Abstract
A vaporizing assembly for an aerosol generating system includes a sheet heating element and a delivery device configured to deliver a liquid aerosol-forming substrate from a liquid storing portion to the sheet heating element. The sheet heating element is spaced apart from the delivery device and is configured to heat the delivered liquid aerosol forming substrate.
Claims12
A vaporizing assembly for an aerosol generating system, the vaporizing assembly comprising:
- a heating element at a first position in the vaporizing assembly, the heating element including,
- a sheet heating element including,
- a plurality of electrically conductive fibers;
- a liquid storing portion at a second position in the vaporizing assembly, the first position being longitudinally separated from the first position, the liquid storing portion configured to store a liquid aerosol forming substrate therein;
- and
- a delivery device configured to deliver the liquid aerosol forming substrate from the liquid storing portion to the heating element, the delivery device between the liquid storing portion and the heating element, the delivery device and the heating element defining an air gap therebetween, the delivery device including,
- a micropump configured to pump the liquid aerosol forming substrate from the liquid storing portion to the heating element, and the heating element configured to heat the delivered liquid aerosol forming substrate.
