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 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 humidifier 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 pipe 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 pipe inside the oxygen concentrator. For example, water vapor will condense on the inner wall of the pipe 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 oxygen breathed by the user to be cold. 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 in 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] The cup body has an air inlet and an air outlet on the top;

[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 on 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 socket is provided at the top of the adapter, the top of the air outlet pipe is located in the socket, 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 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 to 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 through the air outlet, the air outlet pipe, the socket, and the constant temperature oxygen tube to the nasal plug oxygen inhalation tube or the oxygen inhalation nasal mask 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. The oxygen humidification cup structure of the present invention directly outputs the oxygen humidified by the cup body to the constant temperature oxygen tube, and the humidified oxygen does not need to be transported Returning the humidified oxygen to the pipeline inside the oxygen concentrator can prevent the water vapor carried by the humidified oxygen 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 a whole structure. At the same time, it is also convenient to clean the constant temperature oxygen tube, adapter, and 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 into the cavity. The cap body cover is provided 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 the set value, the pressure relief block is separated from the pressure relief hole and the gas in the cup body can be discharged 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 is ensured that the cap body always covers the top of the convex ring, and that the bottom of the protrusion on the cap body can always be inserted into the cavity on the pressure relief block, ensuring that the pressure relief block is always located directly above the pressure relief hole.

[0016] Furthermore, the device includes a cover having a bendable strip on its side, the end of which is positioned on the socket, and the cover can be fitted over the top of the socket. Therefore, when the thermostatic oxygen tube is removed from the adapter, the strip can be bent to fit the cover over the top of the socket, preventing foreign matter and dust from entering the socket and ensuring hygiene and safety.

[0017] Furthermore, the invention further comprises a sealing ring. The bottom of the cup body is open, and a heat-conducting cover is provided at the bottom of the cup body. The bottom of the cup body is provided with a convex edge extending outward, and the heat-conducting cover is provided with an inner groove facing the center of the heat-conducting cover. The end face of the sealing ring is provided with multiple convex ribs, and the sealing ring is disposed 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. After the oxygen humidification cup structure is installed on the oxygen concentrator, the heating component can heat the heat-conducting cover, and the heated heat-conducting cover can heat the water in the cup body. The controller of the oxygen concentrator can control the heating component to maintain the temperature of the water in the cup body within a certain range, ensuring that the humidified oxygen maintains a certain temperature, allowing the user to breathe comfortable oxygen. The ribs on the sealing ring can further ensure the sealing of the bottom of the cup body.

[0018] Furthermore, the plug connector is provided with an obliquely arranged plug-in on each side, each plug-in having a snap-on clip. The inner wall of the socket is provided with two slots adapted to the plug-in, and the slots are provided with a slot adapted to the snap-on clip. Therefore, the plug connector is respectively engaged with the slots on the socket via the snap-ons on the two plug-ins, ensuring that the plug connector is firmly engaged with the socket and will not easily fall out. When the plug connector needs to be removed from the socket on the adapter, the two plug-ins are held and pressed inward, so that the snap-ons on the plug-ins come out of the slots, and then the plug connector is pulled outward. The plug connector on the thermostatic oxygen tube and the socket on the adapter are very convenient to install and remove. Moreover, the obliquely arranged plug-ins not only facilitate the plug connector to be inserted into the socket, but also ensure that the snap-ons on the plug-in are engaged with the slots on the slot and will not easily fall out.

[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 provided 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 is 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 in an appropriate 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 disposed on the other end of the tube. The outer wall of the connector is provided with a groove, and the peripheral wall of the connector is provided with a plug-in hole, which is located in the groove. The temperature sensor is disposed in the connector, and the side portion of the temperature sensor is engaged with the plug-in hole. Therefore, the constant-temperature oxygen tube can be connected to a nasal obstruction oxygen tube or an oxygen mask via the connector. The temperature sensor installed in the connector can accurately detect the temperature of the oxygen in the tube. The side portion of the temperature sensor is engaged with the plug-in hole, which ensures that the temperature sensor is securely installed and will not fall off due to bending or pulling of the tube, affecting oxygen detection. In addition, the presence of the groove on the outer wall of the connector facilitates the installation and removal of the temperature sensor.

