DETAILED DESCRIPTION

[0027] An embodiment of the present application discloses a fluid connector, which can solve the problem that the connection end of a detachable fluid connector is inconvenient to assemble and disassemble.

[0028] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] Please refer to Figures 1-4, Figure 1 is a schematic diagram of the three-dimensional structure of the connecting end of the fluid connector provided in an embodiment of the present application; Figure 2 is a schematic diagram of the cross-sectional structure of the fluid connector provided in an embodiment of the present application; Figure 3 is a schematic diagram of the exploded structure of the connecting end of the fluid connector provided in an embodiment of the present application; Figure 4 is a schematic diagram of the structure of the integrated boss structure provided in an embodiment of the present application.

[0030] For example, Chinese patent publication number CN117249325A discloses a fluid connector structure comprising two mating connecting ends, each of which includes a valve seat and a valve core. The valve core is rotatably mounted within the valve seat, the valve core having a communication hole, and the valve seat having a communication channel. One end of the valve seat is used to connect to the other connecting end and has a push portion inserted into the valve core of the other connecting end. The other end of the valve seat is used to connect to a pipeline, and the communication channel connects the other connecting end and the pipeline. When the valve core rotates until the communication hole and the communication channel are aligned, the connection state is reached; when the valve core rotates until the communication hole and the communication channel are completely offset, the connection state is reached.

[0031] During use, when the two ends of a fluid connector rotate relative to each other, one end will always rotate relative to the other, pushing the valve core to open. Operation is typically done manually, which can be difficult due to poor manual force. Long-term operation significantly increases fatigue and reduces work efficiency. In particular, the valve core's high rotational resistance makes it difficult to reduce torque.

[0032] In some embodiments, this embodiment provides a fluid connector. Specifically, the fluid connector includes two mating connection ends 1. The structures of the two connection ends 1 can be completely the same, or they can have different adaptabilities.

[0033] In some embodiments, the connecting end 1 mainly includes a valve seat 10 and a valve core 20, wherein the valve core 20 is movable relative to the valve seat 10 and can move between closing the connecting channel 10-1 of the valve seat 10 and opening the connecting channel 10-1. Generally speaking, the valve core 20 can be rotated or translated to enter and exit the closed position and the open position, and there is no requirement for the movable form of the valve core 20. In the closed position, the physical part of the valve core 20 is blocked at one end or the middle of the connecting channel 10-1, so that the fluid cannot flow from one end of the connecting channel 10-1 to the other end; in the open position, that is, the connecting channel 10-1 is opened and no longer blocked, at which time the fluid can flow from one end of the connecting channel 10-1 to the other end and flow out.

[0034] The valve seat 10 on at least one connecting end 1 has a connecting portion 10-2 on one side for realizing rotational cooperation with the other connecting end 1. The other connecting end 1 may be provided with a valve seat 10 and a valve core 20, or may not be provided with a valve seat 10 and a valve core 20. When the other connecting end 1 is provided with a valve seat 10, the aforementioned connecting portion 10-2 is used for rotational connection with the valve seat 10 of the other connecting end 1, such as rotational clamping, threaded connection, etc. Specifically, if one connecting end 1 is the first connecting end and the other connecting end 1 is the second connecting end, at least the first connecting end 1 has the above-mentioned valve seat 10 and valve core 20, which are respectively referred to as the first valve seat and the first valve core for the sake of convenience. The second connecting end may not be provided with a valve seat 10 and a valve core 20, or may be provided with a valve seat 10 and a valve core 20, such as the second valve seat and the second valve core, respectively. The first valve seat 10 has a connecting portion 10 - 2 to directly match the second connecting end 1 . When the second connecting end 1 has the second valve seat 10 , the connecting portion 10 - 2 of the first valve seat 10 and the second valve seat 10 may be rotatably connected.

[0035] A locking pin 2 is provided on the valve seat 10 for preventing the valve seat 10 from moving relative to the valve core 20 and / or rotating relative to the other connection end 1. As shown in the accompanying drawings, the locking pin 2 is used to prevent the valve core 20 and the valve seat 10 in the same connection end 1 from rotating relative to each other, thereby preventing the valve core 20 from moving to the open position and / or the closed position. As described below, the valve core 20 is relatively fixed to the valve seat 10 of the other connection end 1, so at this time, it can prevent the valve seat 10 from rotating relative to the valve seat 10 on the other connection end 1. Of course, the locking pin 2 can also be used directly to prevent the valve seats 10 of the two connection ends 1 from rotating relative to each other, such as preventing the first valve seat and the second valve seat from rotating relative to each other as described above. In this case, the locking pin 2 is installed on the first valve seat, and the pin portion can be optionally inserted into the pin hole on the second valve seat, or retracted from the pin hole. The locking pin 2 mainly plays a protective role, preventing the two valve seats 10 from rotating relative to each other at will, and / or the valve core 20 from opening at will.

