Nested Cyclone Dust Collector to Reduce Height and Maintain Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collectors face issues with increased height due to multi-stage cyclone separators, reduced suction force, and inefficient dust collection and filtration, leading to scattered debris and reduced cleaning performance.
Innovation Solution
A dust collector design featuring a first container with a first tube-body, a vacuum motor, and flow-guiding units that form a vortex to separate dust into multiple containers, with air passing through a filter for purification, allowing for effective dust collection and air filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multi-stage cyclone separators are vertically arranged to separate dust, then dust separation performance is improved, but the height of the dust collector increases
Solution Approach 1:
The patent places the second cyclone separator inside the first cyclone separator, with the outer casing of the second cyclone separator positioned within the inner space of the first cyclone separator. This nested arrangement allows multi-stage dust separation while maintaining a compact overall height, resolving the contradiction between separation performance and collector height.
2Length of stationary object
If the dust collector is designed with a slim profile to reduce height, then the height is reduced, but the actual space volume for dust collection is reduced
Solution Approach 1:
By nesting the second cyclone separator within the first cyclone separator's inner space, the patent utilizes otherwise wasted vertical space. This allows the dust collector to maintain a slim external profile while providing sufficient internal volume for effective dust collection through multi-stage separation.
Solution Approach 2:
The patent transitions from a single-stage horizontal arrangement to a multi-stage vertical nested arrangement, utilizing the vertical dimension more efficiently. This dimensional reorganization allows compact height while maintaining adequate collection volume through improved space utilization.
3Length of stationary object
If the second cyclone separator is set in the first cyclone separator to reduce height, then the height is reduced, but the number of second cyclone separators is reduced, decreasing suction force
Solution Approach 1:
The nested configuration allows the second cyclone separator to be positioned within the inner space of the first cyclone separator without excessive height increase. This arrangement preserves suction force by maintaining an adequate number of second cyclone separators while achieving compact dimensions.
Solution Approach 2:
The patent divides the dust separation function into multiple stages with the first cyclone separator handling coarse dust and the second cyclone separator handling fine dust. This segmentation allows each stage to be optimized for its specific function while working together to maintain overall suction force and separation efficiency.
4Power
If complex flows including high-speed swirling flow are present, then suction force is generated, but foreign matter and dust cannot be effectively introduced into the storage area and may flow back upstream
Solution Approach 1:
The patent segments the dust collection process into distinct stages: the first cyclone separator collects coarse dust and debris in its inner space, while the second cyclone separator collects fine dust. This segmentation prevents complex flows from causing backflow by providing intermediate collection points that stabilize the flow path.
Solution Approach 2:
The first cyclone separator acts as an intermediary between the suction source and the second cyclone separator. It初步 separates coarse dust, which stabilizes the flow before it enters the second cyclone separator, preventing chaotic flows from causing backflow and improving overall collection reliability.

Function Achieved in This Case
The design enhances dust collection efficiency, reduces the risk of debris scattering, and maintains suction force while providing a compact profile for improved cleaning performance and air purification.
Implementation Method 1
the first tube-body sucks in air, so that the dust and debris in the air enter the first container
Implementation Method 2
the air sequentially passes through the first flow-guiding unit and the second flow-guiding unit to form a vortex to make the fine dust fell into the second container and the third container
Implementation Method 3
the air sequentially passes through the first flow-guiding unit and the second flow-guiding unit to form a vortex
Implementation Method 4
the air is finally discharged by the vacuum motor after passes through the filter
