Smart air sterilizer {Smart air sterilizer}

The present invention relates to a smart air sterilizer.

As shown in Figure 6, Republic of Korea Patent No. 2295502 (registration date: August 24, 2021, invention name: UVC-LED air sterilizer) has an internal space open on both sides, and an intake port 110 at the bottom. ) is formed, and the main body case 100 is formed with an exhaust port 120 at the upper portion; External air is intake and exhaust by communicating with the intake port 110 and the exhaust port 120, and a blower installation part 210 formed in a circular shape to communicate with the intake port 110 is disposed, and the upper part of the blower installation part 210 A first adsorption brush installation part 220 is disposed, which is formed in a circular shape to communicate with, and while one side is in communication with the upper part of the first adsorption brush installation part 220, the other side is formed in a circular shape to communicate with the exhaust port 120. A circular S free passage portion (200) consisting of a second adsorption brush installation portion (230); A side cover 300 that closes both open sides of the main body case 100; A blower 400 installed on the blower installation unit 210 and rotating by the operation of a drive motor 720 installed on the side cover 300 to intake and exhaust external air; An adsorption brush (500) is detachably installed on the first and second adsorption brush installation parts (220) and (230) to adsorb droplets and airborne viruses from the inhaled external air; A plurality of UVC-LED modules (600) are installed in the first and second adsorption brush installation parts (220) and (230) to sterilize droplets and airborne viruses adsorbed on the adsorption brush (500) in the circular S free passage part (200). ; A UVC-LED air sterilizer, characterized in that it consists of a switch 700 installed on the side cover 300 to operate the drive motor 720 and the UVC-LED module 600 with power supplied from the power supply unit 710. is included. While this conventional technology claims to be effective in discharging clean air by adsorbing droplets and floating viruses of external air sucked through the circular S-freezer to an adsorption brush and sterilizing them through UVC-LED, the configuration is complicated. There is a fundamental disadvantage that the sterilization effect is not good.

In addition, Republic of Korea Patent No. 2401778 (registration date: May 20, 2022, title of invention: air sterilizer using UV-C LED) has a tubular shape, and the tip of the tubular shape, as shown in Figure 7. or a housing in which side plates are combined at the rear end to provide a closed internal space, and a partition plate is inserted into the tubular interior to divide the internal space into a sterilization space and a circuit installation space; A PCB board installed on both inner surfaces of the sterilization space and on which LEDs are mounted at regular intervals along the length; It is mounted on the side plate located at the front and rear ends of the sterilization space and includes a blower equipped with an adjustable height (knob) that can adjust the rotation speed of the blowing fan, and the LED radiates light in the UV-C wavelength range. LEDs mounted on PCB boards installed on both side plates of the sterilizing space are arranged to be offset from each other, a reflector that reflects the light emitted from the LEDs is attached to the inner surface of the sterilizing space, and the blower is used to sterilize the sterilizing space. Installed on both side panels of the space, the first blower is installed on the side panel where air flows in, and the second blower is attached to the side panel where air flows out. When power is applied, the first and second blowers always operate at a speed exceeding the minimum speed. An air sterilizer using a UV-C LED is provided, which is configured to cool the air by emitting heat generated from the LED while operating while maintaining the air sterilizer. In this prior art, the LEDs arranged on both sides of the direction in which air flows in the sterilizing space inside the housing formed in a tubular shape are alternately arranged so as not to face each other, and the LEDs are arranged in a staggered manner on the inner surface of the sterilizing space inside the housing. Since each reflector is installed in a structure made of a material that reflects light, such as an aluminum mirror sheet, the sterilizing power and sterilizing efficiency can be maximized by maximizing the space where the light irradiated from both LEDs overlaps and lengthening the sterilizing distance. By installing speed-adjustable blowers at the front and rear ends of the space to control the speed of air flow within the sterilization space, the time that the air passing through the sterilization space is exposed to the light emitted from the LED is reduced. Because the air sterilizer is made as long as possible, the size of the air sterilizer can be small and the sterilization power and sterilization efficiency can be significantly increased. However, there is a fundamental problem that it is difficult to maximize the sterilization power because the air is sucked in and sterilized with LED lighting.

The purpose of the present invention, which was created to solve the above problems, is to provide a smart air sterilizer that can optimize air sterilization power by using an ultraviolet sterilizing lamp and an ionizer.
