[0033] Specifically, when more dust accumulates on the filter screen of the air conditioner indoor unit, the motor 3 is started at this time, and when the motor 3 is started, the driving bevel gear 5 is rotated, and since the driven bevel gear 7 and the driving bevel gear 5 are meshed with each other, the driven bevel gear 7 will also drive the threaded rod 6 to rotate, and since the movable rod 10 is limited by the limit groove 14, the movement of the sliding ring 8 will drive the pivot 9 to displace, and the movement of the pivot 9 will also cause the movable rod 10 to move correspondingly. In the process of moving, the movable rod 10 will push the first gear 11 on the outside to rotate, and since there is a meshing relationship between the first gear 11 and the rack 12, the first gear 11 will drive the movable rod 10 to rotate. Therefore, the movable rod 10 will also rotate while moving, and this combined motion enables the cleaning brush 13 to effectively rotate and clean the filter screen of the air conditioner indoor unit. Through such cleaning, it can be ensured that dust will not accumulate on the filter screen of the air conditioner indoor unit, thereby avoiding the problem of reduced ventilation caused by dust accumulation and reducing the workload of the staff, which can meet the needs of the users.

[0034] Reference Figure 1 , Figure 4 and Figure 5, the dismounting mechanism 2 comprises a hollow block 201 fixedly connected to the top front side of the left wall of the support frame 1, the inner top front and back sides of the hollow block 201 are fixedly connected with springs 202, the bottom ends of the two springs 202 are fixedly connected with a same gear clamping piece 203, the spring 202 can push the gear clamping piece 203 to make it mesh with the second gear 206, the top end middle part of the gear clamping piece 203 is fixedly connected with a connecting column 204, the inner left end middle part of the hollow block 201 is rotatably connected with a rotating rod 205, the outer wall left side of the rotating rod 205 is fixedly connected with the second gear 206, the second gear 206 is meshed and connected with the gear clamping piece 203, when the second gear 206 is meshed with the gear clamping piece 203, the second gear 206 will be limited by the gear clamping piece 203 and cannot rotate, the right end of the second gear 206 penetrates through the hollow block 201 and the support frame 1 and is fixedly connected with a fixed frame 207, the inner bottom front side of the support frame 1 is provided with a mounting groove 208, the inner part of the mounting groove 208 is provided with an air conditioner filter screen 209, the air conditioner filter screen 209 can filter air, the top end of the connecting column 204 penetrates through the hollow block 201 and is rotatably connected with a pull ring 15, the pull ring 15 facilitates the staff to pull the connecting column 204, the inner side size of the mounting groove 208 matches the size of the air conditioner filter screen 209, so that the air conditioner filter screen 209 will not shake;

[0035] Specifically, when the device is used, the filter screen needs to be disassembled, the pull ring 15 is pulled first, when the pull ring 15 is pulled, the connecting column 204 is moved, the connecting column 204 further drives the gear clamping piece 203 to move when moving, the gear clamping piece 203 is out of engagement with the second gear 206 when moving, once the engagement state of the gear clamping piece 203 and the second gear 206 is released, the second gear 206 is no longer limited by the gear clamping piece 203 and can rotate with the rotating rod 205, at this time, the fixed frame 207 is pulled, the air conditioner filter screen 209 can be easily disassembled, which facilitates replacement work, and after the air conditioner filter screen 209 is installed, the spring 202 automatically pushes the gear clamping piece 203 to re-engage with the second gear 206, after the gear clamping piece 203 and the second gear 206 are engaged, the second gear 206 and the rotating rod 205 are limited and cannot rotate, this design ensures that the air conditioner filter screen 209 can be fixed very firmly by the device, thereby ensuring the stable operation of the air conditioner system and the correct installation of the filter screen, and improving the practicality of the device.

[0036] Referring to Figure 1 , the front wall upper and lower sides of the two mounting plates 18 are threadedly connected with screws 19, the rear ends of the plurality of screws 19 penetrate through the corresponding mounting plates 18, the left and right ends of the rear side of the support frame 1 are fixedly connected with mounting racks 17, the rear sides of the two mounting racks 17 are fixedly connected with the mounting plates 18, the mounting plates 18 can be fixed by the screws 19, and then the device is fixed firmly;

[0037] Specifically, by using the screw 19, the mounting plate 18 can be fixed inside the air conditioner, and when the mounting plate 18 is fixed, the mounting frame 17 drives the device to be fixed.

[0038] With reference to Figure 1 , Figure 2 and Figure 4 , the inside left and right sides of the fixed frame 207 are fixedly connected with support rods 16, which are used to prevent the air conditioner filter screen 209 from deforming. The size of the air conditioner filter screen 209 matches the size of the cleaning brush 13. The top left side of the support frame 1 is fixedly connected with a controller 20, which is electrically connected with the motor 3. The controller 20 can be used to control the operation of the motor 3.

[0039] Specifically, the support rods 16 can prevent the air conditioner filter screen 209 from deforming. The size of the air conditioner filter screen 209 matches the size of the cleaning brush 13, so that the air conditioner filter screen 209 will not vibrate. The controller 20 can control the operation of the motor 3. The model of the motor 3 is F130 micro.

[0040] Working principle: when there is a lot of dust accumulated on the air conditioner filter screen, the motor 3 is started at this time. The motor 3 starts to drive the driving bevel gear 5 to rotate. Since the driven bevel gear 7 is engaged with the driving bevel gear 5, the driven bevel gear 7 drives the threaded rod 6 to rotate. Since the movable rod 10 is limited by the limiting groove 14, when the threaded rod 6 rotates, the sliding ring 8 drives the rotating shaft 9 to move. When the rotating shaft 9 moves, it drives the movable rod 10 to move. When the movable rod 10 moves, it drives the first gear 11 on the outside to move. Since the first gear 11 is engaged with the rack 12, the first gear 11 drives the movable rod 10 to rotate. At this time, the movable rod 10 rotates while moving, which can drive the cleaning brush 13 to rotate and clean the air conditioner filter screen, so that dust will not accumulate on the air conditioner filter screen, causing the ventilation volume to decrease.

[0041] When the device is used, the filter screen needs to be disassembled. At this time, the pull ring 15 is pulled. The pull ring 15 is pulled to drive the connecting column 204 to move. When the connecting column 204 moves, it drives the gear card 203 to move. When the gear card 203 moves, it is disengaged from the engagement state with the second gear 206. The second gear 206 is not limited by the gear card 203, so it can rotate with the rotating rod 205. At this time, the fixed frame 207 is pulled, so that the air conditioner filter screen 209 can be disassembled and replaced conveniently. When in use, the spring 202 pushes the gear card 203 to engage with the second gear 206. The second gear 206 and the rotating rod 205 are limited and cannot rotate, so that the air conditioner filter screen 209 can be fixed firmly by the device.

[0042] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
