Description

Technical Field

[0001] The present disclosure relates generally to fluid systems, and more particularly to fluid nozzles for use in fluid systems. Background Art

[0002] Vehicles such as automobiles typically include multiple exterior panels attached to a frame or chassis. One or more gaps that exist between such panels may be filled with a seam sealant to prevent moisture, dirt, etc. from entering the engine or passenger compartment of the vehicle through the gaps. Such seam sealants may also provide sound deadening for the vehicle. When one or more of these panels need to be replaced, the gaps between the panels are resealed by a technician. Typically, the seam seals have a unique appearance or pattern associated with the original manufacturer of the vehicle. When replacing these seam seals, a technician may desire to replicate the appearance or pattern of the original seam seal.

[0003] The ability to replicate an OEM applied seam seal may require the use of a spray applicator and materials used in or with a particular type of spray applicator. This phenomenon may require multiple spray applicators, fluid nozzles, and materials. Spray applicators are often expensive and can be difficult to clean. Additionally, an additional applicator may be required to apply some material prior to applying the spray texture or bead pattern.

[0004] Usually, the twin-barrel system for spraying the fluid mixture containing two fluid components comprises a twin-barrel barrel unit or other sources (for example, five-gallon buckets, five fifty-five-gallon buckets) containing two fluid components, is connected to a disposable static mixer of a fluid nozzle and is connected to an air manifold of a pressurized air supply source. Alternatively, the mono-barrel system for spraying a single fluid component generally comprises a mono-barrel barrel unit or other sources comprising a single fluid component, is connected to a fluid nozzle of a mono-barrel barrel unit and is connected to an air manifold of a pressurized air supply source. Usually, for a mono-barrel system, a static mixer is integrated with a fluid nozzle. Therefore, this type of fluid nozzle can not be used for a twin-barrel system. Generally speaking, the fluid nozzle that can be used for a twin-barrel system is different in design from the liquid nozzle that can be used for a mono-barrel system, thereby increasing the number of parts.

[0005] Currently, seam sealing applications require the purchase of separate fluid nozzles based on the type of application (such as single cartridge systems and dual cartridge systems), which can lead to confusion and mis-ordering, and can also result in longer wait times for repairs to be completed.

[0006] Seams and gaps are often filled with high viscosity fluids (e.g., using sealants) to prevent leakage of water, air, etc. For example, the gaps between various exterior panels of a vehicle (e.g., flanged panels) may be filled with seam sealants to prevent moisture, dirt, etc. from passing through the gaps. In downstream repairs or aftermarket applications, the gaps between such panels may need to be resealed by a technician. However, it is difficult for a technician to replicate or match the quality of a seal originally produced by expensive machines that are programmed to have precise specifications for pressure, flow, volume, temperature, timing, positioning, viscosity, etc.

[0007] In the field or in the repair shop, the potential for human error (e.g., inconsistent weld bead height, width, or uniformity) increases, especially for inexperienced technicians. Implementations often fall short of OEM capabilities, and this mismatch can be easily observed, such as in a repair assessment or insurance context. Therefore, improved technology is needed to reproduce a seal that does not increase time or material costs in repair or aftermarket restoration practices.

[0008] Current sealant applicators are not rotatable, i.e., the cross-section of the outlet of the sealant applicator is not consistent as the orientation of the sealant applicator changes. Additionally, current sealant applicators may not allow a user to comfortably hold the sealant applicator when applying sealant, and do not allow adjustment for the various contours and shapes of panels to which the sealant is applied.

[0009] Vehicles such as automobiles typically include multiple exterior panels connected to a frame or chassis. Gaps between these panels may be filled with seam sealants to prevent moisture, dirt, etc. from entering the engine and / or passenger compartment of the vehicle through the gaps. In some cases, such seam sealants may also provide sound deadening for the vehicle. When one or more panels need to be replaced, the user may reseal the gaps between these panels. In addition, when replacing a seam sealant, the user may desire to replicate the appearance or pattern of the original seam sealant.

[0010] There are various seam sealants available with different compositions and viscosities. Conventional fluid nozzles may not be suitable for use with different seam sealants. That is, conventional fluid nozzles may be specially designed and suitable for use with a single seam sealant product. In addition, when not used with the seam sealant for which they are specially designed, conventional fluid nozzles may not be able to replicate the appearance or pattern of the original seam sealant.

[0011] Therefore, there is a need for a fluid nozzle suitable for use with a variety of different seam sealants having different viscosities. In addition, there is a need for a fluid nozzle that can replicate the appearance or pattern of the original seam seal, regardless of the differences in the viscosities of the different seam sealants.

[0012] Seams and gaps are often filled with seam sealants to prevent leakage (e.g., of water, air, etc.). For example, gaps between various exterior panels of a vehicle (e.g., trim flange panels) may be filled with seam sealants to prevent moisture, dirt, etc. from passing through the gaps. In downstream repairs or aftermarket applications, gaps between such panels may be resealed by a technician. However, it may be difficult for the technician to replicate or match the quality of the original seal.

