AI Technical Summary

Technical Problem

Existing aerosol generating devices experience uneven circumferential heating of the aerosol generation article due to the heating assembly being arranged only at the air inlet end.

Method used

A heating device with a heat preservation assembly and an airflow heating assembly, where the heat preservation assembly includes an inner and outer tube portion with a vacuum or low thermal conductivity medium, and the airflow heating assembly heats gas flowing through it to heat the aerosol generation article placed in the receiving cavity.

Benefits of technology

The solution ensures even heating of the aerosol generation article by transferring heat from the heat preservation assembly to the circumferential outer surface, effectively using the heat and reducing the number of device components.

Abstract

A heating device (100), an aerosol generating device (1000), and an aerosol generating system (10000) are provided. The heating device (100) includes a heat preservation assembly (10) and an airflow heating assembly (20). The heat preservation assembly (10) is internally provided with a receiving cavity (11). The receiving cavity (11) is configured to accommodate an aerosol generation article (2000). The airflow heating assembly (20) is arranged in the receiving cavity (11). The airflow heating assembly (20) is configured to heat gas flowing through the airflow heating assembly (20), so that the heated gas can heat the aerosol generation article (2000) placed in the receiving cavity (11). When the aerosol generation article (2000) is placed in the receiving cavity (11), heat of an inner wall surface of the heat preservation assembly (10) can be transferred to a circumferential outer surface of the aerosol generation article (2000) for auxiliary heating, so that the heat of the heat preservation assembly (10) is effectively used, and parts and components of the heating device (100) are reduced.
