Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric razor having an arch outer blade and a slit outer blade, and more particularly to an electric razor capable of reliably and efficiently guiding a beard to a slit outer blade.

[0002]

2. Description of the Related Art An electric razor has been developed with a triple outer blade type in order to shave deeply and efficiently. This electric razor can reduce the radius of curvature of the mesh blade that is curved in an arch shape, so that the protruding portion can be closely shaved along the projection. In addition, there is a feature that the shaving can be efficiently performed with the triple outer blade. Although the triple electric razor has the feature of being able to shave efficiently, it has the disadvantage that habitual beards can hardly be cut. This is because the beard does not protrude from the skin in the vertical direction, but curves and makes the tip adhere to the skin.
A beard of this shape cannot be inserted into a shaving hole that is open on the arch outer blade.

In order to solve this problem, a triple electric shaver having a slit outer blade disposed between two arch outer blades has been developed. In this electric razor, the upper surface of the slit outer blade has a planar shape and a parallel slit is opened.

[0004]

The electric razor in which the slit outer blades are arranged between the arch outer blades can cut the habit more quickly than the electric razor having three arch outer blades. However, the electric shaver of this structure,
The habit must not be cut efficiently enough to be satisfactory. FIGS. 1 and 2 show a state in which the slit outer blade 2 disposed between the arch outer blades 1 cuts a beard K. FIG. As shown in these figures, the electric razor reciprocates the arch outer blade 1 and the slit outer blade 2 along the skin H, and
To cut.

[0005] As shown in these figures, many whiskers are curved. Furthermore, many habits do not grow at right angles to the skin, but grow in a posture inclined in a direction parallel to the skin. For this reason, the habit mustache does not easily protrude from the skin, and cannot be guided into the shaving hole of the arch outer blade. In particular, as shown in the figure, if the tip is curved and comes into close contact with the skin, it cannot be guided into the shaving hole of the arch outer blade.

[0006] In order for the slit outer blade to cut the habit of this shape, it is necessary to induce the habit into the parallel slit of the slit outer blade. However, as shown in FIGS. 1 and 2, when the electric razor in which the slit outer blade is disposed between the arch outer blades is reciprocated while pressing against the skin H, the arch outer blade 1 crushes the beard K. The skin H. Since the habit K in this posture does not protrude from the skin H, it cannot be guided into the parallel slit of the slit outer blade 2.

FIG. 1 shows a state in which the slit outer blade 2 is moved in a direction in which the beard K grows. When the slit outer blade 2 is moved in this direction, the curved beard K is crushed by the arch outer blade 1 that moves ahead of the slit outer blade 2, comes into close contact with the skin H, and is guided into the parallel slit. Disappears. In particular, the long habit K to be shaved is securely brought into close contact with the skin H on the preceding arch outer blade 1, and cannot be cut by the slit outer blade 2.

As shown in FIG. 2, if the slit outer blade 2 is moved in a direction opposite to that of FIG. 1, that is, in a direction opposite to the direction in which the beard K grows, it becomes more difficult to cut the beard K. This is because the leading arch outer blade 1 not only presses the beard K against the skin H, but also turns the direction of the beard K sideways so that it cannot be directed in a direction parallel to the parallel slit. In order to efficiently cut the beard K with the parallel slit, it is necessary to direct the long beard in a direction parallel to the parallel slit and to guide the long beard to the parallel slit.

In order to make the beard more parallel to the parallel slit, an electric razor having a comb-shaped outer slit has been developed. However, even if the comb-shaped slit outer blade is moved along the skin, the arch outer blade presses the beard and makes close contact with the skin before the slit outer blade, or
An electric razor in which the direction of the beard is out of order and the tip of the out-of-direction beard is pressed by an arch outer blade cannot reliably cut the beard even with a comb-shaped slit outer blade.

The present invention has been developed to solve these disadvantages. An important object of the present invention is
An object of the present invention is to provide an electric razor that can reliably cut a beard and that can efficiently and beautifully shave with an arch outer blade.

