Abstract: The present disclosure discloses a blade seat assembly including a blade assembly, a clasp assembly, and a blade seat. The blade assembly includes a blade and a shaft, the blade being connected to one end of the shaft. The blade seat defines a mounting groove, and the other end of the shaft detachably is connected to the mounting groove via the clasp assembly. The present disclosure also provides a blending cup assembly and a food processor, which use the blade seat assembly. The technical scheme of the present disclosure aims to enable the blade assembly to be disassembled.

Abstract: The present disclosure provides a food processor which includes a main engine, a stirring cup, and a cup cover assembly. A main control board is defined in the main engine and the stirring cup is mounted on the main engine. The cup cover assembly covers the stirring cup and the bottom of the stirring cup defines a heating device which electrically is connected to the main control board.
