Definitions

  • the invention relates generally to air cleaner housing systems.
  • it relates to devices and methods for attaching an air cleaner tube to the air cleaner housing to facilitate introducing dirty air into or removing clean air from the air cleaner housing.
  • Air cleaner housings are typically arranged to support one or more air filter elements within and two or more air cleaner tubes attached thereto to bring dirty air into the air cleaner housing and to carry clean air out of the air cleaner housing.
  • the air cleaner tubes are also connected to various components such as an intake manifold in the case of clean air in an air cleaner housing for motor vehicles.
  • an air cleaner housing In order for an air cleaner housing to be effective, it should provide an adequate seal between various components within the housing to prevent air from leaking around the air filter element(s) to the clean air side without first passing through the air filter element(s).
  • some sort of access port should be provided on the housing to permit replacement of the air filter elements.
  • air cleaner housings are available in a variety of shapes and configurations. Many provide a separate access location to facilitate replacement of an air filter element within the housing.
  • the housing may comprise two shells in which the top shell is removable to provide access to the air filter element disposed on the bottom shell.
  • Such configuration requires even tensioning of the two shells along its entire periphery edge in order to provide an adequate seal; hence, many fasteners are needed around the periphery of the shells and a significant amount of time and manual dexterity is required to properly loosen and tighten these fasteners.
  • Other air cleaner housings provide openings for attaching air cleaner tubes to the housing.
  • an air cleaner housing system that is capable of providing relatively easy access to replace air filter elements disposed within the housing, an inexpensive and easy to operate attachment device for attaching the air cleaner tube to the housing, the ability to attach and detach the air cleaner tube repeatedly as desired, and providing adequate seal(s) between the various components within the housing to prevent air from leaking around to the clean air side without first passing through the air filter element.
  • One embodiment of the invention relates to an air cleaner system having an air cleaner tube extending along a central axis and an air cleaner housing including an aperture, wherein the aperture size and shape is configured to receive one end of the air cleaner tube.
  • the air cleaner system further includes a twist fit connector having a first portion disposed around the air cleaner tube and a second portion positioned on the air cleaner housing, wherein the first portion includes a first plurality of spaced-apart flanges cincturing a substantially circular first edge thereof and the second portion includes a second plurality of spaced-apart flanges cincturing a corresponding substantially circular first edge thereof.
  • Another embodiment of the invention relates to an air cleaner having an air cleaner tube extending along a central axis, an air cleaner tube having an opening to partially receive the air cleaner tube, and a removable air filter disposed inside the air cleaner box.
  • the air cleaner further includes a first portion of a twist fit connector disposed around the air cleaner tube, having a first plurality of spaced-apart flanges and a locking element, and a second portion of the twist fit connector disposed on the air cleaner box, having a second plurality of spaced-apart flanges and a receiving element, wherein the twist fit connector moves between a first position to hold the air cleaner box and tube together and a second position to detach the air cleaner tube from the air cleaner box.
  • the air cleaner still further includes a first seal disposed between the air filter and the air cleaner tube, whereby dirty air passes through the air filter before exiting the air cleaner box when the twist fit connector is in the first position.
  • Still another embodiment of the invention relates to a method of assembling an air cleaner comprising inserting one end of an air cleaner tube into an opening of an air cleaner housing, aligning a locking element and a receiving element along a central axis, inserting a first plurality of flanges encircling the air cleaner tube in between the corresponding spaces between a second plurality of flanges disposed on the air cleaner housing, contacting the locking and receiving elements, and rotating the locking element relative to the receiving element around the central axis till further rotation in either direction is prevented by the locking element abutting a section of the receiving element.
  • an air cleaner housing system 10 including an air cleaner housing 12, an air cleaner tube 14, an air filter element 16, a first portion 18 of an attachment mechanism of the radial-type twist fit connector, a second portion 20 of the attachment mechanism, and a first seal 36.
  • Air cleaner housing 12 also referred to as an air cleaner container or box, includes an aperture 22 on a side of the air cleaner housing 12 for partially receiving the air cleaner tube 14.
  • Aperture 22 is substantially circular in shape and of a sufficient diameter to accommodate the air cleaner tube 14.
  • Aperture 22 may also serve as an access point for replacing the air filter element 16 housed within the air cleaner housing 12.
  • air cleaner housing 12 can include multiple apertures to accommodate multiple air cleaner tubes or provide a separate access point, e.g., a door, for filter replacements (not shown).
  • the air cleaner housing 12 can be fabricated in a variety of shapes and materials.
  • air cleaner housing 12 can be a parallelepiped formed from a plastic-type material.
  • Air filter element 16 fits through aperture 22 and resides inside air cleaner housing 12.
  • Air filter element 16 is preferably an elongate radial flow air filter axially extending along a central axis running through air cleaner housing 12.
  • air filter element 16 comprises an outer circumference and a hollow inner circumference, in which the diameter of the inner circumference is large enough to accommodate the air cleaner tube 14 (see FIG. 2).
  • the outer circumference of air filter element 16 could be larger than the diameter of aperture 22.
  • air filter element 16 is typically a disposable air filter comprised of a zigzagged paper or synthetic air cleaning medium that removes particulate matter from air as it passes through the cleaning medium.
  • Air cleaner tube 14 includes an end 15 having a substantially circular cross-section for snuggly fitting inside the hollow inner circumference of air filter element 16. It should be understood that the rest of the air cleaner tube 14 may differ in shape and/or size along the rest of its length relative to end 15 of air cleaner tube 14 (not shown).
