[0007] The switch assembly is arranged at the water inlet, and is used to unidirectionally open the water inlet when water is flowing in, and to close the water inlet when water is stopped flowing in.

[0008] Beneficial effect: When taking water, water enters the water outlet cavity of the water outlet from the water inlet pipe of the drinking water device through the one-way switch assembly at the water inlet, and then flows out through the water outlet of the water outlet and finally reaches the user's water container; when the user stops taking water, the water inlet pipe stops taking water, the switch assembly is closed, and the area of ​​the flow cross section of the water outlet is less than or equal to 28mm 2 , which is a smaller water outlet, can achieve a water sealing effect when the switch component is closed, so that the entire water outlet cavity forms a sealed state where air cannot enter, and the remaining water in the water outlet cavity will not leak out through the water outlet of the water outlet nozzle, so that the water flow is immediately interrupted after the water is stopped, and there will be no continued dripping or leakage, thereby improving the user experience. Therefore, due to the setting of the switch component and the smaller water outlet, the normal use of the water outlet nozzle can be guaranteed when water is taken, and the water flow can be immediately interrupted after the water is stopped, avoiding continued dripping and leakage.
