Here, the number of the guide grooves 33 depends on the outer diameter and tooth number of the pinion 4.
Still further referring to FIG. 3B, the matching face of the pinion 4 with the rotating disk 3 close to the periphery is configured with a guide rod 41 operated in coordination with the guide grooves 33, and the side of the matching face opposite to the guide rod 41 is further configured with a guide convex arc 42 operated in coordination with the guide concave arc 34. Furthermore, a positioning rod 43 is formed on the middle of the pinion 4 between the guide rod 41 and guide convex arc 42, and an engagement seat 44 is formed on another side of the positioning rod 43.
Referring to FIG. 3, the positioning rod 43 of the pinion 4 is inserted in the positioning seat 35 and the guide rod 41 is extended in the guide groove 33 when the pinion 4 is operated in coordination with the rotating disk 3.
The water inclining support 5 is a post cover, where a partitioning plate 51 is formed in the middle thereof to divide it into a upper seat 52 and lower seat 53, Furthermore, a matching hole 54 is configured on the middle of the partitioning plate 51, and a projecting bar 55 in engagement with the engagement seat 44 of the pinion 4 is configured at one side of the matching hole 54 of the partitioning plate 51, where the rotating disk 3 and pinion 4 are accepted in the upper seat 52, and the impeller 6 in the lower seat 53, with inclined water inlets 56 being configured on the side wall of the lower seat 53.
Referring to FIG. 2, the impeller 6 has an axle 61 with an engagement hole 60, on the upper part of which a drive gear 62 for the engagement with the pinion 5 is configured, and a plurality of leaves 63 are formed on the lower part of the periphery of the axle 61.
Referring to FIG. 4, the rotor 7 is a water body configured with inclined water hole 71, i.e. the water hole 71 on the rotor 7 is formed a certain angle with the rotation axis of the rotor 7, and the upper end edge of the rotor 7 is formed with a driven gear 72 in engagement with the rotating disk gear 32.
Referring to FIG. 6, upon the assembly of the shower water rotating structure of the present invention, each rotor 7 is inserted in the water outlet 121 of the lower housing 12, and the impeller 6, water inclining support 5, pinion 4 and rotating disk 3 are successively mounted thereon from bottom to top, where the axle 61 of the impeller 6 is in movable engagement with the projecting rod 31 of the rotating disk 3; the gear 32 of the rotating disk 3 is in engagement with the driven gears 72; the drive gear 62 on the rotating shaft 61 is passed through the partitioning plate 51 of the water inclining support 5 to be in engagement with the pinion 4; and a pin 8 is passed through the matching through hole 30 of the rotating disk 3 to fix the water separating disk 2 to the lower housing 12.
Referring to FIGS. 6A to 6D, according to the present invention, upon shower, water flows into main body via the water inlet 111 of the upper housing 11 and is then guided by the water separating disk 3 to flow into the water inclining support 5 from the side face thereof. Thereafter, the water enters the lower seat 53 via the inclined water inlet 56 of the water inclining support 5 and impacts the impeller 6 to cause it to rotate. Further, the drive gear 62 of the impeller 6 drives the pinion 4 to rotate; the guide rod 41 is moved along the guide groove 33 of the rotating disk 3 upon the rotation of the pinion 4 to poke the rotating disk 3 to rotate; and the gear 32 of the rotating disk 3 drives the rotors 7 to rotate such that the spray emitted from the rotors 7 is then formed into rotating spray. Furthermore, the rotating disk 3 is stopped rotating when the guide rod 41 of the pinion 4 is rotated to the range of the deep seat 36 of the rotating disk 3 from the previous guide groove 33, and the guide rod 41 does not drive the rotating disk 3 to rotate until it slides into the next guide groove 33 in such a way to make the rotors 7 to output rotating spray of an intermittent pulse type, making a human body feel more obvious on the rotating spray.
In this embodiment, the gear ratio of the drive gear 62 of the impeller 6 and pinion 4 is set to 22:28, the one of the pinion 4 and gear 32 of the rotating disk 3 1:6, and the one of the gear 32 and driven gear 72 of the rotor 7 12:30 so that the total transmission ratio of the entire gear reduction mechanism is 240:11. In addition, the number of the guide groove 33 on the rotating disk 3 is set to 6, and the one of rotors 7 is set to 3.
Referring to FIG. 3, the guide rod 41 of the pinion 4 and the guide groove 31 of the rotating disk 3 are fit in a sliding way to form a sliding pair, while the guide concave arc 34 of the rotating disk 3 and the guide convex arc 42 of the pinion 4 play guide and stability roles when the guide rod 41 is being slid out of the guide groove 33. Furthermore, the constant rotation of the pinion 4 is changed to intermittent motion of the rotating disk 3; the pinion 4 rotates one turn, and the rotating disk 3 rotates one groove position, i.e. 60 degrees, where the rotating disk 3 is moved during 2⁄3 unit time and stopped during another 1⁄3 unit time if one turn rotation of the pinion 4 takes one unit time.
Referring to FIGS. 6A-1 to 6A-6, the pinion 4 drives the rotating disk 3 to rotate; the rotating disk 3 is rotated 1⁄6 turn if the pinion rotates one turn, while the pinion 4 has no action with the rotating disk 3 during 1⁄3 of each rotation, namely, the rotating disk 3 is in a static state, so that the rotating disk 3 is not rotated continuously but intermittently. Thereupon, the spray is sprayed out in a conically spiral shape when the rotor 7 is rotated because the rotating disk 3 drives the rotor 7 to rotate and the water hole 71 on the rotor 7 is formed a certain angle with the rotation axis of the rotor 7, and the spray is sprayed out along the axle center of the water hole 71 in a straight line shape when the rotor 7 is stopped.
The shower water rotating structure of the present invention outputs an spray with intermittent pauses and a conically spiral shape, which is between rotating water and massage water, having a more obvious pulsating and soft massage effect. Referring to FIG. 7, which shows a spray formation principle of the present invention, the original continuous output rotation is caused to change into an intermittent rotation because the pinion 4 driving the rotating disk 3 is an intermittent motion; the water flow is not rotated when the rotors 7 are stopped (see stopping point a in the figure), the rotors 7 being kept spraying out water at a certain angle at this time, and the water flow is rotated around the axis when the rotors 7 are rotated, the spray is in a rotation state (see the rotation state b in the figure) at this time.
To sum up, the present invention realizes spray having a pulsating rotating water effect, improving the massage effect of shower water and allowing shower to be more comfortable and relax by driving the pinion 4 adapted to push the rotating disk 3 to rotate intermittently with the impeller 6 and then driving the rotor 7 having the inclined water hole 71 with the rotating disk 3.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the claims or scope of the general inventive concept as defined by the appended claims and their equivalents.
