Abstract

This invention discloses a medical oxygen concentrator with oxygen-enriched nebulization function, belonging to the field of medical oxygen concentrator technology. It includes a casing, nebulizer, filter, compressor, condenser, molecular sieve assembly, gas storage chamber, and humidifier bottle. The invention utilizes a second electric telescopic rod to drive the reciprocating motion of the pressing assembly, which, in conjunction with a vibrating block, causes the bottom support ring to move up and down at varying speeds. This impact causes vibration in the outer shell of the tank. The variable-speed up-and-down movement of the bottom support ring causes the failed molecular sieve particles on it to fall more violently.

Description

Technical Field

[0001] This invention relates to the field of medical oxygen generator technology, specifically a medical oxygen generator with oxygen-enriched nebulization function. Background Technology

[0002] Oxygen-enriched nebulizers are indispensable equipment in modern medical systems, playing a significant role in improving patients' quality of life, assisting in disease treatment, and ensuring life safety. Medical oxygen concentrators utilize advanced physical or chemical technologies to efficiently separate high concentrations of oxygen from the air, providing patients with a stable and continuous oxygen supply. By inhaling high-concentration oxygen, patients can significantly improve their hypoxic state, alleviate symptoms such as difficulty breathing, and thus improve their quality of life. Oxygen-enriched nebulizers, in particular, add a nebulization function to an oxygen concentrator, combining pure oxygen with nebulized medication for specific treatments.

[0003] The core component of an oxygen concentrator is a molecular sieve. Molecular sieves are prone to moisture damage and failure. A failed molecular sieve cannot effectively separate oxygen, so it needs to be replaced after it fails. Currently, replacing a molecular sieve requires a professional to disassemble the molecular sieve tank and refill it with molecular sieve particles. This method is cumbersome and difficult for users to do themselves. Summary of the Invention

[0004] The purpose of this invention is to provide a medical oxygen generator with oxygen-enriched nebulization function to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a medical oxygen generator with oxygen-enriched nebulization function, comprising a casing, on which an nebulizer and a humidifier are installed. Inside the casing are a filter, a compressor, a condenser, and a gas storage chamber. Two sets of molecular sieve components are installed inside the casing. The filter is connected to the compressor via a pipe, the compressor is connected to the condenser via a pipe, the condenser is connected to the molecular sieve components via a pipe, the molecular sieve components are connected to the gas storage chamber via a pipe, and the gas storage chamber is connected to the nebulizer and the humidifier via pipes respectively. The molecular sieve components include a waste bin and a feeding hopper. A support is symmetrically installed on the waste bin, and a tank assembly is installed on the support. A telescopic hose is installed at the bottom of the tank assembly, one end of which is connected to the waste bin. A first electric valve is symmetrically installed on the feeding hopper, and a discharge pipe is installed on the first electric valve. The discharge pipe is connected to the tank assembly. The bottom of the tank assembly is connected to the condenser via a pipe, and the top of the tank assembly is connected to the gas storage chamber via a pipe.

[0006] The machine is equipped with a control system, which is used to control the entire medical oxygen generator.

[0007] The control system turns on the oxygen generator. The filter first filters the air, and the filtered air is compressed by the compressor and then enters the condenser for cooling. The air then enters the molecular sieve assembly from the condenser. The molecular sieve assembly blocks nitrogen in the air and allows oxygen to pass through. The two sets of molecular sieve assemblies operate alternately, and the separated oxygen enters the gas storage chamber. The control system delivers the oxygen from the gas storage chamber to the humidifier or nebulizer as needed. The nebulizer uses oxygen to atomize the medicine, achieving the function of oxygen-enriched atomization, while the humidifier directly humidifies the oxygen, achieving the function of pure oxygen delivery.

[0008] Furthermore, the tank assembly includes a tank shell, which is mounted on a bracket. An upper pressure assembly is slidably mounted on the top of the tank shell, and a lower pressure assembly is mounted on the bottom of the tank shell. A feeding assembly is mounted on the tank shell and is connected to a discharge pipe. The tank shell is provided with a corrugated groove, and the lower pressure assembly is fitted into the corrugated groove. The lower pressure assembly is connected to the condenser through a pipe and is connected to a telescopic hose. The upper pressure assembly is slidably connected to the feeding assembly and is connected to the gas storage chamber through a pipe.

