The discharge nozzle 2 is installed on a counter surface provided in a washroom or a toilet, or on any other installation surface C, and the tank 1, the liquid supply means 4a, and the pressurizing device 6 are placed below the installation surface C or other appropriate surface. Located at the location.

[0007] Tank 1 is a pressure-resistant tank equipped with a top wall or an appropriate position in the closable supply opening in the side wall (not shown), a supply port 1a of the compressed air in its upper portion, the bottom portion of water
An outlet 1b for soap a is opened respectively. The supply port 1a communicates with the liquid supply means 4a via an air pipe 4 '. A pressure sensor b is provided inside the tank 1, and the pressure sensor b electrically communicates with the control unit 7. The pressure sensor b comprises a pressure switch using a well-known strain gauge or a magnetoresistive element, and transmits the pressure in the tank 1 to the control unit 7 as an electric signal using a change in electric resistance accompanying a change in the pressure in the tank 1. I do.

The discharge nozzle 2 has an inlet 2a for water soap a and an air inlet 2b at the bottom and a discharge port 2c at the tip, and the two inlets 2a and 2b and the discharge port 2c inside. Is provided. Further, as shown in FIG. 2, with the intermediate portion of the flow path 2d is provided an opening and closing valve 8, the discharge port within 2c by mounting a plurality of mesh member 9, water soap a
Then, a stirring chamber 10 for stirring the air is formed.

[0009] The water soap inlet 2a is connected to the outlet 1b of the tank 1 by a pipe 3 ', thereby forming a water soap supply path 3 which connects the tank 1 and the discharge port 2c. The pipe 3 ′ is branched into a plurality of parts in the middle part, and the discharge nozzle 2 is connected to each of the branched ends.

The open / close valve 8 can be operated by pressing a push button, even if it is an electric or electromagnetic type that opens for a certain period of time by an electric signal based on a hand detection by a human sensor such as a photoelectric sensor or a pressing operation of a touch switch. A manually operated valve that opens mechanically while the button is being pressed (or for a certain period of time) may be used, but in the illustrated example, a manual open / close valve is operated by operating the push button 8a.

[0011] liquid supply means 4a, the water in the tank 1 by sending compressed air into the tank 1 through the air pipe 4 '
A pressure device for feeding the soap a to the discharge nozzle 2, for example, a compressor, a hydraulic (hydraulic) cylinder, a pressure cylinder or the like is electrically connected to the control unit 7.

The pressurizing device 6 is a device for forcibly sending air to the discharge port 2c through the air supply path 5, for example, a compressor, a hydraulic (hydraulic) cylinder, a pressurized cylinder, etc., and is electrically connected to the control unit 7. doing. The air supply path 5 is formed by connecting the pressurizing device 6 and the air inlet 2b with a pipe 5 '.
The pipe 5 'is branched into a plurality of parts in the middle part, and the discharge nozzle 2 is connected to each of the branched ends. An air tank 11 and a safety valve 12 are provided at appropriate positions in the pipe 5 '.
You. A check valve 13 is connected to the pipes 3 ′ and 5 ′,
Provide upstream. The pressure sensor b is provided in the air tank 11.

The control unit 7 receives the detection signal from the pressure sensor b and generates an output when the internal pressure of the tank 1 and the air tank 11 becomes lower than a predetermined pressure, and disappears when the pressure becomes higher than the predetermined pressure. The liquid supply means 4a and the pressurizing device 6 are activated upon receiving the above output to supply compressed air into the tank 1 and the air tank 11, and to supply the compressed air to the tank 1 and the air tank 11 in a predetermined manner. Pressurize to pressure. still,
When the liquid supply means 4a is constituted by a pressurized cylinder, an electric valve is provided in the middle of the air pipe 4 ', and the operation of the electric valve is controlled by the control unit 7, so that the inside of the tank 1 is maintained at a predetermined pressure as described above. Press. The control unit 7 is provided on the installation surface C as shown in the figure, or provided near the tank 1 and the liquid supply means 4a.

According to the above configuration, the operation of the liquid supply means 4a is controlled by the control unit 7 to constantly pressurize the inside of the tank 1 to a predetermined pressure. Water soap a in the tank 1 is pressure-fed to the flow path 2d of the discharge nozzle 2 by pressurization, and is discharged from the discharge port 2c by pressing the push button 8a. At the same time, the air supplied from the pressurizing device 6 and the water soap a are mixed in the flow path 2 d and are stirred by the net 9 in the stirring chamber 10. Therefore, the water soap a is discharged in a bubble state.

Discharging the water soap a in the form of a foam as described above not only prevents the water soap a from being discharged due to the internal pressure of the tank 1 being too strong, and prevents the water soap a from splashing or falling. In addition, a small amount of water soap a can be used efficiently, which is effective in saving water soap a. In addition, respective pipes 3 on the water soap supply side and the air supply side
The check valve 13 is provided at the 5 'and 5'
To remove the tank 1 for maintenance
When the discharge nozzle 2 is removed, the water stone in the discharge nozzle 2
Prevents the flow of backwater or air into pipes 3 'and 5'.
Can be

In FIG. 3, small diameter portions 2c 'are provided at appropriate intervals in the discharge port 2c in place of the above-mentioned net 9, thereby forming the stirring chamber 10.

FIG. 4 is a sectional view of the first embodiment of the present invention .
Although not shown, there is shown a reference example in which the above-mentioned liquid supply means is constituted by a sending device, for example, a liquid sending pump 4b. That is, in this example , an open type tank is used for the tank 1 ', and a liquid feed pump is provided in the middle of the pipe 3' connecting the outlet 1b of the tank 1 'and the discharge nozzle 2'. 4b is provided. Further, the liquid feed pump 4b, the switch 14 provided on the discharge nozzle 2 ', and the electric valve 15 provided on the pipe 5' are connected to the control unit 7.
To make electrical contact. Then, by operating the switch 14, the liquid feed pump 4b and the electric valve 15 are operated.
The water soap a and the air are sent to the discharge nozzle 2 'to discharge the foamed water soap from the discharge port 2c in the same manner as described above.

In this example , the liquid feed pump 4b
Since the motor-operated valve 15 acts as an on-off valve, there is no need to provide the on-off valve 8 in the flow path 2d of the discharge nozzle 2 'as shown in FIGS. Further, the liquid feed pump 4b is not limited to the electric type, and may be a manual type.

In the present invention, the water soap a is not limited to hand soap, but is not limited to shampoos, rinses, cosmetics, detergents used for various purposes, and other household and business uses. Can be arbitrarily selected according to the purpose of use.

In the above embodiment , the pipes 3 ', 5
Or providing such a flow rate adjusting valve in the middle part of the 'or liquid supply means, and adjustable output pressure device, thereby water
Soap and air supply can be adjusted arbitrarily,
The shape (fineness) of the foamed water soap can be adjusted according to the user's preference. Furthermore, desired functions other than those described above, for example,
Function to display the remaining amount of water soap a, warning function for preventing an overflow from the tank 1 during replenishment of water soap a, tank 1 and discharge nozzle 2,2'-pipe 3 ', 5'
It is of course optional to add a function or the like for displaying an abnormality when there is leakage of water soap a or air due to damage such as damage.
