Abstract
A keyboard is prepared as setting circuit and 16-120 keys in casing, coating photo catalyst layer on external surface of casing and on external surface of each key. The thickness of photo catalyst layer is 5-300nm and it is prepared by titanium dioxide particles, the bacteriovirus attached on keyboard can be sterilized by photo catalyst when photo catalyst is shined by ultraviolet ray in enviroment light and lamp light.
Description
Technical field
The present invention relates to computing machine, relate in particular to the input equipment of computing machine, particularly keyboard, concrete is a kind of keyboard.
Background technology
In the prior art, computing machine is located generally to use as library, Internet bar etc. in public, and these occasion flows of the people are big, the frequency of utilization height of computer keyboard, dirts such as sweat are adhered on the surface of keyboard and button thereof easily, very easily grow and spread germs, and are very unhygienic.
Summary of the invention
The purpose of this invention is to provide a kind of keyboard, described this keyboard will solve the technical matters that the keyboard of public arena in the prior art grows easily and spreads germs.
This keyboard of the present invention is made of housing and circuit, described circuit is arranged in the described housing, be provided with 16 to 120 buttons in the described housing, wherein, be coated with the photo-catalytic coating layer on the outside surface of described housing, be coated with the photo-catalytic coating layer on the outside surface of any one described button.
Further, the thickness of described photo-catalytic coating layer is between 5～300nm.
Further, described photo-catalytic coating layer is made up of titanium dioxide granule.
The present invention and prior art compare, and its effect is actively with tangible.The present invention is provided with photo-catalytic coating on the outside surface of keyboard.Because the energy that photo-catalytic coating can utilize light to provide carries out catalytic action, produce electric charge under the ultraviolet ray irradiation in sunshine or lighting source, react with airborne hydrone and oxygen molecule, produce negative oxygen ion and hydroxyl free radical, these materials have superpower oxidability, can destroy the cell membrane of bacterium, tenuigenin is run off and death, can also solidify the protein of virus, suppress the activity of virus, and catch airborne various planktonic bacteria.The present invention utilizes ultraviolet ray and the ultraviolet ray in the lighting light source in the ambient lighting that the photo-catalytic coating layer is shone, can be to killing attached to the bacterial virus on the keyboard.
Description of drawings
Fig. 1 is the structural representation of keyboard of the present invention.
Embodiment
As shown in Figure 1, keyboard of the present invention, constitute by housing 1 and circuit, described circuit is arranged in the described housing 1, be provided with 16 to 120 buttons 2 in the described housing, wherein, be coated with the photo-catalytic coating layer on the outside surface of described housing 1, be coated with the photo-catalytic coating layer on the outside surface of any one described button 2.
Further, the thickness of described photo-catalytic coating layer is between 5～300nm.
Further, described photo-catalytic coating layer is made up of titanium dioxide granule.
Claims (3)
