The first seal ring is mounted between the outer electrode 131 and the bottom wall of the first counter-bore portion 1221 to effect a seal therebetween. Since the outer electrode 131 is made of a conductive metal material, the first connecting member 12 is usually made of a hard material, when the outer electrode 131 is mounted on the first connecting member 12, the sealing performance between the two is poor, and when the atomizing assembly works, air may enter the air inlet of the atomizing core 13 from between the outer electrode 131 and the first connecting member 12, thereby affecting the air intake effect of the atomizer 1. Furthermore, when air enters the air inlet of the atomizing core 13 from the space between the outer electrode 131 and the first connecting member 12, the battery assembly is corroded, and the smoke in the smoke bottle 2 enters the battery assembly from the space between the outer electrode 131 and the first connecting member 12, the battery assembly is also corroded, so that the normal use of the atomizing assembly is affected.

Moreover, when the atomizing core 13 is inserted into the tobacco tar bottle 2, the tobacco tar can be prevented from overflowing upwards.

The atomization assembly in the embodiment has the following beneficial effects:
