A kind of limited and reliable juicer

Abstract

The invention provides a juice extractor with reliable spacing. The juice extractor comprises a machine base, a juice collection container connected with the machine base, an extruding screw rod longitudinally disposed in the juice collection container and an upper lid covering the upper end of the juice collection container. The upper lid is provided with an opening and a feeding channel communicated with the opening; the extruding screw rod has a body and a screw rod shaft; a helix is arranged on the body; the opening covers a rotation center of the extruding screw rod; the upper end of the extruding screw rod is provided with a positioning structure circumferentially arranged; a spacing structure is circumferentially arranged around the opening of the upper cover; the spacing structure is matched with the positioning structure to space the extruding screw rod; a proportion of an equivalent diameter and a swing diameter of the positioning structure is a; and a is no less than 1 / 3 and no more than 4 / 3. The extruding screw rod applies the circumferential spacing structure, and a matching part between the upper lid and the extruding screw rod can be more balanced and transmission can be more stable; and a problem of crack of the upper lid due to stress concentration can be avoided.

Description

technical field [0001] The invention relates 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.
