Description

Technical Field

[0001] This utility model relates to the field of liquid cooling system technology, and in particular to a connection end, a fluid connector and a liquid cooling system. Background Technology

[0002] Fluid connectors typically consist of two connection ends that can be mated together to connect pipelines. Existing connection ends include a valve seat, a valve core, and a valve cover. The valve cover is fixedly connected to the valve seat, and a chamber for the valve core to rotate is formed between the valve cover and the valve seat. The rotation of the valve core opens and closes the flow channel within the connection end.

[0003] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: the valve plate needs to be reserved in the connection end, which results in a long axial length of the connection end, which is not conducive to the application in small space scenarios. Utility Model Content

[0004] One objective of this invention is to provide a connection end that can effectively solve the problem of a large axial dimension of the connection end. Another objective is to provide a fluid connector including the above-mentioned connection end. Yet another objective is to provide a liquid cooling system including the above-mentioned fluid connector.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A connection end includes: a first valve body and a first valve cover. The first valve body has a first flow channel. The first valve cover includes a first outer shell and a first valve fixed to the first outer shell. The first outer shell is rotatably sleeved on the outer periphery of the first valve body. The first valve is located at one end of the first valve body and has a first channel. When the first outer shell rotates in a circumferential direction to a first position, the first channel is completely offset from the first flow channel to close the first flow channel. When the first outer shell rotates in a circumferential direction to a second position, the first channel communicates with the first flow channel to open the first flow channel.

[0007] In some technical solutions, the first valve is integrally formed on the first housing, and the first valve and the first housing form a barrel-shaped structure covering the first valve body.

[0008] In some technical solutions, the first valve body is provided with a first stop portion that can extend and retract along the axis, and the first valve is provided with a first locking groove. When the first housing is in the first position, the first stop portion extends out and engages with the first locking groove to limit the rotation of the first housing relative to the first valve body.

[0009] In some technical solutions, the first valve body is provided with a first pushing part extending along the axial direction, the first valve is provided with a first arc-shaped groove and a second arc-shaped groove distributed along the circumferential direction, the first pushing part passes through the first arc-shaped groove along the axial direction, and the first locking groove is located at one end in the second arc-shaped groove.

[0010] In some technical solutions, the connection end further includes a first connection cap, the first valve is located at one end of the first housing, the first connection cap is connected to the end of the first housing away from the first valve, and the first connection cap is used to axially limit the first valve cover to the first valve body.

[0011] In some technical solutions, the first valve body includes a first section and a second section distributed along the axial direction. The outer diameter of the first section is larger than the outer diameter of the second section. A stepped surface is formed between the first section and the second section. At least a portion of the structure of the first housing is sleeved on the outer periphery of the first section. The first connecting cap is sleeved on the outer periphery of the second section. The outer periphery of the first connecting cap is detachably connected to the first housing, and one end of the first connecting cap abuts against the stepped surface.

[0012] In some technical solutions, the first valve body is provided with at least two first flow channels, and the first valve is provided with the same number of first channels as the first flow channels. When the first outer shell rotates in the circumferential direction to the first position, each first channel is completely offset from each first flow channel. When the first outer shell rotates in the circumferential direction to the second position, each first channel is connected to each first flow channel in a one-to-one correspondence.

[0013] A fluid connector includes a mating end and a connecting end as described in any of the preceding claims, wherein the mating end and the connecting end are detachably connected.

[0014] In some technical solutions, the docking end includes a second valve body and a second valve cover. The second valve body is provided with a second flow channel. The second valve cover includes a second outer shell and a second valve disposed within the second outer shell. The second valve is provided with a second channel. The second outer shell is rotatably fitted onto the outer periphery of the second valve body. The first valve cover and the second valve cover are detachably connected.

[0015] In some technical solutions, the mating end further includes a second connecting cap, the second valve is located inside the second housing, the second connecting cap is connected to the end of the second housing away from the second valve, and the second connecting cap is used to axially limit the second valve cover to the second valve body.

