Heating device, aerosol generating device, and aerosol generating system

Abstract

A heating device, an aerosol generating device, and an aerosol generating system are provided. The heating device includes a heat preservation assembly and an airflow heating assembly. The heat preservation assembly is internally provided with a receiving cavity. The receiving cavity is configured to accommodate an aerosol generation article. The airflow heating assembly is arranged in the receiving cavity. The airflow heating assembly is configured to heat gas flowing through the airflow heating assembly, so that the heated gas can heat the aerosol generation article placed in the receiving cavity. When the aerosol generation article is placed in the receiving cavity, heat of an inner wall surface of the heat preservation assembly can be transferred to a circumferential outer surface of the aerosol generation article for auxiliary heating.
