[0050] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0051] The inventors discovered that when installing a water flow switch in a docking pipe, the water flow switch's detector is installed inside the docking pipe. The flow state of the heat exchange medium inside the docking pipe can only be effectively detected when the water flow switch is at the appropriate installation angle. When the water flow switch is installed crookedly or upside down, it can easily affect the normal operation of the hydraulic module. To address the issues of crooked or upside-down installation, manual visual adjustment of the water flow switch's installation angle makes it difficult to accurately adjust the water flow switch's installation position. Furthermore, additional steps are required to verify that the water flow switch is properly installed, resulting in low production efficiency. Therefore, embodiments of the present application provide a water flow switch structure, a hydraulic module, and a heat pump system.

[0052] The water flow switch structure of an embodiment of the present application can be used to regulate the flow state of the heat exchange medium passing through it. As shown in FIG1 , it is a structural schematic diagram of a water flow switch structure 10 of an embodiment of the present application. Among them, the water flow switch structure 10 of the embodiment of the present application can be applied to the hydraulic module and connected with the functional device 20 of the hydraulic module. The hydraulic module includes multiple functional devices 20. As shown in Figure 2, the multiple functional devices 20 of the hydraulic module are all installed in the internal space of the box of the hydraulic module. As shown in Figure 3, at least one functional device 20 is connected to the water flow switch structure 10. The water flow switch structure 10 can be used to connect two functional devices 20, or to connect the functional device 20 with other external structural parts. As shown in Figure 3, the functional device 20 of the hydraulic module includes at least one of a liquid storage tank 21, an expansion tank 22, a heat exchange device 23 and a water pump 24. In Figure 3, a water flow switch structure 10 is provided between the liquid storage tank 21 and the heat exchange device 23. The liquid storage tank 21 and the heat exchange device 23 are connected through the water flow switch structure 10. The water flow switch structure 10 is used to regulate the flow state of the heat exchange medium between the liquid storage tank 21 and the heat exchange device 23.

[0053] FIG4 is a schematic diagram of a water flow switch structure 10 according to an embodiment of the present invention. The water flow switch structure 10 includes a connecting pipe 100 and a switch body 200 .

[0054] The connecting pipe 100 includes a first mounting portion 110 having a first mounting hole 111. The switch body 200 also includes a detector 300, which is disposed within the first mounting hole 111 and is used to detect the flow state of the heat exchange medium in the environment in which it is located. The switch body 200 includes a second mounting portion 210, wherein the first mounting portion 110 and the second mounting portion 210 are correspondingly disposed, and the second mounting portion 210 is detachably mounted to the first mounting portion 110.

[0055] The connecting pipe 100 further includes a first plug-in portion 120 connected to the first mounting portion 110. The first plug-in portion 120 is integrally provided with the first mounting portion 110. As shown in FIG5 , the switch body 200 further includes a second plug-in portion 220 connected to the second mounting portion 210. The second plug-in portion 220 is integrally provided with the second mounting portion 210. The first plug-in portion 120 and the second plug-in portion 220 are correspondingly provided. The first plug-in portion 120 and the second plug-in portion 220 extend toward each other in a preset direction A. The first plug-in portion 120 and the second plug-in portion 220 are plugged and matched to define the position of the second mounting portion 210 relative to the first mounting portion 110. The preset direction A is the opening direction of the first mounting hole 111. This facilitates quick alignment of the first plug-in portion 120 and the second plug-in portion 220, making assembly easy.

[0056] When the first plug-in portion 120 is plugged into the second plug-in portion 220, the relative position of the first mounting portion 110 and the second mounting portion 210 can be positioned, so that the first mounting portion 110 and the second mounting portion 210 will not rotate relative to each other in the circumferential direction of the first mounting hole 111, and thus the structural member connected to the second mounting portion 210 will not rotate relative to the first mounting portion 110 in the circumferential direction of the first mounting hole 111. In this way, when the detection member 300 of the switch body 200 is installed on the second mounting portion 210, the first plug-in portion 120 and the second plug-in portion 220 are plugged into and matched to directly position the position of the detection member 300, and the detection member 300 will not rotate in the circumferential direction of the first mounting hole 111, so that the position of the detection member 300 can be set more conveniently, so that the detection member 300 is in a more sensitive detection position, and the detection member 300 can more accurately detect the flow state of the heat exchange medium in its environment.

[0057] The connecting pipeline 100 also includes a main body 130, which is connected to the first mounting portion 110 and has a main flow channel inside the main body 130 that is connected to the first mounting hole 111. When the heat exchange medium enters the connecting pipeline 100, it mainly passes through the main flow channel of the main body 130. The detection member 300 provided in the first mounting hole 111 also extends into the main flow channel to detect the flow state of the heat exchange medium in the main flow channel. Specifically, the detection member 300 includes a target piece 310, which is provided in the main flow channel of the main body 130 and has a first detection position and a second detection position. When the target piece 310 is in the first detection position, it has the best detection sensitivity, and the target piece 310 has the highest detection accuracy for the flow state of the heat exchange medium in its environment. The other positions of the target piece 310 other than the first detection position are all set to the second detection position. When the target piece 310 is in the second detection position, the target piece 310 has a poor detection accuracy for the flow state of the heat exchange medium in its environment.

