When the solar energy exchange When the hot temperature fails to reach the target temperature, the mercury in the mercury tube 61 and the temperature measuring bulb 62 expands less, and the sliding float 64 is far away from the proximity switch 67. At this time, the electric heating wire 32 starts to work to heat the water in the second water storage barrel 31. As the temperature rises, the mercury in the mercury tube 61 and the temperature measuring bulb 62 expands due to the heat, and then drives the sliding float 64 to slide in the sliding tube 63 through the buoyancy. When the sliding float 64 is close to the proximity switch 67, the proximity switch 67 controls the electric heating wire 32 to stop heating. When the upper limit of the temperature needs to be adjusted, by rotating the threaded rod 65, the sliding mounting plate 66 is driven to slide in the sliding tube 63 due to the threaded relationship, and then the height of the proximity switch 67 is adjusted, thereby adjusting the upper limit of the temperature.
