What are the tips for buying electric clippers?

There are two types of electric clippers: electromagnetic oscillating clippers and electric clippers.

(1) Beautiful appearance, light weight, flexible operation, labor saving, small vibration and low noise.

(2) The blade has good hardness, the scissors have sharp edges, and the cutting is light and easy, without pulling or pinching.

(3) The movement fluctuation of the upper blade is not less than 1.5mm. The contact surface of the lower blade should be flat and lubricated. The blade should have various standards such as coarse, medium and fine.

(4) Electric clippers are operated by hand when used. It is an electric appliance that directly touches the human head. Therefore, the requirements for its electrical functions should be particularly strict. The insulation must be good and reliable, and there should be no leakage. At the same time, use it continuously for 8 minutes at full load, turn it off for 4 minutes, and use it continuously for 8 minutes. The temperature rise of the lower blade should not be higher than 15°C, and the temperature of the electromagnetic coil should not be higher than 65°C.

(5) The surface of plastic and electronic parts should be bright and clean, without pitting, markings, bubbles, deformation, etc.

(6) When the voltage fluctuation is ±10%, it can also be used normally.

(7) When in use, the noise should generally not exceed 70dB, that is, it should not make people feel disturbed by noise.

(8) The gap between the upper blade and the casing should not exceed 0.75mm, the upper and lower blades should be neat, and there should be no inclination.

(9) The back groove of the lower blade is vertical and clear, the tooth groove is centered, there are no gaps and obvious defects, and the tooth tip should be lubricated.

(10) The surface of metal parts (except the upper and lower blades) should have an anti-corrosion protective layer, and the coating should have a fine luster, and there should be no defects such as spots, pits, pinholes, air bubbles, shelling, and bottom exposure.
