ABSTRACT:
The oral hygiene device comprises a nozzle-holder connectable to a liquid source and a nozzle (1) removably attached to the nozzle-holder, the nozzle being intended for spraying either a multi-jet of liquid via a first duct or a single jet of liquid via a second duct. A two-way valve (5) makes it possible to direct the liquid towards one duct or the other and therefore the branching of the two liquid ducts are located in the nozzle itself. There is a restoring spring (27) which is such that the stable position of the device is for multi-jet spraying, while under the action of an external force exerted on the control member (6) of the valve the device assumes the single-jet position.
