[0049] 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.

[0051] In some embodiments, as shown in the attached Figure 1 , 2 As shown, this embodiment provides a connection end 100, which mainly includes a valve seat 10 and a valve core 20, wherein the valve seat 10 is provided with a plurality of communication channels 11, that is, at least two communication channels 11 are provided, and of course, three, four or more communication channels 11 may also be provided. Different communication channels 11 are arranged in parallel and separately, and are generally not connected inside the connection end 100. The valve core 20 is movably connected to the valve seat 10 and can move to a first position 201 and a second position 202. In the first position 201, a plurality of communication channels 11 are closed, but not all of them are required; and in the second position 202, a plurality of communication channels 11 are opened, but not all of them are required. When the communication channel 11 is closed, the entity part of the valve core 20 is blocked at one end or the middle of the communication channel 11, so that the fluid cannot flow from one end of the communication channel 11 to the other end; the communication channel 11 is opened, that is, it is no longer blocked, and the fluid can flow from one end of the communication channel 11 to the other end and flow out. The valve core 20 does not block the connecting channel 11, which mainly manifests in two forms. One is that the valve core 20 is away from the connecting channel 11, and the other is that the through part on the valve core 20 is aligned with the connecting channel 11. At this time, the fluid can pass through the through part, so that the fluid can flow from one end of the connecting channel 11 to the other end.

[0052] By setting a plurality of connecting channels 11, it can be applied to many scenarios, such as application in a liquid cooling system: a scenario in which it can be used, the plurality of connecting channels 11 of the connecting end 100 can be respectively connected to the plurality of water outlets of the water distributor, or the plurality of connecting channels 11 can be respectively connected to the plurality of water collecting outlets of the water collector; a scenario in which it can be used, the two connecting channels 11 of the connecting end 100, one is connected to the water outlet of the water distributor, and the other is connected to the water collecting outlet of the water collector, and they are located in the same circulation system. Of course, in addition to the above-mentioned application scenarios, it can also be applied to other scenarios. By simultaneously gathering a plurality of connecting channels 11 on the connecting end 100, the volume can be greatly reduced, and the use cost can be reduced.

[0053] In some embodiments, a connection end 100 is provided to cooperate with a docking end 200. It should be noted that two connection ends 100 having substantially the same or completely the same structure can be provided to serve as docking ends 200. Of course, the docking end 200 here can also be completely different from the matching connection end 100. Figure 2 The butt end and the connection end shown in the figure can be arranged oppositely and are not strictly arranged. When the structures are arranged in coordination, one is a male head and the other is a female head.

[0054] As mentioned 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, generally in a one-to-one correspondence, and of course it can also be a one-to-many or many-to-one arrangement, and there is no specific limitation. The docking port 210 can be a port of a communication channel or a port of a communication hole on the docking end 200. By docking, when the communication channel 11 is opened, the fluid in the communication channel 11 can flow into the docking port 210. The shapes of the docking points are not required to be consistent, and one can be circular and the other can be square. Of course, it can also be coaxially arranged when docking as shown in the attached figure.

[0055] The valve core 20 is movably arranged in the valve seat 10, and can be movably installed by means of sliding fit, rotation fit, etc. The valve core 20 is provided with a coupling portion 21, and the coupling portion 21 on the connecting end 100 is used to combine with the pushing portion 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 coupling method of the coupling portion 21 and the pushing portion 12 is such as magnetic attraction, insertion fit, meshing fit, etc. The specific structure of the coupling portion 21 can be set accordingly according to the different coupling methods. Specifically, the coupling portion 21 adopts a groove structure. For the convenience of description, the groove structure is referred to as the pushing groove 211, which is used for the pushing portion 12 to be inserted for coupling, so that when the pushing portion 12 moves, the valve core 20 is driven to move by the abutment between the pushing portion 12 and the groove wall of the pushing groove 211.

[0056] Specifically, when the valve core 20 moves to the first position 201, multiple connecting channels 11 are closed, which may be all or part of the connecting channels 11; and when the valve core 20 moves to the second position 202, multiple connecting channels 11 are opened, which may be all or part of the connecting channels 11.

[0057] In some embodiments, when in use, the connection end 100 and the docking end 200 are docked, and the pushing portion 12 of the docking end 200 will be combined with the coupling portion 21 on the valve core 20 to drive the valve core 20 of the connection end 100 to move when the docking end 200 moves. For example, when multiple connecting channels 11 need to be connected, the valve core 20 is pushed to move to the second position 202, and the connecting channel 11 is connected to the corresponding interface 210, and the valve core 20 is pushed to move to the first position 201, and the connecting channel 11 is disconnected from the corresponding interface 210. In the above-mentioned connection end 100, multiple connecting channels 11 are provided on the valve seat 10, so that the opening and closing of multiple connecting channels 11 can be controlled at the same time, which can effectively reduce costs compared to providing multiple connectors. In summary, the connection end 100 can improve the problem that the connection end 100 of the existing connector has a poor use effect.

