Aerosol-generating device with adjustable retention mechanism that enables precise control over aerosol release. The device features a housing with a cavity containing a heating element, and an adjustable retention element positioned adjacent to the cavity. The retention element defines a passage through which the aerosol-generating article passes during release. The retention element can be actuated from a receiving position to a retaining position, allowing the user to control the aerosol flow. The retention element's passage dimension is optimized for optimal aerosol flow during release, while the heating element provides controlled temperature conditions for the aerosol-forming substrate.
