Description

[Detailed Description of the Invention] The present invention relates to a hair clipper-type electric shaver equipped with a fixed blade having a comb-shaped blade portion and a movable blade, in which a comb is provided in front of the cutting edge of the fixed blade.

Conventionally, this type of electric razor with a comb uses a comb to stretch the skin and improve the hair, as well as to straighten the hair.
In addition, it is designed to prevent cuts caused by contact between the blade edge and the skin, making it soft against the skin, and providing a pleasant warping feeling.In particular, those using a roller comb are designed to have an even softer feel against the skin. Can be done.

By the way, when looking at conventional combs, the main focus is on making the blade part soft against the skin, and the ability to introduce hair in the relationship between the comb and the blade part is not addressed, and for this reason, the comb does not allow hair to be introduced into the skin. This method has disadvantages such as non-uniform introduction of shavings into the blade, resulting in unshaved areas.

Furthermore, when shearing relatively soft skin, the skin becomes loose and the comb is not fully effective, resulting in unshaved areas and the skin coming into contact with the tip of the movable blade, resulting in rough skin.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide an electric shaver that can eliminate the above-mentioned drawbacks, has a simple structure, and is easy to clean.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 6.

In the figure, reference numeral 1 denotes a housing having an open top surface, and is equipped with a drive section 2 made of an electric motor or the like inside, and a movable blade 3 driven by the drive section 2 is disposed in the opening.

Reference numeral 4 denotes a cover for skin contact that is removably attached to the opening of the housing 1, and a comb-shaped fixed blade 5 is integrally attached to the back side.

The fixed blade 5 has a blade section 5a for shaving armpit hair etc. located at the front end of the cover 4, and an auxiliary blade section 5b for shaving eyebrows etc. at the rear end of the cover 4. 5
a and 5 b are brought into sliding contact with the blade portions 3 a and 3 b of the movable blade 3, respectively.

A comb 6 is provided in front of the blade portion 5a of the fixed blade 5.

This comb 6 is configured in the shape of a rotating roller, and has a large number of annular guide grooves 7 on its outer periphery, and the uneven pitch P1 of the guide grooves 7 is made to match the uneven pitch P2 of the blade portion 5a of the fixed blade 5. .

Then, the guide groove 7 of this comb 6 is made to face the fixed blade 5a, and the convex part 8 of the comb 6 is made to match the concave part 9 of the opposing fixed blade 5 (see FIG. 6), and both ends of this comb 6 are , l protrudes integrally from the cover 4 to both sides of the fixed blade.
It is rotatably supported by a pair of brackets 10.

In other words, the guide groove 7 of the comb 6 is the bracket of the cover 4)
10, the distance and height arrangement relative to the fixed blade 5 are defined.

The cover 4 is integrally made of an elastic material, and the comb 6 is installed by inserting both ends of the comb 6 with the brackets 10 of the cover 4 slightly spread left and right, and then using the elastic material of the bracket l-10. (See Figure 4).

In addition, a pair of protrusions 11 are provided on the surface of the cover 4 at the blade portion 5a.
They are integrally protruded along the traveling direction a in an eight-shaped arrangement with narrow intervals on the traveling direction side.

Therefore, when shaving glandular hair, for example, the protrusions 11 on the surface of the cover 4 should be aligned with the skin, and the comb 6 should be moved forward (in the direction a) so as to lightly touch the comb 6.

Then, the outer edge of the protrusion 11 comes into contact with the skin, causing the front (a)
The comb 6 moves smoothly by rolling the skin, and the hair 12 is separated by each convex part 8 of the comb 6, and the hair 12 is separated and arranged. introduced into the recess 9 of the blade part 5a,
The heavy shaving action progresses in sequence (see Figures 5 and 6).

With this configuration, since the comb 6 provided in front of the blade portion 5a of the comb-shaped fixed blade is a rotating roller, it rolls into contact with the skin and has good sliding. Since the rotating roller is provided with guide grooves 7 that match the pitch of the concave and convex portions of the blade portion 5a, the bristles 12 are evenly removed in accordance with the number of concave portions 9 of the blade portion 5a of the fixed blade. As a result, the hair 12 is evenly introduced into the recess 9 of the blade portion 5a of the fixed blade, and there is no unshave as in the conventional case.

Therefore, you can shave smoothly and there is no unshaved area.
The condition in which the skin comes into contact with the barbs 5a becomes uniform, and when shaving areas where the skin is soft, such as the armpits, it is possible to prevent snags and cuts and shave well, making it effective as a razor for women, etc. can be used for

The comb 6 can be made by rotating a rotating shaft as in the above embodiment, or by a roller comb in which a shaft is inserted through a large number of pieces so that the pieces themselves rotate without being displaced in the axial direction. can do.

Further, in the above embodiment, the convex portion of one of the opposing comb 6 and the blade portion 5a of the fixed blade was made to match the concave portion of the other side.
For example, as shown in FIG. 7, the convex portions 8, 13 and concave portions 9, 14 of the comb 6 and the blade portion 5a may be opposed to each other.

Even in this case, the unevenness pitch P1 of the comb 6 and the blade portion 5a. By matching P2, the comb 6 is a rotating roller and the bristles 12 are aligned with the recess 9 of the blade portion 5a.
This ensures that the shaver is properly introduced into the shaver, resulting in a good shave.

The present invention described above has the following effects because it has the structure described in the claims of the above-mentioned utility model registration.

Since the fixed blade and the comb are each supported by the skin contact cover, these can be positioned by the skin contact cover, and the relative positional relationship between the two can be set with high accuracy without variation due to assembly errors, etc. Can be done.

At the same time, the comb consists of a rotating roller, and the guide grooves of the comb match the pitches of the unevenness on the blade of the fixed blade, so that the comb can sweep the hair according to the number of pitches of the unevenness on the blade of the fixed blade. It can be done evenly.

In other words, for these reasons, the ease of introducing hair is improved,
Prevents shaving.

Since it is equipped with a skin contact cover and the comb supported by this is formed into a rotating roller, it has good contact with the skin even on soft skin areas such as the armpits, and prevents the blade from getting caught on sensitive skin. It can prevent rough skin caused by cuts, etc.

Furthermore, the cover for skin contact is made of an elastic material, and a pair of brackets integrally protrudes from the cover, and these brackets are elastically deformed to sandwich both shaft ends of the comb, so that the comb can be freely rotated as a cover. Since the comb is supported, the number of parts required for supporting the comb to the cover is small, and the structure is simple.

Moreover, the skin cover that supports the comb and fixed blades is removable from the housing provided with the movable blades, and the comb can be removed from the cover by elastically deforming the pair of brackets as necessary. Therefore, these can be disassembled and the skin cover, fixed blade, comb, and movable blade can be cleaned individually, making it easy to clean.
