Detailed Description
It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The sensors such as the camera and the laser radar are easily affected by dust, rain and snow, muddy water, insect corpses and the like. For example, when the camera encounters rain, the lens becomes blurred due to rain adhesion, and the image may be distorted, so that all the images collected under normal conditions may not be necessarily collected. If dust and dirt exist on the surface of the laser radar, the laser emission and the laser receiving are shielded to generate missed detection and false detection barriers. Once the sensor is contaminated, the driving assistance function of the unmanned driving system or the like may be limited, and the automatic driving function may be disabled, thereby causing a risk of traffic accident. Therefore, the application designs a sensor cleaning device which can effectively treat pollutants outside optical sensors such as cameras, laser radars and the like, so that the sensor can effectively work in various environments.

Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
In addition, the terms "first", "second", etc. are used to define the components, and are merely for convenience of distinguishing the corresponding components, and unless otherwise stated, the terms have no special meaning, and thus should not be construed as limiting the scope of the present application.
The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and variations may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
