Technical field

[0002] The present invention relates to filter structures generally intended for use in filtering air, such as intake air for internal combustion engines, and more particularly relates to filter assemblies that contain a plurality of components located in a housing to provide the desired filter performance. capabilities.

Prerequisites for creating the invention

[0003] Filtration of air or other gas is desirable in a number of systems. Its typical application is the filtration of air drawn into internal combustion engines. Another application is filtration using crankcase ventilation filter units. Typically, such systems contain filter units that contain a serviceable filter cartridge. After some period of use, the filter pack in the filter housing requires maintenance in the form of either cleaning or complete replacement. Typically, in the case of an air cleaner or crankcase ventilation filter assembly used in conjunction with an internal combustion engine, such as in a vehicle, the filter media is contained in a removable and replaceable, i.e. serviceable component, usually called a filter element or cartridge. The filter cartridge is designed for sealed installation and can be removed inside the air purifier during use. Improvements are needed in filter designs regarding assembly, serviceability and/or use. The filter cartridge may be provided as a first (eg, main) filter cartridge or a second (eg, auxiliary or protective) filter cartridge. The air cleaning assembly may include only the first filter cartridge or both the first filter cartridge and the second filter cartridge.

The essence of the invention

[0004] An air purifying assembly is described. In one aspect, the air cleaning assembly includes a housing defining an inlet and an outlet and including an access opening between the inlet and the outlet. The air cleaner also contains a filter cartridge that is housed in the housing and covers the access opening. The air cleaner also contains a locking mechanism. The locking mechanism is configured to move between an unlocked position in which the filter cartridge can be installed and removed from the housing, and a locked position in which the filter cartridge is secured within the housing. The filter cartridge and locking mechanism contain cooperating parts that allow the locking mechanism to move from an unlocked position to a locked position only when the filter cartridge is installed in the housing.

Detailed description

[0001] Exemplary filter assemblies, filter cartridges, features and components thereof are described and presented herein. Many specific features and components are described in detail. Many of them can be applied to provide an advantage. However, there is no specific requirement that various individual features and components be used in an overall assembly with all of the described features and characteristics to provide any benefit according to the present invention.

[0002] It should be noted that many embodiments are presented and described. The embodiments are not intended to be exclusive of the features presented. That is, if necessary, selected features of one embodiment can be applied in one or more other embodiments to obtain an advantage. In many examples, the illustrated filter assembly is an air cleaning assembly, such as that used to filter intake air for an internal combustion engine.

Additional applications are possible, for example, applications in which the filter assembly is a crankcase ventilation filter assembly in which a filter cartridge is used to filter escaping gases into the crankcase, which typically contain both particulate and liquid contaminants. Both types of filter assemblies are typically "gas filter assemblies" because the transported part being filtered is gas (air or gases from the crankcase ventilation system). Although the techniques described herein will typically be used in connection with gas filtration, they can be used to filter other materials, such as liquids, if necessary.

General design of the air cleaner

[0134] In FIG. 1-9 show aspects of the air purifier 10 in accordance with an embodiment of the present invention.

The air purifier 10 includes a housing assembly 12 with a main housing portion 20 defining an internal portion 20a in which the main removable filter cartridge 100 is located. The housing assembly 12 further includes an outlet assembly 40 that is configured to discharge filtered air. In the illustrated embodiment, the air release assembly 40 defines an internal portion 40a in which the auxiliary removable filter cartridge 200 is located. The release assembly 40 may be configured separately from and attached to the main housing portion 20, or it may be configured as an integral part of the main housing portion 20. The housing assembly 12 further includes an inlet assembly 50 through which air to be filtered enters the assembly 10. The inlet assembly 50 may be configured separately from and attached to the main housing body 20, or it may be configured as an integral part of the housing 20. In the described embodiment and as described in detail later in this section, the housing assembly 12 has a modular configuration in which the exhaust and inlet assemblies 40, 50 are separate units attached to the main housing body 20.

[0135] The air purifier 10 may include an access cover 125 for providing access to an interior portion 20a of the body body 20, such as for positioning and removing the filter cartridges 100, 200. The access cover 125 may be a separate component or may be an integral part of another component of the air filter cartridge 100, such as integral with the surrounding shell of the filter cartridge 100. In the embodiment described herein, the access cover 125 is integrally formed with the air filter cartridge 100. In one aspect of the present invention, the access cover 125 and thus the filter cartridge 100 are secured to the body body 20 via a pair of connectors or locking mechanisms 90.

[0136] In one aspect, the air filter cartridge 100 may be configured such that it has an axis of symmetry with respect to a plane passing through the longitudinal axis of the air filter cartridge 100. Such a configuration may allow the air filter cartridge 100 to be installed in any direction and still interact in an acceptable manner with the mating portions of the main housing body 20 and locking mechanisms 90.

Main part of corps 20

[0137] In FIG. 10-13, the body body 20 is shown separately. As shown, the body body 20 is formed as a single piece made of a polymeric material such as nylon, polypropylene, or ABS plastic. In one aspect, the body body 20 extends between the first end 20a and the second end 20b and defines an inner portion 20i. The main housing portion 20 can be characterized as having a central portion 22, an inlet portion 24, and an outlet portion 26. Although the terms "inlet portion" and "outlet portion" are used herein, it should be understood that, due to the configuration of the main housing portion 20 , the inlet portion 24 may function as an outlet end of the body main body 20, and the outlet portion 26 may function as an inlet end of the body body 20. In general, the center portion 22 holds the filter cartridge 100, the inlet portion 24 attaches the air inlet assembly 50 to the main housing portion 20 and also supports one of the locking mechanisms 90, and the outlet portion 26 attaches the air outlet assembly 40 to the main housing portion 20, and also supports another locking mechanism 90.

[0138] In one aspect, the central portion 22 of the main housing portion 20 is defined by a side wall 22a extending between a first end wall 22b located adjacent the inlet portion 24 and a second end wall 22c located adjacent the outlet portion 26. Each of the first and the second end walls 22b, 22c respectively define openings 22d, 22e through which air can flow through the body body 20. The central portion 22 further defines an access hole 22f through which the filter cartridge 100 can be installed. The access hole 22f is also sized such that the outlet assembly 40 and the inlet assembly 50 can be inserted through the access hole 22f during assembly of the housing assembly 12. In one aspect, the access hole 22f is provided with a channel structure defining an open channel 22g for placement a sealing member such as an O-ring so that the access cover 125 can be properly sealed against the body body 20. In fig. 106 and 107 show an alternative air cleaner design in which the access hole 22f has a variable profile with a transversely or radially cut portion 22f 1 that can be used to facilitate proper positioning of the filter cartridge 100 during insertion.

