Description

[Detailed description of the invention] (Technical field) The present invention relates to a reciprocating electric shaver.

(Background Art) Generally, the thickness and angle of hair on the cheeks and chin differ depending on the person.

On the other hand, as shown in FIGS. 4 and 5, there is a reciprocating electric blade in which an inner blade A is slidably pressed against the inner surface of an outer blade A, which has a large number of hair introduction holes, mouths, etc. In a razor, the skew angle (
Scissor angle) The larger the θ, the better the sharpness and the ability to cut even thick beards.In particular, for people with thick beards, the skew angle θ of the inner blade should be set between 15° and 40°. When the cutting angle is set to about ', the cutting resistance of the whiskers H is low and a good cutting quality can be obtained. However, if the skinny angle θ of the inner blade H is large, the beard H
If the beard H is thin or the brushing angle of the beard H is small, as shown in Fig. 6, when the inner blade C is slid in the two directions of the arrows to cut the beard H, the beard H will close to the beard introduction hole. Sliding on the edge of the mouth in the direction of the arrow H, the root of the beard H was pulled, causing unpleasant irritation, and the beard H could not be cut smoothly. There were many cases where it was defeated by the inner blade and could not be cut too short.

Therefore, when the beard H is thick, the larger the skinny angle θ of the inner blade H, the better. Conversely, when the beard H is thin or the nap angle of the beard H is small, the smaller the skew angle θ of the inner blade H, the better. .

However, in conventional reciprocating electric razors, the skew angle θ of the inner blade H is constant, so the problem is that it is not possible to shave efficiently in accordance with the characteristics of the beard, such as the thickness of the beard H and the nap angle. was there.

(Object of the Invention) The present invention has been made in order to solve the above-mentioned conventional problems, and it is possible to freely change the skinny angle of the inner cutter according to the characteristics of the beard. It is an object of the present invention to provide a reciprocating electric razor that can shave smoothly even if the brushing angles are different.

(Disclosure of the Invention) An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In Figures 1 to 3, the outer blade 1
is formed by curving a flexible outer cutter plate 3 in a U-shape in which a large number of hair introduction holes 2 are formed, and is attached to an outer cutter base 4, and the outer cutter 1 is An inner cutter 5 is pressed against the inner surface so as to be slidable back and forth. The inner cutter 5 includes a large number of substantially arc-shaped inner cutter blades 6.6. which are in pressure contact with the inner surface of the outer cutter plate 3.・
5, the inner blade 6.6. ... are movably attached to an inner cutter base 7 made of, for example, a synthetic resin material. Inner blade 6.6. . . . one end and the other end are connected separately with a connecting body 8.9,
On the other hand, the inner blade 6.6. ... A protruding strip 10 is formed in the longitudinal direction at the center of the inner cutter base 7 on which a better inner cutter 5 is mounted, and furthermore, a protruding strip 10 is formed at regular intervals over the entire length of the protruding strip 10.
Numerous Surin) U, U.

..., and an inner cutter blade 6.6. 11, u, . . . and the inner blade grade 6.6. . . . A connecting body 8.9, in which one end and the other end are connected separately, is movably placed and attached on both side edges tz, tz of the inner cutter base 70. Further, a screw hole 14 is bored in the upright wall plate installed at one end of the inner cutter base 7, and one of the connecting bodies 8
A retaining hole Is is carved in the end face of one end, and a screw structure is rotatably extracted, which is a means for variably forming the skew angle θ of the inner cutter 5 in the retaining large intestine by screwing it into the screw hole 14. In the same way, a screw hole is bored in the upright wall 17 provided at the other end of the inner cutter base 7, and the end surface of the other end of the other connecting body 9 is engaged. An engaging hole 19 is cut in the screw hole 19, and a screw field, which is a means for variably forming the skew angle θ of the inner cutter 5 in the engaging hole 19 by screwing a general screw, is rotatable and cannot be removed. By tightening and loosening pins 20 and 20, the connecting bodies 8 and 9 are attached to the inner cutter base 7 so as to be movable in opposite directions. Holding hole 1
Engagement Ota around 5 and 19.

At 19, there is a screw sum, which is a skew angle variable means, and a large part 2 of the addition.
Nulit* is formed so that 1.22 fits smoothly.

In addition, the protrusions 10 and the inner cutter base 7 have both side edges 12 and 21, which are connected and reinforced at 21 and 21, respectively.
, '21.21 is formed with a protrusion 4 that fits into the connecting body 8.9 and guides the movement of the inner cutter 5. The inner cutter base 7 is connected to the reciprocating drive unit U via a joint.

Next, the operating state of the embodiment of the present invention will be explained with reference to FIG. 3. FIG. This shows a state in which the skew angle θ is 0 degrees, and when the screws 16 and 20 are loosened from this state, the first connecting body 8 and the second connecting body 9 move in opposite directions, as shown in FIG. As shown by the mountain, the inner blade 6 is inclined at the skew angle θ, so when the screw 16.20 is tightened, the first connecting body 8
and the second connecting body 9 move in opposite directions to each other and move as shown in FIG.
As shown in c), the inner blade 6 is inclined at a skinny angle θ in the opposite direction to Fig. 3 1b).
6. The Siskew angle θ can be freely set by the amount of operation.

(Effects of the Invention) As described above, the reciprocating electric shaver according to the present invention has the inner cutter slidably pressed against the inner surface of the outer cutter having a large number of hair introduction holes. Since it is characterized by providing a means for forming the skinny angle of the inner cutter in a variable manner, the skew angle of the inner cutter can be easily changed according to the beard, so that it is possible to easily change the skew angle of the inner cutter according to the thickness of the beard or the nap. Even if the corners are different, you can shave efficiently and cut the beard short.
