ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to exhaust systems and more particularly pertains to a new exhaust cleaning device for removing a portion of carbon containing molecules from exhaust.
2. Description of the Prior Art
The use of exhaust systems is known in the prior art. More specifically, exhaust systems 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. No. 5,138,835; U.S. Pat. No. 4,881,959; U.S. Pat. No. 5,272,874; U.S. Pat. No. 5,305,602; U.S. Pat. No. 4,875,335; and U.S. Des. Pat. No. 421,649.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new exhaust cleaning device. The inventive device includes a tubular member which is elongate and has a first end and a second end. The first and second ends are placed in communication with an exhaust system such that gas exhaust flows into the first end and outwardly through the second end. The tubular member has a middle section and two legs extending upwardly from the middle section such that the tubular member generally has a U-shape. A cleaning assembly for cleaning the exhaust includes a plurality of apertures extending through a bottom half of the middle section of the tubular member. A housing is attached to an outer surface of the bottom half of the middle section and covers the apertures such that the apertures extend into the housing. The housing has an opening therein. A container is extendable into the opening. A filter means is removably positioned in the container. A water pump is in communication with a supply tank. A supply line is has a first end fluidly coupled to the water pump and a second end fluidly coupled to the tubular member. The second end is located nearer the first end than middle section. A fluid is located in the supply tank. The fluid comprises water is basic and has a pH greater than 9. The fluid is injected into the tubular member such that the fluid binds to carbon containing molecules in the exhaust and deposits the molecules in the filter.
In these respects, the exhaust cleaning device 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 removing a portion of carbon containing molecules from exhaust.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of exhaust systems now present in the prior art, the present invention provides a new exhaust cleaning device construction wherein the same can be utilized for removing a portion of carbon containing molecules from exhaust.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new exhaust cleaning device apparatus and method which has many of the advantages of the exhaust systems mentioned heretofore and many novel features that result in a new exhaust cleaning device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art exhaust systems, either alone or in any combination thereof.
To attain this, the present invention generally comprises a tubular member which is elongate and has a first end and a second end. The first and second ends are placed in communication with an exhaust system such that gas exhaust flows into the first end and outwardly through the second end. The tubular member has a middle section and two legs extending upwardly from the middle section such that the tubular member generally has a U-shape. A cleaning assembly for cleaning the exhaust includes a plurality of apertures extending through a bottom half of the middle section of the tubular member. A housing is attached to an outer surface of the bottom half of the middle section and covers the apertures such that the apertures extend into the housing. The housing has an opening therein. A container is extendable into the opening. A filter means is removably positioned in the container. A water pump is in communication with a supply tank. A supply line is has a first end fluidly coupled to the water pump and a second end fluidly coupled to the tubular member. The second end is located nearer the first end than middle section. A fluid is located in the supply tank. The fluid comprises water is basic and has a pH greater than 9. The fluid is injected into the tubular member such that the fluid binds to carbon containing molecules in the exhaust and deposits the molecules in the filter.
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 exhaust cleaning device apparatus and method which has many of the advantages of the exhaust systems mentioned heretofore and many novel features that result in a new exhaust cleaning device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art exhaust systems, either alone or in any combination thereof.
It is another object of the present invention to provide a new exhaust cleaning device which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new exhaust cleaning device which is of a durable and reliable construction.
An even further object of the present invention is to provide a new exhaust cleaning device 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 exhaust cleaning device economically available to the buying public.
Still yet another object of the present invention is to provide a new exhaust cleaning device which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of th
