Description

Technical Field

[0001] The invention relates to the field of micro-nano bubble generators, and in particular to a micro-nano bubble generator and a control method thereof. Background Art

[0002] Micro-nano bubble generator is a device that can generate tiny bubbles, and the diameter of the bubbles it generates is usually between tens of nanometers and several microns. As an efficient and environmentally friendly bubble generating device, micro-nano bubble generator has broad application prospects and development potential in water treatment, agriculture, medical treatment, environmental protection and food processing.

[0003] The micro-nano bubble generator usually includes a generating device and a releasing pipe. The generating device is used to mix gas with water and generate micro-nano bubbles, while the releasing pipe is used to release the generated micro-nano bubbles into water for application. In actual use, in order to facilitate the release of bubbles into water, the length of the releasing pipe is usually long so that it can be easily extended into the water. During the transportation of micro-nano bubbles in the releasing pipe, some bubbles burst and disappear before entering the water, thereby reducing the density of the micro-nano bubbles and reducing the use effect of the micro-nano bubbles. Summary of the invention

[0004] In order to prevent the density and use effect of micro-nano bubbles from being reduced after they come out of a release pipe, the present invention provides a micro-nano bubble generator and a control method thereof.

[0005] In the first aspect, the present invention provides a micro-nano bubble generator, which adopts the following technical solution: A micro-nano bubble generator, comprising a generating device and a release pipe connected to the generating device, further comprising a diffusion head connected to the release pipe and into which micro-nano bubble water flows, and a cutting impeller rotatably installed in the diffusion head and capable of finely cutting micro-nano bubbles; The diffusion head includes a connecting seat and a diffusion cover installed on the connecting seat, a cutting chamber for installing the cutting impeller is formed between the diffusion cover and the connecting seat; the connecting seat is circumferentially provided with a spiral flow channel connecting the release pipe and the cutting chamber and in a spiral shape for water to flow through, the outlet of the spiral flow channel is inclined to point to the cutting impeller to drive the cutting impeller to rotate; the diffusion cover is circumferentially provided with diffusion holes for releasing micro-nano bubbles.

[0006] By adopting the above technical solution, when the micro-nano bubble water flows into the diffusion head from the release pipe, the cutting impeller in the diffusion head can further cut and refine the micro-nano bubble water, so that the density of the micro-nano bubbles is not easy to decrease. In addition, since the spiral flow channel is spiral and its outlet is inclined to point to the cutting impeller, the cutting impeller can be driven to rotate when the micro-nano bubble water flows out of the connecting seat. In the case where it is difficult to install a motor in the diffusion head, the cutting impeller can also rotate without the drive of an electric drive source, thereby reducing the volume and structure of the diffusion head.

[0007] Optionally, the diffusion cover comprises an outer cover fixedly mounted on the connecting seat and an inner cover located inside the outer cover and rotatably mounted on the connecting seat, wherein both the inner cover and the outer cover have diffusion holes; and a connecting assembly for driving the inner cover to rotate is connected to the cutting impeller; The connecting assembly comprises a driving wheel sleeved on the cutting impeller, a circumferential wheel circumferentially meshed with the outer side of the driving wheel and rotating, and an inner tooth portion connected to the inner wall of the inner cover and meshed with the circumferential wheel.

When the micro-nano bubbles are released from the inner cover through the outer cover, the inner cover can also cut the micro-nano bubbles.

[0009] Optionally, the circumferential wheel includes an inner ring shaft portion, an outer ring tooth portion, and a connecting portion circumferentially arranged therebetween and connecting the two; a water passage groove is formed between adjacent connecting portions for water to pass through and be released from the diffusion hole of the inner cover.