[0139] The inlet portion 24 of the body body 20 is shown provided with an annular side wall 24a of a rectangular shape with rounded ends or corners (eg, an elongated annular shape). A plurality of opposing and spaced openings 24b are provided in the side wall 24a. The openings 24b are designed to accommodate snap-type elements complementary to the shape of the air inlet assembly 50 to facilitate a snap-type connection between the body body 20 and the air inlet assembly 50. The inlet portion 24 is also provided with a mounting structure 24c located adjacent to the access hole 22f. The mounting structure 24c provides a structure on which the locking mechanism 90 can be mounted. As shown, the mounting structure 24c is formed by a pair of spaced apart parallel L-shaped channel or rib members 24d extending in the longitudinal direction of the body body 20. The inlet portion 24 is further provided with a cutout portion 24e in the side wall 24a to facilitate installation of the dust ejector in the desired location and orientation, as described later in this section.

[0140] The outlet portion 26 of the main body portion 20 is shown provided with an annular side wall 26a of a rectangular shape with rounded ends or corners (eg, an elongated annular shape). A plurality of opposing and spaced openings 26b are provided in the side wall 26a. The openings 26b are designed to receive snap members complementary to the shape of the air release assembly 40 to help provide a snap type connection between the body body 20 and the air release assembly 40. The outlet portion 26 is also provided with a mounting structure 26c located adjacent to the access hole 22f. The mounting structure 26c provides a structure on which the locking mechanism 90 can be mounted. As shown, the mounting structure 26c is formed by a pair of spaced apart parallel L-shaped channel or rib members 26d extending in the longitudinal direction of the body body 20. Although not shown, the outlet portion 26 may further be provided with a cutout portion similar to 24e in the side wall 26a to facilitate installation of the dust ejector in a desired position and orientation, the air cleaner being configured to allow air to flow from portion 26 to portion 24 .

Node 40 release

[0141] In FIG. 14-18 show the release assembly 40 in more detail. For clarity, the filter cartridge 200 is not shown installed in the release assembly in FIG. 14-18. As shown, the release assembly 40 includes a release body 42 and a flow limit indicator 44. The flow limit indicator 44 is a dial indicator that snaps into place in the release assembly 40 . As shown, the main release portion 42 is formed by a side wall 42a extending between the first end 42b and the second end 42c. In one aspect, the side wall 42a includes a raised portion 42d for receiving and sealing with a portion of the sealing element 204 associated with the auxiliary filter cartridge 200. The inner portion of the side wall 42a forms the remaining portion of the sealing surface contacting the sealing member 204 of the auxiliary filter cartridge. The side wall 42a is also shown provided with snap portions 42e, each of which has an inclined surface 42f and a stop surface 42g. The snap portions 42e engage with the openings 26b in the housing body 20 such that a snap connection can be formed between the housing assembly 20 and the release assembly 40.

[0142] The release unit 40 is also shown provided with a flange structure 46 adjacent the first end 42b of the side wall 42a of the main release portion. In one aspect, the flange structure 46 is formed by a first flange portion 46a and a second flange portion 46c, each of which extends radially outward from the side wall 42a. In one aspect, the flange portions 46a, 46c define a mounting surface 46b on one side of the flange structure 46 and a sealing surface 46c on the opposite side of the flange structure 46.

[0143] In the illustrated embodiment, the sealing surface 46 of the first flange portion 46a is located at an angle a1 to the longitudinal axis X of the air cleaner 10 and the exhaust assembly 40. In one aspect, angle a1 is an oblique or oblique angle. In the example shown, angle a1 is 95 degrees. However, other angles are possible, such as angles in the range of 90 to 135 degrees, such as 100 degrees. In some examples, the angle a1 is minimized, whereby the surface area of the side wall 42a between the flange portions 46a, 46c is likewise minimized, thereby reducing the likelihood of debris falling into the inner portion 20i accumulating on the resulting shoulder area of the side wall 42a , for example, when the filter cartridge 100 is removed. In one aspect, the first and second flange portions 46a, 46c are located at an angle a2 relative to each other. In the example shown, the angle a2 is greater than zero and less than 180 degrees, as a result of which the first and second flange portions 46a, 46c are not parallel to each other. In the example shown, angle a2 is approximately 152 degrees. At the location where the outlet end of the material package 110 is perpendicular to the longitudinal axis X, the angles a1 and a2 can also be considered oblique angles with respect to the outlet end 114. Since the sealing surfaces 132b, 132c of the sealing element 132 can be defined by the angles a1, a2 of the flange portions 46a, 46c , the sealing surfaces 132b, 132c may similarly have the angles specified above. Other angles possible.

[0144] When the release assembly 40 is inserted through the main body access opening 22f such that the release assembly 40 is located in the inner portion 20i of the main housing portion 20, the release assembly 40 can be pushed forward toward the outlet portion 26 (or inlet portion 24) of the main body. portion of the housing until the mounting surface 46b abuts the end wall 22 of the main housing portion 20. This position is best seen in the sectional views shown in FIG. 6A and 6B. The end wall 22c provides rigid support relative to the mounting surface 46b of the first flange portion 46a. During this operation, the inclined surface 42f of each of the snap portions 42e moves along the inner surface of the side wall 26a until the release main portion 42 is sufficiently inserted so that the snap portions 42e are completely inserted into the openings 26b. At this time, the abutment surfaces 42g of the snap portions 42e are locked against the edge of the openings 26b in the snap-type connection, and further movement of the release body 42 by the snap portions 42e and the end wall 22c is blocked.

[0145] In one aspect, the second flange portion 46c is adjacent to the first flange portion 46a to form a sealing surface 46d that is opposite the mounting surface 46b. The sealing surface 46d provides a surface against which a suitably shaped sealing member of the filter cartridge 100 can form a seal. Since the first flange portion 46a and the second flange portion 46c are not parallel to each other, the portion 46e of the sealing surface 46d defined by the first flange portion 46a is located at an angle a2 to the portion 46f of the sealing surface 46d defined by the second flange portion 46c. Accordingly, it is contemplated that the sealing surface 46d may have a complex shape or profile. At the location 46g of the sealing surface 46d, where the first and second sealing portions 46e, 46f are adjacent to each other, the sealing surface 46d is curved so that a smooth transition is formed. In other words, the first and second sealing portions 46e, 46f are flat, and the curved portion 46g connects the portions 46e, 46f. In some examples, all or a portion of the sealing surface 46d is curved rather than flat. For example, either or both of the first and second sealing portions 46e, 46f may be curved rather than flat. In the example shown, the first sealing portion 46e is less than half of the entire sealing surface 46d, and thus its length is less than the length of the second sealing portion 46f.

