Description

A kind of three ring stationary knife guards of rotary electric shaver

Technical field

The utility model relates to electric tool technical field, relates to the design and fabrication of electric shaver moving knife and stationary knife guard, is a kind of three ring stationary knife guards of rotary electric shaver.

Background technology

Shaver is the daily necessities that man almost will use every day.Rotary electric shaver owing to carrying, the instrument becoming more people and like easy to use.The form of rotary electric shaver mainly contains: monocycle double end shaver, monocycle three shavers, dicyclo double end shaver and dicyclo three shavers.Shave moving knife and stationary knife guard is its two main parts.

The working method of rotary electric shaver is: contacted with the skin of face of people the outside of stationary knife guard, promote back and forth, is then shaved off by the beard penetrated in stationary knife guard by moving knife atwirl in stationary knife groove.And existing dicyclo double end shaver or dicyclo three shavers have the following disadvantages.

(1) the interior outside of existing dicyclo double end shaver or dicyclo three shaver stationary knife guards is flat (see Fig. 1: be planar structure at the outer shroud 12 of guard main body 11 and inner ring 13, be provided with the tiny rectangle of linear pattern in planar structure and enter hair trap openings), the contact of itself and skin is straightened condition but not bowed state, not easily fit when promoting back and forth, easy generation resistance, makes the comfort deficiency shaved.

(2) hair trap openings of entering of existing dicyclo double end shaver or dicyclo three shaver stationary knife guards is the tiny rectangle structure of linear pattern, the function catching beard is not enough to some extent: can not catch beard instantaneously from different perspectives, and the number of times causing electric shaver to promote back and forth at skin of face increases.In addition, the hair trap openings of entering in stationary knife guard inner ring distributes less, on average only has 44 ~ 45 to enter hair trap openings, affects the seizure to beard and shearing.

(3) actual (real) thickness of existing dicyclo double end shaver or dicyclo three shaver stationary knife guard outer shrouds and inner ring is 0.1 ~0.12 millimeter, both, the beard that the rear face that shaves remains also had had nearly 0.1 ~0.12 millimeters long, thus the result of use affecting electric shaver.Therefore, existing dicyclo double end shaver or dicyclo three shavers structurally still can continue perfect.

Utility model content

The purpose of this utility model is to solve the problem, a kind of and the matching used three ring stationary knife guards of rotary three gyration cutter shavers are provided, it adopts outer shroud, middle ring and interior ring structure, and the thickness of three rings only 0.08 millimeters thick, outer shroud and middle ring being respectively equipped with 80 outer ends is that the outer shroud of slice shape enters hair trap openings and middle ring enters hair trap openings, guard main body top spherically structure, make shaving session more comfortable, shave better effects if.

For achieving the above object, the utility model have employed following technical scheme.

A kind of three ring stationary knife guards of rotary electric shaver, hair trap openings is entered containing guard main body, moving knife locating shaft and side, described moving knife locating shaft is arranged on the centre inside described guard main body, described side enters the side that hair trap openings is arranged on described guard main body top, it is characterized in that, the surface on described guard main body top is spherical structure; Described guard main body is provided with outer shroud, middle ring and inner ring, and described outer shroud, middle ring and inner ring are thickness≤0.08 millimeter on donut structure, their tops; It is that 0.25 millimeter of slice shape outer shroud enters hair trap openings and middle ring enters hair trap openings that described outer shroud and middle ring are provided with outer end, and the circular inner that described inner ring is provided with the arrangement in textured enters hair trap openings.

Further, described outer shroud and middle ring to be respectively equipped with >=80 outer ends are that the slice shape outer shroud of 0.25 millimeter enters hair trap openings and middle ring enters hair trap openings, described every bar outer shroud enters hair trap openings and middle ring, and to enter hair trap openings be all sheared edge.

Further, the height that described side enters hair trap openings is 1.1 millimeters, and there is the chamfering in 0.22 millimeter of fillet its underpart.

The good effect of three ring stationary knife guards of a kind of rotary electric shaver of the utility model is:

(1) setting of outer shroud, middle ring and inner ring, and outer shroud and middle ring to be respectively equipped with >=80 outer ends be in slice shape ring enter hair trap openings, the shaving efficiency of 20% can be improved.

(2) guard main body top spherically structure, thickness only 0.08 millimeters thick on outer shroud, middle ring and inner ring top, make shaving session make us more comfortable, shave better effects if: indirectly can improve the speed that shaves of 15%, and the residual beard after shaving is shorter than prior art 1/3.

(3) the utility model is through structural new design, achieve the comfortable veneer of electric shaver, efficiently shave, totally thorough, the long-lived effect of stationary knife guard, the speed that shaves of 35% can be improved generally, also save electric energy simultaneously: once charging or a packed battery after service time longer, reduce use cost, facilitate the application of rotary electric shaver.

Detailed description of the invention

Explain the detailed description of the invention of three ring stationary knife guards of a kind of rotary electric shaver of the utility model below in conjunction with accompanying drawing further, but it is noted that enforcement of the present utility model is not limited to following embodiment.

See Fig. 2.Three ring stationary knife guards of rotary electric shaver, containing guard main body 21, outer shroud 22, middle ring 23, inner ring 24, outer shroud enters hair trap openings 25, middle ring enters hair trap openings 26 and inner ring enters hair trap openings 27.Described guard main body 21 should adopt the thin material of stainless steel 3cr13 through mould punching, high-temperature heat treatment, then the thickness to 0.08 millimeter of grinding outer shroud 22, middle ring 23, inner ring 24 and final molding.Described guard main body 21 arranges three road donut structures---outer shroud 22, middle ring 23 and inner ring 24, they are the locating slot of moving knife, are again the guards into palpus.

The surface on described guard main body 21 top is spherical structure, thickness≤0.08 millimeter (see Fig. 3) on described outer shroud 22, middle ring 23 and inner ring 24 top.Described outer shroud 22 and middle ring 23 arrange outer shroud and enter hair trap openings 25 and middle ring enters hair trap openings 26, described outer shroud enter hair trap openings 25 and middle ring enter hair trap openings 26 for outer end be the thin strip structure (see Fig. 4, Fig. 5) of 0.25 millimeter.The circular inner that described inner ring 24 arranges the arrangement in textured enters hair trap openings 27.

It should be noted that in enforcement and should enter hair trap openings 25 and middle ring enters hair trap openings 26 by the slice shape outer shroud arranged on described outer shroud 22 and middle ring 23 described at least 80, every bar outer shroud enters hair trap openings 25 and middle ring, and to enter hair trap openings 26 should be all sheared edge structure.

Centre inside described guard main body 21 arranges moving knife locating shaft 28(see Fig. 6).Arrange described side at the side on described guard main body 21 top and enter hair trap openings 29, described side enters hair trap openings 29 and in fact enters hair trap openings 25 with described outer shroud and be communicated with, and becomes the outermost end portion that outer shroud enters hair trap openings 25.The height that described side enters hair trap openings 29 is 1.1 millimeters, and the chamfering (see Fig. 7) in 0.22 millimeter of fillet should be arranged in its underpart.

The utility model, through structural new design, achieves the comfortable veneer of electric shaver, efficiently shaves, totally thoroughly, the long-lived effect of stationary knife guard, can improve the speed that shaves of 35% generally.
