When it works, first, the two groups of connecting blocks are respectively threadedly connected to the two groups of fixing frames, then the clamped hidden plate is taken out, and then the hose is connected between the first fixing frame and the second fixing frame through the two groups of connectors. Then, when the rubber plug blocks the clamping hole, the two groups of floor drains can be used separately. When the dry area drain pipe is not used for a long time, the rubber plug is pulled out by driving the connecting rod through the rubber block. Then, the water drained from the wet area floor drain will be discharged into the dry area floor drain through the hose and sealed by the second blocking block to prevent it from smelling upwards. And when the wet area cannot drain quickly, the drainage can also be shared through the hose and the dry area drain pipe, so that the dry area floor drain can prevent the odor of the drain pipe from flowing back through the water seal state between the blocking block and the fixing frame. If the dry area drain pipe also drains frequently, the rubber plug is clamped with the clamping hole by driving the rubber plug through the rubber head and the connecting pipe, so as to disconnect the connection between the two dry and wet drainage areas.