[0011]

The electric razor according to the present invention has an arch outer blade 1 having an arch-shaped mesh blade 1A, and a blade edge along the inner surface of the arch outer blade 1. Arch inner blade 3 whose edge slides on the inner surface of arch outer blade 1
And are arranged in parallel adjacent to the arch outer blade 1, and
It has a slit outer blade 2 having a parallel blade 2A opening a plurality of parallel slits 2a extending in the lateral direction, and a blade edge along the inner surface of the slit outer blade 2. And a comb 4 disposed adjacent to and parallel to the slit outer blade 2.

As shown in FIG. 3, the electric razor having this structure includes a comb 4 prior to an arch outer blade 1 and a slit outer blade 2.
Moves toward the habit K. The comb 4 moving in the direction of the arrow is in a state in which the slit outer blade 2 and the arch outer blade 1 do not press the beard K, in other words, a state in which the beard K is curved and protrudes from the skin H in an arch shape. The direction of the slit outer blade 2 is aligned with the posture of inviting the slit outer blade 2 into the parallel slit 2a. The beard K directed in the direction of the parallel slit 2a is quickly led into the parallel slit 2a of the slit outer blade 2. Even in this state, the beard K is not pressed by the arch outer blade 1 as in a conventional electric razor, and can be freely changed in direction. The directions are also aligned by the parallel slits 2a. Conversely, when the slit outer blade 2 is moved toward the direction in which the beard K grows,
The beard K passes through the gap of the comb 4 and is guided to the parallel slit 2 a of the slit outer blade 2. At this time, the beard K, which can be freely deformed, can be lifted away from the skin H, and the beard K can be more reliably guided into the parallel slit 2a, so that the slit outer blade 2 reliably cuts the beard K. further,
Although not shown, the whiskers that grow in parallel with the comb 4 and the slit outer blade 2 are aligned with the moving comb 4 in the direction of the parallel slit 2a of the slit outer blade 2 in the same manner as the whiskers K shown in FIG. ,
It is invited into the parallel slit 2a. For this reason, the habit that faces in this direction is also reliably cut by the slit outer blade 2.

Further, according to a second aspect of the present invention, the arch outer blade 1 and the slit outer blade 2 are disposed so as to be able to freely enter and exit at a position protruding from the comb 4. The position where the arch outer blade 1 and the slit outer blade 2 are pushed down the most is the same plane as the tip of the comb 4. In the electric razor having this structure, the comb 4, the slit outer blade 2, and the arch outer blade 1 are brought into contact with the skin H, and cut the beard K most efficiently.

Furthermore, in the electric razor according to a fourth aspect of the present invention, the parallel blade 2A of the slit outer blade 2 is made thicker than the arch outer blade 1, and the opening area of the parallel slit 2a is made smaller than the opening area of the shaving hole. Also has a large opening. The thick parallel blade 2A is
By increasing the width of the parallel slits 2a, the invitation of the beard K is improved and damage to the skin H can be reduced. Thin mesh blade 1A
Shaves the beard guided to the shaving hole.

Further, in the electric shaver according to claim 5 of the present invention, the interval between the combs 4 is formed wider than the interval between the parallel slits 2a of the slit outer blade 2. Comb 4 of this structure
Can more reliably guide the beard K and align the directions.

In the electric shaver according to a sixth aspect of the present invention, a slit outer blade 2 is provided on both sides of the arch outer blade 1, and a comb 4 is provided on both sides of the slit outer blade 2. 7
In this electric razor, the arch outer blade 1 has two rows. Since the electric shaver of this structure has both sides of the arch outer blade 1 symmetrical, it can be moved in both directions to efficiently cut a beard or the like. Furthermore, in the electric razor according to the eighth aspect, since the tip portion of the comb 4 is curved and projected outward, the electric shaver can be comfortably brought into contact with the skin, and the beard or the like can be efficiently guided to the slit outer blade 2.

