Abstract: The present disclosure provides a control circuit of a blind-mating display having two Type-C interfaces, a control device thereof, and a control method thereof. The control circuit of the blind-mating display having two Type-C interfaces includes a display control module, a first Type-C interface module, a second Type-C interface module, a first switching switch module, a second switching switch module, and a dielectric module. The dielectric module is electrically connected to the first Type-C interface module, the second Type-C interface module, and the display control module. The first switching switch module is electrically connected to the first Type-C interface module, the second Type-C interface module, and the display control module. The second switching switch module is electrically connected to the first Type-C interface module, the second Type-C interface module, and the display control module. The present disclosure is alternately communicated with the source device and the PD device.

Abstract: A device for dust removal through air curtain isolation and self-circulation purification, including a material input transferring cabin, a main isolation cabin, a material output transferring cabin and a control cabinet. By employing three independent interlayer isolation cabins, a self-circulation purification device formed of self-circulation air pipes is disposed in the main isolation cabin, and an airflow cleaning air curtain is respectively disposed between the main isolation cabin and the material input transferring cabin and also between the main isolation cabin and the material output transferring cabin. By means of air curtain isolation and self-circulation purification, the spreading of dust resulting in pollution and interference to the environment of both the processing area and the whole clean area can be avoided, which facilitates the cleanness of the pharmaceutical processing environment to meet the standard requirements in the Chinese GMP Version 2010.
