Description

BACKGROUND

[0001] Sensors such as pH sensors, dissolved oxygen sensors, capacitance sensors, conductivity sensors, and redox potential sensors are used in various fields to measure and detect certain conditions in vessels, pipes, flow-through chambers, and the like. For example, the fields of chemistry, biotechnology, pharmaceuticals, food and beverage, and the like often require the use of one or more sensors during production or quality control testing.

[0002] While many applications in these and other industries have begun to transition to disposable products, sensors are often still configured to be reusable. However, many sensors have proven difficult to clean due to the inclusion of sensitive electrical components in the sensor, outside of clean-in-place (CIP) applications. As a result, many sensors, while configured to be reused, are disposed of after each use due to concerns of product carryover and cleanability. This problem is further exacerbated by the fact that manual cleaning is often inefficient, ineffective, or requires expensive and time-consuming equipment.

[0003] Accordingly, it would be beneficial to provide a solution to one or more of the aforementioned problems. For example, it would be beneficial to provide a liquid-tight assembly for protecting the electrical components of a component to be cleaned, such as a sensor, that leaves the remainder of the component exposed. It would be a further improvement to provide a liquid-tight assembly that can be used with many or most existing sensors. Additionally, it would be beneficial in an aspect to provide an assembly that protects the electrical components of a component and that is also shaped and sized to be compatible with standard parts washers, such as automated parts washers. A further improvement would be to provide an assembly that is removably secured to the component while remaining liquid-tight. SUMMARY

[0004] The present disclosure generally relates to a sealing assembly for providing a liquid-tight seal around a component during cleaning. In an aspect, the sealing assembly includes an end cap, a sleeve, a sealing gasket, and a sealing clamp. The end cap has a first end and a second end, where the first end includes an opening and the second end is completely closed, and a cavity extends from the opening toward the second end. The sealing assembly also includes a sleeve having a first end and a second end, where the sleeve includes an opening in the first end and an opening in the second end, and defines a cavity therebetween. Further, the cavity in the end cap and the cavity defined by the sleeve are aligned and configured to receive the component therein.

[0005] In another aspect, the end cap, the sleeve, or both the end cap and the sleeve include a base having a groove extending circumferentially around the base of the respective sleeve or end cap. Further, in an aspect, the end cap, the sleeve, or both the end cap and the sleeve include a protrusion extending from the base to the second end of the respective sleeve or end cap. Further, in an aspect, the base of the sleeve, the end cap, or both the end cap and the sleeve has a diameter that is about 1.5 times or more the inner diameter of the protrusion of the respective end cap or sleeve. In an aspect, the protrusion of the sleeve, the end cap, or both the end cap and the sleeve has an inner diameter of about 15 mm or more. Further, in an aspect, the base of the sleeve, the end cap, or both the end cap and the sleeve has a diameter of about 35 mm or more. In another aspect, the protrusion of the end cap has a length from the first end to the second end of about 25 mm to about 75 mm. Further, in an aspect, the protrusion of the sleeve has a length between the first end and the second end of about 1 mm to about 25 mm.

[0006] Additionally or alternatively, in an aspect, the gasket includes a ridge extending circumferentially around the gasket. In an aspect, the ridge is located in the groove of the end cap, the sleeve, or both the end cap and the sleeve.

[0007] In yet another aspect, the sealing assembly further includes a retainer. In an aspect, the retainer includes one or more holes having a diameter of about 17.5 mm to about 45 mm.

[0008] The present disclosure can also generally relate to an apparatus for cleaning a sensor containing electrical components. The apparatus includes a sealing assembly and a retainer. The sealing assembly contains an end cap, a sleeve, a sealing gasket, and a sealing clamp. The end cap includes a first end and a second end, where the first end has an opening and the second end is completely closed, where a cavity extends from the opening to the second end. The sleeve has a first end and a second end, where the sleeve includes an opening in the first end and an opening in the second end, and defines a cavity therebetween. Further, the cavity in the end cap and the cavity defined by the sleeve are aligned and configured to receive the components therein.

[0009] In an aspect, the retainer of the apparatus includes one or more holes having a diameter of about 17.5 mm to about 45 mm. Further, in an aspect, the end cap has a protrusion having an outer diameter of about 17.5 mm to about 45 mm. In another aspect, the end cap is releasably held in the hole of the retainer.

[0010] Nevertheless, this disclosure also relates generally to a method for cleaning components requiring a liquid-tight seal. The method includes: assembling a sealing assembly onto a component by placing a component through a cavity in a sleeve having a first end and a second end, wherein the sleeve includes an opening in the first end and an opening in the second end, and a cavity defined therebetween; placing a sealing gasket onto the component; placing the distal end of the component into a cavity in an end cap having a first end and a second end, wherein the first end includes an opening and the second end is completely closed, and wherein the cavity extends from the opening to the second end; and placing a clamp around the sleeve, the sealing gasket, and the end cap.

[0011] Additionally or alternatively, on one hand, the end cap is releasably retained in the hole of the retainer. Furthermore, on another hand, the retainer holds the component in a generally horizontal position. Still on yet another hand, after assembling the sealing assembly, the component is placed into the automatic washer.

[0039] Definitions

[0040] It should be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. In this specification and the following claims, numerous terms will be used, which will be defined as having the following meanings:

[0041] As used herein, the terms “about,” “approximately,” or “roughly”, when used to modify a value, indicate that the value may be increased or decreased by 10% and remain within the disclosed embodiments. Detailed Implementation

[0042] Those skilled in the art will understand that this discussion is merely a description of exemplary embodiments and is not intended to limit the broader aspects of this disclosure.

