The invention relates to the technical field of cups, and discloses a drinking cup capable of being cooled rapidly in summer. The drinking cup comprises a cup body, wherein the middle of the side wallof the cup body is provided with a cooling cavity, the inner wall of the bottom end of the cup body is fixedly connected with the side face of a cup bottom plate, and the lower surface of the cup body is fixedly connected with a cup base. The drinking cup capable of being cooled rapidly in summer has the advantages that through the arrangement of the cup body and the cooling cavity, the cup bodyconducts the internal water temperature to the inside of the cooling cavity and the outside of the cup body for cooling, through the arrangement of the cup base, heat conduction plates, cooling fins and heat conduction rods, the heat conduction rods conduct the water temperature in the cup body to the surfaces of the heat conduction plates, the contact area with air is increased through the cooling fins, heat dissipation and cooling are accelerated, a micro motor, a rotating rod and stirring blades are arranged, so that water in the cup body generates vortical motion, thereby increasing the heat dissipation area, through the arrangement of air inlets, a waterproof storage battery, a round rod and rotating fan blades, the flow of the air in the cup body is quickened, and the cooling speed is improved.
