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 connected 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 style or pattern associated with the original manufacturer of the vehicle. When replacing these seam seals, a technician may desire to replicate the style 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 wish to replicate the style 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 were specially designed, conventional fluid nozzles may not be able to replicate the style 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 style 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

[0027] 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.

[0028] In the following disclosure, the following definitions apply.

[0029] 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.

[0030] 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.

[0031] 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).

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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 is less than about 10 weight percent of each of the first and second materials.

[0036] As used herein, “at least one of A and B” should be understood to mean “only A, only B, or both A and B”.

[0037] 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.).

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] Typically, seam sealants are used to seal seams and gaps to prevent leakage (e.g., of water, air, etc.). For example, gaps between various exterior panels of a vehicle (e.g., rear body panels, trunk floor panels, passenger compartment floor panels, frame rails, roof channels / roof trenches, etc.) can be filled with seam sealants to prevent moisture, dust, etc. from passing through these gaps. In downstream repair or aftermarket applications, the gaps between such panels can be resealed by a technician. In some cases, the seam sealants have a unique style or pattern associated with the original manufacturer of the vehicle. In addition, when replacing these seam sealants, technicians may try to replicate the style of the original seam seal or match its quality. However, it may be difficult for technicians to replicate the style of the original seam seal or match its quality.

[0049] In some cases, a wide and / or flat applied seam sealant material may be required to replicate the original seam 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 prior to the seam sealant curing. This may also negatively impact subsequent paint applications.

[0050] Typically, the application of the material of the seam sealant is based on the outlet shape and size of the nozzle designed for dispensing the material of the seam sealant. In addition, in some cases, the material of the seam sealant can be a high viscosity fluid. Some conventional nozzles have an outlet having a wide and / or flat shape for wide and / or flat application of the material of the seam sealant. Such conventional nozzles typically have angled sidewalls that define angled passages for the fluid. The angled passage defined by the angled sidewalls may cause the fluid to continue to flow at the same angle as the angle of the angled sidewalls. Therefore, due to the angled sidewalls of the conventional nozzle, the fluid may extend a considerable distance beyond the desired width. Therefore, such conventional nozzles may not be able to provide controlled application of the fluid / material of the seam sealant. Specifically, conventional nozzles may not be able to provide the desired material width. Therefore, technicians may face difficulties in replicating or matching the original seam sealing.

[0051] Therefore, there is a need for a fluid nozzle that can provide greater control over the application of the seam sealant's material so that a technician can easily replicate or match the original seam seal.

[0052] According to aspects of the present disclosure, a fluid nozzle includes a body including a first end and a second end opposite to the first end. The body extends along a longitudinal axis defined between the first end and the second end. The body includes an outlet disposed at the first end. The outlet has a maximum outlet width orthogonal to the longitudinal axis at the first end. The body also includes an inlet disposed at the second end. The inlet has a maximum inlet width orthogonal to the longitudinal axis at the second end. The maximum outlet width is greater than the maximum inlet width. The body also includes a fluid passage disposed in the body and extending from the inlet to the outlet. The body also includes a pair of side walls, which are opposite to each other and extend from the second end to the first end at least along the longitudinal axis. Each side wall in the pair of side walls includes a plurality of first wall portions and a plurality of second wall portions alternating with each other. Each first wall portion from the plurality of first wall portions is inclined relative to an adjacent second wall portion from the plurality of second wall portions. In addition, each second wall portion in the plurality of second wall portions extends outwardly from the second end to the first end relative to the longitudinal axis in the flow direction, so that the body tapers outwardly in the flow direction. Each first wall portion in the plurality of first wall portions extends parallel to the longitudinal axis. Each of the plurality of second wall portions is inclined at an inclined angle relative to the longitudinal axis.The pair of side walls at least partially defines a fluid passage therebetween.

[0053] Since each of the plurality of first wall portions extends parallel to the longitudinal axis and each of the plurality of second wall portions is inclined at an oblique angle relative to the longitudinal axis, the plurality of first wall portions and the plurality of second wall portions that alternate with each other can allow the fluid flowing through the fluid passage to have more time to be extruded at a desired width. In other words, the plurality of first wall portions and the plurality of second wall portions that alternate with each other can reduce the flow rate of the fluid so that the fluid nozzle can provide a controlled flow of the fluid in the flow direction to achieve the desired width of the fluid and prevent the fluid from extending beyond the desired width. The plurality of first wall portions and the plurality of second wall portions of the fluid nozzle can also limit the fluid to the desired width defined between a pair of side walls to provide a controlled flow of the fluid in the flow direction. Therefore, the fluid may not extend a considerable distance beyond the desired width.

