An integrated multi-rotating blade 100 having the function of depilating the skin of the present invention comprises a blade support 110 and a blade 120.

Hereinafter, each component constituting the integral multi-rotary blade 100 will be described in detail.

The blade support 110 is configured in a ring shape and may be configured in one ring shape or two ring shapes as in one embodiment of Figures 1 and 3, but is not limited thereto.

When the blade supporting portion 110 is formed in two or more ring shapes, the two or more rings are each provided with a concentric circular shape in which the diameters thereof are different from each other, do.

The blade unit 120 is mounted on the blade support 110 and is supported by the blade support 110 described above. When viewed from the side of the integrated multi-rotation blade 100 of the present invention, the blade supporting portion 110 and the blade portion 120 are integrated to form a portion where the blade portion 120 is supported by the blade supporting portion 110 And FIG. 5 shows a blade member 120 that is not supported by the blade support 110. Referring to FIG. Since the blade support 110 is not a disk but a ring, it does not support all the parts of the blade 120, so that the blade 120, which is not supported by the blade support 110 as shown in FIG. 5, A blade support 110 having an appropriate number of rings should be formed to provide strength.

The razor blade unit 120 includes a plurality of razor blades, each of which forms a tilt at a predetermined angle in the rotational direction, as shown in Figs. 4 and 5, 0.0 > 110 < / RTI >

4 and 5, each of the plurality of blades includes a surface contact portion 121 that is in surface contact with the skin as shown in FIGS. 1, 2, 4 and 5, and the surface contact portion 121 Has a blade angle (A) of 90 degrees or less as a reference, and has a blade thickness (T) which is the thickness of each of the plurality of blades. In addition, a blade gap W between each of the plurality of blades exists between the blades.

When the blade interval W between the blades is wide, it means that the number of blades of the integrated multi-rotation blade 100 is small. Therefore, when the number of blades is small, the blade interval W is widened, However, it is not limited to this method.

The blade intervals W between the plurality of blades may be the same or may be different from each other. For example, the blade section 120 may be formed by widening and narrowing the blade gap W so that when viewed from above, the blade section 120 is separated from the first blade, the first blade, by 60 degrees A third blades spaced 30 degrees from the second blades, a fourth blades spaced 60 degrees from the third blades, a fifth blades spaced 30 degrees from the fourth blades, a second blades spaced 60 degrees from the fifth blades, A sixth blade which is spaced by 30 degrees from the sixth blade and a sixth blade which is spaced apart from the sixth blade by a distance of 60 degrees from the sixth blade, When the two razor blades are separated by 60 degrees, the next blades are separated by 60 degrees. By changing the hair removal area at this moment, the skin irritation can be reduced.

The blade thickness T of each of the plurality of blades may be the same or may be different from each other. For example, four razor blades having thick blade thicknesses (T) at intervals of 90 degrees are provided, and a plurality of blades having thin blade thicknesses (T) are provided between the respective thick blades, and thick blades Can be removed, and a thin razor blade can be used to remove secondary hair.

The blade supporting portion 110 and the blade portion 120 are integrally formed of a ceramic material and rotate in one direction by a predetermined rotary power means.

Since a plurality of razor blades constituting the blade section 120 are made of ceramic, they have good affinity with the skin and have no problem of oxidization, abrasion, contamination, and the like, which are problems of conventional metal razor blades. can do. In addition, although the conventional rotary shaver requires a protective net, the present invention enables safe shaving without a protective net because the blade is in surface contact with the skin and the material of the blade is ceramic.

In addition, since the blade supporting portion 110 and the blade portion 120 are integrally manufactured, there is no difference in height or separation distance of the blade, and various defects in the existing methods of manufacturing and assembling the components of the razor There is no danger.

A plurality of razor blades constituting the blade section 120 are connected to predetermined power means such as an electric motor and rotated in one direction to enable shaving, wherein the rotating direction is the oblique direction of the razor blade 4).
