A fruit and vegetable juicing device having a feed tube, a juice collector and a grating disc carrying a frusto-conical sieve, the grating disc having a first array of grating teeth, a secondary processing surface with a second array of grating teeth; each tooth having one leading edge and one trailing edge, wherein the juice collector has either an internal helical ramp with an elevated discharge nozzle or a circumferential trough having a lowest point that leads to a discharge nozzle.

Embodiment provides a food processor, comprising: a base assembly; a food processing cup mounted on the base assembly, and including a cup body and a working screw rotatably mounted in the cup body, the cup body can be used to store food juice, and a first slag outlet is provided on the cup body; a feeding assembly is sealed and mounted on the cup mouth end of the cup body; a slag receiving device is hermetically connected to the first slag outlet for collecting food waste; a sealed cavity formed between the cup body, the feeding assembly, and the slag receiving device to conduct them to each other; and an extraction assembly can communicate with the sealed cavity and is used for extracting air in the sealed cavity.

A screw for a juicer according to an exemplary embodiment of the present invention with a plurality of screw threads formed on the outer circumferential surface includes a cut-out portion for accommodating the input juice material and primarily compressing the juice material with the plurality of screw threads, and a compression portion for further compressing and crushing the juice material transferred from the cut-out portion, and a rough area having a rough surface is formed in the compression portion.

The present disclosure provides a juicer having an autonomous circulation filtration function and a working method thereof. The juicer includes a container, a rotating cutter arranged on a bottom portion of the container, a filter barrel, and a return pipe. The return pipe is configured to reflux juice in the container into the filter barrel for filtering. A lower end of the filter barrel is arranged in the container. An upper end and a lower end of the return pipe respectively form a juice outlet end and a juice inlet end. The juice is introduced into the filter barrel through the juice outlet end and the juice inlet end. A press-in portion configured to press the juice into the juice inlet end is eccentrically arranged on the rotating cutter. A liquid inlet corresponding to the juice outlet end of the return pipe is defined on the filter barrel.

The invention provides a squeezing device, which comprises a squeezing structure and a squeezing head; the internal of the squeezing device is provided with a holding cavity, a squeezing cavity and a diversion cavity, the diversion cavity has a relatively arranged connection port I and a connection port II, the connection port I is connected to the holding cavity, and the connection port II is connected to the squeezing cavity; the cross section area of the connection port I is greater than that of the connection port II; the squeezing head is at least partially placed in the squeezing cavity, and the squeezing head is arranged with respect to the squeezing structure for relative rotation. The main body is used to drive the squeezing head of the squeezing device for rotation.

Embodiments provide a screw, a food processing cup assembly, and a food processor. The screw includes a screw body including a feeding area for feeding and a crushing area connected to the feeding area; a first spiral rib is spirally arranged on the feeding area along the axial direction of the screw body, and extending to the crushing area along a top of the screw body; a cutting surface extending from the top of the screw body to the crushing area; second spiral ribs are disposed on the screw body at intervals along the axial direction of the screw body.

Provided are an uncovering assembly of a household appliance, and a household appliance. A positioning portion cooperates with a positioning structure on a shell of the household appliance in the uncovering assembly, a cover is prevented from being loosened relative to the shell, in this way visual fool proofing may be achieved. A lock catch switches from an unfastening position to a fastening position after the positioning portion cooperates with the positioning structure. The lock catch, after entering the fastening position, is in mutual restriction with a fastening structure in a vertical direction.
