Description

[Detailed Description of the Invention] This invention relates to an improvement in the outer blade pattern of a reciprocating electric razor.

The shapes of the hair introduction holes in the outer blade of conventional reciprocating electric razors include circular, oval, diamond, hexagonal, rectangular, oblong, etc. Patterns have the advantage of having a high aperture ratio, but they have the disadvantage of making it difficult to introduce long hairs, and patterns with continuous rectangular or oblong ellipses make it easy to introduce long hairs, but it is difficult to introduce long hairs. The disadvantage is that it is unsuitable for shaving long hair because it has a directional pattern.

In view of these points, the present invention forms radial ribs having an angle of 120 degrees to each other on a thin metal plate, and arranges circular whisker introduction holes at the apex of each rib, and trapezoidal whisker introduction holes in each rib. The drawbacks of the conventional method have been solved by continuously forming a group of trapezoidal hair introduction holes in which oppositely oriented trapezoidal hair introduction holes are formed so as to face each other and are arranged opposite to the long sides of the respective trapezoidal hair introduction holes.

The present invention will be explained below based on the illustrated embodiments. Trapezoidal beard introduction holes c, c, and c are arranged opposite to each rib a, and opposite trapezoidal beard introduction holes c', c', and c' are provided to face the long sides of each trapezoidal beard introduction hole C. The outer cutter E is constructed by consecutively arranging the respective groups of hair introduction holes.

d designates mounting holes provided on both sides of the thin metal plate A in the longitudinal direction.

Figure 3 shows a hexagonal beard introduction hole b instead of a circular beard introduction hole.
This is a different embodiment in which .

As mentioned above, in this invention, the trapezoidal beard introduction holes C and C' are oriented in three directions, so that it is possible to capture beards in various directions. The beard can be efficiently introduced by trapping it in the introduction hole, and the rib width can be kept constant, resulting in a high aperture ratio and the effect that the beard can be shaved with high speech.
