Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present apparatus relates to a rechargeable electronic element lighter, and, in particular, to a heat coil and USB connector fully contained within a single housing, that includes a number of safety improvements and features that assist and provide convenience to the user.
Many lighter devices are in popular use, with means to light a cigarette using electric or gas. It is preferred that a lighter be constructed in a matter that can easily transported in a users pocket. The most commonly used lighter contains a means to create a spark and ignite flammable liquid that stored in close proximity to the flame to allow for a flow of flammable liquid to the spark to create a flame. The flame can be used to ignite the desired object.
A conventional lighter as described above has many disadvantages that are not found in an electric lighter. The flammable liquid is dangerous, particularly to children. The flame is not controlled and can burn the user. The portion of the conventional lighter surrounding the flame conducts heat and can burn the user. Oftentimes the user will have to wait for the lighter to cool down after a failed attempt to light an object. The switch that releases fuel can be inadvertently depressed in a pocket and the fuel may escape. Conventional lighters may include a cap to minimize this problem, however a cap can break off, heat up, or get lost. The fuel is difficult to replace and fumes can escape in the fuel replacement process. The fuel also makes manufacturing a conventional lighter more difficult, dangerous and expensive.
It is therefore desirable to provide a portable USB rechargeable electronic lighter device contained in a protective sliding housing that eliminates the need for flammable fuel.

SUMMARY OF THE INVENTION

In one embodiment, the invention is a system for providing an USB rechargeable electronic element lighter comprising:
