Description

Technical Field

[0001] The invention relates to the field of oxygen concentrators, and in particular to an oxygen humidification cup structure with a constant temperature oxygen tube. Background Art

[0002] Oxygen concentrators are widely used in homes, hospitals, sanatoriums, schools, hotels, sports venues, bars, oxygen bars, and plateau military stations. As people's awareness of health increases, the market for home oxygen concentrators has gradually emerged and has become an important health care device. As a home medical device, its market demand continues to grow with people's pursuit of a healthy life.

[0003] The oxygen humidification cup in the oxygen concentrator is an important accessory in the oxygen concentrator. Its main function is to humidify the oxygen produced by the oxygen concentrator so that the oxygen becomes moist before inhalation and reduces discomfort to the respiratory tract.

[0004] In the existing oxygen concentrator, the oxygen humidification cup is separated from the oxygen supply pipe outside the oxygen concentrator. The oxygen humidification cup returns the humidified oxygen to the pipeline inside the oxygen concentrator and outputs it from the oxygen outlet on the oxygen concentrator body. The oxygen supply pipe is installed on the oxygen outlet on the oxygen concentrator body. In this way, the humidity of the oxygen humidified by the oxygen humidification cup decreases after passing through the pipeline inside the oxygen concentrator. For example, water vapor will condense on the inner wall of the pipeline inside the oxygen concentrator, resulting in the humidity of the oxygen finally entering the oxygen supply pipe cannot be guaranteed. In addition, the temperature of the humidified oxygen is also difficult to be effectively controlled, which easily causes the user to breathe cold oxygen. The human body will feel uncomfortable after inhaling cold oxygen, which is not conducive to the human body's recovery, especially in cold winter. Summary of the invention

[0005] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide an oxygen humidification cup structure with a constant temperature oxygen tube.

[0006] According to one aspect of the present invention, there is provided an oxygen humidification cup structure with a constant temperature oxygen tube, comprising:

[0007] A cup body, wherein an air inlet and an air outlet are arranged on the top of the cup body;

[0008] An adapter, an air inlet pipe is provided at the bottom of the adapter, a connecting pipe connected to the air inlet pipe is provided at the side of the adapter, an air outlet pipe is provided on the adapter, the bottom of the air outlet pipe extends from the bottom of the adapter, a plug seat is provided at the top of the adapter, the top of the air outlet pipe is located in the plug seat, the air inlet pipe is plugged into the air inlet, the bottom of the air outlet pipe is plugged into the air outlet, and the adapter is detachably connected to the cup body; and

[0009] A constant temperature oxygen tube, one end of which is provided with a plug connector, which is plugged into a plug socket to achieve a detachable connection between the constant temperature oxygen tube and the adapter.

[0010] The oxygen humidification cup structure of the present invention is installed on the oxygen concentrator, and the connecting pipe on the adapter is connected with the oxygen outlet on the oxygen concentrator. When the oxygen concentrator is working, the oxygen produced by the oxygen concentrator enters the cup body through the connecting pipe and the air inlet pipe. After being moistened by the water in the cup body, the oxygen is discharged to the nasal plug oxygen inhalation tube or the oxygen inhalation nasal mask through the air outlet, the air outlet pipe, the socket, and the constant temperature oxygen tube in sequence for the user to breathe. The water content of the oxygen discharged from the constant temperature oxygen tube increases, thereby realizing the humidification of the oxygen. In the oxygen humidification cup structure of the present invention, the oxygen humidified by the cup body is directly output to the constant temperature oxygen tube, and the humidified oxygen does not need to be output Returning to the pipeline inside the oxygen concentrator, the water vapor carried by the humidified oxygen can be prevented from condensing in the pipeline inside the oxygen concentrator, ensuring the humidity of the oxygen entering the constant temperature oxygen tube. At the same time, the constant temperature oxygen tube can ensure that the temperature of the output oxygen is maintained in an appropriate range, so that the user can breathe comfortable oxygen. In addition, the constant temperature oxygen tube and the adapter are detachably connected, and the adapter and the cup body are detachably connected. The oxygen humidification cup structure can be transported and stored as an integral structure. At the same time, it is also convenient to clean the constant temperature oxygen tube, the adapter, and the cup body separately to ensure hygiene and safety.

