Description

[Detailed description of the invention] This invention relates to an outer razor blade that uses electricity as a driving source, and its purpose is to shave hair short without irritating the skin, and to remove hair. The purpose of the introduction is to provide a good razor blade.

As shown in FIGS. 6 and 7, the outer blade of a conventional razor has a protrusion 2 formed in the middle part of the outer surface of the outer cutter that forms the longitudinal direction of the elongated hair introduction hole. At the same time, the inner cutter E is in sliding contact with the inner surface of the outer cutter A, and when the skin is brought into contact with the outer surface of the outer cutter A, the amount of skin that protrudes from the hair introduction hole to the inner surface of the outer cutter A is reduced by the amount of hair. There is a problem in that the length and width directions of the introduction hole are uneven, making it impossible to shave short hair that grows in areas with little protrusion of the skin. However, if the size of the beard is increased overall, there is a problem in that it may cause irritation to the skin when shaving.

The present invention has been devised in view of the above-mentioned problems, and will be described below with reference to the drawings showing embodiments of the present invention.

In FIGS. 1 to 4, an outer cutter 1 is formed into a dome shape and is attached to an outer cutter base 2. As shown in FIGS.

A large number of hair introduction holes 3 are bored in the outer blade 1, and a pair of small holes (4 normal hair introduction holes with a bite diameter of about 0.5 mm) are inserted into the J4L.
They are configured to communicate with each other through a large hole 5 that is formed to be wider than 4.

The hair introduction hole 3 is formed by an outer cutter crosspiece 6, and a protrusion 7 having the same height is formed on the outer surface of the outer cutter crosspiece 6 forming the large hole 5 over the entire length up to the boundary between the large hole 5 and the small hole 4. has been done.

The inner cutter 8 is in sliding contact with the inner surface of the outer cutter 1.

Next, the operating state will be explained with reference to FIG. The amount of skin a that protrudes to the side is approximately equal in the large hole 5 and 1JfL 4, and since the inner blade 8 and the skin a maintain an appropriate distance, the skin a is not damaged by the inner blade 8 and long hairs can be smoothly removed. It is then introduced into the large hole 5 and the small hole 4 and cut by the inner cutter 8.

As described above, the razor blade according to the present invention has a large hole with a large diameter and a small hole with a smaller diameter than the large hole communicating with each other to form the hair introduction hole, and the outer cutter crosspiece forming the large hole. Since the outer surface is formed with protrusions of the same height over the entire length up to the boundary between the large and small foramen, the skin that attempts to invaginate the large foramen is pushed up by the protrusions. Similar to the skin that protrudes to the inner surface of the outer blade, the skin is kept at a distance from the inner blade and is not damaged by the inner blade VC, so the hair introduction hole can be made larger than the normal hair introduction hole, making it easier to accommodate long hair. It has the effect of improving the introduction and allowing the hair to be shaved short without irritating the skin, and the protrusions pull and press the skin, raising the hair, and reducing the difference between the large foramen and J4L. Since the hair can be introduced into the large hole and the small hole by pulling or pulling the hair with the protrusion of the part, there is an effect that the hair can be cut into short pieces.
