Description

Technical Field

[0001] This invention relates to the field of sprinkler irrigation technology, and more particularly to a foldable and rotating sprinkler irrigation device. Background Technology

[0002] Sprinkler irrigation equipment delivers pressurized water, either by a pump or due to natural drop, through pressurized pipelines to the fields. The water is then sprayed into the air via nozzles, forming fine droplets that are evenly distributed across the farmland to achieve irrigation. In my country, the most commonly used types include: fixed-pipe systems, semi-mobile systems, large-scale mobile systems, and sprinkler units. Fixed-pipe systems are expensive; semi-mobile systems require significant manpower; large-scale mobile systems are demanding in terms of terrain and environment, are difficult to maneuver, have high technical requirements, are cumbersome to operate, and are prone to collisions with obstacles such as utility poles and trees, resulting in low safety; sprinkler units are generally sprinkler trucks, but current technology only sprays the fields on either side of the truck, requiring the vehicle to travel on relatively wide field roads. This limits their effectiveness in irrigating contiguous fields with narrow roads. Summary of the Invention

A water outlet pipe is fixedly connected to the middle of the water supply pipe along its length. The water outlet pipe is vertically arranged, with a solenoid valve at its top opening to control its opening and closing. When the side frame mechanism is not installed, a spraying device is installed at the top opening of the water outlet pipe. The spraying operation is simple; the water supply pipe has two fixed frames running through its internal space at both ends; each fixed frame has four vertically arranged first shaft cylinders fixed on its front and rear sides, the four first shaft cylinders are distributed at the four corners of the fixed frame, and the two first shaft cylinders on the same side are coaxially arranged. The first shaft cylinders are hollow cylinders and are fixed by pins, so that the side frame mechanism can rotate along the first shaft cylinder on one side of the fixed frame; the lower tower and the upper tower are fixed to the top and bottom of the main square frame, respectively. Both the lower tower and the upper tower are pyramidal rigid frame structures. The upper tower has a traction seat fixed at the top center. The traction seat is a rigid square plate and is used to fix the traction rope; the lower tower has a driven seat fixed at the bottom center. The driven seat is a horizontally arranged ring.

[0007] Preferably, the base frame mechanism includes a base frame body, a water inlet pipe, and wheels; the base frame body includes a horizontally arranged crossbeam and vertically arranged pillars on both sides of the crossbeam, the tops of the two pillars are fixedly connected to both ends of the crossbeam, and the bottoms of the two pillars are respectively fixed with horizontally arranged cross columns, which are perpendicular to the crossbeam. Each cross column has wheels rotatably connected to both ends; the wheels are electrically connected to a power supply mechanism, and the wheels drive the equipment forward or backward through motor control; the cooperation between the base frame body and the wheels is used to control the movement of the entire equipment; a rotating mechanism is fixedly arranged above the center of the crossbeam along its length, a power supply mechanism is fixedly arranged below the crossbeam, and a water inlet pipe is fixedly arranged at the center of the crossbeam along its length below the crossbeam. The water inlet pipe is an L-shaped pipe, and the end of the water inlet pipe away from the base frame body is parallel to the ground.

[0008] Preferably, the rotating mechanism includes a rotating base and a driving component, the driving component being electrically connected to a power supply mechanism; the driving component has a built-in motor, the rotating base is fixed to the top of the driving component, the output end of the driving component is rotatably connected to the bottom of the rotating base, and the driving component is used to drive the rotating base to rotate around its own axis; a vertical pipe interface is coaxially provided at the center of the rotating base, the pipe interface being a vertically arranged pipe, the top of the inlet pipe passing through the driving component and rotatably connected to the bottom of the pipe interface, the internal spaces of the two being interconnected, and the connection between the top of the inlet pipe and the bottom of the pipe interface being a dynamic seal contact; the top of the pipe interface is detachably rotatably connected to the bottom of the outlet pipe, the internal spaces of the two being interconnected, and the connection between the bottom of the outlet pipe and the top of the pipe interface being a dynamic seal contact; the rotating base and the driven base are adapted to each other at their annular center, and after the two are engaged, when the rotating base rotates, it can drive the driven base to rotate, and then the driven base drives the main frame mechanism to rotate as a whole, thereby the main frame mechanism controls the rotation of the side frame mechanism.

