[0040] The basic working principle of this utility model is as follows: When the air purifier is turned on, the drive motor 23 in the fan assembly 2 starts to run, driving the impeller 24 in the fan housing 21 to rotate at high speed, forming a negative pressure suction force, which causes the left air intake hood 3 and the right air intake hood 4 on both sides of the body 1 to simultaneously draw in indoor air. The incoming air first passes through the left filter assembly 6 and the right filter assembly 7 for step-by-step filtration and purification. The nylon mesh filters out larger particulate impurities such as dust and hair, the HEPA filter efficiently intercepts PM2.5 and smaller particulate matter, bacteria, etc., and the activated carbon filter layer adsorbs formaldehyde, odors and some harmful substances in the air. The filtered air is compressed by the fan assembly 2 to the air outlet ring 22 at the top of the fan housing 21. The purified air is then discharged through the air outlet hood 5. The first air outlet grille 531, the second air outlet grille 541, the third air outlet grille 551, and the fourth air outlet area 56 guide the air to be discharged in four directions. The air is rotated 360° by the rotary motor 26 to improve the indoor air circulation efficiency. The left filter housing 61 and the right filter housing 71 can be easily disassembled and installed through the left disassembly port 11 and the right disassembly port 12 provided on the body 1, which facilitates users to regularly check and replace the filters.
