Vacuum Cleaner Dust Collector with Compression Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face challenges in providing users with convenience during the dust discharging process, as they often scatter dust or require complex procedures, and current dust collectors are inefficient in separating and discharging large and fine dust simultaneously.
Innovation Solution
A dust collector with separate units for large and fine dust, utilizing cyclones for separation and a compression device that rotates along the outer surface of the dust containers to compress and facilitate simultaneous discharge of collected dust, ensuring it is not scattered and can be easily emptied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If dust is collected in a single dust container, then the device complexity is reduced, but the ability to separate and discharge large and fine dust simultaneously is worsened
Solution Approach 1:
The dust container is divided into two separate dust storing units: a first dust storing unit for collecting large dust particles and a second dust storing unit for collecting fine dust particles. This segmentation allows different types of dust to be stored separately and discharged simultaneously through different discharge openings, resolving the contradiction between structural simplicity and dust separation capability.
2Ease of operation
If a compression device is added to compress dust, then the ease of operation during dust discharge is improved, but the device complexity increases
Solution Approach 1:
The compression device is designed to be automatically activated during the dust discharge process. When the discharge openings are opened, the compression device automatically compresses the dust in both storing units, eliminating the need for manual compression operations and improving ease of operation while keeping the automation level moderate.
3Device complexity
If dust is discharged without compression, then the device complexity is reduced, but the productivity during dust disposal is worsened
Solution Approach 1:
The compression device performs dust compression in advance before the dust is discharged from the container. By compressing the dust while it is still stored in the dust storing units, the system prepares the dust for efficient discharge, increasing productivity by enabling faster and more complete dust removal without requiring complex discharge mechanisms.
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 solution effectively prevents dust scattering and simplifies the discharge process by compressing and collecting both large and fine dust within the dust collector, allowing for efficient and convenient disposal without scattering or unexpected discharge.
Implementation Method 1
a first dust storing unit formed in a hollow cylindrical shape between an inner circumferential surface of a first dust container and an outer circumferential surface of a second dust container located in the first dust container, and configured to collect dust firstly-separated from air by a first cyclone
Implementation Method 2
a second dust storing unit disposed to be surrounded by the first dust storing unit, and configured to collect fine dust secondly-separated from the air by second cyclones, located above the first cyclone, into a space formed by the second dust container
Implementation Method 3
a compression device that is at least partly rotatably, and configured to reciprocatingly rotate along the outer circumferential surface of the second dust container to compress the dust collected in the first dust storing unit

AI summary
A dust collector disclosed herein includes a first dust storing unit to collect dust firstly-separated from air by a first cyclone, a second dust storing unit to collect fine dust secondly-separated from the air by second cyclones located above the first cyclone, a lower cover part coupled to a first dust container to form a bottom surface of the first dust storing unit and the second dust storing unit, and rotatable based on the hinge to simultaneously open the first and second dust storing units, such that the dust and the fine dust are simultaneously discharged, and a compression device rotatably connected to the lower cover part so as to rotate in a reciprocating manner to compress the dust collected in the first dust storing unit.
