Description

Technical Field

[0001] The utility model relates to the field of laboratory equipment, in particular to a synchronous stirring device supporting multi-degree-of-freedom displacement. Background Art

[0002] Chemical reactions and solution preparation are two crucial steps in routine laboratory operations. However, under traditional technical conditions, the implementation methods of stirring operations in these two processes have significant shortcomings.

[0003] Currently, manual stirring, a common method used in laboratories, is simple to operate, but its effectiveness is limited by physical strength, skill, and experience, making it difficult to achieve precise control. This imprecision can lead to incomplete chemical reactions or uneven solution concentrations, thus affecting the accuracy and reliability of experimental results.

[0004] On the other hand, while electric stirring paddles improve stirring efficiency to a certain extent, their application also has significant limitations. Their limited control capabilities make them unable to meet the demand for multi-degree-of-freedom displacement control of the stirring process. Complex chemical reactions or solution preparation processes often require precise displacement adjustment of the stirrer to achieve optimal stirring. However, a single electric stirring paddle is typically limited to simple rotational motion and cannot achieve this complex displacement control.

[0005] In addition, existing manual mixing schemes require experimenters to spend a lot of time and energy to monitor and adjust the mixing process, which not only increases the workload but may also lead to deviations in experimental results due to interference from human factors.
