[0035] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0036] The existing luminous fan structure is relatively complex and the assembly process requires high precision, resulting in low assembly efficiency and the inability to balance the luminous effect and cost.

[0037] Please refer to Figures 1 to 9 A light-emitting fan includes: a fixed base 3, a drive assembly (not shown), an impeller assembly 1, a light guide assembly 2, and a light-emitting assembly (not shown). The drive assembly is mounted on the fixed base 3; the impeller assembly 1 is connected to the output end of the drive assembly; the light guide assembly 2 is embedded in the impeller assembly 1; and the light-emitting assembly is mounted on the fixed base 3 and corresponds to the light guide assembly 2.

[0038] The central portion of the impeller assembly 1 is provided with an arcuate light guide groove 114 extending through the thickness of the impeller assembly 1. At least two arcuate light guide grooves 114 are provided, with spacer ribs 113 disposed between the arcuate light guide grooves 114. Specifically, the arcuate light guide grooves 114 enclose an annular through-groove, and the spacer ribs 113 are disposed within the arcuate light guide groove 114 to connect the structures on both sides of the arcuate light guide groove 114.

[0039] The light guide assembly 2 includes a light guide member 21 and a light shielding member 22. The light guide member 21 includes a central portion 211 and an extension portion 212. The extension portion 212 extends from the edge of the central portion 211 in a direction perpendicular to the plane in which the central portion 211 is located. The extension portion 212 has a mounting notch 215, which is arranged corresponding to the spacer rib 113. The light shielding member 22 is arranged on the side of the central portion 211 away from the extension portion 212, and the extension portion 212 enters the impeller assembly 1 through the arc-shaped light guide groove 114. Specifically, the light guide member 21 is an overall cylindrical structure, with the central portion 211 as the bottom of the cylinder and the extension portion 212 as the wall of the cylinder. The extension portion 212 is provided with a mounting notch 215. During assembly, the light shielding member 22 is arranged on the outside of the central portion 211, that is, on the side of the central portion 211 away from the extension portion 212. The extension portion 212 extends into the impeller assembly 1 through the arc-shaped light guide groove 114, so that the central portion 211 abuts the impeller assembly 1. That is, after the installation notch 215 of the light guide 21 clears the spacing ribs 113, the light guide 21 is inserted into the impeller assembly 1 through the arc-shaped light guide groove 114, allowing the light guide 21 to rotate together with the impeller assembly 1. The plug-in assembly ensures a precise fit between the light guide 21 and the impeller assembly 1, while reducing assembly difficulty. It can effectively ensure that the light guide 21 is not easily dislodged or shaken during high-speed rotation, thereby ensuring the balance of the impeller assembly 1 during operation, thereby achieving better wind pressure and air volume, and reducing wind noise.

[0040] Specifically, the drive assembly is a rotary motor, and the light-emitting assembly can be an ARGB light assembly mounted around the drive assembly on the fixed base 3. Light emitted by the light-emitting assembly is transmitted from the extension 212 to the central portion 211, while being shielded by the light shielding member 22 to form an annular lighting area. The light guide 21 rotates with the impeller assembly 1. At high speeds, the light shielding caused by the spacer ribs 113 is negligible. By controlling the color, position, and frequency of the light emitted by the light-emitting assembly, the annular lighting area can be formed to display a variety of lighting effects.

[0041] As can be understood, the luminous fan provided by the present invention incorporates the light guide assembly 2 into the impeller assembly 1, with the extension 212 of the light guide 21 fitting into the arcuate light guide groove 114. This simplifies assembly while effectively preventing the light guide assembly 2 from falling off or shaking during high-speed rotation. It also ensures the balance of the impeller assembly 1, thereby achieving better air pressure and volume and reducing wind noise. While maintaining the luminous fan's heat dissipation performance and lighting effects, the assembly difficulty is significantly reduced, improving assembly efficiency.

[0042] Specifically, the driving component and the light-emitting component are electrically connected to the computer device, and the user can adjust the speed and light of the light-emitting fan through the computer device.

