Description

Technical Field

[0001] This invention relates to the field of medical oxygen concentrator technology, and more specifically, to a multifunctional medical oxygen concentrator. Background Technology

[0002] Medical oxygen concentrators, by supplying oxygen to patients, can be used in conjunction with the treatment of cardiovascular and cerebrovascular diseases, respiratory diseases, chronic obstructive pulmonary disease, and the rehabilitation of hypoxic conditions. By inhaling oxygen, the body's oxygen supply can be improved, achieving the purpose of nourishment and health care. They are suitable for middle-aged and elderly people, those with poor physical condition, pregnant women, and high school students who have varying degrees of physiological hypoxia. They can also eliminate fatigue and restore bodily functions after heavy physical or mental exertion. For example, a medical oxygen concentrator is disclosed in Chinese patent CN113880052A.

[0003] Medical oxygen concentrators first draw in air from the surrounding environment through the air inlet. As the air enters the concentrator, it passes through an air filter. This filter removes impurities such as dust, pollen, and fibers, acting like a sieve to allow only clean air to proceed to the next stage of processing. The filtered air is then compressed and sent to the compressor, a key component of the oxygen concentrator. Its function is to compress the air and increase its pressure. The compressed air then enters the adsorption tower, which contains molecular sieves. Molecular sieves have different adsorption capacities for different gases. In this stage, the molecular sieves preferentially adsorb impurities such as nitrogen and carbon dioxide from the air, allowing oxygen to pass through. Thus, high-purity oxygen is obtained from the outlet of the adsorption tower.

[0004] In this system, molecular sieves fill the inner cavity of the adsorption tower, adsorbing impurities such as nitrogen from the air entering the cavity. During long-term continuous adsorption, the adsorption sites of the molecular sieves are gradually occupied by nitrogen molecules. When all adsorption sites are occupied, the molecular sieves reach adsorption saturation and can no longer adsorb nitrogen. At this point, the molecular sieves need to be removed from the adsorption tower. However, when replacing the molecular sieves in existing medical oxygen concentrators, the molecular sieves are prone to clumping and adhering to the inner cavity of the adsorption tower due to the influence of moisture in the air. Furthermore, the inner cavity of the adsorption tower is relatively deep, making it inconvenient to disturb and remove the molecular sieves accumulated at the bottom. This results in the time-consuming and laborious process of removing the molecular sieves by tilting them. Therefore, we propose a medical oxygen concentrator that facilitates the replacement of molecular sieves. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional medical oxygen generator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a multifunctional medical oxygen concentrator, comprising a drive base, a compressor fixedly connected to the inner cavity of the drive base, a filter fixedly connected to the bottom of the compressor, a base fixedly connected to the bottom of the compressor, and an adsorption oxygen generation component disposed on the top of the drive base. The adsorption oxygen generation component has a molecular sieve inside its cavity for receiving air from the compressor and separating the air to generate oxygen.

[0007] The adsorption oxygen generation component is provided with a discharge component in its inner cavity. The discharge component is used to guide the molecular sieve downward in an inverted "V" shape to discharge the molecular sieve when it fails and needs to be replaced.

[0008] Furthermore, a cleaning component is provided on the top of the discharge component. The cleaning component is used to generate a pulling force when the discharge component switches from a parallel state to an inverted "V" state, driving it to adhere to the inner wall of the adsorption oxygen generation component and scrape downwards, disturbing the molecular sieve to fall off.

[0009] As a further improvement to this technical solution, the adsorption oxygen generation component includes an adsorption tower fixedly connected to the top of the drive base. An air inlet distributor is fixedly connected to the bottom of the adsorption tower. The air inlet distributor typically adopts a porous structure to distribute the gas evenly. The end of the air inlet distributor away from the adsorption tower is fixedly connected to the compressor. An oxygen exhaust pipe is snapped into the top of the adsorption tower.

[0010] As a further improvement to this technical solution, the discharge assembly includes two support grids rotatably connected to the inner wall of the adsorption tower. The support grids are located above the air inlet distributor, and a container for accommodating the molecular sieve is formed between the support grids and the adsorption tower.

[0011] During oxygen production, two supporting grids are parallel to support the molecular sieve. When replacing the grids, the supporting grids are tilted to guide the molecular sieve.

[0012] As a further improvement to this technical solution, a movable groove is provided at the end of the supporting grid, a spring is fixedly connected to the inner wall of the movable groove, and a movable plate is fixedly connected to the end of the spring away from the spring.

