<p>The interior of a nozzle (7) is provided with an air channel (12) and two-system cleaning-fluid channels (11a, 11b), and the air channel (12) is further bifurcated into two-system tip sections (14a, 14b). A secondary tank (13) is further provided upstream of the cleaning-fluid channels. The tip section of the cleaning-fluid channel (11a) and the tip section (14a) of the air channel (12) converge, and the tip section of the cleaning-fluid channel (11b) and the tip section (14b) of the air channel (12) converge. Consequently, supplying compressed air to the air channel (12) causes the creation of negative pressure in the secondary tank (13) as a result of the airflow; hence, it is possible to make the cleaning fluid into a mist and aspirate the same, and to clean the lens surface (1a) of the camera by mixing the cleaning-fluid mist and the compressed air. Furthermore, it is possible to reduce the amount of cleaning fluid used by making the cleaning fluid into a mist.</p> |
