How an Electrical Shaver Works
Electric shavers have a slightly easy construction that attending minor stuff like making a little solder or changing batteries is pretty simple even at home. If you open the back cover, you'll see three main things inside. They're
A collection of chargeable battery
A miniature electric motor
A gear train system
And there are two heavy things on the outside ; they are the switch and the set of blades.
Batteries supply power to a circuitry printed on a fiber glass board called as printed circuit board ( PCB ) when you turn on the shaver. PCB helps organize circuits without screwing up with the moving parts like motor and gears. PCB is an intelligent circuit which decides whether batteries need recharging and if the battery is recharging.
When you start, the motor powers the system of gears which are in turn connected to the blades in a selected sequence that means three gears drive the three blades.
The rotary blades rotate closely inside their various safety cages at speeds variable in two or three steps depending on the model you select. Since the blades rotate, this sort of electric shavers is known as rotary shavers. Some manufacturers suggest using their shavers on wet face, but this doesn't imply you will need to use that foam or lather again. Just soaking the face is enough to moisten the beard. Most other models are dry type.
Who Makes Electric Shavers and how to Buy Them
Even a visit to your near super stores can quickly answer your question. There are numerous reputed models and then there are local and Chinese models available. The top selling brands are simply Philips, Braun, and Panasonic.
Try the features prior to purchasing. If you're looking for just a trimmer, you don't need to get a shaver which hardly helps. Check for battery life-span & standby time and warrantee. Chargeable battery types will be convenient. Men's shavers generally have three heads ( blades ) in contrast to the womens shavers which are slightly different in construction. Check for CEI certification. Buy always from reputed shops. Check whether it comes bundled with cleaning accessories etc .