[0011] Furthermore, it also includes a cap body and a pressure relief block. The top of the cup body is provided with a convex ring and a pressure relief hole. The pressure relief hole is located at the bottom of the space enclosed by the convex ring. The side wall of the convex ring is provided with a notch. The bottom of the cap body is provided with a convex column. The pressure relief block is provided with a concave cavity. The bottom of the convex column is inserted in the cavity. The cap body cover is arranged on the top of the convex ring.

[0012] When the air pressure in the cup is less than or equal to the set value, the pressure relief block blocks the pressure relief hole.

[0013] When the air pressure in the cup body is greater than a set value, the pressure relief block is separated from the pressure relief hole and the gas in the cup body can be released through the notch on the side wall of the convex ring.

[0014] Therefore, since the bottom of the boss is inserted in the cavity, the pressure relief block has an up and down floating space at the bottom of the boss. When the pressure of the oxygen in the cup body is greater than the set value, the oxygen in the cup body will push the pressure relief block upward through the pressure relief hole to separate the pressure relief block from the pressure relief hole. At this time, part of the oxygen will leak out through the notch on the side wall of the convex ring. When the air pressure in the cup body is less than or equal to the set value, the pressure relief block will block the pressure relief hole downward under the action of its gravity, thereby ensuring that the pressure of the oxygen in the cup body is maintained within a reasonable range. The presence of the boss on the cap body can ensure that the pressure relief block is always located directly above the pressure relief hole to prevent the pressure relief block from being displaced during the up and down floating process.

[0015] Furthermore, a receiving cavity is provided at the bottom of the adapter, and the pressure relief cap is received in the receiving cavity. Therefore, it can be ensured that the cap body is always covered on the top of the convex ring, and the bottom of the convex column on the cap body can always be inserted into the cavity on the pressure relief block, so that the pressure relief block is always located directly above the pressure relief hole.

[0016] Furthermore, the cover body is provided with a bendable belt body on the side of the cover body, the end of the belt body is provided on the socket, and the cover body can cover the top of the socket. Therefore, when the constant temperature oxygen tube is removed from the adapter, the belt body can be bent to cover the top of the socket, so as to prevent foreign matter or dust from entering the socket, thereby ensuring hygiene and safety.

[0017] Furthermore, it also includes a sealing ring, the bottom of the cup body is open, the bottom of the cup body is provided with a heat-conducting cover, the bottom of the cup body is provided with a circle of convex edges extending outward, the heat-conducting cover is provided with a circle of inner grooves facing the center of the heat-conducting cover, the end face of the sealing ring is provided with multiple circles of convex ribs, the sealing ring is arranged in the inner groove, the convex edge at the bottom of the cup body is inserted into the inner groove, and the sealing ring is located between the convex edge and the inner bottom of the inner groove. Therefore, a heating component can be provided on the oxygen concentrator, and after the oxygen humidification cup structure is installed on the oxygen concentrator, the heating component can heat the heat-conducting cover, and the heat-generating heat-conducting cover can heat the water in the cup body. The controller of the oxygen concentrator can maintain the temperature of the water in the cup body within a certain range by controlling the heating component, ensuring that the humidified oxygen maintains a certain temperature, so that the user can breathe comfortable oxygen, and the convex ribs on the sealing ring can further ensure the sealing of the bottom of the cup body.

[0018] Furthermore, the two sides of the plug connector are provided with obliquely arranged plug-ins, the plug connectors are provided with buckles, the inner wall of the socket is provided with two slots adapted to the plug-ins, and the slots are provided with slots adapted to the buckles. Therefore, the plug connector is respectively connected to the slots on the socket through the buckles on the two plug-ins, ensuring that the plug connector is firmly connected to the socket and will not be easily dislodged. When the plug connector needs to be removed from the socket on the adapter, the two plug-ins are held and pressed inwardly, the buckles on the plug connector are dislodged from the slots, and then the plug connector is pulled out. The installation and removal of the plug connector on the thermostatic oxygen tube and the socket on the adapter are very convenient, and the obliquely arranged plug-ins are convenient for the plug connector to be connected to the socket, and can ensure that the buckles on the plug connector are connected outwardly to the slots on the slot and will not be easily dislodged.

