Abstract:
Nozzle device for massaging and/or cleaning purposes comprising:a nozzle body, a central jet channel, which has a first fluid admitted to the central jet channel, an opening region, which widens conically in the jet direction (S) and from which the jet channel extends, and at least two further channels, which open out into the jet channel and via which a second fluid can be fed to the first fluid, wherein the at least two channels open out into the jet channel in a transition region between the jet channel and the conical opening region, wherein respective opening regions of the at least two channels open out into the jet channel in a manner in which they are offset circumferentially through 360Â°/n (degrees), wherein n is equal to the number of further channels and is greater than or equal to 2, wherein in each case one constricting unit is arranged directly upstream, as seen in the jet direction (S), of the opening region in which the at least two channels open out into the jet channel, each of the at least two channels being designed such that each channel can be opened and closed via a corresponding actuating element, and there is provided a control device which activates the actuating element such that each actuating element will open and close alternatively or one after the other in circular sequence or in accordance with a predetermined rhythm.
