[0028] like Figures 1 to 5 As shown, this is an embodiment of the present invention, relating to a cooling fan with a three-dimensional lighting effect, including a fan body 10, the fan body 10 including a plurality of fan blades 20, a light guide element 30, and an LED circuit board 40; a central hub 50 is connected to the inner center of the fan blades 20; one end of the light guide element 30 extends along the first surface of the fan blade 20 to form a light-emitting point 31, and / or one end of the light guide element 30 extends from the cavity 51 of the central hub 50 along the first surface of the fan blade 20, passes through the fan blade 20, and forms a light-emitting point 31 on the second surface of the fan blade 20; the first surface of the fan blade 20 is an arc-shaped curved surface, the light guide element 30 extends along the curvature of the arc-shaped curved surface, a light-receiving point 32 is provided at the end of the light guide element 30 facing the central hub 50, and a light-shielding sleeve (not shown in the figure) is provided at the extension of the light guide element 30 along the first surface of the fan blade 20; the LED circuit board 40 is connected to a plurality of LED beads 41, the LED beads 41 being disposed inside the cavity 51.

[0029] Furthermore, light guide elements 30 of varying lengths extend from one end of the cavity 51 of the central hub 50 along the first surface of the fan blade 20, and can pass through the fan blade 20 to form a light-emitting point 31 on the second surface and / or directly form a light-emitting point 31 on the first surface. This diverse light guiding method can create rich light-emitting effects to meet different decorative and visual needs. The light guide element 30 extends along the curvature of the arc surface of the first surface of the fan blade 20, so that the light guide element 30 fits better with the fan blade 20. On the one hand, it ensures the integrity and aesthetics of the structure, and on the other hand, it reduces the light refraction loss caused by non-fitting, thereby improving the light guiding efficiency. A light shield (not shown in the figure) is set at the extension of the light guide element 30 along the first surface of the fan blade 20, which can effectively prevent light from leaking from the side, so that the light is more concentrated and propagates along the light guide element 30, enhancing the brightness and clarity of the light-emitting point 31 and improving the overall visual effect.

[0030] In some embodiments, the fan body 10 further includes a voice control module 11 and a wireless communication module 12. During operation, the user issues a voice command (such as "turn the light red" or "turn on the light breathing mode"). The voice control module 11 collects and recognizes the command and sends it to the LED circuit board 40 via the wireless communication module 12. After the control chip of the LED circuit board 40 parses the command, it drives the LED beads 41 to operate according to the set parameters. The light is conducted through the light guide element 30, presenting a corresponding visual effect when the fan blades 20 rotate. For example, if the user's voice triggers "switch light mode," the LED beads 41 can cycle through red, green, blue, and other colors, forming dynamic light and shadow through the light guide element 30, realizing the function of voice-interactive control of light changes, improving the user experience and the product's intelligence level.

[0031] Furthermore, the plurality of fan blades 20 are evenly distributed circumferentially around the central hub 50. Specifically, the even circumferential distribution of the fan blades 20 around the central hub 50 enhances the structural stability of the fan body 10, ensures the dynamic balance of the fan blades 20 during rotation, reduces vibration and noise caused by the shift of the center of gravity, and improves the smoothness of operation.

[0032] Furthermore, the top of the fan blade 20 is provided with a forward-extending protrusion 21, which has a streamlined curved surface structure; one side of the protrusion 21 is provided with a plurality of serrated structures 22, which are connected and distributed along the circumference of the fan blade 20. Specifically, the streamlined protrusion 21 optimizes the airflow direction, reduces eddy current generation, and improves the heat dissipation efficiency; the serrated structures 22 cut the airflow and disrupt the airflow vibration frequency, achieving efficient noise reduction and enhancing heat dissipation performance in a dual manner.

