DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0049] The core of the present application is to provide a fluid connector and a connecting end of the fluid connector, which can improve the use efficiency of the fluid connector.

[0050] The fluid connector according to the first embodiment of the present application mainly includes an operating part 1 and at least two connecting parts 2, specifically two connecting parts 2, which are a first connecting part 21 and a second connecting part 22.

[0051] As shown in Figs. 1 and 4, the connecting part 2 mainly includes a valve seat 3 and a valve 4, and the valve 4 is movably arranged in the valve seat 3 to open and close the communication passage 31 in the valve seat 3. It can be understood that the valve seat 3 is provided with a communication passage 31 for fluid communication.

[0052] The communication passages 31 of the two connecting parts 21 can be straight passages, and at least one of them can also be a curved passage. One end of the communication passage 31 is used for abutting with the communication passage 31 in the other connecting part 2, and the other end can be used for connecting with a pipeline or other passage structure.

[0053] In the valve 4 controls the way of the communication passage 31 open and close, specifically, as shown in Figure 1, in at least one connecting part 2, on the valve 4, it has a communication hole 41, that is, the valve 4 is provided with a communication hole 41 for fluid communication, when the valve 4 moves relative to the valve seat 3, by changing the communication hole 41 and the communication passage 31 communication and stagger, to control the opening and closing of the communication passage 31. Specifically, when the communication hole 41 and the corresponding communication passage 31 is completely staggered, then the corresponding communication passage 31 can be closed or closed, so that the fluid can not pass through the communication passage 31; otherwise, the communication hole 41 is communicated with the communication passage 31, opening (partial opening or complete opening) the communication passage 31, generally, the communication hole 41 and the communication passage 31 are aligned, such as shaft arrangement, at this time, the communication passage 31 is better opened. It can be understood that the shape and size of the communication hole 41 and the communication passage 31 should be substantially the same, even completely the same, to achieve better connection effect. Of course, the valve 4 can also not form the above-mentioned communication hole 41, at this time, the valve 4 is used as a solid structure: when it moves to the communication passage 31, it is blocked at one end of the communication passage 31, so as to realize the closing or disconnection of the communication passage 31; when it avoids the communication passage 31, it opens or opens the corresponding end of the communication passage 31, so as to open the communication passage 31.

[0054] The operation part 1 and the valve 4 on each connecting part 2 are in transmission connection, for example, the operation part 1 can be in transmission connection with different valves 4, without the need for the valves 4 of different connecting parts 2 to transmit the movement or force of the operation part 1; or, when the operation part 1 moves, there is a valve 4 as an intermediate transmission part, that is, the operation part 1 can be in transmission connection with the valve 4 of one connecting part 2 and the valve 4 of another connecting part 22, at this time, the movement or force of the operation part 1 can be transmitted to the valve 4 of the former connecting part 2 and needs to be transmitted to the valve 4 of the latter connecting part 22 through the valve 4 of the former connecting part 2.

[0055] In the state that two connecting parts 2 abut, when the operation part 1 moves, the operation part 1 can drive the valve 4 on the first connecting part 21 to move relative to the valve seat 3 on the first connecting part 21, and drive the valve 4 on the second connecting part 22 to move relative to the valve seat 3 on the second connecting part 22, so as to open and close the corresponding communication passage 31. In the state that at least two connecting parts 2 abut, for example, in the state that two connecting parts 2 abut or in the state that one pair of two connecting parts 2 abut, when the operation part 1 moves, the operation part 1 can drive the valve 4 on at least two connecting parts 2 to move relative to the corresponding valve seat 3, so as to open and / or close the corresponding communication passage 31.

[0056] Specifically, under the drive of the operation part 1, when one of the communication channels 31 is in the opening movement, the other communication channels 31 are also in the opening movement or are about to be in the opening movement; correspondingly, when one of the communication channels 31 is in the closing movement, the other communication channels 31 are also in the closing movement or are about to be in the closing movement.

[0057] It should be noted that the opening and closing here refer to the ability to open and close the communication channel 31 and switch between the two, rather than referring to the realization of both opening and closing at the same time. Referring to FIGS. 7 and 8, FIG. 7 shows that under the drive of the operation part 1, the communication channels 31 of the two connection parts 2 are both in the closed state, at this time, the fluid in the communication channel 31 of one connection part 2 cannot flow into the communication channel 31 of the other connection part 2 under the blockage of the valves 4 of the two connection parts 2, and FIG. 8 shows that under the drive of the operation part 1, the communication channels 31 of the two connection parts 2 are both opened, so that the corresponding communication channels 31 of the two connection parts 2 are in the state of communication, at this time, the fluid in the communication channel 31 of one connection part 2 can flow into the corresponding communication channel 31 of the other connection part 2.

