[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative work are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, embodiment 1 of the present invention provides a valve core component, including: an inner cylinder structure 10, the inner cylinder structure 10 has a circulation channel 11 extending along its axial direction, and the side wall of the inner cylinder structure 10 has a first through hole 12 and a second through hole 13 connected to the circulation channel 11; an outer cylinder structure 20, surrounding the inner cylinder structure 10, the outer cylinder structure 20 has a multi-layer circulation cavity 21 along the axial direction of the inner cylinder structure 10, each layer of the circulation cavity 21 is divided into a plurality of sub-cavities along the circumference of the inner cylinder structure 10, and the opening of each sub-cavity is facing the outside of the valve core component; wherein, the first through hole 12 is connected to a sub-cavity in one layer of the circulation cavity 21, and the second through hole 13 is connected to a sub-cavity in another layer of the circulation cavity 21.

[0026] In this embodiment, the multiple layers of flow cavities 21 on the outer cylindrical structure 20 and the multiple subcavities within each flow cavity 21 enable communication between two adjacent subcavities within the same flow cavity 21, or between two adjacent subcavities within two adjacent flow cavities 21, thereby enabling communication between adjacent valve ports 51 of the multi-way valve. The first through hole 12 communicates with a subcavity within one flow cavity 21, and the second through hole 13 communicates with a subcavity within another flow cavity 21, thereby enabling communication between the two subcavities of the two flow cavities 21 through the flow channel 11. If the two flow cavities 21 are adjacent, communication between the two subcavities within the two adjacent flow cavities 21 is achieved, thereby enabling communication between adjacent valve ports 51 of the multi-way valve. If the two flow cavities 21 are spaced apart, communication between the two subcavities within the spaced-apart flow cavities 21 is achieved, thereby enabling communication across the valve ports 51 of the multi-way valve. This arrangement enables communication between the inner cylinder structure 10 and the outer cylinder structure 20 through the first through hole 12, the flow channel 11, and the second through hole 13 of the inner cylinder structure 10. Furthermore, cross-layer communication of the multi-layer flow cavity 21 of the valve core component is achieved through the inner cylinder structure 10, thereby improving the performance and applicability of the valve core component. Multi-layer means at least two layers, and multiple means at least two layers.

[0027] like Figure 1 As shown, the outer cylinder structure 20 has at least three layers of flow cavities 21. In the axial direction of the inner cylinder structure 10, at least one layer of flow cavities 21 is spaced between the first through-hole 12 and the second through-hole 13. This arrangement enables communication between the first layer of flow cavities 21 and the third layer of flow cavities 21 via the first through-hole 12, the flow channel 11, and the second through-hole 13, thereby achieving communication across the valve port 51 of the multi-way valve, improving the performance and applicability of the valve core component.

[0028] Specifically, the outer cylinder structure 20 has four layers of circulation cavities 21. In the axial direction of the inner cylinder structure 10, two layers of circulation cavities 21 are spaced between the first through-hole 12 and the second through-hole 13. This arrangement enables communication between the first and fourth layers of circulation cavities 21 via the first through-hole 12, the circulation channel 11, and the second through-hole 13, thereby achieving cross-valve port 51 communication in the multi-way valve, improving the performance and applicability of the valve core component. Alternatively, communication between the first and third layers of circulation cavities 21, or between the second and fourth layers of circulation cavities 21, can also be achieved via the first through-hole 12, the circulation channel 11, and the second through-hole 13, further improving the performance and applicability of the valve core component.

[0029] Furthermore, the inner cylinder structure 10 includes an inner cylinder body 14, a rotating shaft structure 15 and a plurality of support plates 16. The rotating shaft structure 15 passes through the inner cylinder body 14. The two ends of the support plate 16 are respectively connected to the outer wall of the rotating shaft structure 15 and the inner wall of the inner cylinder body 14. The plurality of support plates 16 are distributed along the circumference of the inner cylinder body 14. The outer cylinder structure 20 surrounds the inner cylinder body 14. The circulation channel 11 is located between the inner cylinder body 14, the rotating shaft structure 15 and two adjacent support plates 16. The first through hole 12 and the second through hole 13 are both located in the inner cylinder body 14.

[0030] In this embodiment, the provision of a rotating shaft structure 15 allows the inner cylinder 14 to rotate with the rotating shaft structure 15, achieving rotation of the entire valve core component, thereby adjusting the communication status of the valve port 51 of the multi-way valve and ensuring the reliability of the valve core component. The provision of multiple support plates 16 enhances the connection strength between the inner cylinder 14 and the rotating shaft structure 15, thereby enhancing the structural strength of the inner cylinder structure 10. Specifically, the first through hole 12 and the second through hole 13 are both located on the outer wall of the inner cylinder 14 and communicate with the flow chamber 21 of the outer cylinder structure 20, thereby achieving communication between the flow chamber 21 and the flow channel 11.

[0031] like Figure 1 As shown, the outer cylinder structure 20 includes a plurality of radial partitions 22 and a plurality of axial partitions 23. The radial partitions 22 are arranged along the radial direction of the inner cylinder structure 10, and the axial partitions 23 are arranged along the axial direction of the inner cylinder structure 10. The plurality of radial partitions 22 are distributed at intervals along the axial direction of the inner cylinder structure 10, and the area between two adjacent radial partitions 22 forms a layer of flow cavity 21. The plurality of axial partitions 23 are distributed at intervals along the circumference of the inner cylinder structure 10 to divide the flow cavity 21 into a plurality of sub-cavities.

