Description
Technical Field
[0001] The present invention relates to the technical field of medical oxygen generators, and specifically to a medical oxygen generator with an oxygen-enriched atomization function. Background Art
[0002] The oxygen-enriched atomization medical oxygen generator is an important and indispensable device in the modern medical system, and plays a significant role in improving the quality of patients' lives, assisting in disease treatment, and ensuring life safety. The medical oxygen generator efficiently separates high-concentration oxygen from the air through advanced physical or chemical technologies, providing a stable and continuous oxygen supply for patients. By inhaling high-concentration oxygen, patients can significantly improve the body's oxygen-deficient state, relieve symptoms such as dyspnea, and thus improve the quality of life. The oxygen-enriched atomization oxygen generator adds an atomization function on the basis of the oxygen generator, enabling pure oxygen to be combined with atomized liquid medicine for specific treatments.
[0003] The core component of the oxygen generator is the molecular sieve. The molecular sieve is prone to being affected by moisture and becoming ineffective. An ineffective molecular sieve cannot effectively separate oxygen. Therefore, after the molecular sieve fails, it needs to be replaced. Currently, the replacement of the molecular sieve requires professional personnel to disassemble the molecular sieve tank, and then refill the molecular sieve particles after disassembly. This method has cumbersome steps and it is difficult for users to refill it by themselves. Summary of the Invention
[0004] The purpose of the present invention is to provide a medical oxygen generator with an oxygen-enriched atomization function to solve the problems raised in the prior art.
[0005] To achieve the above purpose, the present invention provides the following technical solution: A medical oxygen generator with an oxygen-enriched atomization function includes a chassis, on which an atomizer and a humidifying bottle are installed. Inside the chassis, a filter, a compressor, a condenser, and a gas storage chamber are respectively installed. Two groups of molecular sieve assemblies are installed inside the chassis. The filter is connected to the compressor through a pipeline, the compressor is connected to the condenser through a pipeline, the condenser is connected to the molecular sieve assembly through a pipeline, the molecular sieve assembly is connected to the gas storage chamber through a pipeline, and the gas storage chamber is connected to the atomizer and the humidifying bottle respectively through pipelines; The molecular sieve assembly includes a waste bin and a feeding hopper. Brackets are symmetrically installed on the waste bin, and a tank assembly is installed on the brackets. A telescopic hose is installed at the bottom of the tank assembly, and one end of the telescopic hose is connected to the waste bin. First electric valves are symmetrically installed on the feeding hopper, a feeding pipe is installed on the first electric valves, and the feeding pipe is connected to the tank assembly. The bottom end of the tank assembly is connected to the condenser through a pipeline, and the top end of the tank assembly is connected to the gas storage chamber through a pipeline.
[0006] A control system is provided inside the chassis, and the control system is used to control the entire medical oxygen generator.
[0007] The control system turns on the oxygen generator. The filter first filters the air. The filtered air is compressed by the compressor and then enters the condenser to cool down. The air enters the molecular sieve assembly from the condenser. The molecular sieve assembly blocks the nitrogen in the air and allows oxygen to pass through. Two groups of molecular sieve assemblies operate alternately. The separated oxygen enters the storage tank. The control system transports the oxygen from the storage tank to the humidifying bottle or nebulizer as needed. The nebulizer atomizes the liquid medicine using oxygen to achieve the function of oxygen-enriched atomization, while the humidifying bottle directly humidifies the oxygen to achieve the function of pure oxygen delivery.
[0008] Furthermore, the tank assembly includes a tank housing, which is installed on a bracket. A pressing assembly is slidably installed at the top of the tank housing, and a pressing-down assembly is installed at the bottom of the tank housing. A feeding assembly is installed on the tank housing. The feeding assembly is connected to the feeding pipe. The tank housing is provided with a corrugated groove. The pressing-down assembly is fitted into the corrugated groove. The pressing-down assembly is connected to the condenser through a pipe, and the pressing-down assembly is connected to a telescopic hose. The pressing assembly is slidably connected to the feeding assembly, and the pressing assembly is connected to the storage tank through a pipe.
[0009] The tank housing is filled with molecular sieve particles, which are used to separate oxygen.
