[0002] Cabinet exhaust hoods are commonly known as fume hoods. Similar to closed hoods, small parts spray paint cabinets and chemical laboratory fume hoods are typical structures of cabinet exhaust hoods. Large room-type fume hoods have one side completely open, and operators work inside the cabinet. They are mainly used for large-scale painting, powder bagging, etc. When adjusting the air volume of the integrated fume hood, an air volume adjustment mechanism is required.

[0003] The existing Chinese patent CN217616701U disclosed a fume hood air volume adjustment mechanism on October 21, 2022, including a cabinet body, a driving mechanism and a linkage mechanism; the cabinet body: a top cover is provided on its upper surface, and a filter box is provided in the circular hole in the middle of the upper surface of the top cover, and a ventilation pipe is provided in the vent on the upper surface of the filter box, and a horizontal slide rail is symmetrically provided on the lower surface of the top cover, and a slide plate is slidably connected between the two longitudinally distributed horizontal slide rails, and a rack plate is provided at the front end of the slide plate; the driving mechanism: it is arranged on the right side of the front end of the top cover, and the driving mechanism is meshed with the rack plate on the right; the linkage mechanism: its upper end is rotatably connected to the front end of the lower surface of the top cover through a bearing, and the linkage mechanism is meshed with the driving mechanism.

[0004] However, when the above device adjusts the air volume, it adjusts the air volume by means of meshing transmission. Therefore, when adjusting, the air volume is adjusted by changing the air outlets on both sides as a whole, and the air volume on one side cannot be effectively changed for adjustment.
