Aerosol generating article and aerosol generating system

Abstract

An aerosol generating article includes an aerosol generating rod, which includes an aerosol generating material, and a filter rod arranged downstream of the aerosol generating rod and including a capsule. The capsule includes a core region, a first shell, and a second shell, and the core region includes a phenol reduction material.

What is claimed is: 
     
         1 . An aerosol generating article comprising:
 an aerosol generating rod comprising an aerosol generating material; and   a filter rod arranged downstream of the aerosol generating rod and comprising a capsule, wherein   the capsule comprises a core region, a first shell, and a second shell, and   the core region comprises a phenol reduction material.   
     
     
         2 . The aerosol generating article of  claim 1 , wherein the phenol reduction material comprises polyethylene glycol that is a water-soluble material. 
     
     
         3 . The aerosol generating article of  claim 2 , wherein the polyethylene glycol is in a liquid state, and a molecular weight of the polyethylene glycol is in a range from about 200 to about 600. 
     
     
         4 . The aerosol generating article of  claim 1 , wherein the core region further comprises a water-soluble flavoring material. 
     
     
         5 . The aerosol generating article of  claim 1 , wherein the first shell comprises an oil-soluble material, and the second shell surrounds the first shell and comprises a water-soluble material. 
     
     
         6 . The aerosol generating article of  claim 5 , wherein the first shell comprises one or more of carnauba wax, candelilla wax, castor wax, ouricury wax, cocoa butter, and shea butter. 
     
     
         7 . The aerosol generating article of  claim 5 , wherein
 the second shell comprises one or more water-soluble polymers selected from a group consisting of gelatin, agar, carrageenan, gellan gum, pectin, starch, and alginate.   
     
     
         8 . The aerosol generating article of  claim 1 , wherein a diameter of the capsule is about 2.6 mm to about 8.5 mm, and a crushing strength of the capsule is about 0.5 kgf to about 3.0 kgf. 
     
     
         9 . The aerosol generating article of  claim 1 , wherein the filter rod comprises a lyocell tow comprising a plurality of lyocell fibers. 
     
     
         10 . The aerosol generating article of  claim 9 , wherein each of the plurality of lyocell fibers has a non-circular cross-section. 
     
     
         11 . The aerosol generating article of  claim 9 , wherein the phenol reduction material does not comprise a material for combination among the plurality of lyocell fibers. 
     
     
         12 . The aerosol generating article of  claim 1 , wherein the aerosol generating article comprises a wrapper covering the aerosol generating rod and the filter rod. 
     
     
         13 . An aerosol generating system comprising:
 an aerosol generating article comprising an aerosol generating rod and a filter rod, wherein the aerosol generating rod comprises an aerosol generating material and the filter rod is arranged adjacent to the aerosol generating rod and comprises a capsule; and   an aerosol generating device comprising an insertion space and a heater, wherein the insertion space is used for accommodating the aerosol generating article and the heater is arranged to correspond to the aerosol generating rod around the insertion space, wherein   the capsule comprises a core region, a first shell, and a second shell, and the core region comprises a phenol reduction material.   
     
     
         14 . The aerosol generating system of  claim 13 , wherein the phenol reduction material comprises polyethylene glycol that is a water-soluble material. 
     
     
         15 . The aerosol generating system of  claim 14 , wherein the polyethylene glycol is in a liquid state, and a molecular weight of the polyethylene glycol is in a range from about 200 to about 600.
