Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1-5, the air purifier of the present embodiment includes a housing 1, a filter screen assembly 2, an ionization module 3 and a fan assembly 4, the housing 1 is hollow and has a side opening 11, and the filter screen assembly 2 can be pulled out or pushed into the housing 1 through the side opening 11. The side wall of the filter screen assembly 2 is provided with a sliding groove 21 extending forwards and backwards, correspondingly, the inner wall of the shell 1 is provided with a sliding block 12 extending forwards and backwards to be matched with the sliding groove 21 in a guiding way, and the sliding groove 21 is close to the rear end and gradually increases from front to back in width to form a guiding part 211 so as to facilitate the insertion of the filter screen assembly 2 into the shell 1. The side opening 11 of the shell 1 is detachably connected with a side plate 10 which can cover the side opening 11, and the structure is convenient for assembling the shell 1 and disassembling and replacing the filter screen component 2.

In the present embodiment, as shown in fig. 2 and 3, a boss 13 capable of abutting against the upper edge of the screen assembly 2 is formed on the inner wall of the housing 1. Ionization module 3 is used for producing the anion, locates in casing 1 and is located filter screen subassembly 2 below, encloses jointly between the upper edge of boss 13 and ionization module 3 and becomes the U-shaped double-layered groove 14 that can be wherein with filter screen subassembly 2 centre gripping, and the opening of U-shaped double-layered groove 14 is arranged forward, and this structure can be retrained filter screen subassembly 2's position on the whole, improves the leakproofness of filter screen subassembly 2 in casing 1.
