ABSTRACT:
BACKGROUND OF THE INVENTION
1) Field of the Invention
The subject matter of this invention relates to applying of a small quantity of a deodorizing liquid within a toilet bowl during a single usage of the toilet bowl when being utilized for the discharge of solid and liquid waste.
2) Description of the Prior Art
A toilet comprising a ceramic bowl which is mounted on a floor is in exceedingly common use within most civilized countries. The toilet is to function to dispose of human solid and liquid waste into a sewage system. Toilets are mounted within homes, businesses, recreational vehicles and boats. It is common to mount a ring member known as a seat about the opening into the toilet bowl. The seat is pivotly mounted to the toilet bowl so as to be movable from a lower position in contact with the toilet bowl to an upper position located substantially ninety degrees relative to the toilet bowl.
When a human discharges solid waste there is created noxious odors. It is generally preferable to eliminate these noxious odors as rapidly as possible. One common way to eliminate these odors is by utilizing of an exhaust fan in conjunction with the room in which the toilet is mounted with the purpose of the exhaust fan to remove and discharge the noxious odors into the ambient. Another way that noxious odors are eliminated is by the application of an odor destroying liquid within the toilet bowl.
In the past, there have been designed numerous different types of devices that are to work in conjunction with the toilet bowl that apply a quantity of odor destroying liquid within the toilet bowl during occupancy of the seat. However, in the past these toilet bowl deodorizing systems have had certain disadvantages which have resulted in their non-utilization. The primary disadvantage is that these systems are large in size and therefore, from an appearance point of view, make for an unattractive addition to the structure of the toilet. Another disadvantage is that the systems are difficult to clean not providing for easy disassembly and reassembly for purposes of cleaning. A further disadvantage is that the systems do not necessarily dispense a precise quantity of deodorizing liquid with sometimes dispensing a larger amount of liquid and other times dispensing a smaller and ineffective amount of deodorizing liquid. It would be desirable to design a system that dispensed a precise quantity of liquid which was the correct quantity required.
SUMMARY OF THE INVENTION
The structure of the present invention relates to a toilet deodorizer in the form of a pump housing which is to be mounted between the toilet seat and the toilet bowl. The pump housing actually comprises a piston and cylinder arrangement with there being formed within the pump housing a pump chamber. The piston of the pump housing is biased continuously by a spring toward an expanded position. The pump housing includes an inlet valve and an outlet valve. The inlet valve is to connect to a liquid storage reservoir. The outlet valve is to include an outlet orifice that directs the liquid toward the interior of the toilet bowl. The pump housing is to be removably mounted on a deflector plate with this deflector plate to include a deflecting surface to which the stream of liquid from the outlet valve is to be directed and then dispersed into a fanned series of droplets within the interior of the toilet bowl. Sitting on the seat will cause the disbursement of a precise quantity of the liquid to within the interior of the toilet bowl. Removing of one's body from the toilet seat will cause the toilet seat to be moved to a canted position which will result in a new quantity of liquid being extracted from the storage reservoir and confined within the pump chamber making available a further quantity of liquid for the next usage.
One of the objectives of the present invention is to construct a toilet deodorizing apparatus which can be easily and quickly mounted in conjunction with the toilet seat of a conventional toilet by even of the most unskilled individual and which is simple in construction, strong, durable, compact, of light weight and which can be manufactured at low cost.
Another objective of the present invention is to construct a toilet deodorizing apparatus which provides for the ejecting of a precise quantity of deodorizing liquid within the toilet bowl each and every time of dispensing.
The primary objective of the present invention is to provide a new and unique toilet deodorizing apparatus for mounting on the toilet seat of a conventional toilet which is responsive to use of the toilet to automatically release a precise quantity of deodorizing liquid during use of the toilet.
