The specific embodiment

As shown in Figure 1 and Figure 4, one preferred embodiment of a kind of shaver 100 of the present utility model, it is an electric shaver, but should be noted that, because the utility model improves the position at cutter head structure, therefore the utility model technology can be used for the shaver under other type of drive equally, and is for example manual.

In this preferred embodiment, described shaver 100 comprises a motor 1, a transmission mechanism 2, at least one interior cutter 4 and at least one outer cutter 5, and a cutter head shell 6; This cutter head shell 6 is used to install described outer cutter 5; at least one the installing hole portion 61 that has corresponding outer cutter number on it; described outer cutter 5 can inner and outer movable in described installing hole portion 61; concrete but be not limited to; the number of the portion of installing hole described in the present embodiment 61 is three, that is what adopt in the present embodiment is corresponding three the interior cuttves of three outer cuttves, and it is in triangular distribution; as shown in Figure 4, be interpreted as restriction to scope of patent protection of the present utility model after the installation but can not therefore be about to this number.

Described transmission mechanism 2 of the present utility model is a gear train, wherein comprise a driving gear 21 and three driven gears 22 of corresponding three interior cuttves at least, described motor 1 drives described driving gear 21, the interior cutter 4 coaxial rotations that described driven gear 22 is corresponding with it, wherein, cutter 4 has the U type edge of a knife in described, as shown in Figure 3, each of described U type edge of a knife end end is the edge of a knife with ladder, circle distribution is carried out in the axle center of this U type edge of a knife cutter in described, and has a slightly outward-dipping offset angle, and this offset angle is meant the U type edge of a knife and angle radially, operated by rotary motion is between 0～100 degree, be preferably 75 degree, like this, will oblique cutting during beard in cutting, stock-removing efficiency is higher, and can not form the situation that the pain user is not pulled in cutting down.In addition, described interior cutter 4 and all integrated parts of described outer cutter 5 can reduce assemble flow and operating time.

Each outer cutter 5 of the present utility model has inside and outside two exception cuttves 51 and 52, as shown in Figure 2, form inside and outside two all endless belt, thereby the radius cross sectional shape is

These two projections are two all endless belt, these two tracks that all endless belt inside is rectangle as two cross sections, make described in two of each U type edge of a knife ends of cutter respectively along rotary cutting in this two all endless belt inwall, like this, the cutting position of cutter is two Zhi Duan of each U type edge of a knife in described, and being not limited to the end, end sides also can be cut; Be inner protuberance in the middle of the cutter outside these both sides of described outer cutter, form an inner projection chow ring, this projection chow ring can be strengthened the support strength of described outer cutter 5, the blind end of the U type edge of a knife of described interior cutter 4 on this projection chow ring in described the axle center of cutter 4 rotate.Every exception cutter (being on all endless belt) all has some mesh portions that beard stretches into that are used for simultaneously, it in this preferred embodiment circumferential a plurality of short slit 511, this weak point slit 511 with radially can have a predetermined angle, operated by rotary motion is between 0～90 degree, be preferably 25 degree, like this, make things convenient for stretching into of beard, and being cut the hair that gets off can throw away under centrifugal action, and can not accumulate in the shaver loom.Simultaneously, this short slit periphery so just can allow hair have the more large-area district of setting out along 512 darker.Certainly the utility model product also can adopt other forms of mesh portion, if its adopt of the present utility model above-mentioned in the fit shapes of cutter and outer cutter, should belong to scope of patent protection of the present utility model equally.

In the shaver 100 of the present utility model, described in each cutter 4 bottoms also be provided with an elastic supporting member for supporting optical member 8, it is a cylindrical shell, its top is coaxial affixed with the lower end of described interior cutter 4, can adopt particularly, the top is set to a flat portion of connecing of refuting, and is inserted in corresponding interior cutter bottom adaptedly and refutes and connect in the recess (scheming not shown), be fixed on the described driven gear 22 and its bottom is coaxial, be provided with one first elastic component (figure is for illustrating) in this cylindrical shell.Have an installation ring portion 221 to upper process on the described driven gear 22, this installation ring portion 221 is provided with a plurality of installation bayonet sockets 222; And, the cylindrical shell bottom of described elastic supporting member for supporting optical member 8 has a plurality of installation teats 822, can with described a plurality of installation bayonet socket 222 clampings, and has a range of moving, so described first elastic component is limited in the described cylindrical shell, in described between cutter 4 and the driven gear 22, thereby described interior cutter 4 can each other can resilient movement with described driven gear 22.Simultaneously, described shaver also comprises a sealing plate 3, support has cutter installing plate 7 on it, all corresponding described interior cutter 4 is provided with three hole portions on this interior cutter installing plate 7 and the sealing plate 3, cutter installing plate center is provided with a hole portion in described, one supports column piece passes this hole portion, the top is resisted against on the described cutter head shell, this support column piece bottom then is resisted against in the recess of described sealing plate central authorities, one second elastic component is set on this support column piece, two ends be resisted against respectively described sealing plate and described between the cutter installing plate, be used for the position relation of flexible adjustment between it.Like this, outside described cutter 5 when different angles contact skin, described elastic supporting member for supporting optical member can adjust described in cutter and outer cutter applying skin, thereby it is more thorough to shave.

Should be understood that; foregoing description only is the detailed description of the utility model preferred embodiment; can not be interpreted as restriction to claim of the present utility model; for those of ordinary skills; can be according to the technical solution of the utility model change or replacement; and all these changes or replacement all should belong to the protection domain of the utility model appended claim.
