[0003] The technology disclosed in this article mainly relates to shower heads, and more specifically to pulsating shower heads. Background Technology

[0004] Showering provides an alternative to bathing in a bathtub. Typically, a showerhead is used to direct water from the household water supply to the user for personal hygiene purposes.

[0005] In the past, bathing was the overwhelmingly popular choice for personal hygiene. However, in recent years, showering has become increasingly popular for several reasons. First, showering typically takes less time than bathing. Second, showering usually uses far less water than bathing. Third, shower stalls and bathtubs with shower heads are generally easier to maintain. Fourth, showering tends to result in less soap scum buildup. Fifth, when showering, the bather doesn't sit in dirty water—the dirty water is constantly rinsed away.

[0006] With the increasing popularity of showering, the number of shower head designs and manufacturers has also increased. Many shower heads spray pulsating water in a so-called "massage" mode. Other shower heads are called "drenching" shower heads because they have relatively large panels and spray water in a steady, gentle spray pattern. In some cases, the pulse of a traditional massage mode may not be as strong as consumers expect, especially when the water flow rate may be reduced (e.g., due to water consumption regulations). Therefore, shower heads with improved massage modes may be needed.

[0007] The information contained in the Background section of this specification, including any references cited herein and any descriptions or discussions thereof, is contained for technical reference purposes only and should not be considered as subject matter to be limited to the scope of this invention. Summary of the Invention

[0008] The shower head disclosed herein has a hydrodynamic turbine, a cam, and an on / off switch. The on / off switch is connected to the turbine and the cam, thereby oscillating across multiple sets of nozzle outlet holes in the massage shower head.

[0009] Another embodiment includes a device comprising a turbine attached to a cam, wherein the turbine is operably connected via a linkage to two or more opening and closing devices. Movement of the turbine causes the opening and closing devices to oscillate across multiple sets of nozzle outlet orifices.

[0010] Another embodiment includes a shower head comprising a housing defining: a chamber in fluid communication with a fluid inlet (such as a water source); a first row of nozzles; and a second row of nozzles. The shower head also includes a massage mode assembly at least partially received within the chamber. The massage mode assembly includes: a turbine; a cam connected to or integrally formed with the turbine; and an on / off switch connected to the cam. Through the configuration of the massage mode assembly, movement of the on / off switch is restricted to a single axis, such that as the turbine rotates, the cam causes the on / off switch to alternately fluidly connect and disconnect the first and second rows of nozzles from the fluid inlet.

[0011] Another embodiment of this disclosure includes a method for generating a massage spray pattern for a shower head. The method includes: fluidly connecting a first plurality of nozzles to a fluid source, wherein each of the first plurality of nozzles is substantially simultaneously opened; and fluidly disconnecting the first plurality of nozzles from the fluid source, wherein each of the first plurality of nozzles is substantially simultaneously closed.

[0012] Another embodiment of this disclosure includes a shower head having a spray head, an engine, and a panel. The engine is fluidly connected to a water source and is received within the spray head. The engine may include a massage mode assembly having a turbine and a shoe connected to the turbine, wherein movement of the shoe is restricted to a single axis. As the turbine rotates, the shoe alternately fluidly connects and disconnects a first set and a second set of nozzle orifices, wherein each nozzle within a particular set is opened and closed substantially simultaneously. Additionally, the panel is connected to the engine and configured to selectively rotate the engine to alter the spray characteristics of the shower head.

[0013] In one embodiment, a shower head is disclosed, comprising: a first nozzle; a second nozzle; and a massage mode assembly in fluid communication with a fluid inlet, the first nozzle, and the second nozzle. The massage mode assembly includes: a turbine; a cam coupled to the turbine to define a dwell edge extending between a leading bend and a following bend; and an on / off switch movably coupled to the cam, wherein movement of the turbine causes the cam to drive the on / off switch between a first position and a second position, wherein in the first position the on / off switch covers the nozzle and opens the second nozzle, and in the second position the on / off switch opens the first nozzle and covers the second nozzle.

[0014] In another embodiment, a massage mode assembly for a shower head is disclosed. The massage mode assembly includes: a turbine; an on / off switch; and a cam coupled to the turbine and the on / off switch. The cam includes a three-lobed surface for coupling to the on / off switch, wherein movement of the turbine causes the cam to rotate, thereby causing the on / off switch to move between a first position and a second position.

[0015] In yet another embodiment, a method is disclosed for generating a massage spray for a shower head. The method includes: engaging the wall of an on / off switch to initiate movement of the switch from a first position to a second position within a massage mode chamber; engaging the wall of the on / off switch to complete the movement of the switch to the second position within the massage mode chamber; fixing the switch in the second position with at least 10 degrees of rotation of a turbine coupled to and configured to move the switch within the massage mode chamber; and releasing the switch from the second position.

[0059] This disclosure relates to a shower head that includes a pulsating or massage spray. The shower head may include a massage mode assembly comprising a jet disc, a turbine, an on / off switch, and a housing. The massage mode assembly is used to generate a pulsating or intermittent spray. In one embodiment, the turbine defines one or more cams or cam surfaces, and the on / off switch (which may be restricted in certain directions) follows movement of the cams to generate a pulsating effect by selectively blocking and not blocking the outlet nozzle.

[0060] In operation, the water flowing through the shower head causes a turbine to rotate, and as the turbine rotates, a cam rotates, causing the on / off switch to oscillate. In examples where the movement of the on / off switch is constrained in one or more directions, the on / off switch may move in a reciprocating motion, such as back-and-forth motion, rather than a continuous motion. This reciprocating motion allows a first set of nozzles to be covered by the on / off switch while a second set of nozzles is not covered, and as the on / off switch reciprocates, it moves to close the second set of nozzles while the first set is open. In many embodiments, the nozzles in the two sets may not be open or "on" simultaneously. In particular, nozzles from the first set of nozzles may be closed while nozzles from the second set are open, and vice versa. Therefore, the shower head may not include a set of "transition" nozzles, i.e., a set of nozzles, where the nozzles in a set gradually open and close, for example, due to the rotating on / off switch.

[0061] The dual functionality of massage or pulsation modes allows the showerhead to generate stronger fluid force during pulsation mode, allowing users to experience a more intense "massage" sensation, even at lower fluid flow rates. In some cases, the pulsation mode can be up to 50% stronger than the pulsation mode of a traditional "progressive" pulsation showerhead. Therefore, compared to a conventional showerhead, this can potentially save more water while avoiding a reduction in force performance and actually allowing users to experience greater force during massage mode.

[0062] In some embodiments, the pulsating shower head spray can be formed by an oscillating on / off device. The on / off device can be configured to oscillate openings through a discrete set of shower nozzles. As an example, the on / off device can be actuated by one or more eccentric cams attached to or integrally formed with a water-driven turbine. These elements include one or more on / off devices operating oscillatingly, a turbine having one or more cams, and two or more sets of separate water outlet nozzles. Other embodiments may also include a linkage between the cams and the on / off device.

[0063] In some embodiments, to increase massage intensity, such as to compensate for reduced water flow rate and / or improve the user experience, the massage mode component may include a cam with two or more discrete edges or corners (as opposed to a circular or continuous edge cam). In these cases, one edge of the cam may be configured as a dwelling or retaining edge, which serves to help retain the opener / closer in a first position, even as the cam continues to rotate. The dwelling edge may define a dwell time, in which the opener / closer “pauses” in a first or second position to increase the time one or more nozzles are open and closed, respectively, which increases the water flow velocity leaving these nozzles, thereby increasing the force. In this way, the massage pulses can be more intense and the pulses can be more “distinctive” or more recognizable to the user compared to a continuous edge cam.

[0064] In some cases, the cam can be configured as a three-lobe or three-edge cam with at least two distinct edges and / or one or more corners. In these cases, one lobe or edge can be configured to initiate movement of the opener / closer, while the second lobe or edge can be configured to maintain the position of the opener / closer. Additionally, corners such as leading corners can be used to complete movement of the opener / closer to a first or second position.

[0065] With reference to the accompanying drawings, embodiments of the shower head of this disclosure will now be discussed in more detail. Figure 1A and Figure 1B These are various views of the shower head. Figure 2 yes Figure 1A An exploded view of the shower head. Figure 3 and Figure 4 yes Figure 1A A cross-sectional view of the shower head. (Reference) Figures 1A to 2 The shower head 100 may include a handle 102 and a spray head 104. Figures 1A to 2 In the embodiment shown, the shower head 100 is a handheld shower head. However, in other embodiments (e.g., see...), the shower head 100 is a handheld shower head. Figure 23 In this shower head 100, the shower head 100 can be a fixed or wall-mounted shower head, in which case the handle 102 can be omitted or its size reduced. The handle 102 defines an inlet 108 of the shower head 100, which receives water from a fluid source (such as a hose, J-pipe, etc.). Depending on the water source, the handle 102 may include a thread 106 or another connection mechanism for securing the handle 102 to a hose, pipe, etc.

[0066] In embodiments where the shower head 100 is a handheld shower head, the handle 102 may be an elongated member with a generally circular cross-section, or otherwise constructed to be comfortably held in the user's hand. Additionally, as... Figure 2 As shown, the shower head 100 may also include a flow regulator 160 and a filter 162 connected to the handle 102.

