It may be understood that, to better seal the accommodating cavity 11, a seal member may also be arranged between the periphery of the bottom wall 24 of the vaporization base 2 and the inner wall surface of the housing 1.
A shape of a cross section of the annular side wall 26 of the vaporization base 2 is not limited; and preferably, the first side wall 21 is of a plane structure, for ease of assembly of the vaporization core 3 of a flat plate structure. In this embodiment, as shown in FIG. 6 , the annular side wall 26 of the vaporization base 2 includes the first side wall 21 and a second side wall 22 and a third side wall 23 arranged on two opposite sides of the first side wall 21, and the second side wall 22 and the third side wall 23 are parallel to each other and connected to two sides of the first side wall 21 respectively.

In addition, compared with the case that the vaporization surface 31 is disposed protruding out of the inner surface of the first side wall 21, the vaporization surface 31 may alternatively be flush with the inner surface of the first side wall 21 of the vaporization base 2 to prevent the vaporization core 3 from blocking the airflow in the vaporization cavity 20, so that the airflow can smoothly flow through the vaporization cavity 20, and the vaporization efficiency of the vaporizer 100 is higher.
