Claims (10)

1. A mobile heating assembly, comprising:

a heating assembly unit for heating the aerosol-generating substrate article;

the moving component unit comprises a component moving mechanism and a motor component, the component moving mechanism is matched and connected with the heating component unit, and the motor component drives the heating component unit to move/rotate through the component moving mechanism;

the heating assembly unit and the motor assembly are both connected to a control circuit within the aerosol-generating device.

2. The mobile heating assembly of claim 1, wherein the heating assembly unit is an electromagnetic heating assembly unit comprising:

a heating tube for containing the aerosol-generating substrate article;

the electromagnetic coil is sleeved outside the heating pipe and is connected with the control circuit;

and the movable execution unit is matched and connected with the component moving mechanism, the electromagnetic coil is fixedly connected with the movable execution unit, or the electromagnetic coil and the heating pipe are both fixedly connected with the movable execution unit.

3. The mobile heating assembly of claim 2, wherein the mobile actuation unit comprises:

a coil space for accommodating the electromagnetic coil;

a heating pipe space for accommodating the heating pipe;
