[0059] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0061] like Figures 1 to 4 As shown, Figure 1 A schematic diagram of a bubble generator provided by the present invention is shown. Figure 2 A schematic diagram showing that the diversion groove 221 provided by the present invention is spiral-shaped. Figure 3 1 shows a top view of the conical housing 21 and the diverter trough 221 when the diverter trough 221 provided by the present invention is a straight-through structure. Figure 4 1 shows a top view of the conical shell 21 and the diverter groove 221 when the diverter groove 221 provided by the present invention is a spiral structure.

[0062] The bubble generator according to the embodiment of the present invention comprises:

[0063] Shell assembly 1, including a shell assembly inlet and a shell assembly outlet;

[0064] The bubble generator body 2 is installed inside the shell assembly 1 and is connected to the shell assembly inlet and the shell assembly outlet. It includes a conical shell 21 and a diverter core 22, wherein the diverter core 22 is inserted into the interior of the conical shell 21 and forms a microbubble channel with the conical shell 21. The diverter core 22 is used to convert the gas-liquid mixture into microbubble water, and the microbubble channel is used to transport the microbubble water to the shell assembly outlet.

[0065] Among them, the shell assembly 1 is a cylindrical shell, and the output end of the conical shell 21 is gap-fitted with the inner wall of the shell assembly 1, so that the conical shell 21 is fixed to the shell assembly 1, and the diverter core 22 is installed in the conical shell 21. In this embodiment, the shell assembly 1 and the conical shell 21 can be fixed by detachable means such as threaded connection, bonding, and clamping. For example, a shell assembly protrusion is set inside the shell assembly 1, and a conical shell recess is set at the corresponding position of the conical shell 21 to achieve detachable connection between the shell assembly 1 and the conical shell 21. As long as the conical shell 21 can be fixed to the shell assembly 1, the structure is simple. In addition, the diverter core 22 and the conical shell 21 can be connected by welding, bolts, or in an integrated molding manner. The present invention does not limit this. A microbubble channel is formed between the conical shell 21 and the diverter core 22, which can release the gas in the gas-liquid mixture at a relatively low pressure and form microbubbles, that is, the gas-liquid mixture can be converted into high-quality microbubble water. The upper portion of the housing assembly 1 is provided with internal threads for easy installation on the water outlet of a faucet, shower head, etc. The outer periphery of the housing assembly 1 is provided with flat cutouts for easy installation and removal with a wrench or a rolled edge pattern for easy hand rotation. This invention solves the problems of existing bubble generators, such as complex structure, inconvenient assembly and disassembly, and the need for high pressure to produce high-quality microbubble water. When the gas-liquid mixture in this embodiment is tap water or purified water containing air.

[0066] In a preferred embodiment of the present invention, the diverter core 22 is a cone, which is gap-fitted with the inner wall of the conical shell 21, and is provided with a diverter groove 221 and a diffusion hole 222, wherein the diffusion hole 222 is a conical through hole, the central axis of the diffusion hole 222 is collinear with the central axis of the diverter core 22, the diverter groove 221 is distributed on the outer peripheral surface of the diverter core 22, the diverter groove 221 and the inner wall of the conical shell 21 form a microbubble channel, and the diffusion hole 222 forms a microbubble channel to transport microbubble water to the outlet of the shell assembly.

[0067] like Figure 2-4 As shown, the conical shell 21 is preferably made of plastic injection molding, and the conical shell 21 includes a large end of the conical shell and a small end of the conical shell, wherein the diameter of the small end of the conical shell is between Φ3 and Φ5 mm, the diameter of the large end of the conical shell is between Φ12 and Φ20 mm, and the height of the conical shell 21 is between 15 and 25 mm. The diverter core 22 is a cone, and a plurality of diverter core blocks are preferably provided at the bottom of the diverter core 22. The plurality of diverter core blocks are distributed along the circumference so that the diverter core 22 can be inserted into the conical shell 21. A diverter groove 221 is provided on the outer periphery of the diverter core 22, and the diverter groove 221 and the inner wall of the conical shell 21 form a microbubble channel. At the same time, a diffusion hole 222 is provided downwardly from the top of the diverter core 22, and the diffusion hole 222 forms a microbubble channel. The microbubble channel is used to convert the gas-liquid mixture transported from the shell component inlet into microbubble water, and transport the microbubble water to the shell component outlet, and then flow out of the outer shell 11.

