In this way, the air coming in from the lower housing 3 can be concentrated and guided to the inside of the impeller 16, and the air intake forms a stable airflow under the drive of the motor 15, so as to stably output purified air.

[0028] like Figure 1 , Figure 2 As shown, a plurality of air inlet mesh holes 31 are evenly provided on the side wall of the lower shell 3, so that the air purifier of the utility model forms a 360-degree annular air inlet, so that the filter element 4 can filter the air in a 360-degree direction, greatly improving the utilization rate and service life of the filter element 4.

[0029] The top cover 12, the middle shell 2, the lower shell 3, and the frame 14 in the utility model are preferably made of plastic materials such as ABS, PP, PC, etc., and the thickness of the side of the top cover 12, the annular shell 143, the middle shell 2, and the lower shell 3 is preferably 1-2 mm, so that the top cover 12, the middle shell 2, the lower shell 3, and the annular shell 143 all have good elasticity and are easier to operate during installation and disassembly.

[0030] Furthermore, in order to facilitate the disassembly of the fan mechanism 1 and the middle shell 2, the utility model can also be configured with a prying tool with a thin blade. When the fan mechanism 1 needs to be removed from the middle shell 2, the prying tool is inserted into the gap between the top cover 12 and the middle shell 2, and the top end of the middle shell 2 is pried, so that the middle shell 2, the top cover 12 and the annular shell 143 are elastically deformed, thereby disengaging the protruding clamping portion 21 from the clamping hole 11, and then the fan mechanism 1 is taken out from the middle shell 2.
