[0001] This application claims priority to U.S. Provisional Patent Application No. 63 / 331,169, filed on April 14, 2022, entitled “BEVERAGE DISPENSING SYSTEM,” the disclosure of which is incorporated herein by reference in its entirety. Background Art

[0002] Conventional beverage dispensing systems are commonly used in a variety of locations, including restaurants, fast food restaurants, convenience stores, movie theaters, and any business that serves beverages. These beverage dispensing systems typically dispense a variety of beverages of different types and flavors, such as flavored carbonated soda, iced tea, water, or even alcoholic beverages. Typically, such devices use a post-mix dispenser that mixes a beverage additive (e.g., flavored syrup) with a base beverage fluid (e.g., water or soda) before dispensing into a beverage container through a dispensing nozzle.

[0003] The desire to continue to improve the performance of beverage dispensers, also known as bar guns, remains a driving force in overcoming the limitations of known bar gun systems. Summary of the invention

[0004] Embodiments provide an improved beverage dispensing system that reduces foaming and improves the flow of fluids flowing through a multi-layer flow track system embedded in a handle of the beverage dispensing system. According to various embodiments, the flow rate of the fluid dispensed at the nozzle of the beverage dispenser is at least 2.5 ounces / second, which is higher than the flow rate of a conventional beverage dispenser. Embodiments provide higher performance in terms of carbonation, foaming and stratification and carry over. For example, the cup carbonation can be greater than or equal to 3.45 volumes of CO2, the foam height can be less than 1 inch, and the stratification (measured by Brix) can be less than 1.0 ° Brix change. Volume can refer to the space that CO2 will occupy at standard temperature (e.g., 32F) and if removed from the beverage at one atmosphere. In other words, it is the amount of CO2 dissolved in the beverage relative to the volume of the beverage.

[0005] An embodiment provides a modular beverage dispenser, the modular beverage dispenser including a handle that encloses a plurality of flow tracks and includes a dispensing surface that includes a handle base fluid outlet. The modular beverage dispenser further includes a flow control module coupled to the top surface of the handle, the flow control module including a plurality of buttons configured to control the flow through one or more of the plurality of flow tracks to form a beverage.

According to various embodiments, a plurality of elongated diffuser flow inserts extend through the bottom surface of the water diffuser so that the outlets of the plurality of elongated diffuser flow inserts are located downstream of the outlet of the water diffuser.

[0007] Embodiments further provide a tube collector configured to be releasably coupled to a manifold. When portions of the tube collector and / or manifold require maintenance, they can be easily separated from one another. The manifold can in turn be coupled to a plurality of fluid sources. Thus, the tube collector can effectively couple a plurality of fluid sources to a beverage dispenser.

[0008] An embodiment provides a tube collector mechanism, the tube collector mechanism comprising a release mechanism; a tube collector having an angular housing formed by a top cover and a bottom cover, the top cover and the bottom cover enclosing the release mechanism; and a lever, the lever comprising a handle disposed above the top cover of the angular housing; and a guide arm extending through an opening on the top cover of the angular housing.

[0030] Embodiments provide a modular beverage dispensing device (e.g., a beverage dispenser) that reduces foaming and improves the flow of fluid through a multi-layer (e.g., 4-layer or 5-layer) flow track system embedded in a handle of the beverage dispenser. According to various embodiments, the flow rate of the fluid dispensed at the nozzle of the beverage dispenser is at least 2.5 ounces per second, which is higher than the flow rate of a conventional beverage dispenser. Embodiments provide higher performance in carbonation, foaming and stratification, and carryover.

[0031] Figure 1A , 1B 1C, 1D and 1E respectively show a perspective view, a top view, a side view, a rear view and a bottom view of an exemplary modular beverage dispenser 100 according to various embodiments. Figures 1A to 1E As shown, the exemplary beverage dispenser 100 includes a handle 102 and a nozzle module 104 coupled to a front end of the handle 102. A plurality of buttons 106 are disposed on a top surface of the handle 102. The plurality of buttons 106 can control the characteristics, ingredients, or type of beverage dispensed by the modular beverage dispenser 100. For example, when a first button of the plurality of buttons 106 is pressed or otherwise activated, the modular beverage dispenser 100 can be caused to dispense water. When a second button of the plurality of buttons 106 is pressed or otherwise activated, the modular beverage dispenser 100 can be caused to dispense carbonated water or soda water.

