Aerosol generating device and method for providing adaptive feedback through puff recognition
Provided is a device including: a battery configured to supply power; a heater configured to heat an aerosol generating material by receiving power from the battery; a sensor; at least one output unit; and a controller, wherein the controller detects a user's puff by using the sensor and controls at least one output unit based on puff characteristic data based on a result of the detection.
1 . An aerosol generating device comprising:
a heater configured to heat an aerosol generating material;
a sensor configured to detect a user's puff;
an output unit configured to provide feedback on the user's puff, and
a controller configured to:
determine a remaining number of available puffs based on a detection result of the sensor,
compare the remaining number of available puffs with a predetermined threshold,
maintain a first output mode of the output unit based on determining the remaining number of available puffs is equal to or greater than the predetermined threshold, wherein a first output notification is provided to the user in the first output mode, and
change the first output mode to a second output mode based on determining the remaining number of available puffs is less than the predetermined threshold, wherein a second output notification different from the first output notification is provided to the user in the second output mode.
2 . The aerosol generating device of claim 1 , wherein
the sensor comprises a temperature sensor configured to measure a temperature of the heater, and
the controller detects the user's puff based on a variation in the temperature of the heater by using the temperature sensor.
3 . The aerosol generating device of claim 1 , wherein
the sensor comprises a flux sensor, and
the controller detects the user's puff based on a variation in flux in the device by using the flux sensor.
4 . The aerosol generating device of claim 1 , wherein
the first output mode outputs, as the first output notification, the number of the remaining number of available puffs through a visual output means including an LED display or an LED lamp in order to provide feedback on the user's puff.
5 . The aerosol generating device of claim 4 , wherein
the second output mode, as the second output notification, provides feedback on the user's puff through a tactile output means including a vibration motor.
6 . The aerosol generating device of claim 1 , wherein
the controller provides feedback on the user's puff through a visual output means including an LED display or an LED lamp and a tactile output means including a vibration motor based on determining the number of the remaining number of available puffs is less than the threshold value.
7 . The aerosol generating device of claim 6 ,
wherein at least one of an intensity or an interval of the visual output means and the tactile output means is set differently between the first output mode and the second output mode.
8 . The aerosol generating device of claim 1 , wherein
the controller determines the number of available puffs based on the detection result of the sensor, power of the battery or an amount of an aerosol generating material.
9 . The aerosol generating device of claim 1 , wherein
the controller stops the operation of a visual output means including an LED lamp and a tactile output means including a vibration motor based on determining the number of available puffs remaining is 0.
