DETAILED DESCRIPTION

Referring generally to the figures, various dispensing and/or infusion devices (e.g., infusion assemblies, etc.) are shown. The dispensing devices are configured to dispense a liquid ingredient into water flowing through the device. The devices include a housing that is coupled to a waterway upstream of a water dispensing device, such as a showering and/or misting device (e.g., a showerhead, a handshower, etc.) that sprays or otherwise distributes water. In some embodiments, the entire flow stream of water from the waterway passes through the device (e.g., the housing, etc.). In some embodiments, the dispensing devices include an electrically controlled pump that feeds a liquid ingredient into water flowing through the device.

According to at least one embodiment, the system is configured to control the operation of the pump, and fluid connections to the pump, in response to engagement of a refill apparatus (e.g., a container, a capsule, a bag, a reservoir, etc.) with the device housing. For example, in some embodiments, the refill apparatus includes a diverter interface (e.g., a keyed plug, etc.). The dispensing device and diverter interface of the refill apparatus are configured so that, when the diverter interface engages the dispensing device (e.g., the housing, etc.), the diverter interface actuates a diverter (e.g., a diverter actuator, etc.) of the dispensing device from a dispensing position to a refill position. In the refill position, flow is redirected so that the pump draws the ingredient into the housing instead of delivering the ingredient to the water flowing through the device. The diverter returns to the dispensing position after disengaging the diverter interface from the dispensing device so that activation of the pump dispenses the ingredient from the housing into the water flowing through the device. Such an arrangement enables refill operations without requiring multiple pumps and/or separate actuators to control flow direction through the device, thereby reducing system complexity.

In some embodiments, the diverter interface of the refill apparatus includes an engagement portion that is configured to actuate the diverter. The engagement portion may also be configured as a safety and/or protection feature that prevents the use of non-genuine refill containers to refill the dispensing device, which could contain harmful chemicals or ingredients that could injure a user.

The inline dispensing device also includes a user interface that is configured to simplify user interaction with the device. In some embodiments, the user interface includes a single touch point (e.g., only a single actuator or button) along the dispensing device that enables control of the device between multiple (e.g., three, etc.) different operating modes. Such an arrangement simplifies user interaction with the device and can improve the overall aesthetic of the device.

In some embodiments, the inline dispensing device includes a modular housing design that enables removal of different parts of the device for maintenance and/or repair. For example, the dispensing device may include a removable battery pack housing. The battery pack housing may contain a battery used to power the motor, pump, and/or other electrical components of the dispensing device. The battery pack housing may be removed from the dispensing device to enable recharging of the battery pack via a single electrical connection that is also used to couple the battery pack to the device housing. In some embodiments, the electrical connection is external to the device housing and enables charging in-situ (e.g., without removal of the battery pack from the device housing, etc.). The device housing may be a modular housing that includes various partitions and/or bulkheads that separate the device housing into removable sections that enable removal and replacement of different components without removing the inline dispensing device from the waterway.

In some embodiments, the inline dispensing device includes a refillable capsule. The capsule includes an engagement portion that is configured to removably couple the capsule to the device housing. The capsule also includes a locking interface (e.g., a locking ring) that prevents users from tampering with the capsule, such as by removing the capsule from the device housing. The capsule may also include a tether that secures the cover to the capsule and that prevents the cover from becoming completely separated from a capsule housing of the capsule during refilling operations. Such an arrangement is particularly advantageous in hospitality environments (e.g., hotels, etc.) where owners wish to use the device while reducing the risk of theft or loss.

In some implementations, the dispensing device also includes a hydrogenator that provides power to the electric motor or a battery pack onboard the dispensing device, which can reduce the overall power consumption of the dispensing device, and increase battery life.

Referring to FIG. 1, a shower system is shown that includes an inline dispensing device 100, according to an embodiment. The shower system may be located within a shower enclosure, such as a standalone shower stall or a bathtub. The showering system includes an inlet waterway 10, a water dispensing device 12, and the inline dispensing device 100. In other embodiments, the shower system may include additional, fewer, and/or different components.

The inlet waterway 10 may be a pressurized residential or commercial water supply line that is configured to deliver pressurized water to the water dispensing device 12. In some embodiments, the inlet waterway 10 is a fluid conduit that is coupled to a commercial or residential water supply line.

In the embodiment of FIG. 1, the water dispensing device 12 is a showerhead that is fixedly coupled to the inlet waterway 10. In other embodiments, the water dispensing device may be, or may include, a handshower that is movable relative to the inlet waterway 10. The shower system may include more than one fixed showerhead and/or handshower in various embodiments. While embodiments of the inline dispensing device 100 disclosed herein are described with reference to a shower system, it should be understood that the inline dispensing device 100 may be used with any other type of water dispensing device, commercial or residential plumbing fixture including, but not limited to, a steam and/or steam generator, a faucet, a water supply conduit, and/or other water dispensing devices that are configured to spray or otherwise distribute water into an environment.

The inline dispensing device 100 is disposed between the showerhead and the inlet waterway 10. The inline dispensing device 100 includes a device housing 102. The housing includes an inlet 104 that is fluidly coupled to the inlet waterway 10 and an outlet 106 that is fluidly coupled to the showerhead. The inlet 104 and the outlet 106 may include ports having threaded connectors, quick-connect fittings, or the any other suitable fastener to provide a water-tight seal along the flow path between the inlet waterway 10 and the showerhead.

The inline dispensing device 100 may be disposed at any location upstream of the showerhead. For example, in some embodiments, the inline dispensing device 100 is coupled to a supply elbow configured to redirect water from the inlet waterway to the showerhead. In other embodiments, the inline dispensing device 100 may be coupled to a bar valve, a hydrorail for a shower column assembly, or another suitable location upstream of the showerhead.

The inline dispensing device 100 is configured to dispense an ingredient into water passing therethrough at a location upstream of the showerhead (or according to other embodiments, a handshower, or another plumbing fixture or water dispensing device) in order to improve a user's overall bathing experience.

Referring to FIG. 2, the inline dispensing device 100 includes the device housing 102, a pump 108, a motor 110, a battery pack 112, a diverter 113, and a dispensing control system 114. In other embodiments, the inline dispensing device 100 may include additional, fewer, and/or different components. In some embodiments, the inline dispensing device 100 also includes a hydroelectric generator 115.

Referring to FIG. 3, the device housing 102 includes a housing body 116 and a manifold 118 (e.g., a hollow portion, hollow cavity, etc.) disposed therein. The device housing 102 may be a generally cylindrical body having a circular or semi-circular cross-section. In other embodiments, the shape of the housing may be different (e.g., a rectangular prism having a rectangular cross-section normal to a central axis thereof, etc.). The manifold 118 is fluidly coupled to the inlet 104 and the outlet 106 (see also FIG. 1) and is configured to fluidly couple the inlet 104 to the outlet 106. The manifold 118 includes at least one conduit, for example, an inlet conduit 119 extending radially toward a central axis of the housing body 116 from the inlet 104, and an outlet conduit 121 extending parallel to the inlet conduit and toward the outlet 106 at an outer periphery of the housing body 116. In other embodiments, the design of the manifold 118 may be different (e.g., the inlet conduit and the outlet conduit may extend in different directions, may have different lengths, may include more than one individual conduit, etc.). In at least one embodiment, the manifold 118 is configured to fluidly couple the inlet 104 and the outlet 106 to a filter element coupled to the device housing 102, as will be further described.

In the embodiment of FIG. 1, the device housing 102 (e.g., a central axis of the device housing 102, etc.) is oriented substantially perpendicular to a flow direction through the inlet 104 and the outlet 106 (e.g., a flow direction at a location where the inlet 104 and the outlet 106 engage with the device housing 102), and to a flow direction through the inlet waterway 10. In other embodiments, the shape and/or arrangement of the device housing 102 may be different. For example, the device housing 102 may be arranged parallel to the inlet waterway 10, or arranged in another orientation. Among other benefits, the orientation of the device housing 102 relative to the inlet waterway 10, the inlet 104, and the outlet 106 can reduce a distance of conduit/tubing within the device housing 102 that is needed to fluidly couple the device housing 102 to the waterway 10. The orientation of the device housing 102 shown in FIG. 1 can also reduce the overall footprint of the inline dispensing device within the shower enclosure.