[0009] The outer shell of the tank is filled with molecular sieve particles, which are used to separate oxygen.

[0010] Furthermore, a motor bracket is mounted on the pressing component, an adjusting motor is mounted on the motor bracket, and an adjusting gear is mounted on the output shaft of the adjusting motor. The adjusting gear meshes with the pressing component for transmission.

[0011] During oxygen production, the control system puts the tank assembly into oxygen production mode. Air cooled by the condenser enters the air intake channel through the air intake pipe, then passes through the first filter screen into the outer shell of the tank. The air passes through molecular sieve particles, and oxygen flows out from the upper outlet pipe and enters the gas storage chamber. The two sets of tank assemblies operate alternately to achieve the effect of oxygen production.

[0012] When shut down, the control system puts the tank assembly into a moisture-proof mode, sealing both the top and bottom of the tank shell to isolate the molecular sieve particles from the air. This prevents the molecular sieve particles from absorbing moisture from the air and becoming ineffective when the oxygen generator is not used for a long time, thus achieving a moisture-proof effect.

[0013] Furthermore, the feeding assembly includes a feeding housing and a sliding block. A sliding rod is mounted on the sliding block and is slidably mounted on the feeding housing. A feeding spring is installed between the sliding block and the feeding housing. The feeding housing is provided with a feeding hole and is connected to the discharge pipe through the feeding hole. The feeding housing is slidably connected to the upper pressure assembly, and the sliding block is slidably connected to the upper pressure assembly.

[0014] Furthermore, the upper pressure assembly includes a first electric telescopic rod, which is installed on the outer shell of the tank. The output shaft of the first electric telescopic rod passes through the outer shell of the tank and is mounted on an upper tray. An upper sliding rod is slidably mounted on the upper tray. An upper pressure plate is mounted at the bottom end of the upper sliding rod. An upper pressure spring is installed between the upper pressure plate and the upper tray. A discharge cylinder is slidably mounted on the upper tray. The discharge cylinder is slidably connected to the infeed outer shell. A discharge spring is installed between the discharge cylinder and the upper tray. The discharge cylinder is slidably connected to a sliding block. The discharge cylinder is slidably connected to the upper pressure plate. The upper pressure plate is slidably connected to the outer shell of the tank.

[0015] The control system drives the upper pressure assembly to slide up and down inside the tank shell via the first electric telescopic rod. When the oxygen generator is producing oxygen, the first electric telescopic rod prevents the vertical cylinder on the upper pressure assembly from contacting the sliding block, and the tank assembly enters the oxygen production mode. At this time, under the action of the feeding spring, the bottom plate and the upper pressure plate are tightly fitted together, and the second electric valve on the outlet pipe is opened, allowing the separated oxygen to flow out from the outlet pipe. When the oxygen generator is turned off, the second electric valve on the outlet pipe is closed, preventing external gas from entering the tank shell through the outlet pipe. The first electric valve is also closed, preventing external air from entering the tank shell through the feed hole. The two sliding blocks are tightly fitted together under the action of the feeding spring, isolating the air. The tank assembly enters the moisture-proof mode, achieving the purpose of isolating the air and preventing the molecular sieve particles from becoming damp and failing.

[0016] When the molecular sieve particles become ineffective due to prolonged use or moisture, the first electric telescopic rod drives the upper pressure assembly to retract, and the upper tray moves the vertical cylinder upward. The inclined surface on the vertical cylinder squeezes the sliding blocks. After being squeezed, the two sliding blocks slide horizontally and move away from each other until the vertical cylinder passes through. When the limiting plate on the vertical cylinder contacts the top of the tank shell, the vertical cylinder is limited and cannot move upward. At this time, the upper tray overcomes the spring force of the feeding spring and moves upward relative to the vertical cylinder. The upper sliding rod and the upper pressure plate on the upper tray move upward relative to the vertical cylinder along with the upper tray. The relative displacement between the upper pressure plate and the vertical cylinder causes the bottom plate of the vertical cylinder to disengage from the upper pressure plate and allow the discharge hole to pass through the upper pressure plate. The tank assembly enters the replacement mode. When new molecular sieve particles enter from the feed hole, they fall from the feed shell into the vertical cylinder and then from the discharge hole at the bottom of the vertical cylinder into the tank shell, achieving the material replacement effect.

