In principle, there are two types of electric toothbrushes: rotation and vibration.
1. The principle of the rotary toothbrush is simple, that is, the motor drives the circular brush head to rotate, which enhances the friction effect while performing ordinary brushing actions. The rotary toothbrush is powerful, cleans the tooth surface very clean, and cleans the interdental space relatively weakly, but It is not recommended for long-term use because it is very abrasive to the teeth.
Rotating electric toothbrushes are divided into 360-degree rotation and 90-degree rotation, and 30-degree two-time cycle rotation, which is suitable for children. The tooth of people are uneven. The touch surface of the rotating brush head must fit the tooth specifications to effectively remove the tooth dirt. Otherwise there will be many blind spots.
Vibrating toothbrushes are more complicated, and they are higher-end in terms of price. Vibrating toothbrushes have the vibration motor of an electrically driven can make the brush head produce high-frequency swing perpendicular to the direction of the brush handle, but the swing range is very small, generally about 5 mm up and down, and the industry’s largest swing range is 6 mm.
When brushing teeth, on the one hand, the high-frequency swinging brush head can efficiently complete the action of brushing teeth, on the other hand, it can exceed 30,000 times.
The vibration of every minute also makes the mixture of toothpaste and water in the mouth generate a large number of tiny bubbles, and the pressure generated when the bubbles burst can penetrate deep into the teeth to clean the dirt.
