Description

The present invention relates to a fine bubble generator that generates a large amount of fine bubbles for bathing and cleaning, and a fine bubble generating apparatus including the fine bubble generator.

In recent years, it has been elucidated that micro / nano-sized bubbles are effective for water purification, the growth of human bodies and organisms, physiological activity, and the like, and various fine bubble generators and devices have been developed and disclosed. In addition, hydrodynamic swirling fluid negative pressure intake systems, gas-liquid press-in mixing and refinement systems, power mechanical dynamics systems, and the like have been studied and developed as microbubble generators for baths and the like.

However, the above conventional technique has the following problems.
(1) For example, when used for bathing, tap water is once stored in a bathtub, hot water is introduced with a circulation pump, fine bubbles are generated and circulated, and energy such as new electricity is consumed. During the circulation process, there was a problem that the hot water temperature decreased due to the outside air temperature.
(2) Because of the circulation type, dirt such as sebum of the human body is also circulated, adheres to equipment, piping, etc., and after bathing, after draining hot water, the generation of such odors and bacteria due to spoilage is considered and it is not hygienic Had.
(3) Further, when an efficient removal filter or the like is provided, there is a problem that clogging or the like causes a reduction in the generation efficiency of fine bubbles and a failure of the device.
(4) In the case of a swivel type whose structure is not complicated, these concerns are reduced. However, when the gas-liquid mixing chambers are added in multiple stages, the amount of pressurized liquid also increases proportionally, so it overflows immediately in a small volume container such as a bathtub. In addition, since the ejection holes are large, there is a problem that the refinement efficiency by shearing is low.
(5) A method of increasing the amount of fine bubbles by disposing and subdividing a plurality of jets is disclosed. However, in the above method, water is discharged without being refined unless an increase in liquid volume or high pressure is used. Similar to the above, there was a problem of high density efficiency of fine bubbles.
Moreover, if it is not a circulation type, it will be desirable to generate the high density bubble water by increasing the amount of fine bubbles with respect to the liquid amount. Accordingly, an object of the present invention is to provide a fine bubble generator and an apparatus that generate fine bubbles at a high density with respect to the liquid amount without using new energy.

In order to solve the above problems, the present invention is provided with a secondary bubble processing chamber in order to generate fine bubbles more efficiently than the current by an economical and simple structure swirl method, Without increasing the mixing chamber, without increasing the liquid volume, in order to increase only the amount of fine bubbles, to further subdivide the bubbles and increase the bubble density,
(1) In order to suck the gas quickly into the gas-liquid mixer, the area of the pressurized liquid inlet is opened at a ratio of 3: 1 so as to straddle the body cylindrical part and the conical part, and the swirling liquid flow is cylindrical. Introduce into the conical part.
(2) Gas-liquid mixing of a cylindrical piece (hereinafter referred to as a shearing piece) that also serves as a gas-liquid jet hole in the gas-liquid mixing chamber and has triangular protrusions radially arranged on the back (upper entrance of the secondary bubble processing chamber) The gas-liquid is sheared and introduced at the boundary between the vessel and the secondary bubble processing chamber.
(3) Next, a spherical permanent magnet with a small hole passing through the center (ferrite material, anisotropic magnetic field, residual magnetic flux density of about 800 gauss, mirror finish) is disposed.
(4) Further, in order to hold the front two permanent magnets without fixing them, the metal mesh (stainless wire, # 80) hook surface is wound with a stainless steel plate, and the brazed wire mesh hook is supported by the secondary processing chamber wall surface protruding portion. , The boundary with atmospheric pressure water, and then the structure that discharges from the treated water discharge port.
(5) In order to simplify the adjustment of the gas inflow amount (bubble diameter), an adjustment valve (cock) is attached to the body to facilitate visual confirmation and fine adjustment of the bubbles.
(6) The purpose of manufacturing is to reduce the size of the device for use in a bathtub or the like.

According to the present invention, the liquid introduction port is opened across the cylindrical portion and the conical portion of the gas-liquid mixing chamber, and the secondary bubble treatment chamber is provided, so that the conventional swirling mixed bubble water can be increased without increasing the amount of water. The increase and subdivision of only fine bubbles are measured.
(1) Opening the liquid introduction port so as to straddle the cylindrical part and the conical part of the gas-liquid mixing chamber, and the conical part where the flow velocity is increased by setting the ratio of the opening area to 3: 1 By introducing it early, the suction power of gas becomes stronger.
(2) By providing a shearing piece with triangular projections radially attached to the back surface of the gas-liquid mixing chamber ejection hole, the effect of shearing and refining the primary ejection gas-liquid can be enhanced.
(3) By arranging the permanent magnet, an induced microcurrent is generated in the treated water by the MHD action, and the treated water is activated. Furthermore, new cavitation occurs with the suction negative pressure and turbulent flow at the center. Also. Since the magnet rotates and slightly vibrates, it is considered that the generation of cavitation phenomenon (cavitation) of the passing water is enhanced by generating ultrasonic waves.
(4) By providing the brazed wire mesh cage at the end, free holding of the magnet and further shearing and refinement of bubbles can be obtained.
(5) By integrating the gas-liquid mixer and the secondary bubble processing chamber, the vessel can be miniaturized and does not become an obstacle during bathing. You can also hold it in your hand and use it like a shower.
(6) Since the bubble adjusting valve is attached to the body, the bubbles can be easily visually confirmed, confirmed and adjusted.
(7) Unlike the circulation type, fine bubble water (hot water) can be stored and used in the bathtub from the beginning with shower water (hot water), so a fine bubble bath can be made immediately without using new energy.
(8) There is no cooling by circulation, no generation of odors and bacteria, hygienically cleaning and cleaning of the equipment is easy, and there is no electrical accident etc., and it is safe and economical.
(9) The sterilizing power of tap water and fine bubbles is suitable as washing water for tableware, vegetables, laundry, etc.
(10) Further, it is conceivable that, during bathing, the intake air amount adjusting valve is largely opened to generate air bubbles in millimeters and hitting the human body, thereby reducing fatigue and tension.
(11) A plurality of the generators can be installed to purify water such as a pond with a small amount of power.