[0067] refer to Figure 1A and Figure 1B The shower head 104 includes a plurality of output nozzles arranged in multiple sets or groups, such as a first nozzle group 110, a second nozzle group 112, a third nozzle group 114, and a fourth nozzle group 116, which serve as outlets of the shower head 100. As will be discussed in more detail below, each selected nozzle group 110, 112, 114, 116 may be associated with different patterns of the shower head 100. Additionally, some nozzle groups, such as the fourth nozzle group 116, may include subsets of nozzles, such as a first nozzle row 120 and a second nozzle row 122. In this example, the two nozzle rows 120, 122 may be crescent-shaped, comprising five nozzles, and may be positioned relative to each other. However, Figure 1A and Figure 1B The examples shown are merely illustrative, and many other embodiments are conceivable. For example, nozzle rows 120, 122 may be arranged as one or more nozzles in a parallel line or other arrangement. The shower head mode is changed by rotating a mode selector 118, which in turn rotates the engine 126 received within the shower head 104, as will be discussed in more detail below.

[0068] refer to Figure 2 The shower head 100 may include an engine 126 having multiple deflectors 146, 158, 146, a massage mode assembly 152, and additional mode-changing components. The engine 126 is received within the shower head 104, and a cover 150 encloses the engine 126 within the shower head 104 and provides an aesthetically pleasing appearance for the shower head 100. Figure 5 This is the rear axonometric drawing of the cover plate. (Reference) Figure 1A , Figure 2 and Figure 5 The cover plate 150 is configured to generally correspond to the front end of the shower head 104 and may be a generally circular body. The cover plate 150 defines a plurality of orifices, such as nozzle orifices 178 and drain orifices 180a, 180b. As will be discussed below, these orifices 178, 180a, 180b receive nozzles from the nozzle assemblies 110, 112, 114, 116 forming the shower head 100. Therefore, the nozzle orifices 178 and drain orifices 180a, 180b can be provided in shapes, sizes, and positions corresponding to the number and position of the patterned nozzles.

[0069] The cover 150 forms a cup-shaped structure on the rear side defining a cover chamber 172. The cover chamber 172 may be configured to receive one or more components of the engine 126. A plurality of alignment brackets 174 define the periphery of the cover chamber 172 and extend upward from an inner bottom wall 184. The alignment brackets 174 may have a curvature substantially matching the curvature of the periphery of the cover 150 and are spaced apart from each other around the periphery. In one embodiment, the shower head cover 150 may include seven alignment brackets 174. However, the number of brackets 174 and the spacing between the brackets 174 may vary based on the diameter of the cover 150, the number of patterns of the shower head 100, and other factors. Additionally, although a plurality of alignment brackets 174 are shown, in other embodiments, the cover 150 may include a single outer wall defining the periphery of the cover chamber 172. Each alignment bracket 174 may include a bracket aperture 176 defined therethrough.

[0070] refer to Figure 5 The alignment bracket 174 can be spaced apart from the top edge of the edge 186 forming the rear end of the cover plate 150. The spacing between the bracket 174 and the top edge of the edge 186 defines the gap 188.

[0071] The inner bottom wall 184 of the cover 150 may include a central region 190 that is further recessed than the rest of the bottom wall 184. The central region 190 may be located in the central area of ​​the cover 150. A disc-shaped recess 182 may be formed at the center point of the central region 190. The recess 182 is located below the inner surface of the central region 190 and extends outward beyond the outer surface of the central region 190. The mode selector 118 may be a finger grip that is integrally formed with the cover 150 and extends outward from the edge 186.

[0072] Panel 148 will now be discussed in more detail. Figure 6A and Figure 6B These are the front and back perspective views of panel 148. Figure 14This is a cross-sectional view of panel 148 and mist plug ring 156. Panel 148 includes a front surface 192 and a rear surface 194. Front surface 192 defines a plurality of outlets 198, 200 and nozzles for selecting nozzle assemblies 112, 114. Depending on the desired spray characteristics for each mode of shower head 100, outlets 198, 200 and nozzles 112, 114 may be protrusions with a central outlet, orifices formed through panel 148, etc. For example, nozzles for a second nozzle assembly 112 may include protrusions extending outward from front surface 192 of panel 148, and nozzle chambers 226 may be included on rear surface 194. Nozzle chambers 226 may be formed as individual cylindrical cavities converging toward nozzle outlets. Each nozzle chamber 226 may include an internal shelf 228 defined toward the bottom end of chamber 226. The internal shelf 228 reduces the diameter of the chamber 226 before the nozzle outlet, which can be formed as a mist outlet 422 defined by the shelf 228 at the bottom of the chamber 226.

[0073] Continue to refer to Figure 6A , Figure 6B and Figure 14 Panel 148 may include a raised platform 194 extending outward from a central region of panel 148. Platform 194 may include two curved sidewalls 202 facing each other and two straight sidewalls or edges 204 connecting the two curved sidewalls 202. The raised platform 194 also includes a small piece 196 extending outward from the center of platform 194. Two nozzle rows 120, 122 are defined as curved protrusions on the top of platform 194. In this example, the two nozzle rows 120, 122 are curved to form opposing bracket shapes facing each other, with the small piece 196 located between the two rows 120, 122. Rows 120, 122 may generally match the curvature of the curved sidewalls 202 of platform 194. Each row 120, 122 may include a plurality of outlets 198. In one example, each row 120, 122 may include five outlets 198; however, the number of outlets 198 and the location of the outlets may be varied based on the desired output characteristics of the shower head 100.

[0074] Nozzle assemblies 112 and 114 can be formed as concentric rings around platform 194. In this way, rows 120 and 122 can form the innermost nozzle ring for shower head 100, while the remaining nozzle assemblies 110, 112, and 114 surround rows 120 and 122.

[0075] refer to Figure 6BThe panel 148 may also include a peripheral wall 206 extending outward from the peripheral edge of the outlet surface 194. The peripheral wall 206 forms the outer wall of the panel 148. The panel 148 may include a plurality of concentric annular walls 230, 232, 234, which, together with the peripheral wall 206, define a plurality of flow paths 212, 214, 216, 218. For example, a first annular wall 230 extends upward from the back surface 194 of the panel 148 but is positioned closer to the center of the panel 148 than the outer peripheral wall 206. The gap between the peripheral wall 206 and the first annular wall 230 defines a first flow path 212 and includes a first set of outlets 200. As another example, the first annular wall 230 and the second annular wall 232 define a second flow path 214 including a second nozzle assembly 112, and the second annular wall 232 and the third annular wall 234 define a third flow path 216. When panel 148 is connected to other panels of shower head 100, flow paths 212, 214, 216, 218 defined by various walls 206, 230, 232, 234 correspond to the discrete pattern of fluid channels in shower head 100. It should be understood that during assembly, walls 206, 230, 232, 234 prevent fluid from one flow path 212, 214, 216, 218 from reaching the outlet and / or nozzle in another flow path. The shape and position of the walls can be varied based on the desired pattern of the shower head.

[0076] The third annular wall 234 defines the fourth flow path 218 and the massage chamber 220. The massage chamber 220 is configured to receive the massage mode assembly 152, as will be discussed in more detail below. The massage chamber 220 may include an annular wall 236 concentrically aligned and positioned against the third annular wall 234. However, the annular wall 236 is shorter than the third annular wall 234, thus defining a shelf within the massage chamber 220.

[0077] The bottom surface of the massage chamber 220 includes two corner walls 222. The corner walls 222 extend toward the center of the chamber 220 and include straight edges that change the geometry of the bottom end of the chamber 220. The two corner walls 222 are opposite each other to transform the bottom end of the chamber 220 into a rectangle or truncated circle with a curved end. The corner walls 222 generally correspond to the straight edge 204 of the platform 194 on the front surface 192 of the panel 148.

[0078] A pin recess 224 is defined at the center of the chamber on the bottom surface and extends into the back of the small piece 196. The pin recess 224 is configured to receive and secure a pin from the massage mode assembly 152, as discussed in more detail below. Additionally, the nozzle outlet 198 of each row 120, 122 is defined along a portion of the bottom surface of the massage chamber 220.

[0079] Engine 126 may also include an inner panel 158. The inner panel 158 may define additional modes of the shower head. However, in embodiments where fewer modes may be desired, the inner panel may be omitted. Figure 7A and Figure 7B The front and rear views of the inner panel 158 are shown respectively. (Reference) Figure 7A and Figure 7B The inner plate 158 may be a generally circular plate with a diameter smaller than that of the front panel 148. The inner plate 158 may include a plurality of tabs 258 extending outwardly from the sidewalls of the inner plate 158. Massage orifices 252 are formed through the center of the inner plate 158, giving the inner plate 158 a ring or donut shape. Similar to the front panel 148, the inner plate 158 may include a plurality of walls defining multiple flow paths. For example, the inner plate 158 may include an outer peripheral wall 242 along the outer periphery of the plate 158 and first and second annular walls 244, 246 concentrically defined within the peripheral wall 242. The peripheral wall 242 and the first and second annular walls 244, 246 extend from both the front surface 238 and the rear surface 240 of the inner plate 158. The peripheral wall 242 and the first and second annular walls 244 and 246 form closed concentric circles on the front surface 238. Peripheral wall 242 and first annular wall 244 define a first flow path 248, and first annular wall 244 and second annular wall 246 define a second flow path 250. Each of the flow paths 248, 250 includes orifices 254, 256 extending through the front surface 238 and rear surface 240 of the inner plate 158. As will be discussed in more detail below, the flow paths 248, 250 and the corresponding orifices 254, 256 fluidly connect to a selected nozzle assembly based on a selected mode of the shower head 100.

