[0005] Furthermore, the drainage fan is located inside the cylindrical rod, the auxiliary fan is located at the outer end of the cylindrical rod, and the end of the rotating rod passes through the bracket and extends to the outer end of the bracket.

[0006] Furthermore, the surface of the adapter helical gear meshes with the inner wall of the helical gear, the end of the rotating rod away from the power device passes through the mounting frame and extends to the inside of the circular tube, and the drainage fan is located at the end of the circular tube close to the oxygen concentrator.

[0007] Furthermore, the air pushing component includes a fixed rod, the end of the fixed rod is fixedly connected to the inner wall of the circular tube, the ends of the fixed rod and the rotating rod that are close to each other are respectively fixedly connected to a turntable, the ends of the two turntables that are close to each other are fixedly connected to an axle rod, a pull plate is sleeved on the surface of the axle rod, and the end of the pull plate away from the axle rod is rotatably connected to the air pushing disk, and a circular hole is opened on the surface of the air pushing disk.

[0008] Furthermore, the shaft is arranged at one end of the turntable away from the air pushing disk, the air pushing disk is located inside the circular tube, and the two turntables are symmetrically arranged with the pulling plate as the center.

[0009] Furthermore, the air pushing disk is located at one end of the circular tube close to the mounting tube, and there are four circular holes, which are arranged in a circle with the air pushing disk as the center.

[0010] Furthermore, the sealing component includes an elastic rod, the end of the elastic rod is fixedly connected to the surface of the thrust disk, the end of the elastic rod away from the thrust disk is fixedly connected to a linkage frame, the end of the linkage frame away from the elastic rod is fixedly connected to a sealing plate, the surface of the linkage frame is fixedly connected to a synchronization plate, the end of the synchronization plate away from the linkage frame is fixedly connected to a reinforcement ring, and the surface of the reinforcement ring is fixedly connected to a rubber pad.

[0011] Furthermore, the elastic rod is located at an end of the air pushing disk away from the pulling plate, and the surface of the sealing plate is adapted to the inner wall of the circular hole.

[0012] Furthermore, there are four sealing plates, which are arranged in a circle with the elastic rod as the center circumference, and the positions of the sealing plates correspond to the circular holes, and the surface of the rubber pad contacts the inner wall of the mounting tube.

[0013] The present invention has the following beneficial effects: After the oxygen concentrator of the present invention begins operation, the sealing cover on the surface of the mounting tube is removed to separate the rubber block from the surface of the mounting tube. The oxygen supply tube is then plugged into the surface of the mounting tube to connect the connection. Oxygen in the oxygen concentrator is then delivered to the patient's nasal cavity through the oxygen supply tube. A sensor is provided on the surface of the mounting tube to detect the oxygen flow rate inside the mounting tube. When the sensor senses a decrease in the patient's respiratory rate, the power unit is activated to rotate the rotating rod. The rotating rod rotates, which in turn drives the helical gear to rotate. The matching helical gear, through engagement with the helical gear, drives the rotating rod to rotate inside the bracket. The rotating rod rotates, which in turn drives the drainage fan to rotate inside the cylindrical rod. The rotation of the drainage fan transfers oxygen from the circular tube to the interior of the mounting tube. The drainage fan and the auxiliary fan cooperate to transport oxygen, so that oxygen can be delivered to the patient's nasal cavity by the drainage fan. The patient can now absorb a large amount of oxygen through slight breathing, reducing the pressure required for the patient to inhale oxygen. The sensor adjusts the speed of the power unit by sensing the patient's respiratory rate, so that the drainage fan can adjust the oxygen flow rate inside the circular tube.

[0014] When the rotating rod of the present invention rotates, it will drive the turntable to rotate. When the turntable rotates, the pull plate is rotated by pulling the shaft. Because the shaft is eccentrically arranged, the end of the pull plate away from the shaft will move when it rotates. When the pull plate moves, it will pull the air push plate to move back and forth. When the air push plate moves to the inside of the installation tube, it will push the oxygen to flow inside the oxygen supply tube, so that the oxygen generated by the oxygen concentrator can quickly flow to the patient's nasal cavity for the patient to absorb, thereby increasing the flow speed of oxygen and preventing the patient from not absorbing oxygen due to slight breathing.

