Aerosol generating article and aerosol generating system

Abstract

An aerosol-generating article according to various embodiments may comprise: an atomization segment; and a medium segment which is pH-treated and disposed downstream of the atomization segment, wherein, when the atomization segment is heated, heat of the heated atomization segment is transferred indirectly to the medium segment.

1 . An aerosol generating article comprising:
 an atomization segment; and   a medium segment configured to be pH-treated and disposed downstream of the atomization segment,   wherein, when the atomization segment is heated, heat from the heated atomization segment is transferred indirectly to the medium segment.   
     
     
         2 . The aerosol generating article of  claim 1 , further comprising:
 a filter segment disposed downstream of the medium segment, the filter segment with nicotine adsorbed.   
     
     
         3 . The aerosol generating article of  claim 2 , wherein the nicotine adsorbed into the filter segment is transferred from the medium segment. 
     
     
         4 . The aerosol generating article of  claim 1 , wherein a medium used to fill the medium segment is pH-treated such that the pH thereof is in the range of 7.0 to 9.5. 
     
     
         5 . The aerosol generating article of  claim 1 , further comprising:
 a thermally conductive wrapper configured to wrap the atomization segment.   
     
     
         6 . The aerosol generating article of  claim 5 , wherein the thermally conductive wrapper extends to further wrap the medium segment. 
     
     
         7 . The aerosol generating article of  claim 1 , wherein a medium used to fill the medium segment comprises at least one component of reconstituted tobacco sheets and tobacco granules. 
     
     
         8 . The aerosol generating article of  claim 1 , wherein a moisturizing agent used to fill the atomization segment comprises at least one component of glycerin and propylene glycol. 
     
     
         9 . An aerosol generating system comprising:
 an aerosol generating article comprising an atomization segment, a medium segment disposed downstream of the atomization segment, and a filter segment disposed downstream of the medium segment; and   an aerosol generating device comprising a controller comprising at least one processor; a heater configured to heat the aerosol generating article; and an elongated cavity configured to receive the aerosol generating article,   wherein nicotine is adsorbed into the filter segment.   
     
     
         10 . The aerosol generating system of  claim 9 , wherein a medium used to fill the medium segment is pH-treated, and the nicotine adsorbed into the filter segment is transferred from the medium segment. 
     
     
         11 . The aerosol generating system of  claim 9 , wherein a medium used to fill the medium segment is pH-treated, and when the heater heats the atomization segment, heat from the heated atomization segment is transferred indirectly to the medium segment. 
     
     
         12 . The aerosol generating system of  claim 11 , wherein the aerosol generating article further comprises a thermally conductive wrapper configured to wrap at least one of the atomization segment and the medium segment, the thermally conductive wrapper comprising an aluminum component.
