Title: Drainline Cannon

Description:
FIELD OF THE INVENTION 
     The present invention relates generally to HVAC and plumbing system maintenance. More specifically, an apparatus used to clean HVAC equipment and plumbing systems. 
     BACKGROUND OF THE INVENTION 
     HVAC refers to Heating, Ventilation and Air Conditioning equipment, which incorporates a control system to regulate the operation of a heating and/or air conditioning system. An integral part of this system are the ducts, which are passages used to deliver or remove air throughout the system. These ducts commonly attract a buildup of sentiments such as dust, cobwebs, hair, debris, etc., which can clog the ducts or circulate harmful containments throughout the building over time. 
     The present invention is an apparatus which can be used to clean HVAC or other related equipment. 
     SUMMARY 
     In accordance with the present invention, a novel apparatus is provided. The present invention comprises a main round cylinder, a round plate, a piston rod inserted into the main round cylinder, a handle mounted to one end of the piston rod, a nipple tube attached to the round plate, and an insert mounted to one end of the piston rod. 
     In one embodiment, the present invention includes a main round cylinder with a first open end and a second open end, the second open end attached to a round plate with a hole defined axially and centrally through the round plate; a piston rod inserted into the main round cylinder; a handle mounted to one end of the piston rod; a nipple tube attached to the round plate; and an insert mounted to one end of the piston rod. 
     In some embodiments, the main round cylinder includes a clear transparent tube design to makes it especially easy for the user to see the results.

     DETAIL DESCRIPTIONS OF THE INVENTION 
     All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention. 
     The present invention, herein referred to as “Drainline Cannon”, is an apparatus intended to be used as an efficient device to clean clogged, common HVAC and household drain lines including but not limited to AC drain lines, Heat Pump drain lines, sink drains, shower drains, toilet drains etc. 
     Drainline Cannon utilizes air and water pressure to remove clogs, clean and maintain drain lines effectively and efficiently. 
     As shown in  FIGS.  1 - 7   , the present invention provides an apparatus  100  comprising: a main round cylinder  10 , a round plate  15 , a piston rod  20 , a handle  25 , a nipple tube  30 , and an insert  27 . 
     As shown in  FIG.  4   , in some embodiments, the main round cylinder  10  may include a first open end  11  and a second open end  12 , the second open end  12  can be attached to the round plate  15  having a hole defined axially and centrally through the round plate  15 . 
     The piston rod  20  may be configured to be inserted into the main round cylinder  10 . The handle  25  can be connected to one end of the piston rod  20 . 
     The nipple tube  30  can be attached to the round plate  15 . In some embodiments, the nipple tube  30  may include a passage extending along a length of the nipple tube  30 , wherein the passage is connected to the hole of the round plate  30 . 
     The insert  27  can be mounted to one end of the piston rod  20 . In some embodiments, the insert  27  can be an optional component and the apparatus  100  may not include the insert  27 . The main round cylinder  10  is a circular and cylindrical tube. 
     As shown in  FIG.  3   , the piston rod  20  may include a distal end  28  and a proximal end  29 . The piston rod  20  can be inserted into the main round cylinder  10  through the first open end  11  of the main round cylinder  10 . The insert  27  may be mounted in the area near the the distal end  28  of the piston rod  20 . 
     The insert  27  can be configured to be moved reciprocally in the main round cylinder  10 . When the piston rod  20  is fully inserted in the main round cylinder  10 , the proximal end  29  of the piston rod  20  may extend through the first open end  11 . The handle  25  can be mounted to the proximal end  29 . 
     In one embodiment, as shown in  FIG.  5   , a piston space  18  can be arranged in the interior of the main round cylinder  10  and the insert  27  can be slidably connected in the piston space  18 . 
     In some embodiments, when the piston rod  20  is fully inserted in the main round cylinder  10 , the present invention may include a gap  35  between the main round cylinder  10  and the handle  25 , as shown in  FIG.  1    and  FIG.  2   . 
     The present invention may be made from any suitable material, including plastic, elastomer, or metal. In some embodiments, the main round cylinder  10  can be made from transparent plastic. 
     In use a user of the present invention (Drainline Cannon) moves the piston rod  20  inward, creating air or water pressure. The direction of the piston rod  20  can be reversed, creating negative pressure. 
     In some embodiments, the main round cylinder  10 , may include a clear transparent tube to makes it especially easy for the user to see the results. 
     Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention.
