SWITCHING DEVICE Russian patent published in 2019 - IPC H01H47/02 

FIELD: ventilation and air conditioning.

SUBSTANCE: invention can be used for air purification from microbes and viruses. Relay (4) is switched on, the condenser is cut through normally closed contact of time relay (3) and normally open contact of relay (4). Discharging time of the capacitor is less than its charging. Therefore, neutral waves attracting to it are much more powerful than neutral waves repulsive from it. Thus, with switched off time relay (3) attracting neutral waves are formed. Repulsive neutral waves are generated with time relay. At switched off time relay, vacuum pump (13) operates. Room is cleaned of microbial air. Microbes and viruses are attracted to condenser. After a while, the time relay switches on and pressure pump (14) is started. Microbes and viruses repel the condenser and leave the room together with air.

EFFECT: creation of a switching device which cleans air in a room from microbes and viruses without an insert with a disinfecting coating.
