Abstract RU 2718317 C2

FIELD: hygiene.

SUBSTANCE: group of inventions includes a packed structure, an electric toothbrush, a handle for an electric toothbrush and a method of fixing the nozzle structure to the handle of an electric toothbrush, relates to the field of medical equipment and is intended for teeth cleaning. Nozzle structure for an electric toothbrush comprises a body having a proximal end and a distal end, the proximal end having a connecting receiving element for connection to the handle shaft of the personal hygiene device. Connecting receiving element has one or more sections of material of thickener on its inner surface, and nozzle structure contains working part of brush. Electric toothbrush comprises a handle including a drive mechanism and a drive shaft, as well as an electric motor controller for controlling operation of the drive mechanism to obtain a mechanical action; and a packed structure. Handle for electric toothbrush includes drive mechanism and drive shaft; electric motor controller to control operation of drive mechanism to obtain mechanical action. Handle contains one or more sections of the material of the thickener on the above drive shaft. Method of fixing the packing structure to the handle of the electric toothbrush includes the following: providing one or more sections of the thickener material on one of the inner surfaces of the connecting receiving member of the seat structure and the drive shaft of the handle; arrangement of the packed structure on the drive shaft of the handle so that the drive shaft and the inner surface of the connecting receiving element are in contact with the thickener material; and control, by means of electric motor controller, operation of drive mechanism on personal hygiene device to obtain mechanical action of drive shaft to thereby increase rigidity or viscosity of said material of thickener.

EFFECT: inventions allow easy removal and replacement of the toothbrush working part, at the same time preventing disconnection of the toothbrush working part during use.
