DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring in more detail to the drawings, FIGS. 1 and 2 show an exemplary embodiment of a cleaning apparatus 10 that is used to clean simulated hair articles. The cleaning apparatus 10 sterilizes, disinfects, sanitizes, and deodorizes a simulated hair article 12, such as a wig, without the need of water, shampoo, soap, and other cleaning solutions, which commonly require substantial restyling of the simulated hair article after being washed therewith. It also reduces or eliminates odors and microorganisms such as bacteria, viruses, molds, fungi, and the like. The cleaning apparatus 10 is a piece of equipment that is portable and convenient for at-home use, and requires a reduced amount of time for effective cleaning, in some cases 5-10 minutes. As used herein, the term “simulated hair article” includes hair articles made with natural hair, synthetic hair, or a combination of both. In different embodiments, the cleaning apparatus 10 includes a housing 14, an ozone generator 16, an ultraviolet (UV) light source 18, and a gas recirculation structure 20.
The housing 14 encloses and seals the simulated hair article 12 while the simulated hair article is being cleaned. Referring to FIGS. 1 and 2, the housing 14 has a chamber 22, a compartment 24, a panel 26, and a pedestal 28 carried by the panel. The chamber 22 isolates the simulated hair article 12 from the environment outside of the housing 14. The chamber 22 is defined by a cylindrical wall 30, a ceiling or top 32, a door 34, and the panel 26. The door 34 is hinged at one side, preferably locks or latches at the other side when closed, and has a window 35 for viewing the simulated hair article when the door is closed. The door 34 can also have a seal (not shown) around its periphery for sealing the opening when the door is closed.
The compartment 24 houses the ozone generator 16 and the gas recirculation structure 20. The panel 26 extends across the housing 14 and separates the chamber 22 and the compartment 24. The panel 26 has a first opening 36 for connection with the gas recirculation structure 20, and has a second opening 38 also for connection with the gas recirculation structure. The pedestal 28 is carried by the panel 26 and supports the simulated hair article 12. The pedestal 28 has a wire-frame 40 that permits gas to pass therethrough and to the simulated hair article 12 so that gas contacts the simulated hair article on all sides. The pedestal 28 is removable from the housing 14.
In other embodiments, the housing 14 can have different arrangements and configurations, and can have more, less, and/or different components than shown and described. To cite but a few examples, an air freshener could be provided in the housing 14 to emit a scent or odor neutralizer, the pedestal 28 need not be provided and another way of supporting the simulated hair article 12 could be used, the housing could have a rectangular shape, and the door 34 could be located in the ceiling 32.
The ozone generator 16 converts oxygen in the air into ozone gas (O3) and supplies the ozone gas to the chamber 22, where the ozone gas undergoes an oxidation reaction that helps clean the simulated hair article 12. The ozone generator 16 can come in various types including, but not limited to, a corona discharge type, a cold plasma type, and an ultraviolet type. Taking the corona discharge type as an example, the ozone generator 16 produces about 300 mg of ozone gas per hour at about 3.5 cubic feet of gas per minute. In other embodiments, the ozone generator 16 can produce up to about 1000 mg of ozone gas per hour. Referring to FIG. 1, the ozone generator 16 includes an electric switch 42 that turns it ON/OFF, an inlet 44 for receiving gas, and an outlet 46 for discharging ozone gas. The switch 42 could optionally provide a timer that turns the ozone generator ON for a predetermined amount of time, such as 5-10 minutes, and then turns the ozone generator OFF. The ozone generator 16 is located within the compartment 24. Though not shown, a fan, blower, pump, and/or other means of forced circulation could be integrated in the ozone generator 16, or could be provided as a separate component; in these cases, the component draws gas into the ozone generator, expels gas out of the ozone generator, or both. In other embodiments, the inlet 44 could communicate with an exterior of the housing 14 through a conduit, and the ozone generator 16 could be located outside of the compartment 24 and mounted on the housing exterior, to name but a few examples.
