[0037] The four groups of filter assemblies 4 can make the filter structure have a multi-layer air purification and filtration effect, effectively filter the air in multiple layers, improve the air purification and filtration quality, and ensure the multi-layer filtration and purification effect of the air;

[0038] When it is necessary to replace and install the single filter assembly 4, the secondary installation holes 404 of the filter assembly 4 can be rotated and removed from the screws in the primary fixed holes 3.

[0039] After the screws are removed, the filter frame 401 and the filter screen 402 can be manually pulled out through the installation plate 403, so that the targeted removal work of the filter assembly 4 can be completed.

[0040] When it is necessary to install a new filter assembly 4, the filter frame 401 can be inserted into the installation slot 2 on the side of the filter core shell 1, and after insertion, the filter assembly 4 is manually pushed, and after the filter assembly 4 is completely inserted into the inside of the filter core shell 1, the filter frame 401 of the filter assembly 4 can be inserted into the clamping slot of the corresponding end clamping piece 5, so that the end clamping piece 5 can limit the end clamping slot of the filter frame 401, so that the end of the filter frame 401 does not swing in the filter core shell 1, and has good use stability.

[0041] When the filter frame 401 is completely inserted into the inside of the filter core shell 1, the secondary installation holes 404 of the installation plate 403 can be aligned with the primary fixed holes 3 of the corresponding installation slot 2, and then screws for fixing are installed in the secondary installation holes 404 and the primary fixed holes 3, so that the installation work of the filter assembly 4 can be completed.

[0042] In summary, the filter structure has a multi-layer air purification and filtration effect, can effectively filter the air in multiple layers, improve the air purification and filtration quality, and when the filter assembly 4 needs to be repaired or replaced, the targeted disassembly and installation work can be conveniently carried out, has the use characteristics of quick installation and quick disassembly of the filter screen structure, and improves the repair and maintenance efficiency of the filter screen.

[0043] Meanwhile, the targeted filter screen dismounting and mounting has targeted maintenance effect, when a single filter screen structure needs to be replaced, the whole filter structure assembly does not need to be replaced, only the corresponding filter assembly 4 needs to be dismounted and replaced, effectively improving the comprehensive utilization efficiency of other filter screens, avoiding structure use waste, targeted filter screen replacement work can be carried out, reducing maintenance cost, effectively reducing the overall use and maintenance cost of the purifier in actual use, and having good structure use effect.
