Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates particularly to the external shape of an electric shaver.

Conventionally, the pursuit of sharpness, especially quick shaving performance, has been pursued in the stain-resistant razor 9, but by using the outer blade according to the present invention, this quick shaving performance can be improved.

The present invention will be explained below with reference to figures, but parts not directly related to the present invention will be simplified or omitted.

1ii! Figure 1 is an external view showing an embodiment of the present invention, Figure 2 is a sectional view taken along line A-A of Figure #81, Figure 5 is a partially enlarged view of the outer cutter according to the present invention, and Figure II4 is a cross-section of the outer cutter 3. Fig. 5 is a partially enlarged view of the outer cutter according to another implementation ψ, Fig. W46 is a sectional view of Fig. 5, Fig. 7 is a usage state diagram of the electric shaver according to the present invention, and Fig. 8 is a diagram of Fig. 7. This is an enlarged view.

In all the figures, 1 is a part of the vessel body and is an outer cutter frame for fixing the outer cutter h5, and the outer cutter frame fk is detachably mounted on the main body case 72. 6 is a row of protrusions 5a extending in the direction of the radius of the main body case.
It has a shape that straddles the protrusion, and has an inclination angle tIs with respect to the direction of the inner blade, and has a long hole 5b (like the pore 3C described later) and a large pore area. , has a pore 3C provided in the general part of the pond. As is well known, an outer cutter fitting 9 is fixed to the outer cutter 5, and the upper part of the outer cutter fitting 9 engages with the stepped portion of the outer frame 1 to adjust the height direction of the outer cutter 3. The price will be determined. 4 has a large number of h4a on the inside as shown in Figure 5.
It is resin-molded in the direction shown in Fig. w45, and the outer blade 3 is always held by the inner blade spring 10 built into the upper part of the vibrator 5.
The surface is in contact with the inner surface of the surface.

The transducer 5 is a well-known device.
111) A thin film is provided on four sides of the left and right sides when viewed from the edge, and the thin film is configured to withstand the buckling force of the inner spring and the outward pushing force during shaving, and the thin film is It is a means for vibrating the inner cutter 4 substantially horizontally and horizontally, and is fixed to a motor board 6 for fixing the motor 7 to the main body case 2. A well-known eccentric pin (not shown) is fixed to the tip of the shaft of the motor 7, and the vibration stroke of the inner cutter 4 is twice the eccentricity of this eccentric pin.

With the above structure, when a user wants to shave his beard, he holds the device in his hand, turns it on, and applies external force 5 to his face, but the easiest way for the user to shave is with his thumb. This method involves turning on the switch and pressing the outer cutter 5 so that the center line 11 is almost perpendicular to the skin of the face without changing the grip as shown in FIGS. 7 and 8.

On the other hand, in general, shaving in the opposite direction will give you a deeper and faster shave than 1-@shi.As beards generally grow from the upper part of the throat towards the center of the throat, It is necessary to be able to shave efficiently when shaving in reverse. For this purpose, in the present invention, the blades are placed very close to the center line 11 of the through-cutting outer cutter 3 shown in FIG. A major feature is that a row of protrusions 5a are provided on the front surface. 5th patch 1. As shown in FIGS. 4 and 5, and as described above, a long hole 5b is provided which has a shape that straddles the protrusion row 6a and has an angular change of tll from the inner direction. For this reason, FIG.

When the razor is moved in the direction of the arrow shown in FIG. 8, that is, in the direction of reverse shaving, the protrusions 5a first come into contact with the skin and indent the skin. Then, the whiskers 13 that were in close contact with the skin (even long whiskers) stand up from the skin and fall into the nuclear elongated hole 5b, and while guiding this whisker with the protrusion, the long or short sides of the elongated hole and the outer core 5b are guided. , after cutting off the dip p for close contact sliding action with the inner side 4, the center line 1 in Figures 2, 7, and 8.
The long hole 6b and small hole 5c located on the right side of 1 are machined and finished. In order to take full advantage of the effects of this finishing shave and long hair shave, the height of the protrusion must be at least 2.5 times higher than H) in Figures 4 and 6 by straddling the aforementioned wrinkle protrusions. A hole of length is efficient. This is because the area near the starting point of the protrusion does not come into close contact with the skin, so it is not possible to finish shaving.Also, in the unlikely event that the beard (% long hair) that did not fall into the long hole 5b on the first occasion,
When the hair passes through the protrusion for the first time, the hair is raised up by the protrusion and is no longer in close contact with the skin, or the direction has changed slightly, so it is necessary to shave for the second time. When the electric shaver passes through the same way as described above, there is a much higher possibility that the hair will fall into the elongated hole 5b than with a conventional electric shaver, and there is a very high possibility that the hair will fall off the second time, so it is easier to shave quickly. increases.

