As shown in fig. 5 and fig. 6, in the present embodiment, a check valve is disposed on each water inlet path, and the valve can only be opened from the water inlet end of the water inlet pipeline to the water inlet pipeline of the pump in a one-way manner, that is, a check valve is disposed at each water inlet. Specifically, a first check valve 504 is arranged at the first water inlet 501, a second check valve 505 is arranged at the second water inlet 502, a third check valve 506 is arranged at the third water inlet 503, and the first check valve 504, the second check valve 505 and the third check valve 506 are provided with different opening pressure values, so that when different water sources are used, the corresponding check valves are opened, and the other check valves are closed, so as to ensure that when the cleaning machine works with different water sources, the water inlet works from different water inlets are not interfered with each other. 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.

As shown in fig. 6, in some embodiments, an exhaust valve 507 is further installed in the second water inlet 502 of the multi-channel adapter 50 connected to the water pump 30, that is, two check valves are installed at the position where the multi-channel adapter 50 is connected to the second water inlet 502 of the water pump 30, one check valve is used for exhausting air and used as the exhaust valve 507, and the other check valve is used for supplying water and used as the second check valve 506. When the exhaust valve 507 does not form stable water flow, the exhaust valve 507 is in an open state, the inside of the valve is communicated with the outside, when gas flows in the inside, the gas can be quickly discharged from the inside, and when the exhaust is finished, the stable water flow can push the exhaust valve 507 to be closed, so that the water flow enters the motor pump assembly 40. It should be noted that the water pump 30 can also connect the water inlet of the water outlet motor pump assembly 40 to directly supply water to the cleaning machine through a liquid conveying pipeline, in order to solve the problem of air exhaust of the water pipe, an air exhaust valve 507 is further designed between the water outlet of the water pump 30 and the water inlet of the multi-channel adapter 50, the air exhaust valve 507 can exhaust air in the water pumping pipeline out of the pipeline, and meanwhile, the water pump 30 forms initial water pressure in the water pumping process, so that water in the pond can directly enter the high pressure water pump more quickly.

Specifically, when the water pump 30 is used for supplying water, because the water pump 30 pumps water, air in a longer water inlet pipeline enters a pipeline between the water pump 30 and the multi-channel adapter 50 through the water pump 30, and because a user generally does not perform exhaust treatment on the pump and a water outlet pipe when using the water pump, in order to prevent the air in the water inlet pipeline from entering the water outlet pipeline again and needing a long time to be discharged outside a water gun nozzle, particularly, the second water inlet 502 of the pump is provided with the exhaust valve 507, so that the air entering the pipeline can be discharged to the atmosphere through the exhaust valve 507, after the air in the pipeline is completely discharged, water flow entering the channel through the water pump 30 forms water inlet pressure, so that the water inlet one-way valve of the multi-channel adapter 50 is opened to form stable water inlet flow, the exhaust valve 507 can also discharge the air in a long water inlet pipeline between the water inlet end of the water pump 30 and a water source in time, the air exhaust time of the motor pump assembly 40 is shortened, and the high-pressure water outlet time of the motor pump assembly 40 is shortened. The water pump 30 is preferably a direct-flow diaphragm pump, the water pressure of the water output from the water pump 30 is 0.3-1.0MPa, the flow rate is 3-5L/min, and different force values are set in the first check valve 504 and the second check valve 505, so that the second check valve 505 is prevented from being opened by mistake when water enters the water tank 20. And the flow rate of the water pump 30 is equivalent to the high-pressure water outlet flow rate of the cleaning machine, so that the water inlet flow can be stably supplied to the cleaning machine, and meanwhile, when the water pump 30 supplies water to the water tank 20, the water flow of the water tank 20 can be ensured not to be interrupted and not to overflow.
