Wherein the blades have a reflective surface. When the fan blade is installed on the fan frame, the light source on the outside shines on the reflective surface, and the reflective surface on the blade reflects the light source, so that each blade of the fan blade can be visually seen as having a light source projection effect like a lamp, and the visual effect of the fan blade rotation is also increased.

Description

Technical Field

[0001] This utility model relates to a fan, and more particularly to a fan blade with a reflective surface added to it, so that when illuminated by a light source, it forms a heat dissipation fan blade with the effect of reflecting the light source. Background Technology

[0002] In recent years, in addition to improvements in basic functions such as quiet operation, power consumption and fault detection, the small fans used inside various electronic devices have also evolved into small fans with diverse shapes and lighting effects.

[0003] Current small fans, for example, have a row of light-emitting diodes mounted on the fan blade hub. Controlled by an IC circuit, they can display cool visual effects such as 3D images, numbers, or text as the fan blades rotate. This is known as the persistence of vision, which refers to the phenomenon where, when the human eye observes an object, the light signal is transmitted to the brain. After a short period of time, the visual image does not immediately disappear; the human eye can retain the image for about 0.1 seconds. This residual vision is called persistence of vision.

[0004] Alternatively, the fan blades and frame can be made of transparent light-guiding plastic material, and several light-emitting diodes can be installed on the fan's circuit board or frame. When the circuit board drives the fan blades to rotate, these light-emitting diodes are lit at the same time, so that the light source generated by these light-emitting diodes is projected onto the fan frame or fan blades, so that the fan frame and fan blades produce a light-emitting effect when they rotate.

[0005] Although the aforementioned fan structure has a light source display effect, the overall structure and circuit design are relatively complex and the manufacturing cost is high, which in turn increases the price of the fan.

[0006] Therefore, the challenge this creation aims to address is how to make the fan blades produce a light source effect while rotating, and at the same time make the fan easier to manufacture and reduce production costs. Utility Model Content

[0007] Therefore, the main purpose of this creation is to address the shortcomings of tradition. This creation redesigns the fan blades by adding a reflective surface to each blade. When the fan blades are installed on the fan frame, external light sources shine on the reflective surface, and the reflective surface on the blades reflects the light source. Visually, each blade of the fan blade can be seen to produce a light source projection effect as if it has a lamp, which also enhances the visual experience of the fan blades rotating.

[0008] Furthermore, this invention provides a heat dissipation fan blade with a reflective surface, comprising: a fan blade. The fan blade has a hub and a plurality of blades extending radially outward from the hub. The blades have a reflective surface.

[0009] Furthermore, each of these blades has a windward side, a leeward side, a convex flange, a concave flange, and a side edge.

[0010] Furthermore, the reflective surface is disposed on the windward side, the leeward side, the flange portion, or the concave flange portion.

[0011] Furthermore, the reflective surface is composed of a plurality of recesses, each of which has a spacing between it.

[0012] Furthermore, the reflective surface is composed of a plurality of recesses, each of which is arranged in a continuous, uninterrupted manner.

[0013] Furthermore, the reflective surface is composed of a plurality of protrusions, each of which has a spacing between it.

[0014] Furthermore, the reflective surface is composed of a plurality of protrusions, each of which is arranged in a continuous, uninterrupted manner.

[0015] Furthermore, an outer ring wall is fixed to the side edge of these blades.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the related listed items.

[0047] The technical details and specific descriptions of this work are explained below with accompanying illustrations:

[0048] Please see Figure 1 , 2 This is a three-dimensional schematic diagram of the fan blades in this creation. Figure 1 A top view schematic diagram. As shown in the figure: The heat dissipation fan blade with a reflective surface of this invention includes a hub 101 and a plurality of blades 102 extending radially outward from the hub 101. A shaft (not shown) and a magnetic element (not shown) are disposed inside the hub 101. Furthermore, an outer ring wall 103 is fixed to the side edge 1025 of the blades 102, and a reflective surface 104 is provided on the surface of the blades 102.