[0068] In a preferred embodiment of the present invention, there are at least two diverter grooves 221, which are arranged at equal intervals along the outer circumference of the diverter core 22. The diverter grooves 221 become larger and deeper along the flow direction of the gas-liquid mixture to fully release the pressure of the gas-liquid mixture to obtain micro-bubble water.

[0069] like Figure 2-4 As shown, the diverter 221 can be a straight-through structure or a spiral structure, which makes the water flow smoother. After the diverter 221 releases the pressure of the gas-liquid mixture, microbubbles with uniform particles, small size and large number can be obtained, thereby obtaining high-quality microbubble water, effectively improving the user's water experience. The spiral structure can make the generated microbubbles more uniform. The cross-section of the microbubble channel formed by the diverter 221 and the conical shell 21 is an olive-shaped structure, and the cross-section of the microbubble channel continues to increase as the gas-liquid mixture flows, which can fully release the pressure of the gas-liquid mixture to obtain microbubble water. The diverter 221 adopts a diverter linear diffusion structure, that is, the diverter 221 becomes larger and deeper along the flow direction of the gas-liquid mixture, so that the gas in the gas-liquid mixture can be released under a smaller pressure and form microbubbles with uniform particles, small size and large number, thereby obtaining high-quality microbubble water.

[0070] In a preferred embodiment of the present invention, a limiting sealing assembly 10 is also included, which includes a limiting circular plate and a limiting washer located on the limiting circular plate, wherein a limiting through hole is set in the middle of the limiting circular plate, and the limiting circular plate is sleeved on the top of the conical shell 21. The outer periphery of the limiting circular plate is matched with the internal clearance of the outer shell assembly 1, and an internal threaded portion is provided on the upper part of the outer shell assembly 1. The outer shell assembly 1 below the internal threaded portion is provided with an outer shell groove for installing the limiting washer to limit the position of the limiting circular plate.

[0071] Figure 1 As shown, the bubble generator body 2 is installed on the shell assembly 1, and then the limiting circular plate is clamped on the top of the conical shell 21, and the limiting gasket is clamped into the outer shell groove to limit the position of the limiting circular plate. Since the conical shell 21 is a conical structure, the limiting through hole can be clamped on the conical shell 21. In addition, the limiting gasket can not only limit the position of the limiting circular plate, but also prevent moisture from entering the gap between the outer shell assembly 1 and the conical shell 21, thereby playing a sealing role. In order to increase the connection strength between the limiting circular plate and the conical shell 21, in this example, the limiting circular plate and the conical shell 21 can be connected by threading, welding, etc., and the present invention does not limit this.

[0072] like Figures 5 to 20 As shown, Figure 5 A schematic diagram of a microbubble generating device provided by the present invention is shown. Figure 6A cross-sectional view of a microbubble generating device provided by the present invention is shown.

Figure 17 A cross-sectional view of the microbubble generating device provided by the present invention when the large water column channel is closed is shown. Figure 18 A cross-sectional view of the microbubble generating device provided by the present invention when the large water column channel is opened is shown. Figure 19 The diagram shows the status of the large water column mechanism rotating part 30 and the regulating device rotating part 40 when the large water column channel provided by the present invention is closed. Figure 20 The diagram shows the status of the large water column mechanism rotating part 30 and the regulating device rotating part 40 when the large water column channel provided by the present invention is opened.

[0073] The microbubble generating device according to the embodiment of the present invention comprises:

[0074] A bubble generator such as any of the above;

[0075] A large water column mechanism 3 is mounted on the bubble generator and communicates with the housing assembly inlet and the housing assembly outlet. It includes a large water column mechanism body and a large water column mechanism rotating portion 30 provided on the large water column mechanism body. One side of the large water column mechanism body is detachably mounted on the housing assembly 1, and the other side is fixedly connected to the bubble generator body 2. The large water column mechanism body forms a large water column channel with the housing assembly 1 and the bubble generator body 2. The large water column channel is used to transport the gas-liquid mixture to the housing assembly outlet in the form of a large water column.