[0013] In some cases, a wide and / or flat applied seam sealant material may be required to replicate the original seal with a wide and / or flat appearance. In such applications, machining or painting the applied material to achieve the wide and / or flat appearance may result in air entrapment or contamination before the seam sealant cures. This may also negatively impact subsequent paint applications. Summary of the invention

[0035] In the following description, reference is made to the accompanying drawings which form a part thereof, and in which various embodiments are shown by way of illustration. It should be understood that other embodiments can be envisioned and made without departing from the scope or essence of the present disclosure. Therefore, the following specific embodiments should not be considered to have a limiting meaning.

[0036] In the following disclosure, the following definitions apply.

[0037] As used herein, all numbers should be considered to be modified by the term "about". As used herein, "a", "an", "said", "at least one" and "one or more" are used interchangeably.

[0038] Unless specifically defined otherwise, the term "about" means a close approximation (eg, within + / - 5% for a quantifiable property), but again does not require absolute precision or a perfect match.

[0039] As used herein, as a modifier of a characteristic or property, unless otherwise specifically defined, the term "substantially" or "generally" means that the characteristic or property would be readily discernible by a person of ordinary skill without requiring absolute precision or a perfect match (e.g., within + / - 20% for a quantifiable characteristic).

[0040] Unless specifically defined otherwise, the term "substantially" means a high degree of approximation (eg, within + / - 10% for a quantifiable characteristic), but again does not require an absolutely precise or perfect match.

[0041] Terms such as same, equal, uniform, constant, exact, etc. should be understood to mean within normal tolerances, or within measurement errors applicable to the particular circumstances, rather than requiring absolute precision or a perfect match.

[0042] As used herein, the terms "first" and "second" are used as identifiers. Therefore, such terms should not be understood as limitations on the present disclosure. Throughout the embodiments of the present disclosure, the terms "first" and "second" are interchangeable when used in conjunction with a feature or element.

[0043] As used herein, when a first material is referred to as being "similar" to a second material, at least 90 weight percent of the first and second materials are identical, and any variation between the first and second materials accounts for less than about 10 weight percent of each of the first and second materials.

[0044] As used herein, “at least one of A and B” should be understood to mean “only A, only B, or both A and B”.

[0045] As used herein, the recitations of numerical ranges by endpoints include all numbers subsumed within that range as well as the endpoints (eg, 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, etc.).

[0046] The term "coupled" or "connected" may include a direct physical connection between two or more components, or an indirect physical connection between two or more components connected together by one or more additional components. For example, a first component may be coupled to a second component by being directly connected together or by being connected by a third component.

[0047] Unless specified or limited otherwise, the terms "attach," "connect," "couple" and variations thereof are used broadly and encompass both direct and indirect attachments, connections and couplings.

[0048] As used herein, the term "configured to" and similar terms are at least as restrictive as the term "adapted to" and require actual design intent to perform the specified function, not just the physical ability to perform such function.

[0049] As used herein, the term "elastic deformation" refers to the elastic deformation of a component or a portion of a component when a force is applied. When a component is elastically deformed, it may be in a deformed state. The component may not be plastically deformed in the deformed state. After the force is removed, the component may return to its undeformed state. The force may be applied by another component. The degree of elastic deformation may depend on the amount of force applied.

[0050] Generally, the present disclosure provides various embodiments of fluid nozzles and fluid systems including fluid nozzles. The fluid nozzle may include a tube and a manifold disposed about the tube. Typically, original equipment manufacturer (OEM) seam sealing techniques require a time-consuming manual process to provide a seam seal that is similar to the original factory-applied seam seal. Such processes include using hand tools to physically create specific textures and patterns by manually changing the appearance. In addition, such processes include using comb tools, modified plastic body filler spreaders, Scotch Brite®, etc. after dispensing the sealant onto the surface. TM abrasive pads or other tools; physically changing the dispensing by movement of the applicator, regulating air pressure using a trigger of a pneumatic applicator, or application of physical pressure of a manual applicator. Other techniques may also include, but are not limited to, cutting or manipulating the dispensing nozzle or selecting the various sealing materials used.

[0051] Usually, the twin-barrel system for spraying the fluid mixture containing two fluid components comprises a twin-barrel barrel unit or other sources (for example, five-gallon buckets, five fifty-five-gallon buckets) containing two fluid components, a disposable static mixer connected to a fluid nozzle and an air manifold connected to a pressurized air supply source. Alternatively, the mono-barrel system for spraying a single fluid component generally comprises a mono-barrel barrel unit or other sources comprising a single fluid component, a fluid nozzle connected to a mono-barrel barrel unit and an air manifold connected to a pressurized air supply source. Usually, for a mono-barrel system, a static mixer is integrated with the fluid nozzle. Therefore, this type of fluid nozzle can not be used for a twin-barrel system. Generally speaking, the fluid nozzle that can be used for a twin-barrel system is different in design from the liquid nozzle that can be used for a mono-barrel system, thereby increasing the number of parts. At present, the seam sealing application needs to purchase a separate fluid nozzle based on the type (such as a mono-barrel system and a twin-barrel system) applied, and may cause confusion and wrong ordering, and the waiting time to complete maintenance is longer.

[0052] Therefore, there is a need for a fluid nozzle that is interchangeably connectable to both a single cartridge system and a dual cartridge system, thereby reducing the number of parts and increasing the efficiency of the fluid system including the fluid nozzle.

