Cleaning Robot Air Filter Vibration for Dust Buildup Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The air volume of cleaning robots decreases due to dust accumulation in HEPA filters, leading to reduced cleaning efficiency, and existing manual dust removal methods are inefficient and cause secondary pollution.
Innovation Solution
A cleaning system with a cleaning robot, a base station, and a dust cleaner that vibrates the air filter to shake off dust, and a collector to automatically remove and collect dust, ensuring continuous cleaning efficiency and preventing dust from adhering to the filter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual dust removal method is used, then dust can be removed from HEPA filter, but dust is raised during removal process causing secondary pollution and dirtying hands
Solution Approach 1:
The patent replaces manual mechanical cleaning with an automatic vibration-based dust removal system. The dust cleaner uses vibration to shake dust off the HEPA filter surface, eliminating the need for manual contact and water-based cleaning, thereby preventing secondary pollution and hand contamination while maintaining effective dust removal capability
Solution Approach 2:
The dust cleaner enables the HEPA filter to clean itself automatically through vibration-induced dust detachment. The system performs self-maintenance by shaking loose accumulated dust without requiring external manual intervention, making the cleaning process automated and hygienic
2Reliability
If HEPA filter is not cleaned, then cleaning robot structure remains intact, but dust removal efficiency decreases leading to reduced air volume
Solution Approach 1:
The dust cleaner enables automatic self-cleaning of the HEPA filter through vibration. The system maintains high dust removal efficiency by periodically shaking loose accumulated dust without requiring manual intervention or complex disassembly procedures, balancing reliability with operational simplicity
Solution Approach 2:
The patent employs vibration as the core mechanism for dust removal. The dust cleaner generates mechanical vibrations that shake the HEPA filter surface, causing accumulated dust to detach and fall into the dust collection box, thereby maintaining filter efficiency without complex cleaning procedures
3Productivity
If dust is not collected from dust box, then dust box structure remains simple, but dust accumulation impacts air filter vibration effect
Solution Approach 1:
The patent combines the dust collection function with the base station. When the cleaning robot returns to the base station, the collector automatically docks with the dust box and removes accumulated dust through suction. This integration maintains effective vibration performance by preventing dust overload while avoiding the need for complex onboard dust ejection 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 system effectively addresses the decrease in air volume and cleaning efficiency by automatically removing dust from the HEPA filter, maintaining the robot's performance and user experience while preventing dust from re-adhering.
Implementation Method 1
a dust cleaner, where the dust cleaner can vibrate the air filter to shake off the dust in the air filter
Implementation Method 2
a drawer, disposed inside the body and configured to generate an airflow, to draw garbage on the ground on a traveling path of the cleaning robot
Implementation Method 3
an air filter, disposed inside the dust box and configured to filter out dust in the airflow that is in the dust box and that is discharged outside the cleaning robot
Data Source
AI summary
A cleaning system and a base station. In a working process, an airflow is generated by a drawer, to draw garbage on the ground on a traveling path into a dust box. Before the airflow entering the dust box is discharged outside a cleaning robot, the airflow flows through an air filter, and dust carried by the airflow is filtered out under a filtering function of the air filter. When dust accumulation in the air filter needs to be cleaned or the dust box needs to be emptied, the air filter is driven by a dust cleaner to vibrate, so as to shake off dust in the air filter, and the garbage in the dust box is collected by using a collector of the base station.
