With reference to Fig. 5 a to Fig. 5 c：
In mini sprinkler device during the quantity difference of bar shaped magnetic pole 8, the magnetic field intensity around magnetic stir bar 14 is change.
The magnetic field around magnetic stir bar is analyzed by simulation software, the domain of air-shed and solution is first drawn, secondly utilizes
Difference set in brewer computing removes magnet and air-shed intersection.Grid is carried out respectively to rotating part and stationary part to cut open
Point, after completing mesh generation, the direction of magnetization is set to each magnet respectively, the intensity of magnetization of magnet is arranged to 900KA/m.Carry out
Stable state and Transient, the figure that stirrer Moment changes over time when Distribution of Magnetic Field and magnetic pole when obtaining static rotate
Picture.
(1) under quiescent conditions：When magnetic pole logarithm is three, the magnetic field around magnetic stir bar is most strong and more uniform.When
For two pairs of magnetic poles when, the magnetic field intensity of magnetic stir bar near zone is relatively low.When magnetic pole logarithm be four when, due between magnet away from
From closely causing magnetic field mutually to weaken very much, the magnetic field around magnetic stir bar on the contrary than three pairs of magnetic poles when come it is weak.
(2) when magnetic pole rotates, electromagnetism rotating is multiplied by magnetic pole logarithm equal to mechanical separator speed.When mechanical separator speed keeps constant,
Due to the increase of magnetic pole logarithm, the changes of magnetic field speed increase of stirrer surrounding space, therefore in same time, crest occurs
Number be scaling up, field frequency accelerate.The size that magnetic pole logarithm p=2/3/4 corresponds to moment of torsion average value respectively is
0.0152、0.0193、0.0188.As can be seen that increase during moment of torsion average value opposing polarities logarithm p=2 during magnetic pole logarithm p=3
Add it is larger, but magnetic pole logarithm p=4 moment of torsion average value relative to magnetic pole logarithm p=3 value slightly reduce.Magnetic pole logarithm p=3
When, moment of torsion average value is maximum.
As can be seen here, the result of magnetostatic field simulation result and Transient matches, moment of torsion suffered by magnetic stir bar
Size is neither proportional with magnetic pole logarithm, also not inversely.So in mini sprinkler device, outside magnetic stir bar
When face sets three pairs of strong magnetic bar magnets, device operating efficiency highest.
In conjunction with shown in Fig. 6 a to Fig. 6 c：When bar magnet 8 arrives the distance difference of rotation axis in the mini sprinkler device,
The rotates effe of magnetic stir bar 14 is different.Therefore, magnetic force during distribution of static magnetic field and magnet movement during to different distance
Torque suffered by stirrer carries out finite element simulation.In view of the limitation of the diameter of internal drain pipe, choose respectively away from
Emulated from 15mm, 20mm, 25mm.As shown in fig. 6, under three kinds of pole pitch, in the distribution map of magnetostatic field, magnet is from center
Axle is nearer, and the spatial color near magnetic stir bar is more shallow, and the magnetic field intensity near magnetic stir bar is bigger.Under Transient
15mm, 20mm, 25mm are 0.0193,0.0164,0.0158 apart from average torque size corresponding to lower difference, it can be seen that wink
The result of state emulation matches with magnetostatic field simulation result, and in existing distance range, magnet is nearer from magnetic stir bar, is produced
Raw average torque is bigger.It is so magnet is the most suitable from 15mm is set to a distance from central shaft.
As shown in fig. 7, using above-mentioned there is stirring and the course of work of the mini sprinkler of heating function to be：
During work, mini sprinkler of the present invention is arranged on high speed and precision X-Y two-dimension moving platforms, and and high voltage power supply
