Description

[Detailed description of the invention] This invention relates to a razor blade for slitting eyebrows, etc.

A conventional reciprocating trimmer type razor blade for shaping eyebrows is shown in FIGS. 1 and 2.

That is, in the case of the one shown in FIG. 1, the blade width r of the cutting edge Q at the leading edge in the blade alignment direction of the fixed blade P is wider than the other blade widths S;
Because the groove width t of the blade cutting groove U at the cutting edge is narrow, it is difficult to see the eyebrow line and it is difficult to smoothly introduce only the hairs that protrude from the line, resulting in the eyebrow shape not being neatly aligned. , and the fixed blade P' in Fig. 2 is
The blade width r' of the cutting edge Q' at the cutting edge is narrower than that in Figure 1, so the line around the eyebrows is relatively easy to see and the shape of the eyebrows is neatly aligned. All of them have the disadvantage of being easily damaged, making them unsuitable for shaping eyebrows smoothly and safely.

Therefore, the purpose of this invention is to provide a razor blade for shaving that allows smooth and safe shaving during eyebrow shaping and the like.

An electric shaver to which an embodiment of this invention is applied is shown in FIGS. 3 to 5.

In other words, this electric shaver has a battery, motor,
Main body housing 1 with built-in rotation and reciprocating motion conversion mechanism;
It consists of a lower cover 2, a blade holder 3, and a switch 4, and the blade holder 3 is provided with a razor blade 5 for cutting.

N is a razor blade for armpit hair.

As shown in FIGS. 4 and 5, this razor blade 5 has a cutting edge groove 8a at the most extreme part of the cutting groove 8 in the blade part 7 of the fixed blade 6 in the blade arrangement direction. groove width b1 to another groove width b
2, and the positional relationship of the cutting edge part 10 of the movable blade 9 is such that in the reciprocating movement range of the movable blade 9, the end-to-end distance l1 in the reciprocating direction with respect to the most advanced cutting edge part 11 of the fixed blade 6
, the distance between the edges in the direction of the cutting edge l2 is l 1 > 0, l 2
>O, and the blade cutting groove 8a has a sufficient operating range C (greater than the thickness of the hair) to cut the hair by the movable blade 9 when hair is introduced into the groove. There is.

FIG. 6 shows the shaped state of eyebrows A.

That is, the user turns on the switch and moves the tip of the cutting edge portion 11 of the fixed blade 6 along the line B of the eyebrow line to introduce unnecessary hair around the eyebrow line into the cutting groove 8a.

With this structure, the unnecessary hair around the eyebrows can be smoothly introduced into the blade cutting groove 8a and shaved, and the blade width of the cutting edge part 11 at the leading edge can be made wider to remove the hair around the eyebrows. Even if the hair is hidden, unnecessary hair protruding from the eyebrows can be smoothly introduced into the blade cutting groove 8a and shaved, safety can be ensured, and the shape of the eyebrows can be neatly finished as desired.

As mentioned above, the razor blade for edge cutting of this invention has a groove width of the cutting groove at the end of the fixed blade that is larger than the other grooves,
It has the effect of allowing the eyebrows to be shaved smoothly and safely.
