However, due to the large number of valves, the thermal management system occupies a large space and has a low degree of integration, which increases the cost of the thermal management system and the difficulty of control. Summary of the invention

To this end, the first purpose of the present application is to propose a multi-way valve, which has a high degree of integrated design to reduce the cost and control difficulty of the integrated module and the thermal management system, and solves the technical problems in the prior art that the thermal management system uses multiple valves, resulting in a large space occupation, low degree of integration, high cost and high control difficulty.

[0008] In the technical solution of the embodiment of the present application, five valve ports are arranged on the valve body, and a first connecting port, a second connecting port, an adjusting connecting port and a switching connecting port are arranged on the outer peripheral wall of the valve core, and a first switching flow channel and at least one second switching flow channel are arranged inside the valve core, so that the multi-way valve has a switching mode and a proportional adjustment mode at the same time. 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. The multi-way valve is applied to thermal management systems and integrated modules, which 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.

[0052] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0053] The term "plurality" used in the present application refers to two or more (including two).

[0054] Valves are used in thermal management systems. They are mainly used 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 vehicle for the motor, battery or passenger compartment, ensuring the comfort, safety and cruising range of the vehicle.

[0055] However, the applicant has noticed that in order to achieve the connection relationship between different circuits, multiple valves are usually required to be set up, but 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.

[0056] In order to solve the above problems, the embodiment of the present application provides a multi-way valve 1000, and the specific scheme is to set at least five valve ports 110 on the valve body 100, and the valve core 200 is rotatably set on the valve body 100, and the first communication port 211, the second communication port 212, the adjustment communication port 213 and the switching communication port 214 are set on the outer peripheral wall of the valve core 200, and the first switching flow channel 240 and at least one second switching flow channel 250 are set inside the valve core 200, and the first communication port 211 and the second communication port 212 are both set to The first switching flow channel 240 is respectively connected with the regulating connecting port 213, and the first connecting port 211 and the second connecting port 212 can be respectively connected with the corresponding valve port 110, and each second switching flow channel 250 is arranged 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, thereby improving the integration of the multi-way valve 1000 and expanding the adaptability of the multi-way valve 1000.

[0057] The multi-way valve 1000 of the embodiment of the present application is described below with reference to the accompanying drawings.

[0058] Combination Figure 1-Figure 6 As shown, a multi-way valve 1000 according to an embodiment of the present application includes a valve body 100 and a valve core 200 .

[0059] Among them, combined Figure 1 , Figure 2 and Figure 3 As shown, the valve body 100 is provided with at least five valve ports 110. Here, it means that the valve body 100 is provided with five valve ports 110, or more than five valve ports 110, and the valve ports 110 are used to achieve communication between the inside and outside of the multi-way valve 1000, so as to ensure that the external medium can flow into the interior of the multi-way valve 1000 through the valve ports 110, and the external medium flowing into the interior of the multi-way valve 1000 can flow out through the valve ports 110, so as to achieve the transportation of the external medium.

[0060] When different valve ports 110 are connected, switching between multiple modes can be achieved.

[0061] In some embodiments, the valve port 110 is connected to an external pipeline, such as a water pump, a motor cooling pipeline, a battery heating pipeline and a cooling pipeline, a cabin heating pipeline, etc., so that the valve port 110 can be used to discharge the external medium to the external pipeline or the external pipeline can be used to transport the external medium to the multi-way valve 1000, so that the multi-way valve 1000 can be used to control the flow direction of the external medium.

[0062] It should be noted that the external medium mentioned here can be water, refrigerant or other liquids.

[0063] The valve core 200 is rotatably disposed on the valve body 100, and is combined with Figure 5 , Figure 7 and Fig. 9 As shown, 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, and the interior of the valve core 200 is provided with a first switching flow channel 240 and at least one second switching flow channel 250. 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.

