The tub is a tub for treating laundry, and for example, the tub may be an inner tub of a drum washing machine, a tub of a pulsator washing machine, or the like. The micro bubble generator 100 is used for generating micro bubble water, and the micro bubble water can be used for participating in a washing process of clothes, a rinsing process of the clothes, and other processes of the clothes treatment equipment requiring the micro bubble water, such as cleaning a sealing ring, cleaning dirt, and the like.

Wherein the detergent box 300 has a washing inlet and a washing outlet, and the laundry treating apparatus further includes a mains water inlet pipe, which may be connected to the washing inlet and/or the water inlet 101 of the micro bubble generator 100, and a water inlet valve connected to the mains water inlet pipe.

The following describes the detailed structure and operation of the microbubble generator 100 in detail.

As shown in fig. 13 and 14, the microbubble generator 100 includes a gas dissolving tank 1 and a cavitation member 2, and the gas dissolving tank 1 defines a gas dissolving chamber 10 therein. The dissolved air vessel 1 has an inlet 11 and an outlet 12 for the flow of water to and from the vessel. The inlet 11 of the dissolved air tank 1 forms the water inlet 101 of the microbubble generator 100, or the inlet 11 of the dissolved air tank 1 communicates with the water inlet 101, and the inlet 11 is connected to a water source (e.g., a mains water inlet pipe of the laundry treating apparatus). The water outlet 102 of the microbubble generator 100 is formed on the cavitation member 2, the cavitation member 2 is arranged outside the dissolved air tank 1 and connected with the outlet 12, or the cavitation member 2 is arranged at the outlet 12, and the cavitation member 2 makes the gas dissolved in the water into microbubbles through cavitation effect.

In some embodiments, the dissolved air tank 1 further has an auxiliary port 18 communicated with the dissolved air chamber 10, a check member 7 is provided at the auxiliary port 18, and the check member 7 is connected with the air delivery member 6 through a connecting pipe 62. In other embodiments, a control valve 4 is provided at the auxiliary port 18 for controlling the opening and closing of the auxiliary port 18.

When the micro-bubble generator 100 is used, the dissolved air tank 1 is filled with water and dissolved air from the inlet 11, water containing high-concentration air solute enters the cavitation part 2, the cavitation part 2 is made into micro-bubbles by utilizing cavitation effect, the water flow discharged from the cavitation part 2 contains a large amount of micro-bubbles, and after the micro-bubble generator 100 is used, the gas transmission part 6 is started or the control valve 4 is opened, so that air is supplemented into the dissolved air cavity 10.

The prepared micro-bubble water can be used for washing and other various purposes. If the water is provided with detergents such as washing powder and laundry detergent, the explosion energy of the microbubbles can accelerate the differentiation of the detergents into smaller parts, thereby promoting the full and rapid dissolution of the detergents. Therefore, the micro-bubble water generated by the micro-bubble generator 100 can be introduced into the detergent box 300 to participate in the dissolution of the detergent, can be introduced into the water tub to participate in the dissolution of the detergent, and can be introduced into other parts of the clothes treatment equipment to participate in the sufficient dissolution of the detergent. If the stains on the clothes are stubborn, the stains are difficult to remove by merely dissolving the detergent or by friction between the clothes. The micro bubble water generated by the micro bubble generator 100 may participate in the washing of the laundry, and the removal capability of the laundry dirt may be enhanced by the explosion energy of the micro bubbles. Similarly, when the micro-bubble water participates in the rinsing process, the explosion energy of the micro-bubbles can enable the detergent stained on the clothes to be dissolved in the water as soon as possible, and the clothes are prevented from being left. In addition, the enhanced capability of the micro-bubble water contributes to saving the water consumption of the clothes treatment equipment.

As shown in fig. 14, in the embodiment of the present invention, the inlet 11 of the dissolved air tank 1 is located above the outlet 12, and the inlet 11 is horizontally offset from the outlet 12. And the micro bubble generator 100 is constructed such that the flow rate of the discharged water is smaller than the flow rate of the entered water when dissolving the gas, that is, the discharged water is less and the entered water is more in the unit time. Rivers are injected into dissolved air tank 1 by entry 11, because the income water velocity of flow is greater than the play water velocity of flow, consequently dissolve the water level in air chamber 10 and rise gradually after air tank 1 pours into a period of water into, can not sink export 12 very fast after dissolving the water level in air chamber 10 and rise, make export 12 department form the water seal, dissolve air chamber 10 upper portion cavity and step up gradually and form the high-pressure chamber, make the air of non-dissolved state be difficult to discharge, the solubility of air under the high-pressure state is greater than the solubility under the low pressure state, consequently, the solubility of air in aquatic in dissolved air chamber 10 can greatly increased, thereby accomplish dissolved air. A large amount of air is dissolved in the water flowing to the cavitation member 2, so that a large amount of microbubbles can be generated by the cavitation member 2.

