The invention discloses a low-cost high-output columnar pyrotechnic airbag gas generator which comprises a pipe body. An ignition assembly, a blasting basin, a filter screen and a gasket are sequentially arranged in the pipe body from left to right; the ignition assembly is located at the left end of the pipe body and connected with the pipe body in a sealed manner; the blasting basin, the filterscreen and the gasket are all located at the right end of the pipe body; the blasting basin is fixedly connected with the pipe body, the left end of the blasting basin is provided with an opening, andthe right end of the blasting basin is sealed and provided with a plurality of evenly-distributed notch grooves; the pipe body is provided with a plurality of gas vents corresponding to the filter screen in position; and a powder cavity is formed in the pipe body and located between the ignition assembly and the blasting basin, and automatic ignition powder and gas generation powder are arrangedin the powder cavity. The low-cost high-output columnar pyrotechnic airbag gas generator has the advantages that the structure is simple, assembling is convenient, the number of parts is smaller, andthe cost is lower.