In various embodiments, the device housing 102 is a modular housing that includes a plurality of housing sections 120 that are interconnected. In such embodiments, at least one of the housing sections 120 is removably coupled to an adjacent one of the housing sections 120 and can be removed therefrom to facilitate maintenance and/or repair of various components. The device housing 102 may also include at least one bulkhead 122 (e.g., at least one partition wall, etc.) disposed between two housing sections 120. The bulkhead 122 may be sealingly engaged with at least one of the two housing sections 120. The bulkhead 122 is configured to form a substantially watertight seal between the two housing sections 120 to prevent water from leaking between the two housing sections.

Referring still to FIG. 2, a first housing section 124 of the plurality of housing sections 120 contains (e.g., circumscribes, etc.) at least a portion of the manifold 118. Referring to FIG. 3, the first housing section 124 is fluidly coupled to both the inlet 104 and the outlet 106 of the inline dispensing device 100. The device housing 102 further includes an inlet conduit 119 extending between the inlet 104 and into the first housing section 124 (into an interior cavity of the first housing section 124) and an outlet conduit 121 extending between the first housing section 124 and the outlet 106. In the embodiment of FIG. 3, the inlet conduit 119 and the outlet conduit 121 are oriented parallel to one another and extend radially outward from a central axis of the first housing section 124. In some embodiments, the water may flow tangentially from at least one of the inlet conduit 119 and the outlet conduit 121 into/out of the housing body 116.

Referring still to FIG. 3, in some embodiments, the inline dispensing device 100 is also configured to filter water passing into and through the manifold 118 (flowing into and through the first housing section 124). In such embodiments, the inline dispensing device 100 may include a water filter assembly 125 that is coupled to and/or integrated into the device housing 102. For example, the water filter assembly 125 may be fluidly coupled to the inlet conduit 119 at a location upstream of where the ingredient is dispensed into the water (e.g., upstream of and fluidly coupled to the inlet conduit 119 of the manifold 118). In such embodiments, the water filter assembly 125 forms part of the flow stream through the device housing 102 so that all of the water entering the device housing 102 from the inlet waterway 10 passes through the filter assembly 125. In other embodiments, the water filter assembly 125 is disposed at another location along the flow path through the housing body 116.

In some embodiments, the device housing 102 defines or otherwise includes a water filter port 127 that extends away from the housing body 116 and that is configured to fluidly couple a replaceable water filter assembly 125 to the device housing 102. In other embodiments, the water filter assembly 125 may be integrally formed with the device housing 102. For example, the water filter assembly 125 may form at least a portion of another housing section of the device housing 102 in which a water filter is located. The filter housing section may include conduits to direct the flow of water from the manifold 118 through the water filter, or from the water filter to the manifold 118. The filter housing section may be removable from the device housing 102 to facilitate replacement of the water filter assembly 125.

Referring to FIG. 4 and FIG. 5, and inline dispensing device 200 is shown that includes a water filter assembly 225 that is removably coupled to the device housing 202 of the inline dispensing device 200. The inline dispensing device 200 includes a manifold 218 that is configured to direct the flow of water from an inlet waterway, through the device housing 202 and water filter assembly 225, and out from the device housing 202 toward the water dispensing device.

The manifold 218 includes an inlet conduit 219 extending radially into the housing body 216 of the device housing 202 and across a hydroelectric generator 215. The water filter assembly 225 includes a water filter housing 228 (containing a water filter) that is removably coupled to the manifold 218, between an inlet conduit 219 of the manifold 218 and an outlet conduit 221 of the manifold 218. In other embodiments, the location of the water filter housing 228 along the manifold 218 may be different. In at least one embodiment, the water filter housing 228 is at least partially disposed within an inner cavity of the housing body 216 (e.g., in a first housing section of the housing body 216 that also includes the manifold 218). The water filter assembly 225 includes sealing members 230 (e.g., O-rings, gaskets, etc.) that fluidly couple the water filter housing 228 to the manifold 218.

The water filter housing 228 is configured to direct water from the inlet conduit 219, through the water filter, and to return the clean, filtered water to the outlet conduit 221. In such embodiments, the inline dispensing device 200 may be configured to inject the liquid ingredient into the outlet conduit 221 and downstream from the water filter, which can reduce the risk of premature contamination of the water filter assembly 225. In other embodiments, the inline dispensing device 200 is configured to inject the liquid ingredient into passage defined by the outlet of the device housing 202.

In some embodiments, the water filter assembly 225 and/or device housing 202 additionally includes a water filter cap 232 that is coupled to the housing body 216 and that encloses a portion of (e.g., a lower end of) the water filter housing 228. In some embodiments, the water filter cap 232 is sealingly engaged with the housing body 216, which can reduce the risk of water leakage from the housing body 216. In embodiments without a water filter assembly 225, the water filter cap 232 can be replaced with a cap and/or plug that directly fluidly couples the inlet conduit 219 to the outlet conduit 221, thereby allowing for retrofit of an inline dispensing device to include a water filter assembly, while maintaining a pleasing overall aesthetic for the device housing.

Referring again to FIG. 3, in some embodiments, the inline dispensing device includes a hydroelectric generator 115. The hydroelectric generator 115 is electrically coupled to the battery pack 112 (see also FIG. 2) and is configured to provide power to the battery pack 112. The hydroelectric generator 115 is configured to extract energy from water flowing through the device housing 102 (e.g., the manifold 118). In some embodiments, the hydroelectric generator 115 may be disposed within an interior cavity of the first housing section 124 at a location between the inlet conduit 119 and the outlet conduit 121 of the manifold 118. In such embodiments, the hydroelectric generator 115 may be configured to direct water from the inlet conduit 119 to the outlet conduit 121. It should be understood that the location of the hydroelectric generator 115 may be different in various embodiments. For example, the hydroelectric generator 115 may alternatively be positioned within or along the inlet conduit 119 or the outlet conduit 121. In yet other embodiments, the inline dispensing device 100 may include more than one hydroelectric generator 115.

The hydroelectric generator 115 may include, for example, a turbine that is configured to extract mechanical energy from water flowing therethrough. The hydroelectric generator 115 may also include an electrical power generator that is configured to convert the mechanical energy to electricity to power the battery pack 112 (see also FIG. 2). The hydroelectric generator 115, the battery pack 112, and/or another controller onboard the inline dispensing device 100 may include a battery power control circuit, which may include one or more diodes or another AC to DC converter (e.g., an inverter, etc.) to convert alternating current from the hydroelectric generator 115 to direct current for use in charging the battery pack 112.

Referring again to FIG. 2, a second housing section 126 of the plurality of housing sections defines an ingredient reservoir 128 that is configured to receive at least one liquid ingredient and/or dissolvable ingredient tablet therein. The ingredient(s) may include, for example, an aromatic liquid including essential oils or a mixture of essential oils. The aromatic liquid may emit any one of a plurality of different fragrances (e.g., lavender, vanilla, eucalyptus, peppermint, etc.). Alternatively, or in combination, the fluid may include a soap or other cleaning agent, a lotion (e.g., a skin care ingredient), or any other liquid that could be introduced into the flow stream. In yet other embodiments, the ingredient is embedded or otherwise formed into a water dissolvable tablet that can be placed within the ingredient reservoir 128. It should be understood that the device housing 102 may include multiple ingredient reservoirs 128 for storing different ingredients independently from one another, and for independently controlling the release rate of different ingredients, in various embodiments.

The pump 108 is configured to control the flow of the ingredient within the inline dispensing device 100. The pump 108 is disposed within the device housing 102. In some embodiments, the pump 108 is disposed in a third housing section 130 of the plurality of housing sections 120, which may be removably coupled to the first housing section 124 (or another housing section 120) to facilitate replacement and/or repair of the pump 108 without requiring disassembly or replacement of the entire inline dispensing device. In some embodiments, the pump 108 is removably coupled to the third housing section 130 so that the third housing section 130 may be reusable with different pumps 108.

