Description

Reciprocating type hair clipper

The utility model relates to beauty appliance, specifically a kind of hair clipper.

Electric hair cutter is the hair dressing tools that people use always.Common electric hair cutter mainly is made up of last bottom knife, drive unit and switch etc., can be divided into two types of Electromagnetically vibrating and electrodynamic types according to the structure difference of drive unit.The Electromagnetically vibrating electric hair cutter adopts AC power, and after the energising, iron-core coil produces alternating magnetic field, under its effect, permanent magnet swings, and drives cutter and produces cutting movement, the electric hair cutter of this structure, drive unit power is big, and the external form volume is bigger, air gap maximum when permanent magnet is rocked to end position, magnetic resistance is also maximum, electric current in the coil is just bigger, and coil temperature will raise, and therefore is unfavorable for long-term use continuously; The electrodynamic type electric hair cutter adopts and exchanges the series excitation type motor, conversion by worm and gear drives fork and makes to rotatablely move and be converted to reciprocating motion, fork drives cutter again along the reciprocating generation cutting of bottom knife, such electric hair clippers structure complexity, and volume is also bigger.Above-mentioned existing two kinds of electric hair cutter power are big, complex structure, and overall dimensions are bigger; And adopt 220 alternating currents to be unfavorable for safety, and guarantee its security performance, must adopt reinforced insulation, increased the volume of product conversely again.Therefore it only is applicable to the pruning of hair or hair on the temple, and the modern more and more pays attention to the image of self, also be sent in higher requirement for beauty treatment, prune eyebrow, shave off nose, ear, chest etc. and locate unnecessary hair, even on hair, repair out the style of the own individual character of various representatives and style and also push away and be fashion, the traditional electric hair cutter particularly shuttle instrument of the latter then is difficult to satisfy this generic request.

The purpose of this utility model is the hair clipper that a kind of special use will be provided, it has overcome shortcomings such as traditional electrical clipper complex structure, volume be bigger, its voltage safe in utilization, compact conformation, overall dimensions are little, can prune the unnecessary hair of human body everywhere, also can on hair, prune out the modish hair style of various patterns.

The purpose of this utility model is achieved in that reciprocating type hair clipper, comprise that casing, drive unit, termination have the cutter and the bottom knife of groove sword, it is characterized in that described drive unit mainly is made up of motor, fork, tension force swing arm and guide pad, described motor output shaft is an eccentric shaft, is embedded in the vertical groove that the fork afterbody offers; The rear end inlay card of described tension force swing arm is on fork, and the set downward dome of its front end snaps in the kidney slot of offering on the guide pad; Described guide pad bottom is provided with two fins, and described cutter just in time snaps between two fins at its width, in the groove that described fin embedding bottom knife upper surface is offered.

Motor output shaft of the present utility model adopts eccentric shaft, the perpendicular connected in star of offering by the fork afterbody, be converted into swinging of horizontal direction with rotatablely moving, should be moved by fork is passed to tension force swing arm, guide pad successively again, and it is reciprocating along bottom knife to drive cutter at last.Compare with the traditional electrical clipper, it directly adopts eccentric shaft, omitted a cover eccentric stiffener that constitutes by worm and gear, therefore simple in structure, compact to design, reduced the overall dimensions of product widely, especially make the size of blade can be designed to very little, therefore, it can be pruned the unnecessary everywhere hair of human body, can also prune out various patterns on hair.

Guide pad of the present utility model matches with tension force swing arm, cutter, bottom knife respectively, not only play the guiding role, and itself also is the drive unit of cutter, will drive and guiding unites two into one, and eliminates unnecessary gap, reduces noise and vibration; Set two fins in guide pad bottom snap in cutter wherein, and guide pad is led outside the cutter width by left and right sides fin, and it is more steady reliable to lead, and can not occur the situation of cutter perk on one side when commutation.

Be the cooperating of tension force swing arm and guide pad to snap in and finish in the waist circular trough of guide pad by the set downward dome of tension force swing arm head, and the arm body of tension force swing arm just in time is pressed on the guide pad, by the compressing guide pad, make upper and lower blade keep certain pressure, thereby omitted independent pressure elements (as spring, sheet spring etc.), pressure elements and driving fork are united two into one, make structure simpler, also be easy to assembling manufacturing.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the partial sectional view of drive unit among the utility model embodiment.

Fig. 3 is the partial cutaway diagrammatic sketch of cutter head part among the utility model embodiment.

Fig. 4 is the utility model course of work schematic diagram.

Fig. 5 is the schematic diagram that Fig. 4 cutter is rocked to a termination.

With reference to Fig. 1; reciprocating type hair clipper; by casing 1; drive unit; the cutter 10 and the bottom knife 11 that have the groove sword with the termination constitute; drive unit is by motor 6; fork 7; tension force swing arm 8 and guide pad 12 are formed; motor 6 adopts direct current permanent magnet motor; output shaft is an eccentric shaft 13; successively with fork 7; tension force swing arm 8; guide pad 12; cutter 10 joins end to end; bottom knife 11 is fixed on the casing head by screw 9; be provided with battery compartment in the casing 1; battery 2 is installed as motor power in the battery compartment; also be provided with switch on the casing 1; switch is by negative plate 3; positive plate 4; lead 5 is connected with battery-electric motor loop, and cutter head is provided with and protects the tooth cover, is not collided in order to dustproof and protection blade teeth groove.

With reference to Fig. 2,3, fork 7 afterbodys have vertical groove 22, the eccentric shaft 13 of motor 6 embeds in the groove 22, when motor 6 energisings are rotated, eccentric shaft 13 produces eccentric rotary, eccentric shaft 13 can move up and down along groove 22 relative forks 7, and the motion of its horizontal direction then drives fork 7 and swings together; Fork 7 middle parts are provided with bayonet socket 15, and head is provided with waist shape boss 16, and tension force swing arm 8 afterbodys are provided with dop 14, and the middle part is provided with the waist connected in star, and this waist connected in star snaps in the waist shape boss 16, and dop 14 snaps in the bayonet socket 15, and tension force swing arm 8 reliably is connected with fork 7; Fork 7 links to each other with casing 1 by a fulcrum 18 at boss 16 places, and fork 7 can be around this fulcrum swing.