[0009] Preferably, the side frame mechanism includes a movable frame, a spray pipe, an extension rod, and a tripod. The size of the movable frame is adapted to the size of the fixed frame. When the side frame mechanism is fully extended, the opposite surfaces of the movable frame and the fixed frame are in contact. Two coaxially vertically arranged second shaft cylinders are fixed on the front and rear sides of the movable frame, respectively. The second shaft cylinders are adapted to the first shaft cylinders, allowing the user to simultaneously insert a pin into both the first and second shaft cylinders on the same side, thus hinged the main frame mechanism and the side frame mechanism. The spray pipe is a horizontally arranged rigid straight pipe, perpendicular to the end face of the movable frame away from the main mechanism. The spray pipe has the same diameter as the water supply pipe. When the side frame mechanism is fully extended, the spray pipe can be connected to the water supply pipe, allowing liquid to enter the spray pipe from the water supply pipe. A spray nozzle is fixed at the bottom of the spray pipe. The nozzle is a spray head connected to the inside of the spray pipe, used to spray the liquid inside the spray pipe onto the ground; there are multiple nozzles, evenly distributed along the length of the spray pipe; a solenoid valve is provided at the end of the spray pipe away from the movable frame, used to control the liquid flow; there are two extension pipes, arranged parallel to the spray pipe, with one end fixedly connected to the movable frame; a tripod is provided between the two extension pipes and the spray pipe, the tripod being a triangular frame, with its three vertices fixed to the outer surfaces of the two extension pipes and the spray pipe respectively, used for the combination of the tripod and the extension pipe to fix and support the spray pipe; multiple tripods are evenly distributed along the length of the spray pipe; the end of the pull rope away from the pull seat is fixed to the top of a tripod away from the main frame mechanism.

[0010] Preferably, the main frame mechanism has multiple side frame mechanisms on both sides, and the multiple side frame mechanisms are connected along their length direction. The spray pipes of each side frame mechanism are internally connected, and each side frame mechanism in the same length direction is hinged to each other.

[0011] Preferably, the bottom of the water supply pipe is fixedly connected to two first bend pipes, and the two first bend pipes are respectively fixed at both ends of the water supply pipe near the fixed frame. The first bend pipes are arc-shaped pipes, and the connection points between the two first bend pipes and the water supply pipe are each fixed with a solenoid valve for controlling the flow of liquid.

[0012] The bottom of the spray pipe is fixed with a second bend pipe, which is located at the end of the spray pipe near the movable frame. The second bend pipe is an arc-shaped pipe.

[0013] A connecting pipe is detachably and fixedly connected between the openings of adjacent first and second bend pipes. The connecting pipe is made of a soft material, and the connecting pipe enables communication between the first and second bend pipes.

[0014] Preferably, the connecting second bend pipe and the first bend pipe are detachably fixed with connecting pieces on the same side, and an active magnet is fixed between the two connecting pieces. Each of the two connecting pieces is fixedly connected to an active magnet. The connecting piece is a rectangular plate-shaped magnetic block or a rectangular soft sheet made of elastic rubber. One side of the active magnet faces the connecting pipe.

[0015] Multiple passive magnet assemblies are fixed on the outer surface of the connecting tube near the active magnet. The multiple passive magnet assemblies are evenly distributed along the length of the connecting tube, and the passive magnet assemblies and the opposite surfaces of the active magnet can magnetically attract each other.

[0016] The elasticity of the connecting piece is less than that of the connecting tube, allowing the connecting tube to deform towards the passive magnet assembly under the attraction of the active magnet.

[0017] Preferably, a paraffin film is coaxially disposed inside the connecting tube. The paraffin film is a tubular elastic membrane fixed to the inner side of the inner wall of the connecting tube. A paraffin cavity is formed between the paraffin film and the inner wall of the connecting tube. The paraffin cavity is a closed cavity. The paraffin cavity is filled with paraffin.

[0018] A temperature control component is fixed to one side of the first bend pipe, and a heating wire is fixedly extended from the temperature control component. The heating end of the heating wire passes through the first bend pipe and enters the paraffin cavity to heat and soften the paraffin. The temperature control component is used to control the temperature of the heating wire.

