Abstract
There is provided an aerosol generating system for heating a liquid aerosol-forming substrate. The system includes a liquid storage portion for storing the liquid aerosol-forming substrate, and a leakage preventer for preventing or reducing leakage of the liquid aerosol forming substrate from the liquid storage portion. The leakage preventer may include one or more of a porous plug at least partially located within the liquid storage portion, a first sealer between the liquid storage portion and a capillary wick, and a second sealer between the liquid storage portion and an electrical connector of an electric heater.