[0013] One end of the movable plate slides on the inner wall of the movable groove, while the other end extends out of the movable groove.

[0014] As a further improvement to this technical solution, four limiting plates are fixedly connected to the inner cavity of the adsorption tower. Limiting grooves are formed on the inner wall of the limiting plates. Rollers are rotatably connected to both ends of the movable plate. The rollers are adapted to roll on the inner wall of the limiting grooves.

[0015] As a further improvement to this technical solution, a groove is formed on the surface of the limiting plate, a baffle is slidably connected to the inner wall of the groove, and a tension spring is fixedly connected to the bottom of the baffle. The end of the tension spring away from the baffle is fixedly connected to the inner wall of the groove, wherein:

[0016] The adsorption tower has two discharge slots on its surface, and the baffle slides on the inner wall of the discharge slot in a sealed manner. Under the action of the spring rebound force, the baffle blocks the communication between the outside and the inside of the adsorption tower. When the moving plate is tilted along with the supporting grid, it squeezes the baffle to move downward, so that the outside and the inside of the adsorption tower can communicate.

[0017] As a further improvement to this technical solution, the cleaning component includes a movable section fixedly connected to the surface of the support grid. A support rod is rotatably connected to the inner wall of the movable section. Multiple crossbars are fixedly connected to the surface of the support rod. Scrapers are fixedly connected to both ends of the crossbars. The outer wall of the scraper fits snugly against the inner wall of the adsorption tower.

[0018] As a further improvement to this technical solution, the rotating shafts at the ends of the two supporting grids both extend out of the inner wall of the adsorption tower and are fixedly connected with gears. The outer walls of the two gears are meshed together, and the end of one of the gears is fixedly connected to the output shaft of a motor.

[0019] As a further improvement to this technical solution, a support frame is fixedly connected to the outer wall of the adsorption tower, and the housing of the motor is fixedly connected to the top of the support frame.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In this multifunctional medical oxygen concentrator, the operation of the motor will drive two gears to rotate in opposite directions. The rotation of the gears will cause the support grid to rotate, and the two support grids will then present an inverted "V" shape.

[0022] The rotation of the supporting grid will drive the moving plate to rotate. During the rotation of the supporting grid, the bottom of the moving plate will contact the top of the baffle, causing the baffle to be misaligned with the discharge chute. As a result, the molecular sieves originally laid flat on the surface of the supporting grid at points s1 and s3 will start to roll to one end due to the tilt of the supporting grid, and finally gather at the lowest points a1 and a2 at one end of the supporting grid. The molecular sieves gathered at the lowest point at one end of the supporting grid will then flow out of the discharge chute. The whole process does not require manual intervention and is easy to operate.

[0023] 2. In this multifunctional medical oxygen generator, the characteristics of the spring ensure that the moving plate remains in contact with the inner wall of the adsorption tower as the supporting grid rotates. This prevents the moving plate from failing to adhere to the inner wall of the adsorption tower due to its length, thus preventing the molecular sieve from detaching from the surface of the supporting grid and the moving plate.

[0024] 3. In this multifunctional medical oxygen generator, the rotation of the support grid will drive the movable section to move. At this time, the movable section will be rotatably connected to the support rod, and the support rod will drive multiple crossbars to move downward. The scraper connected to the surface of the crossbar will move on the inner wall of the adsorption tower. While the crossbar moves downward, it can disperse the molecular sieves that are in contact with it, so that they are restored to a relatively loose state and prevent the molecular sieves from getting stuck in the inner cavity of the adsorption tower.

[0025] The combination of multiple crossbars and scrapers ensures that the cleaning range covers the entire circumference of the inner wall of the adsorption tower. The scrapers are in close contact with the inner wall of the adsorption tower and can effectively scrape off the adhering molecular sieves as they move downwards, ensuring thorough cleaning, reducing residues, and avoiding the impact of residual molecular sieves on subsequent oxygen production.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] Please see Figures 1-12 As shown, this embodiment provides a multifunctional medical oxygen concentrator, including a drive base 100, a compressor 110 fixedly connected to the inner cavity of the drive base 100, a filter element 120 fixedly connected to the bottom of the compressor 110, a base 130 fixedly connected to the bottom of the compressor 110, and an adsorption oxygen generation component 200 disposed on the top of the drive base 100. The adsorption oxygen generation component 200 has a molecular sieve inside its cavity for receiving air from the compressor 110 and separating the air to generate oxygen.

