Abstract: A cleaning device for cleaning a cover lens of a vehicle headlamp is configured to generate an airstream and direct it towards the cover lens. The cleaning device includes at least one air stream device (ASD) configured to generate at least one airstream in an airflow direction. Each ASD includes an air chamber having a spreading section for spreading the received air, a homogenization section for homogenizing the spread air, and a nozzle for outputting the received air in the airflow direction and forming the respective airstream. The spreading section includes a guide channel configured to spread the received air transversely to the airflow direction and to guide the received air to the homogenization section. The ASD is formed by: (i) a main component including parts of each of the spreading section, homogenization section, and nozzle of the air chamber of each ASD, (ii) a separation component including parts of the spreading section and nozzle, wherein the separation and main components form the spreading section of each ASD, and (iii) a cover component including parts of the homogenization portion and nozzle, wherein the cover, main, and separation components form the homogenization section and the nozzle of the ASD.
