Problems solved by technology

[0002] For example, in the case of an on-vehicle camera mounted on the rear of the vehicle to capture surrounding images to monitor vehicles driving behind the vehicle and surrounding obstacles, foreign matter such as water droplets and mud may adhere to the imaging surface when it rains. The condition of the lens, in this case, the surrounding image cannot be clearly captured

Abstract

A nozzle (7) is provided for cleaning the lens surface (1a) of a camera (1), the nozzle (7) being equipped with cleaning-fluid channels (11a, 11b) for guiding cleaning fluid to discharge ports (10a, 10b), and an air channel (12) for guiding compressed air to the discharge ports (10a, 10b). The end sections of the cleaning-fluid channels and the end section of the air channel are positioned so as to be near one another or converge with one another. When cleaning the lens surface (1a), the lens surface (1a) is cleaned by intermittently spraying the compressed air from the discharge ports, drawing in the cleaning fluid using the negative pressure generated by spraying the compressed air, and intermittently spraying the cleaning fluid from the discharge ports.

Description

technical field [0001] The present invention relates to, for example, a cleaning device for cleaning an on-vehicle camera installed at the rear of a vehicle to photograph the rear of the vehicle, and a cleaning method for the on-vehicle camera. Background technique [0002] For example, in the case of an on-vehicle camera mounted on the rear of the vehicle to capture surrounding images to monitor vehicles driving behind the vehicle and surrounding obstacles, foreign matter such as water droplets and mud may adhere to the imaging surface when it rains. The situation of the lens, in such a situation, the surrounding image cannot be clearly captured. Therefore, as an apparatus for cleaning the lens of an on-vehicle camera, for example, an apparatus described in Patent Document 1 is known. In the cleaning device disclosed in Patent Document 1, a cleaning liquid is blown onto the lens surface of the camera, and then high-pressure air is blown to remove foreign matter adhering to...
