Description

[Detailed description of the invention] The present invention relates to the structure of a rotary electric razor.

Conventionally, there have already been rotary electric razors in which an inner blade for shaving beards is in sliding contact with an outer blade under a constant pressure. However, in such conventional electric razors, when the outer blade is pressed against the skin surface with strong pressure, the skin excessively protrudes from the hair introduction hole of the outer blade, and the skin is scraped by the blade surface of the inner blade, resulting in excessive There was an issue that was irritating.

The present invention has been made in view of the problems of the prior art, and is intended to improve these drawbacks.

An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a sectional view of an embodiment of the rotary electric razor of the present invention;
FIG. 2 is a sectional view of the shaving state, and FIG. 3 is a perspective view of the inner cutter.

In the figure, reference numeral 1 denotes an outer cutter having a substantially spherical shell shape and having a plurality of hair introduction holes la. 2 is an outer cutter frame, 3 is a main body, and 4 is a motor.

Reference numeral 5 denotes an inner cutter, which is formed by punching a thin metal plate, and the vicinity of the blade surface is curved at a slight angle.

Reference numeral 6 denotes an inner cutter stand equipped with a plurality of inner cutters 5, which is connected to the motor 4.

A comb-shaped spring 7 is formed by bending a thin metal plate and has a substantially C-shaped cross section projecting from the base 7a.

That is, a horizontal part 7b is provided protruding from the base part 7a in the direction of the grain, and further, a mirror inclined part 7d is extended through the vertical part 7c, and a top part 7e is formed at the upper end thereof. Folded piece 7 further from top 7e
f is extended. The comb-shaped spring 7 formed in this manner has its base 7a attached to the front side in the moving direction of the inner cutter 5,
The top portion 7e is close to the blade surface 5a.

Therefore, the folded piece 7f is close enough to slide on the back surface of the blade surface 5a. Next, a method of using the rotary electric razor of the present invention will be described.

As shown in FIG. 2, the blade surface 5a of the inner cutter 5 is in sliding contact with the inner surface of the outer cutter 1, and the top portion 7e of the comb-like spring 7 is provided in sliding contact with the inner surface of the outer cutter 1. Now, when the inner cutter base 6 is rotated by the drive of the motor 4 and the inner cutter 5 moves in the direction of the arrow, the beard introduction of the outer cutter 1 is performed because the forehead oblique portion 7d and the top portion 7e are each formed in a comb shape. The skin excessively protruding inward from the hole la is pushed upward by the top 7e, and only the beard is inserted between the oblique part 7d and the top 7e and shaved by the blade surface 5a of the inner cutter 5.

Therefore, the skin that protrudes inward from the beard introduction hole la is not shaved by the blade surface 5a of the inner cutter 5, so that the user does not feel discomfort due to excessive stimulation of shaving. As described above, the rotary electric razor of the present invention is equipped with a comb-shaped spring having a substantially C-shaped cross section, and the top near the free end of the comb spring is disposed close to the blade surface of the inner cutter. It is possible to push back the skin that protrudes inwardly to the outside, thereby solving the inconvenience of the blade surface of the inner blade being scraped due to excessive protrusion of the skin, and thus having the effect of preventing excessive irritation caused by shaving.
