Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a fan that can form an aperture effect. Background Technology

[0002] A cooling fan is a common cooling device used in electronic and mechanical systems to help dissipate the heat generated by the operation of components, thereby maintaining the device's normal operating temperature. When equipment (such as computers, servers, or car engines) is running, its internal electronic components generate heat. If this heat cannot be effectively dissipated, it may cause the equipment to overheat, thus affecting its performance.

[0003] The prior art can be referenced in Chinese Patent No. CN 222823413 U, which discloses an adjustable cooling fan, including an outer fan frame, an inner fan frame, a drive unit, and fan blades. The inner side of the outer fan frame has several adjustable plates spaced apart, and the outer side of the inner fan frame has several positioning protrusions, each of which engages with one of the adjustable plates. A mounting bracket is provided in the inner fan frame, and the drive unit is fixedly mounted on the mounting bracket. The fan blades are fixedly mounted on the rotating end of the drive unit. This fan, by engaging the adjustable plates with the positioning protrusions, allows for adjustment of the fan blade tilt angle for better heat dissipation, but it lacks a light-emitting function.

[0004] The inventor is aware that existing fans with light-emitting functions make the entire fan blade transparent, allowing light from a fixed light source on the other side to pass through. This structure only allows the entire fan blade to emit light, and the light and shadow effects are rigid, unable to form a halo, and thus cannot meet people's aesthetic needs. Utility Model Content

[0005] This invention provides a fan that can form an aperture effect. When the fan rotates, an aperture can be formed on the front of the fan blades, making it more aesthetically pleasing.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fan capable of creating an aperture effect, comprising:

[0008] Frame;

[0009] A fan blade, rotatable relative to the frame, includes a hub and multiple blades, each blade fixedly connected to the hub. Each blade has a first mounting groove, one end of which opens to form a first opening on the front of the blade. The hub has a second mounting groove, one end of which communicates with the other end of the first mounting groove, and the other end of which has a second opening.

[0010] The light-emitting component includes an optical fiber strip, an LED bead, and a circuit board. The optical fiber strip is disposed in a first mounting slot and a second mounting slot. A first end of the optical fiber strip extends out from the first opening, and a second end of the optical fiber strip extends out from the second opening and faces the LED bead. The LED bead is disposed on the circuit board.

[0011] Preferably, there are multiple optical fiber strips, and the distance between the first end of the multiple optical fiber strips and the center of the hub is different.

[0012] Preferably, the plurality of optical fiber strips are located on different blades.

[0013] Preferably, there are three optical fiber strips and seven blades.

[0014] Preferably, the first and second ends of the optical fiber strip are both straight strips, and the shape of the optical fiber strip is Z-shaped.

[0015] Preferably, the fan further includes a heat shrink tubing, which is sleeved on the outside of the optical fiber strip, with one heat shrink tubing corresponding to one optical fiber strip.

[0016] Preferably, the heat shrink tubing is fixed in the first mounting groove and the second mounting groove by adhesive.

[0017] Preferably, there are multiple LED beads, and the multiple LED beads are arranged in a ring array on the side of the circuit board facing the optical fiber strip.

[0018] Preferably, the fan further includes a motor, which is mounted on the frame and is centrally connected to the hub to drive the fan blades to rotate relative to the frame. The back of the hub is provided with a groove to accommodate the motor, and the circuit board is connected to the motor to drive the motor to operate.

[0019] Preferably, the circuit board is sleeved and soldered onto the stator of the motor.

[0020] The above technical solution has the following beneficial effects: the circuit board controls the lamp beads to turn on, the lamp beads emit light, and the optical fiber strip plays the role of guiding light. The second end faces the lamp beads, receives the light from the lamp beads, and guides the light from the lamp beads out from the first end. This structure is ingenious and practical, and the cost is low. By guiding the light from the lamp beads out from the first end, the user can see the fan blades emitting light from the front, and a halo effect can be formed when the fan blades are operating.