It is emphasized here that although water is still discharged from the outlet 12 to the cavitation member 2 after the water seal is formed at the outlet 12, water is continuously supplied to the inlet 11, so that the water level in the air-dissolving chamber 10 is continuously increased, which leads to the air space above the water surface being gradually reduced, and when the air pressure in the air-dissolving tank 1 is gradually increased to be close to the water pressure of the supplied water, the flow rate of the supplied water is equal to the flow rate of the supplied water.

In addition, because the inlet 11 is positioned above the outlet 12, when the inlet 11 enters water, the water is flushed to the water surface from the upper part, so that the water surface is agitated, and meanwhile, part of high-pressure air is brought in, and the dynamic contact area between the air and the water can be increased. And because the inlet 11 and the outlet 12 are staggered in the horizontal direction, the flow path of the water flow in the dissolved air cavity 10 is longer, so that bubbles generated by the impact of the water flow are reduced to be entrained by the water flow and flow out of the outlet 12, and the dissolving time and the contact area of the excited bubbles in the water body are increased.

Adopt rivers to arouse the scheme that the board set up between entry 11 and export 12 among the prior art, the embodiment of the utility model provides a just through stagger entry 11, export 12 on the horizontal direction, just can reach same effect, utilize gas dissolving chamber 10 diapire or the surface of water to act as rivers and arouse the board. The utility model discloses in dissolving gas chamber 10, can set up rivers and arouse the board in order further to strengthen water excitation, also can save rivers and arouse the manufacturability of board in order to improve dissolved gas pitcher 1.

In some alternative embodiments, as shown in fig. 14, the baffle 3 is at least partially located between the inlet 11 and the outlet 12 in the horizontal direction, and can intercept the water flowing from the inlet 11 in the process of flowing towards the outlet 12.

Further, as shown in fig. 15, a gap 31 is provided on the baffle 3, or a through hole is provided on the baffle 3, or a gap 31 and a through hole are provided on the baffle 3, so that water dissolving air flows through, but bubbles excited by water bloom in the air dissolving cavity 10 are blocked, and the large bubbles are prevented from flowing to the cavitation part 2, thereby further reducing the waste of air in the air dissolving cavity 1, avoiding the air pressure in the air dissolving cavity 10 from rapidly dropping to affect the dissolved air, and further, after the large bubbles flow into the cavitation part 2, the cavitation effect can be affected. In addition, the baffle 3 is arranged, more spray can be formed when incident water flow is shoved on the baffle 3, and the baffle 3 can also be used as a reinforcing structure to enhance the pressure bearing capacity of the dissolved air tank 1.

The fact that the baffle 3 is located at least partly horizontally between the inlet 11 and the outlet 12 means that the baffle 3 may be located entirely between the inlet 11 and the outlet 12 as shown in fig. 14, and that the baffle 3 may also be located only partly between the inlet 11 and the outlet 12. For example, the baffle 3 may be formed as an arcuate plate or a spherical plate, with the baffle 3 shrouding the outlet 12, with the baffle 3 only partially between the inlet 11 and the outlet 12.

In some embodiments, the baffle 3 is located entirely between the inlet 11 and the outlet 12 in the horizontal direction, which may reduce manufacturing difficulties.

As shown in fig. 14 and 15, in the present embodiment, the baffle 3 is formed as a flat plate and is vertically attached to the bottom wall of the dissolved air tank 1. Therefore, the air bubble generated by water flow excitation can be prevented from flowing out of the dissolved air tank 1, and the production and the manufacture can be facilitated. The flat baffle 3, whether integrally formed with the gas tank 1 or secured to the gas tank 1 by means of a plug or weld, is much easier than a curved plate. Of course, this does not exclude that in other embodiments of the invention the baffle 3 is formed as an inclined plate, a double hollow plate, or as the above mentioned arc plate, spherical plate, etc.

