-20. (canceled)
An electronic aerosol-generating device comprising:
- a heater configured to heat an aerosol-generating substance;
- a switching circuit configured to control supply of operating power to the heater;
- and
- a controller configured to, during a puff event, control the switching circuit to
- supply the operating power at a first power level in response to detecting a first level of airflow through the electronic aerosol-generating device, the first level of airflow being at or above a first threshold level,
- reduce the operating power from the first power level to a second power level after expiration of a first time period following detection of the first level of airflow, the second power level being a non-zero power level, and
- increase the operating power above the second power level in response to detecting an increase in airflow through the electronic aerosol-generating device above the first level of airflow.
A method of operating an electronic aerosol-generating device during a puff event, the electronic aerosol-generating device including a heater, a switching circuit and a controller, the method comprising:
- supplying operating power to the heater at a first power level in response to detecting a first level of airflow through the electronic aerosol-generating device, the first level of airflow being at or above a first threshold level;
- reducing the operating power from the first power level to a second power level after expiration of a first time period following detection of the first level of airflow, the second power level being a non-zero power level;
- and
- increasing the operating power above the second power level in response to detecting an increase in airflow through the electronic aerosol-generating device above the first level of airflow.
