Mainly relying on the built-in micro motor to drive the operation of the cutting head. After the motor is powered on, it converts electrical energy into mechanical energy, driving the cutting head to rotate or reciprocate at high speed. There is usually a fine metal mesh cover on the outside of the blade, through which nose hair enters the working area of the blade and is cut by the blade, thus achieving the function of nose hair trimming.
Advantages: Convenient and fast, easy to operate, can quickly trim nose hair. Relatively safe, the blade design takes into account the characteristics of the nasal cavity and is less likely to damage the nasal mucosa. Some products have low noise levels, do not cause interference during use, and are mostly designed to be waterproof, making them easy to clean.
