ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electric lighter, and more particularly, to an electric lighter which installs a rechargerable battery therein and if the supply of a charging current stops due to the cut-off of external power, heats a hot wire by the discharging of the rechargerable battery, to be thereby ignited.
2. Discussion of Related Art
Lighters are generally classified into an oil lighter, a gas lighter, an electric lighter, etc. In more detail, the oil lighter is constructed in such a manner that an additive is mixed into a volatile oil and a wick connected to the mixture is thus ignited by means of a lighter stone.
The gas lighter is constructed in such a manner that the gasified gas by the use of a liquefied gas is ignited by means of a lighter stone or an electronic gun which generates a momentary high voltage.
On the other hand, the electric lighter is widely used as a cigar lighter installed in a vehicle, which is constructed in such a manner that a high voltage is applied to a resistant body such as, for example, a filament and a heat source is thus supplied by the operation of the resistant heat generated from the resistant body.
Since the oil lighter and gas lighter are used in the state where the flame is formed upwardly in view of the characteristics of the structure and fuel thereof, however, there occurs a problem that if they are to be used in a downward direction or in an area where the use of firearms is restricted, they can not be freely used.
Therefore, in the area where the direction of the position to be used or the use of firearms is restricted, for example, in the automobile during running, it is convenient to use the electric lighter.
However, since a conventional electric lighter heats the hot wire by the ignition operation and, after completion of the heating for a predetermined time, is used during the heating of the heated hot wire without any supply of power, there still are some problems in that the usable life is short and a heat expansion volume is enlarged to prolong the heating maintaining time of the hot wire, which results in the increment of a preheating time.
Specifically, in case of the cigar lighter used in the automobile, it should be used within the heating maintaining time during the running, such that the limited time of the heating maintaining time becomes an obstacle to the safety running. At this time, instead of using the cigar lighter attached to the vehicle, most of drivers use a general portable lighter. Unfortunately, this may cause an unexpected explosion of the portable gas lighter due to the increment of an internal temperature of the vehicle in summer.
SUMMARY OF THE INVENTION
Accordingly, the present invention is directed to an electric lighter that substantially obviates one or more of the problems due to limitations and disadvantages of the related arts.
An object of the invention is to provide an electric lighter which is capable of continuously supplying power to an ignition part, to be thereby used without any delay, if necessary, and reducing a hot wire volume at a minimum of size, to thereby heat the hot wire without any delay, such that it can extend a usable life, decrease the heat expansion volume of the hot wire to shorten a preheating time, and be freely used in the area where the use of firearms is restricted or in the automobile during running.
According to an aspect of the present invention, there is provided an electric lighter including: a cylindrical body comprised of a DC external power supply to which power is supplied from the outside and a fixed housing coated by a first conductor on the internal surface thereof and having a space portion into which a portable body is inserted; and the portable body comprised of an ignition part in which a resistance heating body such as, for example, a filament is installed, a partition part formed on the bottom portion of the ignition part, an internal electrical power connection means having a circular projection on the external surface thereof and a groove formed on the internal side thereof, into which a tension spring is compressed and expanded in accordance with the engagement with the cylindrical body, the internal electrical power connection means coated with a second conductor on the external surface thereof, a rechargerable battery adapted to be charged by the power supplied through contact points on the both ends thereof and protruded contact points, and a separated housing for supporting the ignition part, the partition part, the internal electrical power connection means and the rechargerable battery, the separated housing and having a hole into which the circular projection is protruded, the separated housing coated with a third conductor on the internal surface thereof and separated into two stages.
According to another aspect of the present invention, there is provided a portable electric lighter including: an ignition part in which a resistance heating body such as, for example, a filament is installed and a switch is provided to be switched by the load generated when an opening part formed on the upper portion of the one side thereof is opened, the ignition part coated by a conductor on the internal surface thereof; a charging part having external power supply terminals formed on the lower portion thereof, for receiving power by the contact with the terminals of an adapter used in charging AC and DC and having a rechargerable battery for discharging through the external power supply terminals, in the case where the switch is contacted with the conductor thereof by the load generated when the opening part is opened downwardly, the charging part coated by a conductor on the internal surface thereof; and a portable case adapted to support the ignition part and the charging part.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
