Abstract

The utility model discloses a negative ion key board, which comprises a keyboard shell and a keyboard control circuit and also comprises a negative ion generator which is electrically connected with the keyboard control circuit. The utility model uses a form that the negative ion generator is integrally combined with the keyboard, and can implement the air disinfection and sterilization by the negative ion to the keyboard and the periphery environments of other computers in requirement. The bacteria, the strange smell, the dust, etc. in the air can be removed, a favorable working environment can be created and the physical health of the human body can be protected.

Description

The negative ion keyboard

Technical field

The utility model relates to a kind of computer keyboard, relates in particular to a kind of negative ion keyboard.

Background technology

Keyboard is as the standard input device of computing machine, all will be used continually every day, today of popularizing in the internet particularly, keyboard almost is the highest equipment of frequency of utilization in the computer equipment, all frequently contact with people's hand every day, especially in some public occasions,, also to there be every day different people to contact same keyboard as Internet bar, office etc.Because staff will contact large numbers of items every day, has a large amount of bacteriums, sweat, greasy dirt etc. on hand, make that like this keyboard that frequently contacts with hand has also adhered to a large amount of harmful bacterias, as streptococcus, Escherichia coli and other germ.As everyone knows, using a computer for a long time can be because static, germ, dust, electromagnetic radiation etc. brings in various degree harm for people's health.The upright university of State of Arizona, US studies show that keyboard, mouse and touch-screen have become the viral source on the biological meaning, and parasitic harmful germ quantity is thereon Duoed 400 times than the germ in public lavatory.Germ on other computer hardware is very important too, as: display, main frame, mainboard, CD-ROM drive, mouse etc.The positive ion that each electric appliances in the environment, information articles for use and chemicals etc. produce is too much, influences the healthy of people, makes us producing uncomfortable.Therefore the improvement of computing machine surrounding enviroment, computing machine user surrounding environment quality and air quality has become more and more important, a more and more urgent problem.

The preventive medicine science studies have shown that anion concentration is a key of weighing the air quality quality in the air, and the negative ion of debita spissitudo has significant impact to people's health, longevity and ecologic environment in the air.Negative ion can be removed airborne bacterium, peculiar smell, dust etc., makes us can breathe pure and fresh air as the Nature.

Summary of the invention

The purpose of this utility model is at the problems referred to above, and a kind of negative ion keyboard is provided, can effectively improve environment and air quality, has started the computing machine user and has utilized healthy negative ion to protect the new ideas of self health.

In order to reach the foregoing invention purpose, the utility model has adopted following technical scheme: comprise a keyboard case, and a keyboard control circuit, also comprise an anion generator, be electrically connected with keyboard control circuit.

The form that the utility model adopts anion generator to combine with the keyboard one; can carry out the air sterillization and the sterilization of negative ion to keyboard and other computer peripheral environment when needed; remove airborne bacterium, peculiar smell, dust etc.; create good working environment, the health of the health of protection human body.The utility model adopts single electrode negative direct current high voltage corona discharge, act on airborne hydrone, thereby generation negative ion, avoid when negative ion produces, producing more ozone, avoided the uncomfortable or injury that too much human body caused because of the ozone generating capacity, allowed really relieved, the safe use of user.

Fig. 1 is a shell synoptic diagram of the present utility model;

Fig. 2 is negative high voltage circuit theory diagrams of the present utility model.

Fig. 3 is a structural representation of the present utility model.

Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:

Embodiment

As Fig. 1, shown in Figure 3, keyboard of the present utility model comprises a keyboard case 1, and keyboard is electrically connected on keyboard control circuit.Keyboard case 1 positioned inside has an anion generator 2.Anion generator 2 comprises a negative high voltage circuit 25, a negative high voltage spray point 26.Negative high voltage circuit 25 is electrically connected with keyboard control circuit.As shown in Figure 2, this negative high voltage circuit 25 comprises an oscillatory circuit 22, one transformers 23 and a rectification circuit 24.Oscillatory circuit 22 converts dc low-voltage 21 to AC low-tension; Through transformer 23 AC low-tension is promoted again and be ac high-voltage; After rectification circuit 24 generation-5Kv～-negative high voltage of 10Kv, form high-voltage corona discharge through negative high voltage spray point 26 and discharge negative ions.Offer air intake opening 27 and escape vents 28 on the key panel.

Gas enters anion generator 2 from air intake opening 27, the low-voltage of input is upgraded to negative direct current high voltage by negative high voltage circuit 25, to atmospherical discharges, the hydrone in the ionized air and produce electronegative negative ion discharges from the keyboard case panel through escape vents 28 by anion emission end 26.
