Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide an electric shaver that can be used effectively even by an inexperienced user by always keeping the cutting blade at an optimal angle with respect to the skin surface when using the electric shaver. The purpose is to

In a trimmer-type electric shaver that has a comb-shaped fixed blade and a movable blade, and the movable blade makes sliding contact with the fixed blade and moves back and forth, the skin surface 1 is
The fastest and shortest way to shave hair 13 is to press the cutting surface 12 of the razor 11 almost parallel to the surface of the razor. It often hits the skin surface 10 at right angles, and therefore has drawbacks such as not being able to shave quickly or shaving short.

The present invention aims to improve these drawbacks, and embodiments thereof will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of the electric shaver of the present invention, and FIG. 2 is a sectional view taken along the line A--A in FIG. 1 of the electric shaver with an attachment attached thereto. In these figures, 1 is the main body of the electric shaver, 2 is the main blade, and 3 is the sub-blade. 5 is pressed against the fixed blade 4 by a spring 6 inserted between the lower base 1' of the main body 1,
It is configured to be reciprocated in the direction of arrow B in FIG. 1 by a motor (not shown) and an eccentric cam housed in the main body 1, so that the cutting blade 7 cuts hair. Reference numeral 8 denotes a sheath-like attachment, which has a U-shaped curved attachment part 8a and is formed at one end of the attachment part 8a so that it can be fitted onto the outside of the main body 1 around the blade of the electric shaver and detachably attached. 1st
The guide part 8b extends approximately parallel to the cutting blade part 7 along the side surface of the cutting blade part 7 of the fixed blade 4 and the movable blade 5 with a gap therebetween, and is slightly in front of the cutting blade part 7. It consists of a second guide part 8c that protrudes from the first guide part 8b and a second guide part 8c that protrudes from the first guide part 8b. 8 is attached to the main body 1, the edge P of the first guide part 8b and the edge Q of the second guide part 8c of the attachment
It is assumed that the blade edges of the fixed blade and the movable blade are arranged in the vicinity of a straight line D connecting the two.

FIG. 3 shows an embodiment of the present invention in which the tip 9 of the second guide part 8c is comb-shaped, and as shown in FIG.
When shaving by moving the electric razor with the edge of c in contact with the skin surface 10, the comb-like part 9 straightens the hair, and the straightened hair is introduced between the fixed blade 4 and the movable blade 5. This allows the hair to be cut smoothly.

As described above, according to the electric shaver of the present invention,
Since the edge Q of the second guide part 8c projects forward from the cutting edge part 7, as shown in FIGS. 4 and 5, the edge Q of the second guide part and the first guide part Since the skin surface 10 is naturally pressed onto the line D connecting the edge P of the cutting edge 8b, there is no risk of using the cutting blade 7 directly against the skin surface, which makes it difficult to use. Even when used by a person, the fixed blade always comes into contact with the skin surface and keeps the cutting blade at the optimum angle, ensuring that hair is shaved accurately and in short lengths.
