Abstract
Description
Technical Field
[0001] This utility model relates to igniters, and more particularly to a high-energy igniter with adjustable energy. Background Technology
[0002] High-energy igniters are devices used for igniting oil and gaseous fuels. Their working principle involves boosting the input power supply, converting it to DC, and charging a capacitor. Once the voltage is sufficient, a high-voltage discharge from an ignition gun ignites the fuel. The ignition energy of a high-energy igniter has a significant impact on the ignition success rate. Higher ignition energy results in higher discharge energy and a higher ignition success rate. However, excessively high discharge energy can easily damage components in the circuit, such as significantly reducing the lifespan of the ignition gun head. Therefore, the required ignition energy varies greatly depending on the application scenario. Conventional high-energy igniters, due to their constant-voltage charging and discharging control logic, cannot achieve adjustable ignition energy, resulting in very low flexibility.
[0003] Furthermore, in conventional high-energy igniters, the capacitor charging voltage, which determines the discharge energy, is typically difficult to adjust. This is because the discharge timing is entirely determined by the high-voltage discharge tube. The high-voltage discharge tube is a passive discharge device; when the external voltage reaches the discharge voltage, the internal gas breaks down, causing discharge. Once the model of the high-voltage discharge tube is determined, the charging energy is also fixed, making it impossible to manually set or adjust.
[0004] Therefore, it is necessary to optimize its structure to overcome the above-mentioned defects. Utility Model Content

[0025] The power sampling component includes:
[0026] The sampling circuit has its input terminal connected to the power supply via a line, and it samples the fluctuation state of the power supply.
[0027] The discharge control components include:
[0028] A light-emitting diode (LED) is connected to a charge-discharge control component, which controls the LED's light-emitting state.
[0029] The phototransistor works in conjunction with a light-emitting diode (LED) and is connected to a silicon controlled rectifier (SCR) via a circuit. The LED illuminates the phototransistor, and the phototransistor outputs a photocurrent, which turns on the SCR.