[0080] refer to Figure 7BThe inner plate 158 may include a first finger 260 and a second finger 262 that project into a pattern aperture 252 on the rear side of the inner plate 158. As will be discussed in more detail below, the fingers 260, 262 provide structural support for the pattern selection component and help guide water to the desired fluid path. The first finger 260 is fluidly connected to a second flow path 250. On the rear surface 240 of the inner plate 158, the second finger 262 includes a plurality of separating walls 264, 266, 268 that intersect with one or more of the outer wall 242, the first annular wall 244, and / or the second annular wall 246. For example, the first separating wall 264 bisects the second finger 262 to define a first portion 270 and a second portion 272. The first separating wall 264 intersects the outer wall 242. The second separation wall 266 is defined on the outer edge of the second finger 262 and intersects both the outer wall 242 and the first annular wall 244 to fluidly separate the first flow path 248 from the first portion 270 of the second finger 262. Similarly, a third separation wall 268 is formed on the edge of the second finger 262 opposite to the second separation wall 266. The third separation wall 268 intersects with the inner wall of the inner plate 158 defining the massage orifice 252 and the second annular wall 246. In this way, the third separation wall 268 fluidly separates the second portion 272 of the second finger 262 from the second flow path 250.

[0081] The backplate 146 for the shower head 100 will now be discussed in more detail. Figure 8A and Figure 8B These are the top and bottom views of the back panel 146. (Reference) Figure 8A and Figure 8B The back plate 146 has a back side 276 and a front side 278. A peripheral wall 296 extends outward from the back side 276 at an angle, then transitions to a cylindrical shape extending perpendicular to the front side 278. In embodiments where the peripheral wall 296 is angled, the back side 276 of the back plate 146 may have a truncated cone or partially conical shape (see [link to documentation]). Figure 2 and Figure 8A The back panel 146 may include a plurality of tabs 280 extending outwardly and spaced apart from each other on the outer surface of the peripheral wall 296. The construction of the back panel may be modified based on the connection with the shower head, as discussed in more detail below.

[0082] refer to Figure 8AA locking band 282 is formed on the back side 276 of the back plate 146. The locking band 282 includes a plurality of locking fingers 318. The locking fingers 318 are spatially separated from each other and configured to function as fasteners for connecting the back plate to the mounting plate 144, as discussed in more detail below. The locking fingers 318 are separated from each other such that the locking fingers 318 will be more flexible than a solid material band to allow the fingers 318 to buckle and elastically return to their initial position. The locking fingers 318 may include a lip 320 extending from the front sidewall (see...). Figure 4 The locking strap 282 is defined in a generally circular shape on the back side 276.

[0083] Continue to refer to Figure 8A The back panel 146 may also include a plurality of braking recesses 292 defined on the back side 276. In one embodiment, there may be seven braking recesses 292; however, the number of recesses 292 may be based on the desired number of patterns of the shower head 100. Thus, the number of braking recesses 292 may also change as the number of patterns changes. The back panel 146 may also include a stop protrusion 294 extending upward from the back side 276. The stop protrusion 294 may be slightly trapezoidal, having a curved inner surface facing the center of the back panel 146.

[0084] Continue to refer to Figure 8A The back panel 146 includes a plurality of pattern openings 284, 286, 288, and 290. The pattern openings 284, 286, 288, and 290 are slightly triangular openings and are positioned adjacent to each other. Each of the openings 284, 286, 288, and 290 may correspond to one or more patterns of the shower head 100, as will be discussed below. In some embodiments, the pattern openings 284, 286, 288, and 290 may include a plurality of support ribs 322 extending longitudinally across each opening to form a plurality of sets of openings.

[0085] refer to Figure 8B The back panel 146 may include a plurality of annular walls 298, 300, 302 extending outward from the front side 278. Similar to other panels of a shower head, the annular walls 298, 300, 302 of the back panel 146 may be substantially concentrically aligned and may have a reduced diameter, wherein the combination of the annular walls defines a flow path for the back panel 146. Specifically, the outer peripheral wall 296 and the first annular wall 298 define a first flow path 310, the first annular wall 298 and the second annular wall 300 define a second flow path 312, the second annular wall 300 and the third annular wall 302 define a third flow path 314, and the third annular wall 302 defines a fourth flow path 316.

[0086] Similar to the inner plate 158, the back plate 146 may include a plurality of separation walls 304, 306, 308 that fluidly separate flow paths 310, 312, 314 from each other. In one embodiment, the back plate 146 may include: a first separation wall 304 that intersects with a first annular wall 298 to fluidly separate the first flow path 310 from the second flow path 312; a second separation wall 306 that intersects with a second annular wall 300 and a third annular wall 302 to separate the second flow path 312 from the third flow path 314; and a third separation wall 308 that intersects with the second annular wall 300 and the third annular wall 302 to separate flow path 316 from other flow paths. In this embodiment, the third annular wall 302 can transition into a separation wall 324, which is used to separate the fourth flow path 316 from the first flow path 310. Separation walls 304, 306, 308, and 324 are configured to separate each of the pattern orifices 284, 286, 288, and 290; thus, the thickness of separation walls 304, 306, 308, and 324 can be partially determined by the separation distance between each pattern orifice 284, 286, 288, and 290.

[0087] Mounting plate 144 connects engine 126 to shower head 100. Figure 9A and Figure 9B The top and bottom views of mounting plate 144 are shown. (Reference) Figure 9A and Figure 9B The mounting plate 144 may include a top surface 326 and a bottom surface 328. A rounded edge 330 extends outward from the bottom edge of the top surface 326. The rounded edge 330 has a larger diameter than the top surface 326 and may be substantially planar. A plurality of supports 332 extend upward at an angle between the sidewalls of the top surface 326 and the rounded edge 330, thereby providing support for the top surface 326 of the mounting plate 144.

[0088] refer to Figure 9A The mounting plate 144 may include an elliptical engagement wall 338 extending upward from a top surface 326. The engagement wall 338 extends across the width of the top surface 326. Two parallel sidewalls 340, 342 are positioned within the engagement wall 338 along its longitudinal sides. The sidewalls 340, 342 are parallel to each other and spaced apart from the inner surface of the engagement wall 338. An engine inlet 336 is defined as an opening through the top surface 326 of the mounting plate 144. The engine inlet 336 is defined at one end of the engagement wall 338 and surrounded by the engagement wall 338. The mounting plate 144 may further include a plurality of fastening orifices 334 defined at various locations on the top surface 326.

[0089] refer to Figure 9BMounting plate 144 may include a sealing cavity 350 defined by a wall extending upward from bottom surface 328. The sealing cavity 350 may have a slightly trapezoidal shape, but one of its walls is slightly curved. Engine inlet 336 is located within the sealing cavity 350. Mounting plate 144 may also include two spring posts 346, 348 extending downward from bottom surface 328. Spring posts 346, 348 are located on opposite sides of engine inlet 336 and may be formed on the bottom surface of the two parallel sidewalls 340, 342 at the top of mounting plate 144.

[0090] Continue to refer to Figure 9B The mounting plate 144 may further include a stop cavity 344 defined as a semi-circular cavity in the central region of the bottom surface 328. The stop cavity 344 may be configured to correspond to the shape of the stop protrusion 294 of the back plate 146, allowing the stop protrusion 294 to be received therein. A brake pin cavity 342 may be defined on the side of the bottom surface 328 opposite to the sealing cavity 350. The brake pin cavity 342 may have a generally cylindrical volume.

[0091] Massage mode component 152 will now be discussed in more detail. Figure 10 This is a top perspective view of the massage mode component 152. Figure 11 It is along Figure 10 The cross-sectional view of the massage mode component 152 is taken from line 11-11. Figure 12 yes Figure 10 Axonometric view of the bottom of massage mode component 152. (Reference) Figure 2 , Figure 10 and Figure 11 The massage mode assembly 152 may include a jet plate 164, a pin 168, a turbine 166, and an opener / closer 170. Each of these components will be discussed in turn below.

[0092] The spray plate 164 forms the top of the massage mode assembly 152 and may be a generally planar disk having a plurality of inlet sprayers 354, 356, 358. The inlet sprayers 354, 356, 358 are upwardly extending protrusions and are angled relative to the top surface 352 of the spray plate 164. Each inlet sprayer 354, 356, 358 includes an inlet orifice 366 providing fluid communication through the spray plate 164. A plurality of pressure orifices 362 may be defined through the spray plate 164 and spaced apart from the inlet sprayers 354, 356, 358.

[0093] refer to Figure 10 and Figure 11 The spray plate 164 may also include an anchor post 360 extending upward from the top surface 352. The anchor post 360 may be at least partially hollow to define a cavity configured to receive the pin 168 (see [link]). Figure 11 Additionally, the spray plate 164 may include an edge 364 extending upward from the top surface 352 along the outer peripheral edge of the top surface 352.

