Description

Technical Field

[0001] The present disclosure provides a filter cleaning system, which includes a filter cleaning device, the filter cleaning device including a tubular rod column arranged on a support bar in a rotating manner. One or more filter holders suitable for holding a filter can be arranged on the tubular rod column. The filter arranged on the tubular rod column can rotate around the support bar. A fluid flow can be directed to the filter to clean the filter rotating around the support bar. Background Art

[0002] The filter may be cleaned periodically to remove contaminants that may increase the filtration pressure of the filter element. For pool and spa filters, contaminants in the liquid fluid stream such as: leaves, algae, sand, skin cells, body oils may be difficult to remove from the pleats in the filter. Similarly, in the case of a gas or air filter, contaminants such as: airborne particles and liquid aerosols, smoke, mold spores and pollen may be difficult to remove from the pleats in the filter.

[0003] A filter cleaning system that allows the filter to rotate relative to the fluid flow of liquid or gas would provide significant advantages in reducing the labor and cost of periodically cleaning the filter pleats to reduce filter pressure and ensure long filter life. Utility Model Content

[0025] Usually, reference Figures 1 to 16, these figures depict various embodiments of a filter cleaning device (1) and a method of making and using the filter cleaning device (1), wherein the filter cleaning device includes one or more of the following: a base (2) that supports a rod (3); a tubular rod column (4) having a length disposed between an open end (5) of the rod column and a closed end (6) of the rod column, wherein the rod (3) inserted into the tubular rod column (4) contacts the closed end (6) of the rod column, and wherein the tubular rod column (4) having the closed end (6) of the rod column contacting the rod column (3) rotates around the rod (3); and one or more filter holders (7) that can be positioned on the tubular rod column (4) to hold one or more filters (8). The term "filter" broadly encompasses any filter (8) that may be positioned on the tubular pole (4), and, without limiting the foregoing breadth, includes the following as illustrative examples: liquid filters, water filters, gas filters, air filters, pleated filters, non-pleated filters, dust filters, shop vacuum filters, in-ground pool filters, above-ground pool filters, spa filters, swim spa filters, cooler filters, ice rink water filters, inflatable spa filters, and the like.

[0026] Now, the main reference Figures 1 to 7 and Figures 14 to 16 In certain embodiments, the filter cleaning device (1) may optionally include a base (2) which may be placed or held on a support surface (9). The base (2) may be configured as a support bar (3). Figures 1 to 7 and Figures 14 to 16 A circular base (2) is depicted which is secured to a support surface (8) by one or more fasteners (9), but this is not intended to exclude embodiments of the filter cleaning apparatus (1) in which the base (2) is otherwise configured to support the bar (3), with or without fasteners (9), and with a greater or lesser contact area with the support surface (9), and with a base perimeter (11) of any suitable form defining a base area suitable for supporting the bar (3); or in particular embodiments, the base may be configured as a stand with foldable legs; or in particular embodiments, the base (2) may not be utilized and the bar (3) may be directly attached, connected or coupled to the support surface (9) or inserted into the support surface. In particular embodiments, the base (2) may include a tubular conduit (12) having a tubular conduit interior surface (13) configured to maintain the bar (3) in a spatially fixed outwardly extending relationship with the support surface (9). In the depicted embodiment, the tubular conduit (2) terminates in a conduit end fitting (14) having an end fitting aperture (15) through which the rod (3) passes to be held in a spatially fixed extended relationship with the base (2).

[0027] Now, the main reference Figure 4 , Figure 7 , Figure 10-13 and Fig.16 , an embodiment of the bar (3) may include a bar straight portion (15) disposed between first bar ends (16) that may be secured to a base (2) or support surface (8) and terminating at a second bar end (17).

[0028] Now, the main reference Figures 1 to 7 and Figures 10 to 16 , embodiments of the filter cleaning apparatus (1) may further include a tubular stem (4) disposed between the stem open end (5) and the stem closed end (6). In certain embodiments, the stem open end (5) may terminate in a stem end fitting (28) having a stem end fitting aperture (18) (e.g., Fig.10 The rod end fitting aperture (20) can engage the rod (3) in a rotational manner to restrict translational movement of the tubular rod (4) in a direction opposite to the rod (3) disposed in the tubular rod (4). The rod (3) can be inserted into the tubular rod (4) so ​​that the rod second end (18) contacts the rod closed end (6). The tubular rod (4) with the rod closed end (6) contacting the rod second end (18) can be rotated around the rod (3).

