Abstract
An ignition device of an electronic lighter comprises a ceramic seat, electric heating wires, conductive wires, and a circuit board; the ceramic seat having 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 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




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.

1


, electric heating wires


2


, conductive wires

, a circuit board


4


. A pair of through holes


10


are formed in the ceramic seat


1


. The conductive wires

pass through the through holes


10


. The lower ends of the conductive wires


3


are connected to the bottom of the circuit board


4


. The upper ends of the conductive wires


3


are bent with an angle to be connected with at least one electric heating wire


2


. A pair of electric heating wires


2


are illustrated in the Figures. The top surface of the ceramic seat


1


is installed with a hemispherical groove


11


so that the electric heating wires


2


do not contact the groove of the ceramic seat


1


. The joint


41


on the circuit board


4


may be directly connected to a power wire in order to reduce the whole space. The ceramic seat


1


is formed by a secondary seat


12


and a primary seat


15


. The shape of the primary seat


15


is a round cylinder at the upper half and a semi-cylinder at the lower half. The upper half is cut to be formed with a pair of transversal grooves


16


, while the lower half is formed with a pair of half inclined trenches


17


. A pair of conductive wires


3


pass through the inclined trenches


17


. Of course, the top surface of the primary seat


15


is formed with a groove


11


, and an inserting hole


18


is formed in the inner surface thereof. The secondary seat


12


is semi-cylindrical. The inner surface thereof is installed with a pair of half inclined trenches


13


. The half inclined trenches


13


and


17


are formed as the through hole


10


. The inner surface thereof is formed with a post


14


. The post


14


is exactly buckled in the inserting hole


18


so that the inner surface of the lower half of the primary seat


15


contacts the inner surface of the secondary seat


12


. Then, the conductive wires


3


are positioned and the primary seat is adhered to the ceramic seat


1


. Another, the ceramic seat


1


is fixed to the surface of the circuit board

are sightly protruded.

FIG. 4

shows that the present invention is installed on a lighter. The lighter has a housing


5


. A pair of cells


51


serve to supply power to the ignition device


1


. The cells


51


are placed thereinto from a cell cover


52


. The upper end of the housing


5


is installed with a pair of control devices


54


and


55


for power transfer. When one sliding cover


53


is open, the sliding cover


53


will drive an opening to cause a spring


54


to rotate so that one end of the spring is in contact with the conductive piece


55


. While another end


56


of the spring


54


connects with a circuit board


4


. Another end of the cell will be directly connected to the circuit board


4


. Thus, current is conductive to transfer power to the circuit board


4


and then flows through the conductive wires

to generate heat.




In the aforesaid structure, in the present invention, a ceramic seat with a primary seat and a secondary seat is used, which can be manufactured and combined easily. A pair of electric heating wires are connected between two upper ends of the conductive wires, then the two half ceramic seats are combined. Finally, the circuit board is fixed to the housing of an electronic lighter. Since the ceramic seat is installed with a groove, the electric heating wires do not make contact with 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 the 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. Therefore, the present invention has a structure completely different from that of the prior art.




Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
