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.

An electric glue gun includes a housing, a glue tube holder arranged at a front end of the housing, and a push rod disposed on the housing and moveable forward and rearward relative to the glue tube holder. A control board, a main switch, an electric motor and a transmission mechanism are provided inside the housing. The main switch is electrically connected to the control board for controlling power on/off, the electric motor is electrically connected to the control board to drive the push rod to move forward or rearward via the transmission mechanism. The electric glue gun further includes a sensor switch for facilitating control of a forward/rearward movement stroke of the push rod, and the sensor switch is electrically connected to the control board, such that the control board determines whether the push rod is moved to a limit position based on information feedback from the sensor switch.
