Description

[Detailed Description of the Invention] The present invention relates to an electric shaver blade head, and its purpose is to provide an electric shaver blade head that can shave hair in a short time.

As shown in FIG. 8, an outer cutter A is provided with a hair introduction hole A, and a comb is provided at the outermost edge of the outer cutter A and has a comb groove C corresponding to the hair introduction hole B of the outer cutter A. A blade head for an electric shaver has been proposed, but as shown in Figure 9, the hair a that falls in the direction of moving the blade head is not introduced into the hair introduction hole even if it enters the comb groove. Also, the hair a that has fallen toward the blade head hits the entrance of the comb groove and is raised in an arched manner, but if it does not slide over the bottom of the comb groove, it will not reach the comb groove. The disadvantage is that the hair is pushed down at the entrance and cannot be introduced into the hair introduction hole, so it takes time to shave the hair.

The present invention has been devised in view of the above drawbacks, and will be described below with reference to the drawings showing embodiments of the present invention. In FIGS. 1 and 2, the outer cutter 1 is formed by curving a thin metal plate into a dome shape, and a small hair introduction hole 3 is provided in the center of the ceiling 2.
However, radially long slit-shaped hair introduction holes 4 are bored in the outer circumferential part of the ceiling part 2, and hair introduction holes 5 continuous from the ceiling part 2 are made in the upper part of the peripheral wall hanging from the ceiling part 2. ing. The lower end edge of the peripheral wall of the outer cutter 1 is fixed to an outer cutter base 7 which is detachably attached to the main body case by a threaded portion 6. Inner blade 8
consists of an inner blade 9, an inner blade base 10 that holds the inner blade 9, and a push-up spring 11 that pushes up the inner blade 9, and is attached to a motor (not shown) in the main body case. The inner cutter 8 slides on the inner surface of the outer cutter 1 and rotates when driven by the motor. The hair introduction comb 12 has a protruding rib-shaped first comb 13 spaced apart from the upper end surface of the cylindrical body, and a second comb 14 that is rotatable in directions toward and away from the first comb 13. The first comb 13 is placed on the outer edge of the first comb 13 to face the first comb 13.
It is elastically formed integrally with. first comb 1
A comb groove 15 facing the hair introduction hole 5 of the outer blade 1 is formed between the second combs 14 and 13 and between the second combs 14 and 14, and the hair is introduced so that the hair introduction hole 5 and the comb groove 15 match. The comb 12 is inserted into the outermost edge of the outer cutter 1, which is the outer periphery of the peripheral wall of the outer cutter 1. A bulge 16 is formed at the tip of the second comb 14 in consideration of ease of scooping the hair and contact with the skin. Second
A constricted portion 17 is formed on the outer wall of the comb 14 so that the second comb 14 can easily approach and separate from the first comb 13. The blade head A is composed of an outer cutter 1, an inner cutter 8, and a hair introduction comb 12.

Next, the operating state will be explained with reference to FIGS. 3 to 6. When shaving fallen hair in the direction of the arrow X, which is the direction in which the blade head A is moved, the second comb 14 is separated from the first comb 13 at the initial stage of introduction shown in FIG. 13
and the second comb 14 is stretched;
Hair a is lying in its natural state. Next, when the blade head A is moved in the X direction, the second comb 14 rotates due to elastic deformation due to the frictional force with the skin and approaches the first comb 13, as shown in FIG. The skin between the comb 13 and the second comb 14 is loosened and the hair a is forcibly pushed toward the hair introduction hole 5 side of the outer blade 1, and the hair a is styled with the first comb 13 and the hair a is removed. It is introduced into the introduction hole 5 and cut with the inner cutter 8. When shaving hair a that has fallen to the side of the blade head A, use the fifth
As shown in the figure, at the initial stage of introduction, the hair a gets caught at the entrance of the comb groove 15 and is bent into an arched shape.
When the blade head A is moved in the X direction, the second comb 14
As shown in FIG. 6, due to the frictional force with the skin, the combs rotate due to elastic deformation and approach the first comb 13, causing the skin between the first comb 13 and the second comb 14 to become loose, and the hair to be removed. The hair a is forcibly pushed toward the hair introduction hole 5 side of the outer blade 1 and the hair a is styled by the first comb 13, and the hair a is introduced into the hair introduction hole 5 and cut by the inner blade 8.

FIG. 7 shows another embodiment of the hair introduction comb, in which the second comb 14 is connected to the first comb 13 via a hinge.
The second
The hinge is biased by a spring in the direction in which the first comb 14 moves away from the first comb 13.

Although the example is a rotary electric shaver,
It may also be a reciprocating electric shaver.

As described above, the electric shaver blade head according to the present invention includes an outer cutter having a hair introduction hole, and a first comb groove located at the outermost edge of the outer cutter and having a comb groove corresponding to the hair introduction hole of the outer cutter. An electric shaver blade head comprising a comb and a second comb connected to the first comb at the outer edge of the first comb, the direction in which the second comb approaches and separates from the first comb. Since the comb is characterized by being freely rotatable, when the second comb approaches the first comb due to friction with the skin, the skin is removed between the first comb and the second comb. Since the loose hair is forcibly pushed toward the hair introduction hole of the outer blade, the hair can be easily introduced into the hair introduction hole and can be shaved in a short time.
