Abstract
An improved aerosol dispensing apparatus includes an aerosol container, a discharge piece movably mounted to the aerosol container, a metering valve mounted within the discharge piece, a battery, and an electronically controlled flow control valve. The flow control valve is electronically connected to the battery and is in fluid communication with the metering valve. The metering valve is movable between an open position wherein a volume of an aerosol formulation is directed from the aerosol container through the metering valve to the electronically controlled flow control valve, and a closed position wherein the aerosol formulation is not permitted to flow through the metering valve. The electronically controlled flow control valve is configured to precisely control a flow of the aerosol formulation outward of the discharge piece.
