Abstract
A spray diffuser for a pool cleaner is coupled to the end of the tail sweep hose which expels pressurized water out of the end of the hose. The diffuser includes a flow shaping nozzle configured to form a diverging pressurized water stream. The shaping nozzle can be attached directly to the end of the hose with a flow obstruction of the shaping nozzle immediately adjacent the flow discharge. A dissipating portion dissipates the pressurized water stream when the spray diffuser is positioned above the surface of the water to prevent water spraying out of the pool.
Claims28
A diffuser for a pool cleaner tail sweep, the diffuser comprising:
- a flow shaping nozzle having a first end comprising an inlet opening for receiving an inlet stream of pressurized water from the pool cleaner tail sweep, a second end comprising an outlet opening for discharging an outlet stream of pressurized water, a fluid conduit extending from the inlet opening to the outlet opening, and an obstruction in the path of the outlet stream of pressurized water, the obstruction configured to shape the outlet stream of pressurized water into an at least partially diverging flow pattern;
- and
- a dissipating portion comprising a chamber into which the flow shaping nozzle discharges the at least partially diverging flow pattern, the chamber defining a central conduit extending through the entirety thereof, the dissipating portion comprising at least one dissipation element, and a fluid discharge opening;
- wherein the diffuser operates in a first mode when submerged in a pool of water beneath a water surface, whereby the at least partially diverging flow pattern is directed through the fluid discharge opening of the dissipating portion in a concentrated stream in the first mode of operation when submerged in a pool of water beneath a water surface;
- and
- wherein the diffuser operates in a second mode when positioned above the water surface, whereby the at least partially diverging flow pattern is directed to the at least one dissipation element of the dissipating portion to form a diffuse stream in the second mode of operation when positioned above the water surface.

A diffuser for a pool cleaner having a tail sweep hose, the diffuser comprising:
- a flow shaping nozzle configured for attachment to an end of the tail sweep hose, the flow shaping nozzle having a first end comprising an inlet opening for receiving an inlet stream of pressurized water from the tail sweep hose, a second end comprising an outlet opening for discharging an outlet stream of pressurized water, a fluid conduit extending from the inlet opening to the outlet opening, and an obstruction in the path of the outlet stream of pressurized water, the obstruction configured to shape the outlet stream of pressurized water into an at least partially diverging flow pattern, and wherein the obstruction is positioned immediately adjacent the end of the tail sweep hose when the flow shaping nozzle is attached to the end of the tail sweep hose;
- and
- a dissipating portion comprising a chamber into which the flow shaping nozzle discharges the at least partially diverging flow pattern, at least a central portion of the chamber being free from obstruction, the dissipating portion comprising at least one dissipation element, and a fluid discharge opening.

- and
- a dissipating portion comprising a chamber into which the flow shaping nozzle discharges the at least partially diverging flow pattern, the chamber of the dissipating portion comprising a conduit defined at a central area thereof and extending along the entirety thereof, wherein the dissipating portion operates with a spinning motion relative to the flow shaping nozzle, the spinning motion being rotational about an axis generally aligned with the outlet stream of pressurized water from the flow shaping nozzle.
