Appl. No.:

11/529094

Inventors:

Ronald E. Welch - San Marcos CA, US

International Classification:

E03C 1/04

US Classification:

4675, 4691

Abstract:

A conduit for communication of a pressurized water or fluid supply to a counter top appliance above a sink having a faucet providing water to the sink. The device features an elongated rod having an axial passageway for communication of a fluid when engaged through the drain rod aperture of a faucet. The rod has an exterior circumference sized to translate in the aperture and operate the drain closure apparatus on the sink. A pulsating dental cleaning appliance or water dispenser or knob are engageable to the top end of the rod which is adapted on a bottom end under the sink to engage with a pressurized fluid supply. The device may be provided for retrofit through existing faucets by replacing the drain rod, or with new faucets to provide a route for pressurized fluid above a counter top without having to drill holes in the counter top.

Abstract:

Some embodiments of the present disclosure include a water flosser handle for providing treatment deep into a user's gum pockets. The water flosser handle may include a chamber configured to hold a treatment tablet, a flosser tip attached to a distal end of the handle, and a water supply tube attached to a proximal end of the handle. The handle may be configured to allow passage of pressurized water therethrough into a user's mouth. A treatment tablet may be positioned within the chamber such that the water pressure of the water configured to flow through the handle at least partially dissolves and transports the treatment tablet into the user's mouth and gums.
