Abstract
A mist generating system for a cleaning implement is adapted to generate a finely atomized liquid mist for suppressing dust, allergens, and other airborne particulates. The mist generating system can be adapted to fit many cleaning implements such as vacuum cleaners, wet extraction cleaners, floor mops, and dusters to suppress airborne dust and particulates generated during operation and the cleaning process.
Claims20
A cleaning implement comprising:
- a housing for movement over a surface to be cleaned;
- an electronic controller;
- and
- a mist generating system mounted to the housing and comprising:
- a supply tank;
- an atomizing nozzle comprising:
- a transducer probe;
- a liquid inlet fluidly coupled with the supply tank;
- and
- a nozzle outlet fluidly coupled to the liquid inlet via a chamber adapted to hold a volume of liquid from the supply tank;
- and
- at least one piezoelectric element in register with the transducer probe and operably connected to the electronic controller, wherein the at least one piezoelectric element is configured to convert a signal received from the electronic controller into mechanical vibration that is transmitted to the transducer probe to atomize the volume of liquid in the chamber to generate atomized liquid mist;
- wherein the atomized liquid mist is dispensed through the nozzle outlet.