Specifically, as shown in fig. 15, the slits 31 in the baffle 3 are formed in vertical strips in the up-down direction, which also greatly improves the manufacturability of the microbubble generator 100. In fig. 15, only one slit 31 is provided, and in other embodiments, the baffle 3 may be formed as a grating plate having a plurality of slits 31.

In other embodiments, the baffle 3 is a perforated plate 29 having a plurality of through holes, or both the slits 31 and the through holes are provided in the baffle 3.

In some embodiments, when the baffle 3 is provided with the slit 31, the width of the slit 31 is 50mm or less. It will be appreciated that the width of the gap 31 in the baffle 3 needs to be small to avoid bubbles formed by water flow excitation through the gap 31. Preferably, the width dimension of the slit 31 is in the range of 1-10 mm. Of course, the size of the gap 31 may be selected according to actual circumstances, and is not limited to the above range.

Optionally, the horizontal distance between the baffle 3 and the outlet 12 is greater than the horizontal distance between the baffle 3 and the inlet 11, that is, the baffle 3 is closer to the inlet 11 in the horizontal direction, so as to ensure the blocking effect of the baffle 3 on the water flow excitation bubble, and thus ensure the gas dissolving effect of the gas dissolving tank 1. Preferably, the horizontal distance between the baffle 3 and the inlet 11 is less than 50 mm.

When the air in the air dissolving tank 1 is gradually dissolved, the air in the air dissolving tank 1 is gradually reduced. After the microbubble generator 100 is used each time, the microbubble generator 100 stops water inflow, and at this time, the gas transmission part 6 can be started or the control valve 4 can be opened, so that the normal pressure in the gas dissolving cavity 10 is quickly recovered. Moreover, when water stops entering the air dissolving cavity 10, the air content is low, the air pressure in the air dissolving cavity 10 is lower than the external atmospheric pressure, and micro bubble water in the cavitation member 2 and even in a pipeline connected with the cavitation member 2 can be sucked back into the air dissolving cavity 10. After that, the normal pressure of the gas-dissolving chamber 10 is restored, and the residual water inside is discharged from the opened cavitation member 2. After this process, even if a little water remains in the dissolved air chamber 10, the amount of the remaining water is not too large, and sufficient air is present in the dissolved air tank 1, thereby ensuring that the microbubble generator 100 can dissolve sufficient air for the next use.

In the above embodiment, it is proposed that the dissolved air tank 1 dissolves air in water as a solute, that is, the air is dispersed in water molecules in an ionic form. The dissolved state disperses air ions, and the air ions in water molecules are more uniform. The bubbles separated by cavitation effect are mostly only of nanometer and micrometer size at the initial stage of formation, which is the microbubbles that our microbubble generator 100 is expected to obtain. Even if the water with the microbubbles flows to a final use place, the microbubbles are mutually dissolved, most of the obtained microbubbles can still be kept at a millimeter level or even smaller, the effect is optimal, and the explosion energy can be effectively transmitted between fibers with millimeter level and micron level and on detergent particles.

And if the bubbles are injected into the water by force, the bursting time of the bubbles is too fast, and the bubbles cannot participate in the whole washing process. The air dissolved in water is not completely separated out in the cavitation part 2, and the air dissolved in water can slowly supplement micro bubbles in the whole washing process, so that micro bubble water is continuously generated, micro bubbles participate in the whole washing process, and the washing capacity and the rinsing capacity of the clothes treatment equipment are improved.

Air is a poorly soluble gas with respect to water. The percentage of the amount of air dissolved in water to the amount of air introduced is called the dissolved air efficiency, which is related to the temperature, the dissolved air pressure and the dynamic contact area of the gas phase and the liquid phase. The method of changing the water temperature or the air temperature is difficult to implement. A common method for improving the air dissolving efficiency is to pressurize the air dissolving chamber 10 by a booster pump, but various valves are required, so that the cost for configuring the booster pump is too high.

