Furthermore, the carrier has on it Back a peg that goes into a hole in the bottom of the Housing engages and an exposed at the back of the head Printing area forms. The carrier is in the head snapped into place and can be ejected by pressing on the peg become. The one to be replaced when the bristles wear out Plastic mass is reduced to a minimum and that interchangeable brush parts can be due to the low cost manufacturing.
  • a very stable and permanent connection of the brush part and head results from a known toothbrush (DE 41 04 314 A1) in that on the back of the Bracket molded two V-shaped strips to each other that run the entire length of the beam. These engage in a corresponding V-shape opening slot on the head, in the longitudinal axis also runs over the entire length.
  • the elastically deformed parts of the Resting connections are therefore on the interchangeable part, where material fatigue is less significant.