[0064] 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 may be provided with one second switching flow channel 250 or multiple second switching flow channels 250; the first communication port 211 is connected with the regulating communication port 213 through the first switching flow channel 240, and the second communication port 212 is connected with 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 realize the connection 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, and can also connect more than two switching connecting ports 214 to realize the mutual connection 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.

[0065] 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 .

[0066] It should be noted that the communication mentioned here means that the external medium between the two can flow mutually. For example, when the regulating communication port 213 is connected with the first communication port 211 through the first switching flow channel 240, the external medium flowing through the regulating communication port 213 can flow to the first communication port 211 through the first switching flow channel 240, and correspondingly, the external medium flowing through the first communication port 211 can also flow to the regulating communication port 213 through the first switching flow channel 240, so as to realize the flow of the external medium, thereby ensuring the working performance of the thermal management system.

[0067] In a specific example, since the first switching flow channel 240 is used to achieve mutual communication between the regulating connecting port 213 and the first connecting port 211 and to achieve mutual communication between the regulating connecting port 213 and the second connecting port 212, when the external medium enters the valve core 200 through the regulating connecting port 213, the external medium can flow to the first connecting port 211 and the second connecting port 212 at the same time through the first switching flow channel 240. When the first connecting port 211 and the second connecting 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.

[0068] Correspondingly, since the first switching flow channel 240 is used to achieve mutual communication between the regulating connecting port 213 and the first connecting port 211 and to achieve mutual communication between the regulating connecting port 213 and the second connecting port 212, when the external medium enters the valve core 200 through the first connecting port 211 and the second connecting port 212, the external medium can flow to the regulating connecting port 213 through the first switching flow channel 240. When the regulating connecting port 213 is connected with 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.

[0069] 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 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 ports 110, the external medium can be discharged through the valve ports 110, so as to control the flow direction and flow path of the external medium.

[0070] 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, the first communication port 211 and the second communication port 212 are respectively connected to the corresponding valve ports 110, and the communication area between the valve port 110 and the first communication port 211 and the second communication port 212 is changed when the valve core 200 rotates. Here, it means that 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 ports 110 and one of the valve ports 110 is connected to the adjustment communication port 213, so that it can be ensured that the external medium can enter the valve core 200 through at least two valve ports 110 or that the external medium in the valve core 200 can be discharged through at least two valve ports 110, and at the same time, the communication area between the valve port 110 and the first communication port 211 and the second communication port 212 is changed when the valve core 200 rotates, thereby realizing proportional adjustment, so that the multi-way valve 1000 of the present application can have a proportional adjustment function.

[0071] In a specific example, 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 connecting port 213, the external medium can enter the valve core 200 through the regulating connecting port 213 respectively. Since the first connecting port 211 and the second connecting port 212 are both connected to the regulating connecting port 213 through the first switching channel 240, the external medium entering the valve core 200 through the regulating connecting port 213 can flow along the guide path of the first switching channel 240 to the first connecting port 211 and the second connecting port 212. Since the first connecting port 211 and the second connecting 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 connecting port 211 and the second connecting 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.

[0072] 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 valve ports 110 corresponding to 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.

[0073] It should be noted that, when the valve core 200 rotates, the communicating areas between the first communicating port 211 and the second communicating port 212 and the corresponding valve port 110 can be changed, thereby achieving the purpose of proportional regulation.

[0074] The valve core 200 rotates so that two different valve ports 110 are switched and connected through the second switching flow channel 250. That is, when the valve core 200 rotates relative to the valve body 100, the second switching flow channel 250 can be controlled to connect different valve ports 110, thereby realizing switching between multiple modes, so that the multi-way valve 1000 has the function of mode switching, and the adaptability of the multi-way valve 1000 is expanded.

[0075] 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, the multi-way valve 1000 is applied to the thermal management system, which can effectively improve the integration of the thermal management system and reduce the control difficulty and cost of the thermal management system.