[0032] Figure 2A and 2B Exploded views of an exemplary modular beverage dispenser 200 viewed from different angles are shown according to various embodiments. The modular beverage dispenser 200 may include a flow control module 250, a nozzle module 260, and a heel cap 218 that are removably coupled together. The modular design of the beverage dispenser 200 (e.g., a modular bar gun) allows for easy maintenance, cleaning, repair, and replacement of various components as needed.

[0033] The flow control module 250 may include a top plate 204, a plurality of buttons 202 coupled to a top surface of the top plate 204, a butterfly plate 206 placed below the top plate 204, a retaining plate 220 (as shown in FIG. 3 ) coupling the butterfly plate 206 to the top plate 204, and a plurality of tube assemblies 210.

[0034] The handle 208 may include a plurality of flow tracks 702 (in Figure 7B , 7D, 8A-8E), these flow tracks are distributed between four or more layers (for example, four layers, five layers) stacked on top of each other in the handle 208. Figure 7B , 7D, 8A-8E describe the flow path in more detail. The handle 208 also includes a dispensing surface 230 (e.g. Figure 2B As shown in FIG. 2 , the dispensing surface 230 includes a handle base fluid outlet 234 and a plurality of handle mixing fluid outlets 232. The handle mixing fluid outlet 232 may be arranged around the handle base fluid outlet 234. The handle mixing fluid outlet 232 and the handle base fluid outlet 234 may be collectively referred to as a handle outlet.

[0035] The nozzle module 260 may include a diffuser assembly 212, a plurality of diffuser flow inserts 216, and a nozzle 214. Figure 4A -6C describes the nozzle module 260 in more detail.

[0036] Figure 3A , 3B , 3C and 3D show exploded views of an exemplary flow control module 250 of a modular beverage dispenser according to various embodiments. As described above, the flow control module 250 may include a top plate 204, a plurality of buttons 202 coupled to a top surface of the top plate 204, a butterfly plate 206 disposed below the top plate 204, a retaining plate 220 coupling the butterfly plate 206 to the top plate 204, and a tube assembly 210. According to various embodiments, the flow control module 250 may be modular and configured to be easily separated from the handle 208.

[0037] The button 202 is configured to control flow through one or more flow tracks 702 to form a beverage dispensed at the nozzle 214 of the modular beverage dispenser 200. Figure 3AAs shown, the button 202 can have an elongated shape extending toward the side of the handle 208 (e.g., the button 202 can surround the top plate 204). The button 202 provides a large surface that can be easily controlled or pressed by the user of the modular beverage dispenser 200. For example, the button 202 can be in the form of a package switch button, which has an elongated ergonomic shape for smooth actuation. According to various embodiments, the button 202 can be snap-mounted on the top plate 204. Therefore, the button 202 can be easily removed from the top plate 204 or replaced on the top plate 204. Two or more buttons 202 can exchange positions to identify the updated arrangement of beverage components. In some embodiments, the flow control module 250 can be snap-mounted on the handle 208. In some embodiments, the flow control module 250 can be connected to the handle 208 via a fastening device. For example, the top plate 204 can be connected to the handle 208 by a single screw to facilitate removal during cleaning, maintenance, repair or replacement.

[0038] A butterfly plate 206 disposed below the top plate 204 can selectively actuate one or more valves for dispensing one or more beverage components. The selection of the valve corresponds to the button 202 that is activated. The butterfly plate 206 can ensure that only the valve corresponding to the pressed button 202 is activated. For example, if the user of the modular beverage dispenser 200 selects the first button on the right, the butterfly plate 206 ensures that the pressure input is transmitted to the corresponding valve and not to any remaining valves. Details of the valves and the actuation of the valves by the butterfly plate can be found in the assignee's prior patent, namely, U.S. Patent No. 4,986,449, entitled "Beverage Dispensing Device" published on January 22, 1991, the disclosure of which is incorporated herein by reference.

[0039] In some embodiments, the flow control module 250 may include one or more balls connected to the underside of the butterfly plate 206, allowing the butterfly plate 206 to pivot based on pressure applied to one or more buttons 202. The buttons 202 may control the flow of a beverage fluid and / or component that is received at the one or more tube assemblies 210, flows through the handle 208 (e.g., through a flow track 702 disposed in the handle 208, as described below in conjunction with Figure 7B , 7D, 8A-8E further discussed in more detail), and is dispensed at the nozzle module 260 of the beverage dispenser 200.

