Abstract

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.

First claim

What is claimed is:

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 the 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 when the remaining number of available puffs is equal to or greater than the predetermined threshold, and
change the first output mode to a second output mode when the remaining number of available puffs is less than the predetermined threshold.

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 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 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 when the number of the remaining number of available puffs is less than the threshold value.

7 . 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.

8 . The aerosol generating device of claim 7 ,
at least one of a intensity and interval of a visual output means and the tactile output means is adjusted according to the number of available puffs.

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 when the number of available puffs remaining is 0.