[0094] The turbine 166 of the massage mode component 152 will now be discussed. Figure 13A and Figure 13B These are various views of a turbine. A turbine 166 may be a generally hollow, end-opening cylinder with blades 368 extending radially inward from a generally circular turbine wall 380 toward a central hub 378. In some embodiments, the turbine wall 380 or a portion thereof may be omitted. Additionally, although eight blades 368 have been shown, a turbine 166 may include fewer or more blades 368. A turbine 166 may include a pin-shaped protrusion 374 that generally extends through the hub 378. The pin-shaped protrusion 374 may extend slightly upward from the upper side of the turbine 166 and slightly downward from the lower side of the turbine 166. A pin orifice 376 extends longitudinally through the pin-shaped protrusion 374, and the diameter of the pin orifice 376 corresponds to the diameter of the pin 168.

[0095] The turbine 166 may also include an eccentric cam 372 on its lower side (i.e., the downstream side of the turbine 166). The cam 372 is eccentrically positioned from the hub 378 and integrally formed with the turbine 166. In one embodiment, the cam 372 includes a cylindrical disk offset from the center of the turbine 166. In other embodiments, the cam 372 may be constructed in other ways and may be a separate component attached to or otherwise fixed to the turbine 166.

[0096] refer to Figure 12 The opener / closer 170 will now be discussed in more detail. The opener / closer 170, or shoe, includes an opener / closer body 382 having a cam orifice 384 defined therethrough. The opener / closer body 382 is a solid material segment (except for the cam orifice 384), and when positioned above an outlet, it allows the opener / closer 170 to selectively block fluid flow toward those outlets. The cam orifice 384 may be a generally elliptical orifice defined by an inner sidewall 386 of the opener / closer body 382. The width of the cam orifice 384 is chosen to substantially match the diameter of the cam 372 of the turbine 166. However, the length of the cam orifice 384 is greater than the diameter of the cam 372.

[0097] Continue to refer to Figure 12The opener / closer 170 may be a generally planar disk having a generally elliptical body 382 but with two parallel constraint edges 388, 390 formed at opposite ends. Specifically, the opener / closer body 382 may have two relatively straight constraint edges 388, 390 formed at opposite ends and two curved edges 392 formed on opposite sides. In one embodiment, the curved ends 392 form longitudinal edges of the opener / closer body 382, ​​while the constraint edges 388, 390 form transverse edges. However, in other embodiments, the opener / closer 170 may be constructed in other ways (see, for example...). Figure 18 ).

[0098] As mentioned above Figure 2 Briefly, the shower head 100 may also include a mist plug ring 156. The mist plug ring 156 generates mist output from the nozzles of the shower head 100, particularly the second nozzle assembly 112. (Reference) Figure 2 and Figure 14 The mist plug ring 156 may include a plurality of mist plugs 418 interconnected on the ring 420. Each mist outlet 422 in the second nozzle assembly 112 may have one mist plug 418. The mist plug 418 may have a “Z” shape, configured to sit on portions of the sidewall of the mist nozzle chamber 226, but not fill the entire chamber 226. Specifically, a stepped or slotted edge on either side of the mist plug 418 provides a gap between the sidewall of the chamber 226 and the mist plug 418, thereby allowing water to flow into the chamber 226 and through the outlet 422. As will be discussed in more detail below, the mist plug 418 creates a modified fluid flow within the mist chamber 226, which produces the atomized water characteristic.

[0099] In some embodiments, the change in geometry within the mist chamber 226 caused by the shape of the mist plug 418 can be achieved by altering the geometry of the mist chamber 226 itself. That is, the mist chamber 226 can be modified such that it incorporates a geometry that alters one or more characteristics of the fluid flow through the chamber, such as inducing rotation to produce desired water output characteristics. However, it should be noted that the manufacturing cost of the shower head 100 in embodiments where the change in geometry of the mist chamber 226 is due to the inserted mist plug ring 156 is lower than that in cases where the geometry change is accomplished by altering the chamber itself.

[0100] The mode selection component 408 will now be discussed in more detail. Figure 15 yes Figure 2 A magnified view of a portion of the exploded view, showing the mode selection component 408. (Reference) Figure 15The mode selection assembly 408 may include biasing members 134, 136, a seal support 138, and a mode seal 128. The mode seal 128 is shaped to correspond to a seal cavity 350 in the mounting plate 144 and is configured to seal against the top surface of the backplate 146, allowing the user to direct fluid flow from the handle to a specific set or group of nozzles in the shower head 100. For example, the mode seal 128 may be a sealing material such as rubber or other elastomers and may include a mode selection orifice 410 defined therethrough. In this way, the mode seal 128 may be aligned with a specific mode orifice to fluidly connect the handle 102 to the engine 126 and to the specific mode orifice within the engine 126, while sealing other mode orifices into the engine 126. In some embodiments, the mode selection orifice 410 may be configured to substantially match the construction of mode orifices 284, 286, 288, 290, and may therefore include a plurality of support ribs 412 spanning the width of the orifice 410. However, rib 412 may be omitted in other embodiments. The pattern seal 128 may also include first and second spring posts 414, 416 extending upward from its top surface.

[0101] The seal support 138 provides additional rigidity and structure to the mode selection assembly 408, particularly the mode seal 128. The seal support 138 can be, for example, a rigid material such as plastic, metal, etc. The structure provided by the seal support 138 helps the seal 128 maintain a sealing relationship with the backplate 146 under water pressure. In some embodiments, the seal support 138 may substantially match the construction of the mode seal 128 and may include orifices for the spring posts 414, 416 and the mode selection orifice 410. Although the seal support 138 is shown as a component separate from the mode seal 128, in other embodiments, the seal support 138 may be integrally constructed with the mode seal 128.

[0102] Shower head assembly

[0103] refer to Figure 2 and Figure 4 The assembly of the shower head 100 will now be discussed in more detail. As will be discussed in more detail below, the engine 126 is assembled at a higher level and then connected to the shower head 104. To assemble the engine 126, the massage mode assembly 152 is assembled, and then the baffles, namely the front plate 148, the inner plate 146, and the back plate 146, are connected to the nozzle rings 154 and mist rings 156 connected to the respective plates. In particular, refer to Figure 11The pin 168 of the massage mode assembly 152 is received into a corresponding orifice in the anchor post 360 of the spray plate 164. Then, the pin-shaped protrusion 374 of the turbine 166 slides around the pin 168. The turbine 166 is oriented such that the cam 372 is located on the opposite side of the turbine 166 facing the spray plate 164. With the turbine 166 and the spray plate 164 connected via the pin 168, the opener / closer 170 is connected to the turbine 166. Specifically, the cam 372 of the turbine is positioned within the cam orifice 384 of the opener / closer 170.

[0104] Once the massage mode component 152 has been constructed, it is connected to the panel 148 and received within the massage chamber 220. (See reference) Figure 2 , Figure 4 , Figure 6B and Figure 11 Pin 168 is positioned within pin recess 224 on shelf 228 of panel 148. Opener 170 is oriented such that restraint edges 388, 390 are parallel to corner walls 222 of panel 148. Curved walls 392, 394 of opener 170 are aligned with curved walls of massage chamber 220. Figure 4 As shown, the turbine 166 is received within the massage chamber 220 so as to be located below the top edge of the annular wall 236 of the massage chamber 220, and the bottom edge of the jet plate 164 rests on the top of the annular wall 236. The annular wall 236 supports the jet plate 164 and prevents the jet plate 164 from frictionally engaging with the top of the turbine 166, thereby helping to ensure that there is a gap between the turbine 166 and the jet plate 164 to allow the turbine 166 to rotate without experiencing frictional losses due to engagement with the jet plate 164. The gap between the turbine 166 and the jet plate 164 (determined by the height of the annular wall 236) can be changed as desired.

[0105] exist Figure 4 In the illustrated embodiment, turbine inlets 354, 356, and 358 are located on the top surface of the spray plate 164, such that inlets 354, 356, and 358 do not interfere with the movement of the turbine 166. However, in other embodiments, inlets 354, 356, and 358 may be positioned on the bottom surface of the spray plate 164, and the turbine 166 may be spaced apart from the spray plate 164 by a certain distance. Figure 4 The greater distance shown allows for further clearance between the top of turbine 166 and turbine injector inlets 354, 356, 358. It should be noted that the injection plate 164 can be press-fitted onto the sidewall of the third annular wall 234, thus securing the injection plate 164 in place, and the injection plate 164 also helps to secure the pin 168 in place within the pin recess 224. This configuration secures the massage mode assembly 152 to the panel 148 while still allowing the turbine 166 to rotate within the massage chamber 220.

[0106] refer to Figure 4 , Figure 6B and Figure 14 Once the massage mode component 152 is positioned within the massage chamber 220, the mist plug ring 156 is attached to the panel 148. In one embodiment, mist plugs 398 are received in corresponding nozzle chambers 226, with the bottom end of each mist plug 398 protruding above the shelf surrounding the nozzle outlet 396. (See above regarding...) Figure 14 As discussed, the fog plug 398 is configured such that water can flow around the fog plug 398 and into the chamber 226, and flow out through the fog outlet 396, as will be discussed in more detail below.

[0107] In some embodiments, the fog plugs 398 may be interconnected via webbing loops 420. In these embodiments, the fog plugs 398 may be easier to handle and assemble than if they were separate, non-interconnected plugs. For example, a user assembling the shower head 100 may pick up the loop 420, which may be easier to handle than the individual plugs 398, and then press each plug 398 into its corresponding chamber 226. The webbing forming the interconnection between the fog plugs 398 in the loop 420 may also rest on the upper edge of each chamber 226. The length of the fog plug 398 below the webbing of the loop 420 may not exceed the depth of the chamber 226. Thus, the bottom of the fog plug 398 is spaced apart from the shelf 228 in each chamber 226.