[0146] The outlet assembly 40 is also provided with an outlet end 48 defined by an end wall 48a and an outlet tube 48b to which a hose or conduit may be connected. The outlet end 48 is also shown to include inner side walls or ribs 48c for engagement with the filter cartridge 200. The outlet end 48 is further shown to also include a side wall or receptacle 48d for receiving the restriction indicator 44.

[0147] One of the advantages of the presented configuration associated with the disclosed modular design is that variously configured release assemblies 40 can be installed on the body body 20 to suit any specific application. For example, the outlet assembly may be provided with a different size or shape of outlet tube or conduit, may be provided without a restriction indicator, or may be provided with additional ports for mounting electronic sensors. Accordingly, the present invention is not limited to the specific release assembly configuration described herein, since other or different parts may be included therein.

Inlet unit 50

[0148] In FIG. 19-31 show aspects of the intake assembly 50 in more detail. As shown, the inlet assembly 50 includes an inlet main portion 52, a pre-cleaning assembly 60, and a dust ejector assembly 66. In one aspect, the pre-cleaning assembly 60 is generally used to remove selected material or contaminants carried by the air flow into the air cleaning assembly 10 before the air reaches the filter cartridge 100 located therein. The pre-cleaner 60 generally includes a side wall 62a defining an end wall 62b through which a plurality of cyclone separator tubes 64 extend. In the embodiment shown in the drawings, 42 separator tubes 64 are provided. More or fewer separator tubes 64 may be provided.

[0149] The main inlet portion 52 is also shown to include a side wall 52a that defines an end wall 52b. A plurality of receiving portions 54 are shown as being provided on and extending through the end wall 52b. The receiving portions 54 enter into the outlet openings of the separator tubes 64 when the pre-cleaning unit 60 is installed in the main intake portion 52, with the side wall 62a sliding within the side wall 52a. In the illustrated example, the pre-cleaner assembly 60 may be secured by a fastener 62c (eg, a threaded screw or bolt) extending into a threaded hole 52c in the end wall 52b of the inlet body 52.

[0150] In operation, contaminants are separated to the outer walls of the separator tubes 64 and collected in the internal space formed between the end walls 62b, 52b and the side wall 52a, and then removed from the nozzle of the dust ejector assembly 66. The relatively contaminant-free air passing through the central portions of the separator tubes 64 enters the receiving portions 54, where the air can pass through the end wall 52b and into the internal portion 20i, from which the air can enter the filter cartridge 100 for further cleaning.

[0151] As best shown in FIG. 19 and 23-21, the dust ejector assembly includes a dust ejector nozzle 67 mounted through an opening in the side wall 52a of the main inlet portion, and a retaining clip 68 securing the dust ejector nozzle 67 to the side wall 52a. Unlike conventional assemblies known in the art, in which the dust ejector nozzle is molded into a pre-cleaner assembly or part of the air cleaner body, the dust ejector assembly 66 disclosed herein is removable and can be installed in a variety of locations if the air cleaner 10 is provided with multiple openings. 52d. The inlet unit 50 is installed through the access hole 22f of the body body 20 in the same manner as the described installation of the inlet unit 40. The ability to remove the dust ejector assembly 66 simplifies the assembly process since insufficient clearance would have occurred if the dust ejector port 67 were not removable and assembly was attempted through the access hole 22f. After installing the inlet unit 50 on the main part 20, the dust ejector pipe 67 can be inserted into the hole 52d in the main inlet part 52.

[0152] As shown in FIG. 26-31, the dust ejector port 67 is defined by a tubular sidewall 67a that extends to a flange 67b. When the dust ejector pipe 67 is inserted into the inlet main body opening 52d in the direction from the outer side of the side wall 52a to the inner part defined by the side wall 52a, the flange 67b acts as a stop to prevent further insertion into the inner part. In one aspect, the flange 67b has a shape complementary to the profile of the side wall 52a such that the flange 67b and the side wall 52a are generally flush with each other. In the example shown, both the side wall 52a at the location of the hole 52d and the flange 67b are curved. However, if the mounting location of the dust ejector assembly 66 is along the flat side of the side wall 52a of the main inlet portion, the flange 67b may be planar or flat.

[0153] The dust ejector port 67 is further provided with a pair of retaining flanges or lugs 67c that extend through the main inlet portion opening 52d when the flange 67b abuts the side wall 52a. The holding flanges 67b are placed on the holding clamp 68, which includes a side wall 68a defining an opening 68b with a tapered opening region 68c for receiving the tapered neck portion of the tubular sidewall 67a between the flanges 67b, 67c of the dust ejector port 67. The tapered hole area 68c allows for snap-type fastening between the dust ejector pipe 67 and the holding clamp 68. After inserting the dust ejector pipe side wall 67a through the hole 52d, the holding clip 68 is installed on the ejector pipe side wall 67a to the side wall 52a of the main intake part. opposite the flange 67b (ie, on the inside of the side wall 52a). Once inserted, the retaining clip 68 abuts the retaining flanges 67b to prevent the dust ejector pipe 67 from being removed from the inlet body 52. As indicated in FIG. 28, the clamp 68 has a width w1 at the distal end of the clamp, which increases to a width w2 towards the opposite end of the clamp 68 to form an inclined type structure. Thus, when the retaining clip 68 is inserted, the increased thickness of the clip 68 helps to hold the ejector pipe 67 in place, whereby the ejector pipe 67 is secured axially in place relative to the side wall 52a. A handle or edge member 68d is provided on the holding clip 68 to facilitate manipulation of the holding clip during insertion and removal.

[0154] Inclined members or sidewall ribs 68e may also be provided to engage the ends of the retaining flanges 67c to prevent the ejector port 67 from rotating relative to the sidewall 52a. Preventing rotation is advantageous because such rotation may cause the connection between the retaining clip 68 and the ejector port 67 to become loose.

[0155] In one aspect, the side wall 68a of the retaining clip is shaped to be complementary to the profile of the side wall 52a such that the side wall 68a and the side wall 52a are generally flush with each other. In the example shown, both the side wall 52a at the location of the hole 52d and the side wall 68a are curved. However, if the mounting location of the dust ejector assembly 66 is along a flat side of the side wall 52a of the main inlet portion, the side wall 68a may be planar or flat.

[0156] The side wall 52a of the main inlet portion 52 is also shown provided with snap portions 52e, each of which has an inclined surface 52f and a stop surface 52g. The snap portions 52e engage with the openings 24b in the housing body 20 such that a snap connection can be formed between the housing assembly 20 and the inlet assembly 50.

[0157] The inlet assembly 50 is also shown provided with a flange structure 56 adjacent to the second end 42 of the main outlet side wall 42a. In one aspect, the flange structure 56 is formed by a first flange portion 56a and a second flange portion 56c that extend radially outward from the side wall 52a. In one aspect, the flange portions 56a, 56c define a mounting surface 56b on one side of the flange structure 56 and a sealing surface 56c on the opposite side of the flange structure 56.

