1. An adjustable water sprayer comprising:
- a substantially hollow main body having a front edge provided with an assembling seat, said assembly seat including an annular, slantwise arched embedding ring;
a spray cup having a spray surface, provided with a plurality of netted holes and a plurality of spaced nozzles, and an inner wall surface, said inner wall surface terminating in an annular opening rim provided with a plurality of circumferentially and substantially equally spaced lock walls that protrude radially inwardly therefrom, said inner wall surface further including a plurality of locating slots spaced thereabout, each of said locating slots being positioned a predetermined distance and angle with respect to a respective one of said spaced nozzles;
a spray cup having a spray surface, provided with a plurality of netted holes and a plurality of spaced nozzles, and an inner wall surface, said inner wall surface terminating in an annular opening rim provided with a plurality of circumferentially and substantially equally spaced lock walls that protrude radially inwardly therefrom, said inner wall surface further including a plurality of locating slots spaced thereabout, each of said locating slots being positioned a predetermined distance and angle with respect to a respective one of said spaced nozzles;
a connector member provided with a conduit terminating in a radially extending, annular partition board, said conduit defining a longitudinal central axis and including a reduced diameter valve opening and a water outlet, said water outlet opening into said partition board at a position radially offset from the longitudinal central axis of said conduit, said partition board having a diameter substantially equal to the diameter of the inner wall surface of said spray cup and being provided with a packing ring groove about said water outlet; and
a packing ring positioned in said packing ring groove, wherein said connector member is received within said main body with said partition board abutting the front edge of said main body and said spray cup is connected to said main body by passing the lock walls through the embedding ring and pinching said connector member therebetween such that rotation of said spray cup with respect to said main body and connector member enables water flowing through said conduit and out said water outlet to flow through selective ones of said plurality of netted holes and spaced nozzles at various water pressures.
