Abstract
The utility model discloses a keyboard having a ventilation effect comprising a keyboard shell body and buttons, a fan is arranged on a bottom plate arranged inside the keyboard shell body, a temperature controller is connected with a USB power source E of the keyboard through a switch K, output of the temperature controller is connected with one end of the fan, the other end of the fan is connected with the USB power source E of the keyboard, and wind is blown above the keyboard by the fan through button gaps. According to the keyboard having the ventilation effect, due to the fact that the fan is arranged on the bottom plate arranged inside the keyboard, the fan blows the wind above the keyboard through the button gaps, radiating is performed to the two hands of a user in sweltering seasons, and meanwhile, dust is effectively blown out.
Description
Technical field
This patent relates to a kind of keyboard with ventilation effect.
Background technology
In hot season, people's operation keyboard is easily perspired, and sweat enters the damage that may cause keyboard after the button of keyboard.
Simultaneously, the dust in space is also easily fallen in keyboard by the gap of keyboard, causes the loose contact of button, affects the operation of keyboard.
Existing keyboard can't effectively be lowered the temperature to operation, can not effectively prevent entering of dedusting.
The utility model content
The utility model overcomes above deficiency, and a kind of keyboard with ventilation effect is provided, and can reduce heating and perspiration and the effectively dedusting of the both hands of operation keyboard.
The technical solution of the utility model is as follows:
Keyboard with ventilation effect, comprise keyboard case, button, on the base plate of the inside of keyboard case, blower fan is set, temperature controller is connected with the USB power supply E of keyboard by K switch, the output of temperature controller is connected with an end of blower fan, the other end of blower fan is connected with the USB power supply E of keyboard, the gap of blower fan by button with wind to the keyboard top.
Further, described blower fan is one.
Further, described blower fan is two.
The utility model is by arranging blower fan on the base plate of the inside of keyboard, and then to the keyboard top, can the both hands to the people dispel the heat wind in season of sweltering heat in the gap of blower fan by button.Gap at blower fan by button also can blow out dust when wind is above the keyboard effectively, prevents dust in the deposition in the gap of keyboard, can guarantee that keyboard works normally.
Description of drawings
Accompanying drawing 1 is the circuit theory diagrams of a kind of embodiment of the utility model;
Accompanying drawing 2 is structural drawing of a kind of embodiment of the utility model.
Embodiment
Keyboard with ventilation effect, comprise keyboard case, button, on the base plate of the inside of keyboard case 1, blower fan 2 is set, temperature controller is connected with the USB power supply E of keyboard by K switch, the output of temperature controller is connected with an end of blower fan 2, and the other end of blower fan 2 is connected with the USB power supply E of keyboard.
Turn on-switch K, when temperature was higher, temperature controller output connection signal was connected blower fan 2 with the USB power supply of keyboard, blower fan 2 runnings, the gap that blower fan 2 passes through button with wind above keyboard.
In order to reduce volume, can install in the inside of keyboard, described blower fan 2 should be selected the type of flat pattern.
If adopt larger blower fan, described blower fan 2 can use one.In order to strengthen ventilation effect, described blower fan 2 can use two.
Although this patent is explained with reference to preferred embodiment and accompanying drawing, non-limiting yet above-mentioned explanation should be considered as illustrative, variation and modification that the person's spirit according to the present invention of being familiar with the technique is made all should belong to the protection domain of this patent.
