1. A volatile liquid dispensing system comprising:
a reservoir for holding a supply of volatile liquid;
a pressurized gas source;
an atomizer comprising a chamber, an outlet nozzle fluidly coupleable to the chamber, and a venturi assembly positioned within the chamber,
wherein the venturi assembly comprises a first orifice fluidly coupleable to the pressurized gas source through a flow path that includes a venturi nozzle, and a second orifice fluidly coupleable to the reservoir,
wherein the atomizer is configured to cause, responsive to pressurized gas from the pressurized gas source flowing through the venturi nozzle, extraction of a portion of the supply of volatile liquid through the second orifice, atomization of the portion of the supply of volatile liquid within the chamber and/or the outlet nozzle, and expelling of the atomized liquid through the outlet nozzle;
an electrical power source;
a fan configured to be powered by the electrical power source in order to generate a flow of air;
a duct positioned to transfer the flow of air from the fan to an exit of the duct that is positioned adjacent the outlet nozzle, such that the flow of air exiting the duct can be applied to the atomized liquid expelled through the outlet nozzle to disperse the atomized liquid;
a controller configured to repeatedly automatically activate and deactivate the pressurized gas source and the fan such that, responsive to a trigger event occurring, the controller will implement a dispensing process that causes:
activation of both the pressurized gas source and the fan, to atomize the portion of the supply of volatile liquid and to disperse the atomized liquid;
deactivation of the pressurized gas source while keeping the fan activated for a period of time, to continue dispersing the atomized liquid after the compressed gas source has been deactivated; and
deactivation of the fan after the period of time,
wherein the controller is configured to repeat the dispensing process responsive to an additional trigger event occurring,
wherein the trigger event and the additional trigger event each comprises at least one of a timer elapsing, a motion detection, or a light detection; and
a housing that contains at least the controller, the reservoir, the pressurized gas source, the atomizer, the fan, and the duct.
