[0002] Currently, water channels can be incorporated into the laser head of laser processing equipment to serve as coolant flow paths, thereby improving the heat dissipation efficiency of the laser head. To prevent coolant leakage when the water cooling system is separated from the external liquid cooling system of the laser head, leak-proof joint structures such as one-way and two-way water-stop joints are typically installed at the inlet and outlet of the water channels. These joint structures include pistons and elastic elements, which allow the pistons to seal the openings of the joint structures when they are not in a mating state, thus preventing leaks.

[0003] However, the piston and elastic element will occupy part of the space in the water flow channel of the joint structure, resulting in a reduction in the water flow cross-sectional area of ​​the joint structure, which in turn leads to an increase in water resistance in the joint structure.

[0063] Currently, laser processing equipment can incorporate water channels within the laser head as coolant flow paths to improve heat dissipation efficiency. To prevent coolant leakage when the water cooling system is separated from the external liquid cooling system of the laser head, leak-proof connectors, such as one-way and two-way water-stop joints, are typically installed at the inlet and outlet of the water channels. These connectors include pistons and elastic elements. When the connectors are not in a mated state, the elastic element drives the piston to seal the opening, thus preventing leakage. However, the piston and elastic element occupy some space in the water flow channel of the connector, reducing the cross-sectional area for water flow and increasing water resistance.

[0064] Based on the above problems, this utility model proposes a connector structure 100' that can reduce water resistance.

[0065] See also Figures 1 to 4 In one embodiment of this utility model, the connector structure 100' includes a first outer shell 10, a piston 20, and a first elastic member 30. The first outer shell 10 has a piston cavity 1211, a flow space, a communication port 1214 connecting the piston cavity 1211 and the flow space, a conduction port 1213 connecting the two ends of the piston cavity 1211, and a second opening 1212. The piston 20 is movably disposed in the piston cavity 1211 and can be close to or away from the second opening 1212, and has a blocking position for blocking the second opening 1212 and a conduction position for opening the second opening 1212. The first elastic member 30 is disposed on the side of the piston 20 away from the second opening 1212 to provide elastic force to the piston 20, so that the piston 20 can move to the blocking position.

[0066] In some embodiments, the flow space is located outside the piston chamber 1211.

[0067] In some embodiments, the first housing 10 includes a first housing 11 and a second housing 12. The first housing 11 is provided with an installation space 111, an installation port 113 and a first opening 112 communicating with the installation space 111 and located at both ends of the first housing 11, and the inner wall of the first housing 11 is provided with a groove 114. The second housing 12 is inserted into the installation space 111 and closes the installation port 113. The second housing 12 is provided with a piston chamber 1211 and a guide port 1213 and a second opening 1212 communicating with the piston chamber 1211. The guide port 1213 and the second opening 1212 are located at both ends of the piston chamber 1211, and the side wall of the second housing 12 is provided with a communication groove 114 and a communication port 1214 communicating with the piston chamber 1211.

[0068] In some embodiments, the first outer shell 10 includes a first housing 11 and a second housing 12, wherein the first housing 11 and the second housing 12 are integrally formed into the first outer shell 10, which can be achieved through manufacturing processes known to those skilled in the art. The remaining structure is similar to... Figures 1 to 4 Similar to other embodiments, the flow space may at least surround a portion of the piston cavity 1211. In some embodiments, the flow space is an annular space. In some embodiments, there are at least two flow spaces, which are disposed opposite to each other on both sides of the piston cavity 1211.

[0069] Specifically, the connector structure 100' has a first outer shell 10 as the main body for installation. The first outer shell 10 includes a first housing 11 and a second housing 12, which are fitted together to form a double-layered shell structure. The first housing 11 has an installation space 111 that extends through both ends. One end of the installation space 111 is opened as an installation port 113 for the second housing 12 to enter and exit the installation space 111. The other end of the installation space 111 is opened as a first opening 112 for the flow of fluids such as water and gas into and out of the first housing 11. The second housing 12 is inserted into the mounting space 111 through the mounting port 113, such that at least a portion of the structure of the second housing 12 is disposed within the mounting space 111. The second housing 12 can be entirely located within the mounting space 111, or a portion of its structure can be located outside the mounting space 111. The second housing 12 is provided with a piston chamber 1211 extending through both ends. One end of the piston chamber 1211, adjacent to the first opening 112, serves as a guide port 1213, positioned opposite to the first opening 112. The other end of the piston chamber 1211... The end opening serves as the second opening 1212, used to supply fluids such as water and gas into or out of the piston chamber 1211. With this configuration, when the connector structure 100' is applied, one of the first opening 112 and the second opening 1212 serves as a fluid inlet, and the other serves as a fluid outlet. Taking the first opening 112 as the fluid inlet and the second opening 1212 as the fluid outlet as an example, fluid enters the piston chamber 1211 from the first opening 112, and the fluid in the piston chamber 1211 can flow out from the second opening 1212.

