[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0030] Reference Figure 1 , Figure 2 as well as Figure 3 This application provides a quick-opening connector, including a male end structure 1 and a female end structure 2. The male end structure 1 and the female end structure 2 are installed together. When the male end structure 1 and the female end structure 2 are installed, the male end structure 1 and the female end structure 2 will be connected to allow fluid to pass through.

[0031] Reference Figure 2 as well as Figure 3 Specifically, the male end structure 1 includes a male end housing 11, a male end valve body assembly 12 disposed on the male end housing 11, and a male end sealing ring 13. The male end housing 11 includes an upper male end housing and a lower male end housing, which are formed by planar ultrasonic welding. The male end housing 11 has a male end communicating cavity 112 inside, which extends along the length of the male end housing 11 and penetrates through the male end housing 11.

[0032] The male valve body assembly 12 includes a male shut-off valve body 121 and a male shut-off valve spring 122 disposed in the male connecting cavity 112. The male shut-off valve body 121 is slidably connected to the male housing 11. The male connecting cavity 112 has a male stepped hole. The male shut-off valve body 121 abuts against or disengages from the male stepped hole to close or open the male connecting cavity 112. One end of the male shut-off valve spring 122 is connected to the male shut-off valve body 121, and the other end of the male shut-off valve spring 122 is disposed in the male housing 11. In the initial state, the male shut-off valve will press against the male stepped hole under the action of the male shut-off valve spring 122, thereby closing one end of the male connecting cavity 112 and preventing liquid from passing through the male connecting cavity 112.

[0033] In this embodiment, to ensure the airtightness of the male end shut-off valve body 121, a male end valve core sealing ring 123 is fitted onto the male end shut-off valve body 121. The male end valve core sealing ring 123 abuts against or disengages from the male end stepped hole. In the initial state, the male end shut-off valve body 121 is tightly fitted between the male end stepped hole and the male end shut-off valve body 123 to further increase the airtightness and prevent liquid from passing through the male end connecting cavity 112.

[0034] To mate with the female end structure 2, one end of the male end housing 11 has a male end centering conical surface 111. The male end centering conical surface 111 is located on the outer peripheral surface of the male end housing 11, and its size gradually decreases from the end furthest from the male end stepped hole to the end closest to the male end stepped hole. With this arrangement, when the male end housing 11 mates with the female end structure 2, the male end centering conical surface 111 will engage with the female end structure 2 to provide guidance, thereby facilitating the installation of the male end housing 11.

[0035] The male end sealing ring 13 is sleeved and installed on the outer wall of the male end housing 11. In this embodiment, the male end sealing ring 13 is located at the end of the male end housing 11 near the male end stepped hole. When the male end housing 11 is installed into the female end structure 2, the male end sealing ring 13 will abut against the male end housing 11 and the female end structure 2 to increase the sealing performance.

[0036] Reference Figure 4 , Figure 5 as well as Figure 6 The female end structure 2 includes a female end housing 21, a female end valve body assembly 22 disposed on the female end housing 21, and a detection assembly 23. The female end housing 21 includes a female end upper housing and a female end lower housing, which are formed by planar ultrasonic welding. The female end housing 21 has a mounting cavity 211 and a female end connecting cavity 212 along its length direction. The mounting cavity 211 and the female end connecting cavity 212 penetrate the female end housing 21, and the female end connecting cavity 212 is located on the side of the mounting cavity 211 away from the male end connecting cavity 112.

[0037] To accommodate the installation of the male end structure 1, the inner wall of the mounting cavity 211 has an inclined female end centering conical surface 2111. The shape of the female end centering conical surface 2111 matches the shape of the male end centering conical surface 111. The male end housing 11 is installed in the mounting cavity 211 through the male end centering conical surface 111. The male end sealing ring 13 abuts against or disengages from the inner wall of the mounting cavity 211. With this arrangement, during the installation process, the two conical surfaces of the male end housing 11 can act as guides and automatically center, increasing the installation efficiency and accuracy of the male end structure 1 and the female end structure 2. At the same time, the male end sealing ring 13 ensures the airtightness of the male end housing 11 and the female end housing 21 after installation, preventing liquid leakage from the connection between the male end housing 11 and the female end housing 21.

