A plurality of holes are formed, and are integrally formed or disposed with an adhesive at substantially the center in the container body 1a.
8 is notified.

The smaller the number of the communication holes 5b provided in the partition wall 5, the less the influence on the adjacent room can be reduced. However, since the speed of intrusion into the adjacent room becomes slow, it takes time to replenish. In consideration of this point, it is necessary to determine the number and position of the communication holes 5b, the total area of the communication holes 5b, and the like.

In the figure, reference numeral 15 denotes a drain port formed on the bottom surface 1b for cleaning precipitates.
Are provided radially, and the ribs 16 serve as guides for discharging (replacement) of the soap, so that smooth discharge can be expected.

When the ribs 16 are provided, the bottom surface 1b of the container body 1a is inclined downward toward the drain port 15. The water soap supply port 9 protrudes cylindrically from the inclined surface 7b of the container body 1 to a desired length, and the supply port 9 is closed by a desired supply lid 24.

The replenishing lid 24 has an insertion cylindrical portion 24a which is in close contact with the inner wall surface of the replenishing port 9, and an upper surface 24b of the cylindrical portion 24a.
A flange 24c is extended from the outer peripheral edge of the upper surface 24b, and a horizontally long handle 24d is bulged at a substantially central portion of the upper surface 24b.

The rear surface 25b is provided with a system switch 19 of the pressurizing device 4 linked to a control unit 17 described later, and is linked with opening and closing of the lid cover 25.

Therefore, the fitting portion 26 is provided with the supply lid 24 in the supply port 9.
Is recessed to a depth and a shape that match the height and shape when completely closed, so that if the supply lid 24 is not completely closed to the supply The system switch 19 is not turned ON because the portion 26 does not match the handle 24d of the replenishing lid 24 and does not close the lid cover 25.

That is, if the lid cover 25 can be completely closed, it can be confirmed that the supply lid 24 is sealed. In addition, supply lid
The outer surface 24e has a protruding portion even if its outer surface 24e has a shape other than a plane circular shape, or a flat circular shape, and is not limited to a special shape as long as the cover cover 25 is fitted, and is arbitrary.

In the drawing, a hinge 27 is provided above the lid cover 25.
Although not shown, the fixing means of the lid cover 25 is not shown in the figure, but it is also possible to fix the lid cover 25 by using known means as appropriate. In such a case, it is optional to insert a seal member on the contact surface with the tank 1 and fix the seal member to provide airtightness.

In the illustrated example, the replenishing lid 24 is fitted into the replenishing port 9 and sealed while being pressed from above by the lid cover 25. It may be something.

If the replenishing lid 24 is of the screw type as described above, the lid cover 25 may be simply covered. The system switch 19 to be described above is a conventionally known switch such as a microswitch. When the lid cover 25 is closed, the pressure becomes 0N and the pressurizing device 4 is driven. I do.

FIGS. 3 to 5 show a supply lid 2 according to another embodiment.
4 'and lid cover 25' are shown. According to the illustrated example, the supply lid 24 ′
As shown in FIGS. 3 and 4, the insertion cylinder portion is similar to the supply lid 24.
A flange portion 24'c is extended from an outer peripheral lid portion of an upper surface 24'b of 24'a, and has a plan shape in which left and right circular ends are cut into a bow shape as shown in FIG. A fitting portion 26 'is formed in the lid cover 25' so as to have a shape matching the supply lid 24 '(see FIGS. 3 to 5).

Therefore, unless the linear portions 28, 28 of the replenishing lid 24 'and the linear portions 28, 28 of the lid cover 25' match, the lid cover
25 'is not closed, and the system switch 19 is not turned on. The other configuration, operation and effect are the same as those shown in FIGS. 1 and 2, and the description thereof will be omitted.

The pressurizing device 4 comprises a desired compressor 4a and the like, and an air supply pipe 4b interposed between the compressor 4a and the air supply pipe mounting port 1d of the pressure vessel 1. Air is supplied to the air reservoir 10 of the container 1 to pressurize the inside of the container 1. By utilizing the pressurizing action, the soap is sent to the discharge nozzle 6 and the compressed air is sent to the discharge nozzle 6 via the air output pipe 3.

In the figure, reference numeral 20 designates an electromagnetic valve (three-way valve or the like) provided in the middle of the air supply pipe 4b and linked to the control unit 17 to supply water soap (at the start of driving of the compressor 4a) or the pressure vessel 1 The solenoid valve 20 is driven for a very short time (for example, 0.1 second) as necessary, such as during over-pressurization (when the compressor 4a is stopped) to prevent malfunction due to sticking of the solenoid valve 20.
Therefore, water soap or bubbles of water soap, evaporated components, and the like do not flow from the air supply pipe 4b to the compressor 4a.

The pressure sensor 13 is linked to the control unit 17 from a well-known pressure switch using a strain gauge or a magneto-resistive element, and utilizes a change in electric resistance accompanying a change in the pressure in the water soap storage tank 1. Pressure vessel 1
The internal pressure is transmitted to the control unit 17 as an electric signal.

