DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Referring to FIGS. 1 through 3 and 10, a diverter includes the body 1, an inlet module 2, a first outlet module 3, a second outlet module 5 and a control module 4 according to the preferred embodiment of the present invention. The body 1 is connected to the inlet module 2, the first outlet modules 3, the second outlet module 5 and the control module 4. Although not shown or described in detail, seals can be used to prevent leak.

The body 1 is made by injection molding. The body 1 includes a first tubular branch 11, a second tubular branch 12, a third tubular branch 13 and a fourth tubular branch 14. The tubular branches 11 to 14 are in communication with one another.

The inlet module 2 includes a collar 21 and a clip 22. The collar 21 is made by injection molding, and so is the clip 22. The collar 21 is used to connect a hose (not shown) to the body 1. The clip 22 is used to connect the collar 21 to the third tubular branch 13.

The first outlet module 3 includes a ring 31 and a nozzle 32. The ring 31 is made by injection modeling, and so is the nozzle 32. The ring 31 includes a central aperture 311 and peripheral apertures 312. The nozzle 32 includes a central outlet portion 321, a tubular wall 322 and a peripheral outlet portion 323. The central outlet portion 321 is located in the tubular wall 322. The peripheral outlet portion 323 extends around the tubular wall 322.

The ring 31 is inserted in the first tubular branch 11, around a central tube 111 formed in the first tubular branch 11. The nozzle 32 is provided around the first tubular branch 11. Thus, the central tube 111 includes a section inserted in the central aperture 311 and an edge abutted against an edge of the tubular wall 322, which extends around the central outlet portion 321. The central outlet portion 321 is aligned to the central aperture 311. The peripheral outlet portion 323 is aligned to the peripheral apertures 312. The nozzle 32 includes, on an internal face, a thread (not numbered) engaged with a thread (not numbered) formed on an external face of the first tubular branch 11, thereby connecting the nozzle 32 to the first tubular branch 11.

The control module 4 includes a controller 41 and a knob 42. The controller 41 is made by injection modeling, and so is the knob 42. The controller 41 is inserted in the fourth tubular branch 14. A screw 43 is used to rotationally connect the controller 41 to a tubular portion 17 formed in the fourth tubular branch 14. The controller 41 includes an insert 44 fitted in a bore 442 made in the knob 42 so that the controller 41 is rotatable with the knob 42. Referring to FIGS. 3 and 9, the insert 44 includes an anti-skid portion 441 in contact with an anti-skid portion (not numbered) formed on the wall of the bore 442 made in the knob 42, thereby keeping the insert 44 in the bore 42, and ensuring that the controller 41 be rotatable with the knob 42.

The second outlet module 5 includes a stationary hollow element 51, a rotational hollow element 52 and a joint 53. The stationary hollow element 51, the rotational hollow element 52 and the joint 53 are made by injection modeling. The stationary hollow element 51 includes a tubular portion 511 connected to the second tubular branch 12 by a clip 515. The rotational hollow element 52 includes a tubular portion 521 formed with a thread (not numbered) engaged with a thread (not numbered) formed on the joint 53. The joint 53 includes a reduced section inserted in a hose (not shown) in use. The rotational hollow element 52 is rotationally connected to the stationary hollow element 51 by an axle 531. The axle 531 is preferably a threaded bolt used with a washer. The rotational hollow element 52 is rotatable relative to the stationary hollow element 51 so that the angle of the joint 53 relative to the stationary hollow element 51 is changeable (FIG. 19). The stationary hollow element 51 includes a face formed with cavities 532. A spring-biased detent 533 is supported on a face of the rotational hollow element 52. When the rotational hollow element 52 is rotatable relative to the stationary hollow element 51, the spring-biased detent 533 enters and leaves the cavities 532 one after another so that the rotational hollow element 52 rattles on the stationary hollow element 51. Elastically, the spring-biased detent 533 is inserted in one of the cavities 532 to keep the rotational hollow element 52 in one of several angles relative to the stationary hollow element 51.

Referring to FIG. 4, a partition 15 is formed in the body 1. The partition 15 includes a first aperture 151, a second aperture 152 and a third aperture 153. The third tubular branch 13 is in communication with the fourth tubular branch 14 via a slot 16 made in the body 1. Hence, water is only allowed to go into the fourth tubular branch 14 and the control module 4 from the inlet module 2, which is connected to a faucet in operation. The partition 15 includes a tubular portion 17 for receiving the screw 43 that includes a section inserted in the controller 41 of the control module 4.

Referring to FIG. 5, the fourth tubular branch 14 is in communication with the central tube 111 of the first tubular branch 11 via the first aperture 151.

Referring to FIG. 6, the fourth tubular branch 14 is in communication with a peripheral zone 112 of the first tubular branch 11 through the second aperture 152.

Referring to FIG. 7, the fourth tubular branch 14 is in communication with the second tubular branch 12 via the third aperture 153.

