[0053] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0054] The core of the utility model is to provide a fluid connector and a connecting end of the fluid connector, which can improve the use efficiency of the fluid connector.

[0055] For a specific embodiment of the fluid connector provided by the present utility model, please refer to Figures 1 to 11The fluid connector mainly includes an operating part 1 and at least two connecting parts 2, specifically two connecting parts 2, namely a first connecting part 21 and a second connecting part 22.

[0056] like Figure 1 and Figure 4 As shown, the connecting part 2 mainly includes a valve seat 3 and a valve 4. The valve 4 is movably arranged on the valve seat 3 to open and close a communication channel 31 on the valve seat 3. It can be understood that the valve seat 3 is provided with a communication channel 31 for fluid circulation.

[0057] The connecting passages 31 of the two connecting parts 21 can be straight-line passages, and at least one of them can also be a curved passage. One end of the connecting passage 31 is used to connect with the connecting passage 31 on the other connecting part 2, and the other end can be used to connect to an external pipeline or other passage structure.

[0058] Among them, the valve 4 controls the opening and closing of the communication channel 31, specifically, as follows Figure 1 As shown, in at least one connection part 2, on the valve 4, there is a connecting hole 41, that is, the valve 4 is provided with a connecting hole 41 for fluid circulation. When the valve 4 moves relative to the valve seat 3, the opening and closing of the connecting channel 31 is controlled by changing the connection and stagger between the connecting hole 41 and the connecting channel 31. Specifically, when the connecting hole 41 is completely staggered with the corresponding connecting channel 31, the corresponding connecting channel 31 can be closed or closed, so that the fluid cannot pass through the connecting channel 31; otherwise, the connecting hole 41 is connected to the connecting channel 31, and the connecting channel 31 is opened (partially opened or fully opened). Generally, the connecting hole 41 and the connecting channel 31 are aligned, such as coaxially arranged, and the opening effect of the connecting channel 31 is better. It can be understood that the shape and size of the connecting hole 41 and the connecting channel 31 should be roughly the same, or even completely the same, to achieve a better connection effect. Of course, the valve 4 may not form the above-mentioned connecting hole 41. In this case, the valve 4 acts as a physical structure: when it moves to the connecting channel 31, it blocks one end of the connecting channel 31 to close or disconnect the connecting channel 31; and when it avoids the connecting channel 31, it opens or opens the corresponding end of the connecting channel 31 to open the connecting channel 31.

[0059] The operating part 1 can be transmission-connected with the valves 4 on each connecting part 2. For example, the operating part 1 can be transmission-connected with different valves 4 respectively, and there is no need to transmit the movement or force of the operating part 1 between the valves 4 of different connecting parts 2; or, when the operating part 1 is active, there is a valve 4 as an intermediate transmission member, that is, the operating part 1 can be transmission-connected with the valve 4 of another connecting part 22 through the valve 4 of one connecting part 2. At this time, the movement or force of the operating part 1 can be transmitted to the valve 4 of the previous connecting part 2, and needs to be transmitted to the valve 4 of the next connecting part 22 through the valve 4 of the previous connecting part 2.

[0060] In the state where the two connecting parts 2 are against each other, when the operating part 1 is moved, the operating 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 channel 31. In the state where at least two connecting parts 2 are against each other, for example, at least two connecting parts 2 are against each other in pairs or against each other in pairs, when the operating part 1 is moved, the valve 4 on at least two connecting parts 2 can be driven to move relative to the corresponding valve seat 3, so as to open and / or close the corresponding communication channel 31.

[0061] Specifically, driven by the operating part 1, when one connecting channel 31 opens, the other connecting channels 31 also open or are about to open; correspondingly, when one connecting channel 31 closes, the other connecting channels 31 also close or are about to close.

[0062] It should be noted that the opening and closing here refer to the ability to open the communication channel 31 or to close the communication channel 31, and the ability to switch between the two, rather than achieving both the opening and closing states at the same time. Figure 7 and Figure 8 , Figure 7 Under the drive of the operating part 1, the communication channels 31 of the two connecting parts 2 are both in a closed state. At this time, the fluid in the communication channel 31 in one connecting part 2 cannot flow into the communication channel 31 in the other connecting part 2 due to the obstruction of the valves 4 of the two connecting parts 2. Figure 8 Driven by the operating part 1 , the connecting channels 31 of the two connecting parts 2 are opened, so that the corresponding connecting channels 31 of the two connecting parts 2 are in a connected state. At this time, the fluid in the connecting channel 31 of one connecting part 2 can flow into the corresponding connecting channel 31 of the other connecting part 2 .

