     TECHNICAL FIELD 
     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. 
     BACKGROUND 
     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. 
     BRIEF SUMMARY 
     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. 
     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.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       FIG. 1  illustrates an air fire lighter  10  for starting a solid fuel fire. The air fire lighter initiates a fire by heating solid fuel with a lighter flame until combustion begins and a glow point forms in the fuel. The air fire lighter spreads the fire by blowing air on the glow point, distributing the heat and combustible vapors released by the solid fuel at a glow point stage to adjacent solid fuel until a persistent combustion stage is established, forming a vibrant flame that is further spread by the blowing air. The solid fuel is, for example, but not limited to, wood, charcoal, peat, coal, biomass pellets and other similar combustibles that burn producing heat and light. The solid fuel is burnt, for example, but not limited to, in an open campfire, a stove, a grill, a fireplace, a chimenea, a fire pit and a smoker. 
     The air fire lighter  10  has a housing  12  and the housing has a barrel  14  with a distal end  14 D and a proximal end  14 P. The barrel has an internal chamber described hereinbelow. The housing has a plurality of air ducts  18  admitting air into the chamber from the ambient air surrounding the lighter. The housing has a grip  20  coupled to the barrel at the proximal end  14 P. The lighter flame is produced at the distal end of the barrel  14 D.  FIG. 3  illustrates the fire lighter in cross-section from a side view perspective of the housing  12 . Inside the housing is a fuel module. The fuel module has a liquid fuel in a reservoir  30 , the reservoir in the grip  20 . The fuel is vaporized in the reservoir. The fuel module has a burner collar  40  at the distal end  14 D of the barrel. A conduit  42  couples the reservoir  30  and the collar  40  operative for transporting the gaseous fuel from the reservoir to the collar, the conduit  42  operative for mixing air with the gaseous fuel through an opening before the fuel presents at the collar  40 . 
     The lighter has an igniter module having an igniter  50  at the distal end  14 D of the barrel adjacent to the collar  40 . In one embodiment, the igniter is a piezo igniter. In a further embodiment, the igniter is an automatic igniter that electrically generates a spark. The igniter module has a switching means. In the illustrated example embodiment shown in  FIG. 3 , the igniter module has a trigger  22  on the grip  20  for initiating the lighter flame. The trigger when activated, is operative for opening the reservoir  30  to the conduit  42 , allowing the gaseous fuel to flow to the collar  40 , the trigger operative for generating a spark from the igniter  50 , the spark igniting the gaseous fuel at the collar  40  producing the lighter flame operative for starting the solid fuel fire to a glow point stage. The igniter is coupled to the collar  40  by a conducting wire  52 , the electrical discharge of the igniter  50  traveling along the wire to the collar  40  producing the spark. Piezo ignition and automatic ignition by electrically generated spark are well known to those of ordinary skills and more detailed discussion is beyond the scope of this disclosure. 
     The trigger  22  has a safety switch  24  for compliance with safety standards. The trigger has a continuous button for operating the flame continuously locking the trigger in an operating position. The button is not shown. 
     In another example embodiment, which is not shown, a sliding switch slides in one direction for opening the reservoir and generating the spark as explained hereinabove and slides in an opposite direction operative for activating a fan as explained hereinbelow. 
     A battery-operated fan  60  is inside the chamber  16 , the fan activated after the fire is at the glow point stage. In the figure illustrating the example embodiment, the fan is an axial fan. Activating the fan  60  closes off the liquid reservoir  30  to the conduit  42 . The fan is operative for establishing and spreading the fire throughout the solid fuel as described hereinabove, the fan blowing air through the chamber  16  and out the distal end  14 D of the barrel onto the solid fuel fire, the air stimulating the fire to the persistent combustion stage as explained hereinabove. 
     The chamber  16  inside the barrel  14  has a length around 30 centimeters and an internal diameter of around 3.5 centimeters. In the illustrated example embodiment, the axis  62  of the fan is centered in the chamber and parallel to the barrel  14 , creating a pressure chamber but other configurations are possible within the inventive concept, the fan creating the pressure chamber from any angle. The fan has a plurality of air flow flanges that are not shown. Airflow is significantly affected by the design of the fan and housing, and the length and diameter of the barrel. Appropriate ducting of the fan assists in the best flow of air for delivering the most effective volume and airflow. 
     In one example embodiment, the ducts  18  are behind the fan  60  at the proximal end of the barrel. In another example embodiment, the ducts are in the chamber downstream to the fan.  FIG. 1  shows an approximation of the duct location on the barrel  14  in the example embodiment where the ducts are upstream to the fan. 
     Referring to  FIG. 2 , the proximal end of the barrel and the grip  20  is shown. The proximal end of the barrel has the plurality of ducts  18  upstream of the fan. 
     Referring again to  FIG. 3 , the fan  60  is activated by a switch, the switch operative for turning the fan on and simultaneously closing off the liquid reservoir  30  to the conduit  42 . As explained hereinabove, the switch can also toggle the igniter module. 
     The lighter  10  has a plurality of rechargeable batteries  70  coupled to the fan  60  operative for powering the fan. The lighter does not require any other power source, such as AC current so that the lighter is easily portable. The batteries are in a chamber  72  in the housing, however, the placement of the batteries within the housing is not a limitation. In one embodiment, the batteries supply power for the automatic igniter that electrically produces the ignition spark. 