[0031] To explain in detail the technical content, structural features, objectives, and effects of the technical solution, the following description is provided in conjunction with specific embodiments and accompanying drawings.

[0032] Please see Figures 1 to 8 This embodiment describes a fan capable of creating an aperture effect, the fan comprising:

[0033] Frame 1;

[0034] Fan blade 2, rotatable relative to frame 1, includes a hub 5 and multiple blades 4, each blade 4 fixedly connected to the hub 5. Each blade 4 has a first mounting groove 10, one end of which opens to form a first opening 3 on the front surface of the blade 4. The hub 5 has a second mounting groove 11, one end of which communicates with the other end of the first mounting groove 10, and the other end of the second mounting groove 11 has a second opening 7.

[0035] The light-emitting component includes an optical fiber strip 9, an LED bead 8, and a circuit board 6. The optical fiber strip 9 is disposed in the first mounting groove 10 and the second mounting groove 11. The first end 13 of the optical fiber strip 9 extends out from the first opening 3, and the second end 14 of the optical fiber strip 9 extends out from the second opening 7 and faces the LED bead 8. The LED bead 8 is disposed on the circuit board 6.

[0036] Multiple blades 4 are radially fixed on the hub 5. The first mounting groove 10 and the second mounting groove 11 are connected. The optical fiber strip 9 is placed in the first mounting groove 10 and the second mounting groove 11. The first opening 3 of the first mounting groove 10 is located on the front of the blade 4. At this time, the front is the side with the aperture. The first end 13 of the optical fiber strip 9 extends out from the first opening 3. The second opening 7 of the second mounting groove 11 is set opposite to the lamp bead 8. The second end 14 of the optical fiber strip 9 extends out from the second opening 7.

[0037] Circuit board 6 controls the LED bead 8 to turn on, and the LED bead 8 emits light as a light source. The optical fiber strip 9 acts as a light guide, with its second end 14 facing the LED bead 8 to receive the light from the LED bead 8 and guide the light from the LED bead 8 out through the first end 13. This structure is ingenious and practical, and inexpensive to manufacture. By guiding the light from the LED bead 8 out through the first end 13, the user can see the fan blade 2 emitting light from the front, and when the fan blade 2 is operating, it can form a halo effect.

[0038] Please see Figure 4 In this embodiment, there are multiple optical fiber strips 9, and the distance between the first end 13 of each optical fiber strip 9 and the center of the hub 5 is different. This design allows the fan blades 2 to form multiple apertures when rotating, enhancing the visual depth. Figure 4 The diagram shows three fiber optic strips 9. The first end 13 of the first fiber optic strip 96 is furthest from the center of the hub 5. The first end 13 of the third fiber optic strip 98 is closest to the center of the hub 5. The distance from the first end 13 of the second fiber optic strip 97 to the center of the hub 5 is shorter than the distance from the first end 13 of the first fiber optic strip 96 to the center of the hub 5, but longer than the distance from the first end 13 of the third fiber optic strip 98 to the center of the hub 5. When the fan blade 2 rotates, it forms three concentric light rings.

[0039] Please see Figures 3 to 4In this embodiment, multiple optical fiber strips 9 are located on different blades 4. This design results in better aperture performance and a more uniform weight distribution of the fan blades 2. Figures 3 to 4 The diagram illustrates three fiber optic strips 9 and seven blades 4. The first fiber optic strip 96 is located on the first blade 120, the second fiber optic strip 97 is located on the second blade 121, and the third fiber optic strip 98 is located on the third blade 122. The other four blades do not have fiber optic strips. In other embodiments, multiple fiber optic strips 9 may be located on a single blade 4, but this increases the weight of the blade 4, potentially affecting the stability of the fan operation and causing excessively high local brightness, forming a glaring halo. Therefore, it is preferable that the multiple fiber optic strips 9 are located on different blades 4.