[0076] In summary, the multi-way valve 1000 of the present application has a high degree of integration and can simultaneously satisfy the mode switching function and proportional adjustment function of a three-way valve and a four-way valve combined together to meet the needs of the thermal management system and reduce the cost of the thermal management system.

[0077] In a specific example, 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 adjusting 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 adjusting 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 adjusting 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.

[0078] 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, and 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. 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 connecting port 211, the second connecting port 212, the regulating connecting port 213 and the switching connecting port 214 are rotated to be offset from the valve port 110, the first connecting port 211, the second connecting port 212, the regulating connecting port 213 and the switching connecting port 214 are not connected to the valve port 110. At this time, the external medium cannot flow into the first connecting port 211, the second connecting port 212, the regulating connecting port 213 and the switching connecting port 214, and the external medium located in the valve core 200 cannot be discharged either.

[0079] In addition, by changing the overlapping range between the first connecting port 211, the second connecting port 212, the adjusting connecting port 213 and the switching connecting port 214 and the corresponding valve port 110, the connecting area between the first connecting port 211, the second connecting port 212, the adjusting connecting port 213 and the switching connecting port 214 and the corresponding valve port 110 can be changed.

[0080] Specifically, the larger the overlapping range between the first connecting port 211, the second connecting port 212, the adjusting 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 adjusting connecting port 213 and the switching connecting port 214 and the corresponding valve port 110, which facilitates proportional adjustment.

[0081] 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. The multi-way valve 1000 is applied to thermal management systems and integrated modules, which 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.

[0082] 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 and reduce the control difficulty and cost of the thermal management system.

[0083] 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.

[0084] In some embodiments, Figure 4 As shown, the valve body 100 has an open accommodating cavity 120, and the valve core 200 is rotatably disposed 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.

[0085] In some embodiments, in combination Figure 1 , Figure 2 and Figure 4 As shown, the valve body 100 also includes a cover plate 130, which can be 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.

[0086] Optionally, combined Figure 1 , Figure 2 and Figure 4As shown, 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 .

[0087] The fastener 140 mentioned here may be a bolt, a screw, etc.

[0088] In some embodiments, Figure 7 and Figure 8 As shown, 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 communicated through the first switching flow channel 240. That is to say, the external medium flowing through the plurality of regulating communication ports 213 can flow mutually through the first switching flow channel 240, so that the plurality of regulating communication ports 213 can communicate with the first communication port 211 and the second communication port 212 through the first switching flow channel 240, ensuring that the external medium between the plurality of regulating communication ports 213 and the first communication port 211 and the external medium between the plurality of regulating communication ports 213 and the second communication port 212 can flow mutually.

[0089] In addition, by arranging a plurality of regulating connecting ports 213 on the outer peripheral wall of the valve core 200, the plurality of 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, thereby ensuring the accuracy of the flow of the external medium, thereby ensuring the working performance of the multi-way valve 1000.

[0090] In some embodiments, in combination Figure 7 and Fig. 9 As shown, a plurality of switching communication ports 214 are provided on the outer peripheral wall of the valve core 200 , so that the switching communication ports 214 are provided on both the first layer flow channel 260 and the second layer flow channel 270 described below to ensure the working performance of the multi-way valve 1000 .

[0091] In some embodiments, in combination Figure 5 , Figure 7 and Figure 8 As shown, the valve core 200 is provided with a first layer flow channel 260 and a second layer flow channel 270 parallel to the rotation axis of the valve core 200. The first layer flow channel 260 is provided with an adjustment 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. The rotation axis of the valve core 200 mentioned here can be understood as Figure 5The axis of the middle driving matching part 221, that is, in the extension direction of the axis of the driving 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, 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 first connecting port 211, the second connecting port 212, the adjusting connecting port 213 and the switching connecting port 214 being set 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.

[0092] 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 connecting ports on the two layers of flow channels can be connected.

