DEVICE FOR BACTERICIDAL AIR TREATMENT Russian patent published in 2021 - IPC A61L9/14 B05B17/06 

FIELD: air treatment.

SUBSTANCE: invention relates to ultrasonic aerosol devices designed for spraying liquid substances, it can be widely used for bactericidal air treatment. The device for bactericidal air treatment contains a spray chamber with a built-in piezoelectric converter, a transistor, a choke, a phase-shifting circuit including a resistor, a transformer and a capacitor forming a parallel oscillating circuit with the primary winding of the transformer, a secondary winding of the transformer connected to the base of the transistor through a frequency-stabilizing piezoelectric element, while the primary winding through a separating capacitor is connected to the emitter of the transistor, a matching circuit formed by the capacitor, throttle and autotransformer, shift voltage supply circuit, a capacitor connected between the base and the emitter of the transistor. The device is additionally equipped with an ionization unit consisting of a resistor, a Zener diode, a capacitor, silver electrodes, and a power supply unit consisting of a lowering transformer, a diode bridge, and a capacitor.

EFFECT: invention provides an increase in the efficiency of the device by obtaining a disinfectant solution directly in the spray chamber of the device.
