Description

Technical Field

[0001] The invention relates to the field of oxygen concentrators, and in particular to an oxygen concentrator capable of reducing infrared radiation. Background Art

[0002] Portable oxygen concentrators are oxygen concentrators that are easy to carry or transport. They have the same oxygen production effect and similar principles as desktop oxygen concentrators. Currently, the most common portable oxygen concentrators on the market use a compressor to compress the external gas, and then use a molecular sieve to intercept the nitrogen atoms in the air, thereby obtaining high-purity oxygen in the air.

[0003] The core of the oxygen generator to produce high-purity oxygen is that the molecular sieve cylinder inside it is filled with zeolite fillers or fillers made of chemical substances such as aluminosilicate and silicate; During repeated use, the filling material inside the molecular sieve cartridge may become clogged due to excessive interception of nitrogen atoms. When this happens, the nitrogen atom interception effect will decrease, thereby causing a decrease in oxygen quality. At this time, the filling material inside the molecular sieve cartridge needs to be replaced.

[0004] The existing oxygen concentrator uses a double molecular sieve cartridge, and both molecular sieves are installed inside the oxygen concentrator, and the two molecular sieve cartridges need to be connected to the gas and exhaust pipes. When replacing, it is necessary to first remove the outer shell of the oxygen concentrator, and then remove the air inlet and outlet pipes connected to the molecular sieves. The disassembly and installation are very cumbersome and inconvenient. In addition, since this type of oxygen concentrator is carried by the user, the radiation generated by the oxygen concentrator will cause certain harm to the human body. In order to solve the above problems, we propose an oxygen concentrator that reduces infrared radiation. Summary of the invention

[0005] The purpose of the present invention is to provide an oxygen concentrator capable of reducing infrared radiation, which has the advantage of being easy to disassemble and assemble the molecular sieve.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: an oxygen concentrator for reducing infrared radiation, comprising a shell, a compressor cover is fixedly installed at the bottom of the inner cavity of the shell, and the inner walls of the shell and the compressor cover are coated with a silver layer to reduce their infrared radiation; an air compression mechanism is installed inside the compressor cover; two sealing components are fixedly connected to the bottom of the inner cavity of the shell, and a molecular sieve component is arranged inside the sealing component; a linkage component is installed inside the sealing component; two thread grooves are opened on the top of the shell, and two limit thread covers threadedly connected to the thread grooves are arranged on the top of the shell; a controller is installed on the top of the shell.

[0007] By adopting the above technical solution, the two molecular sieve cartridges can be directly pulled out of the mounting seat by changing the disassembly and assembly method of the two molecular sieve cartridges to from top to bottom. During the withdrawal process, the air compression mechanism and the sealing assembly can actively separate the air inlet pipeline and the air outlet pipeline. During the insertion process, the air compression mechanism and the sealing assembly can actively connect and seal the air inlet pipeline and the air outlet pipeline. There is no need to disassemble and assemble the oxygen generator casing or the various pipelines on the molecular sieve throughout the process. Compared with the disassembly and assembly process of the traditional molecular sieve, the process is simpler and more convenient. Moreover, by utilizing the two molecular sieve structures of the oxygen generator itself and the dual-channel valve control structure, the other molecular sieve can be removed during the working process of one molecular sieve to replace its internal filler, which will not affect the normal operation of the oxygen generator. This operation is suitable for patients who need oxygen from an oxygen generator for a long time.

[0008] The present invention is further configured as follows: the air compression mechanism comprises an air compressor, an air inlet end of the air compressor is connected to an air inlet pipe, and an air outlet end of the air compressor is connected to an air outlet pipe; One end of the air outlet pipe is connected to a three-way solenoid valve, and two ends of the three-way solenoid valve are respectively connected to a first inlet pipe and a second inlet pipe; One end of each of the first inlet pipe and the second inlet pipe is connected to a telescopic pipe, and one end of the telescopic pipe is provided with a driving assembly.

[0009] The above technical solution is adopted to compress the air and input the air into the interior of the molecular sieve cylinder through the setting of the air compression mechanism.

