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 14D and a proximal end 14P. 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 14P. The lighter flame is produced at the distal end of the barrel 14D. 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 14D 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 14D 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 14D 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.

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 72D with the LED flashlight 74 operative for guiding the distal end 14D 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 14P 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 14D 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.

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.
