▎ 摘　　要

NOVELTY - The pipe has a water pipe main body (1) whose end is provided with a water outlet (2) that is provided with a switch (6). An outer wall surface of the water pipe main body is covered with an insulating layer (7), a graphene conductive film (3) and a heat protection material (4) along inner to outer direction. The water pipe main body is provided with a temperature controller (5). The graphene conductive film is connected with the temperature controller that is connected with an external power source. USE - Hot water pipe. ADVANTAGE - The pipe is reasonable in structural design and inexpensive, and has prolonged service life, and utilizes graphene with high conductivity material so as to heat water of the water pipe main body in a rapid manner, reduces power consumption, and increases popularization value. DETAILED DESCRIPTION - The heat protective material is a thermal insulation film. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a hot water pipe.
