Aerosol Generation Device

Abstract

An aerosol generation system comprises a consumable (100) comprising a vaporizable material, a heating device comprising a heating receptacle (200) for receiving, in use, the consumable and comprising a heating element (204). At least one intermediate element (500) is positioned between the consumable and the heating element for absorbing vaporizable material and for acting as a heatshield between the heating and the consumable.
