Cyclone Vacuum Inlet Structure for Stable Vortex Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction cleaners with cyclone separators face inefficiencies in dust and debris separation, particularly due to vortex instability and limited dirt collection capacity, leading to reintrainment of separated particles and reduced cleaning effectiveness.
Innovation Solution
The design incorporates a cyclone module assembly with opposed inlets and a vortex stabilizer to maintain a cyclonic airflow vortex, enhancing separation efficiency by stabilizing the vortex tail and improving debris collection, while allowing for modular configurations to optimize airflow and debris discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cyclone separators are used with single inlets, then the structure is simple, but the separation efficiency is limited and vortex stability is poor
Solution Approach 1:
The cyclone separator inlet is divided into multiple opposed inlets instead of a single inlet. This segmentation allows for more uniform airflow distribution and enhanced vortex formation, directly improving separation efficiency while adding manageable structural complexity
Solution Approach 2:
Different regions of the cyclone separator are optimized with specific features: opposed inlets at the upper portion for vortex generation, vortex stabilizer at the lower portion for maintaining vortex integrity, and strategically positioned outlets. This local optimization enhances overall separation performance
2Quantity of substance
If the dirt cup capacity is increased, then more debris can be collected, but the device becomes heavier and larger
Solution Approach 1:
The cyclone separator is positioned within or adjacent to the dirt cup structure, with the vortex stabilizer nested within the cyclone separator. This nesting arrangement maximizes the use of available space, allowing for increased dirt collection capacity without proportionally increasing the overall device volume and weight
3Reliability
If the vortex tail is not stabilized, then the structure is simpler, but separated particles are reintrained and cleaning effectiveness is reduced
Solution Approach 1:
A vortex stabilizer is introduced as an intermediary component within the cyclone separator to maintain vortex integrity and prevent particle reintrainment. This relatively simple structural addition significantly improves cleaning effectiveness by ensuring stable separation without requiring complex control systems

AI summary
A vacuum cleaner has a cyclone module assembly comprising a cyclone separation chamber for separating dust and debris from air with the generation of a cyclonic airflow vortex forming a vortex tail, the cyclone separation chamber having an inlet opening in fluid communication with the suction nozzle through the working air path and an outlet opening for discharging cleaned air, and a dirt cup for collecting dust and debris that is separated from the air in the cyclone separation chamber. The inlet opening in the cyclone separation chamber is formed with a pair of opposed inlets. The opposed inlets can be symmetrically or asymmetrically positioned with respect to each other. The cyclone separation chamber can comprise first and second concentric cyclone separation chambers and the opposed inlets can form the inlet opening to the second or inner cyclone separation chamber. The cyclone separation chamber can further have at least one vortex stabilizer for retaining the vortex tail at a predetermined location with respect to the cyclone separation chamber.
