Air vent with louvers

Abstract

An air vent includes a chassis and a plurality of louvers. The chassis includes a bottom plate and a side plate located on the bottom plate. The plurality of louvers is located on the side plate. Each of the plurality of louvers includes a body and a shaft located on the body. The body of each of the plurality of louvers is rotatable about the shaft of each of the plurality of louvers relative to the side plate. An angle defined between the bottom plate and the shaft of each of the plurality of louvers is substantially 45 degrees.

         2 . The air vent of  claim 1 , wherein the side plate is substantially perpendicular to the bottom plate. 
     
     
         3 . The air vent of  claim 1 , further comprising a mounting member and a locking member, wherein the mounting member is secured to the side plate, and the locking member secures the plurality of louvers to the mounting member. 
     
     
         4 . The air vent of  claim 3 , wherein the mounting member defines a plurality of first cutouts, the locking member defines a plurality of second cutouts, and the shaft of each of the plurality of louvers is received in each of the plurality of first cutouts and each of the plurality of second cutouts. 
     
     
         5 . The air vent of  claim 4 , wherein the plurality of first cutouts and the plurality of second cutouts are substantially semicircular. 
     
     
         6 . The air vent of  claim 3 , wherein the mounting member defines a plurality of mounting slots, the locking member comprises a plurality of locking portions, and the plurality of locking portions are engaged in the plurality of mounting slots to secure the locking member to the mounting member. 
     
     
         7 . The air vent of  claim 6 , wherein each of the plurality of locking portions is resiliently deformable, so as to engage each of the plurality of locking portions in each of the plurality of mounting slots. 
     
     
         8 . The air vent of  claim 3 , wherein the mounting member comprises a plurality of limiting blocks, each of the plurality of limiting blocks restricts a rotation range of the body of each of the plurality of louvers. 
     
     
         9 . An air vent comprising:
 a mounting member, the mounting member comprising two mounting flanges, the two mounting flanges substantially parallel to each other, an angle defined between a horizontal surface and each of the two mounting flanges is substantially 45 degrees; and   a plurality of louvers located on the two mounting flanges, each of the plurality of louvers comprising a body and a shaft located on the body, the body of each of the plurality of louvers is rotatable about the shaft of each of the plurality of louvers relative to the mounting member, the shaft of each of the plurality of louvers being substantially perpendicular to the two mounting flanges.   
     
     
         10 . The air vent of  claim 9 , further comprising a locking member, wherein the locking member secures the plurality of louvers to the two mounting flanges of the mounting member. 
     
     
         11 . The air vent of  claim 10 , wherein the mounting member defines a plurality of first cutouts, the locking member defines a plurality of second cutouts, and the shaft of each of the plurality of louvers is received in each of the plurality of first cutouts and each of the plurality of second cutouts. 
     
     
         12 . The air vent of  claim 11 , wherein the plurality of first cutouts and the plurality of second cutouts are substantially semicircular. 
     
     
         13 . The air vent of  claim 10 , wherein the mounting member defines a plurality of mounting slots, the locking member comprises a plurality of locking portions, and the plurality of locking portions are engaged in the plurality of mounting slots to secure the locking member to the mounting member. 
     
     
         14 . The air vent of  claim 13 , wherein each of the plurality of locking portions is resiliently deformable, so as to engage each of the plurality of locking portions in each of the plurality of mounting slots. 
     
     
         15 . The air vent of  claim 10 , wherein the mounting member comprises a plurality of limiting blocks, each of the plurality of limiting blocks restricts a rotation range of the body of each of the plurality of louvers. 
     
     
         16 . The air vent of  claim 15 , wherein the mounting member defines a plurality of ventilation openings, the body of each of the plurality of louvers is rotatable between a closed position, where the plurality of louvers substantially covers the plurality of ventilation openings, and an open position, where the plurality of louvers is open, and the body of each of the plurality of louvers abuts each of the plurality of limiting blocks. 
     
     
         17 . The air vent of  claim 9 , further comprising a chassis, wherein the chassis comprises a bottom plate and a side plate located on the bottom plate, the mounting member is secured to the side plate, and an angle defined between the bottom plate and the shaft of each of the plurality of louvers is substantially 45 degrees.
