Abstract
A rinsing device for personal hygiene, particularly a mouth-washing device, operates as a liquid pulse generator. This is provided with a pressure-water passage which can be connected to a source of pressure water and an outlet to which a spray nozzle can be connected, preferably via a flexible tube. A rotary valve is included which can be set in rotation and is mounted between the pressure-water passage and the outlet. The rotating valve is adapted to close the outlet intermittently to produce a pulsating jet of liquid. A turbine is adapted to drive the rotary valve and is provided with at least one tangentially oriented jet opening at its periphery and which is in communication with the pressure-water passage.
