The mode that axis 50 moves connects, which is driven to carry out eccentric rotary by motor 30, since eccentric shaft 50 is in circumference side
Upward position constantly changes, i.e., the position of centre of gravity of eccentric shaft 50 constantly changes in a circumferential direction so that eccentric
Axis 50 drives the resultant motion (or vibration) that movable part 20 and brush head 21 twist with flexural deformation, the above-mentioned movement of brush head 21
Just it is fitted with the action manually brushed teeth, electric tooth brushing can be realized from energy.Know by theoretical calculation and experimental verification, it is eccentric
If the radial position of the circular motion of axis 50 and axial location can change, the vibration of eccentric shaft 50 can be changed
Frequency and amplitude, so as to meet the action for the brush head 21 that different vibrations require.To realize the purpose, in the prior art in eccentric shaft
One helical spring is set between 50 and motor 30, so that realizing flexible connection between eccentric shaft 50 and motor 30, works as motor
During 30 raising rotating speed, under the influence of centrifugal force, since helical spring diametrically only has less constraint to eccentric shaft 50, partially
Mandrel 50 can realize the change of radial position, so that vibration frequency and amplitude are changed, but helical spring is for eccentric shaft 50
The change of axial location do not play positive effect, or even play negative consequence, that is to say, that turn when motor 30 improves
When fast, the coefficient of elasticity of helical spring becomes larger, and helical spring becomes not soft as before, so as to prevent the axis of eccentric shaft 50

Can change to position, it is often more important that, when motor 30 drive steel wire 40 rotate when, due to steel wire 40 bending section it is each
Particle cannot be similar to the above-mentioned tangential power driving (reality of steel wire 40 in same plane, motor 30 to be applied to steel wire 40
On, the structure for applying circumferential force is simultaneously not present in the bending section of steel wire 40), but steel wire 40 is driven by motor 30, steel wire 40 is certainly
Body is by realizing the transmission of torque against torsion, so that the bending drag of steel wire 40 in the axial direction will not change,
