Description

Technical Field

[0001] This utility model relates to cooling fans, and in particular to a cooling fan with an easily replaceable light guide component. Background Technology

[0002] Regarding cooling fans, there are already cooling fans on the market equipped with light-emitting elements and light guides, so that the light emitted by the light-emitting elements can be guided through the light guide to produce special visual effects.

[0003] It is common knowledge that the light guide of a cooling fan is directly fixed to the fan frame. Therefore, once the user gets tired of it or loses interest, it becomes impossible to replace it with another light guide, preventing the user from freely changing the light guide according to their own preferences. This is one problem. In addition, nowadays, users can only spend money to buy other cooling fans that already have the required light guide fixed in order to get the light guide they currently like. This not only incurs extra costs, but users also have to go through the trouble of removing the old cooling fan and then installing the new one, which is obviously troublesome and inconvenient. This is another problem.

[0004] Therefore, how to improve upon the shortcomings of the aforementioned prior technologies is a major issue that the creator of this application urgently needs to address. Utility Model Content

[0013] Furthermore, the front frame edge is also provided with at least one bridge, the groove has two groove walls, the bridge crosses the two groove walls of the groove, and at least one of the first magnetic attraction elements or at least one of the second magnetic attraction elements is embedded in the bridge.

[0014] Furthermore, at least one of the bridges is suspended within the trench and spans between the two trench walls.

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

[0065] The detailed description and technical content of this application are illustrated below with reference to the accompanying drawings. However, the accompanying drawings are provided for reference and illustration only and are not intended to limit this application.

[0066] This application provides a cooling fan with an easily replaceable light guide, allowing users to freely replace the light guide with their preferred one. For example... Figures 1 to 6 The first embodiment is shown below. Figures 7 to 8 The following is a second embodiment.

[0067] like Figures 1 to 6 As shown, the cooling fan with an easily replaceable light guide component (hereinafter referred to as the cooling fan) of this application includes: a fan frame 1, a fan wheel 2, a light-emitting module 3, a light guide component 5a, and a magnetic suction component 4.

[0068] The fan frame 1 has two opposing surfaces, one of which is defined as an air inlet surface 11 for drawing in air, and the other surface is defined as an air outlet surface (not shown) for discharging air. The fan frame 1 also has an internal space 19 (see...). Figure 5 ) and a front frame edge 111 surrounding the corresponding frame space 19, and the front frame edge 111 is as follows Figure 1 The component shown is located on the air inlet surface 11, while the rear frame edge (not indicated) opposite to the front frame edge 111 is located on the air outlet surface. In addition, a light-emitting module 3 is provided on the fan frame 1 corresponding to the front frame edge 111.

[0069] It should be noted that a carrier 14 may also be mounted within the space 19 of the fan frame 1. A shaft connection structure 141 is erected vertically on the carrier 14, and a main circuit board 15 is also mounted on the carrier 14. The fan wheel 2 may include a hub 21 and a plurality of fan blades 22 connected to the periphery of the hub 21. The hub 21 is provided with a spindle 211. The fan wheel 2 rotates relative to the fan frame 1 within the space 19 by connecting the spindle 211 to the shaft connection structure 141. Figure 5As shown, the fan wheel 2 has an axial direction D1 defined around the spindle 211, and a radial direction D2 perpendicular to the axial direction D1 is also defined. When the fan wheel 2 rotates relative to the fan frame 1, it can draw in outside air from the air inlet surface 11 along the axial direction D1, and discharge air from the air outlet surface along the axial direction D1.

[0070] The cooling fan of this application further includes a stator assembly S and a rotor assembly R. The stator assembly S is disposed corresponding to the shaft connection structure 141 and electrically connected to the main circuit board 15, while the rotor assembly R is disposed on the inner periphery of the hub 21 and surrounds the stator assembly S.

[0071] The light guide 5a is correspondingly disposed on the front frame edge 111, so that the light emitted by the light-emitting module 3 can enter along the axial direction D1 and penetrate the light guide 5a and be guided by the light. Figure 2 As shown, the light guide 5a has an entrance edge 511 and multiple exit edges (component symbols not indicated). The entrance edge 511 allows light to enter, and each exit edge allows light to exit. It should be noted that the light guide 5a can be a one-piece molded ring-shaped light guide ring 51 (e.g., Figure 1 and Figure 2 As shown in the figure, it can also be a modular structure containing at least two light guide strips (not shown in the figure) and each light guide strip can be combined to form a light guide ring (which can be correspondingly set on the front frame edge 111). This application does not limit this, but in this embodiment, the integrally formed light guide ring body 51 is used as an example for description.

[0072] The magnetic attraction component 4 includes at least one first magnetic attraction element 41 and at least one second magnetic attraction element 42 that can magnetically attract each other. This application does not limit the number of the first magnetic attraction element 41 and the second magnetic attraction element 42, but in this embodiment, a plurality of each is used as an example for description. Each first magnetic attraction element 41 (or each second magnetic attraction element 42) is disposed at intervals on the front frame edge 111, and each second magnetic attraction element 42 (or each first magnetic attraction element 41) is correspondingly disposed on the light entrance edge 511 of the light guide 5a.

