The vortex forming groove 81 is formed, for example, on one side of the second guide plate 74, by recessing the plate surface 74A of the second guide plate 74 adjacent to the central shaft portion 76. 16, 18 and 20, the vortex forming groove 81 communicates with the liquid introduction hole 79 at the position of the maximum groove width HW and maximum depth WM.

The outer circumferential surface 76a on the other side of the central shaft portion 76 with respect to the reference line LA as the boundary (the outer circumferential surface 76a of the lower half of the central shaft portion 76) forms a groove inner circumferential surface 82b of the vortex forming groove 82.

The groove depth of the vortex forming groove 82 is the same maximum groove depth WM as that of the vortex forming groove 81 at the hole center line t of the liquid introduction hole 80 (the cylinder center line n of the liquid introduction cylindrical portion 78) and is the same minimum groove depth WN (WN = 0) as that of the vortex forming groove 81 at the position of the hole center line s of the liquid introduction hole 79 (the position of the cylinder center line m of the liquid introduction cylindrical portion 77).

[0078] As shown in Figures 4 and 7, the vortex forming body 3 (first and second guide tube portions 71, 72) is concentric with the tube main body 1 and arranged in the inflow space α (inflow hole β) between the partition body 2 (partition main body 51) and the inflow port 13. The vortex forming body (first and second guide tube portions 71, 72) are concentric with the tube main body 1 and arranged in the inflow space α (inflow hole β) between the closure plate 37 (inflow port 13) of the cover member 19 and the partition body 2 (partition main body 51).

[0079] As shown in Fig. 4 and Fig. 7, the vortex forming body 3 is arranged in the inflow space α (inflow hole β) with one cylinder end 71A (each vortex forming groove 81, 82) of the first guide tube part 71 facing the partition body 51 (annular flat plate 53 and wire mesh 54) and each liquid introduction tube part 77, 78 facing the closing plate 37 (inflow port 13) of the cover member 19. The vortex forming body 3 is connected to the cylindrical member 17 (tube part 24) by inserting one cylinder end 71A side of the first guide tube part 71 into the cylindrical member 17 (tube part 24) from the other cylinder end 24B of the cylindrical member 17 (tube part 24). One cylinder end 71A side of the first guide tube part 71 is inserted into the cylindrical member 17 (tube part 24) with the outer peripheral surface 71a of the first guide tube part 71 in close contact with the inner peripheral surface of the tube part 24.

[0080] In the vortex forming body 3, when one cylinder end 71A side of the first guide tube part 71 is inserted into the tube part 24, the first guide plate 73 and the second guide plate 74 form (partition) a gas-liquid mixing chamber τ2 between them and the partition body 51 (the annular plate 53 and the wire mesh 54) as shown in Figures 4 and 7. In the vortex forming body 3, when one cylinder end 71A side of the first guide tube part 71 is inserted into the tube part 24, the second guide tube part 72 is disposed inside the flow hole 55 of the partition body 51, and each vortex forming groove 81, 82 is disposed opposite the wire mesh 54 (each outflow hole 52 / each mesh ε) of the partition body 51. In the vortex forming body 3, when one cylinder end 71A side of the first guide cylinder part 71 is inserted into the cylinder part 24, each vortex forming groove 81, 82 is opened to the gas-liquid mixing chamber τ2 and communicates with each outflow hole 52 (each mesh ε of the wire mesh 54) through the cylinder hole 25 of the cylindrical member 17 (cylinder part 24) as shown in Fig. 4 and Fig. 7. Each outflow hole 52 (each mesh ε) penetrates the partition body 51 (wire mesh 54) in the direction A of the cylinder center line a of the cylinder body 1, and opens (communicates) with an opening area Sp to the outflow chamber τ1 and the gas-liquid mixing chamber τ2 (cylinder hole 25). The opening area Sp of each outflow hole 52 is the size of the outflow hole 52 (mesh ε), and is, for example, the sum of the horizontal line interval δ1 and the vertical line interval δ2 (Sp = δ1 x δ2). In the vortex forming body 3, the first guide flat plate 73 and the second guide plate 74 have vortex forming grooves 81, 82 that form (partition) an inflow chamber τ3 between the closing plate 37 (inlet 13) of the cover member 19 when one cylinder end 71A side of the first guide tube portion 71 is inserted into the tube portion 24.

[0082] As shown in Figure 7, the vortex forming body 3 is fixed to the cylindrical main body 1 by clamping the flange portion 75 between the cover member 19 (step portion 41) and the cylindrical member 17 (tubular portion 24) with the plate surface 75A of the flange portion 75 abutting against the other cylindrical end 24B of the cylindrical member 17 (tubular portion 24) and the plate back surface 75B of the flange portion 75 abutting against the step portion 41 of the cover member 19. The cover member 19 and the cylindrical member 17 are in a state in which the plate surface 75A of the flange portion 75 is abutted against the other cylindrical end 24B of the cylindrical member 17 (tubular portion 24) and the plate back surface 75B of the flange portion 75 is abutted against the step portion 41 of the cover member 19.By rotating the cover member 19 relative to the cylindrical member 17, the male threaded portion 28 of the cylindrical member 17 is screwed into the female threaded portion 36 of the cover member 19, and the flange portion 75 is clamped by the cylindrical portion 34 (step portion 41) and the cylindrical portion 24, thereby fixing the vortex forming body 3 to the cylindrical main body 1. When the vortex forming body 3 is fixed to the tube body 1, the inflow chamber τ3 is formed by the conical hole 45 of the inflow hole β (inflow space α) between the inlet 13 (the closing plate 37 of the cover member 19) and the vortex forming body 3 (the first guide plate 73 and the second guide plate 74) and the small diameter hole portion 40 of the tube hole 35. In the inflow chamber τ3, the conical hole 45 of the cover member 19 gradually expands in diameter from the inlet 13 toward the small diameter hole portion 40 of the tube hole 35 (cover member 19) in the direction A of the tube center line a of the tube body 1, and communicates with the small diameter hole portion 40.

As shown in FIG. 31, the second sphere 6Y has, for example, a pair (two) of recesses 87 (recesses), and the pair of recesses 87, 87 are arranged with an acute angle (for example, an angle of 90 degrees) between the center lines ψ of each recess 87, 87 (recesses), centered on the sphere center ω of the second sphere 6Y. The second sphere 6Y has one or more recesses 87 formed in the surface 5a (spherical surface) of the second sphere 6Y.

[0096] As shown in FIG. 32, the third sphere 6Z is formed into a sphere having a diameter Dw equal to the spherical diameter of the first sphere 6X (see FIG. 30). The third sphere 6Z has a plurality of through holes 88 (third through holes) that are opened on the surface 6a (spherical surface) of the third sphere 6Z and penetrate the third sphere 6Z. Each through hole 88 is formed, for example, as a circular hole (circular hole) having a diameter Dz smaller than the diameter Dx of the third sphere 6Z. Each through hole 88 (third through hole) penetrates the third sphere 6Z and opens on the spherical surface 6a (surface) of the third sphere 6Z. 32, the third sphere 6Z has, for example, a pair (two) of through holes 88, 88, and the pair of through holes 88, 88 are arranged with an acute angle (for example, an angle of 90 degrees) between the hole center lines μ of each of the through holes 88, 88, centered on the sphere center ω of the third sphere 6Z. The pair of through holes 88, 88 pass through the sphere center ω of the third sphere 6Z, penetrate the third sphere 6Z, and open to the spherical surface 6a (front surface) of the third sphere 6Z. The third sphere 6Z has a through hole 88 formed therein, the through hole 88 being opened on the surface 6a (spherical surface) of the third sphere 6Z and penetrating the third sphere 6Z.

[0097] Each of the three types of floating bodies 4, 5, 6 (each of the first to third floating bodies / floating bodies) is composed of one of the first spheres 4X, 5X, 6X, the second spheres 4Y, 5Y, 6Y, or the third spheres 4Z, 5Z, 6Z, as shown in Figures 4 and 33, and one or more are arranged (stored) in the gas-liquid mixing chamber τ2 so as to be freely movable (movable). One or more spheres (floating bodies) are arranged (stored) in the gas-liquid mixing chamber τ2. The three types of floating bodies 4, 5, 6 (each type of floating body) are floating (moving) between the partition body 51 (partition body 2) and the vortex forming body 3 (first guide plate 73, second guide plate 74) in the gas-liquid mixing chamber τ2. Among the three types of floating bodies 4 to 6 (each type of floating body), the first spheres 4X, 5X, 6X, the second spheres 4Y, 5Y, 6Y, and the third spheres 4Z, 5Z, 6Z arranged (stored) in the gas-liquid mixing chamber τ2 are floating (moving) between the partition body 51 (partition body 2) and the vortex forming body 3 (first guide plate 73, second guide plate 74) by the liquid flowing through the gas-liquid mixing chamber τ2.

[0098] As shown in Figures 4 and 33, the three types of floating bodies 4, 5, and 6, for example, one or more third spheres 4Z (first floating bodies 4), one or more second spheres 5Y (second floating bodies 5), and one or more first spheres 6X (third floating bodies 6), are arranged (stored) in the gas-liquid mixing chamber τ2 so that they can move freely (be movable).

[0099] 1 to 8 and 33, the bubble liquid generator X is connected to a liquid supply source (not shown), and liquid (e.g., water) flows from the liquid supply source into the inflow space σ (inflow hole β) of the tube main body 1. The bubble liquid generator X connects the boss portion 38 (flow path hole 42) of the cover member 19 (second cover member) to the liquid supply source, and liquid from the liquid supply source is supplied to the flow path hole 42 of the cover member 19. The liquid supplied to the flow path hole 42 of the cover member 19 flows from the inlet 13 into the inflow chamber τ3 (inflow space α / inflow hole β).

[0100] As shown in Figures 4 to 8 and 33, the liquid that has flowed into the inflow chamber τ3 (inflow space α / inflow hole β) fills (fills) the inflow chamber τ3, and also flows into each liquid introduction hole 79, 80 from the other cylindrical ends 77B, 78B of each liquid introduction cylindrical portion 77, 78. The liquid that has flowed into each liquid introduction hole 79, 80 flows through each liquid introduction hole 79, 80 along with the flow of liquid from the inlet 13 into the inflow chamber τ3, and flows out into each vortex forming groove 81, 82 of the vortex forming body 3, filling (filling) the gas-liquid inflow chamber τ2 and the outflow chamber τ1 (inflow space α / inflow hole β). As shown in Figures 4, 7, 8 and 33, when the inflow space α (inflow chamber τ3, gas-liquid mixing chamber τ2 and outflow chamber τ1) is filled (full) with liquid, the liquid flowing through each liquid introduction hole 79, 80 flows out (spouts) into each vortex forming groove 81, 82 of the vortex forming body 3.

