Vacuum Cleaner Sachet Diffuser Structure for Dust Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner filter bags suffer from inadequate dust distribution, leading to premature clogging and reduced service life due to the small dimensioning of deflection devices, which causes dust to accumulate between the inflow opening and the deflection device.
Innovation Solution
A flat vacuum cleaner bag with a diffuser made of material strips or flat structures featuring elongated flow openings, arranged between the bag top and bottom, connected to the bag wall, which swirls incoming air laden with dust particles, preventing clogging and extending the service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a small deflection device is used to deflect incoming air flow, then the device complexity is reduced, but the bag becomes clogged by dust accumulated between the inlet opening and the deflection device, reducing service life
Solution Approach 1:
The diffuser is divided into multiple individual material strips arranged in a specific pattern, allowing dust particles to be distributed across multiple pathways rather than accumulating in a single area. This segmented structure maintains simplicity while preventing clogging by distributing the dust load.
Solution Approach 2:
The diffuser extends into the bag interior along the longitudinal direction, creating a multi-dimensional flow distribution system. This longitudinal extension allows air flow to be distributed throughout the length of the bag, preventing dust accumulation at any single location and significantly extending service life.
2Quantity of substance
If the diffuser area is increased to improve dust distribution, then dust storage capacity is enhanced, but the device complexity increases
Solution Approach 1:
The diffuser strips are strategically positioned in specific regions where dust accumulation is most problematic, rather than uniformly distributing material throughout the bag. This localized approach enhances dust storage capacity in critical areas while minimizing overall device complexity.
Solution Approach 2:
The diffuser is constructed from material strips with flow openings that allow air and dust particles to pass through while maintaining structural integrity. This porous structure enables effective dust distribution and storage without requiring solid, complex barriers.
