Abstract

The utility model discloses a hand warming keyboard which can heat surfaces of keys and keep warm. The hand warming keyboard comprises keys, key support rubber cups, a keyboard upper cover, a power plug, a power on-off switch, a temperature control switch, a heating circuit assembly, a keyboard circuit board, an electronic circuit organic piece, a baseboard and a keyboard lower cover. The keyboard upper cover is a component which is used for connecting or fixing of the keys, the key support rubber cups, the keyboard circuit board, the power plug, the power on-off switch, the temperature control switch, the heating circuit assembly and the like. A power line is used for connecting of the power plug to an external power source and then the power source on-off switch is opened, an electrical heating piece is enabled to be powered on. When temperature of the surface of the keys reaches preset temperature, a heating circuit is opened by the temperature control switch. While the temperature of the surface of the keys falls to below the preset temperature, the heating circuit is closed by the temperature control switch. When the surface of the keys does not need to be heated, the power on-off switch only needs to be switched off and all heating activities are stopped.

The world today, computor-keyboard has entered huge numbers of families along with computer universal, has entered the every field of social all trades and professions, so the warm hand keyboard will have extremely widely market.

[utility model content]

The purpose of this utility model is to provide a kind of and keytop can be heated, warming computer warm hand keyboard.This warm hand keyboard can still make keytop have suitable temperature in the winter of cold, allows the computer operator feel comfortable.

The utility model is achieved through the following technical solutions:

A kind of warm hand keyboard, it comprises: button, button support rubber cup, keyboard top cover, power connection, power on off switch, temp control switch, heating line assembly, keyboard lines plate, electronic circuit biochip, base plate, keyboard lower cover.

Described button comprises key body, electric heating sheets, button lid.Wherein, electric heating sheets passes two small sircle holes on the key body with its two lead-in wires when mounted.Button is the parts that carry out the data input.

Described button supports rubber cup, is the parts of support keys.

Described keyboard top cover is to connect or parts that fixedly button, button support rubber cup, keyboard lines plate, power connection, power on off switch, temp control switch, heating line assembly etc.

Described power connection is an interface unit that is used for connecting external power and power supply is provided to electric heating sheets.

Described power on off switch is a kind of switch that makes the circuit on-off.

Described temp control switch is a kind ofly can according to the variation of temperature, be switched on or switched off the parts of circuit.

Described heating line assembly, it comprises electric wire, wire casing and wiring duct cover, is for the assembly to the electric heating sheets turn-on current.Wherein, electric wire passes the breach on the wire casing, and behind the small sircle hole on the keyboard top cover, is connected with two lead-in wires on the electric heating sheets.

When wire casing and wiring duct cover use thin aluminium to make, the electromagnetic wave that produces in the time of can the shielding wire indirect current.

Described keyboard lines plate is a keyboard device the same with other common keyboard wiring boards.

Described electronic circuit biochip, be one with the same keyboard device of other common keyboard electronic circuit biochips.

Described base plate is a keyboard device the same with other common keyboard base plates.

Described keyboard lower cover, it and keyboard top cover are interlocked, and are keyboard devices the same with other common keyboard lower covers.

Use power lead, connect power connection to external power (such as supply socket), then open power on off switch.The electric current electric wire in crossed beam trunking just makes the electric heating sheets energising like this.After the electric heating sheets energising, just begin the button lid is heated.When the surface of button reached default temperature, temp control switch will disconnect heater circuit, stopped heating.And be reduced to default temperature when following when the surface temperature of button, and temp control switch just can be connected heater circuit again, and then the surface of button will begin again to be heated.Like this, the surface that just can reach button is heated to predetermined temperature, and can keep the purpose of temperature in certain temperature range.

When not needing keytop heated, only need the deenergization on-off switch, can stop all heating activities.

Compare with prior art, the beneficial effects of the utility model are:

One, can heat keytop, and can make keytop in certain temperature range, realize insulation.

Two, this warm hand keyboard is realized the simple to operate of heating and insulation, is easy to each level personnel operation.

Three, this warm hand keyboard structure refining is with low cost.Be applicable to each level family, unit purchase.

Four, when wire casing and wiring duct cover use thin aluminium to make, the electromagnetic wave that produces in the time of can the shielding wire energising.
