Abstract
The invention relates to a self-cleaning optical housing arrangement comprising a first cylindrical shell, a shaft, a motor, a second cylindrical shell element, a cleaning pad, a shaft magnet and a cylinder magnet. The shaft magnet and the cylinder magnet are arranged in order to magnetically interact such that a rotation of the shaft causes the shaft magnet to exert a force on the cylinder magnet that further causes the second cylindrical shell element to rotate with the shaft. The cleaning pad will upon rotation of the shaft and the second cylindrical shell element, sweep across and thereby clean at least a part of the outer surface of the first cylindrical shell.

A self-cleaning optical housing arrangement comprising:
- a first cylindrical shell including a first transparent portion;
- a shaft arranged with a shaft axis of rotation along the first cylindrical shell central axis;
- a motor connected to the first cylindrical shell and to the shaft, where the motor is configured to rotate the shaft relative to the first cylindrical shell;
- a second cylindrical shell element arranged at least in part around the first cylindrical shell and configured to rotate around the first cylindrical shell, the second cylindrical shell element is provided with a second transparent portion configured to be at least in part aligned with the first transparent portion;
- a cleaning pad connected to the second cylindrical shell element, and arranged at least in part between the first cylindrical shell and the second cylindrical shell element so that it physically contacts the first cylindrical shell outer surface;
- a shaft magnet connected to the shaft;
- a cylinder magnet connected to the second cylindrical shell element;
- where the shaft magnet and the cylinder magnet are arranged in order to magnetically interact such that a rotation of the shaft causes the shaft magnet to exert a force on the cylinder magnet that further causes the second cylindrical shell element to rotate with the shaft;
- and
- where, the cleaning pad, upon rotation of the shaft and the second cylindrical shell element, sweeps across, and thereby cleans, at least a part of the outer surface of the first transparent portion.
