There are three movement modes of the electric toothbrush brush head: one is a reciprocating linear motion of the brush head, the other is a rotary motion, and a complete set of electric toothbrushes with two types of brush heads. The bristles of the toothbrush head are made of soft plastic fibers, and the ends are processed into a spherical shape, which will not damage the teeth and gums, and will not affect the brushing effect. Not only can each tooth be cleaned, but also it can massage the gums. The toothbrush handle has a strong and weak switching mode switch, and the speed of the toothbrush head can be selected according to individual needs. According to foreign reports, in the past few years, quite a few dentists have begun recommending electric toothbrushes to their patients. An electric toothbrush is a tool for cleaning teeth. It consists of a rechargeable dry battery, a miniature DC motor, a battery box, a toothbrush head, a metal shield, and a sleeve. The dry battery as a DC motor power source is installed in the battery box together with the DC motor. There is a manual switch for controlling the power supply of the DC motor. The shaft of the DC motor protrudes out of the battery box. The toothbrush head and the metal protective plate are set on the DC motor shaft. The electric toothbrush is equipped with a variety of toothbrush heads for various users.

　　In addition to daily brushing, it can also be used to massage the gums. When brushing teeth, it can be used manually and manually, and can brush teeth in both directions.
