Description

A box-type variable frequency water supply equipment with energy-saving function Technical Field

[0001] The present invention relates to the technical field of water supply equipment, in particular to a box-type variable frequency water supply equipment with energy-saving function. Background Art

[0002] A water supply system refers to a complex system of reservoirs, water pumps, pipelines, and other engineering components that supply water to different water-using departments according to certain quality requirements. In terms of technical performance, the entire water supply system should meet the user's needs for water quality, water volume, and water pressure. Furthermore, during the entire infrastructure construction process and production operations, it should also require low infrastructure investment, low operating costs, and convenient operation and management. The box-type water supply equipment should be able to operate safely and fully realize the economic benefits of the entire water supply system.

[0003] Existing water supply devices usually clean the water tank during maintenance. After a long period of water supply, impurities in the water tank have accumulated into scale, which is difficult to clean. In addition, the scale accumulates on the inner wall and easily corrodes the inner wall, causing damage to the water tank.

[0004] Summary of the Invention

[0005] The purpose of the present invention is to provide a box-type variable frequency water supply equipment with energy-saving function to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A box-type variable frequency water supply device with an energy-saving function comprises: a water tank, a water inlet and a water outlet are provided on the side wall of the water tank, a pump assembly is provided at the end of the water outlet away from the water tank, a cleaning device is provided in the water tank, a water pump is provided in the pump assembly, and the water pump is connected to the water outlet through a pipeline, and the cleaning device comprises: a rotating shaft, the rotating shaft is provided in the water tank, and the rotating shaft is rotatably connected to the inner wall of the water tank;

[0008] The staff controls the water inlet to open through the controller, and then the water is transported to the water tank for storage through the water inlet. When the water consumption increases, the controller controls the pump unit to start and the water outlet to open. The water pump in the pump unit draws water from the water tank, and the water in the water tank is then transported to the water pump in the pump unit through the water outlet. The water pump draws water into the pipe system, thereby realizing pipeline water supply. In the process of transporting the water in the water tank to the water outlet, the controller controls the cleaning device to start, and the cleaning device then rotates under the action of water flow. During the rotation of the cleaning device, the inner wall of the water tank is cleaned. The cleaning device cleans impurities attached to the inner wall of the water tank to prevent impurities from accumulating on the inner wall to form scale, thereby extending the water tank maintenance cycle and saving the water tank maintenance cost. Secondly, the water tank is cleaned by the cleaning device, which improves the water quality in the water tank.

[0009] Preferably, a plurality of fixing rings are provided on the rotating shaft, and a plurality of support arms are provided on the side of the fixing ring away from the rotating shaft. The support arms are arranged around the axis of the fixing ring, and a plurality of impeller blades are provided between two adjacent support arms, and the impeller blades form an angle with the support arms.

[0010] Preferably, an electromagnetic coil is provided inside the water tank away from the fixing ring of the support arm, the support arm is a magnetic conductor, a cleaning groove is provided on the side of the support arm close to the water outlet, a cleaning rod is provided in the cleaning groove, and the cleaning rod is rotatably connected to the cleaning groove through a rotating shaft.

[0011] Preferably, a power chamber is provided inside the cleaning groove, and a rotating shaft in the cleaning rod is provided with a rotating gear through the power chamber, and the rotating gear is an incomplete gear. A sliding groove is provided on the side of the support arm away from the cleaning groove, and a slider is slidably connected in the sliding groove. A pull rope is provided in the sliding groove, one end of the pull rope is connected to the slider, and the other end of the pull rope is connected to the rotating shaft on the cleaning rod, and a torsion spring is provided on the rotating shaft on the cleaning rod.

[0012] Preferably, two movable grooves are provided on the shaft arm of the rotating shaft, one of the movable grooves is provided on the side of the rotating shaft close to the water inlet, and the other movable groove is provided on the side of the rotating shaft close to the water outlet, the fixed ring is slidingly connected to the movable groove, an electromagnetic spring is provided in the movable groove, one end of the electromagnetic spring is connected to the fixed ring, and the other end of the electromagnetic spring is connected to the side wall of the movable groove.