[0019] Furthermore, the constant temperature oxygen tube includes a pipeline, a heating wire and a temperature sensor. One end of the pipeline is arranged on the plug connector, the heating wire is arranged on the periphery of the pipeline and is arranged in a spiral shape, the plug connector is provided with a connecting terminal, the heating wire is connected to the connecting terminal, and the temperature sensor is arranged on the other end of the pipeline to detect the temperature of the oxygen output from the pipeline. The socket is provided with a terminal socket adapted to the connecting terminal, and the side of the adapter is provided with a terminal socket connected to the terminal socket. Therefore, since the periphery of the pipeline is provided with a spirally arranged heating wire, the heating wire can evenly heat the oxygen in the pipeline, and the temperature sensor can detect the temperature of the oxygen output from the pipeline in real time. When the temperature sensor detects that the temperature of the oxygen is higher than the set value, the heating wire is controlled to stop working. When the temperature sensor detects that the temperature of the oxygen is lower than the set value, the heating wire is controlled to start working. For example, the heating wire can be controlled to work or stop working by the controller of the oxygen concentrator, so that the temperature of the oxygen output from the pipeline is maintained within a suitable range, so that the user can breathe comfortable oxygen. Moreover, since the heating wire is spirally wound around the periphery of the pipeline, it will not affect the size of the entire oxygen concentrator and will not affect the portability of the oxygen concentrator.

[0020] Furthermore, the constant temperature oxygen tube also includes a connector, which is arranged on the other end of the pipeline, a groove is arranged on the outer wall of the connector, a plug-in through hole is arranged on the peripheral wall of the connector, the plug-in through hole is located in the groove, and the temperature sensor is arranged in the connector and the side of the temperature sensor is clamped in the plug-in through hole. Therefore, the constant temperature oxygen tube can be connected to a nasal plug oxygen inhalation tube or an oxygen inhalation nasal mask through the connector, and the temperature sensor installed in the connector can accurately detect the temperature of oxygen in the pipeline, and the side of the temperature sensor is clamped in the plug-in through hole to ensure that the temperature sensor is firmly installed and will not fall off due to bending or pulling of the pipeline to affect the detection of oxygen. In addition, the presence of the groove on the outer wall of the connector facilitates the installation and disassembly of the temperature sensor.

[0021] Furthermore, an anti-scalding tube is provided on the heating wire, the wiring harness of the temperature sensor is accommodated in the anti-scalding tube and connected to the connection terminal, a spiral groove is provided on the outer circumference of the pipeline, and the anti-scalding tube is spirally accommodated in the spiral groove. Therefore, the anti-scalding tube can ensure that the working heating wire will not burn the user, and can also wrap the wiring harness of the temperature sensor so that the wiring harness of the temperature sensor and the pipeline form a whole, and the bending or pulling of the pipeline will not cause the wiring harness of the temperature sensor to be poorly connected and affect the operation of the temperature sensor. The anti-scalding tube arranged in a spiral shape is accommodated in the spiral groove on the outer circumference of the pipeline, so that the heating wire and the anti-scalding tube will not slide randomly on the pipeline, ensuring that the heating wire arranged in a spiral shape can always be evenly distributed on the pipeline, ensuring the uniformity and stability of the heating of oxygen in the pipeline.

[0022] Furthermore, a plug tube connected to the pipeline is provided at the end of the plug connector.

[0023] When the plug connector is plugged into the plug socket, the plug tube is plugged into the air outlet pipe.

[0024] Therefore, in this case, when the constant temperature oxygen tube is installed on the adapter, the oxygen in the cup body can be discharged directly into the plug-in tube through the outlet pipe to avoid oxygen leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The top of the cup body 1 is provided with an air inlet 11 and an air outlet 12. Specifically, in this embodiment, refer to Figures 1 to 4 The top of the cup body 1 is open, and a cup cover 101 is installed on the top of the cup body 1. The cup cover 101 is threadedly connected to the cup body 1. The air inlet 11 and the air outlet 12 are arranged on the cup cover 101. The air inlet 11, the air outlet 12 and the cup cover 101 can be integrally formed. Water can be added to the cup body 1 by unscrewing the cup cover 101 from the cup body 1. The detachable connection between the cup cover 101 and the cup body 1 also facilitates cleaning the interior of the cup body 1.

