This invention is directed to an assembly for the filtration and other processing of air and aerosolized fluid issuing from the interior of a toilet bowl.
The odor of human waste released by people into a toilet bowl can enter the general surrounding area and remain suspended during toilet use and for periods of time post toilet use. This can be unpleasant to the present toilet user, to others located in the nearby environment, or to others that enter the area later to use the same toilet.
Air purifiers and air filters are widely used in interior spaces such as homes and offices to minimize the amount of dust, allergens, and micro-organisms that are present in the air. These systems typically include a fan for circulating air and a mechanical filter disposed in an air path to filter or purify air flowing there through. Larger fans, air purifiers and/or air filters tend to be more effective due to the large volume of air they can remove, filter and/or purify at a given time. However, larger units of this type are usually obtrusive and take up a considerable amount of space in the home or office. Further, these larger systems may require more electricity and are often loud due to the size of the fans included in the system.
Although fans, air purifiers and air filters may provide a solution to combating the presence of contaminants such as dust, allergens and micro-organisms, they may lack the means to effectively remove the odors from the air. Individuals are well aware of the offensive odors that may be released from flatulence, feces, or urine. These odors can be disruptive and unpleasant to individuals located in the vicinity of such odors. When unpleasant odors are present in the air, individuals usually commonly use air freshener sprays, plug in air fresheners or the like, to “cover-up” the unpleasant odor with a more pleasant scent. However, this tactic merely masks the presence of the unpleasant odor and does nothing to actually remove the odor.
Additionally, the use of air fresheners or sprays presents an unfortunate problem because an individual must first come in contact with the unpleasant odor before these devices can be used to mask the scent. Furthermore, while the scent of air fresheners, sprays, etc. may provide a more pleasant odor, as compared to odors released from flatulence, feces or urine, some individuals May not enjoy still not enjoy or even be able to tolerate such fragrances.
Accordingly, there is a need for an air filter and/or odor processing assembly and/or system operative to withdraw, filter and otherwise treat or process odors, specifically including those emanating from flatulence, defecation and/or urination, directly from a toilet bowl airspace. Treatment of such odors thereby eliminate or significantly reduce the release thereof into the surrounding airspace. Such processing and/or treatment of such odors may include passing air or aerosolized fluid containing such odors across a filter assembly operatively structured to absorb the odors. In addition, a proposed assembly and/or system of the type referred to may also include a filter assembly capable of removing aerosolized particles contained in a “toilet plume”.
Moreover, the treatment or processing of fluid removed from the interior of a toilet bowl May also include sterilizing capabilities operative to remove germs, bacteria, etc. prior to reaching the air or space surrounding the toilet. In addition, modification of certain structural and operative features may serve to enhance the versatility of an improved odor elimination assembly and/or system, thereby enabling its use in both domestic and commercial environments. Finally, a proposed and improved toilet odor processing assembly and or system which overcomes known disadvantages of the type set forth above, should be designed to be inexpensive, easily serviceable and convenient enough to change install and maintain.
The present invention is directed to an electrically powered, portable air filtration and sterilization assembly, when in use is operatively disposed immediately adjacent to a toilet. As such, it is usable and/or attachable to a majority of existing 2-tank toilet or commercial vacuum flow toilet designs and requires no replacement of the toilet, seat or other mechanical modification of the toilet structure itself. As explained in greater detail hereinafter, the assembly comprises a plurality of interactive, operative components including a housing, a filter assembly disposed in the housing, a fan assembly and an activating switch or member.
In more specific terms, the portable filter assembly of the present invention includes a housing operatively disposable immediately adjacent to the toilet bowl and including a housing inlet and a housing outlet. In use and when operatively disposed, the inlet is positioned in direct fluid communication with an interior of the toilet bowl. To facilitate such direct fluid communication, the inlet comprises a substantially “snout” like structure having an elongated configuration extending outwardly from a remainder of the housing and preferably, but not necessarily, located at an outer or upper end of the housing. The elongated yet relatively small transverse dimension or “thickness” of the snout-like inlet is dimensioned to be disposed above the outer rim of the toilet bowl contiguous to the toilet bowl opening and beneath a toilet seat, when the seat is disposed in a closed relation resting on the toilet bowl rim. The outer end of the inlet includes an inlet port which at least partially defines the aforementioned direct fluid communication with the interior of the toilet bowl.
The portable filter assembly of the present invention further includes a filter assembly disposed within the housing in direct fluid communication and downstream of the inlet. In addition, a fan assembly is operatively associated with a self-contained electrical power source 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 of the present invention includes an activating switch or like structure which when manually or otherwise engaged will serve to operatively interconnect the power source to the fan assembly causing an at least partially continuous but more practically intermittent operation, as explained hereinafter.
Therefore, activation of the fan assembly creates and directs a predetermined path of fluid flow or “fluid flow” through the housing. More specifically, the fluid flow is directed successively through and from the inlet, through the filter assembly, located in communication with the inlet but downstream thereof, and therefrom to an exterior of the housing through the aforementioned housing outlet.