[0053] The present disclosure provides a fluid nozzle. The fluid nozzle includes a tube, the tube including a first tube end and a second tube end opposite to the first tube end. The tube extends along a tube axis defined between the first tube end and the second tube end. The tube includes an inlet defined at the first tube end. The tube includes an outlet defined at the second tube end. The tube also includes a fluid passage disposed in the tube and extending from the inlet to the outlet. The tube also includes a first portion, the first portion including an outlet. The first portion extends from the second tube end toward the first tube end along the tube axis. The first portion at least partially defines a fluid passage therein. The tube also includes a second portion, the second portion including an inlet. The second portion extends from the first portion to the first tube end along the tube axis. The second portion at least partially defines a fluid passage therein. The second portion is configured to be selectively and removably connected to a first fluid source. The tube also includes a third portion extending from the first tube end toward the second tube end along the tube axis. The third portion at least partially surrounds and is connected to the second portion. The third portion includes a cylindrical segment extending along the length of the third portion and at least one first coupling element disposed on the cylindrical segment. The fluid nozzle also includes an adapter configured to selectively and removably connect to a third portion of the tube when the first fluid source is disconnected from the second portion of the tube. The adapter defines an adapter channel that is in fluid communication with the fluid passage when the adapter is connected to the third portion of the tube. The adapter is configured to be removably connected to a second fluid source different from the first fluid source. The adapter includes a first adapter end, a second adapter end opposite to the first adapter end, an adapter axis extending between the first adapter end and the second adapter end, an inner surface, and an outer surface. The adapter is configured to at least partially receive the third portion of the tube therein through the first adapter end. The adapter includes at least one second coupling element disposed on an inner surface proximate to the first adapter end and extending angularly around the adapter axis. The at least one second coupling element is configured to at least partially receive at least one first coupling element of the third portion therein to form a snap-fit ​​connection between the adapter and the third portion. When connected to the adapter, the tube is capable of rotating relative to the adapter about the tube axis.

[0054] The fluid nozzle of the present disclosure can be used to dispense high viscosity materials. The fluid nozzle as described herein can be used interchangeably with a single-barrel system and a dual-barrel system. More specifically, the present invention provides a modular fluid nozzle that can be quickly and easily connected to a mixer by a press fit. The mixer can then be connected to a dual-barrel cartridge unit. Alternatively, the modular fluid nozzle can be quickly and easily connected to an adapter by a snap fit. In addition, the adapter can be threadedly connected to the single-barrel cartridge unit. Since the modular fluid nozzle can be connected to two types of fluid systems, the costs associated with handling and manufacturing fluid nozzles with different numbers of parts can be eliminated. In addition, the fluid nozzle can be disposable, thereby eliminating the time required for cleaning and the additional costs associated with cleaning solutions. In addition, the fluid nozzle can be connected to air manifolds and nozzle spray tips of different designs.

[0055] Furthermore, the fluid nozzles of the present disclosure can reduce the number of applicators (more specifically, fluid nozzles) required to perform seam sealing applications to replicate OEM style and appearance while improving application efficiency, reducing waste, and creating a unique no-clean solution for both single-barrel and dual-barrel systems.

[0056] Now refer to the accompanying drawings, Figure 1A A perspective view of a fluid nozzle 100 is shown. The fluid nozzle 100 includes a tube 102. The fluid nozzle 100 may also include a manifold 104 that can be selectively connected to the tube 102. In some examples, the tube 102 is a single, unitary component. The tube 102 includes a first tube end 106 and a second tube end 108 opposite the first tube end 106. The tube 102 extends along a tube axis A1 defined between the first tube end 106 and the second tube end 108. The tube 102 includes an inlet 110 defined at the first tube end 106. The fluid F1 (see Figure 7 ) or fluid mixture F2 (see Figure 2 ) can be received within the tube 102 via the inlet 110. As used herein, the term "fluid mixture" may include a combination of two different fluids that may be mixed by a mixer 204 (e.g., Figure 2 The tube 102 also includes an outlet 112 (as shown) defined at the second tube end 108. Figure 3 1 ). The fluid F1 or the fluid mixture F2 may exit the tube 102 via the outlet 112. The tube 102 also includes a fluid passage 114 disposed within the tube 102 and extending from the inlet 110 to the outlet 112.

[0057] The tube 102 also includes a first portion 116, which includes an outlet 112. The first portion 116 extends from the second tube end 108 toward the first tube end 106 along the tube axis A1. The first portion 116 at least partially defines a fluid passage 114 therein. In some implementations, the first portion 116 is at least partially tapered in the flow direction D1 from the first tube end 106 to the second tube end 108. Specifically, the first portion 116 may include a first tapered portion 118 having a tapered cross section along the flow direction D1, a second uniform portion 120 having a uniform cross section, and a third tapered portion 122 having a tapered cross section along the flow direction D1. Each of the first tapered portion 118, the second uniform portion 120, and the third tapered portion 122 may include a circular cross section. Alternatively, the first tapered portion 118, the second uniform portion 120, and the third tapered portion 122 may include any other cross section, such as a square cross section. In other examples, the first portion 116 can include a circular cross-section along a segment of the first portion 116, and the first portion 116 can include a square cross-section along the remainder of the first portion 116. Furthermore, the first tapered portion 118 of the first portion 116 can include the outlet 112. Furthermore, the second uniform portion 120 can include a continuous rib 124 extending therefrom. In other examples, the second uniform portion 120 can include more than one continuous rib (similar to the continuous rib 124) without limitation.