[0063] It should be noted that, unless otherwise specified, components having a corresponding relationship are located in the same connecting portion 2 .

[0064] Among them, the transmission between the operating part 1 and the valve 4 can be carried out by connecting rod connection, magnetic force transmission, gear transmission, etc. according to needs; the transmission path can be selected: transmission between each valve 4 in sequence, and transmission between the operating part 1 and one of the valves 4; transmission between the operating part 1 and each valve 4 one by one.

[0065] Among them, for the state where at least two connecting parts 2 are against each other, it is usually that the set docking ends of different connecting parts 2 are against each other, wherein each connecting part 2 may have one or at least two docking ends, and the docking ends are usually related to the inflow or outflow position of the fluid in the connecting part 2. For example, in this embodiment, the valve 4 in the connecting part 2 is set at one end of the valve seat 3, and the docking ends of the two connecting parts 2 are against each other, which means that one end of the two connecting parts 2 where the valve 4 is set is against each other, and more specifically, the valves 4 of the two connecting parts 2 can be against each other. In other embodiments, the valve 4 in the connecting part 2 can be centrally arranged on the valve seat 3, and then the docking ends of the two connecting parts 2 are against each other, which can be the set positions on the valve seats 3 of the two connecting parts 2. Usually, when the fluid passes through the fluid connector, the fluid flows out from the previous connecting part 2 through its docking end, enters the docking end of the next connecting part 2, and then continues to flow in the next connecting part 2.

[0066] Of course, in other embodiments, the movement of the operating portion 1 may only open the communication passages 31 of the two connection portions 2 but not close them, or only close the communication passages 31 of the two connection portions 2 but not open them.

[0067] In this embodiment, an operating part 1 is added. By adjusting the movement of the operating part 1, the valves 4 in different connecting parts 2 can be driven to move, thereby adjusting the opening and / or closing of different connecting channels 31, thereby improving the use efficiency of the fluid connector.

[0068] To realize the assembly and disassembly between the two connecting parts 2, as Figure 7 and Figure 8 As shown, the operating part 1 also drives the connecting locking structure 5. When the two connecting parts 2 are in abutment with each other, when the operating part 1 moves, the operating part 1 can drive the locking structure 5 to move, so that the two connecting parts 2 can be locked and disconnected. Here, it means that the operating part 1 can drive the locking structure 5 to lock, and can also achieve disconnection, and can switch between the two, rather than locking and disconnecting at the same time. Of course, in other embodiments, the operating part 1 can also only drive the locking structure 5 to lock the two connecting parts 2, but cannot drive the locking structure 5 to disconnect the two connecting parts 2, or can only drive the locking structure 5 to disconnect the two connecting parts 2, but cannot drive the locking structure 5 to lock the two connecting parts 2.

[0069] It should be noted that the two connecting parts 2 are locked, which specifically refers to that the relative positions of the valve seats 3 of the two connecting parts 2 are determined to ensure the smooth flow of the fluid between the two connecting parts 2, and the position of the valve 4 relative to the corresponding valve seat 3 can be changed, for example, driven by the operating part 1, so that the valve 4 opens and closes the corresponding communication channel 31; the two connecting parts 2 are closed, which specifically refers to that the two connecting parts 2 can be separated, such as Figure 6As shown, the two connecting parts 2 can be in a split state and move independently. In addition, locking can also be interpreted as different connecting parts 2 being limited in the opposite direction of the docking direction, so that when they are against each other in the docking direction, they can be locked to avoid moving away from each other in the opposite direction of the docking direction; while disconnection, that is, unlocking, at this time, different connecting parts 2 are no longer limited in the opposite direction of the docking direction, and can move away from each other in the opposite direction of the docking direction to be separated.

[0070] In this embodiment, in addition to being able to control the opening and closing of the valve 4 with respect to the corresponding connecting channel 31, the operating part 1 also has the function of controlling the assembly and disassembly of the two connecting parts 2, thereby realizing the multifunctionality of the operating part 1. At the same time, in assembling different connecting parts 2 and adjusting the opening and closing of the connecting channel 31, only the operating part 1 needs to be adjusted, thereby unifying the user's operating position.

