Abstract: There is provided an aerosol generating device for heating an aerosol-forming substrate, including a storage portion for storing the aerosol-forming substrate and a vaporizer for heating the aerosol-forming substrate to form an aerosol. The storage portion has an outer housing and an internal passageway, the storage portion forming a reservoir for the aerosol-forming substrate between the outer housing and the internal passageway, and the vaporizer extends at least partially inside the internal passageway in the storage portion. The device further includes a porous interface at least partially lining the internal passageway for conveying the aerosol-forming substrate from the storage portion towards the vaporizer.

Abstract: There is provided an aerosol generating system for heating a liquid aerosol-forming substrate. The system includes an aerosol-forming chamber, and a leakage preventer for preventing or reducing leakage of liquid aerosol condensate from the aerosol generating system. The leakage preventer may include one or more of: at least one cavity in a wall of the aerosol-forming chamber, for collecting droplets of condensed liquid aerosol-forming substrate; at least one hooked member for collecting droplets of condensed liquid aerosol-forming substrate; an impactor for disrupting airflow in the aerosol-forming chamber so as to collect liquid droplets; and a closure member for substantially sealing the aerosol-forming chamber when the aerosol generating system is not in use.
