Heating plate: Through material innovation and structural optimization, the heating plates in atomizer cores have formed core competitiveness in terms of thermal conductivity efficiency, atomization fineness, flavor reproduction, and durability. Technological iterations (such as the evolution from traditional metal wires to MESH mesh sheets and nano-coatings) continue to drive e-cigarettes toward higher efficiency and better taste. When selecting heating plates, it is essential to consider the type of e-liquid, device power, and user preferences to match the optimal heating plate solution. The utility model discloses a planar metal low-temperature heating device, which relates to the technical field of low-temperature heating cigarettes. It includes an external protective glaze layer, a metal support sheet layer, an insulating medium layer, a support layer, and a metal heating trace layer. The insulating medium layer is coated on the outer surface of the metal support sheet layer. The metal heating trace layer is embedded in the support layer, and the metal heating trace layer and the support layer form a filling layer, which is attached to the upper surface of the insulating medium layer. The external protective glaze layer wraps the filling layer and the insulating medium layer. Both ends of the metal heating trace layer extend from the external protective glaze layer and are respectively connected to the positive and negative poles of the power supply. The beneficial effects of the utility model are as follows: Using metal materials as the support body features good toughness, eliminating the problem of circuit open circuit caused by slight bending. 1.Rapid Response, Enhanced Vaporization 2.Precise Temp Control, Consistent Taste 3.Universal Temperature Compatibility 4.Leak-Proof & Corrosion Resistance 5.Lightweight & Scalable Production
