Abstract

The fluid nozzle includes a tube including a first tube end and a second tube end opposite the first tube end. The tube extends along a tube axis defined between a first tube end and a second tube end. The tube defines a first axis orthogonal to the tube axis and a second axis orthogonal to each of the tube axis and the first axis. The outlet is symmetrical with respect to each of the first axis and the second axis. The fluid nozzle also includes only one guide member extending from only one side of the tube along the first axis and aligned with an outlet width of the outlet. A portion of the only one guide member further extends beyond the first tube end along the tube axis.

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 "attached," "connected," "coupled" 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] According to aspects of the present disclosure, a fluid nozzle includes a 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 defines a first axis orthogonal to the tube axis and a second axis orthogonal to each of the tube axis and the first axis. The tube also includes an outlet disposed at the second tube end. The outlet includes a first outlet end, a second outlet end opposite to the first outlet end, an outlet width between the first outlet end and the second outlet end along the first axis, and an outlet height along the second axis. The outlet is symmetrical with respect to each of the first axis and the second axis. The tube also includes an inlet disposed 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 fluid nozzle also includes only one guide member extending from only one side of the tube along the first axis and aligned with the outlet width of the outlet. Only a portion of one guide member further extends beyond the first tube end along the tube axis.

[0049] The fluid nozzle includes only one guide member extending from only one side of the tube along the first axis. The only one guide member allows the fluid nozzle to align with the edge of the component to which the fluid can be applied and to follow the edge while the fluid is extruded onto the component. Therefore, only one guide member can guide the fluid nozzle when the fluid is extruded onto the component. Conventional fluid nozzle designs have dual guide members, wherein the guide members extend from opposite sides of the tube. One of the guide members needs to be cut off before use. However, in the present disclosure, only one guide member extends from only one side of the tube.

[0050] In addition, the outlet is symmetrical with respect to each of the first axis and the second axis, thereby allowing the same cross-sectional profile of the outlet, regardless of whether the fluid nozzle is used by the user in a left-handed orientation or a right-handed orientation. Therefore, the fluid nozzle of the present disclosure can reduce errors in fluid application by providing a consistent cross-section for the outlet, regardless of the orientation of the fluid nozzle in which the user applies the fluid. This is also possible because only one guide member is provided on only one side of the tube. In addition, the outlet can allow a consistent profile of the fluid to be extruded onto the component. The symmetrical cross-section of the outlet combined with only one guide member can allow the time required for fluid application to be reduced and the quality of the seal to be improved by following the edge of the component.

[0051] Now referring to the accompanying drawings, Figure 1 1 shows a schematic diagram of an example of a fluid system 100 including a fluid nozzle 102, a static mixing nozzle 174, and a fluid source 116. Specifically, Figure 1 1 shows a schematic front exploded perspective view of the fluid nozzle 102 and the static mixing nozzle 174. Figure 1 Schematically shown in FIG. 1 is a fluid source 116. The fluid nozzle 102 includes a tube 104 including a first tube end 106 and a second tube end 108 opposite to the first tube end 106. The tube 104 extends along a tube axis XX' defined between the first tube end 106 and the second tube end 108. The tube 104 also includes an inlet 110 disposed at the first tube end 106. The outlet 110 includes a first outlet end 120 and a second outlet end 122 opposite to the first outlet end 120.

[0052] In some examples, tube 104 can be made of any suitable material or combination of materials, such as polymeric materials (e.g., injection molded plastics), metallic materials, ceramic materials, etc. In addition, tube 104 can be manufactured using any suitable one or more techniques, such as molding, 3D printing, forging, die casting, machining, stamping, vacuum forming, extrusion, etc. In some examples, tube 104 can be integrally formed as a one-piece component.

[0053] The fluid system 100 also includes a fluid source 116 connected to the fluid nozzle 102. In some examples, the fluid nozzle 102 can dispense fluid received from the fluid source 116. In some examples, the fluid source 116 may include any suitable one or more fluid sources. In some examples, the fluid source 116 may 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 102, thereby forcing the fluid through the outlet 110. In some examples, the fluid source 116 may include one or more chambers that can store one or more components of the fluid to be dispensed through the fluid nozzle 102.

[0054] In some examples, the fluid source 116 can include two chambers for storing fluid components. In some examples, the fluid components from the various chambers can be mixed prior to being dispensed through the fluid nozzle 102. For example, a static mixer or a dynamic mixer can be disposed between the fluid source 116 and the fluid nozzle 102, and can mix the fluid components together prior to directing the mixture into the fluid nozzle 102.

