[0044] In some embodiments, as shown in FIG. 1 and FIG. 2, the present embodiment provides a connecting end 100, mainly comprising a valve seat 10 and a valve core 20, wherein the valve seat 10 is provided with a plurality of communication channels 11, i.e. at least two communication channels 11, of course, it can also be provided with three, four or more communication channels 11. Different communication channels 11 are arranged side by side and separately, and generally do not communicate inside the connecting end 100. Among them, the valve core 20 is movably connected with the valve seat 10 and can be moved to a first position 201 and can be moved to a second position 202. In the first position 201, a plurality of communication channels 11 are closed, not all of them are required; while in the second position 202, a plurality of communication channels 11 are opened, not all of them are required. When the communication channel 11 is closed, the solid part of the valve core 20 blocks one end or the middle of the communication channel 11, so that the fluid cannot flow from one end to the other end of the communication channel 11; when the communication channel 11 is opened, it is no longer blocked, and at this time the fluid can flow from one end to the other end of the communication channel 11 and flow out. Among them, the valve core 20 does not block the communication channel 11, mainly in two forms, one is that the valve core 20 is away from the communication channel 11, and the other is that the through part on the valve core 20 is aligned with the communication channel 11, at this time the fluid can pass through the through part, so that the fluid can flow from one end to the other end of the communication channel 11.

[0045] By providing a plurality of communication channels 11, it can be applied to many scenes, such as used in a liquid cooling system: one can use the scene, the plurality of communication channels 11 of the connecting end 100 can be respectively connected to the plurality of water distribution ports of the water distributor, or the plurality of communication channels 11 can be respectively connected to the plurality of water collection ports of the water collector; one can use the scene, two communication channels 11 of the connecting end 100, one is connected to the water distribution port of the water distributor, and the other is connected to the water collection port of the water collector, and they are located in the same circulating system. Of course, in addition to the above application scenarios, it can also be applied to other scenarios. By simultaneously collecting a plurality of communication channels 11 on the connecting end 100, the volume can be greatly reduced, and the use cost can be reduced.

[0046] In some embodiments, a connecting end 100 is provided to cooperate with a counter end 200. It should be noted that two connecting ends 100 with substantially the same or completely same structure can be provided to be counter ends 200 of each other, of course, the counter end 200 here can also be completely different from the connecting end 100. As shown in FIG. 2, the counter end and the connecting end can be arranged reversely, and are not strictly arranged. When the structures are cooperatively arranged, one is a male head and the other is a female head.

[0047] As described above, the connecting end 100 includes a valve seat 10 and a valve core 20, wherein the valve seat 10 is provided with a plurality of communication channels 11 to respectively dock with each docking port 210 on the docking end 200, which is generally one-to-one correspondence, of course, it can also be one-to-many or many-to-one, the specific does not limit. Wherein the docking port 210 can make the port of the communication channel on the docking end 200 or the port of the communication hole. By docking, so that when the communication channel 11 is opened, the fluid in the communication channel 11 can flow into the docking port 210. At the docking, the shape does not require to be consistent, one can be circular, the other can be square, of course, it can also be coaxially arranged as shown in the drawing when docking.

[0048] Wherein the valve core 20 is movably arranged in the valve seat 10, such as sliding fit, rotating fit and the like to realize movable installation. Wherein the valve core 20 is provided with a combination part 21, the combination part 21 on the connecting end 100 is used to combine with the pushing part 12 on the docking end 200 and drive the valve core 20 to move, so as to drive the valve core 20 to move to the first position 201 and the second position 202. The combination mode of the combination part 21 and the pushing part 12 is such as magnetic attraction combination, insertion fit, meshing fit and the like, the specific structure of the combination part 21 can be correspondingly arranged according to the different combination modes, specifically, the combination part 21 is such as a groove structure. In order to facilitate the description, the groove structure is referred to as a pushing groove 211, which is inserted by the pushing part 12 to combine, so that when the pushing part 12 moves, the pushing part 12 and the wall of the pushing groove 211 abut to drive the valve core 20 to move.

[0049] Specifically, when the valve core 20 moves to the first position 201, it closes the plurality of communication channels 11, which can be all or part of the communication channels 11; and when the valve core 20 moves to the second position 202, it opens the plurality of communication channels 11, which can be all or part of the communication channels 11.

[0050] In some embodiments, when the connecting end 100 and the docking end 200 are docked, the pushing part 12 of the docking end 200 will combine with the combination part 21 on the valve core 20 to drive the valve core 20 of the connecting end 100 to move when the docking end 200 moves, such as when it is required to communicate the plurality of communication channels 11, the valve core 20 is pushed to move to the second position 202, at this time the communication channel 11 is communicated with the corresponding docking port 210, and when the valve core 20 is pushed to move to the first position 201, at this time the communication channel 11 is disconnected with the corresponding docking port 210. In the above connecting end 100, a plurality of communication channels 11 are provided on the valve seat 10 to simultaneously control the opening and closing of the plurality of communication channels 11, which can effectively reduce the cost compared with providing a plurality of connectors. In summary, the connecting end 100 can improve the problem of poor use effect of the connecting end 100 of the existing connector.

