Computer dust filtering and ventilation device

Abstract

A computer dust filtering and ventilation device including a case, one side wall of the case is provided with an air inlet, one side of the air inlet is provided with a first connecting pipe connectedwith the case, the first connecting pipe is communicated with the air inlet, the first connecting pipe is connected with a second connecting pipe at one end away from the case, A first dust filteringmechanism is arranged inside the second connecting pipe, A second dust filtering mechanism is arranged inside the first connecting pipe, the first dust filtering mechanism comprises a filter screen installed on the side wall of the top end of the second connecting pipe, a first fan connected with the side wall of the second connecting pipe is installed below the filter screen, and the second dustfiltering mechanism comprises a first electrode plate installed on the side wall of the top end of the first connecting pipe. The device can carry out double dust filtering on the dust, and has gooddust filtering effect, the filter screen is convenient to disassemble and clean, the traditional bolt fixation is replaced with clamping connection, the device is convenient for people to operate, andthe practicability is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a computer dust filtering ventilation device. Background technique [0002] A computer, commonly known as a computer, is a modern electronic computing machine used for high-speed computing. It can perform numerical calculations, logical calculations, and has storage and memory functions. It is a modern intelligent electronic device that can run according to the program and process massive data automatically and at high speed. [0003] During the use of the computer case, a dust-proof net is often installed on one side of the case, and the dust-proof net is used for dust filtering and ventilation. Since there is only a single-layer filter for dust filtering, the dust filtering effect is poor, and a lot of dust will still enter Inside the chassis, after a long time, the filter holes on the surface of the dust-proof net will be covered with a lot of dust, which will affect the ve...

[0003] During the use of the computer case, a dust-proof net is often installed on one side of the case, and the dust-proof net is used for dust filtering and ventilation. Since there is only a single-layer filter for dust filtering, the dust filtering effect is poor, and a lot of dust will still enter Inside the chassis, after a long time, the filter holes on the surface of the dust-proof net will be covered with a lot of dust, which will affect the ventilation effect, and the hot air inside the chassis usually flows upwards, and the dust-proof net on one side wall alone is used for ventilation. The effect is poor, for this reason, we propose a computer dust filter ventilation device