[0058] It should be noted that, unless otherwise specified, the components with a corresponding relationship are located in the same connection part 2.

[0059] Among them, the transmission between the operation part 1 and the valve 4 can be selected as link connection, magnetic force transmission, gear transmission, etc. according to needs; the transmission path can be selected as: the transmission between each valve 4 in turn, and the transmission between the operation part 1 and one of the valves 4; the transmission between the operation part 1 and each valve 4 respectively.

[0060] Among them, for the state that at least two connection parts 2 abut, the abutting end parts of the different connection parts 2 are usually set to abut, wherein each connection part 2 can have one or at least two abutting end parts, and the abutting end part is usually related to the position of the inflow or outflow of the fluid in the connection part 2. For example, in the embodiment, the valve 4 in the connection part 2 is arranged at one end of the valve seat 3, and the abutting end parts of the two connection parts 2 abut, which means that the one ends of the two connection parts 2 where the valves 4 are arranged abut, and more specifically, the valves 4 of the two connection parts 2 can abut. In other embodiments, the valve 4 in the connection part 2 can be arranged in the middle of the valve seat 3, and then the abutting end parts of the two connection parts 2 can be arranged to abut, which means that the set positions of the valve seats 3 of the two connection parts 2 abut. Usually, when the fluid passes through the fluid connector, the fluid flows out of the abutting end part of the previous connection part 2, enters the abutting end part of the next connection part 2, and then continues to flow in the next connection part 2.

[0061] Of course, in other embodiments, the movement of the operation part 1 can only make the communication channels 31 of the two connection parts 2 open but not close, or only make the communication channels 31 of the two connection parts 2 close but not open.

[0062] In the embodiment, the operation part 1 is additionally arranged, and by adjusting the operation part 1, the valve 4 in different connection parts 2 can be driven to move, and the opening and / or closing of different communication channels 31 can be adjusted, so that the use efficiency of the fluid connector can be improved.

[0063] In order to realize the assembly and disassembly between the two connection parts 2, as shown in FIGS. 7 and 8, the operation part 1 is further connected with the locking structure 5. When the operation part 1 moves in the state that the two connection parts 2 abut against each other, the operation part 1 can drive the locking structure 5 to move, so that the locking and disconnection between the two connection parts 2 are realized. Here, the operation part 1 can drive the locking structure 5 to realize the locking and disconnection, and the switching between the locking and disconnection can be realized, instead of realizing the locking and disconnection at the same time. Of course, in other embodiments, the operation part 1 can only drive the locking structure 5 to realize the locking of the two connection parts 2, but cannot drive the locking structure 5 to disconnect the two connection parts 2, or the operation part 1 can only drive the locking structure 5 to realize the disconnection of the two connection parts 2, but cannot drive the locking structure 5 to lock the two connection parts 2.

[0064] It should be noted that the locking of the two connection parts 2 can refer to the determination of the relative positions of the valve seats 3 of the two connection parts 2, so as to ensure the smooth flow of the fluid between the two connection parts 2, and the position of the valve 4 relative to the corresponding valve seat 3 can be changed, for example, the position of the valve 4 relative to the corresponding valve seat 3 is changed under the driving of the operation part 1, so that the valve 4 opens and closes the corresponding communication channel 31. The closing of the two connection parts 2 can refer to the separability of the two connection parts 2, as shown in FIG. 6, the two connection parts 2 can be in a split state and move independently. In addition, the locking can also be explained as the reverse limiting of the different connection parts 2 in the abutting direction, so that when the different connection parts 2 abut against each other in the abutting direction, the reverse movement of the different connection parts 2 in the abutting direction can be avoided by the locking. The disconnection, that is, the unlocking, the different connection parts 2 are no longer reversely limited in the abutting direction, and the different connection parts 2 can reversely move in the abutting direction to be separated.

[0065] In the embodiment, the operation part 1 can not only control the opening and closing of the valve 4 relative to the corresponding communication channel 31, but also has the function of controlling the assembly and disassembly of the two connection parts 2, so that the multifunctionality of the operation part 1 is realized. In addition, in the assembly of the different connection parts 2 and the opening and closing adjustment of the communication channel 31, only the operation part 1 needs to be adjusted, so that the operation position of the user is unified.