[0043] Preferably, the shading member 22 is made of metal material, thereby improving the appearance and texture of the light-emitting fan. Specifically, the shading member 22 can be made of aluminum plate, which effectively improves the appearance and texture while being light in weight, thereby ensuring the heat dissipation effect.

[0044] In some embodiments, the impeller assembly 1 includes a hub 11 and blades 12. The hub 11 includes an outer cylinder 111 and an inner cylinder 112. Spacer ribs 113 are disposed between the inner cylinder 112 and the outer cylinder 111. The outer wall of the inner cylinder 112, the inner wall of the outer cylinder 111, and the spacer ribs 113 together form an arcuate light guide groove 114. The blades 12 surround and connect to the outer cylinder 111. Specifically, the blades 12 are connected to the outer wall of the outer cylinder 111, and the spacer ribs 113 are disposed between the inner wall of the outer cylinder 111 and the outer wall of the inner cylinder 112. This forms an arcuate light guide groove 114 between the outer cylinder 111 and the inner cylinder 112, allowing light from the light-emitting assembly to be transmitted only along the arcuate light guide groove 114, preventing light crosstalk and improving the visual experience.

[0045] Specifically, the impeller assembly 1 is integrally formed and made of opaque PVC resin, thereby ensuring the overall structural strength and light guiding effect.

[0046] In some embodiments, the outer diameter of the inner cylinder 112 is larger than the inner diameter of the extension portion 212, and the inner diameter of the outer cylinder 111 is larger than the outer diameter of the extension portion 212. That is, the inner diameter of the extension portion 212 of the light guide 21 is slightly smaller than the outer diameter of the inner cylinder 112, and the outer diameter of the extension portion 212 is slightly smaller than the inner diameter of the outer cylinder 111. In this way, during assembly, the extension portion 212 slightly expands due to the elasticity of the material of the extension portion 212, so that the light guide 21 can be tightly fitted with the hub portion 11 after assembly, ensuring the assembly effect.

[0047] Preferably, the end of the extension portion 212 has an arc chamfer, which makes it easier for the operator to insert the extension portion 212 into the arc-shaped light guide groove 114, thereby reducing assembly difficulty and improving assembly efficiency.

[0048] Preferably, the thickness of the extension portion 212 is less than or equal to the width of the arc-shaped light guiding groove 114 .

[0049] Preferably, the material of the light guide member 21 is ABS plastic, which ensures the light guiding effect while taking into account both structural strength and light guiding performance.

[0050] In some embodiments, the rotation axes of the light guide 21, the light shielding member 22 and the impeller assembly 1 are aligned in a straight line. This arrangement ensures the balance of the light-emitting fan after assembly, thereby achieving better wind pressure and volume and reducing wind noise.

[0051] In some embodiments, the light guide assembly 2 further includes a fitting 23, which is annular in structure and disposed at the end of the extension 212 away from the central portion 211. The fitting 23 is disposed between the extension 212 and the sidewall of the hub portion 11. Specifically, the fitting 23 is annular in structure and is embedded at the end of the extension 212. This strengthens the fit between the light guide 21 and the hub portion 11, ensuring a tighter assembly and preventing the light guide 21 from falling out.

[0052] In some embodiments, the interlocking member 23 includes an interlocking wall, a blocking strip, and an inner ring. The inner ring is connected to the interlocking wall via the blocking strip, which is positioned corresponding to the mounting notch 215. The interlocking wall is positioned between the extension 212 and the inner wall of the outer cylinder 111. After the interlocking wall is positioned, the blocking strip fits into the mounting notch 215, further strengthening the fit between the light guide 21 and the hub 11 and ensuring a tighter assembly. The blocking strip and inner ring also facilitate installation and positioning of the interlocking member 23, reducing assembly difficulty. Specifically, the end of the extension 212 distal from the center portion 211 is located between the interlocking wall and the inner ring.

[0053] Specifically, the engaging member 23 is made of a transparent material to ensure a light guiding effect.