[0054] Thus, the fluid nozzle of the present disclosure that provides controlled flow of the fluid in the flow direction can provide controlled application of a fluid (e.g., a seam sealant) over a gap / seam to achieve a desired appearance (e.g., having a desired width). Specifically, the fluid nozzle can ensure that the fluid is extruded over the gap / seam with a desired width to achieve a desired appearance. Thus, the technician can better control the final appearance of the extruded fluid and improve the ability to replicate or accurately match the original seam seal. In addition, in order to achieve a wide and / or flat appearance, it may not be necessary to machine or brush the applied material, which may otherwise cause air entrapment or contamination prior to curing of the seam sealant and / or adversely affect the coating application at a later time.

[0055] Figure 1 A schematic perspective view of a fluid system 150 according to an embodiment of the present disclosure is shown. The fluid system 150 includes a fluid nozzle 100. The fluid system 150 also includes a fluid source 200 connected to the fluid nozzle 100. In some embodiments, the fluid system 150 may include a fluid line 210 to connect the fluid source 200 to the fluid nozzle 100. In some examples, the fluid nozzle 100 may dispense or extrude a fluid received from the fluid source 200.

[0056] Figure 2 A schematic cross-sectional view of a fluid nozzle 100 is shown according to an embodiment of the present disclosure. Figure 3A A schematic top view of a fluid nozzle 100 is shown according to an embodiment of the present disclosure. Figure 3A A schematic bottom view of a fluid nozzle 100 is shown according to an embodiment of the present disclosure. Figure 4 A schematic front view of a fluid nozzle 100 is shown according to an embodiment of the present disclosure. Figure 5 A schematic side view of a fluid nozzle 100 is shown according to an embodiment of the present disclosure.

[0057] refer to Figures 1 to 5, the fluid nozzle 100 includes a body 110. The body 110 includes a first end 102 and a second end 104 opposite the first end 102. The body 110 extends along a longitudinal axis 101 defined between the first end 102 and the second end 104. In some embodiments, the fluid nozzle 100 also includes a connecting portion 140 disposed at the second end 104 of the body 110. The connecting portion 140 is connected to the fluid source 200.

[0058] In some examples, the fluid nozzle 100 can be made of any suitable material or combination of materials, for example, a polymer material (e.g., injection molded plastic), a metal material, a ceramic material, etc. In addition, the fluid nozzle 100 can be manufactured using any suitable one or more techniques, for example, molding, 3D printing, forging, die casting, machining, stamping, vacuum forming, extrusion, etc. In some examples, the fluid nozzle 100 can be integrally formed as a one-piece component. For example, the body 110 can be integral with the connecting portion 140. In some other examples, the body 110 and the connecting portion 140 can include different materials and / or can be formed as different components.

[0059] The body 110 includes an outlet 106 disposed at the first end 102 and an inlet 108 disposed at the second end 104 (at Figure 3B The body 110 also includes a fluid passage 111 disposed within the body 110 and extending from the inlet 108 to the outlet 106 (best shown in FIG. Figure 2 1 ). The outlet 106 includes a maximum outlet width 107 orthogonal to the longitudinal axis 101 at the first end 102. In addition, the inlet 108 includes a maximum inlet width 117 orthogonal to the longitudinal axis 101 at the second end 104. The maximum outlet width 107 is greater than the maximum inlet width 117. In some embodiments, the maximum outlet width 107 is at least 2 times greater than the maximum inlet width 117. In some embodiments, the maximum outlet width 107 is at least 2 times, at least 2.5 times, at least 3 times, at least 3.5 times, at least 4 times, at least 4.5 times, or at least 5 times greater than the maximum inlet width 117.

[0060] The body 110 further includes a pair of side walls 120 that are opposite to each other and extend from the second end 104 to the first end 102 along at least the longitudinal axis 101. Each side wall of the pair of side walls 120 includes a plurality of first wall portions 122 and a plurality of second wall portions 124 that alternate with each other.

[0061] Each first wall portion 122 from the plurality of first wall portions 122 is inclined relative to an adjacent second wall portion 124 from the plurality of second wall portions 124. Each second wall portion of the plurality of second wall portions 124 extends outwardly from the second end 104 to the first end 102 in the flow direction 112 relative to the longitudinal axis 101 such that the body 110 tapers outwardly in the flow direction 112. The pair of sidewalls 120 at least partially defines a fluid passage 111 therebetween.

[0062] In the illustrated embodiment, each of the pair of side walls 120 includes five first wall portions 122 alternating with four second wall portions 124. However, the number of first wall portions 122 and the number of second wall portions 124 may vary based on application properties. In addition, in the illustrated embodiment, the first wall portions 122 have the same size and the second wall portions 126 have the same size. However, in some alternative embodiments, at least two first wall portions 122 may have different sizes and at least two second wall portions 126 may have different sizes.

[0063] Each of the plurality of first wall portions 122 extends parallel to the longitudinal axis 101. In addition, each of the plurality of second wall portions 124 is inclined at an angle of inclination 126 relative to the longitudinal axis 101. In some embodiments, the angle of inclination 126 is between about 30 degrees and about 90 degrees. In some embodiments, the angle of inclination 126 is about 40 degrees, about 45 degrees, about 50 degrees, about 55 degrees, about 60 degrees, or about 65 degrees. In the illustrated embodiment, the angle of inclination 126 is the same for the plurality of second wall portions 124. However, in some other embodiments, at least two second wall portions 124 may have angles of inclination 126 of different values.

[0064] Each of the plurality of first wall portions 122 extending parallel to the longitudinal axis 101 and each of the plurality of second wall portions 124 inclined at the inclination angle 126 relative to the longitudinal axis 101 can allow the fluid flowing through the fluid passage 111 more time to be extruded at a desired width. In other words, the plurality of first wall portions 122 and the plurality of second wall portions 124 of the fluid nozzle 100 can reduce the flow rate of the fluid so that the fluid nozzle 100 can provide a controlled flow of the fluid in the flow direction 112 to achieve a desired width of the fluid and prevent the fluid from extending beyond the desired width. The plurality of first wall portions 122 and the plurality of second wall portions 124 of the fluid nozzle 100 can also confine the fluid to a desired width defined between the pair of sidewalls 120 to provide a controlled flow of the fluid in the flow direction 112. This can prevent the extruded fluid from extending a considerable distance beyond the desired width and thus allow controlled application of the fluid to achieve a desired appearance for replicating or precisely matching the original seam seal.

[0065] In some embodiments, the plurality of first wall portions 122 include a proximal first wall portion 122A extending from the first end 102 and a distal first wall portion 122B extending from the second end 104. Figures 1 to 5 In the illustrated embodiment of the present invention, the proximal first wall portion 122A defines the outlet 106 of the body 110, and the distal first wall portion 122B defines the inlet 108 of the body 110 and is connected to the connecting portion 140 disposed at the second end 104 of the body 110. In some embodiments, the connecting portion 140 is in fluid communication with the inlet 108 of the body 110 and surrounds the inlet. Specifically, the connecting portion 140 is hollow and defines a connecting channel 141 therein (in Figure 3B 108 of the main body 110. The connecting channel 141 has a larger size than the inlet 108. In some embodiments, the proximal first wall portion 122A defining the outlet 106 of the main body 110 can be based on application properties, such as the desired width of the fluid for replicating or accurately matching the original seam seal. Therefore, the fluid nozzle 100 includes a pair of proximal first wall portions 122A corresponding to the pair of side walls 120 and a pair of distal wall portions 122B.

[0066] In some embodiments, the body 110 further includes a pair of longitudinal walls 130 that are opposite to each other and extend from the second end 104 to the first end 102. In addition, each longitudinal wall of the pair of longitudinal walls 130 extends between the pair of side walls 120. The pair of longitudinal walls 130 and the pair of side walls 120 can define a fluid passage 111 therebetween.

[0067] exist Figures 1 to 5 In the illustrated embodiment, each longitudinal wall of the pair of longitudinal walls 130 is planar. In addition, each side wall of the pair of side walls 120 has a rectangular cross-section. Therefore, in some embodiments, the fluid passage 111 in the body 110 has a rectangular cross-section. The rectangular cross-section of the fluid passage 111 can help the controlled flow of the fluid in the flow direction 112 to achieve a desired appearance.

[0068] Additionally, in some embodiments, each of the pair of sidewalls 120 defines a thickness 128 of the body 110 orthogonal to the longitudinal axis 101. In some embodiments, the thickness 128 is constant along the length 118 of the body 110. Thus, in some embodiments, the outlet 106 also has a rectangular cross-section.

[0069] In some embodiments, the body 110 defines a width axis 103 that is perpendicular to the longitudinal axis 101 and a thickness axis 105 that is orthogonal to each of the width axis 103 and the longitudinal axis 101. In some embodiments, the body 110 is disposed relative to a first plane 113 (e.g., Figure 2 ) and a second plane 115 (as shown) including the longitudinal axis 101 and the thickness axis 105 Figure 1 Since the body 110 is symmetrical with respect to each of the first plane 113 and the second plane 115, the fluid can have a symmetrical flow in the fluid passage 111, which can ensure that the extruded fluid has a desired appearance (i.e., has a desired width).

[0070] In some embodiments, the body 110 has a maximum width 114 at the first end 102 that is orthogonal to the longitudinal axis 101, and has a minimum width 116 at the second end 104 that is orthogonal to the longitudinal axis 101. Specifically, the body 110 has a maximum width 114 along the width axis 103 at the first end 102, and has a minimum width 116 along the width axis 103 at the second end 104. In some embodiments, the maximum width 114 is at least 2 times greater than the minimum width 116. In some embodiments, the maximum width 114 is at least 2.5 times, at least 3 times, at least 3.5 times, at least 4 times, at least 4.5 times, or at least 5 times greater than the minimum width 116. Thus, the fluid nozzle 100 can provide a wide application of the fluid to replicate an original seal with a wide appearance.