Additional structural features of one or more embodiments of the portable filter assembly of the present invention include the housing comprising a first housing section or base and a second housing section. The first and second housing sections are removably attached to one another in a fluid sealing connection. As should be apparent, the fluid sealing connection between the first and second housing sections facilitates a stabilized or more defined fluid flow of air collected from the interior of the toilet bowl and passing into the interior of the housing through the inlet. Absent the fluid sealing connection between the first and second sections of the housing, leakage or intake of air from an exterior of the housing could possibly enter the housing and pass into the fluid flow. In turn, this may result in a less efficient processing of air collected through the inlet from the interior of the toilet bowl.
Further structural and operative features of the present invention include the aforementioned filter assembly capable of being removed and replaced from its position on or within the removable second housing section. This facilitates access to the filter assembly for removal, repair or replacement thereof thereby allowing repetitive use of the housing by a replacement of the filter assembly when required. Additional details of the filter assembly include a multi-segmented construction structured to remove odors, as well as aerosolized waste and pathogens from the fluid flow passing into the housing through the inlet, which originates from the “air” within the interior of the toilet bowl. More specifically, the multi-segmented construction of the filter assembly comprises a carbon-based filter segment and also may comprise an HEPA filter segment.
For purposes of structural convenience and operability the aforementioned inlet is also connected to and may define and integral portion of the second section of the housing, such that the inlet is removable with the remainder of the second section as it is detached from its fluid sealing connection with the first section of the housing.
Yet additional structural features of the first and second housing sections being removably connected in a fluid sealing connection includes the ability to establish a variably spaced disposition between the first and second housing sections while concurrently maintaining the fluid sealing connection. As set forth herein, and operative disposition of the housing may include it being disposed immediately adjacent to the toilet bowl concurrently to the inlet disposed between the outer rim of the toilet bowl and the under portion of the toilet seat when closed. It is of course recognized that toilet bowls may come in various dimensions and configurations, including having different heights relative to the supporting floor or other supporting surface. Therefore, the variably spaced disposition of the second section of the housing relative to the first section of the housing allows the establishment of a variable height of the housing. Therefore, when the housing is supported on a common supporting surface or floor of the toilet bowl, the height of the housing may be adjusted or varied to facilitate the proper positioning of the snout-like inlet in the intended area between the toilet seat and the surrounding rim of the toilet bowl. As intended, such intended positioning of the inlet facilitates direct fluid communication thereof with the interior of the toilet bowl. In turn, the passage of the odorized and/or partially polluted air from the interior of the toilet bowl, resulting from toilet usage, will pass into the housing through the inlet and be directed with the aforementioned fluid flow through the housing to the outlet thereof.
In one or more embodiments of the portable filtering assembly of the present invention, the aforementioned activating switch 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 may be connected directly on or to the housing in a readily accessible location to a user and be hardwired to operatively connect and disconnect the aforementioned power source to the fan assembly. 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 may be remotely located a spaced distance from the housing, yet still in a readily accessible location. In either of these two structurally modified embodiments, the pressing or otherwise activating of the activating switch, while the fan is turned off, will serve to turn the fan on for a given period of time, thereby causing the fan assembly to establish the aforementioned fluid flow through the housing. A subsequent pressing or otherwise activation of the activating switch, while the fan assembly is operating, will result in a stopping or shut off of the fan assembly, such as when a user of the toilet is finished and sufficient fluid flow through the housing 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 May have incorporated therein a motion detector/sensor structure, 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.
The versatility of the portable filtering assembly of the present invention is further demonstrated by the inclusion of an overflow discharge structure or assembly incorporated within the housing. As a result, the housing and the entirety of the assembly itself is substantially protected against significant damage when the toilet bowl overflows, as is not uncommon, particularly in a domestic environment. In more specific terms, overflow of the toilet bowl may result in toilet water, as versus air, passing into and through the inlet and into the interior of the housing. During such relatively abnormal conditions, the water will be allowed to pass into and through the inlet and possibly downstream through the filter assembly to a diversion structure or path. In addition, a discharge port will be mounted on or connected to the housing in fluid communication with the diversion path or structure for the overflow liquid water. Therefore, the water will be directed downstream of the filter assembly to the discharge port, via the diversion path or structure, and there from through the discharge port to an exterior of the housing.
Moreover, in order to prevent or significantly restrict inadvertent leakage of air into the interior of the housing, thereby possibly, at least partially corrupting the aforementioned fluid flow of air from the interior of the toilet bowl, a valve structure is disposed in flow restricting relation to the discharge port. The valve structure may include, but not be limited to, a check valve is disposed in direct fluid restrict in relation to the discharge port. Such valve structure and/or check valve will allow the exiting of the overflow water from the housing, through the discharge port but prevent or significantly restrict the entrance of air from an exterior of the housing and outside of the toilet bowl from entering into the interior thereof and into the intended fluid flow, as set forth above.
These and other objects, features and advantages of the present invention will become clearer when the drawings as well as the detailed description are taken into consideration.
For a fuller understanding of the nature of the present invention, reference should be had to the following detailed description taken in connection with the accompanying drawings in which:
Like reference numerals refer to like parts throughout the several views of the drawings.
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.
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
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
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.
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
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
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″.
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.
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
More specifically, as represented in
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
In one or more embodiments of the portable filtering assembly 200, the aforementioned activating switch 34 (see
With primary reference to
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.
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.