[0051] In some embodiments, the valve core 20 can be rotatably arranged on the valve seat 10, and each communication passage 11 can be arranged around the rotation axis 22 of the valve core 20. It should be noted that each communication passage 11 can be distributed on the same circumference or on different circumferences, for example, staggered distribution, so that the positions of each communication passage 11 are more compact.

[0052] The rotatable valve core 20 not only facilitates the pushing of the pushing part 12, but also combines the connection mode of the connection end 100 and the docking end 200, for example, the connection end 100 and the docking end 200 are connected in a rotating manner, such as screw connection, rotating clamping, etc. When the connection end 100 and the docking end 200 are connected, the valve core 20 is automatically pushed to rotate. At the initial stage of docking, the valve core 20 closes each communication passage 11, and when the docking is completed, the valve core 20 opens each communication passage 11, so that the connection end 100 and the docking end 200 are connected while the valve core 20 is driven to move, and each communication passage 11 is opened.

[0053] The communication passages 11 arranged around the rotation axis 22 of the valve core 20 can be uniformly or non-uniformly arranged, and both can fully utilize the excess space of the valve core 20. Generally, the side surface of the valve core 20 is sealed at the boundary, and the optimal way is to form a through hole in one half of the region to open the communication passage 11, and to form a solid in the other half of the region as a solid cover part to close the communication passage 11.

[0054] In some embodiments, the communication passages 11 are preferably uniformly arranged around the rotation axis 22 of the valve core 20. When each solid cover part on the valve core 20 is rotated between two communication passages 11, each communication passage 11 is opened, and when the solid cover part is rotated to align with the corresponding communication passage 11, the corresponding communication passage 11 is closed.

[0055] In some embodiments, the central angle value a corresponding to adjacent communication passages 11 is twice the preset rotation angle value b of the valve core 20, and the valve core 20 can be located at the second position 202 after rotating the preset rotation angle, so as to ensure that the solid cover part of the valve core 20 can be rotated to face the communication passage 11. Of course, the preset rotation angle value can be less than or greater than half of the central angle value corresponding to adjacent communication passages 11. For example, the central angle value a corresponding to adjacent communication passages 11 is 120 degrees, and three communication passages 11 are uniformly arranged, so that the preset rotation angle value b can be 60 degrees. For example, the central angle value a corresponding to adjacent communication passages 11 is 90 degrees, and four communication passages 11 are uniformly arranged, so that the preset rotation angle value b can be 45 degrees.

[0056] In some embodiments, as described above, the valve seat 10 can be provided with three or more communication channels 11, which can accommodate more passages. In order to make the overall structure of the connection end 100 more compact, while accommodating more scenarios, it is preferred here that the valve seat 10 is provided with only two communication channels 11, which are centrally symmetrically arranged with respect to the rotation axis 22 of the valve core 20. At this time, the preset rotation angle value can be about 90 degrees, so that the valve core 20 can enter the second position 202 after rotating about 90 degrees in the first position 201, and can enter the first position 201 after reversing about 90 degrees in the second position 202. By arranging only two communication channels, compared with three communication channels, it can be arranged more compactly, while avoiding interference, and can fully utilize the space. At this time, it corresponds to the preferred rotation clamping between the connection end 100 and the counter end 200, so that when the connection end 100 and the counter end 200 are inserted into each other to enter the initial stage of counter, at this time the connection end 100 and the counter end 200 are rotated by 90 degrees with respect to each other, the rotation clamping is completed, and at this time the valve core 20 enters the second position 202.

[0057] In some embodiments, the valve core 20 can be in the form of a disc, and of course can also be in the form of a fan, or other shapes, and the specific shape can be set according to the needs. Generally, a sealing device is provided on the side of the valve core 20 in contact with the valve seat 10, as shown in FIG. 3, and a sealing device is provided on both axial sides of the valve core 20 to seal and fit with the valve body 14 and the valve cover 15, respectively. The sealing device can be a sealing gasket or a sealing ring 50. In order to better achieve sealing, the sealing ring here includes a circular ring portion coaxially arranged with the rotation axis 22 and a partition portion arranged on the circular ring portion, and the partition portion has a shape equal to the cross-sectional shape of the communication channel 11, such as a circular shape. And because multiple communication channels are provided, multiple partition portions are correspondingly provided, and are arranged one by one with the communication channels, such as when the valve core 20 rotates to the second position 202, at this time the communication hole 23, the communication channel 11 and the partitioned area are coaxially arranged, and the boundary of the partitioned area is larger than the boundary of the communication hole 23, so as to avoid protruding inside and affecting the flow of fluid.

[0058] In some embodiments, the valve seat 10 of the connection end 100 is used to rotate with the counter end 200, specifically, to rotate with the valve seat 10 of the counter end 200. The rotation connection can be a threaded connection, a rotation clamping, etc. When the connection end 100 and the counter end 200 are rotated to connect, the pushing part 12 in the counter end 200 can be combined with the combination part 21, and correspondingly drive the pushing part 12 to move to the second position, and when disassembled, correspondingly drive the pushing part 12 to move to the first position.