[0066] Of course, in other embodiments, the movement of the operation part 1 can be used to drive the valve 4 to open or close the corresponding communication passage 31, and / or, can be used to drive the locking structure 5 to lock and / or unlock. The above two modes can exist independently in an embodiment. In some specific embodiments, when the valve 4 needs to be driven to open or close the corresponding communication passage 31 by rotation, or when the locking structure 5 needs to be driven to lock or unlock by rotation, the above technical effects can be achieved by providing a separate operation part 1, that is, avoiding the rotation of the valve seats 3 of the two connecting parts 2 relative to each other, thereby achieving the above structure.

[0067] Alternatively, in other embodiments, the locking structure 5 can also have no connection relationship with the operation part 1. For example, the locking structure 5 can be a magnetic or buckle structure directly fixed on the valve seats 3 of the two connecting parts 2, and the two connecting parts 2 are directly detachably connected through the locking structure 5 to achieve the locking and / or disconnection of the two connecting parts 2. Alternatively, the locking structure 5 is a separate locking rod which is separately provided from the operation part 1 and the connecting part 2, and by providing locking holes on the outer surfaces of the valve seats 3 of the two connecting parts 2, the two ends of the locking rod can be simultaneously detachably inserted into the corresponding locking holes of the two connecting parts 2, thereby achieving the locking and / or disconnection of the two connecting parts 2. Alternatively, the valve seats 3 of the two connecting parts 2 or the valves 4 of the two connecting parts 2 can be threadedly locked.

[0068] In order to improve the operation efficiency of the operation part 1, in one preset operation action of the operation part 1, the valve 4 is driven to open the corresponding communication passage 31, and the locking structure 5 is locked; and in the reverse operation process of the preset operation action or other operation actions, the valve 4 is driven to close the corresponding communication passage 31, and the locking structure 5 is unlocked. Among them, the valve 4 driven to open the communication passage 31 and the locking structure 5 locked do not require to be performed synchronously, can be staggered, can be performed synchronously, can be partially synchronous and partially staggered, and the sequence can be adjusted passively or actively under different conditions. Among them, the sequence of the valve 4 driven to close the corresponding communication passage 31 and the locking structure 5 unlocked can also be set as above and is not limited by the above.

[0069] It should be noted that the preset operation stroke is intended to facilitate operation, which can be single sliding, rotation, spiral movement, etc., and the specific implementation is subject to the above effects. The above other operation actions are continuation actions of the above preset operation actions.

[0070] Specifically, as shown in FIG. 7 and FIG. 8, in the state that the two connecting parts 2 abut against each other, the operation part 1 is active, which can drive the locking structure 5 to lock the two connecting parts 2, and after locking, drive the valves 4 on the two connecting parts 2 to move relative to the corresponding valve seats 3 to open the communication passages 31 of the two connecting parts 2. That is, the operation part 1 drives the locking of the two connecting parts 2 and the opening of the corresponding communication passages 31 is sequentially performed.

[0071] For the sequential mode, the state that the two connecting parts 2 abut against each other as shown in FIG. 7 is the initial state, at this time, the two connecting parts 2 are just abutted together, and the two connecting parts 2 are not in a connected relationship, and can still be freely separated, and the valves 4 close the corresponding communication passages 31. By driving the operation part 1 to move by an external force, the operation part 1 drives the locking structure 5 to move, so that the two connecting parts 2 are connected together, the locking structure 5 reaches the set locking position, and the locking process is completed, at this time, each communication passage 31 can be in a closed state. Then, continue to drive the operation part 1 to move (specifically, it can move along the original direction, for example, always rotate clockwise, or always translate in the set direction, or it can change direction to continue to move in other embodiments), the two valves 4 open the corresponding communication passages 31, until the valve 4 of the first connecting part 21 and the valve 4 of the second connecting part 22 complete the opening action, the communication passages 31 of the two connecting parts 2 are in the communication state of FIG. 8, wherein the valve 4 completing the opening action refers to the valve 4 moving to a position where the valve 4 blocks the corresponding communication passage 31 to the least extent, at this time, the communication passage 31 is completely open.

[0072] In another embodiment, in the state that the two connecting parts 2 abut against each other, when the operation part 1 is active, it can drive the locking structure 5 to lock the two connecting parts 2, and drive the valves 4 on the two connecting parts 2 to move relative to the corresponding valve seats 3 during the locking process to open the communication passages 31 of the two connecting parts 2. That is, in this embodiment, the operation part 1 drives the locking of the two connecting parts 2 and the opening of the corresponding communication passages 31 is cross-performed.

