Abstract

The present application belongs to the technical field of electronic cigarettes. The present application provides an atomizing core, including a substrate, where a tantalum thin-film is provided on the surface of the heating film away from the substrate; where the heating film is made of elemental metal or an alloy material having a melting point of 1400 °C or more, and a resistivity of less than 5 × 10<-7> Ωm, and the resistance of the tantalum thin-film is at least five times the resistance of the heating film. According to atomizing core of the present application, it is ensured that current mainly passes through a layer of the heating film having a low resistance. The amount of heat generated by the tantalum thin-film is not high, and the heat is mainly concentrated at the end of the heating film. This can effectively improve the high-temperature oxidation resistance of the heating film and the tantalum thin-film, enabling the entire atomizing core to have a strong resistance to dry-heating. In addition, the tantalum thin-film can significantly prevent the high-temperature electrochemical corrosion of a heating thin-film by an atomizing substrate, which improves the high-temperature wet-heating resistance and prolongs the service life. Therefore, the atomizing core of the present application has strong resistance to both dry-heating and wet-heating, and is a long-life atomizing core.
