Illustratively, each of the water dispensing channels is provided with a solenoid valve, and each solenoid valve is electrically connected to a control component. For example, the first water dispensing channel 200 is provided with a first solenoid valve 8, the second water dispensing channel 300 is provided with a second solenoid valve 9, and the third water dispensing channel 400 is provided with a third solenoid valve 22. When the first solenoid valve 8 is opened, the first water dispensing channel 200 is communicated with the water feeding channel, and cold water is discharged from the water dispensing component 10; when the second solenoid valve 9 is opened, the second water dispensing channel 300 is communicated with the water feeding channel, and hot water is discharged from the water dispensing component 10; and when both the second solenoid valve 9 and the third solenoid valve 22 are opened, the second water dispensing channel 300 and the third water dispensing channel 400 are both communicated with the water feeding channel, and mixed water is discharged from the water dispensing component 10.

It should be noted that, in this embodiment, when the user selects cold water on the human-computer interaction interface of the control component, the control component drives the first water dispensing channel 200 to open, so that clean water flows from the first water dispensing channel 200 to the water dispensing component 10; and when the user selects hot water, the control component drives the second water dispensing channel 300 to open, and the clean water is pumped out by a water pump 17 after being heated by the heat storage tank 19 so as to ensure the water dispensing power. When a user selects mixed water, both the second water dispensing channel 300 and the third water dispensing channel 400 are opened, and a feeding ratio of the cold water to the hot water is adjusted by a hot water flow regulator and a cold water flow regulator 21, so that the temperature adjustment of the mixed water is achieved. In summary, this embodiment has the functions of reverse osmosis filtration, cold water, hot water, and mixed water supply, making it well-suited to meet the users' requirements in different scenarios.

In a preferred embodiment, the water feeding channel includes a filtering line 100, and raw water is filtered by the filtering line 100 to obtain clean water. Specifically, the filtering line 100 is sequentially provided with a switch valve 1, a water feeding valve 2, a booster pump 23, a reverse osmosis filter element 5, a flow meter 6, and a first temperature sensor 7 along a water flow direction. The switch valve 1 is preferably a ball valve, the transmission power of the water flow is ensured by the booster pump 23, the reverse osmosis filter element 5 can be a filter element with an RO reverse osmosis membrane, a waste water channel of the reverse osmosis filter element 5 is provided with a waste water valve 24 and a third one-way valve 25, and the waste water valve 24 is electrically connected to the control component. Of course, in other embodiments, the water feeding channel may not be provided with the filtering line 100, and only a channel with a water feeding function is provided.

Preferably, the filtering line 100 is provided with a backflow line, the backflow line connects to the upstream of the booster pump 23 from the downstream of the reverse osmosis filter element 5, and the backflow line is sequentially provided with a backflow valve 4 and a fourth one-way valve 3 along a water flow direction.

The water feeding valve 2, the waste water valve 24, and the backflow valve 4 are preferably solenoid valves, and may be other electrically controlled valves, which are not limited thereto and are not particularly limited.

Based on the above embodiments, in an optional embodiment of the present application, the hot water flow regulator includes a water pump 17 and a flow meter 16, and the second water dispensing channel 300 is sequentially provided with a heat storage tank 19, the water pump 17, the flow meter 16, and a first one-way valve 14 along a water flow direction. The water flow is measured by the flow meter 16, and the power of the water pump 17 is controlled by the control component, so that hot water with different flow rates is output. A heater 18, a third temperature sensor 20, a high liquid level sensor 12, and a low liquid level sensor 13 are arranged in the heat storage tank 19, a temperature of water in the heat storage tank 19 is monitored by the third temperature sensor 20, and the liquid level in the heat storage tank 19 is monitored by the liquid level sensor to ensure the supply of hot water. In this embodiment, the hot water capacity is increased by providing the heat storage tank 19, and the heating efficiency is improved by using the heater 18, thereby ensuring the flow rate of hot water. An exhaust channel of the heat storage tank 19 is connected to the water dispensing component 10, and hot air in the exhaust channel is exhausted by the water dispensing component 10, so that the structural design of the exhaust channel can be simplified, and the heating safety is ensured.

The third water dispensing channel 400 is sequentially provided with the cold water flow regulator 21 and a second one-way valve along a water flow direction 14. Both the second water dispensing channel 300 and the third water dispensing channel 400 are connected to the water dispensing component 10 by the water dispensing flow path, and the water dispensing flow path is connected to a water dispensing port on the water dispensing component 10, so that the number of lines in the water dispensing component 10 is reduced, and the line space is reduced.