[0036] The other side of the valve seat 10 is provided with a connecting head 10-3 for connecting a pipe and a mounting portion 10-4 for mounting the locking pin 2, that is, on the side away from the connecting portion 10-2, it is protruded in the direction away from the connecting portion 10-2. The parallel direction of the connecting portion 10-2 and the connecting head 10-3 is the extension direction of the rotation axis, and is also the extension direction of the connecting channel 10-1. The connecting head 10-3 is used to connect a pipe, and is generally provided with a corresponding clamping portion, a socket, a threaded portion, etc. As shown in the figure, the connecting head 10-3 is provided with an internal threaded hole to facilitate the insertion of the pipe or the intermediate connector connecting the pipe, and threaded connection. Since the locking pin 2 requires a certain amount of movable stroke, it requires axial movable space, and the protruding mounting portion 10-4 can provide this space.

[0037] The mounting portion 10-4 and the connecting head 10-3 are respectively located on either side of the radial direction of the rotation axis of the valve seat 10 and are combined into a long strip structure to serve as the rotation operation portion of the valve seat 10. It should be noted that the mounting portion 10-4 and the connecting head 10-3 are radially arranged side by side to form a long strip structure. The two can be connected or separated. It only needs to be elongated as a whole, that is, to achieve a longitudinal span in the radial direction, so that both the mounting portion 10-4 and the connecting head 10-3 can form an operating surface perpendicular to the circumferential direction, thereby facilitating the direct application of torque.

[0038] When torque needs to be applied to the valve seat 10, one of the mounting portion 10-4 and the connecting head 10-3 can be used as a support point, and the other as a torque application point, to form a set of torques to facilitate driving the valve seat 10 to rotate. Due to the travel requirements of the locking pin 2 and the structural requirements of the support seat 10-6, the locking pin 2 generally requires a relatively large axial distance, and the connecting head 10-3 also requires a relatively large axial distance, so their protrusion is generally sufficient for finger operation. Specifically, this protrusion distance can be made no less than 6 mm to ensure space for finger operation. It should be noted that the mounting portion 10-4 and the connecting head 10-3 are respectively located on both sides of the radial direction of the rotation axis of the valve seat 10, and do not need to be completely distributed on both sides. They should be mostly distributed on both sides. That is, from an overall perspective, at least one feasible embodiment is that the center line of the mounting portion 10-4 and the center line of the connecting head 10-3 can be respectively located on both sides of the radial direction of the rotation axis of the valve seat 10.

[0039] In some embodiments, when using the above-mentioned fluid connector, the two connecting ends 1 are operated to cooperate, even if the connecting portion 10-2 on the valve seat 10 of one of the connecting ends 1 extends into the other connecting end 1, when the other connecting end 1 has a valve seat 10, it can specifically extend into the valve seat 10 of the other connecting end 1. Then, the fingers act on the long strip structure composed of the mounting portion 10-4 and the connecting head 10-3 to apply torque. Because it is a long strip structure, it is convenient to apply torque, thereby making the overall operation simple and convenient. In the above-mentioned fluid connector, by protruding the mounting portion 10-4 and the connecting head 10-3 and forming a long strip that is easy to operate, it is convenient to apply torque here, and it is convenient for the fingers to apply torque without having to set up a separate operating portion. Therefore, it is not only easy to operate, but also small and simple in size. In summary, the fluid connector can effectively solve the problem of inconvenient operation of the fluid connector.

[0040] In some embodiments, the mounting portion 10-4 and the connecting head 10-3 can be connected to form an integrated long strip structure to facilitate the application of torque. Specifically, the mounting portion 10-4 and the connecting head 10-3 can be connected to form an operating plane 10-12 parallel to the rotation axis of the valve seat 10, so that a torque force can be applied to one end of the operating plane 10-12. Generally, the above-mentioned operating plane 10-12 is formed on both sides of the rotation axis of the valve seat 10, so that during operation, some fingers abut against the operating plane 10-12 on one side, while the other fingers abut against the operating plane 10-12 on the other side.