[0093] In some embodiments, in combination Figure 5 , Figure 7 and Figure 8 As shown, the first layer flow channel 260 is provided with a plurality of regulating communication ports 213 , so that a plurality of regulating communication ports 213 are provided on the valve core 200 , thereby ensuring the working performance of the multi-way valve 1000 .

[0094] In some embodiments, in combination Figure 5 , Figure 7 and Fig. 9 As shown, 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 connecting ports 214 arranged at circumferential intervals 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 connecting ports 214 arranged at circumferential intervals and connected, and each group of first switching groups 261 is connected with 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 mutually 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 and the integrated module.

[0095] It should be noted that by configuring each first switching group 261 and each second switching group 271 to include at least two switching connecting ports 214 that are circumferentially spaced and connected, so that the switching connecting ports 214 can be independent of each other, it is convenient to achieve the coordination between the switching connecting ports 214 and the valve ports 110, so that the switching connecting ports 214 and the valve ports 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.

[0096] In a specific example, since each group of first switching groups 261 is connected to a group of second switching groups 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.

[0097] 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 connecting 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.

[0098] It should be noted that, for the convenience of description, Figure 7 , Figure 8 and Fig.12 As shown, two switching communication ports 214 in one of the first switching groups 261 on the first layer flow channel 260 are defined as port a and port b; and two switching communication 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.

[0099] Accordingly, combined Fig. 9 and Fig.13 As shown, two switching communication ports 214 in one group of the second switching groups 271 on the second layer flow channel 270 are defined as port A and port H; and two switching communication ports 214 in another group of the second switching groups 271 on the second layer flow channel 270 are defined as port D and port E.

[0100] Among them, combined Figure 5 , Fig.12 and Fig.13 As shown, in the extension direction of the rotation axis of the valve core 200 , the port a on the first layer flow channel 260 faces the port A on the second layer flow channel 270 ; the port d on the first layer flow channel 260 faces the port D on the second layer flow channel 270 .

[0101] In some embodiments, in combination Figure 5 and Figure 7 As shown, the valve core 200 is formed into a cylindrical shape, and the regulating communication port 213 and the two groups of first switching groups 261 are arranged sequentially in the circumferential direction of the valve core 200. The valve core 200 is set into a cylindrical shape so as to realize the rotational coordination of the valve core 200 and the valve body 100, and reduce the difficulty of rotating the valve core 200. When the external medium flows in the valve core 200, the resistance of the valve core 200 to the external medium can also be reduced, thereby reducing the pressure drop and flow loss of the external medium, and ensuring the performance of the multi-way valve 1000; by arranging the regulating communication port 213 and the two groups of first switching groups 261 sequentially in the circumferential direction of the valve core 200, the space on the valve core 200 can be rationally utilized, ensuring that the valve core 200 can be provided with the regulating communication port 213 and the two groups of first switching groups 261 at the same time, thereby ensuring that the valve core 200 can control the multi-way valve 1000 to switch between multiple modes when the valve core 200 rotates.

[0102] 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 the first layer flow channel 260 is provided with multiple regulating connecting ports 213 and multiple switching connecting ports 214.

[0103] Optionally, combined Figure 5 and Fig. 9 As shown, 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 the first connecting port 211, the 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 the first connecting port 211, the second connecting port 212, a plurality of adjusting connecting ports 213 and a plurality of switching connecting ports 214.

[0104] In some embodiments, in combination Figure 1 , Figure 2 and Figure 3 As shown, at least five valve ports 110 are arranged on the same side wall of the valve body 100, and the side wall is arranged parallel to the rotation axis of the valve core 200. In other words, at least five valve ports 110 are arranged on the side wall of the valve body 100 arranged parallel to the rotation axis of the valve core 200, so that it is easy to realize the communication between the valve port 110 and the first communication port 211, the second communication port 212, the adjustment communication port 213 and the switching communication port 214, and the difficulty of molding multiple valve ports 110 can also be reduced.

