With the increasing benefits of greenhouse, the average outdoor temperature in summer can reach 35 C. Electric energy driven fans and air conditioning have become the most important cooling tools. With the continuous strengthening of people's awareness of green environmental protection, green environmental protection has become a specific trend in the production of products. Our company has designed this product based on this concept. First of all, we use solar energy to generate electricity. Solar energy is a clean, green, large reserves, clean and environmentally friendly renewable resources, which fully conforms to the concept of green environmental protection. The designer combines the flexible solar charging board with the umbrella with a fan to drive the small fan in the umbrella to work. The electric energy can be stored in the lithium battery. After voltage conversion, it can charge the mobile phone and other electronic products. It can also supply power to the fan when the sunlight is insufficient. The solar fan umbrella adopts a light folding structure similar to the original solar umbrella in structure; it has better cooling effect than the ordinary portable cooling tool in function; and it uses solar energy in technology, which not only achieves energy saving and environmental protection, but also has the sun shading function of the general umbrella. Batteries can also charge mobile phones and other electronic products through USB interface, and the umbrella structure and weight remain basically unchanged, maintaining the unity of the umbrella. In the case of energy crisis, solar fan umbrella makes use of renewable and environmentally friendly energy, reduces environmental pollution, facilitates outdoor charging of mobile phones and other electronic products, adds a comfort to people. It can be said that it conforms to the requirements of the times and the environment, creates technological innovation of umbrellas, makes our living tools more environme
