Solution Overview
Problem
Conventional home juicers face issues with high failure rates due to gear breakage or abrasion, complex assembly requirements, and difficulty in maintaining cleanliness, especially in removing residue from gear gaps, which complicates juice extraction and quality.
Innovation Solution
A juicer design that eliminates the complicated geared rotating power transmission structure by directly combining the feed screw with the rotary brush, allowing for simple assembly and easy cleaning, while using a feed screw with spiral blades and a residue drop hole for efficient residue discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a geared rotating power transmission structure is used to rotate the rotary brush, then the rotary brush can be rotated to brush the strainer, but the device complexity increases and the failure rate increases due to gear breakage or abrasion
Solution Approach 1:
The patent removes the intermediate gear from the power transmission system, extracting the problematic component that caused complexity and reliability issues. The feed screw directly transmits power to the rotary brush through a simplified connection, eliminating the need for multiple engaged gears while maintaining the brushing function.
Solution Approach 2:
The patent combines the power transmission function and the brushing function into a more integrated system. The feed screw directly drives the rotary brush without intermediate gears, merging the rotational motion transmission with the brushing action in a simpler configuration that reduces failure points.
2Ease of operation
If multiple gears are engaged to rotate the rotary brush, then the rotary brush can be driven, but the assembly difficulty increases due to precise engagement requirements
Solution Approach 1:
The patent extracts the intermediate gear from the system, eliminating the complex multi-gear engagement assembly process. The simplified direct connection between the feed screw and rotary brush requires minimal precision alignment, making assembly much easier for users.
3Ease of operation
If gears are installed in the juicer housing, then power transmission is achieved, but the cleanliness maintenance becomes difficult due to residue accumulation in gear gaps
Solution Approach 1:
The patent removes all gears from the housing interior, eliminating the gaps and crevices where residue accumulates. The simplified direct-drive structure has smooth surfaces that are easily accessible for cleaning, allowing users to maintain hygiene without disassembling complex gear mechanisms.
Solution Approach 2:
The patent segments the cleaning function from the power transmission function, allowing the housing interior to be completely accessible for cleaning while the feed screw and rotary brush remain as separate, easily removable components for maintenance.
4Productivity
If a complicated gear mechanism is used, then the rotary brush can be rotated, but the productivity decreases due to frequent disassembly and cleaning requirements
Solution Approach 1:
The patent extracts the time-consuming gear cleaning requirement from the maintenance routine. The simplified structure eliminates gaps and hidden surfaces, allowing rapid cleaning or complete disassembly for thorough washing, thereby reducing downtime and increasing overall productivity.

Function Achieved in This Case
This design reduces the failure rate, simplifies assembly and cleaning, ensures the juicer remains in a clean and hygienic state, and effectively prevents residue from contaminating juice, improving juice quality and user convenience.
Implementation Method 1
a feed screw (200) having a drive shaft hole (230) in a lower part thereof so as to receive the drive shaft of the main body through the drive shaft hole, the feed screw being rotatably installed on the main body at a location inside the strainer, with spiral blades formed on an outer surface of the feed screw
Implementation Method 2
a rotary brush (400) placed between an inner surface of the housing and an outer surface of the strainer, the rotary brush being open in upper and lower ends thereof and having a strainer brush (410) configured to brush the outer surface of the strainer

AI summary
The present invention relates to a juicer in which: a driving shaft hole having a driving shaft inserted therein is formed on the lower part of a rotary brush, which is mounted between an inner wall of a housing and an outer wall of a net drum and has opened upper and lower surfaces and has a net brush for brushing the outer wall of the net drum, so that the driving shaft hole is rotationally mounted on a body; and a screw is arranged inside the net drum and has a screw spiral formed on the outer surface thereof, wherein a screw coupling protrusion or a screw coupling groove is formed on the upper part of the screw and a rotary brush coupling groove or a rotary brush coupling protrusion is formed on the upper part of the rotary brush such that the screw coupling protrusion and the rotary brush coupling groove are coupled or the screw coupling groove and the rotary brush coupling protrusion are coupled in such a manner that the rotary brush is directly rotated by the screw during the rotation of the screw, thereby reducing a failure rate caused by damage to or wearing down of components such as gears and the like and providing a simple and easy assembling operation.
