Description

Technical Field

[0001] This application relates to the field of connector technology, specifically to a fluid connector and a liquid cooling device. Background Technology

[0002] The liquid piping system includes a first pipe, a second pipe, and a fluid connector. The fluid connector includes a first joint and a second joint. The first joint connects to the first pipe, and the second joint connects to the second pipe. The connection between the first joint and the second joint is detachable to facilitate connection or disconnection between the first and second pipes. However, the assembly and disassembly of the first and second joints usually require manual operation, which is difficult in confined or poorly visible spaces. Summary of the Invention

[0003] This application provides a fluid connector and a liquid cooling device, which can reduce the difficulty of disassembling and assembling the first connector and the second connector.

[0004] In a first aspect, embodiments of this application provide a fluid connector, including a first connector and a second connector. The first connector includes a first tube body, an annular flange sealing structure, and a first valve core. The first valve core is disposed within the first tube body and connected to the first tube body via the annular flange sealing structure. The second connector includes a second tube body, a sleeve sealing structure, and a second valve core. The second valve core is disposed within the second tube body and connected to the second tube body via the sleeve sealing structure.

[0005] The fluid connector also includes a locking sleeve, which is fitted over the first tube body and rotatably connected to it. The locking sleeve is connected to the second connector via a drive structure, which drives the locking sleeve to rotate in a first direction when the first tube body moves relative to the second tube body in a direction parallel to the axial centerline. The locking sleeve has a first locking part, and the second tube body has a second locking part.

[0006] During the locking process, the first tube body passes through the second tube body, the first valve core contacts the second valve core, and the annular flange contacts the sleeve to achieve communication between the first and second tube bodies. The driving structure drives the locking sleeve to rotate to the locking position, so that the first locking part and the second locking part are locked, preventing the first tube body from moving relative to the second tube body along the axial centerline direction.

[0007] During the unlocking process, the first tube moves into the second tube, and the driving structure drives the locking sleeve to rotate to the unlock position so that the first locking part and the second locking part are unlocked. The first tube moves relative to the second tube along the axial center line until the first connector and the second connector are separated.

[0008] The fluid connector provided in this application includes a locking sleeve, which is connected to a second tube body via a driving structure. The driving structure can drive the locking sleeve to rotate. Since the locking sleeve is provided with a first locking part and the second tube body is provided with a second locking part, the driving structure can change the relative position of the first locking part and the second locking part by driving the locking sleeve to rotate, so that the first locking part and the second locking part can be locked or unlocked, thereby controlling the conduction or separation of the first connector and the second connector, and reducing the difficulty of disassembling and assembling the first connector and the second connector.

[0009] In some embodiments that may include the above embodiments, the driving structure includes a first driving structure and a second driving structure. The first driving structure is disposed on the locking sleeve, and the second driving structure is disposed on the second tube body. The first driving structure includes a driving block, and the end of the driving block facing the second driving structure has a first inclined surface.

[0010] The second driving structure includes a driving flange disposed on the outer periphery of the second tube body, and a plurality of driving grooves disposed on the driving flange, the driving grooves being arranged around the axial centerline of the second tube body. The driving grooves include intersecting first groove walls and second groove walls, the first groove wall being used to contact the first inclined surface to drive the locking sleeve to rotate.

[0011] The first driving structure includes a driving block, and the end of the driving block facing the second driving structure has a first inclined surface. The second driving structure includes a driving flange, and a driving groove is provided on the driving flange. The driving groove includes a first groove wall. When the first groove wall contacts the first inclined surface, the first groove wall will generate an oblique force on the first inclined surface, causing the first inclined surface to move along the first groove wall toward the bottom of the driving groove, thereby causing the locking sleeve to rotate.

[0012] In some embodiments that may include the above embodiments, the drive block includes a plurality of drive blocks, which are spaced apart around the axial center line of the first tube body.

[0013] Multiple drive blocks are spaced apart around the axial center line of the first tube body, which ensures that there is always a drive block and a drive groove matching during the rotation of the locking sleeve, so that the locking sleeve can continue to rotate and realize the locking or unlocking of the first and second connectors.

[0014] In some embodiments that may include the above embodiments, the second locking part includes a locking protrusion disposed on the outer wall of the second tube body, and a channel for the locking protrusion to pass through is provided between adjacent driving blocks. The first locking part includes a locking groove disposed at one end of the driving block opposite to the first inclined surface. The locking groove includes a guide wall and a locking wall. The locking wall is disposed parallel to the axial centerline of the first tube body, and the guide wall is disposed inclined relative to the locking wall.

[0015] During the locking process, the first and second tubes approach each other, and the first groove wall contacts the first inclined surface to drive the locking sleeve to rotate. The locking protrusion rotates into the locking groove and contacts the guide wall to drive the locking sleeve to rotate, so that the first inclined surface contacts the first groove wall of the next driving groove. In the locked position, the locking wall contacts the locking protrusion.

[0016] During the unlocking process, the first and second tubes move closer together, and the first inclined surface contacts the first groove wall of the next drive groove, driving the locking sleeve to rotate, causing the locking protrusion to rotate into the groove. In the unlocked position, the first inclined surface contacts the bottom of the drive groove.

[0017] There is a channel between adjacent drive blocks for the locking protrusion to pass through. The second locking part includes a locking protrusion provided on the outer wall of the second tube. The first locking part includes a locking groove provided at one end of the drive block away from the first inclined surface. The locking protrusion can cooperate with the locking groove to lock the first connector and the second connector. The channel can guide the locking protrusion to move to the vicinity of the locking groove.

[0018] The locking groove includes a guide wall and a locking wall. The locking wall is parallel to the axial centerline of the first tube, while the guide wall is inclined relative to the locking wall. The locking wall prevents the locking protrusion from moving, ensuring that the locking protrusion is ultimately fixed at the bottom of the locking groove. The inclined arrangement of the guide wall relative to the locking wall ensures that when there is a positional deviation between the locking protrusion and the bottom of the locking groove, the locking protrusion contacts the guide wall, causing the locking sleeve to rotate. The locking protrusion then moves along the guide wall relative to the locking sleeve to the bottom of the locking groove, ensuring that the first and second connectors can be locked.

