When the water temperature in the water outlet pipe 22 is higher than the target water temperature, the lower limit regulating mechanism 05 is used to adjust the temperature of the solar heating mechanism 01. The temperature of the water in the water outlet pipe 22 causes the mercury to expand, and then the buoyancy drives the buoyancy plate 46 to slide upward in the expansion slide 43, so that the buoyancy plate 46 is close to the second proximity switch 63, and then the second water pump 27 is controlled by the second proximity switch 63 to allow cold water to enter the second water storage tank 23 through the water inlet pipe 24, thereby adjusting the water temperature to the target water temperature, and by rotating the threaded rod 62, the top plate 61 is driven to slide in the buoyancy plate 46 due to the threaded relationship, thereby adjusting the upper limit of the water temperature.

When water is needed, the water in the first water tank 11 enters the second water tank 23 through the water outlet pipe 22 by opening the first water pump 21, thereby completing the use of the water. When the water temperature in the water outlet pipe 22 does not reach the target water temperature, the buoyancy plate 46 slides downward in the expansion slide 43. When the lower limit of the water temperature is reached, the second magnetic block 58 and the first magnetic block 56 are magnetically attracted, thereby causing the sliding mounting plate 54 to slide in the sliding plate 52, and the spring 55 is stretched. When the sliding mounting plate 54 slides to the bottom of the first proximity switch 57, the first proximity switch 57 is triggered. The output signal controls the electric heating wire 32 to heat the water temperature in the second water tank 23 to reach the target water temperature. The sliding plate 52 slides on the sliding frame 51, and the sliding plate 52 is fixed by the fixing bolt 53, so as to adjust the lower limit of the water temperature. When the water temperature in the water outlet pipe 22 is higher than the target water temperature, the mercury expands due to the temperature of the water in the water outlet pipe 22, and then the buoyancy drives the buoyancy plate 46 to slide upward in the expansion slide 43, so that the buoyancy plate 46 is close to the second proximity switch 63, and then the second water pump 27 is controlled by the second proximity switch 63 to allow cold water to enter the second water tank 23 through the water inlet pipe 24, so as to adjust the water temperature to the target water temperature.
