Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0023] In the description of the utility model, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

[0026] See also Figure 1-5 , the utility model provides a technical solution:

[0027] A photovoltaic water heater for preventing overheating comprises a heat-insulating shell 1, a hot water outlet 6 and an overflow structure 10. A mounting cover 2 is arranged on the outer side of the heat-insulating shell 1, a reinforcing spiral sleeve 3 is fixedly connected to the outer side of the mounting cover 2, an inner tank 5 is arranged on the inner side of the heat-insulating shell 1, a stainless steel bellows 7 is connected to the outer side of the hot water outlet 6, the other end of the stainless steel bellows 7 is connected to a cold water inlet 8, the outer side of the cold water inlet 8 is connected to a water replenishment structure 9, a mounting column 11 is spirally connected to the inner side of the mounting cover 2, a controller 12 is installed on the outer side of the mounting column 11, a heating pipe 13 is connected to the side of the controller 12 away from the mounting column 11, a temperature measuring probe 14 is installed on the inner side of the inner tank 5, and a control instrument panel 15 is installed on the outer side of the heat-insulating shell 1.

[0028] The water replenishment structure 9 is composed of a water replenishment ball valve 901 and a corrugated connecting pipe 902. The two ends of the corrugated connecting pipe 902 are connected to the cold water inlet 8 and the overflow structure 10 respectively. This arrangement allows the heat storage water to be replenished through the water replenishment structure 9. The water replenishment ball valve 901 and the corrugated connecting pipe 902 cooperate with each other. When the water is full, it is discharged from the outlet of the overflow structure 10. The water outflow from the overflow port proves that the water in the hot water storage tank is full, and then the water replenishment ball valve 901 is manually closed; the reinforcement spiral sleeve 3 is spirally connected to the heat insulation shell 1. There are two reinforcement spiral sleeves 3 in total. The reinforcement spiral sleeves 3 are symmetrically set on both sides of the inner tank 5. This The arrangement makes it easy to install and disassemble the reinforcing spiral sleeve 3, that is, to install and disassemble the mounting cover 2; the outer side of the reinforcing spiral sleeve 3 is sleeved with a sealing sleeve 4, and the sealing sleeve 4 fits against the inner wall of the heat-insulating outer shell 1. This arrangement enables the sealing sleeve 4 to enhance the sealing effect between the mounting cover 2 and the heat-insulating outer shell 1; the mounting column 11 passes through the mounting cover 2, the heating tube 13 passes through the reinforcing spiral sleeve 3 and the inner tank 5, and there are two controllers 12. This arrangement enables the controller 12 and the heating tube 13 to be installed through the mounting column 11, so that the heating tube 13 can exert a heating effect.

[0029] Working process: The inner tank 5 of the water tank is a thin-walled structure made of stainless steel, and is designed to store heat without pressure. Cold water enters the stainless steel bellows 7 from the cold water inlet 8, and heat is exchanged through the stainless steel bellows 7. Then hot water flows out from the hot water outlet 6. The flowing water is healthy for drinking, and the stainless steel bellows 7 is under pressure. The water used for heat storage is replenished through the water replenishment structure 9. The water replenishment ball valve 901 and the corrugated connecting pipe 902 cooperate with each other. When the water is full, it is discharged from the outlet of the overflow structure 10. The water out of the overflow port proves that the water in the hot water storage tank is full. Then the water replenishment ball valve 901 is manually closed. The heating tube 13 is heated by direct current, and no inverter is required. It is directly supplied by the photovoltaic power generation panel. The required temperature of 15 is adjusted by the control panel. When the temperature probe 14 detects that the temperature of the water used is overtemperature , the controller 12 turns off the heating function of the heating tube 13 to prevent ultra-high temperature. Because the water used for heat storage is always the same, the amount of scale generated is very small, and the amount of water replenished in the later stage is not large, so there is no scale and the water is cleaner. At the same time, because the heating tube 13 is heated by direct current, it is not easy to generate scale on its surface, the heat transfer efficiency is higher, and the electric heating failure rate is low; the installation cover 2 is positioned by reinforcing the spiral connection between the spiral sleeve 3 and the insulating shell 1, and the sealing sleeve 4 enhances the sealing effect between the installation cover 2 and the insulating shell 1. When the photovoltaic water heater is to be repaired or cleaned, the reinforcing spiral sleeve 3 and the installation cover 2 are rotated, so that the installation cover 2 is convenient to be separated from the insulating shell 1, and the outer side of the installation column 11 is provided with a thread, so that the installation column 11 is convenient to be installed on the installation cover 2.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
