Description

Has the seamless rotary shaver cutter head of the continuous four blade of orthodrome system
Technical field
The present invention relates to a kind of rotary shaver cutter head system.
Background technology
Existing rotary shaver cutter head on the market, its cutter net lateral surface generally all is right angle or little circular arc R, veneer poor effect, and be unfavorable for long must the entering causes and shaves not thoroughly, the efficient that shaves is low, and be prone to produce folder must, draw must pull out must defective; And its cutter net end face generally all has 2 to 3 or more spacer ring bars, and these spacer ring bars have reduced the limited usable floor area (about 30%) of cutter net, has so directly reduced the shave area and the efficient that shaves; Cutter net reference column generally all is the blind hole of tradition system simultaneously, causes the five metals mould very complicated, and traditional blind hole drawing numbers 7 to 8 times or more has increased manufacturing cost like this, and the outer garden precision of pillar is difficult to be guaranteed; Traditional on the market cutter net advances must groove must evenly not to arrange in the hole with advancing, and advancing must the hole or concentrate on inner ring, or concentration of local is unfavorable for comprehensive seizure of short hairs like this at two or three circles; Traditional on the market cutter net end face (advance must face) or be the plane, or be local arcuate surface, the veneer poor effect, and be unfavorable for long must the entering.
Existing rotary shaver cutter head on the market; Moving knife generally all by the spacer ring bar separately; Form independent; Fixed head disposable razor that is interrupted and blade and cutter net advance must generally all have gap and the slit about 0.2-0.4 between the groove, and the duration beard that shaves is had an opportunity to get into these slits and caused the folder palpus, draws the defective of must and pull out palpus.
Summary of the invention
Above-mentioned defective to prior art; The technical problem that the present invention will solve is to propose a kind ofly effectively to overcome traditional rotary shaver folder and must, draw that must and pull out must defective; It is high to catch palpus efficient, and veneer is effective, and can obtain better the to shave tonequality and the skin sense of shaving.
In order to solve the problems of the technologies described above; The present invention adopts following technical scheme: a kind of rotary shaver cutter head system; Comprise cutter net, first moving knife, second moving knife, balance fixed head and plastic cement connector, first moving knife is fixedly connected through Laser Welding with second moving knife; Balance fixed head and plastic cement connector are one-body molded through injection molding process, and are fixedly connected into the moving knife assembly through Laser Welding and first moving knife and four layers of blade of second moving knife; Cutter net inner face reference column be through hole and and plastic cement connector precision-fit; Cutter net lateral surface is a circular arc, and arc radius R >=2mm, cutter net lateral surface arrange evenly that serpentine or " C " shape advance must groove; Cutter net end face also is a circular arc, and circular arc is progressive ladder and increases, and increases amplitude >=0.30mm, cutter net end face evenly arrange serpentine different in size or " C " shape advance must groove with advance must the hole; First moving knife outside is circular arc, with cutter net precision-fit; First moving knife is provided with the 3rd layer of cutter, and the 3rd layer of blade also is circular arc, and with cutter net precision-fit; Second moving knife is provided with two groups of blades and forms second layer cuttves and the 4th layer of cutter, and second layer cutter and the 4th layer of cutter also are circular arc, and with cutter net precision-fit; The ground floor cutter spacing is in outermost, and second layer cutter, the 3rd layer of cutter and the 4th layer of cutter spacing are in the inboard; During rotation, second and third, the blade rotational trajectory continuous seamless of four layers of cutter arranges, and promptly constitutes the seamless fixed head disposable razor of big radian four blade.
Preferably, in the above-mentioned rotary shaver cutter head of the present invention system, cutter net end face is provided with two or more reinforcements, the height≤0.04mm of reinforcement.
Preferably, in the above-mentioned rotary shaver cutter head of the present invention system, ground floor cutter edge length is equal to or greater than cutter net serpentine or " C " shape is advanced the palpus groove.
Preferably, in the above-mentioned rotary shaver cutter head of the present invention system, cutting angle >=12 between the line of cut of first, second, third and fourth layer cutter and cutter net net groove °.
