- An air freshener atomizer, comprising: - an injector unit; - a compressor driving air into said injector unit through an air injection tube; - a container containing a load which is a solution to be dispensed, - a first atomizing chamber having an input end and an output end; and - a second atomizing chamber having an input end in fluidic communication with said output end of the first atomizing chamber and an output end having an atomizing nozzle; - a liquid injection tube arranged in the injector unit in fluidic communication with said load; such that the load is combined with said air driven by the compressor by means of the Venturi effect and atomized in the injector unit, the atomized load goes into the first atomizing chamber through the input end thereof, passes there through, then goes into the second atomizing chamber through the input end thereof, and then the atomized load exits the air freshener atomizer through said atomizing nozzle; characterized in that: - said compressor is a heating compressor driving heated pressurized air into the injector unit through said air injection tube; - said first atomizing chamber is a tapered conical first atomizing chamber having a decreasing internal volume distribution from said input end to said output end, and is arranged in a horizontal position in alignment with the air injection tube; - said second atomizing chamber is a vertical second atomizing chamber fluidically communicating with an upper zone of a narrowest end of the tapered conical first atomizing chamber and having at an upper region thereof the atomizing nozzle; and - a return conduit is provided fluidically communicating a lower zone of a widest end of the first atomizing chamber with said container for returning remaining wet particles to the container; whereby the atomized load is a potentially flammable water alcohol solution, which is converted into a semi-dry gasified load in the first atomizing chamber and said semi-dry gasified load is received and converted into a non-flammable dry gasified product in the vertical second atomizing chamber. - an injector unit; - a compressor driving air into said injector unit through an air injection tube; - a container containing a load which is a solution to be dispensed, - a first atomizing chamber having an input end and an output end; and - a second atomizing chamber having an input end in fluidic communication with said output end of the first atomizing chamber and an output end having an atomizing nozzle; - a liquid injection tube arranged in the injector unit in fluidic communication with said load; - said compressor is a heating compressor driving heated pressurized air into the injector unit through said air injection tube; - said first atomizing chamber is a tapered conical first atomizing chamber having a decreasing internal volume distribution from said input end to said output end, and is arranged in a horizontal position in alignment with the air injection tube; - said second atomizing chamber is a vertical second atomizing chamber fluidically communicating with an upper zone of a narrowest end of the tapered conical first atomizing chamber and having at an upper region thereof the atomizing nozzle; and - a return conduit is provided fluidically communicating a lower zone of a widest end of the first atomizing chamber with said container for returning remaining wet particles to the container;
