Ignition device for electronic lighter with heating wire ceramic mount having hemispherical groove

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.

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

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
 With reference to FIGS. 1 to 4, the ignition device of an electronic
 lighter according to the present invention is illustrated. The ignition
 device of an electronic lighter includes a ceramic seat 1, electric
 heating wires 2, conductive wires 3, a circuit board 4. A pair of through
 holes 10 are formed in the ceramic seat 1. The conductive wires 3 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 4 and the upper ends of the conductive wires 3 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 3 to cause the
 electric heating wires 2 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.
