I know there are many cheaper electric toothbrushes, especially those sold by wechat business. I have used them and if the bristles are of good quality, I can accept it. If they are cheap, you can buy them and try them.Finally, when I get a good electric toothbrush, the first thing I do is to learn how to brush my teeth carefully. I know what the Bass brushing method is and what the rolling brushing method is. As an orthodontist, I've been reading this stuff on internet countless times.Correct use of electric toothbrush is the basic guarantee of clean teeth.

Electric toothbrushes are becoming more and more popular these years. We have all used electric toothbrushes in our dormitory.How to choose so many electric toothbrushes after all?Taking advantage of the lack of class, combined with our dormitory sisters have stepped on the pit, talk about the purchase of electric toothbrush, how to avoid pit.At present, the mainstream electric toothbrush on the market can be divided into three categories, which are rotary electric toothbrush, acoustic electric toothbrush and hybrid electric toothbrush.Rotating toothbrush principle is simple, is the motor drive circular brush head rotation, in the implementation of ordinary brushing action at the same time to strengthen the friction effect, rotating toothbrush strength, tooth surface cleaning is very clean, cleaning between teeth is relatively weak, but the tooth wear is large, it is not recommended to use for a long time.It is mainly represented by a big-brand electric toothbrush.

Electric toothbrush is such a existence, regardless of the rotating friction electric toothbrush or ultrasonic vibrating electric toothbrush, always improve the efficiency of the cleaning, cooperate now smart vibration mode, timing reminder, even some brand electric toothbrush can also record a toothbrush to clean the Angle and position of the whether to prompt the brush teeth thoroughly, it's all in the experience of ascension to brush your teeth and efficiency.

First, cost: the most expensive part of an electric toothbrush is the motor, which is divided into two kinds: the brush motor, the brush motor with a coil, the rotor to wind the electromagnetic coil, the frequency and torque constraints are great, it is difficult to achieve the same excellent frequency and torque.Many electric toothbrushes on the market use a reciprocating motor with a brush. Due to the friction of the brush, there will be additional noise when working.Brushless motor, because there is no carbon brush, so low friction, low loss.Brushless motor is usually digital frequency conversion control, strong controllability, from a few revolutions per minute to tens of thousands of revolutions per minute can be easily realized.This brushless motor is used in the control requirements are relatively high, high speed equipment.Usually, high-end electric toothbrushes have strict control over the motor speed.

The electric toothbrush of ten yuan, I always think that the brush head can be made a little bigger, so I can brush the shoes.More than ten dollars of shoe brush artifact, is simply the conscience of domestic goods!Anyway, their data is wrong, and the frequency amplitude is not one of the number.