[0019] In some embodiments that may include the above embodiments, the drive block further includes a guide surface, which is inclined relative to the locking wall and disposed on the side of the locking wall away from the guide wall. The guide surface is connected to the locking wall and the channel respectively.

[0020] The guide surface is inclined relative to the locking wall and is located on the side of the locking wall away from the guide wall, and is connected to both the locking wall and the channel. During the unlocking process, when there is a positional deviation between the locking protrusion and the channel opening, the guide surface contacts the locking protrusion, causing the locking protrusion to move relative to the guide surface towards the channel opening, thereby ensuring that the locking protrusion can enter the channel and unlock the first and second connectors.

[0021] In some embodiments that may include the above embodiments, the end of the drive block facing the second drive structure has a second inclined surface, the first inclined surface and the second inclined surface intersect, and the second inclined surface is used to contact the second groove wall to drive the locking sleeve to rotate.

[0022] The drive block has a second inclined surface that intersects with the first inclined surface and contacts the second groove wall, which can drive the locking sleeve to rotate. Because the second inclined surface and the second groove wall are in contact, the locking sleeve can be driven to rotate. The locking and unlocking of the first connector and the second connector can be achieved through the contact between the second inclined surface and the second groove wall, thereby reducing the positional accuracy requirements of the first inclined surface and the first groove wall and reducing the manufacturing difficulty of the drive block and the drive flange.

[0023] In some embodiments that may include the above embodiments, the first locking part includes multiple parts, each corresponding to a drive block, and the second locking part includes multiple parts, which are spaced apart around the axial center line of the second tube body.

[0024] The first locking part includes multiple parts, each corresponding to a drive block. Multiple second locking parts are spaced apart around the axial center line of the second tube body, which can ensure that there are always first and second locking parts matching during the rotation of the locking sleeve, thus ensuring the locking of the first connector and the second connector.

[0025] In some embodiments that may include the above embodiments, the first sealing structure includes an annular flange, which is sleeved on the outside of the first valve core and is sealed to the pipe wall of the first valve core and the first pipe body, respectively.

[0026] The annular flange is sealed to the walls of the first valve core and the first pipe body, respectively, which ensures that the first pipe body is sealed when the first connector is not connected to the second connector, thus preventing liquid leakage from the first pipe body.

[0027] In some embodiments that may include the above embodiments, the second sealing structure includes a sleeve that is sleeved outside the second valve core and is sealed to the walls of the second valve core and the second pipe body, respectively. The second valve core is configured to be movable along the axial centerline of the second pipe body.

[0028] The sleeve is sealed to the walls of the second valve core and the second pipe body respectively, which can ensure that the second pipe body is in a sealed state when the second connector is not connected to the first connector, thus preventing liquid leakage from the second pipe body.

[0029] In some embodiments that may include the above embodiments, the first connector further includes a first elastic element, which is connected to the first tube body and the first valve core respectively. The first elastic element is used to make the end face of the first valve core near the second connector coplanar with the end face of the first sealing structure near the second connector, so as to seal the first tube body.

[0030] During the locking process, the first valve core and the second valve core come into contact. The first valve core moves away from the second tube relative to the first tube body. At this time, the first elastic element is compressed and undergoes elastic deformation. During the unlocking process, the first valve core and the second valve core separate. The first elastic element applies a force resisting the elastic deformation to the bottom wall of the first tube body, pushing the first tube body until the end face of the first valve core near the second connector is coplanar with the end face of the first sealing structure near the second connector, thus sealing the first tube body.

[0031] In some embodiments that may include the above embodiments, the second connector further includes a second elastic element, which is connected to the second tube body and the second sealing structure respectively. The second elastic element is used to make the end face of the second sealing structure near the first connector coplanar with the end face of the second valve core near the first connector, so as to seal the second tube body.

[0032] During the locking process, the first and second sealing structures come into contact, and the second sealing structure moves away from the first tube relative to the first sealing structure. At this time, the second elastic element is compressed and undergoes elastic deformation. During the unlocking process, the first and second sealing structures separate, and the second elastic element applies a force resisting the elastic deformation to the second sealing structure, pushing the second sealing structure until the end face of the second sealing structure near the first connector is coplanar with the end face of the second valve core near the first connector, thus sealing the second tube.

[0033] In some embodiments that may include the above embodiments, the second connector includes a guide channel disposed at one end of the second tube body near the first tube body. The guide channel includes a first end face and a second end face, the first end face being closer to the first tube body than the second end face, the second end face being connected to the second tube body, and the area of ​​the first end face being larger than the area of ​​the second end face.

[0034] The first end face is closer to the first connector than the second end face, and the area of ​​the first end face is larger than the area of ​​the second end face. When the axial center line of the first tube body and the axial center line of the second tube body do not coincide, the first tube body can move along the side wall of the guide channel so that the axial center line of the first tube body coincides with the axial center line of the second tube body, thereby allowing the first tube body to pass through the second tube body and realize the connection between the first connector and the second connector.

[0035] In some embodiments that may include the above embodiments, the first tube body further includes a groove disposed on the outer periphery of the first tube body, the groove being disposed around the axial center line of the first tube body. The locking sleeve further includes a locking structure disposed on the outer periphery of the locking sleeve, the locking structure being disposed around the axial center line of the first tube body, and the locking structure matching the groove.

[0036] The locking structure and groove match to achieve the connection between the first tube body and the locking sleeve, preventing the locking sleeve from moving along the axial direction of the first tube body, while ensuring that the locking sleeve can rotate along the circumferential direction of the first tube body, thus realizing the rotatable connection between the first tube body and the locking sleeve.

