Mechanical isolation prevents rotational transfer to the irrigating nozzle, resolving production cost and speed trade-offs in single-unit oral devices.
Mechanical pause switch interrupts fluid flow via rack and pinion gear actuation, eliminating electrical hazards near water conduits.
A sliding oral cavity washing device uses a rotary lock to release the body from its tank.
A high-velocity gas jet thins liquid film on teeth, preventing plaque removal efficiency loss from reduced droplet impact velocity.
