Eccentric Cyclone Dust Collector With Visible Fill Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collecting apparatuses in vacuum cleaners face issues with reduced suction force due to accumulation of large volumes of dirt, which is not easily visible, leading to increased size requirements for dust canisters to accommodate more dust, compromising compactness.
Innovation Solution
A dust collecting apparatus with a cyclone body arranged eccentrically within a dust canister, featuring a transparent common portion for visibility and a helical guide colored differently to facilitate observation of dirt flow, allowing for enhanced visibility and increased dust collection capacity without enlarging the apparatus size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the dust canister is made larger to increase dust collection capacity, then the amount of dust collected is improved, but the size of the dust collecting apparatus increases
Solution Approach 1:
The cyclone body is positioned eccentrically within the dust canister, allowing the cyclone chamber to be nested within the dust collection chamber. This nested arrangement enables the dust collection chamber to utilize the space around the cyclone body, thereby increasing dust collection capacity without proportionally increasing the overall apparatus size.
Solution Approach 2:
By arranging the cyclone body eccentrically rather than centrally, the design utilizes the three-dimensional space more efficiently. The asymmetric positioning creates optimal use of available volume, allowing larger dust collection capacity within constrained external dimensions.
2Device complexity
If the cyclone chamber is positioned centrally in the dust collection chamber, then the structure is simplified, but the dust collection capacity is limited due to space constraints
Solution Approach 1:
The cyclone body is positioned eccentrically within the dust canister rather than at the center. This asymmetric arrangement optimizes the available space for dust collection, allowing the dust collection chamber to maximize its capacity while maintaining relatively simple structural elements.
3Quantity of substance
If a large volume of dirt accumulates in the cyclone chamber, then the dust collection capacity is utilized, but the suction force decreases and the user cannot determine when to empty it
Solution Approach 1:
The common portion of the cyclone body is made of transparent material, allowing users to visually observe the dirt accumulation level in the cyclone chamber. This transparency enables users to determine when the chamber needs emptying, preventing suction force degradation from excessive accumulation.
Solution Approach 2:
The transparent common portion provides visual feedback about the dirt accumulation state in real-time during operation. This feedback mechanism allows users to monitor and maintain optimal operating conditions without disconnecting the dust collecting apparatus from the cleaner body.
4Difficulty of detecting and measuring
If the cyclone body is made entirely of transparent material, then visibility is improved, but the manufacturing cost and complexity increase
Solution Approach 1:
Only the common portion of the cyclone body that interfaces with the dust canister is made of transparent material, while other portions can be made of standard opaque materials. This localized transparency provides the necessary visibility function without requiring the entire cyclone body to be manufactured from transparent materials, thus reducing manufacturing complexity and cost.

Function Achieved in This Case
Enables direct observation of dirt accumulation without disconnection, maintaining suction force and compactness by allowing larger dust collection capacity within the same size constraints.
Implementation Method 1
separates the dust entrained in the air using a difference of centrifugal force between the air and the dust by rotating the air

AI summary
A dust collecting apparatus which is removably connected to a cleaner body is provided. The apparatus includes a cyclone body which forms a cyclone chamber and is in fluid communication with an air inlet passage on one side thereof; an exit pipe which is protruded from a bottom of the cyclone body to an upper side of the cyclone chamber; and a dust canister body which forms a dust collection chamber between the cyclone body and the dust canister body. The cyclone body is arranged eccentrically within the dust collection chamber so that a portion of the cyclone body has a common portion in contact with a portion of the dust canister body. The common portion is made of transparent materials to see through the cyclone chamber.