[0058] In the embodiment of the present application, the detection member 300 can be pre-designed to be installed in the installation position of the second installation portion 210. When the first installation portion 110 and the second installation portion 210 are installed in alignment, and the first plug-in portion 120 and the second plug-in portion 220 are plugged into each other, the target piece 310 of the detection member 300 extends into the main flow channel of the main pipe 130 and can be directly in the first detection position, thereby effectively improving the detection accuracy of the target piece 310 of the detection member 300 in detecting the flow state of the heat exchange medium in its environment.

[0059] The main channel of the main body 130 has a central axis H that is angled with a predetermined direction A. The target piece 310 of the detection member 300 is located within the main channel of the main body 130. When the surface of the target piece 310 forms a predetermined angle with the central axis H of the main channel, the target piece 310 is in the first detection position. This application does not limit the range of the predetermined angle; the specific range can be selected based on actual needs.

[0060] As shown in FIG4 , the probe 300 further includes a probe body 320 , a target piece 310 being mounted at an end of the probe body 320 , and the probe body 320 being mounted on the second mounting portion 210 . The probe body 320 has a length in a preset direction A, and the probe body 320 is provided with a first mounting hole 111 so that the target piece 310 can be extended into the main flow channel of the main body 130 . Optionally, the preset direction A is perpendicular to the central axis H of the main flow channel, so that the probe 300 extends into the main flow channel of the main body 130 through the first mounting hole 111, facilitating the placement of the target piece 310 in an appropriate position to detect the flow state of the fluid in the main flow channel. When the probe body 320 is rod-shaped, the preset direction A may be the direction of the axial direction of the rod-shaped probe body 320 .

[0061] 4 and 6 , the first plug-in portion 120 has a first alignment edge 1211, which is parallel to the central axis H of the main channel and overlaps with the central axis H of the main channel in a preset direction A. In this way, based on the position of the first alignment edge 1211, the position of the detection member 300 relative to the second plug-in portion 220 is adjusted accordingly, and the position of the detection member 300 relative to the second plug-in portion 220 is limited. When the second plug-in portion 220 is plugged into the first plug-in portion 120, the angle of the target piece 310 of the detection member 300 relative to the central axis H of the main channel can be positioned, thereby improving the positioning accuracy of the detection member 300 and effectively improving the efficiency.

[0062] The first alignment edge 1211 is located at the first plug-in portion 120. When the switch body 200 is installed on the connecting pipe 100, the position of the first alignment edge 1211 can be observed more intuitively, so as to adjust the switch body 200 to move to a suitable angle to dock with the first installation portion 110 of the connecting pipe 100, thereby improving assembly efficiency.

[0063] As shown in Figure 6, the first plug-in portion 120 has a first alignment end surface 121 and a second alignment end surface 122. The second alignment end surface 122 is disposed opposite the first alignment end surface 121. That is, the first plug-in portion 120 extends from the first alignment end surface 121 and terminates at the second alignment end surface 122. The first alignment end surface 121 is disposed at an angle to the circumferential direction S of the first mounting hole 111. The edge of the first alignment end surface 121 facing the main channel forms a first alignment edge 1211. The second alignment end surface 122 is also disposed at an angle to the circumferential direction S of the first mounting hole 111. When the first plug-in portion 120 is plugged into the second plug-in portion 220, the first alignment end face 121 of the first plug-in portion 120 contacts the surface of the second plug-in portion 220, and the second alignment end face 122 of the first plug-in portion 120 also contacts the surface of the second plug-in portion 220. In this way, the relative positions of the first plug-in portion 120 and the second plug-in portion 220 are restricted, preventing the first plug-in portion 120 from moving relative to the second plug-in portion 220 in the circumferential direction S of the first mounting hole 111.

[0064] Among them, the first alignment end face 121 and the second alignment end face 122 can be set at an angle or in parallel. The embodiment of the present application does not limit this, and can be selected according to actual needs. Optionally, in conjunction with Figures 4 and 6, the first alignment end face 121 is parallel to the preset direction A and the central axis H of the main channel, so that the first plug-in portion 120 and the second plug-in portion 220 are more stable in plug-in cooperation and are not prone to sliding. The second alignment end face 122 is parallel to the preset direction A, so that the mutual stopping effect between the first plug-in portion 120 and the second plug-in portion 220 in the circumferential direction of the first mounting hole 111 is more stable. Of course, in some other embodiments, the first alignment end face 121 can also be set at an angle to the preset direction A, and the second alignment end face 122 can also be set at an angle to the preset direction A. The present application does not limit this, and can be selected according to actual needs.

[0065] As shown in FIG6 , the first plug-in portion 120 is arranged around a preset direction A (i.e., along the circumferential direction S of the first mounting hole 111), and correspondingly, the second plug-in portion 220 is arranged around the preset direction A, and the first plug-in portion 120 and the second plug-in portion 220 are plugged and matched to form an annular stopper, which facilitates a tighter plug-in fit between the first plug-in portion 120 and the second plug-in portion 220, and makes the force on the first plug-in portion 120 and the second plug-in portion 220 more uniform in the circumferential direction S of the first mounting hole 111, and the plug-in fit between the first plug-in portion 120 and the second plug-in portion 220 more stable. Furthermore, in the radial direction R of the annular stopper, the width of the annular stopper is equal, that is, the width of the first plug-in portion 120 is equal to the width of the second plug-in portion 220.

[0066] The first mounting portion 110 has at least one first plug-in portion 120, and the second mounting portion 210 has at least one second plug-in portion 220 that plugs into and mates with the first plug-in portion 120. The central angle of each first plug-in portion 120 around a predetermined direction A is α, where α satisfies the following relationship: 270°≤α<360°. The first plug-in portion 120 and the second plug-in portion 220 plug together to form a 360° annular retaining portion. The central angle of the first plug-in portion 120 corresponds to the central angle of the second plug-in portion 220. When the first mounting portion 110 has a first plug-in portion 120 and the second mounting portion 210 has a second plug-in portion 220, α satisfies: 270°≤α<360°, so that the first plug-in portion 120 and the second plug-in portion 220 can better interact with each other and improve the plug-in stability. When α<270°, the area between the first alignment end face 121 and the second alignment end face 122 is larger, and the first plug-in portion 120 and the second plug-in portion 220 are easy to move relative to each other, which is not conducive to the alignment stability of the first plug-in portion 120 and the second plug-in portion 220.

[0067] Optionally, one of the first plug-in portion 120 and the second plug-in portion 220 is a boss and the other is a groove. For example, the first plug-in portion 120 is a groove, and the two groove side walls that are relatively arranged around the preset direction A (i.e., the circumferential direction S of the first mounting hole 111) respectively form a first alignment end face 121 and a second alignment end face 122, and the two groove side walls that are relatively arranged in the radial direction R of the annular limit portion also respectively fit with the second plug-in portion 220, thereby forming a stable plug-in structure.

[0068] Optionally, both the first plug-in portion 120 and the second plug-in portion 220 are bosses, and one of the first plug-in portion 120 and the second plug-in portion 220 has a plug-in groove for the other to be plugged in. For example, the first plug-in portion 120 has a plug-in groove, and the groove side wall surface and the groove bottom wall surface of the plug-in groove are both in contact with the surface of the second plug-in portion 220, wherein the two groove side walls of the plug-in groove relatively arranged around the preset direction A (i.e., the circumferential direction S of the first mounting hole 111) respectively form a first alignment end face 121 and a second alignment end face 122, and the plug-in groove extends to the inner edge of the annular limit portion in the radial direction R of the annular limit portion, or, the plug-in groove extends to the outer edge of the annular limit portion in the radial direction R of the annular limit portion, or, the plug-in groove passes through the annular limit portion in the radial direction R of the annular limit portion.

[0069] Optionally, both the first plug-in portion 120 and the second plug-in portion 220 are bosses, there is one first plug-in portion 120, and there is one second plug-in portion 220, and the second plug-in portion 220 is plugged between the first alignment end face 121 and the second alignment end face 122 of the first plug-in portion 120; or, there are multiple first plug-in portions 120, and the second plug-in portion 220 is plugged between two first plug-in portions 120; or, there are multiple second plug-in portions 220, and the first plug-in portion 120 is plugged between two second plug-in portions 220.

[0070] The above is only an exemplary introduction. The first plug-in portion 120 and the second plug-in portion 220 are plugged together, and their structures are interchangeable, which will not be repeated here.

[0071] As shown in Figure 4, a preset groove 112 is provided on the end face of the first mounting portion 110, and the first plug-in portion 120 is provided on the bottom wall of the first preset groove 112. The second plug-in portion 220 extends into the preset groove 112 and is plugged into and matched with the first plug-in portion 120. In addition, in the preset direction A, the end face of the first mounting portion 110 is in contact with the end face of the second mounting portion 210, thereby further improving the plug-in stability of the first plug-in portion 120 and the second plug-in portion 220.

The probe 300 is mounted on the mounting body 212 and extends into the first mounting hole 111. The sleeve portion 213 is positioned around the mounting body 212 and the first mounting portion 110 to define the relative position of the mounting body 212 and the first mounting portion 110, thereby enhancing the stability of the alignment between the first and second mounting portions 110 and 210.

