According to the present invention, it is possible to provide a shield plate with a sterilizing function for the purpose of disinfecting indoor air and enhancing sterilizing power.

It is an outline drawing of the shield plate with a sterilizing function according to the embodiment of this invention. It is sectional drawing of the pedestal part 12 of the shield plate with a sterilizing function and the transparent two-layer shield plate 1 with a gap by embodiment of this invention.

Hereinafter, the shield plate with a sterilizing function according to the embodiment of the present invention will be described with reference to FIGS. 1 and 2. In all the drawings below, the dimensions and ratios of the components are shown with different values for ease of understanding.

As shown in FIGS. 1 to 2, the shield plate with a sterilizing function of the present embodiment includes a two-layer shield plate with a gap 1, a gap 2, a small hole / slit 3, an air tank portion 4, and an air inlet 5. It is composed of a filter 6, a fan 7, a deep ultraviolet LED 8, a wiring outlet portion 9, a wiring connection portion 10, a control unit 11, and a stand unit 12. The ultraviolet LED 6 is preferably an LED having a peak wavelength in deep ultraviolet rays (UV-C: 100 to 280 nm), but may be an LED having a peak wavelength in near ultraviolet rays (about 300 to 400 nm), or 280 to. It may be an LED having a peak wavelength at 315 nm, or it may be an LED having a peak wavelength at 315 to 400 nm. The two-layer shield plate 1 with a gap may have a configuration of three or more layers. The two-layer shield plate 1 with a gap is made of a transparent resin, but may be made of transparent or translucent glass or an opaque metal, resin, wood, or bamboo material. The control unit 11 is a control panel that controls the fan 7 and the deep ultraviolet LED 8. The air tank portion 4 is provided inside the pedestal portion 12, but when the two-layer shield plate 1 with a gap is held by using the hanging portion, the air tank portion 4 may be provided inside the hanging portion. The air tank portion 4 may be provided at a position connected to the two-layer shield plate 1 with a gap by a pipe or tube through which air can flow. The gap 2 is about 3 cm, but it may be 3 cm or less as long as there is an interval for air to flow, or it may be larger than 3 cm.

In the shield plate with a sterilizing function of the present embodiment, the surroundings are sealed, and the indoor air is taken from the air intake port in the air tank connected to the multi-layer transparent shield plate having a gap between the layers so that air can flow. It passes through the filter, is taken in by the air blown by the fan, is temporarily stored in the air tank, and this air is sterilized by the irradiation of the deep ultraviolet LED installed inside the tank, and the sterilized air in this air tank is sterilized. , It is sent to the gap of the connected multi-layer transparent shield plate, and the sterilized and purified air is discharged into the room through the small holes or slits provided in the multi-layer transparent shield plate. The multi-layer transparent shield plate has, for example, a two-layer structure, has a gap between layers, is sealed around, and has a structure in which air can flow only at a connection portion with an air tank. In this way, the air in the room is taken in by the fan installed in the air tank → the air is sterilized by the LED → the sterilized air is discharged into the room through the gaps of the multi-layer transparent seal plate, and the sterilization function is provided. The shield plate promotes sterilization and purification of indoor air, and can provide comfortable and safe air. The shield plate with a sterilization function of the present embodiment is highly resistant to virus bacteria having a strong infectivity with a deep ultraviolet LED by repeatedly sterilizing and sterilizing the air in the room by the shield plate with a sterilization function. It is safe for the human body because it is likely to die and be returned to the room, so it does not irradiate the human body directly with light. In addition, by installing a bamboo charcoal powder film inside the air tank, it is possible to exert the functions of deodorizing air and controlling humidity. In addition, since this device has a thin shield plate structure, it does not take up much space indoors and can be installed in a wide range of applications. In this embodiment, the method is to install it on a stand, but it is also possible to hang it from above. Further, although the multilayer transparent shield plate is a transparent resin, it is also possible to select transparent, translucent glass or an opaque material such as metal, resin, wood or bamboo. In addition, the shape of the above-mentioned multi-layer transparent shield plate can be implemented in other shapes such as a quadrangle, a circle, and an ellipse, and the shape is determined by the product design according to the customer's preference and application. It may be done.

According to the present embodiment, for example, a deep ultraviolet LED having a short wavelength of 250 nm to 320 nm, which can kill up to 99.9% of the highly infectious new coronavirus, is used from the room to the air tank for a certain period of time. By irradiating the air taken in by the air, the bacteria in the air are sterilized, and by discharging the air into the room, a sterilizing air sterilization and a shield plate with a sterilization function that can be sterilized are provided. Can be provided. In addition, since the place where it is installed is thin, it can be installed as a shield plate for the purpose of partitioning between people in the office or reception desks of hospitals, government offices, hotels, etc. It is possible to kill strong virus bacteria with a high probability, which will lead to the solution of the global virus infection problem.

Further, according to the present embodiment, the virus bacteria and the like floating in the air in the room are put into an air tank that also serves as a stand connected to the transparent shield plate through a filter from the air supply port, and this air is introduced. The air that has been completely killed by irradiating the air with the deep ultraviolet LED built in the tank is discharged into the room through a small hole or slit provided in the multi-layer transparent shield plate having a gap between the multi-layers. In this way, the air in the room is removed by repeating the cycle of taking in air → sterilizing the air in the air tank → discharging the air into the room from the small holes or slits provided in the shield plate via the gaps between the layers. Bacteria and bactericidal power can be enhanced.

In industry, in daily life, the present invention is widely installed between people such as offices and reception desks to prevent the splashing of virus bacteria, etc., to sterilize indoor air and infect. It can be used as a shield plate with a sterilizing function that allows the air that has killed powerful virus bacteria to circulate indoors and live comfortably.