[0071] In some embodiments, the outlet 106 includes a maximum outlet thickness 109 orthogonal to each of the maximum outlet width 107 and the longitudinal axis 101. Specifically, the outlet 106 includes a maximum outlet width 107 along the width axis 103 and a maximum outlet thickness 109 along the thickness axis 105. In some embodiments, the maximum outlet width 107 is at least 5 times greater than the maximum outlet thickness 109. In some embodiments, the maximum outlet width 107 is at least 5.5 times, at least 6 times, at least 6.5 times, at least 7 times, at least 7.5 times, at least 8 times, at least 8.5 times, at least 9 times, at least 9.5 times, or at least 10 times greater than the maximum outlet thickness 109. Thus, the fluid nozzle 100 can provide a flat application of the fluid to replicate an original seal with a flat appearance.

[0072] As mentioned above, Figure 1The fluid system 150 shown includes a fluid source 200 connected to the fluid nozzle 100. Specifically, the fluid source 200 is arranged to be in fluid communication with the fluid passage 111. In addition, the connection portion 140 is connected to the fluid source 200. The fluid nozzle 100 can dispense the fluid received from the fluid source 200. Specifically, the outlet 106 of the fluid nozzle 100 can dispense the fluid received from the fluid source 200. In some examples, the fluid source 200 can be connected to the fluid nozzle 100 through a fluid pipeline 210. The fluid pipeline 210 can guide the fluid from the fluid source 200 to the fluid nozzle 100. Specifically, the fluid pipeline 210 can guide the fluid from the fluid source 200 to the inlet 108 of the fluid nozzle 100. In some embodiments, the fluid nozzle 100 is connected to the fluid pipeline 210 via the connection portion 140.

[0073] exist Figure 1 In the illustrated embodiment of the present invention, the connecting portion 140 includes a square cross-section. However, the connecting portion 140 can have any suitable shape and size based on the application requirements. For example, the shape and size of the connecting portion 140 can be based on the shape and size of the fluid line 210. In some embodiments, the connecting portion 140 can have a polygonal or circular cross-section in a plane orthogonal to each of the first plane 113 and the second plane 115.

[0074] In some examples, the fluid source 200 can be directly connected to the fluid nozzle 100 (e.g., by threaded engagement, press fit, quarter-turn locking mechanism, etc.) without the need for a fluid line 210. In some examples, the fluid source 200 can include any suitable one or more fluid sources. In some examples, the fluid source 200 can include an associated plunger (not shown). In some examples, the plunger can be used to force the fluid (e.g., by applying pressure) through the fluid nozzle 100, thereby forcing the fluid through the outlet 106. In some examples, the fluid source 200 can include one or more chambers that can store one or more components of the fluid to be dispensed through the fluid nozzle 100.

[0075] In some examples, the fluid source 200 may include two chambers for storing two components. In some examples, the components from the respective chambers may be mixed prior to being dispensed through the fluid nozzle 100. For example, a mixer (not shown) disposed between the fluid source 200 and the fluid nozzle 100 may mix the components together prior to directing the mixture of the components into the inlet 108 of the fluid nozzle 100.

[0076] In some examples, the fluid from the fluid source 200 may include any suitable material or combination of materials, such as a seam sealant, epoxy, foam, adhesive (e.g., a one-component or two-component adhesive), filler, etc. 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 sealants, one-component and two-component acrylic sealants, wet-on one-component and two-component moisture-proof sealants, UV-curable sealants, blue light-curable sealants, heat-activated sealants, etc. In addition, any suitable adhesive may be used, such as one-component and two-component acrylic adhesives, etc. In some examples, the fluid may be a seam sealing composition suitable for sealing one or more seams disposed between panels of a vehicle or a boat, or sealing seams present on an interior or exterior surface of a building.

The fluid nozzle 160 is substantially similar to Figures 1 to 5 The fluid nozzle 100 is shown. However, the fluid nozzle 160 has an outlet 166 instead of the outlet 106 (eg, Figure 3A Specifically, the outlet 166 of the fluid nozzle 160 has an elliptical cross-section.

Figures 1 to 6 At step 302, the method 300 includes connecting the fluid nozzle 100, 160 to the fluid source 200. At step 304, the method 300 includes directing the fluid from the fluid source 200 into the inlet 108 of the fluid nozzle 100, 160. At step 306, the method 300 includes ejecting the fluid through the outlet 106, 166 of the fluid nozzle 100, the fluid nozzle 160.
