Abstract

The invention relates to the field of devices for artificial fog generation for use in security systems. A fog generator comprises an evaporator with an electrical heating element, a reservoir for a liquid to be evaporated, a pump and a programmable electronic control unit. A novel feature is that the electrical heating element is a coil winded by an additional winding, and a silica wrapping is arranged around rounds of the coil. To supply the liquid to be evaporated from the reservoir through the pump and to the evaporator, the device comprises: tubular connections, an additional reservoir, a general line, a needle-like tube having slots. The programmable electronic control unit comprises a microcontroller, transistor modules and units, sensors connected to other device elements. The fog generator enables to increase evaporation area, speed; to avoid the evaporator's excessive energy consumption in a standby mode; to reduce device weight and sizes.
