An electric toothbrush for teeth cleaning, comprising:
- a main body;
- a head comprising a stem and a rotating element, arranged at one end of said stem, the rotating element including a plurality of bristles and being able to rotate according to a first rotation direction and a second rotation direction opposite to said first rotation direction, said head being connected to said main body in an articulated manner;
- a transmission shaft at least partially located in the stem of the head and provided to rotate the rotating element of the head;
- a motor powered by a power supply means and adapted to generate a rotary motion transmissible through the transmission shaft to the rotating element of the head, so as to generate rotation of said rotating element according to the first rotation direction and the second rotation direction;
- the motor and the power supply means being arranged inside the main body;
- said electric toothbrush further comprising:
- a first push switch provided to detect a relative inclination of the head with respect to the main body in accordance with a first flexion direction, the first push switch being arranged around the transmission shaft so that the first push switch is pressed by the transmission shaft when the transmission shaft is inclined with respect to the main body according to the first flexion direction, where pressing of the first push switch causes rotation of the rotating element of the head according to the first rotation direction via the motor;
- a second push switch provided to detect a relative inclination of the head with respect to the main body in accordance with a second flexion direction, opposite to said first flexion direction;
- the second push switch being arranged around the transmission shaft so that the second push switch is pressed by the transmission shaft when the transmission shaft is inclined with respect to the main body according to the second flexion direction, pressing of the second push switch causing rotation of the rotating element of the head according to the second rotation direction via the motor;
- a third push switch provided to detect a relative inclination of the head with respect to the main body according to a third flexion direction perpendicular to said first flexion direction and said second flexion direction, the third push switch being arranged around the transmission shaft so that the third push switch is pressed by the transmission shaft when the transmission shaft is inclined with respect to the main body according to the third flexion direction, pressing of the third push switch causing rotation of the rotating element of the head according to the first rotation direction or the second rotation direction via the motor;
- a plurality of inclination switches provided to detect rotation of the electric toothbrush from a first predetermined position to a second predetermined position around an axis (z) longitudinal to the electric toothbrush, the second predetermined position being rotated by +90° or −90° with respect to the first predetermined position;
- wherein, when the electric toothbrush is in the first predetermined position, even if the third push switch is pressed, the third push switch not causing rotation of the rotating element via the motor, and pressing of the first push switch or of the second push switch causing rotation of the rotating element via said motor;
- and
- wherein, when the electric toothbrush is in the second predetermined position, even if the first push switch and/or the second push switch is/are pressed, rotation of the rotating element not being caused via the motor, and pressing of the third push switch causing rotation of the rotating element via said motor.
