An electric shaver

Abstract

An electric shaver in which a plurality of mutually separated cutter blades provided in an inner cutter are moved in relative terms while making sliding contact with an outer cutter that is formed with a plurality of hair introduction openings, so that hair that enters into the hair introduction openings of the outer cutter is cut by the cutter blades, wherein the cutter blades are caused to intersect the same hair introduction openings of the outer cutter at different angles.

Description

technical field [0001] The present invention relates to electric shavers, and more particularly to such electric shavers in which a plurality of spaced cutting blades of an inner cutter move relative to each other and are in sliding contact with an outer cutter having a plurality of openings to allow access to the outer cutter The hairs in the openings are severed by the cutting blade of the inner cutter. Background technique [0002] In an electric shaver comprising an outer cutter and an inner cutter, the inner cutter reciprocates (in reciprocating shavers) or rotates relative to a fixed outer cutter (in rotary or dome shavers). razor). A conventional inner cutting knife includes a plurality of cutting blades, as disclosed in Japanese Patent Application Laid-Open (Kokoku) Nos. S61-61829 and S57-53485, which have the same shape and are separated from each other. In these prior art inner cutting blades, a plurality of divided cutting blades intersect the opening (hair intr...

AI Technical Summary

Problems solved by technology

In fact, since the range b for cutting is limited, compared with the case where the entire periphery of the inner blade of each opening 14 is used for cutting, the wear of the cutting edge in the range b is accelerated so that the sharpness of the cutting edge get worse soon

In other words, the durability of the outer cutter becomes liable to decrease
