Abstract
A liquid container capable of self-generating power and showing temperature, comprising: a) a containing body consisting of a housing and an inner wall, a gap being formed between the housing and the inner wall; b) a circuit board positioned within the gap; c) a temperature sensor positioned in the gap for measuring the temperature of the contained liquid, the temperature sensor being electrically connected to the circuit board; d) a temperature indicator disposed in the gap and electrically connected to the circuit board, a displaying surface thereof being positioned on the surface of the housing; and e) a temperature difference power-generating element positioned within the gap and electrically coupled to the circuit board, a thermoelectric effect being created by the hot water filled into the space defined by the inner wall such that a thermal energy can be converted into the electric energy that is stored by an energy-accumulating element for providing the temperature indicator and the related elements with required power.
