The first seal ring is installed between the outer electrode 131 and the bottom wall of the first counterbore portion 1221 to achieve 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, and when the outer electrode 131 is mounted on the first connecting member 12, the sealing performance between the two is poor. When the component is in operation, air may enter the air inlet in 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. Moreover, when the air enters the air inlet in the atomizing core 13 from between the outer electrode 131 and the first connecting member 12, the battery assembly is corroded, and the smoke oil in the soot bottle 2 is from the outer electrode 131 and the first A gap between the connectors 12 enters the battery assembly, which also causes corrosion of the battery assembly, thereby affecting the normal use of the atomizing assembly. In the embodiment, the structure of the first sealing member 3 ensures that the airflow passage in the atomizer 1 is smoothly ventilated, and the air or the smoke oil is prevented from corroding the battery assembly, thereby effectively avoiding affecting the normal use of the atomizing assembly.

As shown in FIG. 4, the second sealing member 4 is for sealing the mouth of the soot bottle 2, and the second sealing member 4 is an annular second sealing ring which has good elasticity and sealing performance. The second sealing ring is disposed on the outer wall of the atomizing core 13, the inner circumferential surface of the second sealing ring is abutted on the blocking portion 1312, and the two end faces of the second sealing ring are respectively connected with the first connecting member 12 and the second connecting member The pieces 14 are mutually abutted to achieve a seal between the air inlet in the atomizing core 13 and the mouth of the soot bottle 2, that is, to seal between the first through hole 1311 and the mouth of the connecting portion 22, thereby It is possible to effectively prevent the oil in the oil bottle 2 from clogging the air inlet in the atomizing core 13, thereby ensuring the normal use of the atomizing assembly. Furthermore, when the atomizing core 13 is inserted into the soot bottle 2, it is possible to prevent the smoke oil from overflowing upward.

The use of the atomizing assembly described in the above embodiments has the following beneficial effects:
