Vacuum Cleaner Filter Tapping Mechanism for Ash Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning systems for filtering members in ash-cleaners often degrade the filtering member and reduce its performance, and water-based systems increase weight while not effectively preventing ash and dust dispersion.
Innovation Solution
A hitting-type cleaning system with a lever mechanism and fork-type beating element that manually impacts the filtering member to dislodge ashes, using a suitable tank within the ash-cleaner to collect them, thereby extending the life and efficiency of the filtering member and ash-cleaner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If compressed air jets or axial compression systems are used to clean the filtering member, then cleaning effect is achieved, but the filtering member is degraded and its performance is reduced
Solution Approach 1:
The patent replaces the harmful mechanical compression systems with a gentle mechanical tapping system. Instead of using compressed air jets or axial compression that degrade the filter, the invention uses a series of light striking elements that tap the filter surface to dislodge ash. This substitution of the cleaning mechanism resolves the contradiction by achieving effective cleaning without degrading the filtering member's performance.
Solution Approach 2:
The patent changes the parameters of the cleaning action from high-force compression to low-force tapping. By using multiple light striking elements that deliver gentle taps rather than strong compression forces, the system achieves effective ash removal while preserving the filter's integrity and performance characteristics.
2Object-affected harmful factors
If water-based cleaning systems are used to prevent ash and dust dispersion, then ash containment is improved, but the ash-cleaner weight strongly increases
Solution Approach 1:
The patent extracts the water-based containment system and replaces it with a dry mechanical tapping system. By removing the water reservoir and pumping mechanisms, the invention eliminates the source of excessive weight while still preventing ash dispersion through the action of light striking elements that gently dislodge and contain ash particles.
Solution Approach 2:
The patent employs simple, lightweight striking elements that can be easily replaced if needed, rather than using a complex, heavy water-based system. These simple mechanical components achieve ash containment without the weight penalty of water reservoirs and associated mechanisms.
3Productivity
If strong compression or aggressive cleaning methods are used, then ash removal efficiency is improved, but the filtering member life is reduced
Solution Approach 1:
The patent uses periodic tapping action through multiple light striking elements that rhythmically tap the filter surface. This periodic gentle tapping effectively removes accumulated ash over time without the damaging effects of continuous strong compression, thereby maintaining both high ash removal efficiency and extended filter life.
Solution Approach 2:
The patent divides the cleaning function into multiple light striking elements distributed across the filter surface, rather than using a single strong compression point. This segmentation allows ash to be removed from multiple locations simultaneously through gentle taps, achieving efficient ash removal while preserving the filter's structural integrity and extending its service life.
