  • Patent number: 5806104
    Abstract: A bathroom deodorizing device for use with a conventional toilet bowl includes a housing having an inlet located between the rear of the toilet seat and the toilet bowl. The inlet captures offensive air which is drawn into the housing by a fan and into a deodorizing chamber. The chamber is in fluid communication with a first and second chamber. The first chamber contains a liquid deodorizer and the second may also contain a liquid deodorant and/or a liquid which is used to impart a desired fragrance into the air before it exits the device. As the air is bubbled into the liquid deodorizer contained in the first deodorizing chamber, the air is cleansed, purified and deodorized and enters the second chamber for a second process and is then released into the surrounding environment. The device includes a pressure activated switch to turn the device on.
