A cleanroom or clean room is a facility ordinarily utilized as a part of specialized industrial production or scientific research, including the manufacture of pharmaceutical items and microprocessors. Cleanrooms are designed to maintain extremely low levels of particulates, such as dust, airborne organisms, or vaporized particles. Cleanrooms typically have a cleanliness level quantified by the number of particles per cubic meter at a predetermined molecule measure. The ambient outdoor air in a typical urban area contains 35,000,000 particles for each cubic meter in the size range 0.5 μm and bigger in measurement, equivalent to an ISO 9 cleanroom, while by comparison an ISO 1 cleanroom permits no particles in that size range and just 12 particles for each cubic meter of 0.3 μm and smaller.

This utility model relates to the field of steel door technology and discloses a safety protection structure for preventing hand pinching in steel cleanroom doors. The structure includes a door frame, a support frame fixedly connected to the top of the door frame, a motor fixedly connected inside the support frame, an elliptical wheel fixedly connected to the drive end of the motor, a sliding shaft fixedly connected to the top of the elliptical wheel, a connecting rod slidably connected to the outer wall of the sliding shaft, a fixed shaft rotatably connected to the inner wall of the connecting rod, a rotating block fixedly connected to the outer wall of the fixed shaft, and a rotating shaft rotatably connected to the top of the rotating block. In this utility model, an infrared sensor controls the motor to drive the elliptical wheel to rotate, stopping the cleanroom door from rotating and causing it to rotate outwards. When an object moves away from the vicinity of the cleanroom door, the motor reverses, the sliding shaft slides to the end of the groove, and the connecting rod drives the rotating block to reset, achieving the anti-pinch function. This structure also provides safety protection; even when the door is stopped, it can still rotate in the opposite direction to prevent objects from getting stuck, thus improving the protection level.

A modular air purification panel
This utility model relates to the field of cleanroom panel technology and discloses a splicable cleanroom panel. It achieves elastic self-locking during splicing by setting up slots, side grooves, locking slots, elastic locking tongues, and spring pieces. When the convex and concave grooves are molded together, the convex head first inserts into the concave shell, and the elastic locking tongue forms a reaction mold-closing with the convex head, causing the elastic locking tongue to also insert into the slot. The elastic locking tongue moves linearly laterally when entering the slot. When the elastic locking tongue touches the wedge-shaped inner wall formed between the side grooves, it is separated by the wedge-shaped inner wall and deforms, sliding into the side groove. As the elastic locking tongue moves into the side groove, the spring piece is pressed and squeezed by the inner wall of the side groove. When the elastic locking tongue continues to penetrate deeper into the side groove, causing the spring piece to reach the locking slot position, the spring piece is released from the squeezing restriction of the side groove and releases its elastic force, causing the spring piece to lock into the locking slot, thus achieving the effect of elastic self-locking.
