摘要:
1. A power-driven toothbrush comprising: a handle (12); a brush head (18) including a set of bristles (24); a drive unit (14) for the brush head; a conductive electrode (25) located in the brush head or on the brush head; a system (28) for measuring the capacitance between the conductive electrode and the ground (27) of the toothbrush in the handle; and also the controller (26), designed to determine whether the measured capacity exceeds a predetermined threshold value indicating that the toothbrush is near the oral cavity or inside the user's oral cavity, and then to activate the drive unit to bring the toothbrush into operation. 2. The toothbrush according to claim 1, wherein the conductive electrode is a shaft integrated in the brush head adjacent to the set of bristles. Toothbrush according to claim 1, characterized in the absence of a mechanical switch on / off. The toothbrush according to claim 1, including an on / off switch (32) configured to control a user, where the drive unit is activated when the on / off switch is in the on position and the measured capacitance exceeds a predetermined threshold value. 5. The toothbrush according to claim 1, wherein the toothbrush operates at a frequency equal to or close to the resonant frequency of the toothbrush. A toothbrush according to claim 1, in which the brush head is removable from the handle, and where the brush head includes an additional capacitive element (38) that allows you to determine the allowed brush heads. The toothbrush according to claim 6, in which the additional capacitive element is a metal ring located in the vicinity of the proximal end of the heads1. Зубная щетка с силовым приводом, содержащая:ручку (12);головку (18) щетки, включающую в себя набор щетинок (24);узел (14) привода для головки щетки;проводящий электрод (25), расположенный в головке щетки или на головке щетки;систему (28) для измерения емкости между проводящим электродом и заземлением (27) зубной щетки в ручке; а такжеконтроллер (
