the transparent mark is adhered to the top surface of the hub and covers the perspective groove, and the transparent mark and the fan blade assembly rotate synchronously;
the optical assembly is arranged between the hub and the stator assembly, and when the fan blade assembly rotates, the optical assembly emits light and forms a time light tunnel effect, and the time light tunnel effect is displayed through a perspective surface formed by the perspective groove.
23. The fan as recited in claim 22, wherein said light assembly comprises:
the light-emitting piece is sleeved on the hollow shaft;
the light guide piece is sleeved on the hollow shaft and is positioned above the light emitting piece;
the light guide part guides the light emitted by the light emitting part to the top surface of the hub to form the time light tunnel effect.
24. The fan of claim 23, wherein the light guide comprises:
the top part is provided with a through hole, and the hollow shaft is positioned in the through hole;
a ring side connected to an outer edge of the top.
25. The fan as claimed in claim 24, wherein a bottom surface of the side portion of the ring is provided as a light guide surface, and a light emitting body is convexly provided on the top portion along a circumference of the through hole, the light guide surface guiding the light to the light emitting body so that the light emitting body emits the light.
26. The fan as claimed in claim 25, wherein the light emitting member has a plurality of beads thereon, and the side portion of the ring has a bottom surface defining an annular groove, the annular groove being aligned with the plurality of beads, and an inner surface of the annular groove being the light guiding surface.
