Electric hot water boiler capable of rapidly exchanging heat

According to the technical scheme, the quick heat exchange electric hot water boiler is characterized by comprising an electric hot water boiler body, two mounting holes are formed in the outer wall of the electric hot water boiler body, a water filling pipe is fixedly mounted in the mounting hole located in the lower position, and a backflow pipe is fixedly mounted in the mounting hole located in the upper position; water pumps are fixedly mounted in the water filling pipe and the return pipe respectively; the heat exchange assembly is arranged on one side of the water filling pipe and used for heat exchange, after the electric heating boiler body heats hot water, the heat exchange cavity is filled with high-temperature hot water through the water filling pipe, at the moment, cold water is filled into the heat exchange cavity through the cold water inlet, cold and heat exchange is conducted through the heat conduction plate, and the rapid heat exchange effect is achieved; heat preservation is conducted on th
