Dust scraping device and cleaning apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The dust cup of handheld cleaning apparatuses becomes difficult to clean due to hair and debris winding around the outer circumference of the cyclone separation unit, making it challenging to remove and clean effectively.
Innovation Solution
A dust scraping device with a dust scraping member is integrated into the dust cup, featuring a connection portion extending in the removal direction of the cyclone separation unit and a dust scraping portion that slides perpendicular to the removal direction, allowing for the removal of debris from the outer side of the cyclone separation unit when it is detached from the dust cup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cyclone separation unit is made removable for easy cleaning, then the ease of operation is improved, but debris accumulates on the outer side of the cyclone separation unit making cleaning difficult
Solution Approach 1:
The dust scraping member is pre-installed on the dust cup to automatically scrape debris from the cyclone separation unit during its removal process, before manual cleaning occurs. This preliminary scraping action prevents debris accumulation that would otherwise hinder cleaning effectiveness.
Solution Approach 2:
The dust scraping member enables the dust cup to clean itself by scraping debris from the cyclone separation unit during removal. The structure performs self-cleaning functionality without requiring additional manual intervention or separate cleaning tools.
2Ease of operation
If a dust scraping member is added to scrape debris, then the cleaning effectiveness is improved, but the device complexity increases
Solution Approach 1:
The dust scraping member serves multiple functions: it scrapes debris from the cyclone separation unit, guides the separation unit during removal, and prevents debris from falling into unwanted areas. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The dust scraping member is designed as a flexible elastic component that can deform during the removal process. This flexibility allows it to adapt to the cyclone separation unit's surface while maintaining structural simplicity and avoiding complex rigid 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 dust scraping device effectively scrapes off debris from the cyclone separation unit, improving the cleaning efficiency and ease of maintenance by ensuring that the dust cup can be cleaned thoroughly without interference from wound-on debris.
Implementation Method 1
a dust scraping portion extending to an interior of the dust cup in a direction perpendicular to the removal direction and slidably abutting against the cyclone separation unit

AI summary
A dust scraping device for a cleaning apparatus includes a dust cup and a removable cyclone separation unit arranged in the dust cup. The dust scraping device includes a dust scraping member. The dust scraping member has a connection portion extending in a removal direction of the cyclone separation unit, and a dust scraping portion extending to an interior of the dust cup in a direction perpendicular to the removal direction and slidably abutting against the cyclone separation unit. The dust scraping device is mounted at the dust cup, and the dust scraping portion scrapes off at least part of debris on an outer side of the cyclone separation unit when the cyclone separation unit is removed from the dust cup.
