The gas outflow hole 97 (cylinder hole 94) is closed from the gas / liquid storage chamber S and the valve is closed (hereinafter referred to as “compressed gas introduction position P5”).

In the compressed gas supply device 9, first, the operation handle 92 is grasped and the piston shaft 91 is pulled in the direction of pulling out from the inside of the cylinder 86 (direction A in FIG. 4).
When the operation handle 92 is pulled, the lower space K1 (first) formed (partitioned) between one cylinder end 86A (cylinder closing plate 93) of the cylinder 86 and the piston body 111 (first piston disk 116). 1 space) becomes a negative pressure (negative pressure state) as shown in FIG. 23.

When the lower space K1 becomes negative pressure, the upper space K2 (partition) formed (partitioned) between the piston body 111 (second piston disk 117) and the cylinder end 86B (lid plate 22) on the other side of the cylinder 86. The gas AX (air) in the second space) flows from the upper space K2 toward the lower space K1 and acts on the seal ring 112.
As shown in FIG. 23, the seal ring 112 slides on the cylinder hole 94 (inner peripheral surface of the hole) of the cylinder 86 by the gas AX flowing from the upper space K2 toward the lower space K1, and the second piston disk 117. Is moved to the first piston disk 116 and pressed against the first piston disk 116.
As a result, the gas AX (air) in the upper space K2 is between the gap τ (between the second piston disk 117 and the cylinder hole 94), the inner peripheral surface 112B of the seal ring 112, and the outer peripheral surface 115C of the piston shaft 115. It flows into the lower space K1 through the gap and each gas flow groove 121.

When the operation handle 92 is pulled, the piston main body 111 is arranged at a position where it abuts on the lid plate 22 (hereinafter, referred to as “gas initial position P6”) as shown in FIG. 22.

In the compressed gas supply device 9, when the operation handle 92 is pushed from the gas initial position PS toward the compressed gas introduction position P5, the piston body 111 reduces the volume of the lower space K1 while reducing one of the cylinders 86. It is moved to the cylinder end 86A (cylinder closing plate 93 side) of the cylinder.
As a result, the gas AX in the lower space K1 is compressed, and the lower space K1 is in a high pressure state.

As shown in FIG. 9, the gas A (compressed gas) compressed in the lower space K1 acts on the seal ring 112 through the gap T (between the first piston disk 116 and the cylinder hole 94).
As a result, the seal ring 112 slides on the cylinder 86 (the inner peripheral surface of the hole of the cylinder hole 94) by the compressed gas A (compressed air) from the first piston disk 116 toward the second piston disk 117. It is moved and pressed against the second piston disk 117.
As shown in FIG. 9, the seal ring 112 closes the gap τ (between the second piston disk 117 and the inner peripheral surface of the cylinder hole 94) and shuts off (closes) the lower space K1 from the upper space K2. do.

In the cylinder 86, the compressed gas A in the lower space K1 flows into the gas introduction chamber SQ (inside the circular protrusion 105) through each gas outflow hole 97 as shown in FIG.
The compressed gas A flowing into the gas introduction chamber SQ acts uniformly on the valve plane 100A (substantially the entire surface of the valve plane 100A) of the check valve body 100.

When the compressed gas A in the lower space K1 (gas introduction chamber SQ) reaches a certain pressure or higher (more than the internal pressure of the fluid container 1 / higher than the water pressure of the liquid W), the outer peripheral side of the check valve body 100 is elastically deformed. , Separated from the circular protrusion 105 (valve seat).
As a result, the check valve 88 elastically deforms the check valve body 100 (valve outer peripheral side) by the action of the compressed gas A, opens each gas outflow hole 97, and opens the valve. The lower space K1 (communication hole 95) communicates with the gas / liquid storage chamber S through each gas outflow hole 97 and a check valve 88.

When the piston body 111 is moved from the initial gas position P1 to the compressed gas introduction position P5 in the compressed gas supply device 9, the upper space K2 has a shaft hole 122 (shaft hole) of the shaft boss 90 as shown in FIG. 24. The outside air (air) flows in (introduces) through the gap between 122 and the piston shaft 91.

When each gas outflow hole 97 is opened and the valve is opened, as shown in FIG. 9, the compressed gas A passes through each gas outflow hole 97 from the upper space K1 of the cylinder 86 (communication hole 95) and passes through each gas outflow hole 97, and the gas / liquid storage chamber S It is jetted (spouted) inside.

The compressed gas A injected into the gas / liquid storage chamber S is injected into the liquid W stored in the fluid container 1 (gas / liquid space AW) from each gas / liquid injection hole 99 together with the liquid W in the gas / liquid storage chamber S. The liquid. When all the liquids W in the gas / liquid storage chamber S are ejected from the gas / liquid injection holes 99 into the liquid W stored in the fluid container 1, the compressed gas A passes through the gas / liquid storage chamber S and becomes each liquid. It is injected from the injection hole 99 into the liquid W stored in the fluid container 1.
Each gas-liquid injection hole 99 is depressurized while increasing the flow velocity of the compressed gas A, and is injected into the liquid W stored in the fluid container 1.