[0076] The regulating device 4 is partially inserted into the large water column channel, and includes a regulating device body and a regulating device rotating part 40 arranged on the regulating device body, wherein the regulating device rotating part 40 and the large water column mechanism rotating part 30 rotate relative to each other to push the regulating device body to open or close the large water column channel.

[0077] The bubble generator in this embodiment includes any of the aforementioned bubble generators. Since the aforementioned bubble generators have the aforementioned technical effects, the micro-bubble generating device having the aforementioned bubble generators should also have the same technical effects. It should be noted that in this example, the position-limiting seal assembly 10 in the bubble generator cannot affect the use of the large water column channel. It can be set between the large water column mechanism 3 and the housing assembly 1, or the position-limiting seal assembly 10 can be discarded.

[0078] In this embodiment, the diverter core 22 is gap-fitted with the inner wall of the conical shell 21 so that the diverter core 22 can be inserted into the conical shell 21, and the large water column mechanism 3 is fixed to the conical shell 21. When in use, the bubble generator body 2 and the large water column mechanism 3 are both installed on the shell assembly 1 and are connected to the shell assembly inlet and the shell assembly outlet. After the gas-liquid mixture enters the shell assembly inlet, it can enter the microbubble channel and the large water column channel. The microbubble channel is used to convert the gas-liquid mixture into microbubble water and transport it to the shell assembly outlet. The large water column channel is used to transport the gas-liquid mixture to the shell assembly outlet in the form of a large water column. The large water column channel can be opened or closed by rotating the rotating part 40 of the regulating device and the rotating part 30 of the large water column mechanism. When the large water column channel is opened, it is transported to the shell assembly outlet in the form of a large water column and microbubble water to meet the customer's large flow usage needs; when the large water column channel is closed, the gas-liquid mixture is transported to the shell assembly outlet in the form of microbubble water to meet the smaller water consumption needs. The bubble generator body 2, large water column mechanism 3, and regulating device 4 are all detachably connected to the housing assembly 1. The large water column mechanism 3 and regulating device 4 are rotatably connected. The present invention has a simple structure and design, is easy to process, and is convenient to assemble and disassemble. Through the relative rotation between the large water column mechanism 3 and regulating device 4, it can meet the user's different water volume requirements. The gas-liquid mixture in this embodiment can be tap water containing air or purified water.

[0079] In a preferred embodiment of the present invention, the main body of the large water column mechanism is sleeved on the outer periphery of the conical shell 21, and the main body of the large water column mechanism includes a first cylinder 31 and a second cylinder 32, wherein the second cylinder 32 is located below the first cylinder 31, and a large water column channel is formed between the first cylinder 31 and the conical shell 21, and between the second cylinder 32 and the conical shell 21.

[0080] As shown in 10-12, the first cylinder 31 and the second cylinder 32 are respectively fixed to the outer circumference of the conical shell 21, and the second cylinder 32 is located below the first cylinder 31. A large water column channel is formed between the first cylinder 31 and the conical shell 21, and between the second cylinder 32 and the conical shell 21. In addition, connecting plates are provided between the first cylinder 31 and the conical shell 21, and between the second cylinder 32 and the conical shell 21, for fixing the first cylinder 31 and the conical shell 21, and the second cylinder 32 and the conical shell 21, respectively. Preferably, there are multiple connecting plates, and the multiple connecting plates are circumferentially distributed in the large water column channel to enhance the connection strength between the first cylinder 31 and the conical shell 21, and between the second cylinder 32 and the conical shell 21, and to divert the gas-liquid mixture to improve the water use experience.

