Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with specific examples, but the implementation of the present invention is not limited thereto.
[0026] Such as Figure 1-Figure 8 As shown, the computer fan provided by the present invention includes an upper cover 1 , a lower cover 2 and fan blades 3 .
[0027] The upper cover 1 has a first frame 11 around it and a first fixing plate 12 in the middle; between the first fixing plate 12 and the first frame 11 is a ventilated first mesh structure 13, the first The mesh structure 13 is made up of a plurality of spokes; the inner side of the fixed plate 12 is fixed with a bearing 14; the inner ring of the bearing 14 is fixed with a first internal spline 15, and the first internal spline 15 can be connected with the bearing through a flat key 14 inner rings are fixed.
[0028] The lower cover 2 has a second frame 21 around it and a second fixing plate 22 in the middle; between the second fixin...

The invention discloses a computer fan. The computer fan comprises an upper cover, a lower cover and fan blades, first edges are arranged on the periphery of the upper cover, a first fixing plate is arranged in the middle of the upper cover, a ventilating first net structure is arranged between the first fixing plate and the first edges, a bearing is fixed on the inner side of the fixing plate, afirst internal spline is fixed to the inner ring of the bearing, second edges are arranged on the periphery of the lower cover, a second fixing plate is arranged in the middle of the lower cover, a ventilating second net structure is arranged between the second fixing plate and the second edges, a motor is fixed on the inner side of the second fixing plate, a second external spline is installed onan output shaft of the motor, a first external spline matched with the first internal spline is arranged at one end of a fan blade central shaft, the other end of the fan blade central shaft is provided with a second internal spline matched with the second external spline, the upper cover and the lower cover are fixedly connected through screws. Due to the fact that the computer fan assembly is formed by assembling the upper cover, the lower cover and the fan blades, when maintenance or sweeping is needed, the fan can be disassembled, and then maintenance and sweeping on an inner hidden portion can be facilitated.
Description
technical field [0001] The invention relates to the field of computer fans, in particular to a computer fan assembly which is easy to assemble and disassemble. Background technique [0002] At present, most of the computer fans on the market are integrated after leaving the factory, and disassembly is very troublesome, or even impossible to disassemble. Such computer fans have the following disadvantages: [0003] (1) When it is necessary to maintain, overhaul or clean the fan, since the fan is difficult to disassemble, it will cause certain troubles to the maintenance, overhaul and cleaning work; [0004] (2) When the fan blade of the fan is damaged and needs to be replaced, since the fan blade part cannot be replaced separately, it can only be replaced together with the casing as a whole, which will increase the maintenance cost. Contents of the invention [0005] Aiming at the above-mentioned shortcomings of the prior art, the technical problem to be solved by the pre...