[0158] In the illustrated embodiment, the first flange portion 56a is located at an angle a3 to the longitudinal axis X of the air cleaner 10 and the inlet assembly 50. In one aspect, angle a3 is an oblique or oblique angle. In the example shown, angle a1 is 5 degrees. However, other angles are possible, such as angles in the range of 0 to 45 degrees, such as 10 degrees. In one aspect, the first and second flange portions 56a, 56c are located at an angle a4 relative to each other. In the example shown, the angle a4 is greater than zero and less than 180 degrees, as a result of which the first and second flange portions 56a, 56c are not parallel to each other. In the example shown, angle a4 is approximately 152 degrees. Other angles possible.

[0159] When the outlet assembly 40 is inserted through the main body access opening 22f such that the inlet assembly 50 is located in the inner portion 20i of the body body 20, the inlet assembly 50 can be pushed forward toward the inlet portion 24 (or inlet portion) of the main body. the housing until the mounting surface 56b abuts the end wall 22b of the housing main body 20. This position is best seen in the sectional views shown in FIG. 3A and 6A. The end wall 22b provides a rigid abutment relative to the mounting surface 56b of the first flange portion 56a. During this operation, the inclined surface 52f of each of the snap portions 52e moves along the inner surface of the side wall 24a until the inlet main portion 52 is sufficiently inserted so that the snap portions 52e are completely inserted into the openings 24b. At this time, the abutment surfaces 52g of the snap portions 52e are locked against the edge of the openings 24b in the snap-type connection, and further movement of the inlet body 52 by the snap portions 52e and the end wall 22b is blocked.

[0160] In one aspect, the flange structure 56 is adjacent to the first flange portion 56a to form a sealing surface 56d that is opposite the mounting surface 56b. The sealing surface 56d provides an axial surface against which a suitably shaped sealing member of the filter cartridge 100 can form a seal. Accordingly, the sealing surfaces of the sealing elements may have the same shape or profile, as described below for sealing surfaces herein. Since the first flange portion 56a and the second flange portion 56c are not parallel to each other, the portion 56e of the sealing surface 46d defined by the first flange portion 56a is located at an angle a4 to the portion 56f of the sealing surface 56d defined by the second flange portion 56c. Accordingly, it is contemplated that the sealing surface 56d may have a complex shape or profile. At the location 56g of the sealing surface 56d, where the first and second sealing portions 56e, 56f are adjacent to each other, the sealing surface 56d is curved so that a smooth transition is formed. In other words, the first and second sealing portions 56e, 56f are flat, and the curved portion 56g connects the portions 56e, 56f. In some examples, all or a portion of the sealing surface 56d is curved rather than flat. For example, either or both of the first and second sealing portions 56e, 56f may be curved rather than flat. In the example shown, the first sealing portion 56e is less than half of the entire sealing surface 56d, and thus its length is less than the length of the second sealing portion 56f.

[0161] One of the advantages of the presented configuration associated with the disclosed modular design is that variously configured inlet assemblies 50 can be installed on the body body 20 to suit any specific application. For example, an inlet assembly 50 may be provided without a precleaner, with an inlet manifold, a different precleaner design, and/or a dust ejector assembly. Accordingly, the present invention is not limited to the specific inlet assembly configuration described herein, since other or different parts may be included therein.

Filter cartridge 100

[0162] In FIG. 60-69 depict an exemplary embodiment of a filter cartridge 100 of an air purifying assembly 10. The filter cartridge 100 extends between a first end 102 and a second end 104. In one aspect, the first end 102 may be characterized as the upstream end of the filter cartridge 100 and the second end 104 may be characterized as the downstream end of the filter cartridge 100. The filter cartridge 100 may be considered the main or main filter cartridge and is used to selectively separate a desired amount of particulate or contaminant material.

[0163] The filter cartridge 100 is generally a serviceable part or removable component such that it can be periodically removed and replaced at will or as needed during the life of the air cleaner 10. Specifically, when the cartridge 100 becomes clogged or otherwise requires replacement, the access cover 125 is detached from the housing 20, and the clogged filter 100 is removed by pulling the access cover in the direction R1 away from the housing 20 by means of a handle 127 associated with the access cover 125. After such removal, another filter 100 can be placed in the housing 20 by inserting the filter cartridge 100 in the insertion direction I1. In one aspect, the directions I1 and R1 are perpendicular to the longitudinal axes X, X1 of the filter cartridge 100 and housing 20. In the example shown, the access cover 125 is integral with the filter cartridge 100 and thus acts as the previously described access cover 125 access. Likewise, the handle 127 is integrally formed with the access cover 125. In one aspect, the handle 127 has a length that is a majority of the length of the material package 110. As mentioned previously, FIG. 106 and 107 show a filter cartridge 100 in which the access opening 22f may have a variable profile with a cut-out portion 22f1. In such an embodiment, the access cover 125 may have a shape complementary to the shape of the access hole 22f, whereby the access cover 125 has a profiled shape with a protruding portion 125a that mates with or abuts the cut-out portion 22f1.

[0164] The filter cartridge 100 generally includes a material package 110, a shell 120 including integrally an access cover 125 and a handle 127, a first sealing element 130 at the inlet end of the material package 110, and a second sealing element 132 at the outlet end of the material package 110. The sealing elements 130, 132 are generally made of a relatively flexible material and may be referred to herein as a “flexible sealing element”, and may include an axial or radial sealing element. In one example, the sealing elements 130, 132 are in the form of injection molded gaskets. In the illustrated embodiment, the sealing elements 130, 132 are formed as gaskets with alternating segments of parallel edge seals 134 and open-edged pocket structures 136, as described later in this section. The sealing elements 130, 132 are shown separately in FIG. 75-77.

[0165] In the example shown, the material package 110 has an inlet end 112 for receiving unfiltered air or pre-cleaned air from a pre-cleaner (if present) and an outlet end 114 for delivering filtered air. The material package 110 is shown separately in FIG. 70. In the example shown, the material package 110 has a rectangular cross-sectional shape with rounded corners. However, other shapes are possible, such as round, oval and rectangular cross-sectional shapes. In one aspect, the material package 110 defines an outer perimeter 116 extending between the flow inlet and outlet ends 112, 114. In the example shown, the material pack 110 is made of a coiled material structure, for example, a material structure having a corrugated (typically corrugated) sheet of material and a sheet of liner material that together form parallel corrugations to form a corrugated or z-shaped filter material structure. Suitable material structures for the material stack 110 are described in more detail in the “Material Types and Configurations” section.

