During assembly of the illustrated embodiment of the wand 20 of FIGS. 3a-1-6b, the boost actuator module 36 is assembled. Exemplary assembly steps will be described. The boost toggle button 206 is inserted into the boost toggle opening 44 in the shell 24 until the boost pins 48 of the shell 24 are received in the boost saddles 214 of the boost toggle button 206. The boost toggle spring 208 is inserted into the upstream end of the shell 24 until the downstream end of the boost toggle spring 208 is received in the boost toggle cavity 212 of the boost toggle button 206.

During assembly of the illustrated embodiment of the wand 20 of FIGS. 3a-1-6b, the already assembled mode module 30 and boost module 28 and the already assembled shell 24 and boost actuator module 36 are further assembled. Exemplary assembly steps will be described.

During assembly of the illustrated embodiment of the wand 20 of FIGS. 3a-1-6b, the face module 34 is assembled. Exemplary assembly steps will be described. The aerator 190 is inserted into the wand opening 200 in the spray face 192. The upstream end of the spray face 192 is inserted into the downstream end of the shell 24 until the threads 204 on the spray face 192 mate with the threads 54 in the shell 24.

During assembly of the illustrated embodiment of the wand 20 of FIGS. 3a-1-6b, the mode actuator module 38 is assembled. Exemplary assembly steps will be described. The mode toggle button 216 is inserted into the mode toggle opening 46 in the shell 24 until the mode pins 222 of the mode toggle button 216 are received in the mode saddles 50 of the shell 24 and the mode toggle teeth 224 are interleaved with the mode selector teeth 154. In the illustrated embodiment, if the first side 218 of the mode toggle button 216 is depressed, there is a starting stream flow, and the inlet disk flow openings 158 are aligned with the outlet disk stream outlet passages 164a. In the illustrated embodiment, if the second side 220 of the mode toggle button 216 is depressed, there is a starting spray flow, and the inlet disk flow openings 158 are aligned with the outlet disk spray outlet passages 164b.

During assembly of the illustrated embodiment of the wand 20 of FIGS. 3a-1-6b, other flow components are assembled. Exemplary assembly steps will be described. The check valve 230 and the screen 228 are inserted into the adapter opening 72. The wand hose 22 is connected to the inlet region 70 of the adapter 60 until threads on the wand hose 22 mate with the threads 86 on the adapter 60.

During operation of the illustrated embodiment of the wand 20 of FIGS. 3a-1-6b, water flows from the wand hose 22 into the wand 20. Depending on whether boost is selected, water will continue through and exit the wand 20 as a normal flow or a boost flow. Additionally, depending on which mode is selected, water will continue through and exit the wand 20 as a stream or a spray. As a result, water exiting the wand 20 can be a normal flow stream, a normal flow spray, a boost flow stream, or a boost flow spray. However, one of ordinary skill in the art will appreciate that more or less flows and/or modes could be provided. Similarly, one of ordinary skill in the art will appreciate that different flows and/or modes could be provided. As an example, a third flow could be a low flow. As another example, a third mode could include both stream and spray, be a different stream, or be a different spray. As another example, both modes could be different streams or both modes could be different sprays.

When water is not flowing to the wand 20 (see FIG. 5a), the boost toggle projection 210 of the boost toggle button 206 is spaced from the downstream end of the generally cylindrical portion 88 of the slide 62. With normal flow (see FIG. 5b), as water starts to flow to the wand 20, water pressure causes the slide 62 to compress the boost spring 64 and move in a downstream direction until the downstream end of the generally cylindrical portion 88 of the slide 62 abuts the boost toggle projection 210 of the boost toggle button 206. In this position, as water exits the adapter flow passage 80 (including the adapter flow openings 78), water enters the slide flow passage 100 slightly upstream of the nose portion 90 of the slide 62. The constrained space in the slide flow passage 100 restricts water flow.

