A water sprayer includes a handle having a passage, a housing having a pathway and a chamber communicating with the passage and a passageway communicating with the chamber and the pathway of the housing, to form a valve seat between the passageway and the pathway of the housing. A stem is rotatably and slidably received in the passageway and the chamber of the housing, and includes a block having a groove for selectively communicating with the passage of the handle. The block includes a channel formed by a swelling and having an opening selectively communicating with the pathway of the housing when the stem is rotated relative to the housing, to control a water flowing through the housing.

I claim: 1. A water sprayer comprising: a handle including a passage formed therein, for coupling to a water reservoir, a housing provided on top of said handle, and including a pathway formed therein, said housing including a chamber formed therein and communicating with said passage of said handle, and including a passageway formed therein and communicating with said chamber and said pathway of said housing, to form a valve seat between said passageway and said pathway of said housing, a stem rotatably and slidably received in said passageway and said chamber of said housing, and including a front end extendible out through said housing, and including a rear end, and including a block provided thereon and having a groove formed therein for selectively communicating with said passage of said handle when said stem moves rearwardly relative to said housing, and for being selectively offset from said passage of said handle when said stem moves forwardly relative to said housing, said block including a channel formed therein and defined by a swelling, and communicating with said groove thereof, and having an opening selectively communicating with said pathway of said housing when said stem is rotated relative to said housing, in order to control a water flowing through said pathway of said housing, said swelling of said stem being rotatable relative to said valve seat of said housing, to control the water flowing from said passageway to said pathway of said housing, and to allow the water to flow out through said pathway of said housing in different flowing quantity, a hand grip pivotally attached to said housing, and engageable with said front end of said stem, to selectively move said front end of said stem rearwardly relative to said housing when said hand grip is pulled toward said handle, and to allow said front end of said stem to move out through said front hole of said housing when said hand grip is released, means for biasing said stem forwardly relative to said housing, to disengage said groove of said block from said passage of said handle, and a knob attached to said rear end of said stem, to rotate said stem relative to said housing, and to rotate said swelling of said stem relative to said valve seat of said housing. 2. The water sprayer as claimed in claim 1, wherein said passageway of said housing includes a front hole formed therein, to slidably receive said front end of said stem. 3. The water sprayer as claimed in claim 1, wherein said groove of said block is perpendicular to said block of said stem. 4. The water sprayer as claimed in claim 1, wherein said groove of said block is inclined relative to said block of said stem. 5. The water sprayer as claimed in claim 1, wherein said channel of said block is parallel to said block of said stem. 6. The water sprayer as claimed in claim 1, wherein said block includes a curved recess formed therein and defined by said swelling, said housing includes a projection extended into said passageway thereof, and slidably received in said curved recess of said block, to limit said stem to rotate relative to said housing. 7. The water sprayer as claimed in claim 1, wherein said housing includes a cap attached thereto, to block said chamber thereof, a barrel slidably received in said chamber thereof and attached to said rear end of said stem, to allow said stem to be rotated in concert with said barrel, said biasing means includes a spring engaged between said barrel and said block.
