Abstract

PURPOSE:To enable whiskers to be effectively moved into the shaving cutter hole of an external shaving cutter, for the whiskers in any case of an angle formed between the whiskers and skin by setting the shaving head sections of the external shaving cutter in the width direction, and by making the radii of the shaving head sections different from each other to be larger or smaller. CONSTITUTION:The radii R of the external side sections of the shaving head sections 7a, 7b of an external shaving cutter 7 are respectively made larger, and the radii of the internal side sections are respectively made smaller. In other words, in the respective shaving head sections 7a, 7b, two lines of the sections of larger radii R and the sections of smaller radii R formed in the same circles are arranged. However, the whiskers 22 of small phi not to be moved into a shaving cutter hole on the side of the larger radius R of the first line shaving head section 7a are in a state to be easily moved into the shaving cutter hole, on the side of the second line shaving head section 7b, as the radius R is small and phi approximates 90 deg.. In this manner, by the external shaving cutter 7 having the section of the different radius R, a device can cope with any case of the angle phi formed between skin and the whiskers 22.

となっている。[Problem to be solved by the invention] The shape of the reciprocating inner cutter 5' is as shown in FIG.
The majority are semicircular with a - radius (approximately R3 or R6). Further, the inner cutters 5' are arranged in one row, and the outer cutters 7' and their shaving heads 21 are arranged in one row according to the shape of the inner cutters 5'.

な従来の電気かみそりの外刃７′には次のような問題が
あった。By the way, one way to evaluate the performance of an electric razor is to see how well it can fit hair into the blade holes formed in the outer blade. The outer cutter 7' of the conventional electric shaver as shown in FIG. 10 has the following problems.

ができる。FIG. 11 shows the case where the radius R of the head portion 21 of the outer cutter 7' is large, and FIG. 12 shows the case where the radius R of the head ff1S21 is small. As shown in FIGS. 11 and 12, when the outer cutter 7' is pressed against the skin, the beard 22 and the outer cutter 7'
Let θ be the angle it makes with the blade surface, the closer θ is to 90°, the more
The possibility that the whiskers 22 will hit the blade between the blade holes is reduced, and the whiskers 22 will more easily enter the blade holes. However, the beard 22 grows at various angles φ with respect to the skin, and as shown in FIG. 11, when the radius R is large, the beard 22 with a large φ grows at
is close to 90° and θ is 90° for whiskers 22 where φ is small.
° Becomes larger. Therefore, when the outer cutter 7' has a large radius R, the whiskers 22 having a large diameter can be effectively inserted into the blade hole. Further, as shown in FIG. 12, in the case of the outer cutter 7' having a small radius R, contrary to the above, it is possible to effectively insert the whisker 22 having a small φ into the cutter hole.

しかしながら、肌に対する角度φのあらゆる場合に対し

形状が１ａ類しかないということは、ある角度φの髭２
２に対して刃穴に入りにくくなるということである。However, the fact that the shape of the radius R of the outer cutter 7' is only of type 1a means that the outer cutter 7' has only a type 1a shape in order to effectively insert it into the cutter hole for all angles φ with respect to the skin.
This means that it is more difficult to fit into the hole of the blade than No.2.

本発明は、上述の７点に鑑みて提供したものであって、
肌に対してあらゆる角度で生えている髭を効果的に外刃

することを目的としたものである。The present invention has been provided in view of the above seven points, and includes:
To provide a reciprocating electric shaver capable of effectively inserting beards growing at all angles to the skin into the blade holes of the outer blade.

［課題を解決するための手段］ 本発明は、外刃の剃りヘッド部を幅方向に複数列設ける

のである。[Means for Solving the Problems] According to the present invention, a plurality of rows of shaving head portions of the outer cutter are provided in the width direction, and the radii of the shaving blade portions are varied in size.

It is designed so that it can be inserted into the blade hole of the blade.

FIG. 1 is an overall perspective view, FIG. 2 is an exploded perspective view, and FIG. 3 is a sectional view. An eccentric balancer 2 having a substantially semicircular plate shape is attached to the output shaft of the motor 1, and an eccentric cam pin 3 is press-fitted and fixed to the eccentric balancer 2. The eccentric cam pin 3 is loosely fitted into a bearing portion 8 formed on the lower surface of the drive element 4, which is formed in a substantially W-shape, so that the rotational motion of the motor 1 is converted into reciprocating motion.

ものである。A bushing 9 protrudes from 15b, and the inner cutter 5 is attached to the bushing 9 by a pin 15. *In addition, the outer cutter 7 frame 6 with the outer cutter 7 mounted thereon is attached to the upper part of the main body case 11°12. The inner cutter 5 has two rows of shaving head portions 5 a and 5 b formed in the width direction, and the outer cutter 7 disposed with a predetermined gap from the inner cutter 5 similarly has two rows of shaving head portions 7 . a, 7 b. In this embodiment, as shown in FIG.
, 7b, the radius R of the outer part is made thicker, and the radius R of the inner part is made smaller. In other words, each of the shaving heads $7a, 7b has two rows of shaving heads 7a and 7b in which a portion with a large radius R and a portion with a small radius R are formed in the same circular arc.

なるため、髭２２が刃穴に入り易い状態となっている。Therefore, the whiskers 22 that do not fit into the blade hole and have a small φ on the side of the first row of shaving heads s7a with a large radius R, have a small radius R of the second row of shaving heads i7h, so that θ is close to 90°. Therefore, the beard 22 is in a state where it is easy to enter the blade hole.

7e is also formed in three rows. As shown in FIG. 8, the outer shaving head 7a is formed with the largest radius R, the central shaving head 7b is formed with a medium radius R, and the other outer shaving head 7c is formed with the largest radius R. The radius R is the smallest. In this embodiment, one shaving head portion 7at 7 is used.
b, 7c are each a uniform radius. With this configuration, any hair 22 can be effectively inserted into the cut hole of the outer cutter 7.

By providing multiple rows of shaving head sections and varying the radius of the shaving head section, it is possible to effectively cut the beard into the blade hole of the outer blade, regardless of the angle between the beard and the skin. Therefore, when shaving with an electric razor, the shaver can be shaved in a short time.
