DETAILED DESCRIPTION

[0021] like Figures 1 to 3As shown, the utility model is an air filter device, comprising a filter housing 1, wherein the filter housing 1 is connected with a filter self-cleaning device 2, and the filter self-cleaning device 2 is used to clean the filter 22 so that the filter 22 can continuously filter the air. The filter self-cleaning device 2 comprises: a filter 22, a motor 21, a first gear 23, a second gear 24, a threaded rod 25, a rotating block 26, a slide rail 28, a cleaning plate 27 and a support rod 29. The filter housing 1 is provided with a through slot 8, and the through slot 8 is for air to pass through. The filter 22 is located at the mouth of the through slot 8, and the filter 22 is used to intercept dust in the air. The motor 21 is located outside the filter housing 1 and is fixedly connected to the filter housing 1. The output shaft of the motor 21 passes through the filter housing 1 and is fixedly connected to the center of the first gear 23, and the motor 21 drives the first gear 23 to rotate. The threaded rod 25 is located inside the filter housing 1 and is rotatably connected to the filter housing 1. The threaded rod 25 passes through the second gear 24 and is fixedly connected to the second gear 24, and the second gear 24 is meshed with the first gear 23. The first gear 23 and the second gear 24 are driven to rotate by the motor 21. The threaded rod 25 passes through the rotating block 26 and is threadedly connected to the rotating block 26. The side of the rotating block 26 is fixedly connected to the support rod 29. The side of the filter 22 is fixedly connected to the slide rail 28. The support rod 29 is slidably connected to the slide rail 28. The rotating block 26 is moved up or down by the rotation of the threaded rod 25, and the cleaning plate 27 is driven to move, so that the cleaning plate 27 scrapes the dust on the filter 22. The cleaning plate 27 is fixedly connected to the side of the rotating block 26. The side of the cleaning plate 27 close to the filter plate is connected to a brush 6, and the brush 6 has multiple layers. The filter 22 is cleaned by the multiple layers of brushes 6. A dust outlet groove 7 is provided at the bottom of the filter housing 1, and dust falls into the dust outlet groove 7 and enters the dust inlet groove 3 through the dust outlet groove 7. The lower part of the dust outlet groove 7 is connected to the dust inlet groove 3, and the dust inlet groove 3 is conical, which is conducive to the falling of dust, and the lower end of the dust inlet groove 3 is connected to the dust collector 4. The inside of the filter housing 1 is connected to a protective net 5, which is used to protect large foreign objects from damaging the internal structure of the filter housing 1. The number of meshes of the protective net 5 is greater than that of the filter net 22.

[0022] The working process of the above scheme is as follows: the motor 21 is started to drive the first gear 23 to rotate forward, and the first gear 23 drives the second gear 24 and the threaded rod 25 to rotate. At this time, the rotating block 26 is prevented from rotating by the support rod 29 and the slide rail 28, and the rotating block 26 moves upward to drive the cleaning plate 27 to move so that the brush 6 scrapes off the dust. When the brush 6 needs to move downward, the motor 21 is started to reverse the motor 21 to drive the cleaning plate 27 and other components to move toward the dust inlet groove 3. When the dust falls into the dust inlet groove 3, the vacuum cleaner 4 is started to collect the dust.

[0023] The above scheme has the beneficial effects of: scraping out impurities on the filter 22 through the filtering self-cleaning device 2, so that the filter 22 continues to filter impurities in the air; after the impurities are scraped out by the filtering self-cleaning device 2, the dust is collected by the vacuum cleaner 4 to prevent the dust from clogging the filter 22 again; and the dust is scraped out by the multi-layer brush 6.

[0024] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
