Description

[Detailed description of the invention] This invention relates to a reciprocating electric shaver.

In general, a reciprocating electric shaver has a main body 1 equipped with a switch 2 as shown in FIG.
By reciprocatingly sliding the inner cutter inscribed in the outer cutter, the whiskers introduced into the outer cutter hole are cut.

However, since the radius of curvature of this reticulated outer cutter 3 is constant, there are the following problems.

That is, the larger the diameter of the planar part of the '1' face, the larger the contact area with the skin and the faster shaving, but the smaller the diameter, the longer it will take to shave.

2: If the diameter is large in the area of the lower jaw, it will be difficult to shave, but if the diameter is small, it will be easier to shave.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a reciprocating electric shaver that enables speedy shaving regardless of the area to be shaved.

An embodiment of the invention is shown in FIGS. 2 to 4.

That is, this reciprocating electric shaver is similar to the one shown in Fig. 1 in that the razor body is provided with a storage battery, a motor, a switch, and a reciprocating converter, and an inner blade holder 5 is attached to the output shaft 4 of the converter. A plurality of inner cutter assemblies 6 to 8 are provided in parallel in the lateral direction on the inner cutter holder 5 by reciprocating motion. The inner cutter assemblies 6 to 8 each have the same configuration, and have a number of grooves formed at regular intervals in the holding rod 9, and an inner cutter plate 10 in each groove.
- is fixed, and support legs 11 are attached to the lower surface of the holding birch 9. The coil springs 12 are passed through the support legs 11 of these three sets of inner cutter assemblies, passed through the mounting holes 13 formed on the upper surface of the inner cutter holder 5, and the retaining collars 1 provided at the tips of the support legs 11 are inserted.
4 to prevent it from coming out. In addition, in this state, the inner cutter plates 10 and 3 of the inner cutter assemblies 6 to 8 arranged in the horizontal direction of the inner cutter holder 5 are
... are mistaken for each other in a staggered manner. On the other hand, an outer blade holder 15 is attached to the upper peripheral edge of the razor body.

This outer cutter holder 15 has an outer cutter mounting recess 16 formed on the negative side piece, a thumbscrew 17 inserted through the center of the other side piece and prevented from coming out with a retaining ring 18, and both end pieces of the outer cutter holder 15 A laterally elongated recess 19 is formed at a position close to the other side piece on the inner surface. The silk-like outer cutter 20 has a locking part 21 formed at one end, a guide rod 22 fixed at the other end, and a screw hole 23 formed in the center of the guide bar 22.
, and both ends protrude beyond the silk-like outer cutter 20. The locking portion 21 of this silk-like outer cutter 20 is attached to the outer cutter holder 1.
Both ends of the guide rod 22 are slidably inserted into the horizontally elongated recess 19 by being locked in the mounting recess 16 of No. 5 and bent by its own spring property. Also, screw the thumbscrew 17 into the screw hole 23. When the outer cutter holder 15 is attached to the razor body in this way, the inner cutter plate 10 is inscribed in the outer cutter 20 and comes into elastic contact with the spring 12. therefore,
The operation of this reciprocating electric shaver is such that when the switch is turned on and the inner cutter plate 10 is reciprocated, and the hair is introduced from the outer cutter hole, the outer cutter 20 and the cutting edge of the inner cutter plate 10 work together to create the hair. is disconnected.

On the other hand, if you want to change the radius of curvature of the outer cutter 20, turn the thumbscrew 17 to the right and the guide rod 22 will slide in the horizontally long recess 19 and approach one side of the outer cutter holder 15, so the radius of curvature will become larger. When the thumbscrew 17 is turned to the left, the guide rod 22 moves away from one side, so the radius of curvature of the outer cutter becomes smaller, and the inner cutter assemblies 6 to 8 follow these changes. The spring 12 allows it to float and sink. As mentioned above,
Since the reciprocating electric shaver of the present invention changes the radius of curvature of the outer blade, the radius of curvature of the outer blade can be changed depending on the flat part or concave part of the area to be shaved, and the shaver can be shaved quickly. It has the effect of leaving no residue after shaving.
