Technical Field
[0001] The invention relates to the technical field of oxygen concentrators, in particular to a pressurized high-power oxygen concentrator and an assembly method thereof. Background Art
[0002] Oxygen generator is a highly efficient air separation equipment, which extracts oxygen from the air through advanced technology, using molecular sieve pressure swing adsorption (PSA) or cryogenic separation technology, and can continuously and stably provide high-purity oxygen. The boosted high-power oxygen generator mainly uses pressure swing adsorption (PSA) technology to produce oxygen. The inhaled atmospheric pressure air is raised to a higher pressure through an air compressor to provide sufficient driving force for the subsequent pressure swing adsorption (PSA) process. The air first passes through the inlet filter to remove dust particles, and then is boosted to a pressure of 3~4bar by the air compressor, so that components such as oxygen and nitrogen in the air can be separated under pressure; During the use of the existing pressurized high-power oxygen concentrator, in order to ensure that the high-power oxygen concentrator has a strong oxygen production capacity, air that can increase the pressure of ordinary atmospheric air to a higher pressure needs to be placed inside the oxygen concentrator. Therefore, the greater the power of the oxygen concentrator, the greater the working power of the air compressor inside the oxygen concentrator for compressing the air. As a result, the mechanical vibration generated by the pressurization work of the air compressor in the pressurized high-power oxygen concentrator is relatively large, which is easy to generate large noise and easily affect the physical and mental health of the staff. Therefore, in view of the above problems, a pressurized high-power oxygen concentrator and an assembly method thereof are proposed. Summary of the invention

[0005] As a further optimization of the present invention, the number of the fixing columns and the number of the shaft columns are both four, and the fixing columns and the shaft columns are arranged in groups of two on the front and rear sides of the chassis respectively, and the fixing columns are arranged above the shaft columns.
[0006] As a further optimized content of the present invention, wherein: the movable frame is arranged on the outside of the shaft column, the inner side of the movable frame is slidably connected with a transmission rod, and the movable frame slides on the inner side of the fixed frame.
[0007] As a further optimization of the present invention, there are two flat plates, which are symmetrically arranged on the left and right sides of the movable frame, the flat plate is arranged above the fixed frame, and the flat plate is arranged directly below the control rod.
[0008] As a further optimization of the present invention, the control rod rotates around the axis of the shaft column, two transmission rods that are in the same plane and parallel to each other are fixedly connected to the outside of the control rod, and the control rod is engaged with the limiting hook.
[0009] As a further optimization of the present invention, the limiting hook rotates outside the fixed shaft, there are four limiting hooks in total, and the limiting hooks are symmetrically arranged in groups of two on the upper sides of the two flat plates.
[0010] As a further optimization of the present invention, the piston ring slides inside the fixed frame, and the cross-sections of the piston ring and the rubber gasket are both in the shape of a "U".
[0011] As a further optimization of the present invention, a plurality of anti-vibration springs are evenly distributed on the inner side of the fixing frame, and two air holes are provided on the inner side of the fixing frame, and the air holes are symmetrically arranged on both sides of the fixing frame.
[0012] As a further optimized content of the present invention, wherein: the fixing frame is closely attached to the outside of the chassis, the fixing frame is arranged below the shaft column, and the fixing frame does not contact the flat plate.