[0043] Generally, this disclosure relates to sealing assemblies comprising an end cap having a fully closed end, a sleeve, a sealing gasket, and a sealing clamp. Furthermore, in another aspect, the invention may also generally relate to a sealing assembly and a retainer configured to releasably receive at least a portion of the end cap, wherein the retainer is configured to hold the component and the sealing assembly in a generally horizontal position, such as in an automated parts washer during a cleaning cycle. Additionally, this disclosure may also generally relate to methods for cleaning components such as sensors. For example, placing a sleeve on the component with its base end facing the distal end of the component, placing a sealing gasket between the sleeve and the distal end of the component, and placing an end cap on the distal end of the component with its base facing the base of the sleeve. In particular, this disclosure has found that by carefully configuring the sealing assembly according to this disclosure, a sealing assembly for sensors can be formed that is sized to fit many or most of the components while still remaining liquid-tight.

[0044] For example, in one aspect, the sealing assembly includes an end cap having a base and a protrusion. The protrusion includes a first end having an opening and a fully closed second end, wherein a cavity extends from the opening toward the second end. In another aspect, the base is configured to mate with a base of a sleeve or a sealing gasket, or both, to provide a liquid-tight seal around a distal end of a component such as a sensor (e.g., an end of a component remote from the measuring end, or an end where an electrical component to be protected is located). For example, the end cap may be shaped and sized to have an open end and a fully closed end, thereby being releasably disposed on the distal end of the component.

[0045] Furthermore, on one hand, the protruding portion of the end cap can have a generally cylindrical shape, with one end closed and the other end (i.e., the opposite end) connected to the base. Of course, it should be understood that the end cap can also have various cross-sections, such as square, elliptical, rectangular, etc., and on one hand, can have a cross-section selected based on the cross-section of the sensor or component to be covered. Generally, the base can have the same cross-section as the protruding portion, but not necessarily the same diameter or width; however, on the other hand, the base and the protruding portion can be chosen to have different cross-sections.

[0046] Regardless of the cross-section chosen, on one hand, the diameter (or width, if a non-circular cross-section is used) of the base can typically be about 1.5 times or more the inner diameter of the protrusion, such as about 2 times or more the inner diameter of the protrusion, such as about 2.3 times or more the inner diameter of the protrusion.

[0047] Regardless of the diameter ratio, on one hand, the protrusion may have an inner diameter (or width) of about 15 mm or greater, such as about 17.5 mm or greater, such as about 20 mm or greater, such as about 22 mm or greater, such as about 40 mm or less, such as about 35 mm or less, such as about 32.5 mm or less, such as about 30 mm or less, such as about 27.5 mm or less, or any range or value therein, and on another hand, may have an inner diameter of about 20 mm to about 25 mm.

[0048] In addition, the protrusion may have an outer diameter of about 17.5 mm or greater, such as about 20 mm or greater, such as about 22 mm or greater, such as about 25 mm or greater, such as about 30 mm or greater, such as about 45 mm or less, such as about 40 mm or less, such as about 35 mm or less, such as about 32.5 mm or less, such as about 30 mm or less, such as about 27.5 mm or less, such as about 25 mm or less, or any range or value therein, and in one aspect, may have an outer diameter of about 20 mm to about 30 mm.

[0049] On one hand, the base may have a diameter of about 35 mm or greater, such as about 40 mm or greater, such as about 45 mm or greater, such as about 50 mm or greater, such as about 70 mm or less, such as about 65 mm or less, such as about 60 mm or less, such as about 55 mm or less, or any range or value therein, and on the other hand, may have a diameter of about 45 mm to about 55 mm.

[0050] Regardless of the chosen cross-section and diameter, on one hand, the length of the protruding portion from the first end adjacent to the base to the fully enclosed second end can be about 25 mm or more, such as about 30 mm or more, such as about 35 mm or more, such as about 40 mm or more, such as about 42.5 mm or more, such as about 75 mm or less, such as about 70 mm or less, such as about 65 mm or less, such as about 60 mm or less, such as about 55 mm or less, such as about 50 mm or less, such as about 45 mm or less, or any range or value in between, and on the other hand, it can have a length of about 35 mm to about 50 mm.

[0051] Furthermore, in one aspect, the base of the end cap may also include a groove located around the circumference or edge of the base. For example, the groove may be formed adjacent to the outer edge of the base and may typically have a groove width or diameter of about 15 mm or less, such as about 12.5 mm or less, such as about 10 mm or less, such as about 7.5 mm or less, such as about 1 mm or more, such as about 2.5 mm or more, such as about 5 mm or more, or any range or value therein. The groove may also be located within about 15 mm of the outer edge of the base, such as about 10 mm of the outer edge of the base, such as about 7.5 mm of the outer edge of the base, such as about 5 mm of the outer edge of the base, such as about 1 mm or more of the outer edge of the base, such as about 2.5 mm or more of the outer edge of the base, or any range or value therein.

[0052] While various sizes and dimensions have been discussed in detail above, in one respect, end caps can have a height, inner and outer diameters of the protruding portion, base diameter, and cross-section, the size and selection of which are based on the size of the component, specifically, the distal end of the component containing the electrical components. For example, in one respect, the inner diameter of the end cap is chosen to be larger than the outer diameter of the distal end of the component, while removably holding the distal end of the component within the end cap. For example, the inner diameter can be only slightly larger than the outer diameter of the distal end of the component, such that the end cap will not tilt or rotate once placed on the sensor.