[0101] The liquid flowing out (sprayed) from the liquid introduction hole 79 (liquid introduction flow path) into the vortex forming groove 81 (vortex forming flow path) flows along the groove outer peripheral surface 81a and groove inner peripheral surface 81b of the vortex forming groove 81 (vortex forming flow path) from the hole center line s of the liquid introduction hole 79 toward the position of the hole center line t of the liquid introduction hole 80 on one side of the second guide plate 74 (the upper half side of the second guide plate 74), as shown in Figures 8 and 20. The liquid flowing out into the vortex forming groove 81 flows between the groove outer peripheral surface 81a and the groove inner peripheral surface 81b while moving from the groove bottom surface 81c of the maximum groove depth WN of the hole center line s of the liquid introduction hole 79 toward the plate surface 74A of the second guide plate 74. The liquid flowing between the groove outer surface 81a and groove inner surface 81b of the vortex forming groove 81 flows out (sprays) from the vortex forming groove 81 toward the inner surface 72b of the second guide tube portion 72 at the position of the hole center line t of the liquid introduction hole 80, into the second guide tube portion 72 (into the gas-liquid mixing chamber τ2) between one of the tube ends 72A and the second guide plate 74, and flows along the inner surface 72b of the second guide tube portion 72. The vortex forming groove 81 causes the liquid flowing out from the liquid introduction hole 79 to flow (spray) toward the inner surface 72b of the second guide tube portion 72 and into the second guide tube portion 72 (into the gas-liquid mixing chamber τ2), causing the liquid to flow along the inner surface 72b of the second guide tube portion 72.

[0102] The liquid flowing out (sprayed) from the liquid introduction hole 80 (liquid introduction flow path) into the vortex forming groove 82 (vortex forming flow path) flows between the groove outer peripheral surface 82a and groove inner peripheral surface 82b on the other side of the second guide plate 74 (the lower half side of the second guide plate 74) from the hole center line t of the liquid introduction hole 80 toward the position of the hole center line s of the liquid introduction hole 79, along the groove outer peripheral surface 82a and groove inner peripheral surface 82b. The liquid flowing out into the vortex forming groove 82 flows between the groove outer surface 82a and the groove inner surface 82b while moving from the groove bottom surface 82c of the maximum groove depth WN of the hole center line s of the liquid introduction hole 80 toward the plate surface 74A of the second guide plate 74. The liquid flowing between the groove outer surface 82a and groove inner surface 82b of the vortex forming groove 82 flows out (sprays) from the vortex forming groove 82 toward the inner surface 72b of the second guide tube portion 72 at the position of the hole center line t of the liquid introduction hole 79, into the second guide tube portion 72 (gas-liquid mixing chamber τ2) between one of the tube ends 72A and the second guide plate 74, and flows along the inner surface 72b of the second guide tube portion 72. The vortex forming groove 82 causes the liquid flowing out from the liquid introduction hole 80 to flow (spray) toward the inner surface 72b of the second guide tube portion 72 and into the second guide tube portion 72 (into the gas-liquid mixing chamber τ2), causing the liquid to flow along the inner surface 72b of the second guide tube portion 72.

[0103] The liquid flowing out from each vortex forming groove 81, 82 into the second guide tube portion 72 swirls in the same direction along the inner surface 72b of the second guide tube portion 72, centered on the tube center line a of the tube main body 1 (second guide tube portion 72), and is caused to flow by the second guide plate 74 (plate surface 74A) from the vortex forming body 3 (inside the first and second guide tube portions 71, 72) toward the partition main body 51 (partition body 2), forming (generating) a vortex flow around the tube center line of the tube main body 1 in the liquid filled (sufficient) in the gas-liquid mixing chamber τ2.

[0104] The vortex forming body 3 receives liquid that has flowed into the inflow space (inflow chamber τ3) from the inlet 13 (flows into each liquid introduction hole 79, 80), and causes the liquid to flow out (squirt) into the gas-liquid mixing chamber τ2 (flows out of each liquid introduction hole 79, 80 into the gas-liquid mixing chamber τ2), forming (generating) a vortex flow around the center line a of the cylindrical main body in the liquid in the gas-liquid mixing chamber τ2.

[0105] The vortex forming body 3 includes a first guide tube portion disposed in the inflow space in close contact with the inner circumferential surface of the tube main body, a second guide tube portion disposed concentrically with the tube main body (first guide tube portion) and disposed within the first guide tube portion with one tube end facing the blocking body, a first guide plate disposed between the first and second guide tube portions and blocking the space between the first and second guide tube portions, a second guide plate blocking the other tube end of the second guide tube portion, a pair of first and second liquid introduction flow paths (first and second liquid introduction holes 79, 80) into which liquid that has flowed into the inflow space (inflow chamber) from the inlet is introduced, a first vortex forming flow path (vortex forming groove 81) disposed in the second guide plate and communicating with the first liquid introduction flow path, and a second guide plate disposed in the second guide plate. and a second vortex forming flow passage (vortex forming groove 82) positioned above the first vortex forming flow passage and connected to the second liquid introduction flow passage, the first vortex forming flow passage flows (spouts) the liquid flowing out from the first liquid introduction flow passage into the second guide tube portion toward the inner circumferential surface of the second guide tube portion, causing the liquid to flow along the inner circumferential surface of the second guide tube portion, the second vortex forming flow passage flows (spouts) the liquid flowing out from the second liquid introduction flow passage into the second guide tube portion toward the inner circumferential surface of the second guide tube portion, causing the liquid to flow along the inner circumferential surface of the second guide tube portion, and the first and second vortex forming flow passages flow the liquid in the same direction along the inner circumferential surface of the second guide tube portion, forming (generating) a vortex flow around the tube center line of the tube main body in the liquid in the gas-liquid mixing chamber.