[0105] In some embodiments, in combination Figure 2 and Figure 3As shown, at least five valve ports 110 are provided on the bottom wall 150 of the valve body 100. At least five valve ports 110 are provided on the side wall of the valve body 100 which is parallel to the rotation axis of the valve core 200, and the valve ports 110 are formed on the bottom surface of the valve body 100. On the one hand, the difficulty of forming the valve ports 110 can be reduced, and on the other hand, the difficulty of matching 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 can be reduced. At the same time, water inlet and outlet can be achieved at the same end of the multi-way valve 1000, which further simplifies the structure of the multi-way valve 1000, and can make the volume of the multi-way valve 1000 smaller and easier to control.

[0106] In other words, the multi-way valve 1000 of the present application has a compact structure and is easy to control.

[0107] In some embodiments, in combination Figure 2 and Figure 3 As shown, at least five valve ports 110 include two rows of valve ports 110, and the two rows of valve ports 110 are arranged in sequence in the extension direction of the rotation axis of the valve core 200, wherein 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, and 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 extension direction of the rotation axis of the valve core 200. This is to facilitate the switching function and the proportional adjustment function of the multi-way valve 1000 and improve the integration of the multi-way valve 1000.

[0108] 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.

[0109] For example: Figure 3 As shown, 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.

[0110] In some embodiments, in combination Figure 1 , Figure 3 and Figure 4As shown, the side wall of the accommodating cavity 120 of the valve body 100 is provided with an avoidance port 121 connected to the valve port 110, and the avoidance 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 controlling the flow direction of the external medium using the multi-way valve 1000.

[0111] Optionally, combined Figure 1 , Figure 3 and Figure 4 As shown, 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.

[0112] Alternatively, if Figure 4 As shown, 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 .

[0113] That is to say, five avoidance openings 121 are formed on the side wall of the accommodating chamber 120 , two of which are formed in a row at one end of the accommodating chamber 120 in the axial direction, and the other three avoidance openings 121 are formed in a row at the other end of the accommodating chamber 120 in the axial direction.

[0114] Optionally, two of the avoidance ports 121 face the first layer flow channel 260, and are used to cooperate with multiple regulating connecting ports 213 and multiple switching connecting 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 connecting port 211, the second connecting port 212 and the multiple switching connecting 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 connecting port 211, the second connecting port 212 and the multiple switching connecting 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 connecting ports 213 and the multiple switching connecting ports 214 on the first layer flow channel 260.

[0115] In some embodiments, in combination Figure 7 and Figure 8As shown, the first switching flow channel 240 includes a communication flow channel 241, a first flow channel 242 and a second flow channel 243, and the communication flow channel 241 is used to communicate with the regulating communication port 213. This is to achieve the communication between the regulating communication port 213 and the first switching flow channel 240, ensuring that the external medium flowing through the regulating communication port 213 can flow to the first switching flow channel 240, and correspondingly, it can also be ensured that the external medium flowing through the first switching flow channel 240 can flow to the regulating communication port 213.

[0116] It should be noted that, for the convenience of description, Figure 7 , Figure 8 and Fig.12 As shown, the plurality of regulating communication ports 213 are respectively defined as port e, port f, port g, and port h.

[0117] Among them, combined Figure 5 , Fig.12 and Fig.13 As shown, 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 .

[0118] Optionally, combined Figure 7 and Figure 8 As shown, the first flow channel 242 and the second flow channel 243 are arranged at intervals, 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 realizing the expansion of the adaptability of the multi-way valve 1000.

[0119] In some embodiments, in combination Figure 7 , Figure 8 and Fig. 9As shown, the first flow channel 242 includes a middle flow channel 2421 located in the center, the middle flow channel 2421 is connected to the connecting flow channel 241, and the second flow channel 243 is located outside the middle flow channel 2421. In this way, while ensuring that the first flow channel 242 can connect the connecting flow channel 241 and the first connecting port 211, and the second flow channel 243 can connect the connecting flow channel 241 and the second connecting port 212, it is also possible to rationally utilize the space in the valve core 200 to ensure that the connecting flow channel 241, the first flow channel 242 and the second flow channel 243 can be arranged in the valve core 200, and also to enable the multi-way valve 1000 to have a proportional adjustment mode, enriching the functions of the multi-way valve 1000.

