1. Field of the Invention
The invention relates to spouts and more particularly to a spout for sink, the spout being capable of flowing water out of peripheral nozzles by pressing a pivotal press button.
2. Description of Related Art
Conventional spouts for sink having a device for controlling water flow direction are well known. However, the switching mechanism of the device is complicated and its cost is expensive.
Thus, the need for improvement still exists.
It is therefore one object of the invention to provide a sink spout comprising a spray handle; a conduit disposed in the spray handle and including an inlet, a first outlet, a second outlet, and a tunnel disposed between the inlet and the first and second outlets and having a port communicating with the inlet; a nozzle assembly releasably secured to the spray handle and including a plurality of central nozzles and a plurality of peripheral nozzles; a central channel disposed in the spray handle and communicating with both the first outlet and the central nozzles respectively; a peripheral channel disposed around the central channel and communicating with both the second outlet and the peripheral nozzles respectively; a spring biased shank disposed in the tunnel and including an intermediate, annular recess and an enlargement at an end; a sleeve including an axial channel and two aligned through holes through an intermediate portion, the sleeve being positioned on an intermediate portion of the spring biased shank with the through holes communicating with the intermediate, annular recess; and a push button pivotably secured to the spray handle and including a receptacle on an inner surface with the enlargement positioned therein; wherein in a predetermined operating mode, the port communicates with the second outlet to establish a first flow path from the inlet to the central nozzles via the port, the second outlet, and the central channel; and wherein in response to pressing a portion of the push button aligned with the enlargement, the spring biased shank moves to block the second outlet and establish a second flow path from the inlet to the peripheral nozzles via the port, the intermediate, annular recess, the through holes, the first outlet, the peripheral channel.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
Referring to
A conduit 2 is provided in a space 11 of a spray handle 1. An annular nozzle assembly 6 is threadedly secured to an internally threaded opening of the spray handle 1. The nozzle assembly 6 includes a plurality of central nozzles 61 and a plurality of peripheral nozzles 62 around the central nozzles 61. A central channel 12 in the spray handle 1 communicates with the central nozzles 61. A peripheral channel 13 is provided around the central channel 12. The peripheral channel 13 and the central channel 12 are spaced apart. Further, the peripheral channel 13 communicates with the peripheral nozzles 62. The conduit 2 includes an inlet 21 and two outlets 22. A latch 221 is provided at an end of each outlet 22. The latches 221 are secured to the central channel 12 and the peripheral channel 13 respectively, thereby fastening the conduit 2 in the spray handle 1. One outlet 22 communicates with the central channel 12 and the other outlet 22 communicates with the peripheral channel 13 respectively. A tunnel 23 is provided at a joining portion of the outlets 22 and the inlet 21 and includes a port 231 communicating with the inlet 21. A pivot pin 24 is provided on an outer surface of the conduit 2. A stem 222 is provided on a blind end of the tunnel 23. A moveable shank 3 is provided in the tunnel 23 and includes a receptacle 31 at one end, an intermediate, annular recess 32, and a spherical enlargement 33 at the other end. A torsion spring 3A is provided in the receptacle 31. The stem 222 is partially disposed in the receptacle 31 to urge against the torsion spring 3A. A sleeve 4 includes an axial channel 41 and two aligned through holes 42 through an intermediate portion. The sleeve 4 is positioned on an intermediate portion of the moveable shank 3 with the through holes 42 communicating with the recess 32. A push button 5 is provided on an opening 14 of the spray handle 1 and includes a receptacle 51 on an inner surface with the enlargement 32 positioned therein, and a groove 52 on the inner surface with the pivot pin 24 pivotably disposed therein. Thus, the push button 5 is pivotal.
