DETECTION OF AEROSOL-FORMING SUBSTRATE IN AEROSOL GENERATING DEVICE Russian patent published in 2017 - IPC A24F47/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to aerosol-generating device, which comprises a heating element, configured to heat an aerosol-forming substrate; a power source connected to heating element; and a controller connected to heating element and to power source, wherein controller is configured to control power supplied to heating element from power source, in order to maintain temperature of heating element at a target temperature, and is configured to compare a measure of power supplied to heating element or energy supplied to heating element from power source, to a threshold measure of power or energy to detect presence of an aerosol-forming substrate close to heating element or a material property of an aerosol-forming substrate close to heating element.

EFFECT: technical result consists in preventing activation of heating element, when substrate is absent.