[0017] Furthermore, the feeding cylinder includes a vertical cylinder, which is slidably connected to the feeding shell. The vertical cylinder has a sloping surface and a limit plate is installed on it. A feeding spring is installed between the limit plate and the upper pallet. The vertical cylinder is slidably connected to the upper pallet and the upper pressure plate. The bottom end of the vertical cylinder has a discharge hole and a base plate is installed at the bottom end. An air outlet pipe is installed on the base plate. The bottom end of the air outlet pipe is flush with the bottom end of the base plate. A second filter screen is provided at the bottom end of the air outlet pipe, and a second electric valve is installed inside the air outlet pipe.

[0018] Furthermore, the pressure-down assembly includes a second electric telescopic rod, which is installed at the bottom of the tank shell. A lower tray is mounted on the output shaft of the second electric telescopic rod, and a vibrating base assembly is slidably mounted on the lower tray. A pressure-down spring is installed between the vibrating base assembly and the lower tray. A discharge pipe is rotatably mounted inside the vibrating base assembly and is movably connected to the tank shell. A motor bracket is mounted on the vibrating base assembly, and the discharge pipe meshes with an adjusting gear for transmission. The discharge pipe is connected to the condenser through a pipe, and a telescopic hose is connected to the discharge pipe.

[0019] Furthermore, the vibrating base assembly includes a base ring with a discharge ramp, an adjusting cylinder, and several first discharge ports equidistantly arranged on the adjusting cylinder. Several vibrating blocks are slidably installed inside the base ring, the vibrating blocks are fitted with corrugated grooves, and a vibrating spring is provided between the vibrating blocks and the base ring. Several sliding rods are installed at the bottom end of the base ring and are slidably installed on the lower tray. A motor bracket is installed at the bottom end of the base ring. A discharge pipe is rotatably installed inside the adjusting cylinder. The base ring is slidably connected to the outer shell of the tank, and a downward pressure spring is installed between the base ring and the lower tray.

[0020] When the molecular sieve particles fail and need to be replaced, the control system puts the tank assembly into replacement mode. The control system activates the second electric telescopic rod, and the output shaft of the second electric telescopic rod drives the pressing assembly to move up and down reciprocally. When the vibrating block inside the bottom support ring encounters a protrusion on the corrugated groove, it will be pressed and retract into the bottom support ring. When the vibrating block encounters a depression on the corrugated groove, it will rebound quickly under the action of the vibration spring and slightly impact the outer shell of the tank. The outer shell of the tank will vibrate after being impacted, and the vibrating block will encounter resistance when passing the protrusion. When the resistance is transmitted to the bottom support ring through the vibrating block, it will cause the bottom support ring to decelerate. When the vibrating block passes the depression, the resistance disappears, and the bottom support ring resumes its speed, thereby causing the bottom support ring to move up and down at varying speeds. The variable speed movement of the bottom support ring causes the failed molecular sieve particles on the bottom support ring to fall more violently. The feeding ramp on the bottom support ring causes the molecular sieve particles to converge towards the first discharge port on the regulating cylinder. The vibration of the tank shell, combined with the shaking of the bottom support ring, makes the feeding faster and more efficient. At the same time, it also disperses the agglomerated molecular sieve particles, preventing them from clogging the first discharge port. The molecular sieve particles enter the second discharge port from the first discharge port, and then enter the waste bin from the discharge pipe. The staff will then pull out the waste box and empty the waste, thus realizing the unloading of the failed molecular sieve particles.