[0016] In some technical solutions, one end of the second housing is fitted onto the outer periphery of the first housing. The outer periphery of the first housing is provided with radially protruding interlocking protrusions, and the sidewall of the second housing is provided with interlocking slots. The interlocking protrusions and the interlocking slots can be inserted into each other so that the first housing and the second housing can rotate synchronously to connect or close the first flow channel and the second flow channel.

[0017] In some technical solutions, the first valve body has a receiving groove on its circumferential surface, and the first outer shell has a locking hole and a locking ball movably connected to the locking hole. The locking hole has a first opening facing the first valve body and a second opening away from the first valve body. The locking ball can be partially located in the receiving groove along the first opening. When the first outer shell rotates relative to the first valve body to open the first flow channel, the locking hole can drive the locking ball to move out of the receiving groove and contact the circumferential surface of the first valve body, so that the locking ball partially extends out along the second opening. The inner wall of the second outer shell, which is sleeved on one end of the first outer shell, has a connecting groove extending in the circumferential direction. The connecting groove is used to accommodate the portion of the locking ball extending out of the second opening, so as to define the axial position of the first outer shell and the second outer shell. When the first outer shell rotates in the opposite direction relative to the first valve body to close the first flow channel, the locking hole can drive the locking ball to move along the circumferential surface of the first valve body until a portion of the locking ball structure retracts into the receiving groove, so that the first outer shell and the second outer shell can be separated from each other in the axial direction.

[0018] In some technical solutions, the first outer shell is provided with a plurality of lock holes distributed along the circumferential direction and a plurality of lock beads corresponding one-to-one with the lock holes.

[0019] In some technical solutions, the second valve body is provided with a locking member that can extend and retract radially, and the second outer shell is provided with a locking hole.

[0020] In some technical solutions, the second housing is provided with a pressing part, which is used to push the locking member back when pressure is applied.

[0021] In some technical solutions, a rubber sleeve is provided around the outer periphery of the second housing, and the pressing part is disposed on the rubber sleeve. The pressing part is used to reset under the elastic force of the rubber sleeve when the pressure is lost.

[0022] In some technical solutions, a first pipe connector is detachably connected to the end of the first valve body away from the first valve, and the first pipe connector is connected to the first flow channel. A second pipe connector is detachably connected to the end of the second valve body away from the second valve, and the second pipe connector is connected to the second flow channel.

[0023] A liquid cooling system comprising the fluid connector described in any of the preceding claims.

[0024] Compared with existing technologies, the above technical solution has at least the following advantages:

[0025] The connection end provided by this utility model has a first outer shell that is sleeved on the outer periphery of the valve body, allowing the user to directly rotate it to open and close the first valve. Compared with the prior art, which requires a rotatable valve core between the valve cover and the valve body to open and close the flow channel, this invention eliminates the need for a valve core, effectively reducing the axial length of the connection end. Furthermore, it eliminates the need for an operating part and a through linkage mechanism outside the valve cover, effectively reducing the complexity of the connection end.

[0026] The fluid connector provided by this utility model has corresponding advantages because it includes the above-mentioned connection end.

[0053] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0054] Please refer to Figures 1 to 12 .