[0106] The third sphere 4Z (first floating body 4), second sphere 5Y (second floating body) and first sphere 6X (third floating body) arranged (stored) in the gas-liquid mixing chamber τ2 float (move / flow) within the gas-liquid mixing chamber τ2 due to the vortex flow formed in the liquid in the gas-liquid mixing chamber τ2, as shown in Figure 33, and agitate the liquid in the gas-liquid mixing chamber τ2. As shown in Fig. 33, the third sphere 4Z, the second sphere 5Y and the first sphere 6X are moved around the cylinder center line a of the cylinder body 1 in the gas-liquid mixing chamber τ2 (in the gas-liquid mixing chamber τ2 between the partition body 51 and the second guide plate 74) while rotating, and the surfaces 4a, 5a and 6a (spherical surfaces) of the spheres 4Z, 5Y and 6X come into contact with the liquid of the vortex flow, stirring (disturbing) the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2. The spheres 4Z, 5Y and 6X are formed, for example, of materials having the same density, and are formed as spheres of different sizes (different volumes). The third sphere 4Z (first floating body) is formed into the largest shape (largest volume) and has the heaviest mass among the spheres 4Z, 5Y, and 6X, the second sphere 5Y (second floating body) is formed into the second largest shape (second largest size) and has the second heaviest mass among the spheres 4Z, 5Y, and 6X, and the first sphere 6X is formed into the smallest shape (smallest volume) and has the lightest mass among the spheres 4Z, 5Y, and 6X (same below). As shown in Fig. 33, the third sphere 4Z (first floating body) is moved around the cylinder center line a of the cylinder main body 1 mainly in the gas-liquid mixing chamber τ2 on the second guide plate 74 side (vortex forming body 3 side) by the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2 while rotating, disturbing the vortex flow and stirring the liquid in the gas-liquid mixing chamber τ2. The third sphere 4Z (first floating body) rotates (spins) around the sphere center u of the third sphere 4Z while floating (moving / flowing) in the gas-liquid mixing chamber τ by the liquid flowing into each of the through holes 84, disturbing the vortex flow and stirring the liquid in the gas-liquid mixing chamber τ2. As shown in Figure 33, the first sphere 6X (third floating body) is caused to move and rotate mainly in the gas-liquid mixing chamber τ2 on the partition body 51 side (partition body 2 side) around the cylindrical center line a of the cylindrical body 1 due to the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2, disrupting the vortex flow and stirring the liquid in the gas-liquid mixing chamber τ2. As shown in Fig. 33, the second sphere 5Y (second floating body) is moved around the cylinder center line a of the cylinder main body 1 mainly in the gas-liquid mixing chamber τ2 between the third sphere 4Z and the first sphere 6X while rotating due to the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2, disturbing the vortex flow and stirring the liquid in the gas-liquid mixing chamber τ2. The second sphere 5Y (second floating body 5) rotates (spins) around the sphere center λ of the second sphere 5Y while floating (moving / flowing) in the gas-liquid mixing chamber τ due to the liquid flowing into each recess 85 caused by the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2, stirring the liquid in the gas-liquid mixing chamber τ2. Each sphere 4Z, 5Y, 6X disturbs the vortex flow formed (generated) in the gas-liquid mixing chamber τ2 between the partition body 51 (partition body 2) and the vortex forming body 3 in the direction A of the cylinder center line a of the cylinder body 89, thereby agitating the liquid in the gas-liquid mixing chamber τ2. Each sphere 4Z, 5Y, 6X does not pass through each outflow hole 52 (each mesh ε) and does not get stuck in each vortex forming groove 81, 82 (between the groove outer surface and the groove inner surface), but is allowed to float (move) within the gas-liquid introducing chamber τ2 between the partition body 51 and the second guide plate 74 (first guide flat plate 73) due to the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2.

[0107] The gas (air) in the liquid in the gas-liquid mixing chamber τ2 is precipitated from the liquid by the vortex flow formed in the liquid in the gas-liquid mixing chamber τ2 by the vortex forming body 3 and the agitation of the liquid by the first to third spheres 4Z, 5Y, 6X, and is crushed (sheared) to become a large amount of microbubbles and ultrafine bubbles. The microbubbles and ultrafine bubbles are mixed and dissolved in the liquid flowing in the gas-liquid mixing chamber τ2, and become a bubble liquid (bubble water) in which a large amount of microbubbles and a large amount of ultrafine bubbles are mixed and dissolved. The bubble liquid (bubble water) flows through the gas-liquid mixing chamber τ2 and is sprayed (ejected) from each outlet hole 52 of the partition body 51 (partition body 2) into the outlet chamber τ3, and flows into the flow path hole 42 of the cover member 18 from the outlet port 14. The bubble liquid (bubble water) that flows into the flow path hole 42 of the cover member 18 flows through the flow path hole 42 and flows out of the bubble liquid generating device X. In this way, in the bubble liquid generating device X, a vortex flow is formed (generated) in the liquid in the gas-liquid mixing chamber τ2, and the vortex flow causes each of the spheres 4Z, 5Y, 6X (each type of floating body 4, 5, 6) to float (move / flow) within the gas-liquid mixing chamber τ2, and the third sphere 4Z (first floating body 4) and the second sphere 5Y (second floating body) are caused to float and rotate, vigorously stirring the liquid in the gas-liquid mixing chamber τ2, making the liquid flowing through the gas-liquid mixing chamber τ2 a turbulent flow, and the turbulent flow causes the gas (air) in the liquid to separate and be crushed (sheared) into a large amount of microbubbles and ultra-fine bubbles.

