AI Technical Summary
When trimming nose hair, existing nose hair trimmers are prone to hair pulling due to uneven force, and the sharpness is insufficient, which affects the user experience; due to the difference in user usage, the manual nose hair knife leads to unstable rotation speed and shearing force of the drill blade, which affects the sharpness and stability of the blade head.
A nose hair knife head is designed, using a fixed knife and a movable knife with an annular structure. The movable knife maintains center movement within the fixed knife through an elastic stabilization component. The blade of the movable knife is set in an inclined manner, forming a non-parallel position relationship with the fixed knife during shearing, reducing the phenomenon of jamming, and improving the coordination stability of the movable knife and the fixed knife through a hard knife tooth design similar to the haircutter.
Through elastic stabilization components, the movable knife rotates in the center within the fixed knife, reducing the hair pulling phenomenon, improving the sharpness and life of the knife head, reducing the temperature rise during friction of the knife head, and improving the user experience.

Abstract
Description
[Technical field]
[0001] The utility model relates to a nose hair cutter head. [Background Technology]
[0002] The electric nose hair trimmers on the market now generally use the traditional structure of a spring-loaded thin blade as the moving blade. When trimming nose hair, the mutual movement between the rotating elastic thin blade and the inner wall of the fixed blade is likely to produce uneven force, causing hair pulling. At the same time, the lack of sharpness leads to overall skin discomfort during trimming, which gives the user a bad experience. Although the manual nose hair trimmers on the market have optimized the structure of the moving blade with thick blades and improved the sharpness of the blade itself, the difference in the user's use force during the pressing process of the manual device will cause differences in the rotating speed and shearing force of the moving blade, thereby affecting the sharpness and stability of the blade head, and ultimately greatly reducing the user's comfort when using the manual rotating nose hair trimmer. As for the thick blade upgrade to an electric nose hair trimmer, the current technical process cannot effectively solve the product temperature rise caused by the structural matching problem between the fixed blade and the moving blade. The smoothness of the blade head sliding then affects the user experience and product stability, and the process cost is also high. [Contents of the utility model]