[0010] Furthermore, a motor bracket is installed on the pressing-down assembly, and an adjusting motor is installed on the motor bracket. An adjusting gear is installed on the output shaft of the adjusting motor, and the adjusting gear is in meshing transmission with the pressing-down assembly.
[0011] During oxygen production, the control system enables the tank assembly to enter the oxygen production mode. The air cooled by the condenser enters the intake duct from the intake pipe, then passes through the first filter and enters the tank housing. The air passes through the molecular sieve particles, and the oxygen flows out from the upper outlet pipe and enters the storage tank. Two groups of tank assemblies operate alternately, thus achieving the effect of oxygen preparation.
[0012] When it is turned off, the control system enables the tank assembly to enter the moisture-proof mode. Both the upper and lower ends of the tank housing are sealed, isolating the molecular sieve particles from the air, and preventing the molecular sieve particles from absorbing moisture in the air and becoming ineffective when the oxygen generator is not used for a long time, thus achieving the moisture-proof effect.
[0013] Furthermore, the feeding assembly includes a feeding housing and a sliding block. A sliding rod is installed on the sliding block, and the sliding rod is slidably installed 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 the feeding housing is connected to the feeding pipe through the feeding hole. The feeding housing is slidably connected to the pressing assembly, and the sliding block is slidably connected to the pressing assembly.
[0014] Further, the upper pressing assembly includes a first electric telescopic rod, which is installed on the outer shell of the tank body. The output shaft of the first electric telescopic rod penetrates through the outer shell of the tank body and is equipped with an upper tray. An upper sliding rod is slidably installed on the upper tray. The bottom end of the upper sliding rod is equipped with an upper pressing plate. An upper pressing spring is installed between the upper pressing plate and the upper tray. A blanking cylinder is slidably installed on the upper tray. The blanking cylinder is slidably connected to the feeding outer shell. A blanking spring is installed between the blanking cylinder and the upper tray. The blanking cylinder is slidably connected to the sliding block. The blanking cylinder is slidably connected to the upper pressing plate. The upper pressing plate is slidably connected to the outer shell of the tank body.
[0015] The control system drives the upper pressing assembly to slide up and down in the outer shell of the tank body through the first electric telescopic rod. When the oxygen generator is producing oxygen, the first electric telescopic rod makes the vertical cylinder on the upper pressing assembly not contact the sliding block, and the tank body assembly enters the oxygen production mode. At this time, under the action of the blanking spring, the bottom plate is tightly fitted with the upper pressing plate, and the second electric valve on the air outlet pipe is opened, and the separated oxygen can flow out from the air outlet pipe; when the oxygen generator is turned off, the second electric valve on the air outlet pipe is closed, and external gas cannot enter the outer shell of the tank body through the air outlet pipe. The first electric valve is closed, and external air cannot enter the outer shell of the tank body through the feeding hole. The two sliding blocks are tightly fitted under the action of the feeding spring to isolate the air, and the tank body assembly enters the moisture-proof mode to achieve the purpose of isolating the air and preventing the molecular sieve particles from being affected by moisture and failing.
[0016] When the molecular sieve particles are used for a long time or are affected by moisture and fail, the first electric telescopic rod drives the upper pressing assembly to retract, and the upper tray drives the vertical cylinder to move upward. The inclined plane on the vertical cylinder presses the sliding block. After being squeezed, the two sliding blocks slide horizontally and move away from each other until the vertical cylinder passes through. When the limit disk on the vertical cylinder contacts the top end of the outer shell of the tank body, the vertical cylinder is limited and cannot move upward. At this time, the upper tray overcomes the elastic force of the blanking spring and generates a relative upward displacement with the vertical cylinder. The upper sliding rod and the upper pressing plate on the upper tray follow the upper tray to generate a relative upward displacement with respect to the vertical cylinder. The relative displacement between the upper pressing plate and the vertical cylinder causes the bottom plate at the bottom of the vertical cylinder to disengage from the upper pressing plate and makes the discharge hole pass through the upper pressing plate. The tank body assembly enters the replacement mode. When new molecular sieve particles enter from the feeding hole, they will fall from the feeding outer shell into the vertical cylinder and then fall into the outer shell of the tank body from the discharge hole at the bottom end of the vertical cylinder to achieve the effect of material replacement.