As mentioned above, in order for the protrusions to produce the effects mentioned above,
After turning on the body switch, when pressing the outer side against the skin in a natural state, the crease protrusions should fit properly into the skin, and when pressed further, the protrusions should completely sink into the skin. It is desirable to move while scraping the skin and beard, leaving only a slight indentation in the skin. This position is shown in Figure 2.

On the center line 11 of Figure 70m8 or within the range of #, = 30° from this position, and most preferably C θ1w
= Q°A - 60°, and for types with the switch button on the front, the direction away from the switch button (
It is located on the back side).

By doing this, from K, as mentioned above, the long hole 5b has a beard,
It is especially easy to compensate for long hair and allows for quick shaving. Furthermore, since there are elongated holes on both sides of the protrusion that straddle the protrusion, the protrusion and the elongated hole act in the same manner as described above even when moving from the direction opposite to the arrow. In addition, as mentioned above, the present invention has a long pore 5aL' provided in the crotch area and a large area (l). Previously, it was known that the larger the hole in the outer blade, the easier it was for the beard to fall in and be cut, but if it was made larger, the skin would fit into the hole, and the inner blade located on the inner surface of the outer blade would However, if the elongated hole 5b is positioned across the protrusion as in the present invention, the protrusion can be cut into one sieve. The beard will fall into the long hole, but the skin will be pushed away from the inner blade, and even if the skin near the top of the protrusion falls into the long hole, the hair will fall into the long hole. Because the inner blades are not in close contact with each other, it is possible to create an extremely long and wide hole that extends beyond the starting point of the protrusion (range A in Figures 4 and 6) without causing any pain. Furthermore, it is desirable in terms of cost that the inner side can be simply ground into a cylindrical shape like a general electric shaver.
However, in the present invention, the outer protrusion is
Since it is placed near the skin, it receives a force equivalent to the force of pressing it against the skin. This pressing force acts as a force that tries to dent the outer blade, but if the outer cutter is dented, not only will the adhesion with the inner cutter be impaired, but the outer cutter will also be destroyed due to interference with the vibrating inner cutter. I can also see things. Therefore, in the present invention, the elasticity of the beam 6d located around the protrusion and long hole is made wider than the beam of the general part,
Partially thickened to make it stronger. Furthermore, the elongated hole is tilted by 03 with respect to the arrangement direction of the inner cutters, so that even if the $5d is slightly bent, it will not interfere with the inner cutters. In addition, as shown in FIGS. 5 and 5, the pitch of the long holes in the outer blade 5 is increased to match the pitch of the blade 4a of the inner blade 4, and the number of long holes is increased.
The width of one beam 5d is made as small as possible to improve the hole area ratio, but in order to reduce the deflection of the beam 6d, the beam 5d forming the elongated wire hole 5b is connected to the inner blade 14a. let it come into contact,
The hole is supported by the spring force of the inner cutter spring 10 applied inwardly, but as mentioned above, in order to improve the opening ratio, the pitch of the long holes and the pitch of the inner cutter blade are different. Figure, 5th
As shown in FIG. As shown in Fig. 5, the beam 3d which is not in direct contact with the internal force □ blade has a small hole 5C extending from the clasp 5d in contact in the width direction of the electric shaver (direction e in Fig. 1). One of the major advantages is that they are connected by a strong beam with strong deformation that is equal to or higher than the beam to be formed, and that the beam is indirectly reinforced inwardly.

In addition, since the elongated hole 5b has a different direction from the inward direction and has an angle of θ1 shown in FIGS. 3 and 5,
In the piece j of the protrusion, the inner blade comes into contact with the inner cutter or not. In particular, one end of the beam formed by the elongated hole that spans the protrusion must be supported by the blade of the inner cutter, and in order to increase the opening ratio, Even if it is made thinner, it will be a countermeasure against the pressing force when shaving.

As described above, in the present invention, in order to improve quick shaving performance and finish quality when shaving, the width A of the protrusion that is not in close contact with the inner cutter and is inserted in the part without cutting edge (see Fig. 4, *6) (shown) as much as possible, and the elongated hole that spans the protrusion to a height H of the protrusion.
It is longer than 5 times, and the rising angle of the protrusion (Fig. 4, 6)
04) and 03, the starting point of the protrusion does not touch the skin, but a part of the elongated hole is in close contact with the skin to perform the finishing shave and long hair trimming. beam 6d
In order to prevent the workpiece beam 5d from becoming easily deflected due to the projection being installed at the center of the long υ, the element 9 that directly receives the beam at the tip of the inner blade is indirectly installed. It is characterized by a part of the blade that is received by the other side.
In this way, the projections and elongated holes of the young fruit can be fully utilized as described above without impairing the texture, the texture of the skin, the fine shaving properties of the pores, and the durability of the outer blade. In the present invention, the inner side is 1
[-Of course, it can be applied not only to moving types but also to electric shavers with rotating inner blades.
