Spiral Stirring Paddle Structure for Ice Outlet Residue Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cold beverage makers suffer from insufficient stirring range and agglomeration of materials due to limited spiral stirring paddles, leading to residual materials at discharge ports that hinder efficient discharge and reuse.
Innovation Solution
A spiral stirring paddle with a pair of blades surrounding a central shaft, featuring an L-shaped reflow groove and a reflow side plate, which rotates to convey and separate materials effectively, ensuring thorough stirring and preventing accumulation at discharge ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single spiral stirring paddle is used, then the structure is simple, but the stirring range is limited and material agglomeration occurs
Solution Approach 1:
The single spiral stirring paddle is divided into multiple stirring blades (first stirring blade, second stirring blade, third stirring blade, fourth stirring blade) arranged at different positions and angles. This segmentation allows each blade to cover different areas of the storage container, thereby expanding the overall stirring range and preventing material agglomeration while maintaining structural simplicity through modular design.
2Productivity
If the spiral stirring paddle conveys material once, then discharge speed is fast, but residual material remains at discharge port
Solution Approach 1:
The stirring blades are designed with specific geometries (inclination angles, extended ends) that perform preliminary scraping and pushing actions on the material before it reaches the discharge port. The extended ends of the stirring blades actively scrape residual material from the discharge port area during the conveying process, preventing accumulation before discharge completes.
3Use of energy by moving object
If material is not stirred sufficiently, then energy consumption is low, but material agglomeration affects mouthfeel
Solution Approach 1:
The stirring blades are designed with curved surfaces and optimized inclination angles that create efficient material engagement. The curved geometry of the blades allows them to effectively push and redistribute material with minimal energy input, ensuring thorough mixing and uniform distribution throughout the storage container without requiring excessive rotational force or energy consumption.

AI summary
The present disclosure provides a stirring mechanism and a cold beverage maker. The stirring mechanism includes an ice storage container and a spiral stirring paddle, where the ice storage container is provided with an ice outlet; a pair of stirring blades are connected to a central stirring shaft, and surround the central stirring shaft spirally and alternately along a length direction of the central stirring shaft; a tail end of the stirring blade is close to the ice outlet; and with an outer contour close to an inner wall of the ice storage container, the stirring blade is configured to convey material to the ice outlet during rotation. The spiral stirring paddle can solve the problem of easy agglomeration of the material in the local area due to the insufficient stirring and the small stirring range of the existing ice maker.
