In this way, a multi-way valve can be used to replace a three-way valve and a four-way valve at the same time, thereby improving the integration of the multi-way valve and expanding the adaptability of the multi-way valve. Applying the multi-way valve to a thermal management system and an integrated module can effectively improve the integration of the thermal management system and the integrated module, and reduce the control difficulty and cost of the thermal management system and the integrated module.

The first-layer flow channel is provided with the regulating communication port and at least one switching communication port, and the second-layer flow channel is provided with the first communication port, the second communication port, and at least one switching communication port. This allows the valve core to be provided with the first communication port, the second communication port, the regulating communication port, and the switching communication port, and facilitates the use of the valve core to control the flow direction of the external medium, enabling the multi-way valve to simultaneously have a switching mode and a proportional adjustment mode, thereby improving the integration of the multi-way valve.

[0015] Optionally, the inner wall of the valve body is provided with a groove for accommodating the sealing member. Placing the sealing member in the groove not only ensures a sealed connection between the valve core and the valve body, but also reduces the difficulty of securing the sealing member and ensures the quality of securing the sealing member, thereby improving the sealing effect of the sealing member and ensuring the working performance of the multi-way valve.

[0016] Optionally, the at least five valve ports are provided on the same side wall of the valve body, and the side wall is arranged parallel to the rotation axis of the valve core, so as to facilitate communication between the valve ports and the first communication port, the second communication port, the adjustment communication port, and the switching communication port, while also reducing the difficulty of molding the multiple valve ports.

Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0049] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs.

[0050] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0051] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components.

[0052] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0053] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0054] The term "plurality" used in this application refers to two or more (including two).

[0055] Valves are used in thermal management systems to switch the connection between different circuits in the thermal management system according to demand, so that the thermal management system can meet the heating or cooling needs of the entire vehicle for the motor, battery or passenger compartment, ensuring the vehicle's comfort, safety and range.

[0056] However, the applicant has noticed that in order to achieve the connection relationship between different circuits, multiple valves are usually required. However, the coordination of multiple valves will cause the thermal management system to occupy a larger space and have a lower degree of integration, thereby increasing the cost and control difficulty of the thermal management system.

[0057] In order to solve the above problems, the embodiment of the present application provides a multi-way valve 1000, which specifically provides at least five valve ports 110 on the valve body 100, and the valve core 200 is rotatably provided on the valve body 100, and a first communication port 211, a second communication port 212, an adjustment communication port 213 and a switching communication port 214 are provided on the outer peripheral wall of the valve core 200, and a first switching flow channel 240 and at least one second switching flow channel 250 are provided inside the valve core 200, and the first communication port 211 and the second communication port 212 are both provided as The first switching flow channel 240 is respectively connected to the regulating connecting port 213, and the first connecting port 211 and the second connecting port 212 can be respectively connected to the corresponding valve port 110, and each second switching flow channel 250 is set to connect at least two switching connecting ports 214. In this way, the multi-way valve 1000 can have a switching mode and a proportional adjustment mode, so that the multi-way valve 1000 of the present application can replace a three-way valve and a four-way valve at the same time, improve the integration of the multi-way valve 1000, and expand the adaptability of the multi-way valve 1000.

[0058] The multi-way valve 1000 according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0059] 1 to 6 , a multi-way valve 1000 according to an embodiment of the present application includes a valve body 100 and a valve core 200 .

[0060] As shown in Figures 1, 2, and 3, the valve body 100 is provided with at least five valve ports 110. This means that the valve body 100 is provided with five or more valve ports 110. The valve ports 110 are used to achieve communication between the inside and outside of the multi-way valve 1000, thereby ensuring that external media can flow into the interior of the multi-way valve 1000 through the valve ports 110, and that external media that have flowed into the interior of the multi-way valve 1000 can flow out through the valve ports 110, thereby achieving the transportation of the external media.

[0061] When different valve ports 110 are connected, switching between multiple modes can be achieved.

[0062] In some embodiments, the valve port 110 is connected to an external pipeline, such as a water pump, a motor cooling line, a battery heating line and cooling line, a cabin heating line, etc. This facilitates the use of the valve port 110 to discharge external media into the external pipeline or to transport external media to the multi-way valve 1000 through the external pipeline, thereby facilitating the use of the multi-way valve 1000 to control the flow direction of the external media.

[0063] It should be noted that the external medium mentioned here can be water, refrigerant or other liquids.

[0064] The valve core 200 is rotatably provided on the valve body 100. As shown in Figures 5, 7 and 9, the outer peripheral wall of the valve core 200 is provided with a first connecting port 211, a second connecting port 212, an adjusting connecting port 213 and a switching connecting port 214. A first switching flow channel 240 and at least one second switching flow channel 250 are provided inside the valve core 200. The first connecting port 211 is connected to the adjusting connecting port 213 through the first switching flow channel 240, and the second connecting port 212 is connected to the adjusting connecting port 213 through the first switching flow channel 240. Each second switching flow channel 250 is used to connect at least two switching connecting ports 214.

[0065] Among them, the valve core 200 is provided with a first switching flow channel 240 and at least one second switching flow channel 250, which means that the valve core 200 can be provided with a second switching flow channel 250 or multiple second switching flow channels 250; the first communication port 211 is connected to the regulating communication port 213 through the first switching flow channel 240, and the second communication port 212 is connected to the regulating communication port 213 through the first switching flow channel 240, which means that the external medium flowing through the first communication port 211 and the second communication port 212 can flow to the regulating communication port 213 through the first switching flow channel 240, and the external medium flowing through the regulating communication port 213 can flow to the regulating communication port 213 through the first switching flow channel 240. It can also flow to the first connecting port 211 and the second connecting port 212 through the first switching flow channel 240 to achieve communication between the first connecting port 211 and the second connecting port 212 and the regulating connecting port 213 respectively; each second switching flow channel 250 is used to connect at least two switching connecting ports 214, which means that each second switching flow channel 250 can connect two switching connecting ports 214, or can connect more than two switching connecting ports 214 to achieve mutual communication between at least two switching connecting ports 214, so that the external medium flowing through multiple switching connecting ports 214 can flow to each other through the second switching flow channel 250.

[0066] In summary, the first switching flow channel 240 is used to achieve mutual communication between the regulating communication port 213 and the first communication port 211 and to achieve mutual communication between the regulating communication port 213 and the second communication port 212 , and the second switching flow channel 250 is used to achieve mutual communication between at least two switching communication ports 214 .

[0067] It should be noted that the term "connected" herein refers to the ability for external media to flow between the two. For example, when the regulating communication port 213 is connected to the first communication port 211 via the first switching channel 240, external media flowing through the regulating communication port 213 can flow to the first communication port 211 via the first switching channel 240. Similarly, external media flowing through the first communication port 211 can also flow to the regulating communication port 213 via the first switching channel 240, thereby ensuring the flow of external media and ensuring the performance of the thermal management system 3000.

[0068] In some examples, since the first switching flow channel 240 is used to achieve mutual communication between the regulating communication port 213 and the first communication port 211 and to achieve mutual communication between the regulating communication port 213 and the second communication port 212, when the external medium enters the valve core 200 through the regulating communication port 213, the external medium can flow to the first communication port 211 and the second communication port 212 at the same time through the first switching flow channel 240. When the first communication port 211 and the second communication port 212 are connected to the corresponding valve port 110, the external medium can be discharged through the corresponding valve port 110, so as to control the flow direction and flow path of the external medium, thereby ensuring the working performance of the multi-way valve 1000.