[0021] Furthermore, an anti-scalding tube is provided over the heating wire, and the wiring harness of the temperature sensor is housed 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 housed in the spiral groove. Therefore, the anti-scalding tube can ensure that the working heating wire will not burn the user. In addition, it can wrap the wiring harness of the temperature sensor, so that the wiring harness of the temperature sensor and the pipeline form a whole. 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 spirally arranged anti-scalding tube is housed in the spiral groove on the outer circumference of the pipeline. In this way, the heating wire and the anti-scalding tube will not slide freely on the pipeline, ensuring that the spirally arranged heating wire can always be evenly distributed on the pipeline, ensuring the uniformity and stability of the heating of the 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, avoiding oxygen leakage. BRIEF DESCRIPTION OF THE DRAWINGS

The air inlet 11, the air outlet 12, and the cup cover 101 can be formed in one piece. 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 makes it convenient to clean the inside of the cup body 1.

[0035] The adapter 2 is mounted on the cup body 1. Specifically, the adapter 2 is mounted on the cup cover 101 of the cup body 1. Figure 4 The bottom of the adapter 2 is equipped with an air inlet pipe 21, and the side of the adapter 2 is equipped with a connecting pipe 22. 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. The adapter 2 is equipped with an air outlet pipe 23, which is longitudinally inserted into the adapter 2. The bottom of the air outlet pipe 23 extends from the bottom of the adapter 2. Figures 1 to 4The top of the outlet pipe 23 extends from the top of the adapter 2. 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 outlet pipe 23 is located in the socket 24. The inlet pipe 21 is plugged into the air inlet 11. The bottom of the outlet pipe 23 is plugged into the air outlet 12. A sealing ring (not shown) is installed on both the inlet pipe 21 and the outlet pipe 23 to ensure the sealing of the connection. The adapter 2 is detachably connected to the cup body 1. The adapter 2 It can be directly removed from the cup cover 101 of the cup body 1, so that the adapter 2 and the cup body 1 can be cleaned separately to ensure hygiene and safety; when the oxygen humidification cup structure is installed on the oxygen concentrator, the connecting pipe 22 on the adapter 2 is connected to the oxygen outlet on the oxygen concentrator. When the oxygen concentrator is working, the oxygen produced by the oxygen concentrator 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 sequence.

[0036] The top of the cup body 1 is provided with a convex ring 13 and a pressure relief hole 14. Figures 1 to 4, the 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 that protrudes upward, and the cup cover 101 is formed with a pressure relief hole 14, and the pressure relief hole 14 is located at the bottom of the space enclosed by the convex ring 13, and the side wall of the convex ring 13 is formed with a notch 131 near the top of the convex ring 13, and the top of the notch 131 is open, and the bottom of the cap body 4 is formed with a convex column 41, and the pressure relief block 5 is formed with a 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 protrusion 41, the bottom of the protrusion 41 is inserted into the cavity 51, the cap body 4 is covered on the top of the protrusion ring 13, in order to ensure that the cap body 4 can be firmly covered on the top of the protrusion ring 13, the top of the protrusion 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 that adapt to the bosses on the protrusion ring 13. When the cap body 4 is covered on the top of the protrusion ring 13, the bosses on the protrusion ring 13 The platform is inserted into the cap body 4 and presses upward on the step on the inner wall of the cap body 4; since the bottom of the boss 41 is inserted into the cavity 51, the pressure relief block 5 has an upper and lower floating space at the bottom of the boss 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 boss 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 in the cup body 1 is 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 protruding 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 Figure 4 The bottom of the adapter 2 is formed with a receiving cavity 25, 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, ensuring 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, cap body 4, cup body 1 and cup cover 101 separately to ensure hygiene and safety.

[0038] See 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. 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 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 circle of convex edges 16 extending outward are formed on the bottom of the cup body 1, and a circle of inner grooves 151 facing the center of the heat-conducting cover 15 are 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 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 Figure 1 、 Figure 3 、 Figure 5 and Figure 6 The constant temperature oxygen tube 3 includes a plug connector 31, a pipe 32, a heating wire 33, a temperature sensor 34 and a connector 35. One end of the pipe 32 is installed on the plug connector 31 (such as by a snap structure, a threaded structure, etc.), and the connector 35 is installed on the other end of the pipe 32 (such as by 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 oxygen tube or an oxygen nasal mask through the connector 35. In addition, Figure 1 、 Figure 3 and Figure 5The length of the middle pipe 32 is for illustration only, and its actual length can be designed as needed.

