[0030] A casing 6 includes an outer thread 61 formed therein for threading with the inner thread 44 of the hood 4 and for securing to the hood 4, such that the casing 6 may also be rotated relative to the seat 5 and the sprayer body 2 with the hood 4 and the control ferrule 3. The casing 6 includes an inner threaded hole 69 formed therein, and includes a peripheral fence 68 extended into the threaded hole 69 thereof for forming a chamber 680 within the fence 68, and includes a bore 67 formed in the center portion thereof, and includes three or three pairs of ports 62, 63, 64 formed around the bore 67 of the casing 6 (FIG. 3) and formed or defined by cylindrical turrets 620, and includes a number of depressions 65 formed in the peripheral portion thereof for receiving the spring-biased projections 55 of the seat 5 and for adjustably securing the casing 6 to the seat 5 and thus to the sprayer body 2 at any selected angular position by the spring-biased projection 55. The ports 62 of the casing 6 are blind holes or are blocked. The peripheral fence 68 is engaged through the middle portion of the ports 63, 64. The ports 63 are communicated with the inner portion of the peripheral fence 68 (FIGS. 1, 3), and the other ports 64 are communicated with the outer portion of the peripheral fence 68 (FIGS. 3, 7, 8). The casing 6 includes a peripheral channel 60 formed therein, and includes a number of apertures 66 formed in the outer peripheral portion thereof and communicating with the peripheral channel 60 thereof.

[0031] A cover 70 is engaged onto the peripheral fence 68 of the casing 6 and includes one or more passages 71 and a center bore 73 formed therein for communicating with the bore 67 and the ports 62-64 of the casing 6. A block 8 is threaded in the threaded hole 69 of the casing 6, and includes a peripheral passageway 84 formed therein (FIGS. 2, 4-8), and includes a number of cavities 83 formed therein, such as formed around the peripheral passageway 84 of the block 8, and includes a number of outlets 81 formed therein and communicating with the cavities 83 thereof respectively, and includes a number of exits 82 formed therein and communicating with the peripheral passageway 84 thereof. A curved and slidable blocking member 87 is slidably received in the peripheral passageway 84 of the block 8 and includes one or more fins 871 extended therefrom. One or more ducts 88 and paddle wheels 89 are received in the cavities 83 of the block 8 respectively. The block 8 includes a pipe 85 extended rearward therefrom and engaged into the bore 73 of the cover 70 and the bore 67 of the casing 6 and communicating with the bore 53 of the seat 5. The block 8 includes a threaded hole 86 formed therein.

[0032] As best shown in FIGS. 9-11, a cap 10 is threaded to the threaded hole 86 of the block 8 and includes a bore 100 and an opening 103 formed therein, and includes a valve seat 101 formed therein, and includes one or more ears 102 extended outward therefrom, for allowing the cap 10 to be rotated relative to the block 8 and to be moved inward and outward of the threaded hole 86 of the block 8. A shaft 9 is received in the bore 100 of the cap 10 and includes a latch 92 provided in the rear end thereof for latching to the pipe 85 of the block 8 and thus for securing the shaft 9 within the threaded hole 86 of the block 8. The shaft 9 includes a tapered surface or a valve member 93 formed or provided in the front portion thereof for engaging with the valve seat 101 of the cap 10, and includes an extension 95 extended forward therefrom and a head 94 secured or provided on the free end of the extension 95. The head 94 has an outer diameter greater than that of the extension 95 and smaller than that of the shaft 9 for slidably engaged in the opening 103 of the cap 10. The shaft 9 includes a longitudinal groove 91 formed therein for allowing the water to flow out through the opening 103 of the cap 10 when the valve member 93 of the shaft 9 is disengaged from the valve seat 101 of the cap 10. The opening 103 of the cap 10 may be blocked when the valve member 93 of the shaft 9 is engaged with the valve seat 101 of the cap 10.

[0033] In operation, as shown in FIG. 2, when the casing 6 is rotated relative to the seat 5 to align the blocked ports 62 of the casing 6 with the openings 54 of the seat 5, and when the valve member 93 of the shaft 9 is engaged with the valve seat 101 of the cap 10, the water is blocked and may not flow out through the sprayer body 2.

[0034] As shown in FIG. 4, when the casing 6 is rotated relative to the seat 5 to align the ports 63 of the casing 6 with the openings 54 of the seat 5, the water from the openings 54 of the seat 5 may flow into the chamber 680 of the fence 68 and may flow through the passages 71 of the cover 70 and may flow into the peripheral passageway 84 of the block 8. The slidable blocking member 87 may thus be forced to slide along the peripheral passageway 84 of the block 8 by the water such that some of the exits 82 of the block 8 may be changeably or alternatively blocked by the blocking member 87, and such that the water may be caused to flow out through some of the exits 82 of the block 8 alternatively.

[0035] As shown in FIG. 5, when the ports 63 of the casing 6 are partially communicating with the openings 54 of the seat 5, i.e., the cylindrical turret 620 of the port 63 is engaged with the middle portion of the opening 54 of the seat 5, or the opening 54 of the seat 5 is not completely aligned within the turret 620 of the port 63, a portion of the water from the openings 54 of the seat 5 may also flow into the peripheral passageways 84 of the block 8 and may flow out through some of the exits 82 of the block 8 alternatively. The other portion of the water from the openings 54 of the seat 5 may flow into the peripheral channel 60 of the casing 6 and may thus flow out through the apertures 66 of the casing 6.

[0036] As shown in FIG. 6, when the ports 62, 63, 64 of the casing 6 are disengaged from the openings 54 of the seat 5, the water from the openings 54 of the seat 5 may only flow into the peripheral channel 60 of the casing 6 and may thus flow out through the apertures 66 of the casing 6.

[0037] As shown in FIG. 7, when the casing 6 is further rotated relative to the seat 5 to partially align the ports 64 of the casing 6 with the openings 54 of the seat 5, a portion of the water from the openings 54 of the seat 5 may also flow into the peripheral channel 60 of the casing 6 and may thus flow out through the apertures 66 of the casing 6. The other portion of the water may flow through the ports 64 of the casing 6 and may flow through the gap formed between the casing 6 and the peripheral fence 68 and may bypass the cover 70 and may flow into the cavities 83 of the block 8. The paddle wheels 89 may be rotated or propelled by the water flowing into the cavities 83 of the block 8 such that the water may intermittently flow out through the outlets 81 of the block 8.

[0038] As shown in FIG. 8, when the casing 6 is further rotated relative to the seat 5 to completely align the ports 64 of the casing 6 with the openings 54 of the seat 5, the water may only flow through the ports 64 of the casing 6 and may only intermittently flow out through the outlets 81 of the block 8 via the paddle wheels 89 that are rotatably received in the cavities 83 of the block 8.

[0039] As shown in FIG. 2, when the casing 6 is further rotated relative to the seat 5 to align the blocked ports 62 of the casing 6 with the openings 54 of the seat 5 again, the water is blocked and may not flow out through the sprayer body 2.

[0040] Referring next to FIGS. 9-11, when the cap 10 is rotated relative to the block 8, the valve member 93 of the shaft 9 may be gradually moved away from the valve seat 101 of the cap 10, in order to change the outward flow of the water through the opening 103 of the cap 10. The conventional sprayer devices have not rotatable or adjustable cap provided or threaded to the front portion of the sprayer device for adjusting the outward flow of the water.

[0041] Accordingly, the sprayer device in accordance with the present invention includes various kinds of outward water flows.

[0042] Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
