[0018] In summary, this utility model has the following advantages:

[0019] 1. This utility model, by setting up a filter assembly, allows the motor to be started when the filter plate needs cleaning. The motor drives the cam to rotate, causing the cam to continuously strike the return frame, which in turn causes the toothed plate to move back and forth. This causes the gear to deflect back and forth, resulting in the brush plate deflecting back and forth and brushing the surface of the filter plate. Dust and impurities are brushed into the collection box for collection. Then, the driving helical gear is rotated, causing the driven helical gear to drive the bidirectional threaded rod to rotate. This causes the fixed cylinder to move along the threaded rod, thereby disconnecting the collection box from the discharge chute and cleaning the impurities in the collection box.

[0020] 2. By setting up a replacement component, if the filter plate is damaged and needs to be replaced, the second helical gear is rotated, causing the first helical gear to rotate, which in turn causes the bidirectional lead screw to rotate. This causes the limiting cylinder to move along the bidirectional lead screw, thereby disconnecting the connection between the mounting block and the filter box. Then, the filter plate is lifted upwards, making it convenient to replace and install the filter plate. Attached Figure Description

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0030] Example:

[0031] Please combine Figures 1-6 This embodiment of a high-rise building air supply system includes a building body 1, an exhaust pipe 2 connected at equal intervals on the left side of the building body 1, an air collection box 3 connected to the left side of the exhaust pipe 2, an air inlet pipe 4 connected at equal intervals on the right side of the building body 1, an air supply box 25 connected to the right end of the air inlet pipe 4, a heating box 5 connected to the right side of the air supply box 25, a filter assembly connected to the right side of the heating box 5 and the output end of the air collection box 3, and a fan box 6 connected to the right side of the right filter assembly.

[0032] The filter assembly is used to filter and collect dust and impurities. The filter assembly includes a filter box 7, with a straight groove at the bottom. A collection component is fixedly connected to the bottom of the filter box 7. The collection component includes a discharge chute, with a collection box 22 slidably connected inside the discharge chute. A limiting groove is provided on the front of the collection box 22, and a bidirectional threaded rod 23 is installed inside the limiting groove. Two seated bearings are mounted on the surface of the bidirectional threaded rod 23, and the bottoms of the seated bearings are fixedly connected to the bottom of the inner wall of the limiting groove, ensuring the normal operation of the bidirectional threaded rod 23. Two fixed cylinders 24 are meshed with the surface of the bidirectional threaded rod 23, and two retaining strips are fixedly connected to the surface of the fixed cylinders 24. The inner wall of the limiting groove has openings for the fixed cylinders 24 and retaining strips to pass through, and the inner wall of the discharge chute has slots for the fixed cylinders 24 and retaining strips to be inserted, facilitating the limiting connection between the fixed cylinders 24 and the discharge chute. A driven helical gear is sleeved on the surface of the bidirectional threaded rod 23. The surface is meshed with a drive helical gear, which facilitates the control of the movement of the fixed cylinder 24. The collecting component is located below the straight groove. A protective cover 8 is installed on the top of the filter box 7. A motor 9 is installed inside the protective cover 8. One end of the output shaft of the motor 9 is rotatably connected to the inner wall of the protective cover 8. A cam 10 is sleeved on the outer side of the output shaft of the motor 9. A U-shaped frame 11 is abutted on the surface of the cam 10. A toothed plate 12 is fixedly connected to the bottom of the U-shaped frame 11. A groove is opened at the bottom of the toothed plate 12. A guide rail is slidably connected inside the groove. The bottom of the guide rail is fixedly connected to the top of the filter box 7 to ensure the normal movement of the toothed plate 12. Gears 13 are meshed at equal intervals on the surface of the toothed plate 12. A brush plate 14 is fixedly connected to the shaft at the bottom of the gear 13 through a rotating rod. A fixing block is rotatably connected to the bottom of the brush plate 14. Both sides of the fixing block are fixedly connected to the inner wall of the straight groove to ensure the normal operation of the brush plate 14. A replacement component is installed inside the filter box 7.

[0033] The replacement assembly facilitates the replacement of the filter plate 16. The replacement assembly includes two sliding plates 15 fixedly connected to the front and back of the filter box 7, with the filter plate 16 installed between the two sliding plates 15. Vertical plates are provided on both the front and back of the filter plate 16, slidingly positioned inside the sliding plates 15 for easy positioning of the filter plate 16. The surface of the brush plate 14 abuts against one side of the filter plate 16. A mounting block 17 is fixedly connected to the top of the filter plate 16, with a rubber sealing ring fitted onto the surface of the mounting block 17 to prevent gas leakage. The mounting block 17 has an installation groove inside, with openings on both the front and back of the inner wall of the groove. The filter box 7 has a round opening through which the limiting cylinder 19 passes. The top of the filter box 7 has a square groove. The inner wall of the square groove has a contact port for the limiting cylinder 19 to abut against, so that the mounting block 17 can be connected to the filter box 7. A bidirectional screw rod 18 is installed inside the mounting groove. Two symmetrically arranged limiting cylinders 19 are threadedly connected to the surface of the bidirectional screw rod 18. A locking block is fixedly connected to the bottom of the limiting cylinder 19. A locking groove for the locking block to move is opened at the bottom of the inner wall of the mounting groove, so as to ensure the normal movement of the limiting cylinder 19. A first helical gear 20 is sleeved on the surface of the bidirectional screw rod 18. A second helical gear 21 is meshed on the surface of the first helical gear 20.

[0034] The implementation principle of a high-rise building air supply system in this application embodiment is as follows: During use, the system supplies air to the filter box 7 on the left through the fan box 6. The air temperature is controlled by the heating box 5. The air is then delivered to the air supply box 25. The air supply box 25 delivers the air to different rooms in the main building 1 through the air inlet pipe 4. The air in the main building 1 is drawn into the air collection box 3 through the air collection box 3 and the exhaust pipe 2, and then discharged to the filter box 7 on the left, thereby forming an air circulation in the room.

[0035] When cleaning the filter plate 16 is required, the motor 9 is started, causing the motor 9 to rotate the cam 10. This causes the cam 10 to continuously strike the retaining frame 11, causing the toothed plate 12 to move back and forth. This causes the gear 13 to deflect back and forth, causing the brush plate 14 to deflect back and forth, brushing the surface of the filter plate 16 back and forth. This brushes the dust and impurities into the collection box 22 for collection. Then, the driving helical gear is rotated, causing the driven helical gear to rotate the bidirectional threaded rod 23. This causes the fixed cylinder 24 to move along the bidirectional threaded rod 23, thereby disconnecting the collection box 22 from the discharge chute and cleaning the impurities in the collection box 22. This process is very convenient.

[0036] If the filter plate 16 is damaged and needs to be replaced, rotate the second helical gear 21 to make the first helical gear 20 rotate, thereby making the bidirectional lead screw 18 rotate, and making the limiting cylinder 19 move along the bidirectional lead screw 18, thereby disengaging the connection between the mounting block 17 and the filter box 7. Then lift the filter plate 16 upward to facilitate the replacement and installation of the filter plate 16.
