    Abstract: An electrically operated aerosol-generating system may include a reservoir configured to hold a liquid aerosol-forming substrate, an atomizer assembly configured to vaporize the liquid aerosol-forming substrate to form an aerosol, and a pump configured to convey the liquid aerosol-forming substrate from the reservoir to the atomizer assembly. The reservoir may include a substantially rigid housing and an inlet valve that is configured to allow air into the reservoir based on a pressure difference between an interior of the housing and an exterior of the housing exceeding a threshold pressure difference. This improves the reliability and efficiency of delivery of liquid to the wick. The system may further include a robust reservoir that is configured to at least partially mitigate liquid leakage between the reservoir interior and the reservoir exterior.

    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.
