Problems solved by technology

However, the gap between the outer razor hole 44 and the outer razor 22 increases to a larger value, making it difficult to set the center position of the outer razor 22 due to looseness between the outer razor hole 44 and the outer razor 22.
Moreover, it also destabilizes the rotation of the inner razor 26
In addition, the outer cutter 22 tends to move considerably in the outer cutter hole 44, reducing shaving efficiency.

Embodiment Construction

[0029] Preferred embodiments of the electric rotary shaver of the present invention will be described below with reference to the accompanying drawings. The electric rotary shaver of the present invention is characterized by a method of supporting the outer shaver in the blade holder. Accordingly, the following description will primarily refer to the structure for supporting the outer razor in the cartridge.

[0030] The overall structure of the electric rotary shaver of the illustrated embodiment, the internal structure of the cutter head 20, and the structure of the driving mechanism of the inner shaver are the same as Figure 7 and 8 The same as that used in existing electric rotary shavers in . More specifically, the cutter head detachably mounted on the upper part of the main body housing is composed of a knife holder, an outer razor, an outer razor blade holder, an inner razor, an inner razor base supporting the inner razor, and a cutter fixing plate for rotatably insta...

Abstract

In an electric rotary shaver in which outer cutters are provided in outer cutter holes formed in a cutter frame so that the outer cutters can move in the axial direction and tilt in any desired direction with inner cutters disposed between the outer cutters and inner cutter drive shafts that are urged in the axial direction toward the outer cutter, the outer surfaces of the outer cutters and the inner surfaces of the outer cutter holes being caused to make a sliding contact so that the outer cutters tilt in any desired direction in the outer cutter holes. The circumference of each outer cutter is curved so as to snugly engage with the curved outer surface of each outer cutter hole.

Description

technical field [0001] The present invention relates to electric rotary shavers, and more particularly to a structure for supporting an outer shaver in a knife holder of an electric rotary razor. Background technique [0002] Figure 7 It is a three-dimensional view of the overall structure of an electric rotary shaver in the prior art. In the electric shaver 10 , the cutter head 20 is detachably mounted on the upper portion of the main body casing 12 of the shaver 10 . Three outer razors 22 are arranged in the cutter head 20 such that the centers of the outer razors are located at the vertices of an equilateral triangle. A plurality of slits for introducing beards are formed on the outer cutter 22 in the radial direction. Also, in each outer razor 22, a circular outer hair introduction region V and a circular inner hair introduction region W are formed in a concentric arrangement, and the boundary between the outer hair introduction region V and the inner hair introductio...
