Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-step cyclone dust separators in vacuum cleaners have imperfect suction efficiency due to inadequate separation of dust particles by size.
Innovation Solution
A multi-cyclone dust separator with at least three serially arranged dust separation units, each designed to separate dust of different sizes, enhancing the separation process and improving suction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a two-step cyclone separator is used, then the structure is simple, but the suction efficiency is imperfect
Solution Approach 1:
The dust separator is divided into multiple independent cyclone chambers (first, second, and third cyclone chambers) that process dust in sequential stages. Each chamber handles a specific size range of dust particles, with the first chamber separating larger particles, the second chamber separating medium particles, and the third chamber separating fine particles. This segmentation allows the system to achieve high suction efficiency across different particle sizes without requiring an overly complex single-chamber design.
Solution Approach 2:
The patent transitions from a single-dimensional (one-chamber) or two-dimensional (two-chamber vertical stacking) design to a three-dimensional multi-chamber configuration. The cyclone chambers are arranged in a specific spatial configuration with interconnected dust outlets and air inlets, creating a three-dimensional flow path that maximizes dust separation efficiency while managing the complexity of the overall structure.
2Manufacturing precision
If multiple dust separation units are added to improve separation precision, then the dust separation precision is improved, but the device complexity increases
Solution Approach 1:
The dust separation function is segmented into three distinct cyclone chambers, each optimized for a specific particle size range. The first cyclone chamber separates particles of a certain size through its specific inlet and outlet configuration, the second chamber handles a different size range with its own optimized geometry, and the third chamber captures the finest particles. This segmentation achieves high dust separation precision across the entire particle size spectrum while keeping each individual chamber's design relatively simple and modular.

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 multi-cyclone dust separator effectively separates dust by size, improving suction and cleaning efficiency in vacuum cleaners by utilizing a layered structure of cyclone units to capture larger, medium, and fine dust particles.
Implementation Method 1
a cyclone dust separator generates a whirling air current in a cyclone chamber and separates dust and dirt from external air using a centrifugal force of the whirling air current

AI summary
A multi-cyclone dust separator according to an embodiment of the present invention comprises at least three dust separation units for separating dust stepwise from relatively larger size. The dust separation units comprise a first dust separation unit primarily separating dust from external air drawn in; a second dust separation unit secondarily separating dust from the air primarily dust-separated by the first dust separation unit; and a third dust separation unit thirdly separating dust from the air secondarily dust-separated by the second dust separation unit. Here, the first to third dust separation units are multi-layered in a serial manner.
