(51) Referring now to FIG. 1A-1B, the present invention features an odor removal system (100) for removing malodors from a toilet (5). In some embodiments, the system (100) may comprise a seat base (110) configured to be placed on a back end (12) of a toilet bowl (10), a toilet seat (140) pivotably connected to the seat base (110), and an air purifying device (150) fluidly coupled to the seat base (110).

(52) In one embodiment, the seat base (110) may comprise a base housing (120) having an air intake (127) disposed on an interior edge (121) of the base housing, and an air outtake (128) disposed on an exterior edge (122) of the base housing and fluidly coupled to the air intake (127). In one embodiment, the base housing (120) can have a hollow interior chamber (125). A tubing (126) may be disposed inside the hollow interior chamber and fluidly connects the air intake (127) to the air outtake (128). In one embodiment, the air intake may be centrally disposed on the interior edge of the base housing. In another embodiment, the air outtake may be disposed on a side or back exterior edge of the base housing. In preferred embodiments, the interior edge (121) of the base housing is adapted to be positioned at or adjacent to an inner toilet bowl rim (14) of the toilet bowl. For example, the interior edge (121) may extend about to about 2 past the inner toilet bowl rim (14). Alternatively, the interior edge (121) may be flushed with the inner toilet bowl rim (14).

(53) In other embodiments, the seat base (110) may also include a toilet seat connector (130) disposed on a top surface (123) of the base housing. In one embodiments, the toilet seat (140) may be pivotably connected to the base housing (120) via the toilet seat connector (130). Referring to FIGS. 2A-2B, in preferred embodiments, the toilet seat (140) has a lip (142) disposed on an inner rim (144) of the toilet seat and projecting outwardly from an underside surface (146) of the toilet seat. As such, when the toilet seat (140) is in a closed position such that the toilet seat (140) is parallel to the base housing (120), the lip (142) is configured to overlap the air intake (127) of the base housing, thus forming a channel (148) between the lip (142) and air intake (127) so as to allow air flow into the air intake (127). Without wishing to limit the invention to a particular mechanism, the toilet seat lip forming the channel with the air intake can prevent air obstruction while also preventing debris from being suctioned into the air intake.

(54) In some embodiment, the seat base (110) may further include a toilet lid connector (135) disposed adjacent to the toilet seat connector (130). As such, the system may further comprise a toilet lid (160) pivotably connected to the base housing (120) via the toilet lid connector (135). As shown in FIG. 1A, the seat base has a platform disposed on a top surface (123) of the base housing. The toilet lid connector (135) and the toilet seat connector (130) may be disposed on the side edges of the platform. Preferably, the toilet lid connector (135) is closer to the back edge of the platform and the toilet seat connector (130) is closer to the front edge of the platform. Thus, when the system is in a closed configuration, the toilet lid covers and overlaps the toilet seat.

(55) In some embodiments, the air purifying device (150) may be fluidly coupled to the air outtake (128) of the base housing. For instance, a conduit (126) or tubing may fluidly connect the air purifying device (150) to the air outtake (128). In some embodiments, the air purifying device (150) may comprise an air filtration component (152), an air drawing component (154) fluid coupled to the air filtration component (152), and a power switch (156) operatively coupled to the air drawing component (154) for turning the air drawing component (154) on and off. The power switch (156) may be a manual switch, such as a proximity switch or an infrared proximity switch.

(56) In some embodiments, the odor removal system (100) may be use in a method to remove malodors from the toilet (5). To implement the method, the toilet seat is disposed in the closed position and the air drawing component (154) is turned on via the power switch (156). The air drawing component (154) suctions the malodors such that the malodors flow into the channel (148) and the air intake (127), exits through the air outtake (128), and is directed into the air filtration component (152). The air filtration component (152) filters the malodors to produce filtered air that exits the air purifying device (150) via air vents (158). In some embodiments, the method may be implemented before using the toilet, during use, after use, or a combination thereof. After a sufficient period of time has passed to ensure that there are little to no lingering malodors, the air drawing component (154) is then turned off via the power switch.

