As shown in fig. 1, the area within the housing 1 above the atomizing cartridge seal 4 may serve as a reservoir 102. Holes may be left in the atomizing wick seal 4 so that the tobacco tar in the reservoir 102 contacts the porous body 31. The tobacco tar in the reservoir chamber 102 can be sucked by the porous body 31, and then the tobacco tar is circulated to the heating element assembly.

To improve the sealing of the reservoir 102, the risk of leakage of liquid is reduced. The tubular structure 43 may be designed to provide a certain degree of sealing for the through hole 311, so as to separate the through hole 311 from the liquid storage cavity 102, and thus, the liquid in the liquid storage cavity 102 is not easy to leak from the through hole 311. The tubular structure 43 forms a seal between the through hole 311 and the plug part 111 to avoid problems with oil leakage between the tubular structure 43 and the through hole 311. The fixing and positioning reliability of the atomizing core sealing piece 4 and the atomizing core 3 as a whole can also be improved by inserting and fixing the insertion part 111 of the air outlet channel 11 in the tubular structure 43. Through the above-mentioned grafting cooperation relation, air outlet channel 11 directly communicates with atomizing chamber 20 through tubular structure 43 and through-hole 311, and this kind of gas circuit structure is smooth and easy, the bending is less, helps the gaseous outward outflow after the atomizing, reduces its cooling and forms the possibility of condensation liquid drop.

The matching structure of the sealing edge 431 and the step surface 110 can play a good role in sealing, and prevent liquid from passing through the gap between the air outlet channel 11 and the porous body 31 and further leaking into the through hole 311, the atomizing chamber 20 and the air outlet channel 11. The sealing rim 431 has a portion disposed around the edge of the suction surface and a portion disposed around the circumference of the through hole 311. The portion of the sealing rim surrounding the through hole 311 forms a seal between the step face 110 and the liquid-absorbing face. Specifically, the sealing rim 431 provides a sealing action between the liquid suction surface portion outside the orifice of the through-hole 311 and the step surface 110.
