Abstract
A hand-held appliance for mouth and tooth care with a grip portion having a manipulating element that is designed as a sliding switch and that is capable of being shifted in an axial direction. A push button is guided on inclined surfaces in the interior of the shell of the grip portion and reaches through a slot in the shell as well as through a cutout in the manipulating element. In the interior of the grip portion the push button rests on a pinch tube via a ball. The provision of the inclined surfaces results in the push button increasingly moving into the grip portion and increasingly squeezing off a pinch tube when the manipulating element is pushed forward. Independently thereof, the push button is at any given moment capable of being moved into the grip portion far enough to interrupt the water flow.
