Abstract
A liquid-submersible vacuum system includes a housing enclosing a filtration element and a water pump, and a power converter configured to couple to a standard AC power supply. The vacuum system further includes a vacuum-to-waste assembly detachably coupled to the housing for selectively conveying filtered fluid from the vacuum system to a remote location.
Claims20
A vacuum-to-waste assembly configured to receive filtered fluid from a liquid-submersible vacuum system and convey the filtered fluid to an external location, the vacuum-to-waste assembly comprising:
- a discharge hose cap defining a longitudinal passageway therethrough and configured to couple to a hose, the discharge hose cap including:
- a conical distal end portion including:
- an inner surface;
- an annular ring radially projecting from the inner surface;
- and
- a plurality of tabs extending from the annular ring;
- and
- a cylindrical proximal end portion extending from the conical distal end portion;
- a stator assembly configured to be received in the discharge hose cap, the stator assembly including:
- a conical main body comprising a plurality of discrete components, each having a flange that protrudes radially inwards toward a central area of the conical main body, each flange defining a hole therethrough, wherein adjacent discrete components are secured to each other via the holes of the respective flanges of the adjacent discrete components;
- and
- a plurality of fins protruding radially outward from the main body and extending along a length of the main body, wherein a pair of adjacent fins of the plurality of fins defines a channel therebetween configured to guide fluid proximally through the discharge hose cap, and wherein each component of the plurality of discrete components of the main body includes at least one fin of the plurality of fins,
- wherein each of the plurality of discrete components includes a ¼ section of the conical main body.

A liquid-submersible vacuum system, comprising:
- a housing defining a chamber therein and having a proximal end portion and a distal end portion;
- a DC pump disposed within the chamber and configured to move water proximally toward the proximal end portion of the housing;
- an impeller positioned at the proximal end portion of the housing and configured to rotate in response to an activation of the DC pump, wherein the impeller includes a cylindrical distal end portion and a conical proximal end portion, and wherein the impeller includes a plurality of fins extending radially outward from the conical proximal end portion;
- a filter disposed within the housing, such that water moves through the filter during activation of the DC pump;
- a power converter configured to electrically connect to the DC pump for providing power to the DC pump, wherein the power converter is located remotely from the housing;
- and
- a vacuum-to-waste assembly including:
- a discharge hose cap defining a longitudinal passageway therethrough and configured to be in fluid communication with the chamber of the housing, the discharge hose cap including:
- a conical distal end portion including:
- an inner surface;
- an annular ring radially projecting from the inner surface;
- and
- a plurality of tabs extending from the annular ring;
- and
- a cylindrical proximal end portion extending from the conical distal end portion;
- and
- a stator assembly configured to be received in the discharge hose cap, the stator assembly including:
- a main body configured to be positioned adjacent and proximally of the impeller, wherein the main body of the stator assembly is comprised of a plurality of discrete components;
- and
- a plurality of fins protruding radially outward from the main body and extending along a length of the main body, wherein a pair of adjacent fins of the plurality of fins defines a channel therebetween configured to guide fluid proximally through the discharge hose cap, wherein each component of the plurality of discrete components of the main body includes at least one fin of the plurality of fins, wherein a number of the plurality of fins of the impeller is equal to a number of the plurality of fins of the stator assembly, and wherein each of the plurality of fins of the impeller extends at an angle relative to a respective fin of the plurality of fins of the stator assembly,
- wherein each of the plurality of discrete components includes a ¼ section of the main body.
