FIELD: medicine. ^ SUBSTANCE: group of inventions relates to field of hygiene and can be used in electric toothbrushes, which have engine and drive shaft. Cleaning section contains: bristle holder, head, including first set of immovable bristles, located in immovable part of bristles, and second set of movable bristles, fixed inside bristle holder. First set of immovable bristles and second set of movable bristles are located in alternating rows transverse to first head axis. First head axis coincides with longitudinal axis of cleaning section. Bristle holder is made with possibility of travel and obtaining drive motion from engine by means of drive mechanism. Drive mechanism contains drive shaft, made with possibility to perform fluctuations around its longitudinal axis. Bristle holder is made with possibility to travel in such a way that second set of movable bristles has, at least, one degree of free movement with respect to first set of immovable bristles. Bristle holder is made with possibility to travel relative to head and immovable part of bristles in such a way that cleaning movement of the second set of movable bristles includes fluctuating movement with respect to first set of immovable bristles, induced by fluctuating movement of drive shaft. Group of inventions includes second version of cleaning section. ^ EFFECT: extending possibilities of range of brush section movements. ^ 18 cl, 12 dwg |