[0073] Among them, before assembly, the sleeve portion 213 can be movable relative to the second mounting portion 210, and the position of the sleeve portion 213 relative to the second mounting portion 210 is adjusted to expose the second plug-in portion 220, and the second mounting portion 210 is moved close to the first mounting portion 110, so that the first plug-in portion 120 and the second plug-in portion 220 are plugged and aligned, and then the sleeve portion 213 is sleeved on the periphery of the first mounting portion 110 and the second mounting portion 210 to limit the relative position of the first mounting portion 110 relative to the second mounting portion 210, which is convenient for assembly.

[0074] As shown in FIG. 7 , the sleeve portion 213 has an internal thread, and the first mounting portion 110 has an external thread. The sleeve portion 213 is sleeved around the outer periphery of the first mounting portion 110 and is threadedly mounted on the first mounting portion 110 .

[0075] Optionally, the installation body 212 also has external threads, and the sleeve portion 213 is threadedly connected to the installation body 212 and the first installation portion 110 respectively to define the relative positions of the three.

[0076] Optionally, as shown in FIG8 , the mounting body 212 includes a first portion 2121, the first portion 2121 contacts the first mounting portion 110, and the sleeve portion 213 is sleeved around the first portion 2121 and the first mounting portion 110. Specifically, the first portion 2121 includes a first section 2021 and a second section 2022, the first section 2021 contacts the first mounting portion 110, and the second section 2022 is away from the first mounting portion 110 at the first section 2021. One side is connected to the first section 2021, the first section 2021 has a contact surface facing away from the first mounting portion 110, the contact surface is arranged on the periphery of the second section 2022, the sleeve portion 213 is sleeved on the periphery of the first section 2021, the sleeve portion 213 abuts against the abutment surface and contacts the outer peripheral wall surface of the first section, and the sleeve portion 213 is also installed on the first mounting portion 110, thereby limiting the relative positions of the sleeve portion 213, the first part 2121 and the first mounting portion 110.

[0077] As shown in FIG. 8 , the detection member 300 includes a detection body 320 and a limiting protrusion 330 provided on the detection body 320 . In this case, the mounting body 212 may further include a plurality of second portions 2122 and a third portion 2123 . Specifically, the surface of the first part 2121 for contacting the first mounting portion 110 is provided with a mounting groove 212a facing the first mounting hole 111, and the bottom wall of the mounting groove 212a is provided with a second mounting hole; multiple second parts 2122 are arranged around the periphery of the detection body 320, and the second part 2122 has a limiting hole 212b for accommodating the limiting protrusion 330, and multiple second parts 2122 are arranged in the mounting groove 212a and in contact with the bottom wall of the mounting groove 212a; the third part 2123 is provided in the mounting groove 212a, and the third part 2123 is in contact with the multiple second parts 2122, and the third part 2123 has a third mounting hole 212c, one part of the detection body 320 is provided in the second mounting hole, and the other part passes through the third mounting hole 212c and extends to the first mounting hole 111.

[0078] The third portion 2123 is fixedly mounted to the first portion 2121 to confine the plurality of second portions 2122 within the mounting slot 212a, preventing the plurality of second portions 2122 from moving along the length of the detection body 320, which is parallel to the predetermined direction A. Furthermore, the plurality of second portions 2122 are connected to the first portion 2121 to prevent the plurality of second portions 2122 from rotating about the circumferential direction S of the detection body 320. Thus, the first portion 2121, the second portion 2122, and the third portion 2123 cooperate to securely mount the plurality of second portions 2122 to the first portion 2121, thereby fixing the position of the detection member 300 relative to the first portion 2121.

[0079] The second plug-in portion 220 can be connected to at least one of the first portion 2121 and the third portion 2123. For example, the second plug-in portion 220 is provided on the first portion 2121; or, as shown in FIG8 , the second plug-in portion 220 is provided on the third portion 2123. Furthermore, the surface of the first portion 2121 facing the first mounting portion 110 and the surface of the third portion 2123 facing the first mounting portion 110 form a smooth transition.

[0080] Optionally, one of the first portion 2121 and the third portion 2123 has a hook 2124 and the other has a slot 212f, and the third portion 2123 is fixedly mounted to the first portion 2121 by snapping. The above is merely an exemplary description. In other embodiments, other methods may be used to fix the third portion 2123 to the first portion 2121. Any installation method that allows the third portion 2123 to be detachably mounted to the first portion 2121 is applicable to this application.

