The present invention is achieved through the following technical solutions: a kind of vibrating motor, comprise housing, rotate in described housing and be provided with output shaft, described housing sidewall is provided with two coils staggered relatively, AC power is passed in described coil, described output shaft is fixedly installed the armature component responding described coil, described armature responds the change in magnetic field in described coil thus makes described output shaft do the rotation of special angle along axle center, in described housing, be positioned at output shaft pendulum angle be outside equipped with trigger switch, when output shaft pendulum angle is abnormal, armature on described output shaft contacts with this trigger switch.
In technique scheme, described special angle is between 2 to 7 degree, and described anomalous swing angle is more than 9 degree.
In technique scheme, also comprise an elasticity inserted sheet, groove is provided with bottom described output shaft, the slot inserted for described elasticity inserted sheet is provided with at this bottom land end, described elasticity inserted sheet one end is provided with the driving mechanism promoting described elasticity inserted sheet, described driving mechanism is electrically connected with described driving switch and this driving mechanism is fixed on described housing, and when driving switch changes described AC power output frequency, elasticity inserted sheet described in described driving mechanisms control inserts or departs from described slot.
In technique scheme, described housing comprises upper end cover and bottom end cover, is provided with the bearing for supporting described output shaft in described upper end cover and bottom end cover.
The present invention has following beneficial effect: the present invention, when care implement is in abnormal angle swinging, detects above-mentioned exception by trigger switch, to remind user to maintain care implement in time.

Fig. 1 is structural representation of the present invention.
Fig. 2 is the cross-sectional schematic along A-A line in Fig. 1.
Fig. 3 is the slot arranged bottom output shaft.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail: see Fig. 1 to Fig. 2, a kind of vibrating motor, comprise housing 1, described housing 1 comprises upper end cover 10 and bottom end cover 11, rotate in described housing 1 and be provided with output shaft 2, the bearing 8 for supporting described output shaft 2 is provided with in described upper end cover 10 and bottom end cover 11, described housing 1 sidewall is provided with two coils 4 staggered relatively, AC power is passed into make to be formed the magnetic field of alternation between coil in described coil 4, also comprise the driving switch 5 for controlling described ac power frequency, described output shaft 2 is fixedly installed the armature component 3 responding described coil 4.There is gap between described armature component 3 and described coil 4, with the reciprocating motion making output shaft 2 can carry out special angle in this interstice coverage, above-mentioned special angle is between 2 degree to 7 degree.In described housing 1, be positioned at output shaft 2 pendulum angle be outside equipped with trigger switch 9, described trigger switch 9 is connected in inner walls by a support chip 9a, this support chip 9a has elasticity, when output shaft 2 pendulum angle is abnormal, the armature component 3 on described output shaft 2 contacts with this trigger switch 9.Described anomalous swing angle is more than 9 degree.Namely, when the vibrating motor of appliance for personal care is in abnormal angle swinging, trigger switch 9 can detect above-mentioned exception, thus reminds user to carry out care and maintenance (by trigger switch 9 is connected alarm unit or signal etc. to realize prompting function) to care implement in time.
Also comprise an elasticity inserted sheet 6, groove 20 is provided with bottom described output shaft 2, the slot 21 inserted for described elasticity inserted sheet 6 is provided with in this groove 20 bottom, see Fig. 3, described slot 21 is provided with three, be provided with three elasticity inserted sheets 6 coordinated with described slot 21 accordingly, described elasticity inserted sheet 6 one end is provided with this driving mechanism of driving mechanism 7(promoting described elasticity inserted sheet 6 can select small cylinder or hydraulic cylinder etc.), described driving mechanism 7 is electrically connected with described driving switch 5 and this driving mechanism 7 is fixed on described housing 1, when driving switch 5 changes described AC power output frequency, described driving mechanism 7 controls described elasticity inserted sheet 6 and inserts or depart from described slot 21.When driving switch 5 changes described AC power output frequency, described driving mechanism 7 controls described elasticity inserted sheet 6 and inserts or depart from described groove slotting 21.Concrete, the output frequency that the natural frequency of output shaft 2 can be set to the less gear with coil is consistent, when appliance for personal care complete machine output frequency is positioned at this gear, because output shaft 2 natural frequency and coil 4 natural frequency are consistent, and now elasticity inserted sheet does not insert the groove being positioned at and arranging bottom output shaft 2, when this less gear, coil output frequency can ensure to reach consistent with the frequency of vibrating motor output shaft, thus reach resonance, make the vibration of vibrating motor be passed to care implement brush position fully, while use driving switch 5 is by the larger gear of the output frequency of coil modulation, driving mechanism 7 receives the signal of above-mentioned driving switch 5 change, thus drive elasticity inserted sheet 6 to move to slot 21 direction, and enter in the slot 21 that is arranged on and offers bottom output shaft 2, make output shaft 2 when special angle rotates, by elasticity inserted sheet resiliency supported, be equivalent to the natural frequency being added output shaft by elasticity inserted sheet, above-mentioned setting ensure that when coil switches the output frequency of different gear, by to be arranged at respective numbers reed in slot 21 that output shaft 2 is offered thus to ensure when different gear, coil output frequency remains consistent with output shaft natural frequency all the time.
That more than enumerates is only specific embodiments of the invention, obviously, the invention is not restricted to above embodiment.All distortion that those of ordinary skill in the art can directly derive from content disclosed by the invention or associate, all should belong to protection scope of the present invention.
