Therefore, the atomization amount of the aerosol produced by the atomizer 10 in the first position is greater than the atomization amount of the aerosol produced by the atomizer 10 in the second position. Therefore, the air inlet area of the first main machine air inlet 21a is larger than the air inlet area of the second main machine air inlet 21b, which can provide a larger air intake amount for the atomizer 10 when the atomization amount is large. When the atomization volume is small, a smaller air intake volume is provided to the atomizer 10 so that the atomization volume matches the air intake volume and the user's suction experience is improved.

Optionally, in this embodiment, the first main machine air inlet 21a includes a plurality of sub-air inlets 21c, and the air inlet area of the second main machine air inlet 21b is the same as the air inlet area of any sub-air inlet 21c. For example, the first main engine air inlet 21a includes two sub-air inlets 21c. The two sub-air inlets 21c have the same air inlet area. The second main engine air inlet 21b has the same air inlet area as the two sub-air inlets 21c.