[0081] Optionally, one of the second portion 2122 and the first portion 2121 has a protrusion and the other has a guide groove 212d, and the protrusion is disposed in the guide groove 212d to prevent the second portion 2122 from circumferentially moving around the detection body 320. When the second portion 2122 has a protrusion or a guide groove 212d, the protrusion or guide groove 212d may be disposed on the same second portion 2122, or, as shown in FIG8 , the protrusion or guide groove 212d may be formed by splicing two adjacent second portions 2122. The above is merely an exemplary description. In other embodiments, other methods may be used to securely mount multiple second portions 2122 to the first portion 2121. Any mounting method that can mount the second portion 2122 to the first portion 2121 to prevent the second portion 2122 from circumferentially moving around the detection body 320 is applicable to the present application.

[0082] Multiple second parts 2122 can be spliced ​​together by plugging. For example, as shown in Figure 8, one of the two adjacent second parts 2122 has a guide column 2125 and the other has a guide hole 212e. The guide column is plugged into the guide hole 212e to splice the two adjacent second parts 2122 for easy assembly.

[0083] The probe 300 may be provided with two limiting protrusions 330, which are disposed on opposite sides of the probe body 320 to improve the installation stability of the probe 300. In this case, the number of second portions 2122 may be two, three, or four. As shown in FIG8 , there are two limiting protrusions 330 and two second portions 2122, which are disposed on opposite sides of the probe body 320. Each second portion 2122 has a limiting hole 212b, one limiting protrusion 330 being inserted into one limiting hole 212b, and the other limiting protrusion 330 being inserted into the other limiting hole 212b.

[0084] An embodiment of the present application also provides a hydraulic module, which includes a box body, multiple functional devices 20 and the water flow switch structure 10 as described above. The multiple functional devices 20 are all arranged in the internal space of the box body. The hydraulic module includes at least one group of water flow switch structures 10, at least one of which is connected to the connecting pipe 100 of the water flow switch structure 10, wherein the connecting pipe 100 is used to conduct the two functional devices 20 connected thereto, or the water flow switch structure 10 is used to conduct the functional device 20 connected thereto with the external structure to form a smooth medium transmission channel. By using the water flow switch structure 10 of the present application to detect the flow state of the heat exchange medium in the medium transmission channel, good detection accuracy can be achieved.

[0085] It can be understood that at the joint between the connecting pipe 100 and the functional device 20, the structure for sealing is achieved by squeezing the seal to produce deformation, and the seal produces a large deformation. Maintaining a large deformation for a long time is likely to crush the sealing ring, which in turn is likely to cause seal failure. The crushed seal needs to be replaced when the pipeline is repaired. If the crushed seal continues to be used, the risk of heat exchange medium leakage is greatly increased.

[0086] The present embodiment further provides a pipeline docking structure 30, through which the connecting pipeline 100 can be connected to the functional components 20 of the hydraulic module. FIG9 is a schematic diagram showing the structure of the pipeline docking structure 30 installed on the functional components 20 according to one embodiment of the present application. When the pipeline docking structure 30 according to the present embodiment is applied to a hydraulic module, the hydraulic module includes multiple functional components 20, at least one of which is connected to one of the docking pipes 301 of the pipeline docking structure 30. As shown in FIG10 , the functional components 20 of the hydraulic module include at least one of a liquid storage tank 21, an expansion tank 22, a heat exchange device 23, and a water pump 24.

[0087] 10 and 11 , the pipe docking structure 30 includes a seal 400 and two butt-jointing pipes 301, each of which has a sub-flow channel 101 therein. As shown in FIG11 , one butt-jointing pipe 301 is mounted on the other butt-jointing pipe 301 to align and connect the two butt-jointing pipes 301. The sub-flow channels 101 of the two butt-jointing pipes 301 are connected to form a guide channel 103. Heat exchange medium flows within the guide channel 103 to be transferred between the structural components connected to the two butt-jointing pipes 301.

[0088] For example, referring again to FIG11 , the water pump 24 includes an inlet pipe 241 and an outlet pipe 242. Two sets of pipe docking structures 30 are connected to the water pump 24. One of the docking pipes 301 in one set of pipe docking structures 30 forms the inlet pipe 241, and the other docking pipe 301 of the same pipe docking structure 30 is in communication with the liquid storage tank 21. One of the docking pipes 301 in the other set of pipe docking structures 30 forms the outlet pipe 242, and the other docking pipe 301 of the same pipe docking structure 30 is in communication with an external water delivery structure. The water pump 24 operates to deliver the heat exchange medium within the liquid storage tank 21 to the external water delivery structure. Optionally, the water pump 24 includes a centrifugal water pump, an axial flow water pump, or the like. The above is merely an exemplary description. In other embodiments, a set of pipe docking structures 30 may be provided at any location where pipe docking is required for the heat exchange medium inlet and outlet of components such as the liquid storage tank 21, the expansion tank 22, and the heat exchange device 23. The specific arrangement may be selected based on actual needs.

