Constant-temperature magnetic stirrer

The utility model discloses a constant-temperature magnetic stirrer which comprises a device body, a heating groove is formed in the top of the device body, a heating pot is assembled in the heating groove, a heating assembly and a magnetic stirring mechanism are assembled in the position, located at the bottom of the heating groove, of an inner cavity of the device body, and a clamping frame is fixedly assembled on the top of the device body. And a temperature detection sensor is clamped in the clamping frame. The driving mechanism assembled in the device main body can drive the stirring assembly to rotate in the process of heating water in the heating pot, so that the water in the heating pot can flow and be uniformly mixed in the heating process, and the heating efficiency of the water is improved; and meanwhile, the temperature detected by the temperature detection sensor is the overall temperature of the fully and uniformly mixed water instead of the water temperature at a fixed position in the heating p