[0048] The adsorption oxygen generation component 200 is provided with a discharge component 300 in its inner cavity. The discharge component 300 is used to form an inverted "V" shape downwards to guide and discharge the molecular sieve when it fails and needs to be replaced.

[0049] Furthermore, a cleaning component 400 is provided on the top of the discharge component 300. The cleaning component 400 is used to generate a pulling force when the discharge component 300 switches from a parallel state to an inverted "V" state, driving it to adhere to the inner wall of the adsorption oxygen generation component 200 and scrape downwards, disturbing the molecular sieve to fall off.

[0050] Outside air first enters the drive base 100 and passes through a filter 120 fixedly connected to the bottom of the compressor 110. The filter 120 removes dust and impurities from the air, ensuring the air entering subsequent stages is clean. Then, the compressor 110 starts and compresses the filtered air. Through mechanical movement, the compressor 110 compresses air molecules into a smaller space, increasing air pressure and providing sufficient energy for subsequent gas separation. The base 130 supports and stabilizes the compressor 110, ensuring it does not shift or shake during operation. The compressed air is then transferred upwards from the compressor 110 to the adsorption oxygen generation component 200 at the top of the drive base 100. The adsorption oxygen generation component 200 is filled with molecular sieves for oxygen separation. The molecular sieves have uniform and specific pore sizes; for example, a common 5A molecular sieve has a pore size of approximately 5 angstroms. The diameter of an oxygen molecule in the air is approximately 3.46 angstroms, nitrogen molecules are approximately 3.64 angstroms, and argon molecules are approximately 3.8 angstroms. Oxygen molecules are allowed to enter the internal channels, while larger molecules such as nitrogen and argon are blocked. Furthermore, the pore size of the 5A molecular sieve is not absolutely rigidly fixed at 5 angstroms; it undergoes a certain degree of elastic deformation when interacting with gas molecules. When oxygen molecules approach, the slight deformation of the molecular sieve pore size allows for better entry. However, for nitrogen and argon molecules, whose diameters are closer to or exceed the adjustable range of the molecular sieve pore size, the elastic deformation makes it difficult for them to pass through smoothly. The channels of the 5A molecular sieve are not simple straight cylinders but have complex shapes and high tortuosity. This complex channel structure, while presenting some resistance to smaller oxygen molecules, allows them to pass through the channels due to their smaller size and better flexibility. Nitrogen and argon molecules, due to their larger diameters, may have difficulty entering the channels at the entrance due to steric hindrance. Even if a very small number of molecules manage to enter, they are easily stuck at bends or narrow sections of the channels and cannot pass through smoothly.

[0051] Considering that during the long-term continuous adsorption process, the adsorption sites of the molecular sieve will gradually be occupied by nitrogen molecules, and when all adsorption sites are filled, the molecular sieve reaches adsorption saturation and can no longer adsorb nitrogen and other impurity gases. At this point, the molecular sieve needs to be removed from the adsorption tower. Existing devices require separating the adsorption tower from the compressor and disassembling the adsorption tower to remove the molecular sieve. Therefore, by setting up the discharge component 300, the molecular sieve can be discharged from the inner cavity of the adsorption oxygen generation component 200 without disassembling it, so that a new molecular sieve can be replaced later. This avoids these unnecessary disassemblies and reduces the risk of equipment damage due to improper human operation.

[0052] Considering the presence of moisture in the air, when the compressor 110 is operating, the air is compressed and transported, and moisture enters the inner cavity of the adsorption oxygen generator 200, directly contacting the molecular sieves that fill it. During long-term continuous gas transport, moisture accumulates, gradually causing the molecular sieves to soften. The softened molecular sieves are prone to deformation and thus adhere to the inner wall of the adsorption oxygen generator 200. When the molecular sieves are expelled from the inner cavity of the adsorption oxygen generator 200, they remain on the inner wall due to adhesion, making complete removal impossible. The residual molecular sieves will not only affect the oxygen production effect after the new molecular sieves are filled, but may also breed bacteria and block gas channels due to long-term accumulation. Therefore, by setting a cleaning component 400 on the surface of the discharge component 300, the cleaning component 400 can scrape off the molecular sieves adhering to the inner wall of the adsorption oxygen generating component 200 when the discharge component 300 discharges the molecular sieves from the inner cavity of the adsorption oxygen generating component 200, ensuring that the molecular sieves can be discharged from the inner cavity of the adsorption oxygen generating component 200 and greatly reducing the residual molecular sieves.

