[0036] Those skilled in the art will appreciate that although the exterior housing 12 is shown as having three rectangular, vertical sides, the housing may be provided in any shape, and the door may also be provided to have any shape. Further, although the door is depicted as opening outwardly, it is contemplated that the door may also open inwardly.

[0037] The mobile platform exterior housing 12 may include manual handle 18 and four wheels 16 that allow the system 10 to be manually positioned and moved to different desired locations for sanitizing and disinfecting with a dispensing hose and nozzle, in some embodiments.

[0038] Door 12c supports an oxygen tank 14 that is secured to the door 12c by a support bracket 20 that firmly holds the oxygen tank 14 in place, while being suspended and attached to housing 12. An oxygen tank 14 manual on/off flow valve 14a is provided on oxygen tank 14. Another on/off flow valve 22 and oxygen pressure gauges 24 that can measure the pressure in the oxygen tank 14, while valve 22 allows the oxygen tank to be turned on and off when providing oxygen to an ozone generator 44, (FIG. 2), discussed below.

Another status light could show low oxygen O.sub.2. Those skilled in the art will appreciate that although four status lights are shown, the objects, features and advantages of the present invention may be provided and carried out using any number of status lights to indicate any number of notifications to a user.

[0039] Referring now to FIG. 2, the system 10 is shown, with door 12d in the open position. The inside of the exterior housing 12, and the components and equipment that generate the ozone saturated dry mist and dispense the ozone saturated dry mist for sanitation, sterilization, deactivation and/or disinfection are shown.

[0040] A major component of the system 10 is a water storage tank 30 that occupies a volume inside of the exterior housing 12. The water storage tank 30 is substantially a rectangular six-sided cube or rectangular prism that is used to receive and store pure water. Although a rectangular shape for the exterior housing 12 is shown, those skilled in the art will appreciate that the shape of the housing can be anything while still carrying out the objects, features and advantages according to the present invention. The water, vibrated by an ultrasonic oscillator, becomes the ozone saturated dry mist used in the invention. The water storage tank 30 has rigid metal walls that are substantially rectangular, a rectangular floor or base and a rectangular top that has at least two access fittings around ports. Although a rectangular shape of the water storage tank is described above, those skilled in the art will appreciate that the water storage tank may have any shape while still carrying out the advantages, features, and benefits according to the present invention. For example, the water storage tank may be cylindrical in shape. Further, those skilled in the art will appreciate that the present invention may include a plurality of water storage tanks. One access fitting port is for receiving water to be used in the water storage tank and a second access fitting port is for dispensing the ozone saturated dry mist sanitizer from the water storage tank 30, described in detail below. It is preferable that the water used in the water storage tank is purified water, or filtered water, but those skilled in the art will appreciate that any other type of water an also be used, such as, for example, distilled water.

[0041] In FIG. 2, an air blower 42 and its outlet are attached to one of the vertical water storage tank 30 side walls 30e. An ozone generator 44 is attached physically to the inside of exterior vertical wall 12e and has an outlet conduit (not shown) attached to the same vertical water storage tank wall 30e as the air blower 42. Thus, air that is blown into the water storage tank 30 from the same vertical side wall 30e as ozone is being directed into the water storage tank 30 from the same side wall 30e is shown below. The water storage tank 30 may have sensors (not shown in FIG. 2) to determine the maximum and minimum water levels permitted in the water storage tank so that the incoming air from air blower 32 along with the incoming ozone directed into the water storage tank 30 are above the water surface.

[0042] Inside the water storage tank 30 there is an inductive outside float, housing an ultrasonic oscillator used to generate the dry mist that gets mixed by incoming air from air blower 42 along with ozone being generated by ozone generator 44. This operation is discussed below. Near the bottom of the water storage tank 30 is a drain and drain valve 34 that allows the water storage tank 30 to be drained by gravity when necessary to remove any undesired water. FIG. 2 shows, mounted on door 12d on the inside, an electrical control unit 36 and an electrical power unit 38, all of which may include the logic circuits and power necessary for controlling the air blower 42, the ozone generator 44 for generating ozone and operating the dry mist ultrasonic oscillator (that floats inside the water storage tank 30). Electronic operating units 36 and power units 38 also control solenoid valves and the flow rates of the air coming from blower 42 and the dispensing rate of dry mist to achieve the proper proportions of dry mist and ozone to create the ozone saturated dry mist for use in the system 10, discussed below.