[0053] Additionally or alternatively, while various diameters and shapes of the base have been discussed, in one respect, the diameter and shape of the base are selected based on the gasket, which can be located between the opposing faces of the end cap and the sleeve, or vice versa. That is, in one respect, the diameter and / or shape of the base and the diameter and / or shape of the gasket can be selected to be complementary to each other. For example, a circular gasket can be selected when using a circular base. Furthermore, the diameter of the gasket can be selected to have the same or similar outer diameter as one or more of the end cap base and the sleeve base. In addition, in the case where the end cap base includes a groove, the gasket can have a ridge corresponding to the groove, wherein the width and shape of the ridge are selected to remain within the groove of the end cap base in order to form a liquid-tight seal.

[0054] Therefore, in one aspect, the sealing assembly according to this disclosure may include a sealing gasket. In one aspect, the sealing gasket may have a generally circular shape and may have a diameter of about 35 mm or greater, such as about 40 mm or greater, such as about 45 mm or greater, such as about 50 mm or greater, such as about 70 mm or less, such as about 65 mm or less, such as about 60 mm or less, such as about 55 mm or less, or any range or value therein, and in one aspect, may have a diameter of about 45 mm to about 55 mm.

[0055] Furthermore, in one aspect, the sealing gasket may also include a ridge located around the circumference or edge of the gasket. For example, the ridge may be formed adjacent to the outer edge of the ridge and may typically have a width of about 15 mm or less, such as about 12.5 mm or less, such as about 10 mm or less, such as about 7.5 mm or less, such as about 1 mm or more, such as about 2.5 mm or more, such as about 5 mm or more, or any range or value therein. The ridge may also be located within about 15 mm of the outer edge of the gasket, such as about 10 mm of the outer edge of the gasket, such as about 7.5 mm of the outer edge of the gasket, such as about 5 mm of the outer edge of the gasket, such as about 1 mm or more of the outer edge of the gasket, such as about 2.5 mm or more of the outer edge of the gasket, or any range or value therein.

[0056] In one respect, unlike the base of the end cap, the washer may have ridges that project symmetrically from a first face and an opposite second face. In this manner, the ridges may extend or project from the first face and the opposite second face, wherein the ridges projecting from the first face and the opposite second face have the width and spacing described above. Furthermore, in another respect, the ridges are symmetrically spaced and sized on the first face and the opposite second face.

[0057] Regardless of the gasket's size, it is formed of a material capable of creating a liquid-tight seal between the end cap and the sleeve, and is stable in high-temperature and strong chemical environments. The sealing gasket can be formed of rupture-resistant rubber or elastomer compounds. For example, it can be formed of ethylene propylene diene monomer (EPDM), vinyl methyl silicone rubber (MVQ), polytetrafluoroethylene (PTFE), synthetic rubber and fluoropolymer elastomers (FKM), perfluoroelastomer compounds (FFKM), or combinations thereof. Additionally or alternatively, the gasket can also be formed of plastics or graphite, such as polyvinylidene fluoride (PVDF), flexible graphite / nitrile rubber (Buna-N), polysulfone, or combinations thereof. Of course, alternatively, the gasket can be formed of materials known in the art, selected based on temperature and the chemicals used during cleaning.

[0058] While end caps and sealing gaskets have been discussed in detail so far, the sealing assembly according to this disclosure may also include a sleeve. The sleeve may also have a base and a protrusion, wherein the protrusion of the sleeve may extend from a first end adjacent to the base to a second end; however, both the first end of the protrusion adjacent to the base and the second end of the protrusion may contain openings. Furthermore, the sleeve may define a cavity extending from the opening in the first end to the opening in the second end. As mentioned above, the protrusion may have a cylindrical cross-section; however, as mentioned above, any other cross-section may be chosen, and may be based on the cross-section of the sensor to be covered. Furthermore, in one aspect, the cavity of the sleeve and the cavity of the protrusion may be formed to have substantially the same shape and size, such that the cavities can be aligned when the base of the sleeve and the base of the protrusion are placed together. For example, in this manner, components can be placed into both cavities simultaneously.

[0059] Nevertheless, in one respect, the protruding portion of the sleeve can also be generally cylindrical with openings at the first and second ends. In one respect, the openings in the first and second ends, and the cavity therebetween, can have generally the same diameter (or width), for example, an inner diameter of about 5 mm or greater, such as about 7.5 mm or greater, such as about 10 mm or greater, such as about 12.5 mm or greater, such as about 14 mm or greater, such as about 30 mm or less, such as about 25 mm or less, such as about 22.5 mm or less, such as about 20 mm or less, such as about 17.5 mm or less, such as about 15 mm or less, or any range or value between these, and in one respect, can have a diameter of about 10 mm to about 20 mm. Of course, depending on the diameters described above, each opening can be chosen to have the same diameter or different diameters. In one respect, the openings have generally the same diameter; however, in another respect, the protruding portion of the sleeve (or end cap) can have a tapered cross-section (e.g., conical, if typically spherical), such that the diameter of the distal opening differs from the diameter of the proximal opening.

