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.

Claims (65)

1 . A water stopping mechanism configured for a water outlet device, comprising:

one or more pad members configured for an elastic deformation, wherein:

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,

the one or more pad members comprise a water stopping position and an open position,

each of the one or more pad members comprises a pad body, and

when in the water stopping position:

the pad body of each of the one or more pad members elastically hermetically seals and abuts an outer peripheral wall of a corresponding one of one or more water outlet ports of the water outlet chamber to achieve water stopping and hermetical sealing, and

when water flows out of the water stopping mechanism:

at least some of the water flows out of a flow passage between the pad body of each of the one or more pad members and the outer peripheral wall of the corresponding one of the one or more water outlet ports of the water outlet chamber, 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 so as to move from the water stopping position to the open position, and the one or more pad members elastically deform to accumulate an elastic force.

2 . The water stopping mechanism configured for the water outlet device according to claim 1 , wherein:

the water stopping mechanism further comprises one or more ventilation holes,

the one or more ventilation holes are in communication with the position-providing space and outside air, and