[0053] Based on the above, the specific structure will be disclosed in detail:

[0054] like Figure 2 , 11 As shown, in order for the adsorption oxygen generating component 200 to receive the gas compressed by the compressor 110, the adsorption oxygen generating component 200 includes an adsorption tower 210 fixedly connected to the top of the drive base 100. An air inlet distributor 2102 is fixedly connected to the bottom of the adsorption tower 210. The air inlet distributor 2102 usually adopts a porous structure to distribute the gas evenly. The end of the air inlet distributor 2102 away from the adsorption tower 210 is fixedly connected to the compressor 110. An oxygen exhaust pipe 230 is snapped and connected to the top of the adsorption tower 210. The compressed air is transmitted to the inner cavity of the adsorption tower 210 through the air inlet distributor 2102 by the operation of the compressor 110. At this time, the molecular sieve filling the inner cavity of the adsorption tower 210 will adsorb nitrogen and other impurity gases in the air. Oxygen molecules, due to their own characteristics, are not easily adsorbed by the molecular sieve and can pass through the molecular sieve smoothly. The high-purity oxygen after being adsorbed and purified by the molecular sieve is finally discharged from the oxygen exhaust pipe 230 for subsequent medical oxygen supply.

[0055] Considering that the air entering the adsorption tower 210 cavity through the air inlet distributor 2102 may directly contact the molecular sieve, the molecular sieve near the air inlet distributor 2102 may over-adsorb due to the direct impact of the airflow, while the molecular sieve far from the air inlet may not fully exert its adsorption effect. Therefore, it is necessary to prevent the molecular sieve from directly contacting the air inlet of the air inlet distributor 2102. Further disclosure of the parts of the discharge assembly 300 is required. Therefore, the discharge assembly 300 includes two support grids 310 rotatably connected to the inner wall of the adsorption tower 210. The support grids 310 are located above the air inlet distributor 2102, and a container for accommodating the molecular sieve is formed between the support grids 310 and the adsorption tower 210.

[0056] During oxygen production, two supporting grids 310 support the molecular sieve in a parallel state. When replacing the molecular sieve, the supporting grids 310 tilt to guide the molecular sieve. By setting the supporting grids 310 inside the adsorption tower 210, the oxygen exhaust pipe 230 is manually moved to separate it from the adsorption tower 210, and the molecular sieve is poured into the adsorption tower 210. The molecular sieve poured into the adsorption tower 210 will fall onto the surfaces s1 and s3 of the supporting grids 310. The continuous pouring of molecular sieve will continuously fill the s2 and s4. After the molecular sieve is filled, the oxygen exhaust pipe 230 needs to be fixed back to the inner wall of the adsorption tower 210. The compressed gas is transmitted to the adsorption tower 210 in a uniform manner through the air inlet distributor 2102 by the operation of the compressor 110. When the molecular sieve needs to be replaced, the two supporting grids 310 rotate in opposite directions, presenting an inverted "V" shape, so that the molecular sieve on the surface can move from s1 and s3 to a1 and a2.

[0057] In order to prevent the molecular sieve on the surface of the two support grids 310 from falling off due to the rotation of the support grids 310 during the opposite movement of the two support grids 310, a moving groove 3101 is provided at the end of the support grids 310. A spring 3102 is fixedly connected to the inner wall of the moving groove 3101, and a moving plate 330 is fixedly connected to the end of the spring 3102 away from the spring 3102.

[0058] One end of the movable plate 330 slides on the inner wall of the movable trough 3101, and the other end extends out of the movable trough 3101. When the molecular sieve needs to be discharged, the support grid 310 starts to rotate. During the rotation of the support grid 310, since it is connected to the movable plate 330 by the spring 3102, the elasticity of the spring 3102 will cause the spring 3102 to apply elastic force to the movable plate 330, so that the movable plate 330 always keeps in contact with the inner wall of the adsorption tower 210. As the support grid 310 continues to rotate, the movable plate 330 will slide along the inner wall of the adsorption tower 210, so that the movable plate 330 always adheres to the inner wall of the adsorption tower 210, preventing the molecular sieve from falling off.

