An aerosol-generating system comprising: an air inlet (18) and an air outlet (24); a liquid storage portion (30) holding a liquid aerosol-forming substrate, the liquid storage portion (30) having a liquid outlet; an air flow passage (22) from the air inlet (18) to the air outlet (24) past the liquid outlet, wherein the air flow passage (22) is shaped so that there is a pressure drop within the air flow passage (22) at the liquid outlet when air flows from the air inlet (18) to the air outlet (24) through the air flow passage (22); and a heating element (26) within the flow path, positioned between the liquid outlet and the air outlet (24). The system is advantageously configured so that when air flows from the air inlet (18) to the air outlet (24) through the air flow passage, the pressure at the liquid outlet is lower than the pressure within the liquid storage portion (30). This draws liquid out of the liquid storage portion (30) into the airflow, which delivers it to the heating element (26) for vapourisation. |
