The embodiment of the invention comprises the following steps: in the state that the headlamp 2 is not cleaned at the beginning, the protective cover 3 is completely positioned in the cover hole 4, the bent pipe 9 is completely shielded by the protective cover 3, and a space is reserved between the bent pipe 9 and the protective cover 3; the blocking piece 25 completely blocks the inner channel of the sliding tube 8; the outer sleeve 10 is contacted with the two clamping plates 12, so that the outer cylinder 7 cannot swing when the device is not influenced by external force, and the normal use of the device is ensured. The extrusion strip 23 is contacted with the inclined plane of the triangular block 15; the limiting plate 19 side is laminated with the vertical face of commentaries on classics piece 18, has restricted commentaries on classics piece 18 and round pin 16 rotation to restricted C type board 13 and visor 3's swing, prevented that other people from opening visor 3 from bumper 1 outside under artificial external force when this device does not wash work, reached the purpose of protection this device inner structure.

When the headlamp 2 needs to be cleaned, high-pressure water from the inside of the automobile flows into the three-way pipe 38 from the hose A39, the high-pressure water flows into the square tube 14 through the three-way pipe 38 and the hose C37, and the inclined end of the sliding block 32 is always in contact with the sliding tube 8 under the pushing of the high-pressure water. The high pressure water flows into the outer cylinder 7 through the three-way pipe 38 and the B hose 36, and the inner channel of the sliding pipe 8 is completely blocked by the blocking block 25, so that the sliding pipe 8 drives the bent pipe 9 and the extruding strip 23 to move towards the protective cover 3 under the pushing of the high pressure water, and the A spring 35 is stretched. The movable extrusion strip 23 extrudes the inclined surface of the triangular block 15, so that the triangular block 15 drives the limiting plate 19 to move towards the support frame 5 through the L-shaped plate 20, the limiting plate 19 is not attached to the vertical surface of the rotating block 18, the C spring 22 is compressed, and the bent pipe 9 is not contacted with the protective cover 3; when the extruding bar 23 moves to the tip of the triangular block 15, the compression amount of the C spring 22 reaches the maximum, and at this time, the bent pipe 9 contacts the protective cover 3, and the limiting plate 19 does not limit the rotation of the rotating block 18. Then, the sliding pipe 8 continuously pushed by the high-pressure water pushes the protective cover 3 to swing out of the bumper 1 through the bent pipe 9, the C-shaped plate 13 swings along with the protective cover 3, the C-shaped plate 13 drives the pin 16 to rotate, the volute spiral spring 17 is compressed, and the rotating block 18 rotates. When the sliding groove 28 of the moving sliding pipe 8 is located at the position of the square tube 14, the sliding block 32 is continuously pushed by high-pressure water, the inclined end of the sliding block 32 quickly extrudes the blocking block 25 to enable the blocking block 25 to quickly move downwards, when the blocking block 25 moves downwards to the limit position, the spring B27 is compressed to the limit, the round hole of the blocking block 25 is completely aligned with the inner through hole of the sliding pipe 8, the high-pressure water of the outer tube 7 can be sprayed out at high pressure through the sliding pipe 8, the bent pipe 9 and the spray head 24, and the high-pressure water sprayed out of the spray head 24. After the sliding block 32 enters the sliding chute 28, the non-inclined side surface of the sliding block 32 limits the sliding tube 8 to continuously extend outwards, the outward swing amplitude of the protective cover 3 reaches the maximum at the moment, the compression of the spiral spring 17 reaches the maximum, and the extension of the A spring 35 reaches the maximum; under the reset action of the C spring 22, the extrusion strip 23 is convenient to contact with the inclined surface on the other side of the triangular block 15 after passing over the tip of the triangular block 15.

After the headlight 2 is cleaned, the hose a 39 does not supply high-pressure water any more, so that the water pressure of the sprayed water drops instantaneously; the thrust on the sliding block 32 in the square tube 14 is greatly reduced, the blocking block 25 moves upwards to reset under the reset of the spring B27, and the blocking block 25 pushes the sliding block 32 to move upwards to reset along the square tube 14; similarly, when the slide tube 8 moves back under the return of the a spring 35, the slide groove 28 of the slide tube 8 presses the inclined surface of the slide block 32, and the slide block 32 is also moved upward to return under the force assistance. After the slide block 32 is reset to the initial position, the sliding tube 8 is continuously reset so that the inclined end of the slide block 32 is in contact with the outer surface of the sliding tube 8 again until the sliding tube 8 is reset to the initial position, and part of water in the outer cylinder 7 flows back to the hose A39 through the hose B36 and the three-way pipe 38 under the reset of the sliding tube 8; part of the water in the square tube 14 returns to the A hose 39 through the C hose 37 and the tee 38 under the reset of the slide 32. In the process that the extrusion strips 23 reset along with the sliding tube 8, the extrusion strips 23 extrude the inclined surfaces of the triangular blocks 15 to enable the triangular blocks 15 to move towards the support frame 5, the C springs 22 are compressed, the triangular blocks 15 drive the limiting plates 19 to move towards the support frame 5 through the L-shaped plates 20, and the positions of the limiting plates 19 cannot hinder the reset rotation of the rotating blocks 18; the C-shaped plate 13 drives the protective cover 3 to swing and reset under the reset of the volute spiral spring 17, and the protective cover 3 is still contacted with the bent pipe 9; when the extrusion bar 23 moves to the tip of the triangular block 15, the compression amount of the C spring 22 reaches the maximum, the bent pipe 9 is ready to be separated from the protective cover 3, the protective cover 3 swings to the initial position, the volute spiral spring 17 restores to the initial state, and the rotating block 18 resets and rotates to the initial position; as the extrusion strips 23 continue to return along with the sliding tube 8, the extrusion strips 23 are contacted with the corresponding inclined surfaces of the triangular blocks 15 until the extrusion strips return to the initial positions, and the triangular blocks 15 drive the limiting plates 19 to be attached to the vertical surfaces of the rotating blocks 18 again through the L-shaped plates 20 under the return of the C springs 22.
