Abstract
An electrically heated smoking system for receiving an aerosol forming substrate includes a heater for heating the substrate to form the aerosol. The heater includes a heating element. The electrically heated smoking system and the heating element are arranged such that, when the aerosol forming substrate is received in the electrically heated smoking system, the heating element extends a distance only partially along the length of the aerosol forming-substrate, and the heating element is positioned towards the downstream end of the aerosol forming substrate.
Claims10
An electrically heated smoking system comprising:
- a housing;
- an aerosol forming substrate;
- and
- a heater configured to heat the aerosol forming substrate and form an aerosol, the heater including,
- at least a first heating element arranged at a downstream end of the aerosol forming substrate and extending a first distance partially along a length of the aerosol forming substrate, the length of the aerosol forming substrate extending from the downstream end of the aerosol forming substrate to an upstream end of the aerosol forming substrate, a downstream end of the first heating element and the downstream end of the aerosol forming substrate being spaced apart, an upstream end of the first heating element and the upstream end of the aerosol forming substrate being spaced apart, wherein the upstream end of the first heating element is inside the aerosol forming substrate.