[0040] The bottom retaining plate 220 holds the butterfly plate 206 and the top plate 204 together. A fastening device 225 (e.g., a single screw) can couple the bottom retaining plate 220 to the top plate 204 when passed through an opening in the butterfly plate 206. The butterfly plate 206 is held between the top plate 204 and the retaining plate 220. For example, when the button 202 or the washer 265 (described below) connected to the tube assembly 210 requires maintenance, the retaining plate 220 can be easily removed (e.g., by removing the single screw 225) and the components can be easily accessed for maintenance and replacement.

[0041] like Figure 3D As shown, the flow control module 250 can also include a substrate fluid button 222, which can control the flow of the substrate fluid, for example, through a larger opening valve. In some embodiments, the substrate fluid button 222 can have a shape, color, texture different from the remaining buttons 202, so that the substrate fluid can be easily distinguished from the reminder mixed fluid. For example, the substrate fluid button 222 can be used to control the water flow. According to various embodiments, the user may wish to distribute water or other substrate fluids at a flow rate greater than the mixed fluid (e.g., additives). When pressed, the substrate fluid button 222 can release the fluid flow (e.g., water flow) through the handle substrate fluid outlet 234.

[0042] A plurality of tube assemblies 210 can be connected to a fluid source or a beverage component source (e.g., substrate fluid or mixed fluid) separately. Each tube assembly is configured to transport beverage components to corresponding handle outlets by a handle. In certain embodiments, the beverage distributed at the nozzle of modular beverage dispenser 200 can be formed by mixing two or more beverage components (e.g., substrate fluid and one or more mixed fluids) conveyed by two or more tube assemblies 210. A plurality of flow tracks 702 can extend between one end of a plurality of tube assemblies 210 and a handle outlet (comprising a handle substrate fluid outlet 234 and a handle mixed fluid outlet 232). Each tube assembly 210 can be connected to corresponding flow track 702 via a mechanical gasket (e.g., O-ring) 265, to prevent leakage and provide improved cooperation between the inlet of flow track 702 and the outlet (e.g., opening) of the tube assembly 210.

[0043] The heel cover 218 may be a split heel cover having a top plate and a bottom plate that enclose at least a portion of the plurality of tube assemblies 210. The heel cover 218 may be coupled to a rear end of the handle 208. According to various embodiments, the heel cover 218 may include a top cover 432, a bottom cover 430, and a fastening device 434 that couples the top cover 432 and the bottom cover 430 to hold the tube assemblies 210 in place, held between the top cover 432 and the bottom cover 430. In some embodiments, the bottom cover 430 may be formed as a single unit (e.g., integral) with the handle 208.

[0044] Figure 4A and 4B An exploded view of a nozzle module 260 and other components of an exemplary modular beverage dispenser are shown according to various embodiments.

[0045] As described above, the nozzle module 260 may include the nozzle 214 mounted around / above the diffuser assembly 212. Figure 4A As shown, the diffuser assembly 212 can be a two-piece diffuser assembly that includes (1) a diffuser base 410 that can be permanently attached to the handle 208 (e.g., attached to the dispensing surface 230 of the handle 208), and (2) a water diffuser 400. In some embodiments, the water diffuser 400 can be removed from the diffuser assembly 212. Alternatively, the water diffuser 400 can be permanently attached to the diffuser base 410 and / or the handle 208. In either configuration, the water diffuser 400 can be placed into an opening in the handle 208 (e.g., the handle base fluid outlet 234) and can be held in place with a gasket (e.g., an O-ring). Figure 5 The water diffuser 400 is described in more detail.

[0046] The nozzle 214 may be configured to be coupled to the diffuser base 410. For example, the nozzle 214 may be a screw-on or slide-on nozzle. The nozzle 214 may include a larger diameter portion 470 and a smaller diameter portion 474 connected to each other via a tapered portion 472. The larger diameter portion 470 may be coupled to the diffuser base 410. The interior of the nozzle 214 may be a hollow cavity configured to receive the diffuser assembly 212 therein. The nozzle outlet 480 is disposed as an opening at one end of the smaller diameter portion 474. The beverage dispensed from the modular beverage dispenser 100, 200 is dispensed at the nozzle outlet 480.

[0047] Beverages can be dispensed at a predetermined flow rate at the nozzle outlet 480. When the flow rate increases above 2 ounces per second (e.g., 2.5 ounces / second), the agitation within the nozzle 214 causes excessive foam to be produced in a conventional beverage dispenser. This is an undesirable effect for a beverage dispenser and should be reduced or preferably eliminated. The size and shape of the water diffuser 400 described herein are designed to reduce foaming when the flow rate is above 2 ounces / second. In some embodiments, this is achieved using an angled outlet on the water diffuser 400. According to various embodiments, the nozzle module 260 (including the nozzle 214 and the diffuser assembly 212) is configured to meet a set of predetermined improvement requirements for foaming, mixing, and dripping standards.

