The cooperation of the fixing frame 904, the fixing strip 905, the fixing frame 906 and the fixing groove 907 facilitates the disassembly and replacement of the non-woven filter layer 901, the activated carbon filter layer 902 and the antibacterial fiber layer 903. The setting is such that by regularly replacing the air outlet filter cloth 1007, the air outlet filter cloth 1007 is prevented from being blocked after long-term use, which affects the filtering and air outlet effects. The replacement process of the air outlet filter cloth 1007 can be automated, thereby improving work efficiency. Through the setting of the fixing component 11, the limit block 1106 on the outside of the support frame 1105 is clamped in the limit groove 1103, so that the cover plate 6 is firmly fixed on the top of the shell 1, thereby improving the sealing of the device, and making it convenient for users to disassemble it, thereby reducing the time required for replacing components.
