Abstract

A water stopping mechanism configured for a water outlet device comprises one or more pad members configured for elastic deformation. The one or more pad members are configured to be movably disposed in a water outlet chamber of the water outlet device. The one or more pad members at least define a position-providing space, and the one or more pad members comprise a water stopping position and an open position. When in the water stopping position, the one or more pad members elastically hermetically seal and abut an outer peripheral of one or more water outlet ports of the water outlet chamber to achieve water stopping and hermetical sealing, and the one or more pad members are configured to move toward the position-providing space due to increasing of water pressure in the water outlet chamber to terminate the water stopping and the hermetical sealing.

First claim