[0108] In the bubble liquid generator X, as shown in Fig. 34, multiple floating bodies of the same size (multiple floating bodies formed in shapes of different sizes) may be arranged (stored) in the gas-liquid mixing space τ2 so as to be freely movable (free to move). The multiple floating bodies (each of the multiple floating bodies) are formed into spheres of the same spherical diameter. Each of the multiple floating bodies is composed of one of the first sphere, the second sphere, or the third sphere. As shown in FIG. 34, each of the plurality of floating bodies is a sphere having the same spherical diameter, and is composed of, for example, any one of a first sphere 4X, a second sphere 4Y, and a third sphere 4Z. In Fig. 34, the first sphere 4X, the second sphere 4Y, and the third sphere 4Z are arranged (stored) in the gas-liquid mixing chamber τ2 so as to be freely movable (free to move), and as explained in Fig. 33, the vortex flow formed in the liquid in the gas-liquid mixing chamber τ2 by the vortex forming body 3 causes the spheres to rotate and move about the center line a of the cylinder body 1, and the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2 causes the spheres to precipitate out of the liquid and be crushed (sheared) to become a large amount of microbubbles and ultrafine bubbles. The microbubbles and ultrafine bubbles are mixed and dissolved in the liquid flowing in the gas-liquid mixing chamber τ2, and become a bubbly liquid (bubble water) in which a large amount of microbubbles and a large amount of ultrafine bubbles are mixed and dissolved. As explained in Figure 33, the second sphere 4Y and the third sphere 4Z (first floating body) rotate (spin) around the sphere center u of each sphere 4Y, 4Z while floating within the gas-liquid mixing chamber τ2 due to the vortex flow formed (generated) in the gas-liquid mixing chamber τ2, thereby stirring the liquid (vortex flow) in the gas-liquid mixing chamber τ2.

[0109] The bubble liquid generating nozzle according to the present invention will be described with reference to Figs. 35 to 45, the same reference numerals as those in FIGS. 1 to 34 denote the same members and configurations, and detailed description thereof will be omitted.

[0110] 35 to 45, the bubble liquid generating nozzle Y includes a cylindrical main body 89, a vortex forming body 3, and a plurality of types of floating bodies (moving bodies) having different sizes.

[0111] 35 to 45 , the cylindrical main body 89 has a cylindrical body 90, a blocking body 91 that blocks one cylindrical end of the cylindrical body 90, an inflow port 13, and a plurality of injection holes 92. The cylindrical main body 89 forms an inflow space α1 into which liquid flows in from the inflow port 13.

[0112] As shown in FIGS. 35 to 41, the cylindrical body 90 is configured to include a cylindrical member 17, a nozzle member 93 (first cover member), and a cover member 19 (second cover member).

[0113] The nozzle member 93 (lid member / first lid member) has a cylindrical portion 94, a cylindrical hole 95 (lid inlet hole), a female thread portion 96, and a blocking plate 97, as shown in FIGS.

[0115] 39 and 40 , the cylindrical hole 95 is formed in the cylindrical portion 94. The cylindrical hole 95 is formed in a circular shape and is disposed concentrically with the cylindrical portion 94. The cylindrical hole 95 penetrates the cylindrical portion 94 in the direction A of the cylindrical center line a of the cylindrical portion 94 and opens to each cylindrical end 94A, 94B of the cylindrical portion 94.

[0116] As shown in FIG. 40, the female screw portion 96 is formed on the inner circumference (inner peripheral surface) of the cylindrical hole 95 (cylindrical portion 94).

[0117] As shown in Figures 39 and 40, the blocking plate 97 (blocking body) is formed as a circular flat plate (circular flat plate) having a plate thickness. The blocking plate 97 has a plate surface 97A (plate surface plane) and a plate back surface 97B (plate back plane) in the plate thickness direction. The blocking plate 97 is arranged concentrically with the tubular portion 94 (cylindrical member 17) of the nozzle member 93. The blocking plate 97 blocks one of the tubular ends 94A of the tubular portion 94 of the nozzle member 93 by abutting the plate back surface 97B of the blocking plate 97 against one of the tubular ends 94A of the tubular portion 94 (nozzle member 93). The blocking plate 97 (blocking body) is formed integrally with the tubular portion 94 of the nozzle member 93.

[0118] In the bubble liquid generating nozzle Y, the cylindrical member 17 is arranged concentrically with the nozzle member 93 and the cover member 19, as shown in Fig. 39 and Fig. 41. The cylindrical member 17 is inserted into a cylindrical hole 95 of the nozzle member 93 (first cover member) from one cylindrical end 24A of the cylindrical portion 24 (cylindrical member 17), one male screw portion 27 (first male screw portion) of the cylindrical member 17 is screwed (screwed into) into a female screw portion 96 of the nozzle member 93, and one cylindrical end 24A of the cylindrical portion 24 (cylindrical member 17) is abutted against a plate back surface 97B of a blocking plate 97 (blocking body 91) of the nozzle member 93, and is connected to the nozzle member 93. The cylindrical member 17 and the nozzle member 93 are connected airtight via a seal ring 98. The nozzle member 93 is fitted from the other cylinder end 94B of the cylinder portion 94 onto one cylinder end 24A of the cylinder portion 24 (cylindrical member 17), and is connected to the cylindrical member 17 by screwing the male screw portion 27 of the cylindrical member 17 into the female screw portion 96. The nozzle member 93 is connected to the cylindrical member 17 by screwing the male screw portion 27 of the cylindrical member 17 into the female screw portion 96 and abutting the plate back surface 97B of the blocking plate 97 against one cylinder end 24A of the cylinder portion 24. The nozzle member 93 is connected to the cylindrical member 17 by screwing the male screw portion 27 of the cylindrical member 17 into the female screw portion 96 and abutting the other cylinder end 34B against the flange portion 26. The blocking plate 97 of the nozzle member 93 is a blocking body 91.

[0119] In the bubble liquid generating nozzle Y, the cylindrical member 17 is connected to the cover member 19 in the same manner as described with reference to FIGS.

[0120] 38 and 41, the cylinder main body 89 is formed by connecting the cylindrical member 17, the nozzle member 93 and the cover member 19, and the cylinder portion 24 of the cylindrical member 17, the cylinder portion 94 of the nozzle member 93 and the cylinder portion 34 of the cover member 19 form a cylinder body 90. The cylinder body 90 is formed by connecting the cylindrical member 17, the nozzle member 93 and the cover member 19, and is formed by the cylinder portion 24 of the cylindrical member 17, the cylinder portion 94 of the nozzle member 93 and the cylinder portion 34 of the cover member 19. One cylinder end 24A of the cylinder portion 24 (cylindrical member 17) becomes one cylinder end of the cylinder body 90 when the cylindrical member 17, the nozzle member 93 and the cover member 19 are connected.

