Abstract

A push type exhaust cover, includes: a first cover body, configured with at least one through hole; and a second cover body, one side thereof in combination with one side of the through hole, a curved line configured between the second cover body and the through hole, a periphery of the second cover body in combination with a periphery of the through hole with a dotted broken line, an engagement portion projected from a top surface of the second cover body, pressing the engagement portion down causing the dotted broken line of the second cover body to be broken to fall into the through hole, allowing a top end of the engagement portion to press against another side of the through hole to make the through hole to be in communication with the outside so as to achieve an exhaust effect.

I claim:

         4 . The cover according to  claim 3 , wherein a top portion of a rear end of said engagement portion is configured with an arc section; said arc section in contact with and pressing a periphery of said through hole allows said engagement portion to be passed through said through hole. 
     
     
         5 . The cover according to  claim 1 , wherein a groove is configured on said first cover body, said through hole is configured on said groove, and the width of said second cover body is larger than the one of said engagement portion. 
     
     
         6 . The cover according to  claim 5 , wherein the height of said engagement portion is larger than the width of said through hole. 
     
     
         7 .
