Abstract

The present invention describes an apparatus and teaches a method for removing particulate matter from a plurality of vessels. Examples of these vessels include aquariums, spas, fountains and pools. An ordinary hand held power drill motor is connected via a drill motor pump to a pick-up head containing a pair of hoses. Upon activation, a first hose applies suction to the pick-up head drawing both water and particulate into a chamber. The water continues through to a pump mounted in a housing, through the pump and out the discharge hose while the particulate is trapped within the chamber by a filter for later removal.

Claims

1. An apparatus for removing particulate matter contained in a liquid stream from a plurality of vessels, comprising:

a hand held drill motor;

a flexible drive shaft;

a pump housing unit having a handle and containing a drill motor operated pump, said drill motor operated pump connected to said hand held drill motor by said flexible drive shaft such that when said hand held drill motor is activated said drill motor operated pump operates;

a wand assembly, said wand assembly further comprised of;

a wand shaft, wherein one end of said wand shaft is fixably attached to said pump housing unit;

a pick-up head, said pick-up head attached to the opposite end of said wand shaft, said pick-up head further containing an inlet chamber, an outlet chamber, and inlet valve and a filter, and;

a suction hose and a discharge hose routed within said wand shaft, wherein a first end of said suction hose is connected to the inlet side of said drill motor operated pump and a second end of said suction hose is connected to said inlet chamber of said pick-up head, and wherein a first end of said discharge hose is connected to the outlet side of said drill motor operated pump and a second end of said discharge hose is connected to said outlet chamber of said pick-up head.

2. The pump housing unit of claim 1 wherein the housing of said control unit is made of plastic.

3. The pump housing unit of claim 1 wherein the housing of said control unit is made of aluminum.

4. The wand assembly of claim 1 wherein the length of said wand is approximately twelve inches, said wand assembly suitable for cleaning shallow vessels.

5. The wand assembly of claim 1 wherein the length of said wand is approximately thirty-six inches, said wand assembly suitable for cleaning moderately deep vessels.

6. A method for removing particulate matter contained in a liquid stream from a plurality of vessels, comprising:

attaching a hand held drill motor to a pump housing unit by means of a flexible drive shaft, said pump housing unit having a handle and containing a drill motor operated pump, said drill motor operated pump connected to said hand held drill motor by said flexible drive shaft such that when said hand held drill motor is activated said drill motor operated pump operates;

connecting a wand assembly to said pump housing unit, said wand assembly further comprised of;

a wand shaft, wherein one end of said wand shaft is fixably attached to said pump housing unit;

a pick-up head, said pick-up head attached to the opposite end of said wand shaft, said pick-up head further containing an inlet chamber, an outlet chamber, and inlet valve and a filter, and;

a suction hose and a discharge hose routed within said wand shaft, wherein a first end of said suction hose is connected to the inlet side of said drill motor operated pump and a second end of said suction hose is connected to said inlet chamber of said pick-up head, and wherein a first end of said discharge hose is connected to the outlet side of said drill motor operated pump and a second end of said discharge hose is connected to said outlet chamber of said pick-up head;

immersing said pick-up head of said wand assembly into a vessel to be cleaned, placing said pick-up head in close proximity to particulate matter to be removed from said vessel;

activating said drill motor operated pump by depressing said trigger thereby causing said pump to operate creating a stream of liquid, said stream of liquid further causing a pressure differential to exist across said inlet valve of said pick-up head, said pressure differential causing said particulate matter proximate to said pick-up head to be sucked into said pick-up head;

separating said particulate matter from said stream of liquid within said pick-up head by a filter means;

deactivating said trigger causing said pressure differential to be lost further causing said inlet valve to close thereby trapping said particulate matter within said pick-up head;

removing said wand from said vessel;

detaching said pick-up head from said wand, and;

discarding said particulate trapped within said pick-up head.
