SHOWERHEAD ASSEMBLY WITH SEQUENTIALLY PULSING NOZZLE SETS

Abstract

A showerhead assembly is provided which includes an outer housing and inner housing. The inner housing includes a support disk and gear housing disk for housing a selector wheel having a slot. The outer housing includes the base and a faceplate having nozzle systems connecting to complementary orifices. Water enters the internal housing via a channel where it is further diverted by the diverter arms so as to impinge on a gear train's bladed rotor, causing the gear train's individual components to rotate. Upon the rotation of the selector wheel, the selector wheel's slot aligns with a selected orifice whereby water travels through and enters a corresponding nozzle system. This sequence continues, causing water to sequentially spray from individual nozzles in systematic intervals so as to create a strobe-like spray pattern.

DETAILED DESCRIPTION OF THE INVENTION

[0040] While the present invention is susceptible of embodiment in various forms, as shown in the Drawings, hereinafter will be described the presently preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the invention, and it is not intended to limit the invention to the specific embodiments illustrated.

[0041] With reference to FIGS. 1-14, the water spraying assembly of the present invention is illustrated as a showerhead assembly 1 which includes an outer housing structure 8 and inner housing structure 9. Preferably, the outer housing structure 8 comprises the showerhead housing base 3 and the showerhead faceplate 2 having four nozzle systems 12A-D. Even more preferably, the inner housing structure 9 includes two primary components: a support disk 20 and a gear housing disk 21. In addition, the inner housing structure 9 further comprises an internal cavity 22 between the support disk 20 and gear housing disk 21 wherein a gear train 23 resides and works as a unit with a plurality of nozzle systems 12A-D. As would be understood by those skilled in the art, the showerhead assembly may include any number of nozzle systems 12A-D. However, for explanation purposes and with reference to FIGS. 10A-10D, a preferred showerhead assembly is described herein as having four nozzle systems 12A-D.

[0042] The four nozzle systems 12A-D are incorporated onto the outer housing's circular showerhead faceplate 2 which covers the posterior portion 25 of the inner housing's gear housing disk 21. Even more specifically, the showerhead faceplate's four nozzle systems 12A-D include four ducts 70 formed into the faceplate's back side 72 which extend to the four nozzle outlet sets 71. Preferably, the various nozzle outlet sets 71 emit water in an alternating fashion so as to create a strobe-effect on the spray pattern and provide a more unique shower experience for the user.

[0043] Preferably, the showerhead assembly 1 includes a showerhead housing base 3 that is frustoconical in shape. Even more preferably, the showerhead assembly 1 includes a neck portion 4 which houses the conduit 5 and is connected to a water source 6. Further, the conduit 5 includes an inlet 7 threadably affixed to the water source pipe. The inlet 7 receives water from the water source 6 and transports such water to the internal housing structure's water channel 26 so as to convey such water to the nozzle systems 12A-D. The water channel 26 includes a first end 27 and second end 28. Specifically, the first end 27 is in fluid connection with the conduit's inlet 7 and the second end 28 is in fluid connection with the gear train 23, so as to facilitate the passage of water from the conduit 5 through the cavity 22.

[0044] In an illustrative embodiment, the inner housing 9 comprises a support disk 20 which is affixed to and secured onto the gear housing disk 21, thereby functioning as a support structure for the gear housing disk 21. The gear housing's posterior side 25 converges with the outer housing of the showerhead faceplate 2.

[0045] Additionally, the gear housing disk 21 includes an anterior side 24 and posterior side 25. Moreover, the anterior side 24 includes an internal cavity 22 having a gear train 23. Preferably, the internal cavity 22 is cuboid shaped. More preferably, the internal cavity 22 resides within the depressed nucleus of the gear housing disk's anterior side 24. The gear housing disk's posterior portion 25 is embedded with four sets of similarly shaped window orifices 50A-D. In the preferred embodiment, the four sets of window orifices 50A-D are trapezoidal in shape. In the even more preferred embodiment, the window orifices' 50A-D axes are parallel to or the same as the gear train's 23 axis. Further, each window orifice 50A-D is equidistant from neighboring window orifices 50A-D and reside separately within each of the large gear's four quadrants 60A-D. For example, window orifice 50A is embedded in large gear's quadrant 60A, window orifice 50B is embedded in large gear's quadrant 60B, window orifice 50C is embedded in large gear's quadrant 60C, and window orifice 50D is embedded in large gear's quadrant 60D. The window orifices 50A-D are configured so as to align in a complementary fashion with the four nozzle systems 12A-D embedded on the showerhead faceplate 2. For example, window orifice 50A is configured to align with nozzle system 12A, window orifice 50B is configured to align with nozzle system 12B, window orifice 50C is configured to align with nozzle system 12C, and window orifice 50D is configured to align with nozzle system 12D.