In some embodiments, the pump 108 is a reversible pump that is configured to operate in at least two different modes and/or directions, including a suction mode (e.g., a first mode, etc.) in which the pump 108 operates to draw, pull, or otherwise move fluid toward the pump 108 and/or into the ingredient reservoir 128, and a discharge mode (e.g., a second mode, etc.) in which the pump 108 is configured to push or otherwise move fluid away from the pump 108 and/or out of the ingredient reservoir 128. In other embodiments, refilling operations may be performed without use of the pump (e.g., the liquid ingredient may be manually squeezed or pressed out from a refill apparatus, or under pressure or vacuum resulting from prior pump operation, etc.) In some embodiments, the pump 108 is a peristaltic pump (e.g., a rotary positive displacement pump). In other embodiments, the pump 108 may be a diaphragm pump, a piston pump, or another type of liquid driver.

The motor 110 is configured to power operation of the pump 108. The motor 110 is disposed within the device housing 102, in a separate section of the device housing 102 from the pump 108 (e.g., in the first housing section 124) so that the pump 108 may be removed from the device housing 102 independently from the pump 108. In other embodiments, the motor 110 may be disposed in the same housing section as the pump 108. In some embodiments, the motor 110 is an electric motor (e.g., a direct current motor) that is configured to be powered by the battery pack 112 onboard the inline dispensing device 100.

The battery pack 112 is configured to power the electrical system components (e.g., the motor 110, the dispensing control system 114, etc.) of the inline dispensing device 100. The battery pack 112 is electrically coupled to the motor 110 and the dispensing control system 114. The battery pack 112 may also be coupled to a hydroelectric generator 115 and/or a control circuit associated with the hydroelectric generator 115 to receive electric power from the hydroelectric generator 115.

Referring to FIG. 6, in some embodiments, the battery pack 112 forms part of a battery pack module 123 that is removably coupled to the device housing 102 (see also FIG. 2). In such embodiments, the battery pack module 123 may include a fourth housing section 132 of the device housing 102 that is removably coupled to one of the other housing sections. For example, referring still to FIG. 6, the fourth housing section 132 may form an axial end of the device housing 102 when the battery pack 112 is installed onto the device housing 102. The fourth housing section 132 may define a battery cavity configured to receive the battery pack 112 therein.

In some embodiments, the battery pack module 123 includes a battery bulkhead 134 (e.g., a battery partition wall) disposed between the battery pack 112 and the remainder of the device housing 102. The battery pack module 123 may also include at least one connector 136 coupled to the battery bulkhead 134. The connector 136 is configured to electrically connect the battery pack 112 with a battery pack charger for the battery pack 112. In such implementations, the battery pack module may be removed from the remainder of the device housing 102 to facilitate charging of the battery pack 112. In at least one embodiment, the battery pack module 123 includes electrical terminals that are separate from the connector 136 and that electrically couple the battery pack 112 with onboard components of the inline dispensing device (e.g., the motor 110, the dispensing control system 114, the hydroelectric generator 115, etc.) when the battery pack module 123 is fully installed onto the device housing 102.

Referring again to FIG. 2, the diverter 113 is configured to control the flow of the ingredient through the device housing 102. In at least one embodiment, the diverter 113 is configured to determine an ingredient flow path through the device housing 102 based on whether a refill apparatus is engaged with the inline dispensing device 100. For example, the diverter 113 may be movable between a first position (e.g., a refill position, etc.) at which activation of the pump 108 draws an ingredient into the device housing 102 (into the ingredient reservoir 128 from a refill container) and a second position (e.g., a dispensing position, etc.) at which activation of the pump 108 delivers the ingredient into the manifold 118, such as from the ingredient reservoir 128 to the manifold 118.

In some embodiments, the diverter 113 includes a movable conduit and/or flow channel that rotates, slides, or otherwise moves with respect to the device housing 102 in response to engagement between the fill apparatus and the device housing 102. In another embodiment, the diverter 113 includes at least one valve (e.g., a solenoid valve) that actuates in response to a determination that the refill apparatus is engaged with the device housing 102.

Referring to FIGS. 7-9, a refill apparatus 301 for use with the inline dispensing device 300 is shown, according to at least one embodiment. The inline dispensing device 300 is configured to interact with the refill apparatus 301 to refill or replenish the ingredient after one or more uses. Referring to FIG. 9, a device housing 302 of the inline dispensing device 300 defines or otherwise includes a refill port 304. The refill port 304 is a recessed area that is defined by the device housing 302. In some embodiments, the refill port 304 also includes a diverter actuator 306 for actuating the diverter in response to engagement between the refill apparatus 301 and the refill port 304.

In some embodiments, the diverter actuator 306 includes a diverter lever that is coupled to the diverter. The diverter lever causes movement (e.g., rotation, translation, etc.) of the diverter in response to insertion of at least a portion of the refill apparatus 301 into the refill port 304. In other embodiments the diverter is electrically actuated in response to detection of the refill apparatus 301 at the refill port 304. For example, the inline dispensing device may include an optical sensor, a capacitive sensor, or another type of proximity sensor disposed at the refill port 304 that is configured to transmit a control signal in response to detecting the presence of the refill apparatus 301 at or within the refill port 304.

In other embodiments, the diverter is electrically actuated in response to a determination that a genuine refill apparatus containing a genuine liquid ingredient has been inserted into the refill port 304. For example, the inline dispensing device 300 may include a barcode reader and/or scanner that is positioned at least partially within or proximate to the refill port 304 of the device housing 302. In other embodiments, the barcode reader may be disposed at another location along the device housing 302 and oriented toward the refill port 304 and/or portion of the refill apparatus 301 when the refill apparatus 301 is engaged with the refill port 304. The barcode reader may be configured to interpret a barcode (e.g., a QR code, etc.) that is affixed to or printed on the refill apparatus 301 and to determine whether the barcode corresponds with a genuine barcode in memory that is associated with a genuine refill apparatus. In some embodiments, the barcode reader forms part of the dispensing control system of the inline dispensing device 300. In response to a determination that the refill apparatus 301 is a genuine refill apparatus, the dispensing control system may be configured to actuate at least one valve of the diverter to fluidly couple the pump to both the refill port 304 and the ingredient reservoir.

In at least one embodiment, the refill port 304 includes (e.g., defines, etc.) a keyed portion 307 (e.g., a key-receiving element, etc.) that is configured to receive a keyed interface of the refill apparatus 301 therein and to prevent a non-genuine refill apparatus from fully engaging the refill port 304.

Referring still to FIGS. 7-9, the refill apparatus 301 is engageable with the refill port 304 to refill the ingredient reservoir of the inline dispensing device 300. The refill apparatus 301 includes a refill container 305 and a diverter interface 308. In other embodiments, the refill apparatus 301 includes additional, fewer, and/or different components.

The refill container 305 is configured to hold a quantity of liquid ingredient for use in refilling the inline dispensing device 300. The refill container 305 defines a liquid reservoir 310 that is configured to contain a liquid ingredient therein. The refill container 305 also includes at least one opening 312 that is fluidly coupled to the liquid reservoir 310. In at least one embodiment, the at least one opening 312 is defined by the refill container 305. In some embodiments, the at least one opening 312 defines part of a channel and/or passage that extends away from the liquid reservoir 310. In some embodiments, the refill container 305 may include a bag, a cannister, a packet, a bladder, a capsule, or another type of liquid containing device.

The diverter interface 308 is coupled to the refill container 305 at the at least one opening 312. The diverter interface 308 is configured to fluidly couple the liquid reservoir 310 to the inline dispensing device 300. The diverter interface 308 includes an engagement portion 314 that is engageable with the inline dispensing device 300 (e.g., the refill port 304) to actuate the diverter of the inline dispensing device 300. Referring to FIG. 9, in some embodiments, the engagement portion 314 includes a keyed interface (e.g., a keyed element, etc.) such as a keyed plug (e.g., a bayonet plug, etc.) having features that engage or otherwise interface with the keyed portion 307 of the refill port 304 to prevent the use of a non-genuine refill apparatus with the inline dispensing device 300.

