The present disclosure relates to refillable gas lighters, and more particularly to a multipurpose, refillable gas lighter used to ignite a gas stove or BBQ grill.
A refillable gas lighter is a portable device that is commonly used at homes for igniting stoves and other variety of combustion materials like barbecue, fireworks etc. Many of the lighters are very useful and common in the present market. It uses a physical phenomenon called piezo-electric effect to generate an electric spark which ignites the combustible gas from the stove burner. The phenomenon of piezo-electric charge is the electric charge that accumulates in some materials in response to high pressure. An electric spark is usually generated once per turn of the knob or press of the button.
Several methods have been developed in the art; one such method describes a utility lighter for barbecue purpose having a resistance unit designed to resist the depressing force applied on the trigger. However, as the depressing force is resisted by the resistance unit, it requires an adult to apply more force to the trigger to ignite the barbecue lighter which in turn damages the components inside the lighter.
Another method discloses a utility lighter having an ignition-resistant mechanism. The ignition-resistant function is performed by a cam mechanism. Even though the structure of cam mechanism provides an optimum amount of safety, it is very difficult for young and old people to operate. Moreover, this type of lighter has a complex construction that increases the maintenance cost.
Yet another gas lighter with safety button allows the user to regulate the outflow of gas to generate a flame. However, while keep pressing on the button, the user may feel tired and the thumb may be easily hurt by the flame. Besides, once the button is released, the flame will immediately go out.
There is thus a need for a wireless, refillable gas lighter to ignite the gas stove or a barbecue grill. This refillable gas lighter would work with the principle of wireless electronics. The present embodiment would use a conductive plate instead of enameled wire as an electrical conductor. Such a refillable gas lighter uses a reverse wireless electronic power supply with a compact structure and is weightless. Further, such a refillable gas lighter would have a plurality of conductors in fixed shape which would make it easy to assemble with automated assembly. Also this refillable gas lighter would have an innovative structure. Present embodiment overcomes the prior art shortcomings in this area and accomplishes these and other critical objectives.
To minimize the limitations found in the prior art, and to minimize other limitations that will be apparent upon the reading of the specification, the preferred embodiment of the present invention provides a multipurpose, refillable gas , lighter for providing a flame for a gas stove or a barbecue grill. The refillable gas lighter has the capability for refilling the gas lighter with multiple times of its usage. The structural design is different from traditional barbecue lighters, is a portable lighter with compact structure, and is light in weight.
The refillable gas lighter comprises a front case, a rear case, a barrel, and a barrel sleeve. A housing is formed by joining a rear case with a rear case neck and a front case with a front case neck. A barrel slides over and interlocks with the front case neck and the rear case neck, and has a flame opening at one end to ignite. A barrel sleeve then slides over the barrel to securably hold the barrel, the rear case neck, and the front case neck in their joined position. The barrel sleeve is cylindrical in shape and is configured to fit the barrel and the portion of the housing joined with the barrel or from which the barrel extends. Inside the rear case, a pusher is connected with a plurality of conducting strips that acts as an electrical conductor. When the pusher is pressed down to the gas tank, inside the gas tank piezo-electric energy is generated, where positive charge is formed in the first conducting strip and passes through the second conducting strip to the spark spring. The pusher is connected with a plurality of conducting strips positioned on the gas tank being connected with a bridge plate. The copper wire connected from the bridge plate carries the energized negative charge through the conductive hose extends to the tip of the barrel where the spark spring is attached. The conductive hose being configured to transfer igniting gas from the gas tank, a flame opening having a spark spring for ignition. The first conducting strip and the second conducting strip, both act as an electrical conductor in this refillable gas lighter which is connected to the spark spring. The spark spring functions as a means for conducting the charges and initiates ignition utilizing a reverse wireless electronic power supply.
A first objective of the present invention is to provide a refillable gas lighter that can easily refill the gas and reuse multiple times.
A second objective of the present invention is to provide a refillable gas lighter that is a portable refillable gas lighter, compact in design and light in weight.
Another objective of the present invention is to provide a refillable gas lighter that utilizes a reverse wireless electronic power supply.
These and other advantages and features of the present invention are described with specificity so as to make the present invention understandable to one of ordinary skill in the art.
