Description

Technical Field

[0001] This application belongs to the field of respiratory therapy equipment technology, and specifically relates to an adjustable gas delivery component suitable for respiratory therapy equipment. Background Technology

[0002] Respiratory therapy devices typically deliver gas to a patient's face mask or nasal mask via tubing, which serves as a fixation device around the user's head. To accommodate different head circumferences, the tubing needs to be adjustable in length. Traditional adjustable tubing often uses bent or pleated wall structures for expansion and contraction, such as corrugated or spiral designs. However, these structures have the following drawbacks:

[0003] Insufficient durability: Repeated bending or stretching can easily lead to fatigue of the pipe wall material of the gas pipeline, resulting in cracks or deformation, which affects the airtightness and service life, as well as the fit with the user's head.

[0004] High manufacturing costs: Complex pleated or corrugated structures require precision mold processing and high material flexibility, which increases production costs;

[0005] Inconvenient adjustment: Traditional structures usually lack an effective positioning mechanism, and after adjustment, they are prone to accidental sliding due to external forces, affecting the stability and comfort of use. Utility Model Content

[0006] This application provides an adjustable gas delivery component suitable for respiratory therapy devices to solve the technical problems of traditional gas delivery components, such as complex structure, poor durability, and inconvenient adjustment.

[0007] The technical solution adopted in this application is as follows:

[0008] An adjustable gas delivery assembly for a respiratory therapy device includes an air inlet and an air outlet, and further includes a first gas delivery section and a second gas delivery section. The first gas delivery section has a first gas delivery channel communicating with the air inlet, and the second gas delivery section has a second gas delivery channel communicating with the air outlet. The first gas delivery section and the second gas delivery section are retractably connected by a connecting member, and the connecting member has a connecting pipe connecting the first gas delivery channel and the second gas delivery channel. The second gas delivery section can move relative to the first gas delivery section through the connecting member to adjust the relative distance between the first gas delivery section and the second gas delivery section.

[0009] The gas transmission assembly described in this application also includes the following additional technical features:

[0010] The connecting member includes a connecting part and a positioning part. The connecting part is installed in the second gas supply section and is hollow inside to form the connecting pipeline. One end of the positioning part is connected to the connecting part, and the other end extends toward the first gas supply channel. The gas supply assembly also includes a fixing member movably installed in the first gas supply section. The fixing member has a locking position that restricts the movement of the positioning part and an unlocking position that releases the restriction on the positioning part. The fixing member can switch between the locking position and the unlocking position.

[0011] One end of the connecting part is installed inside the second air supply section, and the other part moves inside the first air supply section. The positioning part is provided with a plurality of limiting protrusions at intervals along its extension direction. The fixing member is provided with a mating protrusion. When the fixing member is in the locked position, the limiting protrusion abuts against the mating protrusion to limit the displacement of the positioning part.

[0012] The first gas delivery section includes a first housing located on the outer side and a second housing located on the inner side. The second housing is hollow inside to form the first gas delivery channel. The first housing and the second housing are spaced apart to form a clearance cavity between them for the connecting member to pass through. The connecting pipe at least partially encloses the first gas delivery channel.

[0013] The gas delivery assembly further includes a first elastic element acting on the connecting portion. The first elastic element is compressed as the connecting portion is stretched and can retract to drive the connecting portion to move toward the first gas delivery section.

[0014] The inner wall of the second housing is provided with a fixing protrusion, the connecting part is provided with a mounting protrusion, one end of the first elastic member is connected to the mounting protrusion, and the other end abuts against the fixing protrusion. The second housing is provided with a clearance groove for avoiding the mounting protrusion.

[0015] The connecting member further includes an elastic sealing member fixed to the connecting portion, the elastic sealing member abutting against the inner wall of the first housing and the connecting portion respectively.

[0016] The second gas delivery section has a first extreme position close to the first gas delivery section and a second extreme position far away from the first gas delivery section; the connecting part is provided with a first stop protrusion, and when the second gas delivery section is located at the first extreme position, the first stop protrusion abuts against the side wall of the first gas delivery section to restrict the second gas delivery section from moving towards the first gas delivery section; the positioning part is provided with a second stop protrusion, and when the second gas delivery section is located at the second extreme position, the second stop protrusion abuts against the fixing member to restrict the second gas delivery section from moving away from the first gas delivery section.

