[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Please combine Figure 1-Figure 4 A dust removal device for an air purifier of the present embodiment includes an air purifier 1, an air inlet is provided on one side of the air purifier 1, a filter plate 2 for filtering air is provided inside the air purifier 1, a cleaning component for cleaning dust on the surface of the filter plate 2 is provided on one side of the filter plate 2, a driving component for driving the cleaning component to move when the air purifier 1 is working is provided on one side of the cleaning component, and a collecting component for collecting dust cleaned by the cleaning component is provided at the bottom of the filter plate 2.

[0027] Combination Figure 2A limiting plate 6 is fixedly installed on one side of the air inlet, and the limiting plate 6 is arranged in a "mouth" shape. The filter plate 2 is fixedly installed inside the limiting plate 6. A collecting port is opened at the bottom of one side of the limiting plate 6. The limiting plate 6 is connected with the air inlet, so that the filter plate 2 can filter the incoming air.

[0028] Combination Figure 2 and Figure 3 The cleaning component includes two pushing plates 301 arranged on one side of the filter plate 2 and a plurality of impact columns 302 fixedly installed on one side of each pushing plate 301. A rubber ball 7 is rotatably installed on one end of each impact column 302. Sliding blocks 8 are fixedly installed on both ends of the two pushing plates 301. One side of each sliding block 8 is slidably matched with a sliding bar 9 fixedly installed on the inner wall of the limiting plate 6. After the pushing plate 301 moves and resets, the impact column 302 will push the rubber ball 7 to knock on the filter plate 2 to let the dust on the filter plate 2 fall.

[0029] Combination Figure 2 and Figure 3 The driving assembly includes a driving cloth 401 arranged on one side of the two pushing plates 301, a connecting block 402 fixedly installed on one side of each sliding bar 9, and a pushing spring 403 fixedly installed on one side of each connecting block 402. Both sides of the driving cloth 401 are fixedly installed on one side of the adjacent pushing plate 301, and one end of each pushing spring 403 is fixedly installed on one side of the adjacent pushing plate 301. After the filter plate 2 filters the air, the air will blow the driving cloth 401, allowing the driving cloth 401 to pull the pushing plate 301 to move, so that the cleaning assembly can clean the filter plate 2 when resetting.

[0030] Combination Figure 2 and Figure 4 The collection component includes a collection box 501 slidably arranged on one side of the inner wall of the limiting plate 6 and two sticky plates 502 fixedly installed inside the collection box 501 for sticking dust. The collection box 501 slides with the limiting plate 6 through the collection port. A sliding groove adapted to the filter plate 2 is provided on one side of the collection box 501. The collection box 501 is slidably plugged with the filter plate 2 through the sliding groove. The collection box 501 can be taken out from the inside of the air purifier 1 to clean the collected dust.

[0031] The implementation principle of a dust removal device for an air purifier in the embodiment of the present application is as follows: when the air purifier 1 is turned on, the air will pass through the air inlet and the filter plate 2 to be filtered, and the filtered air will also blow up the driving cloth 401. After the driving cloth 401 like a sail is blown up, it will pull the push plate 301 to move, and the moved push plate 301 will squeeze the push spring 403. In this way, when the air purifier 1 is turned off, the driving cloth 401 will lose the blowing force and will not be able to continue to pull the push plate 301. The push plate 301 will be reset under the push of the push spring 403, and the reset push plate 301 will When the impact column 302 is pushed to move, the rubber ball 7 at one end of the impact column 302 will knock on the filter plate 2. The vibration of the knocking will cause the filter plate 2 to vibrate, thereby shaking the dust on the filter plate 2 off, and the falling dust will fall into the collection box 501 and be collected. Moreover, since the rubber ball 7 itself has a certain elasticity, combined with the elastic force of the pushing spring 403, the rebound force after hitting the filter plate 2 will knock on the filter plate 2 for many times. Although the knocking force will become smaller and smaller, such high-frequency vibration makes it easy to shake the dust off the filter plate 2. This arrangement can make the filter plate 2 have an automatic cleaning effect.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