[0037] Secondly, embodiments of this application provide a liquid cooling device, including a liquid cooling channel, a liquid cooling pipeline, and the aforementioned fluid connector. The liquid cooling channel and the liquid cooling pipeline are connected through the fluid connector, and the liquid cooling channel is used to dissipate heat from the components in the liquid cooling device.

[0038] The liquid cooling device provided in this application includes the fluid connector in any of the above embodiments, so both can solve the same technical problem and achieve the same technical effect. Attached Figure Description

Detailed Implementation

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0057] Furthermore, in the embodiments of this application, directional terms such as "up," "down," "left," "right," "horizontal," and "vertical" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0058] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0059] It should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection or an integral connection; they can also refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0060] Please refer to Figure 1 The liquid piping system 10 allows liquid to flow from one system to another. This application embodiment does not limit the type of liquid used; for example, the liquid can be water, petroleum, or coolant. The liquid piping system 10 includes a first pipe 11, a second pipe 12, and a fluid connector 20. The fluid connector 20 includes a first joint 21 and a second joint 22, which are detachably connected. The first joint 21 is connected to the first pipe 11, and the second joint 22 is connected to the second pipe 12. The first pipe 11 and the second pipe 12 are respectively connected to their respective systems.

[0061] When the fluid connector 20 is in the conducting state, the first connector 21 and the second connector 22 are connected, the first conduit 11 and the second conduit 12 are connected, and liquid can flow from one system to another. Liquid in the first conduit 11 can flow into the second conduit 12, and liquid in the second conduit 12 can flow into the first conduit 11. When the fluid connector 20 is in the closed state, the first connector 21 and the second connector 22 are disconnected, the first conduit 11 and the second conduit 12 are not connected, the first conduit 11 is sealed, and the second conduit 12 is sealed.

[0062] Please refer to Figure 2 , Figure 2 The dashed line represents the flow path of hot water, and the solid line represents the flow path of cold water. In embodiments where the liquid is a coolant, the liquid piping system 10 can be used for the cooling system 1. Servers and similar devices typically require the cooling system 1 for heat dissipation. The cooling system 1 includes a cooling device 3 and a cooling capacity distribution unit 4, which is connected to both the cooling device 3 and the liquid cooling plate 5 within the server 2. The second coolant within the liquid cooling plate 5 can cool the server 2, but simultaneously, the temperature of the second coolant rises, rendering it unable to continue operating. The cooling capacity distribution unit 4 can use the first coolant from the cooling device 3 to cool the second coolant within the liquid cooling plate 5, thereby achieving cooling of the server 2.

[0063] The cooling capacity distribution unit 4 and the cooling device 3 can be connected via two fluid connectors 20. When the fluid connectors 20 are in the conductive state, one of the fluid connectors 20 allows the first coolant in the cooling device 3 to enter the cooling capacity distribution unit 4 and participate in cooling. After participating in cooling, the temperature of the first coolant rises. The heated first coolant can flow back from the cooling capacity distribution unit 4 to the cooling device 3 through the other fluid connector 20. The cooling device 3 can then cool the heated first coolant, allowing it to be used to continue cooling the second coolant.

[0064] The cooling distribution unit 4 and the liquid cooling plate 5 can also be connected via two fluid connectors 20. When the fluid connectors 20 are in the conductive state, one of the fluid connectors 20 allows the second coolant in the liquid cooling plate 5 to enter the cooling distribution unit 4 and exchange heat with the first coolant. The cooled second coolant can then flow back to the liquid cooling plate 5 through the other fluid connector 20 to continue cooling the server 2.

[0065] This application provides a liquid cooling device, including a liquid cooling channel, a liquid cooling pipeline, and a fluid connector 20. The liquid cooling channel and the liquid cooling pipeline are connected through the fluid connector 20. The liquid cooling channel is used to dissipate heat from the components in the liquid cooling device. This application does not limit the liquid cooling device; for example, the liquid cooling device may include energy storage devices, servers, etc.

[0066] In an embodiment where the liquid cooling device includes an energy storage device, the liquid cooling channel is the liquid cooling channel inside the liquid cooling plate of the battery pack. The liquid cooling channel is connected to one end of the liquid cooling pipeline through a fluid connector, and the other end of the liquid cooling pipeline can be connected to the cooling device 3, so that the coolant in the cooling device 3 enters the liquid cooling channel to dissipate heat from the battery pack.

[0067] In an embodiment where the liquid cooling device includes the server 2, the liquid cooling device includes a cooling capacity distribution device and a liquid cooling plate 5. The cooling capacity distribution device includes multiple cooling capacity distribution units 4 and multiple fluid connectors 20. Each cooling capacity distribution unit 4 is detachably connected to the cooling device 3 and the liquid cooling plate 5 via a fluid connector 20. The cooling capacity distribution unit 4 is used for heat exchange between a first coolant and a second coolant. The fluid connector 20 is used to prevent the first coolant and the second coolant from flowing out in the detached state. The first coolant comes from the cooling device 3, and the second coolant comes from the liquid cooling plate 5.

[0068] It is understandable that the liquid cooling channel is the pipeline within the cooling capacity distribution unit 4, the liquid cooling pipeline is the pipeline connected to the cooling device 3 or the liquid cooling plate 5, and is used to realize the transmission of the first coolant and the second coolant. The components in the liquid cooling device are the components in the server 2 that are in contact with the liquid cooling plate 5.

[0069] Please refer to Figure 3 and Figure 4 , Figure 3 This is a structural diagram showing the fluid connector 20 when it is conductive (the first connector 21 and the second connector 22 are connected). Figure 4 for Figure 3 A cross-sectional view. This embodiment provides a fluid connector 20, including a first connector 21 and a second connector 22.

[0070] Please refer to Figure 5 and Figure 6 , Figure 5 This is an overall structural diagram of the first connector 21. Figure 6 for Figure 5 A cross-sectional view. The first connector 21 includes a first tube body 31, a first sealing structure 32, and a first valve core 33. The first valve core 33 is disposed inside the first tube body 31 and is connected to the first tube body 31 through the first sealing structure 32.

