▎ 摘　　要

NOVELTY - The heating rod comprises an insulating column, a graphene heating film coated around the insulating column, and a conductive layer not completely covering the graphene of the heating film. The conductive layers are connected to the power supply through a lead. The heating film graphene is provided with a polymer material film and a graphene layer coated on a surface of the polymer material film. The conductive layer is set on the surface of the graphene layer. The heating film is comprised a shell (200), an inner container set in the shell and a power supply. USE - Heating rod for use in intelligent heating barrel for heating and drying a towel in a toilet. ADVANTAGE - The heating rod can quickly heat the intelligent heating barrel, at the same time, reducing energy consumption, high-efficiency heating. The conductive layer is not completely covered on the graphene of the heating film. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a method for preparing a heating barrel for graphene; and an intelligent heating barrel. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a heating rod for use in intelligent heating barrel. 200Shell