[0015] When the push disc moves toward the outer end of the mounting tube, the rubber pad uses friction to limit the sealing plate, so that the push disc can be separated from the inner wall of the sealing plate, so that the oxygen inside the circular tube enters the interior of the mounting tube for transmission.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The drainage component 9 includes a mounting frame 20, the end of the mounting frame 20 is fixedly connected to the surface of the circular tube 4, and the inner wall of the mounting frame 20 is fixedly connected to a power device 21. The oxygen flow rate inside the mounting tube 5 is detected by the sensor 6. When the sensor 6 senses that the patient's respiratory rate has decreased, the power device 21 is started to drive the rotating rod 27 to rotate. When the rotating rod 27 rotates, the bevel gear 26 is rotated. The output end of the power device 21 is fixedly connected to the rotating rod 27, and the surface of the rotating rod 27 is fixedly connected to the bevel gear 26. The inner wall of the circular tube 4 is fixedly connected to the bracket 25, and the inner wall of the bracket 25 is rotatably connected to the rotating rod 29. The end of the rotating rod 29 It is fixedly connected with an adapting bevel gear 28, and the end of the rotating rod 29 away from the adapting bevel gear 28 is fixedly connected with the drainage fan 24. The adapting bevel gear 28 drives the rotating rod 29 to rotate inside the bracket 25 through the engagement with the bevel gear 26. When rotating, the rotating rod 29 drives the drainage fan 24 to rotate inside the cylindrical rod 22. The oxygen inside the circular tube 4 is transmitted to the inside of the mounting tube 5 through the rotation of the drainage fan 24. The end of the drainage fan 24 away from the rotating rod 29 is fixedly connected with the auxiliary fan 23, and the inner wall of the circular tube 4 is fixedly connected with the cylindrical rod 22. The inside of the circular tube 4 is provided with an air pushing component 10, and the inside of the mounting tube 5 is provided with a sealing component 11.

[0022] The drainage fan 24 is located inside the cylindrical rod 22. Oxygen is transported through the cooperation of the drainage fan 24 and the auxiliary fan 23, so that oxygen can be transmitted to the patient's nasal cavity by the drainage fan 24. At this time, the patient can absorb a large amount of oxygen through slight breathing. The auxiliary fan 23 is located at the outer end of the cylindrical rod 22, and the end of the rotating rod 29 passes through the bracket 25 and extends to the outer end of the bracket 25.

[0023] The surface of the adapter helical gear 28 meshes with the inner wall of the helical gear 26 . The end of the rotating rod 27 away from the power device 21 passes through the mounting frame 20 and extends into the interior of the circular tube 4 . The exhaust fan 24 is located at the end of the circular tube 4 close to the oxygen concentrator 1 .

[0024] The pushing component 10 includes a fixed rod 30, the end of the fixed rod 30 is fixedly connected to the inner wall of the circular tube 4, and the fixed rod 30 and the rotating rod 27 are respectively fixedly connected to a turntable 31 at one end close to each other. The rotating rod 27 will drive the turntable 31 to rotate when it rotates, and the turntable 31 will pull the pull plate 34 to rotate through the shaft rod 33 when it rotates. Because the shaft rod 33 is eccentrically arranged, the ends of the two turntables 31 close to each other are fixedly connected to the shaft rod 33, and the surface of the shaft rod 33 is sleeved with a pull plate 34. When the pull plate 34 rotates, the end away from the shaft rod 33 will move, and the pull plate 34 will pull the pushing plate 32 back and forth when it moves. The end of the pull plate 34 away from the shaft rod 33 is rotatably connected to the pushing plate 32, and a circular hole 36 is provided on the surface of the pushing plate 32.

[0025] The shaft 33 is set at one end of the turntable 31 away from the air pushing disk 32. When the air pushing disk 32 moves to the inside of the mounting tube 5, it will push the oxygen to flow inside the oxygen supply tube, so that the oxygen generated by the oxygen concentrator 1 can quickly flow to the patient's nasal cavity for the patient to absorb. The air pushing disk 32 is located inside the circular tube 4, and the two turntables 31 are symmetrically arranged with the pull plate 34 as the center.

[0026] The air pushing disk 32 is located at one end of the circular tube 4 close to the mounting tube 5 . There are four circular holes 36 , which are arranged around a circle with the air pushing disk 32 as the center.

[0027] The sealing component 11 includes an elastic rod 40, the end of the elastic rod 40 is fixedly connected to the surface of the push disk 32, the end of the elastic rod 40 away from the push disk 32 is fixedly connected to a linkage frame 41, the surface of the rubber pad 43 contacts the inner wall of the mounting tube 5, and the reinforcement ring 42 can support the rubber pad 43, thereby improving the stability of the rubber pad 43 moving inside the mounting tube 5. The end of the linkage frame 41 away from the elastic rod 40 is fixedly connected to a sealing plate 45, and the surface of the linkage frame 41 is fixedly connected to a synchronization plate 44. The reinforcement ring 42 is connected to the synchronization plate 44, and the elastic rod 40 can limit the push disk 32 through the connection with the linkage frame 41 to prevent the push disk 32 from tilting during movement. The end of the synchronization plate 44 away from the linkage frame 41 is fixedly connected to the reinforcement ring 42, and the surface of the reinforcement ring 42 is fixedly connected to the rubber pad 43.