[0013] Preferably, the impeller blades on the plurality of fixed rings are arranged crosswise, the impeller blades are combined into a complete impeller, and a filter screen is provided in the water outlet;

[0014] When the controller controls the pump assembly to start, the water in the water tank is immediately transported to the pipeline under the action of the water pump. The water in the water tank moves from one side of the water inlet to the water outlet. During the water transportation process, the water flow impacts the impeller blades, and the impeller blades immediately generate rotational force under the action of the water flow, and the impeller blades immediately rotate. During the rotation of the impeller blades, the impeller blades drive the support arm to rotate, and the rotation of the support arm drives the fixed ring to rotate. When the fixed ring rotates, the fixed ring drives the rotating shaft to rotate;

[0015] Since the support arm is a magnetic conductor, during its rotation, the support arm continuously cuts the magnetic flux lines in the electromagnetic coil set inside the water tank, thereby causing the electromagnetic coil to generate magnetic force, and then magnetism generates electricity. The electricity generated by the electromagnetic coil is transmitted to the battery for storage through the circuit, thereby realizing resource utilization and achieving energy saving effect.

[0016] When the support arm rotates, the slider moves under the action of centrifugal force, and the slider moves along the sliding groove to the side away from the fixed ring. Because the electromagnetic coil generates magnetic force during the rotation of the support arm, the magnetic force also attracts the slider to move to the side close to the inner wall of the water tank. During the movement of the slider, the slider drives the pull rope to move, and the pull rope is pulled. In the process of being slid and pulled, the pull rope at the other end pulls the rotating shaft on the cleaning rod to rotate. During the rotation of the rotating shaft, the rotating shaft drives the cleaning rod to rotate, and the cleaning rod moves to the side away from the cleaning groove, and contacts the inner wall of the water tank after rotating. When the impeller blades rotate, the supporting arm is driven to rotate, and the rotation of the supporting arm drives the cleaning rod to rotate. During the rotation of the cleaning rod, the inner wall of the water tank is cleaned, and impurities attached to the inner wall of the water tank are cleaned off, preventing impurities from adhering to the inner wall of the water tank to form scale. Impurities in the water tank are not easily attached to the inner wall of the water tank under the stirring action of the support arm and the impeller blades, thereby extending the maintenance cycle of the water tank, saving the maintenance cost of the water tank, and improving the water quality in the water tank.

[0017] The rotation drives the rotating gear in the power chamber to rotate. Since the rotating gear is an incomplete gear, when the slider moves to the end of the sliding groove, the rotating gear is freed from the restraint of the teeth, and then the rotating gear is reset under the action of the torsion spring. During the reset process, the rotating gear drives the rotating shaft to reset, and the rotating shaft drives the cleaning rod to reset. The cleaning rod rotates to one side of the cleaning groove, thereby realizing multiple intermittent cleaning of the inner wall of the water tank, improving the cleaning efficiency and thus improving the cleaning quality;

[0018] When the water supply needs to be stopped, the controller controls the pump unit to shut down. The controller controls the electromagnetic spring in the movable groove to be energized, and the electromagnetic spring is energized to contract. During the contraction process, the electromagnetic spring drives the fixed ring to move, and the fixed rings on both sides move along the movable groove to the side away from the water inlet and the water outlet respectively. Then the controller controls the pump unit to shut down. At this time, the staggered impeller blades are combined into an impeller as a whole. After the valve is closed, water forms a water hammer, which impacts the impeller blades. The staggered impeller blades disperse the impact of the water hammer, thereby reducing the impact of the water hammer on the pump unit and protecting the pump unit.

[0019] The cleaned impurities are transported to the water outlet under the action of water flow. During the transportation process, the impurities encounter the filter screen set in the water outlet and are then filtered by the filter screen.

[0020] The water flow is used to drive the support arm to rotate. During the rotation of the support arm, the cleaning rod is driven to clean the inner wall of the water tank. At the same time, during the rotation of the support arm, the support arm cuts the magnetic lines of force, causing the electromagnetic coil to generate electricity, thereby improving resource utilization and achieving energy-saving effects.

[0021] Preferably, a battery is provided between the water tank and the pump assembly, and the angle between the impeller blade and the support arm is 30°-45°.

