[0026] like Figures 1 to 6As shown, a circular single-path air connector includes a male connector 2 and a female connector 1. The female connector 1 includes a female housing 11 and a first air passage 12 provided in the female housing 11, and the male connector 2 includes a male housing 21 and a second air passage 22 provided in the male housing 21. In this embodiment, the front end of the male housing 21 is provided with a docking port 23 for accommodating the front end of the female housing 11, and a locking mechanism 3 is provided between the male connector 2 and the female connector 1. The locking mechanism 3 includes a mounting groove provided on the outer wall of the front end of the male housing 21. 31. A locking snap 32, an elastomer, a movable through hole 34 provided in the mounting groove 31 and penetrating the male housing 21 in the vertical plug-in and pull-out direction, and a locking ring groove 35 provided at the front end of the female housing 11 for cooperating with the locking snap 32 for locking. The locking snap 32 includes a locking portion 322 movably provided in the movable through hole 34 and a pressing portion 321 movably provided in the mounting groove 31. The elastomer is provided between the bottom of the mounting groove 31 and the locking portion 322, and can push the pressing portion 321 to drive the locking portion 322 to snap into the locking ring groove 35 to form a lock.

[0027] The single-air-circuit connector of this embodiment is circular in design. A docking port 23 is provided at the front end portion of the connector male end 2 housing, which can accommodate the front end insertion of the female end housing 11 and completely wrap the plug-in portion of the female end housing 11. The docking port 23 is connected to the second air passage 22 inside the male end housing 21, ensuring that when the female end housing 11 is inserted into the male end housing 21, the first air passage 12 inside the female end housing 11 can be correctly docked with the second air passage 22 inside the male end housing 21, thereby ensuring that the air passage is unobstructed. A locking mechanism 3 is provided to ensure the stability of the connection between the two. The locking mechanism 3 is composed of a mounting groove 31, a movable through hole 34, a locking snap 32, an elastic member, and a locking ring groove 35, and the locking snap 32 includes a pressing portion 321 and a locking portion 322. Specifically, the mounting slot 31 is a groove located on the outer wall on either side of the front end of the male housing 21, used to mount the locking snap 32 and the elastic member. Its shape is adapted to the pressing portion 321 of the locking snap 32, ensuring that the pressing portion 321 can move smoothly along it and leaving sufficient space for the elastic member to exert its elastic effect. The movable through hole 34 is a hole that passes through the front end of the male housing 21, with one end located at the bottom of the mounting slot 31 and arranged perpendicular to the insertion and removal direction. It allows the locking portion 322 to move along it, allowing it to cooperate with the locking ring groove 35 at the front end of the female housing 11 to achieve the locking function. The locking portion 322 of the locking snap 32 is integrally formed with the pressing portion 321 and extends from the bottom of the pressing portion 321. Its shape adapts to the cross-section of the male end 2 of the connector, and a socket for inserting the front end of the female end shell 11 is provided in the middle position; the locking ring groove 35 is circumferentially arranged at the front end position of the female end shell 11, and its specific position is the position corresponding to the movable through hole 34 when the female end shell 11 is inserted into the male end shell 21. At this time, the pressing portion 321 naturally sinks into the mounting groove 31, and the locking portion 322 adapts to fill the movable through hole 34, so that the female end 1 of the connector can be freely inserted and removed from the docking interface 23. In order to lock the male end 2 and the female end of the connector, an elastic member is provided between the bottom of the mounting groove 31 and the bottom of the pressing portion 321. The elastic member can provide the necessary elastic force to push the pressing portion 321 upward and drive the locking portion 322 to move upward. At this time, the bottom end of the locking portion 322 will move along the movable through hole 34 and fasten to the locking ring groove 35 of the female end housing 11, forming a lock. This can prevent the male end 2 and the female end of the connector from being blown apart by airflow when connected, and can withstand two atmospheres of pressure for a long time. When unlocking is required, force can be applied to press the pressing member to overcome the elastic force brought by the elastic body to drive the locking portion 322 to reset, disengage it from the locking ring groove 35 to complete the unlocking, which is simple and light. And because the locking groove arranged on the outer wall of the female end housing 11 is a ring groove, the female end housing 11 can be inserted into the male end housing 21 at any angle to establish a connection and can be locked.

