Abstract
A floor aspirator is provided. This aspirator features a suction head, having a perimeter, a top surface, a bottom surface, at least one drain between the top surface and the bottom surface, where the at least one drain spans the top surface and the bottom surface, a suction port, which is made up of a suction hole, and a fluid conduit, and a filter, disposed on the suction hole. There exist embodiments where multiple suction ports are featured, as well as embodiments where the top surface is graded towards the at least one drain.
Core Innovation
The invention relates to a fluid aspirator with a substantially planar suction head for aspirating fluid. The suction head has a top surface and a bottom surface, and at least one drain spans between the top surface and the bottom surface. A suction port is recessed from the bottom surface and includes a suction hole, a fluid conduit, and a filter disposed on the suction hole.
In embodiments corresponding to the described configurations, the suction head includes a perimeter and four corners, with angles defined at the corners. The top surface can be graded towards the drain or drains so that the suction head directs spilled fluids into the drains for suction. The suction port and suction hole are recessed, and the suction port can be oriented substantially perpendicular to the suction head.
Another described configuration includes a quadrilateral component having ribbing that divides the top surface into sections. At least one drain is disposed in each section between the top surface and the bottom surface, and the top surface is graded towards the at least one drain. The suction port includes a suction hole and a fluid conduit, and a filter is disposed on the suction hole, with the ribbing dividing the top surface into sections and the drains being disposed per section.
Claims Coverage
The document provides two independent claims. Across these independent claims, the coverage centers on a substantially planar suction head with top and bottom surfaces and drain(s) spanning between them, together with a recessed suction port that includes a suction hole, a fluid conduit, and a filter disposed on the suction hole, with a graded top surface and, in one claim, ribbing that divides the top surface into sections with drains disposed in each section.
Substantially planar suction head with spanning drain(s)
A fluid aspirator comprising a substantially planar suction head having a top surface and a bottom surface, and at least one drain between the top surface and the bottom surface, wherein the at least one drain spans between the top surface and the bottom surface.
Recessed suction port with suction hole, fluid conduit, and filter
A suction port being recessed from the bottom surface, the suction port having a suction hole being recessed from the bottom surface, a fluid conduit; and a filter, disposed on the suction hole.
Quadrilateral component with ribbing dividing top surface into sections
A quadrilateral component comprising a perimeter, a top surface having ribbing, with the ribbing dividing the top surface into sections, and a bottom surface.
Section-wise drains with graded top surface
At least one drain disposed in each of the sections, the at least one drain being between the top surface and the bottom surface, wherein the top surface is graded towards the at least one drain.
Overall, the independent claims collectively require a substantially planar suction head with drain(s) spanning between top and bottom surfaces, a recessed suction port with a suction hole, fluid conduit, and filter, and a graded top surface towards the drain(s), with ribbing dividing the top surface into sections in the quadrilateral configuration.
Stated Advantages
Noise reduction rationale is provided in the description via recessed suction hole and filtered side entry.
Documented Applications
Operating rooms, as described for the disposable floor fluid aspirator.