[0058] The tube 102 also includes a second portion 126 that includes the inlet 110. The second portion 126 extends from the first portion 116 to the first tube end 106 along the tube axis A1. The second portion 126 includes a wall 129 that has a polygonal shape 128 along the length L1 of the second portion 126. The second portion 126 at least partially defines the fluid passage 114 therein. The second portion 126 is configured to selectively and removably connect to the first fluid source 202 (e.g., Figure 2 126). In some embodiments, the polygonal shape 128 of the second portion 126 is a square. In some other embodiments, the polygonal shape 128 of the second portion 126 may be a rectangle, a hexagon, a triangle, etc. The second portion 126 may be integral with the first portion 116. In some examples, the cross-sectional area of ​​the second portion 126 may be greater than the average cross-sectional area of ​​the first portion 116. In some embodiments, the second portion 126 may be configured to receive a segment of the mixer 204 in a sealed manner. In at least one embodiment, the first portion 116 may have a different cross-sectional shape relative to the second portion 126. For example, the first portion 116 may be circular and the second portion 126 may be rectangular / square. In at least one embodiment, the wall 129 may extend from the boundary between the first portion 116 and the second portion 126 to the second tube end 108.

[0059] The tube 102 also includes a third portion 130 extending along the tube axis A1 from the first tube end 106 toward the second tube end 108. The third portion 130 at least partially surrounds and is connected to the second portion 126. The third portion 130 includes a cylindrical segment 132 extending along a length L2 of the third portion 130 and at least one first coupling element 134 disposed on a wall of the cylindrical segment 132. The at least one first coupling element 134 is disposed proximate to the second portion 126 and away from the first tube end 106. Figure 1A In the illustrated embodiment, the third portion 130 includes a single first coupling element 134. However, the third portion 130 may include a plurality of first coupling elements (similar to the first coupling element 134) without limitation. Figure 1A In the illustrated embodiment, at least one first coupling element 134 comprises an annular rib. Specifically, the first coupling element 134 is a continuous annular rib extending around the tube axis A1. Alternatively, at least one first coupling element 134 may comprise one or more tabs or protrusions, one or more bosses, etc. extending from the third portion 130. It should be noted that the present disclosure is not limited by the shape or design of the first coupling element 134.

[0060] In addition, in some examples, the length L1 of the second portion 126 can be greater than the length L2 of the third portion 130. In some examples, the length L1 of the second portion 126 can be about twice the length L2 of the third portion 130. In addition, the polygonal shape 128 of the second portion 126 and the cylindrical segment 132 of the third portion 130 can be coaxial with each other. In some embodiments, the third portion 130 is connected to at least each vertex 136 of the polygonal shape 128 of the second portion 126 along the length L1 of the third portion 130. The second portion 126 can be integral with the third portion 130.

[0061] In some embodiments, the fluid nozzle 100 includes a manifold 104 that is configured to be removably connected to the first portion 116 of the tube 102 via a snap-fit ​​connection. The manifold 104 may include a first tubular portion 138 that extends along the first axis A2 and is configured to at least partially receive the first portion 116 of the tube 102 therein. The first tubular portion 138 may define an air outlet 140 (e.g., Figure 3140 ), the air outlet is disposed around the outlet 112 of the tube 102. The outlet 112 can be concentrically disposed within the air outlet 140. The first tubular portion 138 can include a first segment 142. The first segment 142 includes a uniform cross-section. In addition, the first segment 142 is similar in shape to the second uniform portion 120 of the first portion 116, so that when the manifold 104 is connected to the first portion 116, the first segment 142 can be disposed around the second uniform portion 120. In addition, the first segment 142 can include a circumferential groove 144 (as shown in FIG. Figure 5 14 and 15. As shown in FIG. 14A and 14B , the circumferential groove receives the continuous rib 124 of the second uniform portion 120 to form a snap-fit ​​connection between the first portion 116 and the manifold 104. During assembly of the tube 102 with the manifold 104, the continuous rib 124 can be compressed, which can promote a secure engagement of the manifold 104 and the tube 102 in a fluid-tight assembly. In some examples, the manifold 104 and the tube 102 can be connected to each other before being shipped to a customer, thereby facilitating the customer's use of the fluid nozzle 100. In addition, the first tubular portion 138 can include a second segment 146. The second segment 146 includes a tapered cross-section. In addition, the shape of the second segment 146 is similar to the first tapered portion 118 of the first portion 116, so that when the manifold 104 is connected to the first portion 116, the second segment 146 is disposed around the first tapered portion 118.

[0062] The fluid nozzle 100 may also include a second tubular portion 148 extending from the first tubular portion 138 along a second axis A3 that is inclined relative to the first axis A2. In some cases, the second axis A3 may be perpendicular to the first axis A2. The second tubular portion 148 may define an air inlet 150 that is disposed in fluid communication with the first tubular portion 138. The second tubular portion 148 may be designed for quick attachment to a pressurized air source (not shown) via an air supply hose (not shown). The first tubular portion 138 and the second tubular portion 148 may together define an air passage 152 (e.g., air inlet 150) and an air outlet 140. Figure 5 1 (shown), such that when connected to an air source, pressurized air can enter the manifold 104 via the air inlet 150, flow around the first portion 116, and exit the manifold 104 via the air outlet 140. In some examples, the manifold 104 can include a plurality of openings (not shown) through which pressurized air can be discharged to atomize the fluid F1 or fluid mixture F2 discharged from the tube 102.

