Description

The present invention relates to a fluid discharge device.

Conventionally, there is disclosed a soap dispenser 101 that is used by mixing a water soap solution and air to make the water soap into a mousse shape and discharging it, and fixing it to an installation table K such as a counter unit (for example, Patent Document). 1).

As shown in FIG. 7, the soap dispenser 101 disclosed in Patent Document 1 is inserted and fixed into a penetrating portion H formed in an installation table K which is a part of a counter portion of a hand wash basin. The soap dispenser 101 is configured separately from the mounting pipe 102 inserted and fixed in the penetrating portion H, the water soap liquid tank 103 connected and held under the mounting pipe 102, and the mounting pipe 102. A main body portion 104 that is detachably provided on the mounting pipe 102 is provided.

Most of the main body 104 is located above the installation base K in the soap dispenser 101, and the entire body 104 can be removed from the mounting pipe 102. The main body 104 is built in the body 105 and the body 105, and has the functions of a water soap liquid pump and an air pump. The water soap liquid is pumped and mixed with air to form a mousse. It is configured to include a mechanism unit 106 for delivering the water soap solution, and a discharge pipe 107 whose base end is fixed to the body 105.

A mesh 108 for promoting mixing of the water soap solution and air is fixed to the discharge pipe 107 in the vicinity of the base end thereof. In such a soap dispenser 101, the main body portion 104 is removed from the mounting pipe 102, and in this state, the water soap liquid is injected into the opening of the mounting pipe 102, so that the water soap liquid is supplied to the tank 103 via the mounting pipe 102. Be replenished. Further, the main body 104 and the tank 103 are connected by a ball chain 109 to prevent the main body 104 from being stolen or lost.

The covering wall 512 is formed with a communication hole 512A with the supply path main body 53. As a result, the replenishment port 511 can be enlarged, and the workability at the time of replenishment can be further improved.

Further, according to the above-described embodiment, by providing the air bleeding path portion 6, the air in the soap tank 21 escapes from the air bleeding path portion 6 when the soap liquid is replenished, so that it can be prevented from escaping from the replenishment path portion 5. ..

Further, according to the above-described embodiment, the supply path main body 53 and the air bleeding path main body 62 are arranged side by side and integrally formed. As a result, the number of parts can be reduced and the cost can be reduced.

Further, according to the above-described embodiment, the surrounding wall 10 can prevent the soap liquid from flowing into the air bleeding path portion 62.

According to the above-described embodiment, the air bleeding path portion 6 is provided, but the present invention is not limited to this. The air bleeding path portion 6 may not be provided.

Further, according to the above-described embodiment, the supply path main body 53, the air bleeding path main body 62, and the air bleeding path main body 62 are connected by a connecting wall 9 and are arranged side by side to be integrally formed, but the present invention is not limited to this.
