To N pole magnet and S pole magnet, the plane of symmetry between described N pole magnet and S pole magnet and described silicon steel body
Adjutage two sides between the plane of symmetry coplanar.This structure designs, after coil block is energized, according to the right side
Hand screw rule so that two coil blocks produce two identical magnetic poles respectively with core assemblies sides adjacent,
And interacted with the N pole magnet being distributed on annular magnetite and S pole magnet by the silicon steel body of both sides,
There is a natural attraction between the sexes, makes drive shaft generation positive deflection, when the coil block sense of current under the effect that the same sex is repelled each other
During change, the magnetic pole of core assemblies changes the most therewith, and then orders about drive shaft and reversely deflect, by electric current
High frequency changes so that drive shaft comes and goes and rotates, and then produces vibration, to reach the tooth being connected with drive shaft
It is brushed with the effect of effect cleaning tooth.
