[0020] According to some embodiments of the present invention, the fluid connector further includes a second elastic element connected to the first connector and the first operating handle; when the first operating handle is released from pressure, the second elastic element is used to reset the first operating handle to its initial position before being pressed.

[0021] According to some embodiments of the present invention, the first operating handle has an oblong hole along the longitudinal direction of the first connector;

[0022] The fluid connector further includes a positioning pin, which is slidably disposed on the first connector along the longitudinal direction of the first connector and extends from the end of the first connector near the second connector. A positioning shaft is provided on the side of the positioning pin, which passes through the waist-shaped hole. The second elastic element is connected to the positioning pin and is used to provide the positioning pin with a restoring force toward the second connector.

[0023] When the first connector separates from the second connector, the second elastic element pushes the first operating handle toward the second connector to reset to its initial position via the positioning shaft of the positioning pin.

[0024] According to some embodiments of the present invention, the latch is provided with a receiving groove along its length direction, and the first elastic member is disposed in the receiving groove; wherein, one end of the latch is a plug-in portion, the first connector has a guide protrusion located in the receiving groove, one end of the first elastic member abuts against one end of the receiving groove near the plug-in portion, and the other end abuts against the guide protrusion.

[0025] According to some embodiments of the present invention, both the first connector and the second connector include:

[0026] A valve seat, the valve seat having a mating end face and a fluid channel penetrating the mating end face, the locking assembly being disposed on the valve seat of the first connector;

[0027] A spherical valve core has a rotating shaft on its side. The spherical valve core is disposed in the fluid passage. The rotating shaft is rotatably connected to the side wall of the valve seat and extends at least partially to the outside of the valve seat. The outer end of the rotating shaft is configured to be actuated so that the spherical valve core can be rotated to open or close the fluid passage.

[0028] According to some embodiments of the present invention, both the first connector and the second connector further include: a second operating handle, the second operating handle being connected to the outer end of the rotating shaft, and the second operating handle being operable to drive the rotating shaft to rotate.

[0029] According to some embodiments of the present invention, the first connector and the second connector further include a positioning component, the positioning component comprising:

[0030] A push rod is slidably mounted on the second operating handle, and one end of the push rod is provided with a positioning slope.

[0031] The ball bearing is provided with a mounting hole on the side of the second operating handle near the valve seat. The ball bearing is movably disposed in the mounting hole and fits against the positioning inclined surface.

[0032] An operating push rod is slidably disposed on the second operating handle. One of the operating push rod and the push rod is provided with a first transmission inclined surface so as to fit against the other. The operating push rod can be pressed to push the push rod away from the ball through the first transmission inclined surface.

[0033] A first spring, connected to the second operating handle and the top rod, is used to keep the positioning inclined surface in contact with the ball.

[0034] The valve seat has a first positioning groove and a second positioning groove on its side. When the ball valve core is in the open state relative to the fluid channel, the ball is embedded in the first positioning groove under the action of the push rod. When the ball valve core is in the closed state relative to the fluid channel, the ball is embedded in the second positioning groove under the action of the push rod.

[0035] According to some embodiments of the present invention, the fluid channel forms a docking port on the docking end face, the docking end face is provided with a guide groove and a protruding first insertion rod portion, the guide groove extending around the docking port as the center;

[0036] Both the first connector and the second connector further include: a first transmission member and a second transmission member. The first transmission member is linearly slidably disposed inside the guide groove, and the second transmission member is connected to the outer end of the rotating shaft and is connected to the first transmission member in a transmission manner. The first transmission member can drive the rotating shaft to rotate through the second transmission member when sliding.

[0037] When the mating end faces of the two valve seats are aligned, the first insert rod extends into the guide groove and is inserted into the first transmission component. When the two valve seats rotate relative to each other in the forward direction, the first insert rod moves circumferentially along the guide groove and drives the rotating shaft to rotate forward via the first and second transmission components, thereby driving the spherical valve core to rotate from the closed position to the open position. When the two valve seats rotate relative to each other in the reverse direction, the first insert rod moves circumferentially along the guide groove and drives the rotating shaft to rotate in the reverse direction via the first and second transmission components, thereby driving the spherical valve core to rotate from the open position to the closed position.

[0038] According to some embodiments of the present invention, the first transmission member has a first tooth on the side near the rotating shaft, and the second transmission member has a second tooth in its circumferential direction, wherein the first tooth meshes with the second tooth; or,

[0039] One end of the second transmission component is rotatably connected to the first transmission component, and the other end is provided with a sliding hole. The rotating shaft passes through the sliding hole and is circumferentially restricted to the second transmission component through the sliding hole.

[0040] According to some embodiments of the present invention, the mating end face is provided with a protruding second insertion rod portion and a connecting slot, the connecting slot being circumferentially extended with the mating port as the center;

[0041] When the two connectors rotate in opposite directions, the second insert portion is engaged in the connecting slot, so that the two valve seats are axially locked.

