The heating device is always arranged in the air duct, so that the wind resistance is increased, the energy consumption is increased, the noise is larger, and the mute work is not facilitated.

In addition, 202021296216.4 discloses and reports an air cleaner in which a fan moves in synchronization with a first housing, and a first driving member and a second driving member are provided so that a filter screen assembly and a heating assembly can form a fan passage through which the fan passes. The impeller drives the first shell and the fan to move towards the second shell, when the impeller moves to the purification position, the filter screen assembly and the heating assembly enter a non-working state, and at the moment, the whole device only carries out electric purification operation. And because filter screen subassembly and heating element have formed the fan passageway that supplies external wind to get into this moment, the volume of wind effect on heating element will significantly reduce to can effectually avoid effects such as wind to heating element's pollution. Because first casing can move at vertical direction for the second relatively, consequently when needs accomodate air purifier, control between the first casing move to purify the position can, this time air purifier's whole height will reduce to be convenient for accomodate. The disadvantages of the prior art are that the structure is too complex, the volume is large, the production and the assembly are not facilitated, and the cost is too high.
