▎ 摘　　要

NOVELTY - The cup has a cup body whose upper end is formed with an opening. A cup cover is connected with the opening of the cup body. An inner surface of the cup body is formed with a gap. An outer circumferential surface of an inner container is covered with a graphene film layer that is arranged with a control circuit through a wire. An outer side of the cup body is provided with a key that is connected with the control circuit. A sounding unit is connected with the control circuit according to a working state of sending different sound to represent the graphene film layer. A temperature sensor is connected with the control circuit. USE - Graphene film heating cup for an automobile. ADVANTAGE - The control circuit controls heating of the graphene film and heating time. The temperature sensor monitors water temperature in real-time and realize water heating and constant temperature controlling in the cup. The cup is convenient to operate, and can increase thickness of the graphene film. The cup body is elongated so as to conveniently allow a user to hold by using hand, and has esthetic appearance, strong practicability, and realizes heating of external power supply voltage in safety range and improves safety and reliability of an automobile. DESCRIPTION OF DRAWING(S) - The drawing shows a side perspective view of a graphene film heating cup.
