The atomizer 10 further comprises a seal 3, the seal 3 being arranged between the mounting base 1 and the atomizing core 2. Wherein the sealing element 3 may be a sealing ring. The porous substrate 21 is any one of porous ceramics and porous metals.
The porous substrate 21 communicates with the liquid stored in the liquid reservoir 4 and adsorbs the liquid from the liquid reservoir 4 by capillary force, and the heating element 22 is used to heat the liquid atomizing the porous substrate 21. In one embodiment, the porous substrate 21 includes an oil transfer portion 211 and a protrusion portion 212 integrally formed on one side of the oil transfer portion 211, and the liquid leakage buffer structure 122 is in contact with a peripheral edge of a surface of the oil transfer portion 211 on which the protrusion portion 212 is provided.

It will be appreciated that the sub-leak buffer 1221 may not be used to support the atomizing core 2 if the atomizing core 2 is secured by other components. When the pressure of the liquid storage bin 4 is larger than that of the atomizing cavity 125, the sub-liquid leakage buffer member 1221 can collect the tobacco tar leaked from the porous substrate 21, and when the pressure of the liquid storage bin 4 is smaller than that of the atomizing cavity 125, the tobacco tar stored in the sub-liquid leakage buffer member 1221 can flow back to the porous substrate 21 contacted with the sub-liquid leakage buffer member 1221, so that the effective utilization of leaked oil is realized, and the multi-cycle collection and backflow of the tobacco tar can be realized by the liquid leakage buffer structure 122.