[0070] In this embodiment, the connector structure 100' is a stop connector. The piston 20 is movably disposed in the piston chamber 1211 and abuts against the first elastic member 30. The first elastic member 30 is disposed on the side of the piston 20 facing away from the second opening 1212. When no connection is needed, the piston 20 is held in the blocking position by the action of the first elastic member 30 to block the second opening 1212. When water needs to pass through, the piston 20 is pressed into the connecting position to connect the second opening 1212 with the piston chamber 1211. At this time, the first elastic member 30 is in a compressed state. Optionally, the end of the first elastic member 30 away from the piston 20 can abut against the inner wall of the first housing 11 where the first opening 112 is provided, or the second housing 12 can have a bottom wall opposite to the second opening 1212, with a connecting port 1213, so that the first elastic member 30 abuts against the bottom wall of the second housing 12.

[0071] In this embodiment, the inner wall of the first housing 11 is provided with a groove 114, and the side wall of the second housing 12 is provided with a connecting port 1214 connecting the groove 114 and the piston chamber 1211. This arrangement allows the piston chamber 1211 and the groove 114 to connect, serving as a flow channel space for fluid flow inside the connector structure 100'. Furthermore, the piston 20, located within the piston chamber 1211, does not occupy the space formed by the groove 114. This arrangement expands the internal flow channel space through the groove 114, increasing the flow channel space and thus increasing the cross-sectional area for water passage in the connector structure 100', thereby reducing water resistance.

[0072] Optionally, in this embodiment, the cross-sectional dimension of the piston 20 can be set to be smaller than the cross-sectional dimension of the piston cavity 1211; that is, the piston 20 and at least part of the inner wall of the second housing 12 are spaced apart to form a water passage gap. Alternatively, in the following embodiment, a clearance hole 24 is provided at the end of the piston 20 facing away from the second opening 1212, and a flow port 25 connecting the clearance hole 24 and the communication port 1214 is provided on the side wall of the piston 20, so that when the piston 20 is in the conducting position, the first opening 112 and the second opening 1212 can communicate with each other.

[0073] Optionally, the first housing 11 may have one, two, three, or more installation spaces 111, each of which may house a second housing 12 and is equipped with a piston 20 and a first elastic element 30, among other structures. When two or more second housings 12 are provided, two or more flow channel spaces are formed in the joint structure 100', which can meet the requirements for setting up multiple flow channels and reduce the use of the joint structure 100'. Furthermore, at least two second housings 12 can be interconnected or integrally formed, allowing multiple second housings 12 to be assembled and disassembled simultaneously, improving assembly convenience.

[0074] Optionally, the groove 114 surrounds the second housing 12.

[0075] Please see Figure 3 In one embodiment, the side wall of the second housing 12 is provided with a limiting port 1215, and the piston 20 is provided with a limiting protrusion 23 located at the communication port 1214. When the piston 20 moves to the conducting position, the limiting protrusion 23 abuts against the side of the communication port 1214 near the first opening 112. This arrangement can prevent the piston 20 from rotating or deviating during movement by utilizing the cooperation between the limiting protrusion 23 and the limiting port 1215, ensuring that the communication port 1214 and the groove 114 maintain corresponding positions. At the same time, when the piston 20 is in the conducting position, the limiting protrusion 23 limits the movement of the piston 20, making the piston 20 stably located in the conducting position, ensuring that the flow channel space inside the connector structure 100' is in an ideal conducting state, which is beneficial to reducing water resistance.

[0076] Please see Figure 3 In one embodiment, the piston 20 is provided with a clearance hole 24 at one end facing the first opening 112, and the side wall of the piston 20 is provided with a flow port 25 that connects the clearance hole 24 and the communication port 1214.

[0077] In this embodiment, the outer wall of the piston 20 can be made to fit against the inner wall of the second housing 12 to limit the piston 20, ensure the stability of the piston 20 during movement, avoid the piston 20 from deviating, and ensure that the second opening 1212 can be sealed when the piston 20 is in the sealing position.

[0078] In this embodiment, a clearance hole 24 is provided at one end of the piston 20 opposite to the second opening 1212, and a flow port 25 communicating with the clearance hole 24 is provided on the side wall of the piston 20. The flow port 25 and the communication port 1214 provided on the side wall of the second housing 12 are at least partially opposite to each other, so that the flow port 25 and the communication port 1214 are interconnected, thereby allowing the clearance hole 24 to communicate with the groove 114 on the inner wall of the first housing 11. With this configuration, when the piston 20 is in the conducting state, the portion of the piston cavity 1211 located between the piston 20 and the second opening 1212 is connected to the groove 114. The groove 114 is connected to the clearance hole 24 through the communication port 1214 and the flow port 25. The portion of the piston cavity 1211 located between the piston 20 and the first opening 112 is connected to the clearance hole 24, so that the portion of the piston cavity 1211 located on the side of the second opening 1212 is interconnected with the portion of the space located on the side of the first opening 112, allowing fluid to flow through the internal space of the connector structure 100'.

[0079] In some embodiments, the piston 20 is provided with a limiting protrusion 23, which can make the limiting protrusion 23 and the flow port 25 arranged along the circumference of the piston 20; optionally, the piston 20 has two first sidewalls arranged opposite to each other along a first direction and two second sidewalls arranged opposite to each other along a second direction, with the limiting protrusion 23 provided on the first sidewall and the flow port 25 provided on the second sidewall.

[0080] Please see Figure 3 In one embodiment, the piston 20 has a clearance hole 24 at one end facing the first opening 112, and a portion of the structure of the first elastic member 30 is disposed in the clearance hole 24. This arrangement allows the clearance hole 24 to limit the first elastic member 30, thereby preventing the first elastic member 30 from shifting and ensuring that the first elastic member 30 provides a stable elastic force to the piston 20.

[0081] Please see Figures 1 to 4 In one embodiment, the second housing 12 is provided with a limiting part 123, which is located outside the piston chamber 1211 and abuts against the end of the first housing 11 that is provided with an installation port 113.

[0082] In this embodiment, the second housing 12 includes a plug-in portion 121 and a limiting portion 123 disposed at one end of the plug-in portion 121. The plug-in portion 121 is inserted into the mounting space 111 of the first housing 11 and has a piston chamber 1211. The limiting portion 123 is located outside the plug-in portion 121. The limiting portion 123 can be arranged around the circumference of the plug-in portion 121, or it can be arranged only in a local area outside the plug-in portion 121. The limiting portion 123 abuts against the end face of the first housing 11. This arrangement can limit the distance of the plug-in portion 121 inserted into the mounting space 111, thereby improving the relative positional stability of the first housing 11 and the second housing 12. In addition, the limiting portion 123 can be arranged around the circumference of the plug-in portion 121, which can increase the contact area between the first housing 11 and the second housing 12, and is beneficial to improving the sealing strength between the first housing 11 and the second housing 12.

[0083] Please see Figure 2 and Figure 3 In one embodiment, the connector structure 100' further includes a first sealing ring 40, which is disposed between the first housing 11 and the second housing 12 and surrounds the second housing 12 to seal the gap between the first housing 11 and the second housing 12.

[0084] For ease of explanation, the portion of the second housing 12 inserted into the mounting space 111 is defined as the insertion portion 121, which has a piston chamber 1211. In this embodiment, the first sealing ring 40 can be sandwiched between the inner side wall of the first housing 11 and the outer side wall of the insertion portion 121. Alternatively, in some embodiments, the second housing 12 is provided with a limiting portion 123 located at one end of the insertion portion 121 and surrounding the insertion portion 121. The limiting portion 123 abuts against the end face of the first housing 11, and the first sealing ring 40 can be sandwiched between the limiting portion 123 and the end face of the first housing 11.

