[0026] In this embodiment: the heat collecting device includes a support frame 101, a fixing seat 102 is arranged on the front side of the support frame 101, ten heat collecting tubes 103 are evenly arranged on the fixing seat 102, a heat collecting box 104 is arranged on the top of the ten heat collecting tubes 103, a mounting plate 105 is arranged at the lower rear side of the heat collecting box 104, the angle between the heat collecting tube 103 and the horizontal plane is forty-five degrees, the support frame 101 supports the heat collecting tube 103 through the fixing seat 102 to collect solar energy to heat the water inside, and transfers the heat to the heat collecting box 104 through the water, and the mounting plate 105 is used to fix the transfer device;

[0027] In this embodiment, the transfer device includes a hot water tank 201, a water outlet pipe 202 is provided at one side of the bottom of the hot water tank 201, a connecting frame 203 is provided on the hot water tank 201, a transfer box 204 is provided on the connecting frame 203, a fixed edge 205 is provided on the front side of the transfer box 204, a connecting pipe 206 is installed between the transfer box 204 and the hot water tank 201, a temperature control valve 207 is installed on the connecting pipe 206, the connecting pipe 206 is sealed and connected to the hot water tank 201, and the connecting pipe 206 is connected to the transfer The heat collecting box 104 is sealed and connected to the transfer box 204, and the heat collecting box 104 is connected to the transfer box 204 through the fixed edge 205, so that the heat collecting pipe 103, the heat collecting box 104 and the transfer box 204 are connected. When in use, the heat collecting pipe 103 heats the water in the transfer box 204 supported by the connecting frame 203. When the water in the transfer box 204 reaches the set temperature, the temperature control valve 207 opens, so that the hot water in the transfer box 204 flows into the hot water tank 201 through the connecting pipe 206 and is taken out through the water outlet pipe 202;

[0028] In this embodiment: the water replenishment device includes a cold water tank 301, a water suction pipe 302 is arranged on one side of the cold water tank 301, a water inlet pipe 303 is arranged on the side of the cold water tank 301 away from the water suction pipe 302, and a ventilation pipe 304 is arranged behind the water inlet pipe 303. The two ends of the water suction pipe 302 extend into the bottom of the cold water tank 301 and the top of the transfer box 204 respectively. The water suction pipe 302 and the connecting pipe 206 are far away from each other and are respectively located on both sides of the transfer box 204. When the water amount in the transfer box 204 decreases, the water in the cold water tank 301 will be sucked through the water suction pipe 302 to realize automatic water replenishment. The ventilation pipe 304 ensures that the water can be sucked smoothly during replenishment.

At the same time, the water suction pipe 302 and the connecting pipe 206 are away from each other, which slows down the cooling speed at the temperature control valve 207 and ensures that as much hot water as possible can enter the hot water tank 201; when the water in the cold water tank 301 is used up, cold water is added to it through the water inlet pipe 303, and the air permeable pipe 304 ensures that water can be absorbed smoothly during replenishment.
