Description

PORTABLE STERILIZING INSTALLATION USING UV-C CHIP LED USING UBI-SHIP CHIP

The present invention relates to an ultraviolet sterilizing apparatus, and more particularly, to an ultraviolet sterilizing apparatus capable of minimizing a system size and maximizing sterilization efficiency by converting a light source of a UV LED lamp having a relatively low wavelength of 380 nm into an ultraviolet light source having a wavelength of 254 nm The present invention relates to a portable ultraviolet sterilizing apparatus using a UV-CIS chip.

In general, when using utensils, bottles, and other products, various contaminants and bacteria multiply, and ultraviolet sterilizers that utilize ultraviolet rays as a sterilizer that can remove them are widely used. Most of these ultraviolet sterilizers are products that contain the products to be sterilized inside the main body and sterilize them by utilizing ultraviolet rays irradiated through ultraviolet lamps. However, there is a limit to the products that can be utilized in the case of such a stationary ultraviolet sterilizer.

That is, since sterilization can be performed only if it can be stored in the body of the sterilizer, most applications of the sterilizer for ultraviolet sterilization are specified. Typical examples are dish sterilizers and bottle sterilizers.

Accordingly, portable ultraviolet sterilizers have recently been introduced to solve these drawbacks. In the case of a portable ultraviolet sterilizer, it is general to form a reflector inside a body formed with a handle, and an ultraviolet lamp is installed in the inside of the body to be irradiated with ultraviolet rays. It is not necessary to store the product to be sterilized inside the main body, which is an advantage that it can be used for various purposes.

As an example, a portable ultraviolet sterilizing apparatus may be presented as in the accompanying patent document. As shown in FIG. 1, the main body 100 has an elongated box shape and is made of plastic resin. A printed circuit board for controlling the apparatus is built in the main body 100, and a handle 102 is formed at one end of the main body 100. The handle 102 is formed at an end of the main body 100 so as to have a width smaller than the width of the main body 100. A connecting point between the handle 102 and the main body 100 is provided with a lamp The operation panel 104 on which the buttons are disposed is located.

Therefore, the user can easily use the operation panel 104 while holding the handle. A power cable 106 for supplying electric power to the main body 100 is connected to the end of the handle 102, and the battery may be used as a power source.

An ultraviolet lamp 110 for irradiating ultraviolet rays is mounted on the bottom surface of the main body 100. A reflective lid 112 formed inside the main body 100 is positioned around the ultraviolet lamp 110. A surface of the reflective lid 112 is coated with a photocatalyst material, preferably titanium oxide (TiO 2).

The titanium oxide is processed into a fine powder form (nanoparticles), mixed with alcohol or water, and then coated on the surface of the reflector. At this time, the reflector is directly dipped in a mixture of titanium oxide and water or alcohol, Lt; 0 > C and fusing titanium oxide to the surface of the reflector.

Meanwhile, the ultraviolet lamp 110 is connected to the connection terminals 114 and 114 ', which are electrically connected to the printed circuit board and supply power. The infrared sensor is connected to the printed circuit board so that the ultraviolet lamp is turned on only when the back surface of the main body is within a predetermined distance from the product to be sterilized. . In addition, a mercury switch (not shown) is installed inside the main body so that power is cut off when the main body is inclined by a predetermined angle or more.

Here, the switch may be configured to selectively activate the operation of the mercury switch and the infrared sensor through a switch provided on the operation panel 104. That is, the operation of the infrared sensor or the mercury switch can be individually stopped or operated by depressing a switch provided on the operation panel 104, and this operation state can be detected by the user through a lamp provided on the operation panel 104 .

Meanwhile, although the ultraviolet lamp is directly exposed to the outside, an ultraviolet ray filter may be installed on the bottom surface of the main body to prevent the ultraviolet lamp from being exposed to the outside. The ultraviolet filter shields visible light and transmits only ultraviolet rays. When the bedding is sterilized through the ultraviolet filter, it is possible to prevent a mite living in the bedding hiding by the visible light. Therefore, pests such as ticks are irradiated with ultraviolet rays intact, and the sterilizing action can be maximized.

However, as described above, the conventional ultraviolet sterilization apparatus has a problem that not only the power consumption is increased due to the application of the direct-bulb type ultraviolet lamp, but also the manufacturing cost is increased due to the high voltage circuit for driving the lamp.