[0060] In addition, the protruding portion of the sleeve may have an outer diameter of about 17.5 mm or greater, such as about 20 mm or greater, such as about 22 mm or greater, such as about 25 mm or greater, such as about 30 mm or greater, such as about 45 mm or less, such as about 40 mm or less, such as about 35 mm or less, such as about 32.5 mm or less, such as about 30 mm or less, such as about 27.5 mm or less, such as about 25 mm or less, or any range or value therein, and in one aspect, may have an inner diameter of about 20 mm to about 30 mm.

[0061] Furthermore, disregarding the cross-section and diameter chosen for the sleeve, on one hand, the base of the sleeve can typically have a diameter (or width, if a non-circular cross-section is used) that is approximately 1.5 times the inner diameter of the protrusion, such as approximately 2 times the inner diameter, such as approximately 2.4 times the inner diameter of the protrusion, such as approximately 2.7 times the inner diameter of the protrusion, such as approximately 3 times the inner diameter of the protrusion, such as approximately 3.5 times the inner diameter of the protrusion.

[0062] Regardless of the diameter ratio, on one hand, the base of the sleeve can have a diameter of about 35 mm or greater, such as about 40 mm or greater, such as about 45 mm or greater, such as about 50 mm or greater, such as about 70 mm or less, such as about 65 mm or less, such as about 60 mm or less, such as about 55 mm or less, or any range or value between therewith, and on another hand, it can have a diameter of about 45 mm to about 55 mm. Furthermore, on another hand, the diameter of the sleeve base is generally the same as the diameter of the end cap base. Additionally or alternatively, as described above, the base of the sleeve can be selected to have approximately the same size and shape as the sealing gasket.

[0063] Furthermore, regardless of the cross-section and diameter chosen for the sleeve, on one hand, the length of the protruding portion of the sleeve between the first end and the second end can be about 1 mm or more, such as about 2.5 mm or more, such as about 5 mm or more, such as about 7.5 mm or more, such as about 10 mm or more, such as about 12 mm or more, such as about 25 mm or less, such as about 22.5 mm or less, such as about 20 mm or less, such as about 17.5 mm or less, such as about 15 mm or less, or any range or value therein, and on one hand, it can have a length of about 7.5 mm to about 15 mm.

[0064] Additionally or alternatively, in one aspect, the base of the sleeve may also include a groove located around the circumference or edge of the base. For example, the groove may be formed adjacent to the outer edge of the base and may typically have a groove width or diameter of about 15 mm or less, such as about 12.5 mm or less, such as about 10 mm or less, such as about 7.5 mm or less, such as about 1 mm or more, such as about 2.5 mm or more, such as about 5 mm or more, or any range or value therein. The groove may also be located within about 15 mm of the outer edge of the base, such as about 10 mm, such as about 7.5 mm, such as about 5 mm, such as about 1 mm or more, such as about 2.5 mm or more, or any range or value therein. In one aspect, the groove of the sleeve may have the same dimensions as the groove of the end cap. In another aspect, the dimensions and orientation of the groove of the sleeve and the groove of the end cap may be configured to receive a corresponding ridge in the sealing gasket.

[0065] While various sizes and dimensions have been discussed in detail above, in one respect, the sleeve can have a height, inner diameter, base diameter, and cross-section determined and selected based on the size of the sensor, specifically, the portion of the component body adjacent to the electrical component to be protected, which begins to contain the electrical component (e.g., the portion of the sensor body adjacent to and preceding the electrical component when moving from the proximal measuring end of the sensor to the distal end containing the electrical component). For example, in one respect, the inner diameter of the sleeve is selected to be larger than the outer diameter of the portion of the component body adjacent to the electrical component, such that the sleeve can be placed around the sensor body and form a liquid-tight seal. For example, the inner diameter of the cavity of the sleeve protrusion may be only slightly larger than the outer diameter of the sensor portion adjacent to the electrical component, such that the sleeve will not tilt or rotate once placed on the component or sensor.

[0066] Although the protruding portion of the sleeve has the aforementioned diameter, in one aspect, the shape and size of the sleeve are configured to surround the sensor body, such that the base of the sleeve is located directly below the electrical components of the sensor. (See example) Figure 5 Therefore, in this respect, the end cap can extend from the distal end of the sensor to the base of the sleeve, such that the base of the end cap faces the base of the sleeve.

[0067] Additionally or alternatively, in one aspect, the inner surface of the sleeve protrusion may have an etched or otherwise patterned rib or thread pattern on or within its surface. For example, in one aspect, the sleeve may have a ribbed design or surface pattern to more securely attach to the sensor body while remaining removable. Alternatively, the inner surface may have a threaded groove pattern that complements the threaded grooves on the sensor body adjacent to the electrical components. Of course, as mentioned above, in one aspect, the inner surface may not have any pattern or etching.

[0068] Regardless of the shape and size of the end caps and sleeves chosen, they can typically be formed from rupture-resistant materials, such as the gasket materials discussed above. However, end caps and sleeves can alternatively be formed from metals or alloys thereof that have good resistance to strong chemicals and high temperatures. For example, end caps and sleeves can be formed from stainless steel. Of course, it should be understood that end caps and sleeves can also be formed from different materials.

[0069] While the sleeve, end cap, and sealing gasket have been discussed in detail above, in one aspect, the sealing assembly also includes a clamp. For example, in one aspect, the clamp may be a single-pin, double-pin, high-pressure, safety, locking, three-section, or other process clamp known in the art. Regardless of the type of clamp chosen, the claims are configured to at least contact the sleeve and end cap to facilitate a liquid-tight seal between the end cap and sleeve. Furthermore, in one aspect, the clamp may be a single-pin clamp capable of forming a liquid-tight seal.

