Description

Portable Intelligent UVC LED Sterilizer{Portable Intelligent Sterilizer using UVC LED}

The present invention relates to a portable intelligent UVC LED sterilizer, and more particularly, to a portable intelligent UVC LED sterilizer that can easily check the light irradiation time of the UV LED required for sterilization.

There are news that hundreds of times more bacteria in the toilet have been detected on the computer's keyboard and in the instruments that children blow in their mouths, and bacterial infection is caused by these contaminated objects. Infections are transmitted through the air or by contact, but most are usually bacterial infections by contact.

In order to prevent such bacterial infection, various sterilization products including ultraviolet sterilizers have been released. The previously released ultraviolet sterilizer uses ultraviolet lamps to irradiate the surface of the object to be sterilized. However, the existing UV sterilizer has a short life, and has a disadvantage of high power consumption and high maintenance cost. In particular, it is not suitable for a portable product due to its large volume.

On the other hand, the UVC (Ultraviolet C) LED sterilizer has the advantages of small size and long service life, but there is no high-power product, so it is necessary to use the UVC LED sterilizer for a long time to obtain the desired sterilization effect, and the product is also expensive. . As described above, the existing UVC LED sterilizer has a weak output, thereby increasing the sterilizing power by irradiating a number of UVC LED sterilizers to the sterilizing object for a long time. However, since there is no quantified value for sterilization, the user intuitively irradiates the UVC LED to the sterilized object, but the actual sterilization is not clearly known.

In addition, the UVC LED sterilizer includes a light emitting unit, but is exposed to the outside and thus is vulnerable to contamination and damage, and thus has a disadvantage in that its life and performance decrease as it is used for a long time.

In addition, the UVC LED sterilizer is very dangerous when the LED is overexposed to the human eye or skin. Infants and toddlers who are mischievous are exposed to this risk, but the seating measures are incomplete.

The problem to be solved by the present invention is to propose a UVC LED sterilizer capable of recognizing whether a sterilized object is sterilized.

Another problem to be solved by the present invention is to propose a portable UVC LED sterilizer.

Another problem to be solved by the present invention is to propose a UVC LED sterilizer capable of protecting a light emitting unit, a sensor unit, and the like from external impact.

Another problem to be solved by the present invention is to propose a UVC LED sterilizer having a structure that infants and toddlers cannot easily operate.

To this end, the portable intelligent UVC LED sterilizer of the present invention has a bottom case in which a USB connection port is formed; It is formed on the top of the bottom case, a battery case mounted with a battery, a lower case mounted with a main control unit that controls to emit UV LEDs according to the operation of a push button switch; An inner frame formed on an upper portion of the lower case and mounted with the UV LED in a predetermined depth; The inside is empty so that the inside frame can be drawn inside, and includes an upper case that moves upward and downward with at least a portion of the inner frame drawn by elastic members formed at the top and inside of the inside frame.

The portable intelligent UVC LED sterilizer according to the present invention can intuitively recognize whether the sterilized object is sterilized by calculating the distance at which ultraviolet light is irradiated to the sterilized object and displaying the irradiation time according to the calculated irradiation distance.

In addition, the portable intelligent UVC LED sterilizer is easy to carry in a triangular prism shape or a quadrangular prism shape, and the UV LED, distance sensor, and display are exposed to the outside only when the upper case is moved upwards, so that they are usually protected from external shocks. Parts can be protected.

In addition, when only the push button switch is operated, the UV LED does not emit light, and the infant and the infant are embodied in the present invention by emitting the UV LED only when the push button switch and the limit switch for detecting that the upper case is moved upward are simultaneously operated. It has the effect of blocking the UVC LED sterilizer to control easily.

The above-described and further aspects of the present invention will become more apparent through preferred embodiments described with reference to the accompanying drawings. Hereinafter will be described in detail so that those skilled in the art through this embodiment of the present invention can be easily understood and reproduced.

Figure 1 shows the sterilization illumination according to the ultraviolet irradiation distance of the portable intelligent UVC LED sterilizer according to an embodiment of the present invention. According to FIG. 1, it can be seen that the shorter the UV irradiation distance of the portable intelligent UVC LED sterilizer, the more the sterilization illuminance increases.

In general, the time (t) required to sterilize 99.9% of bacteria can be calculated by Equation 1 when the ultraviolet irradiation distance from the sterilized object is known.

[Equation 1]

Time (t) = 99.9% UV energy required for sterilization (㎼ㆍsec/㎠)/Sterilization illumination at the irradiation distance (㎼/㎠)

Explained further, if the distance to the sterilizing object can be known at the point of irradiating ultraviolet rays, the time (t) required to sterilize the bacteria up to 99.9% can be calculated.

