Aerosol-generating article and aerosol-generating device

Abstract

An aerosol-generating article includes a first filter segment disposed at the upstream end of the aerosol-generating article, a second filter segment disposed downstream of the first filter segment, and a cavity segment disposed between the first filter segment and the second filter segment, and the cavity segment is filled with medium pulp and flavoring agent pulp.

What is claimed is: 
     
         1 . An aerosol-generating article, the article comprising:
 a first filter segment disposed at an upstream end of the aerosol-generating article;   a second filter segment disposed downstream of the first filter segment; and   a cavity segment disposed between the first filter segment and the second filter segment,   wherein the cavity segment is filled with medium pulp and flavoring agent pulp.   
     
     
         2 . The article of  claim 1 , wherein a proportion of the medium pulp is 50% or more of a total amount of pulp included in the cavity segment. 
     
     
         3 . The article of  claim 1 , wherein the medium pulp and the flavoring agent pulp have a same density or a same particle size. 
     
     
         4 . The article of  claim 1 , wherein the aerosol-generating article further comprises a filter rod disposed downstream of the second filter segment,
 wherein the filter rod comprises a cooling segment and a mouthpiece segment.   
     
     
         5 . The article of  claim 4 , wherein the mouthpiece segment comprises a flavoring agent material. 
     
     
         6 . The article of  claim 5 , wherein the mouthpiece segment comprises a transfer jet nozzle system (TJNS) filter,
 wherein the TJNS filter is flavored with the flavoring agent material.   
     
     
         7 . The article of  claim 1 , wherein the medium pulp comprises a pH adjuster which is alkaline. 
     
     
         8 . The article of  claim 1 , wherein the flavoring agent pulp is manufactured by a fluidized bed granulation process. 
     
     
         9 . An aerosol-generating device, the device comprising:
 a receiver for receiving an aerosol-generating article according to  claim 1 ;   an atomizer that generates aerosol; and   a power supply for transmitting power to the atomizer,   wherein the aerosol generated by heating of the atomizer passes through the aerosol-generating article such that the medium pulp and the flavoring agent pulp are vaporized and transferred by the aerosol.   
     
     
         10 . The device of  claim 9 , wherein the atomizer comprises:
 a liquid storage tank for storing a liquid composition material configured to generate the aerosol when heated;   a heater for heating the liquid composition material; and   a liquid transfer means configured to transfer of the liquid composition material from the liquid storage tank to the heater.   
     
     
         11 . The device of  claim 10 , wherein the liquid composition material further comprises a flavoring agent. 
     
     
         12 . The device of  claim 10 , wherein a heating temperature of the heater is 300° C. or less.