[0073] For the cross-acting mode, in the initial state where the two connecting parts 2 abut against each other, the valve 4 closes the corresponding communication passage 31, and in the locking process (for example, at the time when the locking structure 5 starts to lock, or before the locking structure 5 has moved to a position set for the locking position), the valve 4 of at least one connecting part 2 also opens the corresponding communication passage 31 along with the operation part 1. Among them, the valves 4 of the two connecting parts 2 can start to open simultaneously, or sequentially, and the movement speed can be the same or different. When the locking process is completed, the valves 4 of the two connecting parts 2 can also complete the opening action simultaneously, or at least one valve 4 does not complete the opening action, and continues to control the operation of the operation part 1 until the valves 4 of the two connecting parts 2 are completed. The opening action is completed, so that the communication passages 31 of the first connecting part 21 and the second connecting part 22 are communicated.

[0074] From the use effect, the sequential mode is better in the anti-leakage effect, especially in the case where the connecting part 2 has fluid, because the valve 4 always closes the corresponding communication passage 31 before the locking of the two connecting parts 2 is completed. If the external device of the connecting part 2 has not been started, and each connecting part 2 has not entered the fluid, the cross-acting mode is more efficient.

[0075] Of course, in other embodiments, if the operation of the operation part 1 to drive the valve 4 to open the corresponding communication passage 31 is prior to the operation of the operation part 1 to drive the locking of the two connecting parts 2, it may be necessary to assist the external sealing structure between the two connecting parts 2 to avoid the leakage of the fluid of the connecting part 2.

[0076] In addition, during the process of controlling the operation part to disconnect the two connecting parts 2 and drive the two valves 4 to close the corresponding communication passages 31, the locking structure 5 can be driven to perform the disconnection action after driving the two valves 4 of the two connecting parts 2 to close the corresponding communication passages 31 synchronously or asynchronously; or the locking structure 5 can be driven to perform the disconnection action only after driving one of the valves 4 to close the corresponding communication passage 31; or the locking structure 5 can be driven to perform the disconnection action without driving the two valves 4 of the two connecting parts 2 to close the corresponding communication passages 31.

[0077] In order to facilitate processing and ensure the reliability of the connection, the locking structure 5 is a clamping structure, which can include a clamping hook 51 provided on the valve 4 or valve seat 3 of the first connecting part 21, and correspondingly, a clamping groove 52 matched with the clamping hook 51 for clamping cooperation is provided on the valve 4 or valve seat 3 of the second connecting part 22.

[0078] In the state that the specific end portions (i.e. the abutting end portions) of the first connecting portion 21 and the second connecting portion 22 abut against each other, the two connecting portions 2 are arranged in sequence along the preset direction X, and specifically, the two connecting portions 2 can perform the clamping action after abutting against each other; in other embodiments, the clamping structure can perform the clamping action during the process that the two connecting portions 2 approach along the preset direction X, and the clamping is completed when the two connecting portions 2 abut against each other.

[0079] In order to further facilitate the assembly, as shown in FIGS. 1, 2 and 6, the operation portion 1 is arranged on the first connecting portion 21, and specifically, the operation portion 1 can be arranged on the valve seat 3 of the first connecting portion 21, and the first connecting portion 21 and the operation portion 1 constitute the first connecting end 23; the second connecting portion 22 constitutes the second connecting end 24. During the assembly process, the operation portion 1 and the first connecting portion 21 do not need to be separately assembled, and the loss of the operation portion 1 can be avoided. Of course, in other embodiments, the operation portion 1 is a separate component independent of the two connecting portions 2.

[0080] In order to facilitate the control of the operation portion 1, as shown in FIGS. 7 and 8, in the state that the two connecting portions 2 abut against each other, at least part of the structure of the operation portion 1 is exposed to one of the connecting portions 2, and this exposed part can serve as a driving portion, so that the user or an external device can apply an external force to the operation portion 1 to make the operation portion 1 move.

[0081] Specifically, as shown in FIG. 1, the operation portion 1 includes a sleeve 11 sleeved outside the valve seat 3 of the first connecting portion 21, and the valve seat 3 of the first connecting portion 21 is provided with a control hole 2, and the operation portion 1 can be connected to the valve 4 in the first connecting portion 21 at the control hole 2 through a transmission structure such as a connecting rod 42, and the operation portion 1 drives the valve 4 of the two connecting portions 2 to move through rotation or translation. Of course, in other embodiments, the operation portion 1 can also have other structures, for example, the sleeve 11 described above is cancelled, and the connecting rod 42 connected between the sleeve 11 and the valve 4 is directly used as the operation portion.

