[0001] The invention relates to the technical field of fans, and in particular to an energy-saving fan with convenient replacement of filter plates. Background Art

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and air intake of boilers and industrial furnaces, cooling and ventilation in air conditioning equipment and household appliances, drying and selection of grains, wind tunnel wind sources and inflation and propulsion of hovercraft, etc.

[0003] In the prior art, a filter plate is basically provided inside the air inlet of the fan to filter dust and impurities in the air. As dust accumulates, the filtering effect will be affected, so the filter plate needs to be replaced or cleaned regularly. However, common filter plates are generally installed directly at the air inlet of the fan by screws, which is troublesome to disassemble and assemble, and inconvenient to operate. Therefore, an energy-saving fan with easy replacement of the filter plate is needed to solve the above problem. Summary of the invention

[0004] The object of the present invention is to provide an energy-saving fan with convenient replacement of filter plates, so as to solve the problems raised in the above-mentioned background technology.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] A clamping mechanism, the clamping mechanism comprising six clamps and a cylindrical barrel, the six clamps and the six cylindrical barrels being distributed in a circumferential array around the air inlet pipe;

[0008] The support assembly comprises a support tube, one end of which is plugged into the socket.

[0009] Furthermore, six deep holes are evenly formed at one end of the air inlet pipe away from the fan, a mounting plate is fixedly mounted at one end of the air inlet pipe away from the fan, and six square grooves are evenly formed at one end of the mounting plate away from the air inlet pipe.

[0010] Furthermore, six groups of square grooves are evenly arranged at one end of the air inlet pipe away from the fan, and the six deep holes and the six square grooves are staggered. Circular holes are arranged on the two side walls of the square grooves, and baffle rods are slidably installed inside the circular holes. A spring is fixedly installed between the baffle rods and the bottom inner wall of the circular hole, and an inclined surface is arranged on the adjacent end of each pair of baffle rods.

[0011] Furthermore, one end of the chuck is fixedly connected to a rotating shaft, which is rotatably installed between the two side walls of the square groove. The end of the chuck close to the rotating shaft is fixedly connected to a guide block, an opening is provided inside the guide block, and guide grooves are provided on the inner walls on both sides of the opening.

[0012] Furthermore, the cylindrical tube is slidably installed on the mounting seat, and the mounting seat is fixedly installed on the end of the air inlet pipe away from the fan. Circular openings are opened at both ends of the cylindrical tube, and a connecting column is symmetrically fixedly connected to the middle of the cylindrical tube. The connecting column is slidably arranged inside the guide groove. A cylindrical cavity is opened inside the cylindrical tube, and the cylindrical cavity is connected with the outside world through the circular openings at both ends. A movable rod is slidably installed inside the two circular openings, and a circular plate is fixedly connected to the middle of the movable rod. A spring 2 is fixedly installed between the circular plate and the inner wall on the side close to the mounting seat.

[0013] Furthermore, a plug is fixedly connected to one end of the movable rod away from the circular plate, a storage groove is provided at one end of the plug close to the circular plate, a movable block is slidably arranged on the movable rod, a spring three is fixedly installed between the movable block and the bottom inner wall of the storage groove, and the spring three is sleeved on the movable rod.

[0014] One end of the support tube away from the air inlet pipe is fixedly connected to a pressure plate, and a filter plate is further provided on the side of the pressure plate away from the support tube. Six guide columns are fixedly connected to the side of the pressure plate close to the support tube, and the guide columns are slidably arranged inside the deep holes. Six springs four are arranged between the pressure plate and the air inlet pipe, and the springs four are respectively sleeved on a guide column.

During removal, the plug is detached from the square hole, the second spring rebounds, and the chuck is in a free state and has no function of clamping the filter plate. The support tube can be taken out and replaced and cleaned, thereby avoiding the situation where the filter screen is blocked due to excessive dust accumulation.

[0018] (2) The present invention provides a wave plate. When the fan is working, the flowing air will blow the wave plate to swing. Since the bristles are in close contact with the filter plate, the bristles will be inserted into the gaps in the filter plate when they swing, pushing out the dust inside the filter plate, thereby extending the service life of the filter plate. The filter plate does not need to be replaced frequently, so there is no need to frequently operate the clamping mechanism and the supporting assembly, thereby extending the service life of the device and increasing the practicality of the device.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The plug 45 is stuck in the square groove 22 by the blocking rod 23 and cannot be reset. A continuous force is applied to the cylindrical tube 4 to fix the chuck 3, which is convenient for the subsequent clamping of the filter plate 56.

[0039] One end of the chuck 3 is fixedly connected to a rotating shaft 31, and the rotating shaft 31 is rotatably installed between the two side walls of the square groove 211. The end of the chuck 3 close to the rotating shaft 31 is fixedly connected to a guide block 32, and an opening 321 is provided inside the guide block 32, and guide grooves 322 are provided on the inner walls on both sides of the opening 321.

