Detailed description of the invention
First with reference to Fig. 1-4 of accompanying drawing, speak briefly the traditional hair clipper device P understood according to prior-art devices.The main parts of the hair clipper device P shown in Fig. 1 and Fig. 2 of accompanying drawing comprise drive unit 1 and cutting head 2, on the framework that described drive unit 1 and described cutting head 2 are both arranged on device P or in housing 3, its middle frame or housing 3 are illustrated with the profile cut open in FIG.As those of ordinary skill in the art be familiar with, the framework of hair clipper device P or housing 3 be typically formed at hair-clipping operation during be kept by the hand of user.
Drive unit 1 comprises motor 4, and described motor 4 is fixedly mounted in housing 3 power supply that also can be designed to battery and provide the operation of power or connect for cable.The rotor of motor 4 has driving shaft 5, and described driving shaft 5 is driven in rotation around central rotation axis 6.The cutting head 2 of hair cutter P is arranged on the far-end of housing 3, and comprise first fixed blade component 7 and the second removable blade component 8 fixing relative to housing 3, described second removable blade component 8 to be positioned on the first blade members 7 and to be designed in side direction or to move back and forth relative to the first blade members 7 in a lateral direction, and two blade members 7,8 are cooperated to produce shear action between described two blade members 7,8.In this, the first blade members 7 has general planar or platy structure, and the second blade members 8 is arranged on the upper surface of the first blade members.As seen from Fig. 3 of accompanying drawing, each in blade members 7,8 comprises before cutting head 2 or costal field 11 forms multiple parallel tooth-like part or the forked portion of pectinate structure.When (namely the tooth-like part of the second blade members 8 or forked portion 9 move around relative to the tooth-like part of the first blade members 7 or forked portion 9 in a lateral direction, move back and forth) time, the shearing of any hair that shear action impact is outstanding between the comb elements of blade members 7,8.
Second blade members 8 is produced by the transmission mechanism between motor 4 and movable vane component 8 relative to the reciprocating motion of the first blade members 7.As prior brief as described in, circular columns bolt or pin component 12 prejudicially or depart from the axle that rotation 6 is connected to motor 4, and are parallel to rotation 6 and extend towards the second blade members.The transmission part 13 be arranged on the second blade members 8 comprises slit 14, and the size of described slit 14 is formed circular columns bolt or pin component to be snugly contained between the right side surface of the parallel surface of described slit 14.This is especially clear that from Fig. 3 and Fig. 4 of accompanying drawing, wherein Fig. 3 with Fig. 4 shows column bolt or pin 12 is formed to make column bolt or pin 12 on horizontal lateral, contact the sidepiece of slit 14 with the size of slit 14, and slit 14 is vertically or direction upper shed up and down.
Because column bolt or pin component 12 bias are fixed to motor shaft 5, therefore sell component 12 and record when the shaft is rotated around the figures of axis 6.Therefore, column bolt or pin and slit 14 interact in the following manner in transmission part, which comprises: transverse direction or the lateral movement of pin component 12 are directly passed to the second blade members 8, and in slit, produce the movement of pin 12 on vertically or up and down direction, and do not need any significant transmission of arriving blade members 8 in said direction.In addition, helpful is in this pair spring element 15, and described spring element bias voltage second blade members 8 is to contact with the first blade members 7 and to suppress the movement of the second blade members 8 on any direction except lateral.
