Vacuum Cleaner Dust Compressor and Lifter for Dispersion-Free Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held vacuum cleaners have issues with dust dispersion when the dust container is opened, and dust can be stuck to the outer surfaces of the cyclonic separating apparatus, making it difficult to clean and potentially harmful to users.
Innovation Solution
The cleaner design includes a cyclonic airflow system with a dual cyclone configuration and a dust container with a body cover that prevents dust dispersion and allows for easy dust removal, featuring a cleaning compressor that compresses dust and a lever mechanism for efficient dust collection and disposal without disturbing the cyclonic airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dust container is opened to remove collected dust, then dust can be removed from the container, but dust may be released and harm user health or contaminate the surroundings
Solution Approach 1:
The cyclonic separating apparatus is positioned above the dust container opening, and dust is compressed against the outer surface of the cyclonic separating apparatus before the dust container is opened. This preliminary compression and positioning of dust prevents it from dispersing into the air when the container is opened, allowing safe dust removal while protecting user health.
2Quantity of substance
If dust is collected in the dust container, then dust can be stored, but dust may be stuck to the outer surface of the cyclonic separating apparatus and be hard to remove
Solution Approach 1:
The cyclonic separating apparatus has a curved outer surface that allows dust to be compressed and contained smoothly. The curved geometry prevents dust from adhering strongly to the surface while maintaining effective dust collection, making it easier to remove stuck dust without damaging the separating apparatus.
3Volume of stationary object
If the dust container capacity is increased, then more dust can be stored, but the cyclonic airflow may be disturbed
Solution Approach 1:
The dust container is divided into an inner dust container and an outer dust container, with the cyclonic separating apparatus positioned between them. This segmentation allows the inner container to maintain optimal volume for effective cyclonic airflow while the outer container provides additional storage capacity, thus increasing total dust container capacity without disturbing the cyclonic airflow in the inner container.

Function Achieved in This Case
The solution effectively prevents dust dispersion during removal, allows for easy cleaning of stuck dust, and ensures efficient dust collection and disposal, maintaining the cyclonic airflow and extending the dust container's capacity without frequent emptying.
Implementation Method 1
a dust separation unit comprising at least one cyclone for separating dust from suctioned air by centrifugation
Implementation Method 2
a cleaning compressor reciprocating between the flow space and the dust storage, wherein the cleaning compressor comprises a base member that defines a closed loop on a surface transverse to the airflow axis