[0121] As shown in Figures 38 and 41, when the cylindrical member 17, nozzle member 93 and cover member 19 are connected, the cylindrical body 90 (cylindrical portion 24 of the cylindrical member 17 and cylindrical portion 34 of the cover member 19) is closed by the closing plate 97 of the nozzle member 93 and the closing plate 37 of the cover member 19, forming an inflow space α1 inside the cylindrical main body 89. The inflow space α1 is formed by an inflow hole β1 extending in the direction A of the cylindrical center line a of the cylindrical main body 89 (cylindrical body 90). The inflow hole β1 is composed of the cylindrical hole 25 of the cylindrical member 17, the cylindrical hole 35 (small diameter hole portion 40) of the cover member 19 and the conical hole 45 of the cover member 19. The inflow hole β1 blocks each hole end (the hole end of the tubular hole 25 of the cylindrical member 17 and the hole end of the conical hole 45 of the cover member 19) to form an inflow space α1 between the blocking plate 97 of the nozzle member 93 and the blocking plate 37 of the cover member 19 inside the cylindrical body 89. As shown in FIGS. 38 and 41, the inflow space α1 is formed extending in the direction A of the cylinder center line a of the cylinder main body 89 between the blocking body 91 and the inflow port 13 (the blocking plate 37 of the cover member 19).

[0122] As shown in Fig. 38 and Fig. 41, a plurality of injection holes 92 are formed in the blocking body 91 (blocking plate 97 of the nozzle member 93). Each injection hole 92 is arranged on each circle CX, CY, CZ of different radii centered on the cylinder center line a (plate center line of the blocking body 91) of the cylinder main body 89. Each injection hole 92 is arranged with the hole center line b of each injection hole 92 parallel to the cylinder center line a of the cylinder main body 89. Each injection hole 92 penetrates the blocking body 91 (blocking plate 97 of the nozzle member 93) in the direction A of the cylinder center line a of the cylinder main body 89 and communicates with the inflow space α1 (space). Each injection hole 92 is formed as a circular hole. Each injection hole 92 has a circular opening area Sq with a hole diameter dφ, opens on the plate back surface 91B of the blocking body 91, and communicates with the inflow space α1.

[0123] As shown in Figures 38 and 42, the vortex forming body 3 is disposed in the inflow space α1 between the obstruction body 91 and the inlet 13 in the direction A of the cylinder center line a of the cylinder main body 89, and forms (partitions) a gas-liquid mixing chamber τ2 between the obstruction body 91 (obstruction plate 97 of the nozzle member 93). The vortex forming body 3 is disposed in the inflow space α1 (inflow hole β1) between the obstruction body 91 and the inlet 13 with a gap between the vortex forming body 3 (second guide plate 74) and the obstruction body 91 in the direction A of the cylinder center line a of the cylinder main body 89.

[0124] As described in Figure 7, the vortex forming body 3 is arranged in the inflow space α1 (inflow hole β1) between the blocking plate 37 of the cover member 19 and the blocking body 91 in the direction A of the cylinder center line a of the cylinder main body 89, and forms (partitions) an inflow chamber τ3 between the blocking plate 37 of the cover member 19.

[0125] The vortex forming body 3 (first and second cylindrical guide portions 71, 72) is arranged concentrically with the cylindrical body 89 in the inflow space α1 (inflow hole β1) between the obstruction body 91 and the inflow port 13, as shown in FIGS. As shown in Figures 38 and 41, the vortex forming body 3 is arranged in the direction A of the tube center line a of the tube main body 89, concentrically with the tube main body 89, in the inflow space α1 (inflow hole β1) between the blocking plate 37 (inlet 13) of the cover member 19 and the blocking body 91.

[0126] As shown in Figures 38, 42 and 43, the vortex generating body 3 is disposed in the inflow space α1 (inflow hole β1) with one cylinder end 71A (vortex generating grooves 81, 82) of the first guide cylinder portion 71 facing the obstruction body 91.

[0133] In the bubble liquid generating nozzle Y, the third floating body 6 is composed of any one of the first sphere 6X, the second sphere 6Y, and the third sphere 6Z, as explained in FIG. 30 and FIG. In the bubble liquid generating nozzle Y, each of the spheres 6X, 6Y, 6Z of the third floating body 6 is formed in a shape (a sphere having a spherical diameter larger than the opening area Sq of the injection hole 92) larger than the injection hole 92 (the opening area Sq of the injection hole 92), but has the same configuration as each of the spheres 6X, 6Y, 6Z of the third floating body 6 of the nozzle generating device X.

[0134] In the bubble liquid generating nozzle Y, each of the three types of floating bodies 4, 5, 6 (each of the first to third floating bodies / each of the multiple types of floating bodies) is composed of one of the first spheres 4X, 5X, 6X, the second spheres 4Y, 5Y, 6Y, and the third spheres 4Z, 5Z, 6Z, as shown in Figures 38 and 44, and one or more are arranged (stored) in the gas-liquid mixing chamber τ2 so as to be freely movable (free to move). One or more spheres (floating bodies) are arranged (stored) in the gas-liquid mixing chamber τ2. In the bubble liquid generating nozzle Y, three types of floating bodies 4, 5, 6 (each type of floating body) are floated (moved) between the obstruction body 91 (obstruction plate 97 of the nozzle member 93) and the vortex forming body 3 (first guide plate 73, second guide plate 74) within the gas-liquid mixing chamber τ2, as shown in Figures 38 and 44. Of the three types of floating bodies 4 to 6 (each type of floating body) of the bubble liquid generating nozzle Y, the first spheres 4X, 5X, 6X, the second spheres 4Y, 5Y, 6Y, and the third spheres 4Z, 5Z, 6Z arranged (stored) in the gas-liquid mixing chamber τ2 are floated (moved) between the obstruction body 91 (obstruction plate 97 of the nozzle member 93) and the vortex forming body 3 (first guide plate 73, second guide plate 74) by the liquid flowing through the gas-liquid inflow chamber τ2.