[0166] In one aspect, the shell 120 of the filter cartridge 100 is made of a polymeric material such as nylon, polypropylene, or ABS plastic. Shell 120 is shown separately in FIG. 66-69. In one aspect, the shell 120 defines a peripheral wall 122 that surrounds the outer perimeter 116 of the material package 110. The lattice structure 123 is also shown provided with a shell 120 to support the end 114 for discharging the flow of material package 110. The shell 120 may be attached to the material package 110 by means of an adhesive. The peripheral wall 122 may surround the entire outer perimeter 116 of the material package, as shown, or surround a portion of the outer perimeter 116 of the material package. As previously stated, the access cover 125 and the handle 127 are integrally formed with the shell. As shown, the access cover 125 includes a main body 125a that is sized and shaped to fit into and close the access hole 22f of the body body 20. The main body 125a defines a sealing surface 125b against which a seal associated with the body body 20 can form a seal. In the example shown, the handle 127 is provided with an access cover 125 such that there is an open space 127a between the handle 127 and the cover 125 to allow an operator to grasp the handle 127. The open space 127a may be formed as a recess under one or both sides of the handle 127, or it may be a completely open space, as shown in the graphics. In the example shown, the access cover 125 may be provided with signs 125c, such as text and directional arrows, to indicate to the operator the correct installation orientation of the filter cartridge 100.

[0167] In one aspect, the first and second seal support flanges 124, 126 extend perpendicularly from the peripheral wall 122. The seal support flanges 124, 126 respectively provide a support surface for the sealing elements 130, 132. The seal support flanges 124, 126 and supported by means of them, the sealing elements 130, 132 are respectively provided with profiles complementary to the sealing surface 46d of the outlet assembly and the sealing surface 56d of the inlet assembly. Accordingly, the seal support flange 124 defines a support surface 124a having a first portion 124b disposed at an angle a4 and a second portion 124c adjacent thereto, with an angle a4 defined between the first and second portions 124b, 124c. The shape of the support flange 124 imparts similar features to the sealing element 130, whereby the sealing surface 130a of the sealing element 130 has a first portion 130b positioned at an angle a3 and an adjacent second portion 130c positioned at an angle a4 relative to the first portion 130b. In the example shown, the material stack flow inlet end 112 is shown to be perpendicular to the longitudinal axis X1 of the filter cartridge 100. Accordingly, the first support flange portion 124a and the first seal portion 13 0b may be considered to form an angle a5 with the flow inlet end defining plane P1, which is equal to the angle a3 minus 90 degrees. Thus, angle a5 in the example shown is 10 degrees.

[0168] The seal support flange 126 defines a support surface 126a having a first portion 126b positioned at an angle a1 and an adjacent second portion 124 c positioned at an angle a2 relative to the first portion 126b. The shape of the support flange 126 imparts similar features to the sealing element 132, whereby the sealing surface 132a of the sealing element 132 has a first portion 132b positioned at an angle a1 and an adjacent second portion 132c positioned at an angle a2 relative to the first portion 132b. In the example shown, the material stack flow discharge end 114 is shown to be perpendicular to the longitudinal axis X1 of the filter cartridge 100. Accordingly, the first support flange portion 126a and the first seal portion 132b may be considered to form an angle a6 with the flow inlet end defining plane P2, which is equal to the angle a1 minus 90 degrees. Thus, angle a6 in the example shown is 10 degrees. In one aspect, the sealing surfaces 130a, 132a may be characterized as axial sealing surfaces or axially facing sealing surfaces because the end of the sealing surface is more perpendicular than not to the longitudinal axis X1 (i.e., more parallel than not to the ends material package 110, or facing the same general direction as the end of the material package) of the filter cartridge 100.

[0169] The sealing elements 130, 132 may be provided with various features to improve sealing. The sealing elements 130, 132 are shown separately in FIG. 61A-61C respectively. In fig. 61B shows a cross-sectional view of the sealing elements 130, 132. In one aspect, the sealing elements 130, 132 are injection molded seals. As shown, the sealing elements 130, 132 comprise a base element 133a and a pair of sealing lips or extensions 133b, 133c that together form a C-channel shape. The base member 133a and the side 133d of the edge extension 133b contact the flanges 124, 126 to support the seal and can be attached to the flanges 124, 126 by means of an adhesive. The sealing elements 130, 132 may also include a top segment 133e, with the C-shaped channel oriented at a 90 degree angle to the rest of the sealing element 130, 132. At the top segment 133e, the open side of the channel faces the same direction as the edge extension 133c the remaining segment of the sealing element 130, 132. This configuration allows for simplified molding of the sealing elements 130, 132 on the housing inlet and outlet assemblies 40, 50. At the location of the upper segment 133e, the distal ends of each of the edge extensions 133b, 133c form an axial sealing surface for the sealing elements 130, 132.

[0170] In one aspect, the first sealing surface portions 130b, 132b form an angle with each other defined by angles a1 and a3. As shown, this angle is approximately 20 degrees. In one aspect, the second sealing surface portions 130c, 132c form an angle with each other defined by angles a1, a2, a3 and a4. As shown, this angle is approximately 65 degrees. Other angles possible. In some examples, the first portions 130b, 132b are flat, and in others, the first portions 130b, 132b are curved. In some examples, the second portions 130c, 132c are flat, and in others, the second portions 130c, 132c are curved. In some examples, each of the first portions 130b, 132b and the second portions 130c, 132c is flat with a curved or radius portion connecting the first and second portions to each other. In some examples, the first portions 130b, 132b are flat and the second portions 130c, 132c are curved. In some examples, the first portions 130b, 132b define the majority of the length of the sealing surfaces, and the second portions 130c, 132c define a lesser portion of the length of the sealing surfaces.

[0171] As a result of placing the sealing elements 130, 132 at angles a5, a6, the sealing elements 130, 132 taper towards each other in the direction I1 of the insert and in the direction away from the cover 125, as a result of which the sealing elements 130, 132 are closer to each other at a location away from the cover 125 compared to a location adjacent to the cover 125 (ie, the distance between the sealing elements 130, 132 increases towards the cover). This tapered configuration allows for easier installation of the filter cartridge 100 into the interior portion 20i of the body body 20 with less compression resistance from the sealing members 130, 132 compared to a configuration in which the sealing members 130, 132 are oriented completely parallel to each other and to the plane. P without taper. This advantage is further achieved by the additional increased taper angle provided by the second portions 130c, 132c, which deviates outward from the plane defined by the first portions 130b, 132b (i.e., the distance between the seals on the second portions 130c, 132c increases in larger increments than the distance between the seals on the first parts 130b, 132b towards the cover). These parts allow the filter cartridge 100 to simultaneously have axial seals and yet be laterally or laterally loaded in the insertion direction I1, with the seals 130, 132 forming a seal with the housing 20 without the additional need for the filter cartridge 100 to move in the body body 20 along axis X1 to form a seal with housing 20.

