The utility model is further arranged to, and rechargeable battery, the thermo-electric generation sheet are provided with the electronic thermometer
Output end be connected with rechargeable battery, the pole of counnter attack two is in series between the output end and rechargeable battery of the thermo-electric generation sheet
Pipe.
In said structure, due to thermo-electric generation sheet generating capacity depend on cabinet in the temperature difference outside cabinet, therefore
In Various Seasonal, it frequently can lead to the temperature difference and significantly change be present, as winter cabinet external temperature is low, internal temperature is high, temperature difference hair
Electric piece can be well utilize thermo-electric generation, and to summer temperature raise, cabinet internal-external temperature difference can be caused to diminish so that the temperature difference send out
Electric piece generating capacity reduces, it is therefore desirable to sets rechargeable battery to keep in electricity, in case of need, counnter attack diode can be effective
Avoid when thermo-electric generation sheet does not work, the electric energy reverse flow in rechargeable battery to thermo-electric generation sheet.
The utility model is further arranged to, if the thermo-electric generation sheet is dry plate, and after being one another in series with electron temperature
Meter electrically connects or electrically connects or be one another in series with electronic thermometer after being connected in parallel to each other in parallel electric with electronic thermometer again after group
Connection.
In said structure, due to monolithic thermo-electric generation sheet, its caused Current Voltage is smaller, if therefore can be by the dry plate temperature difference
Power generation sheet mode in parallel after carrying out in parallel, series connection or connecting is combined, and it is produced enough electric currents and is come with voltage for electricity
Sub- thermometer provides electric power and charged for rechargeable battery.
The beneficial effects of the utility model：Generated electricity by setting electronic thermometer on cabinet, and using thermo-electric generation sheet,
First can reduce electric energy loss, and second can avoid the power taking out of cabinet, prevent potential safety hazard, while using rechargeable battery to temperature
The electric energy that poor power generation sheet is sent is stored, with solve cabinet internal-external temperature difference it is smaller when thermo-electric generation sheet do not generate electricity and cause electronics
The problem of thermometer can not work.
