Description

TECHNICAL FIELD

[0001] The application relates to the technical field of workbenches, and discloses a negative pressure workbench for dust-free processing. BACKGROUND

[0002] The negative pressure workbench is a device capable of removing dust and particulate matter in a processing process, so that the overall processing environment is in a dust-free state. The principle is that negative pressure is generated by a built-in fan to form an air flow path from the operation area to the filter. This design allows the air in the work area to be continuously sucked in and passed through the filtration system, thereby keeping the work area clean. When the air passes through the workbench, it is filtered by the filter. These filters can capture and remove dust, bacteria and other particles in the air to ensure that only clean air enters the work area. The filtered clean air is discharged back into the work environment or discharged to the outside through an exhaust system.

[0003] At present, the negative pressure workbench needs to clean the internal filter after a long time of work to maintain the normal filtering performance of the filter. However, the filter needs to be disassembled before it can be cleaned, which is not only cumbersome, but also causes dust to fall around the work area inside the negative pressure workbench during cleaning, thereby polluting the surrounding environment. Therefore, the utility model provides a negative pressure workbench for dust-free processing to solve the above problems. CONTENT OF THE UTILITY MODEL