The boost is selected by pressing on the upstream end of the boost toggle button 206 (see FIG. 5c). As the upstream end of the boost toggle button 206 is pressed, the downstream end of the boost toggle button 206 is raised causing the boost toggle projection 210 of the boost toggle button 206 to be raised. With boost flow, increased water pressure causes the slide 62 to further compress the boost spring 64 and further move in the downstream direction. In this position, as water exits the adapter flow passage 80 (including the adapter flow openings 78), water enters the slide flow passage 100 further upstream of the nose portion 90 of the slide 62. The less constrained space in the slide flow passage 100 increases water flow.

In the normal flow (see FIG. 5b) of the illustrated embodiment of the wand 20 of FIGS. 3a-1-6b, water flows through the boost module 28 components of the wand 20 in the following order: (1) the screen 228, (2) the check valve 230, (3) the adapter flow passage 80 (including the adapter flow openings 78), and (4) a more restricted portion of the slide flow passage 100 (including the slide flow openings 98).

In the boost flow (see FIG. 5c) of the illustrated embodiment of the wand 20 of FIGS. 3a-1-6b, water flows through the boost module 28 components of the wand 20 in the following order: (1) the screen 228, (2) the check valve 230, (3) the adapter flow passage 80 (including the adapter flow openings 78), and (4) a less restricted portion of the slide flow passage 100 (including the slide flow openings 98).

When water stops flowing to the wand 20, the boost spring 64 causes the slide 62 to move in an upstream direction and return to the position shown in FIG. 5a. Additionally, the boost toggle spring 208 causes the boost toggle button 206 to toggle and return to the position shown in FIG. 5a.

The mode is selected by pressing on the first side 218 or the second side 220 of the mode toggle button 216. As the first side 218 of the mode toggle button 216 is pressed (see FIG. 6a), the interaction of the mode toggle teeth 224 and the mode selector teeth 154 causes the mode selector 118 and the inlet disk 120 to rotate in a counterclockwise direction. In this position, the mode selector flow openings 146 and the inlet disk flow openings 158 align with the outlet disk stream outlet passages 164a, the web seal stream outlet passages 170a, the flow guide stream outlet passages 178a, and the aerator 190 in the wand opening 200 of the wand 20. As the second side 220 of the mode toggle button 216 is pressed (see FIG. 6b), the interaction of the mode toggle teeth 224 and the mode selector teeth 154 causes the mode selector 118 and the inlet disk 120 to rotate in a clockwise direction. In this position, the mode selector flow openings 146 and the inlet disk flow openings 158 align with the outlet disk spray outlet passages 164b, the web seal spray outlet passages 170b, the flow guide spray outlet passages 178b, and the wand nozzles 202.

In the stream mode (see FIG. 6a) of the illustrated embodiment of the wand 20 of FIGS. 3a-1-6b, water flows through the mode module 30 components of the wand 20 in the following order: (1) the mode selector flow passage 148, (2) the mode selector flow openings 146, (3) the inlet disk flow openings 158, (4) the outlet disk stream outlet passages 164a, (5) the web seal stream outlet passages 170a, (6) the flow guide stream outlet passages 178a, and (7) the aerator 190 in the wand opening 200 of the wand 20.

In the spray mode (see FIG. 6b) of the illustrated embodiment of the wand 20 of FIGS. 3a-1-6b, water flows through the mode module 30 components of the wand 20 in the following order: (1) the mode selector flow passage 148, (2) the mode selector flow openings 146, (3) the inlet disk flow openings 158, (4) the outlet disk spray outlet passages 164b, (5) the web seal spray outlet passages 170b, (6) the flow guide spray outlet passages 178b, and (7) the wand nozzles 202.