[0048] The diffuser base 410 may include a central inlet 446 and a plurality of diffuser inlets 442 disposed around the central inlet 446 on a top surface 401 of the diffuser base 410 that faces the dispensing surface 230 of the handle 208. The central inlet 446 may be aligned with the handle base fluid outlet 234, and the plurality of diffuser inlets 442 may be aligned with the plurality of handle mixed fluid outlets 232. The diffuser base 410 may include a central outlet 404 and a plurality of diffuser outlets 402 disposed around the central outlet 404 on a bottom surface 403 of the diffuser base 410 that is opposite to the top surface 401. The central opening may extend between the central inlet 446 and the central outlet 404. At least a portion of the water diffuser 400 (e.g., an elongated neck, as described below in conjunction with Figure 5 The handle base fluid outlet 234 may be disposed in the central opening of the diffuser base 410. The base fluid dispensed at the handle base fluid outlet 234 may flow through the inlet 424 of the water diffuser 400 to be dispensed at the outlet 406 (including the secondary outlet 408 when provided) of the water diffuser 400. The mixed fluid dispensed at the handle mixing fluid outlet 232 may be dispensed at one or more diffuser outlets 402 of the diffuser base 410. According to various embodiments, one or more of the diffuser outlets 402 may have different sizes, dimensions, and / or opening diameters to accommodate different mixing ratios of different flavor characteristics of beverages dispensed using the beverage dispensers described herein.

[0049] Diffuser passage 450 (eg Figure 6C 446 ) can extend between each diffuser inlet 442 and each diffuser outlet 402. A plurality of diffuser channels 450 can be arranged around a central inlet 446 of the diffuser base 410. A diffuser flow insert 216 can be disposed in each diffuser channel 450. The diffuser flow insert 216 can be retained within the diffuser channel 450 due to a friction fit. The diffuser flow insert 216 reduces the flow rate of the mixed fluid flowing through each diffuser outlet 402. According to various embodiments, the beverage dispenser 100, 200 does not throttle the base fluid (e.g., water). The diffuser flow insert 216 balances the flow rate (and therefore the ratio) of the mixed fluid (e.g., additives, syrup) and the base fluid (e.g., water) for various recipes (e.g., a ratio of 5 to 1 for sugary beverages, a ratio of 5 to 1 for diet beverages, and a ratio of 8.5 to 1 for diet products).

[0050] According to various embodiments, each diffuser flow insert 216 may include a nozzle or orifice therein. The opening of the nozzle or orifice is smaller than the inner diameter of the diffuser flow insert 216. The nozzle of the orifice of the diffuser flow insert 216 is located at a portion of the diffuser flow insert 216 that remains within the diffuser passage 450.

[0051] In some embodiments, the diffuser flow inserts 216 may be elongated such that they are longer than the diffuser passages 450 and extend beyond the diffuser outlet 402 of the diffuser base 410 , as shown in FIG. Figure 7B That is, the diffuser flow insert 216 extends through the bottom surface 411 of the water diffuser 400 so that the output of the diffuser flow insert 216 is downstream of the output of the water diffuser 400. In those embodiments, one or more mixing fluids may flow through the diffuser inlet 442 of the diffuser base 410 and the diffuser flow insert 216 to be dispensed below the outlet of the water diffuser 400 at the outlet 478 of the diffuser flow insert 216 to mix with the base fluid dispensed into the nozzle at the outlet of the water diffuser 400. The mixed beverage is then dispensed at the nozzle outlet 480. In these embodiments, the water flow begins upstream of the mixing fluid, and the mixing fluid is injected into the water flow dispensed from the outlet 406 of the water diffuser 400.

[0052] In some embodiments, the diffuser flow inserts 216 may be elongated such that they are shorter than the diffuser passages 450 and do not extend beyond the diffuser outlet 402 of the diffuser base 410 , as shown in FIG. Figure 6C That is, the outlet of the diffuser flow insert 216 is located upstream of the outlet of the water diffuser 400. In those embodiments, one or more mixing fluids can flow through the diffuser inlet 442 of the diffuser base 410 and the diffuser flow insert 216 to be dispensed at the diffuser outlet 402 of the diffuser base 410 above the outlet of the water diffuser 400 to mix with the base fluid dispensed at the outlet of the water diffuser 400 in the nozzle. The mixed beverage is then dispensed at the nozzle outlet 480.

