Description

Technical Field

[0001] This utility model relates to the field of cooling fan technology, and in particular to a luminous fan. Background Technology

[0002] Current processors generate a lot of heat when running. To ensure that the processor in electronic devices is not damaged by high heat, fans need to be installed on electronic products to dissipate the excessive heat from the processor.

[0003] In addition to their existing cooling functions, fan manufacturers are also focusing on the aesthetics of fans during operation, adding effects such as lighting. Current illuminated fans, based on standard-sized fans, integrate LED strips into the fan frame's inner wall. To maintain the overall fan size, the inner diameter of the frame is reduced, consequently decreasing the fan blade diameter. While this achieves the lighting effect, the smaller blades result in reduced heat dissipation performance.

[0004] There is an urgent need to design a luminous fan that can function without affecting the computer's heat dissipation.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0025] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0026] A type of luminous fan, such as Figures 1 to 4As shown, it includes: a fan blade 1; a fan frame 2, including a housing 21 and two side cover plates 22; the housing 21 has an annular wall 211, the fan blade 1 is placed on the inner wall of the annular wall 211, and the side cover plates 22 form two light-emitting element receiving cavities 215 after being closed with the housing 21; and two light-emitting elements 3, which are respectively disposed in the two light-emitting element 3 receiving cavities 215.

[0027] As an optional implementation, the housing further includes a top shell 212 and a bottom shell 213 arranged in parallel, and two connecting shells 214. The top shell 212 is a square plate with a circular opening in the middle, and the square plate includes two long sides and two short sides. The bottom shell 213 is a square plate with the same length and width as the top shell 212, and has a circular opening at the same position. The circular opening on the top shell 212 is connected to one end of the annular wall 211, and the circular opening on the bottom shell 213 is connected to the other end of the annular wall 211. The space inside the annular wall 211 is used to install the fan blade 1. One long side of the shell 212 is connected to a corresponding long side of the bottom shell 213 via a connecting shell 214. The other long side of the top shell 212 is connected to another corresponding long side of the bottom shell 213 via another connecting shell 214. One short side of the top shell 212 is connected to a corresponding short side of the bottom shell 213 via a side cover plate 22. The other short side of the top shell 212 is connected to another corresponding short side of the bottom shell 213 via another side cover plate 22. Each of the two side cover plates 22 has a light-emitting element 3 receiving cavity 215 between itself and the shell 21.

[0028] Specifically, the housing 21 is a box-like structure with a central opening, and the longer side is slightly longer than the shorter side, forming a top surface, two long side surfaces, and two short side surfaces. The two long side surfaces of the housing 21 are connected by a connecting shell 214, and the two short side surfaces of the housing 21 are respectively connected to the side cover plate 22. The central opening inside the housing 21 is penetrated and closed by the annular wall 211. A motor and a connector 218 are provided on the annular wall 211. The connector 218 is used to fix the fan blade 1 to the annular wall 211. The motor is used to drive the fan blade 1 to rotate.

[0029] As an optional implementation, the light-emitting element 3 receiving cavity 215 is provided with a plurality of light-emitting element 3 seats 216, which are used to place and secure the light-emitting element 3.

[0030] Specifically, the light-emitting element 3 base 216 is distributed on both sides of the light-emitting element 3 receiving cavity 215, and the light-emitting element 3 is fixed by fixing the two ends of the light-emitting element 3.

[0031] As an optional implementation, the plurality of light-emitting element seats 216 are symmetrically distributed along the short side of the housing 21.

[0032] Specifically, there are an even number of light-emitting element 3 seats 216, and there are no less than two light-emitting element 3 seats 216 on each side of the light-emitting element 3 receiving cavity 215, which can enhance the stability of fixing the light-emitting element 3.

[0033] As an optional implementation, each of the side cover plates 22 is provided with a first buckle 221, and the housing 21 is provided with a second buckle 217 corresponding to the first buckle 221. The first buckle 221 and the second buckle 217 cooperate to fix the side cover plate 22 on the housing 21. There are multiple second buckles 217, which are symmetrically arranged on the top shell 212 and the bottom shell 213.

[0034] Specifically, each top shell 212 and bottom shell 213 is provided with a second buckle 217, and each of the two short sides of the top shell 212 and bottom shell 213 is provided with no less than two second buckles 217, that is, each of the light-emitting element 3 receiving cavity 215 is provided with no less than two second buckles 217 at the top and bottom. The number and position of the first buckles 221 on the side cover plate 22 match the number and position of the second buckles 217 in each light-emitting element 3 receiving cavity 215.

[0035] As an optional implementation, the light-emitting element 3 is provided with a plurality of LED beads 31, which are located on the side of the light-emitting element 3 facing away from the fan blade 1.

[0036] Specifically, the side of the light-emitting element 3 facing away from the fan blade 1, that is, the side facing the side cover plate 22, can transmit light through the side cover plate 22 when the light-emitting element 3 emits light.

[0037] As an optional implementation, the housing 21 is provided with a plurality of fasteners, which are used to fix the fan frame 2 to other structures.

[0038] Specifically, the plurality of fasteners are respectively disposed at the four corners of the fan frame 2.

[0039] As an optional implementation, the light-emitting element 3 receiving cavity 215 is the space formed between the annular wall 211 and the short side of the housing 21, and the two light-emitting element 3 receiving cavities 215 are symmetrically arranged at the two short sides of the housing 21.

[0040] Specifically, the long side of the housing 21 is slightly longer than the short side. Therefore, after the circular opening is made, the annular wall 211 is close to the long side of the housing 21, that is, close to the connecting shell 214. However, there is still a space between the annular wall 211 and the short side of the housing 21. This space is the cavity 215 for the light-emitting element 3.

[0041] As an optional implementation, the side cover plate 22 is a light-transmitting plastic part, and when the light-emitting element 3 emits light, it can transmit light through the side cover plate 22.

[0042] Specifically, in a preferred embodiment, the side cover 22 is the same color as the housing 21. When the light-emitting element 3 is not emitting light, the housing 21 and the side cover 22 are integrated; when the light-emitting element 3 emits light, the side cover 22 is translucent.

[0043] As an optional implementation, the housing 21 is integrally formed.

[0044] Specifically, the annular wall 211, the top surface and the bottom surface, the two connecting shells 214, the second buckle 217 and the light-emitting element 3 seat 216 thereon are integrally formed, and the side cover plate 22 is an independent structure.

[0045] By adopting the above technical solution, a fan frame 2 with varying lengths and widths is provided. A light-emitting element 3 receiving cavity 215 is provided on the side of the short side of the fan frame 2, and a light-emitting element 3 seat 216 is provided inside, which can snap the light-emitting element 3 into the fan frame 2. A light-transmitting side cover plate 22 is snapped onto the outer side of the short side of the fan frame 2. When not emitting light, the side cover plate 22 is the same color as the housing 21. When emitting light, the light-emitting element 3 transmits light through the side cover plate 22 to achieve the emitting effect. By placing the light-emitting element 3 between the annular wall 211 and the outer frame of the fan frame 2, compared with the solution of placing the light-emitting element 3 inside the annular wall 211, the aerodynamic structure of the fan blade 1 does not need to be changed, and emitting light can be achieved without affecting the fan's heat dissipation.
