ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to air freshener dispensers and more particularly pertains to a new liquid air freshener dispensing device for a duct for dispensing liquid freshener into air being heated and moved by a furnace.
2. Description of the Prior Art
The use of air freshener dispensers is known in the prior art. More specifically, air freshener dispensers 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. 4,018,266; U.S. Pat. No. 5,050,798; U.S. Pat. No. 4,574,491; U.S. Pat. No. 4,065,262; U.S. Pat. No. 3,861,052; and U.S. Des. Pat. No. 330,682.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new liquid air freshener dispensing device for a duct. The inventive device includes a container having a top wall, a bottom wall and a peripheral wall extending between the top and bottom walls. A fragrant liquid is located in an interior of the container. An intake conduit extends through the top wall and into the interior of the housing such that a first end of the intake conduit is positioned in the housing and a second end of the intake conduit is located outside of the housing. A pump is in fluid communication with the second end of the intake conduit. The pump is operationally coupled to a power supply of a blower member. An exit conduit has a first end in fluid communication with the pump. The exit conduit extends into a duct such that a second end of the exit conduit is located in an interior space of the duct. The blower member blows air over a heating member and into the heating duct. The pump expels the fragrant fluid into the duct when the blower member is powered.
In these respects, the liquid air freshener dispensing device for a duct 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 dispensing liquid freshener into air being heated and moved by a furnace.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of air freshener dispensers now present in the prior art, the present invention provides a new liquid air freshener dispensing device for a duct construction wherein the same can be utilized for dispensing liquid freshener into air being heated and moved by a furnace.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new liquid air freshener dispensing device for a duct apparatus and method which has many of the advantages of the air freshener dispensers mentioned heretofore and many novel features that result in a new liquid air freshener dispensing device for a duct which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art air freshener dispensers, either alone or in any combination thereof.
To attain this, the present invention generally comprises a container having a top wall, a bottom wall and a peripheral wall extending between the top and bottom walls. A fragrant liquid is located in an interior of the container. An intake conduit extends through the top wall and into the interior of the housing such that a first end of the intake conduit is positioned in the housing and a second end of the intake conduit is located outside of the housing. A pump is in fluid communication with the second end of the intake conduit. The pump is operationally coupled to a power supply of a blower member. An exit conduit has a first end in fluid communication with the pump. The exit conduit extends into a duct such that a second end of the exit conduit is located in an interior space of the duct. The blower member blows air over a heating member and into the heating duct. The pump expels the fragrant fluid into the duct when the blower member is powered.
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 liquid air freshener dispensing device for a duct apparatus and method which has many of the advantages of the air freshener dispensers mentioned heretofore and many novel features that result in a new liquid air freshener dispensing device for a duct which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art air freshener dispensers, either along or in any combination thereof.
It is another object of the present invention to provide a new liquid air freshener dispensing device for a duct which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new liquid air freshener dispensing device for a duct which is of a durable and reliable construction.
An even further object of the present invention is to provide a new liquid air freshener dispensing device for a duct 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 liquid air freshener dispensing device for a duct economically available to the buying public.
Still yet another object of the present invention is to provide a new liquid air freshener dispensing device for a duct 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 liquid air freshener dispensing device for a duct for dispensing liquid freshener into air being heated and moved by a furnace.
Yet another object of the present invention is to provide a new liquid air freshener dispensing device for a duct which includes a container having a top wall, a bottom wall and a periphe