When the compressed gas A is injected into the liquid W stored in the fluid container 1, the compressed gas A and the liquid W in the region where the compressed gas A is injected (the region between the bottom 13 and the cylinder lid 87) collide with each other. It becomes a turbulent flow. The compressed gas A becomes bubbles (for example, bubbles of several millimeters) in the liquid W due to turbulent flow (collision), and is mixed and dissolved in the liquid W.
As a result, the amount of dissolved gas (the amount of air bubbles mixed and dissolved in the liquid W) of the liquid W stored in the fluid container 1 (gas-liquid space AW) is increased.

As shown in FIG. 4, when the compressed gas A is injected (spouted) into the liquid W stored in the fluid container 1, it becomes bubbles in the liquid W and becomes a gas space R (the other cylinder end of the container body 10). 10B, it flows in the liquid W toward the fluid mixer 3) and is stored (filled) in the gas space R.
In this way, the compressed gas supply device 9 repeats the gas initial position PS and the compressed gas introduction position P5 once or a plurality of times to increase the amount of dissolved gas of the liquid W stored in the fluid container 1 while increasing the amount of dissolved gas. A sufficient amount (sufficient volume) of compressed gas A is stored (filled) in the gas space R of the fluid container 1.

When all the compressed gas A in the upper space K1 is injected into the fluid container 1, the liquid W stored in the fluid container 1 flows into the gas / liquid storage chamber S from each gas / liquid injection hole 99, and the check valve 88 is reversed. It acts on the check valve body 100. As a result, as shown in FIG. 9, the check valve 88 abuts the valve plane 100A of the check valve body 100 against the circular protrusion 105 by the liquid W (water pressure of the liquid W) in the air-liquid reservoir S. , Each gas outflow hole 97 is closed to shut off (close) the cylinder 86 (cylinder hole 94, connecting hole 95) from the inside of the fluid container 1 (stored liquid W).
As a result, the liquid W stored in the fluid container 1 flows back into the cylinder 86 by closing each gas outflow hole 97 with the check valve 88, and does not flow into the cylinder 86.

When the compressed gas A is stored (filled) in the gas space R of the fluid container 1 in the spray mist X, a human finger is put on the operation lever 83 and the operation lever 83 is pulled to the fluid container 1 side (body portion 12 side). Rotate to open (see FIG. 25).
As shown in FIG. 25, the operating lever 83 is rotated (turned) in one direction from the initial position P1 about the rotation shaft 82. The operating lever 83 is rotated (turned) toward the container body 10 side from the initial position P1 against the spring force (urging force) of the valve spring 78.
As a result, the operating lever 83 that abuts on the valve shaft 79 (the other valve shaft end 79B) causes the valve shaft 79 (valve body 80) to resist the spring force (urging force) of the valve spring 78 by the opening operation. Move to the spring storage space SP (inside the spray body 40).
As shown in FIGS. 25 and 26, the valve body 76 (valve shaft 79, valve body 80) is rotated in one direction (opening operation) of the operating lever 83 in the cylinder center line direction D of the gas-liquid cylinder 30. And is pushed into the spring storage space SP (spray body 40).
As a result, the valve body 80 is separated from the valve seat 75 in the cylinder center line direction D, as shown in FIGS. 25 and 26.
The on-off valve 6 opens the fluid passage 42 by separating the valve body 80 from the valve seat 75. The fluid passage 42 communicates with the fluid mixing chamber M through the fluid hole 53 by opening the on-off valve 6.

As shown in FIG. 25, the operation lever 83 abuts the spray shaft 41 on the hole upper plan 84A of the operation hole 84 by rotation in one direction, and stops the rotation (swivel) in one direction.
As a result, the movement of the valve body 76 is stopped, and the valve body 80 opens the valve to one cylinder end 30A (closing plate 35) of the gas / liquid cylinder 30 in the cylinder center line direction D of the gas / liquid cylinder 30. It is arranged at intervals ε (valve opening gap).
In this way, the valve opening / closing body 7 opens the on-off valve 6 by the opening operation (rotation in one direction) of the operating lever 83, and communicates the fluid passage 42 with the fluid mixing chamber M.