[0172] Another advantage of the disclosed configuration is that the filter cartridge is sealed against the housing inlet and outlet assemblies 40, 50 rather than to the body body 20. Since the sealing element 130 forms a seal with respect to the sealing surface 56d of the housing inlet assembly 50, and the sealing element 132 forms a seal with respect to the sealing surface 46d of the housing outlet assembly 40, the lid 125 should not form a tight seal with the body body 20 or the filter cartridge 100 should not form a tight seal. seal with the main part 20 of the housing.

[0173] In one aspect, the filter cartridge 100 is also shown provided with locking mechanism engagement parts 150 at each end. The locking mechanism engagement members 150 interact with the locking mechanisms 90 so that the filter cartridge 100 can be locked in place relative to the housing 20. As shown, the locking mechanism engagement members 150 include an arcuate rib structure 152 and a pair of tongue-shaped structures 154, each of which is formed as a single unit with a cover 125 for access. The design and function of these parts are described in more detail in the Locking Mechanism section.

Filter cartridge 200 [0174] As shown in FIG. 1A, the exemplary air purifying assembly 10 includes an optional auxiliary or protective filter cartridge 200. The protective filter cartridge 200 is shown separately in FIG. 71-74. The safety filter 200 may generally be located between the main filter cartridge 100 and the outlet 48b of the housing 20. In a typical arrangement, the safety filter 200 is removably located in the air cleaning assembly 10 and is also generally considered a serviceable component that can be removed and replaced at will. and/or if necessary.

[0175] An exemplary embodiment of the protective filter 200 includes an outer frame 202 that carries a sealing member 204 having a pair of parallel edge seals and that generally matches in size and shape to the interior region of the body release body 42 (e.g., straight segmented portions 42d together with the straight sides of the inner surface of the side wall 42a) and may be sealed against the main release portion 42, preferably without gaps. Thus, the protective filter 200 can be pressed into the housing with a friction fit against the housing wall such that air cannot reach the outlet without first passing through the protective filter. The protective filter 200 may also include a filtration material 220, such as a pleated material. A handle 206 may also be provided to assist in installing and removing the filter cartridge 200 from the housing 20 via the access hole 22f.

Material Types and Configurations

[0176] Any type of filter material can be used as a material package for filter cartridges 100, 200 in accordance with embodiments of the present invention. For example, woven and nonwoven materials that use natural and/or synthetic fibers can be used to form grooved, pleated, and depth-defined filter media. An exemplary configuration includes a grooved filter material, such as a z-shaped filter design. The term "z-filter design" as used herein means a type of filter design in which individual pleated, folded or otherwise formed filter flutes are used to form sets of longitudinal, typically parallel, inlet and outlet filter flutes for fluid flow, passing through the material; the fluid flows along the length of the grooves between the opposite inlet and outlet ends (or flow ends) of the material. Some examples of filter material are presented in US Pat. No. 5,820,646; 5772883; 5902364; 5792247; 5895574; 6210469; 6190432; 6350296; 6179890; 6235195; D399944; D428128; D396098; D398046 and D437401, each of which is incorporated herein by reference.

[0177] One type of z-shaped filter media uses two special media components bonded together to form the material structure. The two components include a sheet of corrugated (usually corrugated) material and a sheet of facing material. The sheet of facing material is typically not corrugated, however it may also be corrugated (eg, perpendicular to the direction of the corrugation), as described in US Provisional Application No. 60/543804, filed February 11, 2004 and published as International August 25, 2005 PCT application WO 05/077487, which is incorporated herein by reference.

[0178] A sheet of corrugated material and a sheet of facing material are used together to form a material having parallel inlet and outlet corrugations. In some cases, the corrugated sheet and the liner sheet are bonded to each other and then coiled into a strip of material to form a z-shaped structure of the filter material. Such designs are described, for example, in US Pat. No. 6,235,195 and US Pat. No. 6,179,890, each of which is incorporated herein by reference.

[0179] In some other designs, multiple non-coiled sections, or strips, of corrugated (usually corrugated) material bonded to a liner material are stacked together to create a filter structure.

[0180] Corrugated material is a special form of corrugated material, wherein the corrugated material includes individual grooves or ridges (eg, formed by corrugation or folding) extending across it. As used herein, the term “corrugated” refers to a structure in a material and is often used to refer to a corrugated structure resulting from the passage of material between two corrugated rolls (for example, passing into a gap or gap between two rolls, each of which contains surface features appropriate to create corrugations in the resulting material).

[0181] Serviceable filter element or filter cartridge configurations that use z-shaped filter media are sometimes referred to as "straight-through configurations" or variations thereof. In general, serviceable filter elements or filter cartridges have a flow inlet end (or end) and an opposing flow outlet end (or end), with flow entering and exiting the filter cartridge generally in the same co-current direction. The term "serviceable" as used herein is meant to refer to a filter cartridge containing material that is periodically removed from the associated fluid (eg, air) purifier and replaced.

Locking mechanism 90

[0182] In FIG. 1 to 3, it can be seen that connectors 90, hereinafter referred to as locking mechanisms 90, are provided at each end of the filter cartridge 100. As described above, the filter cartridge 100 includes parts 150 comprising arcuate ribs 152 and tongue-like structures 154 that are integrally formed with a cover 125 for accessing the shell 120. Each of the tongues 154 fits into a corresponding recess 92a of the actuator portion 92 of the locking mechanism 90. The filter cartridge 100 cannot be fully inserted into the housing 20 unless the locking mechanisms 90 are rotated to a fully unlocked position, causing the recesses 92a to align with the tabs 154.

[0183] In FIG. 39-45 the executive part 92 is shown in more detail. As shown, the actuating portion 92 includes the aforementioned recess 92a, a pair of handle-like portions 92b allowing the user to grasp and rotate the actuating portion 92, a cover portion 92c, a rod portion 92d extending from the closing portion 92c, a holding groove 92e formed in the shaft portion 92d, the arcuate rib portion 92f defining a groove or channel 92g between the rib portion 92f and the side wall portion 92h of the cover portion 92c, a pair of cut out areas 92i at which the rib portion 92f meets the 92h as a side wall, and a central step member 92j extending between the rib portion 92f and the side wall portion 92h. The side wall portion 92h is also shown to include insertion or ramp portions 92h at the ends of the side wall portion 92h to provide improved rotation of the cover portion 92c over the filter cartridge access cover 125.

