The control module 724 in the high-voltage electrostatic purifier 72 applies voltage to the ozone generating assembly 726, and the ozone generating assembly 726 ionizes air to generate ozone, so that the ozone sterilizes the air. Then, the gas enters the dryer 80, the drying device 84 in the dryer 80 heats or absorbs the gas, so that the gas is not easy to generate condensed water, finally the gas flows into the activated carbon filter purifier 74, the gas in the activated carbon filter purifier 74 passes through the activated carbon module 744 and the smoke exhaust port 24, and the smoke exhaust port 24 exhausts clean gas.
