Description

Technical Field

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

[0002] Magnetic heating stirrer is a common laboratory equipment, which combines magnetic stirring and heating functions and is widely used in chemistry, biology, pharmaceutical and other fields. It uses magnetic force to establish a rotating magnetic field on the magnetic stirring bar at the bottom of the container, thereby achieving stirring and heating of the liquid in the container. It has the advantages of good stirring effect, uniform heating, safety and convenience.

[0003] In the patent application with authorization publication number CN212188952U, authorization publication date 2020-12-22, and name “Magnetic Heating Stirrer”, the staff can adjust the height of the first fixed plate and the second fixed plate extending out of the fixed tube by respectively threading the two adjusting bolts in different thread grooves, thereby achieving the effect of adjusting the height of the limit plate and the clamping bolt, so that the limit plate and the clamping bolt can fix beakers of different heights, and turn the handwheel to drive the clamping plate and the first silicone rubber pad to move toward the beaker until the first silicone rubber pad and the outer wall of the beaker are pressed against each other;

[0004] In the actual use of the above device, it is necessary to use the adjustment bolt and the threaded groove to fix the beakers at different heights. Since the threaded grooves are arranged at equal intervals, the height adjustment range is relatively limited. In addition, when the material in the beaker is magnetically heated and stirred by the magnetic heating stirrer, the heat continues to accumulate and rise. After the stirring is completed, it is inconvenient to remove the heated beaker.

[0005] Therefore, we propose a magnetic heating stirrer to solve the above problems. Utility Model Content
