Aerosol generator and aerosol generating device including the same

Abstract

An aerosol generating device includes an aerosol generator, which includes a storage configured to store an aerosol generating material, a transfer portion configured to perform at least one of a function of receiving the aerosol generating material from the storage and filtering out foreign substances from the aerosol generating material, and a function of adding, to the aerosol generating material, an additive material that changes properties of the aerosol generating material, and a generation portion configured to receive the aerosol generating material from the transfer portion and generate an aerosol, and a coupling portion coupled to the aerosol generator.

1 . An aerosol generator comprising:
 a storage configured to store an aerosol generating material;   a transfer portion configured to perform at least one of a function of receiving the aerosol generating material from the storage and filtering out foreign substances from the aerosol generating material, and a function of adding, to the aerosol generating material, an additive material that changes properties of the aerosol generating material; and   a generation portion configured to receive the aerosol generating material from the transfer portion and generate an aerosol.   
     
     
         2 . The aerosol generator of  claim 1 , wherein the transfer portion is detachably coupled to at least one of the storage and the generation portion. 
     
     
         3 . The aerosol generator of  claim 1 , wherein the transfer portion includes a carbon structure including activated carbon and configured to prevent the foreign substances included in the aerosol generating material from being transferred to the generation portion, by filtering out the foreign substances of a certain size or larger from the aerosol generating material. 
     
     
         4 . The aerosol generator of  claim 1 , wherein the transfer portion includes granular activated carbon including a plurality of granules. 
     
     
         5 . The aerosol generator of  claim 1 , wherein the transfer portion includes a carbon block made of a solid material including carbon. 
     
     
         6 . The aerosol generator of  claim 1 , wherein the transfer portion includes a mesh structure configured to filter out a material of a certain size or larger from the aerosol generating material to prevent the material from being transferred to the generation portion. 
     
     
         7 . The aerosol generator of  claim 1 , wherein the transfer portion includes a fiber structure configured to filter out a material of a certain size or larger from the aerosol generating material to prevent the material from being transferred to the generation portion. 
     
     
         8 . The aerosol generator of  claim 1 , wherein the transfer portion includes a ceramic structure of a ceramic material configured to filter out a material of a certain size or larger from the aerosol generating material to prevent the material from being transferred to the generation portion. 
     
     
         9 . The aerosol generator of  claim 1 , wherein the transfer portion includes a flavoring material configured to provide flavor to the aerosol generating material. 
     
     
         10 . The aerosol generator of  claim 1 , wherein the transfer portion includes a viscous material configured to control viscosity of the aerosol generating material. 
     
     
         11 . An aerosol generating device comprising:
 the aerosol generator of any one of claims  1  to  10 ; and   a coupling portion coupled to the aerosol generator.   
     
     
         12 . The aerosol generating device of  claim 11 , wherein the aerosol generator is detachably coupled to the coupling portion. 
     
     
         13 . The aerosol generating device of  claim 11 , wherein
 the transfer portion is detachably coupled to at least one of the storage and the generation portion, and   the aerosol generating device further comprises an output unit configured to output information on replacement of the transfer portion when a replacement cycle of the transfer portion expires.   
     
     
         14 . The aerosol generating device of  claim 11 , further comprising an opening configured to receive a medium such that an aerosol generated by the aerosol generator is discharged to outside through the medium.
