Safety systems for battery-supplied fogging device

A safety system for battery-powered fogging device, the safety system being designed to operate on a vaporization coil of a fogging fluid of the fogging device, the safety system comprising:

• at least one fusible wire, each placed at one end of the coil, the fusible wire, during the production of fog by the fogging device, being able to heat up both due to a Joule effect and via heat coming from the coil by thermal conduction, the fusible wire being therefore designed to melt when its temperature exceeds a melting threshold value, interrupting the power supply from the battery to the coil;
• at least one sensor designed to detect the temperature of the coil upon the passage of current in the coil;
• at least one control unit operatively connected to the at least one sensor;
• loading springs, designed to apply a mechanical tension to an electrical connection at each end of the coil, in order to make the intervention of the fuse wire more rapid and net;
• and
• a current sensing element, for example a ferromagnetic core coupled to a Hall effect sensor, the current sensing element being designed to measure the current of the coil, increasing the reliability of the system, the adoption of a magnetic flux tube allowing to position the sensor in a point well sheltered from the heat generated by the coil.