[0042] When the two connectors rotate in opposite directions, the second insert part releases its grip on the connecting groove, thereby releasing the two valve seats from axial locking.

[0043] Secondly, embodiments of this application provide a liquid cooling device, including the fluid connector described above.

[0044] Compared with existing technologies, the technical solution provided in this application has at least the following advantages:

[0045] When the first and second connectors of the connector are in a plug-in connection state, the locking tongue is located in the first position under the action of the first elastic element to engage with the second connector, thereby axially restricting the first and second connectors and effectively ensuring a stable plug-in connection between the first and second connectors, so as to effectively avoid leakage between the first and second connectors.

[0046] When it is necessary to axially separate the first and second connectors of the connector, the locking tongue is switched from the first position to the second position by operating the locking tongue. At this time, the locking tongue releases the axial restriction between the first and second connectors, and the operator can easily axially separate the first and second connectors.

[0047] In summary, the fluid connector provided in this application is more convenient to operate when separation is required. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0068] The present invention will now be described in further detail with reference to the accompanying drawings.

[0069] Please refer to Figure 1, which shows a fluid connector provided in an embodiment of the present invention, including a first connector 101 and a second connector 102. The first connector 101 and the second connector 102 can be plugged into each other to enable the connection of two fluid pipelines.

[0070] Referring to Figures 2 and 4, to ensure a secure connection between the first connector 101 and the second connector 102, the fluid connector further includes a locking assembly 200. The locking assembly 200 is used to maintain a secure connection between the first connector 101 and the second connector 102. Specifically, the locking assembly 200 includes a locking tongue 210 and a first elastic member 220. The locking tongue 210 is laterally slidably disposed on the first connector 101 to switch between a first position and a second position. The first elastic member 220 is connected to the first connector 101 and the locking tongue 210 to hold the locking tongue 210 in the first position, and the locking tongue 210 can be operated to switch from the first position to the second position. When the locking tongue 210 is in the first position under the action of the first elastic member 220, the locking tongue 210 is in a laterally extended state. At this time, the locking tongue 210 can engage with the first insertion part 116 or the second insertion part 114 of the second connector 102 to restrict the axial separation of the first connector 101 and the second connector 102. When the locking tongue 210 is in the second position, the locking tongue 210 is in a laterally retracted state, and the locking tongue 210 releases the axial restriction between the first connector 101 and the second connector 102.

[0071] In practical applications, when the first connector 101 and the second connector 102 of the above-mentioned connector are plugged in, the locking tongue 210 is held in the first position under the action of the first elastic member 220, or in other words, the locking tongue 210 is held in a laterally extended state under the action of the first elastic member 220, so as to engage with the second connector 102, thereby axially restricting the first connector 101 and the second connector 102, and thus effectively ensuring that the first connector 101 and the second connector 102 are firmly plugged in, so as to avoid leakage between the first connector 101 and the second connector 102.

[0072] When it is necessary to axially separate the first connector 101 and the second connector 102 of the connector, the operator can easily push the locking tongue 210 to overcome the elastic force of the first elastic element 220, so as to slide from the first position to the second position. That is, by operating the locking tongue 210, the locking tongue 210 is switched from the first position to the second position, or in other words, the locking tongue 210 switches from a laterally extended state to a laterally retracted state. At this time, the locking tongue 210 releases the axial restriction between the first connector 101 and the second connector 102, and the operator can easily pull the first connector 101 and the second connector 102 apart. Of course, if the operator releases the push on the locking tongue 210, the locking tongue 210 returns from the second position to the first position under the action of the first elastic element 220, or in other words, the locking tongue 210 switches from a laterally retracted state to a laterally extended state. Thus, the locking tongue 210 can be used again to axially restrict the first connector 101 and the second connector 102. As can be seen from the above, the fluid connector provided by the present invention is more convenient to operate when separation is required.

[0073] To facilitate the switching of the latch 210 from the first position to the second position, in some embodiments, referring to Figures 3 to 6, the locking assembly 200 further includes a first operating handle 230. The first operating handle 230 is movably connected to the first connector 101 and is drive-connected to the latch 210. Specifically, the first operating handle 230 and the latch 210 can be directly drive-connected, or a transmission structure can be used to achieve the drive-connection between the two. The first operating handle 230 can be operated to drive the latch 210 to switch from the first position to the second position (refer to Figures 3 and 4, or Figures 5 and 6). Of course, the latch 210 can also be provided with an operating part, allowing the operator to directly operate the latch 210 to slide laterally, so that the latch 210 can slide from the first position to the second position.

