Abstract:
A multipurpose air fountain, comprising:an air blast gun having a blowpipe, said blowpipe having internal threads formed at an output end thereof;a versatile adapter having a first end threadedly engaged with said output end of said blowpipe, a second end of said versatile adapter having threads formed thereon; and,a spraying adapter threadedly engaged to said second end of said versatile adapter, said spraying adapter including:a. a splicing sleeve threadedly coupled to said versatile adapter;b. a nozzle valve having a fitting section formed on one end thereof and disposed in said splicing sleeve, a nozzle section formed on an opposing end of said nozzle valve, and a threaded portion intermediate said nozzle section and said fitting section, said nozzle valve having a through bore extending between said opposing ends thereof and said nozzle section has a pair of side-wind holes formed therein in open communication with said through bore;c. a nozzle carrier having an inlet opening formed on a first end coupled to said threaded portion of said nozzle valve and a an outlet nipple formed on an second end thereof, said nozzle carrier having a jet exhaust bore formed between said inlet opening and second ends thereof, at least a portion of said nozzle section of said nozzle valve being disposed in said jet exhaust bore and said side-wind holes being in open communication with said inlet opening, said nozzle carrier having a manifold formed on a side thereof, said manifold having a housing hole formed therein in open communication with said jet exhaust bore, said housing hole having a conically shaped portion connecting said housing hole to said jet exhaust bore, said nozzle carrier having a diversion hole extending between said inlet opening and said housing hole to provide passage of compressed air from said inlet opening to said housing hole;d. a fitting valve disposed in said housing hole adjacent said conically shaped portion, said fitting valve having a pair of spaced flange and an annular recess formed therebetween, said annular recess being disposed in aligned relationship with said diversion hole and one of said flanges having a plurality of openings formed therethrough to provide open communication between said annular recess and said conically shaped portion of said housing hole; and,e. a pipe fitting secured to said manifold in said housing hole, whereby a high suction is formed at said pipe fitting responsive to compressed air being passed through said nozzle section for drawing a fluid into said jet exhaust bore through said housing hole and spraying the fluid from said outlet nipple.
