Abstract
An aerosol-generating system may include a liquid storage portion configured to hold aerosol-forming substrate, a vaporizer, and a pump. The liquid storage portion includes a movable wall and an outlet. The vaporizer includes a heating element having a structure that at least partially defines an internal passage. The pump may deliver liquid aerosol-forming substrate from the outlet of the liquid storage portion to the internal passage of the heating element. The pump may include a micro stepper motor with a drive shaft that is configured to rotate a particular amount based on performing an individual step, a piston connected to the movable wall, and a lead screw connecting the drive shaft to the piston and configured to translate rotation of the drive shaft into axial movement of the piston and the movable wall. The vaporizer may at least partially vaporize the delivered liquid aerosol-forming substrate.
