[0002] In traditional folding fan designs, the blades are typically made of paper, while the ribs are often made of bamboo or wood. While these materials are lightweight and aesthetically pleasing, they present significant limitations in practical use. First, paper blades are easily damaged by moisture or oil, shortening the fan's lifespan. Second, bamboo or wooden ribs lack strength and durability, and are prone to deformation or damage, especially in humid environments. Furthermore, when folded, the blades of traditional folding fans are prone to wrinkling due to the structural limitations of the ribs, compromising the fan's aesthetics and portability.

[0003] To overcome these issues, some improved folding fans have appeared on the market, attempting to improve their performance by using different materials or structural designs. However, these improvements often focus on a single performance improvement, without considering the overall performance and user experience of the folding fan. Utility Model Content