[0070] Regardless of the type and material chosen for the clamp, on one hand, the clamp can have an inner diameter of about 17.5 mm or greater, such as about 20 mm or greater, such as about 22 mm or greater, such as about 25 mm or greater, such as about 30 mm or greater, such as about 45 mm or less, such as about 40 mm or less, such as about 35 mm or less, such as about 32.5 mm or less, such as about 30 mm or less, such as about 27.5 mm or less, such as about 25 mm or less, or any range or value between these, and on the other hand, it can have an inner diameter of about 20 mm to about 30 mm. Generally, the clamp can be selected to have a size corresponding to the outer diameter of the sleeve and / or end cap to facilitate a liquid-tight seal with the sealing assembly.

[0071] Despite the choice of clamp type, clamps can typically be formed from fracture-resistant rigid plastics. However, clamps can alternatively be formed from metals or alloys thereof that have good resistance to strong chemicals and high temperatures. For example, clamps can be formed from stainless steel. Of course, it should be understood that other materials known in the art can also be used to form clamps.

[0072] While the features of the sealing assembly have been discussed so far, in one aspect, the sealing assembly according to this disclosure may further include a retainer configured to cooperate with the end cap to hold the component or sensor in a generally horizontal position for a period of time. In particular, as is generally known in the art, many automated cleaning mechanisms utilize upper and lower cleaning mechanisms to properly clean the component. Therefore, a further benefit is to provide a retainer that works in conjunction with the sealing assembly to hold the sensor in a generally horizontal position for a period of time.

[0073] Therefore, in one aspect, this disclosure further includes a retainer having a retainer body with one or more holes. The retainer body may have a generally rectangular shape, wherein the lengths of the two first opposing sidewalls are longer than the lengths of the two second opposing sidewalls. For example, the two first opposing sidewalls may have lengths of about 100 mm to about 600 mm, such as about 150 mm to about 550 mm, such as about 200 mm to about 500 mm, such as about 250 mm to about 450 mm, such as about 300 mm to about 400 mm, or any range or value between these. It should be understood, of course, that the lengths of the two first opposing sidewalls may be increased or decreased depending on the number of sensors that need to be supported.

[0074] Furthermore, on one hand, the second opposing sidewall may have a height of approximately 25 mm to approximately 200 mm, such as approximately 50 mm to approximately 175 mm, such as approximately 50 mm to approximately 150 mm, such as approximately 75 mm to approximately 125 mm, or any range or value between these. Of course, as mentioned above, it should also be understood that if a greater number of sensors, or larger or smaller sensors, are used, the length of the second opposing sidewall may be increased or decreased accordingly.

[0075] Furthermore, in one aspect, the retainer body may have a thickness of approximately 5 mm to approximately 25 mm, such as approximately 7.5 mm to approximately 22.5 mm, such as approximately 10 mm to approximately 20 mm, such as approximately 12.5 mm to approximately 17.5 mm, or any range or value therebetween. However, while the retainer body and one or more arms may have the same thickness, in one aspect, the retainer body and one or more arms may have different thicknesses, each thickness according to the foregoing. Furthermore, in one aspect, the retainer body has a leg with a width approximately 1.1 times the width of the retainer body, such as approximately 1.2 times the width, such as approximately 1.4 times the width, such as approximately 1.6 times the width, such as approximately 1.8 times the width, such as approximately 2 times the width of the retainer body. Therefore, in one aspect, the leg of the retainer body may have a width of approximately 15 mm to approximately 45 mm, such as approximately 20 mm to approximately 40 mm, such as approximately 25 mm to approximately 35 mm, or any range or value therebetween.

[0076] Additionally or alternatively, the retainer may also include a rear body having the size, shape, and components discussed above regarding the retainer body. In this respect, the rear body may be connected to the retainer body by one or more arms, which will be discussed in more detail below. Thus, in this respect, the retainer may have a generally quadrilateral shape, wherein the retainer body is opposite to the rear body, forming the first and second sides of the retainer, and at least one arm is opposite to an optional second arm, forming opposing third and fourth sides of the retainer. Of course, in one respect, as mentioned above, the rear body may be optional.

[0077] Regardless of the size of the sidewalls, the retainer may include at least one hole, such as at least two holes, such as at least three holes, such as at least four holes, such as at least five holes, such as ten holes or less, such as nine holes or less, such as eight holes or less, such as seven holes or less, such as six holes or less, such as five holes or less, such as four holes or less. In one aspect, the retainer has two to four holes.

[0078] Regardless of the number of holes, in one respect, the diameter of at least one hole is generally equal to the outer diameter of the end cap protrusion. In this way, the end cap protrusion can be placed into the hole of the retainer and extend through the hole to retain the end cap protrusion within the hole. Thus, in one respect, at least one hole may have a diameter of about 17.5 mm or greater, such as about 20 mm or greater, such as about 22 mm or greater, such as about 25 mm or greater, such as about 30 mm or greater, such as about 45 mm or less, such as about 40 mm or less, such as about 35 mm or less, such as about 32.5 mm or less, such as about 30 mm or less, such as about 27.5 mm or less, or any range or value therein, and in one respect, may have an outer diameter of about 20 mm to about 30 mm.

[0079] Furthermore, when using two or more holes, the center-to-center spacing of the holes can be from about 60 mm to about 300 mm, such as from about 75 mm to about 250 mm, such as from about 85 mm to about 200 mm, such as from about 100 mm to about 150 mm, or any range or value in between.