[0055] exist Figure 1 In the illustrated embodiment of the present invention, the fluid system 100 also includes a static mixing nozzle 174 (i.e., a static mixer) that is configured to be coupled to the fluid source 116 and the fluid nozzle 102. Therefore, the fluid source 116 is indirectly coupled to the fluid nozzle 102 through the static mixing nozzle 174. Alternatively, in some other examples, the fluid source 116 may be directly coupled to the fluid nozzle 102 (e.g., by threaded engagement, press fit, quarter-turn locking mechanism, etc.) without the need for a static mixing nozzle 174. It should be understood that the static mixing nozzle 174 is not necessarily coupled to the fluid source 116. Figure 1 1 is shown by way of example only, and fluid system 100 may include any type of mixer.

[0056] In some examples, the static mixing nozzle 174 has a first shape profile 176. In some examples, the fluid nozzle 102 has a second shape profile 178 (also referred to as a second shape profile 178) that is complementary to the first shape profile 176. Figure 2 ), so that the static mixing nozzle 174 can be matched with the fluid nozzle 102. Specifically, the second tube end 108 of the fluid nozzle 102 has a second shape profile 178 that is complementary to the first shape profile 176 of the static mixing nozzle 174, so that the second tube end 108 is matched with the first shape profile 176 of the static mixing nozzle 174. For example, the second tube end 108 is shown to have a square profile (also shown as Figure 2 ) to mate with the square profile of the static mixing nozzle 174.

[0057] In some examples, the fluid from fluid source 116 may include any suitable material or combination of materials, such as seam sealants, epoxies, foams, adhesives (e.g., one-component or two-component adhesives), fillers, and the like. It should be appreciated that 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-in-wet one-component and two-component moisture resistant sealants, UV-curable sealants, blue light-curable sealants, heat-activated sealants, and the like. Additionally, any suitable adhesive may be used, such as one-component and two-component acrylic adhesives, and the like. In some examples, the fluid may be a high viscosity fluid (or other seam sealing composition) suitable for sealing one or more seams disposed between panels of a vehicle, or for sealing seams present on an interior or exterior surface of a building.

[0058] Figure 2 A schematic rear perspective view of the fluid nozzle 102 is shown. Figure 1 and Figure 2 The tube 104 also includes an inlet 112 (eg, Figure 2 In some examples, the fluid source 116 (eg, Figure 1 104 is fluidly coupled to an inlet 112 of the tube 104. The tube 104 also includes a Figure 2 ) extends to the outlet 110 (as shown) Figure 1 In some examples, a fluid source 116 (such as Figure 1 ) is configured to be fluidically connected to the fluid passage 114.

[0059] In some examples, the fluid passage 114 disposed within the tube 104 may have any suitable shape and may have any suitable size based on application requirements. In some examples, the fluid passage 114 may have a polygonal cross-section in a plane orthogonal to the tube axis XX'. In addition, in some examples, a portion of the fluid passage 114 has a constant cross-sectional area when measured in a plane orthogonal to the tube axis XX'. In some examples, a portion of the fluid passage 114 has a varying cross-sectional area in a plane orthogonal to the tube axis XX'.

[0060] In some examples, the tube 104 further includes a tube extending along the tube axis XX′ and including a first tube end 106 and an outlet 110 (eg, Figure 1 In some examples, the first tube portion 124 tapers from the second tube end 108 to the first tube end 106 along the flow direction F. In some examples, the first tube portion 124 at least partially defines a fluid passage 114 therethrough.

[0061] In some examples, the first tube portion 124 includes a first tapered wall 126 disposed proximal to the first outlet end 120 and tapering inwardly relative to the tube axis XX' along the flow direction F, a second tapered wall 128 opposite to the first tapered wall 126 and tapering inwardly relative to the tube axis XX' along the flow direction F, and a pair of side walls 130. In some examples, each of the pair of side walls 130 extends between the first tapered wall 126 and the second tapered wall 128. In some examples, each of the first tapered wall 126 and the second tapered wall 128 is curved. In some examples, each of the pair of side walls 130 is planar. However, based on application requirements, the first tapered wall 126, the second tapered wall 128, and each of the pair of side walls 130 may have any other shape.

[0062] In some examples, the tube 104 further includes a second tube end 108 and an inlet 112 (eg, Figure 2 In some examples, the second tube portion 132 includes a polygonal shape along a length L of the second tube portion 132. In some examples, the second tube portion 132 at least partially defines a fluid passage 114 therethrough.