For example, the diverter interface 308 may include a plug body 316 and at least one protrusion 318 extending radially away from the plug body 316. In the embodiment of FIG. 9, the at least one protrusion 318 includes a pair of studs that are disposed on opposing sides of the plug body 316 and that engage with corresponding cutouts and/or slots 309 of the refill port 304. The size, shape, number, and arrangement of the at least one protrusion 318 may differ in various embodiments. In some embodiments, the keyed interface (e.g., the keyed element, the at least one protrusion 318, etc.) is configured to engage with the diverter lever, such as during rotation of the refill apparatus 301 relative to the inline dispensing device 300, to actuate the diverter from a dispensing position to a refill position, and/or so as to change a flow direction of liquid ingredient through the inline dispensing device 300.

In some embodiments, the at least one protrusion 318 is configured to engage with the refill port 304 to interlock the diverter interface 308 to the inline dispensing device 300. For example, the at least one protrusion 318 may form part of a twist-lock mechanism between the refill apparatus 301 and the inline dispensing device 300 (e.g., a diverter assembly, the refill port 304, etc.) that supports and/or sealingly engages the diverter interface 308 to the inline dispensing device 300 (e.g., the device housing 302), and that is configured to actuate the diverter assembly of the inline dispensing device 300 (e.g., to rotate at least one component of the inline dispensing device 300) to change a flow direction of ingredient therethrough.

The plug body 316 defines a plug opening 320 (see FIG. 8). The plug opening 320 fluidly couples the diverter interface 308 to the liquid reservoir 310 so that a liquid ingredient can be dispensed through the diverter interface 308 and into the inline dispensing device 300.

In some embodiments, the diverter interface 308 also includes a plug cover (not shown) that is movable relative to the plug body 316 to selectively fluidly couple the plug opening 320 to the liquid reservoir 310. In some embodiments, the plug cover may be a film that is removable from the plug body 316 or that is configured to be punctured by a pin or needle at the refill port 304 (e.g., a pin and/or puncturing element of the inline dispensing device 300) upon insertion of the plug body 316 into the refill port 304, or after moving (e.g., rotating, etc.) the plug body 316 relative to the inline dispensing device 300 to lock or otherwise secure the plug body 316 to the inline dispensing device 300. In yet other embodiments, the plug cover is a movable cover that is movably coupled to the plug body 316, and that moves relative to the plug body 316 in response to engagement between the plug body 316 and the refill port 304.

Referring to FIGS. 10-11 and FIGS. 12A-12B (see also FIG. 18), an inline dispensing device 400 is shown, according to an embodiment. The inline dispensing device 400 includes a device housing 402, an inlet 404, an outlet 406, a pump 408, a motor 410, a battery pack 412, and a water filter assembly 425.

Referring to FIG. 11, the device housing 402 defines an ingredient reservoir 428 that is configured to receive at least one liquid ingredient and/or dissolvable ingredient tablet therein. The device housing 402 also includes a liquid level display 430 that is configured to indicate a volume of the at least one liquid ingredient within the ingredient reservoir 428. In the embodiment of FIG. 11, the liquid level display 430 includes an elongated aperture 432 (e.g., an elongated opening, etc.) defined by a sidewall of the device housing 402, and a window 434 disposed within the elongated aperture 432. The window 434 may include a piece of glass, plastic, or another transparent or semi-transparent material that enables viewing of the actual liquid level within the ingredient reservoir 428.

Referring to FIG. 13, the device housing 402 defines a first body portion 436 (e.g., a first elongated portion, etc.) and a second body portion 438 (e.g., a second elongated portion, etc.) that is adjacent to the first body portion 436. In the embodiment of FIG. 13, the first body portion 436 is an elongated cylindrical body housing the pump 408, the motor 410, the battery pack 412, and the ingredient reservoir 428 (see also FIG. 18). The second body portion 438 is at least partially disposed between (i) the first body portion 436 and (ii) flow passages defined by the inlet 404 and the outlet 406. In some embodiments, the second body portion 438 is an elongated cylindrical body having a central axis 440 that extends substantially perpendicular to a central axis 442 of the first body portion 436.

The second body portion 438 is sized to receive the water filter assembly 425 therein. In the embodiment of FIG. 13, the water filter assembly 425 is coupled to the device housing 402 at the second body portion 438 and is disposed substantially within the second body portion 438. The water filter assembly 425 includes a water filter housing 427 that is detachably coupled to the device housing 402 via a twist lock mechanism (e.g., a threaded connection, a twist-lock connection, etc.) or another type of removable connection mechanism.

The water filter assembly 425 is configured to remove particulate contaminants from the incoming water stream, improve clarity, and/or improve water taste and/or odor. The water filter assembly 425 includes a water filter housing 427 and a water filter element disposed therein. The water filter element may include a one, or a combination of, a carbon filter element, a paper-based filter media, a synthetic filter media, a ceramic material, a reverse osmosis membrane, an ion exchange resin, zeolite, sand, or another type of water filter element material.

In the embodiment of FIG. 13, the water filter assembly 425 (e.g., the second body portion 438) is fluidly coupled to the inlet 404 and the outlet 406 by a flow manifold 418. An inlet (e.g., a dirty side, etc.) of the water filter assembly 425, at a central position along a first axial end of the water filter housing 427 is fluidly coupled by the flow manifold 418 to the inlet 404. An outlet (e.g., a clean side, etc.) of the water filter assembly 425, along a perimeter region of the first axial end of the water filter housing 427 (e.g., between the inlet and the outer perimeter at the first axial end) is fluidly coupled by the flow manifold 418 to the outlet 406. In other embodiments, the flow arrangement through the water filter assembly 425 may be reversed (e.g., so that the central region of the water filter housing 427 defines the outlet to the water filter assembly 425, etc.). Together, the inlet 404, the flow manifold 118, the water filter assembly 425, and the outlet 406 define a flow passage for incoming water through the inline dispensing device 400.

Referring to FIGS. 15-16, the inline dispensing device 400 also includes a diverter assembly 444 that is configured to selectively couple the ingredient reservoir 428 (see also FIG. 18) to one of a refill apparatus and a passage defined by the outlet 406. In the embodiment of FIG. 15, the diverter assembly 444 includes a diverter housing 446 and a diverter body 448 (e.g., a diverter, a diverter actuator, etc.) disposed substantially within the diverter housing 446. The diverter assembly 444 also includes a diverter housing cap 450 coupled to the diverter housing 446 and enclosing the diverter body 448 within an internal cavity 452 that is defined by the diverter housing 446.

In the embodiment of FIGS. 15-16, the diverter housing 446 is disposed within the device housing 402 and forms at least a portion of the device housing 402 (e.g., a lower wall of the first body portion 426). The diverter housing 446 defines a substantially cylindrical internal cavity 452 that extends axially away from the lower wall of the device housing 402. Such an arrangement provides a convenient access point away from the inlet waterway for engaging the refill apparatus with the device housing 402, and can ensure adequate clearance to manipulate the refill apparatus with respect to the device housing 402 during refill operations. In other embodiments, the location and/or shape of the diverter housing 446 may be different.

The diverter housing 446 also defines at least two outlet openings extending therethrough, including a first outlet opening 445 (e.g., a first outlet port, etc.) (see FIG. 19) that extends from a first side of the internal cavity 452 and a second outlet opening 449 (e.g., a second outlet port, etc.) that extends from a second side of the internal cavity 452 opposite the first side. The outlet openings are configured to fluidly couple the diverter housing 446 to different parts of the inline dispensing device 400 including the pump 408 (see FIG. 18) and the outlet 406, as will be further described.

In at least one embodiment, the diverter housing 446 defines a keyed opening 447 along a lower wall of the diverter housing 446 that matches a profile of a diverter interface element of the refill apparatus (e.g., that has substantially the same cross-sectional shape as the diverter interface normal to a central axis thereof). In the embodiment of FIGS. 15-16, the keyed opening 447 is a circular shaped opening that includes a pair of diametrically opposed slots extending from an outer perimeter of the circular shaped opening. Beneficially, such an arrangement prevents the use of non-genuine refill products with the inline dispensing device 400 and also forms a twist lock interface that enables securing of the refill apparatus to the device housing after the refill apparatus has been fully installed.