[0017] The first gas delivery section has a receiving hole for the fixing member to pass through. The fixing member extends and retracts within the receiving hole to switch between the locked position and the unlocked position. When the fixing member is in the locked position, the fixing member protrudes out of the receiving hole.

[0018] The gas delivery assembly also includes a second elastic element that acts on the fixing member, the second elastic element being able to drive the fixing member to switch from the unlocked position to the locked position.

[0019] The air inlet is located in the middle of the first air delivery section. There are two second air delivery sections, which are located on both sides of the first air delivery section. The first air delivery section and the second air delivery section are arc-shaped and form a wearable area for the user to wear.

[0020] The gas supply assembly also includes a gas outlet component located at the gas outlet, wherein the two gas supply ports of the gas outlet component are connected to the gas outlet.

[0021] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0022] 1. The adjustable air delivery component of this application includes a first air delivery section and a second air delivery section, which are respectively connected to an air inlet and an air outlet to deliver airflow to the user. The air delivery component is worn on the user's head, and the first and second air delivery sections fit snugly against the user's head, occupying less space around the user's head and facilitating a lying posture while wearing the component, thus improving user comfort. Furthermore, the air delivery component has a connecting member, through which the first and second air delivery sections are connected. For users with different head circumferences, the relative position between the second and first air delivery sections can be adjusted via the connecting member to improve wearing comfort and enhance the adaptability of the air delivery component. Moreover, the separate design of the first and second air delivery sections and the connecting member allows for separate manufacturing and assembly, simplifying the structure of the air delivery component and helping to reduce the processing and manufacturing difficulty. The separate design of the first gas delivery section, the second gas delivery section, and the connecting parts facilitates the maintenance and replacement of the gas delivery components. When a component in the gas delivery components is damaged, it can be disassembled and repaired or replaced separately, which helps to improve the user's cost-effectiveness.

[0023] Furthermore, the first and second air delivery sections are each equipped with a first air delivery channel and a second air delivery channel, respectively, and the connecting component contains a connecting pipe. When the distance between the first and second air delivery sections is adjusted, the cross-sectional dimensions of the airflow path formed by the first air delivery channel, the connecting pipe, and the second air delivery channel remain unchanged. Therefore, the airflow path will not change in size due to adjustments in the first and second air delivery sections, thereby reducing the probability of pressure changes caused by adjusting the first and second air delivery sections. This helps improve the stability of airflow movement and provides users with a more stable airflow output environment.

[0024] 2. In a preferred embodiment of this application, the combined structure of the connecting part and the positioning part makes the movement of the second gas delivery section relative to the first gas delivery section more stable and controllable. The connecting part serves to connect the first and second gas delivery sections, ensuring stable communication between the first and second gas delivery channels during adjustment of their relative positions, thus guaranteeing the gas delivery stability of the gas delivery assembly. The positioning part's extension towards the first gas delivery channel allows the second gas delivery section to maintain linear movement during adjustment, reducing the probability of obstructed movement of the connecting part due to force misalignment during user adjustment of the gas delivery assembly, thereby increasing user convenience. Furthermore, the fixing element allows for quick locking after adjustment to the appropriate position, preventing relative sliding between the first and second gas delivery sections due to head movement or external forces acting on the gas delivery assembly during use, further improving the operational stability of the gas delivery assembly. The design of switching between the locking and unlocking positions of the fasteners makes the adjustment process of the gas delivery components more flexible. Users can easily adjust the relative positions of the first and second gas delivery sections with simple operations, greatly improving the ease of use.

[0025] 3. In a preferred embodiment of this application, the connecting part moves within the first air delivery section, avoiding interference from the external environment of the air delivery component during its movement, thus improving the adjustment stability of the connecting part. Furthermore, the concealed design of the connecting part reduces the area of ​​the connecting part exposed to the outside, lowering the probability of contamination and reducing the user's cleaning burden. The positioning part has a limiting protrusion, and the fixing part has a mating protrusion, providing the connecting part with multiple adjustment positions. Users can adjust the position of the connecting part and engage the mating protrusion with any limiting protrusion to adjust the relative positions of the second and first air delivery sections. This enhances the adjustment range of the air delivery component, allowing it to adapt to users with larger head circumferences or those requiring post-operative head bandages, meeting the personalized needs of different users. Secondly, the abutting design of the limiting protrusion and the mating protrusion provides a more reliable locking effect. When the air supply assembly is subjected to external friction or other factors that cause a relative displacement tendency between the first and second air supply sections, the engagement of the limiting protrusion and the mating protrusion can generate a self-locking effect, effectively preventing accidental displacement. Furthermore, when the connecting part is adjusted to the correct position and the fixing part switches from the unlocked position to the locked position, the engagement of the limiting protrusion and the mating protrusion will produce a distinct "click" sound and tactile feedback, helping the user confirm successful locking. This dual tactile and auditory feedback is particularly suitable for users at night or with poor eyesight, reducing the probability of user error.

