Abstract:
A water nozzle comprising:a main body provided with a head seat, said head seat being provided with a water outlet, a locating tube, and a fitting tube, said water outlet provided with a leakproof ring, said fitting tube provided in the interior thereof with a locating bolt having a recovery spring;a nozzle cover having an outer annular body which is provided in an inner wall thereof with a plurality of ribs, said ribs being separated from one another and connected to a face plate, said face plate and said outer annular body being provided therebetween a plurality of peripheral flow holes, said nozzle cover further provided in an inner side thereof with a recessed space, said face plate provided in a center thereof with a through hole and a number of center jet holes, said face plate further provided with a plurality of jet holes circumventing said center jet holes, a plurality of peripheral jet holes, and a plurality of tubular bodies;a water distribution disk equal in outer diameter to said face plate of said nozzle cover and having in the periphery thereof an annular side and a recessed surface, said water distribution disk provided in the center thereof with a locating hole and an annular body corresponding in location to said through hole of said face plate of said nozzle cover, said annular body having a stop ring, said water distribution disk further provided with a plurality of through holes corresponding in location to said tubular bodies of said face plate of said nozzle cover, said water distribution disk further provided in a periphery of an inner side thereof with a plurality of recesses which are arranged in a circle, said water distribution disk being joined with said face plate of said nozzle cover such that said locating tube of said head seat is put through said locating hole of said water distribution disk and said through hole of said nozzle cover, and that said locating tube is fastened onto by a bolt via said through hole of said nozzle cover, said water distribution disk being linked with said nozzle cover such that said water distribution disk is actuated by said nozzle cover in motion to turn so as to enable said plurality of through holes of said water distribution disk to be in communication with said water outlet of said head seat, and that said water distribution disk is located by said recesses in conjunction with said locating bolt which is engaged with one of said recesses;wherein one of said plurality of jet holes of said nozzle cover is are provided with a special jet hole formed integrally by a flow guiding body of a protruded ring, said flow guide body having a pointed end which is located in the interior of said protruded ring and is provided with a tapered rod having an annular body jutting out of said protruded ring, said tapered rod being provided with two wings which are connected to an inner wall of said protruded ring such that a channel is formed between an outer wall of said tapered rod and the inner wall of said protruded ring, said plurality of jet holes further provided therebetween with at least a first separation area, a second separation area, and a third separation area, said first separation area provided with a first locating wall connected to an outer wall of said tubular bodies, said second separation area provided with a second locating wall connected to the outer wall of said tubular bodies, said third separation area provided with a third locating wall connected to the outer wall of said tubular bodies, said first locating wall provided with a first arcuate edge, said second locating wall provided with a second arcuate edge, said third locating wall provided with a third arcuate edge;wherein said water distribution disk is provided with a first arcuate body corresponding to said first arcuate edge of said first locating wall, a second arcuate body corresponding to said second arcuate edge of said second locating wall, and a third arcuate body corresponding to said third arcuate edge of said third locating wall, said first arcuate body provided with a first flow guiding hole facing said annular body of said water distribution disk, said second arcuate body provided with a protuberance--having a second flow guide hole--, therefore, this change facing said annular side of said water distribution disk, said first arcuate body provided with a first guide slot in communication with said first flow guiding hole, said second arcuate body provided with a second guide slot in communication with said second flow guiding hole, said third arcuate body provided with a third flow guiding hole whereby said water distribution disk is joined with said face plate of said nozzle cover such that said peripheral jet holes of said face plate and said peripheral flow holes of said face plate are separated by said annular side of said water distribution disk, and that said first arcuate body, said second arcuate body and said third arcuate body of said water distribution disk are engaged respectively with said first arcuate edge, said second arcuate edge, and said third arcuate edge, and further that said plurality of through holes, of said water distribution disk are in communication with said tubular bodies of said nozzle cover, thereby enabling said first flow guiding hole of said first arcuate body of said water distribution disk to be in communication with said center jet holes of said nozzle cover, said second flow guiding hole of said second arcuate body of said water distribution disk being in communication with said peripheral flow holes of said nozzle cover, said third flow guiding hole of said third arcuate body being in communication with said peripheral jet holes of said nozzle cover.
