Description

Photocatalyst antibacterial filter trash {Tio2 antibiotic filter wastebasket}

The present invention relates to a photocatalyst antimicrobial filter wastebasket (food waste bin), and more particularly, attaches an antimicrobial filter to the inner surface of a lid (cover) that is generally used. Coated with the used titanium dioxide photocatalyst (Tio2), UV lamp (UV LED) is formed on one side of the lid (cover) of the trash (food trash can) to irradiate the antimicrobial filter with ultraviolet light, so that the antibacterial and deodorizing function of the antibacterial filter itself is photocatalyst (Tio2) relates to a photocatalyst antibacterial filter trash bin (food waste bin) capable of performing oxidative decomposition, antibacterial and deodorizing functions of organic matter by photoreaction.

Trash cans that are currently used are used to collect garbage and food. However, wastes and foods are not immediately disposed of and collected until rubbed and then thrown away, and they are not only exposed to various odors and germs but also become the culprit of creating harmful environment. In the case of Utility Model 20-2004-0013553 and Patent Application 10-2004-0034750, which I filed on May 17, 2004, I use a transparent trash can lid on a trash coated with a photocatalyst or cover an ultraviolet lamp (UV LED) (Cover) Installed on the inner side to induce ultraviolet light into the trash. However, the photocatalyst (Tio2) is required to increase the cross-sectional area coated with the photocatalyst (Tio2) because the effect is increased as the coated cross-sectional area is large. In addition, contaminants on the inside of the trash convection to the top of the trash, as well as the need to provide a porous gathering place where odors and bacteria can collect.

Therefore, the present invention has been devised to solve the above problems, and attaches an antimicrobial filter to the inner surface of the lid of the conventional trash (food waste bin), and the surface of the antimicrobial filter using titanium dioxide photocatalyst (Tio2) Coated with UV light and UV lamp on one side of the lid of the trash can to irradiate antibacterial filter coated with photocatalyst (Tio2) to remove odor, inhibit bacteria and oxidize organic matter. Photocatalytic antibacterial filter bins (food waste bins). The antimicrobial filter is porous because it is a filter type, the cross-sectional area of the pores is much larger than the general surface area of the existing wastebasket lid, and can be removed by agglomerating bacteria and odors. When the porous cross-sectional area of the antimicrobial filter is wider, the cross-sectional area in which the photocatalyst (Tio2) can be coated is secured so that a greater amount of the photocatalyst (Tio2) is coated to exhibit more photocatalyst (Tio2) effects.

20: trash can body

30: UV lamp (UV LED)

100: antibacterial filter

In order to achieve the above object, the present invention attaches the antimicrobial filter 100 to the inner surface of the existing waste bin (food waste bin) 20, the lid (cover) 10, and the surface of the antimicrobial filter 100 using metatitanic acid. It is coated with titanium dioxide photocatalyst (Tio2) and UV lamp 30 is formed on one side of the lid (cover) of the trash (food waste bin) to irradiate ultraviolet rays to the antimicrobial filter 100 coated with the photocatalyst (Tio2). It has the characteristic formed by making it.

The reason why the antimicrobial filter 100 coated with the photocatalyst (Tio2) is attached to the inner surface of the trash (food waste bin) lid (cover) 10 and irradiated with UV light is because the titanium dioxide photocatalyst (Tio2) using the metatitanic acid is In order to ensure that sufficient ultraviolet light is irradiated on the photocatalyst (Tio2) coated antimicrobial filter 100 because it plays a role of a catalyst in the ultraviolet light band. In addition, the antibacterial filter 100 can suppress bacteria by its antibacterial activity, and the filter is porous, and its cross-sectional area is wide, so that a large amount of photocatalyst (Tio2) can be coated. In addition, a large amount of bacteria and odors are distributed through the pores, thereby increasing the time and effect of removing the bacteria and odors. Preferably, the antibacterial filter 300 employs a carbon fiber filter, and even if the antibacterial ceramic filter and the silver nanofiber filter are employed, the effect is excellent.

When described in detail with reference to the accompanying drawings an embodiment of the present invention as follows.

In order to form the photocatalyst antibacterial filter trash (food waste bin) of the present invention, the antibacterial filter 100 is attached to the inner surface of the trash can (food waste bin) lid (cover) 10, and the surface of the antibacterial filter 100 It is coated with a titanium dioxide photocatalyst (Tio2) using titanic acid, and forms an ultraviolet lamp (UV LED) 30 on one side of a lid (cover) of a trash can. Thus, when the garbage is filled in the trash (food waste bins), the porous antimicrobial filter 100 absorbs a large amount of bacteria and odors (the principle of absorption is absorbed by the natural antibacterial filter in the trash, and 휀 ( The antimicrobial filter 100 coated with titanium dioxide photocatalyst (Tio2) using metatitanic acid is irradiated with the ultraviolet rays of an ultraviolet lamp (UV LED) and has the unique characteristics of the photocatalyst (Tio2). Phosphorylation and reduction effect eliminate sterilization and odor. In addition, bacteria can be suppressed by the antibacterial activity of the double antibacterial filter 100 itself. At this time, the photocatalyst (Tio2) irradiated with UV light simply removes odors and bacteria based on various research data.

The photocatalyst is excited by light (ultraviolet rays) and is activated.
