Abstract
The invention relates to a cover lens cleaning system comprising a cover lens () for closing an opening of a housing () as well as a cleaning device (), wherein the cover lens () is transparent, wherein the cleaning device () can apply an air flow for cleaning to an outer surface of the cover lens () via an air outlet (). The cleaning device has one or more drainage openings () leading into an outer space on a lower side (), via which any moisture or liquid such as water present in the cleaning device () can escape. A membrane element () is arranged above the at least one drainage opening () and is reversibly deformable and designed in such a way that in a first so-called ON state, in which the cleaning device () is pressurized with air, the membrane element () is deformed in such a way that the one or more drainage openings () are closed, and in a second so-called OFF state, in which the cleaning device () is not pressurized with air, the at least one membrane element () is deformed in such a way that the one or more drainage openings () are at least partially not closed.