[0010] Specifically, the air compressor is started to generate suction, and the outside air is sucked into the air compressor through the air inlet pipe, the compressor filter, and the air filter for compression. The compressed gas is input into the three-way solenoid valve through the air outlet pipe. The three-way solenoid valve has two channels that can flow and be closed separately; the air can flow separately to allow the air to enter the first inlet pipe and the telescopic tube, movable tube, connecting seat, filter seat, and molecular sieve cylinder connected to the first inlet pipe, and the air can also flow separately to allow the air to enter the second inlet pipe and the telescopic tube, movable tube, connecting seat, filter seat, and molecular sieve cylinder connected to the second inlet pipe.

[0011] The two flow channels inside the three-way solenoid valve are respectively connected to the second inlet pipe and the telescopic pipe. The three-way solenoid valve can independently control one flow channel to flow and the other flow channel to close, which is the prior art and will not be described in detail here. The air compressor is driven by PWM, and the model of the air compressor is ZR1-02-01.

[0012] The present invention is further configured as follows: the driving assembly includes a movable tube, one end of the movable tube is connected to the telescopic tube, a tooth plate 1 is fixedly connected to the lower surface of the movable tube, the tooth plate 1 is meshed with a gear, and the gear is meshed with a tooth plate 2.

[0013] The above technical solution is adopted, through the setting of the driving component, to drive the connecting seat and the molecular sieve cylinder to contact and form a seal through the downward pressure of the molecular sieve cylinder.

[0014] Specifically, when the molecular sieve cylinder is pressed down to push the connecting plate and the second tooth plate down, the second tooth plate will drive the gear meshing with it to rotate clockwise, and the clockwise rotation of the gear will drive the first tooth plate meshing with it to drive the movable tube and the connecting seat to move closer to the molecular sieve cylinder.

[0015] When the bottom of the connecting plate is completely in contact with the bottom of the inner cavity of the mounting seat, the silicone sealing sleeve will be sleeved on the filter seat, and the silicone sealing sleeve will also contact the surface of the molecular sieve cartridge to form a seal.

[0016] At this time, the gas input from the movable tube can enter the interior of the molecular sieve cylinder through the silicone sealing sleeve, filter seat, and filter screen. Since the top of the molecular sieve cylinder is sealed by a threaded cover plate, the gas inside the molecular sieve cylinder can only pass downward through the filler, sealing joint 2, sealing groove, sealing joint 1, and the delivery pipe.

[0017] When the molecular sieve cylinder is pulled out, the connecting plate rebounds and moves upward under the action of spring 2, and the connecting plate will drive tooth plate 2 upward, and tooth plate 2 will drive the gear meshing with it to rotate counterclockwise, and the gear will drive tooth plate 1 to drive the movable tube and the connecting seat to move outward, thereby separating the connecting seat and the molecular sieve cylinder.

[0018] It should be noted that the silicone sealing sleeve is rubber and has toughness. When the silicone sealing sleeve contacts the filter seat, the filter seat can force the silicone sealing sleeve to deform. When the center points of the filter seat and the silicone sealing sleeve correspond, the filter seat will not contact the silicone sealing sleeve, and the silicone sealing sleeve will recover its shape and contact the surface of the molecular sieve tube to form a seal.

[0019] Secondly, the telescopic tube can be extended and retracted. When the connecting seat moves toward the molecular sieve cylinder, the telescopic tube will extend in length. When the connecting seat and the molecular sieve cylinder move away from each other, the telescopic tube will fold and retract.

[0020] The telescopic tube is specifically a telescopic bellows.

[0021] The present invention is further configured as follows: the sealing assembly comprises a mounting seat, a connecting seat is provided inside the mounting seat, the connecting seat is communicated with the movable pipe, and a silicone sealing sleeve is fixedly sleeved inside the connecting seat; The side of the mounting seat close to the gear is mounted on the gear through a bracket; The outer side of the mounting seat is provided with a guide groove which is set with the movable tube and the tooth plate; A delivery pipe is embedded in the bottom of the inner cavity of the mounting seat, one end of the delivery pipe passes through the outside of the mounting seat, and the other end of the delivery pipe is connected to a sealing joint 1.

