<p>The invention relates to a vehicle headlight cleaning apparatus. A main body of the cleaning apparatus is of a cylindrical structure and internally provided with a compression spring and a movable seal valve which is matched with the inner wall of a casing of the cleaning apparatus. Both ends of the spring are respectively fixed on the end part of the cleaning apparatus and a spring fixing seat of the movable seal valve. When cleaning solution flows in the cleaning apparatus through a cleaning solution inlet on a base, the pressure of the cleaning solution overcomes the spring force of the compression spring and drives a transmission guide rod, the movable seal valve and a nozzle to move together, and the transmission guide rod stops when moving to a limit position. The pressure of the cleaning solution increases continuously, then the movable seal valve is opened under the pressure of the cleaning solution, the cleaning solution sprays out through the transmission guide rod and the nozzle, and a complete cleaning circuit is formed. When cleaning is finished, the pressure of the cleaning solution disappears, the movable seal valve is closed under the function of the compression spring, the transmission guide rod retracts into the casing till to an initial position, and the whole cleaning is finished. The invention has small and exquisite appearance, light weight, reliable work and high cleaning efficient.</p> |