[0033] Furthermore, a mounting groove 23 is provided on one side edge of the fan blade 20. The mounting groove 23 is opened along the extending direction of the fan blade 20. The mounting groove 23 is used to securely mount the light guide element 30 and realize the light path conduction. Specifically, the mounting groove 23 secures the light guide element 30 to prevent it from falling off, while optimizing the light path conduction path to ensure that the light from the LED beads 41 is uniformly introduced into the light guide element 30, thereby improving the consistency of the luminous effect. In some embodiments, the light guide element 30 can be directly bonded to the fan blade 20 with adhesive.

[0034] Furthermore, a plurality of the LED beads 41 are arranged in a ring array, and the LED beads 41 are adjusted by an external control circuit board (not shown in the figure). The LED beads 41 are connected to the light-receiving point 32. Specifically, the ring array distribution of the LED beads 41 improves the uniformity of light guiding, meets the needs of diverse scenarios, and enhances the personalization and technological feel of the product; the external control circuit board (not shown in the figure) effectively adjusts the parameters such as the emission color, brightness, and flicker frequency of the LED beads 41, improving the visual experience; the LED beads 41 uniformly provide light source to the light guide element 30, ensuring uniform brightness of each part of the light guide element 30, avoiding large differences in brightness, and improving the overall light emission quality.

[0035] Furthermore, the fan body 10 also includes a drive module 13, which drives the fan blades 20 to rotate. The output shaft of the drive module 13 is connected to the cavity 51, which is used for power transmission between the fan blades 20 and the drive module 13. Specifically, the cavity 51 is connected to the output shaft of the drive module 13 to ensure stable power transmission and guarantee the reliability of the fan blades 20 rotation. In some embodiments, the drive module 13 can be a brushless motor or other drive device.

[0036] Furthermore, the fan body 10 also includes a fixed bracket 60, which includes a circular base plate 61, an assembly column 62, and several mounting arms 63. The center of the circular base plate 61 is connected to the assembly column 62. The assembly column 62 is adapted to the drive module 13 and is axially positioned by interference fit or key connection. The several mounting arms 63 are respectively connected to the outer edge of the circular base plate 61. The number of mounting arms 63 is at least three, and the three mounting arms 63 are arranged in a circumferential array. The end of each mounting arm 63 is provided with a mounting through hole 64 for fastening with screws. Specifically, the combination of the circular base plate 61, the assembly column 62, and the mounting arms 63 not only achieves axial positioning of the drive module 13, but also allows for screw fastening through the through holes at the ends of the mounting arms 63, making installation convenient and secure. The circumferentially arrayed arms disperse the stress points, enhancing the overall structural balance. The mounting through holes 64, combined with screw fastening, improve the fan's installation stability and prevent vibration-induced loosening.

[0037] Furthermore, a snap-fit ​​structure 65 is provided on one side of the circular substrate 61. The snap-fit ​​structure 65 is used to cooperate with an external control circuit board (not shown in the figure) to achieve limited installation. Specifically, the snap-fit ​​structure 65 cooperates with the external control circuit board (not shown in the figure) to achieve quick limited installation, simplify the assembly process, and at the same time, the compact layout saves space and improves product integration.

[0038] Furthermore, the fan body 10 also includes noise-reducing ribs 14. Multiple noise-reducing ribs 14 are provided, and they are distributed in an array on the surface of the fan blade 20 in a raised form, with some ribs extending along the length of the fan blade 20. Specifically, the array-distributed noise-reducing ribs 14 disrupt airflow turbulence in a raised form, reducing airflow friction noise, and the design of extending along the length of the fan blade 20 expands the noise reduction range and improves the fan's quietness performance.

[0039] This invention provides a dynamic luminous visual effect to the fan through the light guide element 30, LED beads 41, and light path conduction design; the central hub 50, fixed bracket 60, and other structures ensure the fan's operational stability and ease of installation. The overall design integrates optimized heat dissipation, noise control, decorative lighting, and stable installation, enhancing the product's overall competitiveness and making it suitable for electronic equipment scenarios that require heat dissipation, quiet operation, and aesthetics.
