Description

Technical Field

[0001] The utility model relates to the technical field of chemical experiments, in particular to a magnetic stirrer with a noise reduction function. Background Art

[0002] Magnetic stirrers are commonly used in chemical laboratories to heat and stir solutions. Magnetic stirrers use the principle of like charges repel and opposite charges attract in the magnetic field to drive the magnetic stirrer placed in the container to move in a circular motion, thereby achieving the purpose of stirring the liquid. The stirring effect is good and it is easy to use.

[0003] The existing Chinese public patent (authorization announcement number: CN211216455U) mentions a magnetic stirrer, including a stirrer body, an operation panel with a display screen is arranged outside the shell of the stirrer body, a brushed motor controlled by a controller is arranged inside the shell, the motor shaft of the brushed motor extends upward out of the shell, the motor shaft located in the shell is passed through a radial magnetized magnetic ring, a Hall sensor for detecting the radial magnetized magnetic ring signal is arranged in the shell, and the signal output end of the Hall sensor is connected to the signal input end of the controller. The utility model has the advantage of overcoming the technical problem of the error in the stirring speed of the traditional magnetic stirrer and realizing the precise control of the stirring speed. Specifically, during the rotation of the motor shaft, the Hall sensor detects the radial magnetized magnetic ring signal and transmits the signal to the controller, and the controller transmits the processed data to the display screen of the operation panel, and displays the stirring speed through the display screen.

[0004] When an existing magnetic stirrer stirs a solution inside a container, the liquid inside the container is in a swirling shape, causing the container to be subjected to force. When the solution needs to be stirred at high speed, the liquid is subjected to greater force, resulting in an excessively fast swirling speed, causing the container to be subjected to greater force and vibration. This not only causes loud noise but also causes positional displacement, affecting stirring. Therefore, we have proposed a magnetic stirrer with a noise reduction function that is convenient for stabilizing the position of the container to solve the above problems. Utility Model Content
