DEVICE FOR OBTAINING DISINFECTANT SOLUTION Russian patent published in 2021 - IPC A61L9/14 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to devices for bactericidal air treatment. The device 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, the secondary winding of the transformer. The secondary winding is connected to the base of the transistor via a frequency-stabilizing piezoelectric element. The primary winding is connected to the transistor emitter via a separation capacitor. The device contains a matching circuit formed by a capacitor, a choke, and an autotransformer, a bias voltage supply circuit, and a capacitor connected between the base and the emitter of the transistor. The device is equipped with an ionization unit, a working fluid level alarm unit, and a power supply unit. The ionization unit contains a stabilizer, a micro-display unit, a variable resistor, and silver electrodes. The working fluid level alarm unit is assembled according to the circuit of a composite transistor. The power supply unit contains a step-down transformer, a diode bridge, and a capacitor.

EFFECT: efficiency of the device is improved.
