Electric toothbrushes are becoming more and more popular in our lives. According to our survey, the people who use electric toothbrushes the most are young, but in recent years, with the continuous improvement of electric toothbrushes, the age Range of using electric toothbrushes has been expanding from children to the elderly. Electric toothbrushes have indeed improved our toothbrushing efficiency, and at the same time, the effect of cleaning teeth is better than ordinary toothbrushes. Nowadays, there are many kinds of electric toothbrushes on the market, and the number is increasing, which also makes it difficult for consumers to choose high-quality electric toothbrushes. Before consumers choose electric toothbrushes, they can have a general understanding of electric toothbrushes. For electric toothbrush manufacturers, this article can help you choose a good motor to boost the quality of electric toothbrushes.

The main components of the toothbrush

Let’s first understand the internal structure of an electric toothbrush. An electric toothbrush is a tool for cleaning teeth. It consists of a dry battery, a micro DC motor, a battery box, a toothbrush head, a metal shield, and a sleeve; the dry battery used as the power source of the DC motor is inStalled in the battery box together with the DC motor. The battery box has A manual switch that controls the on and off of the DC motor power supply; the DC motor shaft extends out of the battery box, the toothbrush head and the metal shield are sleeved on the DC motor shaft, and there is a sleeve outside the toothbrush head and the metal shield.

The Working Principle of Smart Electric Toothbrush

Two types of electric toothbrushes go viral nowadays, namely sonic electric toothbrushes and rotary electric toothbrushes. Next, I will briefly introduce their working principles.

1.  Sonic electric toothbrush: In the working process, it mainly relies on the operation of the micro-motor in the toothbrush to drive the toothbrush head to swing at a high Speed from left to right. The toothbrush head generates mechanical vibration, which is sound waves, during the movement. The sound waves generated by the sonic electric toothbrush during operation have different cleaning effects on teeth due to their different frequencies. In general, the cleaning effect of a sonic toothbrush is proportional to its sonic frequency and amplitude.
2. Rotary electric toothbrush: Rotary electric toothbrush mainly uses the operation of the motor inside the toothbrush to drive the round brush head to rotate. It can perform ordinary toothbrush actions while enhancing the friction effect of the toothbrush on the teeth. Compared with the sonic electric toothbrush, the rotating toothbrush The price is relatively low, and its working principle is relatively simple.

Three unavoidable keywords for electric toothbrush selection: frequency, amplitude, and Torque 

Frequency is easy to understand. The faster the toothbrush head swings, the more times the toothbrush head will clean the teeth at the same time, and the cleaning efficiency will be greatly improved. The Current mainstream electric toothbrush vibrations per minute Range from 15,000 to 31,000.

Amplitude: the vibration frequency is just some of the key points for an electric toothbrush to efficiently clean teeth, and amplitude is another vital point. The amplitude of vibration of the head of different brands of electric toothbrushes is usually between 3mm and 5mm. The height of the crown of a normal adult (that is, the part of the tooth exposed outside the gums) is between 7mm and 11mm, and the total height of the crown of the upper and lower jaw will not exceed 20mm. Based on this data, the brush head of an electric toothbrush is generally about 10mm in width, plus a vibration amplitude of about 5mm. The vibration amplitude of the bristles that vibrate during work will not exceed the length of the teeth so that the teeth can be brushed without hurting the gums.

Torque: the amplitude and Torque mentioned above are closely related. Brushing your teeth requires hard wrists. Needless to say, this is also true for electric toothbrushes. When we brush our teeth with an electric toothbrush, we have to press the brush head to the teeth with force, and this force will affect the amplitude of the electric toothbrush, making many electric toothbrushes useless work on your teeth.

Readers who have read the above content should already know that frequency, amplitude, and Torque determine the basic qualities of an electric toothbrush, and these three aspects are indispensable. And what determines the performance of these three aspects is only the core of the electric toothbrush-the motor.

The operation of a smart electric toothbrush is closely related to the built-in DC motor(FK-180SHV-2760G). Therefore, the DC motor is the core component of the electric toothbrush.
