Abstract
An electronic smoke apparatus comprising an inhale sensor, a smoke source containing vapor-able smoke flavored substances, an electric heater for heating up the smoke flavored substances, and a power management controller to control power supply to operate the heater; wherein the power management controller is to adaptively supply operating power to the heater according to characteristics of a smoking inhaling event detected at said inhale sensor.
Claims24
A power management device for an electronic aerosol-generating device, the power management device comprising:
- a switching circuit configured to control supply of operating power to a heater to generate an aerosol;
- and
- a controller configured to control the switching circuit,
- wherein, during a puff event, the controller is configured to control the switching circuit to
- supply the operating power at a first power level in response to detecting airflow through the electronic aerosol-generating device 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 airflow at or above the first threshold level, the second power level less than the first power level, and
- increase the operating power from the second power level to a third power level after expiration of a second time period and in response to detecting airflow through the electronic aerosol-generating device at or above a second threshold level;
- wherein the expiration of the second time period is after the expiration of the first time period;
- and
- wherein the third power level is less than or equal to the first power level.