[0022] By adopting the above technical solution, through the setting of the sealing component, the silicone sealing sleeve is used to contact the surface of the molecular sieve cartridge and set the filter seat sleeve inside, the silicone sealing sleeve and the molecular sieve cartridge are in contact to form a seal, and the silicone sealing sleeve sets the filter seat sleeve to form a seal, so that the gas in the movable tube can enter the interior of the molecular sieve cartridge through the filter seat; A silicone sealing sleeve is provided inside the connection seat, and the silicone sealing sleeve is used to contact the surface of the molecular sieve cylinder and play a sealing role; The sealing joint 1 is used to form a connection with and seal the bottom of the sealing groove, and the delivery pipe is used to deliver the oxygen after the nitrogen is intercepted by the filler.

[0023] The present invention is further configured as follows: the molecular sieve assembly comprises a molecular sieve cartridge, the interior of the molecular sieve cartridge is filled with a filler, a pressing plate is slidably connected to the interior of the molecular sieve cartridge, a spring 1 is provided on the top of the pressing plate, a threaded cover plate threadedly connected to the molecular sieve cartridge is provided on the top of the spring 1, and a sealing joint 2 is connected to the bottom of the molecular sieve cartridge; The surface of the molecular sieve cartridge is threadedly connected with a filter seat, and the interior of the filter seat is fixedly sleeved with a filter screen.

[0024] The above technical solution is used to intercept nitrogen in compressed gas by setting a molecular sieve component; After filling the molecular sieve cylinder with fillers, put the pressure plate into the molecular sieve cylinder, place spring 1 on the top of the pressure plate, press spring 1 down with the threaded cover plate, and thread the threaded cover plate and the molecular sieve cylinder together. Since spring 1 is compressed and produces rebound force when pressed down, and the threaded cover plate and the mounting seat are threadedly connected, the rebound force of spring 1 cannot act upward but only downward. At this time, the rebound force of spring 1 will push the pressure plate down to compact the fillers.

[0025] The present invention is further configured as follows: the linkage assembly includes a connecting plate, one side of the connecting plate is fixedly connected to the second tooth plate, the top of the connecting plate is fixedly connected to the second spring via a spring fixing member, the top of the second spring is fixedly connected to the fixing plate via a spring fixing member, and the surface of the fixing plate is fixedly connected to the inner wall of the mounting seat; A sealing groove is provided inside the connecting plate.

[0026] The above technical solution is adopted, through the setting of the linkage component, to receive the molecular sieve cartridge and as the molecular sieve cartridge is pressed down, the tooth plate 2 is driven to move downward and the sealing joint 2 and the sealing joint 1 can be connected to the sealing groove to form a seal.

[0027] Specifically, when the molecular sieve cartridge is inserted into the mounting seat and its bottom is connected to the top of the sealing groove to form a seal, the molecular sieve cartridge continues to press downward, driving the connecting plate downward, and the connecting plate downward drives the tooth plate 2 downward, and at the same time pulls the spring 2 to extend and generate a rebound force; When the bottom of the connecting plate contacts the bottom of the inner cavity of the mounting seat, the bottom of the sealing groove is connected to the sealing joint and forms a seal; It should be noted that the rebound force of the extended spring 2 is sufficient to push the weight of the molecular sieve cylinder and its internal filler upward; the model of the spring 2 is not limited here, and the rebound force is sufficient to push the molecular sieve cylinder and the filler upward.

[0028] The present invention is further configured as follows: a circuit board is installed inside the housing, an oxygen purity monitor is installed on the top of the circuit board, an inlet of the oxygen purity monitor is connected to a connecting pipe, an outlet of the oxygen purity monitor is connected to an air outlet pipe, one end of the connecting pipe is connected to a flow monitoring sensor, and the bottom of the flow monitoring sensor is connected to a connecting pipe; The bottom of the connecting pipe is connected to an air storage bin, and the two sides of the air storage bin are connected to two sealing joints; A one-way valve is installed inside the first sealing joint.

