Abstract

A spray nozzle includes a rod extended from a casing which has two inlets. A follower is rotatably engaging with the rod and has a barrel aligned with one inlet and has one or more cylindrical members aligned with the other inlet. A board and a cap are secured to the rod. A control ferrule may rotate the follower and the disc to align either of the inlets with the barrel and the cylindrical members. The water is allowed to flow out through a peripheral gap formed between the control ferrule and the cap. The spray nozzle includes a greatly simplified configuration.

Claims

1. A spray nozzle comprising:

a casing including a mouth for connecting said casing to a water reservoir, said casing including a rod extended therefrom, said rod including a free end,

a plate secured to said casing and including a center portion engaged on said rod, said plate including a first inlet and a second inlet, said second inlet being arranged closer to said center portion of said plate than said first inlet,

a follower including a center portion rotatably engaging with said rod and including a barrel for aligning with said second inlet and including at least one first cylindrical member for aligning with said first inlet,

a disc secured to said follower and rotatably engaging with said rod, said disc including an opening for engaging with said barrel and including at least one orifice for engaging with said first cylindrical member,

a board secured to said free end of said rod and including a protrusion having at least one passage formed therein, said protrusion being allowed to be aligned with said opening, said board including an entrance for aligning with said orifice,

a cap including a peripheral portion secured to said board and including a plurality of punctures formed therein, said cap including an outlet for aligning with said entrance and for aligning with said orifice, and

a control ferrule including a peripheral portion secured to said follower so as to rotate said follower and said disc,

said follower and said disc being rotated by said control ferrule so as to align said second inlet with said barrel and so as to align said first inlet with said first cylindrical member, water contained in said casing being allowed to flow out of said punctures of said cap when said protrusion is aligned with said opening and said barrel and said second inlet, and the water being allowed to flow out of said orifice when said outlet of said cap and said entrance and said first inlet are aligned with said first cylindrical member.

2. A spray nozzle according to claim 1, wherein said plate includes a hole formed therein for receiving projection means, said projection means includes a ball and a spring for biasing said ball to engage with said follower so as to position said follower relative to said casing.

3. A spray nozzle according to claim 1, wherein said follower includes a peripheral wall having a plurality of notches formed therein, said control ferrule includes a peripheral flange and includes a peripheral gap formed between said peripheral flange of said control ferrule and said cap and communicating with said notches of said follower, said follower includes a second cylindrical member for aligning with said first inlet, said second cylindrical member including a plurality of slits formed therein for allowing water to flow into said follower when said second cylindrical member is aligned with said first inlet, and for allowing the water to flow out through said peripheral gap.
