The electric shaver uses a motor to drive the moving blade to move relative to the fixed blade to cut the beard or hair that enters the mesh.
The shaving effect of an electric shaver is mainly determined by the accuracy of the anastomosis between the fixed blade and the movable blade. It requires that the spherical curvature of the fixed blade and the movable blade be matched properly, and at the same time, there must be a pressure distance of about 1mm and a certain shear angle between the two blades. If the pressing distance is too small, the shave will not be sharp, and there will be a feeling of plucking; if the pressing distance is too large, the power consumption will be large, the blade will be severely worn, and a sharp abnormal cry will be emitted.
The fixed knife adopts a net shape. Different manufacturers have different mesh patterns, but they can keep the fixed blade and movable blade at a certain cutting angle, and can make the hair entry rate high. The production process of the fixed blade is different, and its use effect is also different. The fixed blade adopts stamping, corrosion, and re-stamping processing technology, its blade sharpness is poor, the skin feel is average, the texture changes are few, the lines are rough, and the service life is not very long. The fixed blade adopts electroforming, stretch grinding, stamping and milling processing technology, the blade has good sharpness, comfortable skin feel, fine lines, and long service life.
The movable blades are evenly distributed on the movable blade holder, and the movable blade holder is required to have no obvious radial runout, which can maintain the rotating balance of the movable blade holder, and is matched with the corresponding speed to make the relative movement between the fixed blade and the movable blade in a shave The best condition of the beard, so that no matter the number of moving blades, you can achieve the purpose of sharp shave.
