The invention relates to an intelligent water cup provided with a control chip. The intelligent water cup comprises a cup cover and a cup body, wherein a flexible LED display screen and porous rubberare arranged between the upper part of the inner wall of a case of the cup body and an inner liner; the lower bottom surface of the inner liner is connected with a hot end of a thermoelectric power generation device; the cold end of the thermoelectric power generation device is connected with a heat radiator; the heat radiator is welded onto an opening container to form a sealed heat storage medium container; phase change heat storage media are arranged in the heat storage medium container; a PCB is arranged in a space formed at the bottom of the heat storage medium container and the bottom surface of the case of the water cup; the control chip is arranged on the PCB; and the PCB is connected with the thermoelectric power generation device and the flexible LED display screen through a conducting wire to from a circuit. The intelligent water cup has the advantages that the structure is simple; the carrying is convenient; heat energy of hot water in the cup can be converted into electricenergy supplied for a circuit to be used; and a user can control contents displayed on the flexible LED display screen through the wireless connection between mobile phone app or WeChat applet and the control chip arranged on the PCB.