[0082] In order to improve the adjustment efficiency, in the state that the two connecting portions 2 abut against each other, the two connecting portions 2 are arranged in sequence along the preset direction X, and the operation portion 1 is rotationally connected to the first connecting portion 21, and specifically, the operation portion 1 is rotationally sleeved outside the valve seat 3 of the first connecting portion 21, and the rotation axis of the operation portion 1 is parallel to the preset direction X. The operation portion 1 opens the communication passages 31 of the two connecting portions 2 and locks the two connecting portions 2 by rotating in one direction, i.e. always clockwise or always counterclockwise, so that only one-way operation of the operation portion 1 is needed, and the adjustment efficiency of the valve 4 and the locking structure 5 is further improved.

[0083] Wherein, when the operation part 1 rotates, the valve 4 in the first connecting part 21 can rotate synchronously with the operation part 1, and at a certain moment (initial moment or intermediate moment) in the rotating process of the valve 4, the valve in the second connecting part 22 can also rotate synchronously with the valve in the first connecting part 21, and the rotation axes of the two valves 4 can also be parallel to the preset direction X, and the synchronization of movement can also be facilitated by the position of the operation part 1 to determine the positions of the two valves 4 in the corresponding valve seats 3.

[0084] In addition, in other embodiments, the operation part 1 can also not have an exposed part, but be built-in in one of the connecting parts 2, for example, be built-in in the first connecting part 21, at which time, it is usually required that the operation part 1 has good waterproof performance, which can specifically include an electric control power structure (for example, a motor). Specifically, the operation part 1 in the first connecting part 21 is connected with the locking structure 5 and the valve 4 in the first connecting part 21 and the locking structure 5 respectively (for example, the motor is drivingly connected with the valve 4 and the locking structure 5 respectively), and the locking structure 5 can be connected on the valve seat 4 of the first connecting part 21. In the state that the two connecting parts 2 abut against each other, the operation part 1 in the first connecting part 21 and the valve 4 in the second connecting part 22 are drivingly connected through plug-in, clamping or other modes, the operation part 1 receives the instructions of an external device through a wireless communication mode such as Bluetooth, drives the locking structure 5 to clamp or tightly hold the valve seat 3 of the second connecting part 21 to achieve locking, and drives the valve 4 of the first connecting part 21 and the valve 4 of the second connecting part 22 to perform corresponding opening movement.

[0085] In order to realize the transmission of the operation part 1 to the two valves 4, as shown in FIGS. 1 and 4, the operation part 1 is connected to the valve 4 in the first connecting part 21, and the locking structure 5 is arranged between the two valves 4 of the two connecting parts 2, at which time, the locking structure 5 can be used as a transmission member between the valve 4 of the first connecting part 21 and the valve 4 of the second connecting part 22 in addition to having locking ability.

[0086] Wherein, for the process of opening the communication channel 31, in the state that the first connecting part 21 and the second connecting part 22 abut against each other, the operation part 1 is movable to drive the valve 4 in the first connecting part 21 to move, and the operation part 1 can in turn drive the valve 4 in the second connecting part 22 to move through the valve 4 in the first connecting part 21 and the locking structure 5 to open the communication channel 31 of the two connecting parts 2, and the locking action of the locking structure 5 can be performed before, during or after the opening action of each valve 4. For the process of closing the communication channel 31 of the two connecting parts 2, it can be performed in the locked state of the two connecting parts 2 or in the process of disconnecting the two connecting parts 2.

[0087] In addition, in the locking process, in the state that the two connecting portions 2 abut against each other, the operation portion 1 is movable to drive the valve 4 in the first connecting portion 21 to move, and in this process, the valve 4 in the second connecting portion 22 can be kept stationary relative to the corresponding valve seat 3, so as to lock the valve 4 in the first connecting portion 21 and the valve 4 in the second connecting portion 22 by the locking structure 5.

[0088] For the specific structural arrangement of the connecting portions 2 and the operation portion 1, as shown in FIGS. 1 to 3, in the first connecting portion 21, the valve 4 is rotationally connected to the valve seat 3, and the valve seat 3 is provided with a control hole 32, and the valve 4 is connected to the operation portion 1 outside the valve seat 3 through the control hole 32. Specifically, the control hole 32 is provided with a first transmission structure to connect the valve 4 and the operation portion 1.

