The bottom cover 30 is provided with an air inlet hole 32 connected to the air inlet end of the atomizer 20. The positions of the air inlet holes 32 and the positions of the mounting holes 31 are staggered and do not affect each other. The inlet of the intake hole 32 is the above-described intake port 101.

Preferably, as shown in fig. 2 and 6, the bottom cover 30 is connected with the card slot of the housing 10 through a buckle 301, and can be installed without tools.

Specifically, the bottom cover 30 is a bowl-shaped structure, and the latch 301 is disposed on the outer surface. The end of the bottom cover 30 is stopped against the sealing member 12, and part of the structure of the sealing member 12 is placed in the bowl-shaped structure of the bottom cover 30, so that the sealing member 12 is firmly fixed and is not easy to shift and deform.

One part of the outer wall of the sealing element 12 is arranged in a sealing way with the shell 10, the other part of the outer wall of the sealing element 12 is arranged in the bowl-shaped structure of the bottom cover 30, and the middle of the sealing element 12 is connected with the atomizing core 20 in a sealing way, so that the sealing element 12 can be firmly fixed, multiple sealing is realized, and the phenomenon of oil leakage is not easy to occur even if the sealing element is deformed.

Specifically, as shown in fig. 2 to 5, the sealing member 12 includes a sealing portion 1201 sealingly connected to the housing 10, and a mounting portion 1202 fixedly connected to the bottom cover 30. The outside of sealing portion 1201 is provided with the arch to convenient and casing 10 inner wall sealing connection makes to possess sealed effect between sealing portion 1201 and the casing 10, prevents that the tobacco tar from revealing. One surface of the sealing part 1201 facing the reservoir 11 is an inner wall of the reservoir 11, and a mounting groove 123 for mounting the atomizing core 20 is provided in the middle of the surface. The mounting groove 123 inner wall is provided with the arch to can sealing connection between messenger's mounting groove 123 and the atomizing core 20 surface, prevent that the tobacco tar from revealing. The mounting portion 1202 is mounted in the bowl-shaped structure of the bottom cover 30, and is in sealing connection with the bottom cover, so that the oil smoke leakage at the joint of the bottom cover and the bottom cover is avoided.

In addition, the mounting groove 123 is provided with a vent hole 124 communicating with the atomizing core 20. The mounting groove 123 and the vent hole 124 are arranged in a stepped structure, preferably, the mounting groove 123 is in a circular hole structure, and the diameter of the mounting groove 123 is larger than that of the vent hole 124, so that the stepped structure is formed. After the atomizing core 20 is installed, the bottom end of the atomizing core 20 contacts with the stepped surface of the stepped structure, so that the bottom of the installation groove 123 can block the atomizing core 20 from sliding out, and the installation stability of the atomizing core 20 can be ensured. More preferably, the mounting groove 123 is concentrically disposed with the vent hole 124.

The bottom cover 30 mentioned above is a bowl-shaped structure, and the mounting portion 1202 is disposed in the bowl-shaped structure of the bottom cover 30 and is in sealed connection with the mounting portion 1202 and the bowl-shaped structure, so that a cavity is formed between one end of the mounting portion 1202 and the bowl-shaped structure, and the cavity is the above-mentioned recycling cavity 15. The absorbent cotton 151 is disposed at the bottom of the recycling cavity 15, that is, at the bottom of the bowl-shaped structure, so that the smoke oil or the condensate flowing out from the atomizing core 20 is absorbed and stored by the absorbent cotton 151 and cannot flow out from the air inlet 32.

Also, as shown in fig. 2 and 3, another sealed cavity, referred to as air cavity 14, is formed between the mounting portion 1202 and the bowl of the bottom cap 30. The air chamber 14 communicates with the vent hole 124 of the sealing member 12 and also communicates with the air intake holes 32 of the bottom cover 30 as an air intake passage. In this embodiment, air cavity 14 and recovery chamber 15 intercommunication each other or air cavity 14 be for retrieving a part of chamber 15, and the design makes the oil absorption cotton 151 in retrieving the chamber 15 under the air current effect of air cavity 14, can take away the absorptive some tobacco tar of oil absorption cotton 151 like this, and then makes oil absorption cotton 151 can absorb more tobacco tar of leaking.

Preferably, as shown in fig. 2, 3 and 5, the recess structure at the lower end of the mounting portion 1202 is formed with a groove 126. The recess 126 forms the air chamber 14 with the bottom cover 30.
