Airflow guide cover

Abstract

An airflow guide cover includes a main body, a first ventilation panel, and a second ventilation panel. The main body includes an airflow guiding channel and two opposite sidewalls. The airflow guiding channel includes an air outlet. The first and second ventilation panels are respectively rotatably connected to the sidewalls adjacent to the air outlet. A number of first vents is defined in the first ventilation panel, and a number of second vents is defined in the second ventilation panel. The areas of the first vents and the second vents are different. The first ventilation panel and the second ventilation panel are selectively rotated to cover the air outlet, to adjust airflow exhausting out of the airflow guide cover.

1 . An airflow guide cover, comprising:
 a main body comprising a top wall, two sidewalls extending from opposite sides of the top wall, and an airflow guiding channel bound by the top wall and the sidewalls, the airflow guiding channel comprising an air outlet;   a first ventilation panel rotatably connected to one of the sidewalls adjacent to the air outlet, a plurality of first vents defined in the first ventilation panel; and   a second ventilation panel rotatably connected to the other one of the sidewalls adjacent to the air outlet, a plurality of second vents defined in the second ventilation panel, wherein the areas of the first vents and the second vents are different, the first ventilation panel and the second ventilation panel are operable to be selectively rotated to cover the air outlet.   
     
     
         2 . The airflow guide cover of  claim 1 , wherein each of the first and second ventilation panels comprises a plate and a pivot member, the first and second vents are defined in the corresponding plates of the first and second ventilation panels, first ends of the plates are respectively rotatably connected to the pivot members, and the pivot members are respectively rotatably connected to the sidewalls of the main body. 
     
     
         3 . The airflow guide cover of  claim 2 , wherein two spaced pivot portions protrude outward from an outer surface of each of the sidewalls adjacent to the air outlet, a pivot hole is defined in each of the pivot portions, each pivot member comprises a shaft, opposite ends of the shaft are rotatably engaged in the pivot holes of a corresponding sidewall. 
     
     
         4 . The airflow guide cover of  claim 3 , wherein each pivot member further comprises two pivot portions extending outwards from a lateral side of the corresponding shaft, a pivot hole is defined in each of the pivot portions of the pivot member, two pivot pins respectively extend from top and bottom of the first end of each plate, to engage in the pivot holes of a corresponding pivot member. 
     
     
         5 . The airflow guide cover of  claim 4 , wherein a slot is defined in an end of each sidewall adjoining the air outlet, a latch is formed on a second end of the plate of each of the first and second ventilation panels, when the first ventilation panel covers the air outlet, the latch of the first ventilation panel engages in the slot of the sidewall connected to the second ventilation panel; when the second ventilation panel covers the air outlet, the latch of the second ventilation panel engages in the slot of the sidewall connected to the first ventilation panel. 
     
     
         6 . The airflow guide cover of  claim 5 , wherein the latches are rotatably connected to the second ends of the plates of the first and second ventilation panels, respectively. 
     
     
         7 . The airflow guide cover of  claim 6 , wherein a recess is defined in each plate adjacent to the second end of the plate, to receive the corresponding latch connected to the plate. 
     
     
         8 . The airflow guide cover of  claim 6 , wherein two hooks extending towards each other are formed on the outer surface of each sidewall, when the first and second ventilation panels are respectively rotated towards the sidewalls, the hooks of the sidewalls are capable of engaging with the corresponding first and second ventilation panels.