[0081] In a preferred embodiment of the present invention, the shell assembly 1 includes an outer shell 11 and an inner shell 12 threadedly connected to the inside of the outer shell 11. The large water column mechanism body also includes an annular plate 33, which is fixed to the outer periphery of the first cylinder 31. The inner shell 12 is provided with an inner shell groove 121, and the annular plate 33 is provided with an annular plate clamping block 331 corresponding to the inner shell groove 121. The annular plate clamping block 331 is inserted into the inner shell groove 121 to clamp the large water column mechanism 3 to the inner shell 12.

[0082] like Figure 5-6 As shown in 12-15, the upper portion of the outer shell 11 is provided with an outer shell internal thread 112, and the outer portion of the inner shell 12 is provided with an outer shell external thread, so that the inner shell 12 is threadedly connected to the inside of the outer shell 11; the outer shell step 111 on the inner side of the bottom of the outer shell 11 is inserted into the inner shell groove 121 through the annular plate block 331, which can enable the large water column mechanism 3 to be clamped to the inner shell 12, so that the large water column mechanism 3 and the inner shell 12 cannot rotate relative to each other. Since the inner shell 12 is threadedly connected to the outer shell 11, one side of the large water column mechanism body is clamped to the inner shell 12, and the other side of the large water column mechanism body is fixed to the bubble generator body 2. When the outer shell 11 is rotated, the outer shell 11 can drive the large water column mechanism 3 to rotate through the inner shell 12, and the large water column mechanism 3 drives the bubble generator body 2 to rotate. The large water column mechanism 3 and the inner shell 12 are clamped, which facilitates the assembly and disassembly of the large water column mechanism 3 and the inner shell 12.

[0083] In a preferred embodiment of the present invention, the main body of the regulating device includes a limit sleeve 41, a sliding sleeve 42 and an elastic member 43, wherein the limit sleeve 41 is detachably connected to the interior of the inner shell 12, and a limit sleeve step hole is provided inside, wherein the limit sleeve step hole is connected to the shell assembly inlet; the sliding sleeve 42 is a hollow cylinder, the upper part of which is connected to the lower part of the limit sleeve 41, and the lower part is inserted into the large water column channel, and a sliding sleeve step 421 is provided inside, wherein the interior of the sliding sleeve 42 is connected to the limit sleeve step hole to guide the gas-liquid mixture; the elastic member 43 is provided between the limit sleeve 41 and the sliding sleeve step 421, for supporting the limit sleeve 41 and providing elastic force to the sliding sleeve 42 to open or close the large water column channel.

[0084] like Figure 13-20 As shown, the limit sleeve 41 and the sliding sleeve 42 are both hollow cylindrical structures, and the elastic member 43 is a spring, preferably a compression spring, which is arranged between the limit sleeve 41 and the sliding sleeve 42 to support the limit sleeve 41 and provide elastic force for the sliding sleeve 42 to open or close the large water column channel. In this embodiment, the spring can provide a downward thrust for the sliding sleeve 42. When the large water column channel is closed, when the rotating part 40 of the rotating adjustment device and the rotating part 30 of the large water column mechanism are rotated, the spring can push the sliding sleeve 42 downward to close the large water column channel.

[0085] The step hole of the limiting sleeve is connected to the inlet of the shell assembly, and the interior of the sliding sleeve 42 is connected to the step hole of the limiting sleeve, so that the gas-liquid mixture can enter the step hole of the limiting sleeve and the interior of the sliding sleeve 42 from the inlet of the shell assembly, and enter the microbubble channel and the large water column channel through the sliding sleeve 42, wherein the sliding sleeve 42 can move up and down along the central axis of the spring.

[0086] In a preferred embodiment of the present invention, a conical shell step 211 is provided on the outer periphery of the conical shell 21, and a conical shell gasket 23 is provided on the conical shell step 211 to cooperate with the regulating device body to close the large water column channel, wherein, when the large water column channel is opened, the bottom surface of the sliding sleeve step 421 contacts the top surface of the conical shell gasket 23; when the large water column channel is closed, the bottom surface of the sliding sleeve step 421 is away from the top surface of the conical shell gasket 23.

