For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0052] Please refer to Figures 1 to 3 The first embodiment of the present application provides a glue-free and chemical solvent-free gas sampling tube 10 for respiratory therapy equipment, wherein the gas sampling tube includes an air supply pipe 11, a gas sampling tube connector 12 and a locking member 14. The gas sampling tube 10 realizes a stable connection between the gas sampling tube 10 connector and the air supply pipe 11 through the additional locking member 14, thereby replacing the solution of connecting the gas sampling tube 10 connector and the air supply pipe 11 through glue and chemical solvents in the prior art, thereby providing a new type of glue-free and chemical solvent-free gas sampling tube 10, which fundamentally avoids the release of volatile organic substances, simplifies the production process, and significantly improves the safety and reliability of the product. At the same time, the locking member 14 is used to mechanically connect the gas sampling tube 10 connector and the air supply pipe 11, without waiting for the glue to air-dry and solidify, shortening the manufacturing time of the gas sampling tube 10 and improving the production capacity of the gas sampling tube 10.

[0053] Please refer to Figures 1 to 3In some embodiments, the gas sampling tube 10 includes a gas pipe 11, a gas sampling pipe connector 12, and a connector lock 13; during the actual assembly process, one end of the gas pipe 11 is first passed through the through hole 131 of the connector lock 13, and then the gas pipe 11 is inserted into the first inverted fastener 121 and the first pipe entry 122. The first inverted fastener 121 can prevent the gas pipe 11 from accidentally detaching from the first pipe entry 122. The several fixing members 132 provided on the connector lock 13 are used to firmly fix the gas pipe 11 in the first pipe entry 122. When the gas pipe 11 is inserted into the first pipe entry 122, the abutment boss 1231 under the first pipe entry 122 cooperates with the anti-stuck protrusion 1232 to form a clamping area, ensuring that the gas pipe 11 is stably positioned during the assembly process and preventing the gas pipe 11 from falling off or loosening. When the connector lock 13 is displaced downward and buckled into the clamping area, the fixing member 132 is stretched outward by the expansion portion 1233, further ensuring the stable connection of the gas pipe 11. The fastener 1321 is composed of a deformation portion 1322 and a clamping portion 1323. The clamping portion 1323 has an abutment section 1324, a side support section 1325 and a stop section 1326. When the connector lock 13 is buckled downward, the deformation portion 1322 of the fastener 1321 is bent, and the abutment section 1324 of the clamping portion 1323 first contacts the expansion portion 1233, causing the fixing member 132 to gradually stretch out. As the connector lock 13 continues to be pressed downward, the side support section 1325 abuts against the side wall of the abutment boss 1231, providing additional support force, further enhancing the stability of the connection. Finally, the locking section 1326 enters the clamping area and locks, firmly fixing the gas pipe 11 in the first buckle 121 and the first pipe inlet 122 of the gas sampling pipe connector 12, and finally making the connection between the gas pipe 11 and the gas sampling pipe connector 12 firm and not loose. Furthermore, through this mechanical connection method, the entire assembly process does not require the use of chemical adhesives. After assembly, the gas sampling tube 10 has good sealing properties to avoid gas leakage, which not only simplifies the production process but also significantly improves the safety and reliability of the product. The gas sampling tube 10 uses a mechanical connection method instead of the traditional glue curing process, which fundamentally avoids the release of volatile organic compounds and improves the safety of the gas sampling tube 10. At the same time, the use of the mechanical connection process does not require air drying and curing time, shortens the manufacturing time of the gas sampling tube 10, and improves the production capacity of the gas sampling tube 10.