When the on-off valve 6 is opened and the fluid passage 42 is communicated with the fluid mixing chamber M, the compressed gas A stored in the gas space R of the fluid container 1 passes through each gas ejection hole 34 as shown in FIG. Then, the gas is injected (spouted) into the fluid mixing chamber M toward the cylinder center line direction D (direction B orthogonal to the liquid level WL) of the gas-liquid cylinder 30.
When the compressed gas A is injected into the fluid mixing chamber R, the inner circumferences of the fluid mixing chamber M, the valve body 80, and the gas-liquid cylinder 30 toward the cylinder center line direction D (direction B orthogonal to the liquid level WL). It flows through the fluid passage 42 (spring storage space SP) through the gap between the surfaces 30C, the opening / closing valve 6 (the gap between the valve body 80 and the valve seat 75), and the fluid hole 53 of the fluid passage 42. ..
The liquid W in the liquid tube body 8 (the liquid in which the amount of dissolved gas stored in the fluid container 1 is increased) is injected into the fluid mixing chamber M of the compressed gas A through the liquid ejection hole 33 and the fluid mixing chamber M. Is jetted (spouted). The liquid W in the liquid tube body 8 is injected into the fluid mixing chamber M due to the injection of the compressed gas A into the fluid mixing chamber M. As shown in FIG. 26, the liquid W in the liquid tube body 8 is pulled into the liquid ejection hole 33 (fluid mixing chamber M) through the liquid tube body 8 by the flow of the compressed gas A injected into the fluid mixing chamber M. Then, the gas is injected into the fluid mixing chamber M between the gas ejection holes 34 through the liquid tube body 8 and the liquid ejection hole 33.

Each gas ejection hole 34 is depressurized while increasing the flow velocity of the compressed gas A, and the compressed gas A is injected into the fluid mixing chamber M, and the liquid ejection hole 33 is depressurized while increasing the flow velocity of the liquid W. , The liquid W is injected into the fluid mixing chamber M between the gas ejection holes 34.
As a result, the liquid W is injected into the liquid air ejection chamber M following the injection of the compressed gas A.

As shown in FIG. 26, when the compressed gas A is injected into the fluid mixing chamber M, it flows in the cylinder center line direction D (direction B orthogonal to the liquid level WL) of the gas-liquid cylinder 30 and the valve opening gap. At ε, it collides with the valve body 80 and becomes a turbulent flow.
When the liquid W is injected into the fluid mixing chamber M, it flows toward the compressed gas A (compressed gas) and collides with the valve body 80 in the valve opening gap ε to form a turbulent flow.
When the liquid W is injected into the fluid mixing chamber M, it collides with the compressed gas A while entraining the compressed gas A, and in the fluid mixing chamber M, the compressed gas A and the liquid W are mixed to form microbubbles and ultrafundle bubbles. It becomes a fine droplet AW (hereinafter referred to as "fine droplet or fine mist") mixed and melted.
The amount of dissolved gas in the liquid W injected into the fluid mixing chamber M is increased, and in the fluid mixing chamber M, a large amount of bubbles in the liquid W are generated due to the collision (turbulent flow) between the compressed gas A and the liquid W. It is crushed (sheared) into microbubbles and ultrafine bubbles, and becomes a fine droplet AW (fine mist) in which a large amount of microbubbles and ultrafine bubbles are mixed and melted.
In this way, in the fluid mixing chamber M, the compressed gas A and the liquid W having an increased amount of dissolved gas collide with each other, and the compressed gas A and the liquid W are mixed, so that a large amount of microbubbles and ultrafine bubbles are mixed and melted. Generates fine droplets (fine mist).

As shown in FIG. 26, the fine droplet AW (fine mist) and the compressed gas A (gas) pass from the fluid mixing chamber M between the valve body 80 and the valve seat 75, and pass through the fluid hole of the fluid passage 42. It flows into 53 and is injected (spouted) into the spring storage chamber SP (fluid passage 42). As shown in FIGS. 25 and 27, the fine droplet AW and the compressed gas A (gas) are placed between the spring storage space SP (valve shaft 79 and the first and second spring storage holes 46 and 49) of the fluid passage 42. ), And flows through the flow hole 52 (inside the spray shaft 41) and flows into the mist generator Y.
As shown in FIG. 27, the fine droplets AW and the compressed gas A pass through the gas-liquid flow holes 69 (gap δa) of the guide disk 63 from the fluid passage 42 (flow hole 52) and the mist drawing hole 60. Inflow to.

