Solution Overview
Problem
Existing juice extraction modules suffer from issues such as dregs leaking into the juice, increased weight and volume due to complex driving transmission paths, and inefficient crushing of raw materials with long fibers, leading to degraded juice texture and extraction efficiency.
Innovation Solution
A juice extraction module featuring a juice extraction mesh with a hollow dregs blocking part, a rotating brush, and a simplified driving transmission assembly, which includes a driving gear and driven gear isolated from the juice extraction mesh and rotating brush, along with elastic support parts to prevent dregs leakage and enhance airtightness and crushing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a through hole packing is used to prevent juice from flowing into the driving body, then airtightness is improved, but the friction area with the screw increases which hinders rotation and increases driving load
Solution Approach 1:
The patent extracts the sealing function from the through-hole packing and relocates it to a sealing ring positioned in a groove at the lower end of the screw. This removes the harmful friction effect while preserving the airtightness function, as the sealing ring only contacts the housing bottom surface without interfering with screw rotation.
2Device complexity
If the lower end of the screw passes through the juice extraction mesh to be inserted into the housing, then the structure is simplified, but dregs are leaked to the housing through the gap between the screw and juice extraction mesh
Solution Approach 1:
The patent introduces a sealing ring as an intermediary element between the screw and the housing bottom surface. This sealing ring fills the gap that would otherwise allow dregs to leak, while the screw still passes through the juice extraction mesh and maintains its simplified structural arrangement.
3Manufacturing precision
If lattice-shaped ribs are formed at the bottom of the screw to crush dregs, then dregs crushing is improved, but raw materials with long and tough fibers are not finely cut and are pushed up without being discharged
Solution Approach 1:
The patent applies different structural features to different locations of the screw: the outer peripheral surface has helical grooves for conveying and cutting fibrous materials, while the bottom surface has crushing ribs for dregs. This local differentiation allows the screw to simultaneously handle both fibrous materials and dregs effectively without compromising discharge speed.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively blocks dregs from entering the juice, reduces the module's weight and volume, and improves juice extraction efficiency by finely crushing raw materials, maintaining airtightness and enhancing the texture of the extracted juice.
Implementation Method 1
at least one elastic support part configured to be mounted in the dregs blocking part, have an inner circumferential surface facing an outer circumferential surface of the driving shaft, and be disposed at one side of the driving shaft

AI summary
Disclosed herein is a juice extraction module (100) for juice capable of fundamentally blocking the introduction of dregs which degrade a texture of food when being mixed with the juice. According to the present invention, a dregs blocking part (112, 2310) is provided which isolates between the bottom surface of the juice extraction mesh (110) and the bottom of the container (130) to fundamentally block the introduction of dregs into juice, thereby improving a texture of food.
