An automatic hot water stirring cup comprises a cup body and a liner, the upper portion of the liner is connected with the cup body, a containing cavity is formed among the liner, the side wall of thecup body and the bottom of the cup body, one surface of a power generating piece is connected on the outer surface of the bottom of the liner, the other surface of the power generating piece is connected on the upper surface of a metal cup bottom cover, a cup bottom is connected on the lower portion of the cup bottom cover, the cup bottom and the cup bottom cover form a heat-conducting medium containing chamber, a heat-conducting medium is stored into the heat-conducting medium containing chamber, a motor is arranged in the cup bottom cover, the power generating piece is connected with the motor through a PCB (printed circuit board), a shaft of the motor is connected with a magnet, a magnet is arranged at the position corresponding to the inner surface of the bottom of the liner, and themotor drives the magnets to rotate to generate magnetic force, so that water is stirred. The power generating piece of the cup generates power by the aid of the temperature difference of hot water todrive the motor to rotate, the magnet is connected on the shaft of the motor, the motor drives the magnets to rotate to generate the magnetic force, water in the cup is stirred, stirring and cooling are achieved, the integrity of the liner is not broken, and cleaning is facilitated.
