Nested Multi-Cyclone Layout for Compact Dust Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-cyclone dust separating apparatuses for vacuum cleaners are bulky due to their increased volume and complex air passages, making them inconvenient for maintenance and repair, and they lack a filter, which can lead to re-scattering of dust.
Innovation Solution
A compact multi-cyclone dust separating apparatus with a first cyclone chamber, a second cyclone chamber disposed inside the first, and a third cyclone chamber around the periphery, along with a re-scattering prevention cover, which includes multiple holes to prevent dust re-scattering, allowing for efficient dust separation in multiple stages without increasing the cleaner's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a multi-cyclone dust separating apparatus includes multiple cyclone chambers to increase dust separation efficiency, then dust separation efficiency is improved, but the volume and size of the apparatus increases
Solution Approach 1:
The patent applies nesting by placing the second cyclone chamber inside the first cyclone chamber, and positioning third cyclone chambers within the space defined by the first chamber. This nested arrangement allows multiple cyclone chambers to occupy overlapping spatial volumes, thereby increasing dust separation efficiency without proportionally increasing the overall apparatus volume.
2Productivity
If a multi-cyclone dust separating apparatus includes multiple cyclone chambers, then dust separation efficiency is improved, but the air passage becomes complex
Solution Approach 1:
The patent merges the air passage functions by having the first cyclone chamber serve as both a separation chamber and as the housing structure that contains the second cyclone chamber. The outer wall of the first chamber acts as the housing for the nested second chamber, eliminating the need for separate housing structures and simplifying the overall air passage configuration while maintaining multi-stage separation efficiency.
3Ease of repair
If a cyclone dust separating apparatus does not use a filter, then maintenance convenience is improved, but dust re-scattering occurs
Solution Approach 1:
The patent applies preliminary anti-action by introducing a re-scattering prevention cover that actively prevents dust from being re-scattered back into the air passage before the dust can cause harm. This cover is positioned to block the path of rising air currents that would otherwise carry separated dust particles back into the cyclone chambers, thereby preventing re-scattering without requiring filter replacement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The compact design enhances dust separation efficiency while preventing dust re-scattering, maintaining cleaner convenience and reducing maintenance complexity, allowing for a more compact cleaner with improved performance.
Implementation Method 1
a cyclone dust separating apparatus causes drawn-in air to whirl therein and separates dirt from the drawn-in air using a centrifugal force

AI summary
A compact multi-cyclone dust separating is disclosed. The multi-cyclone dust separating apparatus includes a first cyclone chamber that separates dust-laden air drawn from outside, a second cyclone chamber that is disposed in the first cyclone chamber, and that separates dust-laden air drawn from the first cyclone chamber, and a third cyclone chamber that is disposed around a periphery of the first cyclone chamber, and that separates dust-laden air drawn from the second cyclone chamber.
