Abstract

EDIT 13/01/15 Air passage and two lines of cleaning fluid path and is provided in the nozzle and the air passage is split into two of the far end. A secondary tank is provided at the source of the cleaning fluid path. the far end of the route cleaning liquid and the far end of the air passage is converged. When compressed air is supplied to the air passage, the resulting air flow causes the interior of the secondary tank to have negative pressure, so the cleaning fluid can be treated as a mist. and is vacuumed and the cleaning liquid in the form of aerosol and compressed air is mixed, so it is possible to clean the lens surface. and reduce the amount of cleaning fluid clean used down ---------------------------------------------------- ---------------------------------------- The air passage (12) and the two lines of the cleaning fluid path (11a) and (11b) have been The arrangement is provided in the nozzle (7) and air passage (12) is separated into two wires of the far end (14a) and (14b). available at the origin of the route cleaning fluid. Then, the far end of the cleaning fluid path (11a) and the far end (14a) of the air passage (12) are converged. and the end The far end of the cleaning fluid path (11b) and the far end (14b) of the air passage (12) are converged, therefore, when compressed air is supplied to the air passage (12), the resulting air flow will cause the inside of the secondary tank (13) to have negative pressure, so the cleaning liquid can Can be made in the form of a mist. and get sucked and cleaning liquid in The mist form and the compressed air are mixed, so it is possible to clean the lens surface (1a) of the camera by keeping the cleaning liquid in the form of a mist. Reduce the amount of cleaning fluid used.
