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.
Claims6
An electronic vaping device comprising:
- a reservoir configured to hold a liquid;
- a heater configured to heat liquid drawn from the reservoir;
- a switching circuit configured to control supply of operating power to the heater;
- and
- a controller configured to 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 vaping 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,
- reduce the operating power from the second power level to zero in response to detecting a second level of airflow through the electronic vaping device,
- increase the operating power from zero to the first power level in response to detecting a third level of airflow through the electronic vaping device, the third level of airflow being at or above the first threshold level, and
- reduce the operating power from the first power level to the second power level after expiration of a second time period following detection of the third level of airflow, the second time period being less than the first time period.