[0108] After the fog ring 156 is attached to the panel 148, the inner panel 158 can be attached to the panel 148. (Reference) Figure 4 , Figures 6B to 7B The inner plate 158 is coaxially aligned with the front panel 148, and the massage opening 252 is located above the massage chamber 220 to allow fluid communication with the massage chamber 220, even though the inner plate 158 is located above the front panel 148.

[0109] The front surface 238 of the inner plate 158 is aligned to face the back surface 194 of the panel 148. The outer wall 242 of the inner plate 158 sits atop the first annular wall 230 of the panel 148, and the first annular wall 244 of the inner plate 158 sits atop the second annular wall 232 of the panel 148. The engagement of the outer wall 242 and the first annular wall 244 of the inner plate 158 with the first annular wall 230 and the second annular wall 232 of the panel 148, respectively, defines a second fluid channel 398 (see [link to documentation]). Figure 4 In other words, the joint between the walls of panel 148 and inner panel 158 fluidly connects the first flow path 248 of inner panel 158 and the second flow path 214 of panel 148, thereby defining the fluid channel 398 within the shower head 100.

[0110] Similarly, the first annular wall 244 and the second annular wall 246 of the inner plate 158 engage with the second annular wall 232 and the third annular wall 234 of the panel 148 to define a third fluid channel 400 formed by the second flow path 250 of the inner plate and the third flow path 216 of the panel 148.

[0111] Two finger-like bodies 260 and 262 of the inner plate 158 extend above the massage chamber 220 and the massage mode assembly 152. However, due to the separation walls 264, 266, and 268, fluid can be selectively distributed to one or more fluid channels, either individually or in combination with each other, as discussed in more detail below.

[0112] refer to Figure 4 , Figures 6A to 8B Once the inner panel 158 is aligned with and connected to the panel 148, the back panel 146 is connected to both the inner panel 158 and the panel 148. Specifically, the peripheral wall 296 of the back panel 146 is aligned with the peripheral wall 206 of the panel 148 to engage with each other. In this way, the back panel 146 can be configured such that the back side 276 will be positioned above the flow of the front side 278 of the back panel 146.

[0113] The first annular wall 298 of the back plate 146 engages the top surface of the outer wall 242 of the inner plate 158. Thus, the combination of the back plate 146, the inner plate 158, and the front plate 148 defines a first fluid passage 396 (see [link]). Figure 4 Additionally, the second annular wall 300 of the back panel 146 engages with the first annular wall 244 of the inner panel 158 to define the upper second pattern channel 404 (see...). Figure 4 As will be discussed in more detail below, the first orifice 254 of the first flow path 248 of the inner plate 158 fluidly connects the upper second mode channel 404 to the second mode channel 398 defined by the front panel 148 and the inner plate 158.

[0114] Continue to refer to Figure 4 , Figures 6A to 8B The third annular wall 302 of the back plate 146 engages with the second annular wall 246 of the inner plate 158, such that the engagement of the first and second annular walls 244, 246 of the inner plate 158 with the second and third annular walls 300, 302 of the back plate 146 respectively defines the upper third mode channel 406. The upper third mode channel 406 is connected to the third mode channel 400 via the second collection fluid of the orifice 256 of the inner plate 158, which will be discussed in more detail below.

[0115] The second annular wall 246 of the inner plate 158 and the third annular wall 302 of the back plate 146 define the fourth mode channel 402 (see Figure 4 The fourth mode channel 402 is fluidly connected to the massage mode component 152.

[0116] The separating walls 264, 266, and 268 of the inner panel 158 engage with the corresponding separating walls 304, 306, and 308 of the back panel 146 to define various distribution channels for each mode of the shower head. For example, the separating wall 268 of the inner panel 158 engages with the separating wall 306 of the back panel 146, the separating wall 264 of the inner panel 158 engages with the separating wall 304 of the back panel 146, and the separating wall 266 of the inner panel 158 engages with the separating wall 308 of the back panel 146.

[0117] Due to the connection between the inner panel 158 and the back panel 146, the first mode orifice 284 is fluidly connected to the fourth mode channel 404, the second mode orifice 286 is fluidly connected to the first mode channel 396, the third mode orifice 288 is fluidly connected to the fourth mode channel 402, and the fourth mode orifice 290 is fluidly connected to the upper third mode channel 406. In this example, the first mode orifice 284 corresponds to the mist mode, the second mode orifice 286 corresponds to the full-body mode, the third mode orifice 288 corresponds to the massage mode, and the fourth mode orifice corresponds to the focused spray mode. However, the above mode examples are merely illustrative, and the types of modes and the correspondence between specific mode orifices can be changed as needed.

[0118] Panel 148, inner panel 158, and back panel 146 can be joined together once assembled. For example, panels 146, 148, and 158 can be fused together, for example, by ultrasonic welding, heating, adhesives, or other techniques that hold the panels together. Once fixed, panel 148, inner panel 158, and back panel 146, together with massage mode assembly 408, form the motor 126 of shower head 100. This allows motor 126 to be connected to shower head 104 as a single component, rather than being attached to each panel individually. Additionally, the connection between each panel can be substantially leak-proof, preventing water flowing through each channel within the panel from leaking into other channels.

[0119] Once the back panel 146 is connected to the inner panel 158, the mounting plate 144 and the mode selection assembly 408 can be connected to the back panel 146. (See reference) Figure 2 , Figure 4 , Figure 8A , Figures 9A to 9B as well as Figure 15 The first and second biasing members 134 and 136 are received around the first and second spring posts 346 and 348 of the mounting plate 144, respectively. The biasing members 134 and 136 are then received through corresponding biasing orifices in the seal support 138. When the biasing members 134 and 136 are received around the spring posts 414 and 416 of the pattern seal 128, the pattern seal 128 is then connected to the biasing members 134 and 136. The pattern seal 128 is then positioned within the seal cavity 350 of the mounting plate 144.

[0120] In embodiments where the shower head 100 includes a feedback feature, a spring 140 is received around a portion of a plunger 142, and the plunger and spring are received in a brake pin cavity 342 of a mounting plate 144. The spring 140 is configured to bias the plunger 142 against the back side 276 of a backplate 146.

[0121] After the mode selection component 408, plunger 142, and spring 140 are connected to the mounting plate 144, the mounting plate 144 is connected to the shower head 104. An O-ring 150 is received around the outer surface of the engagement wall 338 of the mounting plate 144. Fasteners 132a, 132b, 132c, and 132d are then received through fastening orifices 334 in the mounting plate 144 and secured to corresponding fastening posts (not shown) extending from the surface within the shower head 104 and / or handle 102. Fasteners 132a, 132b, 132c, and 132d secure the mounting plate 144 to the shower head 100.

[0122] Once the mounting plate 144 is connected to the spray head 104, the engine 126 can be connected to the mounting plate 144. Specifically, the rounded edge 330 of the mounting plate 144 is received within the locking band 282, and the fingers 318 are bent to allow the rounded edge 330 to be positioned within the locking band 282, then snap-fitted around the edge of the rounded edge 330. A lip 320 on each finger 318 extends over a portion of the rounded edge 330 (see...). Figure 4 The motor 126 is fixed together as a single component, allowing for quick attachment and detachment from the shower head 104 via a snap-fit ​​connection with the mounting plate 144. It should be noted that the fingers 318 allow the motor 126 to rotate relative to the mounting plate 144, enabling the user to selectively change the mode of the shower head 100. However, the lip 320 prevents the motor 126 from detaching from the mounting plate 144, even under water pressure.

[0123] refer to Figure 2 , Figure 4 and Figure 5 ,

[0124] Once the engine 126 is attached to the mounting plate 144, the nozzle ring 154 is received into the cover plate 150, and individual rubber nozzles are inserted into the corresponding nozzle orifices 178. In some embodiments, only certain patterns may include rubber nozzles, and in these embodiments, the nozzle ring 154 may correspond to a specific pattern. However, in other embodiments, each pattern may have a rubber nozzle and / or may be associated with a nozzle ring. In embodiments where the nozzle is formed by the rubber nozzle ring 154, the nozzle can be cleaned more easily. For example, during use, the nozzle may become clogged by deposits or calcification from elements in the water supply. For rubber nozzles, the nozzle can be deformed or bent to break down the deposits and flush them out of the nozzle, while for non-flexible nozzles, the nozzle may have to be soaked in a chemical cleaning solution or cleaned through another time-consuming process.

[0125] refer to Figure 2 and Figures 4 to 6B The cover plate 150 can be secured to the engine 126. Specifically, a panel 148 is positioned within the cover plate chamber 172, wherein corresponding nozzle assemblies are aligned with corresponding nozzle orifices in the cover plate 150. An alignment bracket 174 is connected to the panel 148 when locking tabs 208, 210 are received through bracket orifices 176 in the cover plate 150. The locking tabs 208, 210 connect the engine 126 to the cover plate 150 such that when the cover plate 150 rotates, the engine 126 rotates accordingly. For example, when the user rotates the mode selector 118, the alignment bracket 174 engages the tabs 208, 210, causing the engine 126 to move together with the cover plate 150.

