[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A stabilizing mechanism 3 and a dustproof mechanism 4 are provided on the driving mechanism 2. A filtering mechanism 6 is provided on the dustproof mechanism 4. A disassembly mechanism 5 is provided on the cover plate 1 and the filtering mechanism 6.

[0033] The cover plate 1 supports and protects the internal components of the central air conditioner. The cover plate 1 is installed at the air inlet of the air conditioner. The driving mechanism 2 can enable the stabilizing mechanism 3 to increase the stability of the installation of the cover plate 1. The device has two cleaning methods: the first is that when the air conditioner is not working, the filtering mechanism 6 can replace the filter and clean the used filter, and collect cleaned dust and other impurities to avoid frequent disassembly and replacement and reduce maintenance costs; the second is that when the filtering mechanism 6 needs to be replaced and thoroughly cleaned after long-term use, the stabilizing mechanism 3 is first driven by the driving mechanism 2 to release the limit, which is convenient for the disassembly of the cover plate 1, and the dustproof mechanism 4 is driven to cover the ventilation holes of the cover plate 1 to prevent the dust shaken off during replacement from polluting the use environment. After the cover plate 1 is removed, the limit on the filtering mechanism 6 is released by the disassembly and assembly mechanism 5, which is convenient for the disassembly of the filtering mechanism 6 for thorough cleaning.

[0034] Reference Figure 2 and Figure 4 The driving mechanism 2 includes a main handle 21 and a control component 22. The main handle 21 is fixedly connected to the bottom wall of the cover plate 1 symmetrically. The control component 22 includes an adjusting handle 221. The bottom walls of the cover plate 1 and the main handle 21 are connected to the adjusting handle 221 by sliding up and down. The adjusting handle 221 and the corresponding main handle 21 are connected by a spring (not shown in the figure); the two adjusting handles 221 are each installed with a U-shaped rod 222 that is slidably connected to the inside of the cover plate 1 on the side away from each other, and the outer walls of the two main handles 21 that are close to each other are both engaged with a limit key 224, and a limit hole 223 corresponding to the limit key 224 is opened in the middle of the adjusting handle 221.

[0035] Reference Figures 2 to 4 The stabilizing mechanism 3 includes an adjusting member 31. The top wall of the U-shaped rod 222 is symmetrically fixedly connected with the adjusting member 31 in the front and rear directions. The adjusting member 31 is composed of a round rod connected to the U-shaped rod 222 and a wedge-shaped block fixedly connected to the top wall of the round rod. The bottom wall of the wedge-shaped block of the adjusting member 31 is formed in an arrow shape by two opposite inclined surfaces. The four corners of the top wall of the cover plate 1 are fixedly connected with a fixing sleeve 32. The inside of the fixing sleeve 32 is symmetrically slidably connected with a stabilizing member 33. The side of the two stabilizing members 33 that are close to each other is fixedly connected with an adjusting wedge block 34. The side walls of the two adjusting wedge blocks 34 that are close to each other are inclined to match the wedge block of the adjusting member 31. The adjusting member 31 is slidably connected to the inside of the corresponding fixing sleeve 32 up and down.

[0036] Reference Figure 3 and Figure 5The dustproof mechanism 4 includes a dustproof component 41 and a driving component 42. The dustproof component 41 includes a Japanese-shaped frame 411. The Japanese-shaped frame 411 is fixedly connected to the middle of the top wall of the cover plate 1. The inside of the Japanese-shaped frame 411 is divided into a driving bin and an adjustment bin from left to right. The adjustment bin of the Japanese-shaped frame 411 is arranged above the ventilation hole of the cover plate 1; a plurality of evenly arranged rotating shafts 412 are rotatably connected between the front and rear inner walls of the adjustment bin of the Japanese-shaped frame 411, and the middle outer walls of the rotating shafts 412 are fixedly connected with dustproof leaf pieces 413, and the upper and lower side walls of the plurality of dustproof leaf pieces 413 are fixedly penetrated with two front-to-back symmetrical traction surrounding ropes 414.

[0037] Reference Figures 3 to 5 The front and rear inner walls of the driving bin of the Japanese-shaped frame 411 are both rotatably connected with a gear 422, and a driving rod 423 is fixedly connected between the two gears 422. The left side walls of the two gears 422 are meshed with a rack 421 that is slidably connected to the inside of the cover plate 1, and the bottom wall of the rack 421 is fixedly connected to the top wall of the adjustment handle 221. The traction rope 414 is fixedly connected to the bottom wall of the driving rod 423 through a fixing nail 424.