[0043] Referring now to FIG. 3, an exploded view of system 10 is shown. The water storage tank 30 is shown elevated, for illustration purposes, above the exterior housing 12. The water storage tank 30 includes an enclosed, six-sided rectangular prism that includes a rigid metal top surface 30a that has two access fittings and ports 30b and 30c. Those skilled in the art will appreciate that although the water storage tank 30 is depicted as a six-sided rectangular prism, it can be provided by any shape such as, for example, a cylindrical storage tank. Access fitting 30b is a port to receive pure water that is deposited into the water storage tank 30 when necessary. Access fitting 30c is a port used to dispense the ozone saturated dry mist sanitizer and/o disinfectant, generated in the water storage tank 30 mixing chamber 30e. Each access fitting port, 30b and 30c, is connected to the lid (not shown in FIG. 3) to a comparably functioning access fitting port, directly above, in exterior housing 12a top panel, shown as access fittings ports 12b and 12d (FIG. 1). The exterior housing access fitting port 12b can be connected by a conduit to the water storage tank 30b to allow the input of water from outside the exterior housing 12 into the water storage tank 30 in order to fill the water storage tank to the correct level with water. Access fitting port 12d, FIG. 1, in the exterior housing pan& 12a, is connected to a conduit (not shown in FIG. 3) attached to water storage tank top panel access fitting port 30c disposed in the top surface 12a of the exterior housing, that connects to a dispensing hose (FIG. 1A) for dispensing the ozone saturated dry mist ozone sanitizer from inside water storage tank 30 blending chamber 30e.

[0044] In FIG. 3, the water storage tank 30 contains inside an ultrasonic oscillator 40 (elevated above for illustration purposes). The ultrasonic oscillator 40 is an ultrasonic transducer that generates ultrasonic frequencies from a piezoelectric crystal using ceramic discs submerged in water in the water storage tank to generate dry mist in the water storage tank blending chamber, 30e above the water surface, The water storage tank 30 includes a water level sensing device 30d that sets the displays maximum height (or depth) of water in the water storage tank 30. The ultrasonic oscillator 40 includes a float 40b, that is doughnut-shaped in some embodiments. The float 40b may be connected to an interior flat pan& that includes a plurality of ultrasonic oscillator (frequency generating) discs that are the transducers that vibrate to generate dry mist in the water while the ceramic discs are submerged below the water, while suspended on float 40a. In some embodiments, applicants have an ultrasonic oscillator with 12 discs mounted on a flat pan& that is connected to a float so that the discs are suspended below the water surface and maintain at least a one-half inch below the water surface at all times to permit the generation of dry mist. The number of ultrasonic piezoelectric oscillator ceramic discs, to generate dry mist, which in one embodiment is 12, can vary widely, dependent on the water storage tank 30 and its function. In this embodiment, the invention 10 is a portable unit for sanitizing and/or disinfecting hard and soft surfaces and airborne particles with an ozone saturated dry mist. The ozone saturated dry mist ultrasonic oscillator 40 has an electrical connection that provides the proper voltage and amperage to each individual oscillator disc 40a that vibrates together and are all connected electrically parallel so the ceramic discs 40a all share the same voltage during operation. The ultrasonic oscillator 40, as a dry mist generator to create the dry mist to dissolve for the ozone to create an ozone saturated dry mist sanitizer and/or disinfectant, is also connected to the system electrical operating system that controls its power, on and off, and its operation at all times.

[0045] Referring to FIGS. 1A and FIG. 4, the method or process of sanitizing, treating, sterilizing and/or disinfecting and/or deactivating hard and soft surfaces and airborne particles in the ambient air to eliminate bacteria and viruses, primarily focuses on creating an ozone saturated dry mist in the water storage tank 30 using the ultrasonic oscillator 47. An air blower 42 directs air, under low pressure, into the water storage tank 30 and downwardly toward the surface of the water therein, above the level of the ozone entering the water storage tank. Ozone generator 44 generates the ozone that is directed into the water storage tank above the surface of the water, below the incoming air flow from the air blower, to mix with the dry mist being generated by ultrasonic oscillator 40 dry mist generator. The purpose of the invention is to generate a desired ratio of dry mist in union with the ozone, to create an ozone saturated dry mist, so that when the sanitizer dispenser dispenses the ozone saturated dry mist under low pressure on a hard or soft surface and airborne particles, the proper ratio is provided for the zone to act to eliminate bacteria and viruses on a hard or soft surface and airborne particles and at the same time the ozone saturated dry mist evaporates from the surface quickly, so that a sanitized and/or disinfected surface does not get wet or damp or leave any deleterious residue. Applicants have determined that 80 to 90, and up to 150 parts per million of ozone in the dry mist is very effective as a sanitizer and/or disinfectant for bacteria and viruses on hard and soft surfaces without wetting the surfaces, not leaving a deleterious residue harmful to humans.