[0071] Of course, in other embodiments, the movement of the operating part 1 can be used to drive the movement of the valve 4 to open and close the communication channel, and / or can be used to drive the locking structure 5 to lock and / or unlock. The above two methods can exist separately in one embodiment. In some specific embodiments, when the movement of the valve 4 to open and close the corresponding communication channel 31 needs to be achieved by rotation, or when the locking and unlocking of the locking structure 5 need to be achieved by rotation, the above technical effects can be achieved by setting a separate operating part 1, that is, avoiding the relative rotation of the valve seats 3 of the connecting part through the docking, and realizing the above structure.

[0072] Alternatively, in other embodiments, the locking structure 5 may not be connected to the operating part 1. For example, the locking structure 5 may be a magnetic structure or a snap-on structure directly fixed on the valve seats 3 of the two connecting parts 2, and the two connecting parts 2 are directly and detachably connected through the locking structure 5 to achieve locking and / or disconnection of the two connecting parts 2. Alternatively, the locking structure 5 is an independent locking rod that is equally separated from the operating part 1 and the connecting part 2. By respectively 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 detachably inserted into the locking holes corresponding to the two connecting parts 2 at the same time, so that the two connecting parts 2 can be locked and / or disconnected. 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.

[0073] In order to improve the operating efficiency of the operating part 1, in a preset operating action of the operating part 1, the valve 4 is moved to open the corresponding communication channel 31, and the locking structure 5 is locked; and in the reverse operation process of this preset operating action or other operating actions, the valve 4 is moved to close the corresponding communication channel, and the locking structure 5 is unlocked. The movement of the valve 4 to open the communication channel 31 and the locking structure 5 are not required to be performed synchronously, and can be staggered, synchronous, partially synchronous, and partially staggered. Moreover, under different conditions, the order of the movement can be passively or actively adjusted. The movement of the valve 4 to close the corresponding communication channel 31 and the unlocking of the locking structure 5 can also be set as above, and are not subject to the above restrictions.

[0074] It should be noted that the preset operation stroke is intended to facilitate operation, such as a single sliding, rotating, spiral movement, etc., whichever is more specific to achieve the above effects. The above other operation actions are, for example, the continuation of the above preset operation actions.

[0075] Specifically, Figure 7 and Figure 8 As shown, when the two connecting parts 2 are in abutment with each other, the operating part 1 moves, 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 channels 31 of the two connecting parts 2. In other words, the locking of the two connecting parts 2 by the operating part 1 and the opening of the corresponding communication channels 31 are performed sequentially.

[0076] For the sequential method, Figure 7 The state shown in which the two connecting parts 2 are butted against each other is the initial state. At this time, when the two connecting parts 2 are just butted against each other, the two connecting parts 2 have no connection relationship and can still be separated freely, and the valve 4 closes the corresponding connecting channel 31. The operating part 1 is driven to move by external force, and the operating part 1 drives the locking structure 5 to move, so that the two connecting parts 2 are connected together, and the locking structure 5 reaches the set locking position, completing the locking process. At this time, each connecting channel 31 can be in a closed state. Afterwards, the operating part 1 continues to be driven to move (specifically, it can move in the original direction, such as always rotating clockwise, or always translating in the set direction, and in other embodiments, it can also change direction and continue to move), and the two valves 4 open the corresponding connecting channels 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, and the connecting channels 31 of the two connecting parts 2 are in a closed state. Figure 8 The connecting state of the valve 4, wherein the valve 4 completing the opening action means that the valve 4 moves to the position where the corresponding connecting channel 31 is least blocked, and at this time, the connecting channel 31 is fully opened.

[0077] In another embodiment, when the two connecting parts 2 are in abutment with each other, when the operating part 1 moves, 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 channels 31 of the two connecting parts 2. That is to say, in this embodiment, the locking of the two connecting parts 2 by the operating part 1 and the opening of the corresponding communication channels 31 are performed crosswise.

[0078] For the cross-operation method, in the initial state where the two connecting parts 2 are against each other, the valve 4 closes the corresponding communication channel, and in the locking process (for example, when the locking structure 5 starts to lock, or when the locking structure 5 has moved and moved to a position before the set locking position), the valve 4 of at least one connecting part 2 also opens the corresponding communication channel 31 along with the operating part 1. Among them, the valves 4 of the two connecting parts 2 can start the opening action at the same time, or can start the opening action in sequence, 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 at the same time, or at least one valve 4 has not completed the opening action, and the operating part 1 continues to control the activity until the valves 4 of the two connecting parts 2 complete the opening action, so that the communication channel 31 of the first connecting part 21 and the communication channel 31 of the second connecting part 22 are connected.