[0029] With the above technical solution, the circuit board is used to issue the opening and closing of the inside of the three-way solenoid valve and to receive instructions issued by the controller and execute the instructions issued by the controller; Oxygen purity monitor is used to monitor oxygen purity; The connecting tube is used to input oxygen into the oxygen purity monitor; The outlet pipe is used to input oxygen that has been monitored for oxygen purity into the outside world; The flow monitoring sensor is used to monitor the oxygen exhaust flow; The connecting tube is used to input oxygen into the interior of the flow monitoring sensor; The gas storage tank is used to store oxygen; The gas flow direction of the one-way valve is from the sealing joint to the gas storage tank, which can ensure that the oxygen delivered by the two sealing joints will not flow back; it can ensure that after the oxygen enters the gas storage tank, it can only be input upward through the connecting pipe into the interior of the flow monitoring sensor.

[0030] The present invention is further configured as follows: one end of the air outlet pipe is connected to an air pipe joint, and the top end of the air pipe joint penetrates to the top of the housing; The top end of the air inlet pipe is connected to a compressor filter, and the air inlet of the compressor filter is connected to an air filter.

[0031] The above technical solution is adopted, through the setting of the tracheal joint, for connecting with the oxygen supply pipe, and the oxygen supply pipe is used to connect with the patient for the patient to absorb oxygen; Through the setting of compressor filter and air filter, the air filter is used for preliminary filtering of impurities in the outside air; the compressor filter is used for secondary filtering of impurities in the air; and is used to increase the oxygen content in the air.

[0032] The present invention is further configured as follows: a slide groove is provided inside the mounting seat, a sliding block slidably connected to the slide groove is fixedly connected to the surface of the molecular sieve cartridge; and a through groove is also provided inside the mounting seat.

[0033] By adopting the above technical solution, through the setting of the slide groove and the slider, the slide groove and the slider are slidably connected. When the molecular sieve cartridge is inserted into the interior of the mounting seat, the slide groove and the slider are slidably connected to ensure that the filter seat can accurately pass through the through groove; and the slide groove and the slider also have the function of limiting the rotation of the molecular sieve cartridge, which can ensure that after the filter seat enters the interior of the mounting seat, it can accurately correspond to the movable tube connected to the inside of the connecting seat.

[0034] The present invention is further configured as follows: a guide groove slidably connected to the connecting plate is provided on one side of the mounting seat.

[0035] The above technical solution is adopted to provide a guide groove for linearly guiding the connecting plate, so as to ensure that the connecting plate can maintain a vertical state and perform straight up and down reciprocating motion; It should be noted that a groove for guiding the connecting plate is also provided inside the mounting seat.

