Abstract
A toothbrush includes a shell, a driving mechanism and a turning-and-moving mechanism mounted in the shell, and a brush connected to the turning-and-moving mechanism. The brush includes a main-brush and side-brushes mounted respectively on both sides of the main-brush. With the structure of the brush, the brush is capable of simultaneously brushing the inner side surfaces, the outer side surfaces, and the top surfaces of the teeth. With the turning-and-moving mechanism and the driving mechanism, the brush can move back and forth linearly and adjust the overall direction and the moving direction of the brush depending on orientations of teeth. The brush can accommodate various sizes and shapes of the teeth and the brush can adapt to the arrangement of the teeth in the dental arch.

- a shell having:
- a grip part;
- and
- a brush end extending from an end of the grip part;
- a driving mechanism mounted in the grip part of the shell;
- the driving mechanism having:
- a drive motor;
- a power supply module electrically connected to the drive motor and being capable of providing working power to the drive motor;
- and
- a control module electrically connected to the drive motor and being capable of controlling the drive motor to rotate or not;
- a turning-and-moving mechanism mounted in the brush end of the shell, the turning-and-moving mechanism connected to and controlled by the drive motor;
- and
- a brush defining a cleaning space;
- the brush including:
- a main-brush and two side-brushes surrounding the cleaning space;
- wherein the main-brush includes:
