Cotton candy preparing device

A cotton candy preparing device, comprising:

• a main body portion;
• a rotary pot that is incorporated in the main body portion and that has a pot upper portion and a pot bottom portion, the rotary pot having a rotation shaft and a gear wheel plate attached to the rotation shaft;
• a pan portion that is mounted above the main body portion so as to surround at least the pot upper portion,
• wherein the pot upper portion is provided above the main body portion so as to project upwards therefrom and the pot upper portion is configured to separate from the pot bottom portion,
• wherein the rotary pot has a detecting switch for detecting a cutoff of an electrical connection to a control integrated circuit that is configured to drive a heater or a motor when the pot upper portion is removed from the pot bottom portion;
• a pot mounting base portion having a bearing plate at an upper end thereof, wherein the pot mounting base portion is provided at a bottom plate portion of the main body portion to thereby support rotatably the rotation shaft of the rotary pot, wherein the gear wheel plate is fixed to the rotation shaft in such a way that the gear wheel plate faces the bearing plate and is parallel therewith;
• three electrode rings each having a circumferential annular shape centered at the rotation shaft, wherein the three electrode rings are provided on an upper surface of the bearing plate;
• a plurality of metallic contacts provided on a lower surface of the gear wheel plate so as to be brought into contact with the three electrode rings;
• and
• a power supply switch arranged in series with the detecting switch in a circuit via two electrode rings of the three electrode rings.