[0035] The adapter 2 is installed on the cup body 1. Specifically, the adapter 2 is installed on the cup cover 101 of the cup body 1. Figure 4 An air inlet pipe 21 is installed at the bottom of the adapter 2, and a connecting pipe 22 is installed at the side of the adapter 2. The air inlet pipe 21 and the connecting pipe 22 are both inserted into the adapter 2. The air inlet pipe 21 and the connecting pipe 22 are connected and arranged at 90 degrees. An air outlet pipe 23 is installed on the adapter 2. The air outlet pipe 23 is longitudinally inserted into the adapter 2, and the bottom of the air outlet pipe 23 extends out from the bottom of the adapter 2. Figures 1 to 4The top of the air outlet pipe 23 extends out from the top of the adapter 2, and a socket 24 is installed on the top of the adapter 2. The socket 24 can be snapped into a groove on the top of the adapter 2 and locked by screws. The top of the air outlet pipe 23 is located in the socket 24, the air inlet pipe 21 is plugged into the air inlet 11, and the bottom of the air outlet pipe 23 is plugged into the air outlet 12. Sealing rings (not shown) are installed on the air inlet pipe 21 and the air outlet pipe 23 to ensure the sealing of the connection. The adapter 2 is detachably connected to the cup body 1, and the adapter 2 It can be directly removed from the cup cover 101 of the cup body 1, so that it is convenient to clean the adapter 2 and the cup body 1 separately to ensure hygiene and safety; when the oxygen humidification cup structure is installed on the oxygen generator, the connecting pipe 22 on the adapter 2 is connected to the oxygen outlet on the oxygen generator. When the oxygen generator is working, the oxygen produced by the oxygen generator enters the cup body 1 through the connecting pipe 22, the air inlet pipe 21, and the air inlet 11. After being moistened by the water in the cup body 1, the oxygen is discharged to the socket 24 through the air outlet 12 and the air outlet pipe 23 in turn.

[0036] The top of the cup body 1 is provided with a convex ring 13 and a pressure relief hole 14. Figures 1 to 4The convex ring 13 and the pressure relief hole 14 are arranged on the cup cover 101 of the cup body 1. The convex ring 13, the pressure relief hole 14 and the cup cover 101 can be integrally formed. The top of the cup cover 101 is integrally formed with a convex ring 13 protruding upward. The cup cover 101 is formed with a pressure relief hole 14. The pressure relief hole 14 is located at the bottom of the space enclosed by the convex ring 13. The side wall of the convex ring 13 is formed with a notch 131 near the top of the convex ring 13. The top of the notch 131 is open. The bottom of the cap body 4 is formed with a convex column 41, and the pressure relief block 5 is formed with an inwardly concave cavity 51, the cross section of the cavity 51 can be circular, the inner diameter of the cavity 51 is larger than the diameter of the convex column 41, the bottom of the convex column 41 is inserted into the cavity 51, the cap body 4 is covered on the top of the convex ring 13, in order to ensure that the cap body 4 can be firmly covered on the top of the convex ring 13, the top of the convex ring 13 is formed with a circle of bosses close to the inner wall, and the inner wall of the cap body 4 is formed with a circle of steps adapted to the bosses on the convex ring 13. When the cap body 4 is covered on the top of the convex ring 13, the convex on the convex ring 13 The platform is inserted in the cap body 4 and presses upward on the step on the inner wall of the cap body 4; because the bottom of the convex column 41 is inserted in the cavity 51, the pressure relief block 5 has an upper and lower floating space at the bottom of the convex column 41. When the air pressure in the cup body 1 is less than or equal to the set value, the pressure relief block 5 blocks the pressure relief hole 14 downward under the action of its own gravity. At this time, the bottom of the convex column 41 does not contact the inner bottom of the cavity 51, providing floating space for the pressure relief block 5 to float upward. When the air pressure in the cup body 1 is greater than the set value, the pressure relief block 5 in the cup body 1 Oxygen will push up the pressure relief block 5 through the pressure relief hole 14 to separate the pressure relief block 5 from the pressure relief hole 14. At this time, part of the oxygen will leak out through the notch 131 on the side wall of the convex ring 13, thereby ensuring that the pressure of the oxygen in the cup body 1 is maintained within a reasonable range. The presence of the convex column 41 on the cap body 4 can ensure that the pressure relief block 5 is always located directly above the pressure relief hole 14 to prevent the pressure relief block 5 from being displaced during the up and down floating process. The material and quality of the pressure relief block 5 can be adjusted accordingly according to the size of the above-mentioned set value.

