[0038] The working process of the faucet in this embodiment is as follows:

[0039] When the drinking water device is opened to release water (water release can be controlled by a solenoid valve), water enters the water outlet channel 30 from the water inlet hole 31a and, under the action of the outlet water pressure, pushes open the sealing member 21 in the first state. At this time, the sealing member 21 changes to the second state (the first sealing portion 211 can open the water outlet channel 30. In this embodiment, the first sealing portion 211 can open the water inlet hole 31a, and the second sealing portion 212 can open the water outlet 1a). At the same time, the spring is compressed under the action of the outlet water pressure.

[0040] When the drinking water device is closed to release water (it can be closed by the solenoid valve), the water outlet pressure decreases. At this time, the spring releases energy, thereby pushing the movable rod 214 to move upward, and then the seal 21 in the second state is changed to the first state (the first sealing part 211 blocks the water outlet channel 30, and the second sealing part 212 blocks the water outlet 1a), thereby blocking the water flow and preventing dripping. The double-layer sealing structure of the first sealing part and the second sealing part can improve the sealing effect and effectively prevent dust and bacteria from entering.
