[0035] 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 protection of the present application.

[0036] The core of the present application is to provide a connecting end of a fluid connector and a fluid connector, which can more conveniently perform opening and closing operation of a communication channel.

[0037] In a specific embodiment of the connecting end of the fluid connector provided by the present application, please refer to FIG. 1 to FIG. 5. The connecting end includes a connecting part 18 and an operation part 11.

[0038] As shown in FIG. 1 and FIG. 2, the connecting part 18 includes a valve seat 12 and a valve 13 movably connected to the valve seat 12. The valve seat 12 is provided with a communication channel 16 for fluid to pass through. The valve 13 is moved (for example, rotated or moved along a set direction) on the valve seat 12 to open or close the communication channel 16, thereby realizing opening and closing of the communication channel 16 on the connecting part 18.

[0039] The valve 13 is rotationally connected to the valve seat 12. For its rotation axis, specifically, the valve 13 is arranged on one side or middle part of the communication channel 16 in a preset direction. The valve 13 is rotationally connected to the valve seat 12, and the rotation axis of the valve 13 extends along the preset direction. In addition, the communication channel 16 can also extend along the preset direction, which is a straight channel. In other embodiments, it can also be a bent channel.

[0040] More specifically, as shown in FIG. 5, the rotation axis of the valve 13 is parallel to or coincides with the axis O of the connecting part 18. Without special instructions, the axis O of the connecting part 18 is the center line in the direction of connecting to another connecting end. The valve 13 and the communication channel 16 in the connecting part 18 are usually arranged along this direction. This direction can be the preset direction, and the axial direction, the circumferential direction and the radial direction are also based on the axis O.

[0041] In other embodiments, the valve 13 can also be flipped around an axis perpendicular to the preset direction or at other angles.

[0042] As shown in FIG. 1 and FIG. 5, the operation part 11 is movably connected to the outer side of the valve seat 12 for receiving external force to drive the valve 13 to move relative to the valve seat 12. The valve 13 is connected to the operation part 11 through the control hole 15 on the valve seat 12, specifically, the valve 13 can be directly connected to the operation part 11 through the control hole 15, or connected to the operation part 11 through a transmission mechanism. When the operation part 11 is moved, the valve 13 can be driven to move to control the opening and closing of the communication passage 16 on the connecting part 18. It can be understood that the valve 13 can be directly connected to the operation part 11 through the control hole 15, which means that a part of the structure of the valve 13 passes through the control hole 15 and is connected to the operation part 11.

[0043] In the fluid connector in the embodiment, the operation part 11 is arranged outside the valve seat 12, so when the user needs to operate the opening and closing of the communication passage 16, the user can drive the operation part 11 to drive the valve 13 to move, without the need to directly drive the valve seat 12, so that the user can more conveniently operate the opening and closing of the communication passage 31.

[0044] In the embodiment, when the operation part 11 is at any position within its movable range, the operation part 11 always covers the control hole 15, and optionally, the operation part 11 is in sealing cooperation with the control hole 15. The movable range of the operation part 11 refers to the set of positions that the operation part 11 can move to relative to the connecting part 18 based on structural limitations or other settings.

[0045] In the fluid connector in the embodiment, the communication passage 16 can be controlled to be connected or disconnected by driving the operation part 11, and since the operation part 11 can shield the control hole 15, the entry of external objects (including external dirt such as dust) into the control hole 15 can be reduced, so that the external objects can be prevented from directly contacting or impacting the valve 13 through the control hole 15 or entering the inside of the connecting end, thereby reducing the influence of the control hole 15 on the normal use of the fluid connector.

[0046] Further, as shown in FIG. 1, the operation part 11 includes a sleeve arranged outside the valve seat 12, which can ensure the shielding effect of the control hole 15. Of course, in other embodiments, the operation part 11 can be a baffle that shields part of the area around the control hole 15, and when the baffle is moved to any allowed position, the control hole 15 is always shielded.

[0047] In addition, as shown in FIG. 1, the operation part 11 is rotationally connected to the valve seat 12, and specifically can rotate around the axis O of the connecting part 18. At this time, the operation part 11 is rotated relative to the valve seat 12 to drive the valve 13 to move, which is convenient for operation. Of course, in other embodiments, the operation part 11 can also be translated along the axial direction relative to the valve seat 12 to drive the valve 13 to move.

[0048] In addition, at least a part of the sleeve protrudes from the valve seat 12, so that when the connecting portion 18 is connected to the other connecting end of the fluid connector, the protruding part of the sleeve can be sleeved on the other connecting end, so that the sleeve can be shielded at the connection between the other connecting end and the connecting portion 18. In addition, the protruding part of the sleeve can also be a guide portion 111, which is particularly well adapted to the outer surface of the other connecting end of the fluid connector, for example, can be sealingly fitted, or has a small gap, so that during the approach of the other connecting end of the fluid connector and the connecting portion along the predetermined direction X, the guide portion 111 can guide the other connecting end of the fluid connector along the predetermined direction X.

[0049] Further, as shown in FIG. 2, the control hole 15 can be a strip-shaped hole, and the direction in which the operating portion 11 moves relative to the valve seat 12 is along the extension direction of the control hole 15, so as to improve the adaptability of the operating portion 11 and the control hole 15, and to provide sufficient space for the operating portion 11 to connect the valve 13. Specifically, the control hole 15 extends along the circumferential direction, and in other embodiments, the control hole 15 can also extend along the axial direction.

