Aerosol generating device and method of controlling aerosol generating device

Abstract

An aerosol generating device includes a heater heating at least part of an aerosol generating article including an aerosol generating material, a storage storing a temperature profile of the heater and operation time of the aerosol generating device, an output unit outputting a notification corresponding to an operation state of the aerosol generating device, a puff sensor detecting a user's puff during the operation time, and a controller controlling an output of the notification based on at least one of the operation time and a previously determined puff number, and supplying of power of the heater to correspond to the temperature profile, wherein the controller determines an additional puff number provided additionally to the previously determined puff number based on time taken to reach a preset puff number within the previously determined puff number and controls the output unit to output a notification corresponding to the determined additional puff number.

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;   a puff sensor configured to detect a user's puff during the operation time; and   a controller configured to control an output of the notification based on at least one of the operation time and a previously determined puff number, and control supplying of power of the heater to correspond to the temperature profile,   wherein the controller is further configured to determine an additional puff number provided in addition to the previously determined puff number based on a time taken to reach a preset puff number within the previously determined puff number, and control the output unit to output a notification corresponding to the determined additional puff number.   
     
     
         2 . The aerosol generating device of  claim 1 , wherein the controller is further configured to determine the additional puff number when the time taken to reach the preset puff number is less than a first threshold time within the previously determined puff number. 
     
     
         3 . The aerosol generating device of  claim 2 , wherein the controller is further configured to calculate an average puff time based on the time taken to reach the preset puff number, and determine the additional puff number based on a remaining operation time obtained by subtracting the time taken to reach the preset puff number from the operation time, the previously determined puff number, and the average puff time. 
     
     
         4 . The aerosol generating device of  claim 3 , wherein the average puff time is a cumulative average value of time including an inhalation time of the user and an interval between inhalations. 
     
     
         5 . The aerosol generating device of  claim 3 , wherein
 the storage stores the average puff time previously calculated according to an accumulated use of the aerosol generating device, and   the controller is further configured to determine the additional puff number based on the average puff time stored in the storage.   
     
     
         6 . The aerosol generating device of  claim 1 , wherein
 the temperature profile includes a plurality of temperature profiles, and   the controller is further configured to determine the additional puff number differently according to the plurality of temperature profiles.   
     
     
         7 . The aerosol generating device of  claim 6 , wherein
 the plurality of temperature profiles include: a first mode for controlling the supplying of power of the heater according to a first temperature profile having a first average temperature; and a second mode for controlling the supplying of power of the heater according to a second temperature profile having a second average temperature higher than the first average temperature, and   the controller is further configured to assign a weight to the first mode rather than to the second mode when determining the additional puff number.   
     
     
         8 . The aerosol generating device of  claim 1 , wherein the controller is further configured to cause the output unit to output a remaining puff number according to the previously determined puff number. 
     
     
         9 . The aerosol generating device of  claim 8 , wherein the controller is further configured to cause the output unit to output the determined additional puff number, when the additional puff number is determined. 
     
     
         10 . The aerosol generating device of  claim 9 , wherein the controller is further configured to cause the output unit to output a final remaining puff number obtained by adding the determined additional puff number to the remaining puff number. 
     
     
         11 . The aerosol generating device of  claim 1 , wherein the controller is further configured to determine the additional puff number based on a minimum transfer amount of the aerosol generating material according to the user's puff during the operation time. 
     
     
         12 . The aerosol generating device of  claim 1 , wherein the controller is further configured to determine the additional puff number based on intensity of the user's puff during the operation time. 
     
     
         13 . The aerosol generating device of  claim 1 , wherein the controller is further configured to determine the additional puff number as a minimum number when the time taken to reach the preset puff number within the previously determined puff number is less than a first threshold time. 
     
     
         14 . A method of controlling an aerosol generating device, the method comprising:
 determining a time taken to reach a preset puff number within a previously determined puff number;   determining an additional puff number provided additionally to the previously determined puff number based on the time taken to reach the preset puff number; and   outputting a notification corresponding to the determined additional puff number.   
     
     
         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 .
