Japanese Patent JP7256738
Kind Code:
B2
Abstract:
An electrically operated aerosol-generating system comprising a heating element, a power supply, and electric circuitry (109) connected to the heating element and to the power supply and comprising a memory, the electric circuitry being configured to: measure an initial electrical resistance of the heating element; measure a subsequent electrical resistance of the heating element after the measurement of the initial electrical resistance and between user puffs on the system; determine the difference between the initial electrical resistance and the subsequent electrical resistance; compare the difference to a cooling threshold; and when the difference is above the cooling threshold, prevent or limit the supply of power to the heating element until the difference falls below the cooling threshold.