[0063] In some examples, the tube 104 also includes a third tube portion 134 disposed between the first tube portion 124 and the second tube portion 132 and at least partially defining the fluid passage 114 therethrough. In some examples, the third tube portion 134 includes a pair of curved walls 136 that are opposite to each other. In some examples, each of the pair of curved walls 136 tapers from the second tube portion 132 toward the first tube portion 124. In some examples, the third tube portion 134 also includes a pair of planar walls 138 that are opposite to each other along the pair of curved walls 136 and extend between the pair of curved walls.

[0064] The fluid nozzle 102 also includes only one guide member 140 extending from only one side 141 of the tube 104. In other words, only one guide member 140 is disposed on only one side (i.e., side 141) of the tube 104 and on the tube axis XX'. In some examples, the first tapered wall 126 defines only one side 141 of the tube 104. The other side of the tube 104, which is at least partially defined by the second tapered wall 128, does not include any guide member. In some examples, only one guide member 140 is connected to the first tapered wall 126. In addition, only a portion 143 of one guide member 140 extends beyond the first tube end 106 along the tube axis XX'. In some examples, the fluid nozzle 102 includes only a single guide member 140. In other words, the fluid nozzle 102 includes no more than one guide member 140.

[0065] In some examples, the second tapered wall 128 is smooth. As used herein, the term "smooth" generally refers to a uniform or regular or consistent surface, i.e., without any perceptible protrusions, lumps, or depressions. The term may also mean that there are no protrusions, such as those caused by tearing, cutting, or otherwise removing a guide member, which may be integrally formed or otherwise attached to the tapered wall. In other words, the second tapered wall 128 may not include any jagged portions, for example, a tear from one of the guide members, as in the case of a conventional fluid nozzle design with dual guide members.

[0066] Figure 3 A schematic front view of the fluid nozzle 102 is shown. In some examples, only one guide member 140 includes a bottom edge 142 extending from the tube 104 toward the first tube end 106 and obliquely inclined relative to the tube axis XX', a first side edge 144 extending from the bottom edge 142 along the tube axis XX' beyond the first tube end 106, a top edge 146 extending from the first side edge 144, a second side edge 148 extending from the top edge 146 along the tube axis XX' to the tube 104, and a coupling portion 150 connected to and coupled to the tube 104. In some examples, the top edge 146 is spaced apart from the first tube end 106 relative to the tube axis XX'.

[0067] In some examples, the coupling portion 150 extends between the second side edge 148 and the bottom edge 142. In some examples, only one guide member 140 is coupled to the tube 104 via the coupling portion 150. In some examples, only one guide member 140 is integrally formed with the tube 104. In some examples, only one guide member 140 may have the same material as the tube 104.

[0068] In some examples, only one guide member 140 also includes a first rounded interface 152 disposed between the bottom edge 142 and the first side edge 144 , a second rounded interface 154 disposed between the first side edge 144 and the top edge 146 , and a third rounded interface 156 disposed between the top edge 146 and the second side edge 148 .

[0069] In some examples, only the second side edge 148 of one guide member 140 may be in contact with the fluid of the component from the fluid source 116 (eg, Figure 1 143) by the edge to which the fluid nozzle 102 is applied. Thus, only one guide member 140 may allow the fluid nozzle 102 to follow the edge of the component, such as through portion 143, thereby guiding the fluid nozzle 102 as the fluid is applied to the component. This may facilitate directing the fluid from the fluid source 116 (such as Figure 1 as shown) is applied to the component.

[0070] Figure 4 A schematic top view of the fluid nozzle 102 is shown. In some examples, the tube 104 defines a first axis AA' orthogonal to the tube axis XX' and a second axis BB' orthogonal to each of the tube axis XX' and the first axis AA'.

[0071] In some examples, a pair of side walls 130 (eg, Figures 1 to 3 In some examples, a pair of curved walls 136 (as shown in FIG. 1 ) of the third tube portion 134 are opposite to each other along the second axis BB′. Figures 1 to 3 In some examples, a pair of planar walls 138 (such as Figures 1 to 3 As shown) are opposite to each other along the first axis AA'.

[0072] In some examples, the outlet 110 also includes an outlet width 160 along the first axis A-A' between the first outlet end 120 and the second outlet end 122 and an outlet height 162 along the second axis BB'. In some examples, the outlet width 160 is about 2 times to about 10 times the outlet height 162. In some examples, only one guide member 140 extends from the tube 104 along the first axis A-A' and is aligned with the outlet width 160 of the outlet 110. In some examples, the top edge 146 of only one guide member 140 extends along the first axis A-A'. In some examples, only one guide member 140 has a constant thickness T along the second axis BB'.

