Description

Separable reciprocating shaving head

Technical field

The utility model relates to the shaver technical field, relates in particular to a kind of Separable reciprocating shaving head.

Background technology

Along with the development of shaver technology, the function of shaver and performance have also obtained very large improving and improve, 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 shaving head, traditional swinging structure comprises a pair of symmetrical swing span and output shaft, symmetrical eccentric wheel is set in rotating shaft, then realize that by connecting rod and the hinged mode of swing span eccentric wheel is to the driving of swing span, one blade is arranged on respectively on two swing spans, cooperatively interact under the drive of swing span and 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, install comparatively complicated, be not easy to maintenance, use between back link and eccentric wheel and loosening the manifesting of wearing and tearing all easily occurs between connecting rod and swing span long-time, affect the precision that swings back and forth of swing span, dislocation can occur and manifest in the cooperation between blade, the quality of fit of blade also just not, the effect that shaves is undesirable, and after wearing and tearing occurring, the oscillating quantity of two swing spans also obvious difference can occur, can cause that larger vibration occurs for connecting rod and swing span, produce larger noise, the comfortableness that shaver uses is relatively poor.

Summary of the invention

For solving above-mentioned technical problem, the utility model provide a kind of simple in structure, be easy to assemble, working stability and use comparatively comfortable Separable reciprocating shaving head.

the technical solution of the utility model is, a kind of Separable reciprocating shaving head with following structure is provided, it comprises shell, front swing span, rear swing span, rotating shaft and palpus cutter, front swing span and rear swing span are installed on shell, rotating shaft is provided with eccentric wheel and lower eccentric wheel, upper eccentric wheel is the identical circle wheel of diameter with lower eccentric wheel, the both sides that upper eccentric wheel and lower eccentric wheel are positioned at rotating shaft are and are symmetrically arranged, be equipped with the swing mating groove on front swing span and rear swing span, the swing mating groove inwall interior and upper eccentric outer wall and this swing mating groove that is engaged on front swing span that upper eccentric wheel is free to rotate is close to, the swing mating groove inwall interior and lower eccentric outer wall and this swing mating groove that is engaged on rear swing span that lower eccentric wheel is free to rotate is close to.

After adopting said structure, the utlity model has following remarkable advantage and beneficial effect:

the eccentric wheel of circle wheel construction and swing mating groove structure are all very simple, only need guarantee during installation that two the eccentric centers of rotation in up and down identical and left and right gets final product in the bilateral symmetry of rotating shaft, and the structure that swings mating groove is just more simple, the eccentric wheel of circle wheel construction just is stuck in and swings in mating groove, do not exist between the two when eccentric wheel freely rotates in swinging mating groove and swing the gap, swing span is followed all the time eccentric wheel and is moved, assemble very convenient, reduced to greatest extent the space of cutter head, itself has also avoided the appearance of loosening phenomenon this structure, reliability is better, stability during work is also just higher, when eccentric wheel drives the swing span swing, swing span just can not shake, noise when effectively reducing work, has comfortableness preferably during use.

As improvement, it comprises that also the fuselage connector is arranged on the lower end of shell for the fuselage connector that is flexibly connected with fuselage and the rotational connector that is used for being connected motor output shaft, and rotational connector is positioned at the fuselage connector and is connected with rotating shaft.Cutter head with swing span swinging structure in the utility model can use in the shaver of various structures, it has stronger adaptability, employing cutter head and blade isolating construction more are conducive to the cleaning to cutter head, and, its inside of cutter head of the present utility model does not have circuit structure, can carry out the whole body washing to it fully, clean comparatively easy and be conducive to thoroughly clean, need not fuselage is carried out cleaning, just need not that so also fuselage is carried out waterproof sealing and process, be conducive to reduce the production cost of shaver.

The specific embodiment:

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, the utility model Separable reciprocating shaving head, it comprises shell 1, front swing span 2, rear swing span 3, rotating shaft 4 and palpus cutter 5, must be arranged on respectively on front swing span 2 and rear swing span 3 by cutter 5, same as the prior art, the both sides of front swing span 2 and rear swing span 3 are equipped with U-shaped linking arm, front swing span 2 and rear swing span 3 all are arranged on shell 1 through this U-shaped linking arm, this U-shaped linking arm has certain elasticity, is conducive to keep swing span and keeps uniform and stable in swing process.

rotating shaft 4 of the present utility model is provided with eccentric wheel 6 and lower eccentric wheel 7, it is the double eccentric wheel structure, wherein, upper eccentric wheel 6 is the identical circle wheel of diameter with lower eccentric wheel 7, the both sides that upper eccentric wheel 6 and lower eccentric wheel 7 are positioned at rotating shaft 4 are and are symmetrically arranged, make eccentric wheel 6 and lower eccentric wheel 7 have common pivot, be equipped with on front swing span 2 and rear swing span 3 and swing mating groove 8, two swing mating groove 8 two-layer alternately layout one on the other, upper eccentric wheel 6 and lower eccentric wheel 7 swing mating groove 8 work that matches respectively with on front swing span 2 and rear swing span 3, concrete, the inwall of the outer wall that is engaged in swing the mating groove 8 interior and upper eccentric wheels 6 on front swing span 2 that upper eccentric wheel 6 is free to rotate and the both sides of this swing mating groove 8 is close to, lower eccentric wheel 7 is free to rotate is engaged in swing mating groove 8 on rear swing span 3 and the inwall of the outer wall of lower eccentric wheels 7 and this swing mating groove 8 both sides is close to.When rotating shaft 4 was rotated, upper eccentric wheel 6 and lower eccentric wheel 7 rotate simultaneously the front swing span 2 of drive and the 3 synchronous backwards reciprocating motions of rear swing span realize shaving effect.

The technical solution of the utility model has the scope of application preferably, all can use in the shaver of various structures, take the example that is applied as in split type shaver: as realize fuselage and cutter head smooth dock and fuselage in motor can drive smoothly rotating shaft and rotate, the utility model cutter head also comprises for the fuselage connector 9 that is flexibly connected with fuselage and the rotational connector 10 that is used for being connected motor output shaft, fuselage connector 9 is arranged on the lower end of shell 1, and rotational connector 10 is positioned at fuselage connector 9 and is connected with rotating shaft 4.Realized reliable and stable being connected of cutter head and fuselage by fuselage connector 9, then be connected with the output shaft of motor by rotational connector 10, realize driven by motor rotating shaft 4.This syndeton is routine techniques, is not repeated at this.

Need to prove: the 'fornt', 'back' in above-mentioned front swing span 2 and rear swing span 3 just needs in order to narrate easily, can not regard the restriction to its position as.
