The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Please refer to Figures 1 to 4, a high-carbon molecule heating oil energy-saving electric water heater 100 includes a housing 10, an upper cover 11 and a lower cover 12, the housing 10 and the upper and lower cover 11 , 12 are combined into a main container 13, wherein the high-carbon molecule heating oil 20 is filled in the main container 13, and the heat exchange coil 30 that carries out heat exchange with the high-carbon molecule heating oil 20 is arranged in the main container 13, is located in the main The outer side of the container 13 is provided with a water inlet collecting pipe 40 and a water outlet collecting pipe 50, and the water inlet collecting pipe 40 and the water outlet collecting pipe 50 communicate with the heat exchange coil 30 in the main container 13 respectively; The high-carbon molecular heating oil 20 in the container 13 is inserted into the activation electrode 60 and the electric heating tube 70 for activating the high-carbon molecular heating oil and heating it to an appropriate temperature. A probe 14 for detecting the temperature of the high-carbon molecular heating oil 20 is inserted into the main container 13 along the upper cover plate 11, so as to directly reflect the working condition of the internal high-carbon molecular heating oil. The bottom of the main container 13 is provided with a sewage pipe 15 to clean and purify the inside of the main container. There is a water outlet 51 in the water outlet collecting pipe 50, and the user is supplied with hot water from the water outlet 51; The body 53 is provided with a water temperature gauge 54, and a temperature-adjusting water inlet 55 is installed at the bottom of the body 53, which is convenient for people to use.

The pressure relief device 80 includes a pressure relief tank 81 connected to the main container 13 by a connecting pipe 16 Through, the pressure relief box 81 is equipped with a cooling medium 82 that is incompatible with the high-carbon molecule heating oil 20 and has a high specific gravity, and a pressure switch 83 is installed on the upper part of the pressure relief box 81, and a pressure switch 83 controlled by a solenoid valve 84 is installed on the lower part. The sewage pipe 85 is provided with an exhaust pipe 88 controlled by a check valve 86 and a solenoid valve 87 on the side, and an overpressure exhaust pipe 89 is arranged between the upper cover plate 11 and the pressure relief box 81.
