[0007] In a further technical solution, a barrier is provided above the molding cavity.

[0008] In a further technical solution, the inner diameter of the enclosure gradually decreases from bottom to top.

[0009] In a further technical solution, the base and the molding cavity are detachably connected.

[0010] In a further technical solution, the wire outlet holes are evenly distributed on the top surface of the sugar silo near the edge.

[0011] In a further technical solution, the circuit board is a multi-layer stacked structure, and the winding coils of the multi-layer circuit boards are connected by wires.

[0012] In a further technical solution, the circuit board and the rotor are provided in multiple groups, and the multiple groups of the circuit board and the rotor are nested on the rotating shaft in sequence, and an isolation plate is provided between two adjacent groups of the circuit board and the rotor.

[0013] Multiple sets of circuit boards and rotors work together to drive the shaft to rotate, which can achieve a wider range of speeds and greater torque to meet higher requirements.

[0014] The beneficial effects of the present invention are:

[0015] The cotton candy machine of the present invention adopts a circuit board motor, with a PCB printed circuit board as the motor stator, and has a compact overall structure, a small volume, a light weight, a large speed range, higher portability, and can further improve the working efficiency of the cotton candy machine.
