Block-Base Vacuum Cleaner Bag Diffuser for Dust Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner bags suffer from inadequate dust distribution, leading to premature blockage and reduced dust storage capacity and lifespan due to insufficient airflow distribution at the inlet opening.
Innovation Solution
A block-base bag with at least one diffuser made of strips or sheet materials featuring oblong-shaped flow openings, which are connected to the bag wall and designed to create turbulence in the incoming airflow, preventing blockages and enhancing dust storage capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a small deflection device is fitted at the inlet opening to deflect airflow, then the device complexity is reduced, but the dust storage capacity decreases due to blockages
Solution Approach 1:
The diffuser is divided into multiple strips (at least two) arranged side by side, each with flow openings. This segmented structure distributes airflow more effectively across the bag interior, preventing dust accumulation and blockages while maintaining low device complexity
Solution Approach 2:
The diffuser strips incorporate flow openings (perforations or slots) that allow controlled airflow through the strips. This porous structure creates turbulence and distributes air evenly throughout the bag, preventing blockages and extending dust storage capacity
2Adaptability or versatility
If the diffuser strips are made movable relative to each other, then the adaptability to airflow patterns is improved, but the device complexity increases
Solution Approach 1:
The diffuser strips are designed to be movable relative to each other, allowing them to dynamically adjust to varying airflow patterns and dust accumulation conditions. This dynamic configuration optimizes airflow distribution without requiring complex control mechanisms
Applied Scientific Principles
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 diffuser design significantly extends the lifespan of the vacuum cleaner bag by improving dust distribution and preventing blockages, resulting in increased dust storage capacity and reduced pressure loss during operation.
Implementation Method 1
at least one diffuser (8) being disposed in the interior (20) of the block-base bag (1; 1'), which diffuser (8) consists of at least two individual strips of material (8) and/or sheet materials with oblong-shaped flow openings
