The rotation of the pump body motor 214 drives the rotating blades 215 to rotate. The rotation of the rotating blades 215 draws the water in the water tank 301 into the suction inner cavity 219 through the water outlet pipe 307 and the suction pipe 217. Then, the centrifugal force generated by the rotation of the rotating blades 215 drives the water into the extraction inner cavity 218. Then, the water enters the heat absorption tube 209 through the extraction tube 216, the water inlet 222, the inner connecting tube 224 and the inner tube 210, absorbs heat in the heat absorption tube 209, and finally, the water after absorbing heat returns to the water tank 301 through the inner tube 210, the inner connecting tube 224, the water outlet 223 and the return pipe 306.When hot water is needed, cold water is injected through the water inlet pipe 309. Since the entire pipeline is in a closed state, the hot water will be squeezed out from the hot water outlet pipe 308. When the water in the water tank 301 boils, water vapor will be generated, thereby pushing the lifting plate 321 and the lifting column 319 to rise, thereby driving the lifting block 317 to rise along the fixed column 318, thereby driving the long groove rod 316 to rise, and through the cooperation of the long groove of the long groove rod 316 and the small sliding column 315, the rotating block 314 is driven to rotate, thereby driving the rotating shaft 324 and the outer gear 313 to rotate, thereby driving the small gear 322 and the inner gear 312 to rotate, thereby driving the docking gear 311 and the gear shaft 310 to rotate, thereby driving the fixed rack 305 and the heat dissipation door plate 303 to rise, the opening spring 304 is compressed, and the heat dissipation door plate 303 is opened to dissipate heat to the outside.