[0069] Accordingly, since the first switching flow channel 240 is used to achieve mutual communication between the regulating communication port 213 and the first communication port 211 and to achieve mutual communication between the regulating communication port 213 and the second communication port 212, when the external medium enters the valve core 200 through the first communication port 211 and the second communication port 212, the external medium can flow to the regulating communication port 213 through the first switching flow channel 240. When the regulating communication port 213 is connected to the corresponding valve port 110, the external medium can be discharged through the valve port 110, so as to control the flow direction and flow path of the external medium.

[0070] At the same time, since each second switching flow channel 250 is used to connect at least two switching communication ports 214, when the external medium enters the valve core 200 through one of the switching communication ports 214, the external medium can flow to the other switching communication ports 214 through the second switching flow channel 250. When the other switching communication ports 214 are connected to the corresponding valve port 110, the external medium can be discharged through the valve port 110, so as to control the flow direction and flow path of the external medium.

[0071] The multi-way valve 1000 has a proportional adjustment mode. In the proportional adjustment mode, one of the valve ports 110 is connected to the adjustment communication port 213, and the first communication port 211 and the second communication port 212 are respectively connected to the corresponding valve port 110. When the valve core 200 rotates, the communication area between the valve port 110 and the first communication port 211 and the second communication port 212 changes. Here, when the multi-way valve 1000 is in the proportional adjustment mode, the first communication port 211 and the second communication port 212 are respectively connected to the corresponding valve port 110, and one of the valve ports 110 is connected to the adjustment communication port 213. This ensures that external media can enter the valve core 200 through at least two valve ports 110 or ensure that external media in the valve core 200 can be discharged through at least two valve ports 110. At the same time, when the valve core 200 rotates, the communication area between the valve port 110 and the first communication port 211 and the second communication port 212 changes, achieving proportional adjustment. In this way, the multi-way valve 1000 of the present application can have a proportional adjustment function.

[0072] In some examples, when the external medium enters the valve core 200 through one of the valve ports 110, since one of the valve ports 110 is connected to the regulating communication port 213, the external medium can enter the valve core 200 through the regulating communication port 213 respectively. Since the first communication port 211 and the second communication port 212 are both connected to the regulating communication port 213 through the first switching flow channel 240, the external medium entering the valve core 200 through the regulating communication port 213 can flow along the guide path of the first switching flow channel 240 to the first communication port 211 and the second communication port 212. Since the first communication port 211 and the second communication port 212 are respectively connected to the corresponding valve ports 110, the external medium can be discharged from the corresponding valve ports 110 of the first communication port 211 and the second communication port 212, so as to achieve the purpose of controlling the flow of the external medium using the multi-way valve 1000 and realize proportional regulation.

[0073] Correspondingly, since the first communicating port 211 and the second communicating port 212 are respectively connected to the corresponding valve ports 110, the external medium can also enter the valve core 200 from the corresponding valve ports 110 of the first communicating port 211 and the second communicating port 212 respectively, and the external medium entering the valve core 200 can flow to the regulating communicating port 213 along the guide path of the first switching flow channel 240. Since one of the valve ports 110 is connected to the regulating communicating port 213, the external medium located in the valve core 200 can be discharged from one of the valve ports 110 connected to the regulating communicating port 213, so as to achieve the purpose of controlling the flow of the external medium by using the multi-way valve 1000 and realize proportional regulation.

[0074] It should be noted that, when the valve core 200 rotates, the communication areas between the first communication port 211 and the second communication port 212 and the corresponding valve port 110 can be changed, thereby achieving the purpose of proportional regulation.

[0075] The valve core 200 rotates to connect two different valve ports 110 via the second switching channel 250. In other words, when the valve core 200 rotates relative to the valve body 100, the second switching channel 250 can be controlled to connect different valve ports 110, thereby achieving switching between multiple modes. This allows the multi-way valve 1000 to have a mode switching function, expanding the adaptability of the multi-way valve 1000.

[0076] That is to say, the multi-way valve 1000 of the present application has both a mode switching function and a proportional adjustment function, so that the multi-way valve 1000 of the present application can replace a three-way valve and a four-way valve, improve the integration of the multi-way valve 1000, and expand the adaptability of the multi-way valve 1000. In this way, applying the multi-way valve 1000 to the thermal management system 3000 can effectively improve the integration of the thermal management system 3000 and reduce the control difficulty and cost of the thermal management system 3000.

[0077] In summary, the multi-way valve 1000 of the present application has a high degree of integration and can simultaneously meet the mode switching function and proportional adjustment function of the combination of a three-way valve and a four-way valve, so as to meet the needs of the thermal management system 3000 and reduce the cost of the thermal management system 3000.

[0078] In some examples, when the valve core 200 rotates relative to the valve body 100, the valve core 200 drives the first connecting port 211, the second connecting port 212, the regulating connecting port 213 and the switching connecting port 214 to rotate synchronously, so that the first connecting port 211, the second connecting port 212, the regulating connecting port 213 and the switching connecting port 214 can be connected to different valve ports 110, and the connecting area between the first connecting port 211, the second connecting port 212, the regulating connecting port 213 and the switching connecting port 214 and the valve port 110 can be controlled to ensure the working performance of the multi-way valve 1000.

[0079] It should also be noted that when the first communication port 211, the second communication port 212, the regulating communication port 213 and the switching communication port 214 are rotated to overlap or partially overlap with the corresponding valve port 110, the first communication port 211, the second communication port 212, the regulating communication port 213 and the switching communication port 214 can be connected to the valve port 110. At this time, the external medium can flow through the valve port 110 to the first communication port 211, the second communication port 212, the regulating communication port 213 and the switching communication port 214, and the external medium flowing into the first communication port 211, the second communication port 212, the regulating communication port 213 and the switching communication port 214 can flow into the first communication port 211, the second communication port 212, the regulating communication port 213 and the switching communication port 214. The medium then flows through the first switching flow channel 240 or the second switching flow channel 250, so that the external medium can be discharged through the valve port 110; when the first communicating port 211, the second communicating port 212, the regulating communicating port 213 and the switching communicating port 214 are rotated to be offset from the valve port 110, the first communicating port 211, the second communicating port 212, the regulating communicating port 213 and the switching communicating port 214 are not connected to the valve port 110. At this time, the external medium cannot flow into the first communicating port 211, the second communicating port 212, the regulating communicating port 213 and the switching communicating port 214, and the external medium located in the valve core 200 cannot be discharged either.

[0080] In addition, by changing the overlapping range of the first connecting port 211, the second connecting port 212, the regulating connecting port 213 and the switching connecting port 214 with the corresponding valve port 110, the connecting area of ​​the first connecting port 211, the second connecting port 212, the regulating connecting port 213 and the switching connecting port 214 with the corresponding valve port 110 can be changed.

[0081] Among them, the larger the overlapping range between the first connecting port 211, the second connecting port 212, the regulating connecting port 213 and the switching connecting port 214 and the corresponding valve port 110, the larger the connecting area between the first connecting port 211, the second connecting port 212, the regulating connecting port 213 and the switching connecting port 214 and the corresponding valve port 110, which is convenient for proportional adjustment.