[0017] Further, the blanking cylinder includes a vertical cylinder, which is slidably connected to the feeding outer shell. The vertical cylinder is provided with an inclined plane. A limit disk is installed on the vertical cylinder. A blanking spring is installed between the limit disk and the upper tray. The vertical cylinder is slidably connected to the upper tray. The vertical cylinder is slidably connected to the upper pressing plate. The bottom end of the vertical cylinder is provided with a discharge hole. A bottom plate is installed at the bottom end of the vertical cylinder. An air outlet pipe is installed on the bottom plate. The bottom end of the air outlet pipe is flush with the bottom end of the bottom plate. A second filter screen is provided at the bottom end of the air outlet pipe. A second electric valve is installed in the air outlet pipe.
[0018] Furthermore, the pressing-down component includes a second electric telescopic rod installed at the bottom end of the tank body shell. A lower tray is installed on the output shaft of the second electric telescopic rod. A vibrating bottom support component is slidably installed on the lower tray. A pressing-down spring is installed between the vibrating bottom support component and the lower tray. A discharging pipe fitting is rotatably installed inside the vibrating bottom support component. The discharging pipe fitting is movably connected to the tank body shell. A motor support is installed on the vibrating bottom support component. The discharging pipe fitting is in meshing transmission with an adjusting gear. The discharging pipe fitting is communicated with a condenser through a pipeline. A telescopic hose is connected to the discharging pipe fitting.
[0019] Furthermore, the vibrating bottom support component includes a bottom support ring. A blanking slope is provided on the bottom support ring. An adjusting cylinder is installed on the bottom support ring. A number of first discharging ports are equidistantly provided on the adjusting cylinder. A number of vibrating blocks are slidably installed inside the bottom support ring. The vibrating blocks are fitted with corrugated grooves. A vibrating spring is provided between the vibrating blocks and the bottom support ring. A number of downward sliding rods are installed at the bottom end of the bottom support ring. The downward sliding rods are slidably installed on the lower tray. A motor support is installed at the bottom end of the bottom support ring. The discharging pipe fitting is rotatably installed inside the adjusting cylinder. The bottom support ring is slidably connected to the tank body shell. A pressing-down spring is installed between the bottom support ring and the lower tray.
[0020] When the molecular sieve particles fail and need to be replaced, the control system enables the tank body component to enter the replacement mode. The control system turns on the second electric telescopic rod. The output shaft of the second electric telescopic rod drives the pressing-down component to move up and down reciprocally. When the vibrating blocks inside the bottom support ring encounter the protrusions on the corrugated grooves, they will be pressed and retracted into the bottom support ring. When the vibrating blocks encounter the depressions on the corrugated grooves, they will quickly rebound under the elastic force of the vibrating spring and slightly impact the tank body shell. When the tank body shell is impacted, vibrations will occur. And when the vibrating blocks pass through the protrusions, they will encounter resistance. When the resistance is transmitted to the bottom support ring through the vibrating blocks, it will cause the bottom support ring to decelerate. When the vibrating blocks pass through the depressions, the resistance disappears and the bottom support ring resumes its speed, thereby causing the bottom support ring to produce variable-speed reciprocating up and down movements. The variable-speed up and down movement of the bottom support ring makes the failed molecular sieve particles on the bottom support ring fall more violently and bumpily. The blanking slope on the bottom support ring causes the molecular sieve particles to converge towards the first discharging ports on the adjusting cylinder. The vibration of the tank body shell in cooperation with the bumpy bottom support ring makes the blanking faster and more efficient. At the same time, it also vibrates and disperses the agglomerated molecular sieve particles to prevent them from blocking the first discharging ports. The molecular sieve particles enter the second discharging ports from the first discharging ports, and then enter the waste bin through the discharging pipeline. The staff pulls out the waste extraction box and pours out the waste, thereby realizing the discharging of the failed molecular sieve particles.
