Description
Technical field
The present invention relates to computer hardware equipment technical fields, and in particular to computer dedusting keyboard.
Background technique
Keyboard, is the input equipment of instruction and data and the peripheral hardware hardware of computer, can be right by the operation to keyboard
Computer carries out instruction input, so that computer is normally worked, therefore particularly important to the daily maintenance of keyboard.
In the long-term use process of keyboard, keyboard has certain electrostatic, and electrostatic can adsorb the adherency of the dust in air
On the key of keyboard, and since the gap between key is smaller, it is difficult to clear up the dust on key, to by dust
Cleaning then needs to disassemble key from keyboard completely, so necessarily will increase the workload of keyboard cleaning.
There are two types of the existing modes to keyboard protection, one is covering thin film on keyboard so that dust without
Method is directly adhered on key or keyboard, but due to there is the barrier inconvenience operator of film to use keyboard, and film
It is not durable, during long-term key tap, film is easily damaged.Another way is to make a lid to keyboard,
Keyboard is when not in use by cover closing, to have the function that keyboard when not in use will not adhering dust.But keyboard was using
Cheng Zhong still has dust to be adhered on keyboard, therefore bad using the effect of cover for protecting keyboard, is also not easy to carry out keyboard
Dedusting.
Summary of the invention
The invention is intended to provide a kind of computer dedusting keyboard that can carry out fast dust-removing to keyboard, to improve keyboard
Efficiency of dust collection.
In order to achieve the above objectives, the technical scheme is that：Computer dedusting keyboard, including keyboard body and be mounted on
Several keys on keyboard, the two sides of keyboard body are respectively fixed with support base；
The keyboard body is equipped with air cavity corresponding with key and the piston plate that is slidably connected with air cavity, sets on piston plate
There is the piston rod being fixedly connected with key, piston plate bottom is fixed with the spring to offset with keyboard body, and the bottom of air cavity is equipped with
Outgassing nonreturn valve and the first breather check valve being connected to the outside of air cavity；
The air amplifier and gas tank being connected to outside are wherein fixed in the support base of side, gas tank passes through solenoid valve and sky
The annular chamber of gas amplifier is connected to, and gas tank is equipped with the second breather check valve being connected to outgassing nonreturn valve；
It is additionally provided with several with the external dust removing tube being connected in the keyboard body, dust removing tube includes several dedusting sections, described
Dedusting section includes contraction section, diffuser and the trunnion for being connected to contraction section and diffuser, and trunnion is equipped with the gas being connected to dedusting section
Pipe, tracheae are connected to the upper surface of keyboard body, and the outlet side of air amplifier is connected to dust removing tube.
The principle of the present invention and beneficial effect：During operator uses keyboard, keyboard body is easy to happen position
Offset is set, operator needs that constantly the position of keyboard is adjusted, and the experience that keyboard uses is influenced very much, by key
The two sides setting support base of disk stablizes keyboard body, reduces the possibility of keyboard offset.
When operator uses keyboard, finger pressing keys, key can push down on piston rod, and piston rod can squeeze
Piston plate and spring are pressed, so that piston plate squeezes the gas in air cavity, and gas can pass through outgassing nonreturn valve, the second air inlet list
It enters in gas tank and is accumulated to valve.When gas in gas tank is stacked into a certain amount and forms high pressure gas, electromagnetism is opened
Valve, the gas in gas tank are entered in air amplifier by solenoid valve and annular chamber, and air amplifier work sucking is a large amount of
Outside air, and a large amount of air is drained into dust removing tube by air amplifier.Gas can pass through dedusting section, and gas is from contraction
Section enters and gas is discharged from diffuser, so that trunnion will form negative pressure, under the action of negative pressure, trunnion section can pass through gas
Dust is drawn into dedusting section by pipe, as gas is discharged, is so dusted to keyboard.Compared with traditional keyboard, this
Scheme presses key by operator, to form high pressure gas in gas tank, makes air by high pressure gas
Amplifier works, and the cooperation of air amplifier and dust removing tube is dusted, and so may be repeated dedusting work, than using
Film is compared, more save the cost, compared with using lid, can be more directly effectively dusted to keyboard.
Further, dust excluding plate is equipped between two neighboring key, the bottom of dust excluding plate, which is fixed with to slide with keyboard body, to be connected
The drive rod connect, drive rod bottom are fixed with the air bag being connected to piston plate top air cavity.In keyboard in use, spring will push
Piston plate upward sliding, the gas in the air cavity of piston plate top can be expressed in air bag, and air bag inflation can expand, thus gas
Capsule will push drive rod, and drive rod pushes dust excluding plate upward sliding so that dust excluding plate by the position between two keys into
Row closing, key is blocked in the lower section for avoiding bulky grain dust etc. from falling to key.
Further, the outlet side of air amplifier is communicated with multi-pass pipe, and multi-pass pipe is connected to dust removing tube.Pass through multi-pass pipe
Dust removing tube is connected to, air amplifier simultaneously blows to more dust removing tubes.
Further, pressure sensor is installed, pressure sensor is electrically connected with controller, and controller is electrically connected in gas tank
LED light, solenoid valve are electrically connected with the controller.Air pressure in gas tank reaches a timing, and pressure sensor can send pressure signal
To controller, it is sufficient that controller can control the luminous pressure carried out in warning gas tank to operator of LED light, while controller is also
Solenoid valve opening can be controlled, so that the high pressure gas in gas tank enters in annular chamber.
Further, dust excluding plate is equipped with spongy layer.It can stop bulky grain by dust excluding plate, the spongy layer on dust excluding plate can
Dust is adsorbed, dust is avoided to enter the lower section of key from the gap between equation plate and key.