[0046] In a first embodiment illustrated in FIGS. 1-10, the gear train 23 includes three-wheel portions: a bladed rotor 30, pinion 31, and a slotted large gear 32. In the embodiment illustrated in FIGS. 2-3 and FIGS. 5-8, the bladed rotor 30 is a propeller. However, the bladed rotor may be any circular structure having blades and capable of being turned by the flow of water such as propeller, impellor or water wheel. Specifically, water flows through the water channel 26 upstream from the gear train 23 and passes through the bladed rotor 30, thereby causing the bladed rotor 30 to rotate in a counterclockwise direction. Even more specifically, the pinion 31 is meshed and oriented above the bladed rotor 30 so as to rotate in a clockwise direction upon counterclockwise rotation of the bladed rotor 30. Additionally, the large gear 32 is sufficiently in contact with the pinion 31 so as to gain momentum by its slight collision with the pinion 31 upon the pinion's 31 rotation. Specifically, the large gear 32 revolves in a clockwise direction as the pinion 31 rotates and water continues to impinge and flow through the entirety of the gear train 23.

[0047] In the first embodiment, the three-wheel portions are mounted by arbors 33 onto the internal cavity 22 so as to allow the gear train 23 to rotatably pivot as water passes through the compound gear mechanism. Moreover, the internal housing structure's 22 axis is parallel to or the same as the gear train's 23 axis. Preferably, the bladed rotor's 30 diameter is one half of the large gear's 32 diameter. Even more preferably, the bladed rotor's 30 diameter is one third of the large gear's 32 diameter so as to produce optimal water torque and speed.

[0048] As illustrated in FIGS. 5-8, the internal cavity 22 includes two diverter arms 34 that function as driving forces to propel water through the gear train 23. Accordingly, the diverter arms 34 are in fluid connection with the bladed rotor's 30 teeth and are positioned so as to optimally divert water flow. Specifically, the first diverter arm 35 is erected from the internal cavity 22 and is directly adjacent to the water channel's second end 28 and to the bladed rotor's 30 left side. Additionally, the second diverter arm 36 is erected from the internal cavity 22 and resides beneath the large gear 32, bordering the bladed rotor's 30 right side. This methodical configuration allows the diverter arms 34 to appropriately direct and modulate water flow through the internal cavity 22.

[0049] Moreover, the large gear 32 includes one slot 40 configured similarly to the window orifices 50A-D on the gear housing disk's posterior side 25 and resides along the same axis. Preferably, the slot 40 is the same shape and size as the window orifices 50A-D so as to allow the slot 40 to align with one window orifice 50A-D upon rotation of the large gear 32, thereby causing water to travel through the opening and exit the gear housing disk 21. The gear housing disk 21 is parallel and appended to the showerhead faceplate 2 in a manner which allows for water to be received via the nozzle ducts 70 and emit out of the nozzle outlets 71.

[0050] Specifically, the showerhead faceplate 2 comprises four nozzle systems 12A-D. Each nozzle system 12A-D includes a nozzle duct 70 having four nozzle outlets 70. In the preferred embodiment, the four nozzle systems 12A-D are configured in a spatially equidistant manner from neighboring nozzle systems 12A-D. Preferably, and as illustrated in FIGS. 9 and 10, one nozzle system 12A-D resides per each quadrant of the showerhead's faceplate 80A-D. For example, nozzle system 12A resides in showerhead faceplate's quadrant 80A, nozzle system 12B resides in showerhead faceplate's quadrant 80B, nozzle system 12C resides in showerhead faceplate's quadrant 80C, and nozzle system 12D resides in showerhead faceplate's quadrant 80D. Even more preferably, the nozzle ducts 70 are recessed within the showerhead's faceplate 2 while the nozzle outlets 71 project out of the showerhead's faceplate 2. Even more preferably, the nozzle ducts 70 are arranged directly above and adjacent to corresponding window orifices 50A-D on the gear housing disk 21. This configuration allows water received by the window orifice 50A-D to pass through a given nozzle duct 70 and project out of its respective nozzle outlets 71. Notably, the nozzle ducts 70 remain static in position as the gear train 23 revolves in the internal cavity 22. Water is received by a nozzle system 12A-D only upon alignment of the system's respective nozzle duct 70 with the large gear's slot 40. The gear train 23 functions as a unit with the nozzle systems 12A-D, selectively spraying water in consecutive intervals upon revolution of the large gear 32. Accordingly, each nozzle outlet 70 ejects water successively and rhythmically so as to create a strobe-effect spray pattern for the user.

[0051] In a second embodiment illustrated in FIGS. 11-14, the gear train includes only the selector wheel 32 which includes a plurality of blades 37 to form an impellor. Like the previous embodiment, the selector wheel 32 is rotatable upon an arbor 33 and includes a slot 40 having a shape that is the same or similar to the window orifices 50A-D in the support disk 21 so as to allow the slot 40 to align with one window orifice 50A-D upon rotation of the large gear 32.

[0052] Again, water flows through the water channel 26 into cavity 22 to pass through the selector wheel's blades 37. Water striking the blades 37 causes the selector wheel 32 to rotate. As the selector wheel 32 rotates, the selector wheel's slot 40 will selectively and sequentially align with one of the window orifices 50A-D to allow water pass to through a given nozzle duct 70 to sequentially spray out of its respective nozzle outlets 71.

[0053] While a preferred nozzle set and showerhead assembly 1 have been illustrated and described, it would be apparent that various modifications of the nozzle set and showerhead assembly 1 can be made without departing from the spirit and scope of the invention. Accordingly, it is not intended that the invention be limited except by the following claims. Having described my invention in such terms to enable a person skilled in the art to understand the invention, recreate the invention, and practice it, and having identified the presently preferred embodiments thereof, I claim:
