  • Publication number: 20120145811
    Abstract: A spray head press structure for use of kitchen counters comprises a control valve mounted into an extensive conduit of a body and regulated via a press handle attached at the rear side of the body, and a locking collar secured to a threaded hole at the bottom of the body. The control valve includes a cross-shaped guidance end extending beneath a restrictive flange to mount to a spring element and flexibly conjoin to the locking collar. The locking collar has multiple water-intake orifices annularly arranged at the top surface and a central tubular positioning section for the transport of water into the body and the positioning of the guidance end respectively. Thus, the control valve can be linearly restricted in movement via the positioning section, and the upwards flush of the water and the descending control valve can be separated from each other, achieving smooth and effortless operation thereby.