[0010] By adopting the above technical solution, the circumferential wheel is a component connecting the inner cover and the cutting impeller, and the cutting impeller can drive the inner cover to rotate synchronously through the circumferential wheel. In addition, due to the setting of the connecting part in the circumferential wheel structure, the micro-nano bubble water can flow through the water-passing grooves. When the cutting impeller drives the inner cover to rotate, the circumferential wheel also rotates. At this time, the connecting part can be regarded as an impeller, and can also cut the micro-nano bubble water passing through it.

[0011] Optionally, the cutting impeller has a rotating shaft, the rotating shaft is rotatably connected to the connecting seat, a rotating bearing and a sealing mechanism for preventing water from entering the rotating bearing are arranged between the rotating shaft and the connecting seat; the connecting seat is provided with an installation groove for installing the rotating bearing; The sealing mechanism includes a static mold cover installed on the connecting seat and pressing the rotating bearing against the mounting groove, a dynamic mold ring sleeved on the rotating shaft and slidingly frictionally sealed with the static mold cover, a fixed seat sleeved on the outer side of the dynamic mold ring and locking the dynamic mold ring to the rotating shaft, and a compression spring sleeved on the rotating shaft and pressing the dynamic mold ring against the static mold cover.

[0014] By adopting the above technical solution, before the diffuser head enters the water, the energy storage mechanism is manually charged, so that after the diffuser head enters the water, the cutting impeller is pre-rotated under the action of the energy storage coil spring, so that the micro-nano bubble water drives the cutting impeller to rotate, avoiding the situation where the micro-nano bubble water cannot drive the cutting impeller to start rotating.

[0015] Optionally, a sealed chamber is provided between the outer cover and the inner cover, and the energy storage coil spring is provided in the sealed chamber; a damping assembly is also provided in the sealed chamber for applying damping to the drive shaft to slowly release the energy of the energy storage coil spring, and the damping assembly includes a damping ring circumferentially arranged on the inner wall of the sealed chamber, a mounting ring sleeved and fixed on the drive shaft, a damping block telescopically mounted on the mounting ring, and a driving spring that drives the damping block to extend out of the mounting ring and abut against the damping ring.

[0016] By adopting the above technical solution and providing a damping assembly, the energy of the energy storage coil spring can be slowly released, so that the cutting impeller can pre-rotate for a longer time.

[0018] By adopting the above technical solution, when it is detected that the diffusion hole is covered, the system can control the blocking ring to close the covered diffusion hole, so that the micro-nano bubble water will not flow to the closed diffusion hole, and can be released from the unobstructed diffusion hole, effectively maintaining the density of the micro-nano bubbles.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The embodiment of the present application discloses a micro-nano bubble generator.

[0026] Reference Figure 1 A micro-nano bubble generator includes a generating device 1, a releasing pipe 2 and a diffusion device 3. The generating device 1 is used to generate micro-nano bubble water, the releasing pipe 2 is connected to the generating device 1 to transport the micro-nano bubble water, and the diffusion device 3 is connected to the releasing pipe 2 to process the micro-nano bubble water coming out of the releasing pipe 2 before releasing it.

[0027] Reference Figure 1 and Figure 2 The diffusion device 3 includes a diffusion head 31 connected to the release pipe 2 and a cutting impeller 32 installed in the diffusion head 31. The diffusion head 31 is used for the micro-nano bubble water to flow in, and the cutting impeller 32 is used for finely cutting the micro-nano bubbles in the diffusion head 31.

[0028] Reference Figure 2 and Figure 3The diffusion head 31 includes a diffusion cover 311 and a connection seat 312. The connection seat 312 is a cylinder, which is connected to the end of the release pipe 2 through a connection structure. The diffusion cover 311 includes an inner cover 3111 and an outer cover 3112 located outside the inner cover 3111, the outer cover 3112 is fixedly installed on the connection seat 312, the side wall of the inner cover 3111 is rotatably installed on the connection seat 312, and the bottom wall of the inner cover 3111 is fixedly connected to the outer cover 3112. There is a certain gap between the inner cover 3111 and the outer cover 3112, and a cutting chamber 3113 is formed around the inner cover 3111 and the connection seat 312, and diffusion holes 3114 for releasing micro-nano bubble water are provided on the inner cover 3111 and the outer cover 3112.