[0120] It should be noted that, for the convenience of description, Figure 7 , Figure 8 and Fig.12 As shown, the first communication port 211 is defined as the B port; and the second communication port 212 is defined as the G port.

[0121] Among them, combined Figure 5 , Fig.12 and Fig.13 As shown, 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 .

[0122] Optionally, combined Figure 5 , Figure 7 and Fig.13 As shown, two sealing plates 272 are further provided on the peripheral wall of the second layer flow channel 270, one of the sealing plates 272 is located between the B port and the D port, and the other sealing plate 272 is located between the E port and the G port. When the sealing plate 272 is facing the valve port 110, the external medium 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.

[0123] Among them, combined Figure 5 , Fig.12 and Fig.13 As shown, in the extension direction of the rotation axis of the valve core 200, the sealing 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 sealing 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.

[0124] In summary, combined Fig.12 and Fig.13As shown, the first layer flow channel 260 has a port a, b port, c port, d port, e port, f port, g port and h port formed on the peripheral wall in sequence; the second layer flow channel 270 has A port, B port, blocking plate 272, D port, E port, blocking plate 272, G port and H port formed on the peripheral wall in sequence. In the extension direction of the rotation axis of the valve core 200, the a port faces the A port, the b port faces the B port, the c port faces the blocking plate 272, the d port faces the D port, the e port faces the E port, the f port faces the blocking plate 272, the g port faces the G port, and the h port faces the H port.

[0125] 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.

[0126] Through the above configuration, the multi-way valve 1000 can have multiple modes to expand the adaptability of the multi-way valve 1000.

[0127] In a specific example, Fig.14 As shown, 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. Fig.14 The a port on the first layer flow channel 260 is opposite to the position between the fourth valve port 114 and the fifth valve port 115, which can be understood as the A 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 G port on the second layer flow channel 270, the second valve port 112 is opposite to the A port on the second layer flow channel 270, the third valve port 113 is opposite to the blocking plate 272 located between the B port and the D port on the second layer flow channel 270, the fourth valve port 114 is opposite to the h port on the first layer flow channel 260, and the fifth valve port 115 is opposite to the b port on the first layer flow channel 260.

[0128] At this time, 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. When the external medium enters the valve core 200 from the port b and the port h on the first layer flow channel 260, because 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 faces 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 the b port; because the h port 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 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 not connected to the valve port 110, the G port is opposite to the first valve port 111. At this time, the external medium entering the valve core 200 through the h 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 through the h port to realize the first working mode of the multi-way valve 1000.

[0129] like Fig.15 As shown, 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, so that Fig.15 The h port on the first layer flow channel 260 is opposite to the position between the fourth valve port 114 and the fifth valve port 115. It can be understood that the H port on the second layer flow channel 270 is opposite to the second valve port 112. That is to say, the first valve port 111 is blocked by the blocking 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.

[0130] At this time, the external medium can enter the valve core 200 from the a port and the g port on the first layer flow channel 260, or enter the valve core 200 from the B port and the H port on the second layer flow channel 270. When the external medium enters the valve core 200 from the a port and the g port on the first layer flow channel 260, because the a port 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 a port can flow toward the A port and the H port on the second layer flow channel 270 through the second switching flow channel 250. Since the A port is not connected to the valve port 110, and the H port is opposite to the second valve port 112, the external medium entering the valve core 200 through the a port 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. Because 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.