[0019] The passive magnet assembly includes a passive magnetic block and a passive membrane. The magnetic pole face of the passive magnetic block faces the active magnet. The passive magnetic block is a permanent magnet. The passive membrane is an elastic soft membrane protruding from the surface of the connecting tube. The passive membrane, the passive magnetic block, and the outer surface of the connecting tube form a shaping cavity. The shaping cavity is a cavity body and is connected to the paraffin cavity, allowing paraffin to enter the shaping cavity.

[0020] Multiple separators are fixed inside the paraffin cavity. The separators are long, elastic, soft membranes with their length parallel to the length of the connecting tube. One side of the separator is fixedly connected to the paraffin membrane, and the other side is connected to the inner wall of the connecting tube. The separators are evenly distributed around the axial direction of the paraffin membrane to divide the paraffin cavity into multiple independent cavities in the radial direction, thereby preventing the paraffin from accumulating at the bottom of the paraffin cavity due to gravity when it softens.

[0021] Preferably, the active magnet is a DC electromagnet, and a magnetic control component is fixed on one side of the second bent pipe. The magnetic control component is electrically connected to the active magnet and is used to control the magnitude and direction of the current flowing through the active magnet, thereby controlling the magnitude of the magnetic force and the direction of the magnetic poles of the active magnet.

[0022] The two partition membranes adjacent to the shaping cavity are heat insulation membranes. The heat insulation membranes are made of elastic material that can insulate against heat. The two heat insulation membranes divide the paraffin cavity into left and right parts radially. Each part is equipped with an independent heating wire. The paraffin in the part connected to the shaping cavity is low-melting-point paraffin, and its melting point is lower than that of the paraffin on the side away from the shaping cavity. When the connecting tube is bent, the paraffin is cooled and solidified by the liquid flow. At this time, the heating wire near the shaping cavity is heated separately, so that the paraffin inside the part connected to the shaping cavity melts. At the same time, the magnetic control component controls the active magnet to repeatedly change the magnetic force and magnetic pole, so that the passive magnet component drives the connecting tube to move back and forth on the side close to the active magnet, constantly changing the tube diameter.

[0023] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0024] Through the coordinated operation of the base frame, main frame, and side frame mechanisms, the base frame drives the entire equipment forward. If obstacles are encountered, the main frame can be rotated to avoid them via a rotating mechanism. When all the plants requiring irrigation are on one side of the road, the user can fold the side frame away from the plants to the main frame, disabling that side and preventing water waste. When the equipment is in a large field, the wheels on both sides travel through the gaps between the plants, while the rotating mechanism continuously drives the main and side frame mechanisms to rotate, providing comprehensive, all-around irrigation of the circular area centered on the equipment. This results in high irrigation efficiency and fewer limitations imposed by the terrain. It solves the technical problems of low efficiency in manual spraying and difficulties in obstacle avoidance and turning in existing spray trucks. It achieves improved irrigation efficiency while offering flexible deployment and saving water and space. Attached Figure Description

Similarly, if the user inserts the pin into the first shaft cylinder 131 and the second shaft cylinder 311 on the rear side of the equipment, making them hinged, the side frame mechanism 300 can fold towards the rear of the main frame mechanism 100. The spray pipe 320 is a horizontally arranged rigid straight pipe. The spray pipe 320 is perpendicular to the side of the movable frame 310 away from the main mechanism. The spray pipe 320 has the same diameter as the water supply pipe 120. When the side frame mechanism 300 is fully extended, the spray pipe 320 can be connected to the water supply pipe 120, allowing liquid to enter the spray pipe 320 from the water supply pipe 120. A spray nozzle 321 is fixed at the bottom of the spray pipe 320. The spray nozzle 321 is a nozzle that communicates with the inside of the spray pipe 320 and is used to spray the spray pipe 320. The internal liquid is sprayed onto the ground; there are multiple spray nozzles 321, which are evenly distributed along the length of the spray pipe 320; the end of the spray pipe 320 away from the movable frame 310 is equipped with a solenoid valve, which is used to control the liquid flow; there are two extension pipes, which are arranged parallel to the spray pipe 320, and one end of the extension pipe is fixedly connected to the movable frame 310; multiple tripods 341 are arranged between the two extension pipes and the spray pipe 320, and the three vertices of the tripods 341 are fixed to the outer surfaces of the two extension pipes and the spray pipe 320 respectively, for the combination of the tripods 341 and the extension pipes to fix and support the spray pipe 320; multiple tripods 341 are evenly distributed along the length of the spray pipe 320; the end of the pull rope 152 away from the pull seat 151 is fixed to the top of a tripod 341 away from the main frame mechanism 100.

