Because two middle wind deflectors 206 and right side rotating plate 209 pass through horizontal thin connecting rod 3005 fixed connection, it is pushed by the gas thrust in left side air outlet 215 and rotates right, and at this moment, because left side wind deflector 203 is fixed with right side wind deflector 202, two middle wind deflectors 206 rotate right, cause the reduction of left side air intake 204, right side air intake 205 enlarges, and right side air intake 205 gets into gas more to because the rotation of middle wind deflector 206. The left air outlet 215 is enlarged, the thrust on the left air outlet is smaller and smaller, the size of the right air outlet 208 is unchanged, the thrust on the right air outlet is increased, and the right rotating plate 209 and the middle wind shield 206 are pushed to the left together. Set up flexible casing 210 on left side rotating plate 214, rather than telescopic link 211 in it, the setting of fixed third spring 212 that sets up between the two can rotate the pivot when rotating on the right side rotating plate 209 and the relative right side of middle part deep bead 206, pulling left side rotating plate 214 follows simultaneously and rotates, thereby prevent because the swing that left side air outlet 215 becomes too big and cause ends very fast when right side rotating plate 209 rotates with middle part deep bead 206, the extension wobbling time that can be better, the swing is more abundant, the clearance effect to rainwater on the rear-view mirror is better. The existence of the torsion spring 666 can enable the left rotating plate 214 to be reset quickly when air outlet is finished, and then the middle wind shield 206 and the right rotating plate 209 are reset through the reset of the third spring 212, so that preparation is made for the next cleaning.

2 rear end lower parts of gas storage box body are equipped with through-hole 3002, through-hole 3002 upper end is equipped with limit sleeve 3001, be equipped with filter core 3003 in through-hole 3002 and limit sleeve 3001, filter core 3003 is convenient for change, and enough black cigarette to producing in the tail gas filters: the through-hole sets up in gas storage tank 2 lower parts, makes filter core 3003 more convenient when changing, and limiting sleeve 3001 not only is convenient for filter core 3003's vertical installation, can also protect it can not collide the extrusion to slidable closing plate 20, and simultaneously, it can form spacingly to slidable closing plate 20, avoids it to touch its rear end wall in the gas storage tank internal motion process.

The working principle is as follows: when no gas exists in the gas storage box body 2, the lower end of the ventilation pipe 53 is attached to the inner end face of the tail gas conveying pipe 7, the tail gas is filled into the gas storage space 11 to push the slidable sealing plate 20 to move left, when the slidable sealing plate 20 moves left for a certain distance, the first push plate 157 is in contact with the slidable sealing plate 20, when the slidable sealing plate 20 is attached to the first push plate 157, the electrifyable plate 158 fixedly arranged at the head of the first push plate 157 is vertically attached to the two conductive pull pieces 159 in the conductive port 160, at this time, the first air pump 12 starts to work, air is pumped into the gas storage box body 2, and is combined with the tail gas in the gas storage box body 2, so that the high-temperature tail gas is properly cooled. The tail gas continues to be filled, when the first push plate 157 moves to the bottommost position, the fiber rod 154 passes through the limiting hole 188, the poking plate 102 is pushed backwards to the limiting block 161, the first air pump 12 is closed, and air pumping is stopped.

The first push plate 157 is driven to press backwards to compress the four first springs 900, and at the same time, the first sliding rod 155 is pushed into the hydraulic outer wall 103 to push the hydraulic fluid 800, so that the second sliding rod 51 rises in the second hydraulic outer wall 50, thereby driving the ventilation pipe 53 to rise, the exhaust gas can not be discharged upwards from the ventilation port 54, and the flexible hose 15 is compressed. The two second air pumps 10 are started, and the air in the air storage tank body 2 is respectively delivered to the rearview mirrors on the left and right sides of the automobile through the left and right air delivery pipes 1000.

When the air is delivered to the six air outlet square pipes 201 distributed in the second air delivery hose 213, due to the position relationship between the left air baffle 203, the middle air baffle 206 and the right air baffle 202, the left air inlet 204 is larger than the right air inlet 207, more air enters from the left air inlet 204, and the left air outlet 215 and the right air outlet 208 are opened at the beginning, so that the thrust of the air discharged from the left air outlet 215 is larger, and the thrust of the air discharged from the right air outlet 208 is relatively smaller. Because the two middle wind deflectors 206 and the right rotating plates 209 are fixedly connected through the transverse thin connecting rods 3005, the two middle wind deflectors 206 are pushed by the air thrust in the left air outlet 215 to rotate rightwards, at the moment, because the left wind deflector 203 and the right wind deflector 202 are fixed, the middle wind deflector 206 rotates rightwards, the left air inlet 204 is reduced, the right air inlet 205 is enlarged, more air enters the right air inlet 205, and the middle wind deflector 206 rotates. The left air outlet 215 is enlarged, the thrust on the left air outlet is smaller and smaller, the size of the right air outlet 208 is unchanged, the thrust on the right air outlet is increased, and the right rotating plate 209 and the middle wind shield 206 are pushed to the left together. The swing cleaning of the upper rainwater of the rearview mirror is realized. When the cleaning is finished, the two second air pumps 10 are closed, the cleaning is finished, and the air in the air storage box body 2 is automatically filled to the initial state to prepare for the subsequent cleaning.