[0055] This utility model provides a connecting end 100 that can be used in conjunction with a mating end 200. The mating end 200 may have the same structure as or be partially different from the connecting end 100. Figures 1 to 3As shown, the connecting end 100 includes a first valve body 110 and a first valve cover 120. The first valve body 110 is provided with a first flow channel 111. The first valve cover 120 includes a first outer shell 121 and a first valve 122 fixed to the first outer shell 121. The first valve 122 can be integrally formed on the first outer shell 121. The first valve 122 and the first outer shell 121 form a barrel-shaped structure covering the first valve body 110. During assembly, the first valve cover 120 can be directly placed on the first valve body 110, so the assembly is relatively convenient. The first valve 122 can be provided with a first channel 1221. The number of first channels 1221 is... The number of first channels 111 is the same as that of the first valve body 110. For example, when the first valve body 110 has one first channel 111, the first valve 122 also has one first channel 1221; when the first valve body 110 has two first channels 111, the first valve 122 also has two first channels 1221; when the first valve body 110 has more first channels 111, the first valve 122 also has more first channels 1221. The first channels 111 should be eccentrically set relative to the axis of the first valve body 110, and the first channels 1221 should also be eccentrically set relative to the axis of the first valve 122. The first outer shell 121 is rotatably fitted around the outer periphery of the first valve body 110. The outer peripheral surface of the first outer shell 121 is exposed, allowing the user to directly rotate the first outer shell 121. The first valve 122 is located at one end of the first valve body 110. The function of the first valve 122 is mainly to open and close the first flow channel 111. The position of the first valve 122 in the circumferential direction can be achieved by rotating the first outer shell 121. When the first outer shell 121 is in the first position in the circumferential direction, for example, when the first channel 1221 is completely offset from the first flow channel 111, the first valve 122 closes the first flow channel 111. When the first outer shell 121 is in the second position in the circumferential direction, for example, when the planar projection of the first channel 1221 relative to the first flow channel 111 in the axial direction at least partially overlaps, the first valve 122 opens the first flow channel 111. Since the first outer shell 121 is sleeved on the outer periphery of the valve body, it can be directly rotated by the user to open and close the first valve 122. Compared with the prior art, which requires a rotatable valve core between the valve cover and the valve body to open and close the flow channel, the valve core is eliminated, which can effectively reduce the axial length of the connection end 100. Moreover, there is no need to set an operating part outside the valve cover and a linkage mechanism passing through the valve cover, which can effectively reduce the complexity of the structure of the connection end 100. Therefore, it can reduce costs and improve the convenience of maintenance.

[0056] In some embodiments, to ensure that the first valve 122 can stably close the first flow channel 111 on the first valve body 110 before the connecting end 100 and the mating end 200 are connected, so as to effectively prevent liquid leakage in the first flow channel 111, the first valve body 110 is provided with a first stop portion 115 that can extend and retract axially, and the first valve 122 is provided with a first locking groove 1224. The first stop portion 115 can be a spring pin, for example, a cavity can be provided on the first valve body 110 facing the first valve 122, and the spring pin can be disposed in the cavity. The first locking groove 1224 can be provided on the first valve 122. When the first outer shell 121 is in the first position, the first stop 115 extends out and engages with the first locking groove 1224 to limit the rotation of the first outer shell 121 relative to the first valve body 110. For example, the head of the spring pin is engaged in the through hole. When it is necessary to unlock the locking relationship between the first valve 122 and the first valve body 110 in the circumferential direction, the first stop 115 can be pushed back into the first valve body 110 by the structure on the docking end 200. At this time, the first outer shell 121 can rotate relative to the axis of the first valve body 110, thereby realizing the opening of the first flow channel 111.

[0057] In some embodiments, the first valve body 110 is provided with a first pushing part 114 extending axially, and the first valve 122 is provided with a first arc-shaped groove 1222 and a second arc-shaped groove 1223 distributed circumferentially. The first arc-shaped groove 1222 and the second arc-shaped groove 1223 have the same length in the circumferential direction. The first pushing part 114 passes through the first arc-shaped groove 1222 axially. When the first valve cover 120 rotates relative to the first valve body 110, the first arc-shaped groove 1222 can avoid the first pushing part 114. The first locking groove 1224 is located at one end of the second arc-shaped groove 1223, i.e., the first valve cover 122. When 0 is in the first position, the first stop part 115 is engaged with the first locking groove 1224. When the docking end 200 is docked with the connecting end 100 along the axial direction, the pushing part on the docking end 200 will be inserted into the first locking groove 1224 to push the first stop part 115 back into the first valve body 110. At the same time, the pushing part on the docking end 200 will be further inserted into the first valve body 110 to realize the connection between the two valve bodies, the docking end 200 and the connecting end 100. At this time, the position of the two valve bodies in the circumferential direction can be restricted. Then, the first outer shell 121 can be rotated to realize the purpose of opening the first flow channel 111 of the first valve 122.

