Abstract
A rigid wand receives water under pressure from a pump. A canister of larger diameter than the wand receives the water from the wand with impact on flow disruptive material promoting aeration by turbulence. A large number of peripheral outlet ports allow water to tumble out of the canister through the ports.
Claims5
A watering wand system comprising:
- a water reservoir;
- a pump connected to said water reservoir;
- a hose having a first diameter joined to said pump to receive water in a sheath flow;
- a rigid wand having a second diameter greater than the first diameter creating a first water pressure reduction and having a first end attached to said hose, and having a second end opposite to the first end;
- a cylindrical outlet canister attached to the second end of the wand, the cylindrical outlet canister having a diameter at least two times the second diameter of the wand, creating a second water pressure reduction, the canister outlet canister having outlet ports in a peripheral wall allowing free flow of water from the canister without an increase in water pressure;
- wherein said water outlet ports are a pattern of canister perforations in the cylindrical outlet canister peripheral wall that account for greater than 50% of a lateral area of said canister wall;
- and
- wherein the cylindrical outlet canister is filled with spherical balls of fibers of the type used for filtering water arranged in a flow disruptive relationship.

A watering wand system comprising:
- a water reservoir;
- a pump connected to said water reservoir;
- a hose having a first diameter joined to said pump to receive water in a sheath flow;
- a rigid wand having a second diameter greater than the first diameter creating a first water pressure reduction and having a first end attached to said hose, and having a second end opposite to the first end, wherein the second diameter allows the sheath flow to collapse;
- a cylindrical outlet canister attached to the second end of the wand, the cylindrical outlet canister having a diameter at least two times the wand diameter wherein the collapse of the sheath flow is complete, creating a second water pressure reduction, the canister having outlet ports in a peripheral wall allowing free flow of water from the canister without an increase in pressure;
- flow disruptive spherical balls of fibers of the type used for filtering water located in the cylindrical outlet canister, for inducing turbulence in the water;
- and
- wherein said water outlet ports are a pattern of cylindrical outlet canister perforations in the canister peripheral wall that account for greater than 50% of a lateral area of said canister wall.

A watering wand system comprising:
- a water reservoir having an outlet port with water under pressure;
- a first conduit connected to the reservoir outlet port, the first conduit having a first diameter wherein a sheath flow from the reservoir is established;
- a second conduit connected to the first conduit having a second diameter, greater than the first diameter wherein the sheath flow begins to collapse creating a first water pressure reduction;
- and
- an outlet canister attached to the second conduit having a third diameter greater than the second diameter wherein the collapse of the sheath flow is complete, creating a second water pressure reduction, the canister having outlet ports in a peripheral wall allowing free flow of water from the canister without an increase in pressure;
- wherein the outlet ports are a pattern of cylindrical outlet canister perforations in the canister peripheral wall that account for greater than 50% of a lateral area of said canister wall;
- flow disruptive spherical balls of fibers of the type used for filtering water located in the canister, for inducing turbulence in the water.
