BACKGROUND OF THE INVENTION The present invention relates to a liquid detergent and a pressurized air, for example, which supplies a liquid detergent with the pressure air to form a mousse (foam) and discharges the liquid detergent from a nozzle. It is about structure.

[0002]

2. Description of the Related Art For example, a drive-in where a lot of people come and go,
In hotel, restaurant, theater and other hand washing places,
Detergent equipment is required to improve hygiene.

[0003] Generally, a detergent container for containing a liquid detergent is provided near each wash basin, and a person washing his / her hands uses an appropriate amount of detergent by pouring out from the detergent container. is there.

However, since the detergent contained in the above-mentioned detergent container is a liquid, the detergent poured into the palm of the detergent from the container hangs down between fingers, or more detergent than necessary is poured out. As a result, detergent was apt to be wasted, and especially in public hand washing places, the amount of waste was large and the economic efficiency was poor. In order to increase the liquid detergent, development of a mousse-like detergent supply device capable of discharging a liquid detergent in the form of a mousse (foam) has been promoted. This mousse-like detergent supply device is, for example, as shown in FIG. 1, and its structure and operation will be described below. 1 is a liquid detergent 2
The container 1 is provided with a detergent inlet 3, a detergent pressure outlet 4, a pressure inlet 5 into which pressurized air is injected into the container 1, and a discharge port 6. Reference numeral 7 denotes a hermetic lid which is hermetically attached to the inlet 3.

[0005] Reference numeral 8 denotes a compressor. A pipe 9 for supplying pressurized air into the vessel 1 and a pipe 11 branched from the pipe 9 and for supplying pressure air to a nozzle 10 are connected to the compressor 8. Have been. 12, a compressor control circuit for controlling the compressor 8;
Is opened and closed by the operation of a switch 14, and is a solenoid valve interposed in the middle of the pipe 11, and 15 detects the internal pressure in the container 1, and outputs the detected information to the compressor control circuit 1.
Reference numeral 16 denotes a pressure sensor to be input to 2, and 16 denotes a liquid pressure feed pipe communicating between the pressure outlet 4 and the nozzle 10.

The operation of the prior art has been described above. Next, the operation will be described. Next, an appropriate liquid detergent is put in the container 1 and hermetically sealed. Then, the compressor 8 is driven to bring the inside of the container 1 to a desired pressure. Keep it. When the switch 14 is operated to open the solenoid valve 13, pressurized air from the compressor 8 is applied to the nozzle 10 via the pipe 8, and simultaneously, the liquid detergent 2 pressed by the pressurized air is applied to the nozzle 1 via the liquid pumping pipe 16.
Since the liquid detergent 2 is pressure-fed, the liquid detergent 2 is discharged from the nozzle 10 in the form of a foam (mousse) together with the pressurized air.

[0007]

However, in the container 1 having such a structure, when a liquid detergent is injected from the detergent inlet 3 of the container 1, a large amount of bubbles are generated in the container 1. However, the foam is not mixed with the liquid in the container and is extruded from the nozzle 10, so that the foam cannot be smoothly discharged (discharged). Further, the bubble action in the container causes problems such as difficulty in properly detecting the liquid amount and the atmospheric pressure in the container.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem. An anti-foaming tube is erected between the upper and lower sides of a container for containing a liquid detergent, and the lower end of the anti-foaming tube is provided at the lower end of the anti-foaming tube. In addition to forming a communication hole that communicates the inside and outside of the anti-foaming cylinder, a pressure sensor and an exhaust port are provided inside the upper end of the anti-foaming cylinder, and the reliability of the detection of the liquid amount and the atmospheric pressure in the container is improved. It is an object of the present invention to provide a bubble prevention structure in a liquid pressure tank capable of discharging good bubbles by a nozzle.