[0131] like Fig.16 As shown, in the case of the third working mode, the valve core 200 rotates so that a part of the a port and a part of the b port on the first layer flow channel 260 are connected to the fifth valve port 115 at the same time, a part of the g port and a part of the h port on the first layer flow channel 260 are connected to the fourth valve port 114, a part of the B port on the second layer flow channel 270 is connected to the third valve port 113, and a part of the G port on the second layer flow channel 270 is connected to the first valve port 111, so Fig.16 A portion of the h port and a portion of the a port on the first-layer flow channel 260 are opposite to the position between the fourth valve port 114 and the fifth valve port 115. It can be understood that a portion of the A port and a portion of the H port on the second-layer flow channel 270 are opposite to the second valve port 112, that is, the first valve port 111 is opposite to the G port on the second-layer flow channel 270, the second valve port 112 is opposite to the A port and 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 and the h port on the first-layer flow channel 260, and the fifth valve port 115 is opposite to the a port and the b port on the first-layer flow channel 260.

[0132] At this time, the external medium can enter the valve core 200 from the ports a, b, g, and h on the first layer flow channel 260, or enter the valve core 200 from the ports B, A, H, and G on the second layer flow channel 270. When the external medium enters the valve core 200 from the ports a, b, g, and h on the first layer flow channel 260, because the ports a and 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 ports a and b can flow toward the ports A and H on the second layer flow channel 270 through the second switching flow channel 250, and the ports A and H are directly opposite to the second valve port 112. At this time, the external medium entering the valve core 200 through the ports a and 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 ports a and b. The g port and the h port are the regulating connecting port 213 and connect 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 opposite to the third valve port 113 and the G port is opposite to 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.

[0133] In a specific example, Fig.17 As shown, 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, so Fig.17 The e port on the first layer flow channel 260 is opposite to the position between the fourth valve port 114 and the fifth valve port 115, which 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.

[0134] 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, because 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. Accordingly, 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 with the switching connecting port 214 on the second layer channel 270 through the second switching channel 250, at this time, 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. Because port D is not connected with the valve port 110, port E is opposite to 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.

[0135] In a specific example, Fig.18 As shown, 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. Fig.18 The d port on the first layer flow channel 260 is opposite to the position between the fourth valve port 114 and the fifth valve port 115, which can be understood as 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.

[0136] At this time, 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. 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 directly opposite to 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. Accordingly, 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 with 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. Because port E is not connected with the valve port 110, port D is opposite to 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.

[0137] In a specific example, Fig.19 As shown, in the sixth working mode, the valve core 200 rotates so that a part of the e port and a part of the f port on the first layer flow channel 260 are connected to the fifth valve port 115, a part of the c port and a part of the d port on the first layer flow channel 260 are connected to the fourth valve port 114, a part of the G port on the second layer flow channel 270 is connected to the third valve port 113, and a part of the B port on the second layer flow channel 270 is connected to the first valve port 111, so Fig.19 A portion of the d port and a portion of the e port on the first-layer flow channel 260 are opposite to the position between the fourth valve port 114 and the fifth valve port 115. It can be understood that a portion of the D port and a portion of the E port on the second-layer flow channel 270 are 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 and 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 c port and the d port on the first-layer flow channel 260, and the fifth valve port 115 is opposite to the e port and the f port on the first-layer flow channel 260.

[0138] 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. Among them, when the external medium enters the valve core 200 from the e port and f port on the first layer flow channel 260, because the e port and f port are the regulating connecting ports 213 and are connected to the first connecting port 211 and the second connecting 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 the G port on the second layer flow channel 270 through the first switching flow channel 240. Because 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, and accordingly, enter 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 the e port and the f port; because the c port and the d port are the switching connecting port 214 and are connected with the switching connecting port 214 on the second layer flow channel 270 through the second switching flow channel 250, at this time, the external medium in the c port and the d port can flow toward the D port and the E port on the second layer flow channel 270 through the second switching flow channel 250, because the D port and the E port are both facing the second valve port 112, at this time, the external medium entering the valve core 200 through the c port and the d port can be discharged through the second valve port 112, and accordingly, the external medium entering the valve core 200 through the second valve port 112 can also be discharged through the c port and the d port to realize the sixth working mode of the multi-way valve 1000.