[0126] refer to Figure 2 and Figure 3 The regulator 160 and filter 162 can be received at the threaded end 106 of the handle 102 and secured to the handle 102. Once the cover 150 is secured to the engine 126 (and thus to the shower head 104), and the filter 162 and regulator 160 (if included) are connected, the shower head 100 is ready to be connected to a water source, such as a J-tube or other fluid source, and is ready to be used.

[0127] Shower head operation

[0128] The operation of the shower head 100 will now be discussed in more detail. (Reference) Figures 2 to 4Water enters the shower head 100 through inlet 108 in handle 102, or, in the case of a fixed or wall-mounted shower head, water directly reaches the spray head 104 through the inlet. As water enters, it flows through inlet conduit 172 to the spray head chamber 175. The spray head chamber 175 is fluidly connected to the engine inlet 336 in mounting plate 144. Fluid flows through the engine inlet 336 and through the mode selection orifice 410 of mode seal 128, which is aligned with the engine inlet 336. The fluid path of the water after passing through the mode selection orifice 410 depends on the alignment of the engine 126 (specifically the back plate 146) with the mode selection assembly 408.

[0129] For example, during a first mode (such as a full-body spray mode), the mode seal 128 can be aligned such that the mode selection orifice 410 is positioned directly above the second mode orifice 286 of the back panel 146. Fluid flows through the mode selection orifice 410, through the second mode orifice 286, and into the first mode channel 396. The sealing material of the mode seal 128 prevents fluid from flowing into other mode channel orifices. Starting from the first mode channel 396, fluid flows out through the outlet 200 in the panel 148 and into the rubber nozzle of the nozzle ring 154, and then out through the cover plate 150.

[0130] During a second mode (such as a fog mode), the engine 126 rotates via the mode selector 118 to a position where the mode seal 128 is aligned with the first mode orifice 284. In this example, the mode selection orifice 410 of the mode seal 128 is directly aligned with the first mode orifice 284 to fluidly connect the spray head chamber 175 to the upper second mode channel 404. As water flows into the upper second mode channel 404, it flows through the first orifice 254 in the inner plate 158 into the second mode channel 398. From the second mode channel 398, fluid flows around the fog plug 418 into the nozzle chamber 226. The shape of the fog plug 418 causes the water to rotate before leaving the fog outlet 422. This rotation of the water results in fog spray characteristics, where the water is in a fine mist with reduced droplet size.

[0131] During the third mode (such as focused spray), the engine 126 rotates, aligning the mode selection orifice 410 of the mode seal 128 with the fourth mode orifice 290. In this example, fluid flows from the shower head chamber 175 through the fourth mode orifice 290 into the upper third mode channel 406. Fluid then flows into the third mode channel 400 through the second orifice 256 in the inner panel 158. Once in the third mode channel 400, the fluid exits the shower head through the second set of nozzles 114 on the panel 148.

[0132] During the fourth mode (such as massage mode), the engine 126 rotates to align the mode selection orifice 410 of the mode seal 128 with the third mode orifice 288 of the backplate 146. Fluid flows from the spray head chamber 175 into the fourth mode channel 402. Once in the fourth mode channel 402, the fluid impacts the spray plate 164. (Reference) Figure 4 , Figure 10 and Figure 11 When water impacts the jet plate 164, water enters the inlet orifice 366 and optionally the pressure orifice 362. As water flows through the inlet orifice 366, it impacts the blades 368 of the turbine 166. As water impacts the blades 368 of the turbine 166, the turbine 166 rotates around a pin 168 fixed to the panel 148.

[0133] Figure 16A This is an enlarged cross-sectional view showing the shower head 100 with the switch 170 in the first position. Figure 16B This is an enlarged cross-sectional view showing the shower head with the on / off switch 170 in the second position. (Reference) Figure 4 , Figures 10 to 12 and Figures 16A to 16B As the turbine 166 rotates, the cam 372 moves accordingly. With the rotation of the cam 372, the cam 372 abuts against the inner sidewall 386 of the opener / closer 170 and moves the opener / closer 170. Due to the eccentricity of the cam 372, the opener / closer 170 moves about the central axis of the turbine 166. However, when the corner wall 222 engages the constraint edge 388 of the opener / closer 170, the movement of the opener / closer 170 is constrained by the corner wall 222. Therefore, as the cam 372 rotates, the opener / closer 170 moves substantially linearly across the massage chamber 220 in a reciprocating manner. In particular, the corner wall 222 restricts the movement of the opener / closer 170 to a substantially linear path.

[0134] For example, such as Figure 16A As shown, when cam 372 rotates in the R direction, the opener 170 moves across the massage chamber 220 in a linear motion M direction. In this position, fluid flows from the jet plate 164 through the open space between each turbine blade 368, through the opener 170, and into the first nozzle row 120. Due to the substantially linear motion of the opener 170, each massage outlet 198 in the first row 120 opens substantially simultaneously. Water flows out of the panel 148 substantially simultaneously through the first row 120.

[0135] refer to Figure 16BAs the turbine 166 continues to rotate, the cam 372 continues to move in the R direction, causing the on / off switch 170 (due to the corner wall 222) to move substantially in the linear motion direction M, but toward the opposite side wall of the massage chamber 220. When the on / off switch 170 moves to the second position, each nozzle of the first row 120 is essentially simultaneously covered and each nozzle of the second row 122 is essentially simultaneously exposed or opened. This causes the water flow through each outlet 198 in the specific nozzle rows 120, 122 to start and stop simultaneously, producing a "hammering" or more powerful effect. That is, unlike the gradual opening and closing of outlets 198 in specific nozzle rows 120, 122 in a conventional massage mode shower head, the nozzle rows 120, 122 operate in a binary manner, wherein each row 120, 122 is either "on" or "off", and in the "on" state, each outlet is open, and in the "off" state, each outlet is closed.

[0136] The intermittent opening and closing of the outlets in each of the nozzle rows 120, 122 creates a massaging spray characteristic. Specifically, water flows out of the first row 120 and then the second row 122, producing a powerful, hammering effect when the water hits the user. The instantaneous start and stop of the water flow creates a more intense massage effect. This dual effect allows the massage force to feel even stronger, which allows the shower head 100 to use a reduced water flow rate while still producing a massage experience that replicates that of a shower head with an increased water flow rate.

[0137] As briefly described above, the user can selectively change the mode of the shower head 100 by rotating the mode selector 118. (Reference) Figure 4 When the user rotates the mode selector 118, the cover plate 150 engages the tab 208 on the panel 148 and causes the engine 126 to rotate together. As the engine 126 rotates within the spray head 104, the back plate 146 rotates relative to the mode seal 128 and the plunger 142.

[0138] As the back panel 146 rotates, the user's force overcomes the spring force exerted by the spring 140 on the plunger 142 and biasing members 134, 136, causing the back panel 146 to move. As the user rotates the mode selector 118, the plunger 142 compresses the spring 140 and disengages from the first braking recess 292. When the back panel 146 has been fully rotated to reach the second braking recess 292, the spring 140 biases the plunger 142 into the braking recess 292. This allows the user to receive feedback tactilely and optionally via a click or mechanical engagement sound, letting the user know that he or she has activated another mode. In one embodiment, as will be discussed below, the mode seal 128 may be positioned across two mode orifices 284, 286, 288, 290, thereby allowing simultaneous activation of two modes of the shower head 100. In this embodiment, the back panel 146 may include braking recesses 292 for each individual mode and each combined mode, i.e., there may be seven braking recesses for four discrete modes. However, in other embodiments, the combination mode may not have an associated brake and / or may have fewer or more brakes and modes for the shower head.

[0139] Additionally, when the back panel 146 rotates due to the user's rotation of the mode selector 118, the mode seals 128 are positioned along the back panel 146 in their respective locations. The mode seals 128 can be directly aligned with one or more of the mode orifices 284, 286, 288, 290 to activate a single mode. Alternatively, the mode seals 128 can be positioned such that the mode selection orifice 410 is fluidly connected to two of the mode orifices 284, 286, 288, 290. For example, the mode seals 128 can be positioned between two orifices such that a portion of each orifice is sealed while a portion is open. In this configuration, water can flow through both mode orifices 284, 286, 288, 290 simultaneously, activating two modes of the shower head 100 at the same time. The combination mode may be limited to a mode with mode openings 284, 286, 288, 290 positioned adjacent to each other, or in other embodiments, the seal 128 may be changed or the shower head may include two or more mode seals, which may allow the shower head 100 to activate two or more modes that do not have mode openings adjacent to each other.

[0140] In embodiments where the backplate 146 includes a stop protrusion 294 received in a stop cavity 344 of the mounting plate 144, the stop protrusion 294 can rotate within the stop cavity 344 when the user rotates the engine 126. The stop cavity 344 can be configured to provide a “hard stop” to the user, limiting the range of rotation that the mode selector 118 can take. In particular, the rotation can be determined by the arc length of the stop cavity 344. As the engine 126 is rotated by the mode selector 118, the stop protrusion 294 travels within the cavity 344 until it reaches the end of the cavity 344. Once the stop protrusion 294 reaches the end of the cavity 344, engagement of the stop protrusion 294 with the cavity wall prevents the user from rotating the mode selector 118 further. The hard stop helps prevent damage to the shower head 100 because the user cannot over-rotate the mode selector 118 beyond the desired position.