As described above, in the illustrated embodiment, the boost module 28 includes the fixed boost sub-module 56 and the movable boost sub-module 58. Similarly, the mode module 30 includes the fixed mode sub-module 106 and the movable mode sub-module 108. Further, the fixed boost sub-module 56 includes a single component (i.e., the adapter 60), and the movable boost sub-module 58 includes a plurality of components (i.e., the slide 62 and the boost spring 64). Similarly, the fixed mode sub-module 106 includes a plurality of components (i.e., the retainer 110, the outlet disk 112, the web seal 114, and the flow guide 116), and the movable mode sub-module 108 includes a plurality of components (i.e., the mode selector 118 and the inlet disk 120). Additionally, the face module 34 includes a plurality of components (i.e., the aerator 190 and the spray face 192). However, one of ordinary skill in the art will appreciate that each of the fixed boost sub-module 56, the movable boost sub-module 58, the fixed mode sub-module 106, the movable mode sub-module 108, and the face module 34 could include a single component or a plurality of components.

In an exemplary embodiment, the fixed boost sub-module 56 includes an inlet region (e.g., the inlet region 70 of the adapter 60) and a first flow passage (e.g., the adapter flow passage 80). Additionally, the movable boost sub-module 58 includes a second flow passage (e.g., the slide flow passage 100). Further, the movable mode sub-module 108 includes a third flow passage (e.g., the mode selector flow passage 148) and a plurality of flow openings (e.g., the mode selector flow openings 146 and the inlet disk flow openings 158). Moreover, the fixed mode sub-module 106 includes a plurality of first outlet passages (e.g., the outlet disk stream outlet passages 164a, the web seal stream outlet passages 170a, and the flow guide stream outlet passages 178a) and a plurality of second outlet passages (e.g., the outlet disk spray outlet passages 164b, the web seal spray outlet passages 170b, and the flow guide spray outlet passages 178b).

In an exemplary embodiment, the movable boost sub-module 58 (e.g., the slide 62 and the boost spring 64) is operable to move in a generally longitudinal direction (i.e., along or generally parallel to a central longitudinal axis of the shell 24); and the movable mode sub-module 108 (e.g., the mode selector 118 and the inlet disk 120) is operable to move in a generally circumferential direction (i.e., around a circumference of the shell 24).

In an exemplary embodiment, the first flow passage (e.g., the adapter flow passage 80), the second flow passage (e.g., the slide flow passage 100), the third flow passage (e.g., the mode selector flow passage 148), the plurality of flow openings (e.g., the mode selector flow openings 146 and the inlet disk flow openings 158), the plurality of first outlet passages (e.g., the outlet disk stream outlet passages 164a, the web seal stream outlet passages 170a, and the flow guide stream outlet passages 178a), and the plurality of second outlet passages (e.g., the outlet disk spray outlet passages 164b, the web seal spray outlet passages 170b, and the flow guide spray outlet passages 178b) extend in a generally longitudinal direction (i.e., along or generally parallel to the central longitudinal axis of the shell 24); and the flow of water through the first flow passage (e.g., the adapter flow passage 80), the second flow passage (e.g., the slide flow passage 100), the third flow passage (e.g., the mode selector flow passage 148), the plurality of flow openings (e.g., the mode selector flow openings 146 and the inlet disk flow openings 158), the plurality of first outlet passages (e.g., the outlet disk stream outlet passages 164a, the web seal stream outlet passages 170a, and the flow guide stream outlet passages 178a), and the plurality of second outlet passages (e.g., the outlet disk spray outlet passages 164b, the web seal spray outlet passages 170b, and the flow guide spray outlet passages 178b) extends in a generally longitudinal direction (i.e., along or generally parallel to the central longitudinal axis of the shell 24).

In an exemplary embodiment, the movable boost sub-module 58 (e.g., the slide 62) is operable to move away from and toward the fixed boost sub-module 56 (e.g., the adapter 60). As the movable boost sub-module 58 (e.g., the slide 62) moves away from the fixed boost sub-module 56 (e.g., the adapter 60), the flow of water through the second flow passage (e.g., the slide flow passage 100) increases. As the movable boost sub-module 58 (e.g., the slide 62) moves toward the fixed boost sub-module 56 (e.g., the adapter 60), the flow of water through the second flow passage (e.g., the slide flow passage 100) decreases.

