Embodiment
As shown in Fig. 1 ~ Fig. 4, a kind of Miniature reciprocating wig-wag that present pre-ferred embodiments proposes, it is made up of stator, rotor and end cap group group.Stator specifically comprises: Single port shrink and the open cylindric casing 1 in another port, riveted at the clutch shaft bearing 2 of this casing 1 retract port inner cavity top, at least two pairs of pole piece shape magnet steel 3 be located in casing 1 inner chamber.In the present embodiment, magnet steel 3 is two of Nd-Fe-B magnet steel to pole magnet steel, is located in casing 1 with adopting spacing frock, polarity.Multipair pole piece shape magnet steel 3 can also be set as required.
Rotor specifically comprises: rotating shaft 6, the iron core 8 being pressed into the trough of belt in this rotating shaft 6, the winding 16 be wrapped in this iron core 8 groove, connect the piezo-resistance 10 being intended to surge current suppression of this winding 16, connects the conducting strip 11 that winding 16 plays the role of changing.Also comprise the copper ring retainer plate 7 two force fit rotating shafts 6 being also pressed in respectively iron core 8 liang of end surfaces, to improve the peel force of rotating shaft 6.Be enclosed within the insulation dististyle 5 of copper ring retainer plate 7 external diameter, by iron core 8, copper ring retainer plate 7, axial a pair packing ring 4 be defined in described rotating shaft 6 of insulation dististyle 5, piezo-resistance 10 and conducting strip 11.In the present embodiment, described iron core 8 adopts two channel cores, and the corresponding winding 16 be wrapped in the groove of this iron core is also two groups.
End cap group comprises: riveted is connected to the brush 12 of conducting strip 11 external diameter in rotor and lower end press-in end cap 13 to the end cap 13 with limited post of casing 1 lower open port, the second bearing 17 be located in end cap 13, top; The two ends of described rotating shaft 6 are stretch out described casing 1 respectively by first, second bearing described, and the spindle nose being stretched out the rotating shaft 6 of below casing by the second bearing 17 is provided with the spacing catch 14 of die cast metal, and effect is restrict rotor full swing amplitude.In the present embodiment, conducting strip 11 gland is in rotating shaft 6, and its upper end is against the copper ring retainer plate 7 of iron core 8 lower end, and piezo-resistance 10 is socketed on again the external diameter of conducting strip 11.Packing ring 4 is the packing ring in a pair loading rotating shaft 6, one of them packing ring 4 is against the insulation dististyle 5 of iron core 8 upper end, another packing ring 4 is against the lower end of the conducting strip 11 of iron core 8 bottom, then iron core 8, copper ring retainer plate 7, insulation dististyle 5, piezo-resistance 10 and conducting strip 11 are axially defined in rotating shaft 6 by a pair packing ring 4, and can in order to the gap of regulating shaft system part.First, second bearing adopts oiliness bearing.The spindle nose of the rotating shaft 6 of being stretched out by casing 1 top by clutch shaft bearing 2 is used as output shaft, and it also connecting one provides the axle sleeve 15 exporting and connect.
As shown in Figure 5, Figure 6, the operation principle of present pre-ferred embodiments, when giving the positive and negative alternate electric current of motor, the N pole of the magnet steel 3 that the magnetic field that rotor 20 produces alternation will be fixed, S pole attract and reciprocating rotation successively, thus form the reciprocally swinging of fixed frequency.As shown in Figure 5, when giving the energising of motor forward, rotor 20 forms a magnetic field, under the magnetic field interaction that the fixing magnet steel 3 with stator is formed, and the angle that rotor 20 clockwise oscillation one is fixed.As shown in Figure 6, when giving motor and being oppositely energized, rotor 20 define one with magnetic field just contrary shown in Fig. 3, under the magnetic field interaction that the fixing magnet steel 3 with stator is formed, rotor 20 has back swung a fixed angle counterclockwise.When giving the forward and reverse alternate energisation of motor fixed frequency, rotor 20 will do a reciprocal swing back and forth according to this frequency.Traditional iron core DC vibration motor, its rotor is rotary motion, vibration is obtained by increasing an eccentric block in rotating shaft, its shortcoming is: need commutator to carry out mechanical commutation (affecting the life-span), bearing is existed to the pressure (affecting the life-span) of the radial direction suitable with eccentric block centrifugal force, shuttle swing (having influence on the cleaning effect of toothbrush) can not be provided.Comparing lower vibration frequency of the present invention stablizes controlled, and the life-span is long, and reliability is high, can be widely used on the products such as electric toothbrush, massager, cleaning supplies.
