ABSTRACT:
The invention relates to a jet tip on the handle of an oral hygiene appliance. The jet of the jet tip has an opening in which a slidable core piece is displaceable, which core piece exposes only the output openings for a multiple stream in one of its two extreme positions in the jet and only a single output opening for a single stream in its other extreme position. Advantageously, when the core piece moves from one extreme position to the other, contaminants or calcium deposits are automatically and mechanically removed from the outlet opening or outlet openings which is or are not exposed. The core piece can be positively mounted in the jet and be movable by pressure or tension force exerted by a spring and be thereby automatically locked into its two extreme positions.