[0087] like Figure 12 As shown, the conical shell gasket 23 corresponds to the sliding sleeve step 421; when the bottom surface of the sliding sleeve step 421 contacts the top surface of the conical shell gasket 23, the large water column channel is opened; when the bottom surface of the sliding sleeve step 421 is away from the top surface of the conical shell gasket 23, the large water column channel is closed, thereby realizing the switching of different water outlet states, and realizing the soft connection between the regulating device body and the conical shell 21, which can not only increase the sealing performance, but also reduce equipment wear and increase product life.

[0088] According to one embodiment of the present invention, the housing assembly 1 is provided with a bend for pressing the adjustment device 4 into the interior of the housing assembly 1 , wherein a limit sleeve step 411 is provided on the upper portion of the limit sleeve 41 , and the bend abuts against the limit sleeve step 411 to limit the position of the limit sleeve 41 ;

[0089] The lower part of the limiting sleeve 41 is the limiting sleeve edge 412, and the interior of the sliding sleeve 42 includes a sliding sleeve limiting hole section for connecting the limiting sleeve edge 412, wherein the limiting sleeve edge 412 is inserted into the sliding sleeve limiting hole section, and the limiting sleeve edge 412 and the sliding sleeve limiting hole section are clearance-fitted, and a limiting sleeve limiting groove 413 is provided on the limiting sleeve edge 412, and a sliding sleeve limiting protrusion 422 corresponding to the limiting sleeve limiting groove 413 is provided on the hole wall of the sliding sleeve limiting hole section to limit the limiting sleeve 41 and the sliding sleeve 42 from moving up and down.

[0090] like Figure 12-19 As shown, this embodiment can limit the position of the limiting sleeve 41 by bending and abutting against the limiting sleeve step 411, and has a simple and reasonable structure and is easy to process.

[0091] The limiting sleeve limiting groove 413 and the sliding sleeve limiting protrusion 422 can, on the one hand, restrict the limiting sleeve 41 and the sliding sleeve 42 to only move up and down, and on the other hand, can guide the limiting sleeve 41 and the sliding sleeve 42 when they are installed, so as to facilitate quick and accurate installation and improve assembly efficiency.

[0092] A limiting sleeve sealing ring 414 is provided in the middle of the limiting sleeve 41, and a sliding sleeve sealing ring 423 is provided in the middle of the sliding sleeve 42, wherein the limiting sleeve sealing ring 414 and the sliding sleeve sealing ring 423 are respectively in contact with the inner wall of the inner shell 12 to seal the gap between the inner shell 12 and the limiting sleeve 41 and the sliding sleeve 42, thereby increasing the sealing of the product and preventing water leakage.

[0093] According to one embodiment of the present invention, the large water column mechanism rotating portion 30 includes a cylinder guide rail 301 and a cylinder clamping plate 302 located on the top of the first cylinder 31, wherein the top surface of the cylinder guide rail 301 is inclined with respect to the central axis of the first cylinder 31;

[0094] The adjusting device rotating portion 40 is disposed on the outer periphery of the sliding sleeve 42 and includes a sliding sleeve guide rail 401 corresponding to the cylindrical guide rail 301 and a sliding sleeve clamping plate 402 corresponding to the cylindrical clamping plate 302. The bottom surface of the sliding sleeve guide rail 401 is inclined relative to the central axis of the sliding sleeve 42.

[0095] Among them, the cylindrical clamping plate 302 and the sliding sleeve clamping plate 402 cooperate to limit the rotation range of the sliding sleeve guide rail 401 and the cylindrical guide rail 301. The bottom surface of the sliding sleeve guide rail 401 is parallel to the top surface of the cylindrical guide rail 301. When the sliding sleeve guide rail 401 and the cylindrical guide rail 301 are in contact, the large water column channel is closed; when the sliding sleeve guide rail 401 and the cylindrical guide rail 301 are separated, the large water column channel is opened.

