Abstract
The invention discloses a keyboard capable of providing warm air. The keyboard comprises a keyboard body. One side edge of the keyboard body is provided with a warm air device which comprises a battery, an electric heating sheet, a fan and a protective cover. The battery is respectively connected with the electric heating sheet and the fan. The electric heating sheet, the fan and the protective cover are arranged in sequence in the direction of the keyboard body. When the keyboard capable of providing the warm air is used, the electric heating sheet is used for heating, and the fan blows the hot air to the keyboard body. In cold days, a user cannot feel cold in the hands after using the keyboard for a long time due to the heating effect of the hot air.
Description
Technical field
The invention discloses a kind of keyboard with warm braw, relate to computer peripheral fittings equipment field.
Background technology
In the time of cold weather, use for a long time computer to need operation keyboard always, it is cold that user's hand can be felt.Because hand belongs to the peripheral circulation of human body, hand cold can allow people think that whole body is all cold, in the time of the cold shake of hand, to the operation of the keyboard difficulty that also becomes, is easy to occur wrong operation.
In prior art, for such technical matters, there is no good solution, is to wear gloves in time, and when cold-proof effect is limited, the dirigibility of impact finger, brings difficulty to operation keyboard too.
Summary of the invention
Technical matters to be solved by this invention is: for the defect of prior art, provide a kind of keyboard with warm braw.
The present invention is for solving the problems of the technologies described above by the following technical solutions:
With a keyboard for warm braw, comprise keyboard body, at a side of keyboard body, be also provided with heater, described heater comprises battery, electric heating piece, fan, protective cover; Battery is connected with electric heating piece, fan respectively, according to the direction towards keyboard body, sets gradually electric heating piece, fan, protective cover.
As present invention further optimization scheme, another side at keyboard body, is symmetrically arranged with another heater.
As present invention further optimization scheme, described battery is charged lithium cells.
As present invention further optimization scheme, described protective cover is latticed, and material is plastics.
As present invention further optimization scheme, described electric heating piece is silicon rubber electric heating piece.
The present invention adopts above technical scheme compared with prior art, has following technique effect: the keyboard with warm braw disclosed in this invention, by electric heating piece, heat in use, and fan drives hot blast to blow to keyboard place.The in the situation that of cold weather, user is due to the heating effect of hot blast, and long-time operation keyboard can not think that hand is cold yet.
Accompanying drawing explanation
Fig. 1 is connection diagram in kind of the present invention,
Wherein: 1. keyboard body, 2. battery, 3. electric heating piece, 4. fan, 5. protective cover.
Fig. 2 is circuit connection diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
As shown in Figure 1, a kind of keyboard with warm braw, comprises keyboard body to connection diagram in kind of the present invention, at a side of keyboard body, is also provided with heater, and described heater comprises battery, electric heating piece, fan, protective cover; Battery is connected with electric heating piece, fan respectively, according to the direction towards keyboard body, sets gradually electric heating piece, fan, protective cover.
As present invention further optimization scheme, another side at keyboard body, is symmetrically arranged with another heater.The heater of an independent side can play the due warming effect of heating, and symmetrically arranged heater can better form the convection current of hot-air, strengthens intensification effect.
As present invention further optimization scheme, described battery is charged lithium cells.Also can use the design of external power supply, comparatively speaking, use charged lithium cells to avoid the winding of power lead, use more convenient.
As present invention further optimization scheme, described protective cover is latticed, and material is plastics.Protective cover can be avoided the fan finger of injuring, and uses that plastic material is cheap, Portable durable.
As present invention further optimization scheme, described electric heating piece is silicon rubber electric heating piece.Silicon rubber electric heating piece is exactly a kind of soft flexible film-form electrothermal device.It is that pool shape, thread metallic heating body are distributed between the glass fabric that is coated with high-temperature-resisting silicon rubber, through hot press moulding, are formed.Its body is thin, and thick 0.8 ~ 1.5MM, light weight, general conventionally, 1.3 ~ 1.9 kilograms every square.Heating power is rapid, temperature rise is fast, has that heating face is large, even, weather-proof, the corrosion resistant of generating heat, environmental protection, the characteristic that fire-retardant, easy for installation, the life-span is long, dielectric strength is high.
Circuit connection diagram of the present invention as shown in Figure 2, battery is given respectively electric heating piece and fan power supply, the hot-air that electric heating piece heated is driven and to be blowed to keyboard top by fan, improves near air themperature keyboard, allows user's snugness more in operation keyboard.
By reference to the accompanying drawings embodiments of the present invention are explained in detail above, but the present invention is not limited to above-mentioned embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from aim of the present invention, makes a variety of changes.
