Abstract

The utility model relates to a mesh enclosure of a rotation-type single-head electric shaver, which comprises a circular top surface and a cylindrical surface which extends downwards from the periphery of the circular top surface, wherein four or more coaxial annular lug bosses are arranged on the periphery of the circular top surface from exterior to interior, the annular lug boss is respectively provided with a hair inlet hole, and an annular groove is arranged between two adjacent annular lug bosses. The mesh enclosure has the advantages that: a single-head form is adopted to substitute the present multi-head shaver, and not only better shaving effect can be realized, but also the cost is small; and compared with the present three-head shaver, under the condition that the circular top surface occupies the same area, the distribution of the hair inlet holes is more intensive, so the hair is convenient to enter.

Description

The guard of rotary single head electric shaver

Technical field

The utility model relates to a kind of shaver guard, is meant a kind of rotary electric shaver guard especially.

Background technology

The basic principle of electric shaver is below a guard set of blades to be set, and when guard was attached on the skin, hair was stretched into by the through hole of guard, and the blade of passive movement cuts off.

The motion mode of blade can be divided into parallel-moving type and rotary two kinds.The guard of rotary electric shaver comprises circular end face that a periphery is rounded and the cylinder that is extended by the periphery of this circle end face downwards, the outer peripheral part of this circle end face raises up, form the boss of an annular, the radial pore that advances is distributing on this annular boss.Rotatable set of blades is located at this annular boss below, and respectively advances the hair that pore cooperates cut-out to enter.

In order to increase the area that can Gong shave as much as possible, described in theory annular boss width is the bigger the better, but considers the too easy distortion depression in use of tolerance of annular boss, and it is unclean to cause shaving, therefore in order to prevent guard distortion depression, so the width of annular boss is less during practical application.

Nowadays the rotary electric shaver guard of selling on the market mainly contains two kinds.

First kind is the bull form, as the double end shaver, by increasing the number of turns of annular boss, the area that increase can Gong shave, but because the end face of each cutter head guard is less, thereby difficulty of processing is big, and three circles almost have been the limit, and the processing technology of this bull shaver has relatively high expectations, and cost is bigger.

Second kind is the single head form, and its circular end face is protruding sphere shape, and whole top is formed by soft guard, and its advantage is to substitute bull with single head, has reduced processing cost, but because the guard material is soft, occurs a folder hair phenomenon in use easily.

The utility model content

The utility model provides a kind of guard of rotary single head electric shaver, and its purpose is to overcome the above-mentioned defective of traditional rotary electric shaver guard.

The technical solution of the utility model is as follows: the guard of rotary single head electric shaver, comprise that a circular end face and is by the downward cylinder that extends of the periphery of this circle end face, described circular end face is provided with four or more coaxial annular boss from outside to inside from nearly peripheral position, be respectively equipped with into pore on the described annular boss, be provided with annular groove between the adjacent annular boss.

Described each annular boss is in the same plane.

The longitudinal section of described each annular boss radial direction is circular arc.

Described circular end face is protruding sphere shape.

By above-mentioned to description of the present utility model as can be known, compared with prior art, advantage of the present utility model is: adopt the single head form, because its end face is corresponding bigger, thereby accomplish four circle or multi-turns more easily, compare with the bull shaver and can not only reach the effect that better shaves, and cost is littler; Compare under circular end face area occupied same case with three shavers, advance pore and distribute closelyer, and more help into hair; Be set to arc by annular boss along the cross section of radial direction, can make annular boss and human body skin recess, contact better as the lower lip lower portion, thereby reach the effect that shaves preferably.

The specific embodiment

The specific embodiment of the present utility model is described with reference to the accompanying drawings.

Embodiment one

With reference to Fig. 1, Fig. 2, a kind of guard of rotary single head electric shaver, comprise that a circular end face 1 and is by the downward cylinder 2 that extends of the periphery of this circle end face 1, with the axis by circular end face 1 center is central shaft, described circular end face 1 is provided with four first coaxial annular boss 31 from outside to inside from nearly peripheral position, second annular boss 32, the 3rd annular boss 33, Fourth Ring shape boss 34, described

annular boss

31,32,33, be respectively equipped with the radial pore 4 that advances on 34, and adjacent

annular boss

31,32,33, be respectively equipped with the annular groove 51 that is used to increase shaver guard intensity between 34,52,53.Described each

annular boss

31,32,33,34 is in the same plane.Form a fillet 23 between described first annular boss 31 and the described cylinder 2, and describedly advance pore 4 and extend to this fillet 23.

In rotary electric shaver, set of blades is matched with this guard below, and when shaving, skin is affixed on the guard, and the beard on the skin enters in the guard by advancing pore, is cut off by blade.The shape of this set of blades is made with effective working face of described guard suitable.

Embodiment two

With reference to Fig. 3, Fig. 4, present embodiment and the foregoing description one structure are basic identical, its main distinction is, described each

annular boss

61,62,63,64 edge are circular arc in the longitudinal section of radial direction separately, thereby can make

annular boss

61,62,63,64 and human body skin recess, contact better as the lower lip lower portion, thereby reach the effect that shaves preferably.

Embodiment three

With reference to Fig. 5, present embodiment and the foregoing description one, embodiment two structures are basic identical, and its main distinction is that described circular end face 1 is protruding sphere shape, can not only reach the effect that shaves preferably, and more attractive in appearance.

In addition, above-mentioned each guard is made by hard metal material, and advance the concrete shape of pore and do not limit, can be circle, rhombus etc.

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.
