Abstract (en)

[origin: EP4218441A1] This application provides an aerosol generation device, configured to heat an aerosol-forming article to generate an aerosol for inhalation, the device including a housing, where the housing is internally provided with: a cavity; at least one heater, configured to heat the aerosol-forming article; and a support mechanism, constructed to surround at least a part of the cavity, where an inner surface of the support mechanism is provided with a plurality of first protrusions and a plurality of second protrusions spaced along a circumferential direction to clamp the aerosol-forming article received in the cavity; and the plurality of first protrusions and the plurality of second protrusions are arranged sequentially along an axial direction of the support mechanism. The above aerosol generation device simultaneously clamps the aerosol-forming article at different heights through double-layer protrusions inside, so that the aerosol-forming article can be stably received in the aerosol generation device, and then stably transfer heat with a heater.
