Abstract: A method of generating an aerosol in an aerosol-generating system includes storing liquid aerosol-forming substrate in a liquid storage portion and delivering via a pump a liquid aerosol-forming substrate from the liquid storage portion to an atomizer. The method also includes sensing a puff via a a puff sensor in an airflow path of the aerosol-generating system and determining a puff intensity during the puff via a controller. The delivery flow rate of the liquid aerosol-forming substrate to the atomizer is adjusted in response to the determined puff intensity.

Abstract: An aerosol-generating system may include a liquid storage portion configured to hold liquid aerosol-forming substrate, a vaporizer including a heating element with an internal passage at least partially defined by a surface of the heating element, and a micro pump configured to deliver liquid aerosol-forming substrate from the liquid storage portion to the internal passage of the heating element, such that the vaporizer is configured to heat the delivered liquid aerosol-forming substrate at the internal passage to a temperature sufficient to volatilize at least a part of the delivered liquid aerosol-forming substrate. The micro pump may be configured to deliver a particular amount of liquid aerosol-forming substrate to the internal passage based on the micro pump performing an individual pump cycle.
