Alternatively, the telescopic rod 52 and the sleeve 51 are formed into a hydraulic telescopic cylinder structure. The telescopic rod 52 is hydraulically controlled to extend out of the sleeve 51, and when the telescopic rod 52 is fully extended, the cleaning liquid provided by the liquid supply unit 59 is output under pressure, enters the central cavity 54 through the delivery pipe 55, then enters the communication pipe 56, and finally is sprayed out from the spray head 53 to the camera 3.

Preferably, as shown in fig. 1-2, when the telescoping rod 52 is in the retracted state, the outer surface of the shield panel 4 is flush with the outer surface of the mounting outer panel 1. The shielding plate 4 is a part of the installation outer plate 1, a through hole is arranged on the installation outer plate 1, and the shape and the size of the shielding plate 4 are consistent with those of the through hole. When the telescopic rod 52 is retracted, the shielding plate 4 is closed, and the outer surface of the shielding plate is flush with the outer surface of the installation outer plate 1, so that the outer surface of the installation outer plate 1 is flat when viewed as a whole, and the appearance is more beautiful.

Preferably, as shown in fig. 2-5, the liquid supply unit 59 includes an infusion pump 591 and a liquid storage chamber 592, a liquid inlet of the infusion pump 591 is communicated with the liquid storage chamber 592, and a liquid outlet of the infusion pump 591 is communicated with the delivery pipe 55. The infusion pump 591 is a power source for delivering the cleaning liquid. The infusion pump 591, when activated, delivers the cleaning fluid in the reservoir 592 into the delivery tube 55 and into the central cavity 54. The mode of using the transfer pump 591 is simple to operate, and the speed of conveying the cleaning fluid can be conveniently controlled by controlling the power of the transfer pump 591. Also, the delivery of cleaning fluid from the reservoir 592 to the spray head 53 and the return of cleaning fluid from the central cavity 54 to the reservoir 592 may be controlled by the forward and reverse rotation of the infusion pump 591.

The telescopic rod 52 is fitted over the outside of the delivery pipe 55 and can slide along the delivery pipe 55. The delivery tube 55 extends into the central cavity 54 and contacts the cavity wall of the central cavity 54. Thus, the cleaning liquid can directly enter the central cavity 54 without leaking into the sleeve 51, and the waste of the cleaning liquid is reduced. The transport pipe 55 also has a guiding function so that the telescopic rod 52 can move along a predetermined track.

Optionally, one end of the delivery tube 55 extends into the central cavity 54 and the other end extends out of the sleeve 51 to communicate with the liquid supply unit 59.

Preferably, as shown in fig. 2-4, the outer side of the telescopic rod 52 is protruded with a stop block 521, and the wall of the sleeve 51 is protruded with a stop 511. The outside of the telescopic rod 52 is sleeved with a buffer spring 57, one end of the buffer spring 57 is contacted with the limiting block 521, and the other end is contacted with the stop block 511. When the telescopic rod 52 is extended, the limiting block 521 presses the buffer spring 57 to compress it. The buffer spring 57 buffers the telescopic rod 52, so that the telescopic rod 52 is more stable when being extended. When the telescopic rod 52 is contracted, the compressed buffer spring 57 is restored to be deformed, and thrust is generated to push the telescopic rod 52 to be contracted.

Alternatively, the stopper 511 is provided on the end of the sleeve 51 near the spray head 53, and the stopper 521 is provided on the end of the telescopic rod 52 far from the spray head 53, so that the telescopic stroke of the telescopic rod 52 can be maximized. When the telescopic rod 52 extends, the moving distance of the telescopic rod 52 can ensure that the opening range of the shielding plate 4 is the largest, so that the spray nozzle 53 can be completely exposed and faces the camera 3. Of course, the limiting block 521 and the stopper 511 may be disposed at other positions as long as the stroke of the telescopic rod 52 can meet the requirement of opening the shielding plate 4.

A check valve 58 for blocking an opening between the first and second chambers 541 and 542 is provided in the first chamber 541. The first cavity 541 has a shorter length than the second cavity 542, and the cross-sectional area of the first cavity 541 is smaller than the cross-sectional area of the second cavity 542. The check valve 58 allows the cleaning solution to enter the first cavity 541 from the second cavity 542, and prevents the cleaning solution in the first cavity 541 from flowing back to the second cavity 542.

Preferably, as shown in fig. 2-4 and 6, the check valve 58 includes an elastic member 581 and a blocking block 582 extending toward the second chamber 542, the blocking block 582 being attached to an end of the elastic member 581. The elastic members 581 have compressed and extended states.

When the elastic member 581 is in a compressed state, the blocking block 582 opens an opening between the first and second cavities 541 and 542.

When the elastic member 581 is in an extended state, the blocking block 582 blocks the opening between the first and second chambers 541 and 542.

When the camera 3 needs to be cleaned and the liquid supply unit 59 supplies cleaning liquid to the cleaning device 5, the cleaning liquid is pressed from the liquid supply unit 59 into the second cavity 542, so that the blocking block 582 has a pushing force. This pushing force pushes the blocking block 582 to move, and the elastic member 581 is compressed by the force. Thus, the opening between the first and second chambers 541 and 542 is opened, and the cleaning solution enters the first chamber 541 and enters the spray head 53.

When the cleaning is completed, the cleaning liquid pushed by the pressure loss no longer applies a pushing force to the blocking block 582, and at this time, the elastic member 581 is changed from a compressed state to an extended state, so as to push the blocking block 582 to move towards the direction close to the second cavity 542, and finally to block the opening between the first cavity 541 and the second cavity 542. This arrangement allows the blocking block 582 to be automatically opened when cleaning fluid is delivered. Convenient operation and simple whole structure.

Preferably, as shown in fig. 6, the blocking block 582 is provided with a positioning slot 583 with an opening facing the elastic member 581, and an end of the elastic member 581 is located in the positioning slot 583. The elastic member 581 is clamped in a positioning groove 583, and the positioning groove 583 is used for limiting the specific position of the elastic member 581 connected to the blocking block 582, so that the blocking block 582 and the elastic member 581 cannot be loosened.

Preferably, as shown in fig. 1-3 and 7, a fastening seat 41 is disposed on an inner side of the shielding plate 4, a fastening groove 42 is disposed on the fastening seat 41, and the nozzle 53 is fastened in the fastening groove 42. The nozzle 53 is in interference fit with the slot 42. The shield plate 4 is connected to a shield plate flange 43 extending toward the inside of the mounting outer plate 1, and the shield plate flange 43 surrounds the outside of the head 53. The fixing base 41 defines a specific installation position of the spray head 53, and the shielding plate 4 serves as a support plate of the spray head 53, so that the stability of the spray head 53 is enhanced, and the spray head 53 does not shake when spraying the cleaning liquid. The fixing seat 41 prevents the nozzle 53 from falling off when the shielding plate 4 rotates. And the spray head 53 is matched with the clamping groove 42, so that the spray head 53 can be conveniently replaced when damaged.

The shield plate flange 43 extends inwardly from the edge of the shield plate 4. Most preferably, the shield flange 43 surrounds the spray head 53 on three sides. In this way, when the shutter 4 is opened and the head 53 discharges the cleaning liquid, the shutter flange 43 further reduces the influence of the wind on the head 53. But also can shield the spray nozzle 53 from dust and other impurities, thereby avoiding pollution, blockage or damage to the spray nozzle 53.
