Integrated ignition device

The utility model discloses an integrated ignition device. Six air injection holes which are 1.5 mm in diameter are formed in the head portion of a gun barrel body and connected with a flame holding cover, a relative narrow ignition space is isolated for an ignition electrode, only little gas amount can meet an ignition requirement, and fifty small holes which are 6 mm in diameter are evenly distributed in the flame holding cover and have an air distribution function and a combustion stabilizing function. The flame holding cover is arranged at the position of an air injection outlet, gas is injected forwards at high speed through the six air injection holes which are 1.5 mm in diameter, a cylindrical shape flame is easy to form, the flame is concentrated, temperature strength is high, and main fire can be rapidly ignited. The integrated ignition device is simple in structure and long in service life.
