  • Toilet ventilating device
    Patent number: 4590629
    Abstract: A toilet ventilating device with an air pump having an inlet and an outlet. An odor outlet fitting is adapted to communicate with the toilet bowl and the inlet of the air pump. An odor outlet fitting is adapted to communicate between water in the water reservoir of the toilet (typically the water tank), and the air pump outlet. This fitting preferably includes a gas diffuser. Air is withdrawn from the toilet bowl and discharged into the water reservoir through the outlet fitting, such that water in the water reservoir will filter the odorous gases.
