The delay of the fluid reservoir S1 depends on the pipe resistance of the discharge pipe.
Since one bent portion T2 formed by bending the tube T1 into a substantially U-shape is formed between the fluid reservoir S1 and the pump 430, the pipeline resistance is increased. The bent portion T2
Is located below the check valve V1 on the suction pipe side described above. The bent portion T2 is formed at a position close to the bottom surface of the tank body 31.

The mixing chamber 104 of the fluid mixing means 100
Is for mixing the first fluid (water soap) and the second fluid (air), and communicates with the pair of lower passages 271 respectively.

The mixing chamber 104 has a first discharge port 105 from which a first fluid (water soap) can be discharged, a second discharge port 106 from which a second fluid (air) can be discharged, and a partition wall 107. . The partition 107 allows the second fluid to flow from the second discharge port 106 to the first discharge port 105 side, while preventing the first fluid from entering the first discharge port 105 to the second discharge port 106 side. It is arranged to block.

In the present embodiment, the first fluid and the second fluid are discharged from below, and the partition 107 is provided upright around the second discharge port 106, and the wall of the mixing chamber 104 is also formed. It constitutes a part of the partition 107. The partition 107 has a slit 108 formed therein. Slit 108

It is a gap that is blocked by fluid (water soap). Although the slit 108 is formed in the shape of a long groove in the vertical direction, the slit 108 may be formed in the shape of a long groove in the horizontal or oblique direction, and the number of the slits 108 is not limited to one and may be two or more.

The second discharge port 106 is connected to the first discharge port 10.
It is located higher than 5. That is, the step 109 is provided between the floor of the mixing chamber 104 where the second discharge port 106 is opened and the floor of the mixing chamber 104 where the first discharge port 105 is opened.

Next, the operation of the fluid supply device will be described. In FIG. 1, when the cover member 60 is pressed downward against the restoring force of the coil spring provided in the cylinder 431, the piston member 432 is moved through the piston rod 433.
Moves downward in the cylinder 431, and
0 moves down. Thereby, the first fluid (water soap) in the cylinder 431 flows into the mixing chamber 104 through one of the pair of connection pipes 103 of the fluid mixing means 100 through the discharge pipe (the discharge pipe 436 and the tube T1). I do.

At this time, since the hole 435 for absorbing the impact force is formed in the piston member 432, the piston member 4
Even if the piston 32 moves rapidly downward and the volume of the piston member 432 decreases rapidly, the volume of the hole 435 for absorbing the impact force remains, so that the volume in the cylinder 431 is substantially rapidly reduced. Instead, it is possible to prevent the impact force from being transmitted to the supply path (the discharge pipe 436 to the tube T1 to the connection pipe 103 of the fluid mixing unit 100) of the first fluid (water soap).

The second fluid (air) in the air chamber 441
Flows through the tube from the air discharge line 418 and the other spherical valve 1 of the pair of connecting tubes 103 of the fluid mixing means 100
02 is pushed up against the urging force and flows into the mixing chamber 104 to foam the first fluid (water soap) in the mixing chamber 104. The foamed first fluid (water 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 420 also moves upward, the internal pressure of the cylinder 431 decreases, and the first fluid ( Water soap) flows into the cylinder 431 through the extension pipe 438 and the check valve V1. Further, outside air flows from the air valve 110 through the tube into the air chamber 441 from the air suction pipe 417. Thereby, the next first fluid (water soap) and the second fluid
It can be provided for the supply of fluid (air).

Next, the operation of the fluid mixing means 100 when mixing the first fluid (water soap) and the second fluid (air) will be described. First discharge operation of pump 430

0 of the first discharge port 10 through one of the pair of connecting pipes 103.
5 to the mixing chamber 104. Also, the second fluid (air) passes through the tube from the air discharge line 418,
The other spherical valve 102 of the pair of connecting pipes 103 of the fluid mixing means 100 is pushed up against the urging force and is rectified and sent from the second discharge port 106 to the mixing chamber 104.

A partition 107 is provided in the mixing chamber 104 to control the flow of the first fluid and the second fluid. That is, the partition 107 is provided with the second fluid in the second discharge port 1.
06 to the first discharge port 105 side, but the first fluid flows from the first discharge port 105 to the second discharge port 106.
Prevent from entering the side. This prevents the first fluid from sneaking into the second discharge port 106 of the second fluid,
The flow of the second fluid becomes appropriate, and the second fluid can be properly mixed with the first fluid. That is, for example, the second fluid is discharged from the second discharge port because the first fluid does not flow into the second discharge port 106, and part or all of the second discharge port 106 is not blocked by the first fluid. In this case, since no pulsation occurs, the blowing of the second fluid into the first fluid is maintained in a good state, and the first fluid that is an appropriate foam-like water soap can be generated.

The partition 107 can take various forms depending on the flow of the first fluid and the second fluid. As in the embodiment, the first fluid is discharged from the lower first discharge port 105 and In the case where the two fluids are discharged from the lower discharge port 106 and the partition 107 is erected around the second discharge port 106, the first fluid passes over the partition 107 and the second fluid
Since it is difficult to go around the discharge port 106, the first fluid is prevented from entering the second discharge port 106.

The partition 107 is provided with a slit 108 for communicating the first discharge port 105 and the second discharge port 106, and the slit 108 extends from the second discharge port 106 to the first discharge port 106.
Although the second fluid that is going to flow into the discharge port 105 side can pass through, the first fluid that is going to enter the second discharge port 106 side from the first discharge port 105 spreads into the slit 108 due to surface tension, 108 will be blocked.

Further, in the embodiment, the second discharge port 106
Is opened at a position higher than the first discharge port 105, so that the first
It is necessary for the fluid to climb over the step portion 109 and go around to the second discharge port 106 located at a high position, and it is possible to make it difficult for the first fluid to go around. By providing the partition 107 and the step 109, it is possible to make it extremely difficult for the first fluid to wrap around.

In the above-described embodiment, the first fluid, which is water soap, is mixed with the second fluid, which is air. However, the first fluid and the second fluid to be mixed are water soap. The present invention is not limited to air, and the mixing is performed by flowing the second fluid toward the first fluid, but any mixing is not performed by flowing the first fluid toward the second fluid. It may be something.

Further, the slit 108 is formed in the shape of a long groove in the vertical direction, but may be formed in the shape of a long groove in the horizontal direction or the oblique direction. May be.

Further, the partition wall 107 including the chamber wall erected on the floor of the mixing chamber 104 surrounds the second discharge port 106. However, if the first fluid can be prevented from flowing around, the first discharge port 106 can be prevented. A partition may be provided upright between the discharge port 105 side and the second discharge port 106 side.