In the prior art, a double inlet is arranged in the air dissolving device, one inlet is used for water inlet, and the other inlet is used for air inlet at the same time of water inlet. In order to inject air into flowing water, a booster pump is required to push air into the water. Because the air inlet is located the below of cavitation spare 2 in this scheme, the bubble of entering can flow towards cavitation spare 2 fast and extrude, does not provide the space in the dissolved air jar 1 and lets the bubble dissolve slowly, and the dissolved air effect is not ideal. The way of injecting air into water by means of pressurization is equivalent to directly pressing large air bubbles into water. The large bubbles have short retention time in water and insufficient dissolution time. Even if large bubbles are squeezed into more small bubbles by the cavitation member 2 while passing through the cavitation member 2, the small bubbles are rapidly burst and released with a size of millimeter or more.

The microbubble generator 100 of the present application utilizes the difference in water flow speed of the gas dissolving cavity 10 and the difference in height between the inlet 11 and the outlet 12 to form a water seal at the outlet 12, so that the gas dissolving cavity 10 gradually increases in pressure to form a high pressure cavity, thereby improving the gas dissolving capacity. The gas transmission part 6 or the control valve 4 is arranged to enable the dissolved air cavity 10 to discharge residual water and supplement air after the micro-bubble generator 100 is used each time.

The cavitation piece 2 of microbubble generator 100 of this application links to each other with detergent box 300, leads little bubble water to detergent box 300 and flows to the ladle again, can reduce the connecting pipe quantity on the ladle, is convenient for on the one hand sealed, and on the other hand the high integrated level structure can reduce the volume, need not to install a plurality of valves, has realized the emergence of microbubble with comparatively simple structure, is favorable to improving compactness, integrated level and stability. Above-mentioned microbubble generator 100 need not to install a plurality of valves, and is with low costs, microbubble manufacturing effect is good. The washing water contains a large amount of micro bubbles, so that the consumption of the washing agent is reduced, the water and electricity resources are saved, and the residual washing agent on clothes is reduced.

In the embodiment of the present invention, the dissolved air tank 1 may be formed in any shape, and the shape of the dissolved air tank 1 is not specifically limited herein. However, the dissolved air tank 1 needs to ensure that the dissolved air tank 1 needs to have good sealing performance at other positions except the outlet 12 during the dissolved air operation.

In particular, the cross-sectional area of the portion of the chamber 10 perpendicular to the inlet 11 is small, and it will be appreciated that as water enters the chamber 10, the incident water will strike the inner wall of the chamber 10 and the level of the liquid in the chamber 10. More water bloom can be generated by the phenomenon, and the water bloom is favorable for bringing the water body into the high-pressure air above, so that the dissolving speed of the air in the water body is increased. The cross section of the part, perpendicular to the inlet 11, of the air dissolving cavity 10 is small, so that water splash generated in the process that water surface is hit by incident water flow of the inlet 11 is facilitated, and a relatively strong physical effect is generated between the water splash and the inner wall of the air dissolving cavity 10, and therefore the water body can dissolve air quickly.

As shown in fig. 14-15, the inlet 11 is located at or near the topmost portion of the dissolved air tank 1; the outlet 12 is located at or near the lowermost portion of the dissolved air tank 1.

In some alternative embodiments, as shown in fig. 14-15, the incident direction of the inlet 11 is vertically downward, and the inflow water flow is injected into the air dissolving chamber 10 in the vertical direction, which both increases the generation of water splash, thereby increasing the air dissolving speed, and facilitates the manufacturability of mass production of the air dissolving tank 1. Of course, in other embodiments of the present invention, the incident direction of the inlet 11 may also be inclined, that is, the incident direction of the water flow may form a certain angle with the vertical direction, so that the impact area of the incident water flow is very large.

In some embodiments, in the horizontal direction, as shown in fig. 14, the inlet 11 and the outlet 12 are located at both ends of the dissolved air tank 1, thereby further lengthening the flow path of the water flow inside the dissolved air tank 1 and further reducing the water bubbles hit by the water flow to flow out through the outlet 12.

The cross section of the air-dissolving chamber 10 in the horizontal direction is square, and the inlet 11 and the outlet 12 are arranged at the positions farthest away from the straight line corresponding to the two ends of the square. For example, the air dissolution chamber 10 has a rectangular cross section in the horizontal direction, and the inlet 11 and the outlet 12 are located at both ends of the long side of the rectangle. Such a gas dissolving tank 1 is easy to manufacture and easy to arrange during assembly. Of course, in other embodiments of the present invention, the cross-sectional shape of the air dissolving chamber 10 may be formed in any shape and is not limited to a rectangle, a diamond, or other irregular square.