[0096] like Figure 17-20 The cylindrical guide rail 301, cylindrical clamping plate 302, sliding sleeve guide rail 401 and sliding sleeve clamping plate 402 shown are all arc-shaped plates. When the large water column channel is opened, the cylindrical clamping plate 302 contacts one side of the sliding sleeve clamping plate 402. When the large water column channel is closed, the cylindrical clamping plate 302 contacts the other side of the sliding sleeve clamping plate 402. The rotation range of the cylindrical guide rail 301 and the sliding sleeve guide rail 401 can be controlled by the cylindrical clamping plate 302 and the sliding sleeve clamping plate 402.

[0097] The top surface of the cylindrical guide rail 301 and the bottom surface of the sliding sleeve guide rail 401 are both arranged to be tilted upward counterclockwise along the outer circumference of the first cylinder 31, so that when the first cylinder 31 rotates, it can push the rotating part 40 of the adjustment device to rise and fall along the top surface of the cylindrical guide rail 301, thereby causing the sliding sleeve 42 to rise and fall.

[0098] In this embodiment, the number of the large water column mechanism rotating part 30 and the regulating device rotating part 40 is the same, and is no less than one, preferably two. Figure 18-19 The large water column mechanism rotating portion 30 and the regulating device rotating portion 40 are shown as two for illustration purposes only, but are not intended to limit the present invention. When the first cylinder 31 rotates clockwise, the top surface of the cylinder guide rail 301 and the bottom surface of the sleeve guide rail 401 gradually approach each other. When the top surface of the cylinder guide rail 301 and the bottom surface of the sleeve guide rail 401 contact each other, the large water column channel is closed. When the first cylinder 31 rotates counterclockwise, the distance between the top surface of the cylinder guide rail 301 and the bottom surface of the sleeve guide rail 401 gradually increases, opening the large water column channel. In this embodiment, the height travel of the sleeve guide rail 401 and the cylinder guide rail 301 is preferably 2 to 3 mm.

[0099] According to one embodiment of the present invention, the method further comprises:

A joint step groove 511 is provided at the bottom of the joint step 51, and the inner shell 12 is inserted into the joint step groove 511. The joint step 51 is threadedly connected to the limit sleeve 41.

[0101] The water outlet grille 6 is a dish-shaped disc, the top of which contacts the bottom of the second cylinder 32 and the bottom is clamped to the bottom of the shell assembly 1. A water outlet grille step is provided. The middle of the dish-shaped disc is provided with grille holes arranged in a grid for water outlet.

[0102] The filter screen 7 is located above the grille hole and is used for filtering. The outlet grille step includes a first step and a second step, and the filter screen 7 is installed on the second step.

[0103] The water outlet gasket 8 is located between the filter screen 7 and the second cylinder 32 and is installed on the first step to seal the gap between the water outlet grille 6 and the second cylinder 32.

[0104] like Figure 6-7 As shown in 16-18, the joint step 51 is provided with an internal thread, and the limiting sleeve 41 is provided with an external thread. The joint step 41 and the limiting sleeve 41 are threadedly connected to fix the adjustment device 4 to the joint 4 and thus be applicable to different water outlet mechanisms, such as a tap water pipe, a water heater outlet pipe, etc.;

[0105] The bottom of the water outlet grille 6 is installed on the outer shell step 111. The water outlet grille 6 is a disc with a circular step and regularly arranged grille holes in the middle, preferably made of plastic injection molding; the water outlet gasket 8 is made of rubber and is inserted into the first step to seal the gap between the water outlet grille 6 and the second cylinder 32, thereby improving the sealing of the product; the filter screen 7 is inserted into the second step to filter the fluid output from the large water column channel and the microbubble channel. The mesh size of the filter screen 7 is preferably 30 to 60 meshes, leaving a certain rectification space between the output end of the large water column channel and the output end of the microbubble channel and the water outlet grille 6. Combined with the filter screen 7, the microbubble water can achieve a better rectification effect.

