Aerosol generating device

Abstract

An aerosol generating device for generating an aerosol from aerosol-generating material. The device has a receptacle defining a heating zone configured to receive at least a portion of an article including aerosol-generating material. A first heating element protrudes in the heating zone and heats the heating zone. A second heating element protrudes in the heating zone and heats the heating zone. The first heating element protrudes from a different side of the heating zone than the second heating element.
