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. |