The diverter body 448 (e.g., the diverter, the diverter actuator, etc.) is rotatably coupled to the diverter housing 446 and is configured to rotate relative to the diverter housing 446 to selectively fluidly couple the ingredient reservoir 428 with one of the refill apparatus and the outlet 406 of the device housing 402 (e.g., a passage defined by and extending upstream from the outlet 406 but downstream from the water filter assembly 425). The diverter body 448 is disposed within the internal cavity 452 of the diverter housing 446 and has substantially the same shape as the internal cavity 452 (e.g., a substantially cylindrical shape, etc.).

Referring to FIGS. 17A-17C, the diverter body 448 is shown, according to an embodiment. The diverter body 448 includes a substantially cylindrically shaped element having a circular cross-section normal to a central axis 454 thereof. The cylindrical shape of the diverter body 448 facilitates sealing with the diverter housing 446 (see FIGS. 15-16) during rotation of the diverter body 448 relative to the diverter housing 446. As shown in FIG. 15, the diverter body 448 defines a diverter cavity 456 (e.g., a hollow region, an interior cavity, etc.) extending from a first axial end thereof to an intermediate position between opposing axial ends of the diverter body 448. The diverter cavity 456 is sized to receive a diverter interface (e.g., an engagement portion) of the refill apparatus therein. In the embodiment of FIG. 15, the diverter cavity 456 is a substantially cylindrical shape. In other embodiments, the shape of the diverter cavity 456 may be different and/or may include other features (e.g., steps, tapered surfaces, etc.), which can further reduce the risk of non-genuine refill products, and can also facilitate pre-alignment between the refill apparatus and the diverter assembly 444.

Referring again to FIGS. 17A-17C, the diverter body 448 defines a transverse opening 458 extending through a sidewall of the diverter body 448 from an outer perimeter of the diverter body 448 to the diverter cavity 456. The diverter body 448 also defines an elongated channel, shown as diverter passage 460 that is disposed along an outer perimeter of the diverter body 448. The diverter passage 460 is spaced apart from the transverse opening 458 and the diverter cavity 456 and is fluidly separated from the transverse opening 458 and the diverter cavity 456. In the embodiment of FIGS. 17A-17C, the diverter passage 460 is disposed on an opposite side of the diverter body 448 as the transverse opening 458.

The diverter passage 460 extends in a circumferential direction relative to the central axis 454 of the diverter body 448 about a portion of the diverter body 448 that is axially aligned with the transverse opening 458. In the embodiment of FIGS. 17A-17C, the diverter passage 460 extends approximately 180° across the diverter body 448 (e.g., along an outer surface of the diverter body and across an approximately one-half portion of the diverter body 448).

The diverter body 448 also includes a plurality of seal members 462 extending along an outer surface of the diverter body 448. The plurality of seal members 462 are configured to fluidly separate (i) the transverse opening 458 from the diverter passage 460, and (ii) both the transverse opening 458 and the diverter passage 460 from regions of the diverter cavity 456 at opposing axial ends of the diverter body. In the embodiment of FIGS. 17A-17C, the plurality of seal members 462 include elongated radial protrusions (e.g., ribs, etc.) extending away from an outer surface of the diverter body 448. The elongated radial protrusions include a first pair of elongated protrusions 464 that extend in the circumferential direction about the entire outer perimeter of the diverter body 448, a second pair of elongated protrusions 466 that each extend in an axial direction from a first protrusion of the first pair of elongated protrusions 464 to a second protrusion of the first pair of elongated protrusions 464, and a third pair of elongated protrusions 468 that each extend in the axial direction from the first protrusion of the first pair of elongated protrusions 464 to the second protrusion of the first pair of elongated protrusions. In the embodiment of FIGS. 17A-17C, the second pair of elongated protrusions 466 is disposed proximate to a first circumferential end of the diverter passage 460, and the third pair of elongated protrusions 466 is disposed proximate to a second circumferential end of the diverter passage 460. It should be understood that a different number and/or arrangement of seal members 462 may be used in other embodiments.

In at least one embodiment, the diverter body 448 also includes at least one guide element 472 (e.g., a guide protrusion, etc.) that is configured to engage with the diverter housing 446 and/or the diverter housing cap 450 (such as through a slot defined by the diverter housing cap 450) to prevent over-rotation of the diverter body 448 with respect to the diverter housing 446. In some embodiments, the diverter housing 446 and/or the diverter housing cap 450 (see FIG. 15) also includes at least one detent (e.g., a catch, a slot, an opening, etc.) that is configured to engage with the guide element 472 at first and second circumferential positions that correspond with a refill position of the diverter assembly 444 and a dispensing position of the diverter assembly 444, as will be further described.

Referring back to FIG. 15, in some embodiments, the diverter assembly 444 also includes a spring 470 extending from the diverter housing cap 450 to an axial end of the diverter body 448. The spring 470 is configured to maintain axial compression of the diverter body 448 against a lower wall of the diverter housing 446, which can prevent inadvertent movement of the diverter body 448 relative to the diverter housing 446 and provide tactile feedback to a user.

Referring to FIGS. 18-19, the diverter body 448 is repositionable within the diverter housing 446 between (i) a refill position (e.g., a first position, etc.), in which the refill apparatus is fluidly coupled to the ingredient reservoir 428 in isolation from the outlet 406 of the inline dispensing device 400, and a dispensing position (e.g., a second position, etc.), in which the ingredient reservoir 428 is fluidly coupled to the outlet 406 of the inline dispensing device 400 in isolation from the refill apparatus. In the refill position, the diverter body 448 is rotated so that the transverse opening 458 (see FIGS. 15-16 and FIGS. 17A-17C) is rotationally aligned with the first outlet opening 445 and so that the diverter cavity 456 is fluidly coupled to the pump 408 and the ingredient reservoir 428. In such an arrangement, the diverter passage 460 is fluidly isolated from the first outlet opening by the seal members (e.g., by the second pair of seal members and the third pair of seal members described above).

In the dispensing position, the diverter body 448 is rotated so that a first circumferential end of the diverter passage 460 is rotationally aligned with the first outlet opening 445 and so that a second circumferential end of the diverter passage 460 is rotationally aligned with the second outlet opening 449. In such an arrangement, the diverter passage 460 fluidly couples the first outlet opening 445 with the second outlet opening 449, thereby directing the liquid ingredient received from the ingredient reservoir 428 and the pump 408, to the second outlet opening 449. In the dispensing position, the transverse opening 458 is substantially fluidly isolated (e.g., fluidly separated, etc.) from the first outlet opening 445 and the second outlet opening 459 by the seal members.

Referring to FIGS. 19-20, the second outlet opening 449 is fluidly coupled (e.g., by a fluid conduit such as a tube, a pipe, etc.) to a passage of the device housing 402 that is defined by, and extends upstream from, the outlet 406.

Referring to FIG. 21, a method 500 of refilling an inline dispensing device with a liquid ingredient is shown, according to at least one embodiment. The method 500 may be performed using any one of the refill apparatus 301 and the inline dispensing device 300 of FIGS. 7-9, or the refill apparatus and inline dispensing device 400 of FIGS. 10-11. As such, the method 500 will be described with reference to FIGS. 7-9 and/or FIGS. 10-11. In other embodiments, the method 500 may include additional, fewer, and/or different operations.

At operation 502, a diverter (e.g., a diverter actuator, etc.) of an inline dispensing device is actuated in response to engagement between a refill apparatus and a device housing of the inline dispensing device from a discharge position, in which the diverter fluidly couples a an ingredient reservoir of the inline dispensing device to a pump and to the outlet of the inline dispensing device, to a refill position, in which the diverter fluidly couples the ingredient reservoir to the pump and the refill apparatus.

