[0015] This utility model's smoke collection hood features independently distributed suction boxes on its main body. Each suction box is equipped with an opening and closing device for opening and closing the exhaust vent. The opening and closing device includes a motor and a guide plate. The motor drives the guide plate to rotate, thereby opening or closing the exhaust vent. When using a single-sided (left or right) stove, only the exhaust vent of the suction box on that side can be opened, while the exhaust vent on the other side can be closed. This concentrates the airflow in the suction box on that side, improving ventilation efficiency and reducing energy waste. Furthermore, the intelligent control of the exhaust vent through the opening and closing device can reduce the load on the ventilation system. For example, when using a single-sided stove, the load on the ventilation system can be appropriately reduced, extending the equipment's lifespan and lowering energy consumption.
