▎ 摘　　要

NOVELTY - The water-heater has an end cover (5) fixed at two end positions of a shell (4) through a nut. The shell is formed as a hollow cylinder structure. A left side of the shell is connected with a water inlet pipe (1). A middle position of the water inlet pipe is connected with a water inlet valve (2). A right end of the shell is connected with a water outlet pipe (7). A water outlet valve (6) is connected with a middle position of the water outlet pipe. A lower part of the shell is connected with a mounting frame (9). An insulating layer is formed at a lower part of a heating pipe. A graphene radiator is electrically connected with a power plug (8). USE - Protection function featured graphene ultra-conducting water-heater. ADVANTAGE - The water-heater has better protection effect, so that the heater can be protected from impact damage through a protecting cover. The water-heater avoid the user caused by scald phenomenon due to large heater surface temperature, and utilizes graphene superconducting heating principle so as to heat water in continuous manner, so that user can be bathed in a continuous manner, thus satisfying requirement of the a water tank and increasing use performance of the water heater. DESCRIPTION OF DRAWING(S) - The drawing shows a side perspective view of a protection function featured graphene ultra-conducting water-heater.