Referring to FIGS. 8 through 10, a first flange 411 and a second flange 412 are formed on a side of the controller 41 of the control module 4 pointed at the partition 15 of the body 1. A water-containing zone 413 is a gap between the first flange 411 and the second flange 412. The water-containing zone 413 is in communication with the third tubular branch 13 via the slot 16. The second flange 412 includes an orifice 416 at a point other than a center of the second flange 412.

Referring to FIGS. 8, 10 and 11, a spring-biased detent 415 is supported on the periphery of the controller 41. A first recess 141, a second recess 142 and a third recess 143 are made in an internal face of the fourth tubular branch 14. The spring-biased detent 415 is elastically inserted in the first recess 141, the second recess 142 or the third recess 143 selectively.

Referring to FIGS. 12 and 13, the knob 42 is operable to switch the diverter between directions and modes for dispensing water. The knob 42 includes a water-column mark 422, a spray mark 423 and a hose mark 424 at an end.

The knob 42 is in a position where the water-column mark 422 is aligned to an indicator 18 formed on the body 1 (FIG. 1) and the spring-biased detent 415 is elastically inserted in the first recess 141. Now, the orifice 416 is in communication with the first aperture 151, the water-containing zone 413, the orifice 416, the first aperture 151, the first tubular branch 11, the central tube 111, the central aperture 311 and the central outlet portion 321, thereby providing a first channel. Thus, water goes into the central outlet portion 321 from the inlet module 2 through the third tubular branch 13, the slot 16, the water-containing zone 413, the orifice 416, the first aperture 151 and the central tube 111, which extends through the central aperture 311. Finally, the water goes out of the central outlet portion 321 via apertures (not numbered) made in the central outlet portion 321. The water goes leaves the central outlet portion 321 in the form of a column because the arrangement of the apertures in the central outlet portion 323 is relatively concentrated.

Referring to FIG. 14 through 16, the knob 42 is in another position where the spray mark 423 is aligned to the indicator 18 (FIG. 1) and the spring-biased detent 415 is elastically inserted in the second recess 142. Now, the orifice 416 is in communication with the second aperture 152, the water-containing zone 413, the orifice 416, the second aperture 152, the first tubular branch 11, the peripheral zone 112, the peripheral apertures 312 and the peripheral outlet portion 323, thereby providing a second channel. Thus, water enters the peripheral outlet portion 323 from the inlet module 2 through the third tubular branch 13, the slot 16, the water-containing zone 413, the orifice 416, the second aperture 152, the peripheral zone 112 and the peripheral apertures 312. Finally, the water goes out of the peripheral outlet portion 323 via apertures (not numbered) made in the peripheral outlet portion 323. The water goes out of the peripheral outlet portion 323 in the form of spray because the arrangement of the apertures in the peripheral outlet portion 323 of the nozzle 32 is relatively diverse.

Referring to FIGS. 17 and 18, the knob 42 is in another position where the hose mark 424 is aligned to the indicator 18 (FIG. 1) and the spring-biased detent 415 is elastically inserted in the third recess 143. Now, the orifice 416 is in communication with the third aperture 153, the water-containing zone 413, the orifice 416, the third aperture 153, the second tubular branch 12, a passage 514 made in the stationary hollow element 51 (in communication with the second tubular branch 12) and a passage 522 made in the rotational hollow element 52 (in communication with the passage 514 and the joint 53), thereby providing a third channel. Thus, water travels into the second tubular branch 12 from the inlet module 2 through the third tubular branch 13, the slot 16, the water-containing zone 413, the orifice 416 and the third aperture 153. Then, the water travels into the joint 53 from the second tubular branch 12 via the passage 514 and the passage 522. Finally, the water leaves the joint 53.

Referring to FIG. 19, the rotational hollow element 52 is rotatable to change the angle of the joint 53. Referring to FIG. 10, a first stop 512 and the second stop 513 are formed on a face of the stationary hollow element 51 pointed at the rotational hollow element 52. There is an angle of 180 degrees between the first stop 512 and the second stop 513. The rotation of the rotational hollow element 52 is limited to 180 degrees. The rotation of the rotational hollow element 52 reaches a limit when the spring-biased detent 533 abuts against the first stop 512. The rotation of the rotational hollow element 52 reaches another limit when the spring-biased detent 533 abuts against the second stop 513.

As discussed above, the control module 4 is operable to switch the diverter between directions and modes for dispensing water. Water goes from the first outlet module 3 as a water column, leaves the first outlet module 3 in water spray, or goes out of the hose, which is connected to the second outlet module 5. The components of the body 1, the inlet module 2, the first outlet module 3, the second outlet module 5 and the control module 4 are made by injection modeling. Hence, the production of the components is relatively easy. Moreover, the total number of the components is relatively small. Therefore, the assembly of the diverter is relatively easy and precise. Risks of leak are reduced. In addition, ultrasonic welding is not used so that the diverter can be taken apart for repair.

The present invention has been described via the illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims.
