AEROSOL-GENERATING APPARATUS WITH FEEDBACK CONTROL Russian patent published in 2022 - IPC A24F47/00 

FIELD: electrical engineering.

SUBSTANCE: group of inventions relates to an aerosol-generating apparatus, an aerosol-generating system, and a method for changing a property of an aerosol. The aerosol-generating apparatus comprises a heating element configured to heat the aerosol-forming substrate in order to generate an aerosol, a temperature sensor for measuring the temperature of the heating element, an aerosol monitoring tool for measuring a property of the aerosol, including at least one of a physical property and the chemical composition of the generated aerosol, and a controller configured to adjust the power supplied to the heating element, based on: i) the measured temperature of the heating element in the first feedback control circuit; and ii) the measured aerosol property in the second feedback control circuit. The apparatus comprises an auxiliary aerosol monitoring tool for adjusting the aerosol properties of the generated aerosol. The controller is configured to adjust at least one control variable for the auxiliary aerosol monitoring tool based on the measured properties of the aerosol in the second feedback control circuit.

EFFECT: improved heater control mechanism is provided.