[0074] Understandably, by providing a first operating handle 230, when it is necessary to separate the first connector 101 from the second connector 102, the operator can conveniently operate the first operating handle 230 to drive the locking tongue 210 to slide from a first position to a second position, that is, the locking tongue 210 switches from a laterally extended state to a laterally retracted state. At this time, the locking tongue 210 releases the axial restriction between the first connector 101 and the second connector 102, and the operator can conveniently separate the first connector 101 from the second connector 102.

[0075] In some possible embodiments, the first operating handle 230 is slidably or rotatably connected to the first connector 101. With this configuration, the operator can easily operate the first operating handle 230 to drive the locking tongue 210 to slide from the first position to the second position, thereby achieving axial unlocking between the first connector 101 and the second connector 102.

[0076] In one specific embodiment, referring to Figures 3 to 6, the side of the first connector 101 is provided with a mounting groove (not shown in the figures) along its longitudinal direction. The first operating handle 230 is slidably disposed on the inner side of the first connector 101 along the longitudinal direction of the first connector 101 through the mounting groove, and at least partially exposed on the outer side of the first connector 101 for operation by the operator. Simultaneously, one of the first operating handle 230 and the locking tongue 210 is provided with a guide surface 233, and the other is provided with a pushing part 213. The first elastic member 220 acts laterally toward the inner side of the first connector 101 on the locking tongue 210, so that the pushing part 213 and the guide surface 233 remain in contact. When the first operating handle 230 is pressed and displaced along the longitudinal direction of the first connector 101, the first operating handle 230 uses the force between the guide surface 233 and the pushing part 213 to push the locking tongue 210 from a first position to a second position, thereby achieving axial unlocking between the first connector 101 and the second connector 102.

[0077] Specifically, the first operating handle 230 has two extension arms 231 arranged side-by-side and spaced apart (see Figure 7). The two extension arms 231 extend along the longitudinal direction of the first connector 101, forming a guide gap 232 between them. The locking tongue 210 slides laterally through the guide gap 232 between the two extension arms 231. Simultaneously, one end of the locking tongue 210 is provided as a plug-in portion 211, which is used to engage with the first plug-in portion 116 or the second plug-in portion 114 of the second connector 102. A limiting portion 214 and the aforementioned pushing portion 213 are spaced apart on the side of the locking tongue 210, with the limiting portion 214 located between the pushing portion 213 and the plug-in portion 211. The extension arm 231 is located between the limiting portion 214 and the pushing portion 213, allowing the locking tongue 210 to slide laterally within a set range between the limiting portion 214 and the pushing portion 213. The side of the extension arm 231 closest to the pushing portion 213 forms the aforementioned guide surface 233. Furthermore, the latch 210 has a receiving groove 212 along its length direction, and the first elastic member 220 can be a spring, which is disposed in the receiving groove 212 along its length direction. One end of the first elastic member 220 abuts against the end of the receiving groove 212 near the insertion portion 211. The first connector 101 has a guide protrusion 1113 embedded in the receiving groove 212, and the other end of the first elastic member 220 abuts against the guide protrusion 1113. Thus, the first elastic member 220 abuts against the first connector 101 and the latch 210, providing elastic force for the extension of the latch 210 and for maintaining it in the extended state (see Figures 4 and 8). As can be seen from the above, the locking assembly 200 adopts the above-described structural form, the locking assembly 200 has a compact structure, and the locking assembly 200 can be compactly assembled inside the first connector 101.

[0078] In practical application, the operator presses the first operating handle 230 and slides it along the longitudinal direction of the first connector 101. The first operating handle 230, with the guide slope 2333 of the guide surface 233, acts laterally outward on the pushing part 213 of the locking tongue 210. As a result, the first elastic element 220 is compressed, and the locking tongue 210 slides laterally outward under the action of the first operating handle 230, thereby releasing the axial restriction between the first connector 101 and the second connector 102, and thus allowing the first connector 101 and the second connector 102 to be easily separated.

[0079] Further referring to Figures 5 to 7, along the longitudinal direction of the first connector 101, the guide surface 233 includes a first longitudinal surface 2331, a guide inclined surface 2333, and a second longitudinal surface 2332 connected in sequence. The first longitudinal surface 2331 extends along the longitudinal direction of the first connector 101, and the second longitudinal surface 2332 extends along the longitudinal direction of the first connector 101. The first longitudinal surface 2331 is lower than the second longitudinal surface 2332. The guide inclined surface 2333 is obliquely connected to the first longitudinal surface 2331 and the second longitudinal surface 2332. Between the longitudinal surfaces 2332; wherein, when the pushing part 213 is attached to the first longitudinal surface 2331, the locking tongue 210 engages with the first insertion part 116 of the second connector 102 (see Figure 5) to achieve axial locking between the first connector 101 and the second connector 102; when the pushing part 213 is attached to the second longitudinal surface 2332, the locking tongue 210 releases the axial restriction between the first connector 101 and the second connector 102 (see Figure 6) to allow the first connector 101 and the second connector 102 to be pulled apart.