As shown in FIG. 27, the fine droplets AW and the compressed gas A that have flowed into the mist drawing hole 60 flow through the spiral first and second mist flow paths α and β, and are on the nozzle drawing hole 59 side. It is sprayed (spouted) into the mist drawing hole 60.
As shown in FIG. 27, the fine droplet AW and the compressed gas A (gas) are depressurized while increasing the flow velocity by flowing through the spiral first and second mist flow paths α and β. It is sprayed from the first and second mist flow paths α and β into the mist throttle hole 60 on the nozzle throttle hole 59 side. Further, through the mist drawing hole 60 and the nozzle drawing hole 59, a large amount of microbubbles and ultrafine bubbles are mixed and melted into the ultrafine droplet AZ (hereinafter referred to as "ultrafine droplet or ultrafine mist"). ), It is sprayed (sprayed) from the spray nozzle 5 to the outside (outside).
As a result, the fine droplets AW and the compressed gas A ejected from the first and second mist flow paths α and β into the mist throttle hole 60 become turbulent at high pressure.
The fine droplet AW collides with the compressed gas A injected into the mist drawing hole 60 in the mist drawing hole 60 on the nozzle drawing hole 59 side, and the fine droplet AW and the compressed gas A are mixed to form a pole. It becomes a fine droplet AZ (ultra-fine mist). The ultrafine droplet AZ is a fine particle finer than the fine droplet AW, and is an ultrafine particle close to gas, such as in a cloud or fog.

When fine droplet AZ is ejected (sprayed) from the nozzle drawing hole 59 (mist drawing hole 60), it is on the outlet side (the side on which the fine droplet AZ is ejected) of the nozzle drawing hole 59 (mist drawing hole 59). It becomes a negative pressure state.
By setting the outlet side of the mist drawing hole 69 (nozzle drawing hole 59) to a negative pressure state, the high pressure and high pressure flowing out from the first and second mist flow paths α and β to the mist drawing hole 60 on the nozzle drawing hole 59 side. When the turbulent fine droplets AZ pass through the outlet portion of the mist drawing hole 60, bubble precipitation due to depressurization and the gas entrained during injection are crushed (sheared) by the turbulent flow, resulting in fine droplets. Further than AW, a large amount of microbubbles and ultrafine bubbles are mixed and melted into ultrafine droplets AZ (ultrafine mist).
Further, the fine droplet AZ is ejected from the first and second mist flow paths α and β facing each other into the mist throttle hole 60 on the nozzle throttle hole 59 side at the conical upper surface 65A of the mist guide 65 and collides with each other. Then, it becomes an ultrafine droplet AZ.
As shown in FIG. 27, the ultrafine droplet AZ is sprayed (sprayed) from the nozzle throttle hole 59 of the spray nozzle 5 through the mist throttle hole 60. The mist drawing hole 60 injects (sprays) ultrafine droplets AZ from the nozzle drawing hole 59 to the outside (outside).

In the mist spray X, when a person's finger is released from the operation lever 83 to close the valve body 76, the valve body 76 is moved in the cylinder center line direction D of the gas-liquid cylinder 30 by the spring force (urging force) of the valve spring 78. The other valve shaft end 79B side of the valve shaft 79 protrudes from the spring storage space SP (inside the spray body 40) (see FIGS. 4 and 25).
As a result, the on-off valve 6 presses the valve body 80 against the valve seat 75, closes the fluid passage 42 (fluid hole 53), and closes the valve.
The fluid passage 42 is shut off (closed) from the fluid mixing chamber M by closing the on-off valve 6.

As shown in FIGS. 4 and 25, the operating lever 83 is separated from the fluid container 1 side (body portion 12 side) by the valve shaft 79 protruding from the spring storage space SP (inside the spray body 40) and in the other direction. It is rotated (turned) to. The operation lever 83 abuts the spray shaft 41 on the lower end 84B of the hole 84 of the operation hole 84 by the rotation (swivel) of the other, and stops the rotation of the other.
As a result, the movement of the valve body 76 is stopped, and the valve body 80 is pressed against the valve seat 75 by a constant pressure to close the fluid passage 42 from the fluid mixing chamber M and close the valve.

The mist spray X can also adopt a configuration that does not include the mist generator Y, and the fine droplet AW (fine mist) is sprayed (sprayed) from the spray nozzle 5 (nozzle narrowing hole 59) to the outside (outside). ..

In the mist spray X, the liquid stored in the fluid container 1 by setting the gas storage amount VA (liquid storage depth LA) of the compressed gas A to be larger than the liquid storage amount VW (liquid storage depth LW) of the liquid W. Sufficient compressed gas capable of injecting (spraying) all of W as fine droplets AW (ultrafine droplets AZ) can be stored (filled) in the liquid container 1.
As a result, using a sufficient amount of compressed gas A (pressure of compressed gas A), all of the liquid W stored in the fluid container 1 is used as fine droplets AW (ultrafine droplets AZ), and the spray nozzle is used. It is possible to spray (spray) from 5 (nozzle throttle hole 59).
Further, when the pressure of the compressed gas A injected into the fluid mixing chamber M drops, the compressed gas A is stored (filled) in the fluid container 1 (gas space R) by the compressed gas supply device 9, so that the fluid is fluidized. All of the liquid W stored in the container 1 can be sprayed (sprayed) from the spray nozzle 5 (nozzle narrowing hole 59) as fine droplets AW (ultra-fine droplets AZ).

The present invention is optimal for injecting fine droplets.
