DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an electric shaver equipped with a hair introduction comb.

[Background technology]

Conventionally, this type of rotary electric shaver uses a hair introduction comb to straighten loose hair (long hair) and curly hair and introduce it into the hair introduction hole of the fixed blade, that is, the outer blade, as shown in Figure 1. It's summery. Reference numeral 1 indicates an outer cutter with a cylindrical peripheral wall 10 hanging downward from the outer peripheral edge of the dome-shaped upper surface 9, and reference numeral 2 indicates an inner cutter.The outer cutter 1 is attached to the outer cutter frame 3, and the inner cutter 2 is attached to the inner cutter frame. 4
installed on. The outer cutter frame 3 is detachably attached to the main body housing (not shown) using a threaded cylindrical portion 5, and the inner cutter frame 4 is attached to the output shaft 7 of a motor (not shown) in the main body housing. When driven, the inner cutter 2 rotates while slidingly contacting the inner peripheral surface of the outer cutter 1. A small hair introduction hole 12 is provided in the center of the upper surface 9 of the outer blade 1, and a three-dimensional slit-shaped hair introduction hole 13 that is continuous with the outer peripheral edge of the upper surface 9 is provided in the upper part of the peripheral wall 10 in the horizontal direction. A large number of annular holes are formed, and the hair introduction holes 13 are long in the radial direction and arranged in radial rows. 15 is a hair introduction comb;
The hair introduction comb 15 has a protruding rib 17 protruding from its upper end surface to form a hair introduction groove 18 corresponding to the hair introduction hole 13. As shown in FIG.
The outer cutter 1 is connected so that the hair introduction hole 13 of the outer cutter 1 is in communication with the outer cutter 1.
It is attached to the outer periphery of the peripheral wall 10 of. By the way, in such an electric shaver, as shown in FIG. 7, hair is introduced into the hair introduction holes 13 of the outer blade 1 while being styled by pressing the hair introduction comb 15 against the skin S, and then cut with the inner blade 2. In this case, the shape of the hair introduction comb 15 and the hair introduction hole 13 of the outer blade 1 or the shape of the hair introduction comb 1
If the relative position between 5 and the outer cutter 1 is not appropriate, the inner cutter 2
This may cause the skin to become irritated and become irritated.
It may feel uncomfortable on the skin. That is, the main factors that influence the stimulation are the slit width B ₁ of the hair introduction hole 13 and the blade thickness T in the outer blade 1, and the hair introduction groove 18 in the hair introduction comb 15.
The groove width b ₁ and the length of the protruding rib 17 in the hair introduction groove direction, that is, the radial dimension W, and the relative position between the hair introduction comb 15 and the outer cutter 1 is determined by the height difference, that is, the step (△H), and the hair introduction comb 17. This is the lateral deviation (ΔB) between the introduction hole 13 and the hair introduction groove 18. In addition, the factors involved in contact with the skin are the corners R ₁ and R ₂ of the protruding rib 17, the level difference (△H) between the hair introduction comb 15 and the outer blade 1, and the protruding rib 17.
is the inclination angle θ of the upper end surface. However, in the conventional hair introduction comb 15, it was not possible to adjust the factors that affect stimulation and the factors that affect skin contact.
As shown in the figure, the amount of protrusion δ of the outer cutter 1 of the skin S into the hair introduction hole 13 becomes larger than necessary, and the skin S becomes smaller than the inner cutter 2.
It has the disadvantage that it may cause severe irritation and may not feel good on the skin.

[Purpose of the invention]

The present invention has been made in view of the above points, and its purpose is to adjust the rate of hair introduction into the hair introduction hole of the fixed blade, the strength of irritation to the skin, and the touch to the skin depending on the characteristics of the skin. The purpose of the present invention is to provide an electric shaver that can be adjusted according to the user's needs.

[Disclosure of the invention]

(Embodiment) FIGS. 1 to 5 show an embodiment of the present invention, in which an outer cutter 1 is a fixed cutter in which a large number of hair introduction holes 13 are bored in the direction of movement of an inner cutter 2, which is a movable cutter. In an electric shaver similar to the conventional example, the electric shaver is equipped with a hair introduction comb 15 in which protruding ribs 17 are spaced apart and hair introduction grooves 18 are provided between the protruding ribs 17 to communicate with the hair introduction holes 13 of the outer cutter 1. The length of each protruding rib 17 in the overlapping direction of the outer cutter 1 and the inner cutter 2, that is, each protruding rib 17
In the first embodiment, as shown in FIGS. 2 and 3,
The height of every other protruding rib 17 is lowered (y ₁ , y ₂ ,
y ₁ , y ₂ ...), and by changing the height of the protruding ribs 17 in this way, it is possible to adjust the balance between irritation to the skin, contact with the skin, and hair introduction rate. be.

That is, when a pair of high protruding ribs 17, 17 with a low protruding rib 17 between them are used so that they both touch the skin, the pair of high protruding ribs 17, 17
The space between the grooves can be regarded as the hair introduction groove 18, and since the groove width is equivalently increased, the irritation to the skin is a little stronger and the hair styling effect is a little worse, but the hair introduction rate is greatly improved. . On the other hand, the high protruding rib 17
When used with the pair of low protruding ribs 17, 17 placed between them both touching the skin, since the high protruding rib 17 exists between the pair of low protruding ribs 17, 17, the hair introduction groove 18 is the original width,
In addition, the high protruding ribs 17 prevent the skin from sinking into the hair introduction grooves 18, and although this reduces the hair introduction rate, it causes less irritation to the skin and improves the hair styling effect. . Therefore, by adjusting the way the protruding ribs 17 touch the skin, the user can shave while adjusting the irritation to the skin, the contact with the skin, and the hair introduction rate. Note that the height of the protruding ribs 17 may be changed continuously in the circumferential direction, and in this case, if the user selects a position where the protruding ribs 17 have an appropriate height according to his/her skin. good.
