Abstract
A vacuum cleaner includes a device for dispensing atomized liquid, the device having a reservoir for holding liquid and an ultrasonic transducer arranged to atomize the liquid in the reservoir. An airflow is created through the reservoir via the exhaust gasflow from the vacuum cleaner, the airflow carrying the atomized liquid via an elongate tube to dispensing outlet provided on a cleaning head of the vacuum cleaner. The ultrasonic transducer is simple and inexpensive, yet is able to reliably atomize the liquid for dispensing.
Claims15
A vacuum cleaner comprising a device for dispensing atomized liquid, the device comprising a tubular reservoir having a bottom portion for holding liquid and an ultrasonic transducer arranged to atomize the liquid in the reservoir, the vacuum cleaner further comprising a fan for creating an airflow through the reservoir to carry the atomized liquid through a dispensing outlet of the vacuum cleaner, wherein the reservoir comprises a boundary wall which extends inside the reservoir and divides the reservoir into two compartments, the boundary wall terminating above the bottom portion of the reservoir, the ultrasonic transducer located in the reservoir below the boundary wall, and the fan arranged to create an airflow through one compartment which passes under the boundary wall into the other compartment and over the surface of the liquid in the bottom portion.
