The atomizing assembly 30 is fitted within the atomizing chamber 40 for atomizing and generating an aerosol-generating substrate within the atomizing chamber 40 for entrainment with ambient air entering through the air inlet 131.

Moreover, the base 10 further has a drainage channel 133 and a liquid storage channel 135, the two opposite ends of the drainage channel 133 are respectively communicated with the air inlet 131 and the liquid storage channel 135, the liquid storage channel 135 is opened on the outer peripheral surface of the base 10, and the drainage channel 133 is configured to drain the liquid medium flowing to the air inlet 131 to the liquid storage channel 135 by capillary force.

The outer peripheral face, the surface that indicates the periphery wall of pedestal 10, under normal condition, the outer peripheral face that is located the inside atomizing chamber 40 of pedestal 10 and periphery wall does not communicate, and this application is through setting up drainage channel 133 in air inlet 131 department for atomizing chamber 40, air inlet 131, drainage channel 133 and stock solution passageway 135 have realized the intercommunication, avoid the aerosol in the atomizing chamber 40 to generate liquid medium such as matrix or condensate to leak to electrical component from air inlet 131.

When the liquid medium on the inner wall of the second gas inlet 1312 is too much collected, the liquid medium flows to the first gas inlet 1311 side along the gravity direction, and the flow guide channel 133 extends to the step surface between the first gas inlet 1311 and the second gas inlet 1312, so that the liquid medium can be intercepted and guided between the first gas inlet 1311 and the second gas inlet 1312, and the leakage prevention effect is further improved.
