The invention relates to the technical field of camera cleaning, in particular to a camera cleaning nozzle, a camera cleaning device and an unmanned vehicle. The camera cleaning nozzle is arranged on the peripheral side of a camera and comprises a nozzle body, a cavity communicated with an air inlet pipeline is formed in the nozzle body, a first air outlet communicated with the cavity is formed in the nozzle body, and the extending direction of the first air outlet is tangent to the convex vertex of the camera; and at least part of the first air outlet is opposite to the camera. According to the camera cleaning nozzle, through the arrangement mode that the first air outlet is tangent to the convex points of the camera, flowing air sprayed out of the first air outlet can blow away attachments attached to the camera, meanwhile, an air curtain can be formed on the surface of the camera, more impurities are prevented from falling on the camera, meanwhile, the camera is effectively protected, and the service life of the camera is prolonged. The flowing gas is tangent to the surface of the camera, so that the friction force between the impurities and the camera can be reduced.
本公开涉及摄像头清洁技术领域,尤其涉及一种摄像头清洁喷嘴、摄像头清洁装置以及无人车。该摄像头清洁喷嘴,设置在摄像头的周侧,包括:喷嘴本体,所述喷嘴本体内开设有与进气管路连通的空腔,所述喷嘴本体上开设有与所述空腔连通的第一出风口,所述第一出风口的延伸方向与所述摄像头的凸起顶点相切,且至少部分所述第一出风口与所述摄像头正对设置。该摄像头清洁喷嘴,通过第一出风口与摄像头的凸点相切的设置方式,不仅能够使从第一出风口喷出的流动气体吹开摄像头上附着的附着物,同时也能在摄像头的表面形成气幕,防止更多杂质落在摄像头上,同时对摄像头形成有效地保护,这种流动气体与摄像头的表面相切也能减少杂质与摄像头之间的摩擦力。
