自动检测及连续点火的燃气控制电路

燃气灶具在燃烧过程中，因某种原因，意外熄火的情况时有发生，如果不及时关闭燃气通路或者重新点火燃烧，就会导致严重后果。针对重新点火燃烧的情况，设计出一种具有自动检测熄火及连续点火功能的安全型燃气灶具控制电路是可行的。它主要由电磁阀控制电路、熄火检测电路、点火控制电路及脉冲点火电路等组成，由二节电池供电。理论分析表明，这种安全型燃气灶具工作可靠、结构简单、适用。

Automatic Examination and Continuous Ignition Gas Control Electric Circuit

For certain reason suddenness flameout happens in Gas Burning Stove sometimes during the burning course and it will bring serious aftereffect if you do not switch off in time or restart again. On reignition case, this article introduces you to a control circuit of safety Gas Burning Stove with self- inspection for flameout and continuous ignition. It composes of circuit controlled by electromagnetic valve, flameout inspection circuit, ignition control circuit and pulse ignition circuit whose power supplied by two batteries. Theoretic analysis shows such safety Gas Burning Stove is reliable , simple in its confignration, using norreal electronic components and suitable for afterhours installation.
