Vacuum Cleaner Mist Dispenser for Dust Agglomeration and Odor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners often fail to completely remove dirt from the airstream, and the re-entrainment of separated dirt and fine dust plumes during emptying of the dirt cup pose challenges in maintaining cleanliness and odor control.
Innovation Solution
The integration of an odor neutralizer and dust plume abatement system within the vacuum cleaner, which includes a mist generator and aerosol dispenser, dispenses a mist into the working air path upstream of the dirt separation/collection module, utilizing the suction source to pull the mist into the module and neutralize odors while agglomerating dust, thereby improving dirt separation and reducing dust plumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a dirt separator is used to remove dirt from the working airstream, then dirt separation is improved, but fine dust may be re-entrained in the working airstream
Solution Approach 1:
The aerosol dispenser dispenses mist into the working air path upstream of the dirt separator before the air enters the separator. This preliminary action of adding mist to the airstream helps agglomerate fine dust particles before separation, preventing their re-entrainment downstream while maintaining effective dirt separation
2Ease of operation
If the dirt cup is removed from the vacuum cleaner for emptying, then ease of operation is improved, but plumes of fine dust may be released
Solution Approach 1:
The aerosol dispenser is positioned to dispense mist into the working air path upstream of the dirt separator, creating a mist environment in the dirt cup before emptying occurs. This preliminary action causes fine dust to agglomerate with the mist, significantly reducing dust plumes when the dirt cup is removed and emptied
3Manufacturing precision
If the aerosol dispenser is integrated upstream of the dirt separator, then dust agglomeration is improved, but device complexity increases
Solution Approach 1:
The aerosol dispenser system is integrated into the existing vacuum cleaner housing and working air path structure. The same aerosol dispenser mechanism serves multiple functions: dispensing mist upstream of the separator for dust agglomeration, and the system leverages the existing suction source and air flow paths, reducing the need for separate dedicated components and simplifying overall system integration
