The water purification waterway according to claim 1, wherein a liquid level sensor is provided in the water storage container, and the liquid level sensor is used to detect the water level in the water storage container.
The water purification waterway according to claim 1, wherein a water quality sensor is provided in the water storage container, and the water quality sensor is used to detect the water quality in the water storage container.
The water purification waterway according to claim 1, wherein a sterilization module is provided in the water storage container.
A water purification method, characterized in that, applied to the water purification waterway as claimed in any one of claims 1 to 10, the method comprising:

The water from the water source flows to the water inlet of the first water purification component through the water flow control unit, so that the first water purification component performs the first purification treatment on the water entering from the water inlet, and outputs the purified water from the water outlet to the storage the first water inlet of the water container;

When the water volume in the water storage container meets the preset water volume, the water flow control unit stops the flow of water from the water source to the water inlet of the first water purification component, and the water flow control unit controls the water flow in the water storage container. The water flows from the water outlet of the water storage container to the water inlet of the second water purification component, so that the second water purification component performs the second purification treatment on the water entering from the water inlet, and the water after the second purification treatment is discharged from the water outlet. The second water inlet is transported to the water storage container, and the waste water generated by the second purification process flows to the water outlet of the first water purification assembly through the waste water port, so as to backwash the first water purification assembly;

When the water quality in the water storage container meets the preset water quality, the water flow control unit stops the water in the water storage container from flowing from the water outlet of the water storage container to the water inlet of the second water purification component.
A water purification device, characterized in that it comprises the water purification waterway according to any one of claims 1 to 10.
