[0035] It should be noted that since the operating space 110 is equipped with a screen frame for placing the screen, the screen can also be placed in the operating space 110 and operations can be performed on the screen.
[0036] Understandably, some processes that easily generate volatile organic gases can be carried out inside the operating space 110. For example, the storage and addition of diluents or the filtration of slurry in the screen printing process can be carried out inside the operating space 110. Understandably, the materials or tools to be used can be placed inside the operating space 110 in advance, thereby lowering the opening and closing door 170 by a preset height, reducing the size of the opening between the operating space 110 and the external space where the workers are located, reducing the spread of volatile gases into the working environment, and improving the air environment inside the workshop. At this time, the workers can put their hands into the operating space 110 to work on the tools or materials, which can prevent the gases in the operating space 110 from spreading to the workers on a large scale. Turning on the exhaust fan 160 can further prevent the workers from inhaling the volatile gases in the operating space 110, reducing the harm of volatile organic gases to the workers' bodies.
[0037] It should be noted that, to facilitate observation of the interior of the operating space 110 by operators, the opening and closing door 170 in this embodiment may optionally be made of transparent material. It should also be noted that the opening and closing door 170 is a standard feature in the field of fume hood technology, and its specific structure and movement mechanism will not be described in detail here.