[0089] As shown in Figure 12, the two sections of the butt-jointed tubes 301 are butt-jointed and define a sealed cavity 102. The sealed cavity 102 is arranged around the periphery of the guide channel 103 and is spaced apart from the guide channel 103. The seal 400 is arranged in the sealed cavity 102, and the outer surfaces of the seal 400 are respectively in contact with the wall surfaces of the two sections of the butt-jointed tubes 301. In this way, a separate sealed cavity 102 is planned for installing the seal 400. The two sections of the butt-jointed tubes 301 are assembled in place to define the sealed cavity 102. After the two sections of the butt-jointed tubes 301 are assembled in place, they act on the seal 400. The seal 400 is deformed in the sealed cavity 102 and achieves sealing. There is no need to rely on the seal 400 to produce a large deformation to achieve a sealing effect. Compared to related art methods that directly install a seal 400 between two structures and estimate the sealing effect by estimating the deformation of the seal 400, the sealing effect at the pipeline docking structure 30 of the embodiment of the present application is more reliable. The deformation of the seal 400 is small. After disassembly and maintenance, the seal 400 can still be installed in the sealed cavity 102 and the seal 400 can still provide a good sealing effect. In addition, the two sections of the butt joint pipe 301 confine the seal 400 within the sealed cavity 102, which can control the deformation area of ​​the seal 400, thereby preventing the seal 400 from undergoing large deformation and preventing the seal 400 from being crushed and reducing the sealing effect due to being in a deformed state for a long time.

[0090] 12 and 13 , at least one of the two butt-jointing tubes 301 has a sealing groove 104. When the two butt-jointing tubes 301 are separated, a seal 400 can be pre-installed in the sealing groove 104 to initially limit the position of the seal 400. Once the two butt-jointing tubes 301 are brought together and installed in place, the sealing groove 104 contributes to forming the sealed cavity 102. In other words, the sealing groove 104 can be a part of the sealed cavity 102. The provision of the sealing groove 104 limits the position of the seal 400, preventing it from moving freely, facilitating installation, and helping to improve alignment and assembly efficiency.

[0091] As shown in FIG13 , the butt joint tube 301 has a butt joint surface 106, and the sub-channel 101 extends to the butt joint surface 106. The butt joint surfaces 106 of the two butt joint tubes 301 are arranged toward each other, and at least part of the butt joint surfaces 106 of the two butt joint tubes 301 are arranged in contact with each other. Specifically, the butt joint surface 106 has a butt joint area 312, and the butt joint area 312 of the butt joint surface 106 is arranged in contact with the area opposite to it. After disassembly and maintenance, the butt joint surfaces 106 of the two butt joint tubes 301 are brought closer to each other. When the butt joint area 312 of the butt joint surface 106 is in contact with the area opposite to it and the relative positions of the two butt joint tubes 301 are fixed, it means that the two butt joint tubes 301 are assembled in place, and the two butt joint tubes 301 define a sealed cavity 102. The sealing member 400 is placed in the sealed cavity 102 and abutted by the two butt joint tubes 301 to achieve sealing.

[0092] At least one of the two mating surfaces 106 has a groove area 311 , and the groove area 311 and the mating surface 106 opposite thereto define a sealing cavity 102 . The groove area 311 is provided with the sealing groove 104 as described above. Optionally, at least one of the two docking surfaces 106 has both a groove area 311 and a docking area 312, and the groove area 311 is recessed relative to the docking area 312 to form a sealing groove 104. For example, one of the docking surfaces 106 has a groove area 311 and a docking area 312, and the other docking surface 106 has only a docking area 312. The docking areas 312 of the two docking surfaces 106 fit together, and the groove area 311 of one of the docking surfaces 106 and a part of the docking area 312 of the other docking surface 106 are spaced apart and define a sealing cavity 102; or, both of the two docking surfaces 106 have a groove area 311 and a docking area 312, the docking areas 312 of the two docking surfaces 106 fit together, and the groove areas 311 of the two docking surfaces 106 are arranged relative to each other, and the docking areas 312 jointly define a sealing cavity 102.

[0093] Of course, in other embodiments, as shown in FIG14 , one of the mating surfaces 106 may have only a groove area 311, while the other mating surface 106 may have both a groove area 311 and a mating area 312, wherein the edge of the groove area 311 of one mating surface 106 contacts the mating area 312 of the other mating surface 106, and the groove areas 311 of the two mating surfaces 106 jointly define the sealed cavity 102. Alternatively, each mating surface 106 may have only a groove area 311, and the edges of the groove areas 311 of the two mating surfaces 106 contact each other, and the two groove areas 311 jointly define the sealed cavity 102.

[0094] Among them, the docking area 312 is a plane or a convex arc surface. The embodiment of the present application does not limit the surface shape of the docking area 312, and can be selected according to the requirements of the embodiment. Any surface shape that can enable the two docking tubes 301 to be stably connected after docking is applicable to this application.

