Electric shavers work entirely differently from blade razors as their cutting action is scissor-like, unlike the blade action which is direct skin contact.
The hairs get into the razor screen which is perforated then the moving blades which are inside the electric razor at that point sever them. The blades are connected to a motor which keeps moving them in a circular manner against the foil in between your skin and the shaver.
The blade is less irritating since the blade does not graze the skin of the user but the razor inside.
Electric in electric shaver defines the movement of the blades using electricity. The razors can be fueled by a battery powered or corded source of energy. Modern electric shavers mostly use rechargeable batteries.
These components are electrical and very safe to use with water during cleaning and also they are water resistant. Most of the electric shavers do not require water or cream lubrication. Electric shavers are two types:
1.) Foil shavers.
Foil shavers work in such a way of moving the razor forth and back under the screen or foil. The shaver screen is perforated to allow hair to fall out through the perforations. Foil shavers contain at least four blade rows arranged in a line.
As the blade moves forth and back, it cuts any hair that gets into the foil perforations. Various foil shavers have varied numbers of foils. The many foils lie on each other to cover the blades. Foil shavers are named as per the number of foil layers they have. Foil shaver containing three foil layers are called triple foils.
2.) Rotary shavers.
Rotary has foils round and are held by springs in place. The springs act as the foils pivot to allow confirmation to the person being shaved face curves.
Beneath the foils are wheels fitted with blades on them. The wheels spin round and cut any hair that gets into the perforations of the foil. The cut hair then falls into the razor’s hollow parts leaving the skin free from irritation resulting from direct skin blades.