[0063] Figure 1B A bottom view of a tube 102 is shown according to another embodiment of the present disclosure. Figure 1B In the illustrated embodiment of the present invention, the second portion 126 of the tube 102 includes a length L1 (see Figure 1A). The circular shape 154 of the second portion 126 can be configured to receive a segment of a mixer (not shown) for removably connecting the tube 102 to the mixer. In addition, the circular shape 154 can be concentrically disposed within the cylindrical segment 132. The circular shape 154 can be radially spaced apart from the cylindrical segment 132. Thus, the circular shape 154 can extend along the length L2 (see FIG. 14 ) of the third portion 130. Figure 1A ) is disconnected from the cylindrical segment 132.

[0064] Figure 2 2 shows a schematic cross-sectional view of a fluid system 200 according to an embodiment of the present disclosure. The fluid system 200 includes Figure 1A The fluid nozzle 100, the mixer 204 and the first fluid source 202. The mixer 204 can be embodied as a static mixing device. In at least one embodiment, the mixer 204 is a static mixing nozzle commercially available from 3M Company (St. Paul, Minnesota, USA). The tube 102 is configured to partially receive the mixer 204. More specifically, the second portion 126 of the tube 102 is configured to slidably receive the mixer 204 therein. In addition, the mixer 204 includes an elongated mixer tube 206. The mixer tube 206 can define a first mixer end 208 and a second mixer end 210. The shape of the mixer tube 206 corresponds to the polygonal shape 128 of the second portion 126. Therefore, in Figure 2 In the illustrated embodiment of , the mixer tube 206 has a polygonal shape corresponding to the polygonal shape 128 of the second portion 126. Figure 2 In the illustrated embodiment of the mixer tube 206, the mixer tube 206 includes a square shape. Alternatively, the mixer tube 206 may include a circular shape 154 corresponding to the second portion 126 (see Figure 1B ) in a circular shape.

[0065] It should be noted that when the fluid nozzle 100 is connected to the mixer 204, the fluid nozzle 100 cannot be rotated relative to the mixer 204. In such embodiments, the mixer 204 may have to be rotated relative to the first fluid source 202 to position the manifold 104 in a desired orientation. The mixer tube 206 may be engaged with the second portion 126 in a sealing manner to prevent fluid from leaking therefrom. In addition, when the mixer 204 is connected to the tube 102, the first mixer end 208 may be disposed within the second portion 126. The mixer 204 may include a plurality of baffle elements 212 to thoroughly mix the material passing through the mixer tube 206. In addition, the mixer 204 may be connected to the first fluid source 202 at the second mixer end 210. In addition, the mixer tube 206 may define a mixing chamber 214 at the first mixer end 208. In at least one embodiment, the tube 102 does not include a plurality of baffle elements.

[0066] exist Figure 2 In the illustrated embodiment, the first fluid source 202 is implemented as a double-barrel cartridge unit. The first fluid source 202 is detachably connected to the second portion 126 of the tube 102. The first fluid source 202 may include a first container 216 configured to accommodate the first fluid F3 and a second container 218 configured to accommodate the second fluid F4. The first fluid F3 and the second fluid F4 may include any suitable material, such as a seam sealant, epoxy resin, foam, adhesive (e.g., one-component or two-component adhesive), filler, etc. In addition, any suitable seam sealing material may be used, such as one-component and two-component seam sealants, polyurethane sealants, modified saltwater polymer sealants, two-component epoxy resin sealants, one-component and two-component acrylic sealants, viscous one-component or two-component moisture-proof sealants, ultraviolet curing (UV curing) sealants, blue light curing sealants, heat-activated sealants, etc. In addition, any suitable adhesive may be used, such as one-component and two-component acrylic adhesives, etc. In one or more embodiments, the first fluid F3 and the second fluid F4 form a fluid mixture F2, which may include a joint sealing composition suitable for sealing one or more joints provided between panels of a vehicle or a ship, or sealing joints present on an interior or exterior surface of a building.

[0067] In addition, the first fluid source 202 may include a cylindrical protrusion 220 in fluid communication with each of the first container 216 and the second container 218. The first fluid source 202 may include a plunger 228. The plunger 228 may be used to force the first fluid F3 and the second fluid F4 toward the mixer 204. Alternatively, the first fluid source 202 may not include the plunger 228, and the first fluid F3 and the second fluid F4 may be forced toward the mixer 204 by applying pressure on the first container 216 and the second container 218, such as by squeezing the first container 216 and the second container 218.

[0068] In some examples, the mixer 204 can be connected to the first fluid source 202 by a retaining nut 226. In these examples, each of the mixer tube 206 and the cylindrical protrusion 220 can include an external thread (not shown) that can be engaged with an internal thread (not shown) of the retaining nut 226 for connecting the mixer 204 to the first fluid source 202. In another embodiment, the mixer 204 can have an internal thread (not shown) that can be directly coupled to the first fluid source 202. In another embodiment, the mixer 204 can be connected to the first fluid source 202 by a press fit. It should be noted that the present disclosure is not limited by the technology of connecting the mixer 204 to the first fluid source 202.

