Abstract

The invention relates to a fan with fan blades capable of being synchronously stored and expanded. The fan comprises a fan head and the fan blades, the multiple fan blades are evenly arranged on the periphery of the fan head, and the fan blades and the fan head are rotatably connected. Return torsional springs for storing the fan blades are arranged on rotating shafts of the fan blades and the fanhead, synchronous gears are arranged at the connecting ends of the fan blades and the fan head, and the synchronous gears and the rotating shafts of the fan blades are coaxially arranged. A synchronous gear ring rotatably connected with the fan head is arranged on the fan head, the synchronous gear ring and all the synchronous gears are tangent and are engaged, and the rotating center of the synchronous gear ring coincides with the rotating center of the fan head. According to the fan, the fan blades can be synchronously stored and expanded, the manufacturing process requirement is low, reliability is high, and cleaning is convenient.

Description

technical field [0001] The invention relates to a daily product, in particular to a fan. Background technique [0002] Nowadays, people's aesthetic requirements for interior decoration are getting higher and higher. Traditional ceiling fans are always in a straight state no matter they are rotating or stationary, giving people a rigid and dull mechanical feeling, which does not meet people's aesthetic requirements. And traditional ceiling fans still take up a lot of indoor space when not in use. [0003] A prior art with a publication number of CN201620002118, which is composed of a fan blade storage structure with lights, which includes a fan main unit and a lighting lamp arranged below it. It is connected with the lighting lamp, and it is characterized in that: the outer circumference of the fan main body is evenly distributed with several connecting plates, and the end of the connecting plate is connected to the fan blade through the receiver; wherein the receiver includ...