The control unit 17 receives a detection signal from the pressure sensor 13 and, when the pressure in the pressure vessel 1 reaches the low-side set pressure, drives the compressor 4a to change the pressure inside the pressure vessel 1 to the high-side set pressure. Compressed air is supplied so that the compressor 4a is stopped when the pressure reaches the high side set pressure, the inside of the pressure vessel 1 is maintained at a predetermined pressure, and each stage is detected by the remaining amount detector 14 of water soap. An LED is displayed on the remaining amount display unit 18 every time.
The system switch 19 is turned on when the lid cover 25 is completely closed, and the system switch 19 is turned on when the lid cover 25 is completely sealed, and the compressor 4a described above is driven by the transmitted signal. In addition,
The difference between the low-side set pressure and the high-side set pressure should be a value that can withstand simultaneous use and continuous use (a value that does not cause trouble) depending on the number of simultaneous discharge ports. Also, the high side set pressure should be set to an acceptable value for the tank (a value that gives the tank some margin).

The control unit 17 is composed of an IC, a capacitor and the like, and is formed by covering the outer frame with a box made of a metal member to prevent malfunction and runaway of the control unit 17 due to noise or the like.
In addition, the electric components such as the control unit 17 and the compressor 4a are covered by an insulating cover made of a non-metallic member (resin) to prevent external static electricity from directly entering the box covering the control unit 17, thereby being built in. Protects electrical components.

The above numerical values show only one embodiment and are not subject to any restrictions. The control unit 17 includes:
When the water and soap leak due to damage to the pressure vessel 1, the water soap output pipe 2, the air output pipe 3, the discharge nozzle 6, etc., which will be described later, the operation of the compressor 4a is stopped and an abnormality indicator light (not shown) It is optional to add various functions conceivable within the scope of the present invention, such as lighting of ()).

The remaining amount detecting unit 14 is linked to the control unit 17 by a reed switch type multipoint detecting liquid level sensor or the like. For example, the inside of each of float stoppers 14b provided on the guide shaft 14a at each stage. Float magnet 14
is configured to move up and down in accordance with the increase and decrease of the water soap, to detect the remaining amount of the water soap at each stage, and transmit it to the control unit 17 (see FIGS. 1 and 7).

In this embodiment, the float magnet 14
By restricting the movement position of c by the frame like the float stopper 14b (communication inside and outside the frame is made by the water hole 14e ...), the influence of the wave of the liquid level in the pressure vessel 1 is reduced.

The lowest detection unit 1 of the remaining amount detection unit 14
4 'is positioned higher than the water soap outlet 2c of the water soap output pipe 2 , and when the remaining water level of the water soap falls below the detection unit 14', the operation of the compressor 4a is stopped and the water soap output pipe 2 is moved to the water soap output pipe 2. The air may be prevented from entering.

In the figure, reference numerals 14d indicate protrusions for preventing the float magnet 14c from adhering, and reference numeral 21 indicates a remaining amount detector for the water soap.
Is a buzzer that issues an alarm via the control unit 17 when the highest detection unit 14 ″ is detected.

The power source (main switch) may be 100 V AC or a dry battery, or both may be used in combination. The water soap output pipe 2 communicates with the inside of the room 8 on the bottom surface 1b of the room 8, and the air output pipe 3 communicates toward the air reservoir 10 of the room 8, and also branches into a plurality of pieces in the middle respectively. And the branched supply pipes 2a

The check valves 22, 22 are provided, for example, in valve chambers 22a, 22a provided in a vertical pipe section 61 as shown in the figure, and include spherical valve bodies 22b, 22b and the valve. Body 22b, 22b
Are closed by the funnel-shaped valve seats 22c and 22c, respectively, and are closed only by the own weight of the valve body 22b.

Therefore, the check valves 22 and 22 are not always biased in the valve closing direction by a spring, and the simple spherical valve bodies 22b and 22b are brought into contact with the valve seats 22c and 22c only by their own weight. Since the valve is closed in contact with water, the amount of soap in the pressure vessel 1 decreases, and even if the inside of the vessel 1 is in a low water pressure range, the push-up force of the valve bodies 22b, 22b is not hindered. Supply.

Each of the nets 6k... May be provided at desired intervals as shown in the drawing, or may be formed by superimposing the nets 6k.

(Fineness) can be selected.

Further, the momentum at the time of discharging the soap can be selected according to the diameter of the discharge port portion 6c. The open / close valve 6h may be an electric or electromagnetic type that opens for a certain period of time by an electric signal based on the detection of a hand by a human sensor such as a photoelectric sensor or a pressing operation of a touch switch. The valve may be a manual type that opens while the button 6f is pressed or is operated for a certain period of time, but the illustrated example shows a manual open / close valve 6h by operating the push button 6f.

When the push button 6f is pressed at the discharge nozzle 6, the compressed air and water soap mix in the discharge nozzle 6, and are stirred by the mesh body 6k and discharged in a mousse state. Further, according to the present embodiment, the partition wall 5 provided in the pressure vessel 1 has a reinforcing effect, and the strength of the pressure vessel 1 can be improved in manufacturing, pressure resistance, and the like. 5, the air supply pipe 4b communicating with the compressor 4a and the like is provided on one side and the air output pipe 3 communicating with the discharge nozzle 6 is provided on the other side. The bubbling of the water soap in the container 1 generated when the compressed air is supplied into the pressure container 1 prevents the partition wall 5 from entering the room 8 on the side provided with the air output tube 3, and as a result, Can effectively prevent the penetration of bubbles.

Further, since the supply port 9 for water soap is provided in the room 8 provided with the air supply pipe 3 of the container 1, the swinging of the water soap in the container 1 due to the supply of water soap is performed by the partition wall 5.
