The plurality of washing machines share one detergent feeding device, and each washing machine does not need to be provided with a detergent feeding device. The present application realizes one valve for multiple uses, has a simple structure, occupies a small space, and reduces the cost. In addition, the plurality of liquid outlets 12 are arranged on the side of the switching valve in the circumferential direction, the liquid inlet 11 is arranged on the side of the switching valve, and the liquid inlet 11 is arranged away from the center of the end of the switching valve. When the switching valve is in operation, the detergent can be conveniently fed from the liquid inlet 11 arranged away from the center of the end of the switching valve to the liquid outlet 12 of the switching valve, and the feeding path is smooth.

The structure is simple, and the operation control is simple.

[0058] By arranging the liquid inlet 11 on one side away from the rotation axis 3 of the valve core 2, the centrifugal force generated during the rotation of the valve core 2 can be prevented, and the detergent or water is prevented from flowing into the valve body 1 from the liquid inlet 11.

[0059] The outer peripheral wall of the valve core 2 can be rotatably and sealingly connected with part of the inner peripheral wall of the valve body 1, or can be rotatably and sealingly connected with the entire inner peripheral wall of the valve body 1.
