Blade with a new profile

By incorporating a novel toothed design with a grooved structure on the blade surface and a smooth transition between sharp-angled edges, the problems of existing blade jamming and low cutting efficiency are solved, resulting in a more efficient and durable hair cutting effect.

AI Technical Summary

Technical Problem

The toothed structure design of existing hair cutting blades leads to jamming, low cutting efficiency, difficulty in quickly cutting coarse and hard hair, and insufficient rigidity of the blade teeth, which makes them prone to deformation and affects their service life.

Method used

A novel tooth structure is designed, with a grooved structure on the cutting edge section. The grooved structure extends to the cutting surface to form a notch. The acute-angled cutting edge and the flat cutting edge are seamlessly connected. The layered design of the cutting teeth optimizes stress distribution and chip removal performance.

Benefits of technology

It improves the smoothness and efficiency of hair cutting, extends the service life of the blades, enhances chip removal performance, and reduces cutting resistance and the risk of blade deformation.

Abstract

A kind of blade with new tooth shape structure, groove structure is arranged on the blade edge section surface, compared with the prior art, corresponding groove structure is arranged on the side surface of the whole cutter tooth, the design only sets up groove structure on the blade edge section surface, can reduce the influence on the overall strength of cutter tooth while ensuring the sharpness of cutter tooth.Because the prior art sets up groove structure on the side surface of the whole cutter tooth, the strength of cutter tooth can be greatly weakened, and problems such as cutter tooth fracture are prone to occur during use.The groove structure of the design extends to the cutting surface to form a notch, which can further optimize the cutting effect.
