ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to ventilated litter boxes and more particularly pertains to a new ventilated cat litter box for ventilating cat litter and simultaneously keeping the surrounding area litter free.
2. Description of the Prior Art
The use of ventilated litter boxes is known in the prior art. More specifically, ventilated litter boxes heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. Nos. 5,655,478; 5,134,972; U.S. Pat. No. Des. 331,649; U.S. Pat. Nos. 5,044,325; 5,511,513; and U.S. Pat. No. Des. 350,422.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new ventilated cat litter box. The inventive device includes a box, which is generally rectangular in shape. The box has a top portion, a bottom portion, a middle portion, a first wall, a second wall, a third wall, and a fourth wall. A screen covers the bottom portion of the box and is parallel to the bottom portion. A container, rectangular in shape, is located within the box upon the screen. An arched doorway is located in the first wall. A rectangular cavity is located in the top portion of the box. An electric fan is mounted in the inside of the box and is adjacent to the cavity. An actuating means is operationally coupled to the electric fan. A power source is operatively coupled to the actuating means. A ventilation port is attached to the cavity whereby the port extends upwardly away from the box. An exhaust tube has a first end and a second end. The first end is removably connected to the ventilation port.
In these respects, the ventilated cat litter box according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of ventilating cat litter and simultaneously keeping the surrounding area litter free.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of ventilated litter boxes now present in the prior art, the present invention provides a new ventilated cat litter box construction wherein the same can be utilized for ventilating cat litter and simultaneously keeping the surrounding area litter free.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new ventilated cat litter box apparatus and method which has many of the advantages of the ventilated litter boxes mentioned heretofore and many novel features that result in a new ventilated cat litter box which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art ventilated litter boxes, either alone or in any combination thereof.
To attain this, the present invention generally comprises a box, which is generally rectangular in shape. The box has a top portion, a bottom portion, a middle portion, a first wall, a second wall, a third wall, and a fourth wall. A screen covers the bottom portion of the box and is parallel to the bottom portion. A container, rectangular in shape, is located within the box upon the screen. An arched doorway is located in the first wall. A rectangular cavity is located in the top portion of the box. An electric fan is mounted in the inside of the box and is adjacent to the cavity. An actuating means is operationally coupled to the electric fan. A power source is operatively coupled to the actuating means. A ventilation port is attached to the cavity whereby the port extends upwardly away from the box. An exhaust tube has a first end and a second end. The first end is removably connected to the ventilation port.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new ventilated cat litter box apparatus and method which has many of the advantages of the ventilated litter boxes mentioned heretofore and many novel features that result in a new ventilated cat litter box which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art ventilated litter boxes, either alone or in any combination thereof.
It is another object of the present invention to provide a new ventilated cat litter box which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new ventilated cat litter box which is of a durable and reliable construction.
An even further object of the present invention is to provide a new ventilated cat litter box which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such ventilated cat litter box economically available to the buying public.
Still yet another object of the present invention is to provide a new ventilated cat litter box which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Still another object of the present invention is to provide a new ventilated cat litter box for ventilating cat litter and simultaneously keeping the surrounding area litter free. When the cat steps upon the screen, the litter on its feet from the litter container falls through the screen and into a tray. The litter is thus not carried out of the box.
Yet another object of the present invention is to provide a new ventilated cat litter box which includes a box, which is generally rectangular in shape. The box has a top portion, a bottom portion, a middle portion, a first wall, a second wall, a third wall, and a fourth wall. A screen covers the bottom portion of the box and is parallel to the bottom portion. A container, rectangular in shape, is located within the bo
