particles of dust separated from the activated carbon filter plate 2 are discharged through the collection port 13, the smaller particles of dust are gradually settled when the air purifier is not in operation and discharged from the collection port 13, so that the next work of the air purifier is not affected, the tapered collection port 13 can facilitate the dust to enter the collection box 17 through the collection port 13, meanwhile, because the diameter of the bottom end of the collection port 13 is smaller, the dust in the collection box 17 is not easy to enter the shell 1 through the collection port 13, thereby reducing the blockage of the dust on the activated carbon filter plate 2, improving the air purification efficiency, after the work of the air purifier is finished, a user can clean the dust in the collection box 17 by taking out the collection box 17, facilitating the use of the user, and improving the dust cleaning efficiency, the hinged plate 33 pushes the inclined active carbon filter plate 2 to vibrate, and the active carbon filter plate 2 slides along the sliding groove 21, so that the vibration amplitude of the active carbon filter plate 2 is increased, the dust separation efficiency on the active carbon filter plate 2 is improved, meanwhile, the second spring 22 is extruded when the active carbon filter plate 2 slides in the sliding groove 21, the second spring 22 absorbs the vibration energy of the active carbon filter plate 2, so that the active carbon filter plate 2 is prevented from being damaged when vibrating, the service life of the active carbon filter plate 2 is prolonged, the use cost of the air purifier is reduced, the second spring 22 and the active carbon filter plate 2 reset in the sliding groove 21, the active carbon filter plate 2 is ensured to be contacted with the hinged plate 33, the structural stability is improved, when air flow passes through the scraping module 4, the connecting plate 43 is blown, so that the connecting plate 43 rotates on the mounting rod 41, the third spring 42 extends due to the centrifugal force when the connecting plate 43 rotates, when the connecting plate 43 is close to the activated carbon filter plate 2, it contacts with the activated carbon filter plate 2, further increasing the vibration amplitude of the activated carbon filter plate 2, increasing the separation speed of dust on the activated carbon filter plate 2, meanwhile, the rubber pad 44 on the connecting plate 43 can scrape off stubborn dust adhered on the activated carbon filter plate 2 when contacting the activated carbon filter plate 2, and the rubber pad 44 is soft and does not damage the activated carbon filter plate 2, thereby preventing dust from accumulating on the active carbon filter plate 2 and improving the ventilation efficiency of the active carbon filter plate 2, when the hinged plate 33 is contacted with the active carbon filter plate 2, because the activated carbon box 25 is provided with a plurality of activated carbon boxes 25, the single activated carbon box 25 has smaller volume and smaller mass, so that the activated carbon box 25 closest to the hinged plate 33 has larger vibration amplitude, thereby increasing the vibration amplitude of the activated carbon adsorbent 27 in the activated carbon cartridge 25, increasing the contact area between the activated carbon adsorbent 27 and the air, further improving the adsorption effect of the activated carbon adsorbent 27, when the activated carbon adsorbent 27 vibrates, the air flow can more easily take away the moisture adsorbed in the activated carbon adsorbent 27, so as to further improve the adsorption effect of the activated carbon adsorbent 27, when the individual activated carbon cartridges 25 vibrate, the portions of the elastic cord 28 within the activated carbon cartridges 25 are caused to vibrate, thereby causing the entire elastic cord 28 to vibrate, so that the elastic rope 28 stirs the activated carbon adsorbents 27 in the other activated carbon boxes 25, further increasing the vibration amplitude of the activated carbon adsorbents 27 in the activated carbon boxes 25, thereby increasing the contact area of the activated carbon adsorbent 27 and the air, further improving the adsorption effect of the activated carbon adsorbent 27, the air flow more easily takes away the moisture adsorbed in the activated carbon adsorbent 27 when the activated carbon vibrates, and the adsorption effect of the activated carbon adsorbent 27 is further improved.