[0058] In some embodiments, to limit the axial position of the first valve cover 120 relative to the first valve body 110, the connecting end 100 further includes a first connecting cap 130. The first valve 122 is located at one end of the first housing 121, and the first connecting cap 130 is connected to the end of the first housing 121 away from the first valve 122. The first connecting cap 130 is used to axially limit the first valve cover 120 to the first valve body 110 to prevent axial movement of the first valve cover 120. For example, after the first valve cover 120 is fitted onto the first valve body 110, the first connecting cap 130 is then connected. The first connecting cap 130 and the first valve 122 can clamp the first valve body 110 axially. After the first housing 121 and the first connecting cap 130 are connected, they can rotate synchronously relative to the first valve body 110.

[0059] In some embodiments, the first valve body 110 includes a first segment 1101 and a second segment 1102 distributed axially. The outer diameter of the first segment 1101 is larger than the outer diameter of the second segment 1102. The first valve 122 is located at one end of the first segment 1101 away from the second segment 1102. A stepped surface 1103 is formed between the first segment 1101 and the second segment 1102. At least a portion of the structure of the first housing 121 is fitted onto the outer periphery of the first segment 1101. For example, a portion of the structure of the first housing 121 is fitted onto the outer periphery of the first segment 1101, and another portion is located on the outer periphery of the second segment 1102. In this case, an annular cavity is formed between the first housing 121 and the second segment 1102. A first connecting cap 130 is fitted onto the outer periphery of the second segment 1102, i.e., the first connecting cap 130 is an annular structure. The outer periphery of the first connecting cap 130 is detachably connected to the first housing 121, and one end of the first connecting cap 130 abuts against the stepped surface 1103. The first connecting cap 130 can be connected to the first housing 121 by means of threaded connection or snap-fit. For example, an external thread can be provided on the outer periphery of the first connecting cap 130, and an internal thread corresponding to the second section 1102 in the first housing 121 can be provided to cooperate with the external thread. Furthermore, a flange can be provided on the outer periphery of the end of the first connecting cap 130 away from the first valve 122. When the first connecting cap 130 is connected to the first housing 121, the flange contacts the end of the first housing 121 away from the first valve 122, which can limit the length of the first connecting cap 130 screwed into the first housing 121.

[0060] This utility model embodiment also provides a fluid connector, such as... Figures 7 to 12As shown, it includes a docking end 200 and a connecting end 100 as described above. The docking end 200 and the connecting end 100 are detachably connected. The docking end 200 may have the same structure as the connecting end 100 or a different structure. For example, for a docking end 200 with a different structure, the docking end 200 includes a valve body, a valve cover, and a valve core. The valve cover is fixedly connected to the valve body, and the valve core is located in the movable cavity between the valve cover and the valve core. The first pushing part 114 on the connecting end 100 can pass through the valve cover on the docking end 200 to connect with the valve core. By rotating the first outer shell 121, the movement of the valve core inside the docking end 200 can be realized.

