Provided is a stirring cup driven by
heat energy. The stirring cup comprises a cup body which is internally provided with a power generation device, the power generation device is connected with a stirring device, and the power generation device comprises a
temperature difference power generation piece. In the power generation device, the
temperature difference power generation piece is located in the side wall of the cup body, an inner layer
heat conducting plate and an outer layer
heat conducting plate are arranged on the inner side and the outer side of the
temperature difference power generation piece respectively, and heat insulating
layers are arranged at the upper end and the lower end of the temperature difference power generation piece respectively. In the stirring device, a driving device drives a permanent
magnet blade to rotate through magnetic force. According to the stirring cup driven by the
heat energy, the energy-saving effect is achieved by utilizing the temperature difference power generation piece to generate
electricity to drive the stirring device to rotate. In the optimal scheme, the temperature difference power generation piece is arranged on the side wall of the cup body, the heat exchange area is increased, and the
generating capacity is increased. The mode that the permanent
magnet blade is driven by the magnetic force to rotate is adopted, no fixed connection exists between the permanent
magnet blade and the cup body, the inner wall of the cup body is complete, no transmission shaft exists, and no transmission shaft hole exists.