[0071] The first valve core 33 can move along the axial centerline of the first pipe body 31. The first sealing structure 32 is connected to the first pipe body 31, and its position is fixed. It is understood that the first pipe body 31 is a hollow cylinder, and the end of the first pipe body 31 away from the second connector 22 is the pipe connection end, used to connect to the first pipe 11. This application embodiment does not limit the connection method between the pipe connection end and the first pipe 11; for example, threads, chucks, clamps, etc., can be used. The shape of the first valve core 33 can be a cylinder, a cone, etc. This application embodiment does not limit the shapes of the first valve core 33 and the first sealing structure 32, as long as the shapes of the first valve core 33 and the first sealing structure 32 match, thereby ensuring that the first valve core 33 and the first sealing structure 32 can seal the opening of the first pipe body 31 and prevent liquid leakage.

[0072] In some embodiments, a groove is provided on the outer periphery of the first valve core 33, and a sealing ring is disposed in the groove, which can enhance the sealing between the first valve core 33 and the first sealing structure 32.

[0073] In the above embodiment, the first sealing structure 32 includes an annular flange 61, which is sleeved on the outside of the first valve core 33. The annular flange 61 is sealed to the walls of the first valve core 33 and the first tube body 31, respectively. It can be understood that the annular flange 61 is a protrusion on the inner wall of the first tube body 31 near the second connector 22, and the thickness of the annular flange 61 is greater than the thickness of the rest of the first tube body 31.

[0074] It is understandable that the annular flange 61 is sealed to the walls of the first valve core 33 and the first tube body 31 respectively, which can ensure that the first tube body 31 is in a sealed state when the first connector 21 is not connected to the second connector 22, and the liquid is sealed in the first connector 21 to prevent liquid leakage.

[0075] In the above embodiment, the first connector 21 further includes a first elastic element 37, which is connected to the first tube body 31 and the first valve core 33 respectively. The first elastic element 37 is used to make the end face of the first valve core 33 near the second connector 22 coplanar with the end face of the first sealing structure 32 near the second connector 22, so as to seal the first tube body 31.

[0076] The first elastic element 37 is connected to the first tube body 31 and the first valve core 33 respectively. The first elastic element 37 is used to make the end face of the first valve core 33 near the second connector 22 coplanar with the end face of the first sealing structure 32 near the second connector 22, so as to seal the first tube body 31. That is, the first elastic element 37 is disposed inside the first tube body 31, located between the bottom wall of the first tube body 31 and the first valve core 33.

[0077] Please refer to Figure 7 and Figure 8 , Figure 7 This is a structural diagram of the second connector 22. Figure 8 for Figure 7 A cross-sectional view. The second connector 22 includes a second tube body 34, a second sealing structure 35, and a second valve core 36. The second valve core 36 is disposed inside the second tube body 34 and is connected to the second tube body 34 through the second sealing structure 35.

[0078] The second sealing structure 35 can move along the axial centerline of the second pipe body 34. The second valve core 36 is connected to the second pipe body 34, and the position of the second valve core 36 is fixed. It is understood that the second pipe body 34 is a hollow cylinder, and the cross-sectional area of ​​the second pipe body 34 is larger than that of the first pipe body 31, allowing the first pipe body 31 to pass through the second pipe body 34. The end of the second pipe body 34 furthest from the first connector 21 is the pipe connection end, used to connect to the second pipe 12. This application embodiment does not limit the connection method between the pipe connection end and the second pipe 12; for example, threads, chucks, clamps, etc., can be used.

[0079] The shape of the second valve core 36 can be a cylinder, a cone, etc. In this embodiment, the shape of the second valve core 36 and the second sealing structure 35 is not limited, as long as the shapes of the second valve core 36 and the second sealing structure 35 match, so that the second valve core 36 and the second sealing structure 35 can seal the opening of the second pipe body 34 and prevent liquid leakage.

[0080] In some embodiments, a groove is provided on the outer periphery of the second valve core 36, and a sealing ring is disposed in the groove, which can enhance the sealing performance between the second valve core 36 and the second sealing structure 35.

[0081] In the above embodiment, the second sealing structure 35 includes a sleeve 62, which is sleeved outside the second valve core 36. The sleeve 62 is sealed to the walls of the second valve core 36 and the second tube body 34, respectively. The sleeve 62 is configured to move along the axial centerline of the second tube body 34. It is understood that the length of the sleeve 62 along the axial centerline of the second tube body 34 is less than the length of the second tube body 34. This ensures that the sleeve 62 and the second valve core 36 can seal the second tube body 34, while avoiding the sleeve 62 being too long and affecting the formation of the flow channel between the first tube body 31 and the second tube body 34.

[0082] It is understandable that the sleeve 62 is sealed to the walls of the second valve core 36 and the second pipe body 34 respectively, which can ensure that the second pipe body 34 is in a sealed state when the second connector 22 is not connected to the first connector 21, and the liquid is sealed in the second connector 22 to prevent liquid leakage.

[0083] In the above embodiment, the second connector 22 further includes a second elastic element 38, which is connected to the second tube body 34 and the second sealing structure 35 respectively. The second elastic element 38 is used to make the end face of the second sealing structure 35 near the first connector 21 coplanar with the end face of the second valve core 36 near the first connector 21, so as to seal the second tube body 34.

[0084] The second elastic element 38 is connected to the second tube body 34 and the second valve core 36 respectively. The second elastic element 38 is used to make the end face of the second sealing structure 35 near the first connector 21 coplanar with the end face of the second valve core 36 near the first connector 21, so as to seal the second tube body 34. That is, the second elastic element 38 is disposed inside the second tube body 34, located between the bottom wall of the second tube body 34 and the second sealing structure 35.