[0017]

Embodiments of the present invention will be described below with reference to the drawings. However, the following examples illustrate an electric shaver for embodying the technical idea of the present invention, and the present invention does not specify the electric shaver as follows.

Further, in this specification, in order to make it easier to understand the claims, the numbers corresponding to the members shown in the embodiments will be referred to as “claims” and “ In the column of “means”.
However, the members described in the claims are not limited to the members of the embodiments.

The electric razor shown in FIGS.
A series of arch outer blades 1, two series of slit outer blades 2, three rows of combs 4, and an outer blade case 6 in which the arch outer blades 1 and the slit outer blades 2 are arranged and mounted in parallel. , An outer cutter frame 7 to which an outer cutter case 6 is detachably mounted, an arch inner cutter 3 slid by being pressed against the inner surface of the arch outer cutter 1, and a slit outer cutter 2
Inner blade 5 which is pressed and slid on the inner surface of the inner blade, and the inner blade base 1 in which the arch inner blade 3 and the slit inner blade 5 are connected.
1 and a drive mechanism (not shown) for reciprocating the inner blade base 11.

As shown in an exploded perspective view of FIG. 6, the two arch outer blades 1 and the two slit outer blades 2 can be moved up and down independently via an intermediate base 6a. That is, it is attached to the outer blade case 6 so that it can enter and exit. The slit outer blade 2 is arranged adjacent to and outside of the two arch outer blades 1 in parallel. The arch outer blade 1 is disposed at a position protruding from the slit outer blade 2 in the pushed-out state. The reason is that the arch outer blade 1 is surely pressed against the skin to finish and shave the beard neatly.

As shown in FIG. 6, the arch outer blade 1 has a mesh blade 1A fixed to a plastic holder 1B. The mesh blade 1A has a thickness of, for example, 30 to 100 μm.
m, optimally about 50 μm, is a thin metal plate, which is curved in an arch shape and fixed to the holder 1B. The mesh blade 1A has numerous shaving holes. The holder 1B is formed by molding a hard plastic into a rectangular prismatic shape having upper and lower openings.

As shown in FIG. 6, the slit outer blade 2 has a parallel blade 2A fixed to a plastic holder 2B. As shown in FIGS. 7 and 8, the parallel blade 2A
A plurality of parallel slits 2a are opened in a metal plate extending in the lateral direction. The parallel blade 2A is formed by bending a metal plate into a rectangular shape having a flat upper surface and extending from the upper and outer corners to an outer vertical portion to open a parallel slit 2a. The slit outer blade 2 shown in FIGS. 7 and 8 has a tapered shape in which the width of the parallel slit 2a increases outward. The parallel blade 2A of this shape has a feature that the beard K can be aligned like a comb and smoothly guided by the parallel slit 2a.

The parallel blade 2A shown in FIGS. 7 and 8 has a flat upper surface. In the electric shaver of the present invention, the upper surface of the parallel blade does not necessarily have to be completely flat. For example,
It may be curved to a radius of curvature larger than the radius of curvature of the arch outer blade 1 that is curved in an arch shape, and may have a substantially planar shape.

The thickness of the parallel blade 2A is thicker than that of the mesh blade 1A, for example, 0.1 to 0.5 mm, optimally 0.2 to 0.5 mm.
0.3 mm, 2 to 10 times, and optimally about 5 times the mesh blade 1A. The reason why the thickness of the parallel blade 2A is increased is to increase the width of the slit outer blade 2 and reduce damage to the skin H. In order to smoothly guide the beard K to the parallel slit 2a, it is necessary to increase the width of the parallel slit 2a.
However, when the width of the parallel slit 2a is widened, the skin H is easily pressed into the skin, and the skin H is easily damaged by the slit inner blade 5 sliding on the inner surface. In order to prevent this adverse effect, the parallel blade 2A is made thick. Thick parallel blade 2
In A, the skin is not damaged by the slit inner blade 5 unless the skin is deeply pressed into the parallel slit 2a.

