Formation device

The utility model discloses a formation device. The formation device comprises: a formation cup comprising an air exhaust hole; the conversion mechanism is arranged on the side, provided with the exhaust hole, of the formation cup, and the conversion mechanism and the formation cup are movably arranged; the exhaust pipes are detachably mounted on the switching mechanism, and at least part of the exhaust pipes moving to the positions below the exhaust holes are communicated with the exhaust holes. In this way, the replacement efficiency of the exhaust pipe can be improved, and the problems that due to the fact that a heating device is additionally arranged, energy consumption is increased, and aging of the formation device is accelerated can be solved.
