[0037] 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 in 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.

[0038] The core of the utility model is to provide a connecting end of a fluid connector and a fluid connector, which can more conveniently perform the opening and closing operations of the communication channel.

[0039] For a specific embodiment of the connection end of the fluid connector provided by the present invention, please refer to Figures 1 to 5 The connecting end includes a connecting portion 18 and an operating portion 11.

[0040] like Figure 1 and Figure 2 As shown, the connection 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, and the communication channel 16 is opened or closed by the movement of the valve 13 on the valve seat 12 (for example, rotation, or movement in a set direction), thereby realizing the opening and closing of the communication channel 16 on the connection part 18.

[0041] The valve 13 is rotatably connected to the valve seat 12. Specifically, the valve 13 is arranged on one side or the middle of the communication channel 16 in a preset direction about its rotation axis. The valve 13 is rotatably 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 may also extend along the preset direction and be a linear channel, or may be a curved channel in other embodiments.

[0042] More specifically, if Figure 5As shown, the rotation axis of the valve 13 is parallel to or coincides with the axis line O of the connecting portion 18, wherein, unless otherwise specified, the axis line O of the connecting portion 18 is the center line along the direction in which it connects to the other connecting end, and the valve 13 and the connecting channel 16 in the connecting portion 18 are also usually arranged along this direction, which can be a preset direction, and the axial, circumferential and radial directions are also based on the axis line O.

[0043] In other embodiments, the valve 13 may also be flipped around an axis that is perpendicular to the preset direction or at other angles.

[0044] like Figure 1 and Figure 5 As shown, the operating part 11 is movably connected to the outer side of the valve seat 12, and is used to receive external force to drive the valve 13 to move relative to the valve seat 12. The valve 13 is connected to the operating part 11 through the control hole 15 on the valve seat 12. Specifically, the valve 13 can be directly connected to the operating part 11 through the control hole 15, or connected to the operating part 11 through a transmission mechanism. When the operating part 11 moves, the valve 13 can be driven to move to control the opening and closing of the connecting channel 16 on the connecting part 18. It can be understood that the valve 13 can be directly connected to the operating part 11 through the control hole 15, which can refer to a part of the structure of the valve 13 passing through the control hole 15 and connected to the operating part 11.

[0045] In the fluid connector of this embodiment, the operating part 11 is externally disposed on the valve seat 12. When the connecting channel 16 needs to be opened and closed, the user can drive the operating part 11 to drive the valve 13 to move, and there is no need to directly drive the valve seat 12, thereby making it more convenient to open and close the connecting channel 31.

[0046] When the operating part 11 is at any position within its movable range, the operating part 11 always covers the control hole 15, and optionally, the operating part 11 is sealed and matched with the control hole 15. The movable range of the operating part 11 refers to the set of various positions to which the operating part 11 can move relative to the connecting part 18 based on structural restrictions or other settings.

[0047] The fluid connector in this embodiment can control the connection and disconnection of the connecting channel 16 by driving the operating part 11. At the same time, since the operating part 11 can block the control hole 15, it can reduce the entry of foreign objects (including dust and other foreign dirt) into the control hole 15, thereby reducing the direct contact or impact of foreign objects on the valve 13 or entering the inside of the connecting end through the control hole 15, thereby reducing the influence of the control hole 15 on the normal use of the fluid connector.

[0048] Furthermore, if Figure 1As shown, the operating portion 11 includes a sleeve sleeved outside the valve seat 12, which can ensure the shielding effect of the control hole 15. Of course, in other embodiments, the operating portion 11 can also be a shielding sheet, which shields the control hole 15 and part of the area near it, and when the shielding sheet moves to any allowed position, the control hole 15 remains shielded.

[0049] In addition, if Figure 1 As shown, the operating portion 11 is rotatably connected to the valve seat 12, and specifically can be rotated around the axis O of the connecting portion 18. At this time, the operating portion 11 rotates relative to the valve seat 12 to drive the valve 13 to move, which is convenient for operation. Of course, in other embodiments, the operating portion 11 can also translate along the axial direction relative to the valve seat 12 to drive the valve 13 to move.

[0050] In addition, at least part of the structure of the sleeve protrudes from the valve seat 12, so that when the connecting portion 18 is connected to the other connecting end in the fluid connector, the protruding part of the sleeve can be sleeved on the other connecting end, so that the sleeve can cover the connecting portion between the other connecting end and the connecting portion 18. In addition, the protruding part of the sleeve can also be used as a guide portion 111, which has a good fit with the outer surface of the other connecting end in the fluid connector, for example, it can be sealed, or the gap is small, so that when the other connecting end in the fluid connector and the connecting portion are close to each other along the preset direction X, the guide portion 111 can guide the other connecting end in the fluid connector along the preset direction X.

[0051] Furthermore, if Figure 2 As shown, the control hole 15 may 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 allow the operating portion 11 to have enough space to connect the valve 13. Specifically, the control hole 15 extends along the circumferential direction, and in other embodiments, the control hole 15 may also extend along the axial direction.

