The utility model relates to a continuously-feeding pressing head mechanism for a household rubbish water extractor. The continuously-feeding pressing head mechanism is characterized by comprising a machine body (1), an oil cylinder base (2), a feeding oil cylinder (3), a baffle (4), a feeding pressing head (5), a lower blade (6), a hopper (7) and an upper blade (8). When the feeding pressing head (5) carries out the circulating movement of advancing and returning through the feeding oil cylinder (3), the circulating and continuous feeding mode that household rubbish is fed, cut and accumulated and drops into a feeding area is achieved at the same time in the feeding part. The continuously-feeding pressing head mechanism has the advantages that continuous feeding is achieved and production efficiency is improved.