[0022] Preferably, the pump assembly is provided with a heat-to-electricity device, the pump assembly is further provided with a vibration generator, the heat-to-electricity device is electrically connected to a battery, the battery is electrically connected to the vibration generator, and the pump assembly is provided with a vibration frequency sensor;

[0023] During the rotation of the cleaning device, the magnetic flux lines are cut in the electromagnetic coil, causing the electromagnetic coil to generate magnetic force, thereby generating electricity. The electricity is then transmitted to the battery through the circuit for storage. The pump unit is started under the control of the controller, and the water pump in the pump unit generates heat during operation. The heat accumulates in the pump unit, and the heat-to-electric device is immediately started under the control of the controller. The heat-to-electric device immediately converts the heat in the pump unit into electrical energy, which is also transmitted to the battery through the circuit for storage. After the heat-to-electric device converts the heat in the pump unit, the heat dissipation efficiency in the pump unit is improved, and the utilization rate of heat energy is improved, thereby achieving heat dissipation in the pump unit and utilizing heat energy.

[0024] Since the water pump generates noise during operation, the vibration frequency sensor converts the vibration frequency signal generated by the noise into an electrical signal and transmits it to the controller, which then analyzes it. The controller then controls the vibration generator in the pump unit to start, and the battery then transmits the stored electrical energy to the vibration generator through the circuit. The controller controls the vibration generator to generate a relative vibration frequency based on the vibration frequency received by the vibration frequency sensor, so that the vibration frequency of the noise and the vibration frequency generated by the vibration generator cancel each other out, thereby achieving noise attenuation, thereby achieving the purpose of noise reduction and improving the noise reduction effect of the pump unit.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. Use water flow to drive the support arm to rotate. During the rotation of the support arm, the cleaning rod is driven to clean the inner wall of the water tank. At the same time, during the rotation of the support arm, the support arm cuts the magnetic flux lines, causing the electromagnetic coil to generate electricity, thereby improving resource utilization and achieving energy-saving effects.

[0027] 2. After the heat-to-electricity device converts the heat in the pump unit, it improves the heat dissipation efficiency in the pump unit and the utilization rate of thermal energy, which not only realizes the heat dissipation in the pump unit, but also makes use of the thermal energy. Since the water pump generates noise during operation, the vibration frequency sensor converts the vibration frequency signal generated by the noise into an electrical signal and transmits it to the controller, which then analyzes it. The controller then controls the vibration generator in the pump unit to start, and the battery then transmits the stored electrical energy to the vibration generator through the circuit. The controller controls the vibration generator to generate a relative vibration frequency according to the vibration frequency received by the vibration frequency sensor, so that the vibration frequency of the noise and the vibration frequency generated by the vibration generator cancel each other out, thereby achieving noise attenuation, thereby achieving the purpose of noise reduction and improving the noise reduction effect of the pump unit.

[0039] Please refer to Figures 1 to 7, the present invention provides a technical solution:

When the water consumption increases, the controller controls the pump unit 2 to start and the water outlet 12 to open, and the water pump in the pump unit 2 draws water from the water tank 1. The water in the water tank 1 is then transported to the water pump in the pump unit 2 through the water outlet 12. The water pump draws water into the pipe system, thereby realizing pipeline water supply. During the process of transporting the water in the water tank 1 to the water outlet 12, the controller controls the cleaning device 3 to start, and the cleaning device 3 then rotates under the action of the water flow. During the rotation of the cleaning device 3, the inner wall of the water tank 1 is cleaned, and the cleaning device 3 cleans off the impurities attached to the inner wall of the water tank 1 to prevent impurities from accumulating on the inner wall to form scale.

[0042] As a specific embodiment of the present invention, a plurality of fixing rings 32 are provided on the rotating shaft 31, and a plurality of support arms 33 are provided on the side of the fixing ring 32 away from the rotating shaft 31. The support arms 33 are arranged around the axis of the fixing ring 32, and a plurality of impeller blades 34 are provided between two adjacent support arms 33. The impeller blades 34 form an angle with the support arms 33, and the angle between the impeller blades 34 and the support arms 33 is 30°.

[0043] As a specific embodiment of the present invention, an electromagnetic coil is provided inside the water tank 1 where the support arm 33 is away from the fixing ring 32, and the support arm 33 is a magnetic conductor. A cleaning groove 35 is provided on the side of the support arm 33 close to the water outlet 12, and a cleaning rod 36 is provided in the cleaning groove 35. The cleaning rod 36 is rotatably connected to the cleaning groove 35 through a rotating shaft.