[0036] In summary, the present invention has the following beneficial effects: The present invention changes the disassembly and assembly mode of the two molecular sieve cartridges to from top to bottom, so that the two molecular sieve cartridges can be directly withdrawn from the mounting seat. During the withdrawal process, the air compression mechanism and the sealing component can actively separate the air inlet pipeline and the air outlet pipeline. During the insertion process, the air compression mechanism and the sealing component can actively connect and seal the air inlet pipeline and the air outlet pipeline. There is no need to disassemble and assemble the oxygen generator housing or the pipelines on the molecular sieves. Compared with the disassembly and assembly process of the traditional molecular sieve, the present invention is simpler and more convenient. Moreover, by utilizing the two molecular sieve structures of the oxygen concentrator itself and the dual-channel valve control structure (existing technology of three-way solenoid valve), the filling inside the other molecular sieve can be removed and replaced while one molecular sieve is working, which will not affect the normal operation of the oxygen concentrator. This operation is suitable for patients who need oxygen from the oxygen concentrator for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0040] Embodiment 1: refer to Figure 1-Figure 10, an oxygen concentrator for reducing infrared radiation, comprising a shell 1, a compressor cover 2 is fixedly installed at the bottom of the inner cavity of the shell 1, the inner walls of the shell 1 and the compressor cover 2 are coated with a silver layer to reduce their infrared radiation; an air compression mechanism 3 is installed inside the compressor cover 2; two sealing components 4 are fixedly connected to the bottom of the inner cavity of the shell 1, and a molecular sieve component 5 is arranged inside the sealing component 4; a linkage component 6 is installed inside the sealing component 4; two thread grooves 18 are provided on the top of the shell 1, and two limiting thread covers 19 threadedly connected to the thread grooves 18 are provided on the top of the shell 1; a controller 20 is installed on the top of the shell 1; by changing the disassembly and assembly method of the two molecular sieve cartridges 51 to from top to bottom, the two molecular sieve cartridges 51 can be directly drawn out of the mounting seat 41 During the extraction process, the air compression mechanism 3 and the sealing component 4 can actively separate the air inlet pipeline and the air outlet pipeline. During the insertion process, the air compression mechanism 3 and the sealing component 4 can actively connect and seal the air inlet pipeline and the air outlet pipeline. There is no need to disassemble the oxygen generator shell and the pipelines on the molecular sieve during the whole process. Compared with the disassembly and assembly process of the traditional molecular sieve, it is simpler and more convenient; and by using the two molecular sieve structures of the oxygen generator itself and the double-channel valve control structure (the three-way solenoid valve 34 is the existing technology), the other molecular sieve can be removed and the filler 52 inside it can be replaced during the working process of one molecular sieve, which will not affect the normal operation of the oxygen generator. This operation is suitable for patients who need oxygen from the oxygen generator for a long time.

[0041] Furthermore, the air compression mechanism 3 includes an air compressor 31, the air inlet end of the air compressor 31 is connected to an air inlet pipe 32, and the air outlet end of the air compressor 31 is connected to an air outlet pipe 33; one end of the air outlet pipe 33 is connected to a three-way solenoid valve 34, and the two ends of the three-way solenoid valve 34 are respectively connected to a first inlet pipe 35 and a second inlet pipe 36; one end of the first inlet pipe 35 and the second inlet pipe 36 are both connected to a telescopic pipe 37, and one end of the telescopic pipe 37 is provided with a driving assembly 38; through the setting of the air compression mechanism 3, it is used to compress the air and input the air into the interior of the molecular sieve cylinder 51. Specifically, the air compressor 31 is started to generate suction, and the outside air is sucked into the air compressor 31 through the air inlet pipe 32, the compressor filter 16, and the air filter 17 for compression. The compressed gas is input into the three-way solenoid valve 34 through the air outlet pipe 33. The three-way solenoid valve 34 has two channels that can flow and be closed separately. The air can flow separately to allow the air to enter the first inlet pipe 35 and the telescopic tube 37, the movable tube 381, the connecting seat 42, the filter seat 57, and the molecular sieve cartridge 51 connected to the first inlet pipe 35; the air can also flow separately to allow the air to enter the second inlet pipe 36 and the telescopic tube 37, the movable tube 381, the connecting seat 42, the filter seat 57, and the molecular sieve cartridge 51 connected to the second inlet pipe 36. The two flow channels inside the three-way solenoid valve 34 are respectively connected to the second inlet pipe 36 and the telescopic pipe 37. The three-way solenoid valve 34 can independently control the flow of one flow channel and the closure of another flow channel, which is the existing technology and will not be elaborated here. The air compressor 31 is driven by PWM, and the model of the air compressor 31 is ZR1-02-01.

