US 4,863,108 A · Animal excrement dissolver

Abstract

An apparatus for breaking up, dissolving and flushing away animal excrement left on the ground or lawn includes a hollow cylindrical handle section coupleable to a garden hose at its upper end, and terminating in a hollow, frusto-conically shaped spray head at the lower end of the handle section. The spray head includes a hollow exterior shell section, and an orifice plate transversely positioned within the hollow interior space of the shell sections, the orifice plate having plurality of regularly spaced orifices whose entrance openings communicate with pressurized water introduced into the upper end of the shell section by the handle section, and whose lower exit openings produce streams of water at various angles adapted to efficiently break up a pile of animal excrement. Spikes protruding perpendicularly downwards from the lower surface of the plate and extending below the lower annular wall surface of the spray head shell provide a mechanical breaking action when vertically and/or rotationally impacted against a pile of animal excrement, to assist the hydrodynamic ablation action of the water jets.

Dependent claims

An apparatus for dissolving and flushing away animal excrement left on a surface comprising;

a. an elongated hollow tubular handle section provided with an axial bore having an upper opening at one end of said handle section, and a lower opening at the lower end of said handle section,
b. means for introducing fluid under pressure into said upper opening of said handle section,
c. a generally frusto-conically shaped spray head shell having a hollow interior space, said spray head shell being fastened at its upper, smaller diameter end to the lower end of said handle section so as to sealingly couple said lower end of said bore and said handle section with said hollow interior space of said spray head shell, and
d. a relatively thin orifice plate of generally uniform thickness sealingly joined at its outer perimeter surface to the inner wall surface of said spray head shell, said plate being located transversely to the longitudinal axis of said spray head shell, said plate having a plurality of orifices through its thickness dimensions, and said plate having a plurality of spike-like appendages protruding perpendicularly downwards from the lower surface of said plate.
