An aerosol generating system with provention of condensate leakage

摘要

There is provided an aerosol generating system for heating a liquid aerosol-forming substrate. The system comprises: an aerosol-forming chamber (127); and leakage prevention means (305,307) configured to prevent or reduce leakage of liquid aerosol condensate from the aerosol generating system. The leakage prevention means may comprise 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.
