Removable Vacuum Dust Collector With Rotating Dust Compression
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 blocks the cyclone, reducing separation efficiency and requiring frequent emptying.
Innovation Solution
A dust collector with compressing plates that rotate within the dust container to compress dust, reducing 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 in the dust container using conventional methods, then dust is stored in the container, but the dust settles at the bottom and blocks the cyclone, reducing separation efficiency
Solution Approach 1:
The patent introduces a rotating compressing plate that dynamically changes the dust storage state from static settling to dynamic compression. The compressing plate rotates to continuously compress dust particles, preventing them from settling and blocking the cyclone, thereby maintaining separation efficiency while increasing storage capacity.
Solution Approach 2:
The patent changes the physical state parameter of dust from low-density settled state to high-density compressed state. By applying mechanical compression through the rotating compressing plate, the dust density increases, allowing more dust to be stored in the same container volume without blocking the cyclone separation mechanism.
2Quantity of substance
If dust is stored in the dust container, then storage capacity is utilized, but the dust occupies excessive volume at low density, requiring frequent emptying
Solution Approach 1:
The patent applies mechanical compression to change the density parameter of stored dust from low to high. The rotating compressing plate continuously compresses dust particles, reducing the volume they occupy and increasing the effective storage capacity of the container, thereby reducing the frequency of emptying operations.
Solution Approach 2:
The compressing plate operates continuously during dust collection, maintaining constant compression on the dust particles. This continuous useful action ensures that dust remains in a compact, high-density state throughout the collection process, maximizing storage capacity and minimizing emptying frequency.
3Ease of manufacture
If the dust container is designed with a fixed structure, then manufacturing is simple, but the dust circulation and low density storage reduce collection efficiency
Solution Approach 1:
The patent transforms the fixed dust container structure into a dynamic system by adding a rotating compressing plate. This dynamic element continuously compresses dust particles, preventing circulation and blocking, thereby significantly improving dust collection efficiency while maintaining relatively simple container manufacturing.
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
The compressing mechanism enhances dust collection efficiency by maintaining a high-density dust state, reducing the need for frequent emptying and improving the overall performance of the vacuum cleaner by minimizing dust circulation and maximizing storage capacity.
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 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.