[0082] It can be seen from the above structure that the multi-way valve 1000 of the embodiment of the present application is provided with at least five valve ports 110 on the valve body 100, and a first connecting port 211, a second connecting port 212, an adjusting connecting port 213 and a switching connecting port 214 are provided on the outer peripheral wall of the valve core 200, and a first switching flow channel 240 and at least one second switching flow channel 250 are provided inside the valve core 200, so that the multi-way valve 1000 has both a switching mode and a proportional adjustment mode. In this way, a multi-way valve 1000 can be used to replace a three-way valve and a four-way valve at the same time, thereby improving the integration of the multi-way valve 1000 and expanding the adaptability of the multi-way valve 1000. Applying the multi-way valve 1000 to the thermal management system 3000 and the integrated module 2000 can effectively improve the integration of the thermal management system 3000 and the integrated module 2000, and reduce the control difficulty and cost of the thermal management system 3000 and the integrated module 2000.

[0083] It can be understood that compared with the prior art, the present application sets a first connecting port 211, a second connecting port 212, an adjusting connecting port 213 and a switching connecting port 214 on the outer peripheral wall of the valve core 200, sets a first switching flow channel 240 and at least one second switching flow channel 250 inside the valve core 200, and sets at least five valve ports 110 on the valve body 100, which can improve the integration of the multi-way valve 1000 and expand the adaptability of the multi-way valve 1000, so as to improve the integration of the thermal management system 3000 and reduce the control difficulty and cost of the thermal management system 3000.

[0084] Optionally, the valve body 100 and the valve core 200 are coaxially arranged to ensure that the valve core 200 can effectively rotate relative to the valve body 100, thereby facilitating mode switching and proportional adjustment using the multi-way valve 1000.

[0085] In some embodiments, as shown in Figure 4, the valve body 100 has an open accommodating cavity 120, and the valve core 200 can be rotatably arranged in the accommodating cavity 120 through the opening to achieve rotational coordination between the valve body 100 and the valve core 200, while also reducing the difficulty of assembling the valve body 100 and the valve core 200.

[0086] In some embodiments, in combination with Figures 1, 2 and 4, the valve body 100 also includes a cover plate 130, which is detachably connected to the opening of the accommodating chamber 120 to close the opening, thereby facilitating the use of the valve body 100 to protect the valve core 200 and extend the service life of the valve core 200. At the same time, it can also prevent external debris from entering the accommodating chamber 120, ensure that the valve core 200 can effectively rotate relative to the valve body 100, and ensure the working performance of the multi-way valve 1000.

[0087] Optionally, as shown in FIG. 1 , FIG. 2 and FIG. 4 , the cover plate 130 is detachably connected to the opening of the accommodating cavity 120 via a fastener 140 to reduce the difficulty of connecting the cover plate 130 .

[0088] The fastener 140 mentioned here may be a bolt, a screw, etc.

[0089] In some embodiments, as shown in Figures 7 and 8, a plurality of regulating communication ports 213 are provided on the outer peripheral wall of the valve core 200, and the plurality of regulating communication ports 213 are connected via a first switching flow channel 240. In other words, external media flowing through the plurality of regulating communication ports 213 can flow through the first switching flow channel 240, thereby enabling the plurality of regulating communication ports 213 to communicate with the first communication port 211 and the second communication port 212 through the first switching flow channel 240, ensuring that external media can flow between the plurality of regulating communication ports 213 and the first communication port 211, and between the plurality of regulating communication ports 213 and the second communication port 212.

[0090] In addition, by arranging multiple regulating connecting ports 213 on the outer peripheral wall of the valve core 200, the multiple regulating connecting ports 213 can be independent of each other, thereby facilitating the coordination between the regulating connecting ports 213 and the valve port 110, so that the regulating connecting ports 213 and the valve port 110 can correspond one to one, ensuring the accuracy of the flow of the external medium, thereby ensuring the working performance of the multi-way valve 1000.

[0091] In some embodiments, as shown in Figures 7 and 9, a plurality of switching communication ports 214 are provided on the outer peripheral wall of the valve core 200, so that switching communication ports 214 are provided on both the first layer flow channel 260 and the second layer flow channel 270 below to ensure the working performance of the multi-way valve 1000.

[0092] In some embodiments, in combination with Figures 5, 7 and 8, the valve core 200 is provided with a first layer flow channel 260 and a second layer flow channel 270 on the rotation axis parallel to the valve core 200, the first layer flow channel 260 is provided with an adjusting communication port 213 and at least one switching communication port 214, and the second layer flow channel 270 is provided with a first communication port 211, a second communication port 212 and at least one switching communication port 214. Among them, the rotation axis of the valve core 200 mentioned here can be understood as the axis of the drive matching part 221 in Figure 5, that is, in the extension direction of the axis of the drive matching part 221, the valve core 200 is provided with a first layer flow channel 260 and a second layer flow channel 270, the first layer flow channel 260 is provided with an adjusting connecting port 213 and at least one switching connecting port 214, and the second layer flow channel 270 is provided with a first connecting port 211, a second connecting port 212 and at least one switching connecting port 214, so as to realize the setting of the first connecting port 211, the second connecting port 212, the adjusting connecting port 213 and the switching connecting port 214 on the valve core 200, reducing the molding difficulty of the first connecting port 211, the second connecting port 212, the adjusting connecting port 213 and the switching connecting port 214, and facilitating the use of the valve core 200 to control the flow direction of the external medium, so that the multi-way valve 1000 can have a switching mode and a proportional adjustment mode at the same time, thereby improving the integration of the multi-way valve 1000.

[0093] In addition, the above can also be understood as that the valve core 200 is divided into two layers of flow channels (a first layer of flow channel 260 and a second layer of flow channel 270), and the communication ports on the two layers of flow channels can be connected.

[0094] In some embodiments, as shown in FIG. 5 , FIG. 7 and FIG. 8 , the first layer flow channel 260 is provided with a plurality of regulating communication ports 213 , so as to realize setting a plurality of regulating communication ports 213 on the valve core 200 and ensure the working performance of the multi-way valve 1000 .

[0095] In some embodiments, in combination with Figures 5, 7 and 9, the first layer flow channel 260 is provided with two groups of first switching groups 261, each group of first switching groups 261 includes at least two switching communication ports 214 that are circumferentially spaced and connected, and the second layer flow channel 270 is provided with two groups of second switching groups 271, each group of second switching groups 271 includes at least two switching communication ports 214 that are circumferentially spaced and connected, and each group of first switching groups 261 is connected to a group of second switching groups 271 through the second switching flow channel 250. That is to say, a plurality of switching connecting ports 214 are provided on the first layer flow channel 260 and the second layer flow channel 270, and the switching connecting ports 214 on the first layer flow channel 260 can be connected to the plurality of switching connecting ports 214 on the second layer flow channel 270 through the second switching flow channel 250, so that the external medium flowing from the switching connecting ports 214 to the valve core 200 can flow between the first layer flow channel 260 and the second layer flow channel 270, so as to realize the mode switching function of the multi-way valve 1000 by utilizing the first switching group 261 and the second switching group 271, so that the multi-way valve 1000 can switch between multiple groups of modes to adjust the flow direction of the external medium in the multi-way valve 1000 and ensure the working performance of the thermal management system 3000 and the integrated module 2000.