The UV light source 18 emits ultraviolet light inside of the chamber 22 to help clean the simulated hair article 12. The emitted ultraviolet light includes light in the UVC range (280-100 nm), and includes wavelengths of about 185 nm, and/or 254-265 nm. Wavelengths of about 185 nm can convert atmospheric oxygen (O2) into ozone gas. Referring to FIG. 1, the UV light source 18 is supported by the housing 14 and located on the ceiling 32 to direct ultraviolet light toward a top of the simulated hair article 12. The switch 42 also turns the UV light source 18 ON/OFF, though a separate switch can be provided exclusively for the UV light source. In other embodiments, the UV light source 18 could be positioned at other locations in the chamber 22 such as on the cylindrical wall 30 to direct ultraviolet light toward a side of the simulated hair article 12, and the UV light source need not be provided at all where the ozone generator 16 alone would clean and sanitize the simulated hair article, to name but a few examples.
The gas recirculation structure 20 circulates gas through the cleaning apparatus 10 from the chamber 22, into the ozone generator 16, and back to the chamber with ozone therewith. In some cases, the circulation increases the concentration of ozone gas in the chamber 22 by taking oxygen that may not have been initially converted or has reverted back to oxygen, and converting it into ozone gas. Still referring to FIG. 1, the gas recirculation structure 20 includes a first conduit 48 extending from the outlet 46 to the first opening 36, and includes a second conduit 50 extending from the second opening 38 to the inlet 44. The first conduit 48 carries gas with ozone therein exiting the ozone generator 16 to the chamber 22, and the second conduit 50 carries gas from the chamber 22 to enter the ozone generator. In other embodiments, the gas recirculation structure 20 can have different arrangements and configurations, and can have more, less, and/or different components than shown and described. For example, the second conduit 50 need not be provided and instead gas could simply flow through the second opening 38 and into the inlet 44, or simply flow through around the panel 26 whereby the panel is not sealed air-tight around its periphery. Indeed, the gas recirculation structure 20 need not be provided at all whereby the ozone generator 16 could draw-in gas from the housing exterior through one or more slots cut into the housing 14, for example. In this case, only the first conduit 48 would be provided and the inlet 44 would draw gas through the slots and into the ozone generator 16.
In some embodiments, a desiccant 52 is provided in the cleaning apparatus 10 to remove water and/or moisture from gas passing therethrough. The desiccant 52 can include various substances that absorb water and/or moisture such as silica gel and calcium chloride, for example. Referring to FIG. 1, the desiccant 52 is located at the inlet 44 of the ozone generator 16. The desiccant could also be located inside of the second conduit 50. Taking water and/or moisture out of the gas entering the ozone generator 16 increases the ozone conversion efficiency of the ozone generator.
In use, the cleaning apparatus 10 preferably uses a combination of ozone gas and ultraviolet light to clean the simulated hair article 12. The simulated hair article 12 is placed on the pedestal 28 and the door 34 is closed to isolate the chamber 22 from the outside environment. Once closed, gas trapped inside of the chamber 22 is subject to circulation through the gas recirculation structure 20. The switch 42 activates the ozone generator 16, the UV light source 18, or a combination of both. For example, in different cleaning cycles, the ozone generator 16 produces ozone gas for a set period of time, then the UV light source 18 emits ultraviolet light for another set period of time, or both occur simultaneously. Likewise, the gas recirculation structure 20 circulates gas through the cleaning apparatus 10 for a set period of time, which is less than the total time for the cleaning cycle, which is equal to the total time, or which is greater than the total time. In the latter case, the gas recirculation structure 20 circulates gas through the ozone generator 16 after the ozone generator ceases producing ozone gas. The ozone generator 16 is turned OFF for a sufficient period of time for ozone gas to revert back to oxygen.
While the forms of the invention herein disclosed constitute presently preferred embodiments, many others are possible. It is not intended herein to mention all the possible equivalent forms or ramifications of the invention. It is understood that the terms used herein are merely descriptive, rather than limiting, and that various changes may be made without departing from the spirit or scope of the invention.