[0032] In this embodiment, the outer cylinder structure 20 of the valve core structure is layered by providing multiple radial partitions 22, thereby dividing the area within the outer cylinder structure 20 into multiple layers of flow chambers 21. Each layer of flow chamber 21 is then divided into multiple sub-chambers by multiple axial partitions 23. This arrangement allows the rotation of the shaft structure 15 to drive the rotation of the inner cylinder 14 and the outer cylinder structure 20, achieving circumferential conversion of the multiple sub-chambers on the outer cylinder structure 20, thereby adjusting the connectivity of the valve port 51 of the multi-way valve and ensuring the reliability of the valve core component.

[0033] Specifically, the valve core component is an integrated structure, which facilitates the processing of the valve core component and improves processing efficiency.

[0034] like Figures 2 to 5As shown, embodiment 2 of the present invention provides a valve core component, which is different from the above embodiment in that the valve core component includes a first valve core 30 and a second valve core 40 that can rotate relative to each other, the first valve core 30 includes a first inner cylinder 31 and a first outer cylinder 32 arranged around the first inner cylinder 31, the second valve core 40 includes a second inner cylinder 41 and a second outer cylinder 42 arranged around the second inner cylinder 41, the first inner cylinder 31 and the second inner cylinder 41 are connected to form an inner cylinder structure 10, and the first outer cylinder 32 and the second outer cylinder 42 form an outer cylinder structure 20; wherein, the first inner cylinder 31 has a first channel 111 and a first through hole 12, the second inner cylinder 41 has a second channel 112 and a second through hole 13, the first channel 111 and the second channel 112 are connected to form a circulation channel 11, the first outer cylinder 32 has at least one layer of circulation cavity 21, the second outer cylinder 42 has at least one layer of circulation cavity 21, the first through hole 12 is connected to a circulation cavity 21 of the first outer cylinder 32, and the second through hole 13 is connected to a circulation cavity 21 of the second outer cylinder 42.

[0035] In this embodiment, the valve core component is divided into a first valve core 30 and a second valve core 40. The first valve core 30 and the second valve core 40 have a multi-layer circulation cavity 21. The relative positions of the first outer tube 32 and the second outer tube 42 and the connectivity of the sub-cavities therein enable communication between two adjacent sub-cavities. In particular, the two adjacent sub-cavities are both located in the first outer tube 32, or both adjacent sub-cavities are located in the second outer tube 42, or one sub-cavity is located in the first outer tube 32 and the other adjacent sub-cavity is located in the second outer tube 42, thereby achieving communication between adjacent valve ports 51 of the multi-way valve. Furthermore, the first through hole 12 and the second through hole 13 are connected by the connection between the first channel 111 provided on the first valve core 30 and the second channel 112 provided on the second valve core 40, thereby achieving communication between a sub-cavity of the first valve core 30 and a sub-cavity of the second valve core 40. This arrangement can achieve communication between the sub-cavities of two adjacent circulation cavities 21 as well as communication between two sub-cavities across a circulation cavity 21. Specifically, the first valve core 30 and the second valve core 40 have the same radial size and are arranged end to end in correspondence.

[0036] like Figures 3 to 5As shown, the first inner cylinder 31 includes a first cylinder 311, a first rotating shaft 312 and a plurality of first sub-plates 313, the first rotating shaft 312 passes through the first cylinder 311, and the two ends of the first sub-plate 313 are respectively connected to the outer wall of the first rotating shaft 312 and the inner wall of the first cylinder 311, the first through hole 12 is provided on the first cylinder 311, and the first channel 111 is located between the first cylinder 311, the first rotating shaft 312 and two adjacent first sub-plates 313; the second inner cylinder 41 includes a second cylinder 411, a second rotating shaft 412 and a plurality of second sub-plates 413, the second rotating shaft 412 passes through the second cylinder 411 and the first rotating shaft 312, and the two ends of the second sub-plate 413 are respectively connected to the outer wall of the second rotating shaft 412 and the inner wall of the second cylinder 411, the second through hole 13 is provided on the second cylinder 411, and the second channel 112 is located between the second cylinder 411, the second rotating shaft 412 and two adjacent second sub-plates 413.

[0037] In this embodiment, the connection strength between the first cylinder 311 and the first rotating shaft 312 is enhanced by the multiple first sub-plates 313, thereby enhancing the structural strength of the first inner cylinder 31 and the reliability of the first valve core 30. The connection strength between the second cylinder 411 and the second rotating shaft 412 is enhanced by the multiple second sub-plates 413, thereby enhancing the structural strength of the second inner cylinder 41 and the reliability of the second valve core 40. Specifically, the first cylinder 311 and the second cylinder 411 can both rotate independently, allowing for more variations in the relative positions of the first valve core 30 and the second valve core 40, improving the adjustability of the connectivity between all sub-cavities of the first valve core 30 and the second valve core 40, and expanding the applicability of the valve core component.

[0038] like Figure 6 As shown, embodiment 3 of the present invention provides a multi-way valve, which includes the above-mentioned valve core component.

[0039] Specifically, the valve core component has N layers of flow chambers 21, and the multi-way valve also includes a valve body 50 and an actuator 60. The valve body 50 has 2N valve ports 51. The valve core component is rotatably arranged in the cavity of the valve body 50, and each layer of flow chamber 21 corresponds to two valve ports 51. The actuator 60 and the valve core component are driven and connected.

[0040] In this embodiment, the valve ports 51 on the valve body 50 are connected through the rotation of the valve core component. The outer cylinder structure primarily regulates the flow between any two adjacent valve ports 51 among the 2N valve ports 51, while the inner cylinder structure primarily regulates the flow between any two alternate rows of valve ports 51 within the N rows of valve ports 51. This improves the multi-way valve's adjustable performance and applicability. Specifically, in this embodiment, N = 4, resulting in eight valve ports 51 arranged in two rows and four columns, each corresponding one-to-one to the four layers of flow chambers 21.

[0041] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
