TECHNICAL FIELD [0002] Conductive Touch Pen For Having Sterilization Function And Apparatus For Sterilization Using The Same

The present invention relates to a capacitive touch pen, and more particularly, to an electrostatic touch pen having a sterilization function and a sterilization device using the touch pen.

In general, touch panels used in electronic devices such as mobile phones are applied to pressure-sensitive touch panels and capacitive touch panels. A capacitive touch panel that can be used without a separate touch pen is widely applied.

In capacitive touch panels, when the capacitance value of the capacitive pad changes according to a minute current, a signal is inputted, and a minute current flows through the human body. designed and manufactured. When the fingertip touches the touch panel, the minute current flowing through the human body and the capacitance value of the fingertip change the capacitance value on the capacitive pad constituting the touch panel, so that the position where the capacitance value is changed can be read.

In addition, although the capacitive touch panel can input a signal with a finger, it is still essential to use a touch pen for more detailed input or for doubling of ease of use and input speed. Accordingly, various types of touch pens that can be used in capacitive touch panels have been proposed.

The most typical capacitive touch pen is composed of a pen body that can be gripped by a user's finger and a touch body formed of an elastic material at the end of the pen body as in Patent Document 1 (Korean Patent Publication No. 10-09846666). In this case, the touch body in contact with the touch panel is formed of a soluble rubber material including a conductive material.

On the other hand, Patent Document 2 (Korean Patent Publication No. 10-1665730) proposes a multi-purpose writing instrument in which a writing pen and a touch pen are provided together in a casing in a multi-purpose writing instrument having a plurality of pen nibs, such as a multi-color ballpoint pen. have.

In addition, Patent Document 3 (Korean Patent Publication No. 10-2071449) has a writing pen, a touch pen and a sterilizing pen inside a casing with a pen inlet and outlet on one side, so that the touch pen and writing pen functions as well as the sterilization function are implemented. We propose a multi-purpose writing instrument that can be used.

The capacitive touch pen 10 according to the present invention having the above-described configuration is usually worn on the user's neck by using the necklace 11 after separating the touch unit 300 from the joint 200 when necessary. A user command is input to the touch panel by touching the touch body 310 at a desired position of the capacitive touch panel.

After using the touch unit 300 as a capacitive touch pen in this way, it is recombined with the joint unit 200 , and when the operation button 160 of the sterilization unit 100 is pressed, the battery 130 power is supplied to the LED board 150 . The UV LED 151 is transmitted, and the UV LED 151 is operated to emit light for sterilization of the UV wavelength band through the hole 171 of the diaphragm 170 . Accordingly, the light for sterilization of the ultraviolet wavelength band emitted through the aperture 170 of the sterilization unit 100 is irradiated to the touch body 310 of the touch unit 300 to sterilize the touch body 310 .

On the other hand, the sterilization unit 100 of the electrostatic touch pen 10 according to the present invention can be used not only for sterilization of the touch unit 300 but also as a portable sterilizer for sterilization of various other products or places. That is, if sterilization is required, after separating the sterilization part 100 from the joint part 200 , the aperture 170 of the sterilization part 100 is positioned in the area to be sterilized, and the operation button 160 is operated.

In addition, the capacitive touch pen 10 according to the present invention may be applied as a sterilization device for sterilization of portable items such as smartphones or cosmetics by combining with a sterilization port 400 as shown in FIG. 4 . .

5 is a perspective view of a sterilizing apparatus according to a preferred embodiment of the present invention, and FIG. 6 is a longitudinal cross-sectional view taken along line A-A of FIG. 5 .

5 and 6 , the sterilization port 400 according to the present invention has a socket 420 for coupling the sterilization unit 100 of the capacitive touch pen 10 to the top of the arched roof 410 . The left and right stands 430a and 430b supporting the arched roof 410 are respectively formed at both ends of the lower end of the arched roof 410 . Accordingly, a sterilization space 440 that can accommodate a small portable article 500 such as a smart phone or cosmetics is formed in the sterilization port 400 as shown in FIGS. 5 and 6 .

Accordingly, the sterilization unit 100 is separated from the capacitive touch pen 10 of the present invention, and the iris 170 of the sterilization unit 100 is coupled to the socket 420 of the sterilization port 400 so that it faces downward. A new sterilization device capable of sterilizing the portable article 500 is created by doing so.

In the case of this sterilization device, the operation button ( 160), the UV LED 151 of the sterilization unit 100 is irradiated with light in the ultraviolet wavelength band for sterilization through the aperture 170, thereby sterilizing the portable article 500 in the sterilization space 440 as a whole. . In particular, in order to further increase the sterilization efficiency of the sterilization port 400, it is preferable to form a reflective surface by coating the inner surface of the sterilization space 440 of the sterilization port 400 with a material that reflects ultraviolet light.

In particular, in the case of the sterilization port 400, since the ultraviolet light emitted through the aperture 170 of the sterilization unit 100 is collected into the sterilization space 440 so as not to be diffused or reflected and leaked to the outside, the sterilization unit 300 ) can further increase the sterilization efficiency compared to UV light irradiation only.
