Title:
HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/143874
Kind Code:
A1
Abstract:
Disclosed is a heating device, which is used for heating an aerosol generating matrix product and volatilizing at least one component therein to form an aerosol. The heating device comprises a heating body (11), wherein the heating body (11) comprises: a substrate (111) provided with a chamber for receiving at least part of the aerosol generating matrix product; an infrared electrothermal coating (112), which is formed on the outer surface of the substrate (111), is used for receiving heat generated through a power supply and transfers the heat to the aerosol generating matrix product received in the chamber at least in an infrared radiation manner, so as to volatilize at least one component in the aerosol generating matrix product to form an aerosol which can be vaped; an electrode coating (113) coating part of the outer surface of the infrared electrothermal coating (112) and used for supplying the electric power of the power supply to the infrared electrothermal coating (112); and an infrared radiation coating (115) at least partially covering the infrared electrothermal coating (112), wherein the infrared radiation coating (115) can radiate infrared rays after a temperature rise. The heating device can improve the power efficiency of the power supply of the infrared electrothermal coating (112).
