[0039] The power shaft 10 is sleeved in the through hole opened on the support block 12, and a retaining ring 20 is fixedly sleeved on the power shaft 10, and the retaining ring 20 is fitted in the annular cavity opened in the support block 12. The rising wiping ring 18 includes a support ring 34 and an annular sponge sleeve 35. The support ring 34 is in the shape of an annular shell, and the support ring 34 passes through the lifting plate 37. One end of the first tracheal cavity 40 extends into the inner cavity of the support ring 34. A plurality of evenly distributed air holes 36 are arranged on one side of the shell of the support ring 34. The outer fixed sleeve of the support ring 34 is an annular sponge sleeve 35. Figure 4 and Fig.13 It is understood that the air hole 36 is arranged on the shell of the support ring 34 facing away from the camera 1, and the opening direction of the air hole 36 is facing away from the lens part of the camera 1, so that the air flow discharged from the support ring 34 drives the small water droplets retained in the annular sponge sleeve 35, forcing the water droplets to splash away from the camera 1. The air storage device 8 includes an air cylinder 47, a third spring 48 and a piston disk 49. The air cylinder 47 is cylindrical and one end of the cylinder is fixedly buckled on the control body 5, and the edge of the other end of the cylinder is inverted. The air cylinder 47 is movably sleeved with a third spring 48 and a piston disk 49.

[0040] The toggle assembly 17 includes a second spring 27, a guide column 28, a control seat 29 and a one-way valve 30. The control seat 29 is a T-shaped block. Two symmetrically distributed through holes are provided on the control seat 29. The control seat 29 is arranged in a T-shaped groove provided on the outer wall of the cylinder of the control body 5. The one-way valve 30 and the guide column 28 are arranged in the through hole of the control seat 29. One end of the guide column 28 is fixed on the control body 5. The second spring 27 is sleeved on the guide column 28. The second spring 27 is padded between the control body 5 and the control seat 29. The one-way valve 30 includes a breathable disk 31, a capillary 32 and a rubber pad 33. The breathable disk 31 is fixed on the inner wall of the through hole of the control seat 29.

The capillary 32 runs through the middle of the rubber pad 33.

[0041] The control valve 13 includes a positioning cylinder 50, a movable ball 51 and a J-shaped column 52. The positioning cylinder 50 is fixed on the control body 5. A movable ball 51 is provided on one side of the positioning cylinder 50. A plurality of evenly distributed J-shaped columns 52 are arranged around the movable ball 51. One end of the J-shaped column 52 is fixed on the positioning cylinder 50.

[0042] The power assembly 14 includes an interception cylinder 53, a fourth spring 54 and a lifting column 55. One end of the fourth spring 54 contacts the interception cylinder 53, and the interception cylinder 53 is fixed to the control body 5. The other end of the fourth spring 54 contacts the lifting column 55. One end of the lifting column 55 extends into the arc surface slot 22. The lifting column 55 is cylindrical and one end of the column is hemispherical. Fig.15It is understood that the way the airflow passes through the control valve 13 is that the airflow lifts up the movable ball 51, and then passes through the gap between the positioning tube 50 and the movable ball 51. The reverse flow of the airflow will drive the movable ball 51 to block the positioning tube 50. In this way, the external gas enters the control tube cavity 23 through the ports on both sides of the control tube cavity 23, and then rises and is injected into the third tracheal cavity 43. The repeated lifting and lowering movements of the lifting column 55 cause the airflow in the control tube cavity 23 to flow.

[0043] Working principle: a steam sensing mechanism, a power supply and a motor drive mechanism in the prior art are arranged at one end of the fan assembly 2. When the steam coming toward the face is sensed, the steam sensing mechanism controls the power supply to supply power to the motor drive mechanism. The motor drive mechanism is connected to the fan assembly 2 to control the rotation of the power shaft 10, thereby driving the fan 11. The fan 11 rotates to blow the oncoming steam to prevent the steam from blowing onto the lens of the camera 1. If the steam sensing mechanism senses that the steam is too thick, it will increase the control of the power supply, control the motor power to increase, and finally control the rotation speed of the power shaft 10. The speed of the fan 11 increases, and the steam is blown forcefully. In addition, the power device 4 is triggered to work, which eventually causes the wiping ring 18 to swing back and forth. During the swinging process, the wiping ring 18 wipes the lens of the camera 1 to prevent the lens from being atomized. Specifically, the speed of the control cylinder 3 increases, and the centrifugal force increases the control of the brake assembly 19, that is, the centrifugal column 25 is gradually thrown out. After the centrifugal column 25 extends out from the control cylinder 3, it will hit the toggle assembly 17, thereby causing the control body 5 to swing. After the toggle assembly 17 is knocked back into the control body 5, the control body 5 will swing back and forth for a period of time. The control body 5 drives the main board 7, and then controls the wiping ring 18 to swing. It takes a certain amount of time for the toggle assembly 17 to extend out of the control body 5 again, because the second spring 27 elastically pushes the control seat 29, and gas needs to be supplemented to the one-way valve 30 and the guide column 28 during the process. The gas is discharged through the jacking rubber pad 33 and then through the through hole on the breathable disk 31. The air flow back cannot pass through the one-way valve 30, but through the gap between the guide column 28 and the through hole of the control seat 29. In this way, the toggle assembly 17 is delayed to extend out of the control body 5. During the swinging process of the control body 5, the power assembly 1 4 is moved by the support shaft 6, and the power assembly 14 performs reciprocating motion. The power assembly 14 sinks into the control tube cavity 23 and squeezes the gas in the control tube cavity 23 into the gas storage device 8. The power assembly 14 reverses and the external gas is sucked into the control tube cavity 23. In this cycle, the gas is gradually injected into the gas storage device 8, that is, the air pressure pushes up the piston plate 49, and the piston plate 49 moves to press the third spring 48. The reason for this is that the main board 7 cannot realize air flow when it is shaking, because the movable plate 38 drives the sealing door plate 44 during the reciprocating swing in the fan-shaped plate cavity 41.The tube cavity on the sealing plate 44 and the tube cavity on the lifting plate 37 are not connected. Only the lifting plate 37 is completely upright and stationary. The movable plate 38 is just stationary above the sealing plate 44. In addition, the gas in the control tube cavity 23 is injected into the third air tube cavity 43, and then injected into the T-shaped tube cavity 46, and then diffused into the fan-shaped plate cavity 41 through the second air tube cavity 42, and then injected into the support ring 34 through the first air tube cavity 40. During the reciprocating swing of the wiping ring 18, the water on the camera 1 lens is sucked into the annular sponge sleeve 35 and evenly diffused in the annular sponge sleeve 35. Several air flows are sprayed from the support ring 34. The gas comes from the gas stored in the gas storage device 8. The air flow passes through the annular sponge sleeve 35. In this way, the air flow is sprayed to take away the moisture adsorbed in the annular sponge sleeve 35, ensuring that the annular sponge sleeve 35 still has adsorption force on the water on the camera 1 lens. ,
