Assembly of magnet for oil filter case

Abstract

The present invention describes an assembly of magnets to be coupled to oil filter case to attract ferrous material. Oil filter case [20] takes the shape of a cylinder. Magnet [22] has two poles and one of the poles is coupled to the side of oil filter case [20]. A steel member [24] is provided to couple only the other pole of the magnet [22] with the oil filter case [20]. The steel member [24] comprises a pivot unit [26] that couples the pole of magnet, a pivot extender [28] which couples the pivot unit [26] and a bridge [30] that couples the pivot extender [28] with oil filter case [20]. The magnet assembly directs the magnetic field from outward pole towards the oil filter to create a pseudo horse shoe magnet effect.

Claims

1. A magnet system comprising: a magnet; a steel member; a band; a steel case; the magnet and the steel member each being magnetically attached to the steel case; the steel member rotatably contacting against the magnet; the steel member revolvably contacting against the steel case; the steel case being of cylindrical-shaped; the band comprising a first body member and a second body member; the first body member holding the magnet and the steel member; the second body member being adjustable in radius size with respect to the steel case; the magnet comprising a first pole and a second pole; the first pole and the second pole being located opposite to each other along the magnet; the first pole being one of a north pole and a south pole; the second pole being the other of the north pole and the south pole; the first pole being magnetically attached to the steel case; the second pole being magnetically attached to the steel member; the steel member comprising a pivot unit, a pivot extender and a bridge; the pivot extender being connected in between the pivot unit and the bridge; the pivot unit being magnetically attached to the second pole; the pivot unit rotatably contacting against the second pole; the bridge being magnetically attached to the steel case; the bridge revolvably contacting against the steel case; the bridge being separate from the magnet via the pivot extender; in response to the first pole being magnetically attached to the steel case, and in response to the pivot unit rotatably contacting against the second pole, the bridge revolvably contacting against the steel case around the magnet; and in response to the first pole and the bridge each being magnetically attached to the steel case, and in response to the pivot unit being magnetically attached to the second pole, a pseudo horse shoe magnet effect being created by a magnetic field path being directed from the second pole through the pivot unit, the pivot extender and the bridge to the steel case.

Description

BRIEF DESCRIPTION OF DRAWINGS

(1) The present invention will now be described in greater detail, by way of an example, with reference to the accompanying drawing, in which:

(2) FIG. 1 illustrates a magnet and steel member, according to an embodiment of the invention.

(3) FIG. 2 illustrates an embodiment of assembly of magnets for oil filter.

DESCRIPTION OF EMBODIMENTS

(4) Oil filter case [20] takes the shape of a cylinder. Referring to FIG. 1, there is illustrated a magnet [22] on the side of the oil filter case [20]. The case is usually made of steel. Hence, magnet [22] is secured on the case [20] using magnetic force.

(5) Magnet [22] has two poles. One pole faces the oil filer case [20] while the other pole faces outward. Magnetic field is created around both poles and magnetizes the oil filter case [20].

(6) The outward facing pole can be tapped to direct magnetic field towards the oil filter case [20]. A steel member [24] is used to direct magnetic field towards the oil filter case [20]. The steel member [24] has to be in contact only with the outward facing pole of the magnet and oil filter case [20].

(7) Oil filter is made in various radius sizes. In order to maintain contact between the magnet pole and oil filter wall, the steel member [24] is adapted to maintain constant contact between these surfaces.

(8) The steel member [24] has three parts: a pivot unit [26], a pivot extender [28] and a bridge unit [30]. The pivot unit [26] is placed near the outward facing pole and it allows the steel member [24] to be pivoted. The pivot extender [28] couples the pivot unit and provides a magnetic field path from the pole of the magnet. A bridge unit [30] connects the pivot extender with oil filter wall to provide a magnetic field path back to the oil filter case. Note that the steel member touches one part of the magnet only and divert that magnetic field to one part of the oil filter case.

(9) The pivot unit [26] is important in this assembly so that the steel member [24] can be adapted to fit onto oil filter magnet of various sizes. The magnet sticks on a radius line while the bridge unit sits on a different radius line. The magnetic coupling of outward facing pole with the oil filter wall can increase magnetic attraction of ferrous material. This arrangement creates a pseudo horseshoe magnet effect. Horseshoe magnet brings two magnetic poles close to each other to create a stronger magnetic field.

(10) A plurality of magnets can be arranged along the circumference of the cylinder case [20], as shown in FIG. 2. Each magnet [22] is paired with steel members [24] to tap outward facing pole back to oil filter case. A band case 32 comprises a plurality of body members 34. Each of the plurality of body members 34 is used to hold a corresponding magnet 22 and a corresponding steel member 24.

(11) In one embodiment of assembly having two to eight magnets [22] and two to eight steel members [24], the magnets are arranged so that the same pole will face the oil filter case. Hence, the opposite pole of the magnets will be tapped by steel member [24] to provide a magnetic field path back to the oil filter case.

(12) The magnets and steel member are provided with adjustable band case and the radius of the band can be adjusted to fit many sizes of oil filter. One embodiment of the band case is provided in Malaysia patent MY 131,072.

(13) Accordingly, a magnet assembly for oil filter is described. The magnet assembly directs the magnetic field from outward pole towards the oil filter wall to create a pseudo horse shoe magnet effect.
