AI Technical Summary
Existing neck fans are heavy, uncomfortable to wear, lack adjustable airflow direction, and have limited application scenarios, failing to meet users' flexible needs.
A fan with stepless adjustable airflow has been designed. It can be flexibly clipped to collars, hat brims, backpack straps, or desktops using a clip. It uses a brushless motor and worm gear blades, combined with a flexible metal lever and gear ring to achieve 360° all-around airflow adjustment. Metal bushings and rubber rings ensure stability and quiet operation.
It improves wearing comfort and flexibility, achieves precise air delivery, expands usage scenarios, enhances user experience, and features stable structure, efficient operation, energy saving, and long lifespan.
