Detailed Description

In order to make the technical solution better understood by those skilled in the art, the technical solution in the embodiment of the present application will be clearly and completely described below with reference to fig. 1.

The utility model provides a building ventilation unit, including locating frame 1 of window 13 below, frame 1 inlays in wall body 12, the outdoor one side is equipped with backup pad one 2 above the frame 1, backup pad one 2 is connected with backup pad two 3, backup pad two 3 locate the indoor one side of facing above the frame 1, be equipped with between backup pad two 3 and the backup pad one 2 and strain dirt net 4, impurity such as dust for filtering in the air that passes through, strain dirt net 4, backup pad one 2 and backup pad two 3 enclose into an indoor and outdoor passageway of intercommunication, in order to reach the effect of ventilation.

Be equipped with ventilating board 5 on backup pad 2 to impurity such as dust in the air that gets into outside the filter chamber is equipped with a plurality of ventilation holes 6 on ventilating board 5, in order to ensure the inflow and the outflow of air, ventilating board 5's the lower is higher than the highest point of dirt screen 4, makes ventilating board 5 and dirt screen 4 carry out the dislocation set, in order to weaken the wind-force of the air that gets into.

Be equipped with backup pad three 7 on backup pad two 3, backup pad three 7 passes backup pad two 3 and locates on wall body 12, the one end that window 13 was kept away from to backup pad three 7 is equipped with guide plate 8, so that guide air's flow direction, the top of ventilating board 5 is located to guide plate 8's one end, the handing-over department of backup pad two 3 and dust screen 4 is located to guide plate 8's the other end, in order to avoid the air to flow into guide plate 8, in the airtight space that backup pad one 2 and backup pad two 3 enclose, in order to cause the detention of air and influence the ventilation effect.

The guide plate 8 is arc-shaped, and the convex side on the guide plate 8 is connected with the third support plate 7 so as to guide the flow of the air entering and exhausting.

Be equipped with guide rail 9 on the frame 1, sliding connection has the guard plate 10 that can cover dust screen 4 on the guide rail 9 for open or close ventilation unit, the lower extreme joint of guard plate 10 has and is used for spacing stopper 11, and stopper 11 is located on the frame 1, in order to prevent that guard plate 10 from droing and injuring the pedestrian by a crashing object.

The dust filtering net 4 is of a bending structure, the bending angle is set to be 130 degrees, the dust filtering area is increased, and the ventilation efficiency is improved.
