Novel efficient air supply opening diffuser plate

The invention relates to a novel efficient air supply opening diffuser plate. The novel efficient air supply opening diffuser plate has the following structural form: the diffuser plate (1) is of a square structure, a round air outlet plate is arranged in the middle of the diffuser plate (1), an upper plate extending out upwards from the diffuser plate (1) is arranged on the periphery of the diffuser plate (1), and multiple side air outlet areas (2) are arranged on the upper plate; according to the round air outlet plate, a round perpendicular air outlet area (4) is arranged in the middle, andmultiple annular rotary flow slope air outlet areas (3) are arranged on the side face of the round perpendicular air outlet area (4). The novel efficient air supply opening diffuser plate is providedwith the multiple air outlet areas, and has the beneficial effects that the better the dilution effect is good, the rapier and more uniform the airflow diffusion effect is, the airflow type of the diffusion plate is most clos
