SWITCHING DEVICE Russian patent published in 2018 - IPC H01H47/02 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the field of electrical equipment and it can be used to clean air of microbes and viruses. Multi-vibrator (2) output is connected to the relay (3) winding. Second power supply (4) is connected to the capacitor (5) via the relay (3) normally closed contact. Capacitor (5) is connected to the resistor (6) via the relay (3) normally open contact. When charging the capacitor (5), its neutral field changes, neutral waves are generated. When at the multi-vibrator (2) output there is no voltage, the electric current does not flow to the relay (3) winding. Through of the relay 3 normally closed contact, the electric current from the second power source (4) is supplied to the capacitor (5). Capacitor (5) is charging. Capacitor (5) is installed in the pipe (7) on the stops (8). Into the pipe (7) insert (9) is installed. Insert (9) walls have a disinfecting coating (10). Capacitor (5) drives the microbes and viruses to the insert (9) walls. Getting on the disinfecting coating 10, microbes and viruses die. Technical result is the possibility to charge the capacitor from an increased voltage of 100–300 V. Furthermore, in the proposed switching device it is not necessary to heat and cool the air.

EFFECT: that is why the costs of air cleaning of microbes and viruses will be less.
