The frontal surface of the existing common shaver is smaller than the upper beard-feeding hole 121, and at a specific rotation moment, the frontal surface of the shaver falls into the projection of the reference direction of the shaving hole, so that the phenomenon of beard tearing is easy to occur when the beard-feeding position is deviated. In the present embodiment, since there is the second shaving blade 348 which does not overlap with the projection of the reference direction of the upper beard holes 121 of the outer ring blade network 12 at any moment of rotation, the shaving area can be increased, and particularly, a beard entering effect is better for a beard whose beard entering direction is inclined so as to be inclined out of the vertical projection position of the upper beard holes 121 of the outer ring blade network 12.
Further, the second shaving blade 348 may be only at one radial end of the first shaving blade 347, or may be bifurcated at both radial ends of the first shaving blade 347. The radial direction refers to a centrifugal force direction and a centripetal force direction when the outer fixed beam 33 rotates.
Similarly, the first forward blade 242, the third forward blade 345, the first reverse blade 243, the second reverse blade 343, and the third reverse blade 346 may be arranged as above, the first forward blade 242 and the first reverse blade 243 correspond to the beard inlet of the inner ring blade net 11, and the third forward blade 345 and the third reverse blade 346 correspond to the side beard inlet of the outer ring blade net 12.
In addition, the inner shaving unit 2 and the outer shaving unit 3 of the present embodiment are each obtained by drawing, stamping, electro-chemical etching, surface passivation, blade grinding, etc., a metal workpiece.
In addition, the blade angles of the first forward blade 242, the second forward blade 342, the third forward blade 345, the first reverse blade 243, the second reverse blade 343 and the third reverse blade 346 are acute angles.
In addition, in the embodiment, the first forward blade 242, the second forward blade 342, the third forward blade 345, the first reverse blade 243, the second reverse blade 343, and the third reverse blade 346 are simultaneously attached to the blade net, and are automatically ground and attached, and are automatically compensated after being worn.
In addition, as a modification of this embodiment, a plurality of rings of middle ring cutter meshes may be further included between the outer ring cutter mesh 11 and the inner ring cutter mesh 12, and correspondingly, the cutter head assembly further includes a middle cutting assembly covered by the middle ring cutter meshes.