The width of the parallel slit 2a is increased so that the parallel blade 2A, which is thicker than the mesh blade 1A of the arch outer blade 1, can surely cut the beard K and reduce the damage to the skin. The parallel blade of the slit outer blade 2 roughly shave the beard K. The rough shaved beard K is finally shaved by the arch outer blade 1 moved along the skin following the slit outer blade 2. The tip of the short-cut beard K is easily guided to the shaving hole of the arch outer blade 1, and the shaving is sharply finished with the shaving hole.

The arch outer blade 1 and the slit outer blade 2 are mounted on the outer blade case 6 so that they can enter and exit independently. The arch outer blade 1 and the slit outer blade 2 fix the mesh blade 1A or the parallel blade 2A to plastic holders 1B and 2B, respectively.

The arch outer blade 1 and the slit outer blade 2 are elastically pushed out toward the skin via an end spring 16 which is a coil spring. The end spring 16 presses the arch outer blade 1 and the slit outer blade 2 against the skin with a large stroke. When the arch outer blade 1 and the slit outer blade 2 are elastically pushed out of the outer blade case 6 and are pushed out by the end spring 16, as shown in FIGS. Although it protrudes from the blade 2, when the arch outer blade 1 and the slit outer blade 2 are completely pushed down, the arch outer blade 1 sinks deeply until it is flush with the slit outer blade 2. The beard can be cut with all four outer blades of the arch outer blade 1.

The electric razor of the present invention is characterized in that the beard can be cut into an ideal state with the slit outer blade, and that the shaver can be neatly shaved with the arch outer blade. This is because the electric razor of the present invention arranges the slit outer blade in parallel adjacent to the arch outer blade, and further arranges the comb in parallel adjacent to the slit outer blade. . The electric razor of this structure follows the arch outer blade as before,
The parallel blade does not shave. When shaving by reciprocating the outer blade along the skin, as shown in FIG. 3, the comb moves ahead of the slit outer blade opening the parallel slit. The comb aligns the whiskers that protrude from the skin and securely guides the whiskers into the parallel slits of the outer blades of the slit to cut the comb reliably. The habit cut with the slit outer blade becomes shorter and protrudes from the skin. The beard which is cut short and slightly protrudes from the skin is guided by a shaving hole provided on the net blade of the arch outer blade, and cut further short.

Further, the electric razor according to the second and third aspects of the present invention is arranged so that the arch outer blade and the slit outer blade can enter and exit at a position protruding from the comb. At the position where the slit outer blade is pushed down most, it is flush with the tip of the comb, so if you strongly press the arch outer blade and the slit outer blade, the comb will align the beard securely and the parallel slit of the slit outer blade In a state where the slit outer blade and arch outer blade are not strongly pressed,
Realizes the features that can be used in the same way as an outer blade without a comb.

Further, in the electric razor according to a fourth aspect of the present invention, the parallel blade of the slit outer blade is made thicker than the mesh blade of the arch outer blade, and the opening of the parallel slit is made larger than the shaving hole. ing. The electric razor of this structure has a feature that the beard can be surely cut with the slit outer blade and that the beard can be shaved neatly without damaging the skin. The reason is that the beard is surely guided into the parallel slit that has a large opening, the skin is not damaged by the thick parallel blade, and the beard can be cut short and neatly with the shaving hole of the thin mesh blade.
Thick parallel blades do not damage the skin because they do not shave.

Further, in the electric razor according to the fifth aspect of the present invention, since the interval between the combs is made wider than the interval between the parallel slits of the slit outer blade, the curved beard is reliably guided between the combs. And you can arrange them neatly. The aligned whiskers are promptly guided into the parallel slits of the slit outer blade and are reliably cut.

Further, in the electric razor according to the sixth and seventh aspects of the present invention, a slit outer blade is provided on both sides of the arch outer blade, and a comb is provided on both sides of the slit outer blade. Therefore, there is a feature that both the reciprocating movement of the outer blade can surely cut the habit and shave efficiently.
