DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0028] The invention now will be described more fully hereinafter with reference to the accompanying drawings in which illustrative embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0029] The portable filter assembly of the present invention is generally represented as 200 throughout the Figures and includes a housing generally indicated as 10 which, when in use, is operatively disposable immediately adjacent to the toilet bowl 100 as represented in at least FIG. 1. While the structure and operative components associated with the toilet bowl 100 may vary, for purposes of clarity, FIG. 1 represents the toilet bowl 100 including an upper and outer rim 100 disposed in substantially surrounding relation to the interior of the toilet bowl 100. In addition, a toilet seat 106 is represented in a closed position such that it overlies and is supported by the rim 100 in spaced relation thereto by a bumper or spacer 107.

[0030] The housing 10 includes a first section or base 12 and a second section 14 which may be removably attached to one another by a fluid sealing connection 13 as represented in FIG. 3 as discussed in greater detail hereinafter. Further, the housing 10 includes a housing inlet 16 and a housing outlet 18. In use and when the housing 10 is operatively disposed, the inlet 16 is positioned in direct fluid communication with an interior of the toilet bowl. Again, with primary reference to FIG. 1, to facilitate direct fluid communication with the interior of the toilet bowl 100, the inlet 16 comprises a substantially snout like structure having an elongated configuration extending outwardly from a remainder of the housing 10 and preferably, but not necessarily, located at an outer or upper end of the housing 10 as represented throughout the Figures. The elongated yet relatively small transverse dimension or thickness of the snout-like inlet 16 is dimensioned to be disposed above the outer rim 100 of the toilet bowl 100 which surrounds the toilet bowl opening and interior (not shown for purposes of clarity) and beneath a toilet seat 106, when the seat 106 is disposed in a closed relation resting on the toilet bowl rim 100, via spacer or bumper 107. The outer end of the inlet 16 includes an inlet port 16 which at least partially defines the aforementioned direct fluid communication 111 with the interior of the toilet bowl 100.

[0031] The portable filter assembly 200 a filter assembly 20 disposed within the housing 10 in direct fluid communication and downstream of the inlet 16. In addition, a fan assembly 28 is operatively associated with a self-contained electrical power source 30 specifically including, but not limited to at least one battery and/or a rechargeable battery (AA, AAA or 232 style battery). Also, one embodiment of the portable filtering assembly 200 includes an activating switch, member or like structure 34 which when manually or otherwise engaged will serve to operatively interconnect the power source 30 to the fan assembly 28 causing an at least partially continuous but more practically in an on-off intermittent operation, as explained hereinafter.

[0032] Therefore, activation of the fan assembly 28 creates and directs a predetermined path of fluid flow or fluid flow schematically represented by directional arrows 50 through the housing 10. More specifically, the fluid flow 50 is directed successively through and from the inlet 16, through the filter assembly 20, located in communication with the inlet 16 and downstream thereof, and therefrom to an exterior of the housing 10 through the aforementioned housing outlet 18, as that 50 in FIG. 4.

[0033] As set forth herein, additional structural features of one or more embodiments of the portable filter assembly 200 include the housing 10 comprising the first housing section or base 12 and the second housing section 14. As also indicated, the first and second housing sections 12 and 14 are removably attached to one another in a fluid sealing connection, as at 13 in FIG. 3. The fluid sealing connection 13 between the first and second housing sections 12 and 14 facilitates a stabilized or more defined fluid flow of air 50 collected from the interior of the toilet bowl 100 and passing into the interior of the housing 10 through the inlet 16. Absent this fluid sealing connection 13, leakage or intake of air from an exterior of the housing 10, other than from the interior of the toilet bowl 100, could possibly enter the housing 10 and pass into the fluid flow 50. In turn, such interior leakage may result in a less efficient processing of air collected through the inlet 16 from the interior of the toilet bowl 100.

[0034] Further structural and operative features of the present invention include the aforementioned filter assembly 20 capable of being removed and replaced from its position on or within the removable second housing section 14. This facilitates access to the filter assembly 20 for removal, repair or replacement thereof thereby allowing repetitive use of the housing 10 by a replacement of the filter assembly 20 when required. Additional details of the filter assembly 20 include a multi-segmented construction structured to remove odors, as well as aerosolized waste and pathogens from the fluid flow 50 passing into the housing 10 through the inlet 16, which originates from the air within the interior of the toilet bowl 100. More specifically, the multi-segmented construction of the filter assembly 20 comprises a carbon-based filter segment 20 and also may comprise an HEPA filter segment 20.

[0035] For purposes of structural convenience and operability the aforementioned inlet 16 is also connected to and may define and integral portion of the second section 14 of the housing 10, such that the inlet 16 is movable with the remainder of the second section 14 as it is detached from its fluid sealing connection 13 with the first section 12 of the housing 10.

[0036] Yet additional structural features of the first and second housing sections 12 and 14 being removably connected in a fluid sealing connection 13 includes the ability to establish a variably spaced disposition between the first section 12 and the second section 14 while concurrently maintaining the aforementioned fluid sealing connection 13. As set forth herein and represented in FIG. 1, and operative disposition of the housing 10 may include it being disposed immediately adjacent to the toilet bowl 100 concurrently to the inlet 16 disposed between the outer rim 100 of the toilet bowl 100 and the under portion of the toilet seat 106 when closed. It is of course recognized that toilet bowls may come in various dimensions and configurations, including having different heights relative to a supporting floor or other supporting surface 300. Therefore, the variably spaced disposition of the second section 14 of the housing 100 relative to the first section 12 of the housing 10 allows the establishment of a variable height of the housing 10.