[0135] In the bubble liquid generating nozzle Y, three types of floating bodies 4, 5, and 6, for example, one or more third spheres 4Z (first floating bodies 4), one or more second spheres 5Y (second floating bodies 5), and one or more first spheres 6X (third floating bodies 6), are arranged (stored) in the gas-liquid mixing chamber τ2 so that they can move freely (be movable) as shown in Figure 44.

[0136] 36 to 38 and 42 to 44, the bubble liquid generating nozzle Y is connected to a liquid supply source (not shown), and liquid (e.g., water) flows from the liquid supply source into the inflow space σ (inflow hole β) of the tube main body 89. The bubble liquid generating nozzle Y connects the boss portion 38 (flow path hole 42) of the cover member 19 (second cover member) to the liquid supply source, and liquid from the liquid supply source is supplied to the flow path hole 42 of the cover member 19. The liquid supplied to the flow path hole 42 of the cover member 19 flows from the inlet 13 into the inflow chamber τ3 (inflow space α / inflow hole β).

[0137] As shown in Figures 38, 42 to 44, the liquid that has flowed into the inflow chamber τ3 (inflow space α / inflow hole β) fills (fills) the inflow chamber τ3, and also flows into each liquid introduction hole 79, 80 from the other cylindrical ends 77B, 78B of each liquid introduction cylindrical portion 77, 78. The liquid that has flowed into each liquid introduction hole 79, 80 flows through each liquid introduction hole 79, 80 along with the flow of liquid from the inlet 13 into the inflow chamber τ3, and flows out into each vortex forming groove 81, 82 of the vortex forming body 3, filling (filling) the gas-liquid inflow chamber τ2 and the outflow chamber τ1 (inflow space α / inflow hole β). As shown in Figures 38, 43 and 44, when the inflow space α (inflow chamber τ3, gas-liquid mixing chamber τ2 and outflow chamber τ1) is filled (full) with liquid, the liquid flowing through each liquid introduction hole 79, 80 flows out (spouts) into each vortex forming groove 81, 82 of the vortex forming body 3.

[0138] In the bubble liquid generating nozzle Y, the liquid flowing out (sprayed) from each liquid introduction hole 79, 80 (liquid introduction flow path) into each vortex forming groove 81, 82 (vortex forming flow path) flows out (sprayed) from the vortex forming grooves 81, 82 toward the inner surface 72b of the second guide tube portion 72, into the second guide tube portion 72 (inside the gas-liquid mixing chamber τ2) between one of the tube ends 72A and the second guide plate 74, as described in Figures 8 and 20, and flows along the inner surface 72b of the second guide tube portion 72 (see Figures 43 and 44).

[0139] In the bubble liquid generating nozzle Y, the liquid flowing out from each vortex forming groove 81, 82 into the second guide tube portion 72 swirls in the same direction along the inner surface 72b of the second guide tube portion 72, centered on the tube center line a of the tube main body 89 (second guide tube portion 72), as shown in Figures 43 and 44, and is caused to flow from the vortex forming body 3 (inside the first and second guide tube portions 71, 72) toward the partition main body 51 (partition body 2) by the second guide plate 74 (plate surface 74A), forming (generating) a vortex flow around the tube center line a of the tube main body 89 in the liquid filled (sufficient) in the gas-liquid mixing chamber τ2.

[0140] The third sphere 4Z (first floating body 4), second sphere 5Y (second floating body) and first sphere 6X (third floating body) arranged (stored) in the gas-liquid mixing chamber τ2 float (move / flow) within the gas-liquid mixing chamber τ2 due to the vortex flow formed in the liquid in the gas-liquid mixing chamber τ2, as shown in Figure 44, and agitate the liquid in the gas-liquid mixing chamber τ2. As shown in FIG. 44, the third sphere 4Z, the second sphere 5Y, and the first sphere 6X are caused to move in the gas-liquid mixing chamber τ2 ( Occlusion plate 97 The spheres 4Z, 5Y, 6X rotate and float (move while rotating) in the gas-liquid mixing chamber τ2 between the first guide plate 74 and the second guide plate 74, and by contacting the surfaces 4a, 5a, 6a (spherical surfaces) of the spheres 4Z, 5Y, 6X with the liquid of the vortex flow, they agitate (disturb the vortex flow) the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2. As shown in Figure 44, the third sphere 4Z (first floating body) is caused to move while swirling mainly in the gas-liquid mixing chamber τ2 on the second guide plate 74 side (vortex forming body 3 side) around the cylinder center line a of the cylinder main body 89 due to the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2, disturbing the vortex flow and agitating the liquid in the gas-liquid mixing chamber τ2. The third sphere 4Z (first floating body) is caused to move while swirling mainly in the gas-liquid mixing chamber τ2 on the second guide plate 74 side (vortex forming body 3 side) due to the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2, disturbing the vortex flow and agitating the liquid in the gas-liquid mixing chamber τ2. τ2 While floating (moving / flowing), the third sphere 4Z rotates (spins) about the spherical center u of the third sphere 4Z, disturbing the vortex flow and agitating the liquid in the gas-liquid mixing chamber τ2. As shown in Figure 44, the first sphere 6X (third floating body) is caused to move and swirl mainly in the gas-liquid mixing chamber τ2 on the obstruction body 12 side (the obstruction plate 97 side of the nozzle member 93) around the cylindrical center line a of the cylindrical main body 89 due to the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2, disrupting the vortex flow and stirring the liquid in the gas-liquid mixing chamber τ2. As shown in Figure 44, the second sphere 5Y (second floating body) is caused to move while rotating mainly in the gas-liquid mixing chamber τ2 between the third sphere 4Z and the first sphere 6X around the cylindrical center line a of the cylindrical main body 89 due to the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2, disturbing the vortex flow and agitating the liquid in the gas-liquid mixing chamber τ2. The second sphere 5Y (second floating body 5) is caused to move while rotating mainly in the gas-liquid mixing chamber τ2 between the third sphere 4Z and the first sphere 6X around the cylindrical center line a of the cylindrical main body 89 due to the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2, disturbing the vortex flow and agitating the liquid in the gas-liquid mixing chamber τ2. τ2 The second sphere 5Y rotates (spins) about the sphere center λ of the second sphere 5Y while floating (moving / flowing), thereby agitating the liquid in the gas-liquid mixing chamber τ2. Each of the spheres 4Z, 5Y, 6X disturbs the vortex flow formed (generated) in the gas-liquid mixing chamber τ2 between the obstruction body 91 and the vortex forming body 3 in the direction A of the cylinder center line a of the cylinder main body 89, thereby agitating the liquid in the gas-liquid mixing chamber τ2. Each sphere 4Z, 5Y, and 6X is an injection hole. 92 The gas flows through the vortex flow generated in the liquid in the gas-liquid mixing chamber τ2 without passing through the vortex flow generated in the liquid in the gas-liquid mixing chamber τ2, without getting stuck in the vortex flow generated in the liquid in the gas-liquid mixing chamber τ2, and without getting stuck in the vortex flow generated in the liquid in the gas-liquid mixing chamber τ2. Occlusion plate 97 and the second guide plate 74 (first guide plate 73) and the gas / liquid introducing chamber τ2 between them.

