Electrically heated smoking article

Abstract

An electrically heated smoking article includes a filter rod, an aerosol medium rod stacked at a lower end of the filter rod and including an aerosol medium that generates an aerosol by heating and a moisture absorbent accommodating or absorbing the aerosol medium, and a wrapping portion surrounding and wrapping the filter rod and the aerosol medium rod to maintain a stack structure. The aerosol medium, including glycerin and a thickener, is maintained in a semi-solid or solid state in a first temperature range including room temperature and is in a liquefied state in a second temperature range higher than the first temperature range. The glycerin vaporizes in a third temperature range higher than the second temperature range to generate an aerosol. The thickener does not vaporize in the third temperature range but remains in the moisture absorbent.

What is claimed is: 
     
         1 . An electrically heated smoking article, comprising:
 a filter rod;   an aerosol medium rod stacked at a lower end of the filter rod and including an aerosol medium that generates an aerosol by heating and a moisture absorbent accommodating or absorbing the aerosol medium; and   a wrapping portion surrounding and wrapping the filter rod and the aerosol medium rod to maintain a stack structure,   wherein the aerosol medium, including glycerin and a thickener, is maintained in a semi-solid or solid state in a first temperature range including room temperature and is in a liquefied state in a second temperature range higher than the first temperature range,   wherein the glycerin vaporizes in a third temperature range higher than the second temperature range to generate an aerosol, and the thickener does not vaporize in the third temperature range but remains in the moisture absorbent.   
     
     
         2 . The electrically heated smoking article of  claim 1 , wherein the thickener includes at least one material selected from the group consisting of monosaccharides, disaccharides, sugar alcohols, and oligosaccharides. 
     
     
         3 . The electrically heated smoking article of  claim 2 , wherein the monosaccharides are plant extracts including at least one substance selected from the group consisting of glucose, fructose, and galactose. 
     
     
         4 . The electrically heated smoking article of  claim 2 , wherein the disaccharides include gradients extracted from sugar. 
     
     
         5 . The electrically heated smoking article of  claim 2 , wherein the sugar alcohols include one or more substances selected from the group consisting of isomalt, maltitol, xylitol, and sorbitol. 
     
     
         6 . The electrically heated smoking article of  claim 2 , wherein the monosaccharides are sugars higher than disaccharides, and include maltodextrin. 
     
     
         7 . The electrically heated smoking article of  claim 1 , wherein the aerosol medium further includes one or more selected from the group consisting of propylene glycol, nicotine, flavoring agents, caffeine, nutritional tonics, water, ethanol, sugar alcohols, and cannabinoids, as an aerosol raw material. 
     
     
         8 . The electrically heated smoking article of  claim 1 , wherein the aerosol medium further includes a flavoring component, and the flavor component includes one or more substances selected from the group consisting of menthol, fruit flavor, herbal flavor, clove or a clove extract. 
     
     
         9 . The electrically heated smoking article of  claim 1 , further comprising a cooling tube rod having a hollow in a vertical direction between the filter rod and the aerosol medium rod. 
     
     
         10 . The electrically heated smoking article of  claim 1 , further comprising a tobacco body rod at the top or bottom of the aerosol medium rod. 
     
     
         11 . The electrically heated smoking article of  claim 1 , further comprising a nicotine rod at the top or bottom of the aerosol medium rod.
