On the iron core of vibrating-type motor of the present utility model, some or whole described pole surface adopt and the predetermined angled inclined-plane of route.According to mathematical principle, hypotenuse is greater than right-angle side, the shortest apart from straight line between 2.Therefore, compared with prior art, under the width of air gap situation identical with the degree of depth, total gas length obviously extends, and has reduced power consumption and kinetic temperature, has further improved the efficient of motor with this.

Hair cutter with this motor can be operated under the lower temperature, produces bigger power output and shearing force; In addition, because motor uses coil turn to reduce, amount of copper consuming reduces, thereby has reduced manufacturing cost.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a kind of structural representation of the utility model hair cutter.

Fig. 2 is the armature of the utility model vibrating-type motor--the structural representation of assembly unshakable in one's determination.

Fig. 3 is this electronic preceding structural representation of sending out device of the prior art.

With reference to Fig. 1, static bottom knife 18 is fixed on support 13;

The upper blade 19 of motion is tightly obedient with described bottom knife 18, and links to each other with armature 12; The motor mounting that comprises coil 15, iron core 11 and described armature 12 is in described support 13.
