Aerosol Generation Article

Abstract

An aerosol generation article includes a housing, a substrate arranged within the housing, the substrate configured to generate an aerosol when heated; at least one heating element arranged within the housing and adjacent the substrate; wherein each heating element includes: a susceptor; and an insulator; wherein the susceptor and the insulator, with the insulator at least partially surrounding the susceptor, are configured such that, in use, when an electromagnetic field is applied by an aerosol generation device, the heating element heats the adjacent substrate without damaging the housing of the article.

1 . An aerosol generation article comprising:
 a housing,   a substrate arranged within the housing, the substrate configured to generate an aerosol when heated;   at least one heating element arranged within the housing and adjacent the substrate;   wherein each heating element comprises:
 a susceptor; and 
 an insulator, wherein the insulator comprises a solid insulator material; 
 wherein the susceptor and the insulator, with the insulator at least partially surrounding the susceptor and contacting the susceptor, are configured such that, in use, when an electromagnetic field is applied by an aerosol generation device, the heating element heats the adjacent substrate without damaging the housing of the article. 
   
     
     
         2 . The article of  claim 1 , wherein the article is an elongate shape such that an article axis is defined between two longitudinally opposing ends of the article. 
     
     
         3 . The article of  claim 2 , wherein the susceptor comprises a first end and a second end, and the heating element is arranged within the housing such that the first end and the second end are axially aligned along the article axis. 
     
     
         4 . The article of  claim 3 , wherein the insulator surrounds the susceptor such that the first end and the second end of the susceptor are exposed by the insulator. 
     
     
         5 . The article of  claim 1 , wherein the insulator fully encapsulates the susceptor. 
     
     
         6 . The article of  claim 1 , wherein the susceptor is a cylindrical tube shape. 
     
     
         7 . The article of  claim 6 , wherein a thickness of the tube walls is between 50 μm and 150 μm. 
     
     
         8 . The article of  claim 1 , wherein the insulator is substantially the same shape as the susceptor. 
     
     
         9 . The article of  claim 1 , wherein the insulator comprises a plurality of projections of insulator material extending from the heating element. 
     
     
         10 . The article of  claim 9 , wherein the plurality of projections extend from the heating element perpendicularly to a longitudinal axis of the article. 
     
     
         11 . The article of  claim 1 , wherein an outer diameter of the heating element is between 5 mm and 8 mm. 
     
     
         12 . The article of  claim 1 , wherein a length of the heating element is greater than or equal to 6 mm. 
     
     
         13 . The article of  claim 1 , wherein the at least one heating element comprises a plurality of heating elements. 
     
     
         14 . The article of  claim 13 , wherein the plurality of heating elements are axially aligned with a longitudinal axis of the article and sequentially arranged along a length of the article, and wherein the substrate is arranged between adjacent heating elements. 
     
     
         15 . An aerosol generation system comprising:
 the aerosol generation article of  claim 1 ; and   an aerosol generation device comprising a heating chamber and at least one induction coil;   wherein, in use, the device is configured to receive the article in the heating chamber such that the induction coil is aligned with the susceptor.
