Abstract:
1. A single-levered rotary pulling tap comprising a base fixed to a platform; a tap body including an internal space to communicate with an inlet rotatably installed to the base, an outlet, and an opening; a spraying head movably installed to the outlet of the tap body to be pulled outward and retracted backward; a control valve set including a sleeve to be fixed to the opening of the tap body, a valve core limited in the sleeve to rotate and including an internal passageway, and a lever to rotate the valve core; a first flowing assembly located in the tap body and including a seat and a column portion, the seat including a cold-water inflow channel, a hot-water inflow channel, and a passage, respectively having a cold-water coupling aperture, a hot-water coupling aperture, and a mouth arranged on a bottom end of the column portion, and individually having a cold-water orifice, a hot-water orifice, and an exit fixed on an outer wall of the column portion; a second flowing assembly located in the tap body and including a securing segment to couple with the sleeve of the control valve set and a bush segment movably fitted with the column portion of the first flowing assembly so as to rotate in relation to the column portion, the second flowing assembly including a cold-water inflow channel, a hot-water inflow channel and a passage, respectively having a cold-water vent, a hot-water ventilation, and an intake arranged on an end surface of the securing segment, and respectively having a cold-water orifice, a hot-water orifice, and an exit formed on an inner wall of the bush segment, on the inner wall of the bush segment being vertically provided a first slot, a second slot, and a third slot in order relative to the first, the second, and the third slots of the column portion of the first flowing assembly; and the cold-water orifice, the hot-water orifice, and the exit being located at the third, the second, and the first slots individually; an axial defining means located between the column portion of the first flowing assembly and the bush segment of the second flowing assembly so that the bush segment is axially limited to rotate on the column portion; a circumferential defining means to limit the tap body to rotate within a predetermined angular range relative to the base; a piping set including a cold-water receiving piping to connect with the cold-water coupling aperture of the first flowing assembly, a hot-water receiving piping to couple with the hot-water coupling aperture of the first flowing assembly, an outflow piping to connect with the mouth of the first flowing assembly, and a flexile hose, two ends of which couple with the spraying head and the outflow piping individually; wherein the axial defining means includes a circular dent, two cutouts, and two restricting bolts; wherein the circumferential defining means includes a rotor and two stators.
