Patent ID: 8418712

Claim:
An air discharge implement for a portable pressurized sprayer comprising: a main body; an external hood jacket; a conical moving plug; and a compression spring, wherein said main body is a hollow tube that includes a cylinder bore, and a cylindrical discharging mount, said discharging mount including a central internal hollow discharge chamber and an air passage interposed between said hollow discharge chamber and said cylinder bore; wherein said external hood jacket is an inverted hollow bucket-shaped holder secured to said cylindrical discharging mount of said main body and that includes a discharging vent, an airflow passage, and an intake chamber such that said discharging vent and airflow passage as well as said airflow passage and an intake chamber are in respective fluid communication, and a diameter of said intake chamber is bigger than that of said airflow passage while a diameter of said airflow passage is bigger than that of said discharging vent; wherein said conical moving plug is movably situated in said hollow discharge chamber of said main body and includes a top cone and a planar base with one of a plurality of footing legs extending from the base or a plurality of grooves; and wherein said compression spring is positioned in said airflow passage of said external hood jacket such that a bottom of the compression spring contacts said top cone of said conical moving plug, an inner diameter of said compression spring being less than an outer diameter of said top cone such that said compression spring presses said planar base of said conical moving plug against said hollow tube, whereby, when said planar base of said conical moving plug is pressed against said hollow tube, air in said cylindrical bore of the hollow tube passes into said hollow discharge chamber of the cylindrical discharging mount by passing through said air passage and between said plural footing legs or through said plurality of grooves, said air passing from the hollow discharge chamber through the intake chamber, air flow passage, and discharging vent of the external hood jacket, whereby as pressure of water flowing through said cylindrical bore of the hollow discharge chamber increases, said conical moving plug is moved away from the hollow tube to permit additional air to flow through said air passage and into said hollow discharge chamber and from the hollow discharge chamber through said intake chamber, air flow passage, and discharging vent, and whereby when said pressure of water flowing through said cylindrical bore of the hollow discharge chamber increases still further, said conical moving plug seals said air flow passage between said hollow discharge chamber and said air flow passage of said external hood jacket.
