Description

Technical Field

[0001] The utility model relates to the field of cooling fans, in particular to a detachable fan device. Background Art

[0002] Cooling fans are usually fixed on electronic products. By blowing air towards the electronic products with the cooling fans, the air can take away the heat of the electronic products, thus achieving heat dissipation. For example, at least one cooling fan is fixed on one side of a graphics card.

[0003] Cooling fans often malfunction and need to be repaired. Even after being used for a period of time, they may be damaged and need to be replaced with new ones.

[0004] However, the known cooling fans are firmly fixed on electronic products. If repair or replacement of a new cooling fan is needed, users have to carry out cumbersome disassembly and installation work, which is troublesome and time-consuming, and has been criticized for a long time.

[0005] Therefore, how to solve the above problems is a major issue that the patent applicant of this patent urgently needs to solve. Summary of the Utility Model

[0029] The detailed description and technical content of the present application are described as follows in conjunction with the drawings. However, the drawings are only provided for reference and illustration, and are not intended to limit the present application.

[0030] The present application provides a detachable fan device, which is mainly applied to electronic products (such as graphics cards, etc.) that require maintenance and replacement of the fan from time to time. As Figures 1 to 4 is the first embodiment of the present application. As Figure 5Shown is the second embodiment.

[0031] The first embodiment,

[0032] As Figures 1 to 4 shown, this embodiment is used to be connected and conduct electricity with a power supply 8, and it includes: a fan module 100 and a combined seat structure 600. The fan module 100 is detachably installed on the combined seat 600. When it is necessary to repair or replace the fan module 100, the fan module 100 can be easily detached from the combined seat structure 600. It should be noted that the power supply 8 can be any object capable of supplying power to this fan device. For example, it can be the wire group 81 as shown in the figure, and one end of the wire group 81 (not shown in the figure) is connected to a power supply unit (not shown in the figure).

[0033] The combined seat structure 600 includes a seat body 6 and a first circuit board 7. All or a part of the first circuit board 7 is arranged on the seat body 6. In this embodiment, a part is arranged on the seat body 6 for illustration. Another part of the first circuit board 7 is connected and conducts electricity with one end of the wire group 81. A first electrical docking component 71 is arranged on this part of the first circuit board 7, and the aforementioned power supply unit can supply power to the first electrical docking component 71 via the wire group 81 and the first circuit board 7.

[0034] Specifically, the first electrical docking component 71 can be any component capable of electrically docking for power supply. In this embodiment, the spring pin connector 711 is taken as an example for illustration; a recessed part 61 is recessed on the seat body 6, and the part of the first circuit board 7 connected to the seat body 6 is arranged in the recessed part 61. The spring pin connector 711 is arranged on the first circuit board 7 corresponding to the recessed part 61, so that the spring pin connector 711 is accommodated in the recessed part 61.

[0035] The fan module 100 includes a fan wheel 1, a carrier 2 and a second circuit board 4. The fan wheel 1 is rotatably arranged on the carrier 2. Specifically, the fan wheel 1 includes a hub 11 and a plurality of fan blades 12. Each fan blade 12 is connected to the periphery of the hub 11, and a mandrel 111 is arranged on the hub 11; the carrier 2 is provided with a sleeve structure 21 (including a sleeve without marked component symbols and at least one bearing arranged in the sleeve), and the fan wheel 1 is rotatably inserted on the sleeve structure 21 with the mandrel 111. In addition, the carrier 2 is provided with a break 22 corresponding to the second electrical docking component 41, so that the second electrical docking component 41 can be electrically docked with the first electrical docking component 71 via the break 22.

[0036] The second circuit board 4 is arranged on the carrier 2, and a second electrical docking component 41 is arranged on the second circuit board 4 corresponding to the aforementioned first electrical docking component 71. Specifically, the second electrical docking component 41 can be any component capable of electrically docking with the first electrical docking component 71. In this embodiment, a plurality of gold fingers 411 are taken as an example for illustration.

[0037] The carrier 2 is detachably fixed on the seat body 6, and at the same time, the second electrical docking component 41 and the first electrical docking component 71 are electrically docked with each other, that is, the plurality of gold fingers 411 and the spring pin connector 711 are wire-docked with each other, so that the aforementioned power supply unit supplies power to the second circuit board 4 via the wire group 81, the first circuit board 7, the first electrical docking component 71 and the second electrical docking component 41, that is, the electricity of the power supply unit is supplied to the fan module 100 via the combined seat structure 600.

[0038] Specifically, the aforementioned hub 11 is further provided with a rotor assembly 32, the carrier 2 is provided with a stator assembly 31 surrounded by a corresponding sleeve structure 21, and the rotor assembly 32 surrounds the stator assembly 31, and the stator assembly 31 and the rotor assembly 32 together form a stator and rotor structure 3.

[0039] Thus, as Figures 1 to 4 shown, when maintenance or replacement is required, as long as the fan module 100 is detached from the combined seat structure 600, the fan module 100 can be repaired or a new fan module 100 can be replaced. Therefore, the wire group 81 does not need to be involved during maintenance, and when replacement is required, it is not necessary to replace the entire fan device. As long as the faulty or damaged fan module 100 is replaced, it has the effects of easy maintenance and no waste, that is, the fan module 100 can be easily detached and replaced from the combined seat structure 600.

[0040] Embodiment Two

[0041] As Figure 5 shown, this is Embodiment Two of the present application. Embodiment Two is generally the same as Embodiment One, and the only difference is that the installation positions of the first electrical docking component 7 and the second electrical docking component 41 are swapped with each other.

[0042] In Embodiment Two, the second electrical docking component 41 (which can be a plurality of gold fingers 411) is provided on the first circuit board 7 of the combined seat structure 600, and the first electrical docking component 71 (which can be a spring pin connector 711) is provided on the second circuit board 4 of the fan module 100. And Embodiment Two can also have all the effects of Embodiment One.

[0043] In addition, it should be noted that, as Figures 2 to 5As shown, the present application does not limit the structure of how the carrier 2 is detachably fixed to the seat body 6. For example, it can be a snap connection or a screw connection, etc. As shown in the figure, a plurality of first fixing parts 23 are provided around the carrier 2, and a corresponding plurality of second fixing parts 62 are provided around the seat body 6, so as to be respectively detachably fixed to each of the first fixing parts 23 and the second fixing parts 62 by a plurality of detachable fixing elements not shown in the figure. When it is desired to repair or replace the fan module 100, as long as the fixing elements are removed, the carrier 2 can be disengaged from the seat body 6.

[0044] In summary, the detachable fan device of the present application can indeed achieve the expected use purposes and effects, and can solve the deficiencies of the prior art.

[0045] The above is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. Therefore, all equivalent structural changes made by using the content of the specification and drawings of the present application are included in the scope of the rights of the present application. This is hereby stated.
