Abstract
A method for controlling temperature of a heating element in an electronic inhaler for vaporizing an aerosol forming substrate. The method includes, in a first stage, applying power to and increasing a temperature of the heating element from an initial temperature to a first temperature; in a second stage, controlling power to decrease the temperature of the heating element from the first temperature to a second temperature; and in a third stage, controlling the heating element to provide a constant temperature operation at the second temperature. During detection of inhalation, power to the heating element is increased to raise its temperature to a third temperature. In the third stage, the heating element increases the temperature only when suction is detected, thereby ensuring that a supply of an aerosol to the inhaler and minimize waste of electric energy and the aerosol forming substrate.
