Aerosol Generating System

Abstract

An aerosol generating system comprises a conically shaped heating element (101) configured to generate an aerosol by evaporating a vaporizable material on a slanted surface (104), and a vaporizable material capsule (102) configured to contain a vaporizable material (103), whereby the vaporizable material capsule comprises a conically shaped contacting element having a slanted surface (105) configured to mate with the conically shaped heating element in use. An interfacing layer (106) is arranged in said gap contacting the slanted surfaces of both the heating element and contacting element, the interfacing layer comprising a porous material configured to wick vaporizable material from the slanted surface of the contacting element to the slanted surface of the heating element, and an airflow management system is arranged in the vicinity of the interfacing layer, including fresh air grooves (200) and airflow channel grooves (201) in the walls of the conically shaped contacting element and/or in the slanted surface of the conically shaped heating element, and configured respectively to conduct fresh air or the aerosol.
