AI Technical Summary

Technical Problem

Existing heat-not-burning aerosol generating devices require separate temperature measurement sensors, which occupy space and complicate installation.

Method used

Incorporating a heating element with a temperature coefficient of resistance (TCR) characteristic into the heating assembly, which functions as a temperature sensor, eliminating the need for separate sensors and allowing for direct deposition on the surface, thus reducing space and simplifying installation.

Benefits of technology

The heating element provides accurate temperature measurement over a wide range, optimizing heating uniformity and smoking sensation without the need for additional mounting components, enhancing the efficiency and convenience of the heating assembly.

Abstract

A heating assembly and an aerosol generating device are provided. The heating assembly (10) includes a body (11) for accommodating an aerosol-generating substrate, an infrared layer (12) provided on the surface of the body (11) and / or the infrared layer (12) for heating and atomizing the aerosol-generating substrate by emitting infrared rays when heated, and a heating element (13) provided on the body (11) for heating the infrared layer (12) when energized, the heating element (13) having a resistance temperature coefficient characteristic and therefore capable of functioning as a temperature sensor. The heating assembly (10) is easy to arrange and occupies a small space.