[0053] Figure 5A perspective view 500 and a transparent cross-sectional view 502 of an exemplary water diffuser 400 according to various embodiments are shown. The water diffuser 400 may include an elongated neck 415 configured to fit into a central opening of a diffuser base 410. A first tapered surface 412 may be disposed at a first end 405 of the elongated neck 415. A second tapered surface 414 may be disposed below the first tapered surface 412. In some embodiments, a flat surface may connect the first tapered surface 412 and the second tapered surface 414. The taper angle of the first tapered surface 412 may be opposite to the taper angle of the second tapered surface 414. A set of angled outlets 406 configured to dispense water may be disposed along the second tapered surface 414. The angled outlets 406 may be placed at a predetermined angle to reduce foaming caused by a high flow rate (e.g., greater than 2.5 ounces per second) of water flowing through the water diffuser 400. The number of angled outlets 406 may also be determined based on foaming (eg, more angled outlets 406 may further reduce undesirable foaming).

[0054] The water diffuser 400 may include a recess 416 disposed below the second end 425 of the elongated neck 415. When the water diffuser 400 is coupled to the diffuser base 410 to form the diffuser assembly 212, the elongated neck 415 extends through the central inlet 446 of the diffuser base 410 such that the recess 416 remains above the top surface 401 of the diffuser base 410. When the diffuser assembly 212 is coupled to the handle 208, the recess 416 passes through the handle base fluid outlet 234 such that the inlet 424 of the water diffuser 400 is fluidly connected to the handle base fluid outlet 234. The recess 416 is received within the handle base fluid outlet 234 to maintain the chamber 235 ( Figure 7C .

[0055] Water received at the inlet 424 of the water diffuser 400 flows through the internal passage 422 extending along the elongated neck 415. The internal passage 422 extends between the inlet 424 and the angled outlet 406. A plurality of passages 426 extend at an angle between the internal passage 422 and the angled outlet 406. The plurality of passages 426 transport water from the internal passage 422 to the angled outlet 406. The base fluid (e.g., water) dispensed at the handle base fluid outlet 234 is received at the inlet 424, flows through the internal passage 422, and flows through the plurality of passages 426 for dispensing at the angled outlet 406.

[0056] A drip-proof gasket 420 (e.g., a sheet check valve) may be provided at the first end 405 of the elongated neck 415. The drip-proof gasket 420 is provided above the end of the internal passage 422 opposite to the inlet 424 that connects the handle base fluid outlet 234 to the internal passage 422. A plurality of channels 426 are provided downstream of the drip-proof gasket 420. The drip-proof gasket 420 is configured to prevent dripping from the water diffuser 400. For example, the water diffuser 400 including the drip-proof gasket 420 has less than 0.5 grams of dripping per 30 seconds (e.g., one drop is about 0.1 grains) under normal system operating conditions. That is, the beverage dispenser described herein has less than or equal to 5 drops when dripping after pouring. The remaining droplets remain in the handle 208. In some embodiments, one or more cutouts may be formed on the drip-proof gasket 420. For example, the cutouts on the drip-proof gasket 420 may transform the drip-proof gasket into 4 gaskets.

[0057] In some embodiments, a spring loaded ball check valve can be coupled to the water diffuser 400 as an anti-drip device. When the spring loaded ball check valve is closed, the pressure is released and the spring loaded ball check valve snaps in and captures all liquid on it. The flow path after the spring loaded ball check valve can be streamlined so that when the spring loaded ball check valve is closed, all liquid flows out and no liquid remains in the beverage dispenser 200.

[0058] In some embodiments, water isolation technology is used to prevent dripping, where carbonated water flows down the center of the water diffuser 400 inside a top flow track and still water flows around a center column in a series of ports whose diameters may decrease through the handle 208 and diffuser assembly 212. In the water isolation technology, most or all of the stagnant areas are removed so that no water remains in the modular handle 208 when the button 202 is released.