[0096] It should be noted that by configuring each first switching group 261 and each second switching group 271 to include at least two switching communication ports 214 that are circumferentially spaced and connected, so that the switching communication ports 214 can be independent of each other, it is convenient to realize the coordination between the switching communication ports 214 and the valve port 110, so that the switching communication ports 214 and the valve port 110 can correspond one to one, thereby ensuring the accuracy of the flow of the external medium and thus ensuring the working performance of the multi-way valve 1000.

[0097] In some examples, each first switching group 261 is connected to a second switching group 271 through the second switching channel 250. When the external medium enters the valve core 200 through the first switching group 261, the external medium can flow to the second switching group 271 under the guidance of the second switching channel 250. When the switching connection port 214 in the second switching group 271 is connected to the corresponding valve port 110, the external medium can be discharged from the valve port 110 to guide the external medium.

[0098] Correspondingly, when the external medium enters the valve core 200 through the second switching group 271, the external medium can flow to the first switching group 261 under the guidance of the second switching channel 250. When the switching connection port 214 in the first switching group 261 is connected to the corresponding valve port 110, the external medium can also be discharged from the valve port 110 to guide the external medium.

[0099] It should be noted that, for the sake of convenience of description, in combination with Figures 7, 8 and 12, the two switching connecting ports 214 in one group of the first switching groups 261 on the first layer flow channel 260 are defined as port a and port b; the two switching connecting ports 214 in another group of the first switching group 261 on the first layer flow channel 260 are defined as port c and port d.

[0100] 9 and 13 , the two switching communication ports 214 in one of the second switching groups 271 on the second layer flow channel 270 are defined as port A and port H; the two switching communication ports 214 in another of the second switching groups 271 on the second layer flow channel 270 are defined as port D and port E.

[0101] 5 , 12 and 13 , in the extension direction of the rotation axis of the valve core 200 , port a on the first layer flow channel 260 faces port A on the second layer flow channel 270 ; port d on the first layer flow channel 260 faces port D on the second layer flow channel 270 .

[0102] In some embodiments, as shown in conjunction with Figures 5 and 7 , the valve core 200 is cylindrical, and the regulating communication port 213 and the two first switching groups 261 are sequentially arranged circumferentially of the valve core 200. The cylindrical shape of the valve core 200 facilitates the rotational coordination between the valve core 200 and the valve body 100, reduces the difficulty of rotating the valve core 200, and reduces the resistance of the valve core 200 to the external medium when the external medium flows through the valve core 200, thereby reducing the pressure drop and flow loss of the external medium and ensuring the performance of the multi-way valve 1000. By sequentially arranging the regulating communication port 213 and the two first switching groups 261 circumferentially of the valve core 200, the space on the valve core 200 is rationally utilized, ensuring that the valve core 200 can be simultaneously provided with the regulating communication port 213 and the two first switching groups 261, thereby ensuring that the multi-way valve 1000 can be controlled to switch between multiple modes when the valve core 200 rotates.

[0103] It should be noted that the above-mentioned regulating connecting ports 213 and two groups of first switching groups 261 are arranged sequentially in the circumferential direction of the valve core 200, which means that the regulating connecting ports 213 and two groups of first switching groups 261 are arranged sequentially in the circumferential direction of the first layer flow channel 260, so that a plurality of regulating connecting ports 213 and a plurality of switching connecting ports 214 are provided on the first layer flow channel 260.

[0104] Optionally, in combination with Figures 5 and 9, the first connecting port 211, the second connecting port 212 and the two groups of second switching groups 271 are arranged sequentially in the circumferential direction of the second layer flow channel 270 to achieve rational utilization of the space on the second layer flow channel 270, ensuring that the second layer flow channel 270 is provided with a first connecting port 211, a second connecting port 212 and at least one switching connecting port 214, so that the outer peripheral wall of the valve core 200 of the present application is provided with a first connecting port 211, a second connecting port 212, multiple adjusting connecting ports 213 and multiple switching connecting ports 214.

[0105] In some embodiments, as shown in Figures 1, 2, and 3, at least five valve ports 110 are provided on the same sidewall of the valve body 100, which is arranged parallel to the rotation axis of the valve core 200. In other words, providing at least five valve ports 110 on the sidewall of the valve body 100 that is arranged parallel to the rotation axis of the valve core 200 facilitates communication between the valve ports 110 and the first communication port 211, the second communication port 212, the adjustment communication port 213, and the switching communication port 214, while also reducing the difficulty of molding the multiple valve ports 110.

[0106] In some embodiments, as shown in conjunction with FIG2 and FIG3 , at least five valve ports 110 are provided on the bottom wall 150 of the valve body 100. This allows at least five valve ports 110 to be provided on the side wall of the valve body 100 that is parallel to the rotation axis of the valve core 200, and allows the valve ports 110 to be formed on the bottom surface of the valve body 100. This reduces the difficulty of molding the valve ports 110 and also reduces the difficulty of coordinating the valve ports 110 with the first communication port 211, the second communication port 212, the adjustment communication port 213, and the switching communication port 214. Furthermore, water inlet and outlet can be achieved at the same end of the multi-way valve 1000, further simplifying the structure of the multi-way valve 1000, making the multi-way valve 1000 smaller and easier to control.

[0107] In other words, the multi-way valve 1000 of the present application has a compact structure and is easy to control.

[0108] In some embodiments, as shown in FIG2 and FIG3 , the at least five valve ports 110 include two rows of valve ports 110, which are arranged sequentially in the direction of the rotation axis of the valve core 200. One row of valve ports 110 includes a first valve port 111, a second valve port 112, and a third valve port 113 arranged at intervals, and the other row of valve ports 110 includes a fourth valve port 114 and a fifth valve port 115 arranged at intervals. The first valve port 111, the second valve port 112, and the third valve port 113 are staggered with the fourth valve port 114 and the fifth valve port 115 in the direction of the rotation axis of the valve core 200. This facilitates the switching function and proportional adjustment function of the multi-way valve 1000 and improves the integration of the multi-way valve 1000.

[0109] It should be noted that the above-mentioned first valve port 111, second valve port 112 and third valve port 113 and the fourth valve port 114 and fifth valve port 115 are staggered in the extension direction of the rotation axis of the valve core 200, which means that in the extension direction of the rotation axis of the valve core 200, the valve port 110 on one column is opposite to the position between two adjacent valve ports 110 on the other column.

[0110] For example: as shown in Figure 3, the fourth valve port 114 is opposite to the position between the first valve port 111 and the second valve port 112, the fifth valve port 115 is opposite to the position between the second valve port 112 and the third valve port 113, and the second valve port 112 is opposite to the position between the fourth valve port 114 and the fifth valve port 115, so as to realize the switching function and proportional adjustment function of the multi-way valve 1000 and improve the integration of the multi-way valve 1000.

[0111] In some embodiments, in combination with Figures 1, 3 and 4, the side wall of the accommodating cavity 120 of the valve body 100 is provided with a bypass port 121 connected to the valve port 110. The bypass port 121 is used to connect with the corresponding first connecting port 211, the second connecting port 212, multiple adjusting connecting ports 213 and multiple switching connecting ports 214, so as to realize the connection between the valve core 200 and the valve body 100, which is convenient for using the multi-way valve 1000 to control the flow direction of the external medium.