[0021] After discharging, the control system aligns the baffle on the discharge pipe with the first discharge port to complete the sealing of the first discharge port. The staff pours new molecular sieve particles into the feeding hopper. The control system opens the first electric valve on the side where the material needs to be replaced. The molecular sieve particles fall from the feeding pipe into the feeding housing and then fall into the tank housing from the vertical cylinder. The control system activates the second electric telescopic rod again. The output shaft of the second electric telescopic rod drives the pressing assembly to move up and down reciprocally. The vibration of the tank housing and the bumping of the bottom support ring cause the new molecular sieve particles to be vibrated and compacted, and at the same time, the agglomerates of the molecular sieve particles are also dispersed. After the filling of the molecular sieve particles is completed, the control system drives the upper pressing assembly and the lower pressing assembly to compress the molecular sieve particles through the first electric telescopic rod and the second electric telescopic rod respectively. The upper pressing plate compresses the molecular sieve particles and drives the upper sliding rod to retract against the elastic force of the upper pressing spring. The bottom support ring compresses the molecular sieve particles and drives the lower sliding rod to retract against the elastic force of the lower pressing spring. Finally, the control system enables the tank assembly to enter the moisture-proof mode, thus completing the discharge and replacement of the waste of the entire molecular sieve assembly.
[0022] Further, the discharge pipe fitting includes a discharge pipe which is rotatably installed in the adjusting cylinder. One end of the discharge pipe is connected with a telescopic hose. An adjusting gear ring is installed on the discharge pipe. The adjusting gear ring is in meshing transmission with the adjusting gear. An air inlet pipe is installed in the discharge pipe. A number of air inlet channels are installed on the air inlet pipe. The air inlet channels are connected with the discharge pipe. One end of the air inlet pipe penetrates through the discharge pipe and is connected with a condenser through a pipe. A number of second discharge ports are provided at one end of the discharge pipe. The size and quantity of the second discharge ports correspond to the size of the first discharge port. A number of first filter meshes are provided on the discharge pipe. The position and quantity of the first filter meshes correspond to the air inlet channels. A baffle is provided on the discharge pipe. The baffle is located on one side of the first filter mesh, and the second discharge port is located on the other side of the first filter mesh.
[0023] The control system drives the adjusting gear to rotate through the adjusting motor. The adjusting gear drives the discharge pipe to rotate through the adjusting gear ring. When the oxygen generator is producing oxygen, the control system positions the first filter mesh on the discharge pipe in the middle of the first discharge port. The tank assembly enters the oxygen production mode. At this time, air enters the air inlet channels from the air inlet pipe and then passes through the first filter mesh from the air inlet channels into the tank housing. The first filter mesh is used to block the molecular sieve particles and allow air to pass through. When the oxygen generator is turned off, the control system aligns the baffle on the discharge pipe with the first discharge port. The tank assembly enters the moisture-proof mode. 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. When the molecular sieve particles become ineffective after long-term use or being affected by moisture, the control system aligns the second discharge port on the discharge pipe with the first discharge port. The tank assembly enters the replacement mode. At this time, the ineffective molecular sieve particles can pass through the first discharge port and the second discharge port, and the molecular sieve particles fall through the gap between the air inlet pipe and the discharge pipe.
[0024] Further, a waste extraction box is slidably installed on the waste bin.
[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0026] 1. In the oxygen generation mode, air enters from the air inlet duct and flows into the storage bin through the air outlet pipe. The two groups of tank body components operate alternately, so as to achieve the effect of oxygen preparation. In the moisture-proof mode, by closing the second electric valve and the first electric valve, external gas cannot enter the tank body shell through the air outlet pipe or the feeding hole. The two sliding blocks are tightly attached under the action of the feeding spring to isolate air. The control system aligns the baffle on the discharging pipeline with the first discharging port. At this time, the first discharging port is blocked by the baffle, so that air is isolated by the baffle, preventing the molecular sieve particles from contacting air and achieving the purpose of sealing and moisture-proof.
[0027] 2. The second electric telescopic rod drives the pressing component to reciprocate, cooperating with the vibration block, so that the bottom supporting ring moves up and down reciprocally at a variable speed, and the tank body shell is impacted to generate vibration. The variable-speed up-and-down movement of the bottom supporting ring makes the ineffective molecular sieve particles on the bottom supporting ring jolt and fall more violently. The feeding slope on the bottom supporting ring makes the molecular sieve particles converge towards the first discharging port on the adjusting cylinder. The vibration of the tank body shell and the jolting bottom supporting ring make the feeding faster and more efficient. At the same time, the agglomerated molecular sieve particles are also shaken loose, achieving the purpose of quickly discharging the ineffective molecular sieve particles to prevent blockage. The vibration of the tank body shell and the jolting of the bottom supporting ring also make the new molecular sieve particles vibrated and compacted, and at the same time, the agglomerated molecular sieve particles are shaken loose, achieving the purpose of filling the molecular sieve particles.
