Smoking article and aerosol-generating system

Abstract

A smoking article according to an example embodiment includes a medium receiver filled with a plurality of medium granules, a humectant receiver on one side of the medium receiver and configured to generate an aerosol and a filter on the other side of the medium receiver. The plurality of medium granules have an atypical shape.

1 . A smoking article comprising:
 a plurality of medium granules; and   a medium receiver filled with the plurality of medium granules,   wherein the plurality of medium granules have an atypical shape.   
     
     
         2 . The smoking article of  claim 1 , further comprising:
 a humectant receiver located on one side of the medium receiver and configured to generate an aerosol; and
 a filter located on the other side of the medium receiver. 
   
     
     
         3 . The smoking article of  claim 1 , wherein the medium receiver is configured by folding a flat sheet, to which the plurality of medium granules are applied, a plurality of times. 
     
     
         4 . The smoking article of  claim 3 , wherein a humectant is applied to one surface of the flat sheet. 
     
     
         5 . The smoking article of  claim 1 , wherein the plurality of medium granules have a roundness of 30% or more and 90% or less. 
     
     
         6 . The smoking article of  claim 5 , wherein the roundness is 60% or more and 90% or less. 
     
     
         7 . The smoking article of  claim 1 , wherein the plurality of medium granules are manufactured by a fluidized bed granulation process. 
     
     
         8 . The smoking article of  claim 7 , wherein the fluidized bed granulation process is a process in which a spraying direction of a liquid binder and a flow direction of fluidized air face each other. 
     
     
         9 . The smoking article of  claim 1 , wherein the medium receiver is formed by a method comprising applying a humectant to one surface of a flat sheet, disposing the plurality of medium granules on the one surface of the flat sheet, to which the humectant is applied, folding the one surface of the flat sheet to face each other, additionally folding the flat sheet a plurality of times, and wrapping, with a wrapper, the flat sheet folded a plurality of times. 
     
     
         10 . The smoking article of  claim 9 , wherein the plurality of medium granules not applied to the one surface of the flat sheet are reused in a process of manufacturing the smoking article. 
     
     
         11 . The smoking article of  claim 2 , wherein the filter comprises:
 a first filter having a cavity therein; and   a second filter fully filled with a filtration material.   
     
     
         12 . An aerosol-generating system comprising:
 a smoking article; and   an aerosol-generating device,   wherein the smoking article comprises:
 a medium receiver filled with a plurality of medium granules; 
 a humectant receiver located on one side of the medium receiver and configured to generate an aerosol; and 
 a filter located on the other side of the medium receiver, 
   wherein the aerosol-generating device comprises:
 an elongate cavity configured to accommodate the smoking article; 
 a heater configured to heat at least a portion of the medium receiver and the humectant receiver in the smoking article; and 
 a controller electrically connect to the heater, and 
 wherein the plurality of medium granules have a roundness of 90% or less. 
   
     
     
         13 . The aerosol-generating system of  claim 12 , wherein the plurality of medium granules have a roundness of 60% or more. 
     
     
         14 . The aerosol-generating system of  claim 12 , wherein the plurality of medium granules are manufactured by a process in which a spraying direction of a liquid binder and a flow direction of fluidized air face each other.
