Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reciprocating electric shaver in which an inner cutter that performs a reciprocating sliding movement slides on the inner surface of an outer cutter curved in a semicylindrical shape. A flat elastic outer blade 2 curved into a semi-cylindrical shape is formed into a rectangular shape that is elongated in the curved direction. A reciprocating electric shaver in which a group of slit-shaped blade holes 4 is provided in approximately half of the blade 2 in the curved direction, and a flocked portion 6 is formed on the inner surface of the uncoated portion 5 of the other approximately half of the outer blade 2. It is.

In a conventional reciprocating electric shaver, as shown in FIG. 1, an outer cutter 2a having a group of cutter holes 4a on almost the entire surface is curved into a semicylindrical shape and fixed to an outer cutter frame 7a. 7a is removably attached to the razor body 3a having the inner blade 1a, so when cleaning beard dregs, the outer blade frame 2a and the inner blade 1a are removed from the razor body 3a and attached to the dedicated brush 8. It is necessary to clean the inner cutter 1a, and also to clean the outer cutter 2a when not in use.
In order to protect the blade hole group 4a and the inner cutter 1a, it was necessary to fit the protective cover 9 one by one, which was troublesome.

The present invention has been made in view of the above points, and its purpose is to eliminate the need for a brush for cleaning the shavings of the inner cutter, and to protect the blade holes of the outer cutter and the inner cutter. To provide a reciprocating electric shaver that can protect blade holes without using a protective cover and is easy to maintain.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

The inner cutter 1 is attached to the drive shaft of the razor main body 3, and is formed by arranging a large number of blades 10 with arched upper edges.

Reference numeral 2 denotes an elastic flat plate-shaped outer cutter which is added to the razor body 3 in a semicircular shape curved along the inner cutter 1, and is formed into a rectangular shape that is long in the direction of curvature. A group of blade holes 4 is formed in approximately half of the outer blade 2 in the curved direction, and a flocked portion 6 is formed on the inner surface of the other approximately half, and a plain portion 5 is formed on the outer surface.

There are two mounting holes 11 at each end of the outer cutter 2 in the curved direction.
is provided.

A spring fixing base 14 is attached to the inner surface of the front plate 13 of the case 12 of the razor body 3, and the other end of the back spring 15, one end of which is hooked to the spring fixing base 14, is attached to the outer blade 2.
The mounting near the blade hole group 4 is removably connected to the hole 11 via a connecting piece 22.

A Y-shaped outer blade operating body 17 is provided on the inner surface of the back plate 16 of the case 12.
is attached to be slidable in the vertical direction, and the tip of the branch 18 of the outer cutter operating body 17 is removably connected to the hole 11 of the outer cutter 2 near the flocked part 6. The base 19 of the operating body 17 is guided by a vertically long operating hole 20 of the back plate 16 to move up and down. When moving up and down, the finger is placed on a protrusion 21 that protrudes outward from the base 19 through the operating hole 20. It is performed by applying pressure to the abdomen.

However, when the outer blade operating body 17 is pushed down and locked against the spring force of the back spring 15, the sixth
As shown in the figure, the blade hole group 4 of the outer cutter 2 is exposed to the outside so as to cover the inner cutter 1, and the plain part 5 and the flocked part 6 of the outer cutter 2 are inside the outer cutter frame 7 and the razor body 3. It is something that can be stored and used to bring good fortune.

Next, when not in use, by unlocking the outer cutter operating body 17, the blade hole group 4 of the outer cutter 2 is inserted into the outer cutter frame 7 and the razor body 3 by the spring force of the back spring 15, as shown in FIG. When pulled in, the inner cutter 1 is covered with the flocked part 6 of the outer cutter 2, and the plain part 5 of the outer cutter 2 is exposed to the outside to serve as a protective cover. By reciprocating the inner cutter 1, the hair from the inner cutter 1 can be sieved off by sliding into contact with the flocked portion 6.

As described above, the present invention provides a group of blade holes in approximately half of the outer cutter in the curved direction, and also forms a flocked portion on the inner surface of the uncoated portion of the other approximately half of the outer cutter, and extends the outer cutter along the inner cutter. Since it is attached to the razor body so that it can slide freely in the curved direction, when in use the inner blade is covered with the hole group of the outer blade and the inner blade is driven back and forth, the shaver can be shaved, and when not in use it is possible to shave. In this case, slide the outer cutter to cover the inner cutter with the plain part of the outer cutter.The plain part acts as a protective cover, and if you drive the inner cutter in this state, the inner cutter will slide into contact with the flocked part and cover the inner cutter. This has the effect of being able to sift off the beard debris from the blade and saving the effort of cleaning the inner blade each time with a brush.