Advantageously, as shown in fig. 14, the inlet 11 is located at the uppermost part of the air-dissolving chamber 10, which ensures that the incident water flow can excite more water flowers and improve the air-dissolving effect. Alternatively, the outlet 12 is located at the lowest part of the air-dissolving chamber 10, which enables the outlet 12 to be water-sealed as quickly as possible.

In some embodiments, the distance between the inlet 11 and at least one side wall of the gas dissolving chamber 10 is less than 50 mm. Namely, when the inlet 11 is in a working state, the distance between the projection of the inlet 11 to the water surface in the vertical direction and the inner wall surface of at least one air dissolving cavity 10 is less than 50 mm. The water flow at the inlet 11 is easier to impact the side wall of the dissolved air tank 1 to generate water splash, thereby improving the air dissolving effect of the dissolved air tank 1. Optionally, the distance between the inlet 11 and at least one side wall of the gas dissolving chamber 10 is between 1-20 mm. Of course, in other embodiments of the present invention, the inner wall of the air dissolving cavity 10 may be provided with a protruding inner rib structure, so as to make it easier to stimulate the splash.

In the embodiment of the present invention, the dissolved air tank 1 is formed by two half dissolved air shells 13 that are fastened to each other, the inlet 11 is formed on one of the half dissolved air shells 13, and the outlet 12 is formed on the other half dissolved air shell 13. The inlet 11 and the outlet 12 are respectively arranged on the two dissolved air half shells 13, so that the forming is easy, and the strength of each dissolved air half shell 13 is not too low. The gas dissolving tank 1 has the advantages of strong manufacturability, convenience for batch production and low processing cost.

In some embodiments, the two dissolved air half-shells 13 are joined by welding or gluing, so as to ensure tightness. In other embodiments, the gas dissolving tank 1 is a plastic part, for example, each gas dissolving half shell 13 is an integral injection molded part.

Wherein, dissolve the upper portion of gas pitcher 1 and be equipped with the oral siphon 14 that communicates the gas pitcher 10 top, dissolve the lower part of gas pitcher 1 and be equipped with the outlet pipe 15 that communicates the gas pitcher 10 bottom, oral siphon 14 and the setting of outlet pipe 15 level can be convenient for like this assemble. For example, when the microbubble generator 100 is used integrally with the detergent box 300, the dissolved air tank 1 is installed behind the detergent box 300, and the water inlet pipe 14 and the water outlet pipe 15 are horizontally disposed to make assembly easier.

As shown in fig. 14 to 15, in the present embodiment, two gas-dissolving half shells 13 are disposed up and down, the water inlet pipe 14 is integrally formed on the upper gas-dissolving half shell 13, and the water outlet pipe 15 is integrally formed on the lower gas-dissolving half shell 13, so that the processing convenience and the sealing property can be ensured.

Specifically, the two dissolved air half shells 13 are in contact fit at the splicing position through the step surface 16, so that the contact area of the contact position of the two dissolved air half shells 13 is increased, and the contact strength is also improved. In addition, the step surface 16 is in contact fit, so that at least part of the contact surface of the two dissolved air half shells 13 is perpendicular or nearly perpendicular to the pressure of the inner wall of the dissolved air cavity 10. Therefore, the two gas dissolving half shells 13 are pressed more and more tightly at the splicing position due to the internal high pressure, and the splicing position is prevented from cracking and leaking gas due to the internal high pressure.

Furthermore, the outer surface of the dissolved air tank 1 is provided with reinforcing ribs 17 which are arranged in a transversely and longitudinally staggered manner, so that the strength of the dissolved air tank 1 can be increased, and deformation and air leakage caused by internal high pressure are avoided.

In the embodiment of the present invention, the cavitation member 2 may adopt a structure of a cavitation device known in the prior art, for example, an ultrasonic generator, for example, at least one venturi channel 25 is formed in the cavitation member 2.

In some alternative embodiments, as shown in fig. 17, the cavitation member 2 is an orifice plate 29 provided with a plurality of minute holes. This makes it possible to easily separate out the air dissolved in the water flow passing through the cavitation member 2 and to form bubbles. Specifically, the radius of the micropores on the orifice plate 29 is 0.01mm to 10 mm. Experiments prove that the orifice plate 29 with the parameters has better cavitation effect and can generate more bubbles. Of course, the specific parameters of the orifice plate 29 can be adjusted by the operator according to the actual working conditions, and are not limited to the above ranges.

