[0002] A clean room refers to a well-enclosed space in which parameters such as air cleanliness, temperature, humidity, pressure, and noise are controlled as required. Existing exhaust hoods are used to collect exhaust gas from exhaust gas generating areas, which can improve the efficiency of exhaust gas extraction. Therefore, clean rooms currently also usually use exhaust hoods to extract and collect air.

[0003] According to the search, the Chinese patent with patent number CN217964008U discloses a lifting type exhaust gas suction hood, including a suction hood, an external bracket and a group of traction mechanisms, front and rear lifting ears are fixed on both sides of the top of the suction hood, the external bracket includes a group of gantry frames, the traction mechanism is arranged inside the gantry frame, the traction mechanism includes a rope puller, a group of traction ropes, a double-wheel traction wheel and two single-wheel traction wheels, the rope puller is fixed on the inside of a column of the gantry frame, one end of the two traction ropes is connected to the rope puller, and the double-wheel traction wheel and the two single-wheel traction wheels are fixed side by side on the bottom surface of the top beam of the gantry frame. The utility model can drive the suction hood to perform lifting and lowering operations through two traction mechanisms, and at the same time, the rope pullers of the two traction mechanisms are synchronously linked through a linkage rod, which can stably and accurately lift and lower the suction hood, increase the size of the space around the exhaust gas area, and facilitate the staff to maintain the area where the exhaust gas is generated.