[0026] 4. In a preferred embodiment of this application, the first gas delivery section is configured to include a first housing and a second housing. This dual-housing design significantly improves the space utilization of the first gas delivery section. The first housing, as an external protective layer, can be made of wear-resistant and impact-resistant materials to improve product durability. The second housing, as an internal gas passage, can be made of smooth, low-resistance materials to optimize airflow characteristics. The clearance cavity between the two provides ample space for the connecting component to move, ensuring that the connecting component does not interfere with the first gas delivery passage during expansion and contraction, guaranteeing smooth adjustment of the connecting component. Furthermore, the design of the connecting pipe at least partially enclosing the first gas delivery passage further enhances the sealing effect of the gas delivery assembly.

[0027] 5. In a preferred embodiment of this application, the first stop boss and the second stop boss define the first and second limit positions of the second air supply section, providing clear physical limits for the adjustment of the air supply assembly. This prevents the second air supply section from being over-compressed, which could cause compression between the second air supply section and the first air supply section, as well as the connecting member, thus ensuring the structural stability of the air supply assembly. Simultaneously, it prevents the second air supply section from being excessively stretched relative to the first air supply section, which could cause the second air supply section to detach from the first air supply section. Users do not need to precisely control the force to prevent the second air supply section from detaching when stretching it, which helps improve the user experience when adjusting the air supply assembly.

[0028] 6. In a preferred embodiment of this application, the receiving hole provides installation space for the fastener, and when the user controls the movement of the fastener, the receiving hole provides guidance, guiding the fastener to move along the extension direction of the receiving hole to switch between the unlocked and locked positions. This compensates for force deviations in the fastener caused by user error or improper operation, thereby improving the working stability of the fastener. Furthermore, the receiving hole also provides a certain degree of protection for the fastener, reducing interference from the external environment. When the fastener is in the locked position, it protrudes outward from the receiving hole, making it easy for the user to press the fastener to move it, eliminating the need for the user to insert their fingers into the narrow receiving hole to control the movement of the fastener, thus improving the ease of operation of the fastener.

[0056] like Figures 1 to 3 As shown, an adjustable gas delivery assembly suitable for a respiratory therapy device includes an air inlet 1 and an air outlet 2. The assembly also includes a first gas delivery section 3 and a second gas delivery section 4. The first gas delivery section 3 has a first gas delivery channel 31 communicating with the air inlet 1, and the second gas delivery section 4 has a second gas delivery channel 41 communicating with the air outlet 2. The first gas delivery section 3 and the second gas delivery section 4 are retractably connected by a connecting member 5. The connecting member 5 has a connecting pipe 51 that connects the first gas delivery channel 31 and the second gas delivery channel 41. The second gas delivery section 4 can move relative to the first gas delivery section 3 through the connecting member 5 to adjust the relative distance between the first gas delivery section 3 and the second gas delivery section 4.

[0057] The adjustable air delivery component of this application includes a first air delivery section 3 and a second air delivery section 4, which are respectively connected to an air inlet 1 and an air outlet 2 to deliver airflow to the user. The air delivery component is worn on the user's head, and the first air delivery section 3 and the second air delivery section 4 fit snugly against the user's head, occupying less space around the user's head and facilitating a lying posture while wearing the component, thus improving user comfort. Furthermore, the air delivery component is equipped with a connecting member 5, through which the first air delivery section 3 and the second air delivery section 4 are connected. For users with different head circumferences, the relative position between the second air delivery section 4 and the first air delivery section 3 can be adjusted via the connecting member 5 to improve wearing comfort and enhance the adaptability of the air delivery component. Moreover, the separate design of the first air delivery section 3, the second air delivery section 4, and the connecting member 5 allows for separate manufacturing and assembly, simplifying the structure of the air delivery component and helping to reduce the processing and manufacturing difficulty. The separate design of the first gas delivery section 3, the second gas delivery section 4, and the connecting component 5 facilitates the maintenance and replacement of the gas delivery assembly. When a component in the gas delivery assembly is damaged, it can be disassembled and repaired or replaced separately, which helps to improve the user's cost-effectiveness.

