It should be noted that, when tap water is used as a water source, the third check valve 506 at the third water inlet 503 connected to the tap water is opened, and a larger opening pressure value may be set for the water inlet check valve of the channel due to a larger water pressure of the inlet water; when the water tank 20 is used as a water source, and the inlet water in the channel of the first water inlet 501 connected to the water tank 20 has almost no water pressure, the inlet water check valve of the channel is set to a smaller opening pressure value; when the external water pool is used as a water source, the water pump 30 is connected to the second water inlet 502 through the second liquid conveying pipe 53, and since the water outlet end of the water pump 30 also has a certain water pressure, the opening pressure value of the check valve of the water inlet channel can be set between the opening pressure values of the check valves at the first water inlet 501 and the third water inlet 503. And when the water from the first water inlet 501, the second water inlet 502 and the third water inlet 503 enters the central chamber of the multi-channel adapter 50, the check valves on the other water inlet channels are automatically closed under the action of the check valve springs and the water pressure of the water, and at the moment, the water flow of the water can stably supply water to the motor pump assembly.