[0054] Please refer to Figures 1 to 3In some embodiments, the gas sampling tube 10 includes a gas delivery tube 11, a gas sampling tube connector 12 and a connector lock 13, the gas delivery tube 11 is used to deliver or output gas, the gas sampling tube connector 12 is used to be detachably connected to the respiratory therapy device, and the connector lock 13 is used to cooperate with the gas sampling tube connector 12 to fix the gas delivery tube 11 in the gas sampling tube 10; the gas sampling tube connector 12 has a first inverted fastener 121, a first pipe entry piece 122, a locking portion 123 and a first sleeve 124, the first inverted fastener 121, the first pipe entry piece 122, the locking portion 123 and the first sleeve 124 are arranged in sequence from top to bottom; the first sleeve 124 is used to be sleeved on the respiratory therapy device, the first pipe entry piece 122 and the gas delivery tube 11 is detachable and connected; the joint lock buckle 13 is provided with a through hole 131, and the aperture of the through hole 131 is slightly larger than the aperture of the gas pipe 11, thereby ensuring that the gas pipe 11 can smoothly pass through the through hole 131; a plurality of fixing parts 132 are fixedly provided on the joint lock buckle 13, and the plurality of fixing parts 132 are used to cooperate with the locking part 123 and the gas sampling pipe joint 12 to fix the gas pipe 11 in the first pipe inlet part 122, thereby making the gas sampling pipe 10 adopt a mechanical connection method instead of the traditional glue curing process, fundamentally avoiding the release of volatile organic substances, improving the safety of the gas sampling pipe 10, and at the same time, the use of the mechanical connection process does not require air drying and curing time, shortening the manufacturing time of the gas sampling pipe 10, and improving the production capacity of the gas sampling pipe 10.

[0055] Please refer to Figure 3 In some embodiments, several of the locking portions 123 include an abutting boss 1231 and an anti-stuck protrusion 1232; the abutting boss 1231 is arranged below the first pipe entry member 122, and the abutting boss 1231 is arranged above the first sleeve member 124, that is, the abutting boss 1231 is arranged between the first pipe entry member 122 and the first sleeve member 124, which is conducive to sleeve-fitting the gas delivery pipe 11 into the first pipe entry member 122; the anti-stuck protrusion 1232 is arranged at one end of the abutting boss 1231 away from the first pipe entry member 122, and the anti-stuck protrusion 1232 is arranged at the end of the abutting boss 1231 away from the first pipe entry member 122, and the anti-stuck protrusion 1232 is arranged at the end of the abutting boss 1231 away from the first pipe entry member 122. 232 is integrally formed with the first sleeve 124 and the abutment boss 1231, and the anti-stuck protrusion 1232 connects the first sleeve 124 and the abutment boss 1231, thereby enhancing the overall structural stability of the first sleeve 124 and the abutment boss 1231, so that it can withstand greater external force and impact; the anti-stuck protrusion 1232 is used to separate the space between the abutment boss 1231 and the first sleeve 124 into a clamping area, thereby providing a clear clamping path and position for the connector lock 13, avoiding the risk of misaligned clamping and accidental falling off of the connector lock 13.

[0056] Please refer to Figure 2 and Figure 3 In some embodiments, the abutting boss 1231 is provided with an expansion portion 1233, and the expansion portion 1233 is provided at one end close to the first inlet pipe 122. The expansion portion 1233 is used to expand the plurality of the fixing members 132 outward, thereby helping the fixing members 132 to expand outward under the action of external force during the insertion process, so that the plurality of the fixing members 132 can adapt to the abutting boss 1231 of different sizes and shapes, thereby improving the connection between the joint lock buckle 13 and the gas take-off. The compatibility and flexibility of the mechanical connection of the gas sampling tube connector 12; the angle between the tangent of the expansion portion 1233 and the axis along the gas sampling tube connector 12 is set to 20°~80°, and the angle between the tangent of the expansion portion 1233 and the axis along the gas sampling tube connector 12 can be specifically set to 20°, 30° or 80°, thereby ensuring that the fixing part 132 is subjected to uniform force during the expansion process, avoiding stress concentration on the fixing part 132, and causing the risk of damage and failure of the fixing part 132.

[0057] Please refer to Figure 2 and Figure 3 In some embodiments, several fixing members 132 include several extrusion fasteners 1321, and several of the extrusion fasteners 1321 are fixedly arranged on the end of the joint lock 13 away from the through hole 131; several of the extrusion fasteners 1321 include a deformation portion 1322 and a snap portion 1323, and the deformation portion 1322 is used to temporarily deform the snap portion 1323 when it is subjected to external force, and restore to its original shape when it is not subjected to external force or the external force disappears, so that the joint lock 13 can achieve better deformation and snapping effects during the snapping process, thereby ensuring the stability and reliability of the connection between the joint lock 13 and the locking portion 123.

