Removable Vacuum Dust Collector With Compression Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collectors in vacuum cleaners face issues with dust circulation and separation efficiency due to dust settling at low density, leading to frequent emptying and reduced operational efficiency.
Innovation Solution
A dust collector with compressing plates that reduce the volume of collected dust, preventing it from circulating and rising, thereby maintaining separation efficiency and increasing storage capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dust is stored in the dust container without compression, then the dust can be easily emptied, but the dust occupies excessive volume and settles at low density, requiring frequent emptying
Solution Approach 1:
The patent applies compression to change the physical state of dust from loose to compact form. The compressing plate exerts mechanical force to reduce dust volume and increase density, directly addressing the storage capacity issue while maintaining ease of emptying through the removable dust container design
2Productivity
If dust is allowed to circulate and rise in the dust container, then the dust remains loosely packed, but the cyclone separation effect deteriorates and unseparated dust is exhausted
Solution Approach 1:
The compressing plate performs preliminary compression of dust before it can circulate and rise to block the cyclone. By compacting dust at the bottom of the container, the system prevents dust circulation issues and maintains separation efficiency throughout operation
Solution Approach 2:
Compression changes the density parameter of stored dust, creating a compacted layer that prevents dust from rising and interfering with cyclone operation, thereby maintaining separation efficiency
3Volume of stationary object
If the dust container is designed with large volume for storage, then more dust can be collected, but the dust settles at low density and occupies the entire container volume
Solution Approach 1:
The compressing plate changes the density parameter of dust from low-density settled state to high-density compacted state. This allows the same container volume to hold significantly more dust, effectively increasing storage capacity without increasing physical container size
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 high-density storage, reducing the need for frequent emptying and improving overall vacuum 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 reduce the volume of collected dust

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.
