- the controller may first reset the temperature sensor and then sequentially reset the puff sensor.
- the controller may reset the puff sensor for detecting the puffs by the user.
- the controller may determine whether or not the reset of the puff sensor is successful.
- the controller may control an output unit to display a notification of the reset failure.
- the controller may control the output unit to output visual information or voice information indicating that the reset of the puff sensor has failed.
- the controller may reset the temperature sensor for detecting the temperature of the heater.
- the controller may determine whether or not the reset of the temperature sensor is successful.
- the controller may control the output unit to display a notification of the reset failure.
- the controller may control the output unit to output visual information or voice information indicating that the reset of the temperature sensor has failed.
- FIG. 14 is a flowchart illustrating another example of a method of controlling an aerosol generating device, according to some embodiments.
- Operation S1410 is an operation in which a controller determines whether or not a cigarette insertion hole is opened.
- the controller may determine whether or not the cigarette insertion hole is opened, on the basis of a sensing signal from an opening/closing detection sensor.
- the controller may set an operation mode of an aerosol generating device to an ON mode or an OFF mode.
- the controller may set the operation mode of the aerosol generating device to the ON mode.
- the controller may set the operation mode of the aerosol generating device to the OFF mode.
- the controller may determine whether or not a heater is in a heating state (i.e., activated). The controller may determine whether or not the heater is in the heating state by detecting whether or not power is supplied from a battery to the heater. When the heater is in a heating release state (i.e., deactivated), in operation S1460, the controller may reset an insertion detection sensor and a temperature sensor. When the heater is in the heating release state, resetting the temperature sensor for detecting a temperature of the heater may not affect a normal operation of the aerosol generating device. As described above, operation S1450 may be omitted according to an embodiment.
- the controller may reset the insertion detection sensor and the temperature sensor.
- the resetting of the insertion detection sensor and the temperature sensor may be sequentially performed.
- the controller may first reset the insertion detection sensor and sequentially reset the temperature sensor.
- the controller may first reset the temperature sensor and sequentially reset the insertion detection sensor.
- the controller may determine whether or not the event of detecting insertion of the cigarette into the aerosol generating device by the insertion detection sensor occurs.
- the controller may reset the insertion detection sensor and the temperature sensor.
- the controller may reset the insertion detection sensor and the temperature sensor when the insertion detection sensor does not detect the insertion of the cigarette for a predetermined period of time.
- the controller may count, by using an RTC, a period during which the event of detecting insertion of the cigarette by the insertion detection sensor does not occur.
- the controller may control the heater in a heating state.
- the controller may control the heater in the heating state. For example, the controller may control the heater to start a heating operation according to a predetermined temperature profile.

Abstract
Un dispositif de génération d'aérosol comprend un dispositif de chauffage conçu pour chauffer la cigarette insérée, un capteur de température conçu pour détecter une température du dispositif de chauffage, un capteur de détection d'insertion conçu pour détecter l'insertion de la cigarette, un capteur de bouffée conçu pour détecter des bouffées d'un utilisateur, et un dispositif de commande conçu pour réinitialiser le capteur de température et/ou le capteur de bouffée en réponse à un signal de détection émis par le capteur de détection d'insertion.