[0058] Please refer to Figure 4In some embodiments, the buckle portion 1323 is provided with an abutting section 1324, a side support section 1325 and a locking section 1326; the abutting section 1324, the side support section 1325 and the locking section 1326 are integrally formed, and then the synergistic effect of the abutting section 1324, the side support section 1325 and the locking section 1326 ensures that the joint lock 13 can be accurately locked into the locking area and achieve a stable locking effect; the tangent line of the abutting section 1324 and the locking section 132 The tangent angle of 6 is set to 10° to 90°, and the angle between the tangent of the abutting section 1324 and the tangent of the locking section 1326 is specifically set to 10°, 60° or 90°, thereby achieving a smooth transition of the buckle portion 1323 from the initial abutment to the final locking, improving the accuracy and stability of the connection between the joint lock 13 and the locking portion 123, wherein the gas pipe 11 passes through the through hole 131, and the gas pipe 11 is sleeved on the first inverted fastener 12 1 and the first pipe inlet 122, so that the joint lock buckle 13 is displaced toward the gas sampling tube joint 12, the abutting section 1324 abuts against the expansion portion 1233, the expansion portion 1233 is stretched outward, driving the deformation portion 1322 to bend, and the side support section 1325 abuts against the side wall of the abutting boss 1231, so that the locking section 1326 is locked in the locking area, and then through this mechanical connection method, the entire assembly process does not require the use of chemical adhesives. After the assembly is completed, the gas sampling tube 10 has good sealing performance to avoid gas leakage, which not only simplifies the production process but also significantly improves the safety and reliability of the product. The gas sampling tube 10 adopts a mechanical connection method instead of the traditional glue curing process, which fundamentally avoids the release of volatile organic substances and improves the safety of the gas sampling tube 10. At the same time, the mechanical connection process does not require air drying and curing time, shortens the manufacturing time of the gas sampling tube 10, and improves the production capacity of the gas sampling tube 10.

[0059] In some embodiments, the connector lock 13 also includes a first ultrasonic line, which is arranged on the end of the connector lock 13 away from the through hole 131. The first ultrasonic line is used to perform ultrasonic welding with the gas sampling tube connector 12, so that the contact surface between the connector lock 13 and the gas sampling tube connector 12 is melted and recombined under high temperature and high pressure to form a seamless connection, effectively improving the sealing of the connection and reducing the risk of gas leakage. At the same time, ultrasonic welding can be performed directly during the assembly process of the gas sampling tube 10 without the need for additional glue curing time or UV light irradiation, further simplifying the assembly process and improving the production efficiency of the gas sampling tube 10.

[0060] In some embodiments, the cross-section of the first ultrasonic line along the axis of the joint lock 13 is configured as a cone, triangle, or pyramid, thereby facilitating the propagation and focusing of the ultrasonic wave during the welding process, thereby improving the efficiency and quality of the welding. These shapes can better guide the ultrasonic energy, forming a uniform weld point on the contact surface.

[0061] In some embodiments, the diameter of the first ultrasonic line is set to 1.1 to 2 times the diameter of the through hole 131, that is, the first ultrasonic line is set on the outside of the water inlet, thereby optimizing the welding effect of the gas sampling pipe connector 12 and the connector lock 13, ensuring the strength and airtightness of the connection part between the gas sampling pipe connector 12 and the connector lock 13, and improving the reliability of the overall structure. The diameter of the first ultrasonic line is larger than the diameter of the through hole 131, which can evenly transfer the stress during welding, reduce stress concentration, and improve the fatigue resistance of the connection part between the gas sampling pipe connector 12 and the connector lock 13.

[0062] Please refer to Figures 5 and 6 In some embodiments, the first fastener 121 is conical, and the maximum diameter of the first fastener 121 is slightly larger than the diameter of the gas pipe 11, thereby effectively preventing the gas pipe 11 from being pulled out of the first fastener 121 after being subjected to force, thereby improving the assembly efficiency of the gas pipe 11 and the gas sampling pipe connector 12.

[0063] In some embodiments, the sharper the top of the first ultrasonic line is, the better, so that the vibration energy can be concentrated at the tip of the triangle, and the accumulated heat can then form a uniform plastic melt flow in the entire welding interface, thereby improving welding efficiency and quality, making the connection between the gas sampling tube connector 12 and the connector lock 13 more stable, thereby abandoning the process of using glue for curing, eliminating the safety risks caused by the volatilization of volatile organic substances, ensuring the safety of the user, and eliminating the need for air drying and curing time, shortening the manufacturing time and cost of the gas sampling tube 10, and improving the production capacity of the gas sampling tube 10 product.

