Inclined Cyclone Dust Collector Layout to Prevent Dust Scattering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners with cyclone dust collecting apparatuses face challenges in maintaining a compact size while effectively separating and collecting dust, as vertically mounted cyclone dust collecting apparatuses increase the cleaner's size and horizontally mounted ones suffer from dust scattering due to turning currents.
Innovation Solution
The cyclone dust collecting apparatus is inclined at an angle of 60° to 85° within the cleaner body, with air currents in the cyclone unit and dust collecting unit formed in opposite directions to prevent dust scattering, utilizing a first guide for linear direction and a second guide for curved direction changes to ensure efficient collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cyclone dust collecting apparatus is vertically mounted to maximize dust separating ability, then the dust separation efficiency is improved, but the cleaner body increases in entire size
Solution Approach 1:
The cyclone dust collecting apparatus is mounted at an inclined angle (45° to 60°) rather than vertically or horizontally, changing the spatial orientation dimension to achieve both compact size and effective dust separation. This angular mounting allows the apparatus to fit within a smaller footprint while maintaining the necessary separation performance.
2Volume of moving object
If the cyclone dust collecting apparatus is horizontally mounted to maintain compact size, then the cleaner body size is reduced, but the dust or dirt scatters or flies upward again due to turning current
Solution Approach 1:
By mounting the cyclone apparatus at an inclined angle rather than horizontally, the apparatus achieves a compromise between compact size and dust collection effectiveness, preventing dust scattering while maintaining a reduced footprint.
Solution Approach 2:
The mounting angle parameter is optimized to a specific range (45° to 60°) to balance the competing requirements of compact size and dust separation efficiency, changing the operational parameters to achieve both goals simultaneously.
3Volume of moving object
If the cyclone dust collecting apparatus is made small to maintain compact size, then the cleaner body size is reduced, but the dust separating function becomes less efficient due to influence from turning current
Solution Approach 1:
The inclined mounting angle creates favorable airflow patterns within the compact cyclone chamber, allowing efficient dust separation even in a reduced-size apparatus by optimizing the spatial configuration of air currents.

This configuration allows for a compact cleaner body size while preventing dust from scattering or flying upward, ensuring efficient dust separation and collection.
Implementation Method 1
a cyclone unit to form a first current turning in a first direction thus to separate the dust or dirt and the air drawn therein from each other
Implementation Method 2
the dust outlet has a side formed adjacent to an inner wall of the dust collecting unit to form a second current turning in a second direction opposite to the first direction thus to allow the dust or dirt discharged through the dust outlet to whirl along the inner wall of the dust collecting unit