[0059] To ensure that the spring 3102 can always push the end of the moving plate 330 against the inner wall of the adsorption tower 210, and to keep the supporting grid 310 stable during transmission, four limiting plates 340 are fixedly connected to the inner cavity of the adsorption tower 210. Limiting grooves 3401 are formed in the inner wall of the limiting plates 340. Rollers 3301 are rotatably connected to both ends of the moving plate 330. The rollers 3301 are adapted to roll along the inner wall of the limiting grooves 3401. As the supporting grid 310 rotates... This will cause the movable plate 330 to rotate. At this time, the roller 3301 will move on the inner wall of the limiting groove 3401, and the spring 3102 can compensate for the distance required by the movable plate 330 during rotation, making the rotation of the movable plate 330 more stable. At the same time, the roller 3301 will slide on the inner wall of the limiting groove 3401, so that the position stretched by the spring 3102 can be limited by the roller 3301, so that the end of the movable plate 330 can always be in contact with the inner wall of the adsorption tower 210.

[0060] Considering that the molecular sieves on the surface of the two supporting grids 310 can be flattened by rotating in opposite directions, and that the molecular sieves need to be able to be discharged from the inner cavity of the adsorption tower 210 when they roll from s1 and s3 to a1 and a2, a groove 3402 is provided on the surface of the limiting plate 340. A baffle 350 is slidably connected to the inner wall of the groove 3402, and a tension spring 3501 is fixedly connected to the bottom of the baffle 350. The end of the tension spring 3501 away from the baffle 350 is fixedly connected to the inner wall of the groove 3402, wherein:

[0061] Two discharge slots 2101 are provided on the surface of the adsorption tower 210, and the baffle 350 slides on the inner wall of the discharge slot 2101 in a sealing manner. Under the action of the spring 3501, the baffle 350 blocks the communication between the outside and the inside of the adsorption tower 210. When the moving plate 330 is tilted with the support grid 310, it squeezes the baffle 350 downward, allowing the outside to communicate with the inside of the adsorption tower 210. In the initial state, the spring 3501 is in the extended state, and its elastic force pushes the baffle 350, so that the baffle 350 is tightly pressed against the surface of the discharge slot 2101 to prevent outside air from entering the inner cavity of the adsorption tower 210, ensuring that the working environment and gas state inside the adsorption tower are not disturbed by outside air. When it is necessary to discharge the molecular sieve, the moving plate 330 rotates. During the rotation, due to the elastic force of the spring 3102 and the rolling of the roller 3301 in the limiting groove, the molecular sieve is discharged. Due to the limiting effect, the moving plate 330 will move downward. As the moving plate 330 gradually moves downward, the bottom of the moving plate 330 will contact the top of the baffle 350. If the moving plate 330 continues to rotate, it will apply downward pressure to the baffle 350. Under the action of this pressure, the baffle 350 will move downward. At this time, the tension spring 3501 will be compressed by the pressure. As the baffle 350 moves downward, the baffle 350 will be misaligned with the position of the discharge chute 2101, thereby opening the opening of the discharge chute 2101. When the opening of the discharge chute 2101 is opened, the molecular sieves originally laid flat on the surface of the support grid 310 at s1 and s3 will begin to roll or slide to one end due to the tilt of the support grid 310, and finally gather at the lowest a1 and a2 at one end of the support grid 310, and flow out smoothly from the opening of the discharge chute 2101, realizing the discharge operation of the molecular sieve from the inner cavity of the adsorption tower 210.

[0062] In order for the cleaning assembly 400 to discharge the molecular sieve from the inner cavity of the adsorption tower 210 along with the discharge assembly 300, and to scrape off the molecular sieve adhering to the inner wall of the adsorption tower 210, it is necessary to further disclose the parts of the cleaning assembly 400. Therefore, the cleaning assembly 400 includes a movable section 410 fixedly connected to the surface of the support grid 310. A support rod 420 is rotatably connected to the inner wall of the movable section 410. A plurality of crossbars 4201 are fixedly connected to the surface of the support rod 420. Scrapers 430 are fixedly connected to both ends of the crossbars 4201. The wall is fitted to the inner wall of the adsorption tower 210. The rotation of the support grid 310 can drive the movable section 410 to move accordingly. At this time, the movable section 410 will be rotatably connected to the support rod 420, causing the support rod 420 to move downward. Then, the downward movement of the support rod 420 will drive the crossbar 4201 to move downward. Due to the downward movement of the crossbar 4201, the scraper 430 will move downward. Since the surface of the scraper 430 is in contact with the inner wall of the adsorption tower 210, the scraper 430 will cause the molecular sieves adhering to the surface of the adsorption tower 210 to fall off.