[0058] Furthermore, the first air delivery section 3 and the second air delivery section 4 are respectively provided with a first air delivery channel 31 and a second air delivery channel 41, and the connecting member 5 is provided with a connecting pipe 51. When the distance between the first air delivery section 3 and the second air delivery section 4 is adjusted, the cross-sectional dimensions of the airflow path formed by the first air delivery channel 31, the connecting pipe 51, and the second air delivery channel 41 will not change. Therefore, the airflow path will not change in size due to the adjustment of the first air delivery section 3 and the second air delivery section 4, thereby reducing the probability of pressure changes in the airflow caused by adjusting the first air delivery section 3 and the second air delivery section 4. This helps to improve the stability of airflow movement and provides users with a more stable airflow output environment.

[0059] Specifically, the air inlet 1 of the gas delivery component is connected to the air supply unit of the respiratory therapy device. The air supply unit mixes air and oxygen, and then inputs the mixed airflow into the air inlet 1.

[0060] As a preferred embodiment of this application, such as Figures 2 to 5 As shown, the connecting member 5 includes a connecting part 52 and a positioning part 53. The connecting part 52 is installed on the second gas supply section 4 and is hollow inside to form a connecting pipe 51. One end of the positioning part 53 is connected to the connecting part 52, and the other end extends toward the first gas supply channel 31. The gas supply assembly also includes a fixing member 6 that is movably installed on the first gas supply section 3. The fixing member 6 has a locking position that restricts the movement of the positioning part 53 and an unlocking position that releases the restriction on the positioning part 53. The fixing member 6 can switch between the locking position and the unlocking position.

[0061] For ease of understanding, Figure 5The diagram schematically illustrates the movement directions of the connecting member 5 and the fixing member 6. The double-headed arrow X indicates the movement direction of the connecting member 5, and the double-headed arrow Y indicates the movement direction of the fixing member 6. The combined structure of the connecting part 52 and the positioning part 53 makes the movement of the second air supply section 4 relative to the first air supply section 3 more stable and controllable. The connecting part 52 connects the first air supply section 3 and the second air supply section 4, ensuring stable communication between the first air supply channel 31, the connecting pipe 51, and the second air supply channel 41 during the adjustment of their relative positions, thus guaranteeing the stability of the air supply assembly. The design of the positioning part 53 extending towards the first air supply channel 31 allows the second air supply section 4 to maintain linear movement during adjustment, reducing the probability of obstruction of the connecting member 5 due to force misalignment during user adjustment of the air supply assembly, and increasing user convenience. Furthermore, the fastener 6 allows users to quickly lock it in place after adjusting it to the appropriate position, preventing the first air delivery section 3 and the second air delivery section 4 from sliding relative to each other due to head movement or external forces acting on the air delivery assembly during use, thus further improving the working stability of the air delivery assembly. The switchable locking and unlocking design of the fastener 6 makes the adjustment process of the air delivery assembly more flexible; users can easily adjust the relative positions of the first air delivery section 3 and the second air delivery section 4 with simple operations, greatly improving ease of use.

[0062] This embodiment does not limit the structural form of the connecting part 52 and the positioning part 53. They can be set as integrally formed; or they can be manufactured separately and then installed and connected. They can be fixedly connected or detachably connected by means of snap-fit ​​or plug-in.

[0063] Similarly, this application does not limit the positional relationship between the connecting part 5 and the first air supply section 3. It can also be that one end of the positioning part 53 is connected to the connecting part 52, and the other end extends along the outer surface of the first air supply section 3.