In other alternative embodiments, as shown in fig. 16, the cavitation member 2 includes venturi tubes 28, one venturi tube 28 forming one venturi channel 25. This makes it possible to relatively easily separate out the air dissolved in the water flow passing through the cavitation member 2 and to form bubbles. The venturi tube 28 is adopted as the cavitation member 2, and unnecessary water pumps, heating devices or control valves and the like do not need to be designed, so that the structure of the cavitation member 2 is greatly simplified, the production cost is reduced, and the venturi tube 28 has no additional requirement on a water inlet mode, so that the cavitation member 2 can easily generate a large amount of bubbles.

In some embodiments, as shown in fig. 18-20, the cavitation member 2 is formed as a deformed structure having a plurality of venturi channels 25. As shown in fig. 18, the cavitation member 2 is a substantially cylindrical body, and a plurality of venturi passages 25 are provided in the cavitation member 2. Such structure on the one hand lengthens the path length of the venturi channel 25, is favorable for the sufficiency of the time of exerting the venturi effect, on the other hand is convenient for processing and manufacturing, is convenient for assembling, and is very convenient when being connected with the pipe orifice.

Specifically, as shown in fig. 20, the venturi channel 25 in the cavitation member 2 includes, in order in the water flow direction: a tapered section 251, a throat 252, and a diverging section 253, the tapered section 251 decreasing in diameter in a direction toward the throat 252, the diverging section 253 increasing in diameter in a direction away from the throat 252, and the throat 252 having a minimum flow area within the venturi channel 25.

Specifically, the cavitation member 2 is formed in a cylindrical shape, the opposed ends of the cavitation member 2 are formed with a diversion groove 261 and a confluence groove 262, respectively, and the venturi passage 25 is formed between the bottom wall of the diversion groove 261 and the bottom wall of the confluence groove 262.

The cavitation member 2 is generally connected to the laundry treating apparatus by a pipe, so that the inside diameter of the outlet end of the cavitation member 2 may be selected to be 5-15 mm. Further alternatively, the inner diameter of the outlet end of the cavitation member 2 is controlled to be between 7 and 10 mm. In the example of FIG. 20, the diameter of the bus bar slots 262 may alternatively be between 5-15mm, and further alternatively between 7-10 mm.

Optionally, the number of venturi channels 25 is 1-30, further optionally, the number of venturi channels 25 is 4-6. The cavitation member 2 is a key component and needs to bear the treatment of the water flow of the clothes treatment equipment, and the water entering the clothes treatment equipment generally adopts domestic tap water. The flow rate of the domestic tap water is generally 5-12L/min, and the water pressure is generally 0.02-1 Mpa. More generally, the flow rate is generally 8-10L/min, and the water pressure is generally 0.15-0.3MPa, so that the number of the Venturi passages 25 in the cavitation member 2 can be selected from 4-6.

The relevant principle of cavitation is:

the average speed, average pressure and cross-sectional area at the inlet end of the tapered section 251 are respectively V1, P1 and S1, the average speed, average pressure and cross-sectional area at the throat 252 are respectively V2, P2 and S2, the density of water is rho, and in an operating state, the clothes treating device takes tap water as an operating medium, and the relation is satisfied: S1V 1 ═ S2V 2.

The relationship can be obtained using bernoulli's law and the continuity equation: v12/2+ P1/, V/2+ P2/, respectively.

In the process, the flow velocity at the throat 252 is increased and the pressure at the throat 252 is decreased in the venturi passage 25 by controlling the changes of S1 and S2, so that the air dissolved in the water is released in the form of micro bubbles.

The diverging section 253 is a diverging section, and the ideal diverging section is to gradually decelerate the fluid, so the diverging section 253 needs a certain length. Optionally, the length of the diverging section 253 is greater than the length of the tapering section 251, further optionally, the length ratio of the tapering section 251 to the diverging section 253 is 1:2-1:4, and further optionally, the length ratio of the tapering section 251 to the diverging section 253 is 1:3-1: 4.

