Condensed aerosol fire extinguisher driving circuit suitable for electric spark starting

The invention relates to a condensed aerosol fire extinguisher driving circuit suitable for electric spark starting. The condensed aerosol fire extinguisher driving circuit comprises a filter circuit, an optocoupler isolation circuit, a relay control circuit and an anti-interference circuit, the relay control circuit comprises two relays, and each relay is provided with a fixed contact, a normally open movable contact and a normally closed movable contact. The positive and negative logic level output ends of an external MCU circuit are connected with the input end of the relay control circuit through the filter circuit and the optocoupler isolation circuit in sequence, and a normally open movable contact of one relay in the relay control circuit is connected with one input end of the anti-interference circuit. A normally open movable contact of another relay in the relay control circuit is connected with another input end of the anti-interference circuit. One output end of the anti-interference circuit is con
