Cryogenic smoke appliances and smoke suction systems with overhead heating components

The invention discloses a low-temperature smoke appliance having a hanging heating part, includes a housing having a mounting chamber formed therein, a heating element located in the installation chamber, a resilient assembly mounted in the mounting chamber for limiting the depth of insertion of the cigarette and providing a restorative force to the cigarette, an electromagnetic induction coil installed in the housing and a control module for supplying a high-frequency oscillating current to the electromagnetic induction coil, at least a part of the heating element is located in a space surrounded by the electromagnetic induction coil; after being coupled with the cigarette inserted into the installation chamber, the heating element moves a preset distance along the cigarette insertion direction opposite to the cigarette insertion direction under the restoring force of the elastic component, so as to be suspended in the installation chamber in a suspended state, thereby reducing heat transfer and preventing t