[0184] In FIG. 46-52, the base portion 94 of the locking mechanism 90 is shown in more detail. As shown, the base portion 94 includes a main portion 94a in which a central opening 94b is formed, a retaining spring retaining member 94c including a pair of openings 94f, a pair of openings 94g and a central tab 94h, a pair of arcuate rib portions 94d, and a pair of fasteners. 94e for attaching the locking mechanism 90 to the housing 20. In one aspect, the fasteners 94e include a pair of L-shaped channels 94e that receive correspondingly shaped L-shaped rib members 24d, 26d on the body body 20.

[0185] In FIG. 53-55, the locking spring 96 of the locking mechanism 90 is shown in more detail. As shown, the locking spring 96 extends from the base portion 96a to the inclined portions 96b, which in turn extend to the tongue portions 96c. The locking spring 96 further includes a latch portion 96d projecting from the tongue portion 96c. The latch portion 96d includes a latch surface 96e for engaging an edge 92m of the closure portion 92. The lock spring 96 is also shown configured with tabs 96e and 96f for attaching the lock spring 96 to the lock spring retaining member 94c of the base portion 94. In the example shown, the lock spring 96 is cut out from a sheet of steel (such as spring steel) and bent to the desired shape.

[0186] In FIG. 56-59, the retaining ring 98 of the locking mechanism 90 is shown in more detail. The holding ring 98 includes a main part 98a in which a central opening 98b is formed. In the example shown, the retaining ring 92 is made of a metal such as spring steel.

[0187] In one aspect, the lock spring base portion 94a is included in the lock spring retaining member 94c such that the tabs 96e extend through the holes 94f and 94g, and the tongue 96f is held by the central tongue 94h of the base portion 94a, whereby the inclined portions 96b extend into side away from the main portion 94a of the base portion. In fig. 36 shows a detent spring 96 attached to the base portion 94 when the cover 92 is removed to better show the connection between the detent spring 96 and the base portion 94. This configuration allows the detent spring tongue portion 96c to be deflected from a free or resting position (i.e., e. raised position in the graphics), shown as position P1 in FIG. 6E and 32-36, to a tilted position (ie, a lowered position in the graphics) to the main body 94a, shown as position P2 in FIG. 78. The actuating part 92 is mounted on the base part 94 by passing the rod part 92d of the actuating part 92 through the central opening 94b of the base part 94, whereby the closing part 92 from the actuating part covers the main part 94a of the base part. In this position, the rib portion 94d of the base portion 94 is located in the groove formed between the rib and the outer wall 92h of the actuating portion. The two parts are secured to each other by installing a retaining ring 98 onto a retaining groove 92e.

[0188] Once the actuator and base portions 92, 94 are attached to each other, the actuator portion 92 can be rotated relative to the base portion 94 from an unlocked position to a locked position. In the unlocked position, the actuating portion 92 is aligned such that the tongue portion 96c fits into the recess 92a in the closing portion 92c of the actuating portion 92, and such that the latch surface 96f of the locking spring 96 is pressed against the side edge 92m of the actuating portion 92. Due to the interaction between the latch surface 96f and the side edge 92m of the actuating part, the actuating part 92 cannot rotate and come out of the unlocked position when the locking spring 96 is in the resting position. In the event that the actuating portion 92 is rotated beyond this position and the filter cartridge 100 is not installed, the actuating portion 92 can be easily rotated back to the unlocked position since the inclined surface 96e allows the locking spring latching portion 96d to simply deflect and slide beyond the side edge 92f by executive part 92.

[0189] When the filter cartridge 100 is installed in the housing 20, the tabs 154 on the access cover 125 contact and deflect the detent spring 96 of each of the locking mechanisms 90 toward the base portion 94. This interaction is shown schematically in FIG. 6E by position P2. After the filter cartridge 100 is fully installed, each latch portion 96d moves beyond the side edge 92f, thereby allowing the actuating portion 92 to be rotated toward the locked position in either a clockwise or counterclockwise direction. When the actuating portion 92 is rotated toward the locked position, the rib portion 92f on the actuating portion 92 slides along the rib structure 152 of the filter cartridge 100. Thus, the rib structure 152, which can be characterized as a connecting member, works in conjunction with the actuator 92 to secure the material package within the air cleaner housing. Because the filter cartridge 100 is truly a side loading filter cartridge that does not need to be moved axially once inserted into the housing 20 to provide a seal, the filter cartridge 100 is configured such that at least a portion of the rib structure 152 extends axially beyond end limits for the inlet/outlet flow of the material package 110. In the specific example shown, the entire rib structure 152 extends axially beyond the inlet/outlet end of the material stack 110.

[0190] In the example shown, the locking mechanisms 90 do not directly provide a seal to the sealing elements 130, 132 in the longitudinal X-axis direction. Instead, the seal is formed by an interference fit between the individual sealing elements 130, 132 and the individual sealing surfaces 46d, 56d. The locking mechanisms 90 may be configured to apply a compressive force to the filter cartridge 100 and thus to the sealing elements 130, 132 in the insertion direction. The function of the locking mechanisms 90 is to lock the filter cartridge 100 in place in a self-centering manner, with tension being transferred between the locking mechanisms 90 and the cover 125, but without applying force to the sealing elements 130, 132. Thus, even in a configuration in which only one of the sealing elements 130, 132, the locking mechanisms 90 will still function to axially align and lock the filter cartridge 100 to provide a single seal without the need for a second seal or any other component on the cartridge or housing to provide the seal.

[0191] Additionally, the retaining ring 92 is configured to apply a resilient force to the actuator 92. The actuator 92 is rotated to a locked position until the actuator rib 92j engages the stop member or latch 152i on the structure 152 in in the form of an arcuate rib on the filter cartridge 100 that assists in holding the actuator 92 in the locked position and provides the installer with tactile feedback of the locked position. During the initial rotation of the actuator portion 92, the rib 92j rests on or abuts against the rib structure 152 on the filter cartridge 100, which provides little resistance to rotation. After the rib 92i reaches the anvil 152i, the rib 92i snaps into the recess formed by the anvil 152i, thereby simultaneously moving the actuator 92 to a locked position and providing tactile feedback. To remove the filter cartridge 100 from the housing, the operator simply rotates each actuator 92 until the recesses 92a are aligned with the tabs 154.

[0192] As can be understood from the above description, the complementary configuration of the locking mechanisms 90 and the filter cartridge tabs 154 ensures that the correct filter cartridge is installed in a housing that is actually designed to accommodate a given filter cartridge. If an attempt is made to install a filter cartridge without tabs 154, the filter cartridge 100 will not be able to move the locking mechanisms to the locked position, thereby alerting the installer to installing the incorrect filter cartridge. Although the tongues and recesses are shown as having a specific shape, other shapes are possible. Other shapes can be used for other air cleaner sizes or designs, thus ensuring the correct filter cartridges are installed in the correct housings across the entire product line.

