The invention discloses an automatic electronic igniter for a kitchen range. The igniter comprises a 12V direct current power supply, a photosensitive starting circuit, a square-wave generator, a boosted circuit and a high voltage spray point. The igniter is characterized in that a PNP type transistor 3AG12 is selected as a photosensitive tube VT1 in the photosensitive starting circuit; and the type of a power switch integrated block IC1 used in the square-wave generator is TWH8751. By using the automatic electronic igniter for the kitchen range, the 12V direct current power supply generates a high voltage pulse through an oscillating circuit; the automatic electronic igniter sparks instantly to form flames to complete an electronic ignition process, and a high voltage electronic ignition circuit is controlled by an optical signal signaled by fuel gas flames, the restart of the square-wave generator is controlled through the photosensitive pipe to output the high voltage pulse, therefore, the electronic ignition again is realized, fire hazards that the fuel gas flames extinguish accidentally are effectively avoided, the phenomenon of different operating methods and experience caused by different operating workers is avoided, and the common defect in a piezoelectric ignition mode is overcome very well.
