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. A device comprising:
a battery configured to supply power;
a heater configured to heat a replaceable aerosol generating material;
a sensor;
at least one output unit; and
a controller configured to detect a user's puff by using the sensor, determine, before the user's puff, an initial number of available puffs based on power of the battery, modify, after the user's puff, the initial number of available puffs by subtracting a number of the detected user's puff from the initial number of available puffs to determine a modified number of available puffs, adjust the modified number of available puffs based on puff characteristic data of the detected user's puff to determine an adjusted number of available puffs, and control the at least one output unit based on the adjusted number of available puffs,
wherein the controller control the at least one output unit to output a notification of a need for charging when the adjusted number of available puffs is zero.
2. The 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 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 device of claim 1 , wherein the controller adjusts the modified number of available puffs based further on a puff interval of the detected user's puff.
5. The device of claim 1 , wherein the controller outputs the adjusted number of available puffs by using the at least one output unit.
6. The device of claim 1 , wherein
the output unit comprises a vibration motor, and
the controller controls an output strength of the vibration motor based on the adjusted number of available puffs.
7. The device of claim 1 , wherein
the output unit comprises a Light Emitting Diode (LED) lamp, and
the controller controls an emission intensity or a flickering interval of the LED lamp based on the adjusted number of available puffs.
8. The device of claim 1 , wherein
the output unit comprises a speaker, and
the controller controls a sound output intensity of the speaker or a type of sound output by the speaker based on the adjusted number of available puffs.
9. The device of claim 1 , further comprising an external casing,
wherein the controller controls a temperature of the external casing based on a heater temperature at a time of the user's puff.
10. The device of claim 1 , wherein the controller determines the adjusted number of available puffs based further on an estimated remaining battery power.
11. The device of claim 1 , wherein the controller controls the at least one output unit to provide a notification to a user when temperature of the heater is equal to or higher than a predetermined temperature.
12. The device of claim 1 , wherein the controller controls the at least one output unit to provide a notification to a user based on the puff strength or a puff interval of the user's puff.
13. The device of claim 1 , wherein the controller controls the at least one output unit to provide a notification to a user, at a predetermined interval, that puffing is available.
