Aerosol generating device

Abstract

An aerosol generating device includes a cartridge including at least one storage storing an aerosol generating material, a housing including a first accommodation space for accommodating the cartridge and a second accommodation space for accommodating an aerosol generating article, a first heating portion configured to atomize the aerosol generating material, and a second heating portion configured to heat the aerosol generating article, wherein, when the cartridge is accommodated in the first accommodation space, at least a portion of the cartridge is open, and thus, the aerosol generating material is supplied to the first heating portion.

What is claimed is: 
     
         1 . An aerosol generating device comprising:
 a cartridge comprising at least one storage storing an aerosol generating material;   a housing comprising a first accommodation space for accommodating the cartridge and a second accommodation space for accommodating an aerosol generating article;   a first heating portion arranged inside the housing and configured to atomize the aerosol generating material; and   a second heating portion arranged inside the housing and configured to heat the aerosol generating article,   wherein the cartridge is detachably coupled to the first accommodation space,   when the cartridge is accommodated in the first accommodation space, at least a portion of the cartridge is open, and thus, the aerosol generating material is supplied to the first heating portion,   a primary aerosol generated as the aerosol generating material is atomized by the first heating portion enters an end portion of the aerosol generating article accommodated in the second accommodation space, and   the primary aerosol is mixed with a secondary aerosol generated as the aerosol generating article is heated by the second heating portion and is inhaled by a user.   
     
     
         2 . The aerosol generating device of  claim 1 , further comprising a controller electrically connected to the first heating portion and the second heating portion,
 wherein the controller is configured to independently control a temperature of the first heating portion and a temperature of the second heating portion.   
     
     
         3 . The aerosol generating device of  claim 1 , wherein the housing comprises one or more walls surrounding the first accommodation space, and
 the cartridge is inserted into the first accommodation space by moving along the one or more walls in a direction in which the first accommodation space is open.   
     
     
         4 . The aerosol generating device of  claim 1 , wherein the cartridge further comprises a sealing member configured to seal the at least a portion of the cartridge. 
     
     
         5 . The aerosol generating device of  claim 1 , wherein one of the housing and the cartridge further comprises a guide portion configured to guide a supply of the aerosol generating material, and
 the other of the housing and the cartridge further comprises an insertion groove configured to guide insertion of the guide portion, receive the aerosol generating material from the guide portion, and transmit the aerosol generating material to the first heating portion.   
     
     
         6 . The aerosol generating device of  claim 5 , wherein the guide portion is screw-coupled to the insertion groove. 
     
     
         7 . The aerosol generating device of  claim 1 , further comprising a rupture portion configured to rupture the at least a portion of the cartridge when the cartridge is accommodated in the first accommodation space,
 wherein the rupture portion comprises a hollow through which the aerosol generating material moves.   
     
     
         8 . The aerosol generating device of  claim 1 , further comprising a pressing portion configured to open the storage by pressing the at least a portion of the cartridge when the cartridge is accommodated in the first accommodation space. 
     
     
         9 . The aerosol generating device of  claim 8 , wherein the cartridge further comprises a moving member configured to block the at least a portion of the cartridge and moved by the pressing portion. 
     
     
         10 . The aerosol generating device of  claim 9 , wherein the cartridge comprises:
 a support member arranged inside the storage and comprising one or more outlets through which the aerosol generating material passes; and   an elastic member connected to the support member and configured to press the moving member towards an outer side of the storage to block the at least a portion of the cartridge.   
     
     
         11 . The aerosol generating device of  claim 1 , further comprising an adjusting portion arranged between the first accommodation space and the first heating portion and configured to adjust a movement of the aerosol generating material supplied from the storage to the first heating portion. 
     
     
         12 . The aerosol generating device of  claim 11 , wherein the adjusting portion comprises:
 a transmission hole arranged under the adjusting portion and configured to transmit the aerosol generating material existing inside the adjusting portion to the first heating portion; and   an inclined surface that is inclined so that the aerosol generating material moves towards the transmission hole.   
     
     
         13 . The aerosol generating device of  claim 12 , wherein the adjusting portion comprises:
 a blocking member arranged under the transmission hole and configured to block at least a portion of the transmission hole; and   a slot configured to guide a movement of the blocking member.   
     
     
         14 . The aerosol generating device of  claim 11 , wherein the adjusting portion comprises an absorption member configured to contain the aerosol generating material. 
     
     
         15 . The aerosol generating device of  claim 11 , wherein the adjusting portion is arranged in a same number as a number of storages.
