A water sprayer includes a housing, a control valve, a valve seat, a nozzle unit, a valve shaft, and a control button. Thus, the first nozzle and the second nozzle of the nozzle unit provide two different water spraying modes so that the water is injected outwardly from the nozzle unit in two different spraying modes according to a user's requirements, thereby enhancing the versatility of the water sprayer. In addition, the water sprayer is switched between two different spraying modes by pressing of the control button, thereby facilitating the user operating the water sprayer.

The invention claimed is: 1. A water sprayer, comprising: a housing; a control valve mounted in a first end of the housing and having an inside formed with a water inlet channel which has a first end protruded outwardly from the housing and a second end provided with a valve chamber which has a first side formed with a first water conduit connected to the water inlet channel and a second water conduit connected to the water inlet channel; a valve seat mounted in the valve chamber of the control valve and having a side formed with a water inlet hole connected to the water inlet channel of the control valve and a peripheral wall formed with a water outlet hole connected to the water inlet hole and the second water conduit of the valve chamber; a nozzle unit mounted in a second end of the housing and having a first nozzle connected to the first water conduit of the valve chamber and a second nozzle connected to the second water conduit of the valve chamber; a valve shaft movably mounted in the valve seat and having a first end provided with a dividing disk movable in the valve chamber of the control valve and located between the first water conduit of the valve chamber and the water inlet hole of the valve seat and a second end protruded outwardly from the housing; a control button pivotally mounted on the housing and rested on the second end of the valve shaft to control movement of the valve shaft; wherein the control valve has a peripheral wall formed with a screw bore, the valve seat has a peripheral wall formed with a protruding extension plate formed with a through hole, and the water sprayer further comprises a locking screw extended through the through hole of the valve seat and screwed into the screw bore of the control valve to attach the valve seat to the control valve. 2. The water sprayer in accordance with claim 1, wherein the valve shaft is movable between a first position where the dividing disk of the valve shaft opens a connection between the first water conduit of the valve chamber and the water inlet channel of the control valve and closes a connection between the water inlet hole of the valve seat and the water inlet channel of the control valve so that water from the water inlet channel of the control valve in turn flows through the first water conduit of the valve chamber into the first nozzle of the nozzle unit and is injected outward from the first nozzle of the nozzle unit, and a second position where the dividing disk of the valve shaft opens the connection between the water inlet hole of the valve seat and the water inlet channel of the control valve and closes the connection between the first water conduit of the valve chamber and the water inlet channel of the control valve so that the water from the water inlet channel of the control valve in turn flows through the water inlet hole and the water outlet hole of the valve seat and the second water conduit of the valve chamber into the second nozzle of the nozzle unit and is injected outward from the second nozzle of the nozzle unit. 3. The water sprayer in accordance with claim 2, wherein the control valve has an end portion formed with an inner enclosure located under the valve chamber and connected to the first water conduit of the valve chamber and an outer enclosure located under the valve chamber and connected to the second water conduit of the valve chamber. 4. The water sprayer in accordance with claim 3, further comprising a mounting sleeve mounted between the control valve and the nozzle unit and connected between the first water conduit of the valve chamber and the first nozzle of the nozzle unit. 5. The water sprayer in accordance with claim 4, wherein the mounting sleeve is received in the outer enclosure of the control valve and has an inside formed with a mounting hole mounted on and connected to the first nozzle of the nozzle unit and a top wall formed with a protruding mounting portion inserted into the inner enclosure of the control valve. 6. The water sprayer in accordance with claim 5, wherein the mounting portion of the mounting sleeve has an inside formed with a connecting hole connected to the mounting hole and the first water conduit of the valve chamber. 7. The water sprayer in accordance with claim 6, wherein when the valve shaft is movable to the first position, the water from the valve chamber of the control valve in turn flows through the first water conduit of the valve chamber, the connecting hole of the mounting portion and the mounting hole of the mounting sleeve into the first nozzle of the nozzle unit and is injected outward from the first nozzle of the nozzle unit. 8. The water sprayer in accordance with claim 2, further comprising a restoring spring mounted on the valve shaft and biased between the dividing disk of the valve shaft and the first side of the valve chamber of the control valve to push the dividing disk of the valve shaft toward the valve seat to open the connection between the first water conduit of the valve chamber and the water inlet channel of the control valve and to close the connection between the water inlet hole of the valve seat and the water inlet channel of the control valve. 9. The water sprayer in accordance with claim 8, wherein when the valve shaft is movable to the second position, a water pressure from the water inlet channel of the control valve overcomes an elastic force of the restoring spring, so that the water from the water inlet channel of the control valve is injected outwardly from the second nozzle of the nozzle unit constantly. 10. The water sprayer in accordance with claim 1, wherein the valve seat has an inside formed with a shaft hole to allow passage of the valve shaft. 11. The water sprayer in accordance with claim 10, wherein the water inlet hole of the valve seat is spaced from the first water conduit of the valve chamber and connected to the shaft hole. 12. The water sprayer in accordance with claim 1, wherein the valve seat has a peripheral wall formed with an annular seal portion rested on an open outer side of the valve chamber of the control valve to seal the valve chamber of the control valve. 13. The water sprayer in accordance with claim 1, wherein the control valve has a peripheral wall formed with a substantially spherical pivot base, and the control button has a first end formed with a substantially spherical pivot recess pivotally mounted on the pivot base of the control valve. 14. The water sprayer in accordance with claim 13, wherein the control button has a second end formed with a press portion rested on the second end of the valve shaft. 15. The water sprayer in accordance with claim 1, wherein the housing has a peripheral wall formed with an elongated slot to receive the control button. 16. The water sprayer in accordance with claim 1, wherein the first end of the housing is formed with a stepped through hole to retain the control valve. 17. The water sprayer in accordance with claim 1, wherein the second end of the housing is formed with an inner thread, and the nozzle unit has an outer thread screwed into the inner thread of the housing. 18. The water sprayer in accordance with claim 1, wherein the valve chamber of the control valve is extended in a direction perpendicular to an axial direction of the control valve and has a mediate portion connected to the water inlet channel of the control valve. 19. The water sprayer in accordance with claim 1, wherein the second nozzle of the nozzle unit is enclosed around and located outside of the first nozzle.