[0042] Further, the drive assembly 38 includes a movable tube 381, one end of which is connected to the telescopic tube 37, and the lower surface of the movable tube 381 is fixedly connected with a tooth plate 1 382, ​​and the tooth plate 1 382 is meshed with a gear 383, and the gear 383 is meshed with a tooth plate 2 384; through the setting of the drive assembly 38, it is used to drive the connection seat 42 and the molecular sieve cylinder 51 to contact and form a seal through the force of the molecular sieve cylinder 51 pressing down. Specifically, when the molecular sieve cylinder 51 presses down to push the connecting plate 61 and the tooth plate 2 384 to descend, the tooth plate 2 384 will drive the gear 383 meshed therewith to rotate clockwise, and the gear 383 rotates clockwise to drive the tooth plate 1 382 meshed therewith to drive the movable tube 381 and the connection seat 42 to approach the molecular sieve cylinder 51. When the bottom of the connecting plate 61 is completely in contact with the bottom of the inner cavity of the mounting seat 41, the silicone sealing sleeve 45 will be set with the filter seat 57, and the silicone sealing sleeve 45 will also contact the surface of the molecular sieve cylinder 51 to form a seal. At this time, the gas inputted by the movable tube 381 can enter the interior of the molecular sieve cylinder 51 through the silicone sealing sleeve 45, the filter seat 57, and the filter screen 58. The gas inside the molecular sieve cylinder 51 can only pass downward through the filler 52, the second sealing joint 56, the sealing groove 64, the first sealing joint 44, and the delivery pipe 43 because the top of the molecular sieve cylinder 51 is sealed by the threaded cover plate 55. When the molecular sieve cylinder 51 is pulled out, the connecting plate 61 rebounds and moves upward under the action of the second spring 62. The connecting plate 61 will drive the second tooth plate 384 upward, and the second tooth plate 384 will drive the gear 383 meshing therewith to rotate counterclockwise. The gear 383 will drive the first tooth plate 382 to drive the movable tube 381 and the connecting seat 42 to move outward, so that the connecting seat 42 and the molecular sieve cylinder 51 are separated.

[0043] It should be noted that the silicone sealing sleeve 45 is made of rubber and has toughness. When the silicone sealing sleeve 45 contacts the filter seat 57, the filter seat 57 can force the silicone sealing sleeve 45 to deform. When the center points of the filter seat 57 and the silicone sealing sleeve 45 correspond, the filter seat 57 will not contact the silicone sealing sleeve 45, and the silicone sealing sleeve 45 will deform and recover and contact the surface of the molecular sieve cylinder 51 to form a seal. Secondly, the telescopic tube 37 can be telescopic. When the connecting seat 42 moves toward the molecular sieve cylinder 51, the telescopic tube 37 will extend in length. When the connecting seat 42 and the molecular sieve cylinder 51 are away from each other, the telescopic tube 37 will fold and retract. The telescopic tube 37 is specifically a telescopic bellows.

[0044] Furthermore, the sealing assembly 4 includes a mounting seat 41, a connecting seat 42 is provided inside the mounting seat 41, the connecting seat 42 is communicated with the movable tube 381, and a silicone sealing sleeve 45 is fixedly sleeved inside the connecting seat 42; the side of the mounting seat 41 close to the gear 383 is installed with the gear 383 through a bracket; the outer side of the mounting seat 41 is provided with a guide groove sleeved with the movable tube 381 and the tooth plate 382; a delivery pipe 43 is embedded in the bottom of the inner cavity of the mounting seat 41, one end of the delivery pipe 43 passes through the outer side of the mounting seat 41, and the other end of the delivery pipe 43 is communicated with a sealing joint 44; through the setting of the sealing assembly 4, the silicone seal The sealing sleeve 45 is used to contact the surface of the molecular sieve cylinder 51 and to set the filter seat 57 inside. The contact between the silicone sealing sleeve 45 and the molecular sieve cylinder 51 will form a seal, and the silicone sealing sleeve 45 will set the filter seat 57 to form a seal, so that the gas in the movable tube 381 can enter the interior of the molecular sieve cylinder 51 through the filter seat 57; the silicone sealing sleeve 45 is set inside the connecting seat 42, and the silicone sealing sleeve 45 is used to contact the surface of the molecular sieve cylinder 51 and play a sealing role; the sealing joint 44 is used to form a connection with the bottom of the sealing groove 64 and seal it, and the delivery pipe 43 is used to transport oxygen after the nitrogen is intercepted by the filler 52.

