Description

DETAILED DESCRIPTION OF THE INVENTION This invention 1+1 relates to the arrangement of blade holes in the outer blade of a reciprocating electric shaver.

Conventionally, as shown in the first row, two sets of blade hole rows A
Direction of A' and BB' Reciprocating direction of inner cutter (2) XX'
and the direction perpendicular to the nK (electric razor r19J scraping direction).
Instead of changing them, they were arranged. In this way, the interval P between the blade holes (2) (center) is continuously changed in the YY' direction,
Since it is parallel to the 'circular direction Y' direction, as shown in the second factor, the band-shaped area (a) where it is difficult to incorporate the whiskers (3) and the area 24
≠A region that contributes to human appearance (OL exists segmentally within the blade hole fi1 group, and in the region (B), for example, the cheek, face, lower part of the mouth, lower part of the nose, where beard grows, etc. There was a drawback that it could not be used effectively even if the degrees of accuracy were different, and it could not be used smoothly in area (A).''t 7t,
Since the blade of the inner blade (2) and the blade hole arrangement of the blade hole row BB' are parallel, the cut of the whiskers (3) is 1rJ.
At 1 o'clock, the 9J cut was large, and there were problems such as poor cutting quality and battery consumption.

Also, as shown in Fig. 3, although some blade holes were curved in the direction of the hole row BB'τYY', the shapes of the blade holes Ill were all the same, and the interval P between the blade holes Ill was a constant pitch. As a result, the introduction of the beard varies depending on the area to be shaved and individual differences, resulting in slow shaving speed and disadvantages such as unshaved parts.

``Misfire'' is an attempt to address the shortcomings of the conventional examples mentioned above, and its purpose is to dramatically improve the performance of the ``Apologetics''.'' small,
The outer blade of the razor (Ji) is provided with an electric power that can cut the beard more effectively.

Is this invention the following? This will be explained in detail with reference to the attached drawings. The n-rc cutter hole H9 drilled in the outer cutter (4) is configured like a fourth hole. The two sets of parallel lines are of course shown in the blade hole rows AA' and BB', and the intersection of the double blade hole rows AA' and BB' (represented by a mark in Figure 4 above) is the blade hole fl. ) represents the center of As described above, in the present invention, the inner blade is rotated in the direction of the blade hole row BB'(21's forward < Jltttu direction x Column B
A region is provided in which the interval P'z between the blade holes 111 on B' is varied. Historically, the other blade hole row AA' is in the reciprocating cutting direction XX of the inner blade (2) in each of the embodiments shown in FIGS. 4 to 6.
However, in the embodiment shown in FIG. 7, the blade hole array AA' is also inclined in the XX' direction. Apology (3
) The beard pitch of the areas where the beard grows varies, for example, if you list the beard pitch in descending order, it will be under the funeral, under the chin, under the chin, under the chin, and on the cheeks. Furthermore, there are large individual differences, especially between races. However, by changing the interval between the blade holes 111 above the blade hole row BB' that is inclined with respect to the YY' direction as described above, the area (a) where it is difficult to introduce the blade, which is a drawback of the conventional example, is eliminated. Beards can be introduced uniformly in all areas, regardless of individual differences and the region where the beard grows. Also, since the YY' direction and the blade hole row BB' are not parallel, and the cutting surface ♂ blade hole row BB' of the inner blade +21 is not parallel, the hairs (3) are not cut at the same time, and the cutting timing t VJ'mr is released at a different angle, so it's low load and has a Gino flavor. Furthermore, by continuously changing the blade hole opening distance, the electric shaver can be formed with a U-shape or a slight deformation with less slight deformation in the case of electric razors that are curved outward in a U-shape. The gap between the inner and outer blades is small, and the stone quality is the same as above, giving it a 9I taste.

In the embodiments shown in FIGS. 5 to 7, a short hole (la) with a substantially square center and a long hole (1b) with a substantially square end in the YY' direction are used. The part you had? Set it up
By tilting the blade hole row BB' to the Y' direction,
Moreover, are the blade holes (2) adjacent in the xx′ direction? They are arranged in intersecting directions so that their long sides are substantially orthogonal to each other. In the embodiment shown in FIG. 5, the slope is changed linearly, in the embodiment shown in FIG. 6 it is changed into a curved line, and in the example shown in FIG.
It is inclined with respect to both the Y' direction and the XX' direction. In the illustrated example, the blade hole Ill is a continuous short hole (la).
Although it is made to change continuously from to long hole (ib), it does not have to be continuous C-like. Moreover, a short hole f may be further arranged at the 14th pass from the periphery of the long hole (1b). Like Jin,
Since the center is the short hole (1a) and the circumferential part or the long hole (1b) in the direction of It is possible to shave short.Also, by adjusting the blade hole (2) that touches p1 in the intersecting direction of f, the blade hole t21 will be oriented in two directions, and the beard Hironto r, l: Particularly in the case of the embodiment shown in Fig. 8, by also inclining the xx' axis and the blade hole row AA', it is possible to make the cuts uniform over the entire area of the inner blade (2). 1116 wear of the bright part and the FTV inner blade can be prevented.

As described above, the present invention provides a PL area in which the direction of the blade holes is inclined with respect to the direction perpendicular to the reciprocating direction of the inner cutter, and the interval r between the blade holes on the inclined blade hole row is changed. Therefore, the area (a) that is difficult to shave with conventional beards is eliminated, and there are individual differences and beard shaving! There is no variation in the degree of inhumanity of the beard depending on the part, and it is possible to achieve a high degree of beard introduction in one place. , J-cutting with low load by varying t at the time of cutting becomes possible, and furthermore, it is possible to continuously change the distance between the holes.
External force r When the outer cutter is curved into a U-shape and installed in the external force frame, the slight change in the outer cutter is reduced, and the gap between the inner and outer cutters is smaller! , I. It has the advantage that it has the same eyebrow properties as above and has a good Gino taste.
