When the electric push rod 5 drives the light-transmitting top plate 1 to move upwards, the corresponding articulated shaft of the electric push rod 5 articulated with the light-transmitting top plate 1 drives the arc-shaped rack 26 to rotate upwards through the connecting plate 28, the arc-shaped rack 26 rotates to drive the fourth gear 25 to rotate, the fourth gear 25 rotates to drive the second gear 23 to rotate, the second gear 23 rotates to drive the third gear 24 to rotate, the third gear 24 rotates to drive the first rotating shaft 20 to rotate, the first rotating shaft 20 rotates to drive the first synchronizing wheel 21 to rotate, the first synchronizing wheel 21 rotates to drive the second synchronizing wheel 22 to rotate through the synchronous belt 14, the second synchronizing wheel 22 rotates to drive the corresponding first winding roller 12 to rotate, the first winding roller 12 rotates to drive the other three first winding rollers 12 to rotate through the first gear 13, namely, the four first winding rollers 12 rotate simultaneously, and the four first winding rollers 12 rotate to take back the connecting belt 30 wound thereon; when the electric push rod 5 drives the transparent top plate 1 to move downwards, the hinge shaft of the corresponding electric push rod 5 hinged to the transparent top plate 1 drives the arc-shaped rack 26 to rotate downwards through the connecting plate 28, and the four first winding rollers 12 are rotated through the transmission of the fourth gear 25, the second gear 23, the third gear 24, the first synchronizing wheel 21, the second synchronizing wheel 22 and the first gear 13, so that the connecting belt 30 is led out, and the connecting belt 30 is pulled by the filter screen 2 to extend outwards. The diameter of the third gear 24 designed by the invention is smaller than that of the first synchronous wheel 21, and the design can ensure that the first winding roller 12 can relatively rotate by a larger angle under the condition that the arc-shaped rack 26 rotates by a small angle, so that the situation that the filter screen 2 is not compensated by the connecting belt 30 due to the small swing angle of the electric push rod 5 is prevented.

The sticky hair tape 51 used in the device is manufactured by a method similar to that of a sticky hair device for cleaning clothes on the market, the specific manufacturing method of the sticky hair tape 51 is the prior art, and the technology can ensure that the sticking capability of the sticky hair tape 51 after being washed up by water cannot be reduced.

The specific working process is as follows: when the ventilation dustproof equipment designed by the invention is used, when ventilation is needed, the electric push rod 5 is controlled to extend, the electric push rod 5 drives the light-transmitting top plate 1 to be opened upwards, and the filter screens 2 on the four sides are pulled by the light-transmitting top plate 1 to extend outwards; after the four-side filter screen 2 extends out, the magnetic attraction strips 34 of the filter screen 2 rope attract each other to connect the four-side filter screen 2 together, so that the light transmission experience of indoor residents is enhanced by opening the light transmission top plate 1, and meanwhile, the ventilation performance is also ensured; and impurities in the wind are filtered through the four-side filter screen 2.

After long-time use, if dirt is found on the filter screen 2, the cleanliness of the blown air is reduced, and the transparent top plate 1 is opened and closed in a reciprocating manner through the electric push rod 5; when the four-side filter screen 2 is opened, the four-side filter screen is pulled out, and the sticky hair belt 51 is wound on the second winding roller 39; when the four-side filter screen 2 is closed, the four-side filter screen 2 is retracted, in the retracting process, the sticky hair belt 51 arranged on the four second winding rollers 39 winds towards the third winding roller 41, dirt on the four-side filter screen 2 is adsorbed on the sticky hair belt 51 in the winding process, when the four-side filter screen is opened again, the sticky hair belt 51 can take out the adsorbed dirt together, the dirt adsorbed on the sticky hair belt 51 is washed by high-pressure water sprayed by the spray head 46 arranged on the water shell 37, and meanwhile, dirt which is adsorbed on the sticky hair belt 51 and is not easy to wash down is scraped by the scraping strip 40 arranged in the mounting shell 35; the dirt on the sticky fur belt 51 is cleaned through high-pressure impact and scraping, and the cleaned dirt is communicated with the sewage and is discharged through the drain pipe 32; when the filter screen 2 is cleaned, the transparent top plate 1 is opened and closed in a reciprocating mode, so that the filter screen 2 is pulled out and retracted in a reciprocating mode, the hair sticking belt 51 adsorbs dirt on the filter screen 2 in a reciprocating mode, and a high cleaning effect is achieved.

If the transparent top plate 1 is opened in rainy days, the transparent experience of indoor residents is enhanced, and at the moment, in order to prevent rainwater from flowing into the indoor space through the filter screen 2, the switch controls the induction lock module 10 on the transparent top plate 1 and the induction lock block on the transparent side plate 6, so that the transparent side plate 6 is driven to be opened when the transparent top plate 1 rises and is opened, the periphery is blocked, and rainwater is prevented from entering; in the present invention, if the transparent side plate 6 is to be opened in a state where the transparent top plate 1 is opened, the transparent top plate 1 needs to be closed and then opened again.