[0037] See also Figure 4 A receiving cavity 25 is formed at the bottom of the adapter 2, and the cap body 4 is received in the receiving cavity 25. In this way, it can be ensured that the cap body 4 is always covered on the top of the convex ring 13, and that the bottom of the convex column 41 on the cap body 4 can always be inserted into the cavity 51 on the pressure relief block 5, so as to ensure that the pressure relief block 5 is always located directly above the pressure relief hole 14. In addition, since the air inlet pipe 21 is directly inserted into the air inlet 11, the air outlet pipe 23 is directly inserted into the air outlet 12, and the cap body 4 is received in the receiving cavity 25, the adapter 2 can be directly pulled off from the cup cover 101 of the cup body 1 to realize the detachable connection between the adapter 2 and the cup body 1. In this way, it is convenient to clean the adapter 2, the cap body 4, the cup body 1 and the cup cover 101 separately to ensure hygiene and safety.

[0038] See also Figure 3 and Figure 4The side of the cover body 6 is integrally formed with a bendable belt body 61 ( Figure 1 and Figure 2 (not shown), the free end of the belt body 61 can be fixed to the bottom of the side wall of the socket 24, and the cover body 6 can cover the top of the socket 24. For example, a convex portion is formed on the bottom of the cover body 6. When the cover body 6 covers the top of the socket 24, the convex portion at the bottom of the cover body 6 is interference fit in the socket 24. The cover body 6 can be made of rubber material. In this way, when the constant temperature oxygen tube 3 is removed from the adapter 2, the belt body 61 can be bent to cover the cover body 6 on the top of the socket 24 to prevent foreign matter or dust from entering the socket 24, thereby ensuring hygiene and safety.

[0039] See also Figure 3 and Figure 4 The bottom of the cup body 1 is open, and a heat-conducting cover 15 is installed at the bottom of the cup body 1. Specifically, a convex edge 16 extending outward is formed at the bottom of the cup body 1, and a circle of inner groove 151 facing the center of the heat-conducting cover 15 is formed on the heat-conducting cover 15. The sealing ring 7 is accommodated in the inner groove 151. The convex edge 16 at the bottom of the cup body 1 is inserted into the inner groove 151 and the sealing ring 7 is located between the convex edge 16 and the inner bottom of the inner groove 151. A heating component can be provided on the oxygen concentrator. After the cup body 1 is installed on the oxygen concentrator, the heating component can heat the heat-conducting cover 15 at the bottom of the cup body 1. The heated heat-conducting cover 15 can heat the water in the cup body 1. The controller of the oxygen concentrator can maintain the temperature of the water in the cup body 1 within a certain range by controlling the heating component, ensuring that the humidified oxygen maintains a certain temperature, so that the user can breathe comfortable oxygen. In order to ensure the sealing of the bottom of the cup body 1, multiple circles of convex ribs 71 (such as two circles) can be formed on the upper end surface and the lower end surface of the sealing ring 7.

[0040] See also Figure 1 , Figure 3 , Figure 5 and Figure 6 The constant temperature oxygen tube 3 includes a plug connector 31, a pipeline 32, a heating wire 33, a temperature sensor 34 and a connector 35. One end of the pipeline 32 is installed on the plug connector 31 (such as through a snap structure, a threaded structure, etc.), and the connector 35 is installed on the other end of the pipeline 32 (such as through a snap structure, a threaded structure, etc.). The constant temperature oxygen tube 3 can be plugged into the socket 24 on the adapter 2 through the plug connector 31 to achieve a detachable connection between the constant temperature oxygen tube 3 and the adapter 2. In this way, the oxygen humidification cup structure can be transported and stored as an integral structure. At the same time, it is also convenient to clean the constant temperature oxygen tube 3, the adapter 2 and the cup body 1 separately to ensure hygiene and safety. The constant temperature oxygen tube 3 can be connected to a nasal congestion oxygen inhalation tube or an oxygen inhalation nasal mask through the connector 35. In addition, Figure 1 , Figure 3 and Figure 5The length of the middle pipeline 32 is for illustration only, and its actual length can be designed as required.

