When the air ventilation purification device is used for ventilation of an indoor, firstly, the ventilation machine body 1 is arranged at a wall, the two ends of the air inlet cavity 17 and the air outlet cavity 18 are simultaneously communicated with the indoor and outdoor, the air quality monitor 19 monitors the outdoor air quality in real time, when ventilation is needed and the outdoor air is fresh, the first rotary roller 12 and the second rotary roller 15 are driven by the transmission component to synchronously rotate, the exhaust fan blade 13 rotates along with the first rotary roller 12 under the support of the first fixing frame 11, outdoor air is extracted from the air inlet cavity 17 to enter the ventilation machine body 1, finally, the air extracted by the purification mechanism is purified and fed into the indoor, meanwhile, the blowing fan blade 16 rotates along with the second rotary roller 15 under the support of the second fixing frame 14, the indoor air is discharged from the air outlet cavity 18, when ventilation is needed and the air quality monitor 19 monitors the outdoor air turbidity, a large amount of the air is easily fed into the indoor at the moment, so that the indoor air quality is rapidly reduced, the time of the device is delayed, the outdoor air is restored to the set air quality to start ventilation when the set air quality is restored, the ventilation environment is different, the ventilation frequency is also reduced, and the ventilation frequency is further, the ventilation frequency is reduced when the ventilation mechanism is further cleaned; when the air-exhausting fan blades 13 and the air-blowing fan blades 16 are controlled to run, after the air quality monitor 19 monitors that the outdoor air quality reaches the standard, the output end of the servo motor 2 drives a single gear 21 to rotate, and the three gears 21 are synchronously connected through a chain 22, so that when the single gear 21 rotates, the other two gears 21 are driven to synchronously rotate, the first rotary roller 12 and the second rotary roller 15 synchronously follow the output end of the servo motor 2 to rotate, the air draft fan blades 13 and the air blowing fan blades 16 are controlled to rotate for ventilation;
When the outdoor air is extracted by the air extraction fan blades 13 to enter the indoor ventilation, as the outdoor wind direction is indefinite, the air inlet cavity 17 is fixed by the three-way pipe 3, the air blown in a plurality of directions can enter the air inlet cavity 17 from the direct-current cavity 31 and the two side flow cavities 32, and compared with a traditional pipeline, the three-way pipe 3 can drive the air extraction under the rated power of the air extraction fan blades 13, so that more air can enter the indoor rapidly, and the air inlet effect of the three-way pipe 3 is better than that of the traditional pipeline;
When ventilation is carried out on the indoor air, if a small amount of impurities are carried in the outdoor air, the first electric sliding block 4 slides on the inner wall of the ventilation machine body 1 and drives the first sliding plate 41 to slide down to the air inlet cavity 17, the two filter screens 42 are fixed on the inner wall of the first sliding plate 41 to doubly filter the small amount of impurities in the air, the impurities are reduced to enter the indoor space, and if the outdoor air carries a small amount of impurities, the two filter screens 42 are contained above the air inlet cavity 17 along with the first sliding plate 41, so that the ventilation effect is ensured; when ventilating the room, if a large amount of impurities are contained in the outdoor air, the two filter screens 42 slide on the air inlet cavity 17 to filter, the second electric sliding block 5 synchronously drives the second sliding plate 51 to slide to the sliding groove of the first sliding plate 41, so that the second sliding plate 51 is overlapped with the first sliding plate 41, the two filter screens 42 and the second sliding plate 51 play a role of triple filtration, and the impurities in the air are filtered more carefully by virtue of the small holes of the second sliding plate 51, if the outdoor air is too turbid, the second sliding plate 51 slides with the plurality of filter screens 42 to generate dislocation, the holes of the second sliding plate 51 block the filter screens 42 to realize the function of sealing the air inlet cavity 17, when the filter screens 42 filter the impurities in the air for a long time, part of impurities are easily attached to the outer walls of the filter screens 42, thereby influencing the filtering ventilation effect of the filter screens 42, the scraper 6 is fixed on the inner wall of the ventilating machine body 1 and is positioned on the outer wall of the first sliding plate 41, when the first electric sliding block 4 drives the filter screens 42 to slide upwards to reset, the semi-arc scraper 6 can be attached to the outer wall of the filter screens 42, thereby reducing the impurities attached to the outer walls of the filter screens 42, the blower blade 42 rotates along with the filter screens 13, the impurities attached to the blower blades 13 rotate along with the filter screens, and the impurities are reversely blown down from the filter screens 13, impurities falling down from the spatula can be blown out of the ventilation machine body 1;
When ventilating the room, the air pumped from the outside into the air inlet cavity 17 enters the inside of the double-pass pipe 7, the transmission component is provided with two power gears, if the air quality is good, the first power gear is started to increase the rotating speed of the air pumping fan blade 13, the extracted air enters the room from the two ends of the double-pass pipe 7 for ventilating, if the air quality is poor, the second power gear is started to reduce the rotating speed of the air pumping fan blade 13, one end of the double-pass pipe 7 is plugged by virtue of the matching component, the extracted air enters the room after being filtered and purified from the other end of the double-pass pipe 7, the air exchanging and purifying effects are achieved, and meanwhile, the air pipe 71 and the double-pass pipe 7 are arranged one by one, so that the original indoor air and the new air can be separated, and the condition that the new air is discharged is reduced; when the air quality is bad, the transmission component starts the first power to increase the rotation speed of the fan blade 13, the wind force generated by the rotation speed of the fan blade 13 is enough to blow up the blocking plate 92 to be matched with the rotating rod 91 to turn over and open one end of the double-pass pipe 7 on the connecting frame 9, the extracted air enters the indoor ventilation from both ends of the double-pass pipe 7 at the same time, the air inflow of one end of the double-pass pipe 7 at the blocking plate 92 is larger than the other end of the double-pass pipe 7, the ventilation effect is improved, when the transmission component starts the second power, the rotation speed of the fan blade 13 is lower than that of the fan blade 13, wind power generated by rotation of the first-gear power air suction fan blade 13 does not blow up the blocking plate 92 to turn over, so that the extracted gas is purified from 8 places and then discharged into a room, and the air quality of ventilation is improved;
When the blowing fan blade 16 stops rotating, the protective screen 93 is fixed on the inner wall of the ventilator body 1 and is positioned at the outlet of the exhaust cavity 18, the protective screen 93 can filter and block a large amount of impurities from entering the room, and when the blowing fan blade 16 rotates to exhaust indoor air, the scraping plate 94 scrapes the outer wall of the protective screen 93 along with the rotation of the second rotating roller 15, so that the adhesion of the impurities on the outer wall of the protective screen 93 is reduced.
