Juicer Circulation Filtration System to Reduce Outlet Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juicers fail to adequately chop fruits and vegetables, resulting in juice with high solid content, clogged outlets, and cumbersome operation, leading to a poor user experience and increased maintenance costs.
Innovation Solution
A juicer with an autonomous circulation filtration function, featuring a container, rotating cutter, filter barrel, and return pipe that refluxes juice for filtering, along with a pressing rod and juice guiding bridge, effectively reduces solid particles and prevents outlet blocking, enhancing the juicing process and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional juicer uses simple chopping mechanism, then device complexity is low, but manufacturing precision of juice quality deteriorates
Solution Approach 1:
The juicer is divided into distinct functional modules: a chopping assembly with cutter head for initial fruit breakdown, and a separate grinding assembly with grinding roller for fine particle reduction. This segmentation allows each module to specialize in a specific task, achieving high juice quality without requiring the entire device to be overly complex.
Solution Approach 2:
The chopping assembly performs preliminary chopping of fruits before the grinding assembly processes them further. This preliminary action breaks down large fruit pieces into smaller fragments, making the subsequent grinding operation more effective and enabling fine particle reduction without excessive complexity.
2Device complexity
If conventional juicer lacks filtration function, then device complexity is low, but harmful factors increase due to outlet blocking
Solution Approach 1:
The filter barrel is positioned to receive juice and fruit particles during the grinding process, performing preliminary filtration before juice exits the device. This preliminary filtration action prevents solid particles from accumulating and blocking the outlet, eliminating the harmful effect without requiring a separate complex filtration system.
Solution Approach 2:
The filtration function is merged with the existing grinding and juice discharge pathway. The filter barrel integrates into the juice flow path, combining filtration with the primary juicing operation, thereby preventing outlet blocking without adding significant device complexity.
3Device complexity
If conventional juicer requires manual operation, then device complexity is low, but ease of operation deteriorates
Solution Approach 1:
The control assembly enables automatic control of the juicer operation. Users can set parameters such as grinding time and speed, and the system automatically executes the juicing process without requiring manual intervention during operation. This self-service capability significantly improves ease of operation while maintaining reasonable device complexity through automated control.
4Device complexity
If conventional juicer lacks circulation function, then device complexity is low, but productivity deteriorates due to incomplete grinding
Solution Approach 1:
The circulation assembly creates a feedback loop where juice and unground particles are returned from the filter barrel to the grinding assembly for further processing. This feedback mechanism ensures that particles are ground to the desired fineness before juice extraction, improving juicing efficiency and productivity without requiring excessive device complexity.
Solution Approach 2:
The circulation system maintains continuous grinding action by repeatedly passing juice and particles through the grinding assembly until adequate fineness is achieved. This continuous useful action ensures complete grinding and maximizes juice extraction efficiency, improving productivity while keeping the circulation system relatively simple.

AI summary
The present disclosure provides a juicer having an autonomous circulation filtration function and a working method thereof. The juicer includes a container, a rotating cutter arranged on a bottom portion of the container, a filter barrel, and a return pipe. The return pipe is configured to reflux juice in the container into the filter barrel for filtering. A lower end of the filter barrel is arranged in the container. An upper end and a lower end of the return pipe respectively form a juice outlet end and a juice inlet end. The juice is introduced into the filter barrel through the juice outlet end and the juice inlet end. A press-in portion configured to press the juice into the juice inlet end is eccentrically arranged on the rotating cutter. A liquid inlet corresponding to the juice outlet end of the return pipe is defined on the filter barrel.