[0028] 3. According to the requirements of different modes of the tank body component, the adjusting motor is used to drive the discharging pipe fitting to rotate, so that the discharging pipe fitting cooperates with the vibrating bottom supporting component to change different forms; the first electric telescopic rod is used to drive the pressing component to move to different positions in the tank body shell, so that the pressing component switches different forms according to the requirements of different modes of the tank body component, thereby achieving the purpose of multi-mode switching of the tank body component.

[0046] The feeding assembly 92 includes a feeding housing 921 and a sliding block 922, a sliding rod 924 is installed on the sliding block 922, the sliding rod 924 is slidably installed on the feeding housing 921, a feeding spring 923 is installed between the sliding block 922 and the feeding housing 921, a feeding hole 925 is provided on the feeding housing 921, the feeding housing 921 is connected to the feeding pipe 65 through the feeding hole 925, the feeding housing 921 is slidably connected to the upper pressing assembly 93, and the sliding block 922 is slidably connected to the upper pressing assembly 93.
[0047] The upper pressing assembly 93 includes a first electric telescopic rod 931. The first electric telescopic rod 931 is installed on the tank shell 91. The output shaft of the first electric telescopic rod 931 penetrates through the tank shell 91 and is equipped with an upper tray 936. An upper sliding rod 937 is slidably installed on the upper tray 936. The bottom end of the upper sliding rod 937 is installed with an upper pressing plate 932. An upper pressing spring 933 is installed between the upper pressing plate 932 and the upper tray 936. A blanking cylinder 934 is slidably installed on the upper tray 936. The blanking cylinder 934 is slidably connected to the feeding housing 921. A blanking spring 935 is installed between the blanking cylinder 934 and the upper tray 936. The blanking cylinder 934 is slidably connected to the sliding block 922. The blanking cylinder 934 is slidably connected to the upper pressing plate 932. The upper pressing plate 932 is slidably connected to the tank shell 91.
[0048] The control system drives the upper pressing assembly 93 to slide up and down in the tank shell 91 through the first electric telescopic rod 931. When the oxygen generator is generating oxygen, the first electric telescopic rod 931 makes the vertical cylinder 9341 on the upper pressing assembly 93 not contact the sliding block 922, and the tank assembly 9 enters the oxygen generation mode. At this time, under the action of the blanking spring 935, the bottom plate 9344 is tightly fitted with the upper pressing plate 932, and the second electric valve on the air outlet pipe 9345 is opened, and the separated oxygen can flow out from the air outlet pipe 9345; when the oxygen generator is turned off, the second electric valve on the air outlet pipe 9345 is closed, and external gas cannot enter the tank shell 91 through the air outlet pipe 9345. The first electric valve 66 is closed, and external air cannot enter the tank shell 91 through the feeding hole 925. The two sliding blocks 922 are tightly fitted under the action of the feeding spring 923 to isolate the air, and the tank assembly 9 enters the moisture-proof mode to achieve the purpose of isolating the air and preventing the molecular sieve particles from being affected by moisture and becoming ineffective;
[0049] When the molecular sieve particles are used for a long time or become ineffective due to moisture, the first electric telescopic rod 931 drives the upper pressing assembly 93 to retract. The upper tray 936 drives the vertical cylinder 9341 to move upward. The inclined plane 9342 on the vertical cylinder 9341 squeezes the sliding block 922. After the two sliding blocks 922 are squeezed, they slide horizontally and move away from each other until the vertical cylinder 9341 passes through. When the limit disk 9346 on the vertical cylinder 9341 contacts the top end 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 blanking spring 935 and generates a relative upward displacement with the vertical cylinder 9341. The upper sliding rod 937 and the upper pressing disk 932 on the upper tray 936 follow the upper tray 936 to generate a relative upward displacement with respect to the vertical cylinder 9341. The relative displacement between the upper pressing disk 932 and the vertical cylinder 9341 causes the bottom plate 9344 at the bottom of the vertical cylinder 9341 to disengage from the engagement with the upper pressing disk 932, and the discharge hole 9343 passes through the upper pressing disk 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 housing 921 into the vertical cylinder 9341, and then fall into the tank shell 91 from the discharge hole 9343 at the bottom end of the vertical cylinder 9341, achieving the effect of material replacement.