[0021] After unloading, the control system aligns the baffle on the unloading pipe with the first unloading port, sealing the first unloading port. Workers pour new molecular sieve particles into the feeding hopper. The control system opens the first electric valve on the side requiring material replacement. The molecular sieve particles fall from the discharge pipe into the feeding shell, then from the vertical cylinder into the tank shell. The control system then activates the second electric telescopic rod. The output shaft of the second electric telescopic rod drives the lowering assembly to move up and down reciprocally. The vibration of the tank shell and the bumping of the bottom support ring compact the new molecular sieve particles, while also dispersing any agglomerates. After the molecular sieve particles are filled, the control system uses the first and second electric telescopic rods to drive the upper and lowering assemblies to press the molecular sieve particles. The upper pressure plate presses the molecular sieve particles and overcomes the upper pressure spring force to retract the upper sliding rod. The bottom support ring presses the molecular sieve particles and overcomes the lower pressure spring force to retract the lower sliding rod. Finally, the control system puts the tank assembly into a moisture-proof mode, thus completing the unloading and material replacement of the entire molecular sieve assembly waste.

[0022] Furthermore, the unloading pipe fitting includes an unloading pipe, which is installed inside an adjusting cylinder. One end of the unloading pipe is connected to a telescopic hose. An adjusting gear ring is installed on the unloading pipe, and the adjusting gear ring meshes with an adjusting gear for transmission. An air inlet pipe is installed inside the unloading pipe, and several air inlets are installed on the air inlet pipe. The air inlets are connected to the unloading pipe, and one end of the air inlet pipe passes through the unloading pipe and is connected to the condenser through a pipe. One end of the unloading pipe is provided with several second unloading ports, the size and number of which correspond to the size of the first unloading ports. Several first filter screens are provided on the unloading pipe, the position and number of which correspond to the air inlets. A baffle is provided on the unloading pipe, with the baffle located on one side of the first filter screen and the second unloading ports located on the other side of the first filter screen.

[0023] The control system drives an adjusting gear via a motor, which in turn drives the unloading pipe via an adjusting gear ring. When the oxygen generator is producing oxygen, the control system positions the first filter screen on the unloading pipe at the center of the first unloading port, and the tank assembly enters oxygen production mode. At this time, air enters the intake duct through the intake pipe, passes through the first filter screen, and enters the outer shell of the tank. The first filter screen blocks molecular sieve particles but allows air to pass through. When the oxygen generator is turned off, the control system aligns the baffle on the unloading pipe with the first unloading port, and the tank assembly enters moisture-proof mode. At this time, the first unloading port is blocked by the baffle, isolating the air and preventing the molecular sieve particles from contacting the air. When the molecular sieve particles become ineffective due to prolonged use or moisture, the control system aligns the second unloading port on the unloading pipe with the first unloading port, and the tank assembly enters replacement mode. At this time, the ineffective molecular sieve particles can pass through both the first and second unloading ports, falling through the gap between the intake pipe and the unloading pipe.

[0024] Furthermore, a waste drawer is slidably installed on the waste bin.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. In oxygen production mode, air enters through the inlet and flows into the storage chamber through the outlet. The two sets of tank components operate alternately to achieve oxygen production. In moisture-proof mode, by closing the second and first electric valves, external gas cannot enter the tank shell through either the outlet or the feed port. The two sliding blocks are tightly fitted under the action of the feed spring, isolating the air. The control system aligns the baffle on the discharge pipe with the first discharge port. At this time, the first discharge port is blocked by the baffle, isolating the air and preventing the molecular sieve particles from contacting the air, thus achieving a sealing and moisture-proof purpose.

[0027] 2. The second electric telescopic rod drives the downward pressing component to reciprocate, which, in conjunction with the vibrating block, causes the bottom support ring to move up and down at varying speeds. This impact causes the tank shell to vibrate. The variable-speed up-and-down movement of the bottom support ring causes the failed molecular sieve particles on it to fall more violently. The discharge ramp on the bottom support ring causes the molecular sieve particles to converge towards the first discharge port on the regulating cylinder. The vibration of the tank shell, combined with the shaking of the bottom support ring, makes the discharge faster and more efficient, while also dispersing the agglomerated molecular sieve particles, achieving the purpose of rapid discharge of failed molecular sieve particles and preventing blockage. The vibration of the tank shell and the shaking of the bottom support ring also compact the new molecular sieve particles, while also dispersing the agglomerated molecular sieve particles, achieving the purpose of filling with molecular sieve particles.

[0028] 3. Based on the different modes of the tank components, the unloading pipe is rotated by the adjusting motor, so that the unloading pipe can change different forms in conjunction with the vibrating base assembly; the first electric telescopic rod is used to move the upper pressure assembly to different positions inside the tank shell, so that the upper pressure assembly can switch to different forms according to the different modes of the tank components, thereby achieving the purpose of multi-mode switching of the tank components.

Detailed Implementation

[0040] The technical solutions of 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.

[0041] like Figures 1-10As shown, this invention provides a medical oxygen concentrator with oxygen-enriched nebulization function: It includes a casing 1, on which a nebulizer 2 and a humidifier bottle 8 are installed. Inside the casing 1 are a filter 3, a compressor 4, a condenser 5, and a gas storage chamber 7. Two molecular sieve components 6 are installed inside the casing 1. The filter 3 is connected to the compressor 4 via a pipe, the compressor 4 is connected to the condenser 5 via a pipe, the condenser 5 is connected to the molecular sieve components 6 via a pipe, the molecular sieve components 6 are connected to the gas storage chamber 7 via a pipe, and the gas storage chamber 7 is connected to the nebulizer 2 via pipes. It is connected to the humidifier bottle 8; the molecular sieve assembly 6 includes a waste bin 62 and a feeding hopper 61. A bracket 64 is symmetrically installed on the waste bin 62. A tank assembly 9 is installed on the bracket 64. A telescopic hose 67 is installed at the bottom of the tank assembly 9. One end of the telescopic hose 67 is connected to the waste bin 62. A first electric valve 66 is symmetrically installed on the feeding hopper 61. A discharge pipe 65 is installed on the first electric valve 66. The discharge pipe 65 is connected to the tank assembly 9. The bottom of the tank assembly 9 is connected to the condenser 5 through a pipe. The top of the tank assembly 9 is connected to the gas storage chamber 7 through a pipe.

[0042] The control system is located inside the chassis 1 and is used to control the entire medical oxygen generator.

[0043] The tank assembly 9 includes a tank shell 91, which is mounted on a bracket 64. An upper pressure assembly 93 is slidably mounted on the top of the tank shell 91, and a lower pressure assembly 94 is mounted on the bottom of the tank shell 91. A feeding assembly 92 is mounted on the tank shell 91 and is connected to a discharge pipe 65. The tank shell 91 is provided with a corrugated groove 95, which is fitted into the lower pressure assembly 94. The lower pressure assembly 94 is connected to the condenser 5 through a pipe and is connected to a telescopic hose 67. The upper pressure assembly 93 is slidably connected to the feeding assembly 92 and is connected to the gas storage chamber 7 through a pipe.

[0044] The outer shell 91 of the tank is filled with molecular sieve particles, which are used to separate oxygen.

[0045] A motor bracket 96 is mounted on the pressing assembly 94, an adjusting motor 98 is mounted on the motor bracket 96, an adjusting gear 97 is mounted on the output shaft of the adjusting motor 98, and the adjusting gear 97 meshes with the pressing assembly 94 for transmission.

[0046] The feeding assembly 92 includes a feeding housing 921 and a sliding block 922. A sliding rod 924 is mounted on the sliding block 922 and is slidably mounted on the feeding housing 921. A feeding spring 923 is installed between the sliding block 922 and the feeding housing 921. The feeding housing 921 is provided with a feeding hole 925 and is connected to the discharge pipe 65 through the feeding hole 925. The feeding housing 921 is slidably connected to the upper pressure assembly 93, and the sliding block 922 is slidably connected to the upper pressure assembly 93.

