What should I pay attention to when purchasing electric hair clipper?

First, the cutter head design

Hair clipper's cutter head materials are generally stainless steel, carbon steel, iron sheet, ceramics, titanium alloy and so on. At present, there are two common materials on the market, stainless steel cutter head and ceramic cutter head.

The cutter head of hair clipper consists of two rows of teeth with blades that overlap up and down. Generally, the teeth in the upper row are called moving knives and the teeth in the lower row are called fixed knives. During use, the fixed knife is stationary, and the moving knife is driven by the rotation speed of the motor to move back and forth quickly to cut the hair. Therefore, the cutter head is a combination of two materials: our fixed cutter is basically made of metal, and the moving cutter can be made of different materials, so generally speaking, the material of the cutter head refers to the moving cutter material. The hardness of steel knives is Vickers HV700, and that of ceramic knives is HV1100. The higher the hardness, the sharper the knife, and the higher the value, which is convenient to use.

Stainless steel cutter head: more wear-resistant and fall-resistant. However, after use, you should pay attention to maintenance. To dry the water, it is best to rub some oil, otherwise it will rust easily.

Ceramic cutter head: strong shearing force, not easy to rust, almost no heat generated when working, little wear and durability. There is little noise at work, but you can't fall because it is ceramic.

Titanium alloy: titanium alloy itself contains little titanium, because if there is too much titanium, the cutter head will not be sharp. Although heat-resistant and durable, the price is relatively high.

Second, the noise index

For small household appliances, the less noise, the better. Therefore, attention should be paid to noise decibels when choosing products, especially for younger babies. You need to buy a mute hair clipper, and the decibel value should be controlled at 40-60 decibels.

Three, caliper type

Calipers, also known as limit combs, are accessories to help trim short hair. Specifications are generally 3mm, 6mm, 9mm and 12mm. There are two adjustment methods. One is manual disassembly and replacement, which is a little troublesome to use. You need to manually disassemble one and replace it with another every time. The other is one-button adjustment. The limit comb and hair clipper are designed together, which can be adjusted at will by sliding or rotating on the hair clipper, and the adjustment length can be from 1mm to 12 mm. For thick and hard hair, it is recommended to use 3-6mm, and for thin and soft hair, it is suitable for 9-12 mm. Of course, you can choose a suitable limit comb according to your hair style needs.

Fourth, power and power supply

Hair clipper's power is the speed of the motor. At present, there are mainly: 4000 rpm, 5000 rpm and 6000 rpm on the market. The larger the number, the faster the rotation speed and the stronger the power. The stronger the motivation, the smoother the haircut process will be, and there will be no jam. You can choose the power according to the hair quality. 4000 rpm is suitable for children and adults with soft hair, 5000 rpm is suitable for ordinary people, and 6000 rpm is suitable for adults with hard hair.