[0059] In such Fig. 6A and 6B In some of the illustrated embodiments, the water diffuser 400 may also include an additional set of angled outlets 408 configured to distribute water provided along the first tapered surface 412 upstream of the angled outlet 406. Water admitted at the inlet 424 of the water diffuser 400 flows through an internal passage 422 extending along the elongated neck 415. The internal passage 422 extends between the inlet 424 and the angled outlet 406 and the additional angled outlet 408. A plurality of passages 426 extend at an angle between the internal passage 422 and the angled outlet 406. Additional passages 436 (e.g., angular channels) extending at an angle are provided between the internal passage 422 and the additional angled outlet 408. Figure 6B406 and the set of additional angled outlets 408, respectively. The base fluid (e.g., water) dispensed at the handle base fluid outlet 234 is received at the inlet 424, flows through the internal channel 422, flows through the plurality of channels 426 for dispensing at the angled outlet 406, and flows through the additional channels 436 for dispensing at the additional angled outlet 408 upstream of the angled outlet 406. For example, the upper flow from the additional angled outlet 408 rinses the upper portion 470 or 472 of the nozzle 214, while the lower flow from the angled outlet 406 agitates the mixed fluid (from the diffuser outlet 402 of the diffuser base 410) and delivers the beverage out of the nozzle 214.

[0060] Figures 7B to 7C Shows Fig. 7A Various cross-sectional views of an exemplary modular beverage dispenser 700 are shown. Figures 7B to 7D A multi-layer flow track 702 is shown disposed within the handle 208 of a beverage dispenser 700. According to some embodiments, the handle 208 may include a channel (e.g., a flow track) 702 arranged along a horizontal layer. Each horizontal layer may extend along a plane that is parallel to the plane in which the remaining layers extend. According to various embodiments, the flow track may be distributed between four or more layers stacked on top of each other within the handle 208. In some embodiments, the flow track may include a first portion extending along a first layer and a second portion extending along a second layer parallel to the first layer. That is, the flow track may include a step, wherein the fluid flowing in the flow track flows along the first layer within the first portion of the handle and flows along the second layer within the second portion of the handle.

[0061] Each flow track 702 can form a flow channel that includes an inlet port 704 coupled to the tube assembly 210 via a mechanical gasket (e.g., O-ring) 265 disposed around the tube assembly 210. The mechanical gasket prevents leakage and provides an improved fit between the inlet port 704 of the flow track 702 and the outlet (e.g., opening) of the tube assembly 210. The fluid flowing in the tube assembly 210 flows through the flow track 702 to the dispensing surface 230 of the handle 208. In some embodiments, one or more flow tracks 702 can be provided with visual cues (e.g., color coding, markings) indicating the fluid flowing therein.

[0062] The flow tracks 702 on each layer can be connected to the handle base fluid outlet 234 and the handle mixing fluid outlet 232 of the handle 208. As described above, the handle base fluid outlet 234 of the handle 208 is in fluid communication with the central outlet 404 of the diffuser base 410 that receives the water diffuser 400. Therefore, the base fluid (e.g., water) flowing in the handle base fluid outlet 234 of the handle 208 flows through the central outlet 404 of the diffuser base 410 and is dispensed at the angled outlet 406 of the water diffuser 400. The mixing fluid (e.g., additive, syrup) flowing through one or more handle mixing fluid outlets 232 of the handle 208 flows through the diffuser outlet 402 of the diffuser base 410. The base fluid and the one or more mixing fluids are mixed in the nozzle 214 and dispensed at the nozzle outlet 480 of the beverage dispenser. According to various embodiments, the beverage can be dispensed at a flow rate of at least 2.5 ounces / second at the nozzle outlet 480.

[0063] Figures 8A to 8E Various configurations of multi-layer flow tracks (eg, four or more) of a handle of an exemplary beverage dispenser are shown according to various embodiments. Fig. 8A The first configuration 800 shown includes flow tracks 702 distributed among multiple layers. Figure 8B The second configuration 810 shown includes flow tracks 702 distributed among multiple layers. Figure 8C The third configuration 820 shown includes flow tracks 702 distributed between 3 layers. Fig.8D and 8E Top views of different track structures 830, 840 are shown respectively.

[0064] In some embodiments, a configuration with a lower number of layers provides a reduced number of layer changes for the flowing fluid, which can increase the flow rate of the flowing fluid. According to various embodiments, the flow track 702 can include rounded corners (e.g., rounded interior corners) rather than sharp corners and increase the track cross-sectional area compared to conventional beverage dispenser flow tracks.

[0065] like Figures 8A to 8C As shown, the flow track 702 can include a vertical portion 804 that allows the flow track 702 to be placed along two separated layers. Using the vertical portion 804, the fluid flowing in the flow track 702 can flow downward or upward between the two layers. That is, although the layers extend parallel to each other, the flow track 702 can cross the layers.