[0029] In order to allow the micro-nano bubble water to enter the cutting chamber 3113 from the release pipe 2 through the connecting seat 312, a plurality of spiral flow channels 3121 are opened circumferentially on the connecting seat 312, the spiral flow channels 3121 connect the release pipe 2 and the cutting chamber 3113, and the spiral flow channels 3121 are spiral-shaped, and their outlets are arranged at an angle.

[0030] The cutting impeller 32 is rotatably mounted in the cutting chamber 3113, and can further cut and refine the micro-nano bubbles entering the cutting chamber 3113. The cutting impeller 32 has a rotating shaft 321, which is coaxially rotatably mounted at the center of the connecting seat 312, and the outlet of the spiral flow channel 3121 is tilted to point to the cutting impeller 32. When the micro-nano bubble water flows out of the spiral flow channel 3121, it can impact on the cutting impeller 32, thereby driving the cutting impeller 32 to rotate without the drive of an electric power source.

[0031] Reference Figure 2 and Figure 3 , further, the inner cover 3111 and the cutting impeller 32 can rotate synchronously, and the cutting impeller 32 is connected to a connecting assembly 33 that drives the inner cover 3111 to rotate. The connecting assembly 33 includes a driving wheel 331, a circumferential wheel 332 and an inner tooth portion 333. Among them, the driving wheel 331 is sleeved and fixed on the cutting impeller 32, the circumferential wheel 332 is circumferentially meshed with the outer side of the driving wheel 331, and the shaft of the circumferential wheel 332 is fixed to the bottom wall of the inner cover 3111 so that the circumferential wheel 332 can rotate when the driving wheel 331 rotates, and the inner tooth portion 333 is connected to the side wall of the inner cover 3111 and meshed with the outer side of the circumferential wheel 332. When the driving wheel 331 rotates, the inner tooth portion 333 can drive the inner cover 3111 and the cutting impeller 32 to rotate synchronously.

[0032] Furthermore, the diameter of the driving wheel 331 is smaller than the diameter of the circumferential wheel 332, so that the rotation speed of the inner cover 3111 is much lower than the rotation speed of the cutting impeller 32. When the cutting impeller 32 cuts the micro-nano bubbles at high speed, the inner cover 3111 and the outer cover 3112 can also rotate relatively slowly, so that the micro-nano bubbles can also be cut when passing through the outer cover 3112 from the inner cover 3111.

[0033] Reference Figure 2 and Figure 3 Further, in this embodiment, the number of the circumferential wheels 332 is four, and the bottom wall of the inner cover 3111 is covered with the maximum coverage area. The circumferential wheel 332 includes an inner ring shaft portion 3321, an outer ring tooth portion 3322, and a connecting portion 3323 circumferentially arranged between the two and connecting the two, and a water-passing groove 3324 is formed between adjacent connecting portions 3323. The micro-nano bubble water can pass through the inner cover 3111 and the outer cover 3112 through the water-passing groove 3324 to be released, and because the circumferential wheel 332 can rotate, the connecting portion 3323 can also cut the micro-nano bubble water passing through, so that the micro-nano bubbles are cut.

[0034] Reference Figure 2 and Figure 4 A rotating bearing 34 is arranged between the rotating shaft 321 of the cutting impeller 32 and the connecting seat 312, so that the cutting impeller 32 can rotate more smoothly. The connecting seat 312 has a mounting groove 3122 circumferentially formed on the rotating shaft 321, and the rotating bearing 34 is installed in the mounting groove 3122.

