Robot Vacuum Dust Canister Structure for Complete Dust Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robot vacuum dust canisters often experience bottlenecking and failure to discharge dust due to their structural design, particularly in the cyclone chamber, leading to incomplete cleaning and reduced suction efficiency.
Innovation Solution
The dust canister features a first chamber with an inclined surface and a rib to prevent dust from getting stuck, a cyclone unit with a centrifugal separator, and a partition with cyclone holes to guide dust from the cyclone chamber to the first chamber, ensuring smooth discharge through automatic dust discharge mode without reducing suction force or capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dust canister uses a conventional structure with a cyclone chamber, then dust separation is achieved, but dust discharge fails due to bottlenecking in the lower area
Solution Approach 1:
The dust canister is divided into multiple chambers (first chamber with inclined surface, second chamber with cyclone unit, third chamber) to segment the dust discharge path. This segmentation allows dust to be discharged through multiple routes, preventing bottlenecking in any single area and improving overall discharge reliability.
Solution Approach 2:
The patent introduces a third chamber that provides an additional discharge dimension. Dust can be discharged not only from the first chamber but also from the third chamber, creating a multi-dimensional discharge system that eliminates the bottlenecking problem caused by the narrow lower area of conventional single-chamber designs.
2Ease of operation
If the dust canister uses an automatic dust discharge mode, then manual disassembly is eliminated, but dust remains trapped due to structural bottlenecks
Solution Approach 1:
The multi-chamber segmentation enables the automatic dust discharge mode to work effectively by providing multiple discharge paths. The first chamber handles initial dust collection, the cyclone unit separates dust from air, and the third chamber provides additional discharge capacity, ensuring complete dust removal without manual intervention.
Solution Approach 2:
The cyclone unit acts as an intermediary between dust collection and discharge. It separates dust from air using centrifugal force and directs dust to appropriate chambers for discharge, enabling the automatic discharge mode to function reliably without requiring user disassembly of the canister.
3Productivity
If the dust canister maintains full capacity for suction, then cleaning efficiency is high, but dust discharge becomes problematic due to space constraints
Solution Approach 1:
The dust canister is segmented into multiple functional chambers that operate simultaneously. The first chamber collects dust during suction, the cyclone unit continuously separates dust from air, and the third chamber stores and discharges dust. This segmentation allows the canister to maintain full suction capacity while ensuring reliable dust discharge through multiple pathways.
Solution Approach 2:
The cyclone unit operates continuously during suction to separate dust from air, and the multi-chamber design ensures continuous dust discharge capability. The system maintains uninterrupted dust collection and discharge operations, preserving full suction productivity while preventing dust accumulation and discharge failures.

AI summary
A robot vacuum comprises a main body including a suction part for suctioning dust, and a dust canister, attachable to and detachable from the main body, and which separates dust from the air suctioned through the suction part and stores same. The dust canister includes: a first chamber which separates dust from the air flowing in from the suction part and storing same, and which includes an inclined surface so that the lower area thereof becomes narrower than the upper area thereof; and a second chamber which includes a cyclone unit and which separates dust from the air flowing in from the first chamber and stores same, and the first chamber can further include ribs formed along the inclined surface to facilitate discharge of dust so as to prevent the dust stored in the first chamber from becoming stuck, due to bottlenecking, in the lower area of the first chamber.