[0141] The gas (air) in the liquid in the gas-liquid mixing chamber τ2 is precipitated from the liquid and crushed (sheared) by the vortex flow formed in the liquid in the gas-liquid mixing chamber τ2 by the vortex forming body 3 and the stirring of the liquid by the movement and rotation of the first to third spheres 4Z, 5Y, 6X, and becomes a large amount of microbubbles and ultrafine bubbles. The microbubbles and ultrafine bubbles are mixed and dissolved in the liquid flowing in the gas-liquid mixing chamber τ2, and become a bubble liquid (bubble water) containing a large amount of microbubbles and ultrafine bubbles. The bubble liquid (bubble water) flows through the gas-liquid mixing chamber τ2 and is sprayed (ejected) from each outlet hole 52 of the partition body 51 (partition body 2) into the outlet chamber τ3, and is sprayed from each injection hole 92 (nozzle hole) to the outside of the bubble liquid generating nozzle Y.

[0142] In this way, in the bubble liquid generating nozzle Y, a vortex flow is formed (generated) in the liquid in the gas-liquid mixing chamber τ2, and the vortex flow causes each of the spheres 4Z, 5Y, 6X (each type of floating body 4, 5, 6) to float (move / flow) within the gas-liquid mixing chamber τ2, and the third sphere 4Z (first floating body 4) and the second sphere 5Y (second floating body) are caused to float and rotate, vigorously stirring the liquid in the gas-liquid mixing chamber τ2, making the liquid flowing through the gas-liquid mixing chamber τ2 a turbulent flow, and the turbulent flow causes the gas (air) in the liquid to precipitate and be crushed (sheared), resulting in a large amount of microbubbles and ultra-fine bubbles.

[0143] In the bubble liquid generating nozzle Y, as shown in Fig. 45, multiple floating bodies of the same size (multiple floating bodies formed in the same shape and size) may be arranged (stored) in the gas-liquid mixing space τ2 so as to be freely movable (movable). The multiple floating bodies (each of the multiple floating bodies) are formed into spheres of the same spherical diameter. Each of the multiple floating bodies is composed of one of the first sphere, the second sphere, or the third sphere. As shown in FIG. 45, each of the plurality of floating bodies is a sphere having the same spherical diameter, and is composed of, for example, any one of a first sphere 4X, a second sphere 4Y, and a third sphere 4Z. In Fig. 45, the first sphere 4X, the second sphere 4Y, and the third sphere 4Z are arranged (stored) in the gas-liquid mixing chamber τ2 so as to be freely movable (free to move), and as explained in Fig. 44, the vortex flow formed in the liquid in the gas-liquid mixing chamber τ2 by the vortex forming body 3 causes the spheres to move while rotating around the center line a of the cylinder body 89, and the vortex flow formed (generated) in the liquid in the gas-liquid mixing chamber τ2 causes the spheres to precipitate out of the liquid and be crushed (sheared) to become a large amount of microbubbles and ultrafine bubbles. The microbubbles and ultrafine bubbles are mixed and dissolved in the liquid flowing in the gas-liquid mixing chamber τ2, and become a bubbly liquid (bubble water) in which a large amount of microbubbles and a large amount of ultrafine bubbles are mixed and dissolved. As explained in Figure 44, the second sphere 4Y and the third sphere 4Z (first floating body) rotate (spin) around the sphere center u of each sphere 4Y, 4Z while floating within the gas-liquid mixing chamber τ2 due to the vortex flow formed (generated) in the gas-liquid mixing chamber τ2, thereby stirring the liquid (vortex flow) in the gas-liquid mixing chamber τ2.

[0144] In the bubble liquid generating device X and the bubble liquid generating nozzle Y, each type of floating body may be formed into a triangular pyramid, a square pyramid, a cylinder, a square prism, a cylinder, or the like in addition to being configured as a sphere.