[0050] In addition, as shown in FIG. 2, the valve 13 is fixedly connected to the connecting rod 17, and can be screw-connected or adhesively connected after the valve 13 is installed on the valve seat 12. The connecting rod 17 is fixedly connected to the operating portion 11, and can be adhesively connected or screw-connected after the operating portion 11 is installed on the connecting portion 18. Such a transmission mode is simple in structure, and only the connecting rod 17 is needed to transmit between the operating portion 11 and the valve 13, which is convenient for processing. At this time, the operating portion 11 rotates to drive the valve 13 to rotate. Of course, in other embodiments, other transmission structures can be used to achieve the transmission between the operating portion 11 and the valve 13, for example, a screw-nut assembly, a gear transmission assembly. Specifically, the operating portion 11 can be a knob, which is connected to the valve 13 through a gear transmission mechanism, and the knob rotates to drive the valve 13 to rotate or translate.

[0051] Of course, in other embodiments, there can be a moment or position in the movable range of the operating portion 11 that exposes the control hole 15, for example, the connecting rod 17 in the above embodiment can directly extend out of the valve seat 12, and the extended part can be used as the operating portion 11.

[0052] In addition, the number of control holes 15 can be at least two, as shown in FIGS. 2 and 3, the control holes 15 are uniformly arranged in the circumferential direction, of course, in other embodiments, one, three or other numbers can also be arranged. The operation part 11 is connected to the valve 13 through each control hole 15, the operation part 11 can simultaneously cover each control hole 15, which can reduce the setting of the operation part 11. In other embodiments, the valve 13 is connected to different operation parts 11 through different control holes 15, at this time, the movement of one operation part 11 can drive the valve 13 and the remaining operation parts 11 to move, which can also achieve the activity control and adjustment of the valve 13.

[0053] In addition to the above-mentioned fluid connector connecting end, the application also provides a fluid connector, which comprises a first connecting end 1 and a second connecting end 2, the first connecting end 1 can be specifically the connecting end of the fluid connector provided in any of the above embodiments, and the beneficial effects can be correspondingly referred to each of the above embodiments.

[0054] As shown in FIG. 5, the first connecting end 1 and the second connecting end 2 can be abutted and locked along the preset direction X. The preset direction X can be specifically the axial direction of the first connecting end 1. Among them, the second connecting end 2 comprises a valve seat and a valve movably connected to the valve seat, and the valve is moved to control the opening and closing of the communication passage on the valve seat. When the valve 13 in the first connecting end 1 and the valve in the second connecting end 2 are respectively opened to correspond to the communication passage 16, the communication passage 16 of the first connecting end 1 and the communication passage of the second connecting end 2 are connected.

[0055] Among them, in the state that the first connecting end 1 and the second connecting end 2 are abutted along the preset direction X, the operation part 11 can block the butt joint between the first connecting end 1 and the second connecting end 2, specifically, part of the structure of the operation part 11 protrudes from the connecting part 18 in the first connecting end 1 along the preset direction X, so as to be able to be sleeved outside the second connecting end 2, so that the operation part 11 can be blocked outside the butt joint, so as to expand the dust blocking range of the operation part 11.

[0056] Further, as shown in FIG. 1, at least part of the structure of the operation part 11 protrudes from the connecting part 18 along the preset direction X and constitutes a guide part 111. In the process that the first connecting end 1 and the second connecting end 2 approach along the preset direction X, the guide part 111 can guide the second connecting end 2 along the preset direction X, which can reduce the assembly difficulty of the first connecting end 1 and the second connecting end 2.

[0057] Further, the operation part 11 is connected with a locking structure 14. In the state that the first connecting end 1 and the second connecting end 2 abut along the preset direction X, the locking structure 14 can be locked by the movement of the operation part 11 to lock the first connecting end 1 and the second connecting end 2. The locking structure 14 can lock the position relationship of the first connecting end 1 and the second connecting end 2 after abutting along the preset direction X. The locking structure 14 is connected to the operation part 11, and the movement of the valve 13 and the assembly and disassembly of the first connecting end 1 and the second connecting end 2 can be realized by the operation part 11, which is convenient to operate.

[0058] In the embodiment, the locking structure 14 can be a clamping structure, and more specifically, the clamping structure includes a clamping hook arranged on the valve 13 of the first connecting end 1, and a clamping groove arranged on the valve of the second connecting end 2. When the first connecting end 1 and the second connecting end 2 abut along the preset direction X, the clamping hook extends into the clamping groove, and the clamping hook can be moved and clamped in the clamping groove by rotating the valve 13 of the first connecting end 1 through the operation part 11. In other embodiments, the locking structure 14 can also be a first magnetic element directly connected to the operation part 11, and the second connecting end 2 can also be provided with a second magnetic element. The first magnetic element and the second magnetic element can change the distance therebetween to connect and lock or separate the first connecting end 1 and the second connecting end 2.

[0059] In addition, the operation part 11 can first control the locking structure 14 to complete the locking action, and then drive the corresponding valve 13 to perform the opening action, or simultaneously perform the locking action and the opening action. The unlocking action and the closing action of the valve can also be performed in sequence or simultaneously.

[0060] It should be noted that the locking of the two connecting ends (the first connecting end 1 and the second connecting end 2) can specifically refer to the determination of the relative position of the valve seats of the two connecting ends to ensure the smooth flow of the fluid between the two connecting ends, and the position of the valve relative to the corresponding valve seat can be changed to open and close the corresponding communication channel. The disconnection of the two connecting ends can specifically refer to the separability of the two connecting ends, and the two connecting ends can be in a split state and move independently.

[0061] It should be noted that when an element is referred to as "fixed" to another element, it can be directly on the other element or there can be a middle element. When an element is referred to as "connected" to another element, it can be directly connected to the other element or there can be a middle element. In addition, in the description of the present application, unless otherwise specified, the meaning of "a plurality of", "a plurality of", "a plurality of" is two or more.