[0058] In some embodiments, the valve core 20 can be rotatably arranged on the valve seat 10. In this case, each connecting channel 11 can be arranged around the rotation axis 22 of the valve core 20. It should be noted that the each connecting channel 11 can be distributed on the same circumference or on different circumferences, such as staggered distribution, so that the position of each connecting channel 11 is more compact.

[0059] The provision of a rotatable valve core 20 not only facilitates the pushing of the pushing portion 12, but also can combine the docking methods of the connecting end 100 and the docking end 200, such as performing a rotatable connection between the connecting end 100 and the docking end 200, such as a spiral connection, a rotary clamping connection, etc., so that when the connecting 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 connecting channel 11, and when the docking is completed, the valve core 20 opens each connecting channel 11, so that when the connecting end 100 and the docking end 200 are connected, the valve core 20 is driven to move, so as to realize the opening of the connecting channel 11.

[0060] The connecting channel 11 can be arranged around the rotation axis 22 of the valve core 20, and can be arranged evenly or unevenly, and the redundant space at the valve core 20 can be fully utilized. Generally speaking, in addition to the sealing structure at the boundary of the side of the valve core 20, the best way is to form a through hole in half of the area to open the connecting channel 11, and form a solid in the other half of the area to serve as a solid covering part to close the connecting channel 11.

[0061] In some embodiments, it is preferred that the connecting channels 11 are evenly arranged around the rotation axis 22 of the valve core 20. At this time, when the solid covering parts on the valve core 20 rotate between two connecting channels 11, the connecting channels 11 are cleared, and when the solid covering parts rotate to align with the corresponding connecting channels 11, the corresponding connecting channels 11 are closed.

[0062] In some embodiments, it is preferred that the central angle value a corresponding to adjacent connecting channels 11 is twice the preset rotation angle value b of the valve core 20; and the valve core 20 can be located in the second position 202 after rotating the preset rotation angle from the first position 201, so as to ensure that the physical covering part of the valve core 20 can be rotated to be directly opposite to the connecting channel 11. Of course, the preset rotation angle value can also be less than or greater than half of the central angle value corresponding to the adjacent connecting channel 11. For example, if the central angle value a corresponding to the adjacent connecting channel 11 is 120 degrees, and three connecting channels 11 are evenly arranged at this time, then the preset rotation angle value b can be 60 degrees; if the central angle value a corresponding to the adjacent connecting channel 11 is 90 degrees, and four connecting channels 11 are evenly arranged at this time, then the preset rotation angle value b can be 45 degrees.

[0063] In some embodiments, as described above, the valve seat 10 may 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 and adapt to more scenarios, it is preferred that the valve seat 10 is provided with only two communication channels 11, and the two communication channels 11 are centrally symmetrically arranged relative to the rotation axis 22 of the valve core 20. At this time, the preset rotation angle value may 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 rotating 90 degrees in the opposite direction in the second position 202. Arranging only two communication channels can be arranged more compactly than three communication channels, and can make full use of space everywhere while avoiding interference. At this time, it corresponds to the preferred rotational locking between the connecting end 100 and the docking end 200, so that when the connecting end 100 and the docking end 200 are inserted into each other to enter the initial stage of docking, the connecting end 100 and the docking end 200 are rotated 90 degrees relative to each other to complete the rotational locking, and the valve core 20 enters the second position 202.

[0064] In some embodiments, the valve core 20 can be disc-shaped, or fan-shaped, or other shapes. The specific shape can be set accordingly as needed. Generally, a sealing device is provided on the side where the valve core 20 contacts the valve seat 10, such as the attached Figure 3As shown, sealing devices are 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 includes a circular ring portion coaxially arranged with the rotation axis 22 and a partition portion arranged on the circular ring portion. The shape of the partition portion is equal to the cross-sectional shape of the connecting channel 11, such as both are circular. And because multiple connecting channels are provided, multiple partition portions are correspondingly provided, and are arranged one by one with the connecting channels. For example, when the valve core 20 rotates to the second position 202, the connecting hole 23, the connecting channel 11 and the area divided by the partition portion are coaxially arranged, and the boundary of the partition area is larger than the boundary of the connecting hole 23 to avoid protruding inside and affecting the flow of the fluid.

