Abstract
A cartridge assembly for an aerosol-generating system including a housing having an air outlet and an air inlet upstream of the housing air outlet; and a cartridge disposed within the housing. The cartridge includes a fluid-permeable heating element within a cartridge body; a cartridge air inlet; a cartridge air outlet; and an airflow path extending from the cartridge air inlet to the cartridge air outlet, via the fluid-permeable heating element. At least a portion of the cartridge may move between a first position, in which air from the housing air inlet is blocked from flowing to the housing air outlet, via the cartridge air inlet, the fluid-permeable heating element, and the cartridge air outlet; and a second position, in which an unrestricted airflow path exists from the housing air inlet to the housing air outlet, via the cartridge air inlet, the fluid-permeable heating element, and the cartridge air outlet.