Operation 502 may include inserting a diverter interface of the refill apparatus into a refill port (e.g., a keyed opening) of the inline dispensing device. For example, operation 502 may include aligning a keyed plug or another keyed element of the diverter interface with the refill port so that at least one protrusion of the keyed plug is rotationally aligned with the refill port (and so that the at least one protrusion is aligned with a corresponding cutout and/or slot of the refill port), pressing the keyed plug into the refill port, and twisting or otherwise manipulating the keyed plug relative to the refill port to: (i) couple the keyed plug to the diverter interface at the inlet port; (ii) sealingly engage the diverter interface with the inline dispensing device; and/or (iii) support the refill apparatus in position relative to the inline dispensing device. In some embodiments, operation 502 includes engaging the at least one protrusion with a diverter lever and/or a diverter body to move the diverter actuator from the discharge position to the refill position.

In some embodiments, operation 502 includes rotating a diverter body (e.g., a diverter element, etc.) of the diverter interface that is disposed within the device housing relative to the device housing so as to fluidly couple the refill apparatus (e.g., the liquid reservoir, etc.) with the ingredient reservoir within the inline dispensing device, as described above.

At operation 504, the pump is operated in a suction mode to draw an ingredient into a device housing (e.g., an ingredient reservoir) of the inline dispensing device from the refill apparatus. Operation 504 may include switching the pump from a discharge mode to a suction mode in response to engagement between the refill apparatus and the inline dispensing device. Operation 504 may also include actuating a switch or another type of actuator in response to insertion of the refill apparatus into the refill port, or in response to rotation or another movement of the refill apparatus relative to the refill port. In yet other embodiments, operation 504 includes switching the pump from a discharge mode to a suction mode in response to user input indicative of a request to refill the inline dispensing device.

Operation 504 may include generating a first control signal to the motor in response to actuation of the switch and/or a user input to the inline dispensing device. In other embodiments, operation 504 may include determining the presence of the refill apparatus at the refill port based on data received from a barcode scanner or proximity sensor at the refill port, and generating a control signal in response to the data. In yet other embodiments, operation 504 includes generating a control signal in response to data indicating that the refill apparatus is a genuine refill apparatus containing a genuine liquid ingredient for use with the inline dispensing device.

At operation 506, the diverter actuator is moved from the refill position back to the discharge position in response to removal/rotation of the refill apparatus relative to the diverter housing and/or in response to a determination the that the refill apparatus is disengaged from the inline dispensing device. Operation 506 may include returning the diverter to the discharge position in response to relative rotation between the refill apparatus and the refill port to decouple the refill apparatus from the inline dispensing device. In other embodiments, operation 506 includes moving or otherwise actuating the diverter in response to an electrical signal from at least one sensor that indicates that the refill apparatus has been removed from the refill port. In some embodiments, operation 506 includes moving the diverter body responsive to relative rotation between the refill apparatus and the device housing. Operation 506 may also include switching the pump from a suction mode to a discharge mode after a threshold time delay from initiation of refill operations and/or in response to user input indicative of a request to cease refill operations.

At operation 508, the pump is operated in a discharge mode to discharge liquid ingredient from the ingredient reservoir of the inline dispensing device into a manifold of the inline dispensing device (and into water flowing through the device housing of the inline dispensing device, such as into a passage defined by the outlet of the device housing).

Referring again to FIG. 2, the dispensing control system 114 is configured to control ingredient refill and dispensing operations for the inline dispensing device 100. In some embodiments, the dispensing control system 114 is configured to coordinate operation of the pump 108 with the diverter 113. The dispensing control system 114 is also configured to control a user experience provided by the inline dispensing device 100 in response to user input.

Referring to FIG. 22, a dispensing control system 600 is shown that may be used with any of the inline dispensing devices disclosed herein. The dispensing control system 600 includes a user interface 602, a diverter 604, and a pump 606, a sensor 607, and a controller 608. In other embodiments, the dispensing control system 600 may include additional, fewer, and/or different components.

The user interface 602 is configured as a human-machine interface for the dispensing control system 600, and enables user interaction with the dispensing control system 600. The user interface 602 may include and input-output interface (e.g., an I/O interface) that is configured to receive user inputs. In at least one embodiment, the I/O interface includes only a single actuator, such as a single button or touch input disposed on the device housing. Referring to FIG. 2, for example, the I/O interface may include only a single user input switch or button 138 disposed on an axial end of the device housing 102. Such an arrangement can simplify user interaction with the inline dispensing device 100 by reducing the number of actuators along the device, which can also improve the overall aesthetic of the inline dispensing device 100. The operation of the single point user input arrangement will be described in more detail with reference to FIG. 23.

Referring still to FIG. 2, in various embodiments, the I/O interface also includes a visual indicator to convey information to a user. For example, the visual indicator may include a first light indicator 140 (e.g., a light emitting diode (LED)) on the button 138 and/or a plurality of light indicators that extend along a perimeter of the button 138 (see also FIG. 12B). In the embodiment of FIG. 2, the inline dispensing device 100 also includes a second light indicator 142 (e.g., an LED strip, etc.) disposed on an opposing axial end of the device housing 102, and extending along a perimeter portion of the device housing 102. The location, arrangement, and number of light indicators along the device housing may be different in various embodiments. Among other benefits, the colors and patterns emitted by the I/O interface can inform the user of the current operating mode of the inline dispensing device 100 and can also provide a comforting visual aesthetic that improves the overall user experience.

It should be appreciated that various other types of I/O interfaces may be included with the inline dispensing device 100 in various embodiments. For example, the I/O interface may include a speaker that is configured to provide audible notifications regarding an operating status of the inline dispensing device, and/or to generate sounds such as music to improve user comfort. The dispensing control system 600, as shown in FIG. 11, may be configured to coordinate these sounds and/or light generated by the LEDs or other visual displays with ingredient dispensing operations, as will be further described.

Referring still to FIG. 22, the sensor 607 may include various types of sensors to determine the operating status of the inline dispensing device. For example, the sensor 607 may include a liquid level sensor to determine whether liquid levels within the ingredient reservoir is below a liquid threshold level. The sensor 607 may also include a proximity sensor, and/or a scanner (e.g., an optical barcode scanner or reader, etc.) used to determine the presence of a refill apparatus at the refill port. The sensor 607 may also include a voltage or current sensor to determine an amount of charge for the battery pack and/or an operating condition of various components within the inline dispensing device. It should be understood that the sensor 607 may be one of multiple sensors that are configured to transmit data to the controller 608 and/or the user interface 602 in various embodiments.

The controller 608 is configured to interpret data from and/or control operation of the user interface 602, the diverter 604, the pump 606, and the sensor 607. The controller 608 includes a processing circuit 610 including a processor 612 and memory 614, a refill apparatus detection circuit 616, an experience detection circuit 618, a pump control circuit 620, and a communications interface 622. In other embodiments, the dispensing control system 600 may include additional, fewer, and/or different components.

The controller 608 may be structured as a separate electronic control circuit within the device housing of the inline dispensing device. The processor 612 is communicably coupled to the memory 614, the refill apparatus detection circuit 616, the experience detection circuit 618, the pump control circuit 620, and the communications interface 622 and is configured to coordinate and control operations of each of the circuits and the communications interface 622. The memory 614 is configured to store data and/or computer code for facilitating the various processes described herein. The memory 614 may include a tangible, non-transient volatile memory that is configured to store instructions thereon which, when executed, cause the processor 612 to perform any of the operations described herein.

The refill apparatus detection circuit 616, the experience detection circuit 618, the pump control circuit 620 may be embodied as separate control circuits that are communicably coupled to the processing circuit 610. In other embodiments, the refill apparatus detection circuit 616, the experience detection circuit 618, the pump control circuit 620 may be modules stored in memory 614. In other embodiments, the refill apparatus detection circuit 616, the experience detection circuit 618, the pump control circuit 620 may be separate control circuits that are communicably coupled to the controller 608.

The refill apparatus detection circuit 616 is configured to determine whether a refill apparatus is engaged with the refill port. In some embodiments, the refill apparatus detection circuit 616 is configured to receive sensor data from the one or more sensors (e.g., the sensor 607) and to determine, based on the sensor data, whether the refill apparatus is inserted into and/or coupled to the refill port. In other embodiments, the refill apparatus detection circuit 616 is configured to determine that the refill apparatus is connected to the refill port based on user inputs (e.g., from the user interface 502). The refill apparatus detection circuit 616 may also be configured to determine an operating condition of the diverter 604 and/or the pump 606 that corresponds with the determination of whether the refill apparatus is engaged with the refill port.