[0028] like Figure 2 as well as Figure 6 As shown, the elastic body of this embodiment is a spring 33, and a guide post 311 is provided at the bottom of the mounting groove 31. One end of the spring 33 is mounted on the guide post 311, and a clamping groove 3211 is provided at the bottom of the pressing portion 321. The other end of the spring 33 is fixedly located in the clamping groove 3211. Specifically, a clamping groove 3211 is formed at the center of the bottom of the pressing portion 321. Its size is adapted to the spring 33, allowing the spring 33 to be clamped within the groove. The clamping groove 3211 cooperates with the guide post 311 provided at the bottom of the mounting groove 31 to limit the position of the spring 33, preventing it from deflecting or moving laterally under external forces, and ensuring that the elastic force of the spring 33 can be stably and effectively transmitted to the pressing portion 321. The guide post 311 also serves to limit the pressing portion 321. When the pressing portion 321 is pressed, the guide post 311, which is of an appropriate height, can abut the pressing portion 321, preventing it from being excessively pressed downward.

[0029] like Figure 2 as well as Figure 3 As shown, a sealing groove 41 is circumferentially defined on the outer wall of the front end of the female housing 11 of this embodiment, and a sealing ring 42 is disposed within the sealing groove 41. The sealing ring 42 is made of a material that is resistant to high temperatures, aging, and corrosion, and can effectively fill the small gap between the female housing 11 and the male housing 21, ensuring the sealing of the gas path and reducing the risk of gas leakage.

[0030] like Figure 1 As shown, the top of the pressing portion 321 of this embodiment is provided with multiple anti-slip grooves 5 for easier pressing. These grooves 5 increase the friction between the finger and the pressing portion 321, making the user's pressing more stable and less prone to slipping. Combined with the open mark on the top, it can indicate the unlocking position to the user, effectively improving operational convenience and reducing the possibility of misoperation.

[0031] Furthermore, the male housing 21, female housing 11, and locking snap 32 of this embodiment are all made of polysulfone (PSU). Polysulfone (PSU) has excellent high-temperature resistance and can maintain stable mechanical properties and dimensional stability at higher temperatures, making it suitable for applications in high-temperature environments. The connector can also be sterilized at temperatures of 150°C. It also has excellent biocompatibility, meeting the strict standards of the medical industry and suitable for widespread use in medical devices.

[0032] In summary, the beneficial effects of this embodiment are as follows: this embodiment provides a locking mechanism 3 consisting of a mounting groove 31, a movable through hole 34, a locking snap 32, a spring 33, and a locking ring groove 35. The elastic force provided by the spring 33 is used to push the pressing portion 321 of the locking snap 32 upward and drive its locking portion 322 to move upward, so that the locking portion 322 moves along the movable through hole 34 and fastens to the locking ring groove 35 of the female housing 11, thereby forming a lock. This design can effectively prevent the male end 2 and the female end of the connector from being blown apart by airflow during connection, thereby ensuring the stability of the connection between the two. In addition, by applying force to press the pressing member, the elastic force of the spring 33 can be overcome, driving the locking portion 322 to reset, disengaging it from the locking ring groove 35, and completing the unlocking, which is simple and easy to operate. The locking groove is set as a ring groove, so that the female end 1 of the connector can be locked at any angle when inserted, which can be used for blind insertion and quick plugging and unplugging. A sealing groove 41 is circumferentially formed on the outer wall of the front end of the female housing 11, and a sealing ring 42 is provided in the sealing groove 41, which can effectively fill the small gap between the female housing 11 and the male housing 21 to ensure the sealing of the air path.

[0033] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
