Description

Technical Field

[0001] The utility model relates to the field of dust removal for computer fans, in particular to a dust removal device for computer fans. Background Art

[0002] The components of a computer include a host, a display screen, etc. The server inside the host is composed of multiple circuit boards and electronic components. Under continuous operation, a large amount of heat will be generated. The heat accumulates in the host and covers the server, causing the computer to run slowly and malfunction over time. Therefore, cooling fans are installed in almost all computer hosts.

[0003] Computer hosts are usually physically stationary and fixed, and some dust will accumulate inside and outside for a long time. The cooling fan is no exception. The more dust accumulated on the fan, the more it will affect its use effect to a certain extent. It needs to be dusted and cleaned periodically. Generally, the cooling fan is installed inside the host. To clean it, the host needs to be disassembled and the fan needs to be removed. This process is undoubtedly tedious and complicated, and ordinary people are generally unfamiliar with the disassembly and assembly of computer hosts. Frequent disassembly of computer hosts will also cause a certain degree of damage to the computer server. Therefore, a dust removal device for computer fans is needed. Utility Model Content

[0004] 1. Technical Problems Solved

[0005] The technical problem to be solved by the utility model is that when dust removal is performed on a computer fan, the computer host needs to be disassembled and assembled, which is relatively cumbersome and complicated, and may cause certain damage to the computer host itself.

[0013] 3. Beneficial Effects

[0014] The advantage of the utility model over the prior art is that the device is equipped with a telescopic frame structure on the traditional computer cooling fan.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Embodiment 1

[0023] Combined with Figure 1-3 In order to solve the above technical problems, the technical solution provided by the utility model is as follows: a dust removal device for a computer fan, comprising a base 1, wherein both ends of the base 1 are connected outwardly with a plurality of support ears 2 with fixed holes, so that the device can be fixed in a computer host through the base 1, and a fan mechanism is connected to one side of the base 1, wherein the fan mechanism comprises an exhaust fan 16, wherein a transmission shaft 18 matched with the exhaust fan 16 is rotatably connected in the fan mechanism, and a fan motor 17 matched with the transmission shaft 18 is connected in the fan mechanism.

[0024] The fan mechanism mainly consists of a rotating exhaust fan 16, which is used as a computer fan to exhaust air for heat dissipation of the computer host server. When the fan motor 17 is running, the transmission shaft 18 is driven to rotate, and the exhaust fan 16 composed of multiple propeller blades is rotated, thereby allowing air to circulate inside and outside the computer server for heat dissipation.

[0025] Embodiment 2

[0026] Combined with Figure 1-5A mounting frame 15 is connected to one side of the base 1, and the fan mechanism is arranged in the mounting frame 15. A plurality of fixed ends 19 cooperating with the mounting frame 15 are connected at both ends of the fan mechanism, and a fan mechanism with a computer exhaust fan 16, etc. is fixed on the mounting frame 15. A plurality of telescopic rods 14 are rotatably connected between the base 1 and the mounting frame 15. A support block 12 and a support block 2 13 are connected at both ends of the base 1 and the mounting frame 15. The support block 12 and the support block 2 13 are rotatably connected with the two ends of the telescopic rod 14. A screw sleeve 6 is rotatably connected to one side of the base 1 close to the mounting frame 15. A support frame 5 cooperating with the screw sleeve 6 is connected to one side of the base 1 for supporting the screw sleeve 6 on the base 1. The base 1 is located above the screw sleeve 6 A power shaft 3 is rotatably connected, and a driving motor 4 that cooperates with the power shaft 3 is connected to one side of the base 1 to provide power for the power shaft 3. A worm gear transmission mechanism 7 is commonly connected between the power shaft 3 and the sleeve, and a threaded shaft 8 is rotatably connected in the sleeve 6. A limit plate 9 is connected to the end of the threaded shaft 8 away from the support rod 10 to provide a position limit for the movement of the threaded shaft 8. A support rod 10 that cooperates with the telescopic rod 14 is connected between the base 1 and the mounting frame 15, and support shafts 11 that cooperate with the center position of the telescopic rod 14 are connected at both ends of the support rod 10, so that the telescopic rod 14 can keep moving at both ends of the support rod 10 while also serving as a power guide for transmitting the threaded shaft 8 after the position of the threaded shaft 8 moves. One end of the threaded shaft 8 is connected to the support rod 10.

[0027] When the driving motor 4 is running, it provides power support for the rotation of the power shaft 3, and under the action of the worm gear transmission mechanism 7, the screw sleeve 6 on the base 1 rotates synchronously with the power shaft 3, and at the same time, the threaded shaft 8 in the screw sleeve 6 moves inside and outside the base 1, thereby driving the support rod 10 to move. Under the auxiliary action of the telescopic frame composed of multiple telescopic rods 14, the mounting frame 15 carrying the exhaust fan 16 on one side is further moved outside one side of the base 1. In the telescopic mechanism design with multiple telescopic rods 14 and threaded shaft 8 as the main body, a support block 12 and a support block 2 13 are respectively provided on both sides of the base 1 and the mounting frame 15, and the support blocks 12 and 13 on the base 1 and the mounting frame 15 are staggered with each other. There are two telescopic rods 14 located at one end of the support rod 10, and they are grouped into an X shape. Each telescopic rod 14 is connected to a support block 12 and a support block 2 13 at both ends, which facilitates the operation of the telescopic structure.

[0028] When the utility model is implemented in a specific way, when using the computer fan dust removal device, the device is installed in the exhaust port of the computer host through the supporting ears 2 on the base 1, and the exhaust fan 16 is still located on the inner side of the heat dissipation port. When the computer fan needs to be dusted, the baffle or filter plate at the heat dissipation port of the computer host is punched or removed. It should be noted that the space at the heat dissipation port of the host needs to be sufficient for the fan mechanism and the mounting frame 15 in the device to pass through. Under the operation of the driving motor 4 and the action of a series of transmission mechanisms, the threaded shaft 8 moves in the device against the support rod 10, and the telescopic mechanism supported and connected between the base 1 and the mounting frame 15 is started to operate, and the mounting frame 15 carrying the exhaust fan 16 and the fan mechanism is pushed out from the heat dissipation port of the circuit host, so that the fan mechanism as the computer fan can be easily accessed without disassembling the host shell. In the future, whether it is to directly perform simple dust removal on the exhaust fan 16 or to disassemble the fan mechanism as a whole for cleaning, it is relatively easy. Without directly disassembling the entire host, it can also play a certain protective role in the use of the computer.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