[0064] In some embodiments, the principle of the first ultrasonic wire welding is to utilize the high-frequency vibration of the welding head of the first ultrasonic wire to cause high-frequency friction between the contact surface of the gas sampling tube connector 12 and the connector lock 13, thereby converting mechanical energy into thermal energy. The thermal energy dissolves the molecules on the welding surface of the gas sampling tube connector 12 and the connector lock 13, restoring their activity, and then, with the assistance of external force, the molecules entangle with each other to achieve the welding purpose, thereby greatly improving the airtightness and welding quality between the gas sampling tube connector 12 and the connector lock 13, avoiding the loosening problem that may be caused by traditional glue connection, abandoning the process of using glue for curing, eliminating the safety risks caused by the volatilization of volatile organic substances, ensuring the safety of users, improving the safety of equipment, and requiring no air drying and curing time, thereby shortening the manufacturing time and cost of the gas sampling tube 10 and improving the production capacity of the gas sampling tube 10 product.

[0065] Please refer to Figure 7 In some embodiments, several of the locking portions 123 include a locking boss 1234, and the locking boss 1234 is fixedly arranged above the first pipe inlet 122; thereby, the gas sampling pipe connector 12 can be quickly installed and fixed, simplifying the assembly process and improving production efficiency.

[0066] Please refer to Figure 7In some embodiments, the plurality of fixing members 132 include a plurality of screw members 1327, and the plurality of screw members 1327 are fixedly arranged on the inner side wall of the joint lock 13, and the plurality of screw members 1327 are used to cooperate with the locking boss 1234 and the gas sampling pipe joint 12 to fix the gas pipe 11 on the first pipe inlet 122; wherein, the gas pipe 11 passes through the through hole 131, and the gas pipe 11 is sleeved in the first inverted member 121 and the first pipe inlet 122, and the joint lock 13 abuts against the locking boss 1234, and the joint lock 13 is rotated to screw the plurality of screw members 1327 into the locking boss 1234, and the locking boss 1234 and the gas sampling pipe joint 12 are ultrasonically measured by the first ultrasonic line. Acoustic welding provides double locking for the fixation of the gas pipe 11, ensuring that the gas pipe 11 will not loosen or leak during use, while improving the reliability and efficiency of the assembly process and increasing the service life of the equipment. At the same time, through this mechanical connection method, the entire assembly process does not require the use of chemical adhesives. After assembly is completed, the gas sampling tube 10 has good sealing properties to avoid gas leakage, which not only simplifies the production process, but also significantly improves the safety and reliability of the product. The gas sampling tube 10 uses a mechanical connection method instead of the traditional glue curing process, which fundamentally avoids the release of volatile organic substances and improves the safety of the gas sampling tube 10. At the same time, the use of a mechanical connection process does not require air drying and curing time, shortens the manufacturing time of the gas sampling tube 10, and improves the production capacity of the gas sampling tube 10.

[0067] In some embodiments, the outer surface of the first sleeve 124 is provided with a plurality of anti-slip protrusions, and the plurality of anti-slip protrusions are arranged at intervals, thereby increasing the friction of the gas sampling tube connector 12, helping to reduce the assembly time of the gas sampling tube 10 and the respiratory therapy equipment, further shortening the manufacturing time of the respiratory therapy equipment, and improving the production capacity of the respiratory therapy equipment.

[0068] In some embodiments, the inner surface of the first socket 124 is provided with threads, and the threads are used for threaded connection with the respiratory therapy device, thereby increasing the airtightness of the gas sampling tube connector 12 and the respiratory therapy device. At the same time, it also helps to reduce the assembly time of the gas sampling tube 10 and the respiratory therapy device, further shortening the manufacturing time of the respiratory therapy device, and improving the production capacity of the respiratory therapy device.