[0064] As a preferred embodiment of this implementation, such as Figure 4 , Figure 5 As shown, one end of the connecting part 52 is installed inside the second air supply section 4, and the other part moves inside the first air supply section 3. The positioning part 53 is provided with a plurality of limiting protrusions 531 at intervals along its extension direction. The fixing member 6 is provided with a mating protrusion 61. When the fixing member 6 is in the locked position, the limiting protrusions 531 abut against the mating protrusions 61 to limit the displacement of the positioning part 53.

[0065] The connecting part 52 moves inside the first air supply section 3, avoiding interference from the external environment of the air supply component during its movement, which helps improve the adjustment stability of the connecting part 5. Furthermore, the concealed design of the connecting part 52 reduces the area of ​​the connecting part 5 exposed to the outside, lowering the probability of contamination and thus reducing the cleaning burden on the user. The positioning part 53 is provided with a limiting protrusion 531, and the fixing part 6 is provided with a mating protrusion 61, giving the connecting part 5 multiple adjustment positions. Users can adjust the position of the connecting part 5 and engage the mating protrusion 61 with any limiting protrusion 531 to achieve different relative positions between the second air supply section 4 and the first air supply section 3. This enhances the adjustment range of the air supply component, allowing it to adapt to users with larger head circumferences or those who have undergone post-operative head bandages, meeting the personalized needs of different users. Secondly, the abutting design of the limiting protrusion 531 and the mating protrusion 61 provides a more reliable locking effect. When the air supply assembly is subjected to external friction or other factors, causing a relative displacement tendency between the first air supply section 3 and the second air supply section 4, the engagement of the limiting protrusion 531 and the mating protrusion 61 can generate a self-locking effect, effectively preventing accidental displacement. Furthermore, when the connecting member 5 is adjusted to the correct position and the fixing member 6 switches from the unlocked position to the locked position, the engagement of the limiting protrusion 531 and the mating protrusion 61 will produce a distinct "click" sound and tactile feedback, helping the user confirm successful locking. This dual tactile and auditory feedback is particularly suitable for users at night or with poor eyesight, reducing the probability of user misoperation.

[0066] Specifically, in this embodiment, a limiting groove is formed between two adjacent limiting protrusions 531. When the fixing member 6 is in the locked position, the mating protrusion 61 is embedded in the limiting groove and abuts against the limiting protrusion 531 to restrict the movement of the communicating part 52. Preferably, the size of the limiting groove is slightly larger than the mating protrusion 61 to reduce jamming when the mating protrusion 61 enters or exits.

[0067] As a preferred example in this embodiment, such as Figure 6 As shown, the first gas delivery section 3 includes a first housing 32 located on the outside and a second housing 33 located on the inside. The interior of the second housing 33 is hollow to form a first gas delivery channel 31. The first housing 32 and the second housing 33 are spaced apart to form a clearance cavity 7 between them for the connecting member 5 to pass through. The connecting pipe 51 at least partially encloses the first gas delivery channel 31.

[0068] The first air delivery section 3 is configured to include a first housing 32 and a second housing 33. This dual-housing design significantly improves the space utilization of the first air delivery section 3. The first housing 32, as the outer protective layer, can be made of wear-resistant and impact-resistant materials to improve product durability. The second housing 33, as the internal air passage, can be made of smooth, low-resistance materials to optimize airflow characteristics. The clearance cavity 7 between the two provides ample space for the connecting member 5 to move, ensuring that the connecting member 5 will not interfere with the first air delivery channel 31 during extension and retraction, guaranteeing the smoothness of the adjustment process of the connecting member 5. Furthermore, the design of the connecting pipe 51 at least partially enclosing the first air delivery channel 31 further enhances the sealing effect of the air delivery assembly. Of course, this example does not limit the manufacturing materials and methods of the first housing 32 and the second housing 33. The first housing 32 and the second housing 33 can be integrally manufactured from the same material, or they can be manufactured separately and then assembled; alternatively, the first housing 32 and the second housing 33 can be made from different materials and then assembled.

[0069] As a preferred approach in this example, such as Figure 7 As shown, the gas delivery assembly also includes a first elastic member 8 acting on the connecting portion 52. The first elastic member 8 is compressed as the connecting member 5 is stretched, and can retract to drive the connecting member 5 to move toward the first gas delivery section 3.

[0070] By incorporating the first elastic element 8, the second air delivery section 4 acquires an automatic retraction function, greatly improving the ease of adjustment. The rebound force of the first elastic element 8 automatically retracts excessively long pipes to a suitable position; the user simply needs to unlock the fixing element 6. This flexible design is particularly suitable for users with limited mobility or poor hand dexterity, enhancing the user experience.

