Description
Technical field
The utility model relates to a kind of counter, particularly a kind ofly utilizes thermoelectric cell as power supply to support the electronic calculator of its normal operation.
Background technology
Present stage, most of ordinary electronic counter was merely using thin-film solar cells or common button cell as power supply, but use above-mentioned two kinds of batteries to have some limitations as its scope of application of electronic calculator of power supply, if when in illumination, insufficient or button cell electricity is not enough, LCDs display effect is not good.The utility model efficiently solves the problems referred to above.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of counter with thermoelectric cell, its electric energy utilizing thermoelectric cell to produce is used counter can normally be worked, and reach energy-conservation effect.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is, a kind of counter with thermoelectric cell, comprise body, the side, front of body is provided with display screen and keyboard, the side, the back side of body is provided with backboard, and be provided with circuit board in the accommodation space of display screen, keyboard and backboard composition, display screen and keyboard are all electrically connected with circuit board; The side of backboard display screen dorsad is also provided with for collecting heat energy and being converted to the thermoelectric cell of electric energy, circuit board is provided with thermoelectric cell circuit, power-supplying circuit and computer circuits, the input end of this thermoelectric cell circuit is connected to the output terminal of described thermoelectric cell, the input and output of thermoelectric cell circuit are terminated at the input/output terminal of power-supplying circuit, and the output terminal of power-supplying circuit is connected to computer circuits.Existing battery by the program, is replaced with thermoelectric cell and powers directly to counter by the utility model, and its thermal power transfer that thermoelectric cell can be produced be electric energy, and powers, to save the energy consumption of counter for computer circuits.
Further, described thermoelectric cell is semiconductor temperature difference battery or Metal Temperature difference battery.
As a feasible scheme, further, the thermo-electric generation element that described thermoelectric cell includes the hot junction layer as hot junction, the cold junction layer as cold junction and is folded between this hot junction layer and cold junction layer, hot junction layer be near human body side by thermosphere, cold junction layer is for deviating from the heat dissipating layer of human body side, described hot junction laminating invests on the surface of the backboard side of display screen dorsad, and cold junction laminating invests backboard towards on the surface of the side of display screen.Like this, hand-held change counter time, the difference of human body temperature and counter temperature is converted to electric energy by thermoelectric cell, and by transferring to power-supplying circuit after thermoelectric cell circuit rectifies voltage stabilizing process, the voltage that power-supplying circuit controls thermoelectric cell circuit is that computer circuits is powered.
The utility model adopts such scheme, thermoelectric cell is placed in the bottom of counter, under the condition that staff grips, utilizes thermoelectric cell that the difference of body temperature and counter temperature is converted into electric energy, thus provide required electric energy for counter, and it is made to reach the effect of normal work.By such scheme, make the effect that counter reaches energy-conservation; Meanwhile, the utility model structure is simple, is easy to industrialization and produces, have good practicality.
Accompanying drawing explanation

Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
As a concrete example, see Fig. 1-Fig. 3, a kind of counter with thermoelectric cell of the present utility model, comprise body 1, the side, front of body 1 is provided with display screen 2 and keyboard 3, the side, the back side of body 1 is provided with backboard 4, and be provided with circuit board in the accommodation space of display screen 2, keyboard 3 and backboard 4 composition, display screen 2 and keyboard 3 are all electrically connected with circuit board; The side of backboard 4 display screen 2 dorsad is also provided with for collecting heat energy and being converted to the thermoelectric cell 5 of electric energy.
See Fig. 4, circuit board is provided with thermoelectric cell circuit, power-supplying circuit and computer circuits, the input end of this thermoelectric cell circuit is connected to the output terminal of described thermoelectric cell, the input and output of thermoelectric cell circuit are terminated at the input/output terminal of power-supplying circuit, and the output terminal of power-supplying circuit is connected to computer circuits.Existing battery by the program, is replaced with thermoelectric cell and powers directly to counter by the utility model, and its thermal power transfer that thermoelectric cell can be produced be electric energy, and powers, to save the energy consumption of counter for computer circuits.
Wherein, thermoelectric cell can by semiconductor temperature difference battery or Metal Temperature difference battery.In the present embodiment, the thermo-electric generation element that thermoelectric cell specifically comprises the hot junction layer as hot junction, the cold junction layer as cold junction and is folded between this hot junction layer and cold junction layer, hot junction layer be near human body side by thermosphere, cold junction layer is for deviating from the heat dissipating layer of human body side, hot junction laminating invests on the surface of the backboard side of display screen dorsad, and cold junction laminating invests backboard towards on the surface of the side of display screen.Like this, hand-held change counter time, the difference of human body temperature and counter temperature is converted to electric energy by thermoelectric cell, and by transferring to power-supplying circuit after thermoelectric cell circuit rectifies voltage stabilizing process, the voltage that power-supplying circuit controls thermoelectric cell circuit is that computer circuits is powered.