[0085] Please refer to Figure 9 , Figure 9 This diagram illustrates the process of locking the first connector 21 and the second connector 22 internally. During the locking process, the first tube 31 passes through the second tube 34, the first valve core 33 contacts the second valve core 36, and the first sealing structure 32 contacts the second sealing structure 35, thereby achieving communication between the first tube 31 and the second tube 34.

[0086] At this time, since the first valve core 33 can move along the axial centerline and the position of the second valve core 36 is fixed, when the first tube 31 moves towards the second tube 34, the first valve core 33 is held in place by the second valve core 36 and moves away from the second tube 34 relative to the first tube 31. As the first tube 31 moves, the bottom wall of the first tube 31 moves towards the second tube 34, and the position of the first valve core 33 remains unchanged. The first elastic element 37 is compressed and undergoes elastic deformation.

[0087] Since the second sealing structure 35 can move along the axial centerline, while the position of the first sealing structure 32 is fixed, when the first tube 31 moves toward the second tube 34, the second sealing structure 35 is pushed by the first sealing structure 32 and moves away from the first tube 31 relative to the second tube 34. As the first tube 31 moves, the first sealing structure 32 moves toward the second tube 34, while the position of the bottom wall of the second tube 34 remains unchanged. The second elastic element 38 is compressed and undergoes elastic deformation.

[0088] At this time, the first tube 31 and the second tube 34 are connected, and a flow channel is formed inside the first tube 31 and the second tube 34, allowing the liquid to flow through the flow channel.

[0089] Please refer to Figure 10 , Figure 10 This diagram illustrates the unlocking process of the first connector 21 and the second connector 22. During the unlocking process, the first elastic element 37 applies a force resisting elastic deformation to the bottom wall of the first valve core 33 and the first tube body 31, causing the first tube body 31 to move away from the second tube body 34. This makes the end face of the first valve core 33 near the second connector 22 coplanar with the end face of the first sealing structure 32 near the second connector 22, thereby closing the first tube body 31.

[0090] The second elastic element 38 will apply the force resisting elastic deformation to the bottom wall of the second sealing structure 35 and the second tube 34, causing the second sealing structure 35 to move towards the first tube 31, so that the end face of the second sealing structure 35 near the first connector 21 is coplanar with the end face of the second valve core 36 near the first connector 21, thereby sealing the second tube 34.

[0091] It is understandable that during the locking and unlocking processes, the first tube 31 is initially inserted into the second tube 34, and the axial center line of the first tube 31 coincides with the axial center line of the second tube 34, referred to as the axial center line.

[0092] Continue to refer to Figure 3 and Figure 5 The fluid connector 20 also includes a locking sleeve 23, which is sleeved on the outside of the first tube body 31 and is rotatably connected to the first tube body 31. The rotatable connection means that the locking sleeve 23 can move around the circumference of the first tube body 31, but does not move along the axial direction of the first tube body 31.

[0093] Continue to refer to Figure 6 In the above embodiment, the first tube 31 further includes a groove 53 disposed on the outer periphery of the first tube 31, the groove 53 being disposed around the axial center line of the first tube 31. The locking sleeve 23 further includes a locking structure 54 disposed on the outer periphery of the locking sleeve 23, the locking structure 54 being disposed around the axial center line of the first tube 31, and the locking structure 54 matching the groove 53.

[0094] It is understandable that the locking structure 54 and the groove 53 match to realize the connection between the first tube 31 and the locking sleeve 23, prevent the locking sleeve 23 from moving along the axial direction of the first tube 31, and at the same time ensure that the locking sleeve 23 can rotate along the circumferential direction of the first tube 31, so as to realize the rotatable connection between the first tube 31 and the locking sleeve 23.

[0095] In some embodiments, a protrusion 55 is provided on the outer periphery of the first tube 31, and the protrusion 55 is located on the side of the groove 53 opposite to the locking structure 54. The protrusion 55 can increase the contact area between the first tube 31 and the locking structure 54, ensuring that the locking sleeve 23 cannot move along the axial direction of the first tube 31.

[0096] Continue to refer to Figure 3 and Figure 11 The locking sleeve 23 is connected to the second connector 22 via a drive structure 24. The drive structure 24 is used to drive the locking sleeve 23 to rotate in a first direction when the first tube 31 moves relative to the second tube 34 in a direction parallel to the axial center line. The locking sleeve 23 is provided with a first locking part 25, and the second tube 34 is provided with a second locking part 26.

[0097] It is understood that the first direction is a certain circumferential direction of the first tube 31. The specific direction of the first direction is not limited in the embodiments of this application. For example, in the direction parallel to the first connector 21 and pointing to the second connector 22, the first direction can be a counterclockwise direction or a clockwise direction.

[0098] During the locking process, the first tube 31 passes through the second tube 34, and the driving structure 24 drives the locking sleeve 23 to rotate to the locked position, thereby locking the first locking part 25 and the second locking part 26. Since the first locking part 25 is disposed on the locking sleeve 23, and the locking sleeve 23 is connected to the first tube 31, when the first locking part 25 and the second locking part 26 are locked, the positions of the first tube 31 and the second tube 34 are fixed, thereby preventing the first tube 31 from moving relative to the second tube 34 along the axial centerline. Correspondingly, the flow channels inside the first tube 31 and the second tube 34 are maintained, and the first tube 31 and the second tube 34 remain continuously connected.

[0099] During the unlocking process, the first tube 31 moves into the second tube 34, and the driving structure 24 drives the locking sleeve 23 to rotate to the unlocked position, so that the first locking part 25 and the second locking part 26 are unlocked. The first tube 31 moves relative to the second tube 34 along the axial centerline until the first connector 21 and the second connector 22 separate. Correspondingly, the flow channels inside the first tube 31 and the second tube 34 disappear, and the first tube 31 and the second tube 34 are resealed.

