Description

Technical Field

[0001] The utility model relates to a stirrer, in particular to a constant temperature heating magnetic stirrer, belonging to the technical field of magnetic stirrers. Background Art

[0002] A magnetic stirrer is a laboratory instrument used for liquid mixing. It is mainly used to stir or heat and stir low-viscosity liquids or solid-liquid mixtures at the same time. Its basic principle is to use the principle of magnetic field that like charges repel and opposite charges attract, and use the magnetic field to push the magnetic stirrer placed in the container to rotate in a circle, thereby achieving the purpose of stirring the liquid. In conjunction with a heating temperature control system, the sample temperature can be heated and controlled according to specific experimental requirements to maintain the temperature conditions required by the experimental conditions.

[0003] In the prior art, publication number CN217855938U discloses a laboratory magnetic heating stirrer, including a magnetic heating stirrer body and a temperature control tube. The device limits the temperature control tube by cooperating with a limit seat and a side baffle, so that the temperature control tube can move up and down to adapt to different container heights. The heating plate is controlled by the temperature control tube to continuously heat the container from the outside, and the heating temperature is controlled by the temperature control tube. Not only does the continuous heating of the heating plate have a heat preservation effect on the container, but it can also make the container more evenly heated during stirring, further improving the stability of the container during operation; however, the device can only be adjusted in height to adapt to containers of different heights, but cannot adapt to containers of different diameters. At the same time, although the device can keep the container warm on the side, the container mouth still continues to emit heat, which will seriously waste resources in the long run.

[0004] In view of this, this application is hereby filed. Utility Model Content
