  • Publication number: 20220248758
    Abstract: A cigarette heating assembly, includes a longitudinal heat conductive tube, a substrate layer and a resistance heating trace formed on the substrate layer. The resistance heating trace is located between the substrate layer and the heat conductive tube, and extends along a longitudinal direction of the heat conductive tube. A thermal conductivity of material of the heat conductive tube is larger than a thermal conductivity of material of the substrate layer. On the one hand, properties including electric resistance stability of the resistance heating trace and excellent heat conductivity of the cigarette heating assembly can be maintained. On the other hand, protection on two surfaces of the resistance heating trace is formed so that abrasion of the resistance heating trace caused by physical friction due to use in high temperatures can be avoided.
