Dustproof cabinet, dustproof method and computer

Abstract

The invention provides a dustproof chassis, a dust removing method and a computer; the dustproof chassis comprises a dustproof net provided on the vent of the chassis; an emitter provided on one side of the dustproof net fro emitting the beam passing through the dustproof net; a receiver provided on the other side of the dustproof net for receiving the beam emitted by the emitter; a detector for detecting the strength of the beam receive by the receiver; a controller for ensuring the dust thickness of the dustproof net and adopting the dust suppression according to the strength of the beam receive by the receiver. The invention has function of dust prevention and dust measuring; when the system detects that there are too much dust on the dustproof net, it will pops the dustproof net and notifies the users to clear by alarm lamp, buzzer and other manners.

Description

technical field [0001] The invention relates to dust detection technology, in particular to a dust-proof chassis, a dust-proof method and a computer for detecting the dust condition of the dust-proof net of the chassis. Background technique [0002] Most of the existing computers use fans to dissipate heat from heating devices such as power supplies, CPUs, and graphics cards. This requires the computer case to have good air circulation, so the computer case is provided with vents. Inside the chassis, the air vents of the existing computer all need to be dust-proof. The following are two dust-proof designs in the prior art: [0003] In prior art 1, a filter screen is added to the air inlet of the chassis, and movable louvers are added to the air outlet to prevent dust. [0004] The second prior art is to prevent dust by designing an airtight case, which is completely closed when the computer is not in operation. [0005] There is following defective in above technology: ...

AI Technical Summary

Problems solved by technology

[0006] 1. In the prior art, dust-proof nets or shutters are simply installed. With the long-term use or long-term placement of computers, thick dust will accumulate on the dust-proof nets or shutters, which not only seriously affects the circulation of cooling air, but also accumulates Dust easily enters the inside of the computer and may cause short circuits and aging of components

[0007] 2. The dust-proof structure of the prior art 2 is relatively complicated, and it can only be completely dust-proof when the computer stops running. It cannot be completely closed when the computer is running, and the vents will still accumulate dust.

[0008] 3. The existing technologies only provide a dust-proof structure, but do not provide a means of detecting dust and a method of prompting the user to clean up