[0047] The upper pressure assembly 93 includes a first electric telescopic rod 931, which is mounted on the outer shell 91 of the tank. The output shaft of the first electric telescopic rod 931 passes through the outer shell 91 of the tank and is mounted on an upper tray 936. An upper sliding rod 937 is slidably mounted on the upper tray 936. An upper pressure plate 932 is mounted at the bottom of the upper sliding rod 937. An upper pressure spring 933 is installed between the upper pressure plate 932 and the upper tray 936. A discharge cylinder 934 is slidably mounted on the upper tray 936. The discharge cylinder 934 is slidably connected to the infeed shell 921. A discharge spring 935 is installed between the discharge cylinder 934 and the upper tray 936. The discharge cylinder 934 is slidably connected to the sliding block 922. The discharge cylinder 934 is slidably connected to the upper pressure plate 932. The upper pressure plate 932 is slidably connected to the outer shell 91 of the tank.

[0048] The control system drives the upper pressure assembly 93 to slide up and down inside the tank shell 91 via the first electric telescopic rod 931. When the oxygen generator is generating oxygen, the first electric telescopic rod 931 prevents the vertical cylinder 9341 on the upper pressure assembly 93 from contacting the sliding block 922, and the tank assembly 9 enters the oxygen generation mode. At this time, under the action of the feeding spring 935, the bottom plate 9344 and the upper pressure plate 932 are tightly fitted together, and the second electric valve on the outlet pipe 9345 is opened, allowing the separated oxygen to flow out from the outlet pipe 9345. When the oxygen generator is turned off, the second electric valve on the outlet pipe 9345 is closed, preventing external gas from entering the tank shell 91 through the outlet pipe 9345. The first electric valve 66 is closed, preventing external air from entering the tank shell 91 through the feed hole 925. The two sliding blocks 922 are tightly fitted together under the action of the feeding spring 923, isolating the air. The tank assembly 9 enters the moisture-proof mode, achieving the purpose of isolating the air and preventing the molecular sieve particles from becoming damp and failing.

[0049] When the molecular sieve particles become ineffective due to prolonged use or moisture, the first electric telescopic rod 931 drives the upper pressure assembly 93 to retract, and the upper tray 936 drives the vertical cylinder 9341 to move upward. The inclined surface 9342 on the vertical cylinder 9341 presses against the sliding block 922. After being pressed, the two sliding blocks 922 slide horizontally and move away from each other until the vertical cylinder 9341 passes through. When the limiting plate 9346 on the vertical cylinder 9341 contacts the top of the tank shell 91, the vertical cylinder 9341 is limited and cannot move upward. At this time, the upper tray 936 overcomes the elastic force of the feeding spring 935 and generates a relative upward displacement with the vertical cylinder 9341. The upper sliding rod 937 and the upper pressure plate 932 on the upper tray 936 move upward relative to the vertical cylinder 9341 together with the upper tray 936. The relative displacement between the upper pressure plate 932 and the vertical cylinder 9341 causes the bottom plate 9344 at the bottom of the vertical cylinder 9341 to disengage from the upper pressure plate 932, and the discharge hole 9343 passes through the upper pressure plate 932. The tank assembly 9 enters the replacement mode. When new molecular sieve particles enter from the feed hole 925, they will fall from the feed shell 921 into the vertical cylinder 9341, and then fall from the discharge hole 9343 at the bottom of the vertical cylinder 9341 into the tank shell 91, achieving the material replacement effect.

[0050] The feeding cylinder 934 includes a vertical cylinder 9341, which is slidably connected to the feeding shell 921. The vertical cylinder 9341 has a ramp surface 9342. A limit plate 9346 is installed on the vertical cylinder 9341. A feeding spring 935 is installed between the limit plate 9346 and the upper tray 936. The vertical cylinder 9341 is slidably connected to the upper tray 936 and to the upper pressure plate 932. The bottom end of the vertical cylinder 9341 has a discharge hole 9343. A base plate 9344 is installed at the bottom end of the vertical cylinder 9341. An air outlet pipe 9345 is installed on the base plate 9344. The bottom end of the air outlet pipe 9345 is flush with the bottom end of the base plate 9344. A second filter screen is provided at the bottom end of the air outlet pipe 9345. A second electric valve is installed inside the air outlet pipe 9345.

