Below in conjunction with drawings and Examples, the invention will be further described.
A kind of heat collection device of wearable device, comprise heat collection device, thermo-electric generation sheet, booster circuit and voltage stabilizing circuit, heat sensitivity material is all installed at the two ends of heat collection device, two electrode induction end of thermo-electric generation sheet are connected with heat collection device two ends respectively, one end of heat collection device contacts to obtain lasting heat energy with the skin surface of the wearer of wearable device, the other end is away from the skin of wearer, the thermoelectromotive force output LOW voltage that thermo-electric generation sheet is produced by the temperature difference at two ends, low-voltage raises as high voltage by booster circuit, voltage stabilizing circuit burning voltage, thus power for wearable device.
Consult shown in Fig. 1-4, wearable device 10 comprises the temperature difference fever tablet 11 and booster circuit 12 that are connected.
When wearable device 10 is worn on human body, one end of temperature difference fever tablet 11 contacts to obtain lasting heat energy with the skin surface of the wearer of wearable device, and the other end is away from the skin of wearer.In embodiments of the present invention, one end of temperature difference fever tablet 11 is equivalent to face, hot junction, and fit tightly with human body and reclaim heat energy that human body distributes to keep human body temperature, the other end is equivalent to cold junction face, directly contacts to keep ambient temperature with external environment.
When the heat energy of wearer's skin passes through the face, hot junction of temperature difference fever tablet 11, between face, hot junction and cold junction face, produce variations in temperature, according to Seebeck effect also known as thermoelectric effect, in the loop that the face, hot junction of energy recovery module 11 and cold junction face are formed, just produce voltage.Depend primarily on the material behavior at two ends owing to producing the size of voltage, the copper that can produce remarkable thermoelectric effect therefore can be adopted as the two ends of temperature difference fever tablet 11.
The voltage exported by the thermoelectromotive force that the temperature difference at two ends produces in view of temperature difference fever tablet 11 is low-voltage, namely lower than the nominal charging voltage of the rated operational voltage of wearable device 10 or the power supply lower than wearable device 10, therefore booster circuit 12 is needed low-voltage to be raised as high voltage, thus power for wearable device 10, normally run or charging to meet it.
Hold known, the present embodiment can the heat energy that distributes of the automatic recovery human body by temperature difference fever tablet 11, and carry out thermo-electric generation with output LOW voltage, low-voltage being raised by booster circuit is high voltage again, thus output HIGH voltage is for wearable device 10, without the need to wearable device 10 frequent charge, the experience of user can be improved.
In practical application scene, as shown in Figure 1, temperature difference fever tablet 11 can manufacture cuboid structure, can certainly make other arbitrary shapes, it provides face, hot junction and cold junction face by thermo-electric metal sheet 111, to increase the contact area in face, hot junction and wearer's skin.Further, be packaged with semiconductor thermocouple array in thermo-electric metal sheet 111, semiconductor thermocouple array can by intervening sequences spread configuration between face, hot junction and cold junction face, and have good heat conduction to be connected with face, hot junction and cold junction mask.Certainly, also can encapsulate the coupling pad of anodized aluminium in thermo-electric metal sheet 111 to replace semiconductor thermocouple array, or both are combined.