[0045] Furthermore, the molecular sieve assembly 5 comprises a molecular sieve cartridge 51, the interior of the molecular sieve cartridge 51 is filled with a filler 52, a pressure plate 53 is slidably connected to the interior of the molecular sieve cartridge 51, a spring 54 is provided on the top of the pressure plate 53, a threaded cover plate 55 threadedly connected to the molecular sieve cartridge 51 is provided on the top of the spring 54, and a sealing joint 56 is connected to the bottom of the molecular sieve cartridge 51; a filter seat 57 is threadedly connected to the surface of the molecular sieve cartridge 51, and a filter screen 58 is fixedly sleeved inside the filter seat 57; through the arrangement of the molecular sieve assembly 5, it is used to intercept compressed gas Nitrogen in the body; after the filler 52 is filled into the interior of the molecular sieve cylinder 51, the pressure plate 53 is placed into the interior of the molecular sieve cylinder 51, the spring 54 is placed on the top of the pressure plate 53, the threaded cover plate 55 presses down the spring 54, and the threaded cover plate 55 and the molecular sieve cylinder 51 are threadedly connected. Since the spring 54 is compressed when it is pressed down to generate a rebound force, and the threaded cover plate 55 and the mounting seat 41 are threadedly connected, the rebound force of the spring 54 cannot act upward but can only act downward. At this time, the rebound force of the spring 54 will push the pressure plate 53 down to compact the filler 52.

[0051] Working principle: When in use, the oxygen supply pipe for oxygen inhalation is connected to the trachea connector 15; The air compressor 31 is started, and air is sucked in through the air inlet pipe 32, the compressor filter 16, and the air filter 17; The air is first filtered by the air filter 17 and then filtered by the compressor filter 16, and enters the air compressor 31 through the air inlet pipe 32 for compression. The compressed air is discharged into the three-way solenoid valve 34 through the air outlet pipe 33; one of the two flow channels inside the three-way solenoid valve 34 is opened for circulation, such as the air enters the first inlet pipe 35, the telescopic pipe 37 connected to the first inlet pipe 35, and the movable pipe 381 through the three-way solenoid valve 34, and then enters the filter seat 57 through the movable pipe 381, passes through the filter screen 58 and enters the molecular sieve cylinder 51. The air is in the molecular sieve The air inside the cylinder 51 flows downward, and the nitrogen is trapped by the filler 52, and the oxygen is discharged through the sealing joint 2 56, the sealing groove 64, the sealing joint 1 44, and the delivery pipe 43. The oxygen discharged from the delivery pipe 43 will enter the gas storage bin 13, and then enter the flow monitoring sensor 11 through the connecting pipe 12, and the flow rate is monitored by the flow monitoring sensor 11. After that, the oxygen enters the oxygen purity monitor 8 through the connecting pipe 9, and the oxygen concentration is monitored by the oxygen purity monitor 8. Then, the oxygen drops into the outlet pipe 10 and is discharged into the oxygen supply pipe through the trachea joint 15 for the patient to inhale.

[0052] During the operation of the oxygen generator, since only one of the fillers 52 in the molecular sieve cartridge 51 is in working state and the other molecular sieve cartridge 51 is not working, when the filler 52 needs to be replaced; The flow channel of the gas inside and the second inlet pipe 36 is in a flow state through the three-way solenoid valve 34, and the other flow channel connected to the first inlet pipe 35 is closed. At this time, the second inlet pipe 36 and its connected telescopic pipe 37, movable pipe 381 and the filler 52 inside the corresponding molecular sieve cylinder 51 are in a working state; the other first inlet pipe 35 and the filler 52 inside the corresponding molecular sieve cylinder 51 are not working.

