Abstract

Disclosed in the invention is an outer blade of a reciprocating electric shaver with reinforcing structure, which is formed by bending a sheet and providedwith a top face (1), a front side face (2) and a back side face (3). The top face is a curved surface which is protruded upwards. The front and back sides of the top face are staggered inwards relative to the front and back side faces, so that an inclined face (51, 52) which is inclined from inner upside to outer downside or a flat face is formed at the connecting position. The top face forms a shaving work face by processing the inner side, wherein the thickness of the shaving work face is less than that of the front and back side faces. Multiple blade holes (14) are arrayed in the shaving work face, and the side edge of each blade hole forms a blade edge. The thickness of the top face of the outer blade of the electric shaver is consistent, so the outer blade is easy to be processed. Although the thickness of the top face is less than that of the front and back side faces, the structure of the top face and the connection structures of the top face and the front and back side faces enable the top face with high intensity.

BEST MODE FOR CARRYING OUT THE INVENTION

An outer cutter of a reciprocating electric shaver having a reinforcing structure, referring to Figs. 1 and 2, includes a main body 10 which is bent from a thin plate and has a top surface 1 and a front side 2 and a rear side 3. The top surface 1 is an upwardly convex curved surface, and may be a semi-cylindrical surface, or may be a semi-elliptical cylindrical surface or other smooth curved surface, and the front and rear side edges of the top surface are opposite to the front side 2 The rear side faces 3 are offset inwardly, and

inclined faces

51, 52 which are inclined from the inner upper side to the outer lower side are respectively formed at the joints. The top surface 1 is formed by inner processing to form a shaving working surface having a thickness smaller than the front side surface 2 and the rear side surface 3. The inclined surface 51 is formed by connecting two

cylindrical surfaces

511, 512 parallel to the center line, wherein the cylindrical surface 511 connected to the top surface 1 is concave inward, and the cylindrical surface 512 connected to the front side 2 is convex outward; the inclined surface 52 is also connected by two

cylindrical surfaces

521, 522 which are parallel to the center line, wherein the cylindrical surface 521 connected to the top surface 1 is concave inward, and the cylindrical surface 522 connected to the rear side 3 is convex outward.

Referring to FIG. 1 , the top surface 1 is provided with a left and right groove 11 , and the front and rear sides of the groove 11 form two elongated blade

hole distribution regions
