When the present invention is in use, the ventilation equipment is energized, and the motor 10 will drive the impeller 11 to rotate, and use the principle of centrifugal force to draw the outside air into the air suction chamber 3 through the air inlet groove 4, and pass the air in the air suction chamber 3 through the air guide The slot 6 is pushed into the processing chamber 5, and the air is purified by the activated carbon layer and the HEPA filter layer in the processing chamber 5, and then enters the room through the air delivery tank 7 and the air delivery pipe 8, so as to achieve ventilation effect for the interior of the high-rise building. When inside the chamber 3, the large particles of dust in the air will be filtered by the filter screen 14. Since the ventilation equipment is installed at an outdoor high-altitude position, there will often be high-speed wind blowing past the ventilation equipment. According to Bernoulli's principle, a short period of time will form around the ventilation equipment. The negative pressure space makes the piston plate 16 in the chute 15 slide outward under the action of negative pressure. Under the action of the one-way valve, part of the air will enter the piston plate through the suction hole 20 during the outward sliding process of the piston plate 16. 16, after the negative pressure environment ends, the piston plate 16 slides back under the action of the first spring 18, and pushes the air that has just been inhaled into the air storage chamber 19 through the air guide hole 21. Whenever there is a high-speed When the air flow passes by, the piston plate 16 will slide back and forth, and the air storage chamber 19 will be inflated once.

When the ventilator is working, the circuit where the conductive spring 37 is located is also in the energized state. At this time, the detection element 41 located in the groove 40 can change the automatic resistance according to the relative humidity of the outdoor air. When the interval is suitable, the resistance value of the detection element 41 is small, and the current value passed by the conductive spring 37 is large, so that the shrinkage is large, and the slide bar 36 will be pulled to close the path of the flow tube 34, and the water in the water chamber 28 will not be able to pass through the flow tube. 34 is sprayed from the atomizing nozzle 39; when the outdoor air humidity is low and in dry weather, the resistance value at the detection element 41 is larger, the current value in the current circuit becomes smaller, and the shrinkage of the conductive spring 37 will be reduced.
