[0034] The embodiment is described in the initial state of sealing, in which state the parts of the driving piece 2 and the driven piece 3 located in the shell 1 are close to each other, and the magnet one 24 and the magnet two 36 correspondingly generate a large attractive force to maintain a state of having a tendency to approach each other, at the same time, the parts of the driving piece 2 and the driven piece 3 located outside the shell 1 are tightly attached to both ends of the shell 1, and the water outlet one 12 and the water outlet two 13 are sealed; when opening is needed, the position of the magnet one 24 is changed by rotating the driving piece 2, so that the position of the magnet one 24 corresponds to the magnet three 37, in this state, the magnet one 24 and the magnet three 37 generate a large repulsive force, at the same time, the driving piece 2 and the driven piece 3 are pushed away to make them separate from each other, at this time, the water outlet one 12 and the water outlet two 13 are exposed and can be used for pouring water; after the pouring operation is completed, the driving piece 2 is rotated again to reset, so that the magnet one 24 and the magnet two 36 correspond again, at this time, a large attractive force can make the driving piece 2 and the driven piece 3 approach each other, and the water outlet one 12 and the water outlet two 13 are blocked.