[0112] Optionally, in combination with Figures 1, 3 and 4, the valve body 100 includes a connecting channel 160, and the opposite ends of the connecting channel 160 are respectively connected to the avoidance port 121 and the valve port 110, thereby realizing the connection between the avoidance port 121 and the valve port 110, so as to ensure that the external medium flowing through the valve port 110 can flow into the avoidance port 121, and then flow through the avoidance port 121 to the first connecting port 211, the second connecting port 212, the adjusting connecting port 213 or the switching connecting port 214, or, ensure that the external medium discharged through the avoidance port 121 can flow to the valve port 110.

[0113] Optionally, as shown in Figure 4, a plurality of avoidance openings 121 are provided on the side wall of the accommodating cavity 120 of the valve body 100. In the extension direction of the rotation axis of the valve core 200, the plurality of avoidance openings 121 are formed into two rows, and the plurality of avoidance openings 121 correspond one-to-one to the plurality of valve openings 110.

[0114] That is to say, five avoidance openings 121 are provided on the side wall of the accommodating cavity 120, two of which are formed in a row at one end of the axial direction of the accommodating cavity 120, and the other three avoidance openings 121 are formed in a row at the other end of the axial direction of the accommodating cavity 120.

[0115] Optionally, two of the avoidance ports 121 face the first layer flow channel 260 and are used to cooperate with the multiple regulating communication ports 213 and the multiple switching communication ports 214 on the first layer flow channel 260, and the other three avoidance ports 121 face the second layer flow channel 270 and are used to cooperate with the first communication port 211, the second communication port 212 and the multiple switching communication ports 214 on the second layer flow channel 270, so that the first valve port 111, the second valve port 112 and the third valve port 113 can cooperate with the first communication port 211, the second communication port 212 and the multiple switching communication ports 214 on the second layer flow channel 270, and the fourth valve port 114 and the fifth valve port 115 can cooperate with the multiple regulating communication ports 213 and the multiple switching communication ports 214 on the first layer flow channel 260.

[0116] In some embodiments, as shown in conjunction with FIG7 and FIG8 , the first switching flow channel 240 includes a communication flow channel 241, a first flow channel 242, and a second flow channel 243. The communication flow channel 241 is used to communicate with the adjustable communication port 213. This enables communication between the adjustable communication port 213 and the first switching flow channel 240, ensuring that the external medium flowing through the adjustable communication port 213 can flow to the first switching flow channel 240. Correspondingly, it can also ensure that the external medium flowing through the first switching flow channel 240 can flow to the adjustable communication port 213.

[0117] It should be noted that, for the convenience of description, in combination with FIG7 , FIG8 and FIG12 , the plurality of regulating communication ports 213 are respectively defined as port e, port f, port g and port h.

[0118] 5 , 12 and 13 , in the extension direction of the rotation axis of the valve core 200 , the e port on the first layer flow channel 260 faces the E port on the second layer flow channel 270 ; the h port on the first layer flow channel 260 faces the H port on the second layer flow channel 270 .

[0119] Optionally, as shown in FIG. 7 and FIG. 8 , the first flow channel 242 and the second flow channel 243 are spaced apart, the first flow channel 242 connects the communication flow channel 241 and the first communication port 211 , and the second flow channel 243 connects the communication flow channel 241 and the second communication port 212 . Among them, since the connecting flow channel 241 is connected to the regulating connecting port 213, the first flow channel 242 is set to connect the connecting flow channel 241 and the first connecting port 211, so that the regulating connecting port 213 and the first connecting port 211 can be connected to each other, thereby ensuring that the external medium can flow between the regulating connecting port 213 and the first connecting port 211; the second flow channel 243 is connected to the connecting flow channel 241 and the second connecting port 212, so that the regulating connecting port 213 and the second connecting port 212 can be connected to each other, thereby ensuring that the external medium can flow between the regulating connecting port 213 and the second connecting port 212, that is, ensuring that the first connecting port 211 and the second connecting port 212 can both be connected to the first switching flow channel 240, so that the multi-way valve 1000 has a proportional adjustment mode, enriching the function of the multi-way valve 1000, thereby expanding the adaptability of the multi-way valve 1000.

[0120] In some embodiments, as shown in conjunction with Figures 7, 8, and 9, the first flow channel 242 includes a centrally located intermediate flow channel 2421, which communicates with the connecting flow channel 241, and the second flow channel 243 is located outside the intermediate flow channel 2421. This ensures that the first flow channel 242 can communicate with the connecting flow channel 241 and the first communicating port 211, and that the second flow channel 243 can communicate with the connecting flow channel 241 and the second communicating port 212, while also achieving rational utilization of the space within the valve core 200, ensuring that the connecting flow channel 241, the first flow channel 242, and the second flow channel 243 can be disposed within the valve core 200. This also enables the multi-way valve 1000 to have a proportional adjustment mode, enriching the functionality of the multi-way valve 1000.

[0121] It should be noted that, for the convenience of description, in combination with FIG. 7 , FIG. 8 and FIG. 12 , the first communication port 211 is defined as port B; and the second communication port 212 is defined as port G.

[0122] 5 , 12 and 13 , in the extension direction of the rotation axis of the valve core 200 , the B port on the second layer flow channel 270 faces the b port on the first layer flow channel 260 ; the G port on the second layer flow channel 270 faces the g port on the first layer flow channel 260 .

[0123] Optionally, in combination with Figures 5, 7 and 13, two sealing plates 272 are further provided on the peripheral wall of the second layer flow channel 270, one sealing plate 272 is located between port B and port D, and the other sealing plate 272 is located between port E and port G. When the sealing plate 272 is facing the valve port 110, the external medium located in the valve core 200 cannot be discharged through the valve port 110, so as to realize the mode switching function of the multi-way valve 1000.

[0124] 5 , 12 and 13 , in the extension direction of the rotation axis of the valve core 200 , the blocking plate 272 located between the B port and the D port on the second layer flow channel 270 faces the C port on the first layer flow channel 260 ; the blocking plate 272 located between the E port and the G port on the second layer flow channel 270 faces the F port on the first layer flow channel 260 .

[0125] In summary, in combination with Figures 12 and 13, the first layer of flow channel 260 has port a, port b, port c, port d, port e, port f, port g and port h formed on the peripheral wall in sequence; the second layer of flow channel 270 has port A, port B, sealing plate 272, port D, port E, sealing plate 272, port G and port H formed on the peripheral wall in sequence. In the extension direction of the rotation axis of the valve core 200, port a is opposite to port A, port b is opposite to port B, port c is opposite to sealing plate 272, port d is opposite to port D, port e is opposite to port E, port f is opposite to sealing plate 272, port g is opposite to port G, and port h is opposite to port H.

[0126] Among them, port a and port b are both switching connecting ports 214 on the first layer flow channel 260 and form a first switching group 261; port c and port d are both switching connecting ports 214 on the first layer flow channel 260 and form a first switching group 261; port e, port f, port g and port h are all regulating connecting ports 213; port A and port H are both switching connecting ports 214 on the second layer flow channel 270 and form a second switching group 271; port D and port E are both switching connecting ports 214 on the second layer flow channel 270 and form a second switching group 271; port B is the first connecting port 211 on the first layer flow channel 260; port G is the second connecting port 212 on the first layer flow channel 260.

