Washing machine anti-overflow assembly and pulsator washing machine

The invention relates to a washing machine anti-overflow assembly and a pulsator washing machine, belongs to the technical field of washing machines, and solves the technical problem that an existing washing machine cannot radically avoid water overflow. The anti-overflow assembly comprises a sensing module which is installed on a washing barrel of the washing machine and used for sensing the water pressure in the washing barrel; the cut-off module is connected with a water inlet system of the washing machine and used for controlling on-off of the water inlet system; the control unit is electrically connected with the induction module and the cut-off module; in the first state, the water pressure in the washing barrel is lower than a threshold value, and the control unit controls the closure module to act to conduct the water inlet system; in the second state, the water pressure in the washing barrel reaches a threshold value, and the control unit controls the closure module to act to disconnect the water inl
