Document Type and Number:
WIPO Patent Application WO/2022/001776
Kind Code:
A1
Abstract:
An invisible fan comprises a turntable (100), a plurality of fan blades (200) and a synchronization mechanism (300). The synchronization mechanism (300) comprises a rotating ring (310) and a plurality of connecting rods (320), wherein the rotating ring (310) is mounted to the turntable (100), and the rotating ring (310) can rotate relative to the turntable (100) around the central axis of the turntable (100). The fan blade (200) has a mounting end and a free end, the mounting end has a mounting portion (210) and a connecting portion (220) spaced apart from each other, the mounting portion (210) is mounted to the turntable (100) by means of a first rotary connecting portion (400), a first end of the connecting rod (320) is mounted to the rotating ring (310) by means of a second rotary connecting portion (500), a second end of the connecting rod (320) is mounted to the connecting portion (220) by means of a third rotary connecting portion (600), and the fan blade (200) can rotate about the central axis of the first rotary connecting portion (400). The fan blades are connected to one another by the synchronization mechanism, so that the fan blades can be unfolded or stored synchronously. For invisible fans of different sizes, only the dimension of the connecting rod needs to be changed, so that the same rotating ring can be adapted to invisible fans of different sizes, the design cost and the manufacturing cost of the invisible fan are reduced, and subsequent maintenance of the invisible fan is facilitated.