[0044] As a specific embodiment of the present invention, a power chamber 351 is provided inside the cleaning groove 35, and the rotating shaft in the cleaning rod 36 passes through the power chamber 351 and is provided with a rotating gear 352, and the rotating gear 352 is an incomplete gear. A sliding groove 37 is provided on the side of the support arm 33 away from the cleaning groove 35, and a slider 38 is slidably connected in the sliding groove 37. A pull rope is provided in the sliding groove 37, one end of the pull rope is connected to the slider 38, and the other end of the pull rope is connected to the rotating shaft on the cleaning rod 36, and a torsion spring is provided on the rotating shaft on the cleaning rod 36.

[0045] As a specific embodiment of the present invention, two movable grooves 39 are provided on the shaft arm of the rotating shaft 31, one of the movable grooves 39 is provided on the side of the rotating shaft 31 close to the water inlet 11, and the other movable groove 39 is provided on the side of the rotating shaft 31 close to the water outlet 12, the fixed ring 32 is slidingly connected to the movable groove 39, and an electromagnetic spring is provided in the movable groove 39, one end of the electromagnetic spring is connected to the fixed ring 32, and the other end of the electromagnetic spring is connected to the side wall of the movable groove 39.

[0046] As a specific embodiment of the present invention, the impeller blades 34 on the plurality of the fixing rings 32 are arranged crosswise, and the impeller blades 34 are combined into a complete impeller, and a filter screen is provided in the water outlet 12;

[0047] When the controller controls the pump assembly 2 to start, the water in the water tank 1 is immediately transported to the pipeline under the action of the water pump. The water in the water tank 1 moves from one side of the water inlet 11 to the water outlet 12. During the process of transporting the water in the water tank 1, the water flow impacts the impeller blade 34. The impeller blade 34 then generates a rotational force under the action of the water flow, and the impeller blade 34 then rotates. During the rotation of the impeller blade 34, the impeller blade 34 drives the support arm 33 to rotate. The rotation of the support arm 33 drives the fixing ring 32 to rotate. When the fixing ring 32 rotates, the fixing ring 32 drives the rotating shaft 31 to rotate.

[0048] Since the support arm 33 is a magnetic conductor, during the rotation of the support arm 33, the support arm 33 continuously cuts the magnetic flux lines of the electromagnetic coil disposed inside the water tank 1, thereby causing the electromagnetic coil to generate magnetic force, thereby causing magnetism to generate electricity. The electricity generated by the electromagnetic coil is then transmitted to the battery for storage through the circuit.

[0049] During the rotation of the support arm 33, the slider 38 moves under the action of centrifugal force, and the slider 38 moves along the sliding groove 37 to the side away from the fixed ring 32. Since the electromagnetic coil generates magnetic force during the rotation of the support arm 33, the magnetic force also attracts the slider 38 to move to the side close to the inner wall of the water tank 1. During the movement of the slider 38, the slider 38 drives the pull rope to move, and the pull rope is then pulled. In the process of the pull rope being slid and pulled, the other end of the pull rope pulls the rotating shaft on the cleaning rod 36 to rotate. During the rotation of the rotating shaft, the rotating shaft drives the cleaning rod 36 to rotate. The rod 36 rotates, and the cleaning rod 36 moves to the side away from the cleaning groove 35. After the cleaning rod 36 rotates, it contacts the inner wall of the water tank 1. When the impeller blade 34 rotates, it drives the support arm 33 to rotate. The rotation of the support arm 33 drives the cleaning rod 36 to rotate. During the rotation of the cleaning rod 36, the inner wall of the water tank 1 is cleaned, and impurities attached to the inner wall of the water tank 1 are cleaned off to prevent impurities from adhering to the inner wall of the water tank 1 to form scale. Under the stirring action of the support arm 33 and the impeller blade 34, the impurities in the water tank 1 are not easily attached to the inner wall of the water tank 1.

[0050] The rotation drives the rotating gear 352 in the power chamber 351 to rotate. Since the rotating gear 352 is an incomplete gear, when the slider 38 moves to the end of the sliding groove 37, the rotating gear 352 is freed from the restraint of the teeth. Then, the rotating gear 352 is reset under the action of the torsion spring. During the reset process, the rotating gear 352 drives the rotating shaft to reset, and the rotating shaft drives the cleaning rod 36 to reset. The cleaning rod 36 rotates to one side of the cleaning groove 35, thereby realizing multiple intermittent cleaning of the inner wall of the water tank 1.