[0051] The pressure assembly 94 includes a second electric telescopic rod 941, which is installed at the bottom of the tank shell 91. A lower tray 945 is installed on the output shaft of the second electric telescopic rod 941. A vibration base assembly 942 is slidably installed on the lower tray 945. A pressure spring 943 is installed between the vibration base assembly 942 and the lower tray 945. A discharge pipe 944 is rotatably installed inside the vibration base assembly 942. The discharge pipe 944 is movably connected to the tank shell 91. A motor bracket 96 is installed on the vibration base assembly 942.

[0053] The unloading fitting 944 includes an unloading pipe 9442, which is installed inside an adjusting cylinder 9421. One end of the unloading pipe 9442 is connected to a telescopic hose 67. An adjusting gear ring 9441 is installed on the unloading pipe 9442, and the adjusting gear ring 9441 meshes with the adjusting gear 97. An air inlet pipe 9444 is installed inside the unloading pipe 9442, and several air inlets 9443 are installed on the air inlet pipe 9444. The air inlets 9443 are connected to the unloading pipe 9442, and one end of the air inlet pipe 9444 passes through the unloading pipe. 9442 is connected to the condenser 5 via a pipe. One end of the unloading pipe 9442 is provided with several second unloading ports 9446. The size and number of the second unloading ports 9446 correspond to the size of the first unloading port 9426. Several first filter screens 9445 are provided on the unloading pipe 9442. The position and number of the first filter screens 9445 correspond to the air inlet 9443. A baffle 9447 is provided on the unloading pipe 9442. The baffle 9447 is located on one side of the first filter screen 9445, and the second unloading ports 9446 are located on the other side of the first filter screen 9445.

[0054] The control system drives the adjusting gear 97 to rotate via the adjusting motor 98. The adjusting gear 97, through the adjusting gear ring 9441, drives the unloading pipe 9442 to rotate. When the oxygen generator is producing oxygen, the control system positions the first filter screen 9445 on the unloading pipe 9442 in the middle of the first unloading port 9426, and the tank assembly 9 enters the oxygen production mode. At this time, air enters the air intake duct 9443 from the air intake pipe 9444, and then passes through the first filter screen 9445 from the air intake duct 9443 into the tank shell 91. The first filter screen 9445 is used to block molecular sieve particles and allow air to pass through. When the oxygen generator is turned off, the control system adjusts the unloading pipe 9442... When the baffle 9447 on the tank is aligned with the first discharge port 9426, the tank assembly 9 enters the moisture-proof mode. At this time, the first discharge port 9426 is blocked by the baffle 9447, which isolates the air and prevents the molecular sieve particles from contacting the air. When the molecular sieve particles fail due to prolonged use or moisture, the control system aligns the second discharge port 9446 on the discharge pipe 9442 with the first discharge port 9426, and the tank assembly 9 enters the replacement mode. At this time, the failed molecular sieve particles can pass through the first discharge port 9426 and the second discharge port 9446, and the molecular sieve particles fall from the gap between the air inlet pipe 9444 and the discharge pipe 9442.

[0055] A waste drawer 63 is slidably installed on the waste bin 62.

[0056] The working principle of this invention is as follows: The control system turns on the oxygen generator. The filter 3 first filters the air. The filtered air is compressed by the compressor 4 and then enters the condenser 5 for cooling. The air then enters the molecular sieve assembly 6 from the condenser 5. The molecular sieve assembly 6 blocks the nitrogen in the air and allows the oxygen to pass through. The two sets of molecular sieve assemblies 6 operate alternately. The separated oxygen enters the gas storage chamber 7. The control system delivers the oxygen from the gas storage chamber 7 to the humidifier bottle 8 or the nebulizer 2 as needed. The nebulizer 2 uses oxygen to atomize the medicine, realizing the function of oxygen-enriched atomization. The humidifier bottle 8 directly humidifies the oxygen, realizing the function of pure oxygen delivery.