[0040] Please see Figure 4 In this embodiment, the shape of the optical fiber strip 9 is approximately Z-shaped. Both the first end 13 and the second end 14 of the optical fiber strip 9 are straight strips, and the portion between the first end 13 and the second end 14 is shaped like an arc-shaped adapter leaf. This helps the second end 14 better receive the light emitted by the LED bead 8, allowing the first end 13 to direct the light in a more concentrated manner, forming a clear light spot.

[0041] Please see Figure 4 and Figure 8 In this embodiment, the fan further includes a heat-shrink tubing 12, which is fitted over the outside of the optical fiber strip 9, with one heat-shrink tubing 12 corresponding to one optical fiber strip 9. This design makes the light guiding effect of the optical fiber strip 9 more stable. The heat-shrink tubing 12 enhances the fixing strength of the optical fiber strip 9, reduces the risk of breakage due to high-speed rotation, and extends the service life of the optical fiber strip 9. In some embodiments, some optical fiber strips 9 are fitted with heat-shrink tubing, while others are not.

[0042] Please see Figure 3 and Figure 8 In this embodiment, the heat shrink tubing 12 is fixed in the first mounting groove 10 and the second mounting groove 11 by adhesive. Adhesive is readily available and easy to use, provides good fixation, reduces wear on the heat shrink tubing 12, and prevents the heat shrink tubing 12 and the optical fiber strip 9 from falling off during high-speed rotation.

[0043] Please see Figure 2 and Figure 5 In this embodiment, there are multiple LED beads 8, which are arranged in a ring array on the side of the circuit board 6 facing the optical fiber strip 9. This design ensures that the second end 14 of the optical fiber strip 9 receives more light, resulting in a better aperture effect when the fan blade 2 rotates. Figure 5The diagram illustrates eight LEDs 8 arranged in a circular array on the side of the circuit board 6 facing the optical fiber strip 9. These eight LEDs 8 act as light sources facing the optical fiber strip 9. When the optical fiber strip 9 rotates with the fan blade 2, its second end 14 fully receives the light from the LEDs 8. In other embodiments, only one LED 8 is used, but this results in weaker light received by the second end 14 of the optical fiber strip 9, and the aperture effect formed when the fan blade 2 rotates is less pronounced. Therefore, having multiple LEDs 8 is the preferred solution.

[0044] Please see Figure 1 and Figure 2 In this embodiment, the fan further includes a motor 16, which is mounted on the frame 1 and centrally connected to the hub 5. The motor 16 drives the fan blades 2 to rotate relative to the frame. A groove 15 is provided on the back of the hub 5 to accommodate the motor 16. The circuit board 6 is connected to the motor 16 to drive its operation. The central connection between the motor 16 and the hub 5 allows for effective heat dissipation during operation. Figure 2 The illustration shows that one end of the motor 16 is housed in the groove 15, while the other end protrudes from the groove 15. The protruding end of the groove 15 is connected to the frame 1, making the fan structure compact and effectively reducing the fan's size. In other embodiments, the motor 16 is entirely housed in the groove 15, and one end of the frame 1 has a protrusion that connects to the motor 16.

[0045] Please see Figure 2 and Figure 7 In this embodiment, the circuit board 6 is sleeved and soldered onto the stator 116 of the motor 16. The circuit board 6 is circular in shape, with a circular snap-fit ​​112 at its center. The motor 16 has a circular cylindrical wall 113. The circuit board 6 is snapped onto the cylindrical wall 113 via the circular snap-fit ​​112 and soldered to the stator 116. In other embodiments, the circuit board 6 is threadedly connected to the motor 16. Specifically, the circuit board 6 and the motor 16 have mating threaded holes, and the circuit board 6 and the motor 16 are connected by screwing bolts into the threaded holes.

[0046] In this embodiment, the circuit board 16 is a PCBA (Printed Circuit Board Assembly), which is electrically connected to the motor 16 and the LED beads 8, thereby driving the motor 16 and the LED beads 8 to turn on or off.
