Description

[Detailed Description of the Invention] This invention relates to an improvement of a rotary dry razor for shaving using an outer cutter and an inner cutter that rotates and slides into contact with the inner surface of the outer cutter.

In conventional razors of this type, hairs adhering to the inner blade etc. are removed using a brush after use, but in this case it has been impossible to remove fat and body odor at the same time.

In addition, with conventional products, in order to know the amount of hair inside the outer blade holder, it is necessary to remove the outer blade holder from the razor body, which is troublesome. When it was removed, whiskers would scatter around.

Furthermore, as seen in Japanese Utility Model Publication No. 43-29806, the inner blade storage part housed in the outer blade body communicates with the outside through a communication hole so that the inside can be washed with water. During cleaning, the inner blade rotates with the outer blade in sliding contact with the inner blade, which places a large load on the motor during cleaning, and since rotation is suppressed, it is difficult to generate an effective water flow, resulting in a low cleaning effect. there were.

This idea was devised based on the above-mentioned circumstances, and its purpose is to make it possible to check the amount of shaved hair without removing the outer blade holder, and to make it possible to wash with water very effectively. The object of the present invention is to obtain a rotary dry type razor which eliminates the disadvantages of the conventional type.

This invention will be described below with reference to an embodiment shown in the drawings.

In the figure, reference numeral 1 denotes a razor body made of synthetic resin, etc., on which a cylindrical sink space forming wall 2 is integrally protruded, and a rotating shaft insertion portion 3 is located approximately in the center of this forming wall 2. is prominent.

The inner space of the beard pool space forming wall 2 serves as a beard pool 4, and the beard pool space forming wall 2 has a discharge portion, for example, a through hole 5 formed of a long hole, which communicates with the beard pool 4. ing.

Further, an inner blade drive device, for example, an electric motor 6 is housed in the razor body 1, and its rotating shaft 7 is connected to the rotating shaft insertion portion 3.
penetrates through.

A sealing material 8 such as an O-ring is installed inside the rotary shaft insertion portion 3, and a watertight structure is formed between the rotation shaft insertion portion 3 and the rotation shaft 7.

An inner cutter stand 10 having a plurality of inner cutters 9 attached thereto is supported at the tip of the rotating shaft 7 so as to rotate together with the rotating shaft 7.

The inner cutter stand 10 can be removed from the rotating shaft 7 by pulling strongly if necessary, and is supported so that it will not come off the rotating shaft 7 even if it is turned upside down.

Furthermore, a plurality of stirring parts 11 are integrally provided on the back surface of the inner cutter stand 10 facing the whisker storage space 4, and this embodiment shows a case where the stirring parts 11 are formed as blades.

In addition, 12 in the figure is an opening/closing mechanism which is movably movable in the axial direction on the beard storage space forming wall 2, and opens and closes the ejection part by its movement, and also moves the outer cutter, which will be described later, toward and away from the inner cutter 9. be.

In this embodiment, this opening/closing mechanism 12 also serves as an outer cutter holder, and is a cylindrical body made of metal or the like. A blade 14 is attached to the other end, and a through hole 5 serving as the discharge section is provided at the other end.
A through hole 15 made of a long hole that can be freely communicated is bored in the.

The opening/closing mechanism 12 is removably mounted on the razor main body 1 by threading a threaded groove carved on its inner surface into a threaded groove on the outer surface of the beard storage space forming wall 2.
2 is screwed in to the end (that is, in normal use), the through holes 5 and 15 are in a non-communicating closed state.

In this electric shaver, by driving the electric motor 6 in the state shown in FIG. The introduced beard can be shaved, and the shaved beard is accommodated in the beard reservoir 4.

By the way, in order to know how much beard has accumulated in the beard reservoir 4 after use, etc., first rotate the opening/closing mechanism 12 slightly in the direction of removing it from the razor body 1 to make the through holes 5 and 15 communicate (open). If a large amount of
The shaved beard is pushed out through the holes 5,15.

The degree of hair accumulation can be checked by whether or not the shaved hair comes out through the through holes 5 and 15. Therefore, it is possible to check the timing of cleaning and whether it is okay to roughly remove the outer cutter holder that spans the opening/closing mechanism 1. You can easily know whether the outer blade holder is the same or not without removing the outer blade holder.

In addition, when washing this electric shaver with water to clean it, the opening/closing mechanism of the electric shaver is turned upside down with the through holes 5 and 15 communicating with each other as shown in FIG. 12 is preferably immersed in washing water containing detergent, and the inner cutter stand 10 is rotated.

Then, a stirring water flow is formed by the inner cutter 9 and the stirring part 11, so that the cleaning water flows through the small hole of the outer cutter 14 as shown by the arrow in FIG. 2 and is effectively stirred. , 15 to the outside.

Therefore, the liquid-contacting part is washed with water by such a water flow, and thereby not only beards adhering to the liquid-contacting part, but also fat, body odor, etc. can be removed.

In this case, the stirring water flow is generated not only by the inner cutter 9 but also by the stirring part 12, but since this stirring part 12 faces the beard storage space 4, it can effectively and effectively stir the beards stored in this space 4. It can be forcibly blown up, making it extremely useful for discharging whiskers and the like along with the agitating water stream.

Furthermore, by moving the opening/closing mechanism 12, the outer blade 1 can be
4 is separated from the inner cutter 9, the load on the inner cutter drive device can be reduced.

Therefore, the rotation of the inner cutter 9 during washing with water becomes smooth, and a strong stirring water flow can be obtained.

In the case of this embodiment, since the opening/closing mechanism 12 is of a screw-in type, the communicating area of the elongated holes 5 and 15 can be adjusted, and thus the flushing effect can be changed by this adjustment.

Note that this invention is not limited to electric shavers, but can also be implemented in devices equipped with various mechanical inner cutter drive devices that obtain driving force for the inner cutters using a spring force such as a spring.

In addition, when implementing this invention, unless it is contrary to the gist of the invention, the razor body, inner blade drive device, beard storage space,
Hair storage space forming wall, discharge section, opening/closing mechanism, outer cutter inner cutter stand,
The specific structure, shape, position, etc. of the inner blade and stirring part are as follows.
It goes without saying that the present invention is not limited to the above embodiment and can be implemented in various configurations.

Since this invention explained above has the structure described in the above-mentioned utility model registration claim, by moving the opening/closing mechanism and opening the ejection part, it is possible to check the accumulation of shaved hair without removing the outer blade holder. You can know.

Then, the opening/closing mechanism separates the outer cutter from the inner cutter, opens the discharge section, and drives the inner cutter drive device while introducing water into the beard storage space, thereby causing the inner cutter and the stirring section to stir and supply water. The load on the inner cutter drive device is reduced, the inner cutter stand is rotated smoothly, an effective water flow is generated, and the water in the sink space can be drained from the discharge part.

Therefore, it can be washed with water very effectively, which has the effect of easily removing fat, body odor, etc.
