ribs 19b and 19b come into contact with each other at the thin part 19c between the ribs 19b and 19b*T.
'a l, - The disturbance that caused the ray 33 to become entangled will now be deviated from it.

Then, the weight of the liquid agent 30a is added, and the valve 34 side is lowered to close the opening 32b, thereby preventing the liquid agent from flowing out.

Through the above operations, a predetermined amount of liquid is supplied to the tank body 1 side.

Subsequently, when the discharge of water from the washing tank is stopped and the water level starts to rise, the rotating frame 23
is rotated clockwise and attempts to return to its original state, but in the middle of this, the tip of the arm 19 comes into contact with the side surface of the lower end of the valve stem 33.

At this time, the thin portion 19c between the ribs 19b, 19b is elastically deformed, rubs the side surface of the valve stem 33, and escapes toward the lower end of the valve stem 33.

At this time, the entire weight of the liquid agent is on the valve 34, so even if the tip of the arm 19 comes into contact with it, it will not be displaced.

The above operation is repeated to supply a predetermined amount of liquid into the tank body each time the washing tank is used.

As is clear from the above description, according to the present invention, there is provided a liquid supply device that can be attached to and detached from a washing tank with a single touch and that can supply a predetermined amount of liquid into the tank body each time the washing tank is used.

In addition, since the liquid is supplied when the water level in the tank is lowered and the water base is reduced, even a small amount of liquid can be mixed with water in a highly concentrated state, and when it is supplied to the toilet side, it can be used for fragrance and deodorization. , can fully demonstrate its sterilization function.
