Vacuum Cleaner Rotating Rib Filter Cleaning to Reduce Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners face inefficiencies in dust collection due to dust accumulation on filters, which blocks airflow, increases fan load, and causes visual unappeal, with existing cleaning mechanisms often failing to effectively redirect dust into storage units, leading to scattering and reduced cleaning performance.
Innovation Solution
A vacuum cleaner design featuring a multi-cyclone dust collector with a mesh filter positioned horizontally and cleaning ribs that rotate to collect dust from the filter surface, directing it into a dust storage unit, and a rotation unit that compacts and rolls the dust to prevent backward flow and scattering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a filter is used to separate dust from air in the cyclone, then dust separation efficiency is improved, but dust accumulates on the filter blocking airflow and increasing fan load
Solution Approach 1:
The patent extracts the dust accumulation problem from the filter by introducing a separate dust storage chamber. The filter is positioned horizontally so dust falls into the chamber below, separating the dust storage function from the filtration function. This prevents dust from blocking the filter while maintaining separation efficiency.
Solution Approach 2:
The patent changes the filter orientation from vertical to horizontal, utilizing the vertical dimension for dust gravity separation into the storage chamber. This dimensional change allows dust to be collected below the filter without interfering with the filtration process, resolving the contradiction between separation efficiency and airflow throughput.
2Ease of operation
If a cleaning unit is used to remove dust from the filter, then filter cleanliness is improved, but dust accumulates on the cleaning unit instead of moving to storage
Solution Approach 1:
The patent applies preliminary action by positioning the filter horizontally before the cleaning unit operates. This orientation ensures that when the cleaning unit removes dust from the filter, gravity naturally directs the dust downward into the storage chamber, preventing accumulation on the cleaning unit itself.
3Measurement precision
If multiple cyclones are used to separate particles, then dust collection capability is improved, but air flow patterns create eddies that obstruct dust introduction to storage unit
Solution Approach 1:
The patent extracts the dust collection function from complex multi-cyclone systems by using a single cyclone with a horizontally positioned filter. The simplified design directs air flow more straightforwardly to the dust storage chamber, reducing eddy formation while maintaining effective particle separation.
4Productivity
If dust is collected in a dust storage unit, then dust collection efficiency is improved, but dust may float backward or scatter out to block filter holes
Solution Approach 1:
The patent applies the anti-weight principle by using the horizontal filter orientation to counteract dust backward flow. The horizontal positioning creates a gravity-based barrier that prevents dust in the storage chamber from floating upward and blocking the filter, while the filter itself acts as a physical barrier against scatter out.

AI summary
The present disclosure relates to a vacuum cleaner for separating and collecting dust and other contaminants by using a multi-cyclone and a mesh filter, including a cleaning unit for sweeping dust and foreign materials attached to the mesh filter along an outer circumferential surface of the mesh filter, and a rotation unit coupled to the cleaning unit for rotating the cleaning unit relative to the mesh filter, whereby the cleaning unit can clean a surface of the filter automatically or manually during an operation of the cleaner, so that the filter surface can be kept clean, and a load on a fan unit caused due to foreign materials or dust can be reduced.
