Description

Technical Field

[0001] The present invention relates to the technical field of wind power charging treasures, and particularly to a multi-scenario wind power charging treasure for convenience. Background Art

[0002] Wind power generation is a clean energy generation method that uses wind power to drive the rotor of a wind power generation unit to rotate, and then converts wind energy into electrical energy. A device that provides electrical energy for various portable electronic devices uses wind power to drive an internal generator to generate electricity and stores the generated electrical energy in an internal lithium-ion battery. When charging an electronic device is needed, the wind power charging treasure can, like a traditional charging treasure, provide electrical energy for the device through output ports such as a USB interface.

[0003] Existing wind power charging treasures may not perfectly integrate wind power generation, energy storage, and portability, resulting in a large device volume and heavy weight, which is not convenient for carrying. Also, the existing blades are not easy to disassemble and store when not in use, resulting in inconvenient storage and a large occupied space.

[0004] For example, a wind power charging device disclosed in the patent with the publication number CN107476939A. In this patent, the fan blades of the device cannot be disassembled from the cylindrical housing. This means that when not in use, the fan blades will occupy a large space, which is not only inconvenient for storage and carrying, but also increases the storage burden on users, reduces the practicality and user experience of the product. At the same time, the non-detachable fan blades may also increase the risk of damage during transportation, thereby limiting the user's flexibility in outdoor or mobile scenarios and reducing the portability and market competitiveness of the product.

[0005] Therefore, it is necessary to invent a multi-scenario wind power charging treasure for convenience to solve the above problems. Summary of the Invention
