The invention provides a water control integrated machine with a spilt cavity waterproof function, and belongs to the technical field of water control equipment. According to the water control integrated machine, the problems that an existing water control device shell adopts an external waterproof sealing mode, the sealing effect is poor, the sealed waterproof structure is inconvenient during production debugging, and sealed waterproof performance is prone to being lowered are solved. The water control integrated machine comprises an upper shell, a lower shell, a flow valve sealing shell, a display card-swiping sealing shell and a circuit board sealing shell; and a mounting cavity is formed in the upper shell and the lower shell, and the flow valve sealing shell, the display card-swipingsealing shell and the circuit board sealing shell are mounted in the mounting cavity formed by the upper shell and the lower shell. Through the spilt cavity waterproof function, the water control integrated machine is novel in structure, convenient to mount, obvious in sealing effect and reliable in performance.
