Solution Overview
Problem
Cyclonic dedusting devices in vacuum cleaners, especially those for large air flow, are bulky, increasing manufacturing costs and user inconvenience while traditional filter devices lead to motor burnout and performance issues due to clogged filter holes.
Innovation Solution
A subsection dedusting device incorporating an upper cyclone separator with multiple lower cyclone separators, where the wind outlet of the upper cyclone is communicated with the wind inlets of the lower cyclone separators, optimizing airflow without increasing the device's bulk and maintaining high dedusting efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cyclonic dedusting device is used to achieve fine dedusting effect, then dedusting efficiency is improved, but device bulk increases
Solution Approach 1:
The cyclonic dedusting device is divided into multiple independent cyclone separators (typically 3-5 smaller cyclones) arranged in parallel, each handling a portion of the airflow. This segmentation allows the system to achieve the required total dust separation capacity with a more compact overall volume compared to a single large cyclone, while maintaining high dedusting efficiency through multiple simultaneous separation zones.
2Quantity of substance
If a large bulk cyclonic dedusting device is used for large air flow vacuum cleaners, then air flow capacity is improved, but manufacturing cost increases
Solution Approach 1:
The system uses multiple standardized cyclone separator modules that can be manufactured independently using similar tooling and processes. This modular approach allows for economies of scale in manufacturing each module, and the total air flow capacity is achieved by parallel arrangement rather than scaling up a single large component, thereby reducing overall manufacturing complexity and cost.
Solution Approach 2:
Multiple cyclone separator modules are combined in parallel within a common housing structure, sharing common inlet and outlet ducts. This merging approach achieves high air flow capacity without requiring a proportionally large housing volume, reducing material costs and simplifying assembly compared to a single large-diameter cyclone system.
3Quantity of substance
If a large bulk cyclonic dedusting device is used for large air flow vacuum cleaners, then air flow capacity is improved, but device bulk increases
Solution Approach 1:
The airflow is divided into multiple parallel streams, each processed by a separate cyclone separator module. This segmentation enables the system to handle large total air flow volumes through multiple smaller channels rather than requiring a single large-volume chamber, achieving high air flow capacity in a compact configuration that fits within standard vacuum cleaner size constraints.
Solution Approach 2:
The multiple cyclone separator modules are arranged in a compact three-dimensional configuration within the housing, utilizing vertical and lateral space efficiently. This spatial arrangement allows high air flow capacity to be achieved without a proportional increase in the device's external dimensions, maintaining a compact form factor despite the increased internal processing capacity.

Function Achieved in This Case
This configuration enhances airflow quantity and maintains high dedusting efficiency while reducing bulk, minimizing pressure loss and preventing secondary pollution, thus extending the vacuum cleaner's performance and lifespan.
Implementation Method 1
dust particles drop into a bottom of a dust collecting barrel along the side wall of the conical barrel due to centrifugal force caused by cyclonic air flow
Implementation Method 2
a wind inlet tube enters into a side wall of an upper portion of the conical barrel along a tangent direction, so that the dust-laden air flow entering the conical barrel through the wind inlet tube produces cyclone
