The working principle is as follows: when the window shade is used, the outer protection structure is fixed on the outdoor wall of the window through the fixed foot stand 4, when the bad weather such as wind, sand and the like comes and the window needs to be shaded, the power supply of the driving motor 59 is switched on, the controller controls the electric stay 521 to extend, the telescopic shaft of the electric stay 521 pushes the fourth gear 510 to be meshed with the first worm 51 and drives the positive prism shaft 522 to slide towards the inside of the outer clamping shaft 523, the output shaft of the driving motor 59 is transmitted to the fourth gear 510, the fourth gear 510 drives the outer clamping shaft 523 through the positive prism shaft 522 and then transmits the outer clamping shaft 523 to the first clamping wheel 56 through the outer clamping shaft 523, at the moment, the first clamping wheel 56 drives the chain 58 to rotate around the second clamping wheel 311, the chain 58 also drives the third clamping wheel 72 to rotate, the third clamping wheel 72 drives the third gear 71 to rotate through the rotating shaft 74, because the third gear 71 in the first protection rod 7 is meshed with the clamping teeth 312, the third gear 71 rotates downwards along the latch 312 along with the rotation of the third catch wheel 72, since the third gear 71 in the second guard bar 6 is not engaged with the latch 312, and the rotating shaft 74 in the second guard bar 6 adjacent to the first guard bar 7 is latched above the U-shaped stopper 39, so that all the second guard bars 6 are latched on the top of the limiting groove 32 by the U-shaped stopper 39, at this time, the third gear 71 in the first guard bar 7 drives the U-shaped bar 75 to move downwards through the rotating shaft 74, when the tarpaulin 8 above the U-shaped bar 75 in the first guard bar 7 is pulled straight, the tarpaulin 8 pulls the U-shaped bar 75 in the second guard bar 6 adjacent to the first guard bar 7 to slide downwards, and the U-shaped bar 75 pulls the rotating shaft 74 to slide downwards, at this time, the U-shaped stopper 39 is compressed by the pressure of the rotating shaft 74, so that the U-shaped stopper 39 slides towards the inside of the limiting plate 35, and the second guard bar 6 adjacent to the first guard bar 7 slides downwards, the third gear 71 is meshed with the latch 312 and moves downwards together with the first protection rod 7, when the second protection rod 6 adjacent to the first protection rod 7 slides downwards, the other second protection rods 6 also start to slide downwards, but the U-shaped stop 39 is not stressed any more, the compressed return spring 310 pushes the U-shaped stop 39 to slide out of the limiting plate 35 again and clamp the rotating shaft 74 in the second protection rod 6 above, so as to prevent the other second protection rods 6 from sliding downwards, the actions are repeated until the tarpaulin 8 between the U-shaped rods 75 is straightened, so that the second protection rods 6 can move downwards one by one, the tarpaulin 8 at the bottom of the shell 1 is just straightened when the first protection rod 7 falls to the bottom of the convex groove 31, at the moment, the first protection rod 7 contacts the bottom plate 9 and completely shields the window, the pulley 73 in the first protection rod 7 extrudes the first reset switch 34 at the bottom of the convex groove 31, the first reset switch 34 controls the original electric stay 521 to reset to the original position, at the moment, the first protection rod 521 is no longer pulled to drive the worm screw 510, and the first reset switch 34 is no longer meshed with the first protection rod 521, and the first power transmission mechanism 5 is no longer driven by the worm screw 521; meanwhile, the exhaust mechanism 2 always keeps rotating, the driving motor 59 drives the first worm 51 to transmit the rotation to the belt wheel 25, the belt wheel 25 drives the belt 24, the belt 24 drives the fan 22 to rotate around the cross-shaped bracket 23, and indoor air is sucked to the outdoor through the exhaust pipe 21;

when the weather turns well and does not need to shade the window, the controller controls the electric stay 521 to shorten, the telescopic shaft of the electric stay 521 pulls the fourth gear 510 to mesh with the second worm 57, the positive prism shaft 522 slides towards the outside of the outer clamping shaft 523, the driving motor 59 drives the first worm 51 to rotate, and drives the second gear 54 to rotate through the first gear 53, so that the second worm 57 is driven by the second gear 54, the rotation directions of the second worm 57 and the first worm 51 are opposite, at this time, the fourth gear 510 drives the outer clamping shaft 523 to rotate reversely through the positive prism shaft 522, and then drives the first clamping wheel 56 to rotate reversely through the outer clamping shaft 523, at this time, the first clamping wheel 56 drives the chain 58 to rotate, the chain 58 drives the third clamping wheel 72 to rotate, the third clamping wheel 72 drives the third gear 71 to rotate through the rotating shaft 74, at this time, all the third gears 71 mesh with the clamping teeth 312 in the limiting groove 32, so that the third gear 71 drives the rotating shaft 74 to rotate upwards, at the moment, the first guard bar 7 and the second guard bar 6 move upwards at the same time, when the third gear 71 of the second guard bar 6 positioned at the top no longer engages with the latch 312, the second guard bar 6 stops moving upwards, at the moment, the tarpaulin 8 below the second guard bar 6 is not tightened again until the next second guard bar 6 moves upwards to contact with the previous second guard bar 6, at the moment, the pulley 73 positioned at the lower part pushes the pulley 73 positioned at the upper part, so that the rotating shaft 74 in the second guard bar 6 positioned at the upper part pushes the U-shaped stopper 39, and the return spring 310 is compressed, so that the second guard bar 6 positioned at the upper part is caught by the U-shaped stopper 39, and similarly, the second guard bar 6 positioned at the lower part is jacked up by the second guard bar 6 positioned at the lower part and caught by the U-shaped stopper 39 until the first guard bar 7 rises to the top of the latch 312, and all the second guard bars 6 are jacked into the limiting groove 32 above the U-shaped stopper 39, at this time, the rotating shaft 74 in the uppermost second protection rod 6 presses and contacts the second reset switch 37, the second reset switch 37 is pressed to control the electric stay 521 to reset and extend to the original position, at this time, the telescopic shaft of the electric stay 521 pulls the fourth gear 510 to be no longer engaged with the first worm 51, so that the external clamping shaft 523 is no longer transmitted to the first clamping wheel 56, at this time, the driving mechanism 5 no longer transmits power, then, the driving motor 59 is turned off, and the exhaust mechanism 2 no longer draws air outwards.