[0041] See also Figure 3 and Figure 5 The outer circumference of the pipe 32 is formed with a spiral groove (not shown), and the pipe 32 can be a corrugated pipe, see Figure 6 The heating wire 33 is wound around the pipeline 32, and the heating wire 33 is arranged in a spiral shape. An anti-scalding tube 331 is sleeved on the heating wire 33, that is, the anti-scalding tube 331 is also arranged in a spiral shape. The spirally arranged anti-scalding tube 331 is adaptively accommodated in the spiral groove on the outer periphery of the pipeline 32, and the anti-scalding tube 331 can ensure that the working heating wire 33 will not burn the user; in order to ensure that the heating wire 33 can efficiently heat the oxygen in the pipeline 32, the anti-scalding tube 331 can be formed with an opening along the length direction, and the opening part of the anti-scalding tube 331 is attached to the outer periphery of the pipeline 32, so as to prevent the user from being burned. The heating wire 33 in the tube 331 is directly attached to the spiral groove on the outer periphery of the pipeline 32. In this way, the heating wire 33 can directly pass through the pipeline 32 to efficiently heat the oxygen in the pipeline 32. Moreover, since the anti-scalding tube 331 is adaptively accommodated in the spiral groove on the outer periphery of the pipeline 32, the spirally arranged anti-scalding tube 331 containing the heating wire 33 will not slide freely on the pipeline 32, ensuring that the spirally arranged heating wire 33 can be evenly distributed on the pipeline 32, thereby ensuring the uniformity and stability of the heating of the oxygen in the pipeline 32.

[0042] The temperature sensor 34 is installed at the other end of the pipeline 32. The temperature sensor 34 can detect the temperature of the oxygen output from the pipeline 32. Specifically, in this embodiment, the temperature sensor 34 is installed in the connector 35.

The plug-in holes 352 are located in the grooves 351, and each groove 351 has a plug-in hole 352. A plurality of plugs (e.g., four) are formed on the side of the mounting plate 342 of the temperature sensor 34. The plugs on the side of the mounting plate 342 of the temperature sensor 34 are correspondingly plugged into the plug-in holes 352 on the peripheral wall of the connector 35. In this way, the temperature sensor 34 installed in the connector 35 can accurately detect the temperature of the oxygen discharged from the pipeline 32. The side of the mounting plate 342 of the temperature sensor 34 is clamped in the plug-in hole 352 to ensure that the temperature sensor 34 is firmly installed and will not fall off due to bending or pulling of the pipeline 32, affecting the detection of oxygen. In addition, the presence of the grooves 351 on the outer wall of the connector 35 facilitates the assembly and disassembly of the temperature sensor 34.

[0043] See also Figure 6The wiring harness 341 of the temperature sensor 34 is also accommodated in the anti-scalding tube 331. At the same time, the wiring harness of the heating wire 33 near the connector 35 is accommodated in the anti-scalding tube 331 together with the wiring harness 341 of the temperature sensor 34. In order to prevent the wiring harness of the heating wire 33 and the wiring harness 341 of the temperature sensor 34 from being scalded when the heating wire 33 is working, the wiring harness of the heating wire 33 and the wiring harness 341 of the temperature sensor 34 can be wrapped with an insulating tube.

[0044] See also Figure 5 A connecting terminal 312 is installed on the side of the plug connector 31, the wiring harness of the heating wire 33 is connected to the connecting terminal 312, and the wiring harness of the temperature sensor 34 is connected to the connecting terminal 312. Figure 3 A terminal socket 242 adapted to the connection terminal 312 is installed on the inner bottom of the socket 24. When the plug connector 31 on the constant temperature oxygen tube 3 is plugged into the socket 24 on the adapter 2, the connection terminal 312 on the plug connector 31 is connected to the terminal socket 242 in the socket 24.

[0045] See also Figure 2 A terminal socket 26 connected to the terminal socket 242 is installed on the side of the adapter 2. When the oxygen humidification cup structure is installed on the oxygen concentrator, the terminal socket 26 on the side of the adapter 2 can be connected to the controller port on the oxygen concentrator, so that the controller on the oxygen concentrator can control the operation or stop of the heating wire 33. At the same time, the temperature signal detected by the temperature sensor 34 can be sent to the controller on the oxygen concentrator through the terminal socket 26 for processing.

