    摘要： An elongated nozzle (30) for an oral cleaning device (10), the elongated nozzle including: a proximal end (33) with an inlet orifice (36); a distal end (32) with an outlet orifice (42), where the outlet orifice is in fluid communication with the inlet orifice; and at least one structure (50a, 50b) located between the inlet orifice and the outlet orifice, the at least one structure configured to break a liquid droplet traveling through the nozzle into two or more smaller liquid droplets. The at least one structure can also be configured to recapture residual liquid (46) remaining in the nozzle and organize the recaptured residual liquid into at least one liquid droplet (46a, 46b). The structure may be a hydrophobic region that recaptures and organizes the residual liquid.

    摘要： The appliance includes a jet source of fluid, and a nozzle assembly (10) through which the fluid is directed and then out for application to the teeth. A flow interrupter assembly is mounted within the nozzle assembly, such that the interrupter assembly (20) is responsive to the fluid flow to produce momentary successive interruptions of the fluid flow by the action of the interrupter assembly moving from an original position to a flow interrupting position and then returning to its original position as the flow decreases and then is interrupted, due to the fluid flow itself, resulting in a cyclical perturbation in the fluid flow from the nozzle, by flow action alone.
