[0043] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] The inventor discovered that when the water flow switch is installed in the docking pipe, the detection part of the water flow switch is installed inside the docking pipe. Only when the water flow switch is at a suitable installation angle can the flow state of the heat exchange medium inside the docking pipe be effectively detected. When the water flow switch is installed crookedly or reversely, it is easy to affect the normal operation of the hydraulic module. In order to solve the problem of crooked installation or reverse installation, it is difficult to accurately adjust the installation position of the water flow switch by manually adjusting the installation angle of the water flow switch. At the same time, other processes need to be added to verify whether the water flow switch is installed properly, which has low production efficiency. Therefore, the embodiments of the present application provide a water flow switch structure, a hydraulic module and a heat pump system.

[0045] The water flow switch structure of the embodiment of the present application can be used to regulate the flow state of the heat exchange medium passing through it, such as Figure 1 As shown, it is a schematic diagram of the structure of a water flow switch structure of an embodiment of the present application. Among them, the water flow switch structure of the embodiment of the present application can be applied to a hydraulic module and communicated with the functional components of the hydraulic module. The hydraulic module includes multiple functional components, such as Figure 2 As shown, multiple functional devices of the hydraulic module are installed in the internal space of the hydraulic module box, at least one functional device is connected to the water flow switch structure, and the water flow switch structure can be used to connect two functional devices, or to connect the functional device with other external structural parts, such as Figure 3 As shown, the functional components of the hydraulic module include at least one of a liquid storage tank, an expansion tank, a heat exchange device and a water pump. Figure 3In the embodiment, a water flow switch structure is provided between the liquid storage tank and the heat exchange device, the liquid storage tank and the heat exchange device are connected through the water flow switch structure, and the water flow switch structure is used to regulate the flow state of the heat exchange medium between the liquid storage tank and the heat exchange device.

[0046] The water flow switch structure of the embodiment of the present application can be used to regulate the flow state of the heat exchange medium passing through it, such as Figure 1 , which is a schematic diagram of the structure of a water flow switch structure 10 according to an embodiment of the present application. The water flow switch structure 10 according to the embodiment of the present application can be applied to a hydraulic module and communicated with a functional device 20 of the hydraulic module. The hydraulic module includes a plurality of functional devices 20, such as Figure 2 As shown, the multiple functional components 20 of the hydraulic module are installed in the inner space of the hydraulic module box, such as Figure 3 As shown, at least one functional device 20 is connected to the water flow switch structure 10, and 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 structures, such as Figure 3 As shown, 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. Figure 3 In the figure, 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.

[0047] like Figure 4 FIG. 1 is a schematic diagram of a water flow switch structure 10 according to an embodiment of the present application. The water flow switch structure 10 includes a connecting pipeline 100 and a switch body 200 .

[0048] The connecting pipeline 100 includes a first mounting portion 110, the first mounting portion 110 has a first mounting hole 111, and the switch body 200 also includes a detection member 300, which is arranged in 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 arranged, and the second mounting portion 210 is detachably mounted on the first mounting portion 110.

[0049] The connecting pipeline 100 further includes a first plug-in portion 120 connected to the first mounting portion 110, and the first plug-in portion 120 is integrally arranged with the first mounting portion 110. Figure 5As shown, the switch body 200 also includes a second plug-in portion 220 connected to the second mounting portion 210, the second plug-in portion 220 and the second mounting portion 210 are integrally arranged, and the first plug-in portion 120 and the second plug-in portion 220 are correspondingly arranged, wherein the first plug-in portion 120 and the second plug-in portion 220 extend toward each other in a preset direction A, and the first plug-in portion 120 and the second plug-in portion 220 are plugged together to limit the position of the second mounting portion 210 relative to the first mounting portion 110, and the preset direction A is the opening direction of the first mounting hole 111, so that the first plug-in portion 120 and the second plug-in portion 220 are quickly aligned and easy to assemble.

[0050] When the first plug-in portion 120 and the second plug-in portion 220 are plugged in and matched, the relative positions 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 further, 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 plug-in cooperation of the first plug-in portion 120 and the second plug-in portion 220 can 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.

[0051] 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 connected to the first mounting hole 111 inside the main body 130. 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 arranged 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 arranged 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 detection accuracy of the target piece 310 for the flow state of the heat exchange medium in its environment becomes poor.

[0052] 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 and matched, 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.