[0063] In order to enable the support grid 310 to rotate, the shafts at the ends of both support grids 310 are rotated to extend out of the inner wall of the adsorption tower 210 and are fixedly connected to gears 320. The outer walls of the two gears 320 are meshed together, and the end of one gear 320 is fixedly connected to the output shaft of the motor 3201. The operation of the motor 3201 can make the two gears 320 rotate in opposite directions. The opposite rotation of the two gears 320 can drive the two support grids 310 to rotate into an inverted "V" shape.

[0064] In order for the motor 3201 to drive the gear 320 to rotate, the motor 3201 needs to be supported and fixed. Therefore, a support frame 220 is fixedly connected to the outer wall of the adsorption tower 210, and the outer shell of the motor 3201 is fixedly connected to the top of the support frame 220. By setting the support frame 220 on the surface of the adsorption tower 210, the support frame 220 supports and fixes the motor 3201.

[0065] In summary, the workflow of this invention is as follows:

[0066] exist Figure 3-7 as well as Figure 11 The image shows the workflow where compressor 110 delivers air to the inner cavity of adsorption tower 210, and the molecular sieve inside adsorption tower 210 separates oxygen from the incoming air:

[0067] Outside air first enters the drive base 100 and passes through the filter 120 fixedly connected to the bottom of the compressor 110. The filter 120 filters out dust, impurities, and other contaminants from the air, ensuring the air entering subsequent stages is clean. Then, the compressor 110 starts and compresses the filtered air. Through mechanical movement, the compressor 110 compresses air molecules into a smaller space, increasing air pressure. The operation of the compressor 110 causes the compressed gas to be evenly distributed to the inner cavity of the adsorption tower 210 via the air inlet distributor 2102. At this point, the gas initially positioned below the support grid 310 is... Figure 11 Subsequently, driven by the pressure difference, the gas gradually passes through the pores of the supporting grid 310. Figure 11 The airflow indicated by the arrow flows upward and comes into full contact with the molecular sieve above, activating the adsorption stage in the oxygen generation process. The high-purity oxygen, after being adsorbed and purified by the molecular sieve, is finally discharged from the oxygen exhaust pipe 230 for subsequent medical oxygen supply.

[0068] exist Figure 8 , Figure 9 , Figure 10 as well as Figure 12 The process of discharging the molecular sieve from the adsorption tower 210 by the discharge component 300 is as follows:

[0069] When the molecular sieve needs to be discharged, the two support grids 310 rotate in opposite directions, causing them to form a herringbone shape, such as... Figure 12 The rotation of the support grid 310 causes the movable plate 330 to rotate accordingly. At this time, the roller 3301 moves along the inner wall of the limiting groove 3401, and the spring 3102 is stretched. The stretching of the spring 3102 compensates for the distance required by the movable plate 330 during rotation, ensuring that the movable plate 330 always presses against the inner wall of the adsorption tower 210. When the support grid 310 rotates to a certain angle, reaching the position of the discharge chute 2101, the bottom of the movable plate 330 contacts the top of the baffle 350. Continuing to rotate the movable plate 330 applies downward pressure to the baffle 350. Under this pressure, the baffle 350 moves downward. At this time, the tension spring 3501 contracts under pressure. As the baffle 350 moves downward, it shifts away from the position of the discharge chute 2101, thus opening the opening of the discharge chute 2101. At this time, the support grid 310 will exhibit a certain tilt. Figure 12 The molecular sieves at points s1 and s3, originally laid flat on the surface of the support grid 310 as indicated by the arrow, will begin to roll or slide towards one end due to the tilt of the support grid 310, eventually accumulating at the lowest points a1 and a2 at one end of the support grid 310. At this point, since the support grid 310 has rotated to the discharge chute 2101, the adsorption tower 210 at the corresponding position will no longer obstruct the molecular sieves because the baffle 350 will be offset from the position of the discharge chute 2101. Under the action of gravity, the molecular sieves accumulated at the lowest point at one end of the support grid 310 will flow out from the discharge chute 2101. Figure 12 The point indicated by the arrow.
