AI Technical Summary

Technical Problem

Microwave-heated aerosol generating devices cannot directly detect the temperature inside the heating chamber, resulting in inaccurate adjustment of heating power. Furthermore, the temperature sensor may be damaged by microwaves or the heating efficiency may be reduced.

Method used

Design a heating component comprising a tubular substrate, an antenna, a shield, and a temperature sensor. The sensor probe is located in a second chamber outside the shield. The temperature of the aerosol-generated product is calculated based on the principle of temperature transfer layer by layer, and microwave interference is reduced by the shield.

Benefits of technology

It enables accurate detection of the temperature of aerosol-generated products, avoids sensor damage and reduced heating efficiency, and improves the stability of the heating component and the efficiency of aerosol generation.

Abstract

The application provides a heating assembly and an aerosol generating device. The heating assembly is used for heating an aerosol generating article to generate an aerosol, and comprises a tubular base material, an antenna, a shield and a temperature sensor. The tubular base material defines a first chamber for accommodating the aerosol generating article; the antenna is arranged at least partially on a circumferential side wall of the tubular base material, and is used for emitting radio frequency energy to the first chamber to heat at least part of the aerosol generating article located in the first chamber; the shield is sleeved on the outer periphery of the tubular base material and the antenna, and a second chamber is defined between the shield and the tubular base material; a first opening is arranged on a circumferential side wall of the shield; the temperature sensor comprises a probe and a lead wire, the lead wire is electrically connected to the probe, the lead wire passes through the first opening and is located outside the shield, and the probe is located on one side of the second chamber close to the shield. The application adopts the above technical scheme to obtain the temperature of the aerosol generating article.
