Description

Separable reciprocating type cutter head

Technical field

The present invention relates to the shaver technical field, relate in particular to a kind of separable reciprocating type cutter head.

Background technology

Along with the development of shaver technology, the function of shaver and performance have also obtained very big improving and raising, yet with regard to present common various style shavers, it still has the place that haves much room for improvement.Such as common separable reciprocating type cutter head, traditional swinging structure comprises a pair of symmetrical swing span and output shaft, and the eccentric wheel of symmetry is set in rotating shaft; Realize the driving of eccentric wheel to swing span through connecting rod and the hinged mode of swing span then, a blade is installed in respectively on two swing spans, under the drive of swing span, cooperatively interacts to realize shaving effect; Also there is weak point in actual use in this rocking bar swinging structure: this rocking bar swinging structure is had relatively high expectations to assembly precision, and comparatively complicacy is installed, and is not easy to maintenance; Between long-time use back link and eccentric wheel and between connecting rod and the swing span, all take place easily loosening the manifesting of wearing and tearing; Influence the precision that swings back and forth of swing span, dislocation can take place and manifest in the cooperation between the blade, and the quality of fit of blade is also just not enough; The effect that shaves is undesirable; And after wearing and tearing occurring, the oscillating quantity of two swing spans also tangible difference can occur, can cause that bigger vibration takes place for connecting rod and swing span; Produce bigger noise, the comfortableness that shaver uses is relatively poor.

Summary of the invention

For solving above-mentioned technical problem, the present invention provide a kind of simple in structure, be easy to assemble, working stability and use comparatively comfortable separable reciprocating type cutter head.

Technical scheme of the present invention is; A kind of separable reciprocating type cutter head with following structure is provided; It comprises shell, preceding swing span, back swing span, rotating shaft and palpus cutter; Preceding swing span is installed on the shell with the back swing span, and rotating shaft is provided with eccentric wheel and following eccentric wheel, and last eccentric wheel is that the identical circle of diameter is taken turns with following eccentric wheel; The both sides that last eccentric wheel and following eccentric wheel are positioned at rotating shaft are and are symmetrically arranged; Before swing span be equipped with the swing mating groove with the back on the swing span, last eccentric wheel is free to rotate be engaged in before in the swing mating groove on the swing span and go up eccentric outer wall and be close to the inwall of this swing mating groove, following eccentric wheel is free to rotate be engaged in after swing mating groove inwall interior and following eccentric outer wall and this swing mating groove on the swing span be close to.

After adopting said structure, the present invention has following remarkable advantage and beneficial effect:

The eccentric wheel of circle wheel construction is all very simple with swing mating groove structure, only need guarantee during installation up and down two eccentric centers of rotation identical and about get final product in the bilateral symmetry of rotating shaft, and the structure of swing mating groove is just more simple; The eccentric wheel of circle wheel construction is stuck in the swing mating groove just, and there is not the swing gap between the two in eccentric wheel when in the swing mating groove, freely rotating, and swing span is followed eccentric wheel all the time and moved; Assemble very conveniently, reduced the space of cutter head to greatest extent, itself has also avoided the appearance of loosening phenomenon this structure; Reliability is better; Stability during work is also just than higher, and when eccentric wheel drove the swing span swing, swing span just can not shake; Noise when having effectively reduced work has comfortableness preferably during use.

As improvement, it comprises also and being used for and the fuselage connector of fuselage flexible connection and the rotational connector that is used to be connected motor output shaft that the fuselage connector is installed in the lower end of shell, and rotational connector is positioned at the fuselage connector and is connected with rotating shaft.Cutter head with swing span swinging structure among the present invention can use in the shaver of various structures; It has stronger adaptability, adopts cutter head and blade isolating construction more to help the cleaning to cutter head, and; Its inside of cutter head of the present invention does not have circuit structure; Can carry out whole body washing to it fully, clean comparatively easy and help thoroughly cleaning, need not fuselage is carried out clean; Just need not that so also fuselage is carried out waterproof sealing and handle, help reducing the production cost of shaver.

The specific embodiment:

Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.

Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7; The separable reciprocating type cutter head of the present invention; It comprises shell 1, preceding swing span 2, back swing span 3, rotating shaft 4 and palpus cutter 5, must be installed in respectively on preceding swing span 2 and the back swing span 3 by cutter 5, and is identical with prior art; Preceding swing span 2 is equipped with U type linking arm with the both sides of back swing span 3; Preceding swing span 2 all is installed on the shell 1 through this U type linking arm with back swing span 3, and this U type linking arm has certain elasticity, helps keeping swing span and keeps uniform and stable in swing process.

Rotating shaft 4 of the present invention is provided with eccentric wheel 6 and following eccentric wheel 7; It is the double eccentric wheel structure; Wherein, Last eccentric wheel 6 and following eccentric wheel 7 are the identical circle wheel of diameter, and the both sides that last eccentric wheel 6 and following eccentric wheel 7 are positioned at rotating shaft 4 are and are symmetrically arranged, and make eccentric wheel 6 and following eccentric wheel 7 have common pivot; Be equipped with swing mating groove 8 on preceding swing span 2 and the back swing span 3; Two swing mating groove 8 two-layer one on the other arranged alternate, last eccentric wheel 6 and following eccentric wheel 7 respectively with preceding swing span 2 with after swing mating groove 8 work that matches on the swing span 3, concrete; Last eccentric wheel 6 is free to rotate be engaged in before in the swing mating groove 8 on the swing span 2 and the outer walls of going up eccentric wheel 6 be close to the inwall of the both sides of this swing mating groove 8, the outer walls that are engaged in swing the mating groove 8 interior and following eccentric wheels 7 on the swing span 3 of back that following eccentric wheel 7 is free to rotate and the inwall of these swing mating groove 8 both sides are close to.When rotating shaft 4 is rotated, last eccentric wheel 6 and following eccentric wheel 7 rotates simultaneously drive the moving frame 2 of forward swing with after the swing span 3 synchronous backwards reciprocating motion realization effect that shaves.

Technical scheme of the present invention has the scope of application preferably; In the shaver of various structures, all can use; With the example that is applied as in split type shaver: serve as realize fuselage and cutter head smooth dock and fuselage in motor can drive the rotating shaft rotation smoothly; Cutter head of the present invention also comprises and being used for and the fuselage connector 9 of fuselage flexible connection and the rotational connector 10 that is used to be connected motor output shaft; Fuselage connector 9 is installed in the lower end of shell 1, and rotational connector 10 is positioned at fuselage connector 9 and is connected with rotating shaft 4.Realize being connected of reliable and stable of cutter heads and fuselage by fuselage flexible jumper 9, be connected with the output shaft of motor by rotational connector 10 then, realization driven by motor rotating shaft 4.This syndeton is a routine techniques, this no longer tired stating.

Need to prove: " preceding " before above-mentioned in swing span 2 and the back swing span 3, " back " can not be regarded the qualification to its position as just in order to narrate needs easily.
