Nested Multi-Cyclone Dust Collector for Compact Vacuum Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collectors with multi-cyclone structures face issues such as increased height, reduced airflow, and decreased cleaning performance due to the inefficient arrangement of second cyclone units, leading to frequent dust disposal and user inconvenience during discharge.
Innovation Solution
A dust collector design featuring a first cyclone unit for filtering dust, a second cyclone unit with left and right cyclone portions for separating fine dust, and a fine dust collecting unit, allowing for efficient arrangement and simultaneous discharge of dust and fine dust through a V-shaped configuration and a handle placement that optimizes space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the second cyclone unit is laminated on the first cyclone unit, then the multi-cyclone structure is formed, but the height of the dust collector increases
Solution Approach 1:
The second cyclone unit is disposed inside the first cyclone unit, with the outer peripheral surface of the second cyclone unit positioned within the inner peripheral surface of the first cyclone unit. This nesting arrangement allows multiple cyclone units to be integrated in a compact configuration, achieving the multi-cyclone structure without increasing the overall height of the dust collector.
2Length of stationary object
If the second cyclone unit is disposed inside or outside the first cyclone unit, then the height is reduced, but the number of second cyclone units is significantly decreased
Solution Approach 1:
The second cyclone unit is disposed inside the first cyclone unit, with the outer peripheral surface of the second cyclone unit positioned within the inner peripheral surface of the first cyclone unit. This nesting arrangement allows multiple cyclone units to be integrated in a compact configuration, achieving the multi-cyclone structure without increasing the overall height of the dust collector.
3Length of stationary object
If the second cyclone unit is disposed inside or outside the first cyclone unit, then the height is reduced, but the sucking force is reduced
Solution Approach 1:
The second cyclone unit is disposed inside the first cyclone unit, with the outer peripheral surface of the second cyclone unit positioned within the inner peripheral surface of the first cyclone unit. This nesting arrangement allows multiple cyclone units to be integrated in a compact configuration, achieving the multi-cyclone structure without increasing the overall height of the dust collector.
4Ease of manufacture
If steps are increased to arrange the second cyclone unit, then the arrangement is achieved, but the overall height of the dust collector increases
Solution Approach 1:
The second cyclone unit is disposed inside the first cyclone unit, with the outer peripheral surface of the second cyclone unit positioned within the inner peripheral surface of the first cyclone unit. This nesting arrangement allows multiple cyclone units to be integrated in a compact configuration, achieving the multi-cyclone structure without increasing the overall height of the dust collector.
5Volume of moving object
If the second cyclone unit is arranged with interference between guide passages, then the compact arrangement is achieved, but the efficient arrangement is difficult
Solution Approach 1:
The second cyclone unit is disposed inside the first cyclone unit, with the outer peripheral surface of the second cyclone unit positioned within the inner peripheral surface of the first cyclone unit. This nesting arrangement allows multiple cyclone units to be integrated in a compact configuration, achieving the multi-cyclone structure without increasing the overall height of the dust collector.
