Aerosol-generating article

Abstract

An aerosol-generating article according to one aspect of the present disclosure may include a tobacco medium portion, a filter portion disposed to be spaced apart from the tobacco medium portion, a cooling portion disposed between the tobacco medium portion and the filter portion, and a heat transfer portion surrounding at least a portion of the cooling portion.

1 . An aerosol-generating article comprising:
 a tobacco medium portion;   a filter portion;   a cooling portion disposed between the tobacco medium portion and the filter portion; and   a heat transfer portion surrounding at least a portion of the cooling portion.   
     
     
         2 . The aerosol-generating article of  claim 1 , wherein an edge of the heat transfer portion is positioned to surround a portion of the aerosol-generating article corresponding to an inlet of the cooling portion in contact with the tobacco medium portion. 
     
     
         3 . The aerosol-generating article of  claim 2 , wherein the cooling portion comprises:
 a first cooling segment in contact with the tobacco medium portion; and   a second cooling segment disposed between the first cooling segment and the filter portion.   
     
     
         4 . The aerosol-generating article of  claim 3 , wherein the heat transfer portion surrounds at least a portion of the first cooling segment. 
     
     
         5 . The aerosol-generating article of  claim 4 , wherein the heat transfer portion surrounds at least a portion of the second cooling segment. 
     
     
         6 . The aerosol-generating article of  claim 3 , wherein the first cooling segment includes a cellulose acetate tow, and the second cooling segment includes a paper material. 
     
     
         7 . The aerosol-generating article of  claim 1 , wherein the cooling portion has a tubular shape. 
     
     
         8 . The aerosol-generating article of  claim 1 , wherein the tobacco medium portion comprises a plurality of segments. 
     
     
         9 . The aerosol-generating article of  claim 8 , wherein at least one of the plurality of segments includes a tobacco medium. 
     
     
         10 . The aerosol-generating article of  claim 1 , wherein the heat transfer portion is in the form of a metal foil. 
     
     
         11 . The aerosol-generating article of  claim 10 , wherein the heat transfer portion includes at least one of aluminum, copper, ferrite, or martensite. 
     
     
         12 . The aerosol-generating article of  claim 10 , wherein the heat transfer portion comprises a plurality of metal strips. 
     
     
         13 . The aerosol-generating article of  claim 12 , wherein the plurality of metal strips are spaced apart from each other. 
     
     
         14 . The aerosol-generating article of  claim 13 , wherein the plurality of metal strips are arranged to be parallel to a lengthwise direction of the cooling portion. 
     
     
         15 . The aerosol-generating article of  claim 13 , wherein the plurality of metal strips are arranged obliquely with respect to a lengthwise direction of the cooling portion.
