Abstract
Description
Technical Field

[0025] like Figure 1 and 2 As shown, the utility model provides a circulating heating electric boiler, comprising a heat-insulating shell 1:

Two pressure relief valves 7 are respectively provided on the upper ends of the thermal insulation chamber 8 and the heating chamber 9; two water outlet pipes 5 are respectively fixedly provided on the lower end of one side of the thermal insulation shell 1, and the two water outlet pipes 5 are respectively connected to the thermal insulation chamber 8 and the heating chamber 9; two water inlet pipes 6 are respectively fixedly provided on the upper end of one side of the thermal insulation shell 1, and the two water inlet pipes 6 are respectively connected to the thermal insulation chamber 8 and the heating chamber 9; a generator 11 is fixedly provided on one side of the thermal insulation shell 1 through a bracket.
[0027] In order to utilize steam for energy recovery and realize steam power generation, a steam power generation device 2 capable of utilizing steam for power generation is provided on the outer surface of the heat-insulating shell 1 for recovering steam;
[0028] like Figure 3 As shown, the steam power generation device 2 includes an air guide pipe 21, which is fixedly arranged at the upper end of the heating chamber 9, a circulating cylinder 22 is fixedly arranged at the lower end of the air guide pipe 21, an exhaust hole 24 is opened on one side of the circulating cylinder 22, a piston 23 is movably arranged inside the circulating cylinder 22, the bottom end of the piston 23 penetrates the lower end of the circulating cylinder 22, a movable connecting rod 25 is movably arranged at the bottom end of the piston 23, a turntable 26 is fixedly arranged at the input end of the generator 11, the lower end of the movable connecting rod 25 is rotatably connected to one side of the turntable 26, the output end of the generator 11 is connected to the input end of a micro transformer 27 through a wire, the output end of the micro transformer 27 is connected to the input end of a heating generator 28 through a wire, and the micro transformer 27 is connected to the heating generator 28. They are respectively fixedly connected to one side of the heat-insulating outer shell 1. After being heated by the hot water in the heating chamber 9, the water vapor is transmitted to the circulating cylinder 22 by the air duct 21 at the upper end of the heating chamber 9, thereby pushing the piston 23. When the piston 23 moves to the lowermost end of the circulating cylinder 22, part of the steam will be discharged from the exhaust hole 24, resulting in a lower pressure in the circulating cylinder 22. Then, by utilizing the inertia of the turntable 26, the movable connecting rod 25 pushes the piston 23 to reset it, thereby achieving the effect of circular movement. The circularly moving piston 23 drives the movable connecting rod 25 and the turntable 26 to operate, thereby realizing the power generation effect of the generator 11. The generated current is changed in voltage by the micro-transformer 27, thereby realizing steam power generation.
[0029] Furthermore, in order to enable the heating chamber 9 to perform cyclic heating, a heating and heat preservation device 3 capable of heating and heat preservation of the heating chamber 9 is provided inside the heat preservation chamber 8, and is used to perform cyclic heating of the heating chamber 9;
[0030] like Figure 4As shown, the heating and heat preservation device 3 includes a heat-conducting end 31, an output end of the heating generator 28 passes through one side of the heat-preserving shell 1, and the output end of the heating generator 28 is fixedly connected to one side of the heat-conducting end 31. A heat-conducting pipe 32 is fixedly provided at the output end of the heat-conducting end 31. The heat-conducting pipe 32 is located at the lower end of the inner side of the heat-preserving cavity 8. The current generated by the generator 11 flows from the micro-transformer 27 into the heating generator 28, thereby driving the heating generator 28 to generate heat. The generated heat energy is introduced from the heat-conducting end 31 into the heat-conducting pipe 32. Since the heat-conducting pipe 32 is distributed throughout the lower end of the heat-preserving cavity 8, the water in the heat-preserving cavity 8 is heated, thereby improving the heating speed of the heating cavity 9 and reducing the power loss required for continuous heat preservation.
[0031] The working principle is as follows: when the utility model is in use, the two pressure relief valves 7 are opened, and water is poured from the two water inlet pipes 6 into the insulation chamber 8 and the heating chamber 9 respectively. After the filling is completed, the pressure relief valve 7 at the upper end of the heating chamber 9 is closed, thereby starting the resistance heater 10 to heat the water in the heating chamber 9. The steam generated by the heating is used by the steam power generation device 2 to generate electricity, and the generated current is used to power the heating and heat preservation device 3 so that it can heat the water in the insulation chamber 8, thereby increasing the water temperature in the insulation chamber 8. The temperature of the heated insulation chamber 8 can keep the hot water in the heating chamber 9 warm. When the water temperature in the heating chamber 9 is insufficient, the speed of increasing the water temperature in the heating chamber 9 can also be accelerated.