[0066] According to some embodiments, the top and bottom layers of the track configuration can be composed of flow tracks for base fluids (e.g., water, carbonated water, soda water). The middle layer (e.g., one or two layers in the middle) can be composed of flow tracks for mixed fluids (e.g., additives, syrup). In some embodiments, one of the middle layers can be removed, and for the base fluid, the cross-sectional area of ​​the flow tracks at the upper and lower layers can be increased. For example, in the first configuration 800 having four layers, the handle body can have a smaller profile than the second configuration 810 having five layers. In some embodiments, the first configuration 800 can have a smaller number of flow tracks than the second configuration 810.

[0067] Figures 9A to 12B Pressure traces of the flow path of a handle of an exemplary beverage dispenser are shown using computational fluid dynamics (CFD) to illustrate fluid flow according to various embodiments.

[0068] Fig.9A A first pressure trajectory 300 is shown within a handle of an exemplary beverage dispenser including a 5-layer flow track for mixing a fluid (eg, syrup) 302 and a first type of base fluid (eg, soda) 304 in accordance with various embodiments. Fig. 9B A second pressure trajectory 310 is shown within the handle of an exemplary beverage dispenser according to various embodiments, the beverage dispenser including a 5-layer flow track for a mixing fluid (e.g., syrup) 302 and a second type of base fluid (e.g., water) 304. When the base fluid is provided to the flow track inlet 704 at a higher pressure than the mixing fluid, the pressure of the two fluids decreases along the flow track while the fluids flow from the inlet 704 of the flow track 702 to the dispensing surface 230 of the handle 208. Once the base fluid is dispensed at the angled outlet 406 of the water diffuser 400, the trajectory of the base fluids 304, 306 branches into multiple trajectories 308.

[0069] Fig. 10A A first pressure trajectory 320 is shown within a handle of an exemplary beverage dispenser including a 4-layer flow track for mixing a fluid (eg, syrup) 302 and a first type of base fluid (eg, soda) 304 in accordance with various embodiments. Fig. 10B FIG. 3 shows a second pressure track 330 within a handle of an exemplary beverage dispenser according to various embodiments, the beverage dispenser including a 5-layer flow track for mixing a fluid (e.g., syrup) 302 and a second type of base fluid (e.g., water) 304. Figures 9A to 9B Compared to the 5-layer flow track shown in Figures 10A to 10B The 4-layer flow track shown in resulted in a 92% increase in total flow. Experiments conducted using two flow track configurations are shown in Table 1: Table 1

[0070] Figures 11A to 11B Fluid circulation within a nozzle module of a beverage dispenser according to various embodiments is shown. A first configuration 350 shows a conventional diffuser that provides a certain layer of circulation within the nozzle due to the angle of the diffuser. A second configuration 360 shows a nozzle module 260 according to an embodiment described herein that provides substantially more and better circulation within the nozzle module 260, resulting in better mixing of the base fluid and the mixing fluid at the tip of the nozzle 214. Embodiments achieve better mixing within the nozzle module 260 by changing the mixing fluid and base fluid discharge orientation at the diffuser base 410 and water diffuser 400, respectively, and using an elongated diffuser flow insert 216 to eject the mixing fluid below the base fluid discharge.

[0071] Figures 12A to 12B Pressure traces through nozzle modules of a beverage dispenser according to various embodiments are shown. A first configuration 370 shows a first nozzle module according to an embodiment described herein and a second configuration 380 shows a second nozzle module. As shown, moving the mixed fluid discharge outlet to the diffuser transfers the pressure loss from the manifold outlet to the diffuser inlet. Reducing the surface area at the mixed fluid inlet results in an increase in the inlet pressure. Tube Collector

[0072] Embodiments further provide a tube collector configured to be releasably coupled to a manifold. When portions of the tube collector and / or manifold require maintenance, they can be easily separated from each other. The manifold can in turn be coupled to multiple fluid sources. Thus, the tube collector can effectively couple multiple fluid sources to a beverage dispenser, such as beverage dispensers 100, 200 described herein.

[0073] Fig.13 A mechanism including a tube collector and a manifold is shown according to various embodiments. The tube collector 600 is releasably coupled to the manifold 604 located on the manifold tray 640, thereby forming a tube collector mechanism. Therefore, when parts of the tube collector 600 and / or the manifold 604 need to be repaired, they can be easily separated from each other. The tube collector 600 may include a handle 654, which when operated can release the tube collector 600 and the manifold 604 (located on the manifold tray 640) from each other.

