- the “fine bubble generating device” proposed in Patent Document 3 not only has a complicated configuration as described above, but also “a device that generates vortex and shear by stirring raw water”. However, it is unclear whether it is an apparatus that “mixes and dissolves microbubbles that become microbubbles”.

- this bubble generator 100 produces
- the bubble generator 100 includes an upstream main body 10 provided with a first flow path 11 that narrows toward the downstream side, and a large number of passages housed in the first flow path 11.
- the diverting piece 30 is provided with a liquid hole 31 and the downstream main body 20 is provided with a second flow path 21 that is attached to the upstream main body 10 and expands toward the downstream side.
- the bubble generator 100 is configured so that the liquid that has flowed into the first flow path 11 of the upstream main body 10 is smoothly fed into the second flow path 21 of the downstream main body 20.
- the downstream end of the second channel 21 is opposed to the upstream end of the second flow path 21.
- the bubble generator 100 includes a downstream main body positioned on the lower side in the drawing in the liquid fed from the pressure liquid supply member 210 to the upstream main body 10 side. During the feeding from 20 to the second flow path 21, micro bubbles are generated inside, and the micro bubbles are mixed into the liquid discharged from the second flow path 21. Note that the bubble generator 100 shown in FIG. 1 is upside down from the bubble generator 100 shown in FIG.
- microbubbles are generated as follows. First, the liquid fed into the upstream main body 10 is discharged into the first flow path 11 while being diverted by flowing into the respective liquid flow holes 31 of the diversion piece 30. Since the first flow path 11 is narrowed toward the downstream side, the liquid discharged into the first flow path 11 is sent toward the downstream side while being compressed. Since the downstream end of the first flow path 11 is opposed to the upstream end of the second flow path 21 formed in the downstream main body 20, the liquid flows from the first flow path 11 to the second flow. It flows into the path 21. Since the second flow path 21 is widened toward the downstream side, the pressure of the liquid suddenly drops at the downstream end thereof.
- the liquid is not only subjected to various shear stresses but also pressurized and released, so that cavitation occurs in the liquid.
- each of these forces may cause a flow of a complicated shape in the bubble generator 100, so that these forces themselves are not only relatively large, but also the first flow path 11 and the second flow. Since it is hung or released within an extremely short path in the path 21, that is, within a short time, when the gas component dissolved in the liquid appears as bubbles by cavitation, it is extremely minute. Bubbles, that is, microbubbles.
- the use of the bubble generator 100 causes cavitation in the liquid for the following reason.
- this bubble generator 100 when the liquid passes through the opening 11a of the first flow path 11 of the upstream main body 10, a gas axis (vacuum axis) is formed at the center of the liquid flow by the action of the swirling flow. .
- the liquid when the liquid is discharged from the opening 21a of the downstream main body 20 to the second flow path 21, it is considered that the liquid flows in the central portion by the surrounding liquid wall. Therefore, it is considered that the liquid to be drawn to the gas shaft side collides with the liquid ejected radially from the opening 21a, and the gas on the gas shaft is sheared to generate micro bubbles. .
- microbubbles In general, vapor and bubbles generated by cavitation are absorbed into the liquid again within a short time, but the bubbles generated in the bubble generator 100 according to the present invention are microbubbles called microbubbles. It is not absorbed into the liquid again within a short time due to its surface tension or the like. In other words, microbubbles, that is, microbubbles remain in the liquid discharged from the second flow path 21, and if this liquid is used as shower water from the shower nozzle 200, for example, Hair washing and body washing can be performed with high detergency.
- the bubble generator 100 it is possible to generate extremely small bubbles and use them for shower nozzles 200, faucets for tap water, pipes for bathrooms, water tanks and dishwashers, and gardening. It is suitable for watering showers.
- the means taken by the invention according to claim 2 is the bubble generator 100 according to claim 1 described above.
- the surface roughness Ra of at least one of the contact surface 15 of the upstream main body 10 and the contact surface 25 of the downstream main body 20 that are in contact with each other is set to 0.2 to 6.3, The outside air can be introduced into the inside through a minute gap between the contact surfaces 15 and 25.

