Heated aerosol-generating device and method for generating aerosol with consistent properties

摘要

There is provided a method of controlling aerosol production in an aerosol-generating device, the device including: a heater including at least one heating element configured to heat an aerosol-forming substrate; and a power source for providing power to the heating element, including the steps of: controlling the power provided to the heating element such that in a first phase power is provided such that the temperature of the heating element increases from an initial temperature to a first temperature, in a second phase power is provided such that the temperature of the heating element drops below the first temperature, and in a third phase power is provided such that the temperature of the heating element increases again. Increasing the temperature of the heating element during a final phase of the heating process reduces or prevents the reduction in aerosol delivery over time.

1. A method of controlling aerosol production in an aerosol-generating device,
the device comprising:
a heater comprising at least one heating element configured to heat an aerosol-forming substrate; anda power source configured to provide power to the at least one heating element, the method comprising:
providing power to the at least one heating element; andcontrolling the power provided to the at least one heating element such that
in a first phase, the power is provided to the at least one heating element such that a temperature of the at least one heating element increases from an initial temperature to a first temperature,in a second phase, the power is provided to the at least one heating element such that the temperature of the at least one heating element reduces and is maintained at a second temperature, the second temperature being lower than the first temperature, andin a third phase, the power is provided to the at least one heating element such that the temperature of the at least one heating element increases to a third temperature,wherein the aerosol-forming substrate is heated during each of the first phase, the second phase, and the third phase.
