Vent flapper with intake/exhaust holes

Abstract

A vent assembly, including a vent flapper and one or more air intake openings formed within the vent flapper, wherein the air intake openings allow air to flow both in and out. The assembly may include a removable cover attachable to the vent flapper, or a tube opening and a vent flapper area, wherein the vent flapper area is at least 65 percent larger than the tube opening. The assembly may have air intake openings hexagonal. The assembly may include a tube configured to attach to one of the concentric cylinders, and the backplate may have a plurality of concentric cylinders arranged in decreasing diameter. The cylinders may be separated by dual-sided score lines and at least one of the cylinders is recessed from the backplate. The assembly may have a removable cover configured to block the openings for air intake formed within the vent flapper.

1 . A vent assembly, comprising:
 a vent flapper; and   one or more air intake openings formed within the vent flapper, wherein the air intake openings allow air to flow both in and out.   
     
     
         2 . The vent assembly of  claim 1 , further comprising:
 a removable cover attachable to the vent flapper.   
     
     
         3 . The vent assembly of  claim 2 , further comprising:
 a tube opening; and   a vent flapper area, wherein the vent flapper area is at least 65 percent larger than the tube opening.   
     
     
         4 . The vent assembly of  claim 3 , wherein the air intake openings are hexagonal. 
     
     
         5 . The vent assembly of  claim 4 , wherein the vent flapper area is non-circular. 
     
     
         6 . The vent assembly of  claim 5 , wherein the vent flapper area is substantially square. 
     
     
         7 . The vent assembly of  claim 6 , further comprising:
 a flapper recess, formed on the vent flapper; and   a flapper hinge, wherein the flapper recess substantially ensures the vent flapper rotates around the flapper hinge.   
     
     
         8 . The vent assembly of  claim 7 , further comprising:
 a cover configured to block the air intake openings formed within the vent flapper.   
     
     
         9 . The vent assembly of  claim 3 , wherein the vent flapper area is at least 80 percent larger than the tube opening. 
     
     
         10 . The vent assembly of  claim 9 , further comprising:
 a removable cover configured to block the air intake openings formed within the vent flapper.   
     
     
         11 . A vent assembly, comprising:
 a vent flapper;   one or more air intake openings formed within the vent flapper, wherein the air intake openings allow air to flow both in and out; and   a removable cover configured to block the air intake openings formed within the vent flapper.   
     
     
         12 . The vent assembly of  claim 11 , further comprising:
 a backplate having plurality of concentric cylinders arranged in decreasing diameter, wherein the concentric cylinders are separated by score lines and at least one of the concentric cylinders is recessed from the backplate;   a ventilation tube configured to attach to one of the concentric cylinders; and   one or more tube stoppers to prevent the ventilation tube from being over inserted.   
     
     
         13 . The vent assembly of  claim 12 , further comprising:
 a face plate;   a tooth formed on one of the backplate and the face plate; and   a tooth receiver formed on the other of the backplate and the face plate.   
     
     
         14 . The vent assembly of  claim 13 , wherein:
 the tooth is formed on the backplate, and   the tooth receiver is formed on the face plate.   
     
     
         15 . The vent assembly of  claim 14 , wherein the score lines are dual-sided score lines. 
     
     
         16 . A vent assembly, comprising:
 a vent flapper;   one or more air intake openings formed within the vent flapper, wherein the air intake openings allow air to flow both in and out;   a backplate having a plurality of concentric cylinders arranged in an order of decreasing diameter; and   a tube configured to attach to one of the concentric cylinders, the concentric cylinders are separated by dual-sided score lines and at least one of the concentric cylinders is recessed from the backplate;   a face plate;   a tooth formed on the backplate; and   a tooth receiver formed on the face plate.   
     
     
         17 . The vent assembly of  claim 16 , further comprising:
 a removable cover configured to block the air intake openings formed within the vent flapper.