[0069] Fluid system 200 can be connected with an applicator gun (not shown) to achieve seam sealing application. The applicator gun can include any conventional sprayable seam sealant applicator gun, such as those manufactured by 3M Company (St. Paul, Minnesota). The applicator gun can include a rod that can push a plunger 228 of the first fluid source 202 for guiding the first fluid F3 and the second fluid F4 toward the fluid nozzle 100. In addition, the applicator gun can be communicated with an air source. The applicator gun can also be connected to the manifold 104 through an air supply hose. The movement of the rod and the air supply rate entering the manifold 104 can be controlled by the applicator gun. The applicator gun can have a trigger. Pressing the trigger partially to the first position can allow air to pass toward the manifold 104. In addition, pressing the trigger completely to the second position will activate the rod to push the first fluid F3 and the second fluid F4 toward the mixer 204. The mixer 204 may mix the first fluid F3 from the first container 216 and the second fluid F4 from the second container 218 to form a fluid mixture F2 in the mixer 204. The fluid mixture F2 may be introduced into the fluid nozzle 100 via the inlet 110. Furthermore, the fluid mixture F2 may be ejected through the outlet 112 of the fluid nozzle 100.

[0070] See now Figure 3 The fluid nozzle 100 further includes an adapter 300 configured to be connected to the first fluid source 202 (see Figure 2 ) is selectively and removably connected to the third portion 130 of the tube 102 when disconnected from the second portion 126 of the tube 102. The adapter 300 includes a generally circular cross-section that corresponds to the circular cross-section of the cylindrical segment 132 of the third portion 130. The adapter 300 defines an adapter channel 302 (e.g., Figure 4 and Figure 5 ), when the adapter 300 is connected to the third portion 130 of the tube 102, the adapter channel is in fluid communication with the fluid passage 114. The adapter 300 is configured to be detachably connected to a second fluid source 702 (eg, Figure 7 The adapter 300 includes a first adapter end 304, a second adapter end 306 opposite to the first adapter end 304, an adapter axis A4 extending between the first adapter end 304 and the second adapter end 306, an inner surface 308 (as shown in FIG. Figure 4 ) and an outer surface 310. The adapter 300 is configured to at least partially receive the third portion 130 of the tube 102 therein via the first adapter end 304.

[0071] like Figure 4As shown, the adapter 300 includes at least one second coupling element 312 disposed on the inner surface 308 proximate the first adapter end 304 and extending angularly around the adapter axis A4. Figure 1A and Figure 4 , at least one second coupling element 312 is configured to at least partially receive at least one first coupling element 134 of the third part 130 therein to form a snap-fit ​​connection between the adapter 300 and the third part 130. The adapter 300 includes a single second coupling element 312 here. However, the adapter 300 may include a plurality of second coupling elements (similar to the second coupling element 312). In some embodiments, the at least one second coupling element 312 is a continuous groove extending 360 degrees around the adapter axis A4. In other embodiments, the at least one second coupling element 312 may include a plurality of second coupling elements that may be spaced apart from each other annularly. For example, the at least one second coupling element 312 may include a discontinuous groove. Alternatively, the at least one second coupling element 312 may include a combination of elements that allow the tube 102 to be coupled to the adapter 300, such as a wedge, an annular shoulder, a protrusion, etc. In some embodiments, at least one second coupling element 312 may include one or more L-shaped grooves 329 that may receive corresponding first coupling elements 134 of the third portion 130 for coupling the tube 102 with the adapter 300. It should be noted that the present disclosure is not limited by the shape or design of the second coupling element 312. In some embodiments, the first coupling element 134 may include a groove, and the second coupling element 312 may include an annular rib, a protrusion, a boss, etc. It should be noted that the adapter 300 and the tube 102 may be detachably connected to each other by any complementary set of coupling elements.

[0072] Furthermore, when connected with adapter 300, tube 102 can rotate relative to adapter 300 about tube axis A1. First coupling element 134 and second coupling element 312 can form a fluid-tight connection between tube 102 and adapter 300 while allowing tube 102 to rotate relative to adapter 300 about tube axis A1.

[0073] See also Figure 4 and Figure 5 , the adapter 300 may include one or more internal threads 314 extending from the second adapter end 306.

The narrow portion 318 may include an adapter channel 302 that is in fluid communication with the fluid passage 114 when the adapter 300 is connected to the tube 102. The adapter channel 302 is also disposed in fluid communication with the second fluid source 702 when the adapter 300 is connected to the second fluid source 702. Therefore, when the adapter 300 is connected to the tube 102 and the second fluid source 702, the adapter channel 302 can enable the fluid passage 114 of the tube 102 to be in fluid communication with the second fluid source 702. In some embodiments, the adapter 300 also includes a stepped portion 320 that connects the narrow portion 318 to the wide portion 316.

The wide portion 316 extends from the stepped portion 320 to the first adapter end 304 and includes the plurality of flexible castellations 328. In addition, the adapter body 326 is defined by the narrow portion 318, and a segment of the wide portion 316, and does not include the plurality of flexible castellations 328. In some embodiments, the plurality of flexible castellations 328 are angularly spaced from each other about the adapter axis A4 and define a plurality of slots 330 therebetween. In addition, each of the plurality of flexible castellations 328 can be configured to deform outwardly at least relative to the adapter axis A4 during connection of the third portion 130 to the adapter 300. In addition, in some embodiments, at least one second coupling element 312 is disposed adjacent to the plurality of flexible castellations 328, opposite the first adapter end 304.

