Description

Technical Field

[0001] This invention relates to the field of ignition device technology, specifically to a novel plasma pulse lighter with single-needle angle ignition. Background Technology

[0002] Currently, conventional ignition devices on the market are mainly divided into two categories: gas igniters and electric arc igniters. Gas igniters rely on an external gas supply, which leads to drawbacks such as gas leaks and inconvenience in carrying them. Furthermore, their ignition efficiency is significantly affected by gas purity and ambient temperature. Electric arc igniters often employ a simple voltage boosting structure, resulting in low boosting efficiency and unstable output voltage, making them prone to ignition failure and insufficient arc intensity. They also lack a robust safety protection mechanism, leading to frequent safety risks such as lithium battery overcharging and over-discharging, overheating and burnout of circuit components, and accidental electric shock. In addition, existing electric arc igniters have low circuit integration, numerous components, and a large size, making them difficult to adapt to portable use requirements. They also cannot achieve precise adjustment of ignition intensity, failing to meet the usage requirements of different ignition scenarios. Overall, they suffer from poor safety performance, low integration, and insufficient practicality. Therefore, a novel plasma pulse lighter with a single-needle angle ignition is proposed. Summary of the Invention

[0003] To address the problems of traditional plasma lighters, such as scattered multi-needle flame emission, poor ignition accuracy, inadequate anti-accidental touch performance of the switch, imperfect safety protection, low circuit integration, and large overall size making it inconvenient to carry, this invention provides a novel plasma pulse lighter with single-needle corner flame emission.

[0004] To achieve the above objectives, the present invention specifically adopts the following technical solution: A novel plasma pulse lighter with single-needle angle ignition, characterized in that it includes a shell, a voltage boosting module, an oscillation drive module, a voltage multiplier module, a high-voltage output and ignition module, a power input module, a PCB board, a heat sink, a rocker switch, a micro switch, and an LED light; The boost module, oscillation drive module, voltage multiplier module, high voltage output and ignition module, and power input module are all fixedly integrated on the PCB board.

The anode of the high-voltage rectifier diode is electrically connected to the secondary coil of the boost coil winding, the cathode is electrically connected to the positive terminal of the high-voltage energy storage capacitor, and the negative terminal of the high-voltage energy storage capacitor is grounded.

[0011] Preferably, the insulating protective sleeve is fitted outside the root of the discharge electrode and is interference-fitted with the discharge electrode. The end of the insulating protective sleeve is located above the boost coil winding, and the discharge electrode is electrically connected to the positive terminal of the high-voltage energy storage capacitor.

The upper cover 12 is also rotatably installed on the outer shell 1.

[0026] Metal materials are preferred for mass production of the outer casing.

[0027] Working principle: When the rocker switch 9 is closed, the main power supply circuit of the whole machine is turned on. The lithium-ion battery 601 in the power input module 6 outputs 3.7V low-voltage DC power. After the current is filtered and regulated by the charge and discharge protection board 602, it is divided into two paths: one path is directly sent to the LED light 11 embedded in the button of the micro switch 10. The LED light 11 is powered on and illuminates, indicating that the whole machine is in standby power-on state; the other path is reserved to the input terminal of the micro switch 10, waiting for the ignition trigger signal. During this stage, the oscillation drive module 3, the boost module 2, and the voltage multiplier module 4 are not powered, and the whole machine has no high voltage output and is in a safe standby state.

[0028] Pressing the micro switch 10 activates the ignition power supply circuit. The low-voltage DC power, regulated by the charge / discharge protection board 602, is then transmitted to the oscillation drive module 3 via the micro switch 10. The oscillation drive module 3 contains a self-excited oscillating transistor, a base bias resistor, an adjustable resistor, a positive feedback unit, and a high-frequency filter capacitor, forming a self-excited oscillation circuit. Under the voltage division effect of the base bias resistor, the self-excited oscillating transistor quickly enters an alternating on / off switching state. Combined with the signal feedback effect of the positive feedback unit, it maintains continuous high-frequency oscillation of the circuit, converting the input stable low-voltage DC power into a high-frequency alternating current. The high-frequency filter capacitor simultaneously filters out high-frequency noise signals in the circuit, ensuring a pure and stable oscillation signal. The adjustable resistor adjusts the feedback strength and operating frequency of the oscillation circuit by changing its resistance value, thereby controlling the subsequent high-voltage output amplitude and indirectly regulating the arc intensity.

[0029] The high-frequency alternating current generated by the oscillation drive module 3 is directly supplied to the primary coil of the boost coil winding 201 of the boost module 2. After the high-frequency alternating current is applied to the primary coil, in conjunction with the magnetic coupling conduction effect of the magnetic core skeleton 202, a high-frequency high-voltage alternating current is induced at both ends of the secondary coil, completing the initial boost conversion from low voltage to high voltage. This high-frequency high-voltage alternating current is then input to the voltage multiplier module 4. Through the unidirectional conduction rectification of the high-voltage rectifier diode and the synergistic effect of the charging and discharging energy storage of the high-voltage energy storage capacitor, the voltage is doubled a second time, converting the high-frequency high-voltage alternating current into a DC high-voltage current with stable amplitude, providing stable high-voltage power for subsequent discharge ignition.

[0030] The stable DC high voltage output from the voltage multiplier module 4 is directly supplied to the discharge electrode 501 of the high voltage output and ignition module 5. The discharge electrode 501 adopts a single-needle angle structure, and the electric field intensity at the tip is sharply concentrated. When the tip voltage reaches the air breakdown threshold, the air between the electrode tip and the surrounding grounded parts is instantaneously ionized, forming a concentrated plasma arc, realizing single-needle angle ignition. At the same time, at the moment the micro switch 10 closes to trigger ignition, the internal circuit of the LED light 11 switches, and the light color changes, intuitively indicating that the current ignition working state is in progress. The insulating protective sleeve 502 wraps around the base of the discharge electrode 501 to isolate the high voltage current and avoid the risk of leakage.

[0031] When the micro switch 10 is released, the ignition power supply circuit is disconnected, the oscillation drive module 3 stops high-frequency oscillation, the boost module 2 and voltage multiplier module 4 have no high-voltage input, the voltage at the tip of the discharge electrode 501 drops rapidly, the plasma arc is extinguished, and the ignition process ends; at this time, the LED light 11 returns to its initial color and continues to show that the whole machine is in the power-on standby state; when the rocker switch 9 is closed, the whole machine's main power supply circuit is disconnected, the lithium-ion battery 601 stops supplying power, the LED light 11 goes out, the whole machine returns to the initial power-off state, and the charge and discharge protection board 602 simultaneously cuts off the power supply circuit, completing the shutdown and power-off process.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
