Wherein, the hot end 210 of thermoelectric generation component 200 refers to the thermoelectric generation component 200 and is close to the one end that the temperature is relatively higher, correspondingly, the cold end 220 of thermoelectric generation component 200 refers to the thermoelectric generation component 200 and is close to the one end that the temperature is relatively lower, and there is the temperature difference at the hot cold both ends of thermoelectric generation component 200, can produce the potential difference in thermoelectric generation component 200 to form the electric current.