[0049] It is worth mentioning that the reflective surface 104 can be disposed on the windward side 1021 and the leeward side 1022 of the blade 102 (e.g., Figure 3 As shown), on the flange 1023 or the concave flange 1024. The fan blade 10 is mounted on the fan frame 20 (as shown). Figure 4 As shown, when an external light source shines on the reflective surface 104, the reflective surface 104 will reflect or refract the light source, so that each blade 102 of the fan blade 10 can be seen to produce a light source projection effect like a lamp, and at the same time, it will increase the visual feeling of the fan blade 10 rotating.

[0050] Please see Figures 3-4 , tied to Figure 2 Enlarged partial sectional view of position 3-3 and system Figure 3 Another embodiment diagram; see also Figure 1 , 2 As shown in the figure: During the manufacturing of the fan blade 10, a pattern design of a reflective surface 104 is added to the mold cavity of the mold (not shown in the figure) for manufacturing the fan blade 10. After the fan blade 10 is injection molded, a reflective surface 104 is formed on each blade 102 of the fan blade 10. The reflective surface 104 is composed of a plurality of recesses 1041, and each recess 1041 is spaced apart by a distance 1042 (e.g., ...). Figure 3 As shown). The fan blade 10 is mounted on the fan frame 20 (as shown). Figure 4 As shown, when an external light source shines into the recesses 1041, the recesses 1041 reflect the light source, making each blade 102 of the fan blade 10 appear to have a light source projection effect like a lamp, while also increasing the visual perception of the fan blade 10 rotating.

[0051] In addition to the arrangement of the aforementioned recesses 1041 with a spacing 1042 between them, the recesses 1041 can also be arranged in a continuous manner without spacing (e.g. Figure 4 As shown). Similarly, the fan blade 10 is mounted on the fan frame 20 (as shown). Figure 4 As shown, when an external light source shines into the recesses 1041, the recesses 1041 reflect the light source, making each blade 102 of the fan blade 10 appear to have a light source projection effect like a lamp, while also increasing the visual perception of the fan blade 10 rotating.

[0052] Please see Figure 5 ,Tie Figure 3 A schematic diagram of another embodiment; also refer to Figures 1-4 As shown in the figure: It is worth mentioning that the concave holes 1041 of the reflective surface 104 (104a) of this invention can also be protrusions 1041a. Each protrusion 1041a is arranged with a spacing 1042a or without spacing on the blade 102. When the fan blade 10 is installed on the fan frame 20 (e.g. Figure 4 As shown, when an external light source shines on these protrusions, the protrusions reflect the light source, making each blade 102 of the fan blade 10 appear to have a light source projection effect like a lamp, while also increasing the visual perception of the fan blade 10 rotating.

[0053] Please see Figure 6 , 7 This is a three-dimensional exploded view of the fan blades and frame of this creation, and a related diagram. Figure 6 A three-dimensional schematic diagram of the combined appearance; please refer to the following: Figures 1-4 As shown in the figure: When the fan blade 10 and the fan frame 20 are assembled, the fan frame 20 has a support 201 and a peripheral wall portion 202 surrounding the support 201. A central shaft 203 is formed by protruding upward from the inner center of the support 201. The central shaft 203 has a shaft hole 2031, and at least one bearing (not shown in the figure) is disposed in the shaft hole 2031. An assembly space 204 is left between the outer periphery of the central shaft 203 and the peripheral wall portion 202. The assembly space 204 is used to assemble the coil assembly (not shown in the figure), the circuit board (not shown in the figure), and the fan blade 10.

[0054] After the fan blade 10 is assembled in the assembly space 204, when the circuit board transmits power to the coil group, the coil group generates magnetic force, which can drive the magnetic element (not shown in the figure) arranged inside the hub 101, causing the fan blade 10 to rotate.

[0055] When the fan blades 10 are mounted on the fan frame 20, and an external light source shines into the recesses 1041 of the reflective surface 104, the recesses 1041 will reflect the light source, so that each blade 102 of the fan blades 10 can be seen to produce a light source projection effect like a lamp, and at the same time, it will increase the visual perception of the fan blades 10 rotating.
