[0028] See also Figure 1 , Figure 3 , Figure 4 , Figure 7A pump component 10 is installed on one side of the composite flushing component 9, and the pump component 10 is fixedly sleeved on the inside of the other side of the chassis 2. The interior of the pump component 10 includes a cleaning liquid box 101, a small water pump 102, a suction tube 103, an infusion tube 104 and two branch pipes 105.

[0029] Working principle: After the whole device has been used for a period of time, the brake stepper motor 71 inside the flip component 7 is started, and then the output end of the brake stepper motor 71 drives the two mounting frame plates 73 and the two external auxiliary lenses 8 to rotate 180 degrees clockwise through the second T-bar 72, and then the operation is stopped. At this time, the positions of the two external auxiliary lenses 8 are swapped. The used external auxiliary lenses 8 rotate and move between the two hollow circular plates 92 inside the composite flushing component 9, and the unused external auxiliary lenses 8 are moved to the front of one end of the video surveillance device 1 and aligned with the video surveillance device 1. The unused external auxiliary lenses 8 During the flipping process, the sealing component 6 is gradually squeezed to compress and deform the compression spring 64 inside the sealing component 6, and the elastic ring strip 61 is fitted to the inner side of the make way groove 5. The first T-shaped rod 63 makes a make way movement inside the make way groove 5. When the unused outer auxiliary lens 8 stops, the compression spring 64 applies a restoring elastic force to the first T-shaped rod 63, and then the first T-shaped rod 63 pushes the elastic ring strip 61 to fit tightly with the reverse side of the unused outer auxiliary lens 8. At the same time, the negative pressure hole 62 is deformed under pressure to discharge the space inside itself and forms a negative pressure adsorption effect with the reverse side of the unused outer auxiliary lens 8.

[0030] After the two external auxiliary lenses 8 are swapped, the unused external auxiliary lenses 8 isolate and protect the lens inside the video surveillance device 1 from environmental dust while not interfering with the shooting inside the video surveillance device 1. As for the used external auxiliary lenses 8, the small water pump 102 is started, and the small water pump 102 pumps the cleaning liquid inside the cleaning liquid box 101 to the inner side of the two branch branches 105 through the suction tube 103 and the infusion tube 104, and then enters the inside of the two hollow circular plates 92, and then sprays to the front and back sides of the used external auxiliary lenses 8 through the spray holes 93 set on the inner walls of the two hollow circular plates 92 for washing, so as to wait for subsequent replacement and use;

[0031] When the outer auxiliary lens 8 passes through the dustproof plate 11 in a clockwise direction, the outer auxiliary lens 8 presses against the two dustproof plate bodies 111 inside the dustproof plate 11, so that the two dustproof plate bodies 111 are turned 90 degrees by means of the rotating sleeve 112 and the rotating shaft 113 connected to them respectively, thereby providing a space for making way. After the outer auxiliary lens 8 leaves the interior of the composite flushing component 9, the two dustproof plate bodies 111 are reset by the reset spring pieces 114 connected to them respectively, ready for next use.
