Abstract

PURPOSE:To prevent the flying out of the cut mustache waste by forming a blade surface continued to the internal cutting edge of an internal cutting blade into an inclined surface receding in the moving direction as it gets away from the internal cutting edge, and forming a through hole for passing the cut mustache waste on the internal cutting blade. CONSTITUTION:A blade surface continued to the internal cutting edge 2a of an internal cutting blade 2 is formed into an inclined surface 3 receding in the moving direction as it gets away from the internal cutting edge 2, and a through hole 4 for passing the cut mustache waste is formed on the internal cutting edge 2. Hence, the mustache entering into the blade hole of an outer blade 1 is cut by the cooperation with the internal cutting edge 2a, and the cut mustache waste is thrown obliquely downward by the inclined surface 3 continued to the internal cutting edge 2a. The thrown mustache waste is further thrown downward through the through hole 4 formed on the internal cutting blade 2 to avoid the collision of the mustache waste with the internal cutting blade 2. and the mustache waste is restrained from flying out from the blade hole of the outer blade 1 by the collision with the internal cutting blade 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a reciprocating electric shaver, and more particularly to a technique for preventing cut beard shavings from flying out.

[Prior Art] Conventionally, in a reciprocating electric shaver, the beard that enters the cutter hole of the outer cutter is cut by the inner edge of the reciprocating inner cutter blade, and the beard shavings are stored inside the shaver.

[Problems to be Solved by the Invention] However, when cutting beard shavings by reciprocating the inner cutter blade, the cut stubble collides with the reciprocating inner cutter blade and comes out from the cutter hole of the outer cutter. There was a problem that it was unpleasant and unhygienic as it could fly out and adhere to skin or clothes. By the way, as in Utility Model Application Publication No. 58-11464 shown in Fig. 6,
Although it is for a different purpose, there is an example in which the inner cutter blade 2 is provided with a through hole 4, but the whiskers cut by the inner cutter nick of the inner cutter blade 2 do not fly in the direction of the through hole 4 of the inner cutter blade 2, Because it flies horizontally in the direction of movement of the inner blade 2, it collides with the adjacent inner blade, passes through the hole in the outer blade, and flies out to the outside.
There was a problem with the beard flying off.

The present invention was made in view of such problems,
The purpose is to provide a reciprocating electric shaver that prevents cut beard shavings from flying out of the cutter holes of the outer cutter.

[Means for Solving the Problems] The reciprocating electric shaver of the present invention is an electric shaver in which inner blades 2 arranged in parallel in the moving direction reciprocate with respect to an outer cutter 1. The blade surface connected to the edge 2a is formed into an inclined surface 3 that becomes more rearward in the direction of movement as the distance from the inner cutter edge 2a increases, and a through hole 4 is formed in the inner cutter blade 2 to allow hair chips to pass through. It is.

[Function] In this way, the blade surface continuous with the inner cutter edge 2a of the inner cutter blade 2 is formed into the inclined surface 3 that becomes more rearward in the moving direction as the distance from the inner cutter edge 2a increases, and the inner cutter blade 2 is made to pass hair scraps. By forming the through hole 4, the beard that has entered the cutter hole of the outer cutter 1 is cut in cooperation with the inner cutter edge 2a, and the cut beard scraps are obliquely cut by the inclined surface 3 connected to the inner cutter edge 2a. The blown beard chips pass through the through hole 4 formed in the inner cutter blade 2 and are blown further downward, avoiding the beard from colliding with the inner cutter blade 2 and preventing the beard chips from colliding with the inner cutter blade 2. It is designed to prevent the blade from colliding with the blade 2 and flying out from the cutter hole of the outer cutter 1.

[Example] Embodiments of the present invention will be described in detail below based on the drawings.

