[0025] The technical solutions in the embodiments of the present application described above have at least the following technical effects or advantages: Since the self-acting air compressor is mainly composed of the boosting system 100, the pressure recovery system I 200, the pressure recovery system II 300, the pressure recovery system III 700, and the pressure re-recovery system 400, the pressure recovery system I 200, the pressure recovery system II 300, the pressure recovery system III 700, and the pressure re-recovery system 400 recover and reuse the gas energy released outward when the boosting system 100 discharges, boost pressure and inhale air, and can complete gas compression through the recovery and utilization of the energy of the high-pressure gas when it releases pressure.

[0034] A self-acting air compression method in this embodiment: Open the pressure relief valve of the pressure tank or air pump of the reserved air source 60, so that the air pressure in the pressure tank or air pump is conveyed to the starting component 110 through the air pressure pipeline. Refer to the attached Figure 2 , pressurize the air inlet of the solenoid valve 30 of the starting component 110, flow from the air inlet of the solenoid valve 30 to the air outlet of the solenoid valve 30, and then flow through the pipeline to the air inlet of the driving cylinder 10 to pressurize the piston in the driving cylinder 10. After the piston of the driving cylinder 10 is pressurized, it quickly moves downward. The piston of the driving cylinder 10 is firmly connected to the piston of the compression cylinder 20. During the downward movement of the piston of the driving cylinder 10, it pushes the piston of the compression cylinder 20 to move downward at the same time. The piston rod of the driving cylinder 10 is firmly connected to the piston rod of the compression cylinder 20; Therefore, when the piston of the driving cylinder 10 moves downward, it simultaneously pushes the piston of the compression cylinder 20 to move downward; During the downward movement of the piston of the compression cylinder 20, it will push and compress the gas in front of it, causing the gas volume to shrink, expand, and the pressure to increase. The space behind the piston of the compression cylinder 20 during its downward movement is in a vacuum or semi-vacuum state. Affected by the atmospheric pressure, the outside air will push open the one-way valve 40 of the upper air inlet of the compression cylinder 20 and enter the lower compression cylinder 20; When the pressurized gas in the compression cylinder 20 reaches a certain pressure value, it will push open the one-way valve 40 of the lower air outlet of the compression cylinder 20 and enter the low-pressure tank 500 through the pipeline; When the pistons of the driving cylinder 10 and the compression cylinder 20 reach the bottom end, the piston rods of the driving cylinder 10 and the compression cylinder 20 will touch the travel switch contacts, and then switch the air inlet direction through the solenoid valve 30 of the starting component 110 to supply air to the lower air inlet of the driving cylinder 10, while the upper air inlet starts to exhaust. The exhausted air pressure passes through the exhaust port of the solenoid valve 30 of the starting component 110 and flows through the pipeline to the air inlet of the solenoid valve 30 of the pressure boosting component 120. The air pressure flows from the air inlet of the solenoid valve 30 of the pressure boosting component 120 to the pipeline tee joint, and through the tee joint, it flows to the upper air inlet of the pressure boosting driving cylinder 11 and the upper air inlet of the pressure boosting compression cylinder 21 respectively, pressurizing the piston of the pressure boosting driving cylinder 11 and the piston of the pressure boosting compression cylinder 21 at the same time.