[0095] As shown in Figures 13 and 14, the docking surface 106 has a docking inner edge 1111, which defines the first opening of the sub-channel 101. After the two sections of the docking tubes 301 are docked, the first openings of the sub-channels 101 of the two sections of the docking tubes 301 are connected to each other to connect the two sections of the sub-channels 101 and form the diversion channel 103.

[0096] Optionally, the groove area 311 extends to the docking inner edge 1111. For example, as shown in Figure 14, when the same docking surface 106 only has the groove area 311, the inner edge of the groove area 311 forms the docking inner edge 1111, and the outer edge of the groove area 311 forms the docking outer edge. The docking inner edge 1111 and the docking outer edge of the docking surface 106 having the groove area 311 are in contact with the other docking surface 106; or, when the same docking surface 106 has the groove area 311 and the docking area 312, the inner edge of the groove area 311 forms the docking inner edge 1111, the outer edge of the groove area 311 is connected to the docking area 312, the outer edge of the docking area 312 forms the docking outer edge, and the docking area 312 is in contact with the other docking surface 106.

[0097] Optionally, the groove area 311 is spaced apart from the abutment inner edge 1111. In this case, the same abutment surface 106 includes the groove area 311 and the abutment area 312. The inner edge of the abutment area 312 forms the abutment inner edge 1111, and the outer edge of the abutment area 312 forms the abutment outer edge. The inner edge of the groove area 311 is spaced apart from the abutment inner edge 1111, and the outer edge of the groove area 311 extends to the abutment outer edge. Alternatively, the inner edge of the groove area 311 is spaced apart from the abutment inner edge 1111, and the outer edge of the groove area 311 is spaced apart from the abutment outer edge.

[0098] Optionally, two sections of butt joint tubes 301 are installed in a sleeve-like manner. Specifically, one of the two sections of butt joint tubes 301 is a first butt joint tube 3011, and the other is a second butt joint tube 302. As shown in FIG15 , the first butt joint tube 3011 has a butt joint groove 301a. The sub-flow channel 101 of the first butt joint tube 3011 extends to the groove bottom wall 301b of the butt joint groove 301a, and the groove bottom wall 301b of the butt joint groove 301a forms the butt joint surface 106 of the first butt joint tube 3011. The end of the second butt joint tube 302 is disposed within the butt joint groove 301a and has an end wall 302a facing the groove bottom wall 301b of the butt joint groove 301a. The sub-flow channel 101 of the second butt joint tube 302 extends to the end wall 302a, and the end wall 302a forms the butt joint surface 106 of the second butt joint tube 302. In this way, the first docking tube 3011 is sleeved on the outer periphery of the second docking tube 302 to facilitate quick alignment and assembly. The end of the second docking tube 302 extends into the docking groove 301a of the first docking tube 3011, and the docking surface 106 of the first docking tube 3011 contacts the docking surface 106 of the second docking tube 302. After fixing the relative positions of the first docking tube 3011 and the second docking tube 302, the sealing cavity 102 is defined, and the first docking tube 3011 and the second docking tube 302 are both in contact with the seal 400 to form a good sealing structure.

[0099] The second butt joint tube 302 has an outer peripheral wall surface, which is connected to the end wall surface 302a of the second butt joint tube 302 and is arranged at an angle. At least one of the groove bottom wall surface 301b of the first butt joint tube 3011, the end wall surface 302a of the second butt joint tube 302, and the outer peripheral wall surface of the second butt joint tube 302 has a sealing groove 104. When the outer peripheral wall surface of the second butt joint tube 302 has a sealing groove 104, the wall surface of the second butt joint tube 302 defining the sealing groove 104 and the groove side wall surface 301c of the butt joint groove 301a jointly define the sealed cavity 102.

[0100] Optionally, the outer peripheral wall surface of the end portion of the second butt joint tube 302 and the groove sidewall surface 301c of the butt joint groove 301a are both threaded surfaces, and the second butt joint tube 302 is threadedly connected to the first butt joint tube 3011 to facilitate assembly. In this case, at least one of the groove bottom wall surface 301b of the first butt joint tube 3011 and the end wall surface 302a of the second butt joint tube 302 is provided with a sealing groove 104; alternatively, the outer peripheral wall surface of the second butt joint tube 302 is provided with a sealing groove 104, and the sealing groove 104 is spaced apart from the threaded surface. Furthermore, in the direction from the end wall surface 302a of the second butt joint tube 302 toward the groove bottom wall surface 301b of the first butt joint tube 3011, the distance from the sealing groove 104 of the second butt joint tube 302 to the butt joint surface 106 is shorter than the distance from the threaded surface to the butt joint surface 106.

