ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an ignition device of an electronic lighter, and especially to a lighting structure ignited by electric power.
BACKGROUND OF THE INVENTION
The electric ignition devices in the prior art have power source of cells for providing power to heat generating elements. In general, the heating generating element is electric heating wires. The electric power from the power source is transferred to the electric heating wires for being converted as thermal power. If the electric heating wires are hidden in a ceramic seat, the heat efficiency will be reduced. Thus, heat dissipation of the electric heating wires are large and rapidly, and longer time is required to ignite the lighting device. Therefore, there is an eager demand for a novel ignition device of an electronic lighter which can improve the defects in the prior art.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide an ignition device of an electronic lighter, in which since the ceramic seat is installed with a groove at the top thereof, the electric heating wires do not contact the ceramic seat, and thus, heat dissipation of the electric heating wires is retained so that a higher temperature is retained. A groove is formed at the top of the ceramic seat, and therefore, it is avoided that the ash from combusting objects will not seal the electric heating wires. Moreover, the present invention occupies a small space and a circuit board is used so as to be installed easily. The circuit board can be easily connected to a power source. A preferred use is provided.
In order to achieve the aforesaid object, the present invention provides an ignition device of an electronic lighter comprising a ceramic seat, electric heating wires, conductive wires, and a circuit board; the ceramic seat has a pair of through holes. The conductive wires pass through the through holes. A lower end of each conductive wire is connected to a bottom of a circuit board. An upper end of each conductive wire is bent to be connected to the electric heating wires. A top of the ceramic seat is formed with a hemispherical groove so that the electric heating wires do not contact the ceramic seat. Thus, it is avoided that ash seals the groove, and thus, the joint of the circuit board is directly connected to wires of the power source. Therefore, the present invention only occupies a small space. The ceramic seat is formed by combining a primary seat and a secondary seat. description when reading in conjunction with the appended drawing.
