Sub- ontology, stirrer ontology are easier to drive solution motion, improve stirring efficiency.
The utility model is further arranged to：The magnetic stirrer further includes being fixedly connected on the stirrer ontology two
The central axis of the stirring rod at end, stirring rod is parallel with the central axis of stirrer ontology, and stirring rod is thinner than stirrer ontology.
Through the above technical solutions, driving stirring rod rotation when stirrer ontology rotates, stirring rod can drive to be located at and stir
The solution motion for mixing sub- ontology end positions improves the movement velocity of solution, improves stirring efficiency.
The utility model is further arranged to：Viscid bar is vertically fixedly connected with above the stirring rod.
Through the above technical solutions, when viscid bar increases stirring rod rotation and the squish area of solution, can increase pair
The thrust of solution, it is easier to drive solution to rotate, improve stirring efficiency.
The utility model is further arranged to：The viscid bar is distributed around the central axis helical array of the stirring rod.
Through the above technical solutions, more viscid bars are uniformly distributed on the circumference of stirring rod while along the centers of stirring rod
Axis is uniformly distributed, and stirrer ontology is after the center axis thereof certain angle of itself, and stress compares balance to stirring rod everywhere,
Stirring rod remains to keep the transmission of relatively balance with solution, this body running of stirrer is more steady.
The utility model is further arranged to：The end face of the viscid bar far from the stirring rod is arc surfaced.
Through the above technical solutions, solution is easier to slide along cambered surface, solution is not easily formed near viscid bar
Larger cavity can improve the contact probability of viscid bar and solution, improve stirring efficiency.
The utility model is further arranged to：The both ends of the surface of the stirrer ontology are arc surfaced.
Through the above technical solutions, solution is easier to slide into groove along cambered surface, groove is easier to drive solution motion.
In conclusion the utility model has the advantages that：
1, solution can enter in the groove in stirrer ontology both ends of the surface, when stirrer ontology rotates, the side of groove
Solution motion, solution can be driven to be not easy directly around stirrer ontology, therefore, stirrer ontology is easier to drive solution fortune
It is dynamic, improve stirring efficiency；
2, stirring rod can be stirred the solution at stirrer ontology both ends, drive the molten of stirrer ontology end positions
Liquid movement improves stirring efficiency；
3, viscid bar increase stirring rod rotation when and solution squish area, the thrust to solution can be increased, more held
Solution rotation is easily driven, stirring efficiency is improved.
