That is, after the hot air blown out from the nozzle 409 heats the bottom of the target paper cup 500, it is limited by the outer wall of the bottom of the cup and the outer wall of the blowing head 401 and is blown out axially along the outer wall of the blowing head 401. In this way, the hot air with residual heat passes through the through hole 413 and is blocked by the flange portion 410 located in the cavity 412. In this way, the residual hot air can be The hot air is discharged from the upper opening of the cavity 412 of the air guide shell 411, and because a suction effect is formed at the through hole 413 when the hot air is discharged from the upper opening of the cavity 412, the surrounding cold air is sucked in from the through hole 413, and then a cooling air flow is formed at the lower part of the air guide shell 411 and the outside of the sliding air duct 404 to cool the outer walls of the two components, effectively avoiding heat transfer to the box body 100, so that the transmission components in the box body 100 have a stable operation effect, so that the cup bottom heating device in this embodiment has the technical effect of energy saving and emission reduction.