[0029] Now, the main reference Fig.11 , Fig. 12A , Fig. 12B and Fig.13 In certain embodiments, the protrusion (21) may extend from the closed end (6) of the rod. The protrusion (21) may be configured to contact the second end (18) of the rod (3) inserted into the tubular rod (4). The protrusion (21) may gradually narrow as it approaches the protrusion end (22). The protrusion end (21) may contact the second end (18) of the rod (3) when the rod (3) is inserted into the tubular rod (4). In certain embodiments, the protrusion (21) gradually narrows to a protrusion point (23). The protrusion point (23) may contact the second end (18) of the rod when the rod (3) is inserted into the tubular rod (4). The protrusion (21) may reduce the contact area between the protrusion end (21) and the second end (18) of the rod when it gradually narrows or gradually narrows to the protrusion point (23). This may bring the significant advantage of reducing friction between the closed end (6) of the rod and the second end (18) of the rod. In certain embodiments, the second end (18) of the rod may include a central recess (24). The rod (3) inserted into the tubular rod (4) may contact the central recess (24) with the end (21) of the protrusion extending from the closed end (6) of the tubular rod (4). Fig. 12A and 12BAs shown in the example, a protrusion (21) that contacts the second end (18) of the rod or a central recess (24) in the second end (18) of the rod positions the second end (18) of the rod at a distance from the closed end (6) of the tubular pole, thereby allowing the tubular pole to rotate or rotate freely around the rod (3).

[0030] Now, the main reference Fig.13 In certain embodiments, the closed end (6) of the tubular stem (4) may hold a bearing (25). The bar (3) inserted into the tubular stem (4) may contact the bearing (25) to facilitate rotation of the tubular stem (4) around the bar (3). The second bar end (18) may be configured to engage the bearing (25) held in the closed end (6) of the tubular stem (4). The bearing (25) may take any form that allows the bearing (25) to engage with the second bar end (18) and allow the tubular stem (4) to rotate around the bar (3). The bearing (25) may include a rolling element (26) between an outer race (27) engaging the tubular stem (4) and an inner race (28) engaging the second bar end (18), thereby allowing the tubular stem (4) to rotate around the bar (3). As illustrative examples, the bearing (25) may include a thrust bearing (25a) or a roller bearing (25b).

One or more filter holders (7) may be configured to engage a filter (8) positioned on the tubular stem (4). In certain embodiments, only one filter holder (7) may be positioned on the tubular stem (4). In other embodiments, a pair of filter holders (7a, 7b) may be positioned on the tubular stem (4). The first filter holder (7a) may have the same configuration as the second filter holder (7b), or the first filter holder (7a) may have a different configuration than the second filter holder (7b). The filter holder (7) may be adapted to be inserted into a filter end opening (29) of the filter (7) to support the filter (7) on the tubular stem (4).

[0032] like Figures 5 to 9As depicted in , in certain embodiments, the filter holder (7) may taper between the filter holder first end (30) and the filter holder second end (31), and in some examples, take the form of a cone (32) or a truncated cone (33). The filter holder (7) in the form of a cone (32) or a truncated cone (33) may be slidably disposed in the filter end opening (29) until the filter holder (7) engages the filter end opening (29) to support the filter (8) on the tubular stem (4).

The diameters of the two or more annular components (35) may be configured to insertably engage corresponding two or more filter end openings (29) of different diameters of a filter (8) positionable on a tubular stem (4). The annular member (35) near the first end (30) of the filter holder may have a diameter for engaging the filter end opening (29) of the expected maximum diameter of the filter (8), and the annular member (35) away from the first end (30) of the filter holder may have a diameter for engaging the filter end opening (29) of the expected minimum diameter of the filter (8). The diameters of the two or more annular members (35) arranged in the stepped annular conical reduction (34) may correspond to the diameters of the filter end openings (29) of filters (8) that are commercially available or expected to require repeated cleaning. The filter holder (7) in the form of a stepped annular conical reduction (34) can be slidably arranged in the filter end opening (29) until one of the annular member side walls (36) abuts against or engages the filter end opening (39), wherein the filter (8) is supported on the rear larger diameter annular member (35) in the stepped annular conical reduction (34).

