Abstract: The present disclosure discloses an integrated molded structure of an outer tub and a direct drive motor stator of a drum washing machine, including a stator body and an outer tub body that are integrally injection-molded. The stator body and the outer tub body are integrally injection-molded in order to improve the production efficiency of the stator body and the outer tub body and the assembly quality therebetween. The stator body and the outer tub body are integrally injection-molded, without mechanically connecting the stator body and the outer tub body with screws in order to reduce assembly procedures of mechanical connection with the screws, and meanwhile, to reduce the thickness obtained after the stator body and the outer tub body are assembled, thereby reducing the overall thickness of the drum washing machine.

Abstract: A fertilizer mixer includes a housing, a plurality of supporting rods, a roof plate, a mixing room, a lifting mechanism, a stirring mechanism, a control mechanism, a driving mechanism, and a cleaning mechanism. The housing includes a top end and one end of each of the plurality of supporting rods is disposed on the top end. The roof plate is disposed on the other end of each of the plurality of supporting rods. The stirring mechanism is fixed on the roof plate. The mixing room includes a bottom wall and the housing includes an inner bottom surface. The mixing room includes a discharge port disposed on the bottom wall, and a seal plug disposed in the discharge port. The lifting mechanism is disposed between the bottom wall and the inner bottom surface and an outer sidewall of the mixing room abuts against an inner sidewall of the housing.