[0052] In addition, if Figure 2 As shown, the valve 13 is fixedly connected to the connecting rod 17, which can be screwed or bonded after the valve 13 is installed on the valve seat 12. The connecting rod 17 is fixedly connected to the operating part 11, which can be connected to the operating part 11 through the control hole 15, and can be bonded or screwed after the operating part 11 is installed on the connecting part 18. This transmission method has a simple structure, and transmission between the operating part 11 and the valve 13 can be achieved only through the connecting rod 17, which is convenient for processing. At this time, the rotation of the operating part 11 drives the valve 13 to rotate. Of course, in other embodiments, the transmission between the operating part 11 and the valve 13 can also be achieved through other transmission structures, such as a screw nut assembly, a gear transmission assembly, and specifically, the operating part 11 can be a knob, which is connected to the valve 13 through a gear transmission mechanism. The rotation of the knob drives the valve 13 to rotate or translate.

[0053] Of course, in other embodiments, there may be a time or position where the control hole 15 is exposed within the movable range of the operating part 11. For example, the connecting rod 17 in the above embodiment may directly extend outside the valve seat 12, and the extended portion serves as the operating part 11.

[0054] In addition, the number of the control holes 15 can be at least two, such as Figure 2 and Figure 3 As shown, two control holes 15 are evenly arranged in the circumferential direction. Of course, in other embodiments, one, three or other numbers of control holes 15 may be arranged. The operating part 11 is connected to the valve 13 through each control hole 15. The operating part 11 can cover each control hole 15 at the same time, which can reduce the number of operating parts 11. In other embodiments, the valve 13 is connected to different operating parts 11 through different control holes 15. In this case, the movement of one operating part 11 can drive the valve 13 and the other operating parts 11 to move, and the activity control and adjustment of the valve 13 can also be achieved.

[0055] In addition to the connection end of the above-mentioned fluid connector, the utility model also provides a fluid connector, which includes a first connection end 1 and a second connection end 2. The first connection end 1 can specifically be the connection end of the fluid connector provided in any of the above embodiments, and the beneficial effects can be referred to the above embodiments accordingly.

[0056] like Figure 5 As shown, the first connection end 1 and the second connection end 2 can be abutted and locked along a preset direction X. The preset direction X can specifically be the axial direction of the first connection end 1. The second connection end 2 includes a valve seat and a valve movably connected to the valve seat, and the opening and closing of the communication channel on the valve seat are controlled by the movement of the valve. When the valve 13 in the first connection end 1 and the valve in the second connection end 2 open the corresponding communication channel 16 respectively, the communication channel 16 of the first connection end 1 and the communication channel of the second connection end 2 are connected.

[0057] In which, when the first connection end 1 and the second connection end 2 are in a state of being against each other along a preset direction X, the operating portion 11 can cover the docking point between the first connection end 1 and the second connection end 2. Specifically, part of the structure of the operating portion 11 protrudes from the connecting portion 18 in the first connection end 1 along the preset direction X so that it can be sleeved on the outside of the second connection end 2, so that the operating portion 11 can be shielded on the outside of the docking point to expand the shielding and dustproof range of the operating portion 11.

[0058] Furthermore, if Figure 1As shown, at least part of the structure of the operating portion 11 is protruded from the connecting portion 18 along the preset direction X, and constitutes a guide portion 111. When the first connecting end 1 and the second connecting end 2 are brought close to each other along the preset direction X, the guide portion 111 can guide the second connecting end 2 along the preset direction X, thereby reducing the difficulty of assembling the first connecting end 1 and the second connecting end 2.

[0059] Furthermore, the operating part 11 is connected with a locking structure 14. When the first connection end 1 and the second connection end 2 are in abutment with each other along a preset direction X, the locking structure 14 can be driven to lock the first connection end 1 and the second connection end 2 by the movement of the operating part 11. The locking structure 14 can lock the positional relationship between the first connection end 1 and the second connection end 2 after they are in abutment with each other in the preset direction X. By connecting the locking structure 14 to the operating part 11, the movement of the valve 13 and the assembly and disassembly of the first connection end 1 and the second connection end 2 can be realized through the operating part 11, which is convenient to operate.

[0060] Among them, the locking structure 14 can be a snap-on structure, more specifically, the snap-on structure includes a hook set on the valve 13 of the first connection end 1, and a slot is set on the valve of the second connection end 2. When the first connection end 1 and the second connection end 2 are against each other along the preset direction X, the hook extends into the slot, and the valve 13 of the first connection end 1 is driven to rotate by the rotation of the operating part 11, which can drive the hook to move and snap into the slot. In other embodiments, the locking structure 14 can also be a first magnetic part directly connected to the operating part 11, and the second connection end 2 can also be provided with a second magnetic part accordingly, and the distance between the first magnetic part and the second magnetic part is changed to make the first connection end 1 and the second connection end 2 connected, locked or separated.

[0061] In addition, the operating part 11 can first control the locking structure 14 to complete the locking action, and then drive the corresponding valve 13 to open the action, or perform them simultaneously; the unlocking action and the valve closing action can also be performed sequentially or simultaneously.

[0062] It should be noted that the two connection ends (the first connection end 1 and the second connection end 2) are locked, which specifically refers to that the relative positions of the valve seats of the two connection ends are determined to ensure the smooth flow of the fluid between the two connection ends, and the position of the valve relative to the corresponding valve seat can be changed so that the valve opens and closes the corresponding connecting channel; the two connection ends are disconnected, which specifically refers to that the two connection ends can be separated, and the two connection ends can be in a split state and move independently.

[0063] It should be noted that when an element is referred to as "fixed" to another element, it may be directly on the other element or there may be an element in the middle. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an element in the middle at the same time. In addition, in the description of the present utility model, unless otherwise specified, "multiple", "multiple roots", and "multiple groups" mean two or more.

[0064] The terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0065] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0066] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