[0101] As shown in Figure 15, the sealing cavity 102 is a contoured cavity similar in shape to the sealing member 400, and the two sections of the butt-joint tubes 301 limit the wall surface of the sealing cavity 102 to fit with the wall surface of the sealing member 400. The two sections of the butt-joint tubes 301 are increased to limit the contact area with the sealing member 400, and the position of the sealing member 400 is limited by the sealing cavity 102 to prevent the sealing member 400 from being deformed and partially squeezed out of the sealing cavity 102 under the extrusion of the two butt-joint tubes 301. In this way, effective sealing can be achieved without the seal 400 undergoing a large amount of deformation.

[0102] Among them, the seal 400 is arranged on the periphery of the guide channel 103, the seal 400 has a central axis H, the guide channel 103 has a transition flow section 105 passing through the seal 400, and the flow direction of the fluid passing through the transition flow section 105 is parallel to the direction of the central axis H of the seal 400. Furthermore, the seal 400 and the transition flow section 105 are coaxially arranged. The openings of the sub-flow channels 101 of the two connecting tubes 301 are located in the area where the transition flow section 105 is located. For example, please refer to Figure 12 again. The transition flow section 105 is formed by connecting a portion of the sub-flow channel 101 of one of the connecting tubes 301 and a portion of the sub-flow channel 101 of the other connecting tube 301. At this time, the openings of the sub-flow channels 101 of the two connecting tubes 301 are located in the middle area of ​​the transition flow section 105; or, the entire transition flow section 105 is formed by a portion of the sub-flow channel 101 of one of the connecting tubes 301. At this time, the openings of the sub-flow channels 101 of the two connecting tubes 301 are located at the edge of the transition flow section 105.

[0103] As shown in Figure 15, the seal 400 has multiple sealing flanges 410, and each sealing flange 410 is arranged around the central axis H of the seal 400. When the two sections of the butt-jointing pipe 301 act on the seal 400, each sealing flange 410 is deformed. Compared with the method of using a flat gasket to squeeze the entire plane of the seal 400 to cause the seal 400 to deform, by providing multiple sealing flanges 410, the deformation amount is dispersed, and the deformation amount of a single sealing flange 410 is smaller than the deformation amount of the entire seal 400, thereby improving the aging resistance of the seal 400.

[0104] Optionally, two adjacent sealing flanges 410 are connected; or, as shown in Figure 15, two adjacent sealing flanges 410 are spaced apart, and the seal 400 also includes a sealing surface 420 arranged between the two adjacent sealing flanges 410, and the sealing surface 420 is connected to the surface of the sealing flange 410, and the surface of the sealing flange 410 and the sealing surface 420 are both connected to the docking surface 106 of the docking pipe 301.

[0105] The sealing flange 410 protrudes in the direction of the central axis H of the seal 400, or in a direction perpendicular to the central axis H of the seal 400, so that the sealing flange 410 deforms in the protruding direction to achieve a good seal. Furthermore, a portion of the sealing flange 410 protrudes in one direction, while another portion of the sealing flange 410 protrudes in another direction. Furthermore, multiple sealing flanges 410 are arranged in groups of two, with the two sealing flanges 410 in each group being arranged opposite each other in the direction of the central axis H of the seal 400 and protruding in directions away from each other. The multiple sealing flanges 410 protruding toward the same side are located on the same sealing transition surface. In the protruding direction of the sealing flange 410, the distance from the surface of the sealing flange 410 to the sealing transition surface is the height of the sealing flange 410, and the heights of the multiple sealing flanges 410 are equal. The sealing transition surface may be the plane where the sealing surface 420 as described above is located. The sealing transition surface may be a plane or an arcuate surface. When the sealing transition surface is an arcuate surface, the curvature of the sealing transition surface is smaller than the curvature of the sealing transition surface.

[0106] As shown in FIG15 , when at least one of the mating surface 106 of the first butt joint tube 3011 and the mating surface 106 of the second butt joint tube 302 includes a sealing groove 104, the sealing flange 410 protrudes in the direction of the central axis H of the seal 400, so that the sealing flange 410 deforms in the direction of the central axis H of the seal 400 to achieve a good seal. A sealing surface 420 is provided between two adjacent sealing flanges protruding toward the same side. The maximum distance from the surface of the sealing flange 410 to the sealing surface 420 in the direction of the central axis H of the seal 400 is the height of the sealing flange 410. For example, as shown in FIG15 , the seal 400 has four sealing flanges 410 and two sealing surfaces 420. The four sealing flanges 410 are divided into two groups, each sealing surface 420 connected to two sealing flanges 410 protruding toward the same side. The sealing surfaces 420 are planes perpendicular to the central axis H of the seal 400.

[0107] The seal 400 of the embodiment of the present application is an elastic seal 400, so that the seal 400 can better adapt to the shape of the sealed cavity 102 and fit tightly with the wall of the sealed cavity 102. Optionally, the seal 400 is a silicone seal, a foam seal, a rubber seal, etc.
