Abstract
An aerosol-generating device comprises an infrared emitter and an electric core for supplying power to the infrared emitter, the infrared emitter comprises at least one first infrared emission region and at least one second infrared emission region arranged in sequence along the circumferential direction of the chamber; the first infrared emission region and the second infrared emission region are independently activatable to independently radiate infrared rays into the chamber to heat different portions of the smokable material. In the above aerosol-generating device, the regions of the smokable material receiving chamber which are different along the circumferential direction correspond to the first infrared emission region and the second infrared emission region, respectively, and can be independently heated by the first infrared emission region and the second infrared emission region, respectively, in use, so that the smokable material can be gradually heated from part to whole in use.
