Toilet ventilation system

USPTO Application #: 20080040842
Title: Toilet ventilation system
Abstract: The toilet ventilation system includes at least one toilet seat having an interior air channel disposed through the entire circumference of the seat and a plurality of apertures disposed through the bottom surface communicating with the interior channel. A vacuum pump is connected to the channel by tubing. A plurality of microswitches are attached to the bottom of the toilet seat, including a standby switch that turns the pump on when the seat is lowered onto the bowl, a pressure switch that activates the pump when a person is seated on the toilet, and a water switch that shuts the pump off in the event of a toilet overflow. The pump features microcontroller operation, has an activated charcoal filter for removing odors from air pumped away from the mouth of the toilet bowl, and is powered either by a wall transformer with built-in GFCI protection or by rechargeable batteries.