[0141] Additional Examples

[0142] In some cases, increased force intensity and pulse length may be desired, for example, to enhance the user experience and / or to increase force to compensate for reduced water flow rate. In these cases, the massage mode component can be modified to alter the pulse time and waveform, producing stronger and more abrupt water pulses. In these cases, the massage mode component is configured to allow the on / off switch to "dwell" or remain in a first and second position for a period of time, increasing the length of the water pulses through one or more nozzles associated with the first and second positions. In one example, the cam can be configured to have a discontinuous or non-circular outer surface that includes one or more corners and / or distinctive edge surfaces. For example, the cam may include a trefoil configuration defining a leading edge, a dwelling edge, and a following edge, wherein one or more edges may be separated by distinctive corners or vertices, such as a first or leading corner and a second or following corner. The distinct edges cause the on / off switch to begin moving, dwell in one position, and then transition, wherein the transition time may be less than the dwell time in the first and second positions, which increases the pulse time of the set of nozzles in fluid communication with the inlet during the first or second position.

[0143] Figures 17A to 17C Various views of the massage mode component 500 are shown. It should be noted that any features not specifically discussed may be related to those described above with respect to Figures 1 to 12. Figure 16B The features shown and discussed are the same or similar. Furthermore, it should be understood that the massage mode component 500 can be integrated into the shower head 100, such as by positioning it within the motor.

[0144] The massage mode component 500 may include a massage chamber 502, which may be defined as a separate compartment or as part of the panel 148. The massage chamber 502... Figures 17A to 17CThe massage chamber 502 is shown as a separate component, but in many cases, it can be formed as a third annular wall 234 in the panel 148. The massage chamber 502 can be defined as an outer wall 526, which can be the same as the third annular wall 234 and in fluid communication with the water inlet, and is configured to receive other components of the massage mode assembly 500.

[0145] Two or more nozzle rows 504, 506 may be defined on the bottom surface of the massage chamber 502, each nozzle row including one or more nozzles. For example, the first nozzle row 504 may include nozzles 522a, 522b, 522c, 522d, and the nozzle row 506 may include nozzles 524a, 524b, 524c, 524d. Nozzle rows 504, 506 may be the same as or substantially the same as nozzle rows 120, 122. It should be noted that although nozzle rows 504, 506 are shown as arcuate or crescent-shaped, in other configurations, nozzle rows 504, 506 may be constructed differently, such as including aligned nozzles, such as to form adjacent parallel straight rows of nozzles.

[0146] The small piece 520 can be defined on the bottom surface of the massage chamber 502 and can be similar to the small piece 196. For example, the small piece 520 can be defined as a recess in the bottom wall of the massage chamber 502 and can be positioned between the two nozzle rows 504, 506.

[0147] refer to Figure 17C The massage chamber 502 may include walls defining a track, which may include two corner walls 530, 532 and two end walls 528a, 528b. In one embodiment, the end walls 528a, 528b may be slightly curved, such as convex bends, and may correspond to the shape of the nozzle rows 504, 506. However, in other embodiments, the end walls 528a, 528b may have different shapes, such as parallel straight walls. The corner walls 530, 532 may be parallel to each other and extend between the end walls 528a, 528b. Similar to corner wall 222, the corner walls 530, 532 may serve to restrict or limit the movement of the opener / closer, as will be discussed in more detail below. The corner walls 530, 532 may be integrally formed with respect to the shape of the massage chamber 502 (e.g., the entire chamber may be formed to have the shape of the corner walls 530, 530), or may be separate extensions, such as edges projecting from the inner wall of the massage chamber 502.

[0148] The massage mode assembly 500 may also include a jet plate 508 defining one or more inlets 510a, 510b, 510c. The jet plate 508 may be substantially similar to the jet plate 164 and includes one or more inlet jets 510a, 510b, 510c, which may be similar to inlet jets 354, 356, 358 in fluid communication with a water source (such as an engine inlet). A small piece 509 may be defined as an extension on the top surface of the jet plate 508 and define a recessed cavity on the inner surface of the jet plate 508.

[0149] A pin 516, substantially similar to pin 168, may be included in the massage mode assembly 500. Pin 516 may define the rotation axis of the turbine and be configured to be fixed in the massage chamber 502 and the jet plate 508, as discussed in more detail below.

[0150] refer to Figure 17B and Figure 17C The opener / closer 518 can form part of the massage mode assembly 500. The opener / closer 518 can be somewhat similar to the opener / closer 170 or boot described above. However, the opener / closer 518 can have a cam orifice 540 of a different shape. For example, the cam orifice 540 can be configured to increase the dwell time of the opener / closer 518 and can have a generally rectangular shape. In a specific embodiment, the cam orifice 540 can be defined by an inner wall 542, which can have multiple lengths, such as two end edges or walls 544, 546 parallel to each other and two side edges or walls 548, 550 parallel to each other and perpendicular to the end edges 544, 546. In this way, there can be four walls, for example, a first edge 544, a second edge 548, a third edge 546, and a fourth edge 550. In some embodiments, end edges 544, 546 extend across the width of the opener 518, side edges 548, 550 extend along the length of the opener 518, and in some cases, the length of end edges 544, 546 may be longer than the length of side edges 548, 550.

[0151] The turbine 512 can be used to drive the opener 518 inside the massage chamber 502. Figure 19A and Figure 19B Various views of turbine 512 are shown. (Reference) Figure 19A and Figure 19BThe turbine 512 may include a plurality of blades 566 that receive water impact forces to rotate the turbine 512. The blades 566 extend radially outward from a central hub 562 that may define the center of the turbine 512. As the blades 566 extend from the outer surface of the central hub 562, they may be spaced apart from each other. In some embodiments, the distal ends of the blades 566 may be coupled to a turbine outer wall 564. For example, as... Figure 19A As shown, the turbine outer wall 564 may define the outer periphery of the turbine 512 and extend between the blades 566. In other embodiments, the blades 566 may have free distal ends (see, for example...). Figure 22 ).

[0152] The pin orifice 562 may be defined to pass through the center of the center hub 562 and may be aligned with the central axis of the turbine 512. The pin orifice 562 may extend through the entire center hub 562 and be configured to receive a pin 516 passing through it.

[0153] Cam 560 extends from the bottom or a second side of turbine 512. Cam 560 may be integrally defined with turbine 512 or may be a separate component coupled thereto, but in either embodiment, cam 560 is configured to rotate as turbine 512 moves. Cam 560 may extend from central hub 562. In some embodiments, cam 560 is configured to increase the dwell time of opener 518 compared to other embodiments and may have a discontinuous or non-circular outer surface. For example, cam 560 may include two or more distinct edges around its outer surface.

[0154] In one embodiment, the cam 560 may include a leading edge 568, which may be defined as an outwardly curved surface originating at a bottom transition point 578 on the center hub 562 and terminating at a first or leading corner 574 or a apex. A dwelling edge 570 may extend from the leading corner 574 and is also convexly curved, extending at an angle relative to the leading edge 568, such as between 30 and 160 degrees, and optionally 120 degrees. The dwelling edge 570 may terminate at a second or following corner 576 or a apex, and a following edge 572 may extend from the following corner 576 at an angle relative to the dwelling edge 570. For example, the dwelling edge 570 and the following edge 572 may be oriented at an angle between 30 and 160 degrees relative to each other, and optionally at 120 degrees. The following edge 572 can extend from the following corner 576 to the transition point 578, which can be defined as a point on the outer surface of the center hub 562. In these cases, the cam 560 can be defined with... Figure 12The cam 372 in the middle has a trilobed or trilobal surface with different unique surfaces. The orientation and curvature of the different blades (e.g., leading edge 568, dwelling edge 570, and following edge 572) can be varied depending on the desired transition and torque application. For example, the curvature of the leading edge 568 can be configured to produce a smooth transition when the opener 518 transitions from a substantially stationary position (e.g., a first position or a second position) to movement, such as moving towards the opposite position.

[0155] In one embodiment, the corner-to-corner angle of the dwell edge 574 can be approximately 90 degrees, defined from the leading corner 574 to the following corner 576. This corner-to-corner angle can correspond to the rotation angle of the cam 560 that holds the switch 518 in a fixed position, as discussed in more detail below. Where a longer dwell time may be desired, the angular extension of the dwell edge 570 (e.g., the corner-to-corner angle) can be increased. In these cases, the movement of the switch 518 may be more abrupt, which may enhance the pulse of the shower head output, but may require increased torque applied by the turbine 512.

[0156] In some embodiments, the leading edge 568, the dwelling edge 570, and the following edge 572 may have substantially the same perimeter and curvature and may be defined as a Reuleaux triangle, except that the bottom or third point may be rounded and defined as a tangent point on the center hub 562 rather than an extending corner. In these embodiments, the cam 560 may have a constant width such that all points on a particular side edge are equidistant from the opposite vertices or corners 572, 576. As a specific example, a point along the leading edge 568 may be equidistant from the following corner 576, and a point along the following edge 572 may be equidistant from the leading corner 574.

[0157] refer to Figure 17B and Figure 17C Massage mode components 500 can be assembled such that the opener / closer 518 is coupled to the cam 560. For example, the cam 560 can be received within a cam orifice 540, and a portion of the inner wall 542 of the opener / closer 518 can engage with the outer surface of the cam 560. The turbine 512, cam 560, and opener / closer 518 can then be positioned within a massage chamber 502, wherein the opener / closer 518 is aligned such that its longitudinal edges extend parallel to the corner walls 530, 532 of the massage chamber 502. In this manner, the two side edges 548, 550 of the cam orifice 540 can be parallel to the corner walls 530, 532, and the end edges 544, 546 can extend in substantially the same direction as the end walls 528a, 528b.