[0053] The process of removing the inoperative molecular sieve cartridge 51 is as follows: First, the limiting threaded cover 19 on the top of the molecular sieve cartridge 51 is rotated to separate from the housing 1, and the molecular sieve cartridge 51 at the bottom of the limiting threaded cover 19 loses the limiting limit of the limiting threaded cover 19, and the spring 2 62 rebounds to pull the connecting plate 61 to push the filler 52 and the molecular sieve cartridge 51 up. During the rising process, the connecting plate 61 will also drive the tooth plate 2 384 to mesh with the gear 383, so that the gear 383 rotates counterclockwise. The counterclockwise rotation of the gear 383 will drive the tooth plate 1 382 to drive the movable tube 381 and the connecting seat 42 to move to the left (see Fig. 9 ); The connecting seat 42 will be separated from the molecular sieve cartridge 51 , and the movable tube 381 will exert force on the telescopic tube 37 to fold and retract the telescopic tube 37 .

[0054] Then, the molecular sieve cartridge 51 can be directly pulled out, the threaded cover plate 55 and the molecular sieve cartridge 51 can be separated, the pressing plate 53 can be taken out, the filler 52 can be dumped out and replaced with a new filler 52, and then the pressing plate 53, the spring 1 54, and the threaded cover plate 55 can be installed in sequence; Then insert the molecular sieve cartridge 51 into the mounting seat 41. First, the slider 22 and the slide groove 21 must be aligned. Then, during the insertion of the molecular sieve cartridge 51 into the mounting seat 41, the filter seat 57 will pass through the through groove 24. When the bottom of the molecular sieve cartridge 51 contacts the connecting plate 61, the sealing joint 2 56 at the bottom of the molecular sieve cartridge 51 will be inserted into the sealing groove 64 to form a connection and a seal; Then, press down the molecular sieve cylinder 51 to make the top of the molecular sieve cylinder 51 flush with the top of the shell 1, and thread the limiting thread cover 19 and the thread groove 18 together. The inner diameter of the limiting thread cover 19 is larger than the length of the top of the thread cover plate 55, and the bottom of the limiting thread cover 19 will contact the top of the thread cover plate 55. By rotating the limiting thread cover 19, the thread cover plate 55 and the molecular sieve cylinder 51 can be pressed tightly, thereby limiting the position of the molecular sieve cylinder 51.

[0055] By tightening the limiting threaded cover 19, the molecular sieve cartridge 51 can be completely inserted into the mounting seat 41, and the sealing groove 64 inside the connecting plate 61 and the sealing joint 44 can be sealed and connected.

[0056] When the molecular sieve cartridge 51 is inserted into the mounting seat 41, the bottom of the molecular sieve cartridge 51 contacts the top of the connecting plate 61. As the molecular sieve cartridge 51 pushes the connecting plate 61 downward, the connecting plate 61 pulls the spring 2 62 to extend and generate a rebound force. At the same time, the connecting plate 61 will also drive the tooth plate 2 384 upward, and the tooth plate 2 384 downward can drive the gear 383 engaged therewith to rotate clockwise, and the gear 383 rotates clockwise to drive the tooth plate 1 382 engaged therewith to drive the movable tube 381, the connecting seat 42, and the silicone sealing sleeve 45 to move toward the molecular sieve cylinder 51; at the same time, it will also pull the telescopic tube 37 out.

[0057] When the molecular sieve cartridge 51 cannot move downward any further, that is, the bottom of the connecting plate 61 is completely in contact with the bottom of the inner cavity of the mounting seat 41, the filter seat 57 will correspond to one end of the movable tube 381 (see Fig.10 ), and the inner wall of the silicone sealing sleeve 45 will completely contact with the molecular sieve cartridge 51 to form a seal, and the filter seat 57 will be located inside the silicone sealing sleeve 45 and wrapped and sealed.

[0058] Then, the flow path of the circulating air is changed through the three-way solenoid valve 34 to make the corresponding molecular sieve cartridge 51 and filler 52 connected to the first inlet pipe 35 work; the circulation of the second inlet pipe 36 is closed, and the molecular sieve cartridge 51 and filler 52 corresponding to the second inlet pipe 36 can be replaced according to the above operation.
