[0041] The atomizer housing 13 is also provided with a first plugging hole 132 connected to the first oil storage space 131. The open end of the inner cylinder 121 is detachably plugged into the first plugging hole 132, and the second oil storage space 1211 is connected to the first oil storage space 131. It can be understood that when the open end of the inner cylinder 121 is not plugged into the first plugging hole 132, the first plugging hole 132 can be sealed with a rubber plug, so that the smoke oil in the first oil storage space 131 will not leak through the first plugging hole 132.

[0042] In the present invention, the atomizer housing 13 is also provided with a first plugging hole 132 connected to the first oil storage space 131, and the open end of the inner cylinder 121 can be removably plugged into the first plugging hole 132; when the open end of the inner cylinder 121 is not plugged into the first plugging hole 132, the first plugging hole 132 can be sealed with a rubber plug, so that the oil replenishing assembly 12 and the atomizer assembly 11 can be sold separately, and it is convenient for users to replace the oil replenishing assembly 12 in time. When the open end of the inner cylinder 121 is not plugged into the first plugging hole 132, the oil in the second oil storage space 1211 of the oil replenishing assembly 12 and the annular space 1221 can be replenished into the first oil storage space 131, so that more oil is stored in the oil replenishing atomizer 1.