[0035] Furthermore, in order to prevent the rotating bearing 34 from rusting, a sealing mechanism 35 is provided on the rotating shaft 321 to prevent water from entering the rotating bearing 34. The sealing mechanism 35 includes a static mold cover 351, a dynamic mold ring 352, a fixed seat 353 and a pressing spring 354. The static mold cover 351 has an L-shaped cross section, which is fixedly installed on the connecting seat 312 and presses the rotating bearing 34 against the mounting groove 3122. The static mold cover 351 performs a sealing process between the connecting seat 312. The fixed seat 353 is sleeved on the rotating shaft 321 and can rotate with the rotating shaft 321. The dynamic mold ring 352 is annular and sleeved and fixed on the outer side of the rotating shaft 321, one end of which abuts against the static mold cover 351, and the other end is fixed to the fixed seat 353. When the dynamic mold ring 352 and the fixed seat 353 rotate synchronously with the rotating shaft 321, sliding friction is generated between the dynamic mold ring 352 and the static mold cover 351, so that sliding friction sealing can be performed.

[0036] The clamping spring 354 is sleeved on the outer side of the rotating shaft 321 , one end of which abuts against the fixing seat 353 , and the other end abuts against the cutting impeller 32 . The clamping spring 354 can lock the movable die ring 352 on the static die seat.

[0037] Reference Figure 2and Figure 5 When the diffusion device 3 enters the water, the cutting impeller 32 may not be easy to start under the drive of the micro-nano bubble water, and the diffusion cover 311 is provided with an energy storage mechanism 36 that can drive the cutting impeller 32 to pre-rotate. A sealed chamber 3115 is provided between the bottom wall of the outer cover 3112 and the bottom wall of the inner cover 3111, and the energy storage mechanism 36 is provided in the sealed chamber 3115.

[0038] Combination Figure 2 , Figure 5 and Figure 6 The energy storage mechanism 36 includes an energy storage coil spring 361 and a drive shaft 362. One end of the drive shaft 362 passes through the bottom of the inner cover 3111 and is rotatably connected to the cutting impeller 32. The other end of the drive shaft 362 passes through the outer cover 3112 and is connected to a hand-tightening portion 363. A one-way rotating component 364 is provided between the drive shaft 362 and the cutting impeller 32. The one-way rotating component 364 is a prior art and is not described in detail herein.

[0039] The energy storage coil spring 361 is sleeved on the outside of the driving shaft 362 , one end of which is fixed to the driving shaft 362 , and the other end of which is connected to the inner wall of the sealed chamber 3115 .

[0040] When the diffuser head 31 enters the water, the drive shaft 362 is rotated by the hand-tightening part 363, at which time the energy storage coil spring 361 can store power, and the drive shaft 362 can rotate along the positive direction of the one-way rotating component 364 without driving the cutting impeller 32 to rotate. When the diffuser head 31 completes power storage, the energy storage reel starts to release energy, and the drive shaft 362 rotates in the reverse direction of the one-way rotating component 364. At this time, the drive shaft 362 drives the one-way rotating component 364 to rotate, and the one-way rotating component 364 rotates synchronously with the cutting impeller 32.

[0041] Combination Figure 2 , Figure 5 and Figure 6 Furthermore, a damping assembly 37 is also provided in the sealed chamber 3115 to apply damping to the drive shaft 362 to slowly release the energy of the energy storage coil spring 361. The damping assembly 37 includes a damping ring 371, a mounting ring 372, a damping block 373 and a driving spring 374. The damping ring 371 is annular and circumferentially arranged on the inner wall of the sealed chamber 3115. The surface of the damping ring 371 is relatively rough and has greater friction. The mounting ring 372 is fixedly sleeved on the outer side of the drive shaft 362. The damping block 373 is telescopically installed on the mounting ring 372, and the driving spring 374 is installed in the mounting ring 372 and can drive the damping block 373 to extend from the mounting ring 372 and abut against the damping ring 371.

[0042] When the drive shaft 362 rotates due to the release of energy from the energy storage coil spring 361 , the damping block 373 extends from the mounting ring 372 due to the centrifugal force and is pressed against the damping ring 371 , so that the drive shaft 362 can slowly consume energy.

[0043] Based on the same inventive concept, an embodiment of the present invention provides a control method for a micro-nano bubble generator, which obtains the tilt posture information of the diffusion head 31 to determine whether the diffusion hole 3114 of the diffusion head 31 is blocked, and the diffusion head 31 is processed with different processing methods according to different blocking positions. In order to enable the diffusion head 31 to enter the water in a better posture for operation, the diffusion head 31 after entering the water is adjusted in real time through the tilt posture information and the blocking ring.

[0044] Reference Figure 7 , a control method for a micro-nano bubble generator comprises the following steps: Step S100 : obtaining the tilt posture information of the diffusion head 31 .

[0045] The tilt posture information here refers to the posture of the diffusion head 31 after it is placed underwater, including the tilt angle and tilt direction. The diffusion head 31 may be placed tilted or vertically at the bottom of the water, and different placement methods will have different effects on the diffusion head 31. The diffusion head 31 has a tilt sensor inside, and the tilt posture information of the diffusion head 31 can be obtained and analyzed by the tilt sensor.

[0046] Step S101: determining whether the diffusion head 31 is placed tilted or vertically based on a comparison relationship between the tilt posture information of the diffusion head 31 and a preset vertical angle.

[0047] The preset vertical angle is the standard value measured when the tilt sensor is vertical, and will not be described in detail here.

[0048] By comparing the tilt posture information of the diffusion head 31 measured by the tilt sensor with the vertical angle, it is determined whether the state of the diffusion head 31 at the bottom of the water is a tilted state or a vertical state. When the diffusion head 31 is in a tilted state, the diffusion holes 3114 on the circumferential side walls of the outer cover 3112 of the diffusion head 31 may be covered and blocked by substances existing at the bottom of the water; and when the diffusion head 31 is in a vertical state, the diffusion holes 3114 at the bottom of the outer cover 3112 of the diffusion head 31 may be covered and blocked by substances existing at the bottom of the water. When the diffusion holes 3114 are covered, a part of the micro-nano bubbles will hit the covered diffusion holes 3114 and disappear, thereby affecting the density of the released micro-nano bubbles.

[0049] Step S102: Based on the fact that the diffusion head 31 is tilted, the lower position of the diffusion head 31 is determined according to the tilt posture information, and the diffusion hole 3114 at the lower position is scanned to obtain the outflow distance.

[0050] The lower position refers to the side wall position of the outer cover 3112 below the diffusion head 31 when the diffusion head 31 is placed at an angle. The diffusion hole 3114 at this position may be covered, and it is necessary to scan this position to determine whether it is covered.

[0051] The outflow distance refers to the distance from the photoelectric sensor setting position to the position where the light is reflected in the diffusion hole 3114, which is obtained by the photoelectric sensor preset in the diffusion head 31. The photoelectric sensor is set at the center of the diffusion head 31, and the distance between it and each diffusion hole 3114 inside the diffusion head 31 is equal. When the diffusion hole 3114 is covered, the light emitted by the photoelectric sensor is reflected at the position of the diffusion hole 3114, so the outflow distance is a fixed value, and when the diffusion hole 3114 is unobstructed, the light emitted by the photoelectric sensor can penetrate the diffusion hole 3114, so the outflow distance is greater than the fixed value.

[0052] Step S103: determining whether the diffusion hole 3114 is blocked or unblocked based on a comparison relationship between the outflow distance and a preset standard distance.

[0053] The preset standard distance is a value set by technicians based on the size standard of the diffusion head 31, which is the distance from the light emitted by the photoelectric sensor to the position of the diffusion hole 3114, and will not be elaborated here.

[0054] If the outflow distance is greater than the standard distance, it means that the diffusion hole 3114 is unblocked. If the outflow distance is equal to the standard distance, it means that the diffusion hole 3114 is blocked.

[0055] Step S104: Based on the blockage of the diffusion hole 3114 , the blockage range and blockage position of the outer cover 3112 are determined according to the blocked diffusion hole 3114 obtained by scanning.

[0056] The blocking range refers to the range formed by all blocked diffusion holes 3114 on the outer cover 3112 , and the blocking position refers to the position of the blocking range on the outer cover 3112 .

[0057] When the photoelectric sensor determines which diffusion holes 3114 on the diffusion head 31 are blocked, the range formed by all blocked diffusion holes 3114 on the outer cover 3112 and the position of the range of the blocked diffusion holes 3114 on the diffusion head 31 can be determined based on the blocked diffusion holes 3114 .

[0058] Step S105 : controlling the preset blocking ring to rotate to cover the blocked diffusion holes 3114 according to the blocking range and blocking position to control the release of micro-nano bubbles from the unblocked diffusion holes 3114 .

[0059] The blocking ring is used to close the diffusion holes 3114 on the outer cover 3112 so that the micro-nano bubbles will not flow to the closed diffusion holes 3114. In this embodiment, the inner wall of the outer cover 3112 is circumferentially provided with a blocking ring, the circumferential angle of the blocking ring is about 120 degrees, and the blocking ring is composed of grid bars arranged at intervals and connecting bars connecting the grid bars. When the diffusion holes 3114 are not covered, the grid bars of the blocking ring are located between two adjacent diffusion holes 3114. The blocking ring has a magnetic block at the bottom of the connecting bar, and the diffusion head 31 is provided with a driving device on the connecting seat 312 to drive the magnetic block to slide circumferentially along the diffusion head 31.

[0060] After the blocking range and blocking position are determined, the blocking ring is controlled to rotate until the diffusion ring at the blocking position is closed. The method of controlling the blocking ring is not described here in detail and will be introduced in the subsequent scheme.

[0061] Reference Figure 8 , the control method of the blocking ring includes the following steps: Step S200: Determine the location of the positioning center point according to the blockage location.

[0062] The positioning center point position refers to the center point position of the blocking position in the direction of the connecting seat 312. The center point between the two ends of the blocking range in the horizontal direction can be determined, and the center point is the positioning center point position. The center point position is used for positioning the blocking ring. When the magnetic block of the blocking ring moves to the positioning center point position, the blocking ring can close the diffusion hole 3114 at the blocking position.

[0063] Step S201: determining a moving path and a path distance therebetween according to the location of the positioning center point and the preset magnetic block location.

[0064] The preset magnetic block position refers to the initial position of the blocking ring and the magnetic block. The initial position is a fixed position set by a technician for arranging the blocking ring, which will not be described in detail here.

[0065] The moving path refers to the path that the magnet moves from the magnet position to the positioning center point position. The path distance refers to the length of the moving path. A coordinate system is established with the center of the diffusion head 31 as the origin, and the preset magnet position is a fixed position point in the coordinate system. The positioning center point position can also determine its position in the coordinate system based on the tilt posture information. Therefore, by taking the center of the diffusion head 31 as the center of the circle, the path distance of the arc moving path from the magnet position to the positioning center point position can be calculated.

[0066] Step S202: Determine the magnetic strength provided by the driving device according to the path distance.

[0067] When the positioning center point is determined, the driving device can generate a magnetic force at the position according to the coordinates of the positioning center point, and use the magnetic force to attract the magnetic block carrying the blocking ring to move to the positioning center point. The magnetic force strength required for the driving device to attract the magnetic block to move is related to the distance from the positioning center point to the magnetic block position. Therefore, the magnetic force strength that the driving device needs to generate at the positioning center point is determined according to the path distance.

[0068] Step S203: Control the driving device to release the magnetic force at the positioning center point to attract the magnetic block and the blocking ring to move along the moving path to the positioning center point and cover the blocked diffusion hole 3114.