[0080] On one hand, the hole may be open and can be simply formed by a cut in the retainer body or rear body having a cross-section corresponding to the cross-section of the end cap. In this aspect, the thickness of the retainer body or rear body and the diameter of the hole can be selected to support the end cap within the hole. However, on the other hand, the hole may be closed and may include a proximal end formed in one or more of the retainer body and rear body, and may extend to a distal end, forming a cavity between them having a length at least sufficiently long to receive a protrusion of the end cap. In this aspect, the distal end may be adjacent to the opposite side of the retainer body and rear body located at the proximal end.

[0081] Additionally or alternatively, in one aspect, when two or more holes are used, the proximal ends of one or more holes may be formed in the retainer body, and the proximal ends of one or more holes may be formed in the rear body. Thus, in this aspect, a first end cap placed in the hole with its proximal end in the retainer body can extend from an end cap placed in the hole with its proximal end in the rear body in opposing directions. Of course, in another aspect, all the holes may extend in substantially the same direction.

[0082] In one aspect, the retainer may have one or more arms extending from one or both ends of the first opposing sidewalls of the retainer body and / or the rear body, and in another aspect, the one or more arms may be two arms extending from opposing ends of the first opposing sidewalls of the retainer body and / or the rear body. In particular, the one or more arms may extend from the retainer body and / or the rear body in a generally vertical direction, such as at an angle of about 45° to about 135°, such as about 55° to about 125°, such as about 65° to about 115°, such as about 75° to about 105°, such as about 80° to about 100°, or any range or value therebetween.

[0083] One or more arms can typically have a length of about 25 mm to about 200 mm, such as about 50 mm to about 175 mm, such as about 50 mm to about 150 mm, such as about 75 mm to about 125 mm, or any range or value between them. Furthermore, in one aspect, the length of one or more arms can be selected to be approximately or greater than the length of the protrusion of the end cap in order to provide sufficient stability for the sensor, and as mentioned above, in one aspect, the retainer body can be connected to the rear body.

[0084] Nevertheless, one or more arms may have a height of about 25 mm to about 200 mm, such as about 50 mm to about 175 mm, such as about 50 mm to about 150 mm, such as about 75 mm to about 125 mm, or any range or value therein, and in one respect, may have a height that is approximately the same as the length / height of the second opposing wall of the retainer body.

[0085] Furthermore, in one aspect, one or more arms may have a width substantially the same as the width of the retainer body, such as one of the ranges described above. Similarly, in one aspect, one or more arms, retainer bodies, and / or rear bodies may each have a foot such that the total width of the arm, retainer body, or rear body, and the foot is approximately 1.1 times the width of the arm, retainer body, or rear body, such as approximately 1.2 times the width, for example, approximately 1.4 times the width, such as approximately 1.6 times the width, such as approximately 1.8 times the width, such as approximately 2 times the width of the arm, retainer body, or rear body. Thus, in one aspect, one or more arms, retainer bodies, or rear bodies may each have a foot with a width of approximately 15 mm to approximately 45 mm, such as approximately 20 mm to approximately 40 mm, such as approximately 25 mm to approximately 35 mm, or any range or value therebetween. Furthermore, in one aspect, one or more feet may extend the entire length of one or more arms, retainer bodies, or rear bodies, or alternatively, protrusions may be formed only at the intersections of the arms and retainer bodies and / or rear bodies.

[0086] Additionally or alternatively, in one aspect, one or more legs may be shaped to releasably interlock with one or more legs of the second retainer. In this aspect, the retainers may be stacked such that the second retainer is releasably secured above the first retainer. Thus, in this aspect, the retainer may have one or more legs extending downward at the intersection of the arm and the retainer body and / or the rear body, and may also have one or more legs extending upward at the intersection of the arm and the retainer body and / or the rear body. In another aspect, one or more legs may have opposite shapes such that one or more legs of the first retainer can be interchanged with any one or more legs of the second retainer.

[0087] For example, as will be discussed in more detail below regarding Figure 8A and Figure 8B On one hand, the legs can have a width in which both the protrusions and recesses are included. On the other hand, the ends of the legs, away from the retainer body, the rear body, or one or more arms, include both recesses and protrusions. Thus, in this way, the recesses of the legs on the first retainer can receive the protrusions of the legs on the second retainer, and vice versa.

[0088] Although various aspects have been discussed so far, this disclosure can be further understood based on the following discussion of the accompanying drawings.

[0089] For example, such as Figure 1 As shown, the sealing assembly 100 according to this disclosure typically includes a sealing clamp 102, an end cap 104, and a sleeve 106. As described above, the end cap 104 includes a second fully closed end 108 located on a protrusion 110 of a base 112 remote from the end cap 104. Figure 2A and Figure 2B (As shown more clearly in the image). Furthermore, sleeve 106 includes a protrusion 114 with an open distal end 116, such that sleeve 106 can accommodate sensor 118 passing through cavity 120 (in... Figure 2A and Figure 2B (This is shown more clearly in the text).

