Cyclone Cleaner Movable Dust Compression Frame to Prevent Blockage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners face issues with dust compression efficiency due to the dust compression part being located higher than the opening, reducing the internal space for dust separation and causing dust accumulation, which hinders smooth movement and blocks the opening.
Innovation Solution
A cleaner design with a movable part that includes a frame with inclined bodies forming an air flow path, allowing dust to fall into the dust bin even when the movable part is operated downward, and preventing air from directly moving into the air flow path, ensuring smooth operation and effective dust compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the dust compression part is located higher than the opening at standby position, then the cleaner structure is simplified, but the internal space for dust separation is reduced and dust compression performance deteriorates
Solution Approach 1:
The dust compression part is designed to be movable between a standby position (higher than the opening) and a dust compression position (lower than the opening). This dynamic positioning allows the structure to maintain simplicity at standby while providing sufficient compression space when needed, resolving the contradiction between structural simplicity and functional performance.
2Volume of moving object
If the dust compression part is located higher than the opening, then the structure is compact, but the vertical movement distance for dust compression is reduced
Solution Approach 1:
The movable dust compression part transitions from a higher standby position to a lower compression position, maximizing the vertical movement distance within the compact housing. This dynamic range enables effective dust compression while maintaining overall structural compactness.
3Ease of operation
If the dust compression part moves in contact with the inner circumferential surface, then the surface is cleaned, but dust may be caught between them causing movement obstruction
Solution Approach 1:
A seal member (flexible element) is provided between the dust compression part and the inner circumferential surface. This seal member enables effective cleaning contact while preventing dust from being caught, ensuring smooth and reliable movement of the dust compression part.
4Productivity
If the movable part is operated downward during suction, then dust compression is enhanced, but dust may accumulate on the upper side blocking movement
Solution Approach 1:
The seal member extracts the harmful effect of dust accumulation by creating a sealed environment that prevents dust from adhering to the upper side of the movable dust compression part. This ensures reliable movement while maintaining high dust compression efficiency.
