Fog-generating system equipped with safety and regulating devices of the flow-rate of its fog-generating fluid

A fog-generating system (1) comprising:

• at least one tank (5) containing fog-generating fluid;
• at least one pump (3) connected to said at least one tank (5) and designed to withdraw said fog generating fluid therefrom;
• at least one serpentine (2) connected to said at least one pump (3) and designed to receive said fog-generating fluid pumped by said pump (3), said serpentine (2) being divided into a first section (A) connected to said pump (3) and a second section (B) connected to said first section (A) and designed to emit dry fog (7) as output;
• and
• at least one battery (6) operatively connected to said at least one serpentine (2) and designed to pass electric current inside said serpentine (2) and to supply said pump (3), wherein a supply of said pump (3) is taken from a resistive divider obtained from said second section (B) of the serpentine (2), and, till the serpentine (2) remains dry, it is uniformly heated and its resistance proportionally increases, while, when the fog-generating fluid gets in contact with said first section (A), its heating and the following status change prevent the first section (A) from being overheated, limiting its resistance increase, and the second section (B), instead, is affected only by its vapour phase, and will be heated more, increasing the voltage at its terminals, so that the pump (3) has a supply voltage as higher as the second section (B) is more “dry”, and consequently increases the flow-rate till a balance point is found between temperature distribution and flow-rate.
