Aerosol generating device and method for providing adaptive feedback through puff recognition

1. An aerosol generating device comprising:

a holder that includes a cigarette insertion hole configured to receive a cigarette, and is configured to generate an aerosol by heating an aerosol generating material included in the cigarette inserted into the cigarette insertion hole; and

a cradle including an inner space into which the holder is inserted,

wherein the holder further comprises:

a heater for heating the aerosol generating material;

a battery for supplying power to the heater;

a sensor for detecting a user's puff;

at least two output units including a light emitting diode (LED) lamp and a vibration motor; and

a controller for controlling the aerosol generating device,

wherein at least one of the holder and the cradle includes at least one attaching member configured to increase attachment strength between the holder and the cradle by using a magnetic force,

the cradle includes a terminal for supplying power to the holder inserted into the inner space of the cradle,

the inner space is formed on one side of the cradle so that when the holder is inserted into the inner space of the cradle, the holder is capable of tilting between a first position where the cigarette insertion hole is completely concealed by the cradle and a second position where the cigarette insertion hole of the holder is completely exposed out of the cradle,

the holder is to be coupled with the cradle by the attaching member even at the second position where the cigarette insertion hole of the holder is completely exposed out of the cradle, so that power is supplied from the terminal of the cradle to the holder regardless of whether the holder is at the first position or at the second position, and

the controller detects a user's puff by using the sensor and controls the output units including the LED lamp and the vibration motor based on puff characteristic data corresponding to a result of the detection.

2. The aerosol generating device of claim 1 , wherein

the sensor further comprises a temperature sensor measuring a temperature of the heater, and

the controller detects a user's puff by measuring a variation in the temperature of the heater by using the temperature sensor.

3. The aerosol generating device of claim 1 , wherein

the sensor further comprises a flux sensor, and

the controller detects a user's puff by measuring a variation in flux in the aerosol generating device by using the flux sensor.

4. The aerosol generating device of claim 1 , wherein the puff characteristic data includes at least one of a puff strength, a puff interval, and a number of puffs.

5. The aerosol generating device of claim 1 , wherein the controller predicts a number of available puffs based on power of the battery or an amount of the aerosol generating material, and modifies the predicted number of available puffs based on the puff characteristic data.

6. The aerosol generating device of claim 5 , wherein the controller outputs the modified number of available puffs by using the output units.

7. The aerosol generating device of claim 1 , wherein the controller determines a remaining number of available puffs according to the puff characteristic data and controls an output strength of the vibration motor based on the determined remaining number of available puffs.

8. The aerosol generating device of claim 1 , wherein the controller determines a remaining number of available puffs according to the puff characteristic data and controls an emission intensity or a flickering interval of the LED lamp based on the determined remaining number of available puffs.

9. The aerosol generating device of claim 1 , wherein the controller determines a remaining number of available puffs according to the puff characteristic data and controls a sound output intensity or a type of output sound based on the determined remaining number of available puffs.

10. The aerosol generating 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 the time of a puff.

11. The aerosol generating device of claim 1 , wherein the controller predicts a remaining number of available puffs based on a measured puff strength and an estimated remaining battery power and outputs the predicted remaining number of available puffs.

12. The aerosol generating device of claim 1 , wherein the controller controls the at least one output unit to provide a notification to a user each time a temperature of the heater is raised to a certain temperature or higher.

13. The aerosol generating device of claim 1 , wherein the controller controls the at least one output unit to provide a notification to a user based on a measured puff strength or a measured puff interval.

14. The aerosol generating device of claim 1 , wherein the controller controls the at least one output unit to notify a user, at certain intervals, that puffing is possible.
