A Juicer with Reliable Structure

Abstract

The invention provides a juicer with a reliable structure. The juicer comprises a machine base, a juice collection container connected to the machine base, an extrusion screw rod longitudinally disposed in the juice collection container, and an upper cover which covers an upper port of the juice collection container, wherein an opening and a feeding channel communicating with the opening are formed in the upper cover; a rotary feeding device is disposed on the upper end of the extrusion screw rod; the rotary feeding device and the extrusion screw rod form an integral manner; the extrusion screw rod drives the rotary feeding device to move; the rotary feeding device comprises a feeding hole and a discharge hole; the feeding hole and the opening are disposed correspondingly; a circumferential limiting structure is disposed on the upper cover; a positioning structure is disposed circumferentially on the rotary feeding device; and the circumferential limiting structure is coordinated withthe positioning structure to conduct circumferential limiting of the extrusion screw rod. Through coordination of the limiting structure and the positioning structure, assembly accuracy of the rotaryfeeding device, the extrusion screw rod and the juice collection container can be further increased; and reliability of transmission can be ensured.

Description

technical field [0001] The invention belongs to the field of food processors, in particular to a juice extractor. Background technique [0002] Existing screw squeeze juicers generally include a machine base, a juice collection chamber connected to the machine base, a screw and an extrusion filter cartridge arranged in the juice collection chamber, and a loamer covering the top of the juice collection chamber. The cover is provided with a feeding channel connected with the juice collecting chamber, and the material moves downwards driven by the screw after passing through the feeding channel, and is squeezed and squeezed in the crushing gap formed between the juice collecting chamber and the extrusion filter cylinder. Since the screw rotates around the screw shaft, the linear velocity at the center of the screw shaft is zero, so the feed channel usually needs to be offset so that the material entering from the feed channel avoids the central area of ​​the screw, and the feed...

AI Technical Summary

Problems solved by technology

In this scheme, since the pressing treatment part protrudes from the upper end surface of the upper cover, the upper cover takes up a lot of space, and the shape is not reasonable or beautiful enough. In addition, the upper end of the screw pressing treatment part is provided with a shaft hole for limiting the upper end of the screw shaft. The central positioning method needs to meet the requirements of large-diameter feeding, and the extrusion force on the screw becomes larger, and the corresponding force on the upper cover increases, causing the upper cover to be easily cracked due to stress concentration, which affects the service life, and makes the entire upper cover structure complicated and difficult. Cleaning, the material needs to turn when passing through the feeding channel to enter the extrusion screw for juicing. The material passes through a long path and is easy to accumulate in the pressing treatment part. Moreover, the automatic feeding effect of this juicer structure material is not ideal, which affects the user experience.
