FIELD: hygiene.
SUBSTANCE: group of inventions includes an electric toothbrush and a monolithic charging coil framework for an electric toothbrush is a medical technique and is intended for cleaning the oral cavity. Electric toothbrush contains an elongated body open at the proximal end; a frame located in the body, a rechargeable battery; control circuit in electrical connection with the battery; and a charging coil frame disposed at a proximal end of the housing comprising a bridge spring. Bridge spring has two ends and is located transversely with a distal end of the frame spaced arrangement. Body and frame of the charging coil are rigidly coupled to one another by means of grooves or tongues on the inner surface of the body adjacent to the proximal end and corresponding tabs or grooves disposed on the charging coil frame. Charging coil frame and the bridge spring are additionally arranged in elastic contact with the frame. Bridge spring is sized to absorb the distal end of the elongated body axial impact. Monolithic charging coil frame for an electric toothbrush comprises a carcass body having a central axis; the coil winding surface located at the proximal end of the carcass body; first and second housing connecting tongues; and a bridge spring having first and second ends. Bridge spring is sized to absorb the distal end of the elongated body axial impact.
EFFECT: inventions can increase the durability of an electric toothbrush by absorbing axial impacts.
