The present invention relates generally to a toilet seat and more specifically to an odor removing toilet seat.
The battle to keep bathrooms and public restrooms smelling clean and fresh is an everlasting one. The saturation of the market with air freshening sprays, deodorizers, and filter systems is strong evidence of this battle. However, no matter the strength of any freshener, they are no-match for the obnoxious odors from human waste during the actual use of a toilet. Room exhaust fans help somewhat in this situation with regards to preventing the odor from leaving the room but do very little to help those in the room or those who enter the room shortly thereafter. Additionally, microscopic particles of fecal matter bacteria can float in the air and can contaminate surfaces and items in the bathroom. Accordingly, there exists a need for a means by which human waste odors and associated bacteria can be removed directly from the toilet bowl and preventing such odors from saturating a bathroom or restroom. The use of the odor removing toilet seat allows for a more pleasing olfactory experience during bathroom use in a manner which is simple and effective.
In view of the foregoing references, the inventor recognized the aforementioned inherent problems and observed that there is a need for an odor removing toilet seat comprises a seat upper surface which enables a user to sit thereon, a seat lower surface and a central opening which directs a plurality of bodily waste from the user into a toilet bowl below and a rear portion of the odor removing toilet seat having a higher profile than a front portion and at least one hinge. The one hinge is located at a rear of the odor removing toilet seat and is capable of hinged attachment to a rim of a toilet bowl and protruding forward. This is done so as to vertically align the central opening of the odor removing toilet seat with the toilet bowl. The odor removing toilet seat also comprises a battery which is housed in a front center section of the odor removing toilet seat.
The odor removing toilet seat also comprises a pump housing which is sized and shaped to house a vacuum pump and a plurality of associated inlet and outlet lines, a first side of the pump housing having a first side filter housing, a second side filter housing which is located at a second side of the pump housing. Each of the first side and second side filter housings houses a scent pack, a filter, and a pre-filter. The odor removing toilet seat also comprises a sensor which is in electrical communication between the battery and the vacuum pump. The sensor is adjacent a frontmost edge of the rear portion of the odor removing toilet seat.
The odor removing toilet seat also comprises a ridge which has a configured geometry to match the upper perimeter interior edge of the rim of the toilet and to create a seal from the interior of the bowl to the environment, a pair of feet providing a standoff of the odor removing toilet seat from the rim of the toilet bowl and the ridge which has a configured geometry to match the upper perimeter interior edge of the rim of the toilet and to create a seal from the interior of the odor removing toilet bowl to the exterior environment and a plurality of vent apertures located along an inner surface of the ridge. The vent apertures are in environmental communication with the pre-filter, the pre-filter is in environmental communication with the filter, which is in environmental communication with the scent pack.
The odor removing toilet seat may be generally planar and may include a plurality of rounded inner and outer edges. The battery may be a lithium ion battery and may be recharged with an induction charging system. The first and the second side filter housings and the pump housing may be accessed by a door for replacement or maintenance.
The pre-filter may provide a way to screen or filter out entrained large particles or liquid if they are drawn through the vent apertures. The sensor may sense the user is sitting on the odor removing toilet seat when the vacuum pump is activated. The sensor may be an infrared sensor. The lid of the odor removing toilet seat may not interfere with the sensor while the vent apertures may be equidistantly spaced.
The vent apertures on the first side of the odor removing toilet seat may be in environmental communication with the pre-filter located in the first side filter housing. The of vent apertures on the second side of the odor removing toilet seat may be in environmental communication with the pre-filter located in the second side filter housing. The environmental communication may be by tubing or may be molded-in passageways. The interior of the odor removing toilet seat between the ridge, the seat upper surface, and the seat lower surface may be hollow. The scent pack may be in environmental communication with, or is an integral part of, an inlet to the vacuum pump.
The inlet may fully reside within the pump housing or traverse between the respective first or second side filter housing and the pump housing. Exiting the vacuum pump may be the outlet, which is in environmental communication with a screen located on a back wall of the rear portion of the odor removing toilet seat and in communication with the room environment the toilet and the odor removing toilet seat reside. The filter may be an activated charcoal filter.

Both the first and second side filter housings 12, 14 and pump housing 13 may be accessed by a door (not shown) for replacement or maintenance. The pre-filter 29 provides a way to screen or filter out entrained large particles or liquid if they happen to be drawn through the vent apertures 31. The filter 28 is preferably an activated charcoal filter and the scent pack 27 is a removable feature that may be commercially produced and replaced when it is spent. The screen 23 can be a mesh or other similar material.
In a preferred method of use, when the battery 20 has a charge to enable proper usage of the device, a user places the seat 10 on the rim of the toilet bowl via the hinges 11 such that the ridge 30 provides a seal to the environment. The user then sits on the seat upper surface 15 and the sensor 21 senses the presence of the user and activates the vacuum pump 25. The vacuum pump 25 induces a vacuum, which draws in untreated air 60 from within the bowl of the toilet and through the plurality of apertures 31. The untreated air 60 passes through the pre-filter 29 and filter 28 and scent pack 27 and is transformed into treated air 61, which enters the inlet 26a. The vacuum pump 25 transfers the treated air 61 to the outlet 26b, which is now designated as forced treated air 62. The forced treated air 62 is then transferred to the room environment through the screen 23.
