ABSTRACT:
A urinal or toilet ventilation system for removing unpleasant odors from the vicinity of the urinal or toilet, both during usage and for a short period of time following usage. The ventilation system has a series of flexible water ducts extending throughout the device and leading to the outside. Additionally, the device has a series of air ducts extending throughout the device and attaching to a motor which in turns pushes the air through another series of ducts leading to the outside. In a further embodiment the urinal or toilet has a sensor to detect the presence of a user for actuating the motor and begins the air extraction system. Upon the user leaving the vicinity of the urinal or toilet, the sensor has a built in delay, and continues to extract any unpleasant odors for a short duration.
