Specifically, the preheating part 16 is electrically connected with the main machine 2 through the connecting seat 15, and self-heating is realized through energy supply of a battery of the main machine 2; that is, the preheating member 16 is used to generate heat after energization. For example, the connecting socket 15 may include two conductive elements sleeved on each other and insulated from each other, and the two conductive elements respectively connect the positive and negative electrodes of the preheating part 16 to the main unit 2. The manner of electrically connecting the preheating part 16 to the host 2 through the connecting seat 15 can refer to the manner of electrically connecting the heating element 14 to the host 2 through the connecting seat 15, and will not be described in detail. The preheating part 16 is arranged in parallel with the vent pipe 13, and the preheating part 16 is fixed on the vent pipe 13 and/or the connecting seat 15.