[0100] The fluid connector 20 provided in this embodiment includes a locking sleeve 23, which is connected to the second tube body 34 via a driving structure 24. The driving structure 24 can drive the locking sleeve 23 to rotate. Since the locking sleeve 23 is provided with a first locking part 25 and the second tube body 34 is provided with a second locking part 26, the driving structure 24 can change the relative position of the first locking part 25 and the second locking part 26 by driving the locking sleeve 23 to rotate, so that the first locking part 25 and the second locking part 26 can be locked or unlocked, thereby controlling the conduction or separation of the first connector 21 and the second connector 22, reducing the difficulty of disassembling and assembling the first connector 21 and the second connector 22.

[0101] Continue to refer to Figure 3 , Figure 5 and Figure 7 In the above embodiment, the drive structure 24 includes a first drive structure 41 and a second drive structure 42. The first drive structure 41 is disposed on the locking sleeve 23, and the second drive structure 42 is disposed on the second tube body 34.

[0102] The first driving structure 41 includes a driving block 63, the end of which facing the second driving structure 42 has a first inclined surface 631. The second driving structure 42 includes a driving flange 64 disposed on the outer periphery of the second tube body 34, and a plurality of driving grooves 43 are provided on the driving flange 64, the driving grooves 43 being arranged around the axial center line of the second tube body 34. The driving grooves 43 include intersecting first groove walls 431 and second groove walls 432, the first groove wall 431 being used to contact the first inclined surface 631 to drive the locking sleeve 23 to rotate.

[0103] The driving flange 64 is disposed on the outer periphery of the second tube body 34, and the position of the driving flange 64 is fixed. Due to the rotatable connection between the locking sleeve 23 and the first tube body 31, the first driving structure 41 can also rotate relative to the first tube body 31, that is, the driving block 63 can rotate relative to the first tube body 31.

[0104] It is understood that the specific positions of the drive block 63 and the drive flange 64 are not limited in the embodiments of this application. The positions of the drive block 63 and the drive flange 64 can be adjusted according to the actual structure. However, the distance between the drive block 63 and the drive flange 64 should be ensured so that the first connector 21 and the second connector 22 can be connected when the drive block 63 and the bottom of the drive groove 43 are in contact.

[0105] The end of the drive block 63 facing the second drive structure 42 has a first inclined surface 631. The drive groove 43 includes an intersecting first groove wall 431 and a second groove wall 432. When the first inclined surface 631 contacts the first groove wall 431, the first groove wall 431 will generate an oblique force on the first inclined surface 631, causing the first inclined surface 631 to move along the first groove wall 431 to the bottom of the drive groove 43, thereby realizing the rotation of the locking sleeve 23.

[0106] The shape of the first inclined surface 631 is not limited in this embodiment. For example, the first inclined surface 631 can be a plane, a curved surface, a wavy plane, etc. Correspondingly, the shapes of the first groove wall 431 and the second groove wall 432 are also not limited.

[0107] In the above embodiment, the drive block 63 includes a plurality of drive blocks 63, which are spaced apart around the axial center line of the first tube body 31.

[0108] Multiple drive blocks 63 are spaced apart around the axial center line of the first tube body 31, which can ensure that there is always a drive block 63 and a drive groove 43 matching during the rotation of the locking sleeve 23, so that the locking sleeve 23 can continue to rotate and realize the locking or unlocking of the first connector 21 and the second connector 22.

[0109] Please refer to Figure 7 and Figure 11In the above embodiment, the second locking part 26 includes a locking protrusion 45 disposed on the outer wall of the second tube body 34, and a channel 46 for the locking protrusion 45 to pass through is provided between adjacent driving blocks 63. The first locking part 25 includes a locking groove 44 disposed at one end of the driving block 63 away from the first inclined surface 631. The locking groove 44 includes a guide wall 441 and a locking wall 442. The locking wall 442 is disposed parallel to the axial center line of the first tube body 31, and the guide wall 441 is disposed inclined relative to the locking wall 442.

[0110] During the locking process, the first tube 31 and the second tube 34 approach each other, and the first groove wall 431 contacts the first inclined surface 631 to drive the locking sleeve 23 to rotate. The locking protrusion 45 rotates into the locking groove 44 and contacts the guide wall 441 to drive the locking sleeve 23 to rotate, so that the first inclined surface 631 contacts the first groove wall 431 of the next driving groove 43. In the locked position, the locking wall 442 contacts the locking protrusion 45.

[0111] Understandably, during the locking process, the first tube 31 and the second tube 34 approach each other, and there may be a positional deviation between the locking protrusion 45 and the channel 46. At this time, the locking protrusion 45 contacts the first inclined surface 631 and generates an oblique force, causing the locking protrusion 45 to move relative to the first inclined surface 631 into the channel 46. The first inclined surface 631 can guide the locking protrusion 45 into the channel 46, ensuring that the first connector 21 and the second connector 22 can be locked.

[0112] During the unlocking process, the first tube 31 and the second tube 34 approach each other, and the first inclined surface 631 contacts the first groove wall 431 of the next drive groove 43 to drive the locking sleeve 23 to rotate, and the locking protrusion 45 rotates into the groove 46. In the unlocked position, the first inclined surface 631 contacts the bottom of the drive groove 43.

[0113] There is a channel 46 between adjacent drive blocks 63 for the locking protrusion 45 to pass through. The second locking part 26 includes a locking protrusion 45 provided on the outer wall of the second tube body 34. The first locking part 25 includes a locking groove 44 provided at one end of the drive block 63 away from the first inclined surface 631. The locking protrusion 45 can cooperate with the locking groove 44 to lock the first connector 21 and the second connector 22. The channel 46 can guide the locking protrusion 45 to move to the vicinity of the locking groove 44.