[0106] Specific implementation process:

[0107] The water outlet grille 6, filter screen 7, water outlet gasket 8, bubble generator body 2 and large water column mechanism 3, sliding sleeve 42, elastic member 43 and limit sleeve 41 are assembled into the outer shell 11 in sequence, wherein the top surface of the cylindrical guide rail 301 is fitted with the bottom surface of the sliding sleeve guide rail 401, and the sliding sleeve limit protrusion 422 is inserted into the limit sleeve limit groove 413, so that the sliding sleeve 42 and the limit sleeve 41 cannot rotate relative to each other and can only move up and down. At the same time, the bend on the inner shell 12 is sequentially covered with the limit sleeve 41 and the sliding sleeve 42, and the bend of the inner shell 12 is pressed against the limit sleeve step 411, and the limit sleeve sealing ring 414 and the sliding sleeve sealing ring 423 are respectively connected to the inner shell 12. The inner wall of the inner shell 12 contacts to seal the gap between the inner shell 12 and the limiting sleeve 41 and the sliding sleeve 42; then the inner shell groove 121 on the inner shell 12 is clamped into the annular plate block 331 on the annular plate 33, and the inner shell 12 is threadedly connected to the outer shell 11. An inner shell sealing ring can be set between the inner shell 12 and the outer shell 11 to enhance the sealing between the inner shell 12 and the outer shell 11, and a sealing ring 127 is used for sealing. The outer shell step 111 supports the water outlet grille 6, the filter screen 7, the water outlet gasket 8 and the large water column mechanism 3. The outer shell 11 is provided with a flat cut to facilitate the use of a wrench tool to connect and fix the inner shell 12 to the outer shell 11. The joint 5 is threadedly connected to the limiting sleeve 41, and the adjusting device 4 wraps the bend of the inner shell 12, and is thus assembled into the micro-bubble generating device of the present invention. After the present invention is connected to a faucet or the like through the joint 5, water is discharged. In the present invention, the joint 5, the limiting sleeve 41, the elastic part 43, and the sliding sleeve 42 constitute a fixed module that cannot rotate around the central axis. The elastic part 43 supports the limiting sleeve 41 and the sliding sleeve 42 respectively, providing a downward thrust to the sliding sleeve 42; the shell assembly 1, the water outlet grille 6, the filter screen 7, the water outlet gasket 8, the bubble generator body 2, and the large water column mechanism 3 constitute a rotating module that can rotate around the central axis.

[0108] like Figure 16 、 18As shown, in an embodiment of the present invention, when the outer shell 11 rotates clockwise, the large water column mechanism 3 follows the forward rotation, and the elastic member 43 pushes the sliding sleeve 42 to slide downward against the top of the cylindrical guide rail 301 of the large water column mechanism 3 until the sliding sleeve guide rail 401 contacts the cylindrical guide rail 301. The sliding sleeve clamping plate 402 contacts the cylindrical clamping plate 302 below the cylindrical guide rail 301, and the outer shell 11 cannot continue to rotate, closing the large water column channel, which is the bubble block of the bubbler of the present invention and can be used to produce microbubble water from a gas-liquid mixture containing air. The microbubble channel of the present invention can release the pressure of the gas-liquid mixture to obtain microbubbles with uniform particles, small size and a large number, thereby obtaining high-quality microbubble water and effectively improving the user's water experience. A certain rectification space is left between the large water column mechanism 3 and the water outlet grid 6, and combined with the filter screen 7, the microbubble liquid achieves a better rectification effect. Since the diameter of the bubble generator body 2 is small, the water flow rate of the bubble block will be small under normal tap water pressure.

[0109] like Figure 17 、 19 As shown, in an embodiment of the present invention, when the outer shell 11 rotates counterclockwise, the bubble generator body 2 rotates in the opposite direction. The sliding sleeve 42 slides upward under the thrust of the cylindrical guide rail 301. When the sliding sleeve guide rail 401 separates from the cylindrical guide rail 301, the large water column channel can be opened. Until the sliding sleeve clamping plate 402 contacts the cylindrical clamping plate 302 above the cylindrical guide rail 301, the outer shell 11 cannot rotate in the opposite direction. At this time, the bubbler of the present invention enters the high water range. In the high water range, tap water passes through the large water column channel and the microbubble channel respectively, generating a large water flow under normal water pressure, meeting the user's large water demand.
