[0002] Air purification devices, also known as "air cleaners", air fresheners, and purifiers, refer to household appliances that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), effectively improve the cleanliness of the air. They are mainly divided into household, commercial, industrial, and building. There are many different technologies and media in air purifiers, which enable them to provide clean and safe air to users. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, super-structured light mineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; material technologies mainly include: photocatalyst, activated carbon, extreme carbon core filter technology, synthetic fiber, HEAP high-efficiency material, negative ion generator, etc. Existing air purifiers are mostly composite, that is, they use multiple purification technologies and material media at the same time.

The inner convex of the cover plate 3 A plurality of mounting grooves 8 are provided on the block and are vertically distributed at equal intervals. Mounting blocks 9 are installed in the mounting grooves 8. The mounting grooves 8 and the mounting blocks 9 are both arranged in a trapezoidal structure. A dust collecting plate 10 is fixed on the mounting block 9. The dust collecting plate 10 is electrically connected to an external electrostatic generator through the mounting block 9 and the cover plate 3. The mounting block 9 and the mounting grooves 8 cooperate to mount the dust collecting plate 10 on the cover plate 3, and at the same time, the dust collecting plate 10 is easy to disassemble, clean and replace. A plurality of groups of symmetrically distributed baffles 11 are fixed on the inner wall on the other side of the dust collecting box 1. One end of the dust collecting plate 10 is located between two symmetrically distributed baffles 11. Damping pads are bonded on the sides of the two symmetrically arranged baffles 11 that are close to each other, so that the cooperation of the two baffles 11 can limit one end of the dust collecting plate 10, so that the dust collecting plate 10 can be stably installed.
[0027] Specifically, the other end of the dust box 1 is connected to the filter box 4, and a connecting frame 16 is arranged inside one end of the filter box 4. A filter screen plate 17 is inlaid on the inner side of the connecting frame 16, and the filter screen plate 17 is fixed by screws. The filter screen plate 17 plays a role in filtering residual dust. The outer side of the connecting frame 16 is connected to the inner wall of one end of the filter box 4 through an elastic sealing belt 18. The elastic sealing belt 18 plays a sealing role. Both ends of one side of the connecting frame 16 are connected to the other end of the dust box 1 through a plurality of elastic connecting rods 19 distributed in a linear array. The two sets of elastic connecting rods 19 cooperate to enable the connecting block 16 and the filter screen plate 17 to move back and forth horizontally.
