## Title
Toilet bowl venting apparatus

## Abstract

Apparatus 10 discloses a venting apparatus for a toilet bowl 12 using a gasket 18 that is positioned between a toilet seat 14 and toilet bowl rim 16 forming a gasket-like seal therebetween. The toilet bowl gasket 18 is comprised of a pliable oval-like housing having an interior cavity 20 therein. Located remotely to the venting apparatus is a motorized exhaust fan 22 connected to conduit 24 extending between the toilet seat venting apparatus and discharge vent 26. The exterior walls have a plurality of apertures 28, 30 therein serving to draw air from the toilet bowl 12 and exterior ambient air through the cavity 20 to an aperture having an exteriorly extending nipple 32 with the aforementioned conduit attached thereto whereby activating the pump 22 causes air to be drawn into the cavity 20 and discharged at the point of discharge 26. The exterior ambient air apertures 28 and the toilet bowl interior apertures 30 vary in diameter whereby a larger interior aperture results in a low pressure gradient 38 existing within the bowl interior and a high pressure gradient 40 on the exterior side thereby insuring that the majority of air is drawn from the toilet bowl. A shield 42 is formed over each of the apertures 28, 30 to prevent errant urination from passing into the cavity 20.

## Background
BACKGROUND OF THE INVENTION
