Description

Technical Field

[0001] The utility model relates to the technical field of juice extractors, and particularly relates to a juice extraction screw of a juice extractor. Background Art

[0002] The existing juice extractor, such as a juice extraction assembly of a super-large-diameter juice extractor disclosed in Chinese Patent Publication No. CN220800741U on August 28, 2024, includes a fruit cutting cup, a fruit cutting knife, a juice extraction cup, a juice extraction screw, and a juice extraction mesh cylinder. The top of the fruit cutting cup is open, the fruit cutting knife is arranged in the fruit cutting cup, the bottom of the juice extraction cup is screwed and connected to the bottom of the fruit cutting cup, a blanking port is arranged at the bottom of the fruit cutting cup, the blanking port communicates the juice extraction mesh cylinder with the juice extraction cup, the juice extraction screw is arranged in the juice extraction mesh cylinder, the top of the juice extraction screw drives the fruit cutting knife to rotate, and the bottom of the juice extraction cup is fixedly connected to the machine base of the juice extractor. The juice extraction assembly of the super-large-diameter juice extractor of the utility model can automatically cut the pulp into small pieces in advance. The pulp in the fruit cutting cup falls into the juice extraction cup from the blanking port, and then is juiced by the juice extraction screw. However, when the juice extraction screw of the above juice extractor is juicing, the juice yield is low and the juicing is not sufficient. Therefore, the juice extraction screw of the existing juice extractor needs to be further improved. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a juice extraction screw of a juice extractor with a high juice yield.

[0004] The purpose of the utility model is achieved as follows:

[0005] A juice extraction screw of a juice extractor includes a screw body. A plurality of spiral and parallel extrusion ribs are arranged on the outer wall of the screw body. The plurality of extrusion ribs are spirally wound around the outer wall of the screw body from top to bottom. At least the upper end of one extrusion rib spirally winds upwards to the top of the screw body to form a fruit cutting blade. A fruit cutting notch is arranged on the fruit cutting blade. The extrusion rib is formed by sequentially arranging a plurality of extrusion strips at intervals. The interval between two adjacent extrusion strips forms a pulp passing opening. During the rotation and juicing process of the juice extraction screw of the utility model, due to the resistance of the rotation and juicing, the pulp will enter the upper extrusion rib through the pulp passing opening upwards, and the pulp is screwed and extruded again by the upper extrusion rib. The pulp is repeatedly extruded and juiced, thereby improving the juice yield.

[0006] The utility model can also be further improved as follows.

[0007] An upper transmission structure is arranged at the top of the screw body, and a lower transmission structure is arranged at the bottom of the screw body.

[0008] The screw body is thick at the bottom and narrow at the top.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. During the rotation and juicing process of the juice extraction screw of the present utility model, due to the resistance of the rotation and juicing, the pulp will enter the upper extrusion rib through the opening, and the pulp is screwed and extruded again by the upper extrusion rib. The pulp is repeatedly extruded for juicing, thereby increasing the juice yield.

[0011] 2. Additionally, when the volume of the pulp is large, the fruit cutting notch can cut the pulp into smaller pieces, which are more convenient for juicing, resulting in higher juicing efficiency and juice yield. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0018] Embodiment 1, as Figures 1 to 4 shown, a juice extraction screw of a juice extractor includes a screw body 1. A plurality of spiral and parallel extrusion ribs 11 are provided on the outer wall of the screw body 1. The plurality of extrusion ribs 11 are wound around the outer wall of the screw body 1 from top to bottom. The upper ends of two of the extrusion ribs 11 are spirally wound upwards to the top of the screw body 1 to form a fruit cutting blade 14. A fruit cutting notch 15 is provided on the fruit cutting blade. The extrusion rib 11 is formed by sequentially arranging a plurality of extrusion strips 12 at intervals. The interval between two adjacent extrusion strips 12 constitutes a pulp passage opening 13. When the volume of the pulp is large, the fruit cutting notch 15 can cut the pulp into smaller pieces, which are more convenient for juicing and result in higher juicing efficiency. During the rotation and juicing process of the juice extraction screw of the present utility model, due to the resistance of the rotation and juicing, the pulp on the next extrusion rib 11 will enter the upper extrusion rib 11 through the pulp passage opening, and the pulp is screwed and extruded again by the upper extrusion rib 11. The pulp is repeatedly extruded for juicing, thereby increasing the juice yield.
