AI Technical Summary

Technical Problem

Traditional water flossers have single nozzles that create cleaning blind spots, especially when the dental arch is wide, making it difficult to cover the gaps between the upper and lower teeth at the same time. This makes them cumbersome and inefficient to use.

Method used

Design a water flosser nozzle that can simultaneously rinse the gaps between the upper and lower teeth. It adopts a hollow, interconnected spray bar and nozzle. The nozzle has two spray holes with intervals. The water outlet direction is towards the gap area between the upper and lower teeth. The diameter of the spray holes gradually decreases and the spray lines are roughly parallel. The spray bar and nozzle are connected separately. The nozzle structure is designed in a 'Y' shape. The central axis of the spray holes is located on the same plane. The convex spray teeth and the arc-shaped concave surface of the nozzle form a gradient structure.

Benefits of technology

It achieves simultaneous cleaning of the upper and lower teeth with dual water jets, improving cleaning coverage and reducing operation time. The detachable connection design of the spray bar and nozzle improves maintainability and sealing performance, while the protruding spray teeth design reduces gum impact and improves comfort.
