2 moves downward in the cylinder 431 and the ceiling 4
20 moves downward. As a result, the soap in the cylinder 431 passes through the tube from the liquid discharge pipe 436 and the spherical valve 1 of one of the pair of connection pipes 103 of the check valve 100.
02 is pushed up against the urging force and flows into the mixing chamber 104.

The air in the air chamber 441 passes through the tube from the air discharge pipe 418 and pushes up the other spherical valve 102 of the pair of connection pipes 103 of the check valve 100 against the urging force. After flowing into the mixing chamber 104, the soap in the mixing chamber 104 is foamed. The foamed soap is supplied from the nozzle 50 through the lower passage 271 to the upper passage 272 of the casing 20.

When the piston member 432 moves upward in the cylinder 431 due to the restoring force of the coil spring, the ceiling portion 420 also moves upward, and the pressure in the cylinder 431 becomes negative, so that the water soap in the tank body 31 becomes wet.

According to the water soap supply apparatus of the present invention, the casing is provided with the partition member for separating the supply passage and the air vent passage, so that the casing molding die does not mold the air vent passage. The molding die does not become complicated and the manufacturing cost can be reduced because the air vent passage is not molded.In addition, since the air vent passage is not molded, the draft of the air vent passage is reduced by the supply passage. Since it is not necessary to attach to the side, the casing does not have a large diameter, and it is possible to prevent an increase in the size of the device and an increase in the mounting space.

When the stopper member is mounted on the casing, the stopper member may be mounted on a predetermined position of the casing from a direction perpendicular to the cylinder axis direction of the casing. There is no need to screw together, and the stopper member can be easily assembled to the casing.
