AI Technical Summary

Technical Problem

The heating element of the existing aerosol generating device has the problems of low carbonization rate of the cigarette core, large volume, slow heating rate, complex production process, and is not suitable for short and thick aerosol generating products.

Method used

Design a heating element assembly that contains two or more heating units arranged side by side to form a hollow columnar structure. The heating units are fixed with insulating glue or fixings to achieve circumferential heating, and each heating unit is controlled independently or programmatically. The startup is suitable for short and thick aerosol-generating products.

Benefits of technology

It achieves uniform release of aerosol-generated products, simplifies the production process, shortens the length of the heating element, makes it easier for customers to carry, and improves the circumferential segmented heating effect.

Abstract

This utility model belongs to the field of heating devices, specifically relating to a heating element assembly and an aerosol generating device. The heating element assembly includes: two or more heating units arranged side-by-side; a cavity for receiving the aerosol-generated product at the center of the heating element assembly; and two or more heating units arranged around the cavity for receiving the aerosol-generated product, with the heating units insulated from each other. By controlling the start and stop times of each heating unit, the circumferential heating element assembly of this utility model can achieve the effect of circumferential segmented heating of the aerosol-generated product, ensuring that the aerosol is released more evenly throughout the entire inhalation cycle. This solves the problem of insufficient smoke volume in the later stages of conventional aerosol-generated products.