[0076] In some embodiments, the number of the plurality of flexible castellations 328 is between three and ten. Figure 4 In the illustrated embodiment of the adapter 300, the adapter 300 includes four flexible castellations 328. In addition, in some embodiments, each of the plurality of slots 330 is U-shaped. The slots 330 can extend from the first adapter end 304 toward the at least one second coupling element 312. Figure 4 In the illustrated embodiment, the adapter 300 includes four slots 330 .

[0077] In some embodiments, each of the plurality of flexible castellations 328 includes a wedge-shaped surface 332 that forms a portion of the inner surface 308 and tapers outwardly in a direction D3 from the second adapter end 306 toward the first adapter end 304. Figure 4 In the illustrated embodiment of the adapter 300, the adapter 300 includes a plurality of wedge surfaces 332. The total number of wedge surfaces 332 corresponds to the total number of the plurality of flexible castellations 328. The at least one second coupling element 312 can be spaced apart from the wedge surfaces 332 relative to the adapter axis A4. In some embodiments, the wedge surfaces 332 are spaced apart from the at least one second coupling element 312 by a portion of the inner surface 308. However, in other examples, it is contemplated that the wedge surfaces 332 can extend to the at least one second coupling element 312.

The fluid system 700 includes Figure 1A The fluid nozzle 100, reference Figure 3 , Figure 4 and Figure 5The adapter 300 and the second fluid source 702 explained are shown in the figure. In addition, the fluid nozzle 100 is connected to the adapter 300 in a rotating manner. Therefore, by rotating the fluid nozzle 100 relative to the adapter 300, the manifold 104 can be simply set in any desired orientation. The second fluid source 702 is detachably connected to the adapter 300. The second fluid source 702 is embodied as a single barrel unit in this article. The second fluid source 702 may include a container 704 configured to accommodate fluid F1.

[0089] The adapter 300 is threadedly connected to the second fluid source 702. More specifically, the internal threads 314 of the adapter 300 can be engaged with the external threads (not shown) on the cylindrical protrusion 708 to connect the adapter 300 to the second fluid source 702. It should be noted that the present disclosure is not limited by the technology of connecting the adapter 300 to the second fluid source 702.

[0090] The fluid system 700 can be coupled to an applicator gun (not shown) to achieve a seam sealing application. The applicator gun can include any conventional sprayable seam sealant applicator gun, MN, such as those manufactured by 3M Company (St. Paul, Minnesota, USA). The applicator gun can include a rod that can push a plunger 710 of a first fluid source 702 for directing fluid F1 toward the fluid nozzle 100. In addition, the applicator gun can be connected to an air source. The applicator gun can also be connected to the manifold 104 via an air supply hose. The movement of the rod and the air supply rate into the manifold 104 can be controlled by the applicator gun. The applicator gun can have a trigger. Squeezing the trigger partially to a first position can allow air to pass toward the manifold 104. In addition, squeezing the trigger completely to a second position activates the rod to push the fluid F1 toward the fluid nozzle 100. The fluid F1 can be directed into the fluid nozzle 100 via the inlet 110 and the adapter channel 302. In addition, the fluid F1 can be ejected through the outlet 112 of the fluid nozzle 100.

Figure 2 and Figure 8 , at step 802, the second portion 126 of the tube 102 is interchangeably connected to the mixer 204 of the first fluid source 202. At step 804, the mixer 204 is connected to the first container 216 of the first fluid source 202 and the second container 218 of the first fluid source 202. At step 806, the first fluid F3 from the first container 216 and the second fluid F4 from the second container 218 are mixed in the mixer 204 to form a fluid mixture F2. At step 808, the fluid mixture F2 is directed into the inlet 110 of the fluid nozzle 100. At step 810, the fluid mixture F2 is ejected through the outlet 112 of the fluid nozzle 100.

[0092] Fig. 9 A flow chart of a method 900 of using the fluid nozzle 100 is shown. Figure 7 and Fig. 9 At step 902, the third portion 10 of the tube 102 is interchangeably connected to the adapter 300 by rotating the tube 102 about the tube axis A1. At step 904, the adapter 300 is connected to the second fluid source 702. At step 906, the fluid F1 from the second fluid source 702 is directed into the inlet 110 of the fluid nozzle 100 via the adapter channel 302. At step 908, the fluid F1 is ejected through the outlet 112 of the fluid nozzle 100.

[0093] Thus, the fluid nozzle 100 can be interchangeably connected to the first fluid source 202 containing two fluid components and the second fluid source 702 containing a single fluid component, thereby reducing the number of parts and improving the efficiency of the fluid systems 200, 700, respectively. In addition, the fluid nozzle 100 can be interchangeably connected to the first fluid source 202 via the mixer 204 and to the second fluid source 702 via the adapter 300, 600 (see Figure 4 and Figure 6 ) can be interchangeably connected to a second fluid source 702 without any changes to the structure of the fluid nozzle 100. In addition, the present disclosure can reduce the number of applicators (more specifically, fluid nozzles) required to perform seam sealing applications to replicate OEM styles and appearances, while increasing application efficiency, reducing waste, and creating a unique no-clean solution for the fluid systems 200, 700.