[0069] After determining the location of the positioning center point and the strength of the magnetic force, a driving device generates a magnetic force at the location of the positioning center point to attract the blocking ring to the location of the positioning center point, so that the blocked diffusion hole 3114 can be closed by the blocking ring.

[0070] Reference Fig. 9 The diffusion head 31 may be in a vertical arrangement state when it is at the bottom of the water. The adjustment method for blocking the diffusion hole 3114 when the diffusion head 31 is placed vertically includes the following steps: Step S300: Based on the diffusion head 31 being placed vertically, the diffusion hole 3114 at the bottom of the diffusion head 31 is scanned to obtain the outflow distance.

[0071] Similar to step S102, the outflow distance is obtained by a photoelectric sensor. The outflow distance here is the distance from the photoelectric sensor setting position to the position where the light is reflected in the diffusion hole 3114 at the bottom of the diffusion head 31, which will not be described in detail here.

[0072] Step S301: determining whether the diffusion hole 3114 is blocked or unblocked based on a comparison between the outflow distance and the standard distance.

[0073] The process is the same as step S103 and will not be described in detail here.

[0074] Step S302 : Based on the blockage of the diffusion hole 3114 , the telescopic support rods preset at the four corners of the bottom of the diffusion head 31 are controlled to extend with a preset extension length to prop up the diffusion head 31 , and the tilt posture information of the diffusion head 31 is obtained again.

[0075] In this embodiment, a telescopic support rod capable of telescopic movement is circumferentially arranged at the bottom of the diffusion head 31, and the length of the telescopic support rod can also be adjusted. When the bottom of the diffusion head 31 is covered, the diffusion head 31 is propped up by extending the telescopic support rod, so that a gap is generated between the bottom of the diffusion head 31 and the bottom of the water. At this time, the diffusion head 31 at the bottom is unobstructed.

[0076] The preset extension length is a reference value set by a technician. On a flat surface, the telescopic support rod is extended by the extension length to support the diffusion head 31. If the surface on which it is placed is uneven, the diffusion head 31 needs to adjust the length of the telescopic support rod later, which will not be described in detail here.

[0077] When the photoelectric sensor determines that the diffusion hole 3114 at the bottom of the diffusion head 31 is covered, the telescopic support rod is first extended to a certain length to support the diffusion head 31, and then a check is made to see whether the diffusion head 31 is vertical as a whole after being supported. If it is not vertical, vertical adjustment is required to prevent the diffusion head 31 from tipping over easily. At this time, the inclination posture information of the diffusion head 31 needs to be obtained again through the inclination sensor.

[0078] Step S303: determining whether the adjustment is completed or the angle adjustment is performed based on the comparison relationship between the tilt posture information of the diffusion head 31 and the vertical angle.

[0079] When the tilt posture information is consistent with the vertical angle, it means that the diffuser head 31 is still in a vertical state after being supported by the telescopic support rod, and there is no need to adjust the angle of the diffuser head 31. When the two are inconsistent, it means that the diffuser head 31 is tilted after being supported by the telescopic support rod, and the length of the telescopic support rod needs to be adjusted to adjust the angle relative to the diffuser head 31.

[0080] Step S304: Based on the angle adjustment, the telescopic adjustment amount of the telescopic support rod is determined according to the tilt posture information.

[0081] The telescopic adjustment amount refers to the amount required to adjust the length of the telescopic support rod so that the diffusion head 31 is placed vertically.

[0082] When adjusting the angle, the tilt posture information of the diffuser head 31 can be used to determine at which position of the bottom of the diffuser head 31 the extended length of the telescopic support rod is too long or too short. On this basis, the telescopic adjustment amount of the telescopic support rod is calculated based on the angle information in the tilt posture information and the size of the diffuser head 31 itself.

[0083] Step S305: controlling the telescopic support rod to be telescopic according to the telescopic adjustment amount so that the diffusion head 31 is placed vertically.