Mounting fixture 30

[0193] In FIG. 78-93 show details of the mounting fixture 30 in more detail. The mounting fixture 30 is shown mounted on the main housing portion 20 in FIG. 1 and 3-8. As shown, the mounting fixture 30 includes a pair of mounting structures 32 that are mounted on the body body 20 spaced apart from and parallel to each other. The mounting fixture 30 is also shown to include four mounting clips 34. Any of the mounting clips 34 or the mounting structures 32 can be independently used to mount the air cleaner 10 to a support structure, with the mounting clips 34 providing a fixed distance mounting fixture and the mounting structures providing an adjustable mounting system. If both mounting structures 32 and mounting clamps 34 are provided, the installer or designer can use whichever mounting technique best suits the particular application. Since the mounting structures 32 and mounting clips 34 can be independently used to mount the air cleaner 10 to a support structure, the air cleaner 10 may be provided with only the mounting structures 32 or only the mounting clips 34.

[0194] As can be seen in FIG. 9 and 12, the body body 20 defines a pair of channels 25 defined by the side walls 25a that receive mounting structures 32. The body body 20 is also provided with end walls 25b extending across the side walls 25a at each end. The end walls 25b are also shown to include openings 25c such that the end walls can receive mounting clips 34. The mounting clips 34 form part of the mounting fixture. The body body 20 is also shown to include openings 25d for receiving a portion of the mounting structures 32 so that the mounting structures 32 can be attached to the body body 20.

[0195] In FIG. 78-91 show details of the mounting structures 32 in more detail. In one aspect, each mounting structure 32 includes a first channeling portion 32a that receives a second channeling portion 32b. As best seen in FIG. 82, the second channel portion 32b has a width or size that matches the head 32d of the bolt 32c, which allows the bolt to slide along the length of the second channel portion 32b but prevents rotation of the bolt. The first channel-forming part 32a has a central hole 32e through which the head 32d can pass, whereby the head can be placed in the second channel-forming part 32b. The first channel-forming part 32a further has lateral walls 32f that extend towards each other to secure the opposite side of the bolt head 32d. Thus, the bolt 32c may be placed in the first channeling portion 32a and then in the second channeling portion 32b such that the bolt 32c is slidably mounted between the second channeling portion 32b and the walls 32f. With this configuration, the position of the bolts 32c can be easily adjusted to align with said mounting structure. The bolts 32c from either end of the channel-forming portions 32a, 32b are prevented from slipping by the end walls 25b on the body body 20.

[0196] The second channel-forming portion 32b is shown to include an extension portion 32g at one end, which is disposed in the grooves 25d of the body body, and an extension portion 32h at the other end, which can engage or cooperate with the mounting clamp 34. The mounting structure 32 may also be provided with a spacer, liner, or countermeasure 32k (e.g., a compressed polymer tube or a half-moon shaped polymer tube) that may be positioned in the first and second channel portions 32a, 32b, which may assist in holding the bolts 32c in fixed position and dampen potential vibrations. In one aspect, the first channel portion 32a may be provided with openings 32f that receive tabs 32g of the second channel portion 32b to facilitate attachment of the first and second channel portions 32a, 32b to each other.

[0197] In FIG. 92-98 show the retaining clip 34 in more detail. In one aspect, the retaining clip 34 includes a base portion 34a, a head portion 34b extending from the base portion 34a, and a clamp portion 34c extending from the base portion 34a. The head portion 34b includes an opening 34d, which may be a threaded hole for receiving a mounting bolt. The mounting clamp 34 is mounted on the end wall 25b such that the head portion 34b extends through the opening 25c, whereby the end wall 25b is clamped between the base portion 34a and the clamping portion 34c. The holding clip 34 is further provided with a snap member 34e that snaps into the recess 25c when the clip 34 is installed such that the clip 34 is held on the end wall 25b by a snap-type connection. The clamping element 34 may also be provided with projections 34f that snap into recesses formed in the body body 20 to further secure the clamping element 34.

Positioning device 70

[0198] In FIG. 3A, 3B, 6B, 6C and 6D, it can be seen that the air cleaner 10 is provided with a positioning device 70 located in the recessed area 27 of the body body 20. In one aspect, the recessed area 27 is defined by a pair of side wall portions 27a and a side wall portion 27b. The parts 27a, 27b are part of the side wall 22a of the main body. The positioning device 70 is designed to ensure that the correct filter cartridge 100 is installed in the air cleaner 10. In one aspect, the positioning device creates an internal profile in the body body 20 that requires the filter cartridge 100 to have a corresponding profile of a complementary shape to be fully accommodated in the body body 20. In the illustrated embodiment, the positioning device 70 is formed by a pair of groups of spaced ribs 29b extending from the main body side wall 22a to the pin extensions 29a. In the example shown, five pins 29a and fins 29b are shown on each side of the inner body portion 20i. Each of the pins 29a and ribs 29b are configured to receive and hold the insert module 72. In the illustrated embodiment, three insert modules 72 are mounted on pins 29a and ribs 29b on each side of the body body 20. As will be understood, the positioner 70 is modular in nature and thus can be adapted to provide a number of different internal profiles to suit a particular application. For example, one, two, four, or all five insert modules 72 may be installed on each side. If less than five insert modules 72 are used, then the spacing between insert modules 72 can be adapted in a similar manner (for example, they can be located on every second pin 29a, etc.). In addition, the number and arrangement of the insert modules 72 may differ from one side of the body body 20 to the other. After selecting the desired number and arrangement of insert modules 72, the filter cartridge 100 can then be configured so that no part of the filter cartridge interferes with the inserts 72. An asymmetrical arrangement (side to side or front to back) can be selected to make it impossible for the cartridge to be inadvertently inserted. 100 of the filter in the reverse direction, thus ensuring that the properly selected filter is installed correctly.

[0199] In FIG. 6B shows an exemplary profile portion or extension 100a of a filter cartridge 100, wherein portions of the filter cartridge profile 100a extend between open spaces defined between insert modules 72, and wherein no portion of filter cartridge profile 100a extends into the space occupied by insert module 72. Thus, it is depicted that the filter cartridge 100 must have a profile generally corresponding to the profile 100a to be fully accommodated in the internal portion 20i of the body body 20 in the correct orientation. In the illustrated embodiment, the profile extension 100a is a protrusion formed integrally with the filter cartridge shell 120.

[0200] In FIG. 99-105a show an exemplary insert module 72 that includes a main body 72a, a recess 72b to receive a pin 29a, and a recess 72c to receive a rib 29b. The insert module 72b is also shown to include a profiled head 72d that can act as a counter surface for an incorrectly selected and/or installed filter cartridge 100. The insert module 72 may also be provided with a pin structure 72e located in the recess 72b, which may be placed in a corresponding hole 27c in the pins 29b.