[0028] The elastic rod 40 is located at the end of the air pushing disk 32 away from the pull plate 34. When the air pushing disk 32 moves toward the inside of the mounting tube 5, the rubber pad 43 will limit the linkage frame 41 through the friction with the inner wall of the mounting tube 5. At this time, the air pushing disk 32 will compress the elastic rod 40 when moving and push the circular hole 36 to contact the surface of the sealing plate 45 to seal it. The surface of the sealing plate 45 is adapted to the inner wall of the circular hole 36.

[0029] There are four sealing plates 45, and the four sealing plates 45 are arranged in a circle with the elastic rod 40 as the center. When the air push plate 32 moves toward the outer end of the mounting tube 5, the rubber pad 43 uses friction to limit the sealing plate 45, so that the air push plate 32 can be separated from the inner wall of the sealing plate 45, and the position of the sealing plate 45 corresponds to the circular hole 36, and the surface of the rubber pad 43 contacts the inner wall of the mounting tube 5.

[0030] When in use, after the oxygen concentrator 1 starts working, the sealing cover 8 on the surface of the mounting tube 5 is removed, so that the rubber block 7 is separated from the surface of the mounting tube 5. At this time, the oxygen supply tube is plugged into the surface of the mounting tube 5 to connect it. At this time, the oxygen inside the oxygen concentrator 1 will be delivered to the patient's nasal cavity through the oxygen supply tube. A sensor 6 is provided on the surface of the mounting tube 5. The sensor 6 is used to detect the oxygen flow rate inside the mounting tube 5. When the sensor 6 senses that the patient's respiratory rate is reduced, the power device 21 is started to drive the rotating rod 27 to rotate. When the rotating rod 27 rotates, it drives the bevel gear 26 to rotate. The matching bevel gear 28 drives the rotating rod 29 to rotate inside the bracket 25 by meshing with the bevel gear 26. When the rotating rod 29 rotates, it drives The dynamic drainage fan 24 rotates inside the cylindrical rod 22, and the oxygen inside the circular tube 4 is transmitted to the inside of the mounting tube 5 through the rotation of the drainage fan 24. The oxygen is transported by the cooperation of the drainage fan 24 and the auxiliary fan 23, so that the oxygen can be transmitted to the patient's nasal cavity by the drainage fan 24. At this time, the patient can absorb a large amount of oxygen through slight breathing, reducing the pressure required for the patient to inhale oxygen. The sensor 6 adjusts the speed of the power device 21 by sensing the patient's breathing frequency so that the drainage fan 24 can adjust the oxygen flow rate inside the circular tube 4. The rotating rod 27 drives the turntable 31 to rotate when it rotates. When the turntable 31 rotates, the pull plate 34 is pulled by the shaft 33 to rotate. Because the shaft 33 is eccentrically set, the pull plate 34 rotates. The end away from the shaft 33 will move, and the pull plate 34 will pull the push plate 32 back and forth when it moves. When the push plate 32 moves to the inside of the mounting tube 5, it will push the oxygen to flow inside the oxygen supply tube, so that the oxygen generated by the oxygen concentrator 1 can quickly flow to the patient's nasal cavity for the patient to absorb, thereby increasing the flow rate of oxygen and preventing the patient from not being able to absorb oxygen even with a slight breath. The surface of the rubber pad 43 contacts the inner wall of the mounting tube 5, and the reinforcement ring 42 can support the rubber pad 43 to improve the stability of the rubber pad 43 moving inside the mounting tube 5. The reinforcement ring 42 is connected to the synchronization plate 44, and the elastic rod 40 can limit the push plate 32 by connecting with the linkage frame 41 to prevent the push plate 32 from moving. The tilted situation improves the stability of the air push disc 32 during operation. When the air push disc 32 moves toward the inside of the mounting tube 5, the rubber pad 43 will limit the linkage frame 41 through the friction with the inner wall of the mounting tube 5. At this time, the air push disc 32 will compress the elastic rod 40 when moving and push the circular hole 36 to contact the surface of the sealing plate 45 to seal it. At this time, the air push disc 32 cooperates with the sealing plate 45 when moving to deliver oxygen to the patient's nasal cavity. When the air push disc 32 moves toward the outer end of the mounting tube 5, the rubber pad 43 uses friction to limit the sealing plate 45, so that the air push disc 32 can be separated from the inner wall of the sealing plate 45, so that the oxygen inside the circular tube 4 enters the interior of the mounting tube 5 for transmission of oxygen.