[0041] See Figure 3 and Figure 5 The outer periphery of the pipe 32 is formed with a spiral groove (not shown). The pipe 32 can be a bellows. Figure 6 The heating wire 33 is wound around the pipe 32, and the heating wire 33 is arranged in a spiral shape. The heating wire 33 is covered with an anti-scalding tube 331, 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 pipe 32. 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 pipe 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 pipe 32 to prevent scalding. The heating wire 33 in the tube 331 is directly attached to the spiral groove on the outer periphery of the pipe 32. In this way, the heating wire 33 can directly pass through the pipe 32 to efficiently heat the oxygen in the pipe 32. Moreover, since the anti-scalding tube 331 is adaptively accommodated in the spiral groove on the outer periphery of the pipe 32, the spirally arranged anti-scalding tube 331 containing the heating wire 33 will not slide freely on the pipe 32, ensuring that the spirally arranged heating wire 33 can be evenly distributed on the pipe 32, thereby ensuring the uniformity and stability of the heating of the oxygen in the pipe 32.

[0042] The temperature sensor 34 is installed at the other end of the pipe 32. The temperature sensor 34 can detect the temperature of the oxygen output from the pipe 32. Specifically, in this embodiment, the temperature sensor 34 is installed in the connector 35. Figure 3 and Figure 5 , a plurality of grooves 351 (such as four) are formed on the outer wall of the connector 35, and a plurality of plug-in holes 352 (such as four) are further formed on the peripheral wall of the connector 35. The plug-in holes 352 are located in the grooves 351, and each groove 351 has a plug-in hole 352. The side of the mounting plate 342 of the temperature sensor 34 is formed with a plurality of plugs (such as four). 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 is installed in the connector 35 to 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 installation and disassembly of the temperature sensor 34.

[0043] See 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 burned 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 Figure 5 The side of the plug connector 31 is equipped with a connecting terminal 312, 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 Figure 2 The side of the adapter 2 is equipped with a terminal socket 26 connected to the terminal socket 242. 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 Figure 3 The two sides of the plug connector 31 are respectively formed with obliquely arranged plugs 311, and a buckle 3111 is formed on the plug connector 311. Two sloped slots 241 are formed on the inner wall of the socket 24. The shape of the slot 241 is adapted to the shape of the plug connector 311. A card groove 2411 is formed on the slot 2411, and the card groove 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 groove 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 on the thermostatic oxygen tube 3 and the socket 24 on the adapter 2 are easily removed. When the plug connector 31 needs to be removed from the socket 24 on the adapter 2, the two plug connectors 311 are held in the hands and pressed inwards. The buckle 3111 on the plug connector 311 is removed from the card slot 2411, and then the plug connector 31 is pulled outwards. The installation and removal of the plug connector 31 on the thermostatic oxygen tube 3 and the socket 24 on the adapter 2 are very convenient. The inclined arrangement of the plug connector 311 not only makes it convenient for the plug connector 31 to be inserted into the socket 24, but also ensures that the buckle 3111 on the plug connector 311 is locked outwards in the card slot 2411 on the slot 241 and will not fall out easily.

[0047] See Figure 3 and Figure 5 The end of the plug connector 31 is formed with a plug tube 313 that is 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 leakage. 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 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 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. 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. The constant temperature oxygen tube 3 is connected to the nasal plug oxygen tube or oxygen nasal mask through the connector 35. When the oxygen concentrator is working, the oxygen produced by the oxygen concentrator is passed 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 in sequence through the air outlet 12, the air outlet pipe 23, the socket 24, the pipe 32 of the constant temperature oxygen tube 3, and the connector 35 to the nasal plug oxygen inhalation tube or the oxygen inhalation nasal mask 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. The oxygen humidification cup structure of the present invention directly outputs the humidified oxygen from the cup body 1 to the constant temperature oxygen tube 3. The humidified oxygen does not need to be input back to the pipe 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 tube 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 tube 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.