[0074] The manifold 604 can in turn be coupled to a plurality of fluid sources. Thus, the tube collector 600 can effectively couple a plurality of fluid sources to a beverage dispenser (e.g., beverage dispensers 100, 200, also referred to as "bar guns"). The manifold 604 can be a multi-spec manifold including a plurality of continuous flow valves (CFVs) 602 that provide a constant rate of fluid flow at a preset pressure. A toggle key 606 can be coupled to each CFV 602 to open or close the corresponding CFV 602. The CFV 602 can operate at full throttle with fluid passing unrestricted, but the CFV 602 still uses a spring and baffle system to regulate pressure.

[0075] The manifold 604 may include a plurality of fixed orifices 608. According to different embodiments, the orifices 608 may have different sizes, dimensions and / or openings to accommodate different mixing ratios of different flavor characteristics of beverages dispensed using the beverage dispenser described herein. Multiple CFVs 602 regulate the pressure so that a fixed pressure is present at the output of the manifold 604. For a base fluid (e.g., water, soda), the pressure may be set to enter at about 100 psi, and a mixing fluid (e.g., additives, syrup) may enter at 50 to 60 psi, which is then regulated by the corresponding CFV 602 so that the pressure of the mixed fluid is about 30 psi at the inlet port 704 of the handle 208 of the beverage dispenser 200.

[0076] Fig.14 An exploded view of a tube collector according to various embodiments is shown. The tube collector 600 includes an angular housing having a top cover 612 and a bottom cover 614 that enclose a release mechanism 618 therebetween. According to various embodiments, the release mechanism 618 can be an elongated frame extending parallel to the top cover 612 and the bottom cover 614. The release mechanism 618 can include arms 615 extending on opposite sides of the release mechanism 618. The arms 615 can be configured to slide forward and backward along or within a set of guide rails 625.

[0077] The top cover 612 of the tube collector 600 may include a plurality of concave grooves 670, and the bottom cover 614 may include a plurality of convex grooves 672. The concave grooves 670 and the convex grooves 672 form a plurality of openings configured to receive a plurality of tubes extending between one or more fluid sources and a manifold 604 that may be releasably coupled to the tube collector 600.

[0078] The lever 620 may include a handle 654 disposed above the top cover 612 of the angled housing, and a guide arm 656 extending through an opening 652 on the top cover 612 of the angled housing. The guide arm 656 of the lever 620 is coupled to the release mechanism 618. The lever 620 and the release mechanism 618 form a disconnect mechanism that, when activated, moves forward and extends away from the front end of the tube collector 600. The lever 620 and the release mechanism 618 may form a quick disconnect mechanism.

[0079] The handle 654 can be pulled upward and / or backward to release the tube collector 600 from the manifold 604 (releasably coupled to the manifold tray 640) connected to the tube collector 600. The manifold tray 640 may include a plurality of manifold slots 671 extending parallel to each other. The manifold slots 671 may accommodate the manifold 604 therein. The manifold tray 640 may be releasably coupled to the front end of the tube collector 600. When the disconnection mechanism is activated, the tube collector 600 is disconnected from the manifold tray 640 by pushing the manifold tray 640 or the tube collector 600 away from each other. For example, one or more tabs 642 may be provided on the first end of the manifold tray 640. The tabs 642 may extend through one or more tab slots 678 provided on the bottom cover 614 of the tube collector 600 to connect (e.g., abut, physically contact) with the release mechanism 618. When the release mechanism 618 is activated, the release mechanism 618 pushes against one or more tabs 642 to disconnect the tube collector 600 from the manifold tray 640 .

[0080] According to various embodiments, the release mechanism 618 can be activated using a handle 654. When pulled, the handle 654 moves the release mechanism 618 along the rail 625, and the end protrusion 626 of the rail 625 will push against the tab 642 (e.g., Fig.16D 17 (showing the tube collector 600 in a fully assembled state) and FIG. 18 (showing the tube collector 600 without the top cover 612, thereby showing the release mechanism 618).

The guide arm 656 extends through the opening 652 on the top cover 612 and is connected to the release mechanism 618. For example, the guide arm 656 can be coupled to the rear end of the release mechanism 618. When the handle 654 is pulled, the guide arm 656 pushes the release mechanism 618 forward along the guide rail 625. The release mechanism 618 moves forward parallel to the top cover 612 and away from the top cover 612.