FIG. 1 shows the overall structure, in which the inner blade 5 is connected to the joint 6.
It is connected to the drive section 8 of the main body 7@ via. Blade hole 9
The outer cutter 1 on which is formed is attached to an outer cutter frame 10, and the outer cutter frame 10 is detachably held in the main body 7, and by operating the switch 11, the power battery inside the main body 7 (
(not shown), the drive unit 8 is reciprocated in a vibrating manner, and the driving force is used to reciprocate the inner cutter body 5 in a vibratory manner, and the hair that has entered the blade hole 9 of the outer cutter 1 is removed from the inner cutter body 5. Cutting can be performed at the two inner cutter horns 2a of the inner cutter blade 2.

Figure 2 shows an inner blade body 5, in which an inner blade 2 formed in the shape of a horseshoe is embedded and supported so as to straddle a blade support part 12 formed in an approximately mouth shape. 12 are connected by lips 13 at both ends and the center in the length direction, increasing the strength thereof. In this way, the lip 13 in the central part where a large amount of beard is cut is reduced, so that the beard tends to fall downward from the blade support part 12. or,
By arranging the lip 13 at the center where the bending moment is most applied, the bending strength of the inner cutter body 5 is effectively increased, and the outer cutter 1
We are ensuring a clear line of cooperation with the government.

Also, among the many inner cutter blades 2..., those at both ends of the inner cutter body 5 in the length direction are lower j as shown in FIG. 2(d).
l*, making it easier for the inner blade body 5 to slide into contact with the external force 1, and to prevent interference between the inner blade 2 and the outer blade 1 even if the skin is strongly pressed against the outer blade 1 during shaving. None (outer blade 1
This prevents damage to the product.

In particular, the inner cutter blades 2 are embedded at both ends of the inner cutter body 5 in the length direction to suppress interference at locations where interference is likely to occur. As shown in FIG. 2(C), the lower end of the inner blade 2 in the open part protrudes from the blade support 12, making it easier to drop the cut hairs downward. .

FIG. 3 shows the manufacturing process of the inner blade 2, in which a beveled portion 14 is formed on the inner and outer surfaces of the inner blade 2 by press working or the like along the inner cutter edge 2a. The upper part of the inner blade is ground along the cutting line and the inner edge is erra :)2
a is formed at an angle smaller than 90°. A through hole 4 is provided below the shank portion 14 through which the cut beard scraps pass.
It is formed. Therefore, the blade surface continuous to the inner cutter edge 2a of the inner cutter blade 2 is formed into an inclined surface 3 which becomes more rearward in the moving direction as the distance from the inner cutter edge 2a is increased, and the beard cut by the inclined surface 3 continuous to the inner cutter edge 2a is formed. The debris is thrown diagonally downward, collides with the adjacent inner blade 2 from diagonally above, is reflected diagonally downward, and falls downward; It is so that it falls downward through it.

FIG. 5 shows the form of the blade hole 9 of the outer cutter 1, and shows the blade hole 9 from a position above the upper end of the blade support 12 to a position below.
A is made small (in other words, the area in Figure 5 is the small hole area, and a is the large hole area. The reason why area b is made into a small hole in this way is that the beard dregs will come out. This not only reduces the probability, but also makes it easier for the outer cutter 1 to bend and conform to the shape of the inner cutter blade 2. This is because the beard will not be able to be shaved well if the beard does not stick together.The position d where the blade hole 9 is made smaller is determined based on the balance between the scattering of the beard, the cut edge and the introduction of the beard.

[Effects of the Invention J] In short, the present invention forms a blade surface that is continuous with the inner edge of the inner cutter blade into an inclined surface that becomes more rearward in the direction of movement as it gets farther from the inner cutter edge, and allows the inner cutter blade to pass through the whiskers. Since the through hole is formed, the cut hair chips can be thrown diagonally downward on the sloped surface connected to the inner blade edge, and the hair chips thrown diagonally downward can pass through the hole formed in the inner blade. This prevents the beard shavings from colliding with the inner cutter blade, and prevents the beard shavings from colliding with the inner cutter blade and flying out from the outer cutter hole. This has the advantage of being able to prevent unpleasant beard shavings from scattering.
