The invention provides a cleaning nozzle unit and an on-vehicle camera unit to improve the cleaning performance of a lens of a vehicle-mounted camera. The cleaning nozzle unit (4) has a plurality of injection ports (48) for injecting a mist-like cleaning liquid, which is obtained by mixing air and a cleaning liquid, to a spherical lens (8) of the vehicle-mounted camera (2). The cleaning nozzle unit (4) is configured in such a manner that each injection port (48) is disposed on the side of the lens (8) bisected by a line passing through the apex (O) of the lens (8) when the lens (8) is viewed from the front. The mist-like cleaning solutions ejected from the ejection openings (48) are caused to collide with each other at predetermined locations on the surface (8A) of the lens (8).
本发明提供清洗喷嘴单元及车载摄像头单元,以谋求车载摄像头的透镜的清洗性能的提高。清洗喷嘴单元(4)具有将空气与清洗液混合而成的雾状的清洗液向车载摄像头(2)的球面状的透镜(8)喷射的多个喷射口(48),其中,该清洗喷嘴单元(4)构成为,所述各喷射口(48)在正面观察所述透镜(8)时配置在以通过所述透镜(8)的顶点(O)的线将所述透镜(8)二等分的一侧,使所述喷射口(48)各自喷射的所述雾状的清洗液彼此在所述透镜(8)的表面(8A)的规定部位碰撞。
