Conventional juicers fail to adequately chop fruits and vegetables, resulting in juice with solid particles, leading to poor taste and frequent blockages, making the user experience cumbersome and labor-intensive.
Innovation Solution
A juicer with an autonomous circulation filtration function, featuring a container, rotating cutter, filter barrel, and return pipe, which refluxes juice for filtering, along with a pressing rod and juice guiding bridge, effectively reducing solid particles and preventing valve blockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional juicer uses simple chopping mechanism, then device complexity is low, but manufacturing precision of juice quality is poor due to insufficient grinding
Solution Approach 1:
The chopping mechanism is divided into multiple cutting layers with different blade configurations. The first cutting layer has blades for initial chopping, while the second cutting layer has blades for further grinding, achieving progressive size reduction of fruit particles to improve juice quality without requiring excessive complexity in a single mechanism
Solution Approach 2:
The fruit is first chopped by the first cutting layer before being subjected to the second cutting layer for further grinding. This preliminary action prepares the material in a state that facilitates more effective subsequent processing, ensuring thorough particle size reduction before juice extraction
2Reliability
If conventional juicer extracts juice without circulation filtration, then productivity is high, but reliability is poor due to valve blockages from solid particles
Solution Approach 1:
The system implements a circulation filtration mechanism where juice is extracted and then fed back through a filter barrel that removes solid particles. The filtered juice is returned to the container while the filter barrel accumulates pulp. This feedback loop continuously monitors and removes particles that would cause blockages, ensuring reliable operation without significantly reducing productivity
Solution Approach 2:
The filter barrel acts as an intermediary component between the juice extraction chamber and the discharge valve. It intercepts solid particles from the extracted juice before they can reach and block the valve, allowing the main extraction process to continue at high productivity while the intermediary handles the filtration function
3Ease of operation
If conventional juicer requires manual filtration, then device complexity is low, but ease of operation is poor due to cumbersome and labor-intensive operations
Solution Approach 1:
The system automatically performs filtration through the circulation mechanism. The pump draws juice through the filter barrel, and the filtered juice is automatically returned to the container while pulp accumulates in the filter barrel. The system also automatically controls the pressing rod to press pulp against the filter mesh, eliminating the need for manual filtration operations
Solution Approach 2:
The pressing rod is designed to move automatically between extended and retracted positions based on the operation phase. During filtration, the pressing rod extends to press pulp against the filter mesh to enhance filtration efficiency. During juice extraction, the pressing rod retracts to avoid interfering with the extraction process, providing dynamic adaptation without requiring manual intervention

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.