[0073] To ensure that the light-emitting module 3 does not obstruct the magnetic attraction component 4, a groove 12 is formed on the front edge 111 of the fan frame 1. Two groove walls 121 and a... Figure 5 A groove bottom 122 is shown connecting the lower edges of the two groove walls 121. Thus, at least one bridge 13 is provided on the front edge 111 of the fan frame 1. It should be noted that this application does not limit the number of bridges 13 provided; in this embodiment, a plurality of bridges 13 are used as an example for explanation. Each first magnetic element 41 (or each second magnetic element 42) is provided on each bridge 13, and each second magnetic element 42 (or each first magnetic element 41) is positioned at the light-receiving edge 511 corresponding to the position of each bridge 13.

[0074] likeFigure 1 , Figure 5 and Figure 6 As shown, specifically, each bridge 13 is suspended between the two trench walls 121 within the trench 12, forming a channel W between each bridge 13 and the trench bottom 122, which is more conducive to the placement of the light-emitting module 3. Because the light-emitting module 3 includes a light-emitting circuit board 31 and a plurality of light-emitting elements 32 (which may be light-emitting diodes) disposed on the light-emitting circuit board 31, and the shape of the light-emitting circuit board 31 corresponds to the shape of the trench 12 (which may be annular), when the light-emitting circuit board 31 is placed within the trench 12, it can be placed at the trench bottom 122 by passing through each channel W. All the light-emitting elements 32 emit light along the axial direction D1 towards the light-incident edge 511 within the trench 12. Of course, the light-emitting elements 32 can avoid being directly below each bridge 13.

[0075] In this way, such as Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the second magnetic elements 42 and the first magnetic elements 41 are magnetically attracted to each other along the axial direction D1, so that the light guide 5a is detachably attracted and positioned on the front edge 111 of the fan frame 1. This allows the light irradiated by the light-emitting module 3 to enter the light-in edge 511 and then exit from the light-out edge, thus guiding the light irradiated by the light-emitting module 3 through the light guide 5a. When the user wants to replace a different light guide 5a, they can easily remove the original light guide 5a by applying an external force slightly exceeding the magnetic attraction force to the original light guide 5a already attached to the fan frame 1. Then, by bringing the new light guide 5a closer to the front edge 111, the first magnetic elements 41 and the second magnetic elements 42 will automatically magnetically attract each other, thereby attaching the new light guide 5a to the fan frame 1. This achieves the purpose and effect of easily and freely replacing the light guide 5a that the user prefers.

[0076] In order for the light guide 5a to be stably attached to the front frame edge 111, in addition to the surface of each bridge 13 not protruding (e.g., flush with) the front frame edge 111, it is also necessary to... Figure 2 As shown, a plurality of recesses 5111 are formed on the light-incident edge 511 of the light guide 5a. Each second magnetic element 42 is embedded in each recess 5111 and forms an exposed surface (element symbols not shown), and the exposed surface of each second magnetic element 42 is flush with the light-incident edge 511; similarly, as Figure 5As shown, a recessed hole can also be opened on each bridge 13, and each first magnetic element 41 is embedded in the recessed hole to form an exposed surface (the element symbol is not shown), and the exposed surface of each first magnetic element 41 is flush with the front frame edge 111. In this way, the light-incident edge 511 of the light guide 5a can be flat against the front frame edge 111 face to face, so that the light guide 5a is stably attracted to the front frame edge 111.

[0077] To ensure that the adsorbed light guide 5a has radial limiting on D2, such as Figure 1 , Figure 3 and Figure 4 As shown, the cooling fan of this application also includes a plurality of limiting blocks 18. Each limiting block 18 can be disposed on the outer periphery of the fan frame 1, so that each limiting block 18 surrounds the front frame edge 111. At the same time, the height of each limiting block 18 must be higher than the front frame edge 111, so that the light guide 5a can be limited by each limiting block 18 in the radial direction D2.

[0078] Furthermore, this application does not limit the adsorption type of the first magnetic element 41 and the second magnetic element 42, as long as they can magnetically attract each other. For example, the first magnetic element 41 and the second magnetic element 42 can be a permanent magnet and a metal, respectively; or conversely, the first magnetic element 41 and the second magnetic element 42 can be an electromagnet and a metal, respectively; or even the first magnetic element 41 and the second magnetic element 42 can be two permanent magnets of opposite polarities. In other embodiments not shown in the figures, the first magnetic element disposed on the fan frame 1 can also be an electromagnet.

[0079] like Figures 7 to 8 As shown, this is the second embodiment of the cooling fan of this application. The second embodiment is largely the same as the first embodiment, except that its light guide 5b is different from that of the first embodiment.

[0080] The light guide 5b in the second embodiment can also be a light guide ring 55 integrally formed into a ring shape. The light guide ring 55 also has a light-incident edge 551, a first light-outceasing edge 552, and a plurality of second light-outceasing edges (not labeled with component symbols), and the light-incident edge 551 and the first light-outceasing edge 552 are opposite to each other. The light-incident edge 551 is provided with the aforementioned second magnetic attraction elements 42, and the first light-outceasing edge 552 has a plurality of spaced-apart cuts 57, and a body 56 is formed between any two adjacent cuts 57.

[0081] By utilizing the blocks 56 and cutouts 57 of the light guide 5b, a light guiding effect that is different from and better than that of the first embodiment is produced.

[0082] In summary, the cooling fan with an easily replaceable light guide component in this application can indeed achieve the intended use and effect, and can solve the shortcomings of the prior art. Therefore, this patent application is filed.
