The utility model has the advantages that the dust-proof frame with the filter screen is additionally arranged on the air inlet side of the original computer fan, and dust is blocked by the filter screen and accumulated on the filter screen, thereby greatly reducing the dust adhered to the fan and entering the case; the dustproof frame is easy to disassemble and assemble and convenient to clean; each fan can be provided with the dustproof frame corresponding to the size of the fan, and the fan is suitable for popularization.

Description

Computer Fan Dustproof Stand

technical field

The utility model relates to the technical field of computers, in particular to a computer fan dust-proof frame. the

Background technique

At present, the fans known in the market are assembled on the chassis. Users generally place the chassis against the wall, corners, inside the chassis cabinet, etc. where dust is easy to accumulate. The working principle of the chassis fan is to use the rotation of the fan to form a negative It draws the air outside the case into the inside of the case to promote the heat exchange of heating elements, so that the hardware can work normally. Therefore, after a period of use, a large amount of dust flowing with the air accumulates on the fan frame and fan blades, resulting in The air volume of the fan is weakened and the service life of the fan is shortened; on the other hand, the dust will also enter the chassis with the air and deposit on the hardware, which is very easy to cause damage to the components of the motherboard and the slots on the motherboard, CPU, etc. impact, thereby reducing the working efficiency of the whole machine, shortening the service life of each hardware, or even breaking down; and when cleaning the dust on the fan frame and fan blades, the fan must be removed from the chassis and then cleaned with a brush, which is troublesome to operate. This also directly causes many users to give up the cleaning work of the fan. the

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a computer fan dust-proof stand that is easy to disassemble and clean. the

The utility model is realized through the following technologies. The dust-proof frame is composed of a bracket and a filter screen, the filter screen is fitted in the placement groove of the bracket, and the middle part of the placement groove has a hollow ventilation hole; the bracket is connected with the fan in a snap-fit manner; handle. The bracket is fixed by a post inserted into the fan screw counterbore. the

The utility model has the advantage that a dust-proof rack with a filter screen is installed on the air inlet side of the original computer fan, and the dust is blocked by the filter screen and accumulated on the filter screen, thereby greatly reducing the dust adhering to the fan and entering the chassis ;The dust-proof frame is easy to disassemble and easy to clean; each fan can be equipped with a dust-proof frame corresponding to its size, which is suitable for promotion. the

Detailed ways

Embodiments of the present utility model will be further described below in conjunction with the accompanying drawings, as shown in Figures 1 to 3, the dust-proof frame 1 includes a support 11 and a filter screen 12, and the filter screen 12 is fitted in the placement groove 113 of the support 11, There is a hollow ventilation hole 114 in the middle of the placement groove 113 ; the bracket 11 is snap-fit connected with the fan 2 ; the bracket 11 is fixed by a column 111 inserted into the screw hole of the fan 2 ; the bracket 11 has a handle 112 . the

First fit the filter screen 12 in the placement groove 113 of the bracket 11 movable or fixedly, complete the assembly of the dustproof frame 1, install the fan 2 on the chassis 3, and then align the column 111 on the bracket 11 with the screw of the fan 2 The counterbore can be snapped together by pressing slightly firmly to complete the assembly. When in use, the airflow enters the interior of the chassis 3 through the ventilation hole 114 under the negative pressure generated by the action of the fan 2, while the dust is blocked by the filter screen 12 on the dustproof frame 1, thereby ensuring that the dust will not affect the fan 2 and other hardware . When it is necessary to clean the dust-proof frame 1, as long as the handle 112 on the bracket 11 is pressed by hand, and slightly forcefully pulled outward, the dust-proof frame 1 can be taken off for cleaning; after cleaning the bracket 11 and the filter screen 12, the The column 111 is slightly pressed against the screw counterbore of the fan 2, and the column buckle 111 is fastened on the fan 2; compared with the screw-in assembly scheme, the buckle-fit assembly scheme can make the dustproof frame 1 more stable during disassembly and assembly. For simplicity and convenience. the