- the surface roughness Ra of at least one of the contact surface 15 of the upstream main body 10 and the contact surface 25 of the downstream main body 20 that are in contact with each other is set to 0.2. Since ⁇ 6.3, a fine gap is formed between the contact surfaces 15 and 25. Therefore, when a negative pressure is generated in the supplied liquid when the liquid supplied to the upstream main body 10 is supplied to the downstream main body 20, the contact surface 15 is generated by the negative pressure. -Outside air will be introduced into the bubble generator 100 from the minute gaps between 25.
- the surface roughness Ra of at least one of the contact surface 15 of the upstream main body 10 and the contact surface 25 of the downstream main body 20 must be 0.2 to 6.3. It is as follows. First, if the surface roughness RA of the contact surface 15 of the upstream main body 10 or the contact surface 25 of the downstream main body 20 is smaller than 0.2, the clearance between the contact surfaces 15 and 25 is small and the introduction of outside air is reduced.

- the contact surface 15 of the upstream main body 10 and the contact surface 25 of the downstream main body 20 are not necessarily required. However, if the surface roughness Ra of both the abutment surface 15 of the upstream main body 10 and the abutment surface 25 of the downstream main body 20 is set to 0.2 to 6.3, generation control of microbubbles described later is performed. It is natural that it becomes easy.

- the downstream end of the first flow path 11 and the upstream end of the second flow path 21 are once opened in the space 40.
- the fact that the downstream end of the first flow path 11 is opened in the space 40 generates a negative pressure due to the venturi effect in the liquid flowing out from the downstream end of the first flow path 11. It is.

- the outside air intake member 50 communicates with the space 40 via the intake 51, and a negative pressure is generated in the space 40 when liquid flows out from the downstream end of the first flow path 11. Therefore, while the bubble generator 100 is functioning, the negative pressure in the space 40 is applied to the outside air intake member 50 via the intake port 51. When this negative pressure is applied to the outside air intake member 50, the outside air intake member 50 introduces outside air into the space 40 through the inlet 51, and this outside air is minutely generated by the liquid flow in the space 40.

At least one surface roughness Ra is set to 0.2 to 6.3. For this reason, a fine gap is formed between the contact surfaces 15 and 25. Therefore, when a negative pressure is generated in the liquid supplied to the downstream main body 20 when the liquid supplied to the upstream main body 10 is supplied to the downstream main body 20, the negative pressure causes the space between the contact surfaces 15 and 25. The outside air is introduced into the bubble generator 100 through the minute gap.
- a packing 16 for preventing liquid leakage is interposed between the contact surfaces 15 and 25, and this packing is provided. 16 has an inverted U-shaped cross section. This packing 16 is easy to allow the introduction of outside air from the gap between the contact surfaces 15 and 25, and conversely, it is easy to prevent liquid leakage due to liquid pressure from the inside of the bubble generator 100.

- a spring 53 is disposed on the bubble generator 100 side of the valve body 52, and the spring 53 always biases the valve body 52 to the opposite side of the bubble generator 100. Further, the urging force of the spring 53 is adjusted by an adjusting screw 55 that protrudes outside and is integrated with the valve body 52. Further, the outside air intake member 50 allows the outside and the inside of the space 40 to communicate with each other through the periphery of the adjustment screw 55 when the valve body 52 is not in contact with the valve seat 54.
- the outside air intake member 50 is in a state in which outside air can be sufficiently taken in even if the negative pressure in the space 40 is not large. If the urging force of 53 is increased, outside air cannot be taken in unless the negative pressure in the space 40 is increased. Of course, even when the outside air is not taken in by the outside air intake member 50, that is, when the microbubbles are not generated, it is needless to say that the “miniature bubbles” themselves are generated by the basic structure of the bubble generator 100. Yes.
- the outside air intake member 50 also has a “check valve” function. That is, when an abnormal pressure is generated on the first flow path 11 or the second flow path 21 side, this pressure is applied to the valve body 52 via the intake port 51, so that the valve body 52 contacts the valve seat 54. This prevents liquid leakage.
