A patent application (Publication Number: US20230417791A1) describes a device designed to measure air speed near an air outlet of an air curtain mounted close to the opening of a wafer box. The device includes fixing members and air speed measuring members, with sensors positioned below the air curtain to measure the air speed accurately. The air speed measuring members consist of a main body and probing rods, with the sensors arranged at preset intervals on a horizontal plane below the air curtain. Additionally, sliding members are included to facilitate movement of the sensors towards or away from the wafer box for efficient measurement.

Furthermore, the device incorporates control units, switching units, storage units, and wireless transmission units to enhance functionality. The control units transmit signals to the sensors for air speed detection, while the switching units enable sensor activation. Data detected by the sensors is stored in the storage units and transmitted wirelessly to external electronic devices. Notably, all these components are housed within the air speed measuring members, ensuring a compact and integrated design for effective air speed measurement in the wafer box setup.