[0061] In some embodiments, the mating end 200 may include the same structure as the connecting end 100, for example... Figures 4 to 7 As shown, the docking end 200 includes a second valve body 210 and a second valve cover 220. The second valve body 210 has a second flow channel 211 inside. The second valve cover 220 includes a second outer shell 221 and a second valve 222 disposed inside the second outer shell 221. A second channel 2214 can be provided on the second valve 222. When the second channel 2214 is connected to the second flow channel 211, the docking end 200 is opened; when the second channel 2214 and the second flow channel 211 are completely offset from each other, the docking end 200 is closed. The second outer shell 221 is rotatably fitted around the outer periphery of the second valve body 210. The structure of the docking end 200, which is identical to that of the connecting end 100, includes at least the second outer shell 221 being able to rotate relative to the second valve body 210 without the need for a valve core. Furthermore, the second valve body 210 on the docking end 200 is provided with a second pushing part 213 and an axially retractable second stop part 215. The second valve 222 is provided with a first movable groove and a second movable groove distributed along the circumferential direction. The first movable groove and the second movable groove are arc-shaped grooves. The second pushing part 213 can extend from the first movable groove. The second valve 222 can rotate circumferentially relative to the second valve body 210 under the action of the first movable groove. The second stop part 215 can be engaged with a second locking groove 1224 provided at one end of the second movable groove. The first pushing part 114 can push the second stop part 215 back into the second valve body 210, and the second pushing part 213 can push the first stop part 115 back into the second valve body 210. The first valve cover 120 and the second valve cover 220 are detachably connected. For example, when it is necessary to connect the docking end 200 and the connecting end 100, the first valve cover 120 and the second valve cover 220 can be connected so that the first valve cover 120 and the second valve cover 220 can rotate synchronously, thereby realizing the opening or closing of the first flow channel 111 and the second flow channel 211.

[0062] In some embodiments, the mating end 200 further includes a second connecting cap 250. The second valve 222 is located within the second housing 221, and the second connecting cap 250 is connected to the end of the second housing 221 away from the second valve 222. The second connecting cap 250 is used to axially limit the second valve cover 220 onto the second valve body 210. During assembly, as... Figure 5 As shown, the second outer shell 221 can be first placed over the second valve body 210 from right to left, and then the second connecting cap 250 can be connected to the left end of the second outer shell 221 from left to right, so that the second connecting cap 250 abuts against the second valve body 210. A stepped surface can be provided on the outer periphery of the second valve body 210, and an external thread can be provided on the outer periphery of the second connecting cap 250. An internal thread can be provided on the inner side of the end of the second outer shell 221 away from the second valve 222. The second connecting cap 250 can be fitted onto the outer periphery of the second valve body 210. By threading the second connecting cap to the second outer shell 221, so that the second connecting cap 250 abuts against the stepped surface, the axial positioning of the second outer shell 221 can be achieved.

[0063] In some embodiments, one end of the second outer shell 221 is sleeved around the outer periphery of the first outer shell 121 to ensure the alignment of the first outer shell 121 and the second outer shell 221. The outer periphery of the first outer shell 121 has radially protruding interlocking protrusions 1212, and the sidewall of the second outer shell 221 has interlocking slots 2212. When the mating end 200 and the connecting end 100 are axially connected, the interlocking protrusions 1212 and the interlocking slots 2212 can be interlocked to allow the first outer shell 121 and the second outer shell 221 to rotate synchronously, thereby connecting or closing the first flow channel 111 and the second flow channel 211. After the first outer shell 121 and the second outer shell 221 are interlocked, either the first outer shell 121 or the second outer shell 221 can be rotated to synchronously rotate the first valve 122 and the second valve 222, making operation convenient.

[0064] In some embodiments, in order to improve the stability of the docking end 200 and the connecting end 100 after docking, the first valve body 110 is provided with a receiving groove 112 on its circumferential surface, and the first housing 121 is provided with a locking hole 1211 and a locking ball 113 movably connected to the locking hole 1211. The locking hole 1211 has a first opening facing the first valve body 110 and a second opening away from the first valve body 110. The diameter of the first opening is larger than the diameter of the second opening, and the diameter of the second opening is smaller than the diameter of the locking ball 113. When the connecting end 100 and the docking end 200 are not inserted, the locking ball 113 can be partially located in the receiving groove 112 along the first opening. When the first housing 121 rotates relative to the first valve body 110 to open the first flow channel 111, the locking hole 1211 can drive the locking ball 113 to move out of the receiving groove 112 and contact the circumferential surface of the first valve body 110, so that the locking ball 113 can be partially extended along the second opening. A connecting groove 2213 extending circumferentially is formed on the inner wall of the second outer shell 221, which is fitted onto one end of the first outer shell 121. The cross-section of the connecting groove 2213 can be trapezoidal or arc-shaped. When the second outer shell 221 is fitted onto the first outer shell 121, and the first outer shell 121 and the second outer shell 221 are rotated, part of the locking ball 113 will protrude from the second opening of the lock hole 1211. At this time, the connecting groove 2213 can accommodate the part of the locking ball 113 that protrudes from the second opening, thereby limiting the axial position of the first outer shell 121 and the second outer shell 221. Since the locking ball 113 has the characteristic of being able to roll, it can reduce the friction between the first valve body 110 and the second outer shell 221 during the locking process, which is beneficial to reduce wear and extend service life. When the first outer shell 121 rotates in the opposite direction relative to the first valve body 110 to close the first flow channel 111, the locking hole 1211 can drive the locking ball 113 to move along the circumferential surface of the first valve body 110 until a part of the structure of the locking ball 113 retracts into the receiving groove 112, so that the first outer shell 121 and the second outer shell 221 can be separated from each other in the axial direction.

[0065] In some embodiments, the first housing 121 is provided with a plurality of circumferentially distributed locking holes 1211 and a plurality of locking beads 113 corresponding one-to-one with the locking holes 1211, wherein the locking beads are preferably evenly distributed along the circumferential direction to ensure the balance of force. The axial engagement of the connecting end 100 and the mating end 200 is achieved by using a plurality of locking beads 113, which can effectively improve the connection stability of the two. Furthermore, to facilitate the smooth entry of the locking beads 113 into the receiving groove 112 when the first housing 121 and the second housing 221 are mated, a guide slope 2215 can be provided on the end face of the second housing 221 facing the first housing 121. When the guide slope on the second housing 221 contacts the locking beads 113, as the second housing 221 moves axially toward the first housing 121, the guide slope 2215 on the second housing 221 will push the locking beads 113 into the receiving groove 112 until the connection is complete. After the groove 2213 aligns with the lock hole 1211, the first outer shell 121 and the second outer shell 221 can be rotated synchronously. At this time, under the pushing action of the inner wall of the lock hole 1211 on the lock ball 113, the lock ball 113 will be pushed out from the receiving groove 112. During the process of being pushed out, the lock ball 113 gradually emerges from the lock hole 1211 until the lock ball 113 enters the connecting groove 2213 and the outer peripheral surface of the first valve body 110, and then the axial engagement of the first outer shell 121 and the second outer shell 221 can be achieved. In addition, to facilitate the removal of the locking ball 113 from the receiving groove 112, a guide slope 1121 can be provided on one side of the receiving groove 112. When the first flow channel 111 is opened, the first outer shell 121 is rotated, and the locking ball 113 will move out of the receiving groove 112 from the guide slope 1121. When the first flow channel 111 is closed, the first outer shell 121 is rotated in the opposite direction, and the locking ball 113 will enter the receiving groove 112 from the guide slope 1121.

[0066] In some embodiments, the second valve body 210 is provided with a radially retractable locking member 212. The locking member 212 may be a spring pin. For example, a receiving cavity 214 for accommodating the spring pin may be provided on the second valve body 210. The head of the locking member 212 can extend or retract from the receiving cavity 214. The second housing 221 is provided with a locking hole 2211. When the second housing 221 is rotated to the position where the locking member 212 corresponds to the locking hole 2211, the locking member 212 can be engaged in the locking hole 2211, at which time the first flow channel 111 and the second flow channel 211 are connected. When the locking member 212 retracts into the second valve body 210, the second housing 221 can rotate relative to the second valve body 210. The locking element 212 can fix the positions of the first outer shell 121 and the second outer shell 221 in the circumferential direction after the first flow channel 111 and the second flow channel 211 are connected, so as to prevent the first outer shell 121 and the second outer shell 221 from rotating arbitrarily after the fluid connector is connected, thereby effectively ensuring the stability of the connection state.

