The nozzle includes a tooth processing unit 1 including a removable operating element (RE) 5 and a drive shaft (PV) 4, one end of which is provided with a means of kinematic interaction with the PE5 with the possibility of rotation transfer. The second end of the PV4 is mechanically coupled to the means 43 for effecting kinematic interaction with the shaft of the toothbrush motor. Block 1 also includes a visor 6 with a longitudinal protrusion 7 disposed opposite to the RE5 with the possibility of touching the surface of the PE5. The nozzle is equipped with a removable hollow body (PC) 2 with a seating surface 14 formed on it, the shape of which corresponds to the portion of the reciprocal surface of the toothbrush body. The drive shaft 4 with the kinematic interaction means at its ends is entirely housed in the PC 2 and is made of two telescopically coupled (with the possibility of torque transmission) of the driving and driven parts 12 and 13. The unit 1 is provided with a means 8 for the return- translational movement of the follower part 12 relative to the driving part 13 while the rotation of the PV4 and the means 3 for reducing the speed of rotation of the driven part 13 of the PV4, and also the automatic reversing mechanism PV4. Removable RE5 protrudes beyond PC2, and visor 6 is located on PC2. On the outer surface of the peak 6, two electrically conductive paths 9 are provided with output contacts 41 on the surface 14 of the PC2. Lanes 9 are designed to interact with the contacts of an open single-pole branch of the electric circuit of the toothbrush. Lanes 9 with contacts 41 are a means of automatically closing / opening the electric circuit of the toothbrush through the oral mucosa of the user. 14 z.p. f-ly, 14 ill.Насадка включает блок 1 обработки зубов, включающий съемный рабочий элемент (РЭ) 5 и приводной вал (ПВ) 4, один конец которого оснащен средством кинематического взаимодействия с РЭ5 с возможностью передачи вращения.
