Vacuum Dust Chamber Guide Rib for Anti-Entanglement Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners face issues with rubbish entanglement and dispersion in the dust collecting chamber, leading to reduced suction power and cumbersome operation, as well as frequent emptying requirements.
Innovation Solution
The cleaner incorporates a housing with a filtering member and a main body that includes a dirt removal member, an opening and closing device, and a connecting frame with guide ribs to prevent rubbish entanglement and allow sequential accumulation in the dust collecting chamber, enhancing usability by facilitating neat discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rubbish is filtered out by a porous filter unit or cyclone-type dust collector, then rubbish is separated from air, but rubbish becomes tangled inside the dust collecting chamber requiring manual separation
Solution Approach 1:
The patent implements a self-cleaning mechanism where a brush assembly automatically removes rubbish from the dust collecting chamber walls and filter surfaces. The brush is driven by a motor and rotates to scrape accumulated rubbish into a collection container, eliminating the need for manual disassembly and cleaning by the user. This self-service approach resolves the contradiction by maintaining high rubbish separation efficiency while automating the maintenance process.
Solution Approach 2:
The patent introduces a brush assembly as an intermediary mechanism between the dust collecting chamber and the user. Instead of requiring direct user contact with tangled rubbish for cleanup, the brush assembly acts as a mediator that automatically transfers rubbish from the chamber walls to a collection container, simplifying user interaction while maintaining effective rubbish separation.
2Reliability
If rubbish rotates inside the dust collecting chamber during cyclone flow, then rubbish is filtered out, but rubbish disperses and accumulates throughout the chamber requiring frequent emptying
Solution Approach 1:
The patent implements an automatic rubbish collection system where a brush assembly continuously sweeps rubbish from the dust collecting chamber walls into a collection container. This self-service mechanism prevents rubbish from dispersing and accumulating throughout the chamber by actively directing it to a designated collection area, thereby reducing the frequency of manual emptying while maintaining effective filtration.
Solution Approach 2:
The patent applies preliminary action by using the brush assembly to continuously sweep and collect rubbish during the filtration process itself. Rather than waiting for the chamber to fill up with dispersed rubbish, the system proactively removes rubbish as it accumulates on the walls, preventing widespread dispersion and reducing the need for frequent manual emptying operations.
3Power
If a small amount of rubbish clogs the inlet or outlet of the dust collecting chamber, then suction power is reduced, but frequent monitoring and emptying is required
Solution Approach 1:
The patent implements a self-maintaining system where the brush assembly automatically removes rubbish from critical areas such as the inlet and outlet of the dust collecting chamber. This prevents clogging that would reduce suction power, eliminating the need for frequent user monitoring and intervention to maintain optimal performance.
Solution Approach 2:
The patent incorporates a sensor that detects the amount of rubbish in the collection container and provides feedback to the control unit. When the container is full or when clogging is detected, the system automatically alerts the user or activates the brush assembly to clear the blockage, ensuring suction power is maintained without requiring constant user monitoring.