[0139] It should be noted that the above working modes are only examples and do not represent limitations on this application.

[0140] 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, a plurality of adjusting connecting ports 213 and a plurality of switching connecting ports 214 on the outer peripheral 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 the four-way valve combined together.

[0141] in, Fig.14 The first working mode in Fig.15 The second working mode in Fig.17 The fourth working mode in Fig.18 The fifth working mode in is used to play the function of mode switching; Fig.16 The third working mode in Fig.19The sixth working mode is used to perform a proportional regulation function. Compared with the combination of a traditional three-way valve and a four-way valve, the multi-way valve 1000 not only reduces the cost, but also further improves the breadth of its application.

[0142] In some embodiments, Fig.14 As shown, the multi-way valve 1000 further includes a sealing member 300, which is disposed between the valve core 200 and the valve body 100. The sealing connection between the valve core 200 and the valve body 100 is realized, so as to facilitate the sealing 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, thereby ensuring that the external medium can effectively flow between the valve core 200 and the valve body 100, ensuring the flow guiding effect of the multi-way valve 1000, and avoiding the loss of the external medium.

[0143] In some embodiments, the sealing member 300 is formed as a rubber member to ensure the sealing effect of the sealing member 300 .

[0144] 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 arranged in the groove, so that the sealing member 300 is used to realize the sealing connection between the valve core 200 and the valve body 100, and the difficulty of fixing the sealing member 300 is reduced, and the fixing quality is ensured, thereby improving the sealing effect of the sealing member 300 and ensuring the working performance of the multi-way valve 1000.

[0145] In some embodiments, in combination Figure 5 , Figure 7 , Fig. 9 and Fig.11 As shown, the valve core 200 includes a body 210, a first end cover 220 and a second end cover 230, and 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. The first communication port 211, the second communication port 212, the regulating communication port 213 and the switching communication port 214 are formed on the valve core 200, the working performance of the valve core 200 is ensured, and the molding difficulty of the first communication port 211, the second communication port 212, the switching communication port 214 and the regulating communication port 213 is reduced, thereby reducing the molding difficulty of the valve core 200.

[0146] Alternatively, if Fig.11 As shown, 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 .

[0147] Alternatively, if Figure 5 and Fig.11As shown, the first end cover 220 and the second end cover 230 are arranged at both ends of the body 210, the first end cover 220 is provided with a driving matching portion 221, the driving matching portion 221 is suitable for connecting with the driving member, the second end cover 230 is rotatably supported on the valve body 100, and the driving member drives the valve core 200 to rotate. In other words, the first end cover 220 is used to cooperate with the driving member, and the second end cover 230 is used to cooperate with the valve body 100, so as to ensure that the valve core 200 can effectively rotate relative to the valve body 100, so as to ensure the working performance of the multi-way valve 1000.

[0148] 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.

[0149] 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 driving member via the drive fitting portion 221 to achieve a fitting connection between the valve core 200 and the driving member, thereby facilitating the use of the driving member to drive the valve core 200 to rotate, and at the same time can also reduce the difficulty of fitting between the driving member and the valve core 200.

[0150] In some embodiments, Figure 5 and Fig.11 As shown, the driving mating portion 221 is a mating shaft, which is used to be mated and connected with the output end of the driving member to realize the mating 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 realize the use of the driving member to drive the valve core 200 to rotate.

[0151] In addition, the second end cover 230 is rotatably supported on the valve body 100. While the valve core 200 and the valve body 100 are rotatably coordinated, 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.

[0152] In some embodiments, a convex portion 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 convex portion 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 first end cover 220 and the second end cover 230 to be arranged 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.

[0153] 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.

[0154] In a specific example, 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.

[0155] 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.

[0156] In summary, one end of the valve core 200 is rotatably matched with the valve body 100 through the first end cover 220, and the other end of the valve core 200 is rotatably 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.