[0079] In terms of use effect, the sequential method has a better anti-leakage effect because the valve 4 always closes the corresponding communication channel 31 before the two connecting parts 2 are locked, especially when there is fluid in the connecting part 2. If the external device of the connecting part 2 has not been started and the connecting parts 2 have not entered the fluid, the cross-processing method is more efficient.

[0080] Of course, in other embodiments, if the action of the operating part 1 driving the valve 4 to open the corresponding connecting channel 31 precedes the action of the operating part 1 driving the two connecting parts 2 to lock, an external sealing structure may be required between the two connecting parts 2 to assist in avoiding fluid leakage of the connecting parts 2.

[0081] In addition, in the process of the operating part controlling the two connecting parts 2 to disconnect and driving the two valves 4 to close the corresponding connecting channels 31, the locking structure 5 can be made to disconnect after driving the valves 4 of the two connecting parts 2 to close the corresponding connecting channels 31 synchronously or asynchronously; or, the locking structure 5 can be made to disconnect after only driving one of the valves 4 to close the corresponding connecting channel 31; or, the locking structure 5 can only be made to disconnect after the valves 4 of the two connecting parts 2 cannot be made to close the corresponding connecting channels 31.

[0082] To facilitate processing and ensure the reliability of the connection, the locking structure 5 is specifically a snap-fit ​​structure, which may include a hook 51 arranged on the valve 4 or the valve seat 3 of the first connecting part 21, and correspondingly, a slot 52 that cooperates with the hook 51 is correspondingly arranged on the valve 4 or the valve seat 3 of the second connecting part 22.

[0083] Among them, when the specific ends (i.e., the docking ends) of the first connecting portion 21 and the second connecting portion 22 are in abutment with each other, the two are arranged in sequence along the preset direction X. Specifically, the two connecting portions 2 can be snap-fitted after being abutted with each other; in other embodiments, the snap-fitting structure can also be snap-fitted when the two connecting portions 2 are approaching each other along the preset direction X, and the snap-fitting is completed when they are abutted with each other.

[0084] To further facilitate assembly, Figure 1 , Figure 2 and Figure 6 As shown, the operating part 1 is arranged on the first connecting part 21, and can be specifically arranged on the valve seat 3 of the first connecting part 21. The first connecting part 21 and the operating part 1 constitute a first connecting end 23; the second connecting part 22 constitutes a second connecting end 24. During the assembly process, the operating part 1 and the first connecting part 21 do not need to be assembled separately, and the loss of the operating part 1 can be avoided. Of course, in other embodiments, the operating part 1 is a separate component independent of the two connecting parts 2.

[0085] To facilitate the control of the operating unit 1, Figure 7 and Figure 8 As shown, when the two connecting parts 2 are in contact with each other, at least part of the structure of the operating part 1 is exposed from one of the connecting parts 2. This exposed part can be used as a driving part so that a user or an external device can apply external force to the operating part 1 to move the operating part 1.

[0086] Specifically, Figure 1 As shown, the operating part 1 includes a sleeve 11 sleeved on the outside of the valve seat 3 of the first connecting part 21, and a control hole 2 is arranged on the valve seat 3 of the first connecting part 21. The operating part 1 can be connected to the valve 4 in the first connecting part 21 at the control hole 2 through a transmission structure such as a connecting rod 42, and the operating part 1 drives the valves 4 of the two connecting parts 2 to move by rotation or translation. Of course, in other embodiments, the operating part 1 can also be other structures, for example, the above-mentioned sleeve 11 is eliminated, and the connecting rod 42 connected between the sleeve 11 and the valve 4 is directly used as the operating part.

[0087] In order to improve the regulation efficiency, in the state where the two connection parts 2 are against each other, the two connection parts 2 are arranged in sequence along the preset direction X, and the operating part 1 is rotatably connected to the first connection part 21, specifically, rotatably sleeved on the outer side of the valve seat 3 of the first connection part 21, wherein the rotation axis of the operating part 1 is parallel to the preset direction X. The operating part 1 opens the communication channel 31 of the two connection parts 2 and enables the locking structure 5 to lock the two connection parts 2 by rotating in one direction, that is, always rotating clockwise or always counterclockwise, so that the operating part 1 only needs to be operated in one direction, thereby further improving the regulation efficiency of the valve 4 and the locking structure 5.