[0127] Through the above configuration, the multi-way valve 1000 can have multiple modes to expand the adaptability of the multi-way valve 1000.

[0128] In some examples, as shown in FIG14 , in the first working mode, the valve core 200 rotates so that the port b on the first layer flow channel 260 is connected to the fifth valve port 115, the port h on the first layer flow channel 260 is connected to the fourth valve port 114, the blocking plate 272 located between the ports B and D on the second layer flow channel 270 is connected to the third valve port 113, and the port G on the second layer flow channel 270 is connected to the first valve port 111. Since the port a on the first layer flow channel 260 in FIG14 is opposite to the fourth valve port 114 and the fifth valve port The positions between the ports 115 can be understood as, port A on the second layer flow channel 270 is opposite to the second valve port 112, that is, the first valve port 111 is opposite to port G on the second layer flow channel 270, the second valve port 112 is opposite to port A on the second layer flow channel 270, the third valve port 113 is opposite to the sealing plate 272 between ports B and D on the second layer flow channel 270, the fourth valve port 114 is opposite to port h on the first layer flow channel 260, and the fifth valve port 115 is opposite to port b on the first layer flow channel 260.

[0129] At this time, when the external medium can enter the valve core 200 from the port b and the port h on the first layer flow channel 260, or enter the valve core 200 from the port A and / or the port G on the second layer flow channel 270. Among them, when the external medium enters the valve core 200 from the port b and the port h on the first layer flow channel 260, since the port b is the switching communication port 214 and is connected to the switching communication port 214 on the second layer flow channel 270 through the second switching flow channel 250, the external medium in the port b can flow toward the port A and the port H on the second layer flow channel 270 through the second switching flow channel 250. Since the port H is not connected to the valve port 110, the port A is facing the second valve port 112. At this time, the external medium entering the valve core 200 through the port b can be discharged through the second valve port 112. Accordingly, the external medium entering the valve core 200 through the second valve port 112 is discharged. The medium can also be discharged through port B; because port H is the regulating connecting port 213 and is connected to the first connecting port 211 and the second connecting port 212 through the first switching channel 240, the external medium in port H can flow toward port B and port G on the second layer channel 270 through the first switching channel 240. Since port B is not connected to the valve port 110, port G is facing the first valve port 111. At this time, the external medium entering the valve core 200 through port H can be discharged through the first valve port 111. Correspondingly, the external medium entering the valve core 200 through the first valve port 111 can also be discharged through port H to realize the first working mode of the multi-way valve 1000.

[0130] As shown in FIG15 , in the second working mode, the valve core 200 rotates so that the port a on the first layer flow channel 260 is connected to the fifth valve port 115, the port g on the first layer flow channel 260 is connected to the fourth valve port 114, the port B on the second layer flow channel 270 is connected to the third valve port 113, and the blocking plate 272 located between the ports E and G on the second layer flow channel 270 blocks the first valve port 111. Because the port h on the first layer flow channel 260 in FIG15 is facing the fourth valve port 114 and the fifth valve port 113, the valve core 200 rotates so that the port a on the first layer flow channel 260 is connected to the fifth valve port 115, the port g on the first layer flow channel 260 is connected to the fourth valve port 114, the port B on the second layer flow channel 270 is connected to the third valve port 113, and the blocking plate 272 located between the ports E and G on the second layer flow channel 270 blocks the first valve port 111. The position between the valve ports 115 can be understood as that the H port on the second layer flow channel 270 is opposite to the second valve port 112, that is, the first valve port 111 is blocked by the sealing plate 272 located between the E port and the G port, the second valve port 112 is opposite to the H port on the second layer flow channel 270, the third valve port 113 is opposite to the B port on the second layer flow channel 270, the fourth valve port 114 is opposite to the g port on the first layer flow channel 260, and the fifth valve port 115 is opposite to the a port on the first layer flow channel 260.

[0131] At this time, when the external medium can enter the valve core 200 from the port a and the port g on the first layer flow channel 260, or enter the valve core 200 from the port B and the port H on the second layer flow channel 270. Among them, when the external medium enters the valve core 200 from the port a and the port g on the first layer flow channel 260, because the port a is the switching communication port 214 and is connected to the switching communication port 214 on the second layer flow channel 270 through the second switching flow channel 250, the external medium in the port a can flow toward the port A and the port H on the second layer flow channel 270 through the second switching flow channel 250. Because the port A is not connected to the valve port 110, the port H is facing the second valve port 112. At this time, the external medium entering the valve core 200 through the port a can be discharged through the second valve port 112. Accordingly, the external medium entering the valve core 200 through the second valve port 112 is discharged. The medium can also be discharged through port a; because port g is the regulating connecting port 213 and is connected to the first connecting port 211 and the second connecting port 212 through the first switching channel 240, the external medium in port g can flow toward port B and port G on the second layer channel 270 through the first switching channel 240. Since port G is not connected to the valve port 110, port B is facing the third valve port 113. At this time, the external medium entering the valve core 200 through port g can be discharged through the third valve port 113. Correspondingly, the external medium entering the valve core 200 through the third valve port 113 can also be discharged through port g to realize the second working mode of the multi-way valve 1000.

[0132] As shown in FIG16 , in the case of the third working mode, the valve core 200 rotates so that a portion of the port a and a portion of the port b on the first layer flow channel 260 are simultaneously connected to the fifth valve port 115, a portion of the port g and a portion of the port h on the first layer flow channel 260 are connected to the fourth valve port 114, a portion of the port B on the second layer flow channel 270 is connected to the third valve port 113, and a portion of the port G on the second layer flow channel 270 is connected to the first valve port 111. Since a portion of the port h and a portion of the port a on the first layer flow channel 260 in FIG16 are facing the fourth valve port The position between the port 114 and the fifth valve port 115 can be understood as that a part of the A port and a part of the H port on the second layer flow channel 270 are facing the second valve port 112, that is, the first valve port 111 is facing the G port on the second layer flow channel 270, the second valve port 112 is facing the A port and the H port on the second layer flow channel 270, the third valve port 113 is facing the B port on the second layer flow channel 270, the fourth valve port 114 is facing the g port and the h port on the first layer flow channel 260, and the fifth valve port 115 is facing the a port and the b port on the first layer flow channel 260.

[0133] At this time, the external medium can enter the valve core 200 from the port a, port b, port g, and port h on the first layer flow channel 260, or enter the valve core 200 from the port B, port A, port H, and port G on the second layer flow channel 270. Specifically, when the external medium enters the valve core 200 from the port a, port b, port g, and port h on the first layer flow channel 260, since the port a and port b are the switching communication ports 214 and are connected to the switching communication ports 214 on the second layer flow channel 270 through the second switching flow channel 250, the external medium in the port a and port b can flow toward the port A and port H on the second layer flow channel 270 through the second switching flow channel 250. The port A and port H are directly opposite to the second valve port 112. At this time, the external medium entering the valve core 200 through the port a and port b can be discharged through the second valve port 112. Correspondingly, the external medium entering the valve core 200 through the second valve port 112 can also be discharged through the port a and port b. The g port and the h port are the regulating connecting port 213 and are connected to the first connecting port 211 and the second connecting port 212 through the first switching channel 240. At this time, the external medium in the g port and the h port can flow toward the B port and the G port on the second layer channel 270 through the first switching channel 240. Because the B port is facing the third valve port 113 and the G port is facing the first valve port 111, the external medium entering the valve core 200 through the g port and the h port can be discharged through the first valve port 111 and the third valve port 113 respectively. Correspondingly, the external medium entering the valve core 200 through the first valve port 111 and the third valve port 113 can also be discharged through the g port and the h port to realize the third working mode of the multi-way valve 1000.