     In one example embodiment, an LED (light emitting diode) flashlight  74  operative for guiding the distal end of the barrel during fire starting is coupled to the housing adjacent to the distal end of the barrel. In a further example embodiment, the second chamber  72  has a distal end  72 D with the LED flashlight  74  operative for guiding the distal end  14 D of the barrel during fire lighting, the LED flashlight selectively actuated by a switch which is not shown. The batteries  70  are coupled to the flashlight operative for powering the flashlight  74 . 
     In a further example embodiment, which is not shown, a bottle opener is coupled to the housing, the bottle opener operative for opening bottles and hanging the lighter on hook for storage. 
     In one example embodiment, the reservoir is selectively refillable through a valve on the grip  20 . The fuel is, for example, but not limited to, butane, but other flammable liquids such a mixture of low molecular weight hydrocarbons and alcohols typically used in charcoal lighter fluid are suitable for an example embodiment of the lighter. 
       FIG. 5A  shows one example embodiment of the lighter  10  wherein the grip  20  is hingedly attached to the proximal end  14 P of the barrel, the grip swiveling around a hinge  26  to a position parallel to the barrel  14  operative for compact storage. In  FIG. 5B , the grip swivels around the hinge to a plurality of positions operative for accurately pointing the distal end  14 D of the barrel  14  at the solid fuel, the barrel addressing the fuel from a plurality of angles. The grip forms a plurality of positions, forming a wand, a pistol grip or positions therebetween for optimal placement of the lighter when addressing the solid fuel. 
     A method of using an air fire lighter to start a solid fuel fire is illustrated in  FIG. 4 . A plurality of solid fuel pieces  100  are arranged, the pieces of solid fuel in contact with each other. 
     A flame  80  is triggered to ignite a fire  90  by pulling a trigger  22  on the air fire lighter  10 . As shown in  FIG. 3 , the trigger  22  is operative for opening the fuel reservoir  30  to a conduit  42 , allowing the fuel to flow to the collar  40 , the trigger operative for generating a spark from the igniter  50 , the spark igniting the gaseous fuel at the collar producing the flame operative for starting the solid fuel fire to a glowing stage. 
     Referring back to  FIG. 4 , the flame  80  of the lighter is pointed at the solid fuel pieces  100  applying the flame directly to the solid fuel, continuously engaging the trigger  22 . 
     Referring back to  FIG. 3 , when the fire is at the glow point stage, the fan  60  is activated inside the chamber  16  in the fire lighter, activating the fan simultaneously closes off the liquid reservoir  30  to the conduit  42 , the fan operative for establishing and spreading the fire throughout the solid fuel, the fan  60  blowing air through the chamber  16  and onto the solid fuel fire, the air stimulating the fire to a combustion stage. 
     Referring again to  FIG. 4 , the lighter flame  80  is applied directly to the solid fuel  100  for 20 seconds to 60 seconds before activating the fan. The fan blows air through the chamber and onto the solid fuel for around two minutes on a single spot  102 . In one example embodiment, the fire is being prepared for cooking and the fan selectively blows air for an additional five minutes on the fire in the burning stage operative for spreading the fire  90  throughout the pieces of solid fuel  100  to quickly bring the fire up to a cooking temperature. 
     In another example embodiment, the step of triggering a flame  80  by pulling a trigger on the air fire lighter  10  is preceded by the step of releasing a safety switch on the trigger  22 . 
     In a further example embodiment, the step of applying the flame  80  directly to the solid fuel  100  for around 20 seconds is followed by the step of selectively engaging a continuous button (which is not shown in the drawing) on the trigger  22  to apply the flame  80  directly to the solid fuel locking the trigger into an engaged position. 
     A method of manufacturing an air fire lighter is shown in  FIG. 3 . The fuel module having a liquid fuel reservoir  30  is coupled to the housing  12  having the barrel  14  with the distal end  14 D, the proximal end  14 P and the grip  20  hingedly coupled to the barrel  14  at the proximal end  14 P, the reservoir operative for storing liquid fuel. The fuel module having a burner collar  40  is further coupled to the housing  12 , the collar  40  at the distal end  14 D of the barrel. The conduit  42  within the housing  12  operative for transporting the fuel from the reservoir  30  to the collar  40 . 
     The igniter module is coupled to the housing  12  and the fuel module. The igniter module has an igniter  50  at the distal end  14 D of the barrel adjacent to the collar  40 , the igniter module has a trigger  22  on the grip  20 , the trigger operative for opening the reservoir  30  to the conduit  42 , the trigger operative for generating a spark from the igniter  50 . 
     The fan  60  is coupled to the housing  12 , the fan having a switch and the shaft  62 , the switch operative for activating the fan and closing off the liquid reservoir to the conduit. In one example embodiment, the fan  60  is within the chamber  16 , the shaft  62  of the fan axially parallel to the barrel  14 , the fan  60  operative for blowing air through the chamber  16  and out the barrel  14 . 
     Coupling the fan  60  to the housing  12  includes operationally coupling a plurality of batteries  70  within the housing  12  to the fan  60 . 
     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&#39;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.
