Abstract:
A switch handle mounted at a bottom section of a sprayer long tube of a water sprayer, comprising a sprayer long tube, a switch and an inlet tube having a connecting sleeve pivotally connected to a bottom end of the switch, wherein a bottom section of the sprayer long tube is connected to an outlet section of the switch, and an inlet section of the switch is connected to the inlet tube having a suitable length, the sprayer long tube, switch and inlet tube being connected integrally, and a connecting section of the bottom section of the sprayer long tube and the switch, a periphery of the switch, a connecting section of the switch and the inlet tube, and an entire peripheral surface of the tube being injection molded integrally from plastic (or rubber) by injection molding one or two times, to thereby effectively couple them integrally such that the plastic (or rubber) injection molded parts are used by a handle provided at the bottom section of sprayer long tube, whereby the handle will not rotate or slide up and down, and the switch which controls water to flow into the sprayer long tube is disposed on a periphery of a front section of the handle which is mounted to a bottom section of the sprayer long tube so that the user uses the hand to hold the handle to directly manipulate the switch as in use; andwherein a plurality of water stopping annular grooves for fitting a plurality of water stop rings and a plurality of positioning annular grooves are formed on extending sections extending from inlet and outlet sections of the switch, and a front section of the inlet tube and the bottom section of the sprayer long tube are respectively fitted on the peripheries of the extending sections of the inlet and outlet sections of the switch, positioning rings are directly formed at positions corresponding to the positioning annular grooves provided on the extending sections, so that the front section of the inlet tube and the bottom section of the sprayer long tube are insertably coupled with the inlet and outlet sections, thereby achieving effective connection among the sprayer long tube, the switch and the inlet tube.
