Abstract
Provided is a heater for an aerosol-generating device including a first electrically conductive pattern configured to perform heating and a second electrically conductive pattern arranged in parallel with the first electrically conductive pattern. The first electrically conductive pattern and/or the second electrically conductive pattern may include a material having a relatively small resistance temperature coefficient. Accordingly, a temperature increase rate of the heater may be greatly improved.
Claims11
A heater comprising:
- a first electrically conductive pattern configured to perform heating;
- and
- a second electrically conductive pattern disposed in parallel with the first electrically conductive pattern,
- wherein the first electrically conductive pattern includes a material having a temperature coefficient of resistance that is less than or equal to 1,000 ppm/° C.
- wherein the second electrically conductive pattern is disposed outside of the first electrically conductive pattern, and
- wherein a resistance of the second electrically conductive pattern is less than or equal to a resistance of the first electrically conductive pattern.
An aerosol generating device comprising:
- a housing forming an accommodating space in which an aerosol-generating article is accommodated;
- and
- a heater configured to heat the aerosol-generating article accommodated in the accommodating space,
- wherein the heater comprises:
- a first electrically conductive pattern including a material having a temperature coefficient of resistance less than or equal to 1,000 ppm/° C.;
- and
- a second electrically conductive pattern disposed in parallel with the first electrically conductive pattern,
- wherein the second electrically conductive pattern is disposed outside of the first electrically conductive pattern, and
- wherein a resistance of the second electrically conductive pattern is less than or equal to a resistance of the first electrically conductive pattern.
