Definitions

  • the present invention relates to an electric shaver structure, and more particularly to an outer blade of an oscillating electric shaver.
  • the basic principle of an electric shaver is to provide a blade set that swings or rotates left and right under a net cover. When the net cover is attached to the skin, the hair extends from the through hole of the net cover and is cut by the blade.
  • the mesh cover is also referred to as an outer knife, and the blade set below the mesh cover is referred to as an inner knife.
  • Chinese patent 200720008255.8 discloses 'one An outer blade structure of a reciprocating electric shaver, the outer blade being bent by a thin plate and having an elongated shape, laterally distributed on the head of the razor, having a top surface and a side surface, the top surface including the reinforcing portions at both ends and the middle portion
  • the blade portion whose thickness is thinned has a plurality of long slit holes formed in the blade portion of the top surface to form a cutting edge.
  • the structure mainly utilizes the reinforcing portions at the two ends of the side and the top surface to support the surface, and the portion of the intermediate thickness is used to form the cutting edge, and the disadvantage is that the portion with the thinner intermediate thickness is more difficult to process, and the processing process is relatively high. .
  • the invention provides an outer knife of a swing type electric shaver, and the main purpose thereof is to overcome the disadvantages of the outer cutter of the prior art electric shaver being difficult to process and the processing cost is high.
  • an outer blade of an oscillating electric shaver includes a main body, the main body is bent from a thin plate, and has a top surface, two front and rear sides, and a plurality of knives arranged on the top surface.
  • the hole, the side edge of each knife hole forms a cutting edge, and the top surface is provided with reinforcing ribs formed by pressing at positions near the left and right ends, respectively.
  • the reinforcing ribs are upwardly convex.
  • the reinforcing ribs can also be recessed downward.
  • the outer blade of the oscillating electric shaver is provided with a left-right running groove on the top surface thereof, and two knife hole distribution areas are formed on the front and rear sides of the groove, and the knife holes are distributed in the knife hole distribution.
  • the ribs are distributed at both ends of each knife hole distribution area.
  • the thickness of the knife hole distribution area is smaller than the thickness of other portions.
  • the cross section of the top surface is an upward convex arc shape.

  • FIG. 3 is a schematic perspective view of a first embodiment of the present invention.
  • An outer blade of an oscillating electric shaver includes a main body 10 which is bent from a thin plate and has a top surface 1 and a front side surface 2, a rear side surface 3, and the top surface 1 is provided with left and right sides.
  • the groove 11 is formed, and the front and rear sides of the groove 11 form two elongated blade-shaped distribution areas 12 and 13, and each of the knife-hole distribution areas 12 and 13 is respectively provided with a plurality of knife holes 120 and 130.
  • the side edges of the respective cutter holes 120, 130 form a cutting edge.
  • Reinforcing ribs 41 and 43, 42 and 44 are provided at the left and right ends of each of the knife hole distribution regions 12, 13.
  • Each of the reinforcing ribs 41, 42, 43, 44 is formed by punching the top surface 1. Taking the reinforcing rib 41 as an example, referring to FIG. 2, the reinforcing rib 41 is partially raised upward from the upper surface of the top surface 1, and the corresponding position of the lower surface is upward. The recess is formed, and the rib 41 is an upwardly convex structure as viewed from the outside.
  • the thickness of the knife hole distribution regions 12, 13 is smaller than the thickness of the other portions.
  • the structure and principle of the present embodiment are basically the same as those of the first embodiment.

Abstract

Une lame extérieure d'un rasoir électrique de type à mouvement de va-et-vient comprend un corps principal (10). Le corps principal (10) est formé en pliant une feuille mince et comprend une surface supérieure (1) et deux surfaces latérales à l'avant et à l'arrière (2,3). Plusieurs trous de lame (120,130) sont disposés sur la surface supérieure (1). Le bord de chaque trou de lame est façonné de façon à former un bord de couteau. Des nervures de renfort (41-44) formées par poinçonnage sont respectivement réalisées près des extrémités gauche et droite de la surface supérieure (1). Les nervures de renfort formées par poinçonnage sont utilisées pour augmenter le soutien et le procédé de traitement des nervures de renfort est simple.
