The specific embodiment

With reference to Fig. 1 and Fig. 2, shaver blade unit of the present utility model comprises: outer framework 1, lubricious strip 3, protector 5, at least one elongate blades 7.Particularly, described lubricious strip 3 is positioned at the top of described outer framework 1; Described protector 5 is positioned at the bottom of described outer framework 1; Described blade 7 is bearing between described protector 5 and the described lubricious strip 3 by described outer framework.

Particularly, as shown in Figure 2, three elongate blades that are parallel to each other 7 are housed in the outer framework 1, each blade has perpendicular to the shaver blade 6 that direction X extends that shaves, as shown in Figures 1 and 2, three parallel blades 7 are positioned between the left frame wall and right frame wall of outer framework 1 movable dismounting and installation.On left frame wall and right frame wall, a pair of spacing ring 12 is set also, uses so that be installed on the interior more firm safety of blade of outer framework.Described lubricious strip 3 is arranged at the top of outer framework 1, when being used for shaving and carrying out skin is lubricated, improve the skin comfort level, generally, degree of lubrication during for the increasing shaving, actual shaving aid such as skin lubrication oil or the skin varniss of comprising in lubricious strip surface, these paint possess hydrophilic properties, can secrete the material that some help shaving behind the contact water, make shaving lubricated more comfortable.Described protector 5 is made by elastomeric material, is fixed in outer framework 1 bottom, and its fixed form can be bonding, and protector bottom and plasticity that elastomeric material is made have chemical affinity between the framework outward, are easy to bonding; Integrally formed in the time of also can be with it for framework outside making.Protector is used at first contacting skin, stretching of skin when shaving begins.Described lubricious strip 3 and protector 5 all with the direction X approximate vertical that shaves of shaver.

With reference to figure 3, described protector 5 has a bottom 11, and the fin 21 of multirow almost parallel is set on the described bottom 11, and each fin extends upward and form a plurality of most significant ends 15 from described bottom, and described these most significant ends 15 are arranged in a cambered surface that projects upwards.Particularly, described bottom 11 has radial surface 23, and described fin 21 extends upward from radial surface 23, its bearing of trend and the direction X approximate vertical that shaves.Described multirow fin is provided with closely-spaced each other, and these have radian at interval on radial surface 23, makes described surface present outwards outstanding arc.
