When stator 30 30 coil 36 of stator be powered when, towards revolving meber 50 magnetic pole strength 544 polarity with quite high Frequency alternately change, so to the magnetic core 54 of revolving meber 50 formed direction alternately variation active force.It is with direction shown in Fig. 8 Example, when the soft magnetism chip 542 of the upside of the magnetic core 54 of revolving meber 50 is the poles N, and the soft magnetism chip 542 of downside is the poles S：Work as stator When the magnetic pole strength 38 of 30 two arms 342 is the poles S, driving magnetic core 54 rotates counterclockwise；Otherwise the magnetic of two arms 342 of stator 30 When pole-face 38 is the poles N, driving magnetic core 54 rotates clockwise.Similarly, if the soft magnetism chip 542 of the upside of magnetic core 54 is the poles S, downside Soft magnetism chip 542 be the poles N：When the magnetic pole strength 38 of two arms 342 of stator 30 is the poles S, driving magnetic core 54 rotates clockwise； When otherwise the magnetic pole strength 38 of two arms 342 of stator 30 is the poles N, driving magnetic core 54 rotates counterclockwise.

Due to the alternating current that electric current is high frequency variation, the change in polarity frequency of the magnetic pole strength 38 of stator 30 is quite high, magnetic The rotational angle of core 54 in any direction is very small and replacement of rotation direction is very fast, is so presented as the high frequency of magnetic core 54 It swings.Since magnetic core 54 is fixed in swing rod 52, and swing rod 52 is rotatably connected at by bearing on pivot 16, magnetic core High frequency swings cutting blade 100 of 54 swing with 52 other end of driven fork therewith, and head is cut with ledger-plate collective effect Hair.Preferably, the radian that the magnetic pole strength 544 of the revolving meber 50 is crossed over is slightly less than the arc that the magnetic pole strength 38 of stator 30 is crossed over Degree, in the range of so ensureing that revolving meber 50 is always positioned at magnetic pole strength 38 of stator 30 when swinging, stator 30 is to revolution Part 50 has better active force.

In a specific embodiment of the present invention, hair-cutting machine using when its cutting blade 100 swing 1.5-2.0 Tooth, tooth pitch 2.5mm, swing rod 52 and the pendulum radius of cutting blade 100 are 26mm：It is swung tooth according to cutting blade 100 first Number is with tooth pitch it was determined that the distance that swings is 3.75-5.0mm；Then according to the pendulum radius of 26mm it was determined that left and right Swinging distance is that the swing angle corresponding to 3.75-5.0mm is 4-5.5 degree, it is seen that swing angle is very small, swings camber line almost It is straight line.

Preferably, the utility model vibrating motor is additionally provided with elastic component 70 in the both sides of its revolving meber 50, for limiting pendulum The angle of the swing of bar 52.The elastic component 70 can be compressed spring, flat spring, torsional spring or shrapnel etc..Preferably, institute It states elastic component 70 to be located in shell 10, and the setting of 54 position of corresponding magnetic core.In the present embodiment, the elastic component 70 includes two Compressed spring is symmetrically disposed on the both sides of swing rod 52.One end of each compressed spring 70 is resisted against the side of swing rod 52, another End is resisted against in shell 10.In the present embodiment, the upper cover 14 of the shell 10 is respectively formed with a card slot 18 in its both sides, to pressure One end of contracting spring 70 is limited.The swing rod 52 is respectively formed a groove 520 in its both sides, is used for and compressed spring 70 The other end limited.After assembly, the both ends of each compressed spring 70 are placed in the groove 520 and shell of swing rod 52 respectively 10 correspond in the card slot 18 of side.

When the energization of the coil 36 of stator 30 makes magnetic core 54 swing, the elastic component 70 of side, while the bullet of the other side are compressed Property part 70 restore deformation push magnetic core 54 quickly swing.Preferably, the force variation of the elastic component 70 is a photograph elasticity system Count or so, under the tooth pitch that elastic component 70 is swung required for above-mentioned specific embodiment, that is, swing 1.5-2.0 tooth, tooth pitch For 2.5mm, swing rod 52 and cutting blade 100 pendulum radius be 26mm in the case of, the displacement of swing is 0.8-1.2mm, so It is 4-5.5 degree to drive the angle that cutting blade 100 is swung.It is to be appreciated that the displacement of elastic component 70 can be according to cutting blade 100 The specific angle of required swing is arranged accordingly, when swing angle smaller, can choose the larger bullets of coefficient of elasticity k Property part 70；Otherwise when swing angle bigger, the relatively large elastic components of coefficient of elasticity k 70 can be chosen.

The utility model vibrating motor directly drives the magnetic of revolving meber 50 by the magnetic fields of stator 30 and revolving meber 50 Core 54 is swung.And magnetic core 54 and the assembly of swing rod 52 are in a complete revolving meber 50, by the leverage of swing rod 52, directly It drives cutting blade 100 to swing, eliminates the friction that cam tracking mechanism is brought, vibration and noise.In addition, the revolving meber 50 Magnetic core 54 by its permanent magnet 540 polarize two soft magnetism chips 542, realize two magnet function, keep structure more reliable.Again In addition, the revolving meber 50 and the magnetic pole strength 38 of stator 30 are arc surface, uniform air gap is formed between the two so that revolution The rotation of part 50 is more steady, and revolving meber 50 is effectively reduced with the empty slot 39,544 on the magnetic pole strength 38,544 of stator 30 Slot effect keeps the rotation of revolving meber 50 more smooth.In this way, the hair-cutting machine using the utility model vibrating motor uses More steady, quiet, usage experience is more comfortable, and service life also significantly improves.

It should be noted that the utility model is not limited to the above embodiment, creation essence according to the present utility model God, those skilled in the art can also make other variations, these variations done according to the creative spirit of the utility model, all It should be within the scope of the utility model be claimed.
