Abstract
A nozzle (12) for an oral irrigator device (10) having a guidance tip (34) with an orifice at one end, and a dynamic nozzle actuator (64) positioned within said guidance tip. The orifice (36) is configured to expel a fluid as one of a jet, a spray, or any combination thereof. The dynamic nozzle actuator (64) comprises at least one responsive material adapted for being energized and configured to implement at least one dynamic actuation of an effective channel (62) for dynamically influencing at least one of (i) a direction of fluid expelled from the orifice (36), (ii) an angle of fluid expelled from the orifice (36), (iii) a cross-sectional width of fluid expelled from the orifice (36), and (iv) any combination thereof.
