Description

Technical Field

[0001] This invention relates to a gas compressor, and more specifically, to a small gas compressor based on the kinetic energy of a reciprocating push-pull rod of an electric cylinder. Background Technology

[0002] A known gas compressor is a device that uses mechanical energy to compress gas. It mainly includes two categories: reciprocating piston compressors and screw compressors with dual rotor meshing. The piston compressor works by using a motor to drive a crankshaft. Multiple piston rods connected to the crankshaft drive a gas compression cylinder. Gas then flows from the first compression cylinder through pipes and check valves into the second compression cylinder, then through pipes and check valves into the third compression cylinder, then through pipes and check valves into the fourth compression cylinder, then through pipes and check valves into the fifth compression cylinder, and finally through pipes into the sixth compression cylinder before entering the equipment, thus obtaining multi-stage compressed gas. This method requires multiple compression cylinders to be integrated with the motor, making it inconvenient to use. It is commonly used in power equipment and military fields, and is also prevalent on ships, where the operating environments are diverse and unpredictable. To address the diverse application scenarios, the simplification, lightweighting, and miniaturization of gas compressor structures are becoming increasingly important.

[0003] The inventors in this case filed a patent application for a lightweight and portable gas compressor. After using it, they found that when using the prior application, the main unit and control system were separated from the compressor, which was inconvenient to control. Moreover, the hydraulic pipe A, hydraulic pipe B and air inlet pipe were prone to bending due to distance and turning angle, resulting in poor flow of oil and gas. The vehicle platform was also limited by the environment and could not reach the optimal destination.

[0030] Implement the small gas compressor based on the kinetic energy of the electric cylinder reciprocating push-pull rod described in this invention, combined with the attached... Figures 1 to 6 The method of using this invention involves using the first handle 8 and the second handle 14 to bring the invention to the location of use. Before use, the air inlet pipe 10 is connected to a gas source (e.g., a nitrogen cylinder, argon cylinder, carbon dioxide cylinder, or other inert gas cylinder), and the exhaust pipe 9 is connected to the equipment that needs to inject compressed gas. The power cord 15 is then used to connect to the power source. EtherCAT interface data cable The control terminal of 16 starts the servo motor of the present invention. At this time, the servo motor in the servo motor housing 17 drives the driven pulley, which drives the synchronous belt to rotate the driving pulley. The driving pulley is connected by a retaining ring and a nut, a bearing bush, a guide sleeve and a nut, which convert the torque transmitted by the screw in the sleeve rod into axial thrust. The push-pull rod connector 33 at one end of the screw drives the square tube to push and pull back and forth. At this time, the push of the square tube drives the positive Y-shaped plate 12 and causes the piston rod 4 of the three positive compression cylinders 23 to drive the piston to squeeze the three positive compression cylinders 23 synchronously. At this time, the reverse Y-shaped plate 2 also drives the three piston rods 4 synchronously to make the pistons of the three reverse compression cylinders squeeze the three positive compression cylinders synchronously.

[0031] The specific gas compression process is as follows:

[0032] The forward Y-shaped plate 12 is pushed by the square tube driven by the push-pull rod connector 33, causing the pistons of the first forward compression cylinder 41, the second forward compression cylinder 45, and the third forward compression cylinder 44 to push inward synchronously. At this time, the inert gas in the first forward compression cylinder 41 is forced into the first reverse compression cylinder 43 through the connecting pipe 6 and the one-way valve. At the same time, the inert gas in the second forward compression cylinder 45 is forced into the second reverse compression cylinder 46 through the connecting pipe 6 and the one-way valve. The inert gas in the third forward compression cylinder 44 is forced into the third reverse compression cylinder 46 through the connecting pipe 6 and the one-way valve. Inert gas is squeezed into cylinder 42; after the compression of the forward Y-shaped plate 12 is completed, the square tube begins to push the reverse Y-shaped plate 2 "the forward Y-shaped plate 12 begins to pull outward". At this time, the first forward compression cylinder 41 draws in inert gas from the inert gas bottle through the air inlet pipe 10 and the one-way valve. The inert gas in the first reverse compression cylinder 43 is squeezed into the second forward compression cylinder 45 through the connecting pipe 6 and the one-way valve. The inert gas in the second reverse compression cylinder 46 is squeezed into the third forward compression cylinder 44 through the connecting pipe 6 and the one-way valve. The compressed gas in the third reverse compression cylinder 42 enters the equipment through the exhaust pipe 9.

[0033] The one-way valve in this invention allows the inert gas to travel in one direction only. Specifically, the inert gas in the first forward compression cylinder 41 can only enter the first reverse compression cylinder 43, the inert gas in the first reverse compression cylinder 43 can only enter the second forward compression cylinder 45, the inert gas in the second forward compression cylinder 45 can only enter the second reverse compression cylinder 46, the inert gas in the second reverse compression cylinder 46 can only enter the third forward compression cylinder 44, the inert gas in the third forward compression cylinder 44 can only enter the third reverse compression cylinder 42, and the inert gas in the third reverse compression cylinder 42 enters the equipment.

However, it should be understood that after reading the above teachings, those skilled in the art can make various alterations or modifications to the scope of protection of the present invention. These equivalent forms also fall within the scope defined by the appended claims.