For example, to sterilize the influenza virus at a distance of 5 cm, assuming that the sterilization intensity at the point where the UVC LED is 5 cm away is 2,000 (㎼/㎠), sterilize 99.9% of the influenza virus by irradiating UV light for 3.2 seconds. Can. Of course, in this case, in order to sterilize 99.9% of the influenza virus, ultraviolet energy of 6,600 (㎼·sec/cm 2) is required, and the required time is calculated by Equation (2).

[Equation 2]

Time(t) = 6,600(㎼ㆍsec/㎠)/2,000(㎼/㎠) = 3.2sec

Figure 2 shows a portable intelligent UVC LED sterilizer according to an embodiment of the present invention. Hereinafter, a portable intelligent UVC LED sterilizer according to an embodiment of the present invention will be described in detail with reference to FIG. 2.

According to FIG. 2, the portable intelligent UVC LED sterilizer 200 includes a bottom case, a USB connection port, a bottom case, a battery, a battery case, a PCB, a MCU (main control unit), a push button switch, an inner frame, an ultraviolet LED, and an ultraviolet LED. Includes reflector, distance sensor, display, limit switch, upper case and elastic member. Of course, other configurations than the above-described configuration may be included in the portable intelligent UVC LED sterilizer 200 proposed by the present invention.

The bottom case 202 is located on the bottom surface of the portable intelligent UVC LED sterilizer 200, and is formed of a metal material or a plastic material. The USB connection port 204 is formed on the bottom case 202, and the USB terminal is connected. The portable intelligent UVC LED sterilizer 200 receives power from the outside using a USB terminal or charges power to the built-in battery 206.

The lower case 210 is formed on the top of the bottom case 202, and a plurality of components are mounted in an empty interior. In the context of the present invention, the lower case 210 may be integrally formed with the bottom case 202 or may be formed separately. The shape of the lower case 210 may be configured in a polygonal column shape of various shapes such as a triangular prism shape or a quadrangular prism shape. In addition, if necessary, the lower case 210 may be formed of an antibacterial metal material.

The battery 206 is mounted inside the battery case 208 and is connected to the USB connection port 204 to charge power supplied from the outside. The power charged in the battery 206 supplies power to a number of parts including the UV LED 222 by the operation of the push button switch 212.

The battery case 208 is mounted inside the lower case 210 and functions to protect the battery 206 mounted therein from external impact.

The PCB 214 is also mounted inside the lower case 210, and a number of components including the MCU 216 are mounted. The MCU 216 controls the operation of the portable intelligent UVC LED sterilizer 200 and controls the operation of a number of components constituting the portable intelligent UVC LED sterilizer 200.

When the push button switch 212 is formed on the lower case 210, the ultraviolet LED 222 emits light by manipulation. In connection with the present invention, the ultraviolet LED 222 emits light when the UV LED 222 does not emit light only by the operation of the push button switch 212, but when the limit switch 228 is operated simultaneously. Of course, when the push button switch 212 is operated, information on this is transmitted to the MCU 216, and the MCU 216 combines the information provided from the limit switch 228 to determine whether the UV LED 222 emits light or not. Decide.

As described above, the battery 206, the battery case 208, the PCB 214, and the pushbutton switch 212 are mounted or formed on the lower case 210, and the MCU 216 is mounted on the PCB 214. .

Hereinafter, the inner frame 218 will be described. The inner frame 218 is positioned at the top of the lower case 210 and has a size that can be mounted inside the upper case 230 that moves up and down.

An ultraviolet LED 222, a display 220, a distance sensor 226, and a limit switch 228 are formed on the inner frame 218. In relation to the present invention, the UV LED 222 and the distance sensor 226 are located on the same surface, and the display 220 is preferably located on the opposite side, but if necessary, the display 220 may be formed on the side surface. have. As described above, the UV LED 222 emits light by the operation of the push button switch 212 and the limit switch 228 according to the control command of the MCU 216, and when either switch is not operated, the UV LED 222 ) Does not emit light.

The UV LED 222 is not formed on the surface of the inner frame 218, but is formed on a point drawn at a certain depth from the surface of the inner frame 218 to protect the UV LED 222 from external impact during light irradiation. do. To this end, the inner frame 218 is formed with a hole in which a side is drawn at a predetermined depth, and an ultraviolet LED 222 is mounted on the formed hole. In addition, the hole that is introduced into the inner frame 218 by a certain depth has a trapezoidal shape.

