The invention discloses a beaker with a compressed air stirring function. The beaker comprises a beaker body and is characterized in that volumetric scale marks are arranged on the front end face of the beaker body, a liquid pouring mouth is formed in one side of the top end of the beaker body, an end cover is hinged to the upper end of the beaker body, a through hole is formed in the center of the end cover, a small air pump is fixedly connected to the upper end of the end cover, an exhaust pipe vertically extends from the small air pump into the through hole, the upper end of the exhaust pipe is connected to the output end of the small air pump, the lower end of the exhaust pipe is arranged inside the beaker body in a suspended manner, a plurality of air outlets are evenly formed in the panel of the end cover, and a temperature sensing piece is fixedly connected to the inner wall of the beaker body and connected with a display instrument through a transmission wire. By the arrangement, the beaker has the advantage that compressed air can be conveyed to stir a solution during the heating of the beaker to allow the solution to be evenly heated.