[0069] Please refer to Figures 8 to 10In some embodiments, the gas sampling pipe joint has a second inverted fastener 125, a second pipe entry 126 and a second sleeve 127; the second inverted fastener 125, the second pipe entry 126 and the second sleeve 127 are arranged in sequence from top to bottom; the second sleeve 127 is used to be sleeved on the respiratory therapy device, and the second pipe entry 126 is detachably connected to the gas pipe; the locking member 14 is configured as an embracing lock 141, and the embracing lock 141 is sequentially provided with a first embracing member 1411, a second embracing member 1412 and a deformation connection portion 1413, The first embracing member 1411 and the second embracing member 1412 can be embracing each other. The first embracing member 1411 and the second embracing member 1412 are both provided with a semicircular groove 1414, the shape of which is adapted to the gas pipe. The deformable connection portion 1413 is used to rotationally connect the first embracing member 1411 and the second embracing member 1412. The embracing lock 141 is used to fix the gas pipe in the first inverted fastener and the first pipe entry, thereby no longer relying on the traditional glue curing process, solving the problem of volatile organic compound release caused by glue volatilization. Through the cooperation of the first inverted fastener and the first pipe entry with the embracing lock 141, the gas pipe can achieve a stable mechanical connection, improving the reliability and airtightness of the assembly of the gas pipe and the gas sampling pipe joint, while avoiding the problem of loose connection caused by incomplete glue curing or glue aging.

[0070] Please refer to Figure 11 In some embodiments, the deformable connection portion 1413 includes a first connection portion 1415, a deformable body 1416, and a second connection portion 1417. The first connection portion 1415 is fixedly connected to the first engaging member 1411, and the second connection portion 1417 is fixedly connected to the second engaging member 1412. Both the first connection portion 1415 and the second connection portion 1417 are rotatably connected to the deformable body 1416. This facilitates rotation of the first and second engaging members 1411, 1412 during assembly and disassembly of the gas pipe, reducing assembly difficulty and improving assembly efficiency. This also prevents damage to the gas pipe caused by excessive stress during assembly, thereby extending the service life of the gas sampling pipe.

[0071] Please refer to Figure 11In some embodiments, bending grooves 1418 are defined at the pivotal connections between the first and second connecting portions 1415, 1417, and the deformable body 1416. This helps enhance the flexibility and precision of the first and second engaging members 1411, 1412 during rotation, allowing them to deform more smoothly during assembly or disassembly, reducing the risk of damage to the engaging lock 141 due to uneven deformation or concentrated stress. This significantly improves the overall assembly quality and stability of the gas sampling tube.

[0072] Please refer to Figure 10 In some embodiments, the first engaging member 1411 is provided with an engaging protrusion 1419, and the second engaging member 1412 is provided with an engaging buckle 1420. When the semicircular groove 1414 of the first engaging member 1411 is in contact with the gas pipe, the second engaging member 1412 is rotated to snap the engaging buckle 1420 into the engaging protrusion 1419, thereby ensuring that the gas pipe is securely fixed to the inverted fastener and the pipe entry member during the rotation of the second engaging member 1412. The snapping of the engaging buckle 1420 into the engaging protrusion 1419 effectively prevents the gas pipe from loosening or falling off during use, ensuring the continuity and accuracy of gas sampling. This achieves a secure and reliable mechanical connection without the use of glue, further eliminating the need for traditional glue curing processes and addressing the issue of volatile organic compound release caused by glue volatilization.

[0073] Please refer to Figure 12 and Figure 13 In some embodiments, a second ultrasonic line 1421 is provided on the outer side surface corresponding to the first embracing piece 1411 and the second embracing piece 1412. The second ultrasonic line 1421 is used for ultrasonic welding the first embracing piece 1411 and the second embracing piece 1412, thereby further enhancing the connection strength between the first embracing piece 1411 and the second embracing piece 1412, ensuring the sealing and firmness of the connection between the first embracing piece 1411 and the second embracing piece 1412, and ensuring the durability and safety of the gas sampling tube under high-frequency use conditions.

[0074] The second embodiment of the present application provides a respiratory therapy device, which includes a glue-free and chemical solvent-free gas sampling tube as described above, thereby greatly improving the airtightness and welding quality between the gas sampling tube connector and the connector lock, avoiding the loosening problem that may be caused by traditional glue connection, abandoning the process of using glue for curing, eliminating the safety risks caused by the volatilization of volatile organic substances, ensuring the safety of the user, and requiring no air drying and curing time, shortening the manufacturing time and cost of the respiratory therapy device, and improving the production capacity of the respiratory therapy device.

[0075] In summary, the present application provides a glue-free and chemical solvent-free gas sampling tube and respiratory therapy equipment, wherein the gas sampling tube includes: a gas pipe; a gas sampling tube connector, wherein the gas pipe is arranged on the gas sampling tube connector; a fastener, wherein the fastener is used to fix the gas pipe to the gas sampling tube connector.