[0051] When it is necessary to stop the water supply, the controller controls the electromagnetic spring in the movable groove 39 to be energized when the pump unit 2 is controlled to be closed. The electromagnetic spring is energized and contracts. During the contraction process, the electromagnetic spring drives the fixed ring 32 to move. The fixed rings 32 on both sides move along the movable groove 39 to the side away from the water inlet 11 and the water outlet 12 respectively. Then the controller controls the pump unit 2 to be closed. At this time, the staggered impeller blades 34 are combined into an impeller as a whole. After the valve is closed, water forms a water hammer, which impacts the impeller blades 34. The staggered impeller blades 34 disperse the impact of the water hammer, thereby reducing the impact of the water hammer on the pump unit 2 and protecting the pump unit 2.

[0052] The cleaned impurities are transported to the water outlet 12 under the action of the water flow. During the transportation process, the impurities encounter the filter screen provided in the water outlet 12 and are then filtered by the filter screen.

[0053] As a specific embodiment of the present invention, a battery (not shown in the figure) is provided between the water tank 1 and the pump assembly 2 .

[0054] As a specific embodiment of the present invention, the pump assembly 2 is provided with a heat-to-electricity device, the pump assembly 2 is also provided with a vibration generator, the heat-to-electricity device is electrically connected to a battery, the battery is electrically connected to the vibration generator, and the pump assembly 2 is provided with a vibration frequency sensor;

[0055] During the rotation of the cleaning device 3, the magnetic flux lines are cut in the electromagnetic coil, causing the electromagnetic coil to generate magnetic force, thereby generating electricity. The electricity is then transmitted to the battery for storage through the circuit. The pump unit 2 is started under the control of the controller, and the water pump in the pump unit 2 generates heat during operation. The heat accumulates in the pump unit 2. The heat-to-electric device (application number: CN201380055376.6, which discloses a thermoelectric converter) is then started under the control of the controller. The heat-to-electric device then converts the heat in the pump unit 2 into electrical energy, which is also transmitted to the battery for storage through the circuit. After the heat-to-electric device converts the heat in the pump unit 2, it not only achieves heat dissipation in the pump unit 2, but also makes use of the heat energy.

[0056] Since the water pump generates noise during operation, the vibration frequency sensor converts the vibration frequency signal generated by the noise into an electrical signal and transmits it to the controller, which then analyzes it. The controller then controls the vibration generator in the pump group device 2 to start, and the battery then transmits the stored electrical energy to the vibration generator through the circuit. The controller controls the vibration generator to generate a relative vibration frequency based on the vibration frequency received by the vibration frequency sensor, so that the vibration frequency of the noise and the vibration frequency generated by the vibration generator cancel each other out, thereby achieving noise attenuation and achieving the purpose of noise reduction.

[0057] Working principle of the present invention:

[0058] The staff controls the water inlet 11 to open through the controller, and then the water is transported to the water tank 1 through the water inlet 11 for storage. When the water consumption increases, the controller controls the pump unit 2 to start and the water outlet 12 to open. The water pump in the pump unit 2 draws water from the water tank 1. The water in the water tank 1 is then transported to the water pump in the pump unit 2 through the water outlet 12. The water pump draws water into the pipe system, thereby realizing water supply to the pipe.

[0059] When the controller controls the pump assembly 2 to start, the water in the water tank 1 is immediately transported to the pipeline under the action of the water pump. The water in the water tank 1 moves from one side of the water inlet 11 to the water outlet 12. During the process of transporting the water in the water tank 1, the water flow impacts the impeller blade 34. The impeller blade 34 then generates a rotational force under the action of the water flow, and the impeller blade 34 then rotates. During the rotation of the impeller blade 34, the impeller blade 34 drives the support arm 33 to rotate. The rotation of the support arm 33 drives the fixing ring 32 to rotate. When the fixing ring 32 rotates, the fixing ring 32 drives the rotating shaft 31 to rotate.

