AI Technical Summary
When existing cleanroom doors are opened or closed, the sweeping strips come into contact with the floor, easily bringing in dust and impurities and contaminating the cleanroom.
A cleanroom steel door was designed, comprising a metal door frame, a cleanroom door, rubber strips, and a blocking mechanism. The blocking mechanism consists of a U-shaped baffle, a collection box, and a triangular block. The inclined side of the triangular block automatically collects dust, which is swept into the collection box by the rubber strip and then pulled out of the collection box by a pull plate for cleaning.
It effectively prevents dust and impurities from entering the cleanroom, while increasing the sealing of the door and door frame to prevent outside air from entering and facilitate the cleaning of dust and impurities.
