Degree is abnormal, above-mentioned abnormal angle user using when may be not easy to be discovered, but for care implement, exist for a long time
Easily vibrating motor is caused damage during above-mentioned abnormal angular turn/swing so that its service life is reduced.
The content of the invention
For the deficiencies in the prior art, the invention provides a kind of vibrating motor, in care implement in abnormal
During angle swinging, above-mentioned exception is checked by trigger switch, to remind user maintenance guarantor to be carried out to care implement in time
Support.
The present invention is achieved through the following technical solutions：A kind of vibrating motor, including housing, rotate in the housing
Output shaft is provided with, and the housing sidewall is provided with two coils staggered relatively, alternating current power supply is passed through in the coil,
The armature component for responding the coil is fixedly installed on the output shaft, the armature responds the change in magnetic field in the coil
Change so that the output shaft does the rotation of special angle along axle center, be located at outside output shaft pendulum angle in the housing
Trigger switch is provided with, when output shaft pendulum angle is abnormal, the armature on the output shaft is contacted with the trigger switch.
In above-mentioned technical proposal, between 2 to 7 degree, the anomalous swing angle is more than 9 degree for the special angle.
In above-mentioned technical proposal, also including an elastic inserted sheet, the output shaft bottom is provided with groove, sets at the bottom land end
The slot for the elastic inserted sheet insertion is equipped with, described elastic inserted sheet one end is provided with the driving machine for promoting the elastic inserted sheet
Structure, the drive mechanism is electrically connected with the driving switch and the drive mechanism is fixed on the housing, works as driving switch
When changing the alternating current power supply output frequency, described in the driving mechanisms control, elastic inserted sheet is inserted or departs from the slot.
In above-mentioned technical proposal, the housing includes upper end cover and bottom end cover, arranges in the upper end cover and bottom end cover
Have for supporting the bearing of the output shaft.
The present invention has the advantages that：The present invention is opened by triggering when care implement is in abnormal angle swinging
The above-mentioned exception of detection is closed, to remind user to maintain care implement in time.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the cross-sectional schematic in Fig. 1 along line A-A.
Fig. 3 is the slot that output shaft bottom is arranged.
Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings：It is referring to Fig. 1 to Fig. 2, a kind of
Vibrating motor, including housing 1, the housing 1 include upper end cover 10 and bottom end cover 11, are provided with 1 interior rotation of the housing defeated
Shaft 2, is provided with for supporting the bearing 8 of the output shaft 2, in the housing 1 in the upper end cover 10 and bottom end cover 11
Side wall is provided with two coils 4 staggered relatively, is passed through alternating current power supply so that alternation is formed between coil in the coil 4
Magnetic field, also include, for controlling the driving switch 5 of the ac power frequency, being fixedly installed sound on the output shaft 2
Answer the armature component 3 of the coil 4.There is gap between the armature component 3 and the coil 4, so that output shaft 2 can
The reciprocating motion of special angle can be carried out in the interstice coverage, above-mentioned special angle is between 2 degree to 7 degree.In the housing 1
Interior that trigger switch 9 is provided with outside 2 pendulum angle of output shaft, the trigger switch 9 is connected to housing by a support chip 9a
On inwall, support chip 9a has elasticity, when 2 pendulum angle of output shaft is abnormal, the armature component 3 on the output shaft 2 with
The trigger switch 9 is contacted.The anomalous swing angle is more than 9 degree.That is, when the vibrating motor of appliance for personal care is in abnormal
During angle swinging, trigger switch 9 can detect above-mentioned exception, so as to remind in time user to care implement carry out safeguard and
Maintenance（Prompting function is realized by trigger switch 9 is connected alarm unit or signal etc.）.
Also including an elastic inserted sheet 6,2 bottom of the output shaft is provided with groove 20, is provided with 20 bottom of groove and supplies institute
The slot 21 of the insertion of elastic inserted sheet 6 is stated, referring to Fig. 3, the slot 21 is provided with three, be provided with three accordingly and insert with described
The elastic inserted sheet 6 that groove 21 coordinates, described 6 one end of elastic inserted sheet are provided with the drive mechanism 7 for promoting the elastic inserted sheet 6（The drive
Motivation structure can select small cylinder or hydraulic cylinder etc.）, the drive mechanism 7 electrically connect with the driving switch 5 and should
Drive mechanism 7 is fixed on the housing 1, when driving switch 5 changes the alternating current power supply output frequency, the drive mechanism
7 control the elastic inserted sheet 6 inserts or departs from the slot 21.When driving switch 5 changes the alternating current power supply output frequency,
The drive mechanism 7 controls the elastic inserted sheet 6 and inserts or depart from the groove slotting 21.Specifically, can be by the intrinsic of output shaft 2
Frequency configuration is to be consistent with the output frequency of the less gear of coil, is located at the shelves in the whole machine output frequency of appliance for personal care
During position, as 2 natural frequency of output shaft and 4 natural frequency of coil are consistent, and now elastic inserted sheet is not inserted into positioned at defeated
In the groove that 2 bottom of shaft is arranged, in the less gear, coil output frequency ensure that the frequency with vibrating motor output shaft
Reach unanimously, so as to reach resonance so that the vibration of vibrating motor is sufficiently transferred to care implement brush position；When using shelves
While the output frequency of coil is modulated larger gear by bit switch 5, drive mechanism 7 receives the letter of the change of above-mentioned driving switch 5
Number, so as to band dynamic elasticity inserted sheet 6 is moved to 21 direction of slot, and entrance is arranged in the slot 21 that 2 bottom of output shaft opens up,
So that output shaft 2 is flexibly supported by elastic inserted sheet when special angle is rotated, output shaft is increased equivalent to by elastic inserted sheet
Natural frequency, above-mentioned setting ensure that when coil switches the output frequency of different gears, by by respective numbers reed
It is arranged in the slot 21 open up on output shaft 2 so as to ensure in different gears, coil output frequency is solid with output shaft all the time
There is frequency always consistent.
Listed above is only the specific embodiment of the present invention, it is clear that the invention is not restricted to the embodiment of the above.This area
The those of ordinary skill's all deformations that can directly derive from present disclosure or associate, all should belong to the present invention's