[0013] As further optimized content of the present invention, wherein: S1: Activation of the oxygen concentrator: Before using the pressurized high-power oxygen concentrator, the user uses his feet to exert a downward force on the control rods on both sides of the chassis at the same time, so that the control rods rotate with the axis of the shaft column outside the chassis as the center of the circle through the transmission rod, so that the transmission rods on the inner side of the moving frame exert a downward force on the moving frame, and then the moving frame exerts a tensile force on the traction spring fixed on the fixed column, and at the same time, the moving frame pushes the rubber gasket through the piston ring and the anti-vibration spring to gradually contact the plane contacted by the pad foot, and under the continuous force of the control rod, the anti-vibration spring is completely contracted, at this time, the rubber gasket is completely in close contact with the plane contacted by the pad foot, and under the continuous movement of the control rod, the chassis is passively moved in the direction away from the plane contacted by the pad foot, until the control rod moves to the position of the limiting hook, elastically squeezes the limiting hook, and enters under the bending hook of the limiting hook, so that the limiting hook restored under the restoring force of the torsion spring controls the position of the control rod, thereby releasing the downward force on the control rod, and the anti-vibration spring inside the fixed frame gradually recovers, so that the position of the chassis moves upward again relative to the rubber gasket; S2: During the operation of the pressurized high-power oxygen generator, the pressurizing device inside the oxygen generator starts working, causing the chassis body of the oxygen generator to vibrate. At this time, the chassis is fixed to the moving frame through the shaft column, the transmission rod, the control rod, the limiting hook and the plate, so that the chassis can transmit the vibration generated by it to the moving frame, and the moving frame drives the piston ring fixedly connected to it to slide inside the fixed frame. At the same time, the piston ring elastically compresses the anti-vibration spring inside the fixed frame to reduce the vibration generated by the chassis. When the piston ring slides inside the fixed frame, it continuously controls the gas inside and outside the fixed frame to enter and exit through the air hole, so as to play a certain damping role on the elastic change of the anti-vibration spring. S3: When the pressurized high-power oxygen concentrator is turned off, in order to ensure the long-term effective elastic performance of the anti-vibration spring, the foot of the oxygen concentrator needs to be re-contacted with the horizontal ground. At this time, a small amount of downward force can be applied to the control rod to disengage the control rod from the limiting hook, and then the limiting hook can be pushed outward to release the force on the control rod. At this time, the chassis can control the control rod to restore rotation under its own gravity, and when the foot and the rubber gasket are in the same horizontal plane, under the restoring force of the traction spring, the rubber gasket can continue to move upward to an appropriate position above the foot, so that the oxygen concentrator can be stably placed on the horizontal ground.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by means of the shock-absorbing spring, piston ring and rubber gasket, when the booster device inside the oxygen concentrator is working, the mechanical vibration generated by the oxygen concentrator can be transmitted to the inside of the fixed frame through the movable frame, and reduced by the piston ring and the shock-absorbing spring inside the fixed frame, so that the noise generated by the oxygen concentrator is reduced, thereby ensuring the physical and mental health of the staff; 2. In the present invention, the control rod, transmission rod and moving frame are arranged to make the oxygen concentrator passively lifted and suspended in the air, so as to play a defibrillation role on the whole oxygen concentrator, thereby effectively avoiding the influence of the vibration of the oxygen concentrator caused by the operation of the air compressor on the instrument pointer; 3. In the present invention, by providing the traction spring and the fixing column, when the oxygen concentrator is not working, the fixing frame can be pulled up and moved to the outside of the chassis to be suspended in the air, thereby ensuring that the vibration-proof spring inside the fixing frame has good elastic properties, so that the mechanical vibration generated by the subsequent use of the boosted high-power oxygen concentrator can be reduced.

The fixed frame 563 does not contact the flat plate 54, which can play a certain role in limiting the horizontal plane position of the movable frame 53; As a technical solution for further implementation of this plan, S1: Activation of oxygen concentrator: Before using the pressurized high-power oxygen concentrator, the user uses his feet to exert a downward force on the control rods 63 on both sides of the chassis 1 at the same time, so that the control rods 63 rotate with the axis of the shaft column 61 on the outside of the chassis 1 as the center of the circle through the transmission rod 62, so that the transmission rod 62 on the inner side of the moving frame 53 exerts a downward force on the moving frame 53, and then the moving frame 53 exerts a tensile force on the traction spring 52 fixed on the fixed column 51, and at the same time, the moving frame 53 pushes the rubber gasket 564 through the piston ring 561 and the anti-vibration spring 562 to gradually contact the plane contacted by the pad foot 4, and under the continuous force of the control rod 63, the anti-vibration spring 562 is pushed to the rubber gasket 564 to gradually contact the plane contacted by the pad foot 4.
