Abstract

The invention provides a heater and an aerosol generating device. The heater comprises a substrate; an infrared electro-thermal film, which is formed on the surface of the substrate, and contains doped tin oxide, wherein doping elements of the doped tin oxide comprise non-metallic elements, and the infrared electro-thermal film is used for generating infrared rays and heating the aerosol forming substrate at least in a radiation mode; and a conductive part, which comprises a first electrode and a second electrode which are arranged on the substrate, wherein the first electrode and the second electrode are electrically connected with the infrared electro-thermal film so as to feed the electric power of a power supply to the infrared electro-thermal film. The infrared electro-thermal film is formed on the substrate and contains the doped tin oxide, and the doping elements of the tin oxide is beneficial to improving the conductivity and the infrared radiation efficiency of the infrared electro-thermal film; and when the aerosol forming substrate is heated through infrared radiation of the infrared electro-thermal film, the center temperature of the aerosol forming substrate is high, heating is uniform, and the preheating time is short.

Description

technical field [0001] The present application relates to the technical field of smoking appliances, in particular to a heater and an aerosol generating device. Background technique [0002] Smoking articles such as cigarettes and cigars burn tobacco to produce smoke during use. Attempts have been made to provide alternatives to these tobacco burning articles by creating products that release compounds without burning them. Examples of such products are so-called heat-not-burn products, which release compounds by heating tobacco rather than burning it. [0003] An existing heat-not-burn smoking appliance mainly generates heat through a heating element, and conducts the heat to the aerosol-generating matrix in the chamber, so that at least one component in it volatilizes to form an aerosol for the user to smoke. This heating method The temperature rises quickly, but there are problems of low heat conduction efficiency, slow warm-up of the aerosol-generating matrix, and diff...
