Title:
AEROSOL GENERATING DEVICE AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/030411
Kind Code:
A1
Abstract:
An aerosol generating device and a control method thereof. The aerosol generating device comprises a battery cell (10) for providing a direct current; an inverter (21), comprising a switch circuit (211) and a resonant circuit (212), the resonant circuit (212) comprising an inductor (L) and a capacitor (C1), and the switch circuit (211) being configured to be alternately turned on and off under the driving of a pulse signal, so that the inductor (L), through which an alternating current flows, in the resonant circuit (212) generates a varying magnetic field; a susceptor (30), configured to be penetrated by the varying magnetic field to generate heat to heat a smokable material to generate an aerosol; and a controller (22), configured to adjust a duty cycle and/or a frequency of the pulse signal according to a real-time voltage of the battery cell (10). According to the above aerosol generating device, the duty ratio and/or frequency of the pulse signal of the driving switch circuit (211) are adjusted by means of the real-time voltage of the battery cell (10), thereby avoiding the problems that a pre-heating speed of a heating device is inconsistent and the smoking experience of a user is affected due to a decrease of the voltage of the battery cell (10).
