Abstract: A safety system for a battery-powered fog generator is described, designed to operate on a vaporization coil (2) of a fogging fluid; the safety system includes: a fuse wire (1), each placed at one end of the coil (2), suitable for heating both due to a Joule effect and through heat coming from the coil (2) by thermal conduction, the fusible wire (1) being therefore designed to melt when its temperature exceeds a melting threshold value, interrupting the power supply from the battery to the coil (2); a sensor (6) designed to detect the temperature of the coil (2) when current flows in it; and a control unit (7) operatively connected to the sensor (6).

Abstract: A fog-generating system (1) is described, comprising: a tank (5) containing fog-generating fluid; a pump (3) connected to the tank (5) to withdraw the fog-generating fluid therefrom; a serpentine (2) connected to the pump (3) to receive the fog-generating fluid pumped by the pump (3), the serpentine (2) being divided into a first section (A) connected to the pump (3) and a second section (B) connected to the first section (A) and designed to emit dry fog (7) as output; a battery (6) connected to the serpentine (2) to pass electric current inside the serpentine (2) and to supply the pump (3); a differential amplifier (11) connected to the second section (B); and a threshold comparator (13) which, upon exceeding a certain voltage, a stop index of the serpentine (2) in the second section (B), breaks the supply to the pump (3).
