The method comprises: in response to a vaping trigger signal, controlling a heating assembly to raise the temperature to a target temperature range, and controlling an atomization matrix to move, by a first target length, to a region to be heated, wherein the atomization matrix in said region is atomized within the target temperature range and forms vapor; and after a preset condition is met, controlling the heating assembly to be cooled to a temperature below the target temperature range, and controlling the atomization matrix to continue to move, by a second target length, to said region, wherein the first target length and the second target length are both approximately equal to the length of said region. The method can prevent a heating assembly from roasting an atomization matrix in the same area region for a long time, thereby avoiding a burnt smell during vaping; moreover, after the vaping is completed, the heat of the atomization matrix can be preserved by means of the residual heat of the heating assembly, thereby shortening a heating and roasting time during the next instance of vaping, and increasing a vapor generation speed.