The UV LED reflector 224 is formed on the side of the trapezoidal shape, and reflects the ultraviolet light irradiated to the side surface so that the ultraviolet light is irradiated to the front side. The UV LED 222 emits light by receiving power charged to the battery 206.

The distance sensor 226 measures the distance from the object to be sterilized. The distance sensor 226 measures the distance to the sterilization object in a set periodic unit, and the measured distance is displayed on the display 220 located opposite. The distance sensor 226 may apply any one of various distance sensors, including an ultrasonic distance sensor. The distance sensor 226 is also formed on the inner frame 218 inserted at a certain depth. The depth introduced into the inner frame 218 to mount the distance sensor 226 and the depth introduced into the inner frame 218 to mount the UV LED 222 are the same. In this way, the MCU 216 is configured to make the depth inserted on the inner frame 218 to mount the distance sensor 226 and the depth drawn on the inner frame 218 to mount the UV LED 222 the same. The irradiation time of the calculated UV LED 222 can be accurately calculated.

The distance sensor 226 and the display 220 may be driven by the operation of the push button switch 212 or may be operated by separate buttons. Alternatively, the distance sensor 226 and the display 220 may be driven by the touch of the display 220, or may be driven by a control command of the MCU 216.

The UV LED 222 formed on the inner frame 218, the UV LED reflector 224, the display 220, and the distance sensor 226 normally maintain a state not exposed to the outside, but the upper case 230 When is withdrawn to the top, it is exposed to the outside.

A limit switch 228 is formed on the upper side of the inner frame 218, and is operated when the upper case 230 moves to the upper side. When the upper case 230 moves to the top, the limit switch 228 is operated, and when the push button switch 212 is operated in this state, the ultraviolet LED 222 emits light according to the control command of the MCU 216. Therefore, when the push button switch 212 is operated while the upper case 230 is not moved to the top, the UV LED 222 does not emit light.

The upper case 230 moves up and down based on the inner frame 218, and moves upward in response to an operation of a button (not shown). An elastic member 232 is formed on the top of the inner frame 218. In more detail, one side of the elastic member 232 is in close contact with the top of the inner frame 218, and the other side is in close contact with the inside of the top of the upper case 230. Accordingly, when a button not shown is operated, the upper case 230 moves upward with respect to the inner frame 218 by the elastic force of the elastic member 232. The shape of the upper case 230 has the same shape as that of the lower case 210.

Of course, when the user presses the upper case 230 to the bottom, the upper case 230 moves to the bottom and is fixedly fastened to the inner frame 218. As described above, according to the present invention, parts formed on the inner frame 218 by the vertical movement of the upper case 230 are exposed or not exposed. However, the limit switch 228 is located on the upper case 230 and the inner frame 218 even if the upper case 230 moves to the top, but is not exposed to the outside.

Figure 3 shows a state in which the upper case is moved to the bottom according to an embodiment of the present invention. As illustrated in FIG. 3, when the upper case moves to the bottom, components formed on the inner frame are not exposed to the outside, whereby components formed on the leading inner frame are protected from external impact or the like.

Hereinafter, the function of the MCU will be described in detail.

The MCU stores information on the sterilization required energy for each germ and the sterilization intensity of the UVC LED by distance. The MCU displays the irradiation time required for sterilization for each bacterium by using the distance information to the sterilized object provided from the distance sensor. As described above, since the sterilization intensity is different according to the distance from the sterilization object, the MCU stores the information of the sterilization intensity according to the distance from the sterilization object. In addition, the MCU does not store information about one bacterium, but stores information about at least two bacteria. Therefore, the display also does not indicate the irradiation time for one bacterium, but the irradiation time for at least two bacteria respectively. 1 also shows information on four types of bacteria.

Figure 4 shows the overall shape of the portable intelligent UVC LED sterilizer according to an embodiment of the present invention. In particular, Figure 4 shows a state in which the upper case is moved to the top.

As illustrated in FIG. 4, when the upper case moves to the top, the inner frame is exposed to the outside, and the UV LED, distance sensor and display formed on the exposed inner frame are exposed.

In particular, when the shape of the lower case is a triangular prism shape in relation to the present invention, a push button switch is formed on the corner of the triangular prism, and an UV LED and a distance sensor are formed in the same direction. To this end, the inner frame is not formed in a triangular prism shape, but a cross section is formed in a trapezoid shape.

An ultraviolet LED and a distance sensor are formed on the front side of the inner frame having a trapezoidal cross section, and a display is formed on the rear side.