[0059] In some embodiments, as described above, the connecting end 100 can be achieved with the rotating clamping with the mating end 200, and the two matching structures of the rotating clamping, namely the rotating clamping convex and the rotating clamping slot 13, are used for convenient distinction. In the separated state, after the insertion along the rotation axis 22, the rotating clamping convex is mainly moved from one end of the rotating clamping slot 13 to be aligned with the clamping slot, and then the rotation axis 22 is rotated. At this time, the clamping convex is turned into the clamping slot, and the slot direction of the clamping slot is perpendicular to the direction of the rotation axis 22. After the clamping convex is turned into the clamping slot, the side of the clamping convex in the direction of the rotation axis 22 is abutted with the slot wall of the clamping slot to achieve axial limiting.

[0060] Specifically, the valve seat 10 of the connecting end 100 can be provided with the rotating clamping slot 13 for rotating clamping with the pushing part 12 of the mating end 200, and the combination part 21 is provided with the pushing slot 211 matched with the pushing part 12 of the mating end 200. When the pushing part 12 is axially moved to be axially aligned with the rotating clamping slot 13, the front end of the pushing part 12 is inserted into the pushing slot 211. When the rotating clamping convex at the front end of the pushing part 12 is rotated and turned into the rotating clamping slot 13, the pushing part 12 is abutted with the slot wall of the pushing slot 211, so as to drive the valve core 20 provided with the pushing slot 211 to rotate.

[0061] In some embodiments, in order to facilitate the installation of the valve core 20, the valve seat 10 preferably includes the valve body 14 and the valve cover 15. One end of the valve body 14 is provided with the connecting head 30 for connecting the external channel, and the other end is provided with the valve cover 15. The valve cover 15 is fixedly connected with the valve body 14 by welding, screw connection or the like. The valve core 20 is arranged between the valve cover 15 and the valve body 14. In assembly, the valve cover 15 and the valve body 14 are separated, and then the valve core 20 is clamped between the valve cover 15 and the valve body 14, and the valve cover 15 and the valve body 14 are fixedly connected. At this time, the valve core 20 can rotate in the valve cover 15 and the valve body 14.

[0062] Further, the valve core 20 can be provided with a plurality of communication holes 23 corresponding to the respective communication channels 11, and the communication channels 11 are at least partially arranged on the valve body 14. There are at least two schemes. In one scheme, only the communication channels 11 are arranged on the valve body 14. At this time, the valve core 20 is generally blocked at one end of the communication channel 11 close to the valve cover 15, and the communication hole 23 on the valve core 20 of the connecting end 100 is directly connected with the mating port 210 on the mating end 200, such as directly connected with the communication hole 23 on the valve core 20 of the mating end 200. In another scheme, a section of the communication channel 11 is arranged on the valve body 14 and the valve cover 15 respectively. At this time, the valve core 20 is blocked between the two sections of the communication channel 11.

[0063] The communication passage 11 is opened when the valve core 20 is rotated to align the communication hole 23 with the communication passage 11, and is closed when the valve core 20 is rotated to misalign the communication hole 23 with the communication passage 11, so that the solid part of the valve core 20 blocks the communication passage 11.

[0064] The communication passage 11 and the communication hole 23 preferably have equal cross sections so that the hole walls are located on the same extension plane when aligned. For example, the communication passage 11 and the communication hole 23 are both circular and have equal diameters. For example, they are both rectangular and have equal sizes and shapes, and the edges are aligned when aligned. Of course, they can also have different shapes.

[0065] In some embodiments, the valve seat 10 is provided with a locking pin 40 for preventing the valve core 20 from moving relative to the valve seat 10. The locking pin 40 is axially movably connected to the valve seat 10 and generally has an operating key 41 exposed to the outside for easy operation. The valve core 20 is provided with a locking hole 24, so that when the valve core 20 is rotated to the first position 201, the locking pin 40 can move into the locking hole 24. To facilitate operation, a locking mechanism is preferably provided here, so that when the locking pin 40 moves out of the locking position, the locking pin 40 can be kept in the current position without driving the locking pin 40 forward by the elastic device, and when the locking mechanism is unlocked, the locking pin 40 can be extended forward under the action of the elastic device to enter the locking hole 24 to enter the locking position.

[0066] In some embodiments, the above-mentioned locking hole 24 and the connecting part 21 are preferably arranged radially outward of the area where the communication hole 23 is located, so as to leave a central area for better arrangement of the communication hole 23 and the solid covering part.

[0067] In some embodiments, the valve cover 15 preferably has a pushing part 12 and a rotating clamping groove 13 on the side away from the valve body 14. There are generally two pushing parts 12 arranged in a central symmetric manner to push the valve core 20 inside the docking end 200 and realize rotating clamping with the rotating clamping groove 13 on the valve seat 10 of the docking end 200.
