OIL TANK CLEANING BALL

Abstract

An oil tank cleaning ball serves for attracting metal impurities within an oil tank, and has a function of checking whether the oil tank is dirty. The oil tank cleaning ball comprises an enclosing body made of non-magnetic material, but the magnetic lines can pass through the enclosing body, an outer surface of the enclosing body being uneven and rough, having sags and crests so as to expand an area of the outer surface for attracting impurities; a magnetic metal sheet enclosed within and fixed by the enclosing body; the magnetic lines emitting from the magnetic metal sheet can pass through the enclosing body so as to attract the impurities within the oil tank. Amount of impurities on the oil tank cleaning ball is used to decide whether an interior of the oil tank is dirty.

DETAILED DESCRIPTION OF THE INVENTION

[0015] In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.

[0016] With reference to FIGS. 1 to 7, the oil tank cleaning ball 1 according to the present invention is illustrated. The present invention includes the following elements.

[0017] An enclosing body 10 is made of non-magnetic material, but magnetic lines can pass through the enclosing body 10, such as rubber, plastics, etc. Referring to FIG. 1, an outer surface 11 of the enclosing body 10 are uneven and rough, has sags and crests so as to expand an area of the outer surface 11 for attracting impurities, such as iron powders, rust powders, or other metal particles or powders.

[0018] A magnetic metal sheet 20 is enclosed within and fixed by the enclosing body 10. Preferably, the magnetic force from the magnetic metal sheet 20 are proper so that it only acts in a near field of the enclosing body 10 so as to attract the impurities nearby, while the enclosing body 10 is not attached to walls of oil tanks.

[0019] A line 30 has one end attached to the enclosing body 10.

[0020] Referring to FIG. 6, in use of the present invention, the oil tank cleaning ball 1 of the present invention is placed into to an oil tank 100, sinks in the gasoline of the oil tank 100 and places to a bottom of the oil tank 100 so that the oil tank cleaning ball 1 can attract the impurities on the bottom of the oil tank 100 to avoid these impurities to move to an oil pump 110 in the bottom of the oil tank 100 so as to seal the oil pump 110 and cause the oil pump 110 cannot act. The line 30 connected to the enclosing body 10 is exposed out of an opening 120 of the oil tank 100 so that the user can pull the oil tank cleaning ball 1 from the line 30 to cause the oil tank cleaning ball 1 moves out from the oil tank 100. Thereby, the use can clean the oil tank cleaning ball 1 and can view the oil tank cleaning ball 1 to decide whether an interior of the oil tank 100 is dirty and to decide whether the oil tank 100 is necessary to be cleaned.

[0021] With reference to FIGS. 2 to 5, in this embodiment, the enclosing body 10 is formed by two sheet bodies 40. An inner side of each sheet body 40 is formed with a recess 41. After combining the two sheet bodies 40, the magnetic metal sheet 20 is enclosed with the two recesses 41 of the two sheet bodies 40. One inner surface of one sheet body 40 is corresponding to that of another sheet body 40 so that after combination, the magnetic metal sheet 20 is tightly sealed within the recesses 41.

[0022] Combination of the sheet bodies 40 is performed by any way which can combining the two sheet bodies 40, such as screwing by screws or studs, sticky, or buckling, etc. Referring to FIGS. 3 and 5, it is illustrated that two screws 50 pass through the two sheet bodies 40 so as to combine the two sheet bodies 40 as one integral body and the magnetic metal sheet 20 are enclosed within the recesses 41.

[0023] After combination, the magnetic metal sheet 20 are enclosed within the recesses 41, the magnetic lines emitting from the magnetic metal sheet 20 can pass through the enclosing body 10 so as to attract the impurities with the lower side of the oil tank 100.

[0024] In the present invention, the outer surface 11 of each sheet body 40 is uneven for providing greater surface area for locating impurities. In the present invention, unevenness of each outer surface 11 of the sheet body 40 is formed by a plurality of round posts 61 (referring to FIGS. 2 and 3), or a plurality of rectangular posts 62 (referring to FIGS. 2 and 5) so as to provide larger combining area.

[0025] FIG. 7 shows another embodiment of the present invention, in this embodiment, a plurality of oil tank cleaning balls 11 are connected so as to form as an oil tank cleaning ball set 5. In use, this oil tank cleaning ball set 5 can provide a larger area for attracting impurities. In FIG. 7, there are four oil tank cleaning balls 1 are connected together.

[0026] In above mentioned applications, the oil tank cleaning balls 1 can be connected by any ways which are all within the scope of the present invention, for example, by using the line 30 to connect the oil tank cleaning balls 1 one by one.

[0027] Advantages of the present invention are that the impurities (for example, iron powders, rust powders, or other impurities such as metal particles or powders) within an oil tank can be cleaned easily and conveniently by the oil tank cleaning ball of the present invention. Another, the oil tank cleaning balls can be used to check whether the interior of the oil tank is sufficient dirty so that it is needed to be cleans. These functions provide sufficient convenience to the drivers. It can be used to prevent that the oil pump does not act abruptly due to the pump is sealed by metal impurities. Therefore, it can avoid many traffic jam accidents due to the destroy of the oil pump.

[0028] The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
