CA 2347273
An air ventilation system is provided for removing obnoxious odour air directly from a toilet bowl. The system includes a portal vent formed at the rear underside of the toilet seat. A lateral tube is mounted to the hinge brackets for pivotally mounted the toilet seat to the toilet bowl. The lateral tube has an air inlet opening which is aligned with the portal vent when the toilet seat is at the down position to form an air flow channel. The portal vent and the air inlet opening are offset with one another when the toilet seat is at the up position thus closing the air flow channel to prevent water from overflow or splash to enter into the system. The air flow channel is coupled to a fan for drawing the odour air to the outdoor. A rubber gasket is mounted at the underside of the toilet seat to provide a perfect air seal between the seat and the toilet bowl.