In an exemplary embodiment, the boost actuator module 36 (e.g., the boost toggle button 206) is operable to engage the movable boost sub-module 58 (e.g., the slide 62) to limit movement of the movable boost sub-module 58 (e.g., the slide 62) away from the fixed boost sub-module 56 (e.g., the adapter 60). Further, the boost actuator module 36 (e.g., the boost toggle button 206) is operable to disengage the movable boost sub-module 58 (e.g., the slide 62) to enable movement of the movable boost sub-module 58 (e.g., the slide 62) away from the fixed boost sub-module 56 (e.g., the adapter 60).

In an exemplary embodiment, the movable mode sub-module 108 (e.g., the mode selector 118 and the inlet disk 120) is operable to rotate in a counterclockwise direction and a clockwise direction relative to the fixed mode sub-module 106 (e.g., the outlet disk 112, the web seal 114, and the flow guide 116). As the movable mode sub-module 108 (e.g., the mode selector 118 and the inlet disk 120) rotates in a counterclockwise direction relative to the fixed mode sub-module 106 (e.g., the outlet disk 112, the web seal 114, and the flow guide 116), water flows from the plurality of flow openings (e.g., the mode selector flow openings 146 and the inlet disk flow openings 158) to the plurality of first outlet passages (e.g., the outlet disk stream outlet passages 164a, the web seal stream outlet passages 170a, and the flow guide stream outlet passages 178a). As the movable mode sub-module 108 (e.g., the mode selector 118 and the inlet disk 120) rotates in a clockwise direction relative to the fixed mode sub-module 106 (e.g., the outlet disk 112, the web seal 114, and the flow guide 116), water flows from the plurality of flow openings (e.g., the mode selector flow openings 146 and the inlet disk flow openings 158) to the plurality of second outlet passages (e.g., the outlet disk spray outlet passages 164b, the web seal spray outlet passages 170b, and the flow guide spray outlet passages 178b).

In an exemplary embodiment, the mode actuator module 38 (e.g., the mode toggle button 216) is operable to engage the movable mode sub-module 108 (e.g., the mode selector 118) to rotate the movable mode sub-module 108 (e.g., the mode selector 118 and the inlet disk 120) in a counterclockwise direction. Further, the mode actuator module 38 (e.g., the mode toggle button 216) is operable to engage the movable mode sub-module 108 (e.g., the mode selector 118) to rotate the movable mode sub-module 108 (e.g., the mode selector 118 and the inlet disk 120) in a clockwise direction.

In an exemplary embodiment, the face module 34 includes a first outlet (e.g., the aerator 190 and the wand opening 200) and a second outlet (e.g., the wand nozzles 202). In an exemplary embodiment, the first outlet (e.g., the aerator 190 and the wand opening 200) is operable to fluidly communicate with the plurality of first outlet passages (e.g., the outlet disk stream outlet passages 164a, the web seal stream outlet passages 170a, and the flow guide stream outlet passages 178a) and deliver water from the face module 34 in a first form (e.g., the stream). Similarly, the second outlet (e.g., the wand nozzles 202) is operable to fluidly communicate with the plurality of second outlet passages (e.g., the outlet disk spray outlet passages 164b, the web seal spray outlet passages 170b, and the flow guide spray outlet passages 178b) and deliver water from the face module 34 in a second form (e.g., the spray).