[0056] Preferably, there are multiple side frame mechanisms 300 on both sides of the main frame mechanism 100. The multiple side frame mechanisms 300 are connected along their length direction. The spray pipes 320 of each side frame mechanism 300 are internally connected. Each side frame mechanism 300 on the same side is hinged to each other, so that the multiple side frame mechanisms 300 can be folded.

[0057] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0058] This embodiment utilizes the cooperation of the base frame mechanism 200, the main frame mechanism 100, and the side frame mechanism 300. During the movement of the equipment by the base frame mechanism 200, if obstacles are encountered, the main frame mechanism 100 can be rotated by the rotating mechanism 600 to avoid them. When all the plants requiring irrigation are on one side of the road, the user can fold the side frame mechanism 300 away from the plants to be close to the main frame mechanism 100, thus disabling that side frame mechanism 300 and preventing water waste. When the equipment is in a large field, the wheels 220 on both sides of the equipment travel through the gaps between the plants, while the rotating mechanism 600 continuously rotates the main frame mechanism 100 and the side frame mechanism 300 as the equipment moves, providing comprehensive, all-around irrigation of the circular area centered on the equipment. This results in high irrigation efficiency and fewer limitations imposed by the field conditions. It solves the technical problems of low efficiency in manual spraying and difficulties in obstacle avoidance and turning around in existing spraying vehicles. It achieves the technical effect of improving irrigation efficiency while being flexible, water-saving, and space-saving. Example 2

[0059] Considering that in the above embodiment one, for small-scale farmland with multiple crops planted side by side, the irrigation needs of different crops vary, and the required water volume for sprinkler irrigation differs, when the side frame mechanism 300 is fully extended, the equipment's rotation radius is too large, making it easy to irrigate other crops. The irrigation radius is difficult to control effectively, causing some inconvenience to the user. Therefore, the device needs improvement, such as... Figures 7 to 9 As shown, the specific structure is as follows:

[0060] The bottom of the water supply pipe 120 is fixedly connected to two first bend pipes 121. The two first bend pipes 121 are respectively fixed at both ends of the water supply pipe 120 near the fixed frame 130. The first bend pipes 121 are arc-shaped pipes. Solenoid valves for controlling the liquid flow are fixed at the connection between the two first bend pipes 121 and the water supply pipe 120.

[0061] The bottom of the spray pipe 320 is fixed with a second bend pipe 330. The second bend pipe 330 is located at the end of the spray pipe 320 near the movable frame 310. The second bend pipe 330 is an arc-shaped pipe.

[0062] A connecting pipe 400 is detachably and fixedly connected between the openings of adjacent first bend pipe 121 and second bend pipe 330. The connecting pipe 400 is made of soft material, preferably rubber, and the connecting pipe 400 connects the first bend pipe 121 and the second bend pipe 330.

[0063] Preferably, the elasticity of the connecting pipe 400 is sufficient to overcome the gravity of the liquid and will not be deformed downwards by the gravity of the liquid itself.

[0064] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0065] In this embodiment, the cooperation of the first bend pipe 121, the second bend pipe 330, and the connecting pipe 400 enables the side frame mechanism 300 to continue spraying even after folding. The rotation radius during irrigation is controlled by the folding degree control device of multiple side frame mechanisms 300. When the side frame mechanism 300 is folded relative to the main frame mechanism 100, the solenoid valves at both ends of the water supply pipe 120 are closed, and the solenoid valve at the connection between the water supply pipe 120 and the first bend pipe 121 is open. This allows the liquid to flow from the water supply pipe 120 to the first bend pipe 121, then from the first bend pipe 121 to the connecting pipe 400, and then from the connecting pipe 400 to the second bend pipe 330. Finally, the liquid flows from the second bend pipe 330 into the spray pipe 320.

