Description

Novel net membrane type razor tool tip device

[technical field]

The present invention relates to a kind of Novel net membrane type razor tool tip device, particularly a kind of oblique eccentric rotary and nethike embrane formula razor tool tip device that can positive and negative rotation.

[background technology]

Electric shaver can be divided into two kinds of rotary, nethike embrane formulas by its work characteristics, all is that the single head shaver by the seventies develops.This type of electric razor tool tip processing mode very complex, some also has multi-layer cutter blade, and its difficulty of processing is quite large.And material requirements is very high, needs more valuable metal material, and durable not.Cutter head usually needs to change.Therefore its cost is also relatively high.The effect that shaves of this type of electric shaver is also more general, often can be with the plucking phenomenon.After the shaving of this type of shaver, the beard remaining lengths is also long, is difficult to the root of beard is shaved off, and shaves sordid sensation so have.

And rotary electric shaver is difficult to make and the more accessible sphere of people's face, thereby user's comfort level is relatively relatively poor.

Nethike embrane formula shaver adopts reciprocating type working method, and the effective area that shaves is relatively large, but its noise is very large and vibratory sensation is excessively strong, easily causes facial skin irritated.Its shaver be into calculate for accurate how much, reliable in durability and security.But its cost is also relatively high.Its blade becomes 90 degree with nethike embrane, sharpness is relatively poor.Effect is also relatively poor so it shaves, and its power needs larger, and reciprocating has also caused energy dissipation.Its residual quantity that shaves will be got well than rotary.

[summary of the invention]

The object of the present invention is to provide a kind of Novel net membrane type electric razor tool tip device of the eccentric rotary moving knife that tilts, overcome the various shortcomings of above-mentioned shaver.Because moving knife 3 is relative constant with nethike embrane 2 contact area in rotary course, so its noise is also lower.Because shaver moving knife 3 of the present invention can be made can rotation, thereby shaves and feel sharper, resemble daily we cut the dish, more laborsaving with feeling to cut the dish during stretching before and after the kitchen knife.Simultaneously, its time rotational, the moving knife automatic grinding really keeps the sharpness of moving knife.Part processing request of the present invention is relatively low, and material requirements does not have other shavers so high yet, and the moving knife Thickness Ratio is larger, so its working life is also long.Electric shaver nethike embrane 2 of the present invention is dome shape, thereby more easily touches beard, and it is more comfortable that the sphere-contact user also can feel.Razor head of the present invention has outstanding cleanliness, comfort level, convenience and the outstanding cost performance of scraping.

Purpose of the present invention realizes by following means: a kind of Novel net membrane type razor tool tip device.It has a base 4, loam cake 1, side cover 6, nethike embrane 2, moving knife seat 5, at least one moving knife 3.Assembling moving knife seat 5 on the base 4, moving knife seat 5 is installed moving knife 3.Nethike embrane 2 is fixing together by loam cake 1, side cover 6, base 4.Because moving knife 3 has the off-centre of inclination with the running center of moving knife seat 5, therefore when drive unit drives 5 rotation of moving knife seat, has certain position movement between moving knife 3 and the nethike embrane 2.The beard that be between moving knife 3 and the nethike embrane 2 this moment will be shaved off.When moving knife 3 make rotation the time, between moving knife and base, add and add disk between a gear pair or moving knife 3 and the base 4 and contact increasing friction force, strengthen the moving knife rotation.The beard that breaks apart by chopping that its mode that shaves is original has become approximate sawed-off beard, and the effect that shaves like this can be better.Because moving knife is the inclination eccentric rotary.The effect that shaves of razor tool tip device positive and negative rotation of the present invention is the same fully.

The invention has the advantages that: 1) because moving knife 3 is can positive and negative rotation, thereby cutter head prolongs service life relatively, and sharpness can keep more for a long time; 2) because moving knife 3 also can be made rotation, the beard that breaks apart by chopping of common shaver is become approximate sawed-off beard, its better effects if that shaves; 3) substantially be consistent in the running of the contact area of moving knife 3 and nethike embrane 2, so its noise is less; 4) moving knife 3 processing requests, material requirements are relatively so strict thereby cost is lower; 5) thickness of moving knife 3 is larger, therefore generally need not to change cutter head; 6) electric shaver nethike embrane 2 of the present invention is dome shape, the zone of shaving be project upwards thereby more easily touch beard, it is more comfortable that the sphere-contact user also can feel.

[specific embodiment]

For example the present invention is described in detail below in conjunction with accompanying drawing:

The cutaway view of Novel net membrane type razor tool tip device of the present invention as shown in Figure 1 comprises a base 4, loam cake 1, side cover 6, nethike embrane 2, moving knife seat 5 and at least one moving knife 3.

Moving knife 3 and nethike embrane 2 are close to sphere 31 and sphere 21, and sphere 31 radiuses of moving knife 3 are slightly larger than the radius of nethike embrane 2 spheres 21 usually, are close to the sphere 21 of nethike embrane 2 to guarantee moving knife 3 cutting edges.Nethike embrane 2 is installed on the base 4, is pushed down by the flange 11 of loam cake 1 in the middle of the top, and the periphery, top is pushed down by side cover 6.Withstood by base 4 intermediate flange 45 in the middle of nethike embrane 2 belows, periphery, nethike embrane 2 below is withstood by base 4 annulus 41.Nethike embrane 2 between this moment base 4 annulus 41 and the intermediate flange 45 is stressed and be bent downwardly and be close to the sphere 31 of moving knife 3.When moving knife seat 5 drove moving knife 3 rotation, the beard that enters the aperture 22 on the nethike embrane 2 will be shaved off.

Moving knife 3 tilts to be assemblied on the moving knife seat 5, is assemblied in hole 53 on the moving knife seat 5 by the axle 33 on the moving knife 3, also can make by the hole 33 on the moving knife 3 to be assemblied on the moving knife seat 5 on the axle 53.Because hole or axle 53 tilt on the moving knife seat 5, thus also tilt after moving knife 3 assemblings, and the centre of sphere of sphere 21 intersects on the axle center of moving knife 3 and the nethike embrane 2.So when moving knife seat 5 rotates, where no matter be in, can both guarantee that sphere 31 on the moving knife 3 is close to the sphere 21 on the nethike embrane 2.

The cylinder 52 of moving knife seat 5 is assemblied in the installing hole 44 on the base 4..Moving knife seat 5 is driven by the profile of tooth 51 on the moving knife seat 5 by Power Drive Unit and rotates, and cuts off beards thereby drive moving knife 3 rotations when moving knife seat 5 rotates.

Fig. 3 is the front view of Novel net membrane type razor tool tip device of the present invention.Nethike embrane 2 contacts with the human face with sphere, owing to being sphere, it upwards has outstanding, so more easily touch beard, shaving will be more convenient, clean.

Can find out when moving knife 3 from several accompanying drawings and to make rotatable the time, if add a gear pair between moving knife 3 and the base 4; Add on the moving knife 3 perhaps that a disk and base 4 add an annulus disk and annulus is tangent.Can strengthen the moving knife rotation like this, cutting has just become approximate sawed-off beard, thereby its better effects if that shaves.Gear pair or disk annulus can also bear the centrifugal force of the revolution generation of moving knife 3 simultaneously.

Moving knife 3 is sphere-contacts with nethike embrane 2, and contact area remains unchanged substantially, so noise is less.Because moving knife 3 twocoueses can rotate and shave, so the also corresponding meeting prolongation of cutter head life-span.The processing of moving knife 3 is comparatively simple, and material requirements does not have so strict yet, so cost is lower.Moving knife 3 can be done thicklyer, thereby the life-span is longer.