[0035] Since both the pressure boosting driving cylinder 11 and the pressure boosting compression cylinder 21 are sealed containers, and the pressure supply direction is the same as the movement direction of the piston, the pressure on the upper and lower piston surfaces is equal, but the pressure generated due to the size of the surface area is not equal. However, the pressures on the upper and lower pistons are in the same direction, and the two forces become a resultant force, that is, the sum of the pressure on the upper piston and the pressure on the lower piston is the downward force of the lower piston; Refer to the attached Figure 2 , the piston diameter of the pressure boosting driving cylinder 11 is 125mm, the piston diameter of the pressure boosting compression cylinder 21 is 100mm, the air pressure P is 6kpa, and the piston surface area S of the pressure boosting driving cylinder 11 上 = 122cm 2 , the piston surface area S of the pressure boosting compression cylinder 21 下 = 78.5cm 2, the pressure F borne by the piston of the boosting drive cylinder 11 上 =PS 上 =6×122 = 732 kg, the pressure F borne by the piston of the boosting compression cylinder 21 下 =PS 下 =6×78.5 = 471 kg, F 上 and F 下 The sum of is F 上 +F 下 =732 + 471 = 1203 kg; the pressure discharged from the lower exhaust port of the compression cylinder 20 is 10 kPa, and a total of 785 kg of pressure needs to be consumed, with a difference of 418 kg between the two forces. The reason is caused by two aspects. On the one hand, it is the exhaust resistance of the drive cylinder 10, and on the other hand, it is the insufficient resistance of the air outlet of the compression cylinder 20. In actual operation, it can be completed with 9 kPa; when the high-pressure gas generated by the boosting compression cylinder 21 reaches a certain pressure value, it will open the one-way valve 40 at the lower exhaust port of the boosting compression cylinder 21 and flow through the pipeline to the intake port of the solenoid valve 30 of the suction assembly 130 to pressurize the suction drive cylinder 12 of the suction assembly 130; after the piston of the suction drive cylinder 12 of the suction assembly 130 is pressurized, it moves downward, pushing the piston of the suction compression cylinder 22 downward. During the downward movement of the piston of the suction compression cylinder 22, it will push and compress the gas in front of it, reducing the gas volume, expanding, and increasing the pressure. When the pressurized gas in the suction compression cylinder 22 reaches a certain pressure value, it will open the one-way valve 40 at the lower air outlet of the suction compression cylinder 22 and enter the low-pressure tank 500 through the pipeline; The suction drive cylinder 12 of the suction assembly 130 exhausts, enters the intake port of the solenoid valve 30 of the next set of boosting assemblies 120 through the exhaust port of the solenoid valve 30 of the suction assembly 130, and through the outlet port of the solenoid valve 30 of the boosting assembly 120, the air pressure is respectively transported to the upper intake ports of the boosting drive cylinder 11 and the boosting compression cylinder 21 through the pipeline tee, simultaneously pressurizing the piston of the boosting drive cylinder 11 and the piston of the boosting compression cylinder 21. This boosting assembly 120 repeats the actions of the previous set of boosting assemblies 120, and the high pressure generated is transported to the intake port of the solenoid valve 30 of the next set of suction assemblies 130. This suction assembly 130 repeats the actions of the previous set of suction assemblies 130, and the discharged air pressure is transported to the adjacent next set of boosting assemblies 120. This boosting assembly 120 repeats the actions of the previous boosting assembly 120, and the high pressure generated is transported to the next set of adjacent suction assemblies 130. This suction assembly 130 repeats the actions of the previous suction assembly 130, and the pressure discharged by the suction drive cylinder 12 is transported to the solenoid valve 30 of the adjacent boosting assembly 120. This set of boosting assemblies 120 repeats the actions of the previous boosting assembly 120. In this way, boosting, suction, boosting, and suction are repeatedly cycled. According to the requirements, n groups are set in sequence until the requirements are met; among them, the high pressure of the last set of boosting assemblies 120 is recovered into the high-pressure tank 900; the above is the single-stroke description of this embodiment.

