Solution Overview
Problem
Existing robotic vacuum cleaners face performance reduction due to filter clogging, requiring manual cleaning of the second separating unit, which is inconvenient and unhygienic for users.
Innovation Solution
An automatic cleaning device is integrated on the second separating unit to remove deposited dust and dirt particles, preventing clogging and maintaining suction power without user intervention, utilizing translational or rotary movements and driven by either the primary or secondary drive device, or via a charging station interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a second separating unit (filter element) is used to separate fine dust particles, then cleaning performance is improved, but the filter element becomes clogged with dust particles, reducing suction air volume flow and cleaning performance
Solution Approach 1:
The filter element performs self-cleaning by utilizing the suction air flow that passes through it. The suction air flow automatically removes dust particles from the filter element surface, enabling the filter to maintain its separation function without external intervention or manual cleaning.
Solution Approach 2:
The invention uses the suction air flow (gas flow) generated by the vacuum robot to clean the filter element. The moving suction air flow acts as a pneumatic cleaning mechanism that removes dust particles from the filter surface, preventing clogging while maintaining separation efficiency.
2Reliability
If manual cleaning of the second separating unit is required, then filter performance can be restored, but user convenience deteriorates and maintenance becomes unhygienic
Solution Approach 1:
The filter element automatically cleans itself using the suction air flow, eliminating the need for manual user intervention. This self-service mechanism prevents dust accumulation on the filter while avoiding direct contact between the user and dust particles, thereby maintaining filter performance and improving user convenience.