[0038] When the filter mechanism 6 needs to be replaced and thoroughly cleaned after being used for a long time, the operator stands under the cover plate 1, holds the corresponding main handle 21 and adjustment handle 221 with both hands, and holds the adjustment handle 221 tightly to slide close to the main handle 21, the spring is compressed, and the adjustment handle 221 drives the U-shaped rod 222 to slide upward to push the adjustment member 31 to move upward, and the adjustment member 31 moves from a state of being tightly attached to the adjustment wedge block 34 to being separated from the adjustment wedge block 34. After the two adjustment wedge blocks 34 are no longer blocked by the adjustment member 31, they move toward the middle of the fixing sleeve 32, and the stabilizing member 33 is retracted into the interior of the fixing sleeve 32, so that the stabilizing member 33 is no longer in contact with the installation position at the air inlet of the central air conditioner. At this time, the cover plate 1 can be pulled out downward to realize the disassembly of the cover plate 1; when the two stabilizing members 33 are far away from each other, the stabilizing member 33 and the four corners of the installation position at the air inlet of the air conditioner form a triangular stable structure, which is convenient for maintaining the stability of the filter mechanism 6 during use.

[0039] During the upward movement of the adjustment handle 221, the rack 421 is driven to slide upward, and the gear 422 then drives the driving rod 423 to rotate clockwise in the driving bin of the sun-shaped frame 411, and the traction loop rope 414 is transmitted accordingly, pulling multiple dust-blocking leaves 413 and the rotating shaft 412 to rotate clockwise. The rotating shaft 412 rotates on the inner wall of the adjustment bin of the sun-shaped frame 411, and the dust-blocking leaves 413 are deflected in the adjustment bin of the sun-shaped frame 411. The angle changes from a vertical state to an inclined state close to a horizontal state, so that the upper part of the ventilation hole of the cover plate 1 changes from an open state to a closed state, so as to prevent the dust shaken off when replacing the filter mechanism 6 from polluting the use environment.

[0040] The operator presses the limit key 224 with his thumb, and presses the limit key 224 through the main handle 21 into the limit hole 223 of the corresponding adjustment handle 221 to lock the position of the adjustment handle 221. At the same time, the contraction state of the stabilizing member 33 and the tilt state of the dust shield leaf 413 are locked, so that the ventilation holes of the cover plate 1 remain in a closed state, preventing the subsequent disassembly and assembly of the filter mechanism 6 from shaking off dust and polluting the environment.

[0041] Reference Figure 1 and Figure 6 The disassembly and assembly mechanism 5 includes a Chinese-character frame 51, the top wall of the cover plate 1 is slidably connected to the Chinese-character frame 51 arranged outside the Japanese-character frame 411, the left part of the top wall of the cover plate 1 is fixedly connected to a fixing plate 52 connected to the left side wall of the Chinese-character frame 51 through a spring, the front and rear inner walls of the Chinese-character frame 51 are symmetrically fixedly connected to racks 2 53, the side walls of the racks 2 53 are meshed with gears 2 54 rotatably connected to the top wall of the cover plate 1, and the top wall of the gears 2 54 is fixedly connected to fan-shaped limit baffles 55.

[0042] Reference Figure 1 , Figure 3 , Figure 6 and Figure 7 The filtering mechanism 6 includes a box body 61 and a roller assembly 62. Two boxes 61 are symmetrically arranged on the top wall of the Japanese-shaped frame 411. The interior of the box body 61 is separated by a horizontal plate into an upper cleaning bin and a lower dust collecting bin. A flexible filter screen 63 is arranged between the two boxes 61. The outer walls of the two boxes 61 on the adjacent sides are provided with holes for the flexible filter screen 63 to pass through. A cleaning component 1 64 and a cleaning component 2 65 are arranged on the box body 61.

[0043] Reference Figures 7 to 9 The roller assembly 62 includes a guide roller 1 621, a guide roller 2 622 and a winding roller 623. The guide roller 1 621, the guide roller 2 622 and the winding roller 623 are rotatably connected between the front and rear inner walls of the cleaning bin on the box body 61. The rear side wall of the winding roller 623 is fixedly connected to the output shaft of the motor 1 624 installed on the box body 61. The guide roller 1 621, the guide roller 2 622 and the winding roller 623 are distributed in an inverted V shape with a horizontal opening. The guide roller 1 621 and the winding roller 623 are both close to the side wall with a hole for the flexible filter screen 63 to pass through. The left and right ends of the flexible filter screen 63 are respectively engaged with the corresponding winding roller 623, and the side walls of the flexible filter screen 63 are attached to the outer walls of the guide roller 1 621 and the guide roller 2 622.

[0044] Reference Figures 7 to 9The cleaning component 1 64 includes a cleaning brush 641. The flexible filter screen 63 between the guide roller 1 621 and the guide roller 2 622 is symmetrically provided with the cleaning brush 641 rotatably connected between the front and rear inner walls of the box body 61. The rear side walls of the cleaning brush 641 are fixedly connected with gears 3 642. The two gears 3 642 are meshed with each other. The rear side wall of one of the gears 3 642 is fixedly connected to the output shaft of the motor 2 643 installed on the box body 61.

