## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority to U.S. Provisional Application Ser. No. 62/352,457 filed on Jun. 20, 2016, which is hereby incorporated into this specification by reference in its entirety.


BACKGROUND OF THE INVENTION
Air vents are widely used to exhaust air from an interior space of a structure (such as a home) to the ambient environment. FIG. 1 shows a conventional air vent 2 mounted directly to siding 18 (such as wood shingles) of an exterior wall 16 of the structure (not shown) by fastening means such as nails (not shown). Air vent 2 has an opening (not shown) and a rear duct (not shown) that engages with a supply duct (not shown) located in the interior space of the structure. Air vent 2 has a body 4 and damper 6 that may be spring loaded or otherwise configured such that it will open when a high amount of air flow is present and close upon the presence of a low amount of air flow. Air vent 2 also has a cover 108 substantially enclosing damper 6. Air vent 2 has at least one significant drawback. Air vent 2 is mounted directly to the siding of the exterior wall. As such, body 4, damper 6, and cover 108 of air vent 2 protrude outward from siding 18 thereby significantly diminishing the aesthetic appearance of siding 18 and the value of the structure.
SUMMARY OF THE INVENTION
The present invention is an air vent that can be mounted to an exterior wall of a structure such that the air vent blends into the siding thereby making the air vent substantially invisible. The air vent comprises a body comprising an opening and a siding portion disposed below the opening. The air vent further comprises a first siding piece secured to the siding portion that is substantially similar to the siding of the exterior wall. The air vent further comprises a damper moveably engaged with the body between a closed position where the damper prevents air flow thru the opening and an open position where the damper allows air flow thru the opening. The air vent further comprises a second siding piece secured to the damper that is substantially similar to the siding of the exterior wall and overlaps the first siding piece in the closed position. Unlike conventional devices, the air vent of the present invention blends into the siding of the exterior wall making the air vent substantially invisible and increasing the aesthetic appearance of the siding and value of the structure.
