[0017] Compared with the prior art, the present invention provides a solar water heater with a self-cleaning function, which has the following beneficial effects: 1. The solar water heater with self-cleaning function can efficiently achieve the goal of deep cleaning of the vacuum collector tube by using a special cleaning sponge to perform a detailed and in-depth wiping operation on the surface of the vacuum collector tube. This cleaning process is not only a simple removal of dirt on the surface of the collector tube, but also has important significance for improving the overall performance of the solar water heater, extending its service life, ensuring pure water quality without impurities, enhancing the stability of system operation, and promoting energy conservation and environmental protection. Specifically, deep cleaning of the vacuum collector tube can significantly improve the thermal efficiency of the solar water heater. As the core component of the water heater, if dust, scale and other impurities accumulate on the surface of the collector tube, it will seriously affect the absorption and conversion of heat, thereby reducing the heating capacity of the water heater. Through professional cleaning treatment, these obstacles can be effectively removed, so that the collector tube can restore good heat absorption performance, thereby improving the hot water output and heating speed of the water heater. In addition, regular cleaning of the vacuum collector tube can effectively extend the service life of the solar water heater. By improving the thermal efficiency and service life of the water heater, it can reduce energy waste and environmental pollution, and contribute to the sustainable development of society. Therefore, we should attach importance to the cleaning and maintenance of the vacuum collector tubes, and regularly use professional cleaning methods and tools for cleaning to ensure the good performance and long-term stable operation of the solar water heater.

[0018] 2. The solar water heater with self-cleaning function can efficiently guide the water resources inside the box to the nozzle position through the carefully designed first connecting pipe by means of its powerful power, and spray it evenly from the nozzle with appropriate pressure and flow rate by starting the pump body device, and effectively remove the loose dirt, dust and some stubborn stains attached to the outer wall of the collector tube, laying a solid foundation for the subsequent more in-depth cleaning work. In actual operation, full attention should be paid to and reasonable use of the initial cleaning link after the pump body is started, and the uniform distribution and coverage area of ​​the water flow can be ensured by accurately controlling the operating parameters of the pump body, such as flow rate, pressure, etc., and optimizing the layout design of the connecting pipes and nozzles, so as to maximize the effectiveness of the initial cleaning, create favorable conditions for the subsequent deep cleaning, and jointly promote the efficient and high-quality completion of the cleaning work of the vacuum collector tube.

[0019] 3. The solar water heater with self-cleaning function has brought great convenience to the maintenance and management of key components inside the solar water heater through the clever design and installation of a bracket system that is easy to operate, install and disassemble. Once the internal components of the solar water heater, such as the heating element, control system or vacuum collector tube, show performance degradation or damage, maintenance personnel can quickly and conveniently use these carefully designed brackets to safely and efficiently perform disassembly and replacement operations. This bracket design not only greatly saves the time required for maintenance, reduces the inconvenience and losses caused by downtime maintenance, but also significantly improves the efficiency and quality of maintenance work. The easy-to-disassemble feature of the bracket ensures that maintenance personnel can directly access and handle faulty components without complicated disassembly work, thereby speeding up maintenance progress and reducing maintenance costs.
