Description

Dust removal type keyboard for electronic product
Technical Field
The invention relates to the technical field of electronic products, and particularly discloses a dust-removal keyboard for an electronic product.
Background
The computer keyboard is an important input channel for inputting the control information of the character information into the computer. After a common desktop computer keyboard is used for a long time, a large amount of dust is easily accumulated in the keyboard, and particularly, the dust in a gap of the keyboard is difficult to clean.
Chinese patent document cn104808805B discloses a friction type electrostatic dust collection keyboard, which comprises a keyboard upper cover, a keyboard lower cover, friction cloth and a friction plate, wherein the keyboard lower cover comprises a keyboard working element, a key position column and a side hole. Static electricity is generated by friction between the friction plate and the friction cloth, so that dust in a gap of the keyboard cap is adsorbed on the friction plate and then is pulled out of the friction plate for cleaning.
Although the above patent document solves the problem that the dust inside the gap of the keyboard cap is difficult to clean, the following problems still exist: after static electricity is generated by friction between the friction cloth and the friction plate, the static electricity of the two substances can attract electrons outside the core, so that dust is easily adsorbed on the friction cloth, and the dust is remained on the keyboard shell and is not cleaned up.
Disclosure of Invention
This scheme is anticipated is providing a dust type keyboard for electronic product to after friction produces static among the solution prior art between friction cloth and the friction plate, both can produce the atomic nucleus, lead to the dust to adsorb easily and not shift out along with the friction plate on the friction cloth, make and remain the dust and remain the problem that the clean up is not left on the keyboard shell.
A dust type keyboard for electronic product in this scheme, including keyboard shell, key cap, key position post, keyboard lower cover and dust collector, keyboard shell upper surface is equipped with the key position post, and the key cap passes through the key position post to be installed at keyboard shell upper surface, lead to the groove and locate keyboard shell bottom surface, lead to groove and side opening intercommunication, the key cap passes through the key position post to be installed on the keyboard shell between the adjacent groove that leads to, there is the friction cloth adjacent to lead to the keyboard shell inside wall between the groove, dust collector includes handheld portion, friction lever, metal block, friction lever one end and handheld portion fixed connection, the other end is connected with the metal block.
Hold handheld portion, make dust collector pass through the side opening entering of keyboard shell, friction lever on the dust collector meeting and adjacent keyboard shell inner wall side of leading to between the groove are provided with the friction cloth contact, the metal block on the friction lever can be located the gap department that sets up between adjacent key cap, remove handheld portion among leading to the groove, friction lever and friction cloth friction this moment produce static, produce the atomic nucleus, the metal block leading-in current who is connected with friction lever one end produces static, can make the metal block attract key cap and keyboard shell's gap department dust this moment. The dust is adsorbed on the metal block, and then the dust removing device is drawn out from the side hole to take the dust out, so that the dust cleaning effect is achieved.
Compared with the prior art, the scheme has the advantages that:
1. the setting up of metal block makes the dust can not fall into friction cloth or other positions, but directly makes the dust adsorb on the metal block, after friction produced static between friction cloth and the friction plate among the solution prior art, both can produce static, lead to the dust to adsorb easily and do not shift out along with the friction plate on the friction cloth, make and remain the dust and remain in the problem of not clean up in the keyboard.
2. The setting that leads to the groove can not only make dust collector remove the clearance dust, when water accident drips on the keyboard, leads to the groove and can make rivers play the function of drainage.
Furthermore, the through groove and the side hole communicating part are rotatably connected with a plurality of rotating rollers, the distance between every two adjacent rotating rollers is smaller than 2-5 mm of the length of the metal block, and the rotating rollers are wrapped with cleaning cloth.
Lead to groove and side opening intercommunication swing joint have a plurality of live rollers of wrapping up the washing cloth, when taking dust collector out from the side opening, because the distance between the live roller is less than 2mm ~ 5mm of metal block length, can produce extrusion friction to the metal block surface between the live roller, the metal block can be wiped to the washing cloth on the live roller, clearance metal block absorbent dust. The cleaning of the metal blocks is realized, the rotating roller is cleaned without cleaning the dust removing device after dust removal every time, and the dust removing and cleaning efficiency is improved.
Further, the friction rod is a rubber rod, the friction cloth is fur cloth, and the metal block is a silver block. The friction rod and the friction cloth are made of different materials to generate different atomic nuclei, and the silver block is better in conductivity than other metals, so that the silver block is easier to adsorb dust.
Further, the thickness of the metal block is 0.3-0.7 times of the height between the keycap and the keyboard shell.
Make the metal block not with key cap part direct contact down, overcome prior art and compare the direct production contact of clutch blocks and key cap, use the keyboard messenger can influence the problem that the operation was felt.
Further, the keyboard is provided with a containing part for containing the dust removing device, and the containing part is a containing box arranged on one side of the keyboard.
The dust-proof device is placed in the containing box without the dust-proof device, and the dust-proof device is taken out of the containing box during use.
Further, a magnet is arranged on one side of the keyboard, and a magnet is arranged on the handheld portion.
Can prevent to drop at will and put dust collector, find dust keeper fast.
Further, the key cap is movably mounted on the key position column.
When one or more of the keycaps are damaged, the keycaps are removed and replaced with intact keycaps, and maintenance costs are saved by replacing damaged keycaps individually as compared to mounting the keycaps in a key post without deactivation.