[0114] The locking groove 44 includes a guide wall 441 and a locking wall 442. The locking wall 442 is parallel to the axial centerline of the first tube 31, and the guide wall 441 is inclined relative to the locking wall 442. The locking wall 442 can prevent the locking protrusion 45 from moving, so that the locking protrusion 45 is finally fixed at the bottom of the locking groove 44. The guide wall 441 is inclined relative to the locking wall 442, which ensures that when there is a positional deviation between the locking protrusion 45 and the bottom of the locking groove 44, the locking protrusion 45 contacts the guide wall 441, causing the locking sleeve 23 to rotate. The locking protrusion 45 moves along the guide wall 441 relative to the locking sleeve 23 to the bottom of the locking groove 44, ensuring that the first connector 21 and the second connector 22 can be locked.

[0115] In the above embodiment, the first locking part 25 includes a plurality of parts, and the first locking part 25 corresponds one-to-one with the driving block 63. The second locking part 26 includes a plurality of parts, and the plurality of second locking parts 26 are arranged at intervals around the axial center line of the second tube body 34.

[0116] The first locking part 25 includes multiple parts, and each first locking part 25 corresponds to a drive block 63. Multiple second locking parts 26 are arranged at intervals around the axial center line of the second tube body 34, which can ensure that the first locking part 25 and the second locking part 26 are always matched during the rotation of the locking sleeve 23, thus ensuring the locking of the first connector 21 and the second connector 22.

[0117] Continue to refer to Figure 7 and Figure 11 In the above embodiment, the drive block 63 further includes a guide surface 47, which is inclined relative to the locking wall 442. The guide surface 47 is located on the side of the locking wall 442 away from the guide wall 441, and the guide surface 47 is connected to the locking wall 442 and the channel 46 respectively.

[0118] Understandably, during the unlocking process, the locking protrusion 45 moves away from the locking groove 44 along the axial centerline. The locking protrusion 45 may have a positional deviation from the channel 46, moving between the locking wall 442 and the channel 46. The guide surface 47 is inclined relative to the locking wall 442 and is connected to both the locking wall 442 and the channel 46. The guide surface 47 and the locking protrusion 45 can generate mutual oblique forces, causing the locking protrusion 45 to move relative to the guide surface 47 towards the channel 46, ultimately guiding the locking protrusion 45 into the channel 46, thus achieving the separation of the first connector 21 and the second connector 22.

[0119] In embodiments where the drive block 63 includes multiple components and the locking groove 44 includes multiple components, the guide surface 47 also includes multiple components, which can ensure that the locking protrusion 45 can smoothly enter the groove 46 during each unlocking process, thereby realizing the separation of the first connector 21 and the second connector 22.

[0120] Please refer to Figure 12 , Figure 12 This is a diagram illustrating the process of externally locking the first connector 21 and the second connector 22.

[0121] During the locking process, the first connector 21 moves toward the second connector 22, the drive block 63 gradually approaches the drive groove 43, and at the same time the locking protrusion 45 moves toward the groove 46. The locking protrusion 45 directly enters the groove 46 or enters the groove 46 under the guidance of the first inclined surface 631.

[0122] The first inclined surface 631 gradually contacts the first groove wall 431, generating mutual oblique forces. Since the position of the first groove wall 431 is fixed, the first inclined surface 631 moves along the first groove wall 431 towards the bottom of the drive groove 43, and the locking sleeve 23 rotates. At the same time, the locking protrusion 45 passes through the channel 46 and rotates from the position corresponding to the channel 46 to the position corresponding to the drive groove 43.

[0123] When the first inclined surface 631 contacts the bottom of the drive groove 43, the locking protrusion 45 is located on the side of the locking groove 44 opposite to the first inclined surface 631. The locking protrusion 45 may be opposite to the bottom of the locking groove 44 or opposite to the guide wall 441. After the first inclined surface 631 contacts the bottom of the drive groove 43, the first connector 21 and the second connector 22 no longer move.

[0124] Under the action of the internal first elastic element 37 and second elastic element 38, the first tube 31 moves away from the second tube 34, and the locking protrusion 45 directly contacts the bottom of the locking groove 44. Alternatively, guided by the guide wall 441, the locking protrusion 45 moves relative to the first tube 31 along the guide wall 441 toward the bottom of the locking groove 44 until the locking protrusion 45 contacts the bottom of the locking groove 44. The first connector 21 and the second connector 22 complete the locking. At this time, the first inclined surface 631 corresponds to the first groove wall 431 of the next driving groove 43.

[0125] Please refer to Figure 13 , Figure 13 This is a diagram illustrating the process of externally unlocking the first connector 21 and the second connector 22.

[0126] During the unlocking process, the first connector 21 moves towards the second connector 22, the first inclined surface 631 moves towards the first groove wall 431, and the locking protrusion 45 gradually moves away from the locking groove 44. When the first inclined surface 631 contacts the first groove wall 431, a mutual oblique force is generated. Since the position of the first groove wall 431 is fixed, the first inclined surface 631 moves along the first groove wall 431 towards the bottom of the drive groove 43, and the locking sleeve 23 rotates. The locking protrusion 45 passes over the locking wall 442 and corresponds to the groove 46 or the guide surface 47.

[0127] When the first inclined surface 631 contacts the bottom of the drive groove 43, the locking protrusion 45 is located on the side of the channel 46 opposite to the first inclined surface 631, or on the side of the guide surface 47 opposite to the first inclined surface 631. After the first inclined surface 631 contacts the bottom of the drive groove 43, the first connector 21 and the second connector 22 no longer move.

[0128] Under the action of the internal first elastic element 37 and second elastic element 38, the first tube 31 moves away from the second tube 34, and the locking protrusion 45 passes directly through the channel 46, or, guided by the guide surface 47, the locking protrusion 45 moves relative to the first tube 31 along the guide surface 47 towards the channel 46, until the locking protrusion 45 passes through the channel 46. The first connector 21 and the second connector 22 are then unlocked.

[0129] Continue to refer to Figure 3 , Figure 5 and Figure 7 In the above embodiment, the end of the drive block 63 facing the second drive structure 42 has a second inclined surface 632, which intersects with the first inclined surface 631. The second inclined surface 632 is used to contact the second groove wall 432 to drive the locking sleeve 23 to rotate.

