INTEGRATED FOLDING SMALL FAN

FIELD OF THE INVENTION

[0001] The present invention belongs to the technical field of a hand-held fan, and in particular to an integrated folding small fan.

BACKGROUND OF THE INVENTION

[0002] With the climate warming, the improvement of living standards and the improvement of people's requirements for the comfort of living and working environments, fans, as commonly used cooling equipment, are widely used day by day. More particularly in offices, families and trips, hand-held small fans are favored by more and more consumers because of portability and practicality thereof. Many users use the hand-held small fans in public places such as buses, subways, shopping malls, etc., so as to realize a cooling requirement anytime and anywhere, which not only meets a practical function, but also takes into account a beautiful and decent appearance.

[0003] However, there are some shortcomings in existing folding small fans on the market. First of all, in the design of many traditional folding fans, a fan blade part is separated from a handle part, which leads to a complex overall structure and a great difference in shape, thus affecting the aesthetics and portability of a product. Secondly, due to the separation design of the fan blade and the handle, an overall volume is often large, which is not conducive to storage and carrying, especially in the case of a limited space, a user is easy to feel inconvenient when carrying and storing. In addition, an existing folding mechanism mostly adopts a simple hinge or connector, lacking a stable limit design, which leads to a situation that the fan blades are prone to shake or have unstable angles during use, thus affecting the use experience.

[0004] In view of the above problems, a new type of folding small fan with a compact structure and an integrated design is urgently needed to solve the shortcomings of the existing product in portability, storage and use stability.