[0073] In some examples, the outlet 110 also includes a first longitudinal edge 164 extending along the first axis A-A', a second longitudinal edge 166 spaced apart from the first longitudinal edge 164 relative to the second axis BB' and extending along the first axis A-A', a first curved edge 168 disposed at the first outlet end 122 and extending between the first longitudinal edge 164 and the second longitudinal edge 166, and a second curved edge 172 disposed at the second outlet end 120 and extending between the first longitudinal edge 164 and the second longitudinal edge 166. In some examples, the outlet 110 is symmetrical relative to each of the first axis A-A' and the second axis BB'. Therefore, the fluid nozzle 102 (including only one guide member 140) can be used by the user in a right-hand orientation and a left-hand orientation. This is also possible because only one guide member 140 is disposed on only one side 141 of the tube 104.

[0074] Figure 5 is a flow chart showing a method 200 of using the fluid nozzle 102. Figures 1 to 4 and FIG. 6A to FIG. 6DThe method 200 is described with reference to the fluid nozzle 102 .

[0075] Fig. 6A A schematic side view of the fluid nozzle 102 and the fluid source 116 is shown. Fig. 6A For the purpose of illustration, Figure 1 The fluid source 116 is schematically shown in FIG. Figure 5 and Fig. 6A At step 202, method 200 includes connecting fluid nozzle 102 to fluid source 116. In some examples, fluid nozzle 102 may be coupled to fluid source 116 via a threaded engagement. It should be appreciated that any suitable coupling mechanism may be utilized to couple fluid nozzle 102 to fluid source 116.

[0076] Figure 6B A schematic perspective view of the fluid nozzle 102, the fluid source 116, and the component 210 is shown. Referring now to Figure 5 and Figure 6B At step 204 , the method 200 further includes engaging only one guide member 140 with the edge 212 of the component 210 . Specifically, only the second side edge 148 of the one guide member 140 is configured to engage with the edge 212 of the component 210 .

[0077] Figure 6C A schematic perspective view of the fluid nozzle 102, the fluid source 116, and the component 210 is shown, wherein the fluid 214 is directed from the fluid source 116 into the fluid nozzle 102. Referring now to Figure 5 and Figure 6C At step 206, the method 200 further includes directing a fluid 214 from the fluid source 116 to the inlet 112 of the tube 104 of the fluid nozzle 102 (eg, Figure 2 shown).

[0078] Fig.6D A schematic perspective view of a fluid nozzle 102, a fluid source 116, and a component 210 is shown, wherein a fluid 214 is ejected through the fluid nozzle 102. Referring now to Figure 5 and Fig.6D At step 208, the method 200 further includes passing the outlet 110 (eg, Figure 1 and Figure 4 ) while ejecting fluid 214 while moving the fluid nozzle 102 along the edge 212 of the component 210, as indicated by arrow 216.

[0079] Reference now Figures 1 to 6D, the fluid nozzle 102 includes only one guide member 140 extending from only one side 141 of the tube 104 along the first axis AA'. Only one guide member 140 can allow the fluid nozzle 102 to be aligned with the edge 212 of the component 210, to which the fluid 214 can be applied and follow the edge 212 while the fluid 214 is extruded onto the component 210. Therefore, when the fluid 214 is extruded onto the component 210, only one guide member 140 can guide the fluid nozzle 102.

[0080] In addition, the outlet 110 is symmetrical with respect to each of the first axis A-A' and the second axis BB', thereby allowing the same cross-sectional profile of the outlet 110, regardless of whether the fluid nozzle 102 is used by the user in a left-handed orientation or a right-handed orientation. Therefore, the fluid nozzle 102 of the present disclosure can reduce errors in the application of the fluid 214 by providing a consistent cross-section for the outlet 110, regardless of the orientation of the fluid nozzle 102 in which the user applies the fluid 214. This is also possible because only one guide member 140 is provided on only one side 141 of the tube 104. In addition, the outlet 110 can allow a consistent profile of the fluid 214 to be extruded onto the component 210. The symmetrical cross-section of the outlet 110 combined with only one guide member 140 can allow the time required for the application of the fluid 214 to be shortened and the sealing quality to be improved by following the edge 212 of the component 210.
