The electric razor uses the motor to move the moving blade relative against the fixed blade, cutting the beard or hair into the mesh.
The quality of the shaving effect is mainly determined by the matching accuracy between the fixed blade and the moving blade. It requires that the spherical radian of the fixed blade and the moving blade should be properly matched, and there should be about 1mm pressure distance and a certain shear Angle between the two blades. The pressure distance is too small, the shaving is not sharp, and if the pressure distance is too large, the power consumption and the blade is seriously worn, and the sharp abnormal call.
The fixed knife is made of a mesh. Different manufacturers have different mesh pattern, but they can make the fixed blade, moving the blade to maintain a certain shear Angle, and can make the hair entry rate is high. The production process of fixed blade is different, its use effect is also different. Using stamping, corrosion, restamping processing process of the fixed blade, its blade sharpness is poor, the skin feeling is general, the mesh pattern changes less, rough lines, the service life is not very long. And the use of electric casting, tensile grinding, stamping and milling processing process of the fixed blade, good blade sharpness, comfortable skin feeling, fine lines, long service life.
The moving blade is evenly distributed on the moving blade frame, and requires that the moving blade has no obvious diameter beating, can maintain the rotation balance of the moving knife frame, coupled with the corresponding speed, the relative motion between the fixed blade and the moving blade is in the best state of shaving, so that no matter the number of moving blade, can achieve the purpose of sharp shaving.
At present, there are mainly two kinds of shaving systems used in electric whiskers: mesh type and rotary type. From the principle of movement, the former is through the knife head reciprocating movement, shaving beard, due to the knife head in the reciprocating movement of speed, deceleration, use of vibration and noise; rotating shaving system is a central rotation operation, circular movement can continuously one-way shaving beard, not only make the shaving more clean and thorough, not to beard pulling and discomfort, and use quiet without vibration, shaving more comfortable. In addition, whether the electric beard knife has floating knife head, paste surface adjustment and other functions should also be paid attention to when choosing.