[0088] When the operating part 1 rotates, the valve 4 in the first connecting part 21 can rotate synchronously with the operating part 1, and at a certain moment (starting moment or intermediate moment) during the rotation 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, wherein the rotation axes of the valves 4 of the two connecting parts 22 can also be parallel to the preset direction X, and the synchronization of the movement can also facilitate determining the positions of the two valves 4 in the corresponding valve seats 3 through the position of the operating part 1.

[0089] In addition, in other embodiments, the operating part 1 may not have an exposed part, but may be built into one of the connecting parts 2, for example, built into the first connecting part 21. In this case, the operating part 1 is usually required to have good waterproof performance, and may specifically include an electric control power structure (for example, a motor). Specifically, the operating part 1 in the first connecting part 21 is connected to 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 respectively connected to the valve 4 and the locking structure 5 by transmission), and the locking structure 5 may be connected to the valve seat 4 of the first connecting part 21. When the two connecting parts 2 are against each other, the operating part 1 in the first connecting part 21 and the valve 4 in the second connecting part 22 are connected by transmission through plugging, clamping, etc. The operating part 1 receives the command of the external device through wireless communication such as Bluetooth, drives the locking structure 5 to clamp or clamp the valve seat 3 of the second connecting part 21, and realizes 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 movements.

[0090] To realize the transmission of the two valves 4 by the operating part 1, as Figure 1 and Figure 4 As shown, the operating part 1 is connected to the valve 4 in the first connecting part 21, and a locking structure 5 is arranged between the valves 4 of the two connecting parts 2. At this time, in addition to having a locking capability, the locking structure 5 can also 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.

[0091] In the process of opening the communication channel 31, when the first connection part 21 and the second connection part 22 are in abutment with each other, the operating part 1 is active, which can drive the valve 4 in the first connection part 21 to move, and the operating part 1 can sequentially drive the valve 4 in the second connection part 22 to move through the valve 4 in the first connection part 21 and the locking structure 5 to open the communication channel 31 of the two connection parts 2. In addition, the locking action of the locking structure 5 can be performed before or during the opening action of each valve 4, or after each valve 4 has completed the opening action. As for the process of closing the communication channel 31 of the two connection parts 2, it can be performed in the locked state of the two connection parts 2, or in the process of disconnecting the two connection parts 2.

[0092] In addition, during the locking process, when the two connecting parts 2 are in contact with each other, the operating part 1 moves, which can drive the valve 4 in the first connecting part 21 to move. During this process, the valve 4 in the second connecting part 22 can remain stationary relative to the corresponding valve seat 3, thereby allowing the locking structure 5 to lock the valve 4 in the first connecting part 21 and the valve 4 in the second connecting part 22.

[0093] Regarding the specific structural arrangement of the connecting part 2 and the operating part 1, as shown in FIG. Figures 1 to 3 As shown, in the first connecting portion 21, the valve 4 is rotatably connected to the valve seat 3, a control hole 32 is provided on the valve seat 3, and the valve 4 is connected to the operating 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 operating portion 1.

[0094] The operating part 1 includes a sleeve 11 that is rotatably sleeved outside the valve seat 3, and the first transmission structure includes a connecting rod 42 that is fixedly connected to the operating part 1 and the valve 4 at both ends. The valve 4 is driven to rotate synchronously by the rotation of the sleeve 11. In addition, the sleeve 11 also has the advantage of shielding the control hole 32. Optionally, when the operating part 1 is at any position within its movable range, the operating part 1 always covers the control hole 32, which can reduce the entry of foreign objects (including dust and other foreign dirt) into the control hole 32, thereby reducing the direct contact or collision of foreign objects with the valve 4 or entering the interior of the connecting part 2 through the control hole 32, thereby reducing the influence of the control hole 22 on the normal use of the fluid connector. In addition, the sleeve 11 can also protrude from one end of the valve seat 3 of the first connecting part 21, and when the two connecting parts 2 are against each other, the sleeve 11 can shield the docking position of the two connecting parts 2 to improve the shielding ability. In addition, in other embodiments, the operating part 1 may be a baffle, such as a rectangular piece; or, the operating part 1 may be a knob, which drives the valve 4 to rotate or move through a gear transmission structure.

