Description

Technical Field

[0001] The invention belongs to the technical field of oxygen generators, and in particular relates to a pressure swing adsorption oxygen generator. Background Art

[0002] The pressure swing adsorption oxygen generator is generally composed of two adsorption towers. After the pressure swing adsorption oxygen generator compresses the air, it adsorbs nitrogen and other gases in the air through the molecular adsorption plate to enrich the oxygen, and then flows out from the outlet and is stored in the oxygen buffer tank. Then the nitrogen adsorbed by the molecular adsorption plate is depressurized and released back to the atmosphere through the exhaust valve. During the process of depressurization and release of one adsorption tower, the other adsorption tower starts to produce oxygen, and the cycle continues. When producing oxygen, the air needs to be compressed and adsorbed, etc. However, since there will be some smaller dust in the air, this will cause dust to accumulate inside the oxygen generator during long-term use, which will affect its use. Therefore, a dust net will be set at the air inlet to block the dust. However, dust accumulates on the dust net, which will affect the air circulation over time. Summary of the invention

[0012] The beneficial effects of the present invention are as follows: 1. The present invention blocks dust in the air through a dustproof net. When the oxygen generator body vibrates during operation, the gear is driven to move, and then the rack is squeezed by the second spring component, so that the rack is always in contact with the gear and meshes with the gear.

[0013] 2. The present invention first absorbs water vapor in the air through the hygroscopic film in the inner cavity of the hygroscopic frame. When the base shakes, the card gear moves. At this time, when the amplitude of the card gear shaking is large, the card gear contacts the card block. At this time, the card block and the card gear are connected to drive the ball screw to rotate, thereby driving the heating plate to move downward. The positive electrode and the negative electrode are driven downward by the heating plate to contact the power-on plate in series, so that the heating plate is energized and heated, so that the hygroscopic film is heated and drained, thereby realizing automatic drainage of the hygroscopic film, and then there is no need to manually replace the hygroscopic film, which effectively prevents the hygroscopic film from having too much water inside and causing the inability to remove moisture, and keeps the air entering the oxygen generator body dry.

[0014] 3. The present invention absorbs the lateral vibration generated by the oxygen concentrator body through spring assembly three, and then absorbs the vertical vibration generated by the oxygen concentrator body through spring assembly four, thereby reducing the shaking of the oxygen concentrator body during operation, the collision with the fixing seat, and the noise generation.

[0019] like Figure 3 As shown, in one embodiment, a moisture absorption frame 17 is fixedly installed on the front side of the air intake pipe 6, a support plate 18 is fixedly installed in the inner cavity of the moisture absorption frame 17, a moisture absorption film 19 is fixedly installed on the top of the support plate 18, a reset coil spring 22 is fixedly installed on the bottom end of the air intake pipe 6, a card gear 23 is fixedly connected to the central axis of the reset coil spring 22, a ball screw 24 is fixedly installed on the top end of the card gear 23, a heating plate 25 is meshed on the surface of the ball screw 24, a clamping block 26 is fixedly installed in the middle of the fixed rod 16, the heating plate 25 is fixedly connected to the moisture absorption film 19, a positive electrode 32 and a negative electrode 33 are fixedly installed on the right side of the heating plate 25, and a power-on plate 34 is fixedly installed on the bottom end of the inner cavity of the moisture absorption frame 17; The working principle and beneficial effects of the above technical solution are as follows: the hygroscopic film 19 in the inner cavity of the hygroscopic frame 17 absorbs water vapor in the air. When the base 1 shakes, the card gear 23 moves. At this time, when the amplitude of the card gear 23 shaking is large, the card gear 23 contacts the card block 26. At this time, the ball screw 24 is driven to rotate through the card connection between the card block 26 and the card gear 23, thereby driving the heating plate 25 to move downward, and the positive electrode 32 and the negative electrode 33 are driven to move downward through the heating plate 25 to contact the power plate 34 in series, so that the heating plate 25 is powered on and heated, so that the hygroscopic film 19 is heated and drained, thereby realizing automatic drainage of the hygroscopic film 19, and then there is no need to manually replace the hygroscopic film 19, which effectively prevents the hygroscopic film 19 from having too much water inside and causing the situation that moisture cannot be removed, and keeps the air entering the oxygen generator body 3 dry. The hygroscopic film 19 is made of a material called "MOF-303" and has extremely strong water absorption.

[0020] like Figure 2 As shown, in one embodiment, spring components 3 28 are fixedly installed on both the front and rear sides of the base 1, a spring component 4 29 is fixedly installed on the bottom end of the base 1, a fixing seat 30 is fixedly installed on the bottom end of the spring component 4 29, and a console 31 is fixedly installed on the top end of the fixing seat 30; The working principle and beneficial effects of the above technical solution are as follows: the spring component three 28 absorbs the lateral vibration generated by the oxygen concentrator body 3, and then the spring component four 29 absorbs the vertical vibration generated by the oxygen concentrator body 3, thereby reducing the shaking of the oxygen concentrator body 3 during operation and the collision with the fixing seat 30, further protecting the oxygen concentrator body 3 and reducing the noise.

[0021] like Figure 3 As shown, in one embodiment, the fixing rod 16 is fixedly connected to the fixing seat 30, the knocking rod 8 is a conical protruding round rod, and the knocking rod 8 is located in the middle of the dustproof net 10 away from the spring assembly 9; The working principle and beneficial effects of the above technical solution are as follows: the fixing rod 16 is fixedly connected to the fixing seat 30, so that the rack 14 can remain in place during the movement of the driving gear 7. At this time, the driving gear 7 is meshed with the rack 14, thereby driving the driving gear 7 to rotate, and then driving the knocking rod 8 to rotate. The knocking rod 8 is a conical raised round rod and is located in the middle of the dustproof net 10, so that during the rotation of the knocking rod 8, the raised part of the knocking rod 8 can knock the dustproof net 10, so that the dustproof net 10 can be stably displaced and vibrated, thereby cleaning the dust attached to the surface.