[0060] Since the support arm 33 is a magnetic conductor, during the rotation of the support arm 33, the support arm 33 continuously cuts the magnetic flux lines of the electromagnetic coil provided inside the water tank 1, thereby causing the electromagnetic coil to generate magnetic force, thereby causing magnetism to generate electricity, and the electricity generated by the electromagnetic coil is transmitted to the battery for storage through the circuit;

[0061] During the rotation of the support arm 33, the slider 38 moves under the action of centrifugal force, and the slider 38 moves along the sliding groove 37 to the side away from the fixed ring 32. Since the electromagnetic coil generates magnetic force during the rotation of the support arm 33, the magnetic force also attracts the slider 38 to move to the side close to the inner wall of the water tank 1. During the movement of the slider 38, the slider 38 drives the pull rope to move, and the pull rope is then pulled. In the process of the pull rope being slid and pulled, the other end of the pull rope pulls the rotating shaft on the cleaning rod 36 to rotate. During the rotation of the rotating shaft, the rotating shaft drives the cleaning rod 36 to rotate. The rod 36 rotates, and the cleaning rod 36 moves to the side away from the cleaning groove 35. After the cleaning rod 36 rotates, it contacts the inner wall of the water tank 1. When the impeller blade 34 rotates, it drives the support arm 33 to rotate. The rotation of the support arm 33 drives the cleaning rod 36 to rotate. During the rotation of the cleaning rod 36, the inner wall of the water tank 1 is cleaned, and impurities attached to the inner wall of the water tank 1 are cleaned off to prevent impurities from adhering to the inner wall of the water tank 1 to form scale. Under the stirring action of the support arm 33 and the impeller blade 34, the impurities in the water tank 1 are not easily attached to the inner wall of the water tank 1.

[0062] The rotation drives the rotating gear 352 in the power chamber 351 to rotate. Since the rotating gear 352 is an incomplete gear, when the slider 38 moves to the end of the sliding groove 37, the rotating gear 352 is freed from the restraint of the teeth. Then, the rotating gear 352 is reset under the action of the torsion spring. During the reset process, the rotating gear 352 drives the rotating shaft to reset, and the rotating shaft drives the cleaning rod 36 to reset. The cleaning rod 36 rotates to one side of the cleaning groove 35, thereby realizing multiple intermittent cleaning of the inner wall of the water tank 1.

[0063] When it is necessary to stop the water supply, the controller controls the electromagnetic spring in the movable groove 39 to be energized when the pump unit 2 is controlled to be closed. The electromagnetic spring is energized and contracts. During the contraction process, the electromagnetic spring drives the fixed ring 32 to move. The fixed rings 32 on both sides move along the movable groove 39 to the side away from the water inlet 11 and the water outlet 12 respectively. Then the controller controls the pump unit 2 to be closed. At this time, the staggered impeller blades 34 are combined into an impeller as a whole. After the valve is closed, water forms a water hammer, which impacts the impeller blades 34. The staggered impeller blades 34 disperse the impact of the water hammer, thereby reducing the impact of the water hammer on the pump unit 2 and protecting the pump unit 2.

[0064] The cleaned impurities are transported to the water outlet 12 under the action of the water flow. During the transportation process, the impurities encounter the filter screen provided in the water outlet 12 and are then filtered by the filter screen.

[0065] During the rotation of the cleaning device 3, the magnetic flux lines are cut in the electromagnetic coil, causing the electromagnetic coil to generate magnetic force, thereby generating electricity. The electricity is then transmitted to the battery through the circuit for storage. The pump unit 2 is started under the control of the controller, and the water pump in the pump unit 2 generates heat during operation. The heat accumulates in the pump unit 2. The heat-to-electric device is then started under the control of the controller, and the heat-to-electric device converts the heat in the pump unit 2 into electrical energy. The electrical energy is also transmitted to the battery through the circuit for storage. After the heat-to-electric device converts the heat in the pump unit 2, it not only achieves heat dissipation in the pump unit 2, but also makes use of the heat energy.

[0066] Since the water pump generates noise during operation, the vibration frequency sensor converts the vibration frequency signal generated by the noise into an electrical signal and transmits it to the controller, which then analyzes it. The controller then controls the vibration generator in the pump group device 2 to start, and the battery then transmits the stored electrical energy to the vibration generator through the circuit. The controller controls the vibration generator to generate a relative vibration frequency based on the vibration frequency received by the vibration frequency sensor, so that the vibration frequency of the noise and the vibration frequency generated by the vibration generator cancel each other out, thereby achieving noise attenuation and achieving the purpose of noise reduction.
