Exhaust device with barrier

This creation relates to a venting device with a baffle, especially one that can effectively prevent the escape of soot or contaminants and improve the exhaust efficiency for use in factories, laboratories and kitchens.

The "traditional exhaust device" is not much different from the top suction suction hood generally used in the workplace. When the exhaust device is inhaled, air and pollutants will enter through the suction port and then through the conduit. To the outside. Among them, the air flow rate near the position of the suction port is large, and the air flow rate away from the position of the suction port will rapidly decrease as the distance from the suction port increases. Therefore, within a short distance below the suction port, the speed of the air upwards has become small, so that the upward suction force is insufficient, and it is highly susceptible to disturbance airflow from the movement of people, fans or air-conditioning operations. Allows soot or contaminants to escape as the flow of disturbed air flows.

In view of the above problems, the current effective improvement method is to add a rectangular blocking plate on the left and right sides of the suction hood of the exhaust device to prevent the soot or pollutant from escaping with the flow of the disturbing airflow, thereby increasing the row.