[0022] like Figure 3As shown, in one embodiment, the bottom end of the air inlet pipe 6 is fixedly connected to a dust outlet pipe 11, the bottom end of the dust outlet pipe 11 is fixedly connected to a placement bin 12, a collection box 13 is placed in the inner cavity of the placement bin 12, and the dustproof net 10 is located in the middle of the top opening of the dust outlet pipe 11; The working principle and beneficial effects of the above technical solution are as follows: the dust is shaken off the dust net 10 and enters the inner cavity of the collecting box 13 along the dust outlet pipe 11, and the dust is collected by the collecting box 13. When a lot of dust is collected in the inner cavity of the collecting box 13, the staff will pull the collecting box 13 out of the inner cavity of the placement bin 12 and clean it, and then pass the dust net 10 through the middle part of the top opening of the dust outlet pipe 11, so that the dust dropped by the dust net 10 can all fall into the inner cavity of the dust outlet pipe 11.

[0023] like Figure 3 As shown, in one embodiment, a water collecting pipe 20 is fixedly connected to the bottom end of the air inlet pipe 6, and a drainage pipe 21 is fixedly connected to the bottom end of the water collecting pipe 20. There are two water collecting pipes 20, and the two water collecting pipes 20 are respectively located at the front and rear sides of the moisture absorption frame 17. There are multiple support plates 18, and the multiple support plates 18 are fixedly installed in the inner cavity of the moisture absorption frame 17; The working principle and beneficial effects of the above technical solution are as follows: the water collecting pipe 20 is located on the front and rear sides of the moisture absorption frame 17, so that when the moisture absorption membrane 19 is heated, water can be discharged from the moisture absorption frame 17 to the inner cavity of the water collecting pipe 20, and then the water can be discharged along the water collecting pipe 20 and the drainage pipe 21.

[0024] like Figure 3 As shown, in one embodiment, a ventilation assembly 27 is fixedly installed at the center of the inner cavity of the air inlet pipe 6. The ventilation assembly 27 is composed of a servo motor and a fan blade, and the fan blade is fixedly sleeved on the output shaft of the servo motor; The working principle and beneficial effects of the above technical solution are: the servo motor drives the fan blades to rotate to generate wind force, so that the air can circulate quickly, and the moisture in the air is absorbed by the hygroscopic film 19 to prevent the ventilation component 27 from getting damp, thereby increasing the service life of the ventilation component 27.

[0025] like Figure 2 As shown, in one embodiment, spring assembly 1 9, spring assembly 2 15, spring assembly 3 28, and spring assembly 4 29 are all composed of a damping telescopic rod and a spring, and the damping telescopic rod is located at the center of the spring inner cavity; The working principle and beneficial effects of the above technical solution are as follows: the dustproof net 10 can be vibrated by the spring component 19, so that the dust debris is shaken off to the inner cavity of the collection box 13 for collection, and then the tension of the driving gear 7 by the spring component 2 15 is made so that the driving gear 7 can always be engaged with the rack 14 during the shaking process, so that the driving gear 7 can drive the knocking rod 8 to rotate, and then the base 1 is damped by the spring component 3 28 and the spring component 4 29 to prevent the base 1 from colliding with the fixing seat 30, thereby protecting the oxygen generator body 3, and positioning and guiding are performed by the damping telescopic rod to prevent the spring from shifting during the deformation process.

[0026] Working principle and use process: Start the ventilation component 27 to suck air into the inner cavity of the oxygen generator body 3 through the air inlet valve 4. At this time, the moisture in the air is absorbed by the moisture absorption membrane 19, and the dust in the air is blocked by the dustproof net 10; Then the oxygen generator body 3 starts to produce oxygen. At this time, the oxygen generator body 3 is cushioned by the spring assembly three 28 and the spring assembly four 29, so that the oxygen generator body 3 will not contact and collide with the fixing seat 30. The shaking of the oxygen generator body 3 makes the driving gear 7 start to move relative to the fixing rod 16, and then meshes with the driving gear 7 through the rack 14, thereby driving the driving gear 7 to rotate, and then the driving gear 7 drives the knocking rod 8 to rotate, and the dustproof net 10 is knocked by the protruding part of the knocking rod 8. At this time, the dustproof net 10 can vibrate greatly through the scalability and elasticity of the spring assembly one 9, so that the dust and debris on the surface of the dustproof net 10 enter the inner cavity of the collection box 13 along the dust outlet pipe 11 for storage; When the base 1 shakes, the locking gear 23 moves. When the base 1 drives the locking gear 23 to shake to a large extent so that the locking gear 23 contacts and engages with the locking block 26, the locking block 26 and the locking gear 23 are engaged, so that the locking gear 23 rotates, thereby driving the ball screw 24 to rotate, so that the heating plate 25 moves along the axial direction of the ball screw 24, and then the positive electrode 32 and the negative electrode 33 contact the power-carrying plate 34, so that the heating plate 25 is energized to heat the hygroscopic film 19 through the support plate 18, so that the heating plate 25 is heated, and the hygroscopic film 19 is heated and drained, so that the water is discharged along the water collecting pipe 20 and the drainage pipe 21.