The experience detection circuit 618 is configured to determine a user experience based on inputs from the user, and to determine an operating condition of the inline dispensing device that corresponds with the user experience. The user experience may be a curated user experience that corresponds with user inputs, such as dispensing parameters for dispensing the ingredient into the water (e.g., dispensing time, dispensing speed, etc.). In various embodiments, the user experience may also include an operating parameter and/or algorithm for the I/O interface that corresponds with the dispensing parameters, such as a light color, a light duration, a light intensity, a light pattern, etc. The user experience(s) may be stored in memory 614 as a lookup table and/or an algorithm as a function of user inputs.

In some embodiments, the refill apparatus detection circuit 616 and the experience detection circuit 618 are configured to determine operating parameters for the pump based on the user inputs received from only a single actuator or touch point of the user interface 602. The refill apparatus detection circuit 616 and/or the experience detection circuit 618 may be configured to provide these operating parameters to the pump control circuit 620 to control operation of the pump. The pump control circuit 620 may be configured to control operation of pump 606 between a plurality of discharge modes and a suction mode based on signals from the single actuator.

Referring to FIG. 23, a schematic representation of a control method 700 is shown for controlling operation of an inline dispensing device using only a single actuator. At operation 702, an input from the single actuator is received. The input may include any one of a single short selection 704 corresponding to a short (e.g., a rapid, etc.) press and release of the single actuator, a single long selection 706 corresponding to a press and hold of the single actuator for a threshold period, and a double short selection 708 corresponding with rapidly pressing and releasing the single actuator twice within a threshold period. In other embodiments, the input may include other variants of a single actuator input, such as a single short selection followed, within an actuation period, by a single long selection; or any number of selections (e.g., three short selections, three long selections), or any combination of long and short selections.

At operation 710, in response to the single short selection of the single actuator, the controller (e.g., the pump control circuit 620 of FIG. 22) may be configured to activate the pump in a first operating mode. The first operating mode may be a suction mode, or a discharge mode (e.g., a dispensing mode, etc.) of a plurality of discharge modes. For example, in one embodiment, the first operating mode is a first discharge mode of the plurality of discharge modes. In some embodiments, the controller may also be configured to initiate a curated routine of light and/or sound that corresponds with the first discharge mode. In some embodiments, operation 710 may further include pausing the routine or operation of the pump in response to another single short selection of the single actuator during the routine. Operation 710 may include operating the pump in the first discharge mode (or any other operation mode) for a first discharge period (e.g., a first dispensing period, etc.) based on parameters stored in controller memory, and/or based on a fill level of the inline dispensing device.

For example, referring to FIG. 24, an embodiment of an inline dispensing device 800 is shown that includes three light indicators that each extend in a circumferential direction about an outer perimeter of an actuator, shown as a first indicator 802, a second indicator 804, and a third indicator 806. At operation 710, in response to a single short selection of the single actuator, the controller may be configured to activate the pump in a first operating mode corresponding to a first injection rate (e.g., a first injection intensity, a first injection flow rate, etc.).

The controller may also be configured to activate the first indicator 802 to provide a visual indication to a user that the first operating mode has been selected. The user may then wait a first threshold period until the first operating mode is activated by the controller. In some embodiments, operation 710 further includes receiving an additional short selection of the single actuator to activate the pump in a second operating mode corresponding to a second injection rate that is greater than the first injection rate. In such an implementation, the controller may be configured to activate the second indicator 804 responsive to receipt of the second short selection to provide a visual indication to the user that the second operating mode has been selected. In the embodiment of FIG. 24, operation 710 may further include receiving a third short selection of the single actuator to activate the pump in a third mode of operation corresponding to a third injection rate that is greater than both the first injection rate and the second injection rate. More or fewer selections may be made in other embodiments.

In some embodiments, operation 710 also includes providing other functionality responsive to a short selection of the single actuator. For example, operation 710 may include entering a pause mode to pause pump operation (e.g., temporarily deactivating the pump, etc.) responsive to receipt of a short selection of the single actuator after any one of the dispensing modes has been activated. In such embodiments, the controller may be configured to initiate a periodic blinking of the at least one light indicator a different color to notify the user of a state of operation of the inline dispensing device. Operation 710 may further include reactivating the pump responsive to another short selection of the single actuator during the pause mode.

In some embodiments, the indicators of the inline dispensing device 800 are configured to provide a visual indication corresponding to a level of liquid ingredient remaining within the ingredient reservoir, and/or responsive to a level of the liquid ingredient dropping below an ingredient level threshold. For example, the controller may be configured to activate all three light indicators of the inline dispensing device in a color that is different from the color used to identify the pause mode or any of the dispensing modes.

At operation 712, in response to a single long selection of the single actuator, the controller activates the pump in a second operating mode. In at least one embodiment, the second operating mode is a suction mode to refill the ingredient reservoir of the inline dispensing device. Operation 712 may include confirming engagement between a refill apparatus and a refill port of the inline dispensing device. Operation 712 may also include sending a control signal to the pump to reverse a rotational or operating direction of the pump. In some embodiments, operation 712 includes initiating a curated routine of light and/or sound that corresponds with the suction mode (e.g., pulsing a white LED, etc.). Operation 712 may include operating the pump in the suction mode (or any other operating mode) for a refill period based on parameters stored in controller memory and/or a fill level of the inline dispensing device.

The methods used to control the inline dispensing device based on inputs received at the single button actuator may be different in various embodiments. For example, at optional operation 714, in response to a double short selection of the single actuator, the controller may be configured to adapt the pump to operate in one of a plurality of discharge modes based on user inputs. These modes may correspond to different intensity levels (as described above with respect to operation 710), or different dispensing routines. For example, operation 714 may include accessing a lookup table of intensity levels for operation of the inline dispensing device. Operation 714 may include iterating through the intensity levels in response to single short selections of the single actuator, or another actuation sequence of the single actuator. In some embodiments, operation 714 may include determining a discharge flow rate and/or pump speed based on the intensity levels, and in response to a second double short selection of the single actuator. Alternatively, or in combination, operation 714 may include allowing a user to select between different ingredients, or a combination of different ingredients (e.g., a mixture ratio, etc.) to introduce into the water.

Referring again to FIG. 22, the pump control circuit 620 is configured to control operation of the pump 606, the diverter 604, and/or the I/O interface based on information from the refill apparatus detection circuit 616 and/or the experience detection circuit 618. For example, the pump control circuit 620 may be configured to generate a control signal to the pump 606 to control an operating mode (e.g., a suction mode, a discharge mode, etc.) of the pump 606 and/or an operating speed of the pump 606 based on the user experience. The pump control circuit 620 may also be configured to control operation of the diverter 604, such as by switching the diverter 604 between a refill position and a discharge position, and/or to control a mixing ratio of different ingredients, such as by controlling the operation of different valves of the diverter 604.

The communications interface 622 is configured to control data exchange between various components of the dispensing control system 600 and the controller 608. The communications interface 622 may include a wired and/or wireless interface (e.g., by Bluetooth, a local area network (LAN), near field communication, etc.) for conducting communications.

The embodiments of the inline dispensing devices described with reference to FIGS. 1-24 should not be considered limiting. Various modifications are possible without departing from the inventive principles disclosed herein. For example, the arrangement and/or number of housing sections described with reference to FIG. 2 may be different in various embodiments. Additionally, any one of the housing sections may include subsections to separate different components and/or fluids. For example, in some embodiments, the ingredient reservoir of the device housing may include partition walls that defines multiple chambers within the ingredient reservoir. Such an arrangement can enable the use of different ingredients which may be dispensed independently or in combination with one another, depending on user inputs and user experiences stored in controller memory.

In some embodiments, the housing section that defines the ingredient reservoir may be removably coupled to the device housing. For example, the housing section may form a replaceable ingredient capsule. Referring to FIGS. 25 and 26, various embodiments of an inline dispensing device are shown that include a replaceable ingredient capsule. In the embodiment of FIG. 25, the inline dispensing device 900 is coupled to an inlet waterway of a shower. In the embodiment of FIG. 26, the inline dispensing device 1000 is coupled to a shower rail used to support a hand shower. FIG. 27 and FIG. 28 show front views of the inline dispensing devices 900, 1000, respectively.

