[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 5In an embodiment of the utility model, a solar water heater with good heat collection effect includes a support frame 1, a water tank 2 is installed on the high top of the support frame 1, and a vacuum heat collection tube 3 is installed in the inner cavity of the water tank 2 and penetrates to the outside of the water tank 2. A connecting frame 4 is installed at the bottom end of the two oblique rods of the support frame 1, and a reflective unit 5 is detachably connected to the interior of the connecting frame 4 through a connecting mechanism. The connecting frame 4 has a circular frame structure; the reflective unit 5 includes an aluminum reflector 501, a support plate 502 and a bottom plate 503; the aluminum reflector 501 is located above the support plate 502, and the bottom plate 503 is located above the support plate 502. The top of the bottom plate 503 is bent upward to pass over the support plate 502 and cover the four sides of the top of the aluminum reflector 501 to form a edging.

[0021] In this embodiment, since the vacuum heat collecting tube 3 is composed of an inner tube and an outer tube, a vacuum state is formed between the inner tube and the outer tube, and the surface of the inner tube has a spectral absorption coating (such as copper oxide coating or black copper coating), when sunlight directly shines on the vacuum heat collecting tube 3, when photons hit the coating, the solar energy is converted into heat energy and heat exchange occurs with the water in the inner tube, thereby achieving solar heating of the water. After being heated, the density of the water decreases and moves upward into the water tank 2, while the water in the water tank 2 enters the inner tube, achieving the effect of always having hot water in the water tank 2.

[0022] The sunlight passing through the vacuum heat collecting tubes 3 is refracted by the aluminum reflector 501 after passing through the vacuum heat collecting tubes 3. The refracted light is irradiated on the lower outer wall of the vacuum heat collecting tubes 3, thereby improving the utilization rate of sunlight and increasing the collision area between photons and the vacuum heat collecting tubes 3, thereby further improving the conversion efficiency of solar energy.

[0023] The support plate 502 (made of foam board) at the bottom of the aluminum reflector 501 is made of a lighter material that can provide effective support and reduce the overall weight of the reflective unit 5. The bottom plate 503 can fix the aluminum reflector 501 and the support plate 502 together through the bent edges of its edges, making them a whole.

[0024] Please refer to Figure 4 The connecting mechanism includes a strip groove 10 opened on one side of the connecting frame 4 and penetrating into the inner cavity of the connecting frame 4, and a slot 9 opened on the inner side of one side of the connecting frame 4. The reflective unit 5 passes through the strip groove 10 and is plugged into the slot 9.

[0025] In this embodiment, when installing the reflective unit 5, one end of the reflective unit 5 is aligned with the strip groove 10, and then the reflective unit 5 is pushed and inserted from the strip groove 10. As the reflective unit 5 is pushed in, one end of the reflective unit 5 is inserted into the slot 9, and the insertion of the reflective unit 5 is completed. At this time, the slot 9 and the strip groove 10 form a support for the reflective unit 5.

[0026] Please refer to Figure 2 and Figure 3 The end of the reflective unit 5 that has been plugged in and is located outside the connecting frame 4 is fixedly connected to the docking frame 6. The end of the docking frame 6 away from the reflective unit 5 is integrally formed with a handle 7. A through hole 8 is opened inside the docking frame 6. A screw hole is opened inside the connecting frame 4 at a position aligned with the through hole 8. The bolt passes through the through hole 8 and is threadedly connected to the screw hole.

[0027] In this embodiment: after the reflective unit 5 is plugged in, a bolt is passed through the through hole 8 and threadedly connected to the screw hole, and the bolt is tightened to fix the reflective unit 5. As the use time increases, when more impurities accumulate on the top of the aluminum reflector 501 of the reflective unit 5 and it cannot reflect light effectively, the bolt can be loosened and removed. At this time, the handle 7 can be pulled to drive the reflective unit 5 to move outward, and the reflective unit 5 can be pulled out and cleaned. In this way, the problem of the reflective unit 5 not being able to play its role due to the docking of impurities can be avoided.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