[0050] The blanking cylinder 934 includes a vertical cylinder 9341. The vertical cylinder 9341 is slidably connected to the feed housing 921. An inclined plane 9342 is provided on the vertical cylinder 9341. A limit disk 9346 is installed on the vertical cylinder 9341. A blanking spring 935 is installed between the limit disk 9346 and the upper tray 936. The vertical cylinder 9341 is slidably connected to the upper tray 936. The vertical cylinder 9341 is slidably connected to the upper pressing disk 932. A discharge hole 9343 is provided at the bottom end of the vertical cylinder 9341. A bottom plate 9344 is installed at the bottom end of the vertical cylinder 9341. An air outlet pipe 9345 is installed on the bottom plate 9344.

An adjusting cylinder 9421 is installed on the bottom support ring 9422. A number of first discharge openings 9426 are equidistantly provided on the adjusting cylinder 9421. A number of vibrating blocks 9423 are slidably installed inside the bottom support ring 9422. The vibrating blocks 9423 are engaged with the corrugated grooves 95.

A number of downward sliding rods 9425 are installed at the bottom end of the bottom support ring 9422. The downward sliding rods 9425 are slidably installed on the lower tray 945. A motor bracket 96 is installed at the bottom end of the bottom support ring 9422. A discharge pipe fitting 944 is rotatably installed inside the adjusting cylinder 9421. The bottom support ring 9422 is slidably connected to the tank body shell 91. A downward pressing spring 943 is installed between the bottom support ring 9422 and the lower tray 945.
[0053] The discharge pipe fitting 944 includes a discharge pipe 9442, which is rotatably installed inside the adjusting cylinder 9421. One end of the discharge pipe 9442 is connected to a telescopic hose 67. An adjusting gear ring 9441 is installed on the discharge pipe 9442. The adjusting gear ring 9441 is engaged with an adjusting gear 97 for transmission. An air inlet pipe 9444 is installed inside the discharge pipe 9442. A number of air inlet channels 9443 are installed on the air inlet pipe 9444. The air inlet channels 9443 are connected to the discharge pipe 9442. One end of the air inlet pipe 9444 penetrates through the discharge pipe 9442 and is connected to the condenser 5 through a pipe. A number of second discharge openings 9446 are provided at one end of the discharge pipe 9442.

[0054] The control system drives the adjusting gear 97 to rotate by adjusting the motor 98. The adjusting gear 97 drives the discharging pipeline 9442 to rotate through the adjusting gear ring 9441. When the oxygen generator is producing oxygen, the control system positions the first filter screen 9445 on the discharging pipeline 9442 at the middle position of the first discharging port 9426. The tank body assembly 9 enters the oxygen production mode. At this time, air enters the air inlet channel 9443 from the air inlet pipe 9444, and then passes through the first filter screen 9445 from the air inlet channel 9443 and enters the tank body shell 91. The first filter screen 9445 is used to block the molecular sieve particles and allow air to pass through. When the oxygen generator is turned off, the control system aligns the baffle 9447 on the discharging pipeline 9442 with the first discharging port 9426. The tank body assembly 9 enters the moisture-proof mode. At this time, the first discharging port 9426 is blocked by the baffle 9447, isolating the air, preventing the molecular sieve particles from contacting the air. When the molecular sieve particles become ineffective due to long-term use or moisture absorption, the control system aligns the second discharging port 9446 on the discharging pipeline 9442 with the first discharging port 9426. The tank body assembly 9 enters the replacement mode. At this time, the ineffective molecular sieve particles can pass through the first discharging port 9426 and the second discharging port 9446, and the molecular sieve particles fall through the gap between the air inlet pipe 9444 and the discharging pipeline 9442.
[0055] A waste material extraction box 63 is slidably installed on the waste material bin 62.
