Description

Sanitary appliance cover which formed photocatalyst and ultraviolet lamp {Tio2 with UV LED Cover}

The present invention relates to a sanitary appliance cover formed with a photocatalyst (Tio2) and an ultraviolet lamp (UV LED), and more particularly, to one side of a cover of sanitary appliances (sink stand, toilet bowl, trash bin, etc.) that are generally used. By forming a power jack to supply power and forming an ultraviolet lamp (UV LED) to supply ultraviolet light to the inside, and by coating a titanium dioxide photocatalyst (Tio2) using metatitanic acid, a titanium dioxide photocatalyst using metatitanic acid Hygiene to form photocatalyst (Tio2) and UV lamp (UV LED) that can perform organic oxidative decomposition, antibacterial and deodorization function by photoreaction of (Tio2) (Tio2 + hv-> e- + Tio2 (h +)) An apparatus cover is provided.

The sanitary appliance cover that is currently used in general was used only for the purpose of preventing the smell of the sanitary appliances (sink, toilet bowl, trash bin, etc.) from coming out. Therefore, it could not effectively suppress the propagation of various odors and bacteria, and was the main culprit of making the living environment unpleasant.

In addition, kitchen sinks are not used to make or clean food and sanitarily use, or they are not effectively blocked by drains, so they are always exposed to germs, which adversely affects the health of the family. It was an element to provide. In the case of the double toilet, many harmful bacteria are breeding because they are always exposed to the dirty environment, and no breakthrough methods for removing them are proposed. In addition, the toilet seat is a place where human skin directly touches, and many people are exposed to dirty environment because it is inconvenient to wash the touched area immediately.

Therefore, the present invention was created to solve the above problems, to form a UV lamp (UV LED) for supplying ultraviolet rays to the inner surface of the sanitary appliance cover (cover), thereby using a titanium dioxide photocatalyst (Tio2) ) To provide a sanitary appliance cover that forms photocatalysts (Tio2) and UV lamps (UV LEDs) that can remove odors and effectively inhibit bacteria and oxidatively decompose organic matter.

<Description of Symbols for Main Parts of Drawings>

10: UV lamp (UV LED)

20: Titanium dioxide photocatalyst (Tio2) coating film using metatitanic acid

30: power jack

40: power supply adapter jack

50: Power supply adapter (DC 6V)

In order to achieve the above object, the present invention forms a power supply jack 30 that can supply power to one side of the sanitary appliance cover (cover) and to form an ultraviolet lamp (UV LED) 10 for supplying ultraviolet light on the inside, This has a feature formed by coating a titanium dioxide photocatalyst (Tio2) 20 using metatitanic acid.

The reason for forming the UV lamp (UV LED) 10 on the inner surface is to form because the titanium dioxide photocatalyst (Tio2) using the metatitanic acid plays a role of a catalyst in the ultraviolet region.

The power jack 30 is converted into DC 6V by the power supply adapter 50 at all times to supply power to the infrared lamp (UV LED) (10).

When explaining the embodiments of the present invention based on the accompanying drawings as follows.

EXAMPLE

1 is a perspective view (1-1) showing an inner surface of a sanitary appliance cover in which a photocatalyst (Tio2) coating and an ultraviolet lamp (UV LED) are formed according to the present invention, and an outer perspective view (1-2) in which a power supply jack is formed. ) And a perspective view (1-3) showing a power supply adapter.

2 is a perspective view illustrating a disconnection circuit connection diagram for supplying power to an ultraviolet lamp (UV LED) according to the present invention.

Figure 3 is a perspective view showing an application example of the sanitary appliance cover formed with a photocatalyst and an ultraviolet lamp according to the present invention, Figure 3-1 applied to the lid of the general trash, the case applied to the drain cover to the kitchen utensil sink Fig. 3-2 and an example diagram (3-3) applied to the seat cover of the toilet bowl.

In order to form a sanitary appliance cover formed by forming a photocatalyst (Tio2) and an ultraviolet lamp (UV LED) of the present invention, first, the required number of ultraviolet lamps (UV LED) 10 are formed on a circuit board. At this time, the connection of the circuit follows the disconnection diagram of FIG. 2. After forming a cover of the sanitary appliances for the intended use to insert the UV lamp (10 LED) substrate and to coat the sanitary appliance cover with a titanium dioxide photocatalyst (Tio2) using metatitanic acid. do. Of course, the ultraviolet rays must be discharged into the cover, so that the ultraviolet rays of the UV lamp (UV LED) are perforated to flow into the cover. Thereafter, the power supply adapter jack 40 of the power supply adapter 50 is inserted into the power jack 30 formed at one side of the cover, and then the ultraviolet lamp (UV LED) is turned on and used.

As a result, the sanitary appliance cover which forms the photocatalyst Tio2 and the UV lamp UV LED effectively removes odors and bacteria inside the cover.

At this time, the principle of eliminating odor and bacteria is briefly explained based on various research data. (This content is a part of data of Utility Model 20-2004-0013553, filed on May 17, 2004). is.)

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

◎ Anatase Tio2

E = hv = hc / λ

E = 3.2 eV

h (Plank's Cnst) = 4.135 eV sec

C (Light velocity) = 3 x 10 (10 powers) cm / sec

λ = Wave length, m

λ = 380 nm

◎ Synchronization of chain reaction by light

Tio2 + hv-> e- + Tio2 (h +)

◎ Reaction by free electrons

e- + o2-> o-2

o-2 + H + <-> HO2

◎ Reaction by hole

h + + H2O-> OH + H +