[0036] The return journey of this embodiment is described as follows: Refer to the appended drawings of the specification Figure 2-7 When the pistons of the driving cylinder 10 and the lower compression cylinder 20 of the starting component 110 run to the bottom end, the upper and lower piston rods of the driving cylinder 10 and the compression cylinder 20 will touch the travel switch contacts, controlling the solenoid valve 30 to cut off the air intake of the upper air inlet of the driving cylinder 10, and at the same time pressurize the lower air inlet of the driving cylinder 10. After the piston of the driving cylinder 10 is pressurized, it quickly makes an upward return movement. While the piston of the driving cylinder 10 moves upward, it pulls the piston of the compression cylinder 20 upward; during the upward movement of the piston of the compression cylinder 20, it needs to push the gas blocking in front of it, so that the volume of the gas is reduced, expanded, and the pressure is increased. When the pressure of the compression cylinder 20 reaches a certain value, it will push open the one-way valve 40 of the upper exhaust port of the compression cylinder 20 and be transported to the low-pressure tank 500 through the pipeline; When the pistons of the drive cylinder 10 and the compression cylinder 20 run to the top, the piston rods of the drive cylinder 10 and the compression cylinder 20 will touch the travel switch contacts. The travel switch controls the solenoid valve 30 to switch the air intake direction, cutting off the air intake of the lower air inlet of the drive cylinder 10, and at the same time inflating the upper air inlet of the drive cylinder 10, and the lower air inlet of the drive cylinder 10 begins to exhaust. During the upward movement of the piston of the compression cylinder 20, the space behind it is in a vacuum or semi-vacuum state. Under the influence of atmospheric pressure, the outside air will break through the one-way valve 40 of the lower air inlet of the compression cylinder 20 and enter the compression cylinder 20, waiting for the piston to return for compression. The exhaust gas from the lower air inlet of the drive cylinder 10 is delivered to the exhaust port of the solenoid valve 30 of the starting assembly 110. The air pressure is inputted from the air inlet of the solenoid valve 30 of the boosting assembly 120 through the air outlet of the solenoid valve 30, and is respectively delivered to the lower air inlet of the boosting drive cylinder 11 and the lower air inlet of the boosting compression cylinder 21 of the boosting assembly 120 through the pipeline through the pipeline tee, thereby pressurizing the pistons of the boosting drive cylinder 11 and the boosting compression cylinder 21 respectively; the air inlet of the boosting compression cylinder 21 is provided with a one-way valve 40, and the gas must pass through the one-way valve 40 to enter the boosting compression cylinder 21; after the boosting drive cylinder 11 and the boosting compression cylinder 21 are pressurized at the same time, they move upward at the same time, and the piston of the boosting compression cylinder 21 pushes the gas in front of it during the upward process, and its volume is reduced, and the gas expands. When the pressure in the boost and compression cylinder 21 reaches a certain value, the one-way valve 40 at the exhaust port of the boost and compression cylinder 21 will be opened, and the air will be transported to the air inlet of the solenoid valve 30 of the suction component 130 through the pipeline. The air pressure is transported to the air inlet of the suction drive cylinder 12 of the suction component 130 through the pipeline through the air outlet of the solenoid valve 30. At this time, the air pressure enters which of the upper and lower air ports of the suction drive cylinder 12 is automatically adjusted by the solenoid valve 30. Because the volume of the boost and compression cylinder 21 of the boost component 120 is not equal to the volume of the suction drive cylinder 12 of the suction component 130, the volume of the suction drive cylinder 12 of the suction component 130 is greater than the volume of the boost and compression cylinder 21 of the boost component 120, and the suction component 130 The movement frequency of the suction drive cylinder 12 is lower than the movement frequency of the boost compression cylinder 21 of the boost assembly 120. The suction drive cylinder 12 of the suction assembly 130 has a waiting time, but for the sake of explanation, the waiting time of the suction drive cylinder 12 of the suction assembly 130 is omitted here, and the action of the suction assembly 130 is directly explained; after the boost compression cylinder 21 of the boost assembly 120 delivers high pressure to the air inlet of the solenoid valve 30 of the suction assembly 130, the air pressure passes through the air outlet of the solenoid valve 30 of the suction assembly 130 and is delivered to the lower air inlet of the suction drive cylinder 12 of the suction