[0062] From the foregoing, it can be readily understood that the basic concept of the present invention can be embodied in a variety of ways. The present invention relates to numerous different embodiments of filter cleaning devices and methods for making and using such filter cleaning devices, including the best mode.

[0063] Therefore, the specific embodiments or elements of the present invention disclosed by the specification or shown in the drawings and tables accompanying this application are not intended to be limiting, but rather examples of many different embodiments generally covered by the present invention or equivalents covered with respect to any specific element thereof. In addition, the specific description of a single embodiment or element of the present invention may not explicitly describe all possible embodiments or elements; the specification and drawings implicitly disclose many alternatives.

[0064] It should be understood that each element of a device or each step of a method can be described by a device term or a method term. Such terms can be replaced when necessary so that the implicit broad coverage of the utility model authorization is clarified. As just one example, it should be understood that all steps of a method can be disclosed as actions, devices for taking the actions, or elements causing the actions. Similarly, each element of a device can be disclosed as a physical element or an action promoted by the physical element. As just one example, the disclosure of a "holder" should be understood to cover the disclosure of a "holding" action-whether or not explicitly discussed-and on the contrary, if a "holding" action is disclosed, such disclosure should be understood to cover the disclosure of a "holder" and even a "device for holding". Such alternative terms for each element or step should be understood to be explicitly included in the specification.

[0065] In addition, with respect to each term used, it should be understood that unless the usage of the term in this application is inconsistent with such interpretation, the commonly used dictionary definition should be understood to be contained in the description of each term contained in the Random House Webster's Unabridged Dictionary, Second Edition, each definition being incorporated herein by reference.

[0066] It is assumed that all numerical values ​​herein are modified by the term "about", whether or not explicitly stated. For the purpose of the present invention, the range can be expressed as from "about" a specific value to "about" another specific value. When such a range is represented, another embodiment includes from one specific value to another specific value. The numerical range expressed by the endpoint includes all numerical values ​​contained in the range. The numerical range of one to five includes, for example, numerical values ​​1, 1.5, 2, 2.75, 3, 3.80, 4, 5, etc. It should be further understood that the endpoints of each range in the range are significant in terms of both relative to another endpoint and independently of another endpoint. When the antecedent "about" is used to express the value as an approximate value, it should be understood that the specific value forms another embodiment. The term "about" generally refers to a series of numerical values ​​that a person of ordinary skill in the art considers to be equivalent to the stated numerical value or to have the same function or result. Similarly, the antecedent "substantially" represents the same form, mode or degree to a large extent but not completely, and a specific element will have a series of configurations with the same function or result that a person of ordinary skill in the art will consider. When the antecedent “substantially” is used to express a particular element as an approximation, it should be understood that the particular element forms another embodiment.

[0067] In addition, for the purpose of the present invention, unless otherwise limited, the term "a / an" entity refers to one or more of the entity. Therefore, the terms "a" or "an", "one or more" and "at least one" are used interchangeably herein.

[0068] Furthermore, for purposes of the present invention, the term “coupled” or its derivatives may mean indirectly coupled, coupled, directly coupled, connected, directly connected, or integrated with, depending on the embodiment.

[0069] Additionally, for the purposes of the present invention, the term "integrated" when referring to two or more components means that the components (i) can be combined together to provide a single-piece construction, an integral construction, or a unified entity, or (ii) can be formed as a single-piece construction, an integral construction, or a unified entity. In other words, the components can be integrally formed, which means connected together to form a single complete workpiece or unit, or so as to be together as a single complete workpiece or unit, and cannot be easily disassembled without destroying the integrity of the workpiece or unit.

[0070] Therefore, applicants should be understood to require at least: i) each filter cleaning device disclosed and described herein, ii) the related methods disclosed and described, iii) analogs, equivalents, and even implicit variations of each of these devices and methods, iv) those alternative embodiments that achieve each function shown, disclosed or described, v) those alternative designs and methods that achieve each function shown, such as implicitly achieving the functions disclosed and described, vi) each feature, component and step shown as a separate and independent utility model, vii) applications enhanced by the various systems or components disclosed, viii) the resulting products produced by such systems or components, ix) methods and devices substantially as described above and with reference to any attached examples, x) various combinations and permutations of each previous element disclosed.
