Aerosol generating article and aerosol generating system

Abstract

An aerosol generating article includes an aerosol generating material that is heated by exposure to microwaves and a first capsule that is crushed by exposure to the microwaves, wherein the first capsule includes a first core including a first material and a first microwave-responsive material, and a first shell surrounding the first core.

What is claimed is: 
     
         1 . An aerosol generating article comprising an aerosol generating material that is heated by exposure to microwaves and a first capsule that is crushed by exposure to the microwaves,
 wherein the first capsule comprises:   a first core including a first material and a first microwave-responsive material; and   a first shell surrounding the first core.   
     
     
         2 . The aerosol generating article of  claim 1 , wherein the first material includes at least one selected from the group including a flavoring material, nicotine, caffeine, and cannabinoid. 
     
     
         3 . The aerosol generating article of  claim 1 , wherein each of the microwaves has a frequency of 2.4 GHz to 2.5 GHz. 
     
     
         4 . The aerosol generating article of  claim 1 , wherein the first core includes the first microwave-responsive material with 20 wt % to 40 wt % of a total weight of the first core. 
     
     
         5 . The aerosol generating article of  claim 1 , wherein the first microwave-responsive material includes at least one selected from the group including glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. 
     
     
         6 . The aerosol generating article of  claim 1 , wherein the first shell includes an inner shell including a fat-soluble material and an outer shell surrounding the inner shell and including a water-soluble material. 
     
     
         7 . The aerosol generating article of  claim 6 , wherein the inner shell includes a fat-soluble wax. 
     
     
         8 . The aerosol generating article of  claim 6 , wherein the outer shell includes one or more water-soluble polymers selected from the group consisting of gelatin, agar, carrageenan, gelan gum, pectin, starch, and alginate. 
     
     
         9 . The aerosol generating article of  claim 1 , wherein the first shell has a thickness of 5 μm to 50 μm. 
     
     
         10 . The aerosol generating article of  claim 1 , further comprising:
 an aerosol generating rod including the aerosol generating material and the first capsule, and   a filter rod disposed downstream from the aerosol generating rod.   
     
     
         11 . The aerosol generating article of  claim 1 , further comprising: a second capsule that is crushed by exposure to the microwaves,
 wherein the second capsule includes a second core including a second material and a second microwave-responsive material and a second shell surrounding the second core.   
     
     
         12 . The aerosol generating article of  claim 11 , wherein the first capsule and the second capsule are crushed at different times by exposure to the microwaves. 
     
     
         13 . The aerosol generating article of  claim 11 , wherein the first capsule is disposed upstream from the second capsule and is crushed earlier than the second capsule by exposure to the microwaves. 
     
     
         14 . An aerosol generating system comprising:
 the aerosol generating article according to  claim 1 ; and   an aerosol generating device configured to accommodate the aerosol generating article,   wherein the aerosol generating device includes a heater assembly configured to generate microwaves for heating the aerosol generating article.   
     
     
         15 . The aerosol generating system of  claim 14 , wherein
 the heater assembly includes a resonator configured to generate the microwaves,   the resonator includes a plurality of plates separated from each other in a circumferential direction of the aerosol generating article, and   the microwaves are resonated by the plurality of plates.