[0038] The female valve body assembly 22 includes a female shut-off valve body 221 disposed in the female connecting cavity 212 and a female shut-off valve spring 222. The female shut-off valve body 221 is slidably connected to the female housing 21 and faces the male shut-off valve body 121. In this embodiment, the female connecting cavity 212 has a female stepped hole, and the female shut-off valve body 221 abuts against or disengages from the female stepped hole to close or open the female connecting cavity 212. A female valve core sealing ring 223 is sleeved on the female shut-off valve body 221, and the female valve core sealing ring 223 abuts against or disengages from the female stepped hole. One end of the female shut-off valve spring 222 is connected to the female shut-off valve body 221, and the other end of the female shut-off valve spring 222 is disposed in the female housing 21.

[0039] Reference Figure 4 , Figure 5 , Figure 6 as well as Figure 7 In the initial state, under the action of the female end stop spring, the female end stop valve body 221 will press against the female end stepped hole to isolate the installation cavity 211 and the female end connecting cavity 212. At this time, the female end valve core sealing ring 223 presses against the female end stepped hole to further increase the sealing performance. In the installation state, the male end stop valve body 121 and the female end stop valve body 221 will press against each other and apply force, so that the male end stop valve body 121 moves away from the male end stepped hole and the female end stop valve body 221 moves away from the female end stepped hole, so as to realize the conduction of the male end connecting cavity 112 and the female end connecting cavity 212.

[0040] The detection component 23 is located on one side of the mounting cavity 211 and faces the other side of the mounting cavity 211. The detection component 23 is used to detect the installation status of the male end structure 1 and the female end structure 2. Specifically, the detection component 23 includes an infrared emitting tube 231 disposed on one side of the mounting cavity 211 and an infrared receiving tube 232 disposed on the other side of the mounting cavity 211. Both the infrared emitting tube 231 and the infrared receiving tube 232 are connected to an external power supply device.

[0041] Infrared emitter 231 faces infrared receiver 232. Infrared emitter 231 contains an infrared light source; when current flows through it, it emits infrared light. Infrared receiver 232 faces infrared emitter 231 and includes an infrared receiver and a collector. When an object approaches the light beam, the light is reflected or scattered by the object. The presence of the object is determined by detecting the reflected or scattered infrared light and its intensity changes. An electrical signal is then generated and output to the collector. This signal can be processed to determine the installation status of male terminal structure 1 and female terminal structure 2. Infrared emitter 231 and infrared receiver 232 are existing technologies and can be purchased; their specific structure and principles will not be described further.

[0042] By configuring the detection component 23 in this way, and using a preset light-blocking threshold after the male and female structures are fully installed as a standard range, the system checks whether the light-blocking threshold reaches the standard range during each installation process. The threshold is converted by a signal transmission board and displayed on an external digital display screen, allowing for real-time monitoring of whether the connector is fully installed, thus ensuring the assembly quality of the connector. It is understandable that the detection component 23 can also monitor the installation status of the male and female structure 2 using capacitive or photosensitive sensing methods, and can be adjusted as needed.

[0043] In addition, the female end structure 2 also includes an auxiliary button 24 disposed on the female end housing 21. The auxiliary button 24 is connected to an auxiliary alignment spring ring 241, which is fitted and slidably connected to the inner wall of the mounting cavity 211. The axis of the auxiliary alignment spring ring 241 coincides with or is misaligned with the axis of the mounting cavity 211. The auxiliary button 24 and the auxiliary alignment spring ring 241 are integrally formed. In this embodiment, the auxiliary button 24 and the auxiliary alignment spring ring 241 are located at the female end centering cone surface 2111. By setting the auxiliary button 24 and the auxiliary alignment spring ring 241, pressing the auxiliary button 24 can drive the auxiliary alignment spring ring 241 to move, thereby causing the auxiliary alignment spring ring 241 to drive the male end housing 11 to move for further alignment. In the initial state, the axis of the auxiliary alignment spring ring 241 is misaligned with the axis of the mounting cavity 211. After the male end housing 11 is installed, the alignment spring ring is driven by pressing the auxiliary button 24, and the male end housing 11 is continuously installed by applying force. The auxiliary button 24 can drive the male end housing 11 to be aligned, thereby ensuring the accuracy of the assembly.

[0044] Exemplary embodiments of this disclosure have been specifically shown and described above. It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementations described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
