DEVICE FOR IONIZING INDOOR AIR Russian patent published in 2023 - IPC A61L9/22 

FIELD: medical equipment.

SUBSTANCE: invention relates to a device for ionizing indoor air. The device contains an air duct with a fan unit located in it and connected to the electrical network, on the suction side of which there is a dust separator. The dust separator consists of a block of corona electrodes made in the form of grounded metal plates, between which corona electrodes connected to a voltage source are placed, and a dust settling unit made of parallel metal plates connected to a voltage source. On the discharge side of the fan unit there is a grid of ionizing electrodes with needle conductors placed in the nodes, connected to a voltage source to which the ionization control unit is connected. A part of the air duct from the suction side of the fan unit and from the discharge side of the fan unit to the ionizing electrode grid is made of metal. The block of corona electrodes and the dust settling block are fixed in two parallel dielectric plates; grounded non-ferrous metal grids are fixed to the fan block on the suction and discharge sides. On the side of the needle-shaped conductors of the ionizing electrode array, a shielding means is placed to neutralize the electric field, containing two grounded conductors in a dielectric shell. The air duct is fixed in a housing with air intake and air outlet openings to form a cavity in which a voltage source and an on/off unit connected to the electrical network connected to the fan unit and the voltage source are located. The ionization degree control unit contains a voltage regulation unit connected to a comparison unit with meters for the concentration of ionized oxygen molecules, and an operating mode switch connected to the voltage regulation unit and the comparison unit.

EFFECT: improvement of a device for ionizing air in a room, the ability to optimize the process of ionization of air oxygen molecules devoid of suspended particles, minimizing the negative effects of electric and electromagnetic fields, which leads to obtaining a given concentration of ionized air oxygen molecules while simplifying the design of the device and reducing its dimensions and weight, increasing safety and improving ease of maintenance.
