Patent attributes
Embodiments of a unified airflow system for ultraviolet disinfection devices are disclosed. One embodiment of the present disclosure includes a unified airflow assembly and a control unit. The unified airflow assembly provides a shared airflow passage between a UV source and an airflow accessory capable of extracting contaminants from a target surface using a suction airstream. The UV source may be fluidically disconnected from the airflow accessory. The unified airflow assembly may include at least one air restriction unit in the shared airflow passage for manipulating a suction airstream therein. The control unit may be configured to drive the at least one air restriction unit to restrict the suction airstream to only one of the UV source and the airflow accessory.
