Detailed Description of the Preferred Embodiment
[0021] As shown in FIGS. 2˜7-1, a pistol nozzle of the preferred embodiment of the present invention comprises the component parts, which are described hereinafter.
[0022] A main body 10 is provided at the front end of the top thereof with a head seat 11 fastened therewith. The head seat 11 is provided in the interior of the outer end thereof with a water outlet 12, a locating tube 13, and a fitting tube 14. The water outlet 12 is provided with a washer 121 fitted thereinto. A locating bolt 16 is fitted into the fitting tube 14 and a recovery spring 15.
[0023] A water emission cover 20 has an outer annular body 21 which is provided in the front side of the inner wall thereof with a plurality of ribs 22, which are arranged circularly at an interval and are connected with a face plate 23 smaller in diameter. The outer peripheral edge of the face plate 23 and the front side of the inner wall of the outer annular body 21 form a full flow hole 24. The inner side of the water emission cover 21 is provided with a recessed space 25. The face plate 23 is provided in the center with a through hole 26 which is in turn provided in the outer periphery with an inner annular mesh 27. The face plate is provided in the outer side with a plurality of emission holes 28 of various shapes, and an outer annular mesh 29, and two tubular bodies 30 and 31 corresponding to emission holes 28 and the through hole 26.
[0024] The emission holes 28 of the water emission cover 20 are provided with a special emission hole 32, which is formed by a protruded ring 321 and a guide body 322 which is provided with a pointed end 323 located in the protruded ring 321. The pointed end 323 is provided with a tapered rod 324, an annular body 325, a wing piece 326, and a passage 327. The water emission cover 20 is further provided with three partition areas 33, 34, and 35, each of which forms with the inner side of the face plate 23 a locating wall 331, 341, 351. The three locating walls are respectively provided with a recessed arcuate edge 332, 342, 352.
[0025] A water distribution disk 40 has an outer diameter equal to the inner diameter of the recessed space 25 of the inner side of the water emission cover 20. The water distribution disk 40 is provided in the outer side thereof with an annular side 41 and a recessed surface 42. The water distribution disk 40 is provided in the center thereof with a locating hole 43 which is in turn provided with an annular body 445 corresponding in location to the through hole 26 of the face plate of the water emission cover 20. The annular body 44 is provided in the inner wall with an arresting ring 45 smaller in inner diameter. The water distribution disk 40 is provided with a through hole 46 corresponding in location to said tubular body 30 and smaller in inner diameter than said tubular body 30. The water distribution disk 40 is further provided in the inner side with a plurality of recessed edges 47 which are arranged circularly. The water distribution disk 40 is fastened with the face plate of the water emission cover 20 by a high frequency wave process such that the wall of the water distribution disk 40 is intimately attached to the inner wall of the recessed space 25, and that the water distribution disk 40 and the water emission cover 20 are disposed on the outer end of the head seat 11, and further that the locating tube 13 is engaged with a bolt 60 via the locating hole 43 of the water distribution disk 40 and the through hole 26 of the water emission cover 20. The water distribution disk 40 is actuated by the water emission cover 20 to turn such that the through hole 46 of the water distribution disk 40 is in communication with the water outlet 12 of the head seat 11, thereby enabling water to be emitted from the emission holes 28. When the through hole 40 of the water distribution disk 40 is aligned with the water outlet 12 of the head seat 11, the water distribution disk 40 and the head seat 11 are located by the locating bolt 16.
[0026] The water distribution disk 40 is provided in the outer side with three protruded arcuate bodies 50, 51 and 52, which are corresponding in location and size to the recessed arcuate edges 332, 342 and 352 of the locating walls 331, 341 and 351 of the inner side of the face plate 23 of the water emission cover 20. The first arcuate body 50 is provided with a guide hole 501 facing the annular body 44 of the distribution disk 40. The third arcuate body 52 has one end which is provided with a protruded block 521 which becomes gradually greater in the direction toward the annular side 41 of the outer periphery of the water distribution disk 40. The protruded block 521 is hollow and provided with a guide hole 552. The arcuate bodies 50, 51 and 52 are provided with a guide slot 461 in communication with the guide holes 501, 511 and 522. When the outer side of the water distribution disk 40 is fastened with the inner side of the face plate 23 of the water emission cover 20, the full flow hole 24 of the face plate 23 is obstructed by the annular side 41 of the water distribution disk 40. The arcuate bodies 50, 51, and 52 of the water distribution disk 40 are fitted into the recessed arcuate edges 332,342, and 352 of the locating walls 331, 341, and 351 of the face plate 23. The tubular bodies 30 and 31 of the inner side of the face plate 23, and the locating walls 331, 341 and 351 are in intimate contact with the outer side of the water distribution disk 40. The through hole 46 of the water distribution disk 40, the guide slot 461, and the locating hole 43 are in communication with the tubular bodies 30 and 31. The guide hole 501 of the first arcuate body 50 of the water distribution disk 40 is in communication with the outer annular mesh 29 of the water emission cover 20. The guide hole 511 of the second arcuate body 51 is in communication with the inner annular mesh 27 of the water emission cover 20. The guide hole 522 of the third arcuate body 52 is in communication with the full flow hole 24 of the water emission cover 20.
[0027] The present invention is characterized by the water distribution disk 40 which is provided in the annular side 41 with a plurality of round holes 53 which are circularly arranged and are corresponding in location to the ribs 22 of the water emission cover 20. The round holes 53 are in communication with the guide hole 522 of the water distribution disk 40 by the annular slot 54 of the water distribution disk 40. The water distribution disk 40 is fastened with the water emission cover 20 by the high frequency wave process.
[0028] As shown in FIGS. 8 and 8-1, a water flow 1 is guided into the guide hole 522 via the through hole 461 of the water distribution disk 40. The water flow 1 is further guided into the full flow hole 24 of the water emission cover 20 via the annular slot 54 of the water distribution disk 40 and the round holes 53 of the annular side 41 of the water distribution disk 40. In light of the water distribution disk 40 being fastened with the water emission cover 20 by the high frequency wave process, the water flow 1 can not flow in reverse into the interior of the head seat 11, thereby allowing the water flow 1 to be emitted from the full flow hole 24. In light of the round holes 53 being aligned with the ribs 22 of the water emission cover 20, the water flow 1 is collided with the ribs 22 to spread out.
