  • Patent number: 11191862
    Abstract: Air sterilizer generates ozone through ozone-generating part and control unit thereof, supplies ozone through air circulating fan, makes air flow by separate fan, and supplies hydrogen peroxide or limonene solution provided in cartridge type and vaporized. Air path is designed such that flow of ozone and flow of air of hydrogen peroxide or limonene solution are designed to maintain laminar flow state for smooth supply of the generated particles, turbulence inducing path for making turbulence easier when two streams meet each other is provided, separate air mixing space is created to create turbulent flow so that ozone and hydrogen peroxide, or ozone and limonene solution generate sufficient chemical reaction in this space to make OH radicals, and laminar flow path for spreading radicals or negative ions is provided, thereby sterilizing and purifying bacterial or indoor air suspended in air by the same principle as in the natural world.