[0080] Specifically, when the first connector 101 and the second connector 102 are connected, the locking tongue 210 extends along the lateral direction of the first connector 101 under the action of the first elastic member 220, thereby engaging with the second connector 102. When it is necessary to separate the first connector 101 and the second connector 102, the operator pushes the first operating handle 230 to slide along the longitudinal direction of the first connector 101. The pushing part 213 slides from the first longitudinal surface 2331 along the guide slope 2333 to the second longitudinal surface 2332. The first operating handle 230 pushes the locking tongue 210 to slide laterally outward through the guide slope 2333, thereby releasing the axial restriction of the locking tongue 210 between the first connector 101 and the second connector 102, and thus the first connector 101 and the second connector 102 can be separated.

[0081] Furthermore, the guide surface 233 also includes a first limiting surface 2334 and a second limiting surface 2335, wherein the first limiting surface 2334 is connected to the end of the first longitudinal surface 2331 away from the guide slope 2333 and extends along the transverse direction of the first joint 101; the second limiting surface 2335 is connected to the end of the second longitudinal surface 2332 away from the guide slope 2333 and extends along the transverse direction of the first joint 101. Therefore, the first limiting surface 2334 and the second limiting surface 2335 are used to restrict the pushing part 213 from sliding away from both ends of the guide surface 233, thereby ensuring that the pushing part 213 slides between the first longitudinal surface 2331, the guide inclined surface 2333 and the second longitudinal surface 2332, and thus ensuring that the first operating handle 230 can stably push the locking tongue 210 to switch between the first position and the second position; at the same time, the pushing part 213 includes a first positioning surface 2131, a second positioning surface 2132, a third positioning surface 2133 and a fourth positioning surface 2134 connected in sequence, wherein, when the locking tongue 210 is in the first position, the first positioning surface 2131 and the first limiting surface 2334 The locking mechanism is configured such that the second positioning surface 2132 is fitted to the first longitudinal surface 2331, and the third positioning surface 2133 is fitted to the guide slope 2333 (see Figure 5). When the latch 210 is in the second position, the second positioning surface 2132 is fitted to the second longitudinal surface 2332, and the fourth positioning surface 2134 is fitted to the second limiting surface 2335 (see Figure 6). With this configuration, the first operating handle 230 can stably keep the latch 210 in the first and second positions. The fitting of the third positioning surface 2133 to the guide slope 2333 can effectively ensure that the pushing part 213 slides smoothly from the first longitudinal surface 2331 to the second longitudinal surface 2332.

[0082] It should be noted that a first longitudinal surface 2331 and a first limiting surface 2334 are provided on the first operating handle 230. Under the action of the first elastic member 220, the first longitudinal surface 2331 and the first limiting surface 2334 can effectively maintain the position of the locking tongue 210, thereby maintaining the axial restriction between the first connector 101 and the second connector 102. Under the action of the first elastic member 220, the second longitudinal surface 2332 and the second limiting surface 2335 can effectively maintain the position of the locking tongue 210, thereby making the locking tongue 210 unlocked from the first connector 101 and the second connector 102, thus facilitating the insertion and removal between the first connector 101 and the second connector 102.

[0083] To enable the first operating handle 230 to reset after being pressed, in some embodiments, referring to Figures 5 to 8, the fluid connector further includes a second elastic element 240. The second elastic element 240 may be a spring. One end of the second elastic element 240 abuts against the first connector 101, and the other end abuts against the first operating handle 230. Thus, when the first operating handle 230 is released from pressing, the second elastic element 240 is used to reset the first operating handle 230 to its initial position. Specifically, when the second elastic element 240 pushes the first operating handle 230 toward its initial position, the first operating handle 230 gradually releases its restriction on the locking tongue 210. Consequently, the locking tongue 210 gradually slides laterally under the action of the first elastic element 220, i.e., slides toward the first position, so that it can be used again for axial locking between the first connector 101 and the second connector 102.

[0084] Furthermore, the first operating handle 230 has an oblong hole 234 along the longitudinal direction of the first connector 101. The fluid connector also includes a positioning pin 250, which is slidably disposed on the first connector 101 along the longitudinal direction of the first connector 101, with one end of the positioning pin 250 extending from the end of the first connector 101 near the second connector 102 (see Figure 2). Simultaneously, the positioning pin 250 is located on one side of the first operating handle 230, and a positioning shaft 251 is provided on the side of the positioning pin 250, passing through the oblong hole 234. The second elastic member 240 is connected to the first connector 101 and the inner end of the positioning pin 250, providing a restoring force to the positioning pin 250 toward the second connector 102; when the first connector 101 separates from the second connector 102, the second elastic member 240 pushes the first operating handle 230 back to its initial position toward the second connector 102 via the positioning shaft 251 of the positioning pin 250.

