Description:
FIELD OF THE INVENTION  
       [0001]     The present invention generally relates to a magnetic device for fuel, and more specifically to a magnetic device for easier attachment to fuel pipes and improving fuel combustion.  
       BACKGROUND OF THE INVENTION  
       [0002]     Cars are one of the most popular means for transportation. The power source of a car comes from the combustion of fuel. If the fuel is completely combusted, the energy provided by the combustion is greater. On the other hand, if the fuel is not completely combusted, the fuel consumption increases as the efficiency decreases and a larger amount of CO will be released to pollute the air. It is therefore important for car manufacturer to research for improvement in fuel combustion.  
         [0003]     Conventional techniques for improving the fuel combustion efficiency can be divided into two major categories. The first category is to use ultra infrared mineral in the fuel to refine the fuel molecules so that the reaction with oxygen molecules during the combustion will be more complete The disadvantage of this approach is that the mineral must be directly placed inside the fuel tank or the fuel must be sure to pass the mineral for a long period of time to improve the reaction. The second category is to use the magnetization. By placing a magnetic material along the path of the fuel flow, the fuel molecules will be magnetized so that the oil-gas mixture has a more uniform structure for better combustion. The second category is in the mainstream of the application. However, as the technique requires a more complicated structure, it is imperative to develop a magnetic device with a simple structure and easy to use.  
       SUMMARY OF THE INVENTION  
       [0004]     The present invention has been made to overcome the above-mentioned drawback of conventional magnetic devices. The primary object of the present invention is to provide a magnetic device with a simple structure and easy to use. By using two magnets having their opposite poles facing each other, the magnets of the magnetic device can fit on the opposite sides of a fuel pipe. The magnetic field magnetizes the fuel flowing through the pipe so that the combustion will be more complete to save the fuel and increase the power.  
         [0005]     Another object of the present invention is to provide an inexpensive magnetic device. Although the primary element, the magnets, of the present invention requires special manufacturing. The other elements, including the screw and the screw cap, are both inter-exchangeable off-the-shelf parts. Therefore, the manufacturing cost of the magnetic device of the present invention is competitive in the market.  
         [0006]     Yet another object of the present invention is to provide a magnetic device that is easier and safer to install. By using an adjusting structure between the two magnets, the installation of the magnetic device is easier and safer. In addition, the adjusting structure can effectively control the distance between the two magnets so that the magnetic device can be applied to different types of pipes, such as soft hose for gas or water. The adjusting structure also prevents the fuel pipe from long term jamming or crashing forces caused by a tightly clamping magnetic device.  
         [0007]     Another object of the present invention is to provide a magnetic device applicable to a wide range of situations. With the adjusting structure, the magnetic device can be used with fuel pipe/hose, gas pipe/hose, water pipe/hose, and so on. In the meantime, the fluid inside the pipe or the hose can be magnetized for better efficiency.  
         [0008]     To achieve the objects, the present invention provides a magnetic device, including two magnets and an adjusting structure between the two magnets. The two magnets are placed to face each other with their opposite poles so that the magnets are attracted to each other. The adjusting structure is placed between the two magnets to provide the control over the distance between the two magnets.  
         [0009]     The foregoing and other objects, features, aspects and advantages of the present invention will become better understood from a careful reading of a detailed description provided herein below with appropriate reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0021]      FIG. 1  and  FIG. 2  show different view of a magnetic device of the present invention. The magnetic device includes two magnets  1 ,  2  and an adjusting structure  3  placed between magnets  1 ,  2 .  
         [0022]     Magnets  1 , 2  are made of magnetic materials, and can be of any shape, such as a cube, a rectangular block of this embodiment shown in  FIG. 1  and  FIG. 2 , or a round shape or oval shape of the embodiment shown in  FIG. 3 . The material can be permanent magnet or other magnetic material with strong magnetic characteristics. The embodiments of the present invention use the powder metallurgy to manufacture the magnets. The magnets have strong magnetic forces, with one side as N pole, and the other side S pole. The two magnets can be of the same shape so that the manufacture costs can be reduced.  
         [0023]     Adjusting structure  3  is placed between magnets  1 ,  2  for controlling the distance between magnets  1 ,  2  and preventing magnets  1 ,  2  from moving. Adjusting structure  3  is not limited to any specific structure as long as the structure provides control over the distance. The following shows various embodiments of the adjusting structure of the present invention.  
