Abstract

A control method for an aerosol-generating device, including: detecting whether an aerosol-generating device is in a suction state (S110); detecting a child-lock state of the aerosol generating device (S120); determining whether the number of suctions of the aerosol generating device within a first preset time period is greater than a first threshold (S130); enabling the aerosol generating device to be in a child-lock closed state (S140); determining whether the single atomization time of the aerosol generating device is greater than a second time threshold (S150); and the aerosol generating device stopping atomization (S160).
