1. A dry mist generating apparatus, comprising:
a wheeled cart;
a housing positioned within the wheeled cart, wherein a base of the housing is positioned at a first height;
a first liquid holding tank within the wheeled cart, wherein a base of the first liquid holding tank is positioned at a second height, which is higher than the first height, the first liquid holding tank comprising a first liquid sensor and a second liquid sensor;
a second liquid holding tank within the wheeled cart, wherein a base of the second liquid holding tank is positioned at the second height, which is higher than the first height, the second liquid holding tank comprising a first liquid sensor and a second liquid sensor;
at least one pipe for coupling the first liquid holding tank and the second liquid holding tank to the housing;
at least one electronic valve coupled to the at least one pipe for controlling a flow of liquid from the first and second liquid holding tanks to the housing;
a waste tank positioned beneath the first and second liquid holding tanks, the waste tank comprising a full liquid sensor;
wherein the housing comprises:
a diffuser plate positioned within the housing and extending from a top of the housing to a base of the housing, the diffuser plate positioned non-perpendicularly to the top of the housing and the base of the housing and separating the housing into a first chamber and a second chamber, a top portion of the first chamber comprising a first distance from the diffuser plate to a front wall and a lower portion of the first chamber comprising a second distance from the diffuser plate to the front wall, the second distance less than the first distance;
an ultrasonic transducer aperture in the base of the housing configured to receive an ultrasonic transducer, the diffuser plate comprising an air aperture straddling the ultrasonic transducer aperture;
a fan positioned on the top of the housing and configured to force air downward into the first chamber, wherein the air is compressed to a first pressure into the lower portion of the first chamber, the compressed air passing through the air aperture of the diffuser plate and over the ultrasonic transducer as it passes to a bottom portion of the second chamber, the air decompressing in the bottom portion to a second pressure less than the first pressure;
at least one discharge tube coupled to the top of the housing above the second chamber, wherein sub-10 micron-sized droplets in the second chamber flow upwardly to the at least one discharge tube, wherein the at least one discharge tube is coupled to a hinged lid on the wheeled cart,
wherein when the hinged lid is in a closed position, the at least one discharge tube is enclosed within the wheeled cart with an exit of the least one discharge tube resting in a basin, wherein excess moisture in the basin is configured to flow to the waste tank via a conduit interposed between the first and second liquid holding tanks; and
an outlet pipe coupled to the waste tank, the outlet pipe comprising an electronic valve;
a controller configured to control an on/off status of the ultrasonic transducer and the fan, and is further configured to control an open/closed status of the at least one electronic valve upon determining the status of:
a. the first and second liquid sensors of the first tank,
b. the first and second liquid sensors of the second tank, and
c. the full liquid sensor of the waste tank; and
a user control panel comprising an on/off switch and a plurality of indicators.
