Description

Mounting type telephone with receiver unit coated with photochemical catalyst

The present invention relates to a stationary phone coated with a photocatalyst on a transmitter and a receiver. More specifically, the photocatalyst is coated on the transmitter and the receiver, and by the photocatalytic chemical action with the lamp installed on the mounting part, the user can maintain the cleanliness at all times by preventing, sterilizing and disinfecting by the user's body contact and secretion such as saliva It relates to a stationary phone.

Titanium oxide, zirconium oxide, arsenic oxide, zinc oxide, tin oxide, cerium oxide, and the like are known as materials for inducing a photocatalytic reaction.

This photocatalyst generates OH radicals having a large energy equivalent to 120 kcal / mol by light irradiation as follows.

^{Ti + hυ → e - + h} + (1)

Ti-H ₂ O + h ⁺ → Ti-OH + O (2)

Ti-OH + h ⁺ → Ti + OH (3)

The energy generated by the OH radicals is greater than the various bond energies of the CC bond CH bond, CN bond, CO bond, OH bond and NH bond of the organic compound, and thus the organic matter can be easily decomposed by the action of decomposing these bonds. It can be used for the decomposition and sterilization of pollutants or odorous substances from harmful substances suspended in the air.

With the development of communication, various types of communication terminals are used. The stationary communication terminal, such as a public telephone, which is used by several people at the same time, is used in direct contact with the user's mouth and ears, so that it is easily contaminated by human secretions such as saliva and floating matters in the air, thereby providing an inappropriate sanitary environment. can do.

Conventionally, by maintaining the cleanliness by using artificial disinfection or cleaning method or by attaching the fragrance material separately to maintain a fresh feeling, but also the effect of sterilization is also uncertain.

The present invention forms a photocatalyst coating film on the body contacting part of a mobile phone, for example, a transmitter and a receiver, and a light emitting unit is installed on a cradle to irradiate the transmitter and the receiver at a place corresponding to the transmitter and the receiver. By decomposing and scattering bacteria and contaminants formed on the phone by means of keeping the phone clean and clean.

According to the present invention, a stationary telephone having a photocatalyst-coated hydration unit and a photocatalyst-coated receiver and a body for connecting and operating the transmitter and the receiver, wherein the cradle formed on the main body is provided with light to each of the transmitter and the receiver. There is provided a stationary communication terminal each provided with a light emitting unit.

The photocatalyst applied to the present invention may be titanium oxide, zirconium oxide, arsenic oxide, zinc oxide, tin oxide, cerium oxide, etc., but titanium oxide is preferable.

The present invention can be applied to all communication terminals such as public telephones and radios.

White, red, blue or infrared light may be used as the light source of the light emitting unit. Preferably, blue light of 400 nm or less is preferable. LED may be used as a light emitting unit to increase energy efficiency.

The light emitting unit may be turned on when the transmitter and the receiver are mounted on the holder of the main body to continuously emit light for a predetermined time or may be intermittently irradiated during the mounting. It is preferable that the light emitting portion includes a reflecting mirror so that light is irradiated to the transmitting and receiving portion efficiently.

Coating of titanium oxide is accomplished in a variety of ways. It can be directly coated on the said sending and receiving part by methods, such as CVD (chemical vapor deposition), ion plating, sputtering. Alternatively, a film of polyester, nylon, or the like is coated by the above method or the powder of photocatalyst is fixed on the film (tape) by a binder, and the tape is bonded to the sending / receiving part by a binder, or the sending / hydrating part It can be bonded to the plastic part of the thermal bonding method.

Hereinafter, the present invention will be described with reference to the drawings.

1 discloses the general chemistry and application of photocatalysts.

2A and 2B are explanatory diagrams of using the present invention. When the receiver is mounted on the main body of the public telephone, the light emitting unit is turned 'ON' and irradiates the transmitter and the receiver.

3A and 3B, the present invention is used in a general telephone. When the phone is mounted in the light emitting unit installed in the receiver and receiver receiving groove formed in the main body, the photocatalytic chemical reaction is activated by light irradiation on the surface of the transmitter and receiver.

The light irradiation is preferably made for a certain period of time by using the telephone and the 'light emitting unit' is 'ON' to be mounted on the cradle. Alternatively, the light emitting unit may blink periodically during the mounting.

According to the present invention, by photocatalytic chemical reaction of photocatalyst and light emitting part, telephones can be conveniently prevented from bacterial contamination, and odors can be removed.