Referring to FIGS. 29-31, a replaceable ingredient capsule 1100 for use with any of the inline dispensing devices described herein is shown, according to at least one embodiment. The capsule 1100 includes a capsule housing 1102, a cover 1104, a first engagement portion 1106, a second engagement portion 1108, and a cover tether 1110. In various embodiments, the capsule 1100 may include additional, fewer, and/or different components.

The capsule housing 1102 defines a capsule reservoir 1112 that is configured to receive and retain an ingredient (e.g., a liquid ingredient) therein. The ingredient may be any one of the ingredients described herein for infusion into water flowing through the inline dispensing device. The capsule housing 1102 has a cylindrical shape defining a circular or curved cross-section. In other embodiments, the shape of the capsule housing 1102 may be different (e.g., elliptical, rectangular, etc.).

In at least one embodiment, the capsule housing 1102 defines a latch opening 1103 proximate to an open end of the capsule housing 1102. The latch opening 1103 may be configured to receive a tool therein to unlatch and/or unlock a latch of the cover from the latch opening 1103 to enable refilling of the capsule housing 1102 with an ingredient, as will be further described. In some embodiments, the capsule housing 1102 also defines a recessed area 1128 (e.g., a notch, etc.) having a first notch portion 1130 that extends from the open end of the capsule housing 1102. The recessed area 1128 is a region of reduced housing wall thickness that is configured to guide insertion of the latch of the cover therein. In some embodiments, the recessed area 1128 includes a second notch portion 1132 that extends circumferentially from an end of the first notch portion 1130 to define a twist lock interface for the cover 1104. In some embodiments, a height of the second notch portion 1132 is approximately equal to a heigh of a protrusion that extends radially away from the latch on the cover 1104.

The cover 1104 is coupled to the capsule housing 1102 at a first axial end 1114 of the capsule reservoir 1112. The cover 1104 defines a cup-shaped body but may be formed in other shapes in various embodiments. The cover 1104 is threadably coupled to the capsule housing 1102. In other embodiments, the cover 1104 includes another type of capsule-housing interface, such as a twist-lock, or snap-fit connector to couple the cover 1104 to the capsule housing 1102. In some embodiments, the cover 1104 also includes a seal member (e.g., a gasket, an O-ring, etc.) to sealingly engage the cover 1104 with the capsule housing 1102.

In some embodiments, as shown in FIG. 31, the cover 1104 includes a locking feature to prevent tampering and/or to prevent a user from accessing the liquid ingredient. For example, in at least one embodiment, the cover 1104 defines a latch 1105 extending from an open end of the cover 1104. The latch 1105 is configured to clip onto or otherwise engage the latch opening 1103 of the capsule housing 1102 to secure the cover 1104 to the capsule housing 1102 and to prevent a user from inadvertently accessing the liquid ingredient (to prevent tampering and/or damage to the inline dispensing device resulting from the introduction of dirt and/or ingredients that aren't compatible with the inline dispensing device, etc.).

The first engagement portion 1106 is defined by or coupled to the capsule housing 1102 at a second axial end 1116 of the capsule reservoir 1112. The first engagement portion 1106 is configured to removably couple the capsule housing 1102 to a device housing of the inline dispensing device. In some embodiments, the first engagement portion 1106 may include a lower body portion, such as a cylindrical wall 1118 extending axially away from the capsule housing 1102. The cylindrical wall 1118 defines a plurality of grooves 1120 (e.g., slots, channels, etc.) formed therein. In various embodiments, at least one of the plurality of grooves 1120 is a helically shaped groove that extends at an angle upwardly from an axial end of the cylindrical wall 1118. A first portion 1122 of the at least one groove extends in a first axial direction toward the capsule housing 1102. A second portion 1124 of the at least one groove extends from an end of the first portion 1122, in a second axial direction that is opposite from the first axial direction.

In operation, as shown in FIG. 32A, a user aligns the capsule housing 1102 (and the first engagement portion 1106) with a recessed area of the device housing. The user engages a leading edge of the plurality of grooves 1120 with corresponding radial protrusions in the device housing. The user then twists the capsule housing 1102 relative to the device housing, and against a spring-loaded diaphragm, to engage the radial protrusions with the second portion 1124 of the at least one groove. The orientation of the second portion 1124 prevents the capsule from disengaging the device housing after installation.

Referring again to FIGS. 29-3, the second engagement portion 1108 is configured to prevent a user from inadvertently decoupling the capsule 1100 from the inline dispensing device. In various embodiments, the second engagement portion 1108 includes a locking ring 1126 that is configured to engage the device housing to prevent inadvertent separation of the first engagement portion 1106 from the device housing. In some embodiments, the locking ring 1126 is coupled (e.g., threadably) to the capsule housing 1102 adjacent to the first engagement portion 1106. In some embodiments, the locking ring 1126 may be threadably coupled to the capsule housing 1102 and/or the first engagement portion 1106.

In some embodiments, as shown in FIG. 29, the locking ring 1126 is coupled to the capsule 1100 by a threaded region 1111 that extends between the capsule reservoir 1112 and the first engagement portion 1106. The threaded region may be arranged on the capsule 1100 so that when first engagement portion 1106 is fully engaged with the inline dispensing device, the threaded region extends at least partially into a recessed area defined by the inline dispensing device. In some embodiments, as shown in FIG. 29, the threaded region 1111 extends to an upper end (e.g., an upper edge, etc.) of the first engagement portion 1106 (e.g., an upper end/edge of the plurality of grooves 1120).

During operation, as shown in FIGS. 32B-32C, a user rotates or otherwise moves the second engagement portion 1108 (e.g., the locking ring 1126) into engagement with the device housing, which prevents rotation of the capsule 11100 relative to the device housing, and prevents relative axial movement between the capsule 1100 and the device housing. Such an arrangement can also prevent a user from stealing the capsule 1100.

Referring again to FIGS. 29-31, the cover tether 1110 is configured to prevent the cover 1104 from being fully separated (e.g., removed, etc.) from the capsule housing 1102 when refilling the capsule 1100 with the ingredient. Stated differently, the cover tether 1010 is configured to secure the cover 1004 to the capsule housing 1002 during refilling of the capsule reservoir 1012. In some embodiments, the cover tether 1110 is a chain or cable that extends between mount points on the capsule housing 1102 and the cover 1104. In other embodiments, the cover tether 1110 may include another type of flexible cordage. The chain or cable may include looped portions at opposing ends to secure the chain or cable to the capsule housing 1102 and the cover 1104, such as by using screws or another fastener that extends through each of the looped portions. In the embodiment of FIGS. 29-31 the cover tether 1110 and mount points are disposed within the capsule reservoir 1112, which can improve the overall aesthetic of the inline dispensing device.

Referring to FIGS. 33A-33D, a method of refilling a capsule 1100 includes removing the cover 1104 from the capsule housing 1102, such as by engaging an unlocking tool (e.g., a pin, a key, etc.) with the latch opening 1103 of the capsule housing 1102 and pressing radially against the latch 1105 of the cover 1104 to unlatch the cover 1104 from the capsule housing 1102. The method may further include retaining the cover 1104 proximate to the capsule housing 1102 via the cover tether 1110, adding an ingredient to the capsule reservoir 1112, and re-engaging the cover 1104 with the capsule housing 1102. The method may further include placing a product label or another suitable theft detection device across the cover 1104 and the capsule housing 1102.

The inline dispensing device, of which various exemplary embodiments are disclosed herein, provides several advantages over existing devices. The dispensing device includes a modular housing design that enables different device constructions, depending on application requirements, and eliminates the need to disassemble the entire device housing for component repair and/or maintenance. Together, the housing sections define a single unit that can be retrofit into a shower upstream of a water delivery device to enhance the overall user experience. The inline dispensing device includes a pump that is configured to control dispensing operations based on user preferences. The inline dispensing device also includes a diverter than enables use of the use of the same pump for ingredient refilling operations.
