Abstract

An aerosol-generating device includes: a heater configured to heat an aerosol-generating substance; a battery configured to supply power to the heater; an air flow detection sensor configured to detect an air flow change inside the aerosol-generating device; a pressure sensor configured to detect a pressure change outside the aerosol-generating device; and a controller, where the controller may determine whether suction has occurred based on a first sensing value received from the airflow detection sensor and a second sensing value received from the pressure sensor.

Description

technical field [0001] The present disclosure relates to aerosol generating devices and methods of operation thereof. Background technique [0002] In recent years, the demand for alternatives to traditional cigarettes has been increasing. For example, instead of smoking combustible cigarettes, many people use an aerosol-generating device that generates an aerosol by heating an aerosol-generating substance. [0003] The puff detection sensor of the aerosol generating device detects the pressure change, and the controller controls the heater based on the pressure change. On the other hand, when the pressure outside the aerosol generating device changes rapidly, the puff detection sensor can also detect the change in pressure. In this case, the controller may erroneously determine that puffing has occurred, even though puffing has not actually occurred. SUMMARY OF THE INVENTION [0004] technical problem [0005] One or more embodiments provide an aerosol generating devi...
