The embodiments of the present application relate to the technical field of electronic atomization. Disclosed are a control method and an aerosol generation apparatus. The control method comprises: during a first time phase of vaping, controlling a power source to supply energy to a heater, such that the temperature of the heater is at or below a first temperature; and during a second time phase of vaping, controlling the power source to intermittently supply energy to the heater multiple times, such that a maximum temperature reached after energy supply exceeds the first temperature. By means of the method, the temperature of the heater fluctuates in a waveform during the second time phase, the maximum temperature of the heater exceeding the first temperature. Thus, stable aerosol can be generated during vaping, thereby being conducive to maintaining a good mouthfeel of the aerosol; moreover, intermittent energy supply aligns with intermittent vaping habits of users, thereby preventing aerosol waste caused by continuous high-temperature baking of an aerosol-forming matrix.

Embodiments of the present application relate to the technical field of electronic atomization, and disclosed are a control method and an aerosol generating device. On the basis of energy demand characteristics in the baking process of an aerosol-forming substrate, the entire baking process is divided into multiple time periods, and corresponding energy supply is set for each period, such that the aerosol-forming substrate receives heat output by a heater in time periods, and the aerosol generated after baking can rapidly reach an inhalable state and maintain the inhalable state. In addition, on the basis of heat conduction characteristics, for each first time period, energy is continuously supplied in a first time interval and the supply of energy is stopped in a second time interval, such that the temperature first rises to the highest temperature and then falls to the lowest temperature within the first time period, and a temperature difference between the highest temperature and the lowest temperature is above 15 °C, and thus, the heat provided by the heater can be absorbed in a relatively large proportion by the aerosol-forming substrate when energy is supplied in the next time period. Therefore, the effects of improving the energy utilization efficiency and reducing the energy consumption are achieved.