[0089] The operation portion 1 comprises a sleeve 11 rotationally sleeved outside the valve seat 3, and the first transmission structure comprises a connecting rod 42 having two ends fixedly connected to the operation portion 1 and the valve 4, respectively. The sleeve 11 is driven to rotate by the sleeve 11 to drive the valve 4 to synchronously rotate. In addition, the sleeve 11 has the advantage of shielding the control hole 32. Optionally, when the operation portion 1 is at any position within its movable range, the operation portion 1 always covers the control hole 32, which can reduce the entry of external objects (including dust and other external pollutants) into the control hole 32, thereby reducing the direct contact or impact of external objects on the valve 4 or into the connecting portion 2 through the control hole 32, and further reducing the influence on the normal use of the fluid connector at the control hole 22. In addition, the sleeve 11 can protrude from one end of the valve seat 3 of the first connecting portion 21, and in the state that the two connecting portions 2 abut against each other, the sleeve 11 can shield the abutment position of the two connecting portions 2, thereby improving the shielding capability. In other embodiments, the operation portion 1 can be a baffle, for example, a rectangular baffle; or the operation portion 1 can be a knob which drives the valve 4 to rotate or move through a gear transmission structure.

[0090] In the second connecting portion 22, the valve 4 is also rotationally connected to the valve seat 3. When the specific end portions (i.e., the abutment end portions) of the two connecting portions 2 abut against each other, the arrangement direction of the two connecting portions 2 is a preset direction X, and the rotation axis of the valve 4 relative to the valve seat 3 in each connecting portion 2 can be parallel to the preset direction X. Alternatively, in the first connecting portion 21 or the second connecting portion 22, the valve 4 and the valve seat 3 can also be movably connected in the form of translation, for example, the valve 4 is specifically a baffle structure and is movably connected to the valve seat 3, and the opening and closing control is realized by shielding or opening one port of the communication passage 31.

[0091] For the specific structure of the locking structure 5, which is a clamping structure and connected between the two connecting portions 2 and the valve 4, as shown in FIG. 1 and FIG. 4, the clamping structure can specifically include a clamping hook 51 fixed on the valve 4 of the first connecting portion 21, and the other valve 4 of the second connecting portion 22 is provided with a clamping groove 52. Of course, in other embodiments, the clamping hook 51 can be provided on the valve 4 of the second connecting portion 22, and the clamping groove 52 can be provided on the valve 4 of the first connecting portion 21.

[0092] Wherein, as shown in FIG. 1, in the first connecting portion 21, the valve 4 is located on one side of the communication passage 31 in the preset direction X, and the other side is used for fixedly arranging the clamping hook 51 to connect the second connecting portion 22. As shown in FIG. 4, in the second connecting portion 22, the valve 4 is located on one side of the communication passage 31, and the clamping groove 52 is arranged on the valve 4.

[0093] Wherein, as shown in FIG. 9 to FIG. 11, the clamping groove 52 is an L-shaped groove, which includes a first groove body 521 extending along the preset direction X and a second groove body 522 having an included angle with the first groove body 521. The first groove body 521 and the second groove body 522 can be arranged vertically, and the second groove body 522 is located on one side of the first groove body 521 in the circumferential direction (corresponding to the circumferential direction of the rotation axis of the valve 4).

[0094] Wherein, as shown in FIG. 1, FIG. 9 to FIG. 11, the clamping hook 51 includes a rod portion 511 fixed on the valve 4 and a hook portion 512 fixed on the rod portion 511. The hook portion 512 is located on one side of the rod portion 511 in the circumferential direction (corresponding to the circumferential direction of the rotation axis of the valve 4).

[0095] When the clamping hook 51 and the clamping groove 52 are assembled and disassembled, the clamping hook 51 can first enter the first groove body 521 along the preset direction X, as shown in FIG. 9. The first groove body 521 can accommodate the entire clamping hook 51 until the two valves 4 abut. Then, as shown in FIG. 10, the operating portion 1 is moved to drive the valve 4 of the first connecting portion 21 to move, so that the hook portion 512 of the clamping hook 51 enters the second groove body 522.

[0096] Of course, in other embodiments, the clamping groove 52 can also include an accommodation through hole penetrating through the valve 4 of the second connecting portion 22 along the preset direction X, and the clamping hook 51 can pass through the accommodation through hole. The valve 4 of the second connecting portion 22 has a gap with the valve seat 3 for accommodating the hook portion 512 of the clamping hook 51. When locked, the hook portion 512 of the clamping hook 51 enters the gap and hooks the side of the valve 4 close to the communication passage 31.

[0097] In addition, the operation part 1 is active, and the valve 4 of the first connecting part 21 is moved, so that the hook-shaped part 512 of the clamping hook 51 enters or exits the second groove body 522, and the valve 4 of the second connecting part 22 needs to have relative motion with the clamping hook 51, which can be achieved by setting a starting limiting structure and an ending limiting structure between the valve 4 and the valve seat 3 in the second connecting part 22.