[0085] The first sealing ring 40 helps to improve the sealing strength between the first housing 11 and the second housing 12, thereby reducing the risk of fluid leakage from the connection point of the first housing 11 and the second housing 12.

[0086] Please see Figure 2 and Figure 3 In one embodiment, a limiting part 123 is provided on the outer side of the second housing 12. The limiting part 123 is located outside the piston cavity 1211 and is arranged around the piston cavity 1211 in a circumferential manner. The limiting part 123 abuts against the end of the first housing 11 that is provided with the mounting port 113. The end face of the first housing 11 is provided with an annular notch 115. The notch 115 is arranged around the mounting port 113 in a circumferential manner. The first sealing ring 40 is provided in the notch 115 and abuts against the limiting part 123.

[0087] In this embodiment, the second housing 12 includes a plug-in portion 121 and a limiting portion 123 disposed at one end of the plug-in portion 121. The plug-in portion 121 is inserted into the mounting space 111 of the first housing 11 and is provided with a piston chamber 1211. The limiting portion 123 is located outside the plug-in portion 121 and is arranged around the circumference of the plug-in portion 121 and abuts against the end face of the first housing 11. This can improve the relative positional stability of the first housing 11 and the second housing 12.

The docking portion 122 has a first flow channel 1221 that communicates with the piston chamber 1211.

[0093] In this embodiment, the second housing 12 includes a plug-in portion 121 and a docking portion 122 connected to each other. The plug-in portion 121 is inserted into the mounting space 111 of the first housing 11 and is provided with a piston cavity 1211 and a communication port 1214, a guide port 1213 and a second opening 1212 communicating with the piston cavity 1211. The docking portion 122 is connected to the end of the plug-in portion 121 where the piston cavity 1211 is provided and protrudes from the first housing 11. The docking portion 122 is provided with a first flow channel 1221 communicating with the second opening 1212. In practical applications, this configuration uses the connector structure 100' as a male connector, with a female connector paired with it. The female connector has a second flow channel 2013 and a mounting hole 2016 that are interconnected, and a push rod 202 that is movably disposed in the second flow channel 2013 and the mounting hole 2016. When the male connector and the female connector are mated, the mating part 122 is inserted into the mounting hole 2016 of the female connector, and the push rod 202 passes through the first flow channel 1221 to be inserted into the piston cavity 1211 and abut against the piston 20, thereby pushing the piston 20 to the through position. Through the insertion and engagement of the mating part 122 and the mounting hole 2016, the connection strength and stability of the male and female connectors can be improved.

[0094] Please see Figure 1 In one embodiment, the joint structure 100' further includes a second sealing ring 50, which is sleeved on the outside of the mating portion 122.

[0095] In this embodiment, the connector structure 100' is provided with a second sealing ring 50 sleeved on the outside of the mating part 122. When the connector structure 100' is mated with the female connector as a male connector, the second sealing ring 50 is sandwiched between the mating part 122 and the side wall of the female connector forming the mounting hole 2016 to improve the sealing strength and reduce the risk of fluid leakage.

[0096] Optionally, a limiting groove is provided on the outer wall of the mating part 122, and the second sealing ring 50 can be placed in the limiting groove. The limiting groove can limit the second sealing ring 50 to prevent it from being misaligned, thus ensuring the sealing effect. In addition, the second sealing ring 50 is partially protruding from the limiting groove to ensure that the second sealing ring 50 can abut against the inner wall of the female connector.

[0097] Please see Figure 2 and Figure 3In one embodiment, the piston 20 includes a first part 21 and a second part 22 connected to each other. The first part 21 is connected to the first elastic member 30. The second part 22 is located on the side of the first part 21 away from the first elastic member 30. The cross-sectional dimension of the second part 22 is smaller than that of the first part 21. The joint structure 100' also includes a third sealing ring 60 sleeved on the second part 22. When the piston 20 is in the blocking position, the second part 22 passes through the second opening 1212. The outer wall of the second part 22 fits against the inner wall of the second housing 12 that surrounds the second opening 1212. The third sealing ring 60 is sandwiched between the outer wall of the second part 22 and the inner wall of the second housing 12.

[0098] In this embodiment, the piston 20 has a first portion 21 and a second portion 22 connected along the arrangement direction from the first opening 112 to the second opening 1212. The first elastic member 30 abuts against the first portion 21. When the piston 20 is in the blocking position, the second portion 22 can be inserted into the second opening 1212 to block the second opening 1212. This arrangement can ensure the positional stability of the piston 20 blocking the second opening 1212 and avoid misalignment.

[0099] Furthermore, a third sealing ring 60 is fitted on the outside of the second part 22. When the second part 22 passes through the second opening 1212, the third sealing ring 60 is sandwiched between the outer wall of the second part 22 and the inner wall of the second housing 12 to improve the sealing effect when the piston 20 blocks the second opening 1212 and reduce the risk of fluid leakage.

[0100] Please see Figure 2 and Figure 3 In one embodiment, the connector structure 100' further includes a fourth sealing ring 70, which is disposed on the end face of the first housing 11 where the first opening 112 is provided, and is arranged around the first opening 112.

[0101] In this embodiment, the connector structure 100' is also provided with a fourth sealing ring 70 installed on the first housing 11. The fourth sealing ring 70 is provided on the end face of the first housing 11 where the first opening 112 is provided. With this arrangement, when the connector structure 100' is connected to other devices at the first opening 112 end, the fourth sealing ring 70 can be sandwiched between the first housing 11 and the connected device, thereby improving the sealing effect.

[0102] Please see Figure 1 In one embodiment, the first housing 11 is provided with a first connecting part 116, which is located at one end where the first opening 112 is located, and is used to connect with other devices to fix the connector structure 100' to other devices.

[0103] In this embodiment, by providing a first connecting portion 116 in the first housing 11, the connector structure 100' can be connected to other devices through the first connecting portion 116, allowing the connector structure 100' to be installed and fixed to other devices, thus enabling the connector structure 100' to have assembly compatibility. Optionally, the first connecting portion 116 is provided with a locking hole for inserting bolts or other locking accessories, or the first connecting portion 116 can be configured as a snap-fit, pin, or other structure, which is not limited here.

[0104] Please see Figures 5 to 10 This application also proposes a connector assembly 1000, including a first connector 100 and a second connector 200, wherein the first connector 100 is configured as a connector structure 100' as in any of the foregoing embodiments.

[0105] The second connector 200 includes a second housing 201, a push rod 202, and a second elastic element 203. The second housing 201 has a second flow channel 2013 and a third opening 2014 communicating with the second flow channel 2013. The cross-sectional dimension of the third opening 2014 is smaller than the cross-sectional dimension of the second flow channel 2013. The push rod 202 includes a rod head 2021 disposed in the second flow channel 2013 and a rod body 2022 passing through the third opening 2014. The cross-sectional dimension of the rod body 2022 is smaller than the cross-sectional dimension of the third opening 2014 and the second opening 1212 disposed in the first connector 100. The push rod 202 is movably disposed so that the rod head 2021 can approach or move away from the third opening 2014, and has a clearance position for opening the third opening 2014 and a flow-blocking position for blocking the third opening 2014.

[0106] The second elastic element 203 is located on the side of the rod head 2021 facing away from the third opening 2014 to provide elastic force to the push rod 202, enabling the push rod 202 to move to the cut-off position. When the first connector 100 and the second connector 200 are connected, the push rod 202 passes through the first opening 112 and abuts against the piston 20, so that the push rod 202 moves to the avoidance position and the piston 20 moves to the conduction position, so that the second flow channel 2013 communicates with the piston chamber 1211.

[0107] In this embodiment, the connector assembly 1000 is a bidirectional stop valve. The connector assembly 1000 includes a detachably connected first connector 100 and a second connector 200. The structure of the first connector 100 is the same as the connector structure 100' in any of the aforementioned embodiments, and will not be described again here. The second connector 200 includes a second housing 201 as the mounting body. The second housing 201 is provided with a second flow channel 2013 and a third opening 2014 and a fourth opening 2015 communicating with the second flow channel 2013. One of the third opening 2014 and the fourth opening 2015 serves as a fluid inlet, and the other serves as a fluid outlet, so that fluids such as water and gas can enter and exit the second flow channel 2013. Optionally, the fourth opening 2015 can be provided on the top wall opposite to the third opening 2014, or it can be provided on the side wall of the second housing 201, which is not limited here.