[0056] The working principle of the present invention: The control system starts 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 to cool down. The air enters the molecular sieve assembly 6 from the condenser 5. The molecular sieve assembly 6 blocks the nitrogen in the air and allows oxygen to pass through. The two groups of molecular sieve assemblies 6 operate alternately. The separated oxygen enters the gas storage tank 7. The control system transports the oxygen from the gas storage tank 7 to the humidifying bottle 8 or the atomizer 2 as needed. The atomizer 2 atomizes the liquid medicine using oxygen to achieve the function of oxygen-rich atomization. The humidifying bottle 8 directly humidifies the oxygen to achieve the function of pure oxygen delivery.
[0057] During oxygen production, the control system makes the tank body assembly 9 enter the oxygen production mode. The air cooled by the condenser 5 enters the air inlet channel 9443 from the air inlet pipe 9444, and then passes through the first filter screen 9445 and enters the tank body shell 91. The air passes through the molecular sieve particles, and oxygen flows out from the upper outlet pipe 9345 and enters the gas storage tank 7. The two groups of tank body assemblies 9 operate alternately, so as to achieve the effect of oxygen preparation.
[0058] When it is turned off, the control system makes the tank body assembly 9 enter the moisture-proof mode. Both the upper and lower ends of the tank body shell 91 are sealed, isolating the molecular sieve particles from the air, avoiding the molecular sieve particles absorbing air moisture and becoming ineffective when the oxygen generator is not used for a long time, thus achieving the moisture-proof effect.
[0059] When the molecular sieve particles fail and need to be replaced, the control system causes the tank assembly 9 to enter the replacement mode, and the control system turns on the second electric telescopic rod 941. The output shaft of the second electric telescopic rod 941 drives the downward pressure assembly 94 to move up and down. When the vibration block 9423 in the bottom support ring 9422 encounters the protrusion on the corrugated groove 95, it will be compressed and retracted into the bottom support ring 9422. When the vibration 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 hit the tank shell 91. The tank shell 91 will vibrate after being hit, and the vibration block 9423 will encounter resistance when passing through the protrusion. When the resistance is transmitted to the bottom support ring 9422 through the vibration block 9423, the bottom support ring 9422 will be decelerated. When the vibration block 9423 passes through the depression, the resistance disappears, and the bottom support ring 9422 recovers its speed, thereby causing the bottom support ring 9422 to move back and forth at a variable speed. The bottom support ring 9422 moves up and down at a variable speed, causing the failed molecular sieve particles on the bottom support ring 9422 to bump and fall more violently. The unloading slope 9427 on the bottom support ring 9422 causes the molecular sieve particles to converge to the first unloading port 9426 on the regulating cylinder 9421. The vibration of the tank shell 91 and the bumpy bottom support ring 9422 make the unloading faster and more efficient, and also disperse the aggregated molecular sieve particles to prevent them from clogging the first unloading port 9426. The molecular sieve particles enter the second unloading port 9446 from the first unloading port 9426, and then enter the waste bin 62 from the unloading pipe 9442. The staff draws out the waste extraction box 63 and pours out the waste, thereby realizing the unloading 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 to complete the blocking of the first unloading port 9426. The staff pours new molecular sieve particles into the upper hopper 61. The control system opens the first electric valve 66 on the side where the material needs to be changed. The molecular sieve particles fall from the discharge pipe 65 into the feed shell 921, and then fall from the vertical cylinder 9341 into the tank shell 91. The control system opens the second electric telescopic rod 941 again. The output shaft of the second electric telescopic rod 941 drives the pressing assembly 94 to reciprocate up and down. The vibration of the tank shell 91 and the bumps of the bottom support ring 9422 make the new molecular sieve The particles are vibrated and compacted, and the agglomerates of the molecular sieve particles are also vibrated and dispersed. After the molecular sieve particles are filled, the control system drives the upper pressure assembly 93 and the lower pressure assembly 94 to compress the molecular sieve particles through the first electric telescopic rod 931 and the second electric telescopic rod 941 respectively. The upper pressure plate 932 compresses the molecular sieve particles and overcomes the elastic force of the upper pressure spring 933 to drive the upper slide bar 937 to retract. The bottom support ring 9422 compresses the molecular sieve particles and overcomes the elastic force of the lower pressure spring 943 to drive the lower slide bar 9425 to retract. Finally, the control system causes the tank assembly 9 to enter the moisture-proof mode, thereby completing the unloading and replacement of the waste material of the entire molecular sieve assembly 6.