[0067] In some embodiments, to facilitate control of the locking member 212 retracting into the second valve body 210, the second housing 221 is provided with a pressing part 231, which is used to push the locking member 212 back when pressure is applied. The pressing part 231 can be a push rod, which can compress the locking member 212 into the second valve body 210 through the locking hole 2211; when the push rod is removed from the locking hole 2211, the head of the locking member 212 will engage in the locking hole 2211 to limit the circumferential rotation of the second housing relative to the second valve body 210.

[0068] In some embodiments, a rubber sleeve 230 is fitted around the outer periphery of the second outer shell 221. An axially extending concave-convex limiting structure can be provided between the inner wall of the rubber sleeve 230 and the outer wall of the second outer shell 221. For example, a limiting groove can be provided on the inner wall of the rubber sleeve 230, and a limiting protrusion can be provided on the outer wall of the second outer shell 221. The limiting protrusion and the limiting groove can restrict the circumferential rotation of the rubber sleeve 230 relative to the second outer shell 221. A pressing part 231 is provided on the rubber sleeve 230. For example, a push rod can be provided on the inner side of the rubber sleeve 230. The pressing part 231 is used to reset under the elastic force of the rubber sleeve 230 when pressure is lost. In addition, to facilitate pressing the pressing part 231 on the rubber sleeve 230, a conical groove can be provided on the outer periphery of the second housing 221. When the pressing part 231 is squeezed, the rubber sleeve 230 will deform toward the conical groove. When the pressing position on the rubber sleeve 230 is released, the pressing part 231 will rebound outward so that the locking member 212 can extend and engage with the locking hole 2211.

[0069] In some embodiments, a first pipe connector 140 is detachably connected to one end of the first valve body 110 away from the first valve 122. The first pipe connector 140 may be a pagoda connector. The first pipe connector 140 communicates with the first flow channel 111. A second pipe connector 240 is detachably connected to one end of the second valve body 210 away from the second valve 222. The second pipe connector 240 communicates with the second flow channel 211. The second pipe connector 240 may also be a pagoda connector. By detachably connecting the first pipe connector 140 and the second pipe connector 240, maintenance is facilitated, and it is also easy to replace other types of pipe connectors, thereby improving the adaptability of the fluid connector.

[0070] In some embodiments, to improve the sealing performance of the fluid connector, such as Figure 12As shown, a first sealing ring 1116 is provided at the end of the first valve body 110 on the connecting end 100 facing the first valve 122. A first sealing groove can be provided on the end face of the first valve body 110 facing the first valve 122. The first sealing groove surrounds the first flow channel 111, and the first sealing ring 116 is placed in the first sealing groove. The first valve 122 contacts the first sealing ring 116, which can seal the first valve 122 and the first valve body 110. A second sealing ring 216 is provided at the end of the second valve body 210 on the docking end 200 facing the second valve 222. A second sealing groove can be provided on the end face of the second valve body 210 facing the second valve 222. The second sealing groove surrounds the second flow channel 211, and the second sealing ring 216... The second valve 222 is placed within the second sealing ring, and the second valve 222 contacts the second sealing ring 216, thus sealing the space between the second valve 222 and the second valve body 210. Furthermore, a third sealing ring 223 is provided between the first valve 122 and the second valve 222. The third sealing ring 223 can be located on the end face of the first valve 122 facing the second valve 222, or it can be located on the end face of the second valve 222 facing the first valve 122. For example, a third sealing groove can be provided on the end face of the second valve 222, surrounding the second channel 2214. The third sealing ring 223 is placed within the third sealing groove, and when the first valve 122 contacts the third sealing ring 223, a seal is formed between the first valve 122 and the second valve 222. Additionally, sealing rings are also provided between the first pipe connector 140 and the first valve body 110, and between the second pipe connector 240 and the second valve body 210, to improve the sealing performance of the fluid connector.
