In this attached state, the case body 21 containing the water soap is located under the wash basin B, and on the wash basin B, the nozzle flange 40 having the foam nozzle 150 mounted thereon and the cap 96 as a pressing operation portion. Etc. are only protruding,
Since no large mechanism or the like is installed on the washbasin B, the washbasin work is not hindered and the design is excellent.

Next, the check valve 111 for introducing outside air will be described. FIG. 13 is a cross-sectional view of the check valve 111 for introducing outside air. As shown in FIG. 13, the outside air introducing check valve 111 includes a valve case body 1 having a valve chamber 112a.
It has twelve. An introduction passage 112b and an outflow passage 112c connected to the valve chamber 112a are formed at both ends of the valve case body 112. A seat member 112e having a conical seat surface 112d is fixed to the valve case body 112 on the introduction passage 112b side.

A valve body 113 is arranged in the valve chamber 112a. The valve body 113 includes a valve body head portion 113b having a hemisphere seating surface 113a, and a valve body guide portion 113c integrally assembled with the valve body head portion 113b. A guide portion communication hole 113d is formed in the valve body guide portion 113c. Further, the valve body 113 and the valve case body 11
The coil spring 114 is provided between the second case inner wall 112f and the case inner wall 112f.
Has been erected.

The introduction passage 112b is connected to the outside air introduction port 110b through the outside air introduction passage 110 formed in the bottom lid 50.
It is connected to the. In the outside air introduction passage 110 of the bottom lid 50, a valve body support portion 115b having a supporting through hole 115a.
The valve body return pin 115 is slidably supported in the supporting through hole 115a.

The check valve 111 for introducing the outside air is provided in the outflow passage 112c when the bellows 70 for supplying air is expanded.
The side becomes negative pressure, the pressure in the valve chamber 112a decreases, and the atmospheric pressure in the introduction passage 112b changes to the coil spring 114 and the valve chamber 11.
When the pressure in 2a is exceeded, the valve body 113 opens. As a result, air is introduced into the air supply bellows 70 through the introduction passage 112b, the valve chamber 112a, and the outflow passage 112c, and further through the outside air introduction passage 110.

Next, the returning operation when the valve body 113 is fixed to the seat member 112e will be described. The foamy soap is discharged from the foam nozzle 150 when the water soap pressure-fed through the water soap outflow passage 140 is bubbled by the air in the air outflow passage 120. Then, when the air supply bellows 70 returns from the compressed state to the original state, outside air is introduced through the outside air introduction check valve 111, but is not discharged from the bubble nozzle 150 and remains in the nozzle passage 150a or the like. The foamy soap that is flowing also flows back due to its suction force.

The air outflow check valve 121 blocks the foamy soap flowing back, but is slightly backflowed by repeated use. When the mousse dispenser 10 is not used for a long period of time, the foamed soap flowing back flows in the air outflow check valve 121 or the outside air introduction check valve 111 by fixing the valve body 113 to the seat surface 112d to open or close the seat. It may be a hindrance. However, the air outflow check valve 121 is easy to open because it receives the pressure of the air sent from the air supply bellows 70. In particular, the outside air introduction check valve 111 uses the suction force of the air supply bellows 70. Since the valve is opened, a large valve opening force is not obtained, and the valve body 113 is not exposed to a liquid like the water soap introducing bellows 131 and is dried by air so that the valve body 113 is fixed to the seat member 112e and opened. May not speak.

In such a case, by pushing the valve body operation return pin 115 protruding from the bottom cover 50, the valve body 113 is forcibly separated from the state in which it is fixed to the seat member 112e, and the outside air introducing check valve 111 is released. It is possible to eliminate the state where the opening / closing operation is not performed.

FIG. 14 shows a check valve 11 according to another embodiment.
1B, the valve operation return pin 115B is supported by the end of the introduction passage 112b of the valve case main body 112 and held in contact with the valve head 113b.
According to this check valve 111B, it can be used as an air outflow check valve 121 other than the outside air check valve 111.

[0064]

As described above, according to the mousse dispenser of the present invention, the check valve provided in the air passage is provided with the movable means for opening the valve by the forced force from the outside, so that the air supply means can be operated negatively. It is possible to recover the opening / closing operation of the check valve, which is operated by pressure and has a small opening / closing force, which makes it difficult to open / close.
