Abstract

An aerosol generating device and a method of operating the same are provided. The aerosol generating device includes: a cartridge having a chamber in which an aerosol generating substance is stored; a body to which the cartridge is coupled; a liquid delivery portion connected to the chamber; a heater to heat the liquid delivery portion; and at least one processor to control supply of power to the heater, wherein the at least one processor is configured to, based on coupling of the cartridge to the body or removal of the cartridge from the body, control the supply of power to the heater, so as to cause a temperature of the heater to increase above a vaporization temperature of an aerosol generating substance in the liquid delivery portion.

1 . An aerosol generating device comprising:
 a cartridge having a chamber in which an aerosol generating substance is stored;   a body to which the cartridge is configured to be coupled;   a liquid delivery portion connected to the chamber;   a heater configured to heat the liquid delivery portion; and   at least one processor configured to control supply of power to the heater,   wherein the at least one processor is further configured to, based on coupling of the cartridge to the body or removal of the cartridge from the body, control the supply of power to the heater, so as to cause a temperature of the heater to increase above a vaporization temperature of an aerosol generating substance in the liquid delivery portion.   
     
     
         2 . The aerosol generating device of  claim 1 , wherein the at least one processor is further configured to, based on the coupling of the cartridge to the body or the removal of the cartridge from the body, control the supply of power to the heater for a predetermined of time, so as to cause the temperature of the heater to increase above the vaporization temperature of the aerosol generating substance in the liquid delivery portion. 
     
     
         3 . The aerosol generating device of  claim 1 , wherein the at least one processor is further configured to:
 monitor the temperature of the heater; and   based on the temperature of the heater being greater than or equal to a reference temperature, cut off the supply of power to the heater.   
     
     
         4 . The aerosol generating device of  claim 3 , wherein the heater has a resistance that changes according to the temperature of the heater, and
 wherein the at least one processor is further configured to determine the temperature of the heater based on a temperature coefficient of the resistance of the heater.   
     
     
         5 . The aerosol generating device of  claim 1 , further comprising a cartridge detection sensor configured to detect the coupling of the cartridge to the body and the removal of the cartridge from the body,
 wherein the at least one processor is further configured to, based on a signal received from the cartridge detection sensor, detect the coupling of the cartridge to the body or the removal of the cartridge from the body.   
     
     
         6 . The aerosol generating device of  claim 5 , further comprising a memory configured to store information regarding types of cartridges being coupled to the body,
 wherein the cartridge detection sensor is further configured to, based on the coupling of the cartridge to the body, receive information about the cartridge, and   wherein the at least one processor is further configured to:   based on the information received by the cartridge detection sensor, determine a type of the cartridge; and   control the supply of power to the heater based on whether the determined type of the cartridge corresponds to a type of a cartridge most recently coupled to the body and used.   
     
     
         7 . The aerosol generating device of  claim 6 , wherein the at least one processor is further configured to, based on the determined type of the cartridge not corresponding to the type of the cartridge most recently coupled to the body and used, control the supply of power to the heater, so as to cause the temperature of the heater to increase above the vaporization temperature of the aerosol generating substance in the liquid delivery portion. 
     
     
         8 . The aerosol generating device of  claim 6 , wherein the type of the cartridge is determined based on a type of the aerosol generating substance stored in the chamber or a type of a flavoring or a flavoring agent included in the aerosol generating substance stored in the chamber. 
     
     
         9 . The aerosol generating device of  claim 1 , further comprising an input device configured to receive a user input,
 wherein the cartridge has a plurality of chambers, the plurality of chambers respectively storing therein different aerosol generating substances, and   wherein the at least one processor is further configured to:   based on the user input received by the input device, identify a chamber selected by a user from among the plurality of chambers; and   based on the selected chamber being changed according to the user input, control the supply of power to the heater, so as to cause the temperature of the heater to increase above the vaporization temperature of the aerosol generating substance in the liquid delivery portion.   
     
     
         10 . A method of operating an aerosol generating device comprising a heater, a cartridge having a chamber, a liquid delivery portion connected to the chamber, and a body to which the cartridge is configured to be coupled, the method comprising:
 detecting coupling of the cartridge to the body or removal of the cartridge from the body; and   based on the coupling of the cartridge to the body or the removal of the cartridge from the body being detected, control a supply of power to the heater, so as to cause a temperature of the heater to increase above a vaporization temperature of an aerosol generating substance in the liquid delivery portion.