[0057] During oxygen production, the control system puts the tank assembly 9 into oxygen production mode. The air cooled by the condenser 5 enters the air intake duct 9443 through the air intake pipe 9444, then passes through the first filter screen 9445 and enters the tank shell 91. The air passes through the molecular sieve particles, and the oxygen flows out from the upper outlet pipe 9345 and enters the gas storage chamber 7. The two sets of tank assemblies 9 operate alternately to achieve the effect of oxygen production.

[0058] When shut down, the control system puts the tank assembly 9 into a moisture-proof mode, and the upper and lower ends of the tank shell 91 are sealed to isolate the molecular sieve particles from the air. This prevents the molecular sieve particles from absorbing moisture from the air and becoming ineffective when the oxygen generator is not used for a long time, thus achieving a moisture-proof effect.

[0059] When the molecular sieve particles fail and need to be replaced, the control system puts the tank assembly 9 into the replacement mode. The control system activates the second electric telescopic rod 941. The output shaft of the second electric telescopic rod 941 drives the pressing assembly 94 to move up and down reciprocally. When the vibrating block 9423 in the bottom support ring 9422 encounters the protrusion on the corrugated groove 95, it will be pressed and retract into the bottom support ring 9422. When the vibrating block 9423 encounters the depression on the corrugated groove 95, it will rebound quickly under the elastic force of the vibration spring 9424 and slightly impact the tank shell 91. The tank shell 91 will vibrate after being impacted, and the vibrating block 9423 will encounter resistance when passing the protrusion. When the resistance is transmitted to the bottom support ring 9422 through the vibrating block 9423, it will cause the bottom support ring 9422 to decelerate. When the vibrating block 9423 passes the depression, the resistance disappears, and the bottom support ring 9422 resumes its speed, thereby causing the bottom support ring 9422 to move up and down at varying speeds. The variable speed up and down movement of the bottom support ring 9422 causes the failed molecular sieve particles on the bottom support ring 9422 to fall more violently. The discharge ramp 9427 on the bottom support ring 9422 causes the molecular sieve particles to converge towards the first discharge port 9426 on the regulating cylinder 9421. The vibration of the tank shell 91, combined with the shaking of the bottom support ring 9422, makes the discharge faster and more efficient. At the same time, it also disperses the agglomerated molecular sieve particles to prevent them from clogging the first discharge port 9426. The molecular sieve particles enter the second discharge port 9446 from the first discharge port 9426, and then enter the waste bin 62 from the discharge pipe 9442. The staff pulls out the waste box 63 and pours out the waste, thereby realizing the discharge of the failed molecular sieve particles.

[0060] After unloading, the control system aligns the baffle 9447 on the unloading pipe 9442 with the first unloading port 9426, sealing the first unloading port 9426. Workers pour new molecular sieve particles into the feeding hopper 61. The control system opens the first electric valve 66 on the side requiring material replacement. The molecular sieve particles fall from the discharge pipe 65 into the feed housing 921, and then from the vertical cylinder 9341 into the tank housing 91. The control system then activates the second electric telescopic rod 941. The output shaft of the second electric telescopic rod 941 drives the pressing assembly 94 to move up and down reciprocally. The vibration of the tank housing 91 and the bumping of the bottom support ring 9422 cause the new molecular sieve particles to... The particles are compacted by vibration, which also disperses the agglomerates of molecular sieve particles. After the molecular sieve particles are filled, the control system drives the upper pressure component 93 and the lower pressure component 94 to press the molecular sieve particles through the first electric telescopic rod 931 and the second electric telescopic rod 941, respectively. The upper pressure plate 932 presses the molecular sieve particles and overcomes the elastic force of the upper pressure spring 933 to drive the upper sliding rod 937 to retract. The bottom support ring 9422 presses the molecular sieve particles and overcomes the elastic force of the lower pressure spring 943 to drive the lower sliding rod 9425 to retract. Finally, the control system puts the tank assembly 9 into the moisture-proof mode, thereby completing the unloading and replacement of waste material in the entire molecular sieve assembly 6.