[0090] In particular, such as Figure 2A As shown in FIG. 2, the end cap 104 has a base 122 and a protrusion 110, and the sleeve 106 has a protrusion 114 and a base 124. Furthermore, as shown in FIG. 2, the base 124 of the sleeve 106 includes a groove 126, and the base 122 of the end cap 104 includes a groove 128. As described above and as shown in FIG. 2, in one aspect, the groove 126 of the sleeve 106 and the groove 128 of the end cap 104 may have substantially the same size and shape to mate with the gasket 130 to form a liquid-tight seal, such as... Figure 2B As shown. Furthermore, as... Figure 2AAs generally shown in the other figures, the cavity 120 of the sleeve 106 may have approximately the same shape and size as the cavity 121 of the end cap 104, such that cavities 120 and 121 can be aligned. In this way, the sensor 118 can be placed through the cavity 120 of the sleeve 106 and simultaneously placed into the cavity 121 of the body cap 104.

[0091] For example, as described above, in one aspect, the sealing gasket 130 may include a ridge 132, the shape and size of which mate with the groove 126 of the sleeve 106 and the groove 128 of the end cap 104 to form a liquid-tight seal when clamped. Therefore, in one aspect, the ridge 132 may have a width w corresponding to the diameter or width of the grooves 126, 128, and may be located at a width w2 at a distance from the outer edge 142 of the gasket. Thus, as... Figure 2B As shown, in one respect, the ridge 142 may be located around the washer 130 in the circumferential direction and may be located at a constant width w2 from the outer edge 142.

[0092] As described above, the sealing gasket 130 may have an inner diameter d1, which is typically the same as the inner diameter of the sleeve and / or end cap, which will... Figure 3D and Figure 4D This is shown and discussed in more detail below. Furthermore, the sealing gasket 130 may have an outer diameter d2, which is typically the same as the outer diameter of the sleeve and / or end cap, which will... Figure 3D and Figure 4D The details are shown and discussed in more detail below.

[0093] Nevertheless, now will Figures 3A to 3E The end cap 104 will be discussed in more detail. For example, as... Figure 3A and Figure 3B As shown, the end cap 104 has a base 122 and a protrusion 110. The protrusion has a first end 134 and a fully enclosed second end 108, as well as an outer diameter d3. Furthermore, in one aspect, the second end 108 may have a tapered portion 136 that transitions the protrusion 110 to the second end 108. Additionally, as... Figure 3A and Figure 3B As shown, the base 122 has an outer diameter d6, and in one aspect, the base 122 has a lip 138 that is generally parallel to the protrusion 110, although not essential, this provides a further improved sealing surface. Nevertheless, in one aspect, when the base 122 includes the lip 138, the base may have an angled portion 140, which may be generally flat or alternatively convex, and the base may transition from the first end 134 of the protrusion 110 to the lip 122.

[0094] In addition, refer to Figure 3C and Figure 3DThe images show a bottom perspective view and a top view of the end cap 104, respectively. In one aspect, the base 122 of the end cap 104 includes a recess 128 located around the base 122 in a generally circumferential direction. Figure 3D As generally shown, the groove 128 may have a diameter d5 (which may approximately correspond to the width w of the ridge 132 of the washer 130) and may be located at a distance w3 from the outer edge 144 of the base 122 (which may be approximately equal to the distance w2 from the corresponding ridge 132 of the washer 130 to the outer edge 142 of the washer 130). Additionally, as described above, the base 122 may have an outer diameter d6, which, in one aspect, may be approximately the same as the outer diameter d2 of the washer 130. Furthermore, since the protrusion 110 has a fully enclosed second end 108, Figure 3D Provides the clearest view of the inner diameter d4 of the protrusion 110.

[0095] at last, Figure 3E A top view of the end cap 104 is shown. Specifically, the end cap 104 has a base 122 with an outer diameter of d6 and a protrusion 110 with an outer diameter of d3. Furthermore, as previously mentioned, in one aspect, the fully enclosed second end 108 may have a tapered portion 136.

[0096] Although end cap 104 has been discussed in detail so far, reference will now be made to... Figures 4A to 4E Sleeve 106 is described in further detail. For example, as... Figure 4A and Figure 4B As shown, the sleeve 106 has a base 124 and a protrusion 114. The protrusion 114 has a first end 146 and a second end 148, and an outer diameter d7. As described above, the sleeve 114 also includes a cavity 120 extending from the first end to the second end, and has a diameter d7. 12 (exist Figure 4D (shown more clearly in the figure), which may roughly correspond to the inner diameter d4 of the protrusion 110 of the end cap 104 and / or the outer diameter of the component or sensor 118 used with the sealing assembly 100 according to the invention. Furthermore, as mentioned above, in one aspect, the cavity 120 may include threads or threaded grooves, generally indicated by reference numeral 154.

[0097] Additionally, such as Figures 4A to 4CAs shown, the base 124 has an outer diameter d8, and in one aspect, the base 124 has a lip 150 that is generally parallel to the protrusion 114, although not essential, this provides a further improved sealing surface. Nevertheless, in one aspect, when the base 124 includes the lip 150, the base 124 may have an angled portion 152, which may be generally flat or alternatively convex, and the base 124 may transition from the first end 146 of the protrusion 114 to the lip 150.

[0098] In addition, refer to Figure 4B and Figure 4D The figures show a bottom perspective view and a top view of the sleeve 106, respectively. In one aspect, the base 124 of the sleeve 106 includes a recess 126 located around the base 124 in a generally circumferential direction. Figure 4D As generally shown, the groove 126 may have a diameter d9, which may correspond approximately to the width w of the ridge 132 of the washer 130 and / or the diameter d5 of the ridge 128 of the end cap 104, and may be located at a distance w4 from the outer edge 156 of the base 124, which is generally equal to the distance w2 from the corresponding ridge 132 of the washer 130 to its outer edge 142, or the distance w3 from the corresponding groove 128 of the end cap 104 to its corresponding outer edge 144. Additionally, as described above, the base 124 may have an outer diameter d8, which, in one aspect, may be approximately the same as the outer diameter d2 of the washer 130 or the outer diameter d6 of the base 122 of the end cap 104.

