The specific embodiment
Below in conjunction with accompanying drawing 2-3 and specific embodiment, further set forth the utility model.These embodiment be interpreted as only being used to the utility model is described and be not used in the restriction protection domain of the present utility model.After the content of having read the utility model record, those skilled in the art can make various changes or modifications the utility model, and these equivalences change and modification falls into the utility model claim institute restricted portion equally.
At first, based on Fig. 2-3, the overall structure of the electric shaver that the utility model one preferred embodiment provides is described.Electric shaver is made of over cap 1, outer cutter screen component 2 and shaver body 3, two outer cutter net boxes 4 are set on the cutter screen component 2 outside, shaver body 3 inside have motor, conducting subassembly, battery and circuit element (not indicating among the figure) simultaneously, during press button 5 on pressing shaver body 3, battery provides power source 12 to motor, and motor produces circumference and rotatablely moves; Power upwards is delivered to two interior cutter heads 6 by conducting subassembly, the power conduction orientation is shown in arrow among the figure, because the transmission of power direction is positioned at the centre of cutter head 6, thus interior cutter head 6 when outer cutter net 7 on the outer cutter net box 4 contacts, the contact stress maximum of central portion; Simultaneously, because when shaving, the frequency of utilization of cutter net pars intermedia is the highest, the blade of central portion is the easiest to bend, is out of shape, the sharpness and the tonequality that shaves that this shaves influence.
As shown in Figure 4, interior cutter head 6 is made of metal comb 8 and interconnect 9.Metal comb 8 is formed after by punching press, bending, surface treatment and grinding by a slice comb shape stainless steel metal sheet.Obtain optimum sharpness, the tonequality that shaves and more lasting service life, metal comb 8 is designed to the knife number of odd number, and knife number is 29 in the present embodiment, on the blade in the middle of its center line just is positioned at.
Shown in Fig. 5 A, 5B, 5C and 5D, metal pectination blade thickness is designed to 0.2-0.4mm, and its amplitude is 0.3-0.6mm, and the interval between blade is (Fig. 5 A) between 1.2-1.4mm, and it is smaller to be designed to midfeather, both sides at interval big (Fig. 5 B); Simultaneously, (Fig. 5 D) is formed with 30 °-60 ° section (Fig. 5 C) in the scope of metal comb angle between 90 °-140 ° of its side surface direction, and this acute angle section effectively improves the sharpness of shaver.
Simultaneously, need before the bending of metal comb or after the bending blade heat-treat or other surface treatments with reinforcing material hardness (hardness requires more than 500HV), anticorrosion, wear resistance etc., to improve its serviceability, service life; And acute angle section that must blade carries out further grinding, better to be cut off the acute angle tip.
The interconnect 9 of cutter head in then illustrating.The interconnect 9 of interior cutter head has the function of maintenance metal pectination blade shapes and the effect of transferring power.Interconnect in the present embodiment differs by the plastics fixing point height on its installation portion, forms easy embedded structure (shown in Fig. 6 B, Fig. 6 A is depicted as the existing structure schematic diagram), and this installing mechanism has easy for installation, the advantage that operating efficiency is high.Can guarantee the accurate location of metal blade and interconnect by embedded structure, assurance the shave sharpness and the tonequality that shaves, simultaneously, for the firmness of reinforcement metal comb and interconnect, present embodiment adopts the method for thermo-compressed further to make pectination metal blade and interconnect fix (as Fig. 7 A, Fig. 7 B) behind embedding operation.
And the interconnect of above-mentioned electric shaver inner blade has sidewall reinforcing muscle 10 (shown in Fig. 8 B, Fig. 8 A is depicted as the existing structure schematic diagram) in the present embodiment, with the integral rigidity of cutter head in improving.
In addition, the metal comb of electric shaver inner blade has a semicircle osculum 11 at bottom position, during as the bending of blade U-shaped, prevents the identification marking (as shown in Figure 9) of blade inward-outward direction mistake.Design has such identification marking can effectively improve the efficient of buckling work and avoids occurring the bending direction mistake.
Electric shaver inner blade in the present embodiment is tested when 7000RPM is above at motor rotary speed, and the test life-span of interior cutter head still reached more than 7 years.