[0094] Since the modular fluid nozzle 100 can be connected to two different fluid sources 202, 702, the costs associated with handling and manufacturing fluid nozzles with different part counts can be eliminated. In addition, the fluid nozzle 100 can be disposable, thereby eliminating the time required for cleaning and the additional costs associated with cleaning solutions. In addition, the fluid nozzle 100 can be connected to air manifolds and nozzle spray tips of different designs.

[0095] FIG. 10A to FIG. 10B A fluid system 1000 is shown that includes a manifold 104 attached to a tube 1002. The tube 1002 may fit in a fluid-tight manner on the mixer 204. The tube 1002 may be similar to the tube 102, except that 1002 may lack a third portion extending from the wall of the second portion 1026.

[0096] For example, tube 1002 may have a first tube end 1006 and a second tube end 1008 opposite first tube end 1006. A fluid passage may extend from an inlet 1010 at first tube end 1006 to an outlet at second tube end 1008. Tube 1002 may have a first portion 1016 and a second portion 1026.

[0097] The first portion 1016 extends from the second portion 1026 toward the second tube end 1008 along the tube axis A1. In some embodiments, the first portion 1016 includes a tapered portion 1018 having a tapered cross-section along the flow direction D1. The tapered portion 1018 can lead to a continuous rib 1024 upstream in the flow direction. In at least one embodiment, the continuous rib 1024 can be arranged on the uniform portion 1020 and protrude from the uniform portion 1020 thereon. The continuous rib 1024 can be configured to grasp the inner surface of the manifold 104, so that the continuous rib 1024 acts as a holding mechanism for the manifold 104. The inner surface of the manifold 104 can also include discontinuous axial ribs arranged along the axis A1 so that the flow of the fluid is laminar.

[0098] The second portion 1026 can extend from the uniform portion 1020 to the first tube end 1006. In some examples, the inner cross-sectional area of ​​the second portion 1026 can be greater than the average cross-sectional area of ​​the first portion 1016. In some embodiments, the second portion can include a wall having a polygonal shape 1028 having a vertex 1036. The second portion 1026 can taper in the flow direction. For example, the (inner) dimension 1038 (e.g., the inner diameter from vertex to vertex in a plane perpendicular to the axis A1) can be greater than dimension 1040. It has been found that tapered and chamfered vertices can result in a more secure interference fit with the mixer tube 206. The tube 1002 can have an inner surface 1042 and an outer surface 1044. In at least one embodiment, the inner surface 1042 can produce a friction or interference fit with the outer dimension of the mixer tube 206. As Fig. 10C As shown, the mixer tube 206 can have an inner surface 209 and an outer surface 207. Dimension 211 can be an outer dimension measured from one vertex on the outer surface 207 to another vertex on the opposite outer surface 207. In some embodiments, dimension 211 can be a diameter. In at least one embodiment, dimension 1040 can be smaller than dimension 211, so that the mixer tube 206 is subjected to slight compression along the periphery. In at least one embodiment, dimension 1038 can be slightly larger than dimension 211. In at least one embodiment, the size of the outer surface 207 can be set relative to the inner surface 1042 so that there is an interference fit between the mixer tube 206 and the tube 1002. For example, an interference of 5 thousandths of an inch (0.127 mm) to 50 thousandths of an inch (1.27 mm).

[0099] In at least one embodiment, the outer surface 1044 of the wall is continuous without protrusions. The cross-sectional shape of the second portion 1026 in a plane perpendicular to the axis A1 is continuous along the second portion. This is different from the tube 102, which has a third portion 130 having a different cross-sectional shape than the segment including the second portion 1026. Such a configuration can be more simplified and reduce material usage.

[0100] FIG. 11A to FIG. 11B A system 1100 is shown that includes a tube 1102 configured to couple to a manifold 104 and a second fluid source 702 (eg, Figure 7 Tube 1102 differs from tube 102 in that tube 1002 may be directly coupled (eg, via threads 1114 ) to second fluid source 702 .

[0101] The tube 1102 may be a single integral component. The tube 1102 includes a first tube end 1106 and a second tube end 1108 opposite to the first tube end 1106. The tube 1102 extends along a tube axis A1 defined between the first tube end 1106 and the second tube end 1108. The tube 1102 includes an inlet 1110 at the first tube end 1106. The fluid F1 may be received in the tube 1102 via the inlet 1110. The tube 1102 also includes an outlet defined at the second tube end 1108. The tube 1102 also includes a fluid passage disposed in the tube 1102 and extending from the inlet 1110 to the outlet. The tube 1102 may also have a thread 1114 integrated into the tube 1102 at the tube end 1106.

[0102] The tube 1102 can have a first portion 1116 and a second portion 1126 (near the threads 1114 or other attachment mechanism). The first portion 1116 can be near the tube end 1108. The first portion 1116 can include a uniform portion 1120 having a continuous rib 1124 for attachment to the manifold 104. The first portion 1116 can also include a tapered portion 1118. In at least one embodiment, the tapered portion 1118 can lead to the continuous rib 1124 upstream in the flow direction. The continuous rib 1124 can also lead to the uniform portion 1120.
