Abstract

This application provides a preform for a heating module, a heating module, and an electronic cigarette device, relating to the technical field of electronic cigarette devices. The preform for the heating module is used to roll and form the heating module, including a heat insulation film and a graphene heating element, wherein the heat insulation film is insulated; the graphene heating element is disposed on the heat insulation film. By incorporating the graphene heating element, this application achieves an electrothermal conversion rate of over 80%, which is significantly higher than the 30%–40% electrothermal conversion rate of traditional metal circuit heating wires. Furthermore, the graphene heating element can eliminate the need for gaps or reduce the gaps, thereby improving the uniformity of the heating element. In addition, the graphene heating element can maintain a relatively stable heating effect over a long period, without localized overheating or excessive temperature fluctuations, thus eliminating the need for existing heat-conducting components.