In an exemplary embodiment, the wand 20 has a high flow capacity and a compact size. In an exemplary embodiment, the flow capacity of the wand 20 is represented by a flow coefficient, C_v, of the wand 20. The flow coefficient, C_v, is defined as a flow rate, Q, of the wand 20 (in gallons per minute) divided by a square root of a pressure differential, ΔP, between an inlet and an outlet of the wand 20 (in pounds per square inch), where the specific gravity is 1 (for water). In equation form, C_v=Q/(√ΔP). For the illustrated embodiment, with water exiting the wand 20 in the boost flow stream, the flow coefficient, C_v, of the wand 20 is approximately 0.63. In an exemplary embodiment, the size of the wand 20 is represented by a volume, V, of the shell 24. In the illustrated embodiment, the volume, V, is defined as a diameter, d, of the shell 24 (in inches squared) times a length, l, of the shell 24 (in inches). In equation form, V=d*l. For the illustrated embodiment, the volume, V, of the shell 24 is approximately 2.6 inches cubed. In an exemplary embodiment, with water exiting the wand 20 in the boost flow stream, a ratio of the flow coefficient of the wand 20 to the volume of the shell 24 is greater than approximately 0.125 (see FIG. 7). In an exemplary, with water exiting the wand 20 in the boost flow stream, the ratio of the flow coefficient of the wand 20 to the volume of the shell 24 is greater than approximately 0.15. In an exemplary embodiment, with water exiting the wand 20 in the boost flow stream, the ratio of the flow coefficient of the wand 20 to the volume of the shell 24 is greater than approximately 0.175. In an exemplary embodiment, with water exiting the wand 20 in the boost flow stream, the ratio of the flow coefficient of the wand 20 to the volume of the shell 24 is greater than approximately 0.2. In an exemplary embodiment, with water exiting the wand 20 in the boost flow stream, the ratio of the flow coefficient of the wand 20 to the volume of the shell 24 is greater than approximately 0.225. In the illustrated embodiment, with water exiting the wand 20 in the boost flow stream, the ratio of the flow coefficient of the wand 20 to the volume of the shell 24 is approximately 0.24.

While the wand 20 has been shown and described in the illustrated embodiment as including certain components, one of ordinary skill in the art will appreciate that the wand 20 does not need to include each of these components and/or the specifics of each of these components.

For example, the adapter 60, the slide 62, the mode selector 118, and the inlet disk 120 have been shown and described as including a certain number of flow openings and the outlet disk 112, the web seal 114, and the flow guide 116 have been shown and described as including a certain number of outlet passages. However, one of ordinary skill in the art will appreciate that there could be more or less flow openings and/or outlet passages in any of these components. Additionally, the flow openings and the outlet passages have been shown and described as being equally spaced in a circumferential direction around these components. However, one of ordinary skill in the art will appreciate that the flow openings and outlet passages could not be equally spaced in a circumferential direction around any of these components. Further, the first or stream outlet passages and the second or spray outlet passages have been shown and described as alternating in these components. However, one of ordinary skill in the art will appreciate that the first or stream outlet passages and the second or spray outlet passages could not be alternating in any of these components.

Similarly, the shell 24, the boost toggle button 206, the mode toggle button 216, the slide 62, the retainer 110, the mode selector 118, the inlet disk 120, the outlet disk 112, the web seal 114, and the flow guide 116 have been shown and described as including a certain number of pins, saddles, slots, projections, cavities, teeth, rails, fingers, tabs, and/or notches. However, one of ordinary skill in the art will appreciate that there could be more or less pins, saddles, slots, projections, cavities, teeth, rails, fingers, tabs, and/or notches in any of these components. Moreover, there could be other structure that accomplishes the functions of the pins, saddles, slots, projections, cavities, teeth, rails, fingers, tabs, and/or notches in any of these components.

While the wand 20 has been shown and described in the illustrated embodiment with the components attached or engaged in a particular manner, one of ordinary skill in the art will appreciate that the components of the wand 20 do not need to be attached in this particular manner.

While the wand 20 has been shown and described in the illustrated embodiment with the components assembled in a particular order, one of ordinary skill in the art will appreciate that the components of the wand 20 do not need to be assembled in this particular order.

One of ordinary skill in the art will now appreciate that the present invention provides a wand with boost and mode selections having a high flow capacity and a compact size. Although the present invention has been shown and described with reference to a particular embodiment, equivalent alterations and modifications will occur to those skilled in the art upon reading and understanding this specification.
