Description

Technical Field

[0001] This utility model relates to the field of air shower technology, specifically to an air shower for a cleanroom. Background Technology

[0002] An air shower is a versatile local purification device installed between cleanrooms and non-cleanrooms. When people and goods need to enter the clean area, they need to pass through the air shower. The clean air blown out can remove dust carried by people and goods, effectively blocking or reducing dust sources from entering the clean area.

[0003] Application number "CN202421350066.9" describes a cleanroom air shower that addresses the problem that existing cleanroom air shower structures require the air shower's sealed door to be fully opened before entry, allowing outside air to enter the cleanroom and reducing its cleaning effectiveness. However, this design lacks a positioning mechanism for the rotating disc, relying entirely on a motor for control. This results in a potential safety hazard when the disc is stationary, as personnel walking down from it could easily slip and fall. Utility Model Content
