Abstract
A method for shutting off water that is applied to a water outlet device, which comprises enabling a volume of a variable chamber to increase to form a negative pressure chamber to suck residual water in a water outlet chamber into the negative pressure chamber by releasing negative pressure at a connection of the variable chamber and the water outlet chamber when the water is shut off. A method for shutting off water that is applied to a water outlet device, which comprises enabling a water shut-off sealing member to hermetically seal a connection of a water outlet hole and a water outlet chamber by a volume of air in the water outlet chamber of the water outlet device increasing to generate negative pressure when the water is shut off. A water outlet device is provided.