(57) Referring now to FIG. 3, according to another embodiment, the odor removal system (100) for removing malodors from a toilet (5) may comprise a seat base (110) and an air purifying device (150). The seat base (110) may comprise a base housing (120) having a flange (1120) projecting perpendicularly from an interior edge (121) of the base housing, an air intake (127) disposed on an inner side surface (1121) of the flange (1120) at or near a terminating edge (1122) of the flange (1120), and an air outtake (128) disposed on an exterior edge (122) of the base housing and fluidly coupled to the air intake (127).

(58) In some embodiments, the air purifying device (150) may be fluidly coupled to the air outtake (128) of the base housing. For example, a conduit (126) or tubing fluidly connects the air purifying device (150) to the air outtake (128) of the base housing. In one embodiment, the air purifying device (150) may comprise an air filtration component (152), an air drawing component (154) fluid coupled to the air filtration component (152), and a power switch (156) operatively coupled to the air drawing component (154) for turning the air drawing component (154) on and off. In one embodiment, the power switch is a manual switch, such as a proximity switch or an infrared proximity switch.

(59) In preferred embodiments, as shown in FIG. 4, the seat base (110) is adapted to be placed on a toilet bowl (10) such that a bottom surface (124) of the base housing is contacting a top surface (16) of the toilet bowl (10). More preferably, the flange (1120) is positioned to hang downwardly from an inner toilet bowl rim (14) of the toilet bowl so that the inner side surface (1121) and air intake (127) of the flange (1120) faces an interior surface (18) of the toilet bowl. Thus, a channel (148) is formed between the interior surface (18) of the toilet bowl and air intake (127) so as to allow air flow into the air intake (127). Without wishing to limit the invention to a particular mechanism, the flange forming the channel with interior surface (18) of the toilet bowl can prevent air obstruction while also preventing debris from being suctioned into the air intake.

(60) In some embodiments, the odor removal system (100) may be use in a method to remove malodors from the toilet (5). To implement the method, the seat base (110) is placed on the toilet bowl (10) such that a bottom surface (124) of the base housing is contacting the top surface (16) of the toilet bowl (10) and the flange (1120) hangs downwardly from the inner toilet bowl rim (14) so that the inner side surface (1121) and air intake (127) of the flange (1120) faces an interior surface (18) of the toilet bowl. The air drawing component (154) is then turned on via the power switch (156) and suctions the malodours. Preferably, the malodors flow through the channel (148) and into the air intake (127), exit through the air outtake (128), and are directed into the air filtration component (152), which filters the malodors to produce filtered air that exits the air purifying device (150) via air vents (158). The method may be implemented before using the toilet, during use, after use, or a combination thereof. After a sufficient period of time has passed to ensure that there are little to no lingering malodors, the air drawing component (154) is then turned off via the power switch.

(61) In some embodiments, as shown in FIG. 5, the base housing (120) can have an interior chamber (125) that fluidly connects the air intake (127) to the air outtake (128). Referring to FIG. 6A, in one embodiment, the air intake may be an elongated slot that is parallel to the terminal edge (1122) of the flange (1120). The elongated slot can have a J-shaped interior channel that merges with the interior chamber of the base housing. In some embodiments, the elongated slot may be about 0.5-1 cm wide (top to bottom) and about 10-30 cm long (side to side). Referring to FIG. 6B, in another embodiment, the air intake may comprise a plurality of apertures, each aperture fluidly coupled to its own interior channel disposed within the flange. Each interior channel then merges with the interior chamber of the base housing. In some embodiments, the apertures can have an opening surface area of about 1 mm.sup.2-1 cm.sup.2, for example, about 25 mm.sup.2. In other embodiments, the flange can have a width of about 2-5 cm. Preferably, the flange can have a curvature similar to the curvature of the inner toilet bowl rim.

(62) An alternative embodiment of the flange is shown in FIG. 10. In this embodiment, the terminal end of the flange is angled such that the external side surface of the flange extends past the internal side surface of the flange. The air intake may be disposed on the terminal end of flange and faces downwardly. Without wishing to limit the invention to a particular mechanism, the external side surface of the flange extending past the internal side surface of the flange can prevent preventing debris from being suctioned into the air intake while allowing air flow into the air intake

(63) In some embodiments, the air purifying device (150) described herein may be battery-powered or AC/DC powered. In one embodiment, the air filtration component (152) may comprise an activated charcoal filter, a HEPA filter, or an odor absorber air filter or sponge.
