How does the tooth washer work?

Tooth washing machine cleans teeth by generating pulsed water flow. In a certain range, the higher the pulse frequency, the better the cleaning effect. High pulse rate is more suitable for cleaning tiny objects with strong adhesion, which is also the technical principle of cleaning dental calculus with ultrasonic dental scaler and ultrasonic cleaning machine in hospitals.

At present, there are two common types of punches:

One is a frequency conversion tooth washer, which uses a high-power DC motor and controls the pulse frequency through a computer chip to realize the frequency conversion control of water flow. The frequency control range is 800- 1600 times/minute. The motor has no heat and can be used continuously. At the same time, the internal circuit adopts DC low-voltage design, and the working voltage is lower than 16V, which belongs to safe voltage below 36V, so as to ensure the electrical safety in the water environment around the washstand in the bathroom. ?

The other is a portable personal tooth washer, which is compact and convenient to carry. It is mainly used by orthodontists after meals, and it is easier to clean teeth.