[0046] See also Figure 3 , obliquely arranged plug-ins 311 are formed on both sides of the plug connector 31, and buckles 3111 are formed on the plug connector 311. Two sloped slots 241 are formed on the inner wall of the socket 24, and the shape of the slot 241 is adapted to the shape of the plug connector 311. A card slot 2411 is formed on the slot 241, and the card slot 2411 is adapted to the buckle 3111 on the plug connector 311; in this way, the plug connector 31 is respectively connected to the card slot 2411 on the socket 24 through the buckles 3111 on the two plug connectors 311, ensuring that the plug connector 31 is firmly connected to the socket 24 and will not be easily The plug connector 31 is easy to disengage.

[0047] See also Figure 3 and Figure 5 The end of the plug connector 31 is formed with a plug tube 313 connected to the pipeline 32. When the plug connector 31 is plugged into the socket 24, the plug tube 313 is plugged into the outlet pipe 23. In this way, when the constant temperature oxygen tube 3 is installed on the adapter 2, the oxygen in the cup body 1 can be directly discharged into the plug tube 313 through the outlet pipe 23 to prevent oxygen from leaking out. In order to improve the sealing performance, a sealing ring can be installed on the plug tube 313. When the plug tube 313 is plugged into the outlet pipe 23, the sealing ring is accommodated between the outer wall of the plug tube 313 and the inner wall of the outlet pipe 23.

[0048] See also Figure 1 , Figure 3 and Figure 5 In order to ensure that the connector 35 can be firmly installed on the end of the pipeline 32, a sleeve 8 can be used to fix the end of the pipeline 32 and the connector 35 together.

[0049] See also Figures 1 to 5The oxygen humidification cup structure of the present invention can be installed on an oxygen concentrator, the connecting pipe 22 on the adapter 2 is connected to the oxygen outlet on the oxygen concentrator, the terminal socket 26 on the side of the adapter 2 is connected to the controller port on the oxygen concentrator, and a heating component can be provided on the oxygen concentrator. After the oxygen humidification cup structure is installed on the oxygen concentrator, the heating component can heat the heat-conducting cover 15 at the bottom of the cup body 1, and the constant temperature oxygen pipe 3 is connected to the nasal plug oxygen inhalation tube or the oxygen inhalation nasal mask through the connector 35; when the oxygen concentrator is working, the oxygen produced by the oxygen concentrator passes through the connecting pipe 22 and the air inlet pipe 21. The air inlet 11 enters the cup body 1. After being moistened by the water in the cup body 1, the oxygen is discharged to the nasal plug oxygen inhalation tube or the oxygen inhalation nasal mask through the air outlet 12, the air outlet pipe 23, the socket 24, the pipeline 32 of the constant temperature oxygen tube 3, and the connector 35 for the user to breathe. The water content of the oxygen discharged from the constant temperature oxygen tube 3 increases, thereby realizing the humidification of the oxygen. In the oxygen humidification cup structure of the present invention, the oxygen humidified by the cup body 1 is directly output to the constant temperature oxygen tube 3. The humidified oxygen does not need to be input back to the pipeline inside the oxygen concentrator, which can avoid the humidified oxygen. The water vapor carried by the oxygen condenses in the pipe inside the oxygen concentrator, ensuring the humidity of the oxygen entering the constant temperature oxygen pipe 3. At the same time, the temperature sensor 34 can detect the temperature of the oxygen output from the pipe 32 in real time to ensure that the temperature of the output oxygen is maintained in a suitable range, so that the user can breathe comfortable oxygen. Moreover, the heating component on the oxygen concentrator can also keep the temperature of the water in the cup body 1 within a certain range. In addition, the constant temperature oxygen pipe 3 is detachably connected to the adapter 2, and the adapter 2 is detachably connected to the cup body 1. The oxygen humidification cup The structure can be transported and stored as an integral structure, and it is also convenient to clean the constant temperature oxygen tube 3, the adapter 2, and the cup body 1 separately to ensure hygiene and safety. At the same time, when the air pressure in the cup body 1 is less than or equal to the set value, the pressure relief block 5 blocks the pressure relief hole 14 downward under the action of its own gravity. When the air pressure in the cup body 1 is greater than the set value, the oxygen in the cup body 1 will push the pressure relief block 5 upward through the pressure relief hole 14, and part of the oxygen will leak out through the notch 131 on the side wall of the convex ring 13, ensuring that the pressure of the oxygen in the cup body 1 is maintained within a reasonable range.
