Abstract
An aerosol-generating system including a cartridge is provided, the cartridge including a liquid storage portion including a housing configured to hold a liquid aerosol-forming substrate, the housing having an opening; and a heater assembly including at least one heater element fixed to the housing and extending across an opening of the housing, wherein a width of the at least one heater element of the heater assembly is smaller than a width of the opening of the housing. The heater element may be spaced from a periphery of the opening, leading to more efficient heating and aerosol production.
Claims1
An aerosol-generating system, comprising:
- an aerosol-generating device comprising a power source;
- and
- a cartridge removably coupled to the aerosol-generating device, the cartridge comprising:
- a liquid storage portion comprising a housing having an open end and containing a liquid aerosol-forming substrate,
- a substantially flat heater assembly at the open end of the housing and comprising an electrical heating element configured to heat the liquid aerosol-forming substrate to form an aerosol, the electrical heating element being both substantially flat and arranged in a curved manner,
- a capillary material disposed in contact with the electrical heating element and comprising a ceramic or a ceramic-based material, the capillary material being configured to convey the liquid aerosol-forming substrate to the electrical heating element, and
- a plurality of air inlets and an air outlet,
- wherein the liquid storage portion is disposed at a first side of the heater assembly and an airflow channel is disposed at a second side of the heater assembly, the airflow channel defining an airflow path over the heater assembly and configured to convey the aerosol, and
- wherein the power source of the aerosol-generating device is configured to supply power to the substantially flat heater assembly.
