Abstract
The utility model relates to an improved external knife of electric razor, which comprises a main body, wherein the main body is a bent thin sheet and provided with a top surface and front and rear side surfaces, a plurality of knife holes are formed on the top surface, the lateral margins of every knife hole are formed into blades, the top surface adopts a curved surface protruding upwards, the top surface is thinner than the above motioned front and rear side surfaces, the front and rear side edges of the top surface are arranged inwardly at intervals relative to the front and rear side surfaces, and a step reinforcement surface is formed at the junction respectively. The utility model has identical thickness of the top surface and is easily processed, has greater endurance for the top surface due to the top surface structure and the structure for connecting the top surface with the front and rear side surfaces despite of the fact the top surface is thinner than the front and rear side surfaces, and has further reinforced function through punched reinforcement ribs.
Description
Technical field
The utility model relates to the electric razor knife structure, specifically is meant a kind of outer cutter of improved left-right swing type electric shaver.
Background technology
The basic principle of electric shaver is to be provided with to swing or the rotation of blade group below a guard, and when guard was attached on the skin, hair was stretched into by the through hole of guard, is cut off by blade.This guard is also referred to as outer cutter, and correspondingly the set of blades of guard below is called interior cutter.
Chinese patent discloses " a kind of outer knife structure of reciprocating electric razor " for No. 200720008255.8, it is elongated by the thin plate bending to be somebody's turn to do outer cutter, cross direction profiles is at the shaver head, have end face and side, end face comprises the blade part that two ends rib and interior thickness are thinned, and has some long slot bores and form blade on the blade part of end face.This kind structure mainly is to utilize the rib at side and end face two ends to play a supportive role, and is the difficult processing of part of interior thickness attenuate and utilize the part fluting formation blade of interior thickness attenuate, its shortcoming, and processing technology generates originally higher.
The utility model content
The utility model provides a kind of improved electric shaver outer cutter, and its main purpose is to overcome the difficult processing of outer cutter, the higher shortcoming of processing technology cost of existing similar electric shaver.
The utility model adopts following technical scheme: the outer cutter of improved electric shaver, comprise a main body, this main body is formed by the thin plate bending, have end face and former and later two sides, end face is arranged with a plurality of tool bores, and the lateral margin of each tool bore forms blade, described end face is the curved surface that raises up, the thickness of this end face is less than the thickness of described former and later two sides, and the forward and backward dual-side of this end face inwardly staggers with respect to described former and later two sides, forms ladder in the junction respectively and strengthens face.
The outer cutter of the electric shaver of aforementioned improved, its ladder is strengthened face and is connected with leading flank or trailing flank rounding off with described end face.
The outer cutter of the electric shaver of aforementioned improved, the groove of trend about its end face is provided with, the forward and backward both sides of this groove form the tool bore distributed area of two strips, and described tool bore is distributed in the tool bore distributed area.
The two ends in described each tool bore distributed area respectively are provided with the reinforcement that a punching press forms.
By above-mentioned description to the utility model structure as can be known, compare, the utlity model has following advantage: top thickness unanimity of the present utility model, processing easily with prior art; Though the thickness of end face is less than forward and backward two sides, the structure of end face and make this end face have bigger intensity with the syndeton of forward and backward two sides; The reinforcement that punching press forms can play further reinforcement supporting role.
Description of drawings
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is a side view of the present utility model.
The specific embodiment
The specific embodiment of the present utility model is described with reference to the accompanying drawings.
The outer cutter of improved electric shaver sees figures.1.and.2, and comprises a main body 10, and this main body 10 is formed by the thin plate bending, has end face 1 and leading flank 2, trailing flank 3.The curved surface of described end face 1 for raising up, it can be semi-cylindrical shape, also can be semiellipse cylindroid or other slick and sly curved surface, the thickness of this end face 1 is less than the thickness of described leading flank 2, trailing flank 3, the forward and backward dual-side of this end face inwardly staggers with respect to described leading flank 2, trailing flank 3, forms ladder in the junction respectively and strengthens face 51,52.This ladder is strengthened face 51,52 and is connected with leading flank 2, trailing flank 3 rounding ofves with described end face 1.
With reference to Fig. 1, the groove 11 of trend about described end face 1 is provided with, the forward and backward both sides of this groove 11 form the tool bore distributed area 12,13 of two strips, and each tool bore distributed area 12,13 is distributed with tool bore 14, and the lateral margin of each tool bore 14 forms blade.The two ends in each tool bore distributed area 12,13 are respectively equipped with the reinforcement 41 and 43,42 and 44 that punching press forms.
Outside the above-mentioned electric shaver of processing during cutter, thin plate bending with consistency of thickness is shaped earlier, and end face 1 is inwardly staggered with respect to leading flank 2, trailing flank 3, forms ladder and strengthens face 51,52, inside of cutter outside this, this end face 1 is inwardly protruded with respect to leading flank 2, trailing flank 3; And then the medial surface of this end face 1 carried out grinding, make its less thick.This processing mode is very easy to carry out.
Above-mentioned only is the specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