[0037] More specifically, as represented in FIG. 3 the second section 14 is represented as being completely removed from the first section 12. However, the fluid sealing connection 13, including an exterior surface 13 thereof, is cooperatively dimensioned, configured and structured to be inserted within the interior of the second section 14 through the open and 14. Such insertion may include a sliding engagement with the exterior surface 13 with the interior surface of the second section 14 contiguous or adjacent to the open and 14. Accordingly, the aforementioned fluid sealing connection 13 will be maintained as long as the exterior surface 13 is disposed within the interior of the second section 14 and in sealing and possibly sliding engagement with the interior surface of second section 14.

[0038] Therefore, when the housing 10 is supported on a common supporting surface or floor 300 of the toilet bowl 100, the height of the housing 10 may be adjusted or varied, at least partially due to the inlet 16 movable with the second section 14, to facilitate the proper positioning of the snout-like inlet 16 in the intended area between the toilet seat 106 and the surrounding rim 100 of the toilet bowl 100. As intended, such intended positioning of the inlet 16 facilitates direct fluid communication 111 with the interior of the toilet bowl 100. In turn, the passage of the odorized and/or partially polluted air 111 (see FIG. 1) from the interior of the toilet bowl 100, resulting from toilet usage, will pass into the housing 10 through the inlet 16 and be directed with and along the aforementioned fluid flow 50 through the housing 10 to the outlet thereof 18, where it exits through outlet 18.

[0039] In one or more embodiments of the portable filtering assembly 200, the aforementioned activating switch 34 (see FIG. 4) may be in the form of a button or other structure capable of manual manipulation. Further, in at least one embodiment the activating switch or button 34 may be connected directly on or to the housing 10 in a readily accessible location to a user and be hardwired to operatively connect and disconnect the aforementioned power source 30 to the fan assembly 28. In contrast, one embodiment of the present invention may include the activating switch or member being operative wirelessly such as by RF transmission, Bluetooth, etc. Therefore, in this wireless embodiment the activating switch 34 may be remotely located a spaced distance from the housing 10, yet still be in a readily accessible location. In either of these two structurally modified embodiments, the pressing or otherwise activating of the activating switch 34, while the fan assembly 28 is turned off, will serve to turn the fan assembly 28 on for a given period of time, thereby causing the fan assembly 28 to establish the aforementioned fluid flow 50 through the housing 10. A subsequent pressing or otherwise activation of the activating switch 34, while the fan assembly 28 is operating, will result in a stopping or shut off of the fan assembly 28, such as when a user of the toilet is finished and sufficient fluid flow 50 through the housing 10 has been established to remove odors, aerosolized waste, pathogens, etc. From the air within the interior of the toilet bowl. As a further structural and operative variation, the activating switch or member 34 may have a motion detector/sensor structure incorporated therein and be operative to eliminate the need for manual pressing or contact, but responsive to the movement of a hand, etc. over and in observable relation to the motion detector/sensor.

[0040] With primary reference to FIGS. 4 and 5, the versatility of the portable filtering assembly 200 is further demonstrated by the inclusion of an overflow discharge structure or assembly, generally indicated at 60, incorporated within the housing 10. As a result, the housing 10 and at least a majority of the portable filtering assembly 200 is substantially protected against significant damage when the toilet bowl 100 overflows. In more specific terms, overflow of the toilet bowl 100 may result in toilet water, schematically represented by arrows 52, passing into and through the inlet 16 and into the interior of the housing 10 as represented in FIG. 4. During such relatively abnormal conditions, the water flow 52 will be allowed to pass into and through the inlet 16 and possibly downstream through the filter assembly 20 to a diversion structure or path, generally indicated as 62. In addition, a discharge port 64 will be mounted on or connected to the housing 10 in fluid communication with the diversion path or structure 62 for the overflow liquid water 52. Therefore, the overflow water 52 will be directed downstream of the filter assembly 20 to the discharge port 64, via the diversion path or structure 62, and therefrom through the discharge port 64 to an exterior of the housing 10.

[0041] Moreover, in order to prevent or significantly restrict inadvertent leakage of air into the interior of the housing 10, thereby possibly, at least partially corrupting the aforementioned fluid flow of air 50 from the interior of the toilet bowl 100, a valve structure 66 is disposed in flow restricting relation to the discharge port 64. The valve structure 66 may include, but not be limited to, a check valve disposed in direct fluid restricting in relation to the discharge port 64. Such valve structure 64 and/or check valve will allow the exiting of the overflow water 52 from the interior of the housing 10, through the discharge port 64, but prevent or significantly restrict the entrance of air from an exterior of the housing 10, which originates outside of the toilet bowl 100 from entering into the interior of the housing 10 and into the intended fluid flow 50, as set forth above.

[0042] Since many modifications, variations and changes in detail can be made to the described preferred embodiment of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