[0095] In the second connection part 22, the valve 4 is also connected to the valve seat 3 in rotation. When the specific ends (i.e., the butt ends) of the two connection parts 2 are butted against each other, the arrangement direction of the two connection parts 2 is the preset direction X, and the rotation axis of the valve 4 in each connection part 2 relative to the valve seat 3 can be parallel to the preset direction X. Alternatively, in the first connection part 21 or the second connection part 22, the valve 4 and the valve seat 3 can also be connected in a movable manner by translation, for example, the valve 4 is specifically a baffle structure, and can be connected to the valve seat 3 in a translational manner, and the opening and closing control is realized by blocking or opening one end of the communication channel 31.

[0096] Regarding the specific structural setting of the locking structure 5, when it is a clamping structure and connected between the valves 4 of the two connecting parts 2, as shown in FIG. Figure 1 and Figure 4 As shown, the clamping structure may specifically include a clamping hook 51 fixed on the valve 4 of the first connection part 21, and a clamping groove 52 is provided on the other, that is, the clamping groove 52 is provided on the valve 4 of the second connection part 22. Of course, in other embodiments, the clamping hook 51 may also be provided on the valve 4 of the second connection part 22, and the clamping groove 52 may be provided on the valve 4 of the first connection part 21.

[0097] Among them, the setting positions of the hook 51 and the slot 52 are as follows: Figure 1 As shown, in the first connection part 21, the valve 4 is located on one side of the communication channel 31 in the preset direction X, and the other side is used to fix the hook 51 to connect the second connection part 22. Figure 4 As shown, in the second connecting portion 22 , the valve 4 is located at one side of the communicating channel 31 , and a clamping groove 52 is provided on the valve 4 .

[0098] Among them, for the specific structure of the card slot 52, such as Figures 9 to 11 As shown, the slot 52 is an L-shaped slot, including a first slot body 521 extending along a preset direction X and a second slot body 522 having an angle with the first slot body 521. The first slot body 521 and the second slot body 522 can be vertically arranged, and the second slot body 522 is located on one side of the first slot body 521 in the circumferential direction (corresponding to the circumferential direction of the rotation axis of the valve 4).

[0099] Among them, for the specific structure of the hook 51, such as Figure 1 , Figures 9 to 11 As shown, the hook 51 includes a rod 511 fixed to the valve 4 and a hook 512 fixed to the rod 511 , and the hook 512 is located on one side of the rod 511 in the circumferential direction (corresponding to the circumferential direction around the rotation axis of the valve 4 ).

[0100] When the hook 51 and the slot 52 are assembled and disassembled, the hook 51 can first enter the first slot 521 along the preset direction X. Fig. 9As shown, the first groove 521 can accommodate the entire hook 51 until the two valves 4 abut against each other, and then, as shown in FIG. Fig.10 As shown, the operating part 1 moves, driving the valve 4 of the first connecting part 21 to move, so that the hook-shaped part 512 of the hook 51 enters the second groove 522 .

[0101] Of course, in other embodiments, the slot 52 may also include an accommodating through hole for the valve 4 that passes through the second connecting portion 22 along a preset direction X, and the hook 51 may pass through the accommodating through hole, and there is a gap between the valve 4 of the second connecting portion 22 and the valve seat 3 for accommodating the hook-shaped portion 512 of the hook 51. When locked, the hook-shaped portion 512 of the hook 51 enters the gap and hooks the side of the valve 4 close to the connecting channel 31.

[0102] In addition, the operating part 1 moves, driving the valve 4 of the first connecting part 21 to move, so that during the process of the hook-shaped part 512 of the hook 51 entering or escaping from the second groove body 522, the valve 4 of the second connecting part 22 needs to have relative movement with the hook 51, which can be achieved by setting a starting limit structure and an end limit structure between the valve 4 in the second connecting part 22 and the valve seat 3.