[0065] In some embodiments, the valve seat 10 of the connecting end 100 is used to be rotatably connected with the docking end 200. Specifically, it can be rotatably connected with the valve seat 10 of the docking end 200. The rotatable connection is such as a threaded connection, such as a rotary clamping connection, etc. When the connecting end 100 and the docking end 200 are relatively rotated to connect, the pushing portion 12 in the docking end 200 can be combined with the combining portion 21, and correspondingly drive the pushing portion 12 to move to the second position, and when disassembling, the corresponding driving portion 12 moves to the first position.

[0066] In some embodiments, as described above, the connection end 100 can be a rotationally engaged with the docking end 200. The two mating structures of the rotationally engaged structure, namely, a cam and a slot, are specifically referred to as a rotational cam and a rotational slot 13 for the sake of distinction. When the two mating structures are in a separated state, after the plug-in is achieved along the direction of the rotation axis 22, the rotational cam is mainly moved from one end of the rotational slot 13 to align with the slot, and then the rotation axis 22 is rotated. At this time, the cam is rotated into the slot, and the notch direction of the slot is perpendicular to the direction of the rotation axis 22. After the cam is rotated into the slot, one side of the cam in the direction of the rotation axis 22 abuts against the slot wall of the slot to achieve axial limiting.

[0067] Specifically, the valve seat 10 of the connecting end 100 can be provided with a rotation slot 13 for rotationally engaging with the pushing portion 12 on the docking end 200, and the coupling portion 21 is a pushing slot 211 that cooperates with the pushing portion 12 on the docking end 200, so that when the pushing portion 12 moves axially to be axially aligned with the rotation slot 13, the front end of the pushing portion 12 extends into the pushing slot 211, so that when the rotation cam at the front end of the pushing portion 12 rotates and enters the rotation slot 13, the pushing portion 12 can drive the valve core 20 having the pushing slot 211 to rotate because it is against the slot wall of the pushing slot 211.

[0068] In some embodiments, in order to facilitate the installation of the valve core 20, it is preferred that the valve seat 10 includes a valve body 14 and a valve cover 15, wherein the valve body 14 has a connection head 30 for connecting to an external channel at one end and a valve cover 15 at the other end, and is fixedly connected to the valve cover 15, such as by welding, threaded connection, etc. The valve core 20 is arranged between the valve cover 15 and the valve body 14, so that during assembly, the valve cover 15 and the valve body 14 are separated, and then the valve cover 15 and the valve body 14 sandwich the valve core 20 in the middle, and the valve cover 15 and the valve body 14 are fixedly connected, and the valve core 20 can rotate therein.

[0069] Further, the valve core 20 may be provided with a plurality of communication holes 23 corresponding to the communication channels 11, and the communication channels 11 are at least partially provided on the valve body 14. There are at least two solutions. In one solution, the communication channel 11 is only provided on the valve body 14, and 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 at the connection end 100 is directly connected with the docking port 210 at the docking end 200, such as directly connected with the communication hole 23 on the valve core 20 at the docking end 200; in another solution, a section of the communication channel 11 is respectively provided on the valve body 14 and the valve cover 15, and the valve core 20 is blocked between the two channel sections of the communication channel 11.

[0070] When the valve core 20 rotates until the communicating hole 23 is aligned with the communicating channel 11, the communicating channel 11 is opened; when the valve core 20 rotates until the communicating hole 23 is offset from the communicating channel 11 so that the physical part of the valve core 20 blocks the communicating channel 11, the communicating channel 11 is closed.

[0071] The connecting passage 11 and the connecting hole 23 preferably have the same cross section, so that when aligned, the hole wall surface is located on the same extension surface. If the connecting passage 11 and the connecting hole 23 are both circular in cross section, the diameters of the two are the same. If they are both rectangular, the size and shape are equal, and when aligned, the edges are aligned. Of course, they can also be of different shapes.

[0072] In some embodiments, a locking pin 40 for preventing the valve core 20 from moving relative to the valve seat 10 may be provided on the valve seat 10; wherein the locking pin 40 is axially movably connected to the valve seat 10, and generally the locking pin 40 has an operating key 41 exposed to the outside for easy operation. A locking hole 24 is provided on the valve core 20, so that when the valve core 20 rotates to the first position 201, the locking pin 40 can move to enter the locking hole 24. In order to facilitate operation, a stop mechanism is preferably provided here, so that when the locking pin 40 moves to the exit locking position, the locking pin 40 can be kept in the current position without the elastic device driving the locking pin 40 forward, and when the stop 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.

[0073] In some embodiments, it is preferred that the locking hole 24 and the coupling portion 21 are both arranged radially outside the area where the connecting hole 23 is located, so as to leave a central area for better arrangement of the connecting hole 23 and the physical covering portion.
