[0137] Please refer to Figures 7 to 9 , Figure 7 is Figure 3 a partial enlarged schematic view; Figure 8 isFigure 1 a partial plan view of the fan of the present application; Figure 9 a partial plan view of the fan of the present application; Figure 8 a partial plan view of the fan of the present application; Figures 7 to 9 The fan of the present application is described in detail as follows. Figures 7 to 9 As shown in FIG. 1, when the fan blade 122 is not rotating, the user will see the pattern on the hub 121 and the perspective slot C1 or the transparent material. When the fan blade 122 rotates in the direction A, part of the light rays L1 emitted from the second light emitting surface T1 will directly penetrate through the second mirror 134 and be emitted from the perspective slot C1 of the hub 121. Because the fan blade 122 rotates at a very fast speed, the viewer will have a visual persistence effect, and part of the light rays L1 emitted from the second light emitting surface T1 will form a hexagonal optical pattern P1 on the top surface S2 of the hub 121. In addition, the remaining part of the light rays L2, L3, L4 emitted from the second light emitting surface T1 will first be reflected between the second mirror 134 and the first mirror 132, and then penetrate through the second mirror 134 and be emitted from the perspective slot C1 of the hub 121. Because the fan blade 122 rotates at a very fast speed, the viewer will have a visual persistence effect, and the part of the light rays L2, L3, L4 emitted from the second light emitting surface T1 will form hexagonal optical patterns P2, P3, P4 on the top surface S2 of the hub 121, and the size of the optical pattern P1 is greater than that of the optical pattern P2, the size of the optical pattern P2 is greater than that of the optical pattern P3, and the size of the optical pattern P3 is greater than that of the optical pattern P4. In this way, when the fan blade 122 rotates in the direction A, the light rays generated by the lamp bead 1311 will pass through the light guide 133, the second mirror 134, and the first mirror 132 to form a time tunnel-like effect on the top surface S2 of the hub 121.

[0138] In this embodiment, a first mirror 132 or a reflective sheet 135 is provided on the side of the second mirror 134 away from the hub 121 to reflect the light rays back to the second mirror 134, but this is not limiting. In other embodiments, only one of the first mirror 132 or the reflective sheet 135 can be provided on the side of the second mirror 134 away from the hub 121 to reflect the light rays back to the second mirror 134, and this also includes only one of the second mirror 134 or the reflective sheet 135.

[0139] In this embodiment, the first mirror 132 and the second mirror 134 are half-reflective mirrors, and the reflective sheet 135 is a full-reflective mirror.

[0140] Please refer to Figure 6 , Figure 6 a perspective view of the second embodiment of the fan of the present application.

Figures 1 to 3 The fan shown in FIG. 2 is substantially the same in structure as the fan shown in FIG. 1, so the same parts will not be described again here, and the different parts will be described as follows. Figures 1 to 3The fan shown can show the time tunnel effect by forming a perspective surface through the perspective slot C1 on the hub 121 when the fan blade assembly 12 rotates. Figure 6 In the fan shown, the material of the hub 121 is transparent, so in this embodiment, the perspective slot C1 does not need to be opened on the hub 121, so the time tunnel effect can be shown when the fan blade assembly 12 rotates or does not rotate, that is Figure 6 The fan shown can show the time tunnel effect as long as it is connected to the power supply.

[0141] In another embodiment of the present application, the material of the hub 121 and the material of the fan blade 122 can also be transparent.

[0142] In another embodiment of the present application, the top surface S2 can also be provided with a logo, which can be a LOGO logo, so that the time tunnel effect and the LOGO logo can be shown when the fan is running or not running, that is, the fan can show the time tunnel effect and the LOGO logo as long as it is connected to the power supply, and the LOGO logo can be one or a combination of graphics, text, and letters.