Since the venturi passage 25 needs to be distributed in the cavitation member 2 having a relatively limited sectional area, the diameter of the venturi passage 25 is limited everywhere. Optionally, the diameter of the throat is 0.7-2.0mm, further optionally, the diameter of the throat is 0.9-1.1 mm. In addition, the diameters of the end parts of the tapered section 251 and the diverging section 253 are larger than the diameter of the throat 252 by at least 0.1 mm. Optionally, the diameter of the end of the tapered section 251 remote from the throat 252 ranges from 1 to 4mm, and the diameter of the end of the diverging section 253 remote from the throat 252 ranges from 1 to 4 mm. Further optionally, the ratio of the diameter of the throat 252 to the end diameter of the tapered section 251 is about 1: 1.3-2. The ratio of the diameter of throat 252 to the end diameter of diverging section 253 is about 1: 1.3-2.

Further, as shown in fig. 18 to 20, for the convenience of installation, a threaded section 231 is formed at one end of the cavitation member 2, and the threaded section 231 may be an internal thread or an external thread. In the example of fig. 17 and 19, the threaded section 231 of the cavitation member 2 at the end connected to the gas dissolving tank 1 is an external thread, and is screwed on the gas dissolving tank 1, so that the connection is very convenient.

In other embodiments, as shown in fig. 21, the cavitation member 2 includes: a cavitation shell 23 and a cavitation sphere 24. The cavitation shell 23 is internally provided with a water passing cavity 20, the cavitation shell 23 is provided with a cavitation inlet 21 and a cavitation outlet 22 for water flow to and from, and the cavitation inlet 21 is connected with the outlet 12 of the dissolved air tank 1. The cavitation ball 24 is movably arranged in the water passing cavity 20, the water flowing in from the cavitation inlet 21 can push the cavitation ball 24 to be blocked at the cavitation outlet 22, and when the cavitation ball 24 is blocked at the cavitation outlet 22, a Venturi channel 25 is formed between the cavitation ball 24 and the inner wall of the water passing cavity 20.

When the cavitation ball 24 is blocked at the cavitation outlet 22, a venturi channel 25 communicated with the cavitation outlet 22 is arranged between the cavitation ball 24 and the inner wall of the water passing cavity 20. It is shown here that the cavitation bulb 24 does not completely close off the cavitation outlet 22, but leaves a venturi channel 25 so that the water stream with dissolved air gradually flows out of the cavitation outlet 22.

By arranging the movable cavitation ball 24 in the water passing cavity 20 in front of the cavitation outlet 22, when water flow dissolved with air is continuously introduced into the cavitation inlet 21, the continuously introduced water flow flows along the inner wall of the water passing cavity 20, and after encountering the cavitation ball 24, the cavitation ball 24 is pushed to move towards the cavitation outlet 22, so that the cavitation ball 24 moves to the front of the cavitation outlet 22 and gradually stops against the cavitation outlet 22 to form a venturi channel 25.

When the water flow with dissolved air solute passes through the venturi channel 25, the flow area will be reduced first and then increased. When the flow area is reduced and the flow velocity of the water flow with the gas solute is increased, the pressure is reduced. The flow area is increased, and the pressure is increased when the flow velocity of the water flow of the gas solute is decreased. A venturi effect is generated in the venturi channel 25, and air is separated from the solute state to form micro-bubbles. And the water flow keeps the cavitation sphere 24 stopped against the cavitation outlet 22 and also causes the water flow with dissolved air solutes to exit the venturi channel 25 more quickly.

In the process, the water flow which is continuously introduced is larger than the water flow which flows out, the water passing cavity 20 is used as an air-tight cavity, and when the cavitation outlet 22 of the water passing cavity is stopped against the cavitation ball 24, the pressure in the water passing cavity is increased, so that the cavitation effect is enhanced.

The cavitation piece 2 has the advantages of low cost and low processing difficulty, and is not possessed by other cavitation structures. The cavitation ball 24 is a movable sphere, when the micro-bubble generator 100 stops working, the water flow is reduced, and the cavitation ball 24 will leave the cavitation outlet 22 without the pressure of the water flow, so that the residual water in the micro-bubble generator 100 can be removed as soon as possible. On the one hand, the air is convenient to store in the air dissolving tank 1 in advance, and on the other hand, the accumulated water deposition is avoided, so that the breeding of excessive bacteria is avoided. In addition, the cavitation member 2 is also convenient to clean.
