   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims. 
   Referring to  FIGS. 2 to 4 , there is shown an oil mist filtering blower  30  having a tube fitting  31  with air suction port  311  and is connected in series to an oil collection box module  40 . The position of an air discharging tube  32  is mounted with a cyclone separator  50 . When the blower  30  is in operation, oil mist residue is sucked from the oil collection box module  40  for a preliminary filtering, and after the filtering, the oil mist residue enters the blower  30  and passes through the air discharging tube  32  into the cyclone separator  50  for another filtering of oil residue. 
   As shown in  FIGS. 5 and 2 , the oil collection box module  40  comprises a box body  41 , oil collection seat body  42 , a filter  43  and a covering plate  44 . 
   The box body  41  is a hollow shell body having an opening facing the top and the bottom face of the box body is protruded out with a plurality of vertical pillars  411  for locking the oil collection seat body  42  using screw  412 , and a lateral side of the box body  41  is provided with a large connection tube  413  with an air suction port  4131 . A small connector  414  having a streaming hole  4141  is locked at a proximal position to the bottom section of the box body  41 . On the other lateral side of the box body  41 , a notch  415  is provided which is used for placing or retrieving the filter  43 , a hinge  416  and a hook pivot  417  are used for mounting an actuating door  418  such that the closing of the actuating door  418  seals the notch  415  and the inner lateral face of the actuating door  418  is provided with a sealing ring  419 . 
   In the present invention, the downward face of the oil collection seat body  42  is depressed with a conic section  422  having a streaming hole  421 , and the top face of the oil collection seat body  42  is used to hold the filter  43  such that the filter  43  is exactly positioned at the abdomen region of the box body  41 . 
   The cover plate  44  is mounted to the top section of the box body  41  using screws  441 , and the top section is protruded to form a connection tube  422  having mounted with sealing ring  443 . 
   The oil collection box module  40  is connected to the tube fitting  31  of the blower  30  by the connection tube  442 , and screw  444  is used to lock the oil collection box module  40 . 
   As shown in  FIGS. 6 and 2 , the cyclone separator  50  comprises a manifold tube  51 , filtering material  52  and a top cover  53 , and the manifold tube  51  is integrally formed as one unit comprising a bottom tube  511 , a top tube  512 , and a side tube  513 ; and the lower section of the bottom tube  511  is provided with a conic section  514  for fastening a streaming connector  515 . The wall of the top tube  512  is provided with a lateral opening  516  and a hinge and a hook  517  are used to pivotally mount an arch shape actuating door  518 . When the door  518  is closed, the side opening  516  is exactly sealed, and the top tube  512  is for holding the filtering material  52  and the lateral opening  516  is used for placing or withdrawing the filtering material  52 . 
   The top cover  53  is locked at the top section of the manifold tube  51  using screw  531 , and the top face of the top cover  53  is protruded out with a connection tube  533  having an air discharging port  532  and the bottom face thereof is mounted with a protection net  535  locked with screw  534 . The side tube  513  is used to connect the separator  50  to the air discharging tube  32  and is then locked with screw  54 . 
   Referring to  FIG. 7 , in operation, oil-mist is rapidly sucked from the air suction port  4131  of the connection tube  413 , and then via the wall of the filter  43  to proceed with first time filtering of oil residue and then through the air discharging tube  32 . After that, the oil mist passes from the lateral tube  513  into the manifold tube  51 , and through the filtering material  52  for a second oil residue filtering such that clean air is discharged via the air discharging port  532  at the top cover  53 . The oil mist as a result of the atmospheric turbulence is condensed at the internal wall of the manifold tube  51 , forming into oil residue and flowing downward to the streaming connector  515  for recycling. The collected oil residue at the box body  41  of the oil collection box module  40  is directed from the connector  414  for recycling. Accordingly, a secondary filtering is effected. 
     FIGS. 8 and 9  are another preferred embodiments in accordance with the present invention. The bottom face of the box body  61  is provided with a large air suction port  611  and the bottom face is positioned with a shock reducing pad  62  with porous pores  621  and a connection tube  63 , and the connection tube  63  is connected in series to the bottom section of the air suction port  611  of the box body  61  by screws  612 , and the tube end of the bottom section of the connection tube  63  is mounted with a protection net  631 . Thus a vertical type suctioning of oil mist residue is obtained. 
   In operation, when the blower  30  is switched on, oil mist residue is sucked via the protection net  631  of the connection tube  63 . The oil mist residue passes through the porous pores  621  and the suction port  611 , and then to the wall of the filter  43  for filtering of oil residue. After, the oil mist residue passes through the suction port  611  via the air discharging tube  32  of the blower  30  and then via the side tube  513  into the manifold tube  51 . A second filtering is occurred at the filtering material  52  and the clean air is passing through the air discharging port  532  of the top cover  53  for discharging. The oil mist as a result of the atmospheric turbulence is condensed at the internal wall of the manifold tube  51 , forming into oil residue and flowing downward to the streaming connector  515  for recycling. The collected oil residue at the box body  61  of the oil collection box module  40  is directed from the connector  414  for recycling. When the blower  30  is switched off the collected oil residue flows from the suction port  611 , the protection net  631  of the connection tube  63  to the machine. Accordingly, a secondary filtering is effected. 
   Referring to  FIG. 10 , there is shown another preferred embodiment, the bottom section of the connection tube  63  employs an extension connection  64  to connect to a bending tube  641  and the end of the bending tube  641  is mounted with another protection net  642 . Thus, the extension tube  64  and the bending tube  641  are extended into the interior of a fabrication machine to suck oil mist residue.