[0134] In some examples, as shown in FIG17 , in the fourth working mode, the valve core 200 rotates so that the port f on the first layer flow channel 260 is connected to the fifth valve port 115, the port d on the first layer flow channel 260 is connected to the fourth valve port 114, the port G on the second layer flow channel 270 is connected to the third valve port 113, and the blocking plate 272 located between the ports B and D on the second layer flow channel 270 blocks the first valve port 111. Since the port e on the first layer flow channel 260 in FIG17 is facing the fourth valve port 114, 4 and the fifth valve port 115 can be understood as that the E port on the second layer flow channel 270 is opposite to the second valve port 112, that is, the first valve port 111 is blocked by the blocking plate 272 located between the B port and the D port, the second valve port 112 is opposite to the E port on the second layer flow channel 270, the third valve port 113 is opposite to the G port on the second layer flow channel 270, the fourth valve port 114 is opposite to the d port on the first layer flow channel 260, and the fifth valve port 115 is opposite to the f port on the first layer flow channel 260.

[0135] At this time, the external medium can enter the valve core 200 from the port f and the port d on the first layer flow channel 260, or enter the valve core 200 from the port G and the port E on the second layer flow channel 270. When the external medium enters the valve core 200 from the port f and the port d on the first layer flow channel 260, since the port f is the regulating communication port 213 and is connected to the first communication port 211 and the second communication port 212 through the first switching flow channel 240, the external medium in the port f can flow toward the port B and the port G on the second layer flow channel 270 through the first switching flow channel 240. Since the port B is not connected to the valve port 110 and the port G is facing the third valve port 113, the external medium entering the valve core 200 through the port f can be discharged through the third valve port 113. Correspondingly, the external medium entering the valve core 200 through the third valve port 113 can also be discharged. It can be discharged through port f; because port d is the switching connecting port 214 and is connected to the switching connecting port 214 on the second layer channel 270 through the second switching channel 250, the external medium in port d can flow toward port D and port E on the second layer channel 270 through the second switching channel 250. Since port D is not connected to the valve port 110, port E is facing the second valve port 112. At this time, the external medium entering the valve core 200 through port d can be discharged through the second valve port 112. Correspondingly, the external medium entering the valve core 200 through the second valve port 112 can also be discharged through port d to realize the fourth working mode of the multi-way valve 1000.

[0136] In some examples, as shown in FIG18 , in the fifth working mode, the valve core 200 rotates so that the e port on the first layer flow channel 260 is connected to the fifth valve port 115, the c port on the first layer flow channel 260 is connected to the fourth valve port 114, the blocking plate 272 located between the E port and the G port on the second layer flow channel 270 blocks the third valve port 113, and the B port on the second layer flow channel 270 is connected to the first valve port 111. Since the d port on the first layer flow channel 260 in FIG18 is opposite to the fourth valve port 114 and the fifth valve port 114, the valve core 200 rotates so that the e port on the first layer flow channel 260 is connected to the fifth valve port 115, the c port on the first layer flow channel 260 is connected to the fourth valve port 114, and the blocking plate 272 located between the E port and the G port on the second layer flow channel 270 blocks the third valve port 113. The position between the ports 115 can be understood as that the D port on the second layer flow channel 270 is opposite to the second valve port 112, that is, the first valve port 111 is opposite to the B port on the second layer flow channel 270, the second valve port 112 is opposite to the D port on the second layer flow channel 270, the third valve port 113 is blocked by the blocking plate 272 located between the E port and the G port on the second layer flow channel 270, the fourth valve port 114 is opposite to the C port on the first layer flow channel 260, and the fifth valve port 115 is opposite to the e port on the first layer flow channel 260.

[0137] At this time, when the external medium can enter the valve core 200 from the e port and the c port on the first layer flow channel 260, or enter the valve core 200 from the D port and the B port on the second layer flow channel 270. Among them, when the external medium enters the valve core 200 from the e port and the c port on the first layer flow channel 260, since the e port is the regulating communication port 213 and is connected to the first communication port 211 and the second communication port 212 through the first switching flow channel 240, the external medium in the e port can flow toward the B port and the G port on the second layer flow channel 270 through the first switching flow channel 240. Since the G port is not connected to the valve port 110 and the B port is facing the first valve port 111, the external medium entering the valve core 200 through the e port can be discharged through the first valve port 111. Correspondingly, the external medium entering the valve core 200 through the first valve port 111 can also be discharged. It can be discharged through port e; because port c is the switching connecting port 214 and is connected to the switching connecting port 214 on the second layer channel 270 through the second switching channel 250, the external medium in port c can flow toward port D and port E on the second layer channel 270 through the second switching channel 250. Since port E is not connected to the valve port 110, port D is facing the second valve port 112. At this time, the external medium entering the valve core 200 through port c can be discharged through the second valve port 112. Correspondingly, the external medium entering the valve core 200 through the second valve port 112 can also be discharged through port c to realize the fifth working mode of the multi-way valve 1000.

[0138] In some examples, as shown in FIG19 , in the sixth working mode, the valve core 200 rotates so that a portion of the e port and a portion of the f port on the first layer flow channel 260 are connected to the fifth valve port 115, a portion of the c port and a portion of the d port on the first layer flow channel 260 are connected to the fourth valve port 114, a portion of the G port on the second layer flow channel 270 is connected to the third valve port 113, and a portion of the B port on the second layer flow channel 270 is connected to the first valve port 111. Since a portion of the d port and a portion of the e port on the first layer flow channel 260 in FIG19 are facing each other, The position between the fourth valve port 114 and the fifth valve port 115 can be understood as that a part of the D port and a part of the E port on the second layer flow channel 270 are facing the second valve port 112, that is, the first valve port 111 is facing the B port on the second layer flow channel 270, the second valve port 112 is facing the D port and the E port on the second layer flow channel 270, the third valve port 113 is facing the G port on the second layer flow channel 270, the fourth valve port 114 is facing the c port and the d port on the first layer flow channel 260, and the fifth valve port 115 is facing the e port and the f port on the first layer flow channel 260.