[0041] In some embodiments, the connecting head 10-3 and the mounting portion 10-4 can be both columnar and separately arranged, such as both being cylindrical structures, or of course a square column structure. The connecting head 10-3 is coaxially arranged with the communicating channel 10-1 to form a linear channel. The mounting portion 10-4 is coaxially arranged with the pin shaft portion of the locking pin 2 to ensure that the mounting portion 10-4 and the connecting head 10-3 are as far apart as possible and to avoid excessive diameter. Specifically, during operation, on one side, some fingers abut against the connecting head 10-3, and on the other side, another part of the fingers abut against the mounting portion 10-4 to form torque drive, and one part of the fingers is the thumb, such as the thumb abuts against the connecting head 10-3, while the index finger and middle finger abut against the mounting portion 10-4.

[0042] In some embodiments, the mounting portion 10-4 and the connecting head 10-3 can be combined into an integrated boss structure 10-5, that is, the integrated boss structure 10-5 is a long strip structure.

[0043] In some embodiments, the axial cross-sectional outer contour of the integrated boss structure 10-5 can include a first arc segment 10-51, a first straight segment 10-52, a second arc segment 10-53, and a second straight segment 10-54, which are sequentially connected in an annular shape. The first arc segment is coaxial with the connecting channel 10-1, and the second arc segment is coaxial with the pin shaft of the locking pin 2. The arc segments at both ends better fit the fingers, making operation more comfortable and convenient. Of course, the first and second arc segments can also be straight segments.

[0044] In some embodiments, the first straight line segment and the second straight line segment can be tangent to the first arc segment and the second arc segment, respectively, to improve the overall transition and ensure better strength. Generally speaking, the diameter of the first arc segment is not greater than the distance between the axes of the first arc segment and the second arc segment.

[0045] Of course, they can also be non-tangent, so that the distance between the first straight segment and the second straight segment can be shorter than the diameter of the first arc segment and / or the diameter of the second arc segment, so that a contraction is formed at the first straight segment and the second straight segment, such as forming a barbell structure. In this case, the central angles of the first arc segment and the second arc segment are both greater than 180 degrees.

[0046] In some embodiments, the diameter of the first arc segment can be made larger than the diameter of the second arc segment to avoid using an overly large columnar structure at the mounting portion 10-4, which would cause cost waste. Moreover, since the diameter of the first arc segment is larger than the diameter of the second arc segment, the cross-section of the above-mentioned integrated boss structure 10-5 is teardrop-shaped, which is more convenient to operate.

[0047] In some embodiments, on the integrated boss structure 10-5, in order to facilitate the installation of the locking pin 2, the locking pin 2 or a partial structure of the locking pin 2 can be installed from the integrated boss structure 10-5. As shown in the figure, the supporting portion on the locking pin 2, such as the elastic supporting portion and other active portions, can be installed into the valve seat 10 from the opening on the integrated boss structure 10-5. Specifically, the mounting portion 10-4 can be provided with a support seat 10-6 for mounting the locking pin 2, and the support seat 10-6 can be inserted into the mounting hole of the mounting portion 10-4 away from the other connecting end 1. Of course, the locking pin 2 or a partial structure thereof can also be installed from the side of the mounting hole away from the valve core 20, and the plug and the mounting hole can be threaded, snap-fitted or interference fit.

[0048] In some embodiments, based on some of the above embodiments, the valve core 20 can be rotatably installed on the valve seat 10 and the rotation axis can be consistent with the rotation axis of the valve seat 10, so that when the valve seats 10 at the two connecting ends 1 are rotated relative to each other, the valve core 20 rotates accordingly to simultaneously place the valve core 20 in the open position.

[0049] In some embodiments, the connecting portion 10-2 can be a clamping portion, and the valve seat 10 is provided with a clamping groove 10-11 for rotating and clamping with the clamping portion on the other connecting end 1 to achieve axial locking after rotation.

[0050] In some embodiments, the valve core 20 can have a bayonet 20-2 to be able to cooperate with the head of the clamping portion on the other connecting end 1 to rotate with the valve seat 10 on the other connecting end 1, so that the clamping portion not only serves as a clamping structure, but also as a pushing portion.

[0051] In some embodiments, when two such connecting ends 1 are mated and connected, for ease of description, the two connecting ends 1 are respectively referred to as the first connecting end and the second connecting end. The first is added to the corresponding structure belonging to the first connecting end 1, such as the first valve seat, the first valve core, the first clamping portion, etc., and the second is added to the corresponding structure belonging to the second connecting end 1, such as the second valve seat, the second valve core, the second clamping portion, etc. It should be noted that the first connecting end and the second connecting end can have exactly the same structure, or they can have some differences, such as being a male end and a female end, respectively.

