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 wrapper surrounding the tobacco medium portion and the filter portion, and a cooling portion surrounded by the tobacco medium portion, the filter portion, and the wrapper so as to have a space therein.

1 . An aerosol-generating article comprising:
 a tobacco medium portion;   a filter portion disposed to be spaced apart from the tobacco medium portion;   a wrapper surrounding the tobacco medium portion and the filter portion; and   a cooling portion corresponding to an interior space defined by the tobacco medium portion, the filter portion, and the wrapper.   
     
     
         2 . The aerosol-generating article of  claim 1 , wherein an end of the tobacco medium portion and an end of the filter portion oppose each other with respect to the cooling portion. 
     
     
         3 . The aerosol-generating article of  claim 2 , wherein the space of the cooling portion is formed by the wrapper and the respective ends of the tobacco medium portion and the filter portion. 
     
     
         4 . The aerosol-generating article of  claim 1 , wherein the cooling portion is located between the tobacco medium portion and the filter portion. 
     
     
         5 . The aerosol-generating article of  claim 4 , wherein the wrapper surrounds at least a portion of an outer peripheral surface of each of the tobacco medium portion and the filter portion. 
     
     
         6 . The aerosol-generating article of  claim 5 , wherein the wrapper surrounds the entire outer peripheral surface of each of the tobacco medium portion and the filter portion. 
     
     
         7 . The aerosol-generating article of  claim 5 , wherein the wrapper further extends outwardly beyond the filter portion. 
     
     
         8 . The aerosol-generating article of  claim 1 , wherein the wrapper has a thickness in a range of 100 μm to 350 μm. 
     
     
         9 . The aerosol-generating article of  claim 1 , wherein the wrapper has a basis weight in a range of 80 g/m 2  to 150 g/m 2 . 
     
     
         10 . The aerosol-generating article of  claim 1 , wherein the tobacco medium portion comprises a plurality of segments. 
     
     
         11 . The aerosol-generating article of  claim 10 , wherein at least one of the plurality of segments includes a tobacco medium. 
     
     
         12 . An aerosol-generating device comprising:
 a heater configured to heat at least a portion of the aerosol-generating article of  claim 1 ;   a power supplier configured to supply power to the heater, and   a controller configured to control the power supplied to the power supplier.   
     
     
         13 . The aerosol-generating device of  claim 12 , further comprising an aerosol generator configured to generate an aerosol by heating a liquid composition,
 wherein the aerosol generated by the aerosol generator is introduced into the aerosol-generating article.
