▎ 摘　　要

NOVELTY - The boiler has a heating device that is installed inside the cabinet (1). The heating device includes a heating element and a heating element cover. The heating element includes a water tank and a graphene coating plated on the outer wall of the water tank. The supports are installed at the upper and lower ends of the water tank. The heating element cover is connected to the supports at the upper and lower ends. The supports are installed with bumps. The upper support is connected with a tee through the bumps. Two horizontal ports on the left and right of the tee are installed with air discharge pipes and water discharge pipes. The air release pipe is connected with an air release valve. A water pump is installed below the heating device. The upper pipe of the water pump is connected with the lower end support through the convex block. The lower pipe of the water pump is connected with a water inlet (14), and the water discharge pipe is connected with a water outlet (15). USE - Graphene electric wall-hung boiler. ADVANTAGE - The raw graphene materials are saved, the production cost of the graphene electric wall-hung boiler is reduced, the heating area and the heating speed are increased by adopting the three cylindrical water tanks, and the service life of an internal pipeline is prolonged by adopting the corrugated pipe as the water discharge pipe. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural view of a graphene electric wall-hung boiler. Cabinet (1) Cabinet cover (2) Water inlet (14) Water outlet (15) Touch screen (24)
