Brush Section For An Electric Toothbrush

An electric toothbrush, comprising:

• a handle section, a motor, a gear, and a transmission;
• a brush section structured to be push-fitted onto the handle section including a mounting tube and a brush head portion, at least one movable contact element connected to a movable contact element holder, and at least one static contact element attached to the brush head;
• wherein the transmission converts rotational movement provided by the motor into an oscillating movement at a drive shaft having a longitudinal axis;
• the brush section is removably attachable to the handle section of the toothbrush;
• and the movable contact element holder is mounted in and pivotably movable relative to the brush head and is removably and operatively connected to the drive shaft, such that the oscillating movement of the drive shaft causes the at least one movable contact element to move relative to the at least one static contact element in a back and forth oscillating movement about the longitudinal axis.

An electric toothbrush, comprising:

• a handle section, a motor, a gear, and a transmission;
• a brush section structured to be push-fitted onto the handle section including a mounting tube and a brush head portion, a plurality of movable contact elements connected to a movable contact element holder, and a plurality of static contact elements attached to the brush head;
• wherein the transmission converts rotational movement provided by the motor into an oscillating movement at a drive shaft having a longitudinal axis;
• the brush section is removably attachable to the handle section of the toothbrush;
• and the movable contact element holder is mounted in and pivotably movable relative to the brush head and is removably and operatively connected to the drive shaft, such that the oscillating movement of the drive shaft causes the at least one movable contact element to move relative to the at least one static contact element in a back and forth oscillating movement about the longitudinal axis;
• and at least a portion of the plurality of static contact elements and at least a portion of the plurality of movable contact elements are arranged in rows generally transverse to the longitudinal axis, the rows being alternate rows of the static contact elements and the movable contact elements.