[0108] The push rod 202 is movably disposed relative to the second housing 201 and includes a rod head 2021 and a rod body 2022 connected to each other. The rod head 2021 is located in the second flow channel 2013, and the rod body 2022 passes through the third opening 2014 and extends outward from the third opening 2014. The direction of movement of the push rod 202 is the same as the axial direction of the push rod 202, allowing the rod head 2021 to approach and move away from the third opening 2014. When the push rod 202 is in the intercepting position, the rod head 2021 blocks the third opening 2014. When the push rod 202 is in the avoidance position, the rod head 2021 and the third opening 2014 are spaced apart. In this embodiment, the cross-sectional dimension of the rod body 2022 is smaller than the cross-sectional dimension of the third opening 2014, so that the third opening 2014 can communicate with the second flow channel 2013 when the push rod 202 is in the avoidance position. A second elastic element 203 is provided on the side of the rod head 2021 facing away from the rod body 2022. The two ends of the second elastic element 203 abut against the top wall of the rod head 2021 and the second outer shell 201, respectively. The second elastic element 203 can apply an elastic force to the top rod 202 so that the top rod 202 can move from the avoidance position to the interception position and remain in the interception position.

[0109] In practical applications, when the first connector 100 and the second connector 200 are connected, and the second opening 1212 and the third opening 2014 are positioned opposite each other, the rod 2022 of the push rod 202 is inserted into the second opening 1212 to abut against the piston 20. At this time, the piston 20 and the push rod 202 interact, and the piston 20 is pushed by the push rod 202 to move from the blocking position to the conducting position, so that the second opening 1212 is connected to the piston chamber 1211; at the same time, the push rod 202 is pushed by the piston 20 to move from the flow-blocking position to the clearance position, so that the third opening 2014 is connected to the second flow channel 2013. With this arrangement, the second flow channel 2013 can be connected to the piston chamber 1211, so that the fluid can flow between the first connector 100 and the second connector 200.

[0110] When the first connector 100 and the second connector 200 are separated, the piston 20 in the first connector 100 moves to the blocking position under the action of the first elastic member 30 to block the second opening 1212 and prevent fluid from flowing out of the second opening 1212; the push rod 202 in the second connector 200 moves to the intercepting position under the action of the second elastic member 203 so that the rod head 2021 blocks the third opening 2014 and prevents fluid from flowing out of the third opening 2014. In this way, bidirectional water stop can be achieved between the first connector 100 and the second connector 200.

[0111] Since this connector assembly 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0112] Optionally, the first housing 11 of the first connector 100 may be provided with one, two, three or more installation spaces 111. Each installation space 111 may be equipped with a second housing 12 and correspondingly provided with a piston 20 and a first elastic element 30. When there are two or more second housings 12, two or more flow channel spaces are formed in the connector structure 100'. At this time, the corresponding second connector 200 is provided with two or more second flow channels 2013. Each second flow channel 2013 is correspondingly provided with a second elastic element 203 and a push rod 202. Each second flow channel 2013 is connected to one flow channel space in the first connector 100, thereby forming multiple guiding paths in the connector assembly 1000, which can meet the usage requirements of setting multiple flow channels.

[0113] Please see Figure 6 , Figure 8 as well as Figure 9 In one embodiment, the second outer shell 201 includes a shell body 2011 and a partition 2012 protruding from the shell body 2011. The partition 2012 has a third opening 2014. The shell body 2011 has a second flow channel 2013 and a mounting hole 2016 located on the side of the partition 2012 away from the second flow channel 2013. When the first connector 100 and the second connector 200 are connected, a portion of the first outer shell 10 is inserted into the mounting hole 2016.