[0046] Referring now to FIG. 4, the invention system 10 is shown, with a side elevational view of exterior housing 12 cutaway on one side, so that the inside of the water storage tank 30 (viewed in cross-section) is represented schematically in operation, partially filled with water 30f. The water storage tank 30 lower volume 30f, contains water 60. Above the water surface in the upper volume blending chamber 30e of water storage tank 30 is an ozone saturated dry mist 62 that has been generated by the ultrasonic oscillator 40 attached to float 40a on the surface of water 60. Ultrasonic oscillator discs 40a (FIG. 3) act as transducer frequency generators to generate dry mist 62 in the water storage tank 30, housed in the ultrasonic oscillator 40, and submerged to remain suspended below the water 60 surface. Also shown is the air blower 42 attached to the side wall of water storage tank 30 so that the air directed into the water storage tank upper area (above the water surface) containing the dry mist is directed downwardly by a diverter 42a, forcing the incoming air toward the water surface. Also mounted through the side wall of water storage tank 30 is the ozone generator 44 that also is positioned below the air blower 42 so that incoming ozone from ozone generator 44 is near the surface of the water 60 so that ozone interacts directly with the dry mist coming from the water surface and the downward air directed from air blower 42, creating ozone saturated dry mist 62 in the upper volume of water storage tank 30.

[0047] FIG. 4 shows conduits 46 and 48 each attached between the exterior housing panel 12a and the access fitting ports 12b and 12d and the water storage tank 30 access fitting ports 30b and 30c. Conduit 48 is used to supply water internally from the exterior housing 12 through access fitting port 12d into water storage tank access port 34, for filling the water storage tank 30 when necessary. Conduit 46 is used to disperse the dry mist and ozone mixture sanitizer in blending chamber 30e to create an ozone saturated dry mist from water storage tank 30 through water storage tank access fitting 30c and exterior housing access fitting 12b. connected to dispersing hose 52. (FIG. 1A), A nozzle 50 (FIG. 1A) may be attached on the end of the hose 52. The hose 52 and nozzle 50 direct the ozone saturated dry mist on hard and soft surfaces and airborne particles to be sanitized and/or disinfected. Therefore the system 10 is operated by providing power to air blower 42, ozone generator 44, and the ultrasonic oscillator 40 which has discs suspended underwater, approximately half an inch, that are vibrated to create the dry mist in the blending chamber 30e in the upper portion of water storage tank to create an ozone saturated dry mist 30. Also shown in FIG. 4 is a drain valve 34 which is connected outside of the exterior housing for emptying the water storage tank 30 of water.

[0048] The treating, dispensing, sanitizing, sterilizing, deactivating and/or disinfecting method and system can create a treating, sanitizing, sterilizing and/or disinfecting ozone saturated dry mist to sanitize and/or disinfect surfaces and airborne particles by creating a dispersed sanitizing evaporating dry mist vapor, super-saturated with ozone. The sanitizing ozone saturated dry mist is created using a pressure differential dispersant method. The ozone saturated dry mist will sanitize and or disinfect hard surfaces and airborne particles and penetrate porous surfaces and ambient air to sanitize and/or disinfect. It kills bacteria and viruses, and other pathogens on hard and soft surfaces and in ambient air.

[0049] In some embodiments, sanitizing apparatus utilizing the components, described in FIG. 1B-FIG. 3, can be mounted on a mobile platform, that includes wheels and a frame network with a handle, for manually moving and positioning an entire sanitation apparatus various locations, which allow the delivery system to be positioned manually, thereby allowing a technician to thoroughly sanitize and/or disinfect an area with a mobile platform and the ability to manually position the output of the delivery system for sanitizing various surfaces.
