A sprinkler has a pushbutton assembly and a piston assembly. The sprinkler has a chamber defined to receive therein the piston assembly and the pushbutton assembly. The piston assembly is controlled by the pushbutton assembly to activate the communication between the chamber in the handle of the sprinkler and the inlet of the handle. The pushbutton assembly has a pushbutton movably received in the handle to control an engagement of a piston of the piston assembly to the chamber so as that the the water flow out of the outlet is controlled by the movement of the pushbutton.

1. A sprinkler comprising:a spray head; a handle having an inlet for connecting with a water source, an outlet selectively communicating with the inlet and engaged with the spray head and a chamber defined for receiving therein a piston assembly for controlling the communication between the inlet and the outlet; and a pushbutton assembly received in the chamber relative to the piston assembly for controlling actuation of the piston assembly, wherein a linkage is provided between the piston assembly and the pushbutton assembly to drive movement of a piston in the chamber, wherein the piston assembly further comprises: an abutting member for receiving therein a first distal end of the linkage after extending through the piston; a first spring a first end of which engages with the abutting member; and an outer cover threadingly engaged with the handle to cover a first opening of the chamber and to enclose the first spring, the abutting member and the piston in the chamber, and wherein the pushbutton assembly comprises: a tubular body threadingly engaged with the handle to cover a second opening of the chamber and having a flange formed on a distal end thereof to stop a sealing ring that is mounted around the tubular body and multiple positioning slots respectively defined in an internal periphery of the body; a pushbutton having an open end provided with an undulated edge and multiple positioning bosses formed near the undulated edge and corresponding to a respective one of the multiple positioning slots and a closed end inserted into and extending out of the tubular body; a rotation button movably received in the pushbutton and having multiple ribs formed on an outer periphery thereof to engage with the undulated edge of the pushbutton and detachably connected with the multiple positioning slots of the pushbutton; a second spring inserted in the rotation button and located around a tube in the rotation button; and a cover securely formed in the chamber and having a central opening and a seal enabling to allocate the above mentioned parts in one side of the chamber; wherein each of the ribs abuts a respective one of a plurality of inclined side faces of the undulating edge so that the rotation button is movably received in the pushbutton when the pushbutton is pushed.
