Abstract: A vaporizer for vaporizing an aerosol-forming substrate includes: a vent tube having a first tube section and a second tube section in communication with the first tube section, the first tube section being adjacent to an air outlet of the vaporizer. An inner wall surface of the second tube section forms an expanding channel. The expanding channel gradually expands away from the first tube section.

Abstract: A vaporization assembly includes: a ferrule body having an inner cavity; a vaporization body adapted into the inner cavity and provided with a liquid inlet hole; and a blocking portion protruding from a cavity wall of the inner cavity and arranged to surround a periphery of the vaporization body, the blocking portion being provided with at least one liquid-through clearance. The ferrule body is movable in a preset direction relative to the vaporization body and has pre-loading and conduction positions. When the ferrule body is located at the pre-loading position, the blocking portion partitions the inner cavity into a liquid storage cavity and a mounting cavity in the preset direction, and the liquid inlet hole is located in the mounting cavity and isolated from the liquid storage cavity. Movement of the ferrule body from the pre-loading position to the conduction position reduces a volume of the mounting cavity.
