AI Technical Summary

Technical Problem

In existing technologies, the air gap between the tubular heating element and the aerosol generating product leads to a reduction in heating speed and efficiency, while the difficulty in inserting the smoke is difficult to balance.

Method used

A heating component was designed, including a base tube and a flared section. The cross-sectional area of ​​the flared section gradually decreases from one end to the other. An isolation layer and a heating structure are provided on the inner and outer sides of the base tube to optimize the insertion and heating efficiency of the aerosol-generated product.

Benefits of technology

By reducing the air gap between the heating element and the aerosol-generated product, heating efficiency is improved, preheating time is shortened, and smooth insertion is ensured.

Abstract

The present application relates to an aerosol generating device and a heating assembly thereof, the heating assembly comprising: a base tube comprising a main body portion and a flared portion provided at one end of the main body portion; and a heating structure provided at an inner side surface and / or an outer side surface of the base tube. The flared portion has a first end away from the main body portion and a second end opposite to the first end, and a cross-sectional area of the flared portion gradually decreases from the first end to the second end. The flared portion provided at one end of the main body portion can ensure smooth insertion of the aerosol generating article, and the inner diameter of the main body portion is relatively small, which can reduce the air gap between the heating assembly and the aerosol generating article, improve the heating efficiency of the heating assembly, and reduce the preheating time.
