Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0028] As shown in Figures 1 to 5 The present embodiment provides a multi-way valve, which comprises a housing and a valve core 10. The housing has a receiving cavity, and an inlet, a first outlet, a second outlet and a third outlet are arranged on the side wall of the housing in an array. The inlet and the second outlet are located in one row, and the first outlet and the third outlet are located in another row. The valve core 10 is rotatably arranged in the receiving cavity, and a plurality of communication structures are arranged on the valve core 10. The plurality of communication structures are arranged on the valve core 10 in a circumferential direction. Each communication structure comprises an inlet cavity, a first chamber, a second chamber and a third chamber. The inlet cavity is matched with the inlet, the first chamber is matched with the first outlet, the second chamber is matched with the second outlet, and the third chamber is matched with the third outlet. The valve core 10 communicates the inlet with the first outlet, the second outlet and the third outlet through the plurality of communication structures.

The inlet cavity of each communication structure is matched with the inlet on the housing. The first chamber of the communication structure is matched with the first outlet. The second chamber of the communication structure is matched with the second outlet. The third chamber of the communication structure is matched with the third outlet. The valve core 10 communicates the inlet with the first outlet, the second outlet and the third outlet through the communication structures. According to the above scheme, the communication structure can communicate the inlet with the third outlet, so as to realize the flow-through mode of fluid flowing into the inlet and flowing out of the third outlet, thereby increasing the flow-through mode of the multi-way valve and expanding the use range of the multi-way valve.

[0030] Specifically, the inlet and the third outlet are diagonally arranged, and the inlet cavity and the third chamber are diagonally arranged.

[0031] Specifically, the multi-way valve further comprises a sealing gasket 50 arranged between the valve core 10 and the housing.

A second chamber 213 of the first communication structure is in communication with the inlet chamber 211 of the first communication structure, a third chamber 214 of the first communication structure is in communication with the second chamber 213 of the first communication structure. The valve core 10 further includes a first partition plate 30, the first partition plate 30 is arranged in the second chamber 213 of the first communication structure and located between the second chamber 213 of the first communication structure and the second outlet, so as to cut off the second chamber 213 of the first communication structure from the second outlet. The first chamber 212 of the first communication structure is independent of the inlet chamber 211 of the first communication structure, so that the inlet is not in communication with the first outlet. The second chamber 213 of the first communication structure is in communication with the inlet chamber 211 of the first communication structure, and the third chamber 214 of the first communication structure is in communication with the second chamber 213 of the first communication structure, so that the inlet is in communication with the second chamber 213 of the first communication structure and the third chamber 214 of the first communication structure.
