A sprayer device includes an opening formed by a peripheral wall, and a mouth for receiving water. A head is rotatably attached to the peripheral wall and includes a number of ports to be selectively aligned with the mouth, and to selectively receive water from the mouth. The head includes an outer peripheral portion having a number of apertures, a cover is secured to the head. A buffering plate is spaced from the cover to form a gap between the cover and the buffering plate. The cover includes one or more inlets for allowing the water to selectively flow through the inlets of the cover and flow into the gap formed between the cover and the buffering plate.

1. A sprayer device comprising:a sprayer body including an opening formed therein and defined by a peripheral wall, and including a mouth for receiving water, said sprayer body including a spring biased projection provided therein,a head rotatably attached to said peripheral wall of said sprayer body and including a plurality of ports formed therein and to be selectively aligned with said mouth of said sprayer body, to selectively receive water from said mouth of said sprayer body, said head including an outer peripheral portion having a plurality of apertures formed therein,a cover including a peripheral skirt extended therefrom and secured to said head, to form a chamber in said cover and said head, and including a plurality of holes formed therein and aligned with said ports of said head respectively, anda buffering plate received in said opening of said sprayer body and spaced from said cover, to form a gap between said cover and said buffering plate, andsaid cover including at least one inlet formed therein and communicating with said chamber of said cover and said head, to allow the water to selectively flow through said at least one inlet of said cover and flow into said gap formed between said cover and said buffering plate, and then to flow out through said apertures of said head, and said cover including a plurality of depressions formed therein for selectively receiving said spring biased projection, and for maintaining either of said holes of said cover in alignment with said mouth of said sprayer body.2. The sprayer device as claimed in claim 1, wherein said buffering plate includes an orifice formed therein and aligned with said mouth, and holes of said cover are arranged to be selectively aligned with said orifice of said buffering plate and said mouth of said sprayer body.3. The sprayer device as claimed in claim 2, wherein said sprayer body includes at least one rib provided therein, said buffering plate includes at least one slot formed by at least one flap to receive said at least one rib of said sprayer body, and to prevent said buffering plate from rotating relative to said sprayer body, and to maintain an alignment of said orifice of said buffering plate with said mouth of said sprayer body.4. A sprayer device comprising:a sprayer body including an opening formed therein and defined by a peripheral wall, and including a mouth for receiving water,a head rotatably attached to said peripheral wall of said sprayer body and including a plurality of ports formed therein and to be selectively aligned with said mouth of said sprayer body, to selectively receive water from said mouth of said sprayer body, said head including an outer peripheral portion having a plurality of apertures formed therein,a cover including a peripheral skirt extended therefrom and secured to said head, to form a chamber in said cover and said head, and including a plurality of holes formed therein and aligned with said ports of said head respectively,a buffering plate received in said opening of said sprayer body and spaced from said cover, to form a gap between said cover and said buffering plate,said cover including at least one inlet formed therein and communicating with said chamber of said cover and said head, to allow the water to selectively flow through said at least one inlet of said cover and flow into said gap formed between said cover and said buffering plate, and then to flow out through said apertures of said head, andsaid head including a plurality of barrels extended therefrom and aligned with and holes of said cover respectively.5. The sprayer device as claimed in claim 4, wherein said head includes a peripheral barrier extended therein to form an annular passage therein, and includes a number of perforations formed therein and communicating with said annular passage thereof, a first barrel of said barrels includes an outlet formed therein and communicating with said annular passage of said head, to allow the water to flow from said first barrel to said annular passage and to flow out through said perforations of said head.6. The sprayer device as claimed in claim 4, wherein said head includes at least one partition extended therefrom to couple said barrels together, and to form an intermediate channel and an outer channel in said head.7. The sprayer device as claimed in claim 6, wherein said head includes a plurality of orifices formed therein and communicating with said outer channel thereof, a first barrel of said barrels includes an outlet formed therein and communicating with said outer channel of said head, to allow the water to flow from said first barrel to said outer channel and to flow out through said orifices of said head.8. The sprayer device as claimed in claim 7, wherein said head includes a peripheral barrier extended therein to form an annular passage therein, and includes a number of perforations formed therein and communicating with said annular passage thereof, a second barrel of said barrels includes an outlet formed therein and communicating with said annular passage of said head, to allow the water to flow from said first barrel to said annular passage and to flow out through said perforations of said head.9. The sprayer device as claimed in claim 8, wherein said cover further includes two entrances formed therein for selectively communicating with either or both said first and said second barrels, to allow the water to flow out through either or both said annular passage and said perforations of said head or said outer channel and said orifices of said head.10. The sprayer device as claimed in claim 6, wherein said intermediate channel of said head is communicated with said at least one inlet of said cover, a first barrel of said barrels includes an outlet formed therein and communicating with said intermediate channel of said head, to allow the water to flow from said first barrel to said intermediate channel, and to flow out through said at least one inlet of said cover, and to flow into said gap formed between said cover and said buffering plate, and then to flow out through said apertures of said head.