[0071] Secondly, the first elastic element 8 optimizes the dynamic stability of the gas delivery pipeline. During the use of the respiratory therapy device, the locking mechanism may fail due to accidental contact or loosening of the fixing element 6, causing the second gas delivery section 4 to tend to shift relative to the first gas delivery section 3. The first elastic element 8 provides a pre-tightening force between the second gas delivery section 4 and the first gas delivery section 3, preventing the second gas delivery section 4 from detaching from the first gas delivery section 3 even if the fixing element 6 becomes loose, thus improving the operational stability of the gas delivery assembly. In addition, respiratory therapy devices are often used when users are resting at night. During use, users may move their heads, which may exert intermittent tension on the pipeline. The first elastic element 8 can buffer this dynamic tension, maintaining the relative stability of the pipeline length, while avoiding excessive stress on the connection points, thus ensuring the operational stability of the gas delivery assembly.

[0072] Preferably, the first elastic element 8 can be a spring.

[0073] Preferably, such as Figure 7 , Figure 8 As shown, the inner wall of the second housing 33 is provided with a fixing protrusion 331, the connecting part 52 is provided with a mounting protrusion 521, one end of the first elastic member 8 is connected to the mounting protrusion 521, and the other end abuts against the fixing protrusion 331. The second housing 33 is provided with a relief groove 332 for avoiding the mounting protrusion 521.

[0074] The fixed protrusion 331 and the mounting protrusion 521 provide a mounting position for the first elastic element 8, and the cooperative design of the fixed protrusion 331 and the mounting protrusion 521 ensures the accurate positioning and reliable fixation of the first elastic element 8, ensuring that the first elastic element 8 stably applies elastic force to the second air delivery section 4. Secondly, the design of the clearance groove 332 optimizes the movement trajectory and space utilization of the connecting member 5. The clearance groove 332 provides a dedicated moving channel for the mounting protrusion 521, ensuring that the connecting member 5 does not interfere with the second housing 33 during extension and retraction, resulting in smoother movement.

[0075] Furthermore, such as Figure 8 As shown, the connecting member 5 also includes an elastic sealing member 522 fixed to the connecting portion 52, and the elastic sealing member 522 abuts against the inner wall of the first housing 32 and the connecting portion 52 respectively.

[0076] The elastic seal 522 reduces the probability of gas leakage between the connecting part 52 and the first housing 32, helping to improve the airtightness of the gas delivery assembly and optimizing its structural design. Furthermore, the elastic seal 522 provides a misalignment allowance for the installation of the connecting part 52 and the first housing 32. Due to factors such as manufacturing or installation deviations, there may be slight misalignment between the connecting part 52 and the first housing 32. The elastic contraction characteristics of the elastic seal 522 allow it to have a certain amount of compression, adapting to pressure changes at the installation positions of the connecting part 52 and the first housing 32, maintaining a good sealing effect. In addition, vibrations generated during the operation of the respiratory therapy device may be transmitted to the gas delivery assembly, and airflow movement and friction between the gas delivery assembly can also cause minor vibrations. By incorporating the elastic seal 522, the vibrational potential energy of these minor vibrations can be converted into the elastic potential energy required for deformation, thereby reducing vibration, improving user comfort, and reducing noise caused by vibration, thus enhancing the user experience in multiple ways.

[0077] Preferably, the elastic seal 522 is a rubber component.

[0078] As another preferred example under this embodiment, such as Figure 9As shown, the second gas delivery section 4 has a first extreme position close to the first gas delivery section 3 and a second extreme position far away from the first gas delivery section 3; the connecting part 52 is provided with a first stop boss 523, when the second gas delivery section 4 is in the first extreme position, the first stop boss 523 abuts against the side wall of the first gas delivery section 3 to restrict the movement of the second gas delivery section 4 towards the first gas delivery section 3; the positioning part 53 is provided with a second stop boss 532, when the second gas delivery section 4 is in the second extreme position, the second stop boss 532 abuts against the fixing member 6 to restrict the movement of the second gas delivery section 4 away from the first gas delivery section 3.

