(1) The cooking fume exhaust fan generates sufficient dynamic pressure and static pressure, forming a sufficiently large effective negative pressure field for cooking fumes suction.

(2) The layout design of the condensing plate forms a complete airflow momentum boundary between the cooking fume suction hood and the AI smoke purifier, which effectively suppresses cooking fumes diffusion and prevents cooking fumes from escaping.

(3) The air volume of the cooking fume exhaust fan is determined according to the amount of cooking fumes generated on the stove, reducing the indoor negative pressure and environmental energy consumption caused by excessive air intake when suctioning cooking fumes.
