【考案の詳細な説明】
本考案は多数のくし状の切刃を形威した固定刃と可動刃
とからなる電気かみそり刃に関するものである。[Detailed Description of the Invention] The present invention relates to an electric razor blade consisting of a fixed blade and a movable blade in the form of a large number of comb-shaped cutting blades.
従来の電気かみそり刃は、固定刃の切刃と可動刃の切刃
の全面が接触するようになっており、接触面積が広いた

そりにあっては短時間で電池容量がなくなるという問題
点があった。In conventional electric razor blades, the fixed cutting blade and the movable cutting blade are in contact with each other on their entire surface, and the contact area is large, resulting in a large sliding load. However, there was a problem in that the battery capacity ran out in a short period of time.
本考案は上記の問題点に鑑みて提供したものであって、
固定刃と可動刃との摺動負荷が低い電気かみそり刃を提
供することにある。This invention was proposed in view of the above problems,
To provide an electric razor blade with low sliding load between a fixed blade and a movable blade.
以下本考案の一実施例を図面を参照して説明する。An embodiment of the present invention will be described below with reference to the drawings.

It comes into contact with the cutting edge 5 of the movable blade 4.

くひけ剃り作業を行うことができるという効果がある。As described above, the electric shaver blade according to the present invention has a fixed blade that has many notches on its edge to form many comb-shaped cutting edges, and a fixed blade that has many notches on its edge to form many comb-shaped cutting edges. In an electric shaver blade, which consists of a movable blade and a movable blade, in which the movable blade reciprocates on the fixed blade cutting blade, a continuous blade of approximately the same width is formed along the entire circumference of the fixed blade cutting blade. The feature is that a raised platform is formed on the sliding surface of the movable blade, so compared to conventional electric shaver blades, the contact area between the fixed blade and the movable blade is reduced, and the area of contact per unit area is reduced. This has the effect of increasing the contact pressure, improving the cutting quality, reducing the sliding load, and improving the battery life for electric shavers that use batteries as a power source. Since the raised base 3 is provided, edges are formed only on both sides of the tip of the cutting blade, and these edges can be eliminated by the same processing as conventional fixed blades that are not provided with the raised base. This has the effect of not damaging the skin, and furthermore, dirt and small shavings on the sliding surfaces of the fixed blade and movable blade are blocked by the raised table and discharged from the tip of the cutting blade of the fixed blade. Since the shaving process is hygienic and comfortable, the shaving process can be carried out comfortably.
