Abstract
Description
Technical Field
[0001] This utility model relates to the field of fan blade technology, and in particular to a concealed stacked fan. Background Technology
[0002] Traditional folding fans generally employ an exposed fan rib connection structure during design and manufacturing. This structure is characterized by key connecting components, such as rivets and hinges, being directly exposed on the outer side of the fan surface. While this design is simple and easy to implement, it severely impacts the product's aesthetic integrity. The exposed connecting components significantly detract from the overall beauty of the fan surface, giving it an appearance that is neither refined nor harmonious.
[0003] Furthermore, in existing folding fan structures, adjacent fan blades are typically fixed by direct stacking. This method of fixing easily generates significant frictional resistance during the opening and closing of the fan. This frictional resistance not only makes it difficult to precisely control the fan's unfolding angle but can also cause misalignment of the fan surface during opening and closing. Consequently, it becomes difficult to maintain a uniform opening and closing motion of the fan blades, resulting in an uneven fan surface. This uneven opening and closing not only affects the user experience but also makes the fan blades appear less aesthetically pleasing, further reducing the overall aesthetics and user satisfaction of the product. Utility Model Content