[0053] The main flow channel of the main body 130 has a central axis H that is at an angle to the preset direction A. The target piece 310 of the detection member 300 is in the main flow channel of the main body 130. When the plate surface of the target piece 310 is at a preset angle to the central axis H of the main flow channel, the target piece 310 is at the first detection position. The present application does not limit the range of the preset angle, which can be selected according to actual needs.

[0054] like Figure 4 As shown, the detection member 300 also includes a detection body 320, the target piece 310 is installed at the end of the detection body 320, and the detection body 320 is installed on the second installation part 210. Among them, the detection body 320 has a length in the preset direction A, and the detection body 320 is penetrated by the first installation 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 detection member 300 penetrates the first installation hole 111 and extends into the main flow channel of the main body 130, which is convenient for arranging the target piece 310 at a suitable position to detect the flow state of the fluid in the main flow channel. When the detection body 320 is rod-shaped, the preset direction A can be the direction where the axial direction of the rod-shaped detection body 320 is located.

[0055] Combination Figure 4 and Figure 6 The first plug-in portion 120 has a first alignment edge 1211, and the first alignment edge 1211 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.

[0056] 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 mounting portion 110 of the connecting pipe 100, thereby improving assembly efficiency.

[0057] like Figure 6 As shown, the first plug-in portion 120 has a first alignment end face 121 and a second alignment end face 122, and the second alignment end face 122 is arranged opposite to the first alignment end face 121, that is, the first plug-in portion 120 extends from the first alignment end face 121 and ends at the second alignment end face 122. The first alignment end face 121 is arranged at an angle with the circumferential direction S of the first mounting hole 111, and the edge of the first alignment end face 121 facing the main channel forms a first alignment edge 1211, and the second alignment end face 122 is also arranged at an angle with 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 surface 121 of the first plug-in portion 120 contacts the surface of the second plug-in portion 220, and the second alignment end surface 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 limited, 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.

[0058] The first alignment end surface 121 and the second alignment end surface 122 may be arranged at an angle or in parallel, which is not limited in the present embodiment and may be selected according to actual needs. Figure 4 and Figure 6 , the first alignment end surface 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 stably plugged in and not prone to sliding. The second alignment end surface 122 is parallel to the preset direction A, so that the mutual stop 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 surface 121 can also be set at an angle to the preset direction A, and the second alignment end surface 122 can also be set at an angle to the preset direction A. This application does not limit this, and it can be selected according to actual needs.

[0059] like Figure 6 As shown, the first plug-in portion 120 is arranged around the preset direction A (that is, 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 together to form an annular stopper, which facilitates the plug-in and fit of the first plug-in portion 120 and the second plug-in portion 220 to be tighter, and in the circumferential direction S of the first mounting hole 111, the force of the first plug-in portion 120 and the second plug-in portion 220 is more uniform, and the plug-in and fit of the first plug-in portion 120 and the second plug-in portion 220 is more stable. Further, 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.

[0060] 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 plugged with the first plug-in portion 120. The degree of the central angle of each first plug-in portion 120 around the preset direction A is α, and α satisfies: 270°≤α<360°, wherein the first plug-in portion 120 and the second plug-in portion 220 are plugged together to form a 360° annular limiting portion, and the degree of the central angle of the second plug-in portion 220 can be obtained correspondingly according to the degree of the central angle of the first plug-in portion 120. 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.

[0061] 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 a 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.

[0062] 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 wall surfaces of the plug-in groove relatively arranged around a 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 correspondingly, 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.

[0063] Optionally, both the first plug-in portion 120 and the second plug-in portion 220 are bosses, the number of the first plug-in portion 120 is one, the number of the second plug-in portion 220 is one, 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, the number of the first plug-in portion 120 is multiple, and the second plug-in portion 220 is plugged between two first plug-in portions 120; or, the number of the second plug-in portion 220 is multiple, and the first plug-in portion 120 is plugged between two second plug-in portions 220.

[0064] The above is only an exemplary introduction. The first plug-in portion 120 and the second plug-in portion 220 are plug-fitted and their structures are interchangeable, which will not be repeated here.

[0065] like Figure 4 As shown, a preset groove 112 is formed on the end face of the first mounting portion 110, the first plug-in portion 120 is disposed 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, and in the preset direction A, the end face of the first mounting portion 110 is fitted 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.

[0066] like Figure 7 As shown, the second mounting portion 210 includes a mounting body 212 and a sleeve portion 213. The mounting body 212 is arranged corresponding to the first mounting portion 110, and the mounting body 212 is in contact with the first mounting portion 110. The second plug portion 220 is arranged on the surface of the mounting body 212 facing the first mounting portion 110.