[0066] This invention solves the technical problem that when the equipment rotates for irrigation in small-scale farmland, the large irrigation radius makes it easy to irrigate other crops. It achieves controllable rotation irrigation radius, multi-stage unfolding and multi-stage folding of the equipment, thereby improving irrigation accuracy. Example 3

[0067] Considering that during the folding process of the side frame mechanism 300 in the above embodiment two, the connecting pipe 400 may bend into a sharp corner, resulting in a decrease in the liquid flow rate in the connecting pipe 400 or damage to the connecting pipe 400, the device needs to be improved, such as... Figure 10 and Figure 11 As shown, the specific structure is as follows:

[0068] The second bend pipe 330 and the first bend pipe 121, which are connected to each other, are detachably fixed with connecting pieces 410 on the same side. An active magnet 420 is fixed between the two connecting pieces 410. Each of the two connecting pieces 410 is fixedly connected to an active magnet 420. The connecting piece 410 is a rectangular plate-shaped magnetic block, preferably a permanent magnet. The connecting piece 410 is a rectangular soft sheet made of elastic rubber. One side of the active magnet 420 faces the connecting pipe 400.

[0069] Multiple passive magnet assemblies 430 are fixed on the outer surface of the connecting tube 400 near the active magnet 420. The multiple passive magnet assemblies 430 are evenly distributed along the length of the connecting tube 400. The passive magnet assembly 430 is preferably a soft magnetic sheet. The soft magnetic sheet and the opposite surface of the active magnet 420 can attract each other.

[0070] The elasticity of the connecting piece 410 is less than that of the connecting tube 400, so that the connecting tube 400 can deform towards the passive magnet assembly 430 under the attraction of the active magnet 420.

[0071] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0072] In this embodiment, the active magnet 420 and the passive magnet assembly 430 attract each other, and the direction of the attractive force on the connecting tube 400 is as follows: Figure 11 In the direction indicated by the hollow arrow, after the connecting tube 400 is bent, the active magnet 420 attracts the passive magnet assembly 430 on the connecting tube 400 towards the active magnet 420; as shown by the hollow arrow. Figure 11 In the direction indicated by the solid arrow, when the liquid flows through the connecting pipe 400, the liquid exerts pressure on the inner wall of the connecting pipe 400 on the side away from the active magnet 420 due to inertia and centrifugal force. Thus, magnetic attraction and pressure are applied to the inner walls on both sides of the connecting pipe 400 in opposite directions, which expands the internal space of the connecting pipe 400, allowing the liquid in the middle of the connecting pipe 400 to flow more smoothly and preventing the connecting pipe 400 from being damaged due to excessive bending. Since the connecting piece 410 is detachably fixed to the side wall of the bent pipe, the user can place the connecting piece 410 and the active magnet 420 on either side of the connecting pipe 400 as needed. Example 4

[0073] Considering that in Embodiment 3, after the connecting pipe 400 is bent, the water source entering the water supply pipe 120 during irrigation may be unstable, or the water source may be suddenly shut off, causing the connecting pipe 400 to undergo rapid deformation instantaneously. This could lead to a risk of the connecting pipe 400 detaching from the fixing point of the first bend connector 121 or the second bend connector 330. Therefore, improvements to the device are needed, such as... Figures 12 to 16 As shown, the specific structure is as follows:

[0074] A paraffin membrane 440 is coaxially disposed inside the connecting tube 400. The paraffin membrane 440 is a tubular elastic membrane fixed to the inner side of the inner wall of the connecting tube 400. A paraffin cavity 441 is formed between the paraffin membrane 440 and the inner wall of the connecting tube 400. The paraffin cavity 441 is a closed cavity. The paraffin cavity 441 is filled with paraffin.

[0075] A temperature control component 700 is fixed on one side of the first bent pipe 121. A heating wire 710 is fixedly extended from the temperature control component 700. The heating end of the heating wire 710 passes through the first bent pipe 121 and enters the paraffin cavity 441 to heat and soften the paraffin. The temperature control component 700 is used to control the temperature of the heating wire 710. This is existing technology and will not be described in detail here.

[0076] The passive magnet assembly 430 includes a passive magnet 432 and a passive membrane 431. The magnetic pole face of the passive magnet 432 faces the active magnet 420. The passive magnet 432 is a permanent magnet. The passive membrane 431 is an elastic soft membrane protruding from the surface of the connecting tube 400. The passive membrane 431, the passive magnet 432, and the outer surface of the connecting tube 400 form a shaping cavity 433. The shaping cavity 433 is a cavity and is connected to the paraffin cavity 441, allowing paraffin to enter the shaping cavity 433.

