Embodiment 1
[0018] Such as figure 1 As shown, the antifreeze keyboard with heating function includes a chassis 1, a circuit board 2 and a keyboard cover 3, a fan 5 is arranged between the chassis 1 and the circuit board 2, and an electric heater is arranged on the fan 5 7. Ventilation holes 4 are provided on the circuit board 2 corresponding to the fan, and a fan switch 6 and an electric heater switch 8 are arranged on the keyboard; the fan 5 and the electric heater 7 are located on the left side of the chassis; the fan switch 6 and the electric heater The switch 8 is located at the side of the chassis 1. During implementation, the ventilation holes on the circuit board 2 avoid places with lines; in order to prevent the performance of the circuit board from being too high after heating, the temperature of the heater should not be too high.
Embodiment 2
[0020] The difference between this embodiment and Embodiment 1 is that the fan switch 6 and the electric heater switch 8 are located on the keyboard cover 3 .

The invention discloses an anti-hand-freezing keyboard with the heating function. The problems that during in winter, heating does not exist indoors in the south, when the keyboard is used, the cold condition frequently occurs, hands are frozen, and are rigid, and working efficiency is low are solved. The anti-hand-freezing keyboard with the heating function comprises a chassis, a circuit board and a keyboard cover plate; a draught fan is arranged between the chassis and the circuit board, an electric heater is arranged on the draught fan, ventilation holes are formed in the portion, corresponding to the draught fan, on the circuit board, and a draught fan switch and an electric heater switch are arranged on the keyboard. According to the anti-hand-freezing keyboard with the heating function, hot air is controlled to blow on the hands, and the hands feel warmth; during summer, only the draught fan is started, the electric heater is not started, cool air is blown, and the hands feel nice and cool, and sweat is blown to be dry; when the anti-hand-freezing keyboard is used, the drying effect and the nice and cool effect are achieved, and the problems that when the keyboard is used inthe hot weather, the hands can sweat, and using is uncomfortable are solved.
Description
technical field [0001] The invention relates to a computer keyboard, in particular to an antifreeze hand keyboard with a heating function. Background technique [0002] Computer keyboards are often used in our life and work. In winter, there is no heating indoors in the south. When using the keyboard, the hands are often cold, which makes the hands stiff and the work efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is: in winter, there is no heating indoors in the south, and the hands are often frozen when using the keyboard, which makes the hands stiff and the work efficiency is low. The present invention provides a heating function to solve the above problems. antifreeze hand keyboard. [0004] The present invention realizes through following technical scheme: [0005] An antifreeze hand keyboard with heating function, including a chassis, a circuit board and a keyboard cover, a fan is arranged between th...
