Removable Vacuum Dust Collector With Rotating Plate Compaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collectors in vacuum cleaners face issues with dust circulation and low density storage, leading to inefficient separation and frequent emptying, as collected dust settles at the bottom and circulates within the container, reducing the cyclone's separation efficiency and requiring frequent emptying.
Innovation Solution
The implementation of a dust collector with compressing plates that rotate within the dust container to compress dust, reducing its volume and increasing storage capacity, while preventing dust from rising into the cyclone and improving separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If dust is collected and stored in the dust container, then the dust collecting capacity increases, but the dust settles at the bottom and circulates within the container, causing the cyclone separation efficiency to deteriorate
Solution Approach 1:
The patent introduces a rotating compressing plate that dynamically moves within the dust container to compress dust during vacuum operation. This dynamic compression prevents dust from settling and circulating at the bottom, maintaining cyclone separation efficiency while increasing dust storage capacity. The compressing plate rotates to apply mechanical force that densifies dust particles without blocking the cyclone airflow path.
Solution Approach 2:
The patent changes the physical state of dust by compressing it to higher density using the rotating compressing plate. This parameter change (from low-density settled dust to high-density compressed dust) allows more dust to be stored in the same container volume while preventing the dust from rising into the cyclone, thus maintaining separation efficiency.
2Quantity of substance
If dust is stored in the dust container, then the dust collecting capacity increases, but the collected dust occupies excessive volume and settles at the bottom, requiring frequent emptying
Solution Approach 1:
The rotating compressing plate continuously or periodically compresses dust during vacuum operation, dynamically reducing dust volume as dust accumulates. This prevents dust from occupying excessive space and eliminates the need for frequent emptying, as the compression mechanism maintains optimal storage density throughout operation.
Solution Approach 2:
The compressing plate operates continuously or periodically during vacuum operation to continuously compress dust. This continuous useful action ensures dust is constantly densified, maximizing storage capacity and eliminating idle time for frequent emptying operations.
3Device complexity
If the dust container is designed with a fixed volume, then the device complexity is reduced, but the dust storage capacity is limited and requires frequent emptying
Solution Approach 1:
The patent maintains a simple fixed-volume dust container structure but adds a rotating compressing plate mechanism that dynamically increases effective storage capacity by compressing dust in-place. This approach increases dust storage capacity without requiring a larger or more complex container structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances the dust collecting capacity by compressing dust to a higher density, reducing the frequency of emptying and maintaining efficient vacuum operation by preventing dust from entering the cyclone, thus improving overall dust collection and cyclone performance.
Implementation Method 1
The upper portion of the dust container 11 forms a cyclone that uses a difference in centrifugal force on the air and the dust (the cyclone principle) to separate the dust from the air
Implementation Method 2
a dust collector with compressing plates that rotate within the dust container to compress dust, reducing its volume and increasing storage capacity

AI summary
A vacuum cleaner includes a dust collector that compresses dust stored inside a dust container to minimize the volume of the dust. The dust collector would include one or more pressing plates that are used to compress the dust stored in dust collector. Various methods are used to control movements of the movable pressing plates to facilitate the compression operations. Also, various methods are used to determine when the dust collector is full and needs to be emptied.
