Description

The electric razor tool tip device

[technical field]

The present invention relates to a kind of electric razor tool tip device, particularly a kind of oblique eccentric rotary and 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.Some shave less than beard more long, longer beard just more shave less than.So this type of shaver often needs to increase the temples cutter of a similar hair scissors to shave off long beard.

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.But it more is difficult to shave off to slightly long beard.Therefore it also usually needs a temples cutter to shave off long beard.

[summary of the invention]

The object of the present invention is to provide a kind of electric razor tool tip device of the eccentric rotary moving knife that tilts, overcome the various shortcomings of above-mentioned shaver.Because moving knife 2 is with moving knife 1 contact area in rotary course is relative not constant, so its noise is also lower.Because shaver moving knife 2 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 cutter.Its time rotational simultaneously, moving knife 2 and moving knife 1 automatic grinding not really keep 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 of the present invention not moving knife 2 upper surfaces 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 electric dual-purpose razor tool tip device.It has a base 4 when a shaver has a plurality of cutter head, and each base can be made of one.Moving knife seat 3 is housed on the base 4, and moving knife seat 3 is installed moving knife 2.Moving knife 1 is not fixed by base, also has spring 5 to be used for guaranteeing that moving knife 2 and moving knife 1 not be close to.Drive unit drives moving knife 2 rotations by moving knife seat 3.Since moving knife 2 axle center and moving knife seat 3 the running center off-centre of inclination is arranged, moving knife 2 and can not form a gap 6 between the moving knife 1, therefore when drive unit drives 3 rotation of moving knife seat, moving knife seat 3 drives moving knife 2 and rotates, and moving knife 2 rotates and and then rotation along with moving knife seat 3 with the space between the moving knife 16 not.This moment be in moving knife 2 and not the beard between the moving knife 1 will be shaved off.When moving knife 2 make rotation the time, between moving knife 2 and base 4, add a gear pair, the moving knife rotation is strengthened.The beard that breaks apart by chopping that its mode that shaves is original has become the form that is similar to sawed-off beard, and the effect that shaves like this can be better.Because moving knife 2 is eccentric rotaries, moving knife 2 and be not to have equaled numerous space 6 in fact between the moving knife 1, thereby its area that shaves is larger, better effects if shaves.Long beard also is to shave off than being easier to.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 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 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 contact area running of moving knife and moving knife not, so its noise is less; 4) moving knife and not moving knife processing request, material requirements is relatively so not strict, thereby cost is lower; 5) moving knife can directly be faced beard, therefore shaves cleaner; 6) thickness of moving knife is larger, therefore generally need not to change cutter head; 7) electric shaver of the present invention not the moving knife upper surface be 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:

Electric razor tool tip device of the present invention (actual use be usually to use two or more cutter heads) as shown in Figure 1.Comprise moving knife 2, not moving knife 1, base 4; The razor tool tip device also comprises moving knife seat 3 and spring 5.

Moving knife 2 and not moving knife 1 be close to sphere 21 and sphere 12, usually sphere 21 radiuses of moving knife 2 are slightly larger than the not radius of moving knife 1 sphere 12, are close to the not sphere 12 of moving knife 1 to guarantee moving knife 2 cutting edges.Moving knife 1 is not installed on the base 4, and the button bit 14 on the moving knife 1 is not buckled in plastic cement room 41 on the base 4, and plastic cement post 42 withstands the not below of moving knife on the base 4 simultaneously.Limit not each free degree of moving knife if the electric razor tool tip device adds a loam cake, can save button bit 14 on the moving knife 1 not and the room 41 on the base.

Moving knife 2 tilts to be assemblied on the moving knife seat 3, is assemblied in hole 31 on the moving knife seat 3 by the axle 23 on the moving knife 2, also can make by the hole 23 on the moving knife 2 to be assemblied on the moving knife seat 3 on the axle 31.Owing to tilting during hole 31 on the moving knife seat 3, thus also tilts after moving knife 2 assemblings, and the axle center of moving knife 2 and not on the moving knife 1 centre of sphere of sphere 12 crossing.So when moving knife seat 3 rotates, where no matter be in, can both guarantee that sphere 21 on the moving knife 2 is close to the sphere 12 on the moving knife 1 not.

The cylinder 32 of moving knife seat 3 is assemblied in the installing hole 43 on the base 4..Moving knife seat 3 drives rotation by Power Drive Unit by the polygonal hole 33 on the moving knife seat 3, drives the moving knife rotation in the time of 3 rotation of moving knife seat.

Compress Spring 5 be used for guaranteeing moving knife 2 and not moving knife 1 be close to, Compress Spring 5 can be assemblied on the position such as Fig. 1, also can be assemblied between moving knife 2 and the base 3, can also be assemblied between power input device and the base 3.

Fig. 3 (a) is the initial plane figure of one group of razor tool tip device, also is top view.Fig. 3 (b) is the plane after the initial position of one group of razor tool tip device rotates 180 degree, also is top view.Moving knife 2 an and space 6 is not arranged between the moving knife 1 as seen from the figure, space 6 are along with moving knife 2 rotations and rotate.Can not have aperture on the moving knife 1, when work time, space 6 is along with moving knife 2 rotates and rotates, be in space 6 and the aperture do not opened on the moving knife 1 in beard will be cut off.Because moving knife 2 is continuous operations, so that the quantity in space 6 in fact has is numerous, thereby reach the purpose that well shaves in work.

Not perforate 11 in the middle of the moving knife 1, the shape in hole can be circular, also can be polygon, other shapes such as quincunx, moving knife 1 does not have sphere 12 to contact with the human face, owing to being sphere, it upwards has outstanding, so more easily touch beard, shaving will be more convenient, clean.

Can find out from several accompanying drawings, the cutting edge that forms between the sphere 21 of moving knife 2 and the side 22 is circumferencial direction, and namely circumferencial direction has cutting edge, when moving knife 2 is made rotatable the time, if add a gear pair between moving knife 2 and the base 4; Perhaps add a disk and base 3 on the moving knife 2 and add an annulus, disk and annulus are tangent.Can strengthen the moving knife rotation like this, the cutting beard 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 that moving knife 2 revolution produce simultaneously.

Moving knife 2 is sphere-contact with moving knife 1 not, and contact area remains unchanged substantially, so noise is less.Because moving knife 2 twocoueses can rotate and shave, so the also corresponding meeting prolongation of cutter head life-span.Moving knife 2 is comparatively simple with the processing of moving knife 1 not, and material requirements so strict yet, so cost is lower.Moving knife 2 can be done thicklyer, thereby the life-span is longer.
