DETAILED DESCRIPTION OF THE DRAWINGS
With reference now to the drawings, and in particular FIGS. 1 through 5 thereof, the principles and concepts of the toilet ventilation apparatus generally designated by the reference number 10 will be described.
Referring to FIGS. 1 and 2, the seat 20 has a top 25a spaced apart from the bottom 25b and an inner perimeter 21 spaced apart from the outer perimeter 22. The seat further comprises a rear 25c. 
Referring to FIG. 3, the seat 20 further comprises the pair of spaced apart hinges 50 selectively affixing the seat 20 to an existing bowl 15 of an existing toilet 12. The seat 20 is provided in a plurality of sizes and thickness to correctly fit most existing bowls 15 and to retain the use of the existing lids 14.
Referring again to FIG. 2, the quartet of spaced apart stops 23 is disposed on the seat bottom 25b proximal to the outer perimeter 22.
Continuing to refer to FIG. 2 and referring also to FIGS. 4 and 5, the plurality of orifices 24 is disposed within the seat 20 bottom 25b. The orifices 24 ideally number 18 and are disposed adjacent to the inner perimeter 21 for best gas acquisition.
The seat 20 bottom 25b location of the orifices 24 also helps for the seat 20 appear more like a typical existing seat. The interior passage 26 is disposed throughout the seat 20 between the inner perimeter 21 and the outer perimeter 22. A connecting passage 27 connects each orifice 24 to the interior passage 26 so that the interior passage can importantly be located about evenly between the inner perimeter 21 and the outer perimeter 22, thereby importantly assisting in seat 20 structural integrity.
Continuing to refer to FIGS. 4 and 5 and referring also to FIG. 3, the escape tube 28 is connected to the interior passage 26 and passed out the seat 20 rear 25c. The moisture proof seal 29 is disposed around the escape tube 28 at the seat 20 rear 25c to shield against invasion of moisture and dirt at the seat 20 rear 25c. 
Referring again to FIG. 1, the flexible suction hose 32 is connected to the escape tube 28 via the pivoting quick connect fitting 30. The vacuum pump 40 is connected to the discharge hose 34. The switch 44 disposed on the vacuum pump 40 provides selective control of the pump 40. The power cord 42 extends from the vacuum pump 40 and is removably plugged into an existing electrical outlet. The drain collar 35 is ideally sized to fit to an existing drain 16. The drain collar 35 is connected after the existing trap 18 so that gasses are not released back into a toilet room. Gasses are thereby vented to a sewer line. The collar fitting 36 is connected to the drain collar 35. The discharge hose 34 connects the vacuum pump 40 to the collar fitting 36.
The collar fitting 36 importantly provides for quick installation of the apparatus 10 with a minimum of time and tools as the fitting is ideally sized to fit existing 11⁄2 inch drains 16.
Referring to FIGS. 4 and 5, the orifices comprise a diameter 38 of about 1⁄4 inch. The connecting passages 27 further importantly comprise a diameter 38 of about 1⁄4 inch. The interior passage further importantly comprises a diameter 38 of about 1⁄4 inch. The diameters 38 of the passages provide best gas flow velocities to exiting gasses, thereby increasing the effectiveness of the apparatus 10 while negating any use of a high wattage vacuum pump 40. The quick connect fitting 30 provides easy attachment to and detachment from the suction hose 32 by way of the female release collar 31a on the escape tube that is selectively pulled back from the male insert 31b disposed on the suction hose 32. Pulling back on the female release collar 31a releases the male insert 31b for removal and for insertion.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the toilet ventilation apparatus, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the toilet ventilation apparatus.
Directional terms such as “front”, “back”, “in”, “out”, “downward”, “upper”, “lower”, and the like may have been used in the description. These terms are applicable to the embodiments shown and described in conjunction with the drawings. These terms are merely used for the purpose of description in connection with the drawings and do not necessarily apply to the position in which the toilet ventilation apparatus may be used.
Therefore, the foregoing is considered as illustrative only of the principles of the toilet ventilation apparatus. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the toilet ventilation apparatus to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the toilet ventilation apparatus.