assembly 130 through the pipeline. After the piston of the suction drive cylinder 12 is pressurized, it quickly moves upward, and at the same time drives the piston of the suction compression cylinder 22 to move upward;During the upward movement of the piston of the intake compression cylinder 22, the gas blocking its forward movement will be pushed and pressed, causing the gas volume to shrink, expand, and the pressure to increase. When the pressure of the compressed gas reaches a certain pressure value, it will push open the one-way valve 40 at the exhaust port of the intake compression cylinder 22 and be transported into the low-pressure tank 500 through the pipeline; When the space behind the piston in the air intake compression cylinder 22 is in a vacuum or semi-vacuum state during the upward movement of the piston, affected by the atmospheric pressure, the air outside the air intake compression cylinder 22 will, under the action of the atmospheric pressure, push open the one-way valve 40 at the lower air intake of the air intake compression cylinder 22 and enter the air intake compression cylinder 22 of the air intake assembly 130, waiting for the piston to return and push; when the pistons of the air intake driving cylinder 12 and the air intake compression cylinder 22 of the air intake assembly 130 run to the top, the piston rods of the air intake driving cylinder 12 and the air intake compression cylinder 22 will touch the contact points of the travel switch, and the travel switch controls the solenoid valve 30 to switch the air intake direction, that is, close the lower air intake of the air intake driving cylinder 12, and at the same time open the upper air intake and the lower exhaust port of the air intake driving cylinder 12. The exhaust gas from the lower exhaust port of the air intake driving cylinder 12 passes through the exhaust port of the solenoid valve 30 of the air intake assembly 130 and is transported through the pipeline to the air intake of the solenoid valve 30 of the next adjacent boosting assembly 120. The input air pressure passes through the air outlet of the solenoid valve 30 of the boosting assembly 120 and is respectively transported to the lower air intakes of the boosting driving cylinder 11 and the boosting compression cylinder 21 of the boosting assembly 120 through the pipeline tee by the pipeline. This boosting assembly 120 repeats the actions of the previous boosting assembly 120. The high-pressure gas generated by the boosting compression cylinder 21 of this boosting assembly 120 is transported to the next adjacent air intake assembly 130 through the pipeline, and this air intake assembly 130 repeats the actions of the previous air intake assembly 130; the exhaust gas of the air intake driving cylinder 12 passes through the exhaust port of the solenoid valve 30 of the air intake assembly 130 and is then transported through the pipeline to the air intake of the solenoid valve 30 of the adjacent boosting assembly 120. The air pressure passes through the air outlet of the solenoid valve 30 and is respectively transported to the lower air intakes of the boosting driving cylinder 11 and the boosting compression cylinder 21 through the pipeline tee by the pipeline, pressurizing the pistons of the boosting driving cylinder 11 and the boosting compression cylinder 21 respectively. This set of boosting assemblies 120 repeats the actions of the previous boosting assembly 120. The high-pressure gas discharged from the upper exhaust port of the boosting compression cylinder 21 is transported through the pipeline to the air intake of the solenoid valve 30 of the next adjacent air intake assembly 130, and this air intake assembly 130 repeats the actions of the previous air intake assembly 130; the air pressure discharged from the air intake driving cylinder 12 passes through the exhaust port of the solenoid valve 30 of the air intake assembly 130 and is transported to the air intake of the solenoid valve 30 of the next adjacent boosting assembly 120. The input air pressure passes through the air outlet of the solenoid valve 30 of the boosting assembly 120 and is respectively transported to the pistons of the boosting driving cylinder 11 and the boosting compression cylinder 21 through the pipeline tee by the pipeline, repeating the actions of the previous boosting assembly 120; the high-pressure gas discharged from the upper exhaust port of the boosting compression cylinder 21 is transported through the pipeline to the air intake of the solenoid valve 30 of the next adjacent air intake assembly 130, and this air intake assembly 130 repeats the actions of the previous air intake assembly 130. In this way, boosting, air intake, boosting, and air intake are repeatedly cycled. According to the requirements, n groups are set in sequence until the requirements are met; the high-pressure gas discharged from the exhaust port of the boosting compression cylinder 21 of the last set of boosting assemblies 120 is transported to the high-pressure tank 900 through the pipeline.