[0052] When operating from the disconnected state to the connected state, the first and second connecting ends are first inserted into each other, that is, the first engaging portion is inserted into the second valve seat engaging groove, and the second engaging portion is inserted into the first valve seat engaging groove. The end of the first engaging portion extends into the engaging groove 20-2 of the second valve core, and the end of the second engaging portion extends into the engaging groove 20-2 of the first valve core to achieve torque transmission. Because the first engaging portion is inserted into the second valve seat engaging groove and the second engaging portion is inserted into the first valve seat engaging groove, the first and second valve seats are constrained to rotate relative to each other about the axis of the valve core 20. Specifically, this can be a rotational engagement relationship, so that after rotation, they are axially locked.

[0053] Then the first valve seat and the second valve seat are rotated relative to each other. At this time, relative to the mounting base, at least one of the first valve seat and the second valve seat needs to be rotated relative to the mounting base. For example, to operate the first valve body to rotate, the fingers of one hand act on the above-mentioned long strip structure, and the second valve body can be fixed by other structures, or the fingers of the other hand can act on the long strip structure.

[0054] During rotation, the first valve core and the second valve seat are relatively fixed and both rotate relative to the first valve seat, while the second valve core and the first valve seat are relatively fixed and both rotate relative to the second valve seat. When the second valve seat 10 is rotated into place relative to the first valve seat, the first valve core and the second valve core are both in the open position.

[0055] In some embodiments, based on some of the above embodiments, in order to facilitate the installation of the valve core 20, the above-mentioned valve seat 10 can include a valve body 10-7 and a valve cover 10-8, and the valve body 10-7 has a connecting head at one end and a valve cover 10-8 at the other end, and a valve core 20 is arranged between the valve cover 10-8 and the valve body 10-7; and the above-mentioned valve body 10-7 is provided with a connecting channel 10-1, and the valve cover 10-8 is provided with a docking channel 10-9, and the docking channel 10-9 and the connecting channel 10-1 are coaxially arranged and have equal diameters. When the valve core 20 rotates to open the connecting channel 10-1, the connecting hole on the valve core 20 is connected between the connecting channel 10-1 and the docking channel 10-9, and they are all coaxially arranged, and preferably, at this time, the diameters of the connecting hole, the connecting channel 10-1 and the docking channel 10-9 on the valve are equal and are all coaxially arranged.

[0056] On one side of the valve body 10-7 away from the valve cover 10-8, a clamping portion and a clamping groove 10-11 are provided, that is, the first valve cover is provided with a first clamping groove, and the second valve cover is provided with a second clamping groove, so that the clamping portion can be rotatably clamped with the clamping groove of the other connecting end 1. Generally speaking, the clamping groove has a perforated portion and a groove portion connected to the perforated portion and narrower than the perforated portion. The clamping portion includes a handle and an enlarged head provided at one end of the handle in the axial direction. The enlarged head can pass through the above-mentioned perforated portion until the handle enters the perforated portion, wherein the enlarged head protrudes from the handle, and then the clamping portion rotates with the valve seat 10. At this time, the handle enters the groove, and the enlarged head cannot pass over the groove due to its protruding handle, thereby achieving axial clamping.

[0057] In some embodiments, the valve cover 10-8 can include a disc portion 10-10 and a connecting head 10-3 and a mounting portion 10-4 protruding from the side of the disc portion 10-10 away from the valve core 20, with the protrusion being an integrated boss structure 10-5. Because of the existence of the integrated boss structure 10-5, the axial thickness of the disc portion 10-10 is no longer subject to the axial dimension requirements of the locking pin 2 and the axial dimension requirements of the connecting head 10-3.

[0058] In some embodiments, the valve cover 10-8 can be a cap-shaped structure, and the inner cap edge of the valve cover 10-8 is mounted on the disc portion 10-10 and fixedly connected thereto, such as by threading or clamping. Since the valve cover 10-8 and the valve body 10-7 need to be precisely positioned in the circumferential direction, it is preferred that the connection be fixed directly by axially extending screws or bolts.

[0059] In some embodiments, the valve body 10-7 can be an integrally formed structure, that is, the above-mentioned disc portion 10-10 and the integral boss structure 10-5 are integrally formed, that is, the disc portion 10-10, the mounting portion 10-4 and the connecting head 10-3 are integrally formed and connected.

[0060] In some embodiments, in order to facilitate external connection, the connecting head 10 - 3 can be connected to an adapter to connect to the corresponding pipeline through the adapter.

[0061] Based on the fluid connector provided in the above embodiments, the present application further provides a liquid cooling device, which includes any one of the fluid connectors in the above embodiments. Since the liquid cooling device uses the fluid connector in the above embodiments, the beneficial effects of the liquid cooling device can be referred to the above embodiments.

[0062] 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.

[0063] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