[0085] Specifically, in the first stage, when the first connector 101 and the second connector 102 are not connected, one end of the positioning pin 250 extends from the mating end of the first connector 101 near the second connector 102, the positioning shaft 251 is located at the end of the oblong hole 234 near the second connector 102, the pushing part 213 is located at the position of the first longitudinal surface 2331 and the first limiting surface 2334, and the locking tongue 210 is in a laterally extended state under the action of the first elastic member 220 (see Figure 5). In the second stage, the first connector 101 and the second connector 102 are inserted and connected. The positioning pin 250 retracts towards the inside of the first connector 101 under the action of the second connector 102. Correspondingly, the positioning shaft 251 slides along the oblong hole to the end of the oblong hole away from the second connector 102 (see Figure 3), and the locking tongue 210 engages with the second connector 102, thereby ensuring a stable insertion and connection between the first connector 101 and the second connector 102. In the third stage, when the operator pushes the first operating handle 230 away from the longitudinal direction of the second connector 102, the positioning shaft 251 is again located at the end of the oblong hole near the second connector 102 (see Figure 6). Simultaneously, the first operating handle 230 uses the guide ramp 2333 to push the locking tongue 210 outward, releasing the locking tongue 210 from the restriction between the first connector 101 and the second connector 102. In the fourth stage, if the operator releases the pressure on the first operating handle 230, and the positioning shaft 251 is located at the end of the oblong hole near the second connector 102 (see Figures 4 and 6), when the first connector 101 and the second connector 102 separate, the second elastic element 240 pushes the positioning pin 250 to slide axially toward the second connector 102. The positioning pin 250 uses the positioning shaft 251 to push the first operating handle 230 back to its original position toward the second connector 102. The locking tongue 210, under the action of the first elastic element 220, returns to its first position, so that it can be used again to lock the second connector 102.

[0086] Understandably, after the operator releases the pressure on the first operating handle 230, because the first connector 101 and the second connector 102 are not separated, the positioning pin 250 remains in a retracted state under the action of the second connector 102. Consequently, the second elastic element 240 cannot act on the first operating handle 230, preventing the first operating handle 230 from resetting. Therefore, the locking tongue 210 remains unlocked from the second connector 102, facilitating the operator to separate the first connector 101 from the second connector 102. Thus, the operator does not need to keep the first operating handle 230 pressed to keep the locking tongue 210 unlocked, making it more convenient to use.

[0087] In some embodiments, referring to FIG1, the structures of the first connector 101 and the second connector 102 are generally the same. Therefore, this application will uniformly describe the specific structures of the first connector 101 and the second connector 102, and will not describe the first connector 101 and the second connector 102 separately.

[0088] Specifically, referring to Figures 9 and 10, the first connector 101 and the second connector 102 are both collectively referred to as connectors. Each connector includes a valve seat 110 and a spherical valve core 120. The valve seat 110 is generally cylindrical, with one end designated as a mating end face 115. The valve seat 110 has a fluid channel 113 along its longitudinal direction, forming a mating port at the mating end face 115. A locking assembly 200 is disposed on the valve seat 110 of the first connector 101. The spherical valve core 120 is generally spherical, with a rotating shaft portion 122 on its opposite side. The spherical valve core 120 is disposed within the fluid channel 113. The rotating shaft portion 122 passes through the side wall of the valve body 111 of the valve seat 110 and extends at least partially to the outside of the valve body 111. The spherical valve core 120 is rotatably connected to the valve body 111 of the valve seat 110 via the rotating shaft portion 122. The rotating shaft 122 extends at least partially to the outside of the valve seat 110. The outer end of the rotating shaft 122 is configured to be driven so that the ball valve core 120 rotates within the fluid passage 113. During rotation, the ball valve core 120 closes and opens the fluid passage 113.

[0089] The rotating shaft 122 is snapped into the ball valve core 120, or the two are integrated, or connected in other ways.

[0090] In practical applications, when the first connector 101 and the second connector 102 are plugged in, the mating end faces 115 of the two valve seats 110 are in contact, and the mating ports of the two fluid channels 113 are connected. Furthermore, by driving the outer end of the rotating shaft 122, the two ball valve cores 120 respectively switch the flow channel 113 from a closed state to an open state. If it is necessary to separate the first connector 101 and the second connector 102, by driving the outer end of the rotating shaft 122, the two ball valve cores 120 respectively switch the flow channel 113 from an open state to a closed state, thereby facilitating subsequent separation of the first connector 101 and the second connector 102.