         [0024]      FIG. 2  shows adjusting structure  3 , including two screws  31 ,  32  and a plurality of screw caps  33 ,  34 . Magnets  1 ,  2  include holes  11 ,  21 , and screws  31 ,  32  penetrate magnets  1 ,  2  through holes  11 ,  12 . Screw caps  33 ,  34  are placed on screws  31 ,  32  at the location between magnets  1 ,  2 . By adjusting the location of screw caps  33 ,  34  on screws  31 ,  32 , the distance between magnets  1 ,  2  can be controlled. Because magnets  1 ,  2  are attracted to each other on the opposite sides the pipe, the aforementioned structure is able to stay fixed at the outer rim of the pipe. However, to prevent separation of the magnets  1 ,  2  caused by the vibration of the car during traveling, additional screw caps  35 ,  36  can be added to screws  31 ,  32  at the parts that extend beyond magnets  1 ,  2 , as shown in  FIG. 4 . The advantage of this adjusting structure is that it includes only a few elements, and the elements are off-the-shelf inter-exchangeable parts. This further reduces the manufacture cost.  
         [0025]      FIG. 5  shows a cross-sectional view of another embodiment of an adjusting structure  4 , including twp screws  41 ,  42 , and a plurality of screw caps  43 . The difference of this embodiment is that screws  41 ,  42  have different size of diameter at one end, which penetrates holes  11 ,  21  of different sizes. Because the diameters are different, screw caps  43  are only placed between magnets  1 ,  2  for controlling the distance. Additional screw caps  45 ,  46  can be placed on the extending parts of screws  41 ,  42  for preventing magnets from falling off.  
         [0026]      FIG. 6  and  FIG. 7  show another embodiment of an adjusting structure  5 , including two fixed elements  51 ,  52 , and two fixed screws  53 ,  54  and a plurality of screws  55 . The outer surfaces of fixed elements  51 ,  52  form a sealed container. The center of the formed container includes receiving spaces  511 ,  521 , in which magnets  1 ,  2  situate and stay fixed. Extruding planes  512 ,  522  are on both sides of the container, with penetrated holes for screws  53 ,  54 . The distance between fixed elements  51 ,  52  is controlled by two screw caps on each screw  53 ,  54 . Additional screw caps  56  can be added to the end of screws  53 ,  54  to prevent from falling off caused by vibration. The inside of fixed elements  51 ,  52  further includes a plurality of separators  514 ,  524 , made of magnetic conductive material, such as iron sheet, to reduce the magnetic field outside of fixed elements  51 ,  52  in order to avoid effecting the electronic products surrounding the pipes. In summary, as the embodiments shown in  FIGS. 2, 4 ,  5 , and  6 , the adjusting structure is not limited to any specific type or shape. Any structure that can be used to control the distance between the two magnets can be used as the adjusting structure of the present invention.  
         [0027]      FIG. 8  shows an application of the present invention. When installing the present invention on a fuel hose  6  of a car, it is suggested to start with a large distance between screw caps  33 ,  34  on screws  31 ,  32  because magnets  1 ,  2  exert strong magnetic force. Then, screws  31 ,  32  penetrate magnet  2  (or magnet  1 ), and screw cap  35  (not shown) is used to fix at the end of the screws. The entire magnetic device is moved towards fuel hose  6  so that fuel hose  6  is placed between screws  31 ,  32 . The remaining ends of screws  31 ,  32  then penetrate magnet  1  (or magnet  2 ). Be sure to make the two magnets having their opposite poles facing each other. Adjusting screw caps  33 ,  34  so that magnets  1 ,  2  will slowly move towards fuel pipe  6 , and finally the magnets snuggly hugs the fuel hose.  
         [0028]     In the above embodiment, the fuel hose is used for explanation. However, the present invention can be used in other applications, such as gas hose or water hose so that the gas or liquid flowing through the hose will be magnetized to improve the combustion efficiency or better absorption in the case of water.  
         [0029]      FIG. 9  and  FIG. 10  show another adjusting structure  7  of the present invention, including two fixed elements  71 ,  72 , two fixed screws  73 ,  74 , and a plurality of screw caps  75 . The outer surfaces of fixed elements  71 ,  72  form a sealed container. The center of the formed container includes receiving spaces, in which magnets  1 ,  2  situate and stay fixed. The inside of fixed elements  51 ,  52  further includes a plurality of separating sheets  711 ,  721  and a plurality of separating blocks  712 ,  722 . Separating sheets  711 ,  712  are made of magnetic conductive material, such as iron sheet. Separating blocks  712 ,  722 , and fixed elements  71 ,  72  are made of non-conductive material. Therefore, the space between two magnets  1 ,  2  shows a strong magnetic field, while the surrounding area shows a weak magnetic field to avoid effecting the electronic products surrounding the pipes. Holes  713 ,  723  on fixed elements  71 ,  72  are for the penetration of screws  73 ,  74 . The distance between fixed elements  71 ,  72  is controlled by two screw caps  75  on each screw  73 ,  74 . The surfaces of fixed elements  71 ,  72  facing each other further include extrude blocks  714 ,  724  for placing the fuel hose.  
         [0030]     In the embodiment shown in  FIG. 9  and  FIG. 10 , screws  73 ,  74  can also be a screw with a larger head on one end so that the number of screw caps used in the structure can be further reduced, as well as simplifying the assembly of the magnetic device.  
         [0031]     Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