[0098] For example, a positioning groove 53 is arranged on one of the valve 4 and the valve seat 3, and a protrusion 54 is arranged on the other, the positioning groove 53 is buckled on the protrusion 54 along the preset direction X, so that when the force applied to the operation part 1 is less than the set value, the valve 4 and the valve seat 3 in the second connecting part 22 keep the relative position unchanged until the locking state in FIG. 10 is reached, and then the external force applied to the operation part 1 is increased to make the protrusion 54 and the positioning groove 53 staggered, as shown in FIG. 11, and the valve 4 of the first connecting part 21 is driven by the locking structure 5 to move the valve 4 of the second connecting part 22. In addition, one of the valve 4 and the valve seat 3 in the second connecting part 22 is provided with a soft sealing pad, such as a rubber pad, and the positioning groove 53 is arranged on the sealing pad, so that after the positioning groove 53 and the protrusion 54 are staggered, the protrusion 54 can press the sealing pad to move, and the structure will not be damaged due to the movement of the protrusion 54.

[0099] At this time, for the disassembly process, that is, the disconnection process of the locking structure 5, the valve 4 and the valve seat 3 in the second connecting part 22 can have sufficient friction, so that the operation part 1 moves reversely, at this time, the valve 4 of the second connecting part 22 and the clamping groove 52 remain stationary, and the clamping hook 51 can directly exit the second groove body 522 to achieve disconnection, that is, at this time, the operation part 1 cannot drive the valve 4 of the second connecting part 22 to close the communication channel 31 of the second connecting part 22, and the position of the valve 4 of the second connecting part 22 can be manually adjusted after the first connecting part 21 and the second connecting part 22 are separated.

[0100] Alternatively, the starting limit structure can be other settings, for example, in the second connecting part 22, one of the valve 4, valve seat 3 is provided with a sliding groove, the other is provided with a sliding block, to limit the valve 4 can be relative to the valve seat 3 in two directions of rotation of the two limit position, at this time, the operation part 1 drive the valve 4 of the first connecting part 21 movement, so that the hook 512 of the hook 51 into the second slot 522 in the process, the hook 51 can be in the second slot 522 before or intermediate position when the valve 4 of the second connecting part 22 movement, the sliding block relative to the sliding groove movement, until the sliding block and one end of the sliding groove, then the valve 4 of the second connecting part 22 no longer movement, the hook 51 can continue to enter the second slot 522, or, also can be the hook 51 completely into the second slot 522, then, the valve 4 of the second connecting part 22 movement, until the sliding block and one end of the sliding groove, at this time, the sliding block and the sliding groove constitute starting limit structure, and when the abutment, the valve 4 of the second connecting part 22 completely open the corresponding communication channel 31, and the valve 4 of the first connecting part 21 can be completely open the corresponding communication channel 31.

[0101] At this time, for the disassembly process, that is, the unlocking process of the locking structure 5, the operation part 1 drives the valve 4 reverse movement, the hook 51 and the card slot 52 can keep synchronous movement by means of friction, so that the valve 4 of the first connecting part 21 and the valve 4 of the second connecting part 22 are closed to the corresponding communication channel 31. In this process, the sliding block and the sliding groove also move relatively. When the sliding block and the other end of the sliding groove abut, the sliding block and the sliding groove constitute the end limit structure. The valve 4 of the second connecting part 22 closes the communication channel 31 of the second connecting part 22, and the valve 4 of the first connecting part 21 closes or partially opens the communication channel 31 of the first connecting part 21. At this time, the valve 4 of the second connecting part 22 cannot continue to move with the hook 51, and the operation part 1 can drive the hook 51 to continue to move in the second slot 522 until it can be removed from the first slot 521 in the preset direction X, completing the unlocking process. When the process is completed, the valve 4 of the first connecting part 21 can close the corresponding communication channel.

[0102] Of course, in other embodiments, the locking structure 5 can also be directly provided on the operation part 1. The operation part 1 is provided on the first connecting part 21. In the state that the two connecting parts 2 abut, the operation part 1 is locked relative to the first connecting part 21 in the preset direction X. This can be achieved by clamping the first connecting part 21 in the direction. The locking structure 5 can clamp the valve seat 3 of the second connecting part 22, for example, the locking structure 5 is an elastic clamping block, which is clamped on the groove on the outer surface of the valve seat 3 of the second connecting part 22 by elastic deformation perpendicular to the preset direction X, so as to lock the first connecting part 21 and the second connecting part 22.

