Reinforced heat source

Abstract

A reinforced heat source ( 4 ) for an aerosol-generating article ( 2 ), the reinforced heat source comprising: a blind combustible heat source ( 38 ) having a length L; and a non-combustible support ( 40 ) embedded in the combustible heat source, wherein the non-combustible support does not protrude outwardly from the combustible heat source.

1 . A reinforced heat source for an aerosol-generating article, the reinforced heat source comprising:
 a blind combustible heat source having a length L; and   a non-combustible support embedded in the combustible heat source, wherein the non-combustible support does not protrude outwardly from the combustible heat source.   
     
     
         2 . A reinforced heat source according to  claim 1  wherein the combustible heat source completely surrounds the non-combustible support. 
     
     
         3 . A reinforced heat source according to  claim 1  wherein the non-combustible support extends a distance of between about 0.4 L and about 0.9 L within the combustible heat source. 
     
     
         4 . A reinforced heat source according to  claim 1  wherein the non-combustible support is formed from one or more materials having a melting point of greater than or equal to about 1300° C. 
     
     
         5 . A reinforced heat source according to  claim 1  wherein the non-combustible support is formed from one or materials selected from the group consisting of chromium, iron, nickel and steel. 
     
     
         6 . A reinforced heat source according to  claim 1  wherein the non-combustible support comprises one or more non-combustible support elements. 
     
     
         7 . A reinforced heat source according to  claim 6  wherein the one or more non-combustible support elements have a length of between about 0.4 L and about 0.9 L. 
     
     
         8 . A reinforced heat source according to  claim 6  wherein the combustible heat source has a volume V and the total volume of the one or more non-combustible support elements is between about 0.00005V and about 0.05V. 
     
     
         9 . A reinforced heat source according to  claim 1  wherein the non-combustible support comprises one or more elongate rods. 
     
     
         10 . A reinforced heat source according to  claim 9  wherein the combustible heat source has a diameter D and the one or more elongate rods have a diameter of between about 0.01 D and about 0.3 D. 
     
     
         11 . A reinforced heat source according to  claim 1  wherein the non-combustible support is formed from a mesh. 
     
     
         12 . A reinforced heat source according to  claim 1  wherein the combustible heat source comprises an oxidizing agent. 
     
     
         13 . A reinforced heat source according to  claim 12  wherein the oxidizing agent is an alkaline earth metal peroxide. 
     
     
         14 . A reinforced heat source according to  claim 12  wherein the oxidizing agent is calcium peroxide. 
     
     
         15 . An aerosol-generating article comprising:
 a reinforced heat source according to  claim 1 ; and   an aerosol-generating substrate.
