TECHNICAL FIELD
[0001] The utility model relates to electric toothbrush technical field especially relates to a kind of micro-current healthy teeth electric toothbrush. BACKGROUND
[0002] There are sonic toothbrushes and micro-current toothbrushes on the market, but there are no sonic electric toothbrushes with high-frequency vibration and toothbrushes with micro-current. Because it is difficult to achieve two functions at the same time in structure, we have made innovations in structure, so that the toothbrush can conduct electricity to the brush head while vibrating at high frequency, and then input 10MHz frequency and micro-current to the brush head from the mainboard through a specific chip, so that the toothbrush can clean while vibrating with sound waves, and when the ultrasonic waves pass through the liquid medium, the liquid medium will vibrate at a very high frequency, causing the liquid molecules to produce positive and negative alternating shock waves. When the sound intensity reaches a certain value, the liquid rapidly grows micro-cavitation bubbles and closes instantaneously, producing strong micro-explosions and shock waves that destroy the dirt on the surface of the cleaned object and cause it to fall off the cleaned surface. Although each cavitation bubble has little effect, but there are hundreds of millions of cavitation bubbles acting every second, which has a good cleaning effect. Because ultrasonic waves can penetrate solid materials and make the entire liquid medium vibrate and produce cavitation bubbles, this cleaning method does not have dead angles that cannot be cleaned, and industry has proven that ultrasonic cleaning has high cleanliness.
