Cyclone Deflector Collar Structure for Low-Recirculation Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cyclonic separation devices in bagless vacuum cleaners face challenges in reducing waste recirculation while minimizing the risk of trapping hair and bulky items, and existing solutions either compromise efficiency or increase costs.
Innovation Solution
A cyclonic separation device with a deflector featuring a flat base, a cylindrical collar, sinusoidal free edge, axial ribs, and peripheral ribs that create distinct zones for separation and storage, optimizing air flow to retain waste without snagging, and maintaining a distance between the collar and container to facilitate efficient waste transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a grid separator is used to trap waste, then separation efficiency is improved, but the risk of hair snagging and waste trapping increases
Solution Approach 1:
The separator is divided into multiple sections: an upper grid separator for initial waste trapping and a lower toothless rib section for gentle waste guidance. This segmentation allows different zones to perform different functions - the grid catches bulk waste while the toothless lower section prevents hair snagging during the emptying process.
Solution Approach 2:
Different parts of the separator have different structures optimized for their specific functions. The upper portion uses a grid pattern for effective waste interception, while the lower portion uses smooth toothless ribs for gentle waste guidance. This local differentiation resolves the contradiction by applying the right structure in the right location.
2Object-affected harmful factors
If toothless ribs are used to prevent waste rising, then hair snagging is reduced, but small volatile waste may be retained improperly
Solution Approach 1:
The separator is divided into multiple sections: an upper grid separator for initial waste trapping and a lower toothless rib section for gentle waste guidance. This segmentation allows different zones to perform different functions - the grid catches bulk waste while the toothless lower section prevents hair snagging during the emptying process.
Solution Approach 2:
Different parts of the separator have different structures optimized for their specific functions. The upper portion uses a grid pattern for effective waste interception, while the lower portion uses smooth toothless ribs for gentle waste guidance. This local differentiation resolves the contradiction by applying the right structure in the right location.
3Productivity
If the distance between deflector and separator external diameter is reduced to isolate separation and storage zones, then separation efficiency is improved, but passage of bulky waste is limited
Solution Approach 1:
The deflector incorporates a localized wave-shaped structure at its lower edge that creates a gradual, undulating transition zone. This local modification allows bulky waste to pass through smoothly while still maintaining the isolation between separation and storage zones, resolving the contradiction between efficiency and adaptability.
4Productivity
If a cylindrical collar is added to the deflector to enhance zone delimitation, then separation efficiency is improved, but device complexity increases
Solution Approach 1:
The cylindrical collar is integrated directly into the deflector structure, merging two components (deflector and collar) into a single unified piece. This eliminates the need for separate assembly steps and reduces overall device complexity while still achieving the desired zone delimitation effect.
