Aerosol generating device and method of controlling aerosol generating device

Abstract

An aerosol generating device controls supplying of power to a heater such that a temperature of the heater reaches a temperature lower than a temperature defined in a temperature profile when receiving a user input signal to pause an operation of the aerosol generating device, controls the supplying of power to the heater such that, when the pause is released, the temperature of the heater reaches the temperature defined in the temperature profile, and extends an operation time by a paused time.

What is claimed is: 
     
         1 . An aerosol generating device comprising:
 a heater configured to heat at least part of an aerosol generating article including an aerosol generating material;   a storage storing a temperature profile of the heater and an operation time of the aerosol generating device;   an output unit configured to output a notification corresponding to an operation state of the aerosol generating device; and   a controller configured to control an output of the notification during the operation time and control supplying of power to the heater according to the temperature profile,   wherein, when the controller receives a user input signal to pause an operation of the aerosol generating device, the controller is further configured to control the supplying of power to the heater such that a temperature of the heater reaches a temperature lower than a temperature defined in the temperature profile, and when the pause is released, the controller is further configured to control the supplying of power to the heater such that the temperature of the heater reaches the temperature defined in the temperature profile and to cause the operation time to be extended by a paused time.   
     
     
         2 . The aerosol generating device of  claim 1 , wherein the controller is further configured to cause the output unit to output a reheating completion notification when the temperature of the heater reaches the temperature defined in the temperature profile. 
     
     
         3 . The aerosol generating device of  claim 1 , wherein the controller is further configured to cause the output unit to output a reheating notification when the pause is released and the supplying of power to the heater is controlled such that the temperature of the heater reaches the temperature defined in the temperature profile. 
     
     
         4 . The aerosol generating device of  claim 1 , wherein
 a reheating time for controlling the supplying of power to the heater such that the temperature of the heater reaches the temperature defined in the temperature profile is previously set, and   the controller is further configured to cause the supplying of power to the heater to be maintained until a previously set reheating time when the temperature of the heater reaches the temperature defined in the temperature profile at a time greater than the previously set reheating time, and to cause the output unit to output a reheating completion notification when the previously set reheating time ends.   
     
     
         5 . The aerosol generating device of  claim 4 , wherein the controller is further configured to cause the output unit to output the reheating completion notification even when the temperature of the heater does not reach the temperature defined in the temperature profile within the previously set reheating time. 
     
     
         6 . The aerosol generating device of  claim 4 , wherein the controller is further configured to cause the previously set reheating time to be extended by a preset time when the paused time is greater than a threshold time, and cause the previously set reheating time to be reduced by a preset time when the paused time is less than the threshold time. 
     
     
         7 . The aerosol generating device of  claim 4 , wherein the controller is further configured to cause the output unit to output a notification corresponding to the previously set reheating time. 
     
     
         8 . The aerosol generating device of  claim 1 , wherein the controller is further configured to determine that the pause is released when, after the pause, the user input signal for releasing the pause is received or a previously set pause time elapses. 
     
     
         9 . The aerosol generating device of  claim 1 , wherein the controller is further configured to determine that the pause is released when a movement of the aerosol generating device is detected after the pause. 
     
     
         10 . The aerosol generating device of  claim 1 , wherein the user input signal is a signal corresponding to at least one of a user button input, a user touch, a user puff, and a user gesture. 
     
     
         11 . The aerosol generating device of  claim 1 , wherein the controller is further configured to control the supplying of power to the heater such that the temperature of the heater reaches a temperature higher than the temperature defined in the temperature profile when the pause is released. 
     
     
         12 . The aerosol generating device of  claim 1 , wherein
 the temperature defined in the temperature profile is about 220 degrees to about 300 degrees, and   the temperature lower than the temperature defined in the temperature profile is about 120 degrees to about 180 degrees.   
     
     
         13 . The aerosol generating device of  claim 1 , wherein
 a number of pauses during the operation time of the aerosol generating device is previously set, and   the controller is further configured to cause the output unit to output an unavailability notification when a user input signal to pause a number of times exceeding a previously set number of times is received.   
     
     
         14 . A method of controlling an aerosol generating device, the method comprising:
 receiving a user input signal to pause an operation of the aerosol generating device;   controlling supplying of power to a heater such that a temperature of the heater reaches a temperature lower than a temperature defined in the temperature profile; and   controlling the supplying of power to the heater such that the temperature of the heater reaches the temperature defined in the temperature profile when the pause is released, and extending an operation time of the aerosol generating device by a paused time.   
     
     
         15 . A recording medium having recorded thereon a program for performing, on a computer, the method of controlling the aerosol generating device according to  claim 14 .
