DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-24, the utility model provides a technical solution: a detachable air filter, including a housing 1, a disassembly mechanism 2 is arranged inside the housing 1, an air inlet 3 is arranged at the top of the housing 1, and air outlets 4 are arranged on both side surfaces of the housing 1. The number of the air outlets 4 and the air inlet 3 is several, and the air outlet 4 is located at the bottom of the disassembly mechanism 2.

[0026] The disassembly mechanism 2 includes a filter plate 201, a fixing plate 202 is fixedly arranged at the top of the filter plate 201, a moving plate 203 is arranged on one side of the fixing plate 202, the moving plate 203 is in contact with the filter plate 201, a transverse groove 204 is arranged on the inner wall of the top end of the housing 1, a threaded rod 205 is arranged inside the transverse groove 204, one end of the moving plate 203 is movably arranged in the transverse groove 204, a connecting spring 206 is arranged between the moving plate 203 and the fixing plate 202, one end of the threaded rod 205 is fixedly provided with a first gear 207, a second gear 208 is arranged on the front surface of the first gear 207, and the second gear 208 is in transmission connection with the first gear 207 through a conveyor belt.

[0027] A support plate 209 is arranged at the bottom of the filter plate 201. The number of the support plates 209 is two, and both support plates 209 are in contact with the filter plate 201. A hole groove 5 is arranged on one side surface of the housing 1, and the hole groove 5 is communicated with the transverse groove 204.

[0028] A sealing plate 210 is arranged inside the hole groove 5, and the sealing plate 210 is fixedly connected with the filter plate 201. The sealing plate 210 is adapted to the hole groove 5. The threaded rod 205 penetrates through the sealing plate 210 and is in contact with the sealing plate 210. A rotating rod 211 is arranged on one side of the second gear 208.

[0029] Please refer to Figure 1 and 3 , the rotating rod 211 is in transmission connection with the second gear 208 through threads respectively, and the rotating rod 211 is in contact with the housing 1 and the filter plate 201 respectively. A vertical rod 212 is arranged at one end of the rotating rod 211 away from the second gear 208. An extension rod 213 is fixedly arranged at one end of the vertical rod 212. The extension rod 213 is in contact with the support plate 209, and the extension rod 213 is movably connected with the housing 1.

[0030] During operation, external gas enters the housing 1 through the air inlet 3, and the gas continues to move through the filter plate 201. The gas can be filtered through the filter plate 201 to purify the air. Subsequently, the gas in the housing 1 can be discharged through the air outlet 4 to prevent excessive gas in the housing 1. When the filter plate 201 needs to be disassembled, first rotate the threaded rod 205. Since one end of the threaded rod 205 extends outside the housing 1, it is convenient to rotate. When the threaded rod 205 rotates, the first gear 207 fixedly connected to the threaded rod 205 rotates simultaneously, and the moving plate 203 threadedly connected to the threaded rod 205 moves simultaneously. When the moving plate 203 moves, the distance between the moving plate 203 and the fixed plate 202 can be reduced, and the connecting spring 206 is compressed, which facilitates subsequent operations. When the first gear 207 rotates, since the first gear 207 is drivingly connected to the second gear 208 through a conveyor belt, the second gear 208 rotates simultaneously, and the second gear 208 rotates on one side of the housing 1. During the rotation of the second gear 208, since the rotating rod 211 is drivingly connected to the second gear 208 through a thread, and the rotating rod 211 is in contact with the housing 1 and the filter plate 201 respectively, the rotation of the second gear 208 can cause the rotating rod 211 to move, so that the rotating rod 211 gradually separates from the filter plate 201. When the rotating rod 211 is separated from the filter plate 201, since the threaded rod 205 is no longer rotating at this time, the connecting spring 206 is in a compressed state, and the threaded rod 205 does not rotate, so that the moving plate 203 stops moving. The fixed plate 202 can be moved to the left through the connecting spring 206, and the filter plate 201 rotates simultaneously, and the sealing plate 210 rotates simultaneously, so that the filter plate 201 is exposed, which facilitates the removal and disassembly of the filter plate 201. When the rotating rod 211 moves, the vertical rod 212 and the extension rod 213 move simultaneously. Since the extension rod 213 is movably connected to the housing 1, the movement of the extension rod 213 is ensured.