[0114] In this embodiment, the second outer shell 201 includes a shell body 2011 and a partition 2012. The shell body 2011 is provided with a second flow channel 2013 and a mounting hole 2016 located on both sides of the partition 2012. The partition 2012 is provided with a third opening 2014. The mounting hole 2016 and the second flow channel 2013 are connected through the third opening 2014. The rod 2022 of the top rod 202 passes through the third opening 2014 from the second flow channel 2013 and is inserted into the mounting hole 2016. The first outer shell 10 of the first connector 100 is provided with a mating portion 122. The mating portion 122 has a first flow channel 1221 communicating with the piston chamber 1211. When the first connector 100 and the second connector 200 are mated, the mating portion 122 is inserted into the mounting hole 2016 of the second connector 200, and the push rod 202 passes through the first flow channel 1221 to be inserted into the piston chamber 1211 and abut against the piston 20, thereby pushing the piston 20 to the through position. Through the insertion and cooperation of the mating portion 122 and the mounting hole 2016, the connection strength and stability between the first connector 100 and the second connector 200 can be improved.

[0115] See also Figure 8 and Figure 9 In one embodiment, the second outer shell 201 has a top wall disposed opposite to the third opening 2014 and a side wall disposed around the second flow channel 2013. The side wall of the second outer shell 201 is provided with a fourth opening 2015, which communicates with the second flow channel 2013.

[0116] In this embodiment, the fourth opening 2015 is disposed on the side wall of the second housing 201. When the top rod 202 is in the avoidance position, the fourth opening 2015 is located between the rod head 2021 and the third opening 2014, thereby avoiding the rod head 2021 from blocking the fourth opening 2015 when the second connector 200 needs to be connected, thus ensuring the connection effect.

[0117] See also Figures 8 to 10 Optionally, the shell body 2011 includes a main shell 2011a and a cover 2011b. The main shell 2011a is provided with a second flow channel 2013 and a third opening 2014. A fourth opening 2015 is provided on the side wall of the main shell 2011a. An opening is provided at one end of the main shell 2011a opposite to the third opening 2014, and the cover 2011b covers this end opening. The top rod 202 and the second elastic member 203 can be disassembled and assembled by removing the cover 2011b, and the second flow channel 2013 can also be cleaned. Optionally, the second connector 200 also includes a sixth sealing ring 205 sandwiched between the main shell 2011a and the cover 2011b to improve the sealing strength between the main shell 2011a and the cover 2011b and reduce the risk of fluid leakage.

[0118] Please see Figure 6In one embodiment, the second connector 200 further includes a fifth sealing ring 204, which is sleeved on the outside of the rod head 2021. When the top rod 202 is in the cut-off position, the fifth sealing ring 204 is sandwiched between the inner surfaces of the rod head 2021 and the second outer shell 201.

[0119] In this embodiment, a fifth sealing ring 204 is fitted on the outside of the rod head 2021. When the top rod 202 is in the flow-blocking position and the rod head 2021 blocks the third opening 2014, the fifth sealing ring 204 is sandwiched between the outer wall of the rod head 2021 and the inner surface of the second outer shell 201 to improve the sealing effect when blocking the third opening 2014 and reduce the risk of fluid leakage.

[0120] Please see Figures 8 to 10 In one embodiment, a limiting hole 2023 is provided at the end of the rod head 2021 facing away from the rod body 2022, and a portion of the second elastic element 203 is located in the limiting hole 2023. This arrangement allows the limiting hole 2023 to limit the second elastic element 203, thereby preventing the second elastic element 203 from deviating and ensuring that the second elastic element 203 provides a stable elastic force to the top rod 202.

[0121] In one embodiment, the second housing 201 is provided with a second connecting portion, allowing the second connector 200 to be connected to other devices via the second connecting portion.

A water channel for coolant flow is provided in the laser head 2, and this water channel is connected to an external liquid cooling system. The liquid cooling system introduces coolant at a lower temperature into the water channel. The coolant flows along the liquid cooling channel, exchanges heat with the laser head, and then flows back to the liquid cooling system, thus carrying away the heat from the laser head and achieving heat dissipation and cooling of the laser head. The cooling system can also cool the coolant.

[0124] In this embodiment, the water path of the laser head 2 is connected to the connector structure 100' at both the inlet and outlet ends. Two water passages can be provided in the connector structure 100' to communicate with the inlet and outlet ends respectively, or the connector structure 100' can be connected to both the inlet and outlet ends separately. In practical applications, the second connector 200 of the connector assembly 1000 is connected to the liquid cooling system, thereby preventing leakage in both the water path and the liquid cooling system when the laser head 2 is disconnected from the liquid cooling system.