[0139] At this time, the external medium can enter the valve core 200 from the c port, d port, e port, and f port on the first layer flow channel 260, or enter the valve core 200 from the G port, E port, D port, and B port on the second layer flow channel 270. Specifically, when the external medium enters the valve core 200 from the e port and f port on the first layer flow channel 260, since the e port and f port are the regulating communication ports 213 and are connected to the first communication port 211 and the second communication port 212 through the first switching flow channel 240, the external medium in the e port and f port can flow toward the B port and G port on the second layer flow channel 270 through the first switching flow channel 240. Since the G port is facing the third valve port 113 and the B port is facing the first valve port 111, the external medium entering the valve core 200 through the e port and f port can be discharged through the first valve port 111 and the third valve port 113. Accordingly, it enters the valve core 200 through the first valve port 111 and the third valve port 113. The external medium in 00 can also be discharged through port e and port f; because port c and port d are switching connecting ports 214 and are connected to the switching connecting port 214 on the second layer flow channel 270 through the second switching flow channel 250, the external medium in port c and port d can flow toward port D and port E on the second layer flow channel 270 through the second switching flow channel 250. Since port D and port E are both facing the second valve port 112, the external medium entering the valve core 200 through port c and port d can be discharged through the second valve port 112. Correspondingly, the external medium entering the valve core 200 through the second valve port 112 can also be discharged through port c and port d to realize the sixth working mode of the multi-way valve 1000.

[0140] It should be noted that the above working modes are only examples and do not represent limitations on this application.

[0141] In summary, the present application creatively sets the position of the valve port 110, sets a first connecting port 211, a second connecting port 212, multiple adjustment connecting ports 213 and multiple switching connecting ports 214 on the outer wall of the valve core 200, and sets a first switching flow channel 240 and at least one second switching flow channel 250 inside the valve core 200. By rotating the angular position of the valve core 200, different connection relationships between the valve ports 110 required by the system can be output, so that the multi-way valve 1000 can output the mode switching function and proportional adjustment function of the traditional three-way valve and four-way valve combined together.

[0142] Among them, the first working mode in Figure 14, the second working mode in Figure 15, the fourth working mode in Figure 17, and the fifth working mode in Figure 18 are used to perform the mode switching function; the third working mode in Figure 16 and the sixth working mode in Figure 19 are used to perform the proportional adjustment function. Compared with the combination of traditional three-way valves and four-way valves, the multi-way valve 1000 not only reduces the cost, but also further improves the breadth of its application.

[0143] In some embodiments, as shown in FIG14 , the multi-way valve 1000 further includes a sealing member 300 disposed between the valve core 200 and the valve body 100 to achieve a sealed connection between the valve core 200 and the valve body 100, thereby facilitating sealed communication between the valve port 110 and the first communication port 211, the second communication port 212, the plurality of regulating communication ports 213, and the plurality of switching communication ports 214, ensuring that external media can effectively flow between the valve core 200 and the valve body 100, thereby ensuring the flow diversion effect of the multi-way valve 1000 and avoiding loss of external media.

[0144] In some embodiments, the sealing member 300 is formed as a rubber member to ensure the sealing effect of the sealing member 300 .

[0145] In some embodiments, the inner wall of the valve body 100 is provided with a groove for accommodating the sealing member 300. The sealing member 300 is conveniently placed in the groove. This not only achieves a sealed connection between the valve core 200 and the valve body 100 by utilizing the sealing member 300, but also reduces the difficulty of securing the sealing member 300 and ensures the quality of securing. This improves the sealing effect of the sealing member 300 and ensures the working performance of the multi-way valve 1000.

[0146] In some embodiments, as shown in conjunction with Figures 5, 7, 9, and 11, the valve core 200 includes a body 210, a first end cap 220, and a second end cap 230. The first communication port 211, the second communication port 212, the switching communication port 214, and the regulating communication port 213 are respectively provided on the body 210. This allows the first communication port 211, the second communication port 212, the regulating communication port 213, and the switching communication port 214 to be formed on the valve core 200, thereby ensuring the working performance of the valve core 200 and reducing the difficulty of molding the first communication port 211, the second communication port 212, the switching communication port 214, and the regulating communication port 213, thereby reducing the difficulty of molding the valve core 200.

[0147] Optionally, as shown in FIG. 11 , the main body 210 is formed into a cylindrical shape, so that the valve core 200 is formed into a cylindrical shape, thereby facilitating the rotational cooperation between the valve core 200 and the valve body 100 and reducing the difficulty of rotating the valve core 200 .

[0148] Optionally, as shown in Figures 5 and 11, a first end cap 220 and a second end cap 230 are disposed at opposite ends of the body 210. The first end cap 220 is provided with a drive engagement portion 221 adapted to connect to a driver. The second end cap 230 is rotatably supported by the valve body 100, and the driver drives the valve core 200 to rotate. In other words, the first end cap 220 is configured to engage with the driver, while the second end cap 230 is configured to engage with the valve body 100, thereby ensuring that the valve core 200 can effectively rotate relative to the valve body 100 and thus maintaining the operating performance of the multi-way valve 1000.

[0149] Optionally, the driving member is a driving motor, which can ensure the driving effect of the driving member while utilizing the driving member to drive the valve core 200 to rotate.

[0150] It should be noted that by providing a drive fitting portion 221 on the first end cover 220, the first end cover 220 is connected to the drive member through the drive fitting portion 221 to realize the fitting connection between the valve core 200 and the drive member, thereby facilitating the use of the drive member to drive the valve core 200 to rotate, and at the same time reducing the difficulty of fitting between the drive member and the valve core 200.

[0151] In some embodiments, as shown in Figures 5 and 11, the drive fitting portion 221 is a fitting shaft, which is used to fit and connect with the output end of the driving member to achieve a fitting connection between the first end cover 220 and the driving member, thereby facilitating the use of the driving member to drive the first end cover 220 to rotate, that is, to achieve the use of the driving member to drive the valve core 200 to rotate.

[0152] In addition, the second end cover 230 is rotatably supported on the valve body 100. While realizing the rotational coordination between the valve core 200 and the valve body 100, the valve body 100 can also be used to support the valve core 200 to improve the stability of the valve core 200 during rotation, making it easier to use the valve core 200 and the valve body 100 to control the multi-way valve 1000 to switch between multiple modes, thereby ensuring the working performance of the multi-way valve 1000.

[0153] In some embodiments, a protrusion is respectively provided on the first end cover 220 and the second end cover 230, and a matching portion is provided on the main body 210. The protrusion can be limitedly matched in the matching portion to achieve limited matching of the first end cover 220, the second end cover 230 and the main body 210, thereby facilitating the arrangement of the first end cover 220 and the second end cover 230 at both ends of the main body 210, and reducing the difficulty of matching the first end cover 220, the second end cover 230 and the main body 210, thereby reducing the difficulty of assembling the valve core 200.

[0154] Of course, in some other embodiments, a convex portion may be provided on the main body 210 , and a matching portion may be provided on the first end cover 220 and the second end cover 230 , and this application does not impose any specific limitation thereto.

[0155] In some examples, the first end cover 220 and the second end cover 230 are respectively connected to the main body 210 by laser welding to ensure the connection strength between the first end cover 220 and the second end cover 230 and the main body 210, thereby ensuring the structural stability of the valve core 200.

[0156] In some embodiments, the driving fitting portion 221 is rotationally supported on the cover plate 130 to achieve rotational support cooperation between the driving fitting portion 221 and the valve body 100 , further improving the stability of the valve core 200 during rotation.

[0157] In summary, one end of the valve core 200 is rotationally matched with the valve body 100 through the first end cover 220, and the other end of the valve core 200 is rotationally matched with the valve body 100 through the second end cover 230. This ensures that the valve core 200 can effectively rotate relative to the valve body 100 while also ensuring the stability of the valve core 200 during rotation, thereby ensuring the working performance of the multi-way valve 1000.
