[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0020] according to Figure 1-5 As shown, this embodiment proposes an air filtering device for an energy-saving air-conditioning unit, including a box body 1, a protective net 2, a cover plate 3 and an air outlet 4. A protective net 2 is provided at the bottom of the left side of the box body 1, and a cover plate 3 is provided on the right side of the box body 1. The cover plate 3 is connected to the air outlet 4. A filter cartridge 9 is provided inside the box body 1, and an automatic cleaning mechanism is provided inside the filter cartridge 9. The bottom of the filter cartridge 9 is fixedly connected to a bottom cover 5. The box body 1 is connected to the air inlet duct of the air-conditioning unit, and the new air refluxed and inhaled in the air conditioner passes through the protective net 2 into the interior of the box body 1. The filter cartridge 9 can filter the air entering the interior of the box body 1 and separate the air from dust. The air passes through the filter cartridge 9 and is discharged to the outside through the air outlet 4, while the dust adheres to the inner wall of the filter cartridge 9. After that, the dust on the inner wall of the filter cartridge 9 is automatically cleaned out of the outside of the box body 1 by the automatic cleaning mechanism, so as to extend the service life of the filter cartridge 9.

[0021] The automatic cleaning mechanism includes a bottom cover 5, a top cover 8, a rotating shaft 10, a scraper plate 11 and a connecting frame 15. The top of the filter cartridge 9 is covered with the top cover 8. The bottom of the top cover 8 is rotatably connected to the rotating shaft 10. The outer side of the rotating shaft 10 is symmetrically fixedly connected to the connecting frame 15. One side of the connecting frame 15 is fixedly connected to the scraper plate 11.

[0022] The outer wall of the scraper plate 11 is in close contact with the inner wall of the filter cartridge 9 . A rotary motor 12 is fixedly mounted on the top of the top cover 8 . The output end of the rotary motor 12 is fixedly connected to the top end of the rotating shaft 10 .

[0023] The output end of the rotating motor 12 can drive the rotating shaft 10 to rotate inside the filter cartridge 9. The scraper plate 11 is connected to the rotating shaft 10 through the connecting frame 15, and the outer wall of the scraper plate 11 fits the inner wall of the filter cartridge 9. The rotating shaft 10 drives the scraper plate 11 to rotate inside the filter cartridge 9 through the connecting frame 15, and at the same time scrapes off the dust inside the filter cartridge 9.

[0024] There are multiple partition plates 13 equidistantly distributed in an annular pattern on the inner side of the bottom cover 5, and the positions of adjacent partition plates 13 are staggered up and down. A discharge pipe 6 is fixedly connected to the inside of the bottom cover 5, and a guide hopper 7 is fixedly connected to the top of the discharge pipe 6. Air enters the bottom of the box body 1 through the protective net 2, and then passes through the bottom cover 5 into the interior of the filter cartridge 9. There are multiple partition plates 13 staggered up and down inside the bottom cover 5. The air flows into the filter cartridge 9 from the staggered gaps. The protective net 2 and the partition plates 13 both play a protective role to prevent larger external objects from invading the interior of the box body 1.

[0025] The diameter of the top of the guide hopper 7 is smaller than the diameter of the top of the filter cartridge 9. The bottom end of the scraper plate 11 is fitted and connected to the top of the guide hopper 7. The bottom end of the discharge pipe 6 passes through the bottom of the discharge box 1. The rotating shaft 10 drives the scraper plate 11 to rotate through the connecting frame 15. The centrifugal force generated can drive the scraped dust to flow toward the center of the filter cartridge 9, so that the dust falls into the inside of the guide hopper 7 and is discharged to the outside of the box 1 through the discharge pipe 6.

[0026] The outer side of the bottom cover 5 is symmetrically fixedly connected with a fixing rod 14, and the inner side and top end of the fixing rod 14 are respectively fitted and connected to the outer side of the filter cartridge 9 and the top of the top cover 8. The top end of the fixing rod 14 is detachably connected to the top cover 8 by a bolt. The material of the fixing rod 14 is an elastic steel sheet. When installing the top cover 8, the two fixing rods 14 can be moved to the two sides of the filter cartridge 9 respectively to increase the distance between the two fixing rods 14. The top cover 8 can pass through the fixing rod 14 to cover the top of the filter cartridge 9. Thereafter, the bolt on the top of the fixing rod 14 is screwed into the interior of the top cover 8 to fix the top cover 8 to the top of the filter cartridge 9.

[0027] A group of threaded holes are provided on both sides of the box body 1, and a group of bolts are symmetrically provided on both sides of the protective net 2 and the cover plate 3. The protective net 2 and the cover plate 3 are detachably connected to the two sides of the box body 1 through the bolts.

[0028] In the air filtering device of the energy-saving air-conditioning unit, the output end of the rotating motor 12 can drive the rotating shaft 10 to rotate inside the filter cartridge 9, the scraper plate 11 is connected to the rotating shaft 10 through the connecting frame 15, and the outer wall of the scraper plate 11 is in contact with the inner wall of the filter cartridge 9, the rotating shaft 10 drives the scraper plate 11 to rotate inside the filter cartridge 9 through the connecting frame 15, and at the same time scrapes off the dust inside the filter cartridge 9. The centrifugal force generated by the rotation of the scraper plate 11 driven by the rotating shaft 10 through the connecting frame 15 can drive the scraped dust to flow toward the center of the filter cartridge 9, so that the dust falls into the inside of the guide hopper 7 and is discharged to the outside of the box body 1 through the discharge pipe 6, so as to extend the service life of the filter cartridge 9.
