As shown in fig. 14, 15, 16 and 18, when the high pressure fan injects air upwards, that is, when the high pressure fan blade rotates forwards, the external air enters the high pressure fan from the bottom of the pneumatic unit, the upward injected air flow enters the upper space, the air cushion expands and pushes the air film generation plate to move upwards, under the push of the high pressure air flow, the round ball in the air flow channel moves upwards and blocks the opening at the top of the air flow channel, so that the air is blocked in the upper space and cannot be discharged, as the air pressure increases, the air pressure in the upper space pushes the vent steel ball of the one-way valve to move downwards, so that the air in the upper space enters the lower space through the vent channel, the air bag inflates and expands to lift the whole pneumatic unit upwards, as the air in the lower space increases, the pressure in the lower space increases, and when the pressure exceeds the pressure value set by the pressure release valve, under the pushing of pressure, the pressure relief steel ball moves rightwards, so that the excessive partial pressure is discharged through the pressure relief channel and the pressure relief hole, the pressing force of the pressure relief spring on the pressure relief steel ball can be adjusted by adjusting the pressure relief screw, and the pressure relief value can be adjusted according to different weights of the heavy objects. The bracket that will carry the heavy object is placed on pneumatic unit, the bracket can be down-pressed the ball at airflow channel top, open airflow channel, high-pressure gas will be followed and is spouted in the gap between ball and the airflow channel open-top, form even 360 airflow ring, can enlarge the active area of air film, the reinforcing air current is to the supporting effect of bracket, meanwhile, because partial gas is discharged from airflow channel, atmospheric pressure in the upper portion space reduces, under the effect of ventilation spring resilience force, the steel ball upward movement of ventilating is stopped up the opening of passageway, make the inside pressure of gasbag unchangeable in the lower part space, guarantee the supporting effect of gasbag to pneumatic unit. If the air film generation plate of a certain pneumatic unit is just pressed by the bracket for a half area, the non-pressed ball can block the corresponding air flow channel, so that high-pressure air is sprayed out from a gap at the pressed ball, and the air pressure of the air sprayed out from the air flow channel where the ball pressed by the bracket is located can not be reduced.

As shown in fig. 17 and fig. 19, when the high pressure fan blows air downwards, i.e. when the blades of the high pressure fan rotate reversely, the air cushion is compressed and drives the air film generation plate to descend, when the air film generation plate descends to a position lower than the supporting blocks, the supporting blocks will prop against the bracket to ensure that the air film generation plate can leave the bottom of the bracket, and meanwhile, the air flow channel on the air film generation plate can smoothly suck air, because the inner wall of the bottom of the air flow channel is provided with a plurality of stoppers for preventing the round balls from falling off, a gap is left between the round balls and the bottom opening of the air flow channel, outside air can enter the high pressure fan from the top of the pneumatic unit, the ejector rod is pushed to move downwards in the descending process of the air film generation plate, the air ball is pushed downwards by the ejector rod, the air in the lower space can flow out from the air flow channel, the air in the air bag can be sucked away by the high pressure fan, and the air bag can contract, meanwhile, the outside air enters the high-pressure fan from the top of the pneumatic unit and is sprayed to the ground through the high-pressure fan, so that the pneumatic unit is suspended on the ground, and the pneumatic unit can be drawn out from the bottom of the bracket.