[0040] The cylindrical tube 4 is slidably installed on the mounting seat 401, and the mounting seat 401 is fixedly installed on the end of the air inlet pipe 2 away from the fan 1. Circular openings 402 are provided at both ends of the cylindrical tube 4. A connecting column 41 is symmetrically fixedly connected to the middle of the cylindrical tube 4. The connecting column 41 is slidably set inside the guide groove 322. A cylindrical cavity 42 is provided inside the cylindrical tube 4. The cylindrical cavity 42 is connected with the outside through the circular openings 402 at both ends. A movable rod 43 is slidably installed inside the two circular openings 402. A circular plate 431 is fixedly connected to the middle of the movable rod 43. A spring 44 is fixedly installed between the circular plate 431 and the inner wall of one side close to the mounting seat 401.

[0041] A plug 45 is fixedly connected to one end of the movable rod 43 away from the circular plate 431, and a storage groove 451 is provided at one end of the plug 45 close to the circular plate 431. A movable block 46 is slidably provided on the movable rod 43, and a spring three 47 is fixedly installed between the movable block 46 and the bottom inner wall of the storage groove 451, and the spring three 47 is sleeved on the movable rod 43.

[0042] A pressure plate 501 is fixedly connected to one end of the support cylinder 5 away from the air inlet pipe 2, a filter plate is arranged on the side of the pressure plate 501 away from the support cylinder 5, six guide posts 51 are fixedly connected to the side of the pressure plate 501 close to the support cylinder 5, the guide posts 51 are respectively slidably arranged inside the deep holes 202, six springs 52 are arranged between the pressure plate 501 and the air inlet pipe 2, and the springs 52 are respectively sleeved on one guide post 51;

[0043] By setting the spring four 52, the rebound of the spring four 52 will push the pressure plate 501 and the filter plate to move in the opposite direction until the end of the clamp 3 fits with the filter plate, so as to facilitate clamping the filter plate.

[0044] A plurality of groups of circular holes 53 are provided on one side of the support cylinder 5 close to the pressure plate 501. A cylindrical rod 54 is rotatably installed inside each group of circular holes 53. A corrugated plate 55 is fixedly connected to the side of the cylindrical rod 54 away from the pressure plate 501. A plurality of bristles 56 are fixedly connected to the side of the cylindrical rod 54 close to the pressure plate 501. The bristles 56 are in close contact with the filter plate.

[0045] The wave plate 55 is blown by wind to swing, driving the bristles 56 to swing. The bristles 56 are in close contact with the filter plate and inserted into the gaps of the filter plate during swinging, so as to push out the dust inside the filter plate.

[0046] When in use, the filter plate is placed on the pressure plate 501, and the filter plate is pressed downward, the support tube 5 will be pressed into the air inlet pipe 2, the spring 52 will be compressed, and when the pressure plate 501 contacts the movable rod 43, it will push the movable rod 43 to move synchronously;

[0047] During this process, first, the cylindrical barrel 4 will move synchronously with the movable rod 43, and the clamp 3 will slide inside the guide groove 322 to push the clamp 3 to rotate. Then, when the clamp 3 completes the closing action, the movable rod 43 continues to move, the spring second 44 is compressed, and the plug 45 enters the square groove 22. First, the inclined surface of the plug 45 will squeeze the inclined surface of the blocking rod 23, and the blocking rod 23 slides toward the inside of the circular hole 221, and the spring first 24 is compressed. When the plug 45 moves over the blocking rod 23, the filter plate is stopped from being pressed. Then, the spring first 24, the spring second 44 and the spring fourth 52 all rebound, but the plug 45 is stuck in the square groove 22 and cannot be reset. Therefore, the spring second 44 applies a continuous force to the cylindrical barrel 4, thereby fixing the clamp 3, and the spring fourth 52 continues to rebound to push the pressure plate 501 and the filter plate to move in the opposite direction until the end of the clamp 3 fits the filter plate to clamp the filter plate.

[0048] When the filter needs to be removed, the filter plate is pressed again and the above movement is repeated. When the pressure plate 501 contacts the movable rod 43 again, the pressure is continued until the movable block 46 also enters the inside of the square groove 22. Then the filter plate is released, and the stopper 23 pushes the movable block 46 toward the plug 45. The spring three 47 is compressed until the movable block 46 moves to the inside of the storage groove 451 and cannot move further. The stopper 23 moves along the inclined surface of the movable block 46 and passes over the plug 45. At this time, the spring two 44 rebounds, and the chuck 3 is in a free state and does not have the function of clamping the filter plate. The support tube 5 can be taken out for replacement and cleaning.

[0049] Through the setting of the wave plate 55, when the fan is working, the flowing air will blow the wave plate 55 to swing. Since the bristles 56 are in close contact with the filter plate, the bristles 56 will be inserted into the gaps in the filter plate when swinging, and the dust inside the filter plate will be pushed out, thereby extending the service life of the filter plate. There is no need to frequently replace the filter plate, which extends the service life of the device and increases the practicality of the device.
