Abstract:
The present invention belongs to the field of super-large ceiling fans, and particularly relates to a ceiling fan device having an anti-falling structure. The device comprises a ceiling fan main body, and three or more fan blades which are all arranged on the ceiling fan main body. The device further comprises a plurality of interlocking rings, which are sequentially arranged around an outer side of the ceiling fan main body from far to near, wherein three or more mounting nodes are arranged on the interlocking rings, and are respectively connected to the three or more fan blades. In the device, by using the characteristic that individual fan blades are broken and fall while the other fan blades are intact, the three or more fan blades are interlocked and interconnected by means of the plurality of interlocking rings, such that when some fan blades are broken, regardless of the broken part or the cause of breaking, the other intact fan blades can suspend the broken fan blades in air, thereby making the entire device form an interlocked and interconnected anti-falling structure, and thus comprehensively protecting people and apparatuses below the device.
