In some embodiments, when the fan body 1 is manufactured by an integral molding process, the fitting opening 11 is directly opened at an end of the fan body 1.

The fitting opening 11 is circular in shape. However, the shape of the fitting port 11 is not limited thereto, and the shape of the fitting port 11 can be (not limited to): polygonal, oval, racetrack, etc.

The flexible connection unit 2 is made of soft rubber, silicone rubber or fluorine rubber.

The light emitting element 3 can be (without limitation): LED lamp beads 31, spherical bulbs, laser generators, purple light lamps or colored lamps and other devices.

In the above embodiment, the fan body 1 is provided with the fitting opening 11, the fitting opening 11 is connected to the flexible connector 2, the flexible connector 2 is provided with the light source hole 21, and the light emitting element 3 is disposed in the light source hole 21.

The inside of fan main part 1 is provided with locating part 5, and the mutual butt between locating part 5 and the light emitting component 3, after light emitting component 3 received outside pressing force, the locating part 5 can give light emitting component 3 holding power, avoids light emitting component 3 to appear returning or drop the inside problem of fan main part 1 from light source hole 21. Meanwhile, the light-emitting element 3 cannot be retracted due to the support of the limiting piece 5, and the flexible connecting piece 2 is tightly attached, so that gaps are difficult to appear between the light-emitting element 3 and the light source hole 21, external dust and foreign matters are effectively prevented from entering the fan main body 1, and the cleaning in the fan main body 1 is ensured.

The assembly port 11 is internally provided with a clamping ring 14, the flexible connecting piece 2 is provided with a clamping groove 22, and the flexible connecting piece 2 is connected with the clamping ring 14 through the clamping groove 22.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a flexible connecting member according to the present embodiment.

As shown in fig. 3, the flexible connecting piece 2 is provided with a clamping groove 22, and the clamping groove 22 is matched and clamped with the clamping ring 14 on the assembly port 11. After the clamping groove 22 and the clamping ring 14 are matched and clamped, the connection between the flexible connecting piece 2 and the assembly port 11 is more compact, and when external force acts on the flexible connecting piece 2, the flexible connecting piece 2 is not easy to fall off. Therefore, the provision of the snap ring 14 and the snap groove 22 can enhance the connection strength and stability between the flexible connection member 2 and the fan main body 1.

However, the shapes of the first and second connection members 23 and 24 are not limited thereto, and the shapes of the first and second connection members 23 and 24 can be changed as the shape of the fan main body 1 is changed. For example, when the fan main body 1 is rectangular in shape, the first and second connection members 23 and 24 can be square in shape.

When an external force acts on the first connecting member 23 by pulling, the flexible connecting member 2 is easily deformed and pulled out of the fitting opening 11 by the external force. The volume of the second connecting piece 24 is larger than that of the first connecting piece 23, the second connecting piece 24 is arranged inside the fan main body 1, when a large pulling force is encountered, the second connecting piece 24 is large, and is difficult to compress to a size suitable for entering and exiting the assembly opening 11, so that the flexible connecting piece 2 is prevented from being pulled out.
