The present disclosure discloses a flamed-based vacuum generator, including a shell and a combustion assembly, where the shell has a cavity, the cavity being a space having at least one opening, and the combustion assembly includes a combustible object and an igniter, the igniter being configured to ignite the combustible object, the combustible object generating a flame in the cavity, and the flame extinguishing in the cavity. In the present disclosure, through in-depth study of the internal mechanism of vacuum generated by flame combustion, it is found that the extinguishing process of a flame is the key to the generation of vacuum, and a larger flame and more sufficient combustion indicate a higher vacuum pressure generated in the cavity after the flame is extinguished.
