Description
[technical field]
The present invention relates to a kind of cutter head structures of rotation razor.
[background technique]
Rotary electric shaver is typically all to be made of knife net and rotary cutter, and wherein knife net includes and skin contact
Face body and cylinder for assembly form, and according to inside and outside rotary cutter, have corresponding inner ring in the online drawing and forming of knife
Cutter groove and outer ring cutter groove, to cooperate the circumgyration incision of rotary cutter.And to ensure after the molding of inner and outer rings cutter groove, and molding
Each cutter groove neat and consistent just can guarantee and preferably be bonded realization shearing hair with rotary cutter, causes its manufacturing forming process
Complexity, and face body and cylinder are structure as a whole, this knife net integral structure, and the part of face body and facial contact needs to accomplish very
It is thin, to guarantee the effect that shaves, and as the mechanical strength supported and the cylinder of installation needs to have certain, it is typically necessary and reaches
To certain thickness, process is typically necessary by multi-drawing technique, and manufacturing process is complicated, and difficulty of processing is big, production
Low efficiency, manufacturing cost are high, and it is bad to be easy to produce crackle etc..
Patent No. CN201320552400, the combined knife net and turn shaver of entitled turn shaver are open
Solve face body and cylinder be structure as a whole existing defect the technical issues of a kind of technical solution, i.e., using mutually independent
Face body and the equipped composition of cylinder, in conjunction with specification and its attached drawing, technical solution specifically: Assembly interface is set on the body of face,
The step fixed in cylinder internal diameter and with cylinder internal diameter cooperation is protruded into setting on Assembly interface.Body and cylinder are metal face to face
When part, laser welding can be passed through by being fixedly connected；Body is that metalwork can pass through injection molding when cylinder is plastic parts face to face
It is mutually fixed.Although the patented technology solves face body and cylinder and asks since the inconsistent bring manufacturing process of thickness is complicated difficult
Topic, but equally exist following defect:
1, drawing and forming has cutter groove on the body of face, to ensure cutting effect, wants neat and consistent after need to guaranteeing cutter groove molding, causes
Its manufacturing forming process is complicated.
2, face body similarly increases with the fixation of cylinder in such a way that Assembly interface setting step is matched with cylinder internal diameter
Add the stretch forming process of the interface step structure, and the structure inside contracts interface step from outer ring cutter groove lateral wall,
Interface step is kept off in the lower section of outer cutting ring slot, then increases the molding difficulty of outer ring cutter groove or interface step, the manufacture of face body
Complex process；Moreover, the interface step inside contracted causes positioning of the face body in injection mould multiple when using injection molding process
It is miscellaneous, prevent the resistance plastic structure inside plastic cement solution entering surface body complicated, therefore, injection molding process is complicated, and manufacturing cost is high.
3, the lateral wall of outer ring cutter groove is located above cylinder, and since face body material is relatively thin, intensity is low, is easy to cause face body
Top surface and the lateral wall of outer ring cutter groove collapse in external collision, cause the dilapidated of entire knife net.
4, the structure leads hair and into hair structure and without any improvement for existing outer knife net.
The present invention is namely based on what such case was made.

The cutting region of docking, so that outer knife 41 be made to realize all standing shearing to the region between interior knife 43.
Wherein, the intermediate cutter 42 can be made of the identical one group of cutter of the radius of gyration, can also be by more than two
The different cutter composition of the radius of gyration.When intermediate cutter 42 is made of the different cutter of the radius of gyration more than two, adjacent two
Cutting region seamless interfacing between group cutter.
There are two the outer knives 41 and relative rotation center is symmetrical, and there are two simultaneously relative rotation centers pair for the interior knife 43
Claim, the intermediate cutter 42 there are two and relative rotation center it is symmetrical, improve cutting efficiency, further, the outer knife 41, in
Between cutter 42 and interior knife 43 be staggered at an ang around rotation center circumferential array, so as to the supporting surface body 1 of symmetrical equilibrium,
The non-deformability of raising face body 1.
The face body 1 and cylinder 2 be mutually independent two components and be fixedly connected, and the outside of the face body 1 is to next
The body formed interconnecting piece 3 having for connecting with cylinder 2 is equipped with strip into hair slot between the edge and interconnecting piece 3 of the face body 1
11, the outer peripheral surface of 2 upper end of cylinder is equipped with outwardly protruding and form comb structure leads mao tooth 21, the interconnecting piece
3 are fixed on the root for leading mao tooth 21, led described in two be equipped between mao tooth 21 communicated with into hair slot 11 lead mao slot 22, it is described
It leads mao slot 22 and is formed into hair slot 11 outer into pore 20.Mao tooth 21 of leading is uniformly arranged around 2 circumferencial direction of cylinder, described to lead hair
Tooth 21 can comb hair, for contacting skin and beard more preferably to be led mao slot 22 and to be entered inside cutter head into hair slot 11
For cutting.
And by being integrally formed out interconnecting piece 3 downwards in the outside of face body 1, it is connected and fixed by interconnecting piece 3 with cylinder 2,
Simplify the knife web frame that face body 1 and cylinder 2 form, and connection structure is simple, can be avoided and is formed between face body 1 and interconnecting piece 3
The step protruded from outside to inside, moulding process are simple.
The top surface rounding off of the top surface for leading mao tooth 21 and face body 1, interconnecting piece 3 are entirely incorporated in the root for leading mao tooth 21
In portion, and face body 1 only has top surface to expose, and structural strength is more preferable, and the top surface for leading mao tooth 21 is contacted as with skin and beard
A part, then improve shaving comfort.
The head for leading mao tooth 21 is equipped with guide angle, and the Carding Function of mao tooth 21 is led in enhancing.
The face body 1 is made of metal material.
The cylinder 2 is made of plastic material, the interconnecting piece 3 in 2 injection molding of cylinder with lead the root of mao tooth 21
In conjunction with fixation.This kind of connection structure is easy to positioning of the face body 1 in injection mold, by upper and lower in 2 injection molding of cylinder
Molding production can be realized to slotting module, simplify the structure of injection mold.
The interconnecting piece 3, which is equipped with to outwardly protrude, is leading the knot for increasing the binding force of face body 1 and cylinder 2 inside mao tooth 21
Close tooth 31.The protrusion of conjunction gear 31 is being led inside mao tooth 21, then the binding force for increasing interconnecting piece 3 and cylinder 2 simultaneously, avoid increasing
Add the thickness of 2 barrel of cylinder, saves material.
Another embodiment as shown in Figure 5, the cylinder 2 are made of metal material, and the interconnecting piece 3, which is welded on, leads hair
On the root of tooth 21, and after welding to 6 polishing grinding of weld part, simple process, structural strength is good.
The cutter head structure structure of rotation razor of the invention is simple, and simple production process is easy to produce and process.