[0103] For example, a positioning groove 53 is provided on one of the valve 4 and the valve seat 3, and a protrusion 54 is provided on the other, and the positioning groove 53 is buckled on the protrusion 54 along a preset direction X, so that when the force applied to the operating part 1 is less than a set value, the relative position of the valve 4 and the valve seat 3 in the second connecting part 22 remains unchanged until the force reaches Fig.10 Then, by increasing the external force applied to the operating portion 1, the projection 54 and the positioning groove 53 are offset, as shown in FIG. Fig.11 As shown, the valve 4 of the first connection part 21 drives the valve 4 of the second connection part 22 to move through the locking structure 5. In addition, a soft sealing pad, such as a rubber pad, can be provided in one of the valve 4 of the second connection part 22 and the valve seat 3 in which the positioning groove 53 is provided. The positioning groove 53 is provided on the sealing pad, so that after the positioning groove 53 is staggered with the protrusion 54, the protrusion 54 can squeeze the sealing pad to move, and the movement of the protrusion 54 will not cause structural damage.

[0104] 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 to make the operating part 1 move in the opposite direction. At this time, the valve 4 and the slot 52 of the second connecting part 22 remain stationary, and the hook 51 can directly escape from the second slot body 522 to achieve disconnection. That is to say, at this time, the operating part 1 cannot drive the valve 4 of the second connecting part 22 to close the connecting channel 31 of the second connecting part 22. The position of the valve 4 of the second connecting part 22 can be manually adjusted after the first connecting part 21 is separated from the second connecting part 22.

[0105] Alternatively, the initial limit structure may be configured in other ways. For example, in the second connection portion 22, one of the valve 4 and the valve seat 3 is provided with a slide groove, and the other is provided with a slider, so as to respectively limit the two extreme positions at which the valve 4 can rotate relative to the valve seat 3 in two directions. At this time, the operating portion 1 drives the valve 4 of the first connection portion 21 to move, so that during the process that the hook-shaped portion 512 of the hook 51 enters the second groove body 522, the hook 51 can push the valve 4 of the second connection portion 22 to move before entering the second groove body 522 or in the middle position, and the slider is relatively The slider moves in the slide groove until the slider abuts against one end of the slide groove, then the valve 4 of the second connecting part 22 stops moving, and the hook 51 can continue to enter the second groove body 522. Alternatively, the hook 51 can completely enter the second groove body 522 and then push the valve 4 of the second connecting part 22 to move until the slider abuts against one end of the slide groove. At this time, the slider and the slide groove constitute a starting limit structure, and when they abut against each other, the valve 4 of the second connecting part 22 fully opens the corresponding connecting channel 31, and the valve 4 of the first connecting part 21 can fully open the corresponding connecting channel 31.

[0106] At this time, for the disassembly process, that is, the disconnection process of the locking structure 5, the operating part 1 drives the valve 4 to move in the opposite direction, and the hook 51 and the slot 52 can maintain synchronous movement with the help of friction, so that the valve 4 of the first connecting part 21 and the valve 4 of the second connecting part 22 both move to close the corresponding connecting channel 31. During this process, the slider and the slot also move relatively. When the slider and the other end of the slot are against each other, the slider and the slot form an end limit structure. The valve 4 of the second connecting part 22 closes the connecting channel 31 of the second connecting part 22, and the valve 4 of the first connecting part 21 closes or partially opens the connecting 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 operating part 1 can drive the hook 51 to continue to move in the second slot body 522 until it can be disengaged from the first slot body 521 along the preset direction X to complete the disconnection process. When completed, the valve 4 of the first connecting part 21 can close the corresponding connecting channel.

[0107] Of course, in other embodiments, the locking structure 5 can also be directly provided on the operating part 1, and the operating part 1 is provided on the first connecting part 21. When the two connecting parts 2 are in abutment with each other, the operating part 1 is locked in position relative to the first connecting part 21 in a preset direction X. Specifically, it can be achieved by clamping with the first connecting part 21 along this direction, and the locking structure 5 can be clamped with the valve seat 3 of the second connecting part 22. For example, the locking structure 5 is an elastic clamping block, which is elastically deformed perpendicular to the preset direction X and clamped to the groove on the outer surface of the valve seat 3 of the second connecting part 22 to lock the first connecting part 21 and the second connecting part 22.

[0108] In addition, in other embodiments, the locking structure 5 can also be arranged between the valve seat 3 of one connecting part 2 and the valve 4 of the other connecting part 2, or between two docking connecting parts 2, or between two specific structures that rotate relative to each other during the docking process, so as to achieve rotational locking.

