Air cleaning device

A cleaning device (10) for cleaning a cover lens (30) of a vehicle headlamp (20), wherein the cleaning device (10) is configured to generate at least one airstream (50) and to direct the airstream (50) towards the cover lens (30), wherein the cleaning device (10) comprises:

• at least one air stream device (60), each of which is configured to generate at least one airstream (50) in an airflow direction (X), wherein each air stream device (60) comprises:
• an air chamber (100) having an inlet (110) for receiving air, a spreading section (120) for spreading the received air, a homogenization section (130), and a nozzle (140) for outputting the received air in the airflow direction (X) and forming the respective airstream (50),
• wherein the spreading section (120) comprises at least one guide channel (121) from the inlet (110) of the air chamber (100) transversely to the airflow direction (X) and comprises a channel output (122), wherein the guide channel (121) is configured to spread the received air transversely to the airflow direction (X) and to guide the received air to the homogenization section (130) of the air chamber (100),
• wherein the homogenization section (130) is configured to receive the spreading air via the separate channel output (122) of the guide channel (121) and to provide that the spreading air is uniform along the nozzle (140) of the air chamber (100),
• wherein the at least one air stream device (60) is formed by the combination of the following components:
• a main component (200) comprising the inlet (110), a part of the spreading section (120), a part of the homogenization section (130), and a part of the nozzle (140) of the air chamber (100) of each air stream device (60),
• a separation component (300) comprising a part of the spreading section (120) and a part of the nozzle (140) of each air chamber (100), wherein the separation component (300) is arranged on the main component (200) in a way that the main component (200) in combination with the separation component (300) form the spreading section (120) of each air stream device (60), and
• a cover component (400) comprising a part of the homogenization portion (130) and a part of the nozzle (140) of each air chamber (100), wherein the cover component (400) is arranged on the separation component (300) and the main component (200) in a way that the cover component (400) in combination with the main component (200) and the separation component (300) form the homogenization section (130) and the nozzle (140) of each air stream device (60),
• wherein the separation component (300) arranged between the main component (200) and the cover component (400) is configured to separate the main component (200) and the cover component (400) in a way so that a gap extending transversely to the airflow direction (X) between the main component (200) and the cover component (400) is formed, which gap defines the nozzle (140) of each air chamber (100), and
• wherein the main component (200) has an abutment portion (210), wherein the separation component (300) is disposed on the abutment portion (210) of the main component (200), wherein the at least one air stream device (60) is separated by a bridge (211) consisting of a part of the main component (200) and the separation component (300).