[0084] After determining which telescopic support rods need to be adjusted and the telescopic adjustment amount, control the telescopic support rods to make adjustments.

[0085] Reference Fig.10 In order to make the diffusion head 31 maintain a good vertical posture in the water to release micro-nano bubbles, the diffusion head 31 needs to start posture control when entering the water. The method for controlling the posture of the diffusion head 31 includes the following steps: Step S400: Obtaining the tilt posture information of the diffuser head 31 when entering the water.

[0086] The tilt posture information here refers to the posture of the diffuser head 31 when entering the water. The specific method is the same as step S100 and will not be repeated here.

[0087] Step S401: determining the lower position of the diffusion head 31 according to the tilt posture information.

[0088] The method for determining the lower position is the same as that in step S102 and will not be described in detail here.

[0089] Step S402: determining the lower center point position according to the lower position, and determining the balance distance between the lower center point position and the magnetic block position.

[0090] The lower center point position refers to the center point position of the lower position in the direction of the connecting seat 312, and the balance distance is the length of the arc distance between the lower center point position and the magnetic block position with the center of the diffusion head 31 as the center of the circle.

[0091] The method for determining the lower center point position and the balance distance is the same as that in step S200 and step S201, and will not be described in detail here.

[0092] Step S403: determining the magnetic strength provided by the driving device according to the balance distance.

[0093] The method for determining the lower position is the same as that in step S202 and will not be described in detail here.

[0094] Step S404: Control the driving device to release the magnetic force at the lower center point, attract the magnetic block and the blocking ring to move to the lower center point and cover the diffusion hole 3114 at the lower position to generate reverse thrust, and obtain the tilt posture information of the diffusion head 31 again.

[0095] When the diffuser head 31 enters the water, after the tilt sensor determines that it is tilted and determines the tilt direction, the blocking ring is moved to the lower position of the diffuser head 31 when it is tilted through the driving device. At this time, no micro-nano bubbles will be released at the lower position, while bubbles will be released at the opposite side of the lower position, thereby generating thrust on the side with bubble release, and the diffuser head 31 can have a tendency to reset to a vertical posture.

[0096] After the blocking ring is adjusted by the driving device, the posture of the diffusion head 31 will change. At this time, the posture of the diffusion head 31 needs to be adjusted again to see whether the posture of the diffusion head 31 is adjusted in place.

[0097] Step S405: determining whether the adjustment is completed or readjusted according to the comparison relationship between the tilt posture information of the diffusion head 31 and the vertical angle.

[0098] When the tilt posture information of the diffuser head 31 is consistent with the vertical angle, it means that the posture adjustment of the diffuser head 31 entering the water is completed, and the diffuser head 31 is in a vertical position. If the two are inconsistent, it means that the diffuser head 31 needs to continue to adjust and obtain the posture until the diffuser head 31 is in a vertical position.

[0099] The diffusion head 31 lands in a vertical posture and can be subsequently adjusted by a telescopic support rod. The diffusion holes 3114 around the diffusion head 31 can release micro-nano bubbles.

[0100] Step S406: Based on the completion of the adjustment, the driving device is controlled to release the magnetic force circumferentially at a preset rotation speed and in a preset running light manner to control the circumferential rotation of the blocking ring.

[0101] The preset rotation speed refers to the speed at which all positions on the driving device that can generate magnetic force rotate to generate magnetic force. The preset running light mode refers to all positions on the driving device that can generate magnetic force generating magnetic force in a running light mode. Specifically, in order to enable the blocking ring to rotate in a circle, the positions on the driving device that can generate magnetic force rotate at intervals in the circumferential direction.

[0102] When the diffusion head 31 has been adjusted to a vertical posture when entering the water, in order to prevent the diffusion head 31 from tilting again, the driving device drives the blocking ring to rotate circumferentially at a preset rotation speed and a preset water flow lamp mode, so that the diffusion head 31 is always in the adjustment process.

[0103] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