[0099] at last, Figure 4E A top view of the sleeve 106 is shown. Specifically, the sleeve 106 has a base 124 with an outer diameter of d8 and a protrusion 114 with an outer diameter of d7. Furthermore, as previously described, an opening 120 extends through the sleeve 106, allowing sensors, etc., to be placed inside or through the opening.

[0100] For example, refer to Figure 5 A portion of the sealing assembly is shown as part of a sensor 118 surrounding an adjacent electrical component 156. Specifically, as described above, a sleeve 106 is placed around the sensor 118 and positioned at the distal end of a sensor 158 adjacent to the electrical component 156. The recess 126 of the base 106 of the sleeve 106 faces the electrical component 156 such that, when placed on the electrical component 156, the corresponding recess 128 of the end 105 and / or the ridge 132 of the washer 130 can contact the recess 126 of the sleeve 106.

[0101] Next, refer to Figures 6A to 6CThe clamp 102 according to this disclosure will be discussed in more detail. For example, in this aspect, a two-section clamp with a manually tightening closure 160 is shown. For example, in this aspect, the two-section clamp can be tightened by rotating the closure 160 until it is hand-tightened, thereby creating a liquid-tight seal between the sleeve 106, the end cap 104, and the sealing gasket 130. Of course, as mentioned above, various types of clamps and closures can be used. Additionally, in one aspect, the clamp 102 may have an inner diameter d. 10 The inner diameter can be approximately equal to the outer diameter d7 of the protruding portion 114 of the sleeve 106 and / or the outer diameter d3 of the protruding portion 110 of the end cap 104. Furthermore, as... Figure 6B As shown, the clamp 102 may also include a recess 162, the shape and size of which are adapted to receive the sleeve 106, the end cap 104 and the sealing gasket 130 in the recess.

[0102] Finally, while one or more aspects of the sealing assembly 100 have been discussed in great detail above, on the other hand, the retainer 200 can be used to hold the sensor 118 and the cleaning assembly 100 in a generally horizontal position for a period of time. For example, refer to Figures 7A to 7E The retainer 200 may include a retainer body 202 having one or more holes 204, with a length of l and a height of h (an end cap 104 is shown in the proximal end 210 of the insertion hole 204 for reference). The retainer 200 may also include one or more arms 206 having a length of l2 extending from the retainer body 202 in a generally perpendicular direction. As shown, the retainer body 202 and the one or more arms 206 may each have a thickness t. Furthermore, as described above, in one aspect, the one or more arms 206 and the retainer body 202 may each have a foot 208 extending from the bottom (surface contact) side of the one or more arms 206 and / or the retainer body 202. For example, as shown, when in use, the one or more feet may have a thickness t2 (which is approximately twice the thickness t of the arm 206 or the retainer body 202) and extend the entire length l of the retainer body. In any case, the retainer 200 is able to hold the sealing assembly and the sensor in a position that is approximately perpendicular to the retainer body 202 and parallel to the surface on which the retainer 202 is placed.

[0103] Next reference Figure 8A and Figure 8B As described above, in one aspect, the retainer 300 may have one or more holes 302 configured to receive the end cap 304 (shown in the proximal end 306 of the end cap 304 insertion hole 302). Furthermore, as shown in the exploded view, the sealing gasket 308, sealing clamp 310, and sleeve 312 may cooperate together to form a sealing assembly. Figure 8A and Figure 8BAs shown, in one aspect, the aperture 302 can be closed. In this aspect, the proximal end 306 can be open, and the distal end 322 can be closed, wherein a cavity (not shown) extends from the proximal end 306 to the distal end 322. Furthermore, as... Figure 8A and Figure 8B As shown, in one aspect, a proximal end 306 of a hole 302 may be formed in the holder body 314, and a second hole 302 may have its proximal end 306 formed in the rear body 316, such that the holes extend in opposite directions.

[0104] Nevertheless, such as Figure 8A and Figure 8B As shown, the retainer 300 may have a retainer body 314, a rear body 316, and one or more arms 318. Additionally, as... Figure 8A and Figure 8B As shown, the support leg 320 may form a protrusion extending from the intersection of the retainer body 314 and one or more arms 318, or the rear body 316 and one or more arms 318. As described above, in one aspect, the one or more support legs 320 may have a width w, wherein a recessed portion 324 and a protruding portion 326 are formed in the width w. In this manner, as... Figure 8B As shown, two or more retainers 300 can be stacked via the protrusions 326 and recesses 324 of the interlocking legs 320. For example, in this respect, the rear body 316 of the second retainer 300 can be positioned above the retainer body 314 of the first retainer 300, such that the protrusions 326 and recesses 324 of the legs can interlock to releasably hold the second retainer 300 in place above the first retainer 300. Figure 8B As shown, in this respect, the six components (three for each retainer) can be kept in a horizontal position during the cleaning cycle.

[0105] These and other modifications and variations to the invention can be made by those skilled in the art without departing from the spirit and scope of the invention, which is more specifically set forth in the appended claims. Furthermore, it should be understood that aspects of the various embodiments can be interchanged, in whole or in part. Moreover, those skilled in the art will understand that the foregoing description is merely exemplary and is not intended to limit the invention further described in the appended claims.