[0054] Preferably, the engaging wall may adopt a wedge-shaped structure so that the engaging wall can be more smoothly embedded between the extension portion 212 and the inner wall of the outer cylinder 111 , thereby reducing the difficulty of assembly and improving the assembly effect.

[0055] In some embodiments, the inner ring is sleeved on the inner cylinder 112. This arrangement limits the position of the engaging member 23 and prevents the engaging member 23 from interfering with other structures of the light-emitting fan, thereby ensuring the stability of the overall operation.

[0056] In some embodiments, four spacer ribs 113 are provided, symmetrically distributed in the middle of the impeller assembly 1. That is, the spacer ribs 113 are distributed in a cross shape, ensuring the overall balance of the light-emitting fan during high-speed rotation. At the same time, the light guide 21 is evenly stressed during rotation, thereby increasing the service life of the light-emitting fan.

[0057] In some embodiments, a through hole 213 is provided in the central portion 211. That is, the central portion 211 is a hollow structure, and the light shielding member 22 covers the through hole 213 after being provided, effectively reducing costs and preventing light interference.

[0058] In some embodiments, an engaging step 214 is provided around the through hole 213, and the light shielding member 22 is disposed within the engaging step 214. This allows the outer surface of the outer cylinder 111 to be flush with the outer surfaces of the light guide 21 and the light shielding member 22, ensuring the consistency of the appearance of the light-emitting fan and improving the appearance quality.

[0059] Specifically, the height of the inner cylinder 112 is lower than that of the outer cylinder 111 , so that the outer surface of the outer cylinder 111 can be flush with the outer surfaces of the light guide 21 and the light shielding member 22 after the light guide 21 is assembled.

[0060] like Figures 1 to 9 As shown, the first embodiment of the present invention is: a luminous fan, comprising:

[0067] The light guide assembly 2 includes a light guide member 21 and a light shading member 22. The light guide member 21 includes a central portion 211 and an extension portion 212. The extension portion 212 extends from the edge of the central portion 211 in a direction perpendicular to the plane where the central portion 211 is located. The extension portion 212 has a mounting notch 215, and the mounting notch 215 is arranged corresponding to the spacer rib 113; the light shading member 22 is arranged on a side of the central portion 211 away from the extension portion 212; the extension portion 212 enters the impeller assembly 1 through the arc-shaped light guide groove 114.

[0068] The driving component is a rotating motor, and the light-emitting component is an ARGB lamp group arranged around the driving component on a fixed base 3.

[0069] The impeller assembly 1 includes a hub portion 11 and blades 12. The hub portion 11 includes an outer tube 111 and an inner tube 112. Spacer ribs 113 are provided between the inner tube 112 and the outer tube 111. The outer wall of the inner tube 112, the inner wall of the outer tube 111 and the spacer ribs 113 together form an arc-shaped light guide groove 114; the blades 12 are arranged around the outer tube 111 and connected to the outer tube 111.

[0071] The rotation axes of the light guide member 21 , the light shielding member 22 and the impeller assembly 1 are aligned on the same straight line.

[0072] In this embodiment, four spacer ribs 113 are provided. The spacer ribs 113 are symmetrically distributed in the middle of the impeller assembly 1 , and four mounting notches 215 of the light guide member 21 are correspondingly provided.

[0073] In this embodiment, a through hole 213 is provided in the center portion 211, and an engaging step 214 is provided around the through hole 213. The light shielding member 22 is disposed in the engaging step 214.

[0074] In this embodiment, the light shielding member 22 is an aluminum plate, the light guide member 21 is made of ABS plastic, and the impeller assembly 1 is integrally formed and made of opaque PVC resin.

[0075] The operating principle of the present invention is as follows: During assembly, the operator aligns the mounting notch 215 of the extension 212 of the light guide 21 with the spacer rib 113, inserts the light guide 21 into the hub 11 along the arcuate light guide groove 114, and waits until the center portion 211 abuts the hub 11. At this point, the outer surface of the outer cylinder 111 is flush with the outer surface of the light guide 21.
