• the sealing assembly is disposed above the water dividing member and separately disposed along a circumference direction of the water dividing member,
• the sealing assembly comprises one or more sealing units corresponding to the one or more water dividing holes one to one,
• the one or more sealing units comprise one or more sealing surfaces,
• the drive element is disposed with a transmission surface configured to be interlocked to the one or more sealing units,
• a side of the fixed base facing the water dividing member is disposed with one or more accommodating cavities,
• the number of the one or more accommodating cavities corresponds to the number of the one or more sealing units,
• the one or more sealing units are disposed with through holes enabling the one or more accommodating cavities to be in communication with external sides of the one or more accommodating cavities,
• side walls of the one or more sealing units are disposed with one or more matching surfaces configured to abut the transmission surface, and
• when the drive element moves:
• the transmission surface moves to be interlocked to and engaged with one of the one or more sealing units,
• a corresponding one of the one or more matching surfaces moves along the transmission surface to enable the one of the one or more sealing surfaces to be separated from a corresponding one of the one or more water dividing holes,
• the corresponding one of the one or more water dividing holes is opened, and
• water flows into the one or more accommodating cavities through the one or more through holes.
