The present disclosure relates generally to a fire lighter. More particularly, the present disclosure relates to air fire lighter for starting a solid fuel fire.
Since cave dweller days, lighting a fire in a safe, efficient and rapid manner is desired by all who seek a fire for heating and cooking. No longer is rubbing two sticks together or striking a flint to spark a fire considered as anything but a last resort.
Many devices on the market are available to start a solid fuel fire such as a campfire, a charcoal grill, fireplace or chimenea that burn charcoal or wood. Some are simply long matches, cigarette lighters with a long tip or a glowing wire powered by electricity.
While these units may be suitable for the particular purpose employed, or for general use, they would not be as suitable for the purposes of the present disclosure as disclosed hereafter.
In the present disclosure, where a document, act or item of knowledge is referred to or discussed, this reference or discussion is not an admission that the document, act or item of knowledge or any combination thereof was at the priority date, publicly available, known to the public, part of common general knowledge or otherwise constitutes prior art under the applicable statutory provisions; or is known to be relevant to an attempt to solve any problem with which the present disclosure is concerned.
While certain aspects of conventional technologies have been discussed to facilitate the present disclosure, no technical aspects are disclaimed and it is contemplated that the claims may encompass one or more of the conventional technical aspects discussed herein.
An aspect of an example embodiment in the present disclosure is to provide a portable fire lighter. Accordingly, the present disclosure provides a fire lighter device that is battery-operated, lightweight and compact with a swiveling handle that folds in towards a housing for easy portability and storage and further adjusts into a plurality of positions forming a wand, a pistol grip or positions therebetween for optimal placement of the lighter in relation to solid fuel.
Another aspect of an example embodiment in the present disclosure is to provide a convenient fire lighter. Accordingly, the present disclosure provides a fire lighting device that operates without an external power source, useable anywhere without requiring a connection to electrical power.
A further aspect of an example embodiment in the present disclosure is to provide a safe fire lighter for lighting a solid fuel fire that isolates gaseous fuel from an operating electrical fan. Accordingly, the present disclosure provides a device that closes off fuel when the fan is activated once the solid fuel is glowing.
Yet a further aspect of an example embodiment in the present disclosure is to provide a fire lighter with a gaseous fuel for lighting a solid fuel fire. Accordingly, the present disclosure provides a chamber with a conduit coupling a liquid fuel reservoir to a collar distal to the reservoir, the conduit transporting the fuel to the collar where it is ignited into a flame and the flame applied to the solid fuel.
Yet another aspect of an example embodiment in the present disclosure is to provide a fire lighter that blows air for establishing and spreading a fire after initial ignition. Accordingly, the present disclosure provides a fire lighter with a fan in a chamber, the chamber having ducting and a volume that provides optimal airflow to the fire for establishing and spreading the fire after an initial glowing stage through the solid fuel.
The present disclosure describes an air fire lighter having fuel, an igniter and a ducted fan for igniting a solid fuel fire. The fuel in a gaseous state travels through the fire lighter to a collar at a distal end of the fire lighter, and is ignited by the igniter. As the solid fuel begins to glow at the initiation of the fire, the fan is activated, shutting off the vapors from the fuel. The fan blows air through a chamber onto the fire, causing the fire to spread throughout the solid fuel, establishing and spreading the fire. The chamber has a volume and ducting for providing optimal airflow to the fire. The fan is battery-operated. The lighter is lightweight and compact with a swiveling handle that adjusts into a plurality of positions forming a wand, a pistol grip or positions therebetween for optimal placement of the lighter in relation to solid fuel and folds easy portability and storage.
A further example embodiment of the air fire lighter is disclosed, having a pair of barrels, a first barrel for the gaseous fuel and a second barrel housing the axial fan. A canister of flammable gas couples directly to the air fire lighter, eliminating the need to transfer fuel to a reservoir.
The present disclosure addresses at least one of the foregoing disadvantages. However, it is contemplated that the present disclosure may prove useful in addressing other problems and deficiencies in a number of technical areas. Therefore, the claims should not necessarily be construed as limited to addressing any of the particular problems or deficiencies discussed hereinabove. To the accomplishment of the above, this disclosure may be embodied in the form illustrated in the accompanying drawings. Attention is called to the fact, however, that the drawings are illustrative only. Variations are contemplated as being part of the disclosure.
In the drawings, like elements are depicted by like reference numerals. The drawings are briefly described as follows.
The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein. Rather, these example embodiments are provided so that the present disclosure is thorough, complete and fully conveys the scope of the present disclosure to those skilled in the art.

It is understood that when an element is referred hereinabove as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present.
Moreover, any components or materials can be formed from a same, structurally continuous piece or separately fabricated and connected.
It is further understood that, although ordinal terms, such as, “first,” “second,” “third,” are used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, “a first element,” “component,” “region,” “layer” or “section” discussed below could be termed a second element, component, region, layer or section without departing from the teachings herein.
Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, are used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It is understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
Example embodiments are described herein with reference to cross section illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, example embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein, but are to include deviations in shapes that result, for example, from manufacturing. For example, a region illustrated or described as flat may, typically, have rough and/or nonlinear features. Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present claims.
In conclusion, herein is presented an air fire lighter. The disclosure is illustrated by example in the drawing figures, and throughout the written description. It should be understood that numerous variations are possible, while adhering to the inventive concept. Such variations are contemplated as being a part of the present disclosure.
