[0002] Marine air distributors are an important component of ventilation systems on ships and offshore platforms, serving as the terminal air outlet devices in air conditioning systems. Marine air distributors are a type of terminal air outlet device in marine air conditioning systems, and can be classified according to their structural shape into trumpet-shaped, grille-shaped, and louvered types, etc., and according to their working nature into direct-distribution air distributors and induced-distribution air distributors.

[0003] Currently, most air distributors on the market typically have a baffle inside the housing.

However, this cannot be adjusted if the motor malfunctions. Furthermore, the baffle has a large area, and when the distance between it and the air inlet decreases, the wind speed increases, which increases the impact on the baffle and the wear caused by vibration. In addition, the outlet air speed is uneven, affecting the comfort of use. Utility Model Content

The air volume can be adjusted under any circumstances, which is more flexible.

[0016] 2. Both the air intake grille and the movable grille are radial grille structures. The ventilation area is changed by altering the mutual shielding area between the air intake grille and the movable grille. The air intake grille is a fixed structure, while the middle and edge positions of the movable grille are connected to the air intake grille, making the movable grille structure stable. The airflow only acts on a part of the movable grille, thereby reducing vibration on the movable grille and reducing wear.

[0017] 3. A buffer is installed at the air outlet. When the push ring is rotated, it can drive the blades to rotate, thereby changing the air direction passing through the air outlet. The airflow acts on the diffuser plate in an inclined direction, avoiding the airflow from going straight out and ensuring the uniformity of the air passing through the diffuser plate, thus improving the user's comfort.