[0109] The working principle of the fluid connector in this embodiment includes: Figure 6 As shown, the first connection part 21 and the second connection part 22 in the separated state approach each other along the preset direction X until the specific ends of the two connection parts 2 abut against each other (i.e., the butt ends abut against each other), specifically, the valves 4 of the two connection parts 2 abut against each other, wherein, during this process, the hook 51 extends into the slot 52 along the preset direction X, reaching Figure 7 The status shown;

[0110] The operating part 1 is rotated forward, and the operating part 1 drives the valve 4 of the first connecting part 21 to rotate. During this process, the hook 51 is engaged with the slot 52, and the valve 4 of the first connecting part 21 and the valve 4 of the second connecting part are both opened, and the valve 4 of the first connecting part 21 and the valve 4 of the second connecting part are opened. Figure 8 In the state shown, in this process, specifically, after the hook 51 is engaged with the slot 52, the valve 4 of the first connection part 21 and the valve 4 of the second connection part 22 begin to open the corresponding communication channel 31;

[0111] When the two connecting parts 2 need to be separated, the operating part 1 is rotated in the opposite direction to drive the valve of the first connecting part 21 and the valve of the second connecting part 22 to complete closing the corresponding connecting channel 31. After that, the operating part 1 is continued to be rotated, and the hook 51 and the slot 52 move relative to each other until the hook 51 can escape from the slot 52 along the preset direction X, and the two connecting parts 2 can also be separated.

[0112] In addition, in other embodiments, the connection parts 2 in the fluid connector may be more than two, for example, three. For example, the valve 4 of each connection part 2 may be connected to a gear transmission structure and extend through the corresponding valve seat 3 to dock the three connection parts 2 together to form a structure similar to a tee, and the operating part is simultaneously engaged with the gear transmission structure on each valve 4 for transmission.

[0113] In addition, in other embodiments, the operating part 1 may drive the valves 4 of at least two connecting parts 2 to move relative to the corresponding valve seats 3 when at least two connecting parts 2 are in contact with each other, so as to open and / or close the corresponding communication channels 31. Figure 6When the operating part 1 is in the separated and spaced state shown, the operating part 1 can be detachably connected to the valves 4 of each connecting part 2 to uniformly control the opening and closing of each valve 4. For example, the operating part 1 includes different telescopic rods, each of which is connected to a different valve 4 and can be retracted synchronously, and the valve 4 is driven to move relative to the corresponding valve seat 3 by the extension and retraction of the telescopic rod. This method can be applied to the production and quality inspection process of the connecting part 2, and fluid is introduced into each connecting part at the same time, and the sealing and other performances are tested by opening and closing different connecting channels 31 at the same time, which can improve the production and quality inspection efficiency.

[0114] In addition to the above-mentioned fluid connector, the present invention also provides a connection end of a fluid connector, specifically an assembly structure of the operating part 1 and one of the connection parts 2 in the above-mentioned embodiments. The arrangement and beneficial effects of other related structures can refer to the above-mentioned embodiments.

[0115] The connection end is the first connection end 23, the operating part 1 is specifically a sleeve 11, the connection part 2 includes a valve seat 3 and a valve 4, and the valve 4 is movably arranged on the valve seat 3 to open and close the communication channel 31 on the valve seat 3. The sleeve 11 is movably (for example, rotatably connected) sleeved on the outside of the valve seat 3 and is drivingly connected to the valve 4.

[0116] The connection portion 2 of the first connection end 23 can be abutted against the other connection end of the fluid connector. The other connection end in the fluid connector is a second connection end 24, and the structure of the second connection end 24 can be the same as that of the connection portion 2 in the first connection end 23, or can be the second connection portion 22 mentioned above.

[0117] Among them, through the above-mentioned offset, the sleeve 11 and the valve 4 of the second connecting end 24 can also be transmission-connected, so that through the movement of the sleeve 11, the connecting part 2 and the valve 4 on the second connecting end 24 are driven to move relative to the corresponding valve seat 3, so that the corresponding connecting channel 31 is opened and / or closed.

[0118] Furthermore, in the connection portion of the first connection end 23: a locking structure 5 is provided on the valve 4, the communication channel 31 and the locking structure 5 are respectively located on both sides of the valve 4, and the locking structure 5 is used to lock the valve 4 on the connection portion with the valve 4 on the second connection end 24.

[0119] Furthermore, the locking structure 5 is a hook 51 for engaging and locking a groove 52 on the valve 4 on the second connection end 24 .
