摘要： A two-stage filtering drain cover that can be retrofitted to an existing, original construction, areaway drain cover. The filtering drain cover of the invention inhibits the accumulation of debris on the existing drain cover, and passage of debris into the drain, and helps to prevent clogs and flooding. The outer cover member of the device is configured with passages that permit liquid flow through the outer cover while filtering larger size debris particles that may be entrained in the passing liquid. A perimeter wall on the outer cover and with similar liquid flow passages stops larger debris from passing the outer cover. An inner filter member fits within the outer cover and is configured with relatively smaller passages to obstruct smaller sized debris that may have penetrated the outer cover from passing into the drain.

摘要： A hair collector assembly includes a flat disk having an outer circular or oval frame supporting an inner mesh material that can be placed over the drain opening to block the opening. The outer circular frame may include a lower ring contacting the upper surface of the sink or tub and preventing movement of the disk. The lower ring may snap into an upper ring which together retain an outer perimeter of a mesh material forming an inner surface of the disk and preventing the passing of hair, grease, and other sticky substances through the mesh material into the drain.

摘要： A garbage separator system (500) is provided, the system configured to separate water from waste, garbage, and food particles as they flow down a sink drain. In some embodiments, the system includes a screw drive (508) configured to be mounted beneath the drain of a sink and to rotate to convey waste particles laterally away from the underside of the drain of the sink (e.g., toward a bin for collecting waste particles (518)) while allowing water to drain through a plurality of drainage holes in a tube encasing the screw drive.

摘要： A drain lock sealing apparatus is positioned in a drain pipe for being locked therein and further for sealing the pipe to prevent odors and vermin from coming from the drainpipe into the room. The apparatus includes a grate positioned over the drain pipe, a resiliently deformable sealing ring extending from the grate into the drainpipe, an rigid expander member with an inwardly tapered outer surface extending into the sealing ring, a resiliently deformable frusta-conical member attached to center hub of the expander member so that the peripheral closure edge of the frusta-conical member is in non-fixed normally closed relationship against the circumferential edge of the expander member so that the closure edge opens in response to liquid passing through the grate into the drain and resumes normally close relationship in response to the secession of liquid passing through the grate. A bolt extends through the grate and cylindrical sealing ring and is screwed into the axial hole whereby tightening of the bold compresses the sealing ring axially to deform the cylindrical sealing ring radially into clamping engagement against the interior surface of the drain pipe.

摘要： A sink strainer basket includes a strainer body and an odor prevention arrangement. The odor prevention arrangement includes a drain regulator and a filtration handle. The drain regulator is provided on the strainer body to fully occupy a drainage opening. The drain regulator includes a main drainer body having a sewage passageway, and a blocking assembly movably mounted on the main drainer body to normally close the sewage passageway. The filtration handle extends from the drain regulator to be supported in a drainage cavity. When liquid and larger items are drained in the sink strainer basket, the larger items are filtered by the filtration handle, while the liquid is allowed to pass through the filtration handle to push the blocking assembly to open for draining of the liquid through the sewage passageway.
