Patent ID: 6934975

Claim:
An accessory drain clearing apparatus adapted for use with a separate spray nozzle at one end of an extendable hose to clean a sink drain, said accessory drain clearing apparatus comprising: a molded adapter member against which the spray nozzle can be pressed when positioned in a drain opening and being engagable with the separate spray nozzle adjacent to the drain opening and disengagable therefrom adjacent to the drain opening and having a central fluid passage fluidly communicable with said nozzle and permitting the passage of water therethrough, the central fluid passage extending through a cylindrical projection extending upwardly from a flat generally circular adapter base, the cylindrical projection being adapted to capture water spray from the spray nozzle and forming a conical surface engagable with the spray nozzle adjacent the drain opening, the conical surface being located adjacent to the adapter base, the base extending beyond the cylindrical projection and beyond the spray nozzle when in engagement with the cylindrical projection, the base including a lower surface for closing the drain opening except through the central fluid passage when the central fluid passage is aligned in communication with the drain opening, the conical surface continuously diverging upwardly from the lower surface of the base to an upper end of the cylindrical projection and wherein an annular rim extends upwardly from the adapter base defining a toroidal gap between a portion of the cylindrical projection containing the conical surface and the annular rim, the accessory drain cleaning apparatus improving the effectiveness of water ejected by the spray nozzle through the central fluid passage in removing impacted matter from the sink drain.
