Preferably, the heating body 211 of the heating member may be a ceramic electric heating tube, an infrared heating tube, a carbon tube, or a PTC heating body 211.
The infrared heating pipe generates electromagnetic waves by utilizing the infrared spectrum radiation principle, so that the surrounding air is heated and warmed, and compared with a resistance wire heating pipe, the safety of the infrared heating pipe is better, and the heating is uniform and quick. The ceramic electric heating tube is internally provided with an alloy wire penetrating and winding and a ceramic block, and the shell is wrapped by metal. The carbon element heating tube is at the oil heater, the heating wire, technical innovation has been carried out on the basis of traditional heating methods such as halogen lamp, no matter be in the security, the comfort level, all the more winning in the power saving degree, light is soft not dazzling when generating heat, it is very comfortable to get warm, can not produce the drying, uncomfortable feelings such as ardor, in addition, life is also longer, this kind of heating method of more important thing also has the efficiency of far infrared physiotherapy, on the whole, the carbon element heating tube is obviously healthier than other modes, safety, the carbon element heating tube can accomplish 3 seconds fast heat even, and send heat on a large scale, and the heating efficiency is high.

In addition, the PTC heater is light in overall appearance and convenient to assemble in the whole machine. Further, the first and second heating members 210 and 220 are detachably mounted to the inner cavity, and thus, may be selectively mounted to the inner cavity according to a use scenario.
According to the technical scheme, the second heating element 220 is additionally arranged at the fresh air inlet 110, and the second heating element 220 can be directly heated to prevent the fresh air inlet 110 from being frozen.
