Inner cutter head of rotary electric shaver

Abstract

The invention discloses an inner cutter head of a rotary electric shaver, which has simple processing and can realize a double-layer double-row or double-layer multi-row cutting edge structure. The inner cutter head comprises an inner cutter seat, wherein a plurality of groups of cutting edge devices which are uniformly distributed in the circumferential direction are arranged on the inner cutterseat, each group of cutting edge devices comprises a thick cutter blade and a thin cutter blade, one end of the thick cutter blade is provided with at least one row of inwards inclined cutting cutterheads, the end part of each cutting cutter head is provided with a cutting edge, the other end of the thick cutter blade is fixedly connected with the inner cutter seat, one end of the thin cutter blade is provided with hair pulling cutter heads corresponding to the number of the cutting cutter heads, the end parts of the hair pulling cutter heads are learned at the inner side of the end parts ofthe cutting cutter heads, the end parts of the hair pulling cutter heads are provided with contact cutting edges, the other end of the thin cutter blade is fixedly connected with the fixed end of thethick cutter blade, and a movable gap is formed between the thick cutter blade and one end of the thin cutter blade provided with the hair pulling cutter heads.

Description

technical field [0001] The invention relates to an inner cutter head of a rotary electric shaver. Background technique [0002] The Chinese Invention Patent No. ZL01801355.4 issued on November 24, 2004 discloses an inner cutter head of a rotary electric shaver with a double-layer structure. The inner cutter head includes an inner shearing part and a hair pulling part. , the inner shearing part is provided with a plurality of cutting parts with cutting edges, the pulling part is provided with a plurality of blade-shaped pulling elements, and each cutting part has a blade-shaped pulling element such as being in the frontmost position in the driving direction, And the hair pulling element moves relative to the corresponding cutting element along the direction away from or towards the ring wall portion of the outer shearing member during the working process of the shaving device, and each hair pulling element has a thickened end with a blade, which can be used during shaving Du...

Problems solved by technology

[0005] The beneficial effect of the inner cutter head of the rotary electric shaver of the present invention is that: since the inner cutter seat is provided with multiple groups of blade devices, each group of blade devices is respectively provided with a thick blade and a thin blade, and a single thin blade is matched with a single thick blade. The setting greatly simplifies the processing of thin blades, and at the same time, a single thin blade and a single thick blade are also easy to fit together, which overcomes the difficulty in attaching each blade-shaped hair pulling element to the corresponding cutting piece in the prior art Due to the matching setting of a single thin blade and a single thick blade, when the thick blade is equipped with double-row cutting heads or multi-row cutting heads, as long as the thin blade is also equipped with double-row pulling heads or multi-row pulling heads Matched with thick blades, the inner cutter head of the rotary electric shaver with double-layer double-row or double-layer multi-row blade structure can be realized, and even the inner head of the rotary electric shaver with multi-layer multi-row blade structure can be realized. knife head
