Alcohol-based fuel ignition device

The utility model belongs to the technical field of igniters, and particularly relates to an alcohol-based fuel ignition device which comprises an ignition device body, a first oil pipe and an ignition needle, a protective shell is fixedly connected to the periphery of the ignition device body, a combustion cavity is connected to the inner side of the top of the protective shell in an embedded mode, and a second ceramic cap is connected to the middle of the combustion cavity in an embedded mode. The bottom of the second ceramic cap is fixedly connected with a heating piece, the front face of the top of the heating piece is in lap joint with an ignition needle, the other end of the ignition needle is fixedly connected with a first igniter, and the first igniter can improve the ignition rate of the alcohol-based fuel under the coexistence effect of the first igniter and the second igniter, so that the alcohol-based fuel is not prone to annihilation after being ignited; meanwhile, under the cooperation of the he