[0130] The end of the drive block 63 facing the second drive structure 42 has a second inclined surface 632. The second inclined surface 632 can contact the second groove wall 432. When the second inclined surface 632 and the second groove wall 432 are in contact, the second groove wall 432 will generate an oblique force on the second inclined surface 632, causing the second inclined surface 632 to move along the second groove wall 432 toward the bottom of the drive groove 43, causing the locking sleeve 23 to rotate.

[0131] The locking and unlocking of the first connector 21 and the second connector 22 can also be achieved through the contact of the second inclined surface 632 and the second groove wall 432, thereby reducing the positional accuracy requirements of the first inclined surface 631 and the first groove wall 431 and reducing the manufacturing difficulty of the drive block 63 and the drive flange 64.

[0132] In addition, during the locking process, the first tube 31 and the second tube 34 approach each other, and the locking protrusion 45 may have a positional deviation from the channel 46. The first inclined surface 631 and the second inclined surface 632 can contact the locking protrusion 45, guide the locking protrusion 45 into the channel 46, and realize the locking of the first connector 21 and the second connector 22.

[0133] Please refer to Figure 14 , Figure 14 This is a diagram illustrating the process of externally locking the first connector 21 and the second connector 22.

[0134] The first connector 21 moves toward the second connector 22, the first tube 31 moves into the second tube 34, the drive block 63 gradually approaches the drive groove 43, and at the same time the locking protrusion 45 moves toward the groove 46. The locking protrusion 45 directly enters the groove 46 or enters the groove 46 under the guidance of the second inclined surface 632.

[0135] The second inclined surface 632 gradually contacts the second groove wall 432, generating mutual oblique forces. Since the position of the second groove wall 432 is fixed, the second inclined surface 632 moves along the second groove wall 432 towards the bottom of the drive groove 43, causing the locking sleeve 23 to rotate. Simultaneously, the locking protrusion 45 passes through the channel 46 and rotates from its position corresponding to the channel 46, over the guide surface 47, to its position corresponding to the drive groove 43.

[0136] When the first inclined surface 631 contacts the bottom of the drive groove 43, the locking protrusion 45 is located on the side of the locking groove 44 opposite to the second inclined surface 632. The locking protrusion 45 is opposite to the bottom of the locking groove 44. After the second inclined surface 632 contacts the bottom of the drive groove 43, the first connector 21 and the second connector 22 no longer move.

[0137] Under the action of the first elastic element 37 and the second elastic element 38, the first tube 31 moves away from the second tube 34, and the locking protrusion 45 directly contacts the bottom of the locking groove 44. The first connector 21 and the second connector 22 are locked. At this time, the second inclined surface 632 corresponds to the second groove wall 432 of the next driving groove 43.

[0138] Please refer to Figure 15 , Figure 15 This is a diagram illustrating the process of externally unlocking the first connector 21 and the second connector 22.

[0139] The first connector 21 moves closer to the second connector 22, and the first tube 31 moves into the second tube 34. At this time, the second inclined surface 632 contacts the second groove wall 432 and generates mutual oblique forces. Since the position of the second groove wall 432 is fixed, the second inclined surface 632 moves along the second groove wall 432 towards the bottom of the drive groove 43, and the locking sleeve 23 rotates. The locking protrusion 45 passes over the guide wall 441 and corresponds to the channel 46 or the guide surface 47.

[0140] When the second inclined surface 632 contacts the bottom of the drive groove 43, the locking protrusion 45 is located on the side of the channel 46 opposite to the second inclined surface 632, or on the side of the guide surface 47 opposite to the second inclined surface 632. After the second inclined surface 632 contacts the bottom of the drive groove 43, the first connector 21 and the second connector 22 no longer move.

[0141] Under the action of the internal first elastic element 37 and second elastic element 38, the first tube 31 moves away from the second tube 34, and the locking protrusion 45 passes directly through the channel 46, or, guided by the guide surface 47, the locking protrusion 45 moves relative to the first tube 31 along the guide surface 47 towards the channel 46, until the locking protrusion 45 passes through the channel 46. The first connector 21 and the second connector 22 are then unlocked.

[0142] It is understandable that the cooperation between the first inclined surface 631 and the first groove wall 431, as well as the cooperation between the second inclined surface 632 and the second groove wall 432, can achieve the locking and unlocking of the first connector 21 and the second connector 22. The angles and lengths of the first inclined surface 631, the second inclined surface 632, the first groove wall 431, and the second groove wall 432 can be adjusted according to actual needs.

[0143] Continue to refer to Figure 7 In the above embodiment, the second connector 22 includes a guide channel 50, which is disposed on the second tube 34 near the first connector 21. Figure 3 (as shown). The guide channel 50 includes a first end face 51 and a second end face 52. The second end face 52 is connected to the second tube body 34. The area of ​​the first end face 51 is larger than the area of ​​the second end face 52.

[0144] Since the area of ​​the first end face 51 is larger than the area of ​​the second end face 52, the guide channel 50 is a hollow frustum structure, which is horn-shaped.

[0145] It is understandable that in the first tube 31 ( Figure 3 As shown, when moving towards the direction of the second pipe body 34, the axial center line of the first pipe body 31 and the axial center line of the second pipe body 34 do not coincide, which may cause the first pipe body 31 to be unable to pass through the second pipe body 34, and the connection between the first connector 21 and the second connector 22 will fail.

[0146] The first end face 51 is closer to the first connector 21 than the second end face 52, and the area of ​​the first end face 51 is larger than the area of ​​the second end face 52. When the axial center line of the first tube 31 and the axial center line of the second tube 34 do not coincide, the first tube 31 can move along the inner wall of the guide channel 50 so that the axial center line of the first tube 31 coincides with the axial center line of the second tube 34, thereby allowing the first tube 31 to pass through the second tube 34 and realize the connection between the first connector 21 and the second connector 22.

[0147] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