[0091] In some embodiments, the spherical valve core 120 has a fluid through-hole 121 that extends through both sides of the spherical valve core 120. When the spherical valve core 120 is in the open state relative to the fluid channel 113, the two ports of the fluid through-hole 121 face the two ports of the fluid channel 113, that is, the two ports of the fluid through-hole 121 are connected to the fluid channel 230, thereby keeping the fluid channel 113 in the open state. When the spherical valve core 120 is in the closed state relative to the fluid channel 113, the two ports of the fluid channel 113 face the channel wall of the fluid channel 113, thereby keeping the fluid channel 113 in the closed state. In other embodiments, the side wall of the spherical valve core 120 may have a notch, which can also replace the fluid through-hole 121 described above.

[0092] To enable the valve core to switch between the open and closed positions, in one possible embodiment, referring to Figures 9 to 12, both the first connector 101 and the second connector 102 further include a second operating handle 130. The second operating handle 130 is located outside the valve seat 110, with one end connected to the outer end of the rotating shaft portion 122. The second operating handle 130 can be operated to drive the rotating shaft portion 122 to rotate. It is understood that by providing the second operating handle 130 at the outer end of the rotating shaft portion 122, during application, the operator can conveniently hold the second operating handle 130, thereby driving the ball valve core 120 to rotate via the rotating shaft portion 122, thus switching the valve core between the open and closed positions, and consequently opening or closing the fluid passage 113.

[0093] Furthermore, the connector also includes a positioning component 140. The side of the valve seat 110 is provided with a first positioning groove 1111 and a second positioning groove 1112 into which the positioning component 140 is inserted. When the ball valve core 120 is in the open state relative to the fluid passage 113, the ball 146 of the positioning component 140 engages with the first positioning groove 1111, locking the position of the second operating handle 130, thereby keeping the ball valve core 120 in the open state relative to the fluid passage 113. When the ball valve core 120 is in the closed state relative to the fluid passage 113, the ball 146 of the positioning component 140 engages with the second positioning groove 1112, locking the position of the second operating handle 130, thereby keeping the ball valve core 120 in the closed state relative to the fluid passage 113.

[0094] Specifically, the positioning assembly 140 includes a push rod 141, an operating push rod 142, a ball bearing 146, a first spring 144, and a second spring 145. The push rod 141 is slidably disposed on the inner side of the second operating handle 130 along the length direction of the second operating handle 130, and the end of the push rod 141 is provided with a positioning inclined surface 1411. The second operating handle 130 is provided with a mounting hole 131 on the side near the valve seat 110. The ball bearing 146 is installed in the mounting hole 131 and is fitted against the positioning inclined surface 1411. The ball bearing 146 is used to be embedded in the first positioning groove 1111 or the second positioning groove 1112. The operating push rod 142 is slidably disposed inside the second operating handle 130, with the pressing end of the operating push rod 142 exposed on the side of the second operating handle 130. One of the operating push rod 142 and the push rod 141 is provided with a first transmission inclined surface 1421 to fit against the other. In application, the pressing end of the operating push rod 142 is pressed inward to drive the push rod away from the ball bearing 146. Furthermore, a first elastic element 220 is connected to the valve seat 110 and the push rod 141, and the first elastic element 220 is used to keep the push rod 141 and the operating push rod 142 in contact. A second spring 145 is connected to the valve seat 110 and the operating push rod 142. After the operator releases the pressure on the operating push rod 142, the pressing end of the operating push rod 142 pops out under the action of the second spring 145.

[0095] Furthermore, the positioning assembly 140 also includes a pusher 143, which is connected to the inner end of the operating push rod 142. One of the operating push rod 142 and the push rod 141 is provided with a second transmission inclined surface 1431 so as to fit against the other. After the operating push rod 142 stops being pressed, the pusher 143 is reset under the action of the second spring 145. During the reset process, the operating push rod 142 can use the second transmission inclined surface 1431 to act on the push rod 141, thereby causing the push rod 141 to move toward the ball 146.

[0096] In practical applications, when the position of the ball valve core 120 needs to be rotated, the operator, while holding the second operating handle 130, presses the pressing end of the operating push rod 142 inwards towards the second operating handle 130. The operating push rod 142 acts on the push rod 141 via the first transmission inclined surface 1421, causing the push rod 141 to slide away from the ball 146. The positioning inclined surface 1411 at the end of the push rod 141 releases the restriction on the ball 146. Therefore, when the operator rotates the second operating handle 130, the ball 146 can retract inwards towards the mounting hole 131, thereby separating from the first positioning groove 1111 or the second positioning groove 1112, and thus the second operating handle 130 can be rotated. When the operator stops pressing the operating push rod 142, the push rod 141 slides back toward the ball 146 under the action of the first spring 144, and pushes out the ball 146 using the positioning ramp 1411. The ball 146 can then re-enter the first positioning groove 1111 or the second positioning groove 1112, thereby maintaining the position of the second operating handle 130. At the same time, the second spring 145 drives the pressing end of the operating push rod 142 to pop out again for the operator to press next. Moreover, during the reset process, the operating push rod 142 also acts on the push rod 141 using the second transmission ramp 1431, so that the positioning ramp 1411 of the push rod 141 can maintain the force on the ball 146, thereby allowing the ball 146 to be stably embedded in the first positioning groove 1111 or the second positioning groove 1112, thus maintaining the position of the second operating handle 130.

