A high-voltage discharge needle with a flame induction function is characterized by comprising:
the device comprises a high-voltage signal generator 1, a step-up transformer 2, a high-voltage pack trigger 3, a high-voltage output transformer 4, a flame induction/high-voltage discharge needle 5, a reference signal generator 6, a reference signal transformer 7, a high-voltage amplitude stabilizer 8, a flame induction processor 9 and a circuit integrated controller 10;
the flame sensing/high voltage discharging needle 5 includes a flame sensing/high voltage discharging conductor 51, a ceramic insulating sleeve 52, an inner conductor 53 and a terminal 54.
The circuit integrated controller 10 is electrically connected with the high-voltage signal generator 1 and the flame induction processor 9, and the flame induction processor 9 is electrically connected with the high-voltage output transformer 4;
the high-voltage amplitude stabilizer 8 is electrically connected with the high-voltage output transformer 4, the flame induction processor 8 and the reference signal transformer 9;
the flame induction/high-voltage discharge needle 5 is electrically connected with the high-voltage output transformer 4;
the terminal 54 is electrically connected to an output port of the high voltage output transformer 4.
When a user starts the gas stove, for example, a gas knob of the gas stove is screwed, the circuit integrated controller 10 controls the high-voltage signal generator 1 to output a driving electric signal, the step-up transformer 2 steps up the driving electric signal, a trigger voltage is obtained at the high-voltage packet trigger 3, and the trigger voltage triggers the high-voltage output transformer 4 to perform high-voltage discharge on the flame induction/high-voltage discharge needle 5. After a user starts the gas stove, the mixing ratio of the gas and the air is adjusted by the gas valve, and the gas is guided to the stove core of the gas stove to overflow through the guide pipe, when the flame induction/high-voltage discharge needle 5 arranged near the stove core generates high-voltage discharge, the electric spark ignites the gas, so that the gas is stably combusted at the stove core.
The flame induction/high-voltage discharge needle 5 receives the high voltage output by the high-voltage output transformer 4 through the inner conductor 53, and generates an arc through high-voltage discharge on the surface of the flame induction/high-voltage discharge conductor 51 to ignite gas and realize ignition.
The reference signal generator 6 outputs a reference signal, and the reference signal transformer 7 outputs the reference signal to the flame induction/high-voltage discharge needle 5 through the high-voltage output transformer 4 for flame detection; the flame sensing/high-voltage discharging conductor 51 is triggered by the reference signal to generate a flame sensing signal, and the high-voltage amplitude stabilizer 8 acquires the flame sensing signal through the high-voltage output transformer 4 to limit the pressure of the flame sensing signal. Specifically, in order to realize flame detection, a flame sensing needle is required to be additionally arranged outside a high-voltage discharge needle of a conventional gas stove, and a reference signal for exciting the flame sensing needle is taken out from a high-voltage signal generator; here, the present embodiment integrates the function of flame detection into the high-voltage discharge needle, i.e. the flame sensing/high-voltage discharge needle 5, and meanwhile, the reference signal is independently generated by the reference signal generator 6, and the reference signal generator 6 and the high-voltage signal generator 1 are independent from each other, so that the reference signal is stable and undisturbed, and stable and accurate flame sensing can be ensured; in addition, because the flame induction and the high-voltage discharge are realized on the flame induction/high-voltage discharge needle 5, the flame induction needle does not need to be arranged independently, and the equipment cost and the process cost are reduced in the production link.
The flame sensing processor 9 obtains the flame sensing signal, analyzes the flame sensing signal to obtain the current flame state, and outputs the current flame state to the circuit integrated controller 10. When the current flame state received by the circuit integrated controller 10 shows that the flame is extinguished, an air supply cutoff instruction is output to avoid the escape of fuel gas. Specifically, in the using process of the gas stove, the reference signal generator 6 outputs a reference signal at a preset frequency to continuously perform flame detection, so that when the current flame state received by the circuit integrated controller 10 shows that the flame is extinguished, the circuit integrated controller 10 outputs an air supply cutoff instruction, the gas valve stops outputting the gas at the moment, the gas is prevented from overflowing to the external space after the flame is extinguished, and the potential safety hazard is eliminated.
Therefore, in the embodiment, the flame sensing/high-voltage discharge needle has both functions of flame sensing and high-voltage discharge, wherein the reference signal for realizing the flame sensing is generated by the reference signal generator, and is independent from the high-voltage signal generator for realizing the high-voltage discharge, so that the stable output of the reference signal can be ensured, the flame sensing needle does not need to be additionally arranged, the high-voltage ignition and the flame sensing can be stably realized through the flame sensing/high-voltage discharge needle, and the equipment cost and the process cost are reduced in the production link.