[0158] Pin 516 can be inserted into pin hole 562 of turbine 512, and the first end of pin 516 is received in a small block 520 on the bottom surface massage chamber 502. Spray plate 508 can be attached to the top of massage chamber 502, and the second end of pin 516 can be received in a corresponding small block 509 on spray plate 508. Small blocks 509 and 520 are used to secure pin 516 in place so that turbine 512 can rotate about pin 516, for example, pin 516 defines the axis of rotation of turbine 512 and cam 560.

[0159] Massage mode assembly 500 can operate in a similar manner to massage mode assembly 152, but can produce more distinctive and / or more powerful water pulses. Specifically, as water enters the massage chamber 502 through the jet plate 508 and specifically through the jet inlets 510a, 510b, 510c (such as from the spray head chamber 175), the water impacts the blades 566 on the turbine 512. The impact causes the turbine 512 to rotate about the pin 516. As the turbine 512 rotates, the cam 560 engages the opener / closer 518 and causes the opener / closer 518 to move in a substantially linear manner from a first position to a second position within the massage chamber 502, wherein in the first position, the opener / closer 518 blocks the second nozzle row 506 and opens the first nozzle row 504, and in the second position, the body of the opener / closer 518 blocks the first nozzle row 504 and opens or exposes the second nozzle row 506. Due to the discontinuous outer surface of cam 560, the opener / closer 518 can be used to pause in each of the first and second positions before transitioning to another surface. For example, for a rotation of at least 10 degrees of the cam and up to 180 degrees of the cam 560, the opener / closer 518 can be substantially held in either the first or second position (sufficient to block the corresponding nozzle rows 504, 506). Depending on the tolerances of the massage mode assembly, when in the first position, the opener / closer 518 may have some minimal movement within chamber 502, but this movement may be insufficient to allow water to reach the covered nozzles. In many cases, the opener / closer 518 can be configured to remain in either the first or second position and not move until the transition to the next position begins.

[0160] In some cases, the angular extension of the dwelling edge 570, such as the distance between the leading corner 574 and the following corner 576, can partially define the time period for which the opener / closer 518 is held in the first or second position, respectively. For example, in a particular embodiment, the dwelling edge 570 may define a 90-degree corner to a corner span, and in this example, the opener / closer 518 may remain fixed or locked in the first or second position for approximately 90 degrees. The opener / closer 518 may remain in the first or second position for an additional time, for example, sufficient to block flow toward the corresponding nozzle rows 504, 506, but may begin to move slightly (e.g., begin to transition) an additional 20 degrees. As a specific example, the opener / closer 518 may be configured to hold the corresponding nozzle rows 504, 506 blocked for more than 10 degrees and, in one option, 110 degrees of rotation. This can be compared to a circular cam in other embodiments, where a circular cam can hold the opener / closer in the blocked position for 10 degrees or less of rotation.

[0161] Figures 20A to 20F The diagram illustrates various positions of the cam 560 and the opener / closer 518 as the opener / closer 518 moves within the massage chamber 502. (Reference) Figure 20A In the first position, the opener / closer 518 is positioned above the second nozzle row 506, disconnecting nozzles 524a, 524b, 524c, and 524d from the fluid inlet and opening or fluidly connecting the first nozzle row 504 and its nozzles 522a, 522b, 522c, and 522d to the fluid inlet. In this position, fluid flows out of the massage chamber 502 through the nozzles 522a, 522b, 522c, and 522d of the first nozzle row 504. As the turbine continues to rotate, the leading edge 568 of the cam 560 rotates to engage the end wall 544 of the inner wall 542 of the opener / closer 518. This engagement initiates movement of the opener / closer 518, moving it from the first position.

[0162] refer to Figure 20B After engaging with the leading edge 568 of the cam 560, the leading bevel 574 rotates to engage the end wall 544 of the opener / closer 518. The leading bevel 574 pushes the opener / closer 518 into a second position. It should be noted that in some cases, the cam 560 and cam orifice 540 of the opener / closer 518 can be configured such that the cam 560, during its rotation, does not strike or engage the side edges 548, 550 of the opener / closer 518, but only engages the end edge of the inner wall 542, which can help hold the opener / closer 518 in the desired position.

[0163] refer to Figure 20CIn the second position, the opener / closer 518 covers the first nozzle row 504, separating nozzles 522a, 522b, 522c, and 522d from the fluid inlet, and exposes or opens the second nozzle row 506, fluidly connecting nozzles 524a, 524b, 524c, and 524d to the fluid inlet. In this position, as the cam 560 continues to rotate, the opener / closer 518 is fixed in this position, causing the dwelling edge 570 to brush against the end wall 544 of the opener / closer 518, applying a retaining force to the opener / closer 518 to prevent it from rotating out of the second position. Figure 20D As shown, as the cam 560 continues to rotate, the opener / closer 518 remains in the second position, while the dwelling edge 570 continues to be oriented toward the end wall 544. It should be noted that in some embodiments, the dwelling edge 570 may engage the end wall 544, and in other embodiments, such as based on tolerances or to allow ease or movement, the dwelling edge 570 may not directly engage the opener / closer 518, but may prevent the opener / closer 518 from moving laterally toward the first position (e.g., acting as a stop to prevent movement in the opposite direction).

[0164] refer to Figure 20E After the dwelling edge 570 rotates past the end wall 544 and toward the side edge 548, the opener / closer 518 can move freely from the second position (e.g., release), and the cam 560 is positioned such that the leading edge 568 abuts against the opposing end wall or edge 546, thereby initiating the movement of the opener / closer 518 back to the first position. Then, as... Figure 20F As shown, the leading corner 574 can complete the movement of the opener 518 to the first position, and the dwelling edge 570 can be used again to hold the opener 518 in place for a period of time corresponding to the perimeter length of the dwelling edge 570.

[0165] The dwell or pause times of the on / off switch 518 in the first and second positions allow the first nozzle row 504 and the second nozzle row 506 to remain open or closed for longer periods than the massage mode assembly 152. This additional time, which may correspond to the peripheral length of the dwell edge 570, generates a more powerful water pulse through the nozzles of the open nozzle rows 504, 506, resulting in a more distinctive pulse. In particular, at the same flow rate as the massage mode assembly 152, the massage mode assembly 500 can generate increased force because fewer nozzles may be open at any given time; for example, both nozzle rows 504, 506 may only be open together for a rapid transition time, but otherwise only one is open or closed, and the on / off switch 518 remains in the closed or open position at a greater degree along the rotational path of the turbine 512 compared to the massage mode assembly 152. In some embodiments, massage mode assembly 152 can generate a sine wave of the opener / closer position as the opener / closer moves within the massage chamber, while massage mode assembly 500 can generate a more square waveform of the opener / closer position because the opener / closer pauses at the top or bottom of each wave, rather than transitioning rapidly like a sine wave. Additionally, because the transition time between the first and second positions in massage mode assembly 500 is faster, the transition time (e.g., the sloping edges of the waveform) in massage mode assembly 500 may be steeper compared to massage mode assembly 152.

[0166] In some embodiments, the massage mode component may be configured to receive water in different orientations. Figures 21 to 23 Another example of a massage mode assembly 600 is shown. This example may be substantially the same as the massage mode assembly 500, but may include a tangentially oriented water inlet leading into the massage chamber 602. For example, see reference... Figure 21 and Figure 22 The massage mode assembly 600 may include a jet cover 608 having one or more inlets 610a, 610b, 610c, 610d oriented on the outer sidewall of the jet cover 608, rather than on the top surface of the jet plate 508 as shown. In the jet cover 608, the inlets 610a, 610b, 610c, 610d may be defined around the outer circumference or periphery of the jet cover 608 and are configured to tangentially direct water to the turbine 612. In some embodiments, the jet cover 608 may include additional inlets, such as four inlets 610a, 610b, 610c, 610d, which may contribute to a more constant flow rate to the massage chamber 602 compared to an odd number of inlets (e.g., three inlets in the jet cover 608).

[0167] Additionally, in this example, the turbine 612 may include free blades 666. For example, as Figure 22 and 23 As shown, blades 666 can radiate outward from the central hub 662, similar to turbine 512. The outer wall 564 can be omitted, allowing blades 666 to have free distal ends. Optionally, as... Figure 23 As shown, in this example, cam 660 may include a hollow center portion, which can facilitate manufacturing (e.g., ease of molding) and allow for a lighter turbine 612. For example, cam 660 may include the same outer surfaces, such as leading edge 668, dwelling edge 670, and following edge 672, as well as leading corner 674, following corner 676, and transition point 678, but the internal mass of cam 660 may be hollow or partially recessed.

[0168] Similarly, the massage chamber 602 may be configured to be partially defined by the walls of the spray cover 608 and may include a base plate including corner walls 630, 632 and nozzle rows 604, 606, but otherwise the internal volume of the chamber 602 may be defined by other flow plates of the shower head 100 engine and / or the spray cover 608.

[0169] In operation, massage mode component 600 can be substantially similar to massage mode component 500, and as per [the relevant information]... Figures 20A to 20F As described, the action of the opener 518 is more pronounced between the first and second positions, but water from the inlet can be tangentially angled at the turbine 612 via inlets 610a, 610b, 610c, 610d.
