DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on the embodiments shown in the drawings.

In FIG. 2, 11 is a water pipe that is generally piped, and a faucet 12 and a pressurizer 13 are branched and connected to the water pipe 11. This pressurizer 1
The internal structure of 3 is as shown in FIG. 3 and FIG.
Is a casing thereof, and a water pressure supply port 15 is integrally formed in the casing 14, and a connection cap 18 having an intake port 16 and an exhaust pressure port 17 is airtightly screwed through an O-ring 19. .. A piston 20 is slidably fitted in the casing 14, but the piston 20 is pushed toward the water pressure supply port 15 by the elastic force of a spring 21.

Further, a step portion 22 is formed in the casing 14 by the connection cap 18, and the piston 20 is configured to be stopped midway in the casing 14 by this step portion.

Returning to FIG. 2, reference numeral 23 is a tank containing soapy water 24 therein, to which a connecting pipe 25 leading to the exhaust port 17 of the pressurizer 13 is connected. Reference numeral 26 is a nozzle device.
The air supply pipe 28 leading to the above is connected, and the foaming soap is discharged from the nozzle 30 by operating the operation knob 29. Reference numeral 31 is a one-way valve provided in the intake port 16.

The structure of this embodiment has been described above. Next, its operation will be described. As shown in FIG. 2, the pressurizer 13 is connected to the water pipe 11, and the tank 23 and the nozzle device 26 are connected to the pressurizer 13. To do.

Then, by closing the faucet 12, the water pressure in the water pipe 11 acts on the piston 20, and the piston 20 is pushed down against the elastic force of the spring 21, as shown in FIG. The air in 14 is compressed. The compressed air acts on the inside of the tank 23 and the inside of the nozzle device 26. Therefore, by pushing the operation knob 29, the foamed soap is discharged from the nozzle 30.

Since tap water is used, when the faucet 12 is opened, the water pressure in the water pipe 11 drops, so that the piston 20 of the pressurizer 13 rises due to the elastic force of the spring 21, as shown in FIG. By closing the faucet 12 again, the water pressure in the water pipe 11 acts on the piston 20 and the air in the casing 14 is compressed, so that the foaming soap is ready to be discharged from the nozzle device 26.

In this way, each time the tap is opened and closed, the piston 20 in the pressurizer 13 moves up and down to send pressurized air to the soap water tank 23 and the nozzle device 26, so that electric power is used. The foamed soap can be ejected from the nozzle 30 without using.

FIG. 5 shows another embodiment of the pressurizer. This pressurizer 13 'has a piston chamber 33 and a pressure air chamber 3 formed by a valve seat 32 at a substantially central portion inside the casing 14.
4, a piston chamber 33 is provided with a water pressure supply port 15 and a piston 20 pushed up by a spring 21, and a pressure air chamber 34 is provided with an exhaust pressure port 17. Further, the valve seat 32 has an outside air intake passage 36 in which a one-way ball valve 35 communicating with the outside air is installed,
A pressure receiving plate 37 is provided on the piston chamber 33 side, and a pressure air chamber 34 is provided.
A communication hole 40 penetrating an operating rod 39 having a valve 38 on the side is provided. The operating rod 39 is urged by the action of the spring 41 so that the pressure receiving plate 37 is projected toward the piston chamber 33 side and the communication hole 40 is closed by the valve 38.

Therefore, according to the pressurizer 13 'of this embodiment, when the water pressure is applied from the water pressure supply port 15, the piston 20
Is pushed down against the elastic force of the spring 21, and as a result, the atmospheric pressure in the piston chamber 33 rises, and the atmospheric pressure pushes the valve 38 downward against the elastic force of the spring 41 to open the communication hole 40. The pressure air in the piston chamber 33 is introduced into the pressure air chamber 34. The pressure air in the pressure air chamber 34 is pressure-fed to the soap water tank 23 through the pressure exhaust port 17.

Therefore, according to the pressurizer structure of this embodiment,
Since the pressure air chamber 34 that can be maintained at a predetermined air pressure is configured, the pressure in the tank can be stably maintained, and the piston chamber 33 and the pressurizer 13 ′ that configures the pressure air chamber 34 can be made simple and easy. Can be configured to.

FIGS. 6 and 7 show a pressurizer structure showing still another embodiment of the present invention. This pressurizer 13 ″ has an intake port 16 having a one-way valve 31 as in the case of the above embodiments. Inside the casing 14 having the exhaust pressure port 17 and the water pressure supply port 15, a piston mechanism 42 that operates by the water pressure supplied from the water pressure supply port 15 is installed. The piston mechanism 42 that operates by the water pressure is provided with a stopper mechanism for stopping the pressure air chamber 34 shown in Fig. 7 by stopping at a substantially intermediate portion inside the casing 14. That is, this piston mechanism is provided. 42 is a piston main body 43, and a spring 44 is provided at the center of the piston main body 43.
The guide member 45 is pushed downward by the elastic force of the guide member 45 and the taper surface 47 corresponding to the taper surface 46 provided on the guide member 45.
7 have respective locking members 48 that move in the direction orthogonal to the axial direction of the casing 14 by abutting of 7, and springs 49 that move and bias the locking members 48 in the central axis direction of the piston body 43. There is.

A locking groove 5 for locking the locking member 48 is formed at a substantially central portion in the vertical direction on the inner peripheral surface of the casing 14.
0 is formed. Reference numeral 51 denotes a spring for pushing up the piston mechanism 42.

In the pressurizer 13 "having such a structure, when the water pressure is now supplied from the water pressure supply port 15, the piston mechanism 42 pushes down against the elastic force of the spring 51, as shown in FIG. As a result, the air in the pressure air chamber 34 is pressurized, and when the piston mechanism 42 is pushed down to a substantially middle portion of the casing 14, the pressure air chamber 34 is pressed.
Since the inner pressure is received by the lower surface of the guide member 45, the guide member 45 is pushed up against the elastic force of the spring 44. The protrusion end of the locking member 48 is locked in the locking groove 50 as a result, and the volume of the pressure air chamber 34 can be secured.

The pressure air thus increased in the pressure air chamber 34 is applied to the inside of the tank through the exhaust pressure outlet 17.
By ejecting bubbles from the nozzle 30, the pressure air chamber 34
When the air pressure in the inside is gradually reduced, the locking member 48 is lowered by the elastic force of the spring 44, and as a result, both locking members 48 are restored by the elastic force of the spring 49, so that the locking member 48 is engaged. Since the locking force with the stop groove 50 is released, the piston mechanism 42 rises due to the elastic force of the spring 51.

When water pressure again acts from the water pressure supply port 15, the piston mechanism 42 descends again and the air pressure chamber 3
The air pressure in 4 can be increased.

Therefore, according to this embodiment, the pressure air chamber 34
Therefore, the pressure inside the tank 23 can be stably maintained, and the generation and discharge of bubbles can be smoothed.