[0097] To enable the valve core to switch between open and closed states, in one possible embodiment, referring to Figures 1, 13, and 14, the mating end face 115 is provided with a guide groove 1151 and a protruding first insert portion 116. The end of the first insert portion 116 is provided with a first limiting flange 1161. The guide groove 1151 extends circumferentially with the mating port as the center. The connector also includes a first transmission member 150 and a second transmission member 160. The first transmission member 150 is generally block-shaped and located at a position corresponding to the guide groove 1151, sliding linearly inside the guide groove 1151, with its sliding direction perpendicular to the longitudinal direction of the valve seat 110. A slot 152 is provided on the side of the first transmission member 150 near the guide groove 1151, with the length direction of the slot 152 perpendicular to the sliding direction of the first transmission member 150. When the two connectors are connected, the first insertion rod 116 is inserted into the slot 152 and can slide relative to the first transmission member 150 along the length of the slot 152. The second transmission member 160 is connected to the rotating shaft 122 and the first transmission member 150. When the first transmission member 150 slides, it drives the rotating shaft 122 to rotate through the second transmission member 160. When the two valve seats 110 rotate in opposite directions, the first insert rod portion 116 moves circumferentially along the guide groove 1151, and the first limiting protrusion 1161 of the first insert rod portion 116 is engaged with the inner side of the valve cover 112 of the valve seat 110, and the locking tongue 210 can be engaged with the first limiting protrusion 1161 of the first insert rod portion 116. At the same time, when the two valve seats 110 rotate in opposite directions, the rotating shaft portion 122 is driven to rotate in the forward direction through the first transmission member 150 and the second transmission member 160, so as to drive the ball valve core 120 to rotate from the closed position to the open position. When the two valve seats 110 rotate in opposite directions, the first insert rod portion 116 moves circumferentially along the guide groove 1151, and the rotating shaft portion 122 is driven to rotate in the reverse direction through the first transmission member 150 and the second transmission member 160, so as to drive the ball valve core 120 to rotate from the open position to the closed position.

[0098] Specifically, when the two connectors are aligned or in a connected state, the first insertion rod 116 is inserted into the slot 152 of the first transmission member 150 through the guide groove 1151. When the two connectors rotate relative to each other in either the forward or reverse direction, the first insertion rod 116 pushes the first transmission member 150 to slide linearly. The length direction of the slot 152 is perpendicular to the sliding direction of the first transmission member 150. During the sliding process of the first transmission member 150, the first insertion rod 116 slides along the length direction of the slot 152. Therefore, while the first insertion rod 116 moves along the arc of the guide groove 1151, it can also push the first transmission member 150 to slide without interference. Since the first transmission member 150 is connected to the rotating shaft 122 via the second transmission member 160, the first transmission member 150 acts on the rotating shaft 122 through the second transmission member 160 during the sliding process, thereby driving the ball valve core 120 to rotate, and thus realizing the closing and opening of the fluid channel 113.

[0099] In one specific embodiment, the first transmission member 150 has a first tooth 151 on the side near the rotating shaft 122, and multiple first teeth 151 are arranged sequentially along the sliding direction of the first transmission member 150. Simultaneously, the second transmission member 160 is generally wheel-shaped, and second teeth 161 are arranged sequentially in its circumferential direction. The first teeth 151 and the second teeth 161 mesh with each other. Specifically, the first transmission member 150 is equivalent to a rack, and the second transmission member 160 is equivalent to a gear. When the first insert rod 116 pushes the first transmission member 150 to slide linearly, the first transmission member 150 drives the second transmission member 160 to rotate. The second transmission member 160 drives the ball valve core 120 to rotate synchronously through the rotating shaft 122, thereby opening or closing the fluid channel 113.

[0100] In a different embodiment than the aforementioned structure of the first transmission member 150 and the second transmission member 160, the second transmission member 160 is a rod-shaped body. One end of the second transmission member 160 is rotatably connected to the first transmission member 150, and the other end is provided with a sliding hole. The length direction of the sliding hole is the same as the length direction of the second transmission member 160 (not shown in the figure). The side of the rotating shaft portion 122 is provided with a positioning plane. The rotating shaft portion 122 passes through the sliding hole, and the positioning plane of the rotating shaft portion 122 is fitted against the inner wall of the sliding hole. Thus, the rotating shaft portion 122 and the second transmission member 160 are slidably disposed and circumferentially restricted.

