Removable Vacuum Dust Collector Compression for Cyclone Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collectors in vacuum cleaners face issues with dust circulation and low density storage, leading to frequent emptying and reduced efficiency due to dust blocking the cyclone separation mechanism and occupying excessive volume.
Innovation Solution
The implementation of compressing plates within the dust container that rotate to compress dust, reducing its volume and increasing storage capacity, while preventing dust from rising into the cyclone and scattering, thereby enhancing separation efficiency and extending emptying intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dust is stored in the dust container without compression, then the dust container can be emptied frequently to maintain separation efficiency, but the dust occupies excessive volume and requires frequent emptying
Solution Approach 1:
The patent changes the physical state of dust from loose to compressed by applying mechanical force through compressing plates. This parameter change in density allows the same volume to store more dust, reducing emptying frequency while maintaining separation efficiency.
Solution Approach 2:
The compressing plates perform periodic compression actions during vacuum operation. The plates move back and forth to continuously compress dust as it accumulates, maintaining high density storage capacity throughout the operating cycle.
2Reliability
If dust circulates along the inner walls during operation, then the cyclone separation effect deteriorates and unseparated dust is exhausted, but the dust settles at low density when operation stops
Solution Approach 1:
The compressing plates perform preliminary compression action on dust before it can settle loosely in the container. By compressing dust as it accumulates during operation, the system prevents low-density settling that would otherwise occur when operation stops.
Solution Approach 2:
The compression action continues throughout the vacuum operation rather than being intermittent. This continuous compression maintains dust in a high-density state, preventing the cycle of low-density settling and ensuring consistent separation efficiency.
3Quantity of substance
If the dust container is designed with large volume for storage, then dust can be stored longer, but the cyclone space is reduced and separation effectiveness decreases
Solution Approach 1:
The patent changes the density parameter of stored dust through compression. By increasing dust density in the container, the system can store more dust quantity in the same volume without expanding the container size, thus preserving cyclone space.
Solution Approach 2:
The patent addresses the volume contradiction by operating in the density dimension rather than the spatial dimension. Instead of increasing container volume to store more dust, the system compresses dust to increase its density, effectively storing more dust in the same spatial footprint.
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 effectively increases the dust storage capacity, improves dust separation efficiency, and reduces the frequency of emptying the dust container by maintaining a high dust density and preventing dust from interfering with the cyclone operation.
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
uses a difference in centrifugal force on the air and the dust (the cyclone principle) to separate the dust from the air
Implementation Method 3
The dust container (220) includes a pair of compressing plates (310, 320) that can operate to compress dust stored in the container to reduce the volume of the dust
Implementation Method 4
The driving mechanism (420) includes a rack bar (421) that is engaged to a pinion gear (422) that is coupled to a rotating shaft (311) of the first compressing plate (310). As the rack bar (421) moves back and forth, friction between the rack bar (421) and the pinion gear (422) causes the pinion gear (422) to rotate

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.