[0077] Multiple separator membranes 442 are fixed inside the paraffin cavity 441. Each separator membrane 442 is a long strip-shaped elastic soft membrane. The length direction of the separator membrane 442 is parallel to the length direction of the connecting tube 400. One side of the separator membrane 442 is fixedly connected to the paraffin membrane 440, and the other side is connected to the inner wall of the connecting tube 400. The separator membranes 442 are evenly distributed around the circumference of the paraffin membrane 440 to divide the paraffin cavity 441 radially into multiple independent cavities, thereby preventing the paraffin from accumulating at the bottom of the paraffin cavity 441 due to gravity when it softens.

[0078] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0079] In this embodiment, by setting up a paraffin film 440, a passive film 431, and paraffin filling, the heating wire 710 heats the paraffin before the connecting tube 400 is bent, softening the paraffin so that the connecting tube 400 can be bent freely. After bending to the required angle, the heating is stopped, and the water flow causes the paraffin to cool and harden, so that the diameter and bending angle of the connecting tube 400 are fixed, thereby reducing the influence of the liquid flow on the connecting tube 400. At the same time, when the paraffin in the shaping cavity 433 softens, it can attract the passive magnet 432 towards the active magnet 420. After hardening, the overall strength of the connecting tube 400 is further enhanced. Example 5

[0080] Considering that in the above-described embodiment four, when the equipment irrigates crops with liquids such as water and fertilizer, there are some unabsorbed particles or impurities in the liquid, and some impurities or particles are not mixed evenly with the liquid, which may cause a certain degree of accumulation and blockage in the connecting pipe 400, thus affecting the sprinkler irrigation process, it is necessary to improve the device, such as... Figures 17 to 20 As shown, the specific structure is as follows:

[0081] The active magnet 420 is a DC electromagnet. A magnetic control component 800 is fixed on one side of the second bent pipe 330. The magnetic control component 800 is electrically connected to the active magnet 420 and is used to control the magnitude and direction of the current flowing through the active magnet 420, thereby controlling the magnitude of the magnetic force and the direction of the magnetic poles of the active magnet 420.

[0082] Both the temperature control component 700 and the magnetic control component 800 are controlled by a microcontroller through a fixed program. Since the microcontroller is existing technology, it will not be described in detail.

[0083] The two separating membranes 442 adjacent to the shaping cavity 433 are heat insulation membranes 443. These heat insulation membranes 443 are highly heat-insulating elastic membranes. The two heat insulation membranes 443 radially divide the paraffin cavity 441 into left and right parts, each equipped with an independent heating wire 710. The paraffin in the part connected to the shaping cavity 433 is a low-melting-point paraffin, with a melting point lower than that of the paraffin on the side away from the shaping cavity 433. When the connecting pipe 400 is bent, the paraffin is cooled and solidified by the liquid flow. At this time, the heating wire 710 near the shaping cavity 433 is heated individually, causing the paraffin inside the part of the paraffin cavity 441 connected to the shaping cavity 433 to melt. Simultaneously, the magnetic control component 800 controls the active magnet 420 to repeatedly change the magnetic force and magnetic poles, such as... Figure 19 and Figure 20 This causes the passive magnet assembly 430 to drive the connecting pipe 400 to move back and forth near the active magnet 420, constantly changing the pipe diameter.

[0084] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0085] In this embodiment, by setting a heat insulation film 443, the paraffin cavity 441 is divided into two parts, each of which is equipped with a heating wire 710. The two heating wires 710 work separately. The paraffin melting points of the two parts are different. The paraffin is heated and softened before the connecting tube 400 needs to be bent. After the connecting tube 400 is bent and shaped, the part of the paraffin cavity 441 near the passive magnet assembly 430 is heated and softened. At this time, the magnetic control assembly 800 repeatedly changes the magnetic force and magnetic poles, causing the part of the connecting tube 400 near the active magnet 420 to shake back and forth, so that impurity particles in the connecting tube 400 will not accumulate, and at the same time, the absorption of particles by the liquid is accelerated.

[0086] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