[0103] In addition, in other embodiments, the locking structure 5 can also be arranged between the valve seat 3 of one of the two connecting parts 2 and the valve 4 of the other connecting part 2, or between the two abutted connecting parts 2, or between the two specific structures that are relatively rotated during the abutting process, to achieve the rotating clamping.

[0104] The working principle of the fluid connector in the embodiment includes: as shown in FIG. 6, the first connecting part 21 and the second connecting part 22 in the separated state are close to each other along the preset direction X until the specific end of the two connecting parts 2 abuts (i.e., the abutting end abuts), specifically, the valve 4 of the two connecting parts 2 abuts, and in this process, the clamping hook 51 extends into the clamping groove 52 along the preset direction X to reach the state shown in FIG. 7.

[0105] The forward rotating operation part 1 drives the valve 4 of the first connecting part 21 to rotate, and in this process, the clamping hook 51 is clamped with the clamping groove 52, and the valve 4 of the first connecting part 21 and the valve 4 of the second connecting part are both completed to open the corresponding communication channel 31, to enter the state shown in FIG. 8, and in this process, specifically, after the clamping hook 51 is clamped with the clamping groove 52, the valve 4 of the first connecting part 21 and the valve 4 of the second connecting part 22 start to open the corresponding communication channel 31.

[0106] When the two connecting parts 2 need to be separated, the operation part 1 is reversely rotated to drive the valve of the first connecting part 21 and the valve of the second connecting part 22 to complete the closing of the corresponding communication channel 31, and then the operation part 1 is continuously rotated, the clamping hook 51 and the clamping groove 52 are relatively moved until the clamping hook 51 can be pulled out of the clamping groove 52 along the preset direction X, and the two connecting parts 2 can also be separated.

[0107] In addition, in other embodiments, the connecting part 2 in the fluid connector can also be more than two, for example, three, for example, the valve 4 of each connecting part 2 can be connected with a gear transmission structure and extended through the corresponding valve seat 3 to abut together to form a structure similar to a three-way structure when the three connecting parts 2 are abutted together, and the operation part is simultaneously engaged with the gear transmission structure on each valve 4 to drive.

[0108] In addition, in other embodiments, the valve 4 of the connecting portion 2 can also be driven to move relative to the corresponding valve seat 3 to open and / or close the corresponding communication passage 31 in the state that the operation portion 1 is abutted against the at least two connecting portions 2. For example, when the connecting portions 2 are kept in the separated state with a spacing as shown in FIG. 6, the operation portion 1 can be detachably connected to the valve 4 of each connecting portion 2 to uniformly control the opening and closing of each valve 4. For example, the operation portion 1 includes different telescopic supporting rods, each of which is connected to a different valve 4 and can be synchronously telescoped, and the valve 4 is driven to move relative to the corresponding valve seat 3 by the telescoping of the telescopic supporting rod. In this way, the connecting portions 2 can be applied to the production and quality inspection processes, the fluid is simultaneously introduced into each connecting portion, the sealing performance is detected by simultaneously opening and closing different communication passages 31, and the production and quality inspection efficiency can be improved.

[0109] In addition to the fluid connector described above, the application also provides a connecting end of a fluid connector, specifically, the assembly structure of the operation portion 1 and one of the connecting portions 2 in each of the embodiments described above, and the other related structures and beneficial effects can be referred to the above embodiments.

The sleeve 11 is movably (for example, rotationally connected) sleeved on the outside of the valve seat 3 and is in transmission connection with the valve 4.

[0111] The connecting portion 2 of the first connecting end 23 can be abutted against other connecting ends of the fluid connector. In this embodiment, the other connecting end of the fluid connector is a second connecting end 24, and the structure of the second connecting end 24 can be the same as that of the connecting portion 2 of the first connecting end 23 or the second connecting portion 22 described above.

[0112] In this embodiment, by abutting against each other, the sleeve 11 is in transmission connection with the valve 4 of the second connecting end 24, so that the sleeve 11 is driven to move relative to the corresponding valve seat 3 to open and / or close the corresponding communication passage 31.

[0113] Further, in the connecting portion of the first connecting end 23, the valve 4 is provided with a locking structure 5, the communication passage 31 and the locking structure 5 are located on the two sides of the valve 4, respectively, and the locking structure 5 is used to lock the valve 4 on the connecting portion and the valve 4 on the second connecting end 24.

[0114] Further, the locking structure 5 is a clamping hook 51 used to clamp and lock a clamping groove 52 on the valve 4 of the second connecting end 24.
