The air member 93 detects the air flow velocity (ie, the wind speed) to ensure the stability of the circulating airflow, and surely blocks the harmful substances in the operating space 912 from dissipating outside the cabinet 91 through the operation window 913; thus, floating in the The hazardous substances in the operating space 912 can be completely extracted.

However, in the case where the amount of exhaust air does not change, when the operation window 912 follows the door panel 92, when the opening area is increased, it is easy to cause the wind speed in the operating space 912 to drop, and the conventional exhaust cabinet 9 has a harmful gas leakage; based on this, the conventional exhaust cabinet 9 relies more on the wind measurement. The air flow rate is monitored to ensure that the air flow is stable, but the air measuring member 93 is disposed on one of the inner walls of the cabinet 91 and adjacent to the operation window 913, so that it is easily subject to the door panel 92. The degree of movement is different, so that the wind measuring member 93 may block the wind measuring member 93 due to the partial door panel 92, and is disturbed when detecting the wind speed of the air inlet, so that the wind speed measured by the wind measuring member 93 is somewhat There is a drop in the actual wind speed, which affects the stability of the circulating airflow.

In view of this, the conventional exhaust cabinet 9 does have a need for further improvement to further solve the problems as described above.