[0045] Reference Figures 7 to 9 The cleaning component 2 65 includes a dust collector head 1 651, and the two cleaning brushes 641 are each provided with a dust collector head 1 651 fixedly connected to the front and rear inner walls of the box body 61 on the side away from each other. The flexible filter screen 63 between the guide roller 2 622 and the winding roller 623 is symmetrically provided with a dust collector head 2 652 fixedly connected to the front and rear inner walls of the box body 61. The rear side walls of the dust collector head 1 651 and the dust collector head 2 652 are both connected to a suction pump 654 through a dust collection pipe 653. The suction pump 654 is installed on the rear side wall of the box body 61, and the dust collection pipe 653 is connected to the lower dust collecting bin.

[0046] After the cover plate 1 is removed, it is placed steadily and the return frame 51 is pushed to move toward the fixed plate 52. The return frame 51 slides on the top wall of the cover plate 1, the spring is compressed, and the return frame 51 drives multiple racks 2 53 to move, and at the same time drives multiple gears 2 54 and fan-shaped limit baffles 55 to rotate. Multiple fan-shaped limit baffles 55 are simultaneously rotated from the position overlapping with the top wall of the box body 61 to the position staggered with the top wall of the box body 61. After the fan-shaped limit baffles 55 release the limit on the two box bodies 61, it is convenient and quick to disassemble and replace the filter mechanism 6, thereby improving the maintenance efficiency.

[0047] When the air conditioner is not working, the filtering mechanism 6 can replace the filter and self-clean the used filter; first, after the part of the flexible filter 63 between the two boxes 61 has been filtered for a period of time, one of the motors 624 rotates clockwise to drive the winding roller 623 to wind up the filtered flexible filter 63, and the other motor 1 624 rotates counterclockwise to release the unfiltered flexible filter 63, and the guide roller 2 622 and the guide roller 1 621 play a role in guiding and tensioning.

[0048] After the filtering pollution position of the flexible filter 63 is transmitted to the inside of the cleaning bin on the corresponding box 61, the motor 2 643 rotates to drive the corresponding gear 3 642 to rotate, and the other gear 3 642 rotates in the opposite direction. The two gears 3 642 simultaneously drive the cleaning brush 641 to rotate in the opposite direction to the flexible filter 63, so that the cleaning brush 641 cleans the front and back sides of the filtering pollution position of the flexible filter 63.

[0049] The suction pump 654 is started, and the dust head 651 sucks away the dust, debris and impurities attached to the corresponding cleaning brush 641 to prevent the impurities attached to the surface of the dust head 651 from affecting the cleaning effect of the dust head 651. At the same time, the dust head 652 further vacuums the front and back sides of the position cleaned by the flexible filter 63 to improve the cleaning effect and help keep the air conditioner in good working condition. After passing through the dust suction duct 653, the impurities enter the lower dust collecting bin of the box body 61 for unified collection. The front side wall of the box body 61 is a detachable structure with a snap-on connection to facilitate the disassembly of the flexible filter 63 and the cleaning of the lower dust collecting bin of the box body 61.

[0050] The flexible filter 63 can be gradually transferred from one box 61 to another box 61, so that the flexible filter 63 after filtering can be cleaned in the box 61 and then continued to be rolled up and stored. The flexible filter 63 above the ventilation hole of the cover plate 1 always maintains a good filtering effect, and can be used reciprocally for many times, avoiding frequent disassembly and replacement of new filters, thereby reducing maintenance costs.

[0051] The specific operating steps of the central air-conditioning system filtering device are as follows: when the air conditioner is not working, the filtering mechanism 6 can replace the filter and self-clean the used filter; the motor 1 624 drives the winding roller 623 to wind up the flexible filter 63 after filtering, and the cleaning brush 641 cleans the front and back sides of the filtering contaminated position of the flexible filter 63 rolled into the box 61; the dust head 1 651 cleans the corresponding cleaning brush 641, and the dust head 2 652 further performs dust cleaning operations on the front and back sides of the position cleaned by the flexible filter 63.

[0052] When the filter mechanism 6 needs to be replaced and thoroughly cleaned after being used for a long time, the operator operates the adjustment handle 221, and the stabilizing member 33 releases the restriction on the installation position of the cover plate 1 at the air inlet of the air conditioner, and the cover plate 1 is disassembled; the dust shield leaf 413 changes from a vertical state to a nearly horizontal inclined state in the adjustment bin of the sun-shaped frame 411, and the upper part of the ventilation hole of the cover plate 1 changes from an open state to a closed state, preventing the dust shaken off when replacing the filter mechanism 6 from polluting the clean environment; through multiple fan-shaped limit baffles 55, the limit on the two box bodies 61 is simultaneously released for disassembly.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
