Abstract

An ignition device including a housing, which is formed of an upper shell, a bottom shell, and a partition plate longitudinally connected between the upper shell and the bottom shell; a gas release device mounted within the housing and controlled to release a fuel gas for burning; a sliding control key device mounted on the housing and controlled to drive the gas release device, causing the gas release device to release the fuel gas, and to produce static sparks for burning the fuel gas; and a fan device mounted within an upright endless wall on the partition plate between the upper shell and the bottom shell and controlled by the sliding control key device to draw a flow of air into the housing, permitting the flow of air to be further guided out of the housing for accelerating the burning of the article been burnt by the ignition device.

Claims

1. An ignition device comprising:

a housing, said housing comprising an upper shell, a bottom shell fastened to said upper shell, and a partition plate longitudinally connected between said upper shell and said bottom shell;

a gas release device mounted within said housing controlled to release a fuel gas for burning, said gas release device comprising a fuel gas container having a gas nozzle, a flame nozzle, and a gas tube connected between said flame nozzle and said gas nozzle;

a sliding control key device mounted on said housing and controlled to drive said gas release device, causing said gas release device to release said fuel gas, and to produce static sparks for burning said fuel gas, said sliding control key device comprising a push knob, a sliding key coupled to said push knob and moved to drive said gas release device and having a longitudinal chamber, an actuating rod mounted in said longitudinal chamber, a piezoelectric device mounted in said longitudinal chamber and controlled by said actuating rod to release static sparks through a conductor for burning said fuel gas to make a flame; and

a fan device mounted within an upright endless wall on said partition plate between said upper shell and said bottom shell, said fan device comprising a motor controlled by said sliding control key device and having an output shaft, and a fan blade coupled to said output shaft and driven to draw a flow of air into said housing, permitting said flow of air to be further guided out of said housing for accelerating the burning of the article which is burnt by said flame.

2. The ignition device of claim 1 wherein said upper shell comprises a front projection at one end matched with a respective front projection on said bottom shell, a half-round rear projection at an opposite end matched with a respective half-round rear projection on said bottom shell and connected with the half-round rear projection on said bottom shell to said extension tube, a bottom chamber, which receives said motor, a longitudinal sliding slot, which receives said sliding key, a top slope extended backwardly upwards from said longitudinal sliding slot for placing the thumb, an adjustment hole in front of said longitudinal sliding slot for passing the control lever of an adjustment ring which controls the flow rate of said gas nozzle, a through hole spaced between said longitudinal sliding slot and said adjustment hole through which a fuel gas filling valve which is installed in said fuel gas container projects, and two opposite bottom hooks respectively hooked on respective retaining holes on said partition plate.

3. The ignition device of claim 1 wherein said partition plate comprises a first pair of opposite retaining holes at two opposite sides respectively hooked up with the bottom hooks on said upper shell, a battery chamber to hold a battery set, two contact metal strips fixed to said battery chamber at two opposite ends and respectively connected to the two opposite terminals of said battery set, a plurality of ribs disposed in front of said endless upright wall for guiding said sliding key, two side notches, a safety device mounted between said side notches and moved transversely between the operative position to stop said sliding key and the non-operative position to release from said sliding key for permitting said sliding key to be driven by said push knob, a L-shaped metal spring plate disposed outside said endless upright wall and having a contact spaced from a respective contact on said motor, and a second pair of retaining holes for mounting said bottom shell, one contact metal strip being connected between said metal spring plate and a respective contact of said motor by conductors.

4. The ignition device of claim 2 wherein said partition plate further comprises an endless upright wall connected to said upper shell to hold said motor, an upward stop rod upwardly extended from said endless upright wall, an axle hole within said endless upright wall through which said output shaft of said motor extends outside said partition plate, a channel-like upright support disposed at one side by said endless upright wall to hold said L-shaped metal spring plate, permitting said L-shaped metal spring plate to be forced by said sliding key into contact with the respective contact on said motor in turning on said motor.

5. The ignition device of claim 1 wherein said bottom shell comprises a top chamber to hold said fan blade, an air input port through which air is drawn into said housing by said fan blade, an opening corresponding to said battery chamber and closed by a battery lid, a front projection matched with the front projection of said upper shell, a front upright mounting rod and a rear upright mounting rod respectively fixed to said upper shell by a respective screw, two upright hooks respectively hooked on the second pair of opposite retaining holes on said partition plate, a rear half-round projection matched with the rear half-round projection of said upper shell, two opposite side notches corresponding to the side notches on said partition plate for mounting said safety plate.

6. The ignition device of claim 5 further comprising a socket fastened to the front projections of said upper shell and said bottom shell to hold a fully-clay holder ring, which holds said flame nozzle in place, said socket having air vents for letting outside air in.

7. The ignition device of claim 5 further comprising an extension tube connected to the half-round rear projections of said upper shell and said bottom shell for guiding said flow of said from said fan blade out of said housing.

8. The ignition device of claim 1 wherein said push knob has a bottom groove for coupling to said sliding key;

said sliding key has a rail fitted into said bottom groove of said push knob.

9. The ignition device of claim 8 wherein said said push knob has a rear hole and a spring having one end fastened to said rear hole and an opposite end stopped against an upright stop rod on said partition plate.

10. The ignition device of claim 1 wherein said sliding key has two longitudinal projecting rods respectively inserted into respective holes on said fuel gas container.

11. The ignition device of claim 3 wherein said sliding key has a bottom projection, which stops at said safety plate when said safety plate is moved to the operative position.

12. The ignition device of claim 2 wherein said gas release device further comprises an adjustment ring mounted on said gas nozzle, and a control level extended from said adjustment ring out of the adjustment hole on said upper shell for turning said adjustment ring to regulate the flow rate of said gas nozzle.
