In this process, the driving source 310 is used to drive the wind wheel 320 to rotate, so that the air completes the purification cycle in the air purifier.

In addition, in the above-described air cleaner, the bracket 330 of the wind wheel assembly 300 is used to support the driving source 310, and the two supporting parts 210 of the air intake part 200 are used to support the bracket 330, so that the driving source 310 can be supported in the first receiving chamber 110. Because the two supporting portions 210 of the air inlet component 200 are spaced and oppositely disposed in the first accommodating cavity 110, and the wind wheel 320 is disposed between the two supporting portions 210, the side wall of the first accommodating cavity 110 and the two supporting portions 210 can be enclosed in the wind wheel 320 to form an air duct communicated with the air outlet 120, during the rotation of the wind wheel 320, the air purified in the air purifier can flow to the air outlet 120 through the air duct, and further flow to the outside, so as to achieve the purpose of purifying the outside air.

And because the wind wheel 320 and the air inlet component main body 220 are arranged at intervals, the volume of the space area around the wind wheel 320 can be further increased, so that the pressure intensity in the air duct is further reduced, the noise of air flowing in the air duct is reduced, and the noise of the air purifier is reduced. And because the wind wheel 320 can cover the plurality of first air inlets 221, when the wind wheel 320 rotates, the air in the air purifier does not form turbulent flow.