[0101] Specifically, when the first insertion rod 116 pushes the first transmission member 150 to slide linearly, the second transmission member 160 rotates relative to the first transmission member 150, and the rotating shaft 122 slides relative to the second transmission member 160 along the length direction of the sliding hole. Thus, the second transmission member 160 drives the rotating shaft 122 to rotate. When the rotating shaft 122 rotates, it drives the ball valve core 120 to rotate synchronously, thereby opening and closing the fluid channel 113.

[0102] In some embodiments, referring to Figures 1, 13, and 14, the mating end face 115 is provided with a protruding second insertion rod portion 114, and one or more second insertion rod portions 114 are provided. The end of the second insertion portion 211 is provided with a second limiting flange 1141. Simultaneously, the mating end face 115 is also provided with a connecting groove 1152, which extends circumferentially around the mating port. The number of connecting grooves 1152 and second insertion rod portions 114 is equal. In the circumferential direction around the mating port, the connecting grooves 1152 and second insertion rod portions 114 are arranged alternately. The guide groove 1151 and the first insertion rod portion 116 are located around the periphery of the connecting groove 1152; more precisely, the guide groove 1151 and the first insertion rod portion 116 are located in the edge region of the mating end face 115, but are not limited to the edge region of the mating end face 115.

[0103] In practical applications, when the two connectors are aligned, the second insert rod portions 114 of the two valve seats 110 respectively extend into their respective connecting grooves 1152, and the locking tongue 210 can engage with the second limiting protrusion 1141 of the second insert rod portion 114. When the two connectors rotate in the forward direction relative to each other, the second insert rod portion 114 is engaged with the connecting groove 1152 by rotation. Therefore, the second limiting protrusion 1141 of the second insert rod portion 114 is engaged with the inner side of the valve cover 112 of the valve seat 110, thereby achieving axial locking of the two valve seats 110 and connecting the two connectors. When the two connectors rotate in the reverse direction relative to each other, the second insert rod portion 114 is released from engagement with the connecting groove 1152 by rotation. Therefore, the two valve seats 110 are released from axial locking, thereby allowing the two connectors to be disengaged.

[0104] As can be seen from the above, when the two connectors rotate relative to each other in the forward direction, the second insertion rod portion 114 moves circumferentially along the connecting groove 1152 in the forward direction, thereby connecting the two connectors; and the first insertion rod portion 116 moves circumferentially in the forward direction along the guide groove 1151, thereby driving the ball valve core 120 to rotate through the first transmission member 150 and the second transmission member 160, thereby opening the fluid passage 113. When the two connectors rotate relative to each other in the reverse direction, the second insertion rod portion 114 moves circumferentially in the reverse direction along the connecting groove 1152, thereby releasing the restriction between the second insertion rod portion 114 and the connecting groove 1152; and the first insertion rod portion 116 moves circumferentially in the reverse direction along the guide groove 1151, thereby driving the ball valve core 120 to rotate in the other direction through the first transmission member 150 and the second transmission member 160, thereby closing the fluid passage 113. As further explained above, during the installation and removal of the two connectors, the ball valve core 120 rotates automatically along with the installation and removal of the connectors, thereby realizing the automatic opening and closing of the fluid channel 113 by the ball valve core 120.

[0105] In some specific embodiments, the valve seat 110 includes a valve body 111 and a valve cover 112. The valve body 111 has a first channel extending along its longitudinal direction and penetrating both ends of the valve body 111. The valve cover 112 has a second channel and is connected to one end of the valve body 111. The first channel and the second channel are connected to form the aforementioned fluid channel 113. The mating end face 115 is the surface of the valve cover 112 away from the valve body 111. A guide groove 1151 is disposed on the valve cover 112 and penetrates the inner side of the valve cover 112. A spherical valve core 120 is disposed in the first channel. The rotating shaft portion 122 on the side of the spherical valve core 120 is rotatably connected to the side wall of the valve body 111 and extends to the outer side of the valve body 111. The first insert rod portion 116 and the second insert rod portion 114 are connected to the end of the valve body 111 near the valve cover 112 and pass through the valve cover 112, or the first insert rod portion 116 and the second insert rod portion 114 are directly connected to the valve cover 112.

[0106] Based on the above embodiments, this application discloses a liquid cooling device, referring to Figures 1 to 4, which includes the fluid connector described above.

[0107] It is understandable that, since the liquid cooling device includes the aforementioned fluid connector, when the first connector 101 and the second connector 102 are connected, the locking tongue 210 is engaged with the second connector 102 under the action of the first elastic member 220, thereby securing the first connector 101 and the second connector 102 together. When it is necessary to separate the first connector 101 and the second connector 102, the operator can push the locking tongue 210 to slide laterally to unlock the first connector 101 and the second connector 102 axially, allowing the first connector 101 and the second connector 102 to be easily separated, thus facilitating subsequent maintenance of the liquid cooling device.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
