Abstract:
1. A water sprayer, comprising: a housing; a guide member mounted in the housing and having a first portion formed with a water inlet connected to an outside of the housing and a second portion formed with a water outlet connected to the water inlet; a valve seat mounted in the second portion of the guide member and having a first portion formed with a water inlet hole connected to the water outlet of the guide member and a second portion formed with a first water outlet hole connected to the water inlet hole and a second water outlet hole connected to the water inlet hole; a nozzle unit mounted in the housing and having a first nozzle connected to the first water outlet hole of the valve seat, a connecting hole connected to the second water outlet hole of the valve seat and a second nozzle connected to the connecting hole; a valve shaft movably mounted on the guide member and having a first portion extended into the valve seat and formed with a stop portion; wherein the second nozzle of the nozzle unit is located at a central portion of the nozzle unit; the first nozzle of the nozzle unit surrounds a periphery of the second nozzle of the nozzle unit; the connecting hole of the nozzle unit is located and connected between the second nozzle of the nozzle unit and the second water outlet hole of the valve seat; the valve shaft is movable between a first position where the stop portion of the valve shaft closes a connection between the first water outlet hole and the water inlet hole of the valve seat and opens a connection between the second water outlet hole and the water inlet hole of the valve seat so that a water flow from the water inlet hole of the valve seat in turn flows through the second water outlet hole of the valve seat, the connecting hole and the second nozzle of the nozzle unit and is injected outward from the second nozzle of the nozzle unit, and a second position where the stop portion of the valve shaft opens the connection between the first water outlet hole and the water inlet hole of the valve seat and closes a connection between the second water outlet hole and the connecting hole of the nozzle unit so that the water flow from the water inlet hole of the valve seat in turn flows through the first water outlet hole of the valve seat and the first nozzle of the nozzle unit and is injected outward from the first nozzle of the nozzle unit; the water sprayer further comprises a restoring spring mounted on the valve shaft and biased between the stop portion of the valve shaft and the nozzle unit to push the stop portion of the valve shaft toward the valve seat to close the connection between the first water outlet hole and the water inlet hole of the valve seat and to open the connection between the second water outlet hole and the water inlet hole of the valve seat at a normal state.
