Description

[Detailed explanation of the idea] The present invention relates to the structure of the shaving blade of an electric razor.

In recent years, many electric razors have been equipped with a razor blade, but conventional razor blades have drawbacks such as a small amount of protrusion from the electric razor body, or the position of the razor blade when in use. Not only could I not shave the targeted hair properly, but if I got infected, I would end up shaving areas I didn't want to shave.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, and the gist thereof is to include a case member having a case in which a drive unit is housed and an outer cutter frame, and a case member that is attached to the outer cutter frame and has an inner inner surface. an outer blade with which the blade slides into shaving; a scraper frame having one end rotatably pivoted to the inner wall of the case member and the other end protruding from a hole provided in a side wall of the case member; a scraping block having a blade and a scraping movable blade that slides in pressure contact with the scraping fixed blade, the scraping block being attached to the other end of the scraping frame; a spring member for positioning the scratching block in a first position at a lower position near the side wall of the case member and a second position at an upper position close to the outer cutter by a spring force thereof; A cutting edge is formed at one end remote from the outer cutter in the first position and the second position, and an outer cutter cover part that covers at least a part of the outer cutter in the second position is formed at the other end. This is an electric razor with a sharp blade structure.

The present invention will be explained in detail below with reference to the drawings.

Fig. 1 is a front view showing one embodiment of the present invention, and Fig. 2 is a front view showing an embodiment of the present invention.
3 is a plan view of FIGS. 1, 2, and 4; FIG. 4 is a sectional view of the switch; and FIG. 5 is a state of use of an embodiment of the present invention. FIG. 6 is a perspective view showing another embodiment of the present invention.

Reference numeral 1 denotes a case that houses main equipment such as a motor 10, which is the main body of the electric razor.

Reference numeral 2 denotes an outer cutter frame detachably attached to the case, and the case 1 and the outer cutter frame 2 constitute a case member 35 of the electric razor.

Here, pins 3 are provided on two opposing surfaces of the outer cutter 2.

The outer cutter frame 2 has a structure in which an outer cutter mounting member 14 to which the outer cutter 13 is attached is attached in a detachable manner.

Reference numeral 4 denotes a textured decorative board made of plastic or the like, which is attached to a textured frame 5 made of a metal plate, a plastic plate, or the like.

In addition, the scuffing decorative board 4 engages the scuffing fixed blade 6, and the movable scuffing blade 7 is fixed to the scuffing fixed blade 6 by a scuffing blade pressing panel 9 such as a plate blade and a pin 8 provided on the scuffing fixed blade 6. It's forcing me.

In this way, the scuffing decorative board 4, the scuffing fixed blade 6, the movable scuffing blade 7, the scuffing blade pressing panel 9, and the pin 8 constitute the scuffing block 36.

The end portion of the movable scraping blade 7 is formed by bending or the like to integrally form a portion 7a that engages with the engaging portion 20 of the vibrator.

Further, the bent part that is housed in the outer cutter frame 2 has a shape that is almost the same as that of the cutter frame 5.

10 is a motor.

Reference numerals 11 and 12 designate inner cutters, which, as is well known, are engaged with a vibrator 19 that is reciprocated by an eccentric cam provided on a motor 10, are reciprocated, and are moved by a coil spring or the like provided on the drive machine to cause an outer cutter 13. It comes in close contact with the blade and shaves the beard with a reciprocating motion.

Reference numeral 14 designates an outer cutter attachment member made of synthetic resin or the like for attaching the outer cutter 13 to the retaining outer cutter frame 2.

Reference numeral 15 denotes a click spring for holding the scraping blade block in the first position and the second position.

One end of the spring is attached to a spring hook portion 21 formed integrally with the outer cutter frame 2, and the other end is attached to a spring hook portion 22 provided on the edge frame 5.

Reference numeral 16 denotes a pin for rotating the cutter frame 5 about the pin 3 by interlocking with the switch button 17, and makes linear reciprocating motion in the direction of the arrow.

18 is a hole provided in the side wall 2 of the outer cutter frame through which the movable scraping blade 7 and the scraping frame 5 pass.

19 in Figure 3 attaches the outer cutter 11 and 12, and the motor 1
This is a vibrator that reciprocates with a power of 0, and 20 is an engagement portion provided on the vibrator 19 that drives the movable scraping blade 7.

When the scraping blade is not in use, the scraping blade block is stored on the side wall of the outer cutter frame 2 near the case 1.

This is called the first position, which is the lower position. At this time, the engaging part 20 of the vibrator and the movable scraping blade 7 are disengaged, and even if the inner cutters 11 and 12 are being driven, the movable scraping blade 7 is driven. Not done.

When the user moves the switch button 17 in the direction of arrow a (Fig. 1) to use the scraping blade, pin 1
6 (FIG. 4) moves upward, pushes up the secured portion 5a of the crease frame 5, and rotates around the pin 3.

At this time, the force of the spring 15 automatically moves the scraping blade to the second position at the upper position in the state of use shown by the two-dot chain line in FIGS. 2 and 4.

In the spring 15, a spring hook provided on the edge frame 5 on one side is engaged with a portion 22, and a spring hook provided on the outer cutter frame 2 on the other side is engaged with a portion 21.

In this case, the cutter block 36 has a cutting edge 37 formed at one end remote from the outer cutter 13.

During the movement from the first position to the second position, the movable scraping blade 7 engages with the retaining portion 20 of the vibrator 19, and the movable scraping blade 7 makes a linear reciprocating motion.

At this time, since the outer cutter 13 is covered by the outer cutter cover portion 38 formed at the end of the scratched decorative board 4 on the outer cutter 13 side, the fifth
As shown in the figure, only the target area is shaved, and there is no need to cut off unnecessary areas with the outer blade 13.

In the above embodiment, the textured decorative plate covers the outer cutter, but the present invention is not limited to this.

For example, instead of using a scuffing decorative board, a fixed scuffing blade is constructed in one piece so as to double as a scuffing frame, and parts constituting the scuffing blade block, such as a movable scuffing blade, are locked to the fixed scuffing blade, and the parts constituting the scuffing blade block, such as a movable scuffing blade, are locked to the second position. In this case, the sharpening fixed blade may cover the outer blade.

In short, if the members constituting the scraping blade block can cover the outer blade, the effect can be fully demonstrated.

Further, in the embodiment, the rotation center (attachment portion) of the scraping blade block is provided in the outer cutter frame, but the present invention is not limited to this, and the same effect can be obtained even if the rotation center is provided in the case.

FIG. 6 shows the case of a single outer cutter.

30 is a case 31 is a sharpening fixed blade, 32 is an outer blade frame, 3
3 is an outer blade, and 34 is a scratched decorative board.

As mentioned above, in this invention, when the scratching block moves to the second position, the outer blade cover part covers the outer blade, so when using the scratching blade, it is possible to ensure that hairs that do not want to be shaved are shaved with the outer blade. This can be prevented, and the shaving blade allows you to shave only the areas you want to shave.

Furthermore, since the scraping blade protrudes to the second position, there is no obstacle to its use, making it easier to use.

On the other hand, if you do not use the scraping blade, the scraping blade is the first
Since it lowers to the position, the scraping blade does not get in the way when using the outer blade.