[0079] The first stop boss 523 and the second stop boss 532 define the first and second limit positions of the second air supply section 4, providing clear physical limits for the adjustment of the air supply assembly. This prevents the second air supply section 4 from being over-compressed, which could cause compression between the second air supply section 4 and the first air supply section 3 and the connecting member 5, thus ensuring the structural stability of the air supply assembly. Simultaneously, it prevents the second air supply section 4 from being excessively stretched relative to the first air supply section 3, which could cause it to detach from the first air supply section 3. Users do not need to precisely control the force to prevent the second air supply section 4 from detaching when stretching it, thus improving the user experience when adjusting the air supply assembly.

[0080] As a preferred embodiment of this implementation, such as Figure 4 As shown, the first gas delivery section 3 has a receiving hole 34 for the fastener 6 to pass through. The fastener 6 extends and retracts within the receiving hole 34 to switch between a locked position and an unlocked position. When the fastener 6 is in the locked position, the fastener 6 protrudes out of the receiving hole 34.

[0081] The receiving hole 34 provides installation space for the fixing member 6. When the user controls the movement of the fixing member 6, the receiving hole 34 provides a guiding function, directing the fixing member 6 to move along the extension direction of the receiving hole 34 to switch between the unlocked and locked positions. This compensates for force deviations in the fixing member 6 caused by user error or improper operation, thus improving the working stability of the fixing member 6. Furthermore, the receiving hole 34 also provides a certain degree of protection for the fixing member 6, reducing interference from the external environment. When the fixing member 6 is in the locked position, it protrudes outward from the receiving hole 34, making it easier for the user to press the fixing member 6 to move it. This eliminates the need for the user to insert their fingers into the narrow receiving hole 34 to control the movement of the fixing member 6, improving the ease of operation of the fixing member 6.

[0082] As a preferred example in this embodiment, such as Figure 5 As shown, the gas delivery assembly also includes a second elastic member 9 acting on the fixing member 6, which can drive the fixing member 6 to switch from the unlocked position to the locked position.

[0083] The second elastic element 9 significantly reduces the difficulty of using the fixing element 6. Users only need to press the fixing element 6 with one hand while adjusting the second air delivery section 4 with the other. After adjustment, releasing the fixing element 6 allows it to move to the locked position under the action of the second elastic element 9, thus locking the air delivery assembly. This eliminates the need for users to reset the fixing element 6 after adjustment, greatly improving the user experience. Furthermore, the second elastic element 9 provides a locking force to the fixing element 6 in the locked position, ensuring its stability and reducing accidental unlocking due to vibration of the air delivery assembly or accidental contact with the fixing element 6, thereby improving the operational stability of the air delivery assembly.

[0084] As a preferred embodiment of this application, such as Figure 1 As shown, the air inlet 1 is located in the middle of the first air supply section 3, and there are two second air supply sections 4 located on both sides of the first air supply section 3. The first air supply section 3 and the second air supply section 4 are arc-shaped and form a wearable area 10 for the user to wear.

[0085] The curved structure conforms well to the contours of the human head. Compared to the abruptness and pressure of straight tubes, the curved tube offers better wearing comfort and enhances the user's wearing experience. Positioning the air inlet 1 in the middle of the first air delivery section 3 and having two second air delivery sections 4 on either side of the first air delivery section 3 achieves central air intake and lateral air exhaust, optimizing airflow distribution. Airflow enters the two second air delivery sections 4 from the central air inlet 1, with symmetrical and equal flow paths, ensuring balanced airflow pressure in both nostrils and improving breathing comfort. Furthermore, the curved design of the first and second air delivery sections 3 and 4 keeps the tubes naturally away from the face, providing ample space for the wearer. The symmetrical design of the two second air delivery sections 4 also allows for free switching between left and right side lying positions without causing pressure on one side of the tube.

[0086] Preferably, such as Figure 1 As shown, the gas supply assembly also includes an air outlet 110 located at the air outlet 2, with two air supply ports of the air outlet 110 connected to the air outlet 2.

[0087] The configuration of the air supply component provides a variety of choices for different user needs. The form of the air outlet component 110 is not limited. For example, the air outlet component 110 can be a nasal mask that covers the user's nose, with the air supply port located at the end of the nasal mask; it can also be an oral-nasal mask with multiple air supply ports located at the mouth and nose of the oral-nasal mask respectively.
