Heating element, heat-not-burn device, and heating control method therefor

Abstract

A heating control method for a heat-not-burn device that includes a heating element for heating an aerosol-forming substrate includes: controlling the heating element so as to increase from an initial temperature to a first temperature when heating is started, and maintaining the first temperature; controlling the heating element so as to increase from a current temperature to a second temperature when detecting a puffing action, the second temperature being greater than the first temperature; and controlling the heating element so as to decrease from a current temperature to a third temperature when detecting that the puffing action ends, the third temperature being less than the second temperature.