  • First and second portions 18, 20 collectively comprise the attachment mechanism which attaches the air cleaner tube 14 to the air cleaner housing 12.
  • the first plurality of flanges 22 are disposed around a first edge of the first portion 18, in which the first edge is parallel and proximate to end 15 of the air cleaner tube 14.
  • Each of the first plurality of flanges 22 are equally spaced apart from each other and extend or radiate in an outward direction.
  • a minimum of three flanges will comprise the first plurality of flanges 22.
  • the second plurality of flanges 28 are disposed around a first edge of the second portion 20.
  • Each of the second plurality of flanges 28 is also equally spaced apart from each other but extend or radiate in an inward direction.
  • a minimum of three flanges will similarly comprise the second plurality of flanges 28. Therefore, when the first plurality of flanges 22 are positioned at aperture 22, the first plurality of flanges 22 can be inserted in the spaces between the second plurality of flanges 28.
  • Cover plate 26 is disposed on a second edge of first portion 18, in which the second edge is parallel to end 15 and is further away from end 15 then the first edge of first portion 18.
  • Radial locking element 24 is disposed on the outer diameter of cover plate 26. Radial locking element 24 faces radially inward and is preferably a stepped cantilever snap element. Moreover, the radial locking element 24 is preferably comprised of a semi-flexible material, such as a plastic-type material, to facilitate attaching and detaching the air cleaner tube 14 to and from the air cleaner housing 12.
  • Radial receiving element 30 is disposed on a second edge of the second portion 20. Radial receiving element 30 faces radially outward to correspondingly engage the radially inward facing radial locking element 24. Radial receiving element 30 preferably comprises a ramped element 32 and a stop element 34.
  • first seal 36 can be attached around the inner circumference of air filter element 16 or it can cincture the outer circumference of end 15 of the air cleaner tube 14. First seal 36 prevents dirty air from bypassing the air filter element 16 and inadvertently entering the clean air side of the air cleaner housing system.
  • first seal 36 is an O-ring.
  • the attachment mechanism moves between a first rotational position, in which the air cleaner tube 14 is fully attached to the air cleaner housing 12, and a second rotational position, in which the air cleaner tube 14 is detachable from the air cleaner housing 12.
  • first rotational position end 15 of air cleaner tube 14 is inserted through aperture 22 into the air cleaner housing 12.
  • the radial locking element 24 is then aligned with the radial receiving element 30 relative to the central axis extending along the air cleaner tube 14 and through the center of aperture 22 such that the first plurality of flanges 22 fits in the spaces between the second plurality of flanges 28.
  • end 15 is in contact with the first seal 36 and the first plurality of flanges 22 are in a plane behind the plane containing the second plurality of flanges 28 (see FIG. 2). The attachment is completed, as shown in FIG.
  • Air cleaner tube 14 is also secured against axial movement, i.e., being pulled out of the air cleaner housing 12, by the second plurality of flanges 28.
  • the radial locking element 24 is pulled radially away from the radial receiving element 30 to disengage the attachment mechanism so that counter-clockwise rotation of the first portion 18 can commence.
  • air cleaner tube 14 can be detached from the air cleaner housing 12.
  • FIGs. 4 and 5 illustrates an alternate embodiment of the air cleaner housing system 10.
  • Air cleaner housing system 50 is similar to system 10 except that system 50 embodies an attachment mechanism of the axial-type twist fit connector.
  • the attachment mechanism comprises a first portion 58, which includes a first plurality of flanges 62, an axial locking element 64, and a cover plate 66, and a second portion 60, which includes a second plurality of flanges 68 and an axial receiving element 70.
  • the axial locking element 64 faces toward the air cleaner housing 12 and is flexible in the axial direction.
  • the axial receiving element comprises a ramped element 72 and a stop element 74 in which both face toward the air cleaner tube 14.
  • the second portion 60 can be integrally molded as part of the air cleaner housing 12.
  • the axial locking element 64 bends in the axial direction as it engages and moves along the ramped element 72 and abuts the stop element 74.
  • the axial locking element 64 is pulled in the axial direction away from the axial receiving element 70 and then rotated in the counter-clockwise direction to detach the air cleaner tube 14.
  • each of the first plurality of flanges 22 could include an angled end, as shown in FIG. 2, to further prevent undesirable detachment of the air cleaner tube 14 when in the first rotational position.
  • FIG. 6 shows a second seal 70 disposed between the first and second portions 58, 60 to provide an axial air tight seal at the connection interface thereof.
  • FIG. 7 shows a second seal 72 disposed between the first and second portions 18, 20 to provide a radial air tight seal at the connection interface thereof.
  • second seals 70, 72 each comprises an O-ring.
  • the first plurality of flanges 22 could be inwardly radiating flanges while the second plurality of flanges 28 could be outwardly radiating flanges.
  • first and second portions 18, 20 may be integrally molded with the air cleaner tube 14 and housing 12, respectively, to minimize fabrication costs and breakage of subcomponents.
  • the attachment mechanism could be configured to require counter-clockwise rotation to achieve the first rotational position and clockwise rotation to achieve the second rotational position.
  • the air filter element 16 may be attached to the air cleaner tube 14 such that they move together as one unit. In this case the first seal 36 could be omitted as well as the apparatus for holding the air filter element 16 in place inside the air cleaner housing 12.
