Origin of electric toothbrush
Just as Viagra was originally invented to treat cardiovascular diseases, electric toothbrushes were originally invented to help disabled people brush their teeth. In 1954, the first electric toothbrush in the world, the Broxodent, was invented by Dr. Philippe-Guy Woog Wug from Switzerland. It was launched at the centennial of the American Dental Association by Stelboard Pharmaceuticals in 1959. In the following decades, the electric toothbrush developed rapidly. In 2003, electric toothbrushes beat cars, personal computers, mobile phones and microwave ovens to become the first "indispensable invention" in American life.
Classification of electric toothbrushes
There are mainly two kinds of electric toothbrushes: mechanical rotary electric toothbrush and sonic electric toothbrush.
Rotary electric toothbrush, which is structurally connected with worm wheel by multi-stage gear, can rotate, swing and reciprocating motion of the brush head. Mechanical rotary electric toothbrushes usually brush teeth more forcefully and make more noise.
There is an electrically driven vibration motor inside the sonic electric toothbrush, which can make the brush head oscillate at high frequency perpendicular to the direction of the brush handle, but the oscillation amplitude is very small, generally about 5 mm up and down, and the maximum swing in the industry is 6 mm. When brushing teeth, on the one hand, high frequency swinging brush head can effectively complete the action of brushing teeth. on the other hand, more than 30,000 times per minute vibration water power can go deep into the teeth to remove dirt. sonic electric toothbrush also has better cleaning performance and works in a relatively mild way, which can better protect teeth from damage.
