Description

Virus sterilization apparatus {Virus sterilization apparatus}

The present invention relates to a virus sterilizing device. More specifically, the present invention relates to a virus sterilizing device, and more specifically, by using a first light source unit and a second light source unit formed to output UV light having different wavelength ranges, the sterilization object located in front and the air contained in the inside are introduced. This relates to a virus sterilizing device that can sterilize a wide area in a shorter time by sterilizing viruses.

The recent emergence of new viruses that have not been seen in the past, such as swine flu, MERS, and COVID-19 viruses, has raised a red flag for human life and health. The characteristics of this new virus are that it is rapidly contagious and its mortality rate is higher than that of past viruses, so interest is focused on preventive measures against the spread of new diseases caused by infectious viruses.

In addition, due to the characteristics of the new virus, it is mainly spread in the form of droplets through the respiratory tract, and this virus in the form of droplets provides a contaminated environment in a specific place, causing rapid progress from secondary spread to the recent nth spread. It is characteristic.

Moreover, hepatitis caused by contact with the saliva of people infected with the virus is becoming serious enough that it cannot be overlooked, and such contact is especially common with things that people use a lot, such as the user's hands, clothes, bags, and furniture, and in places where many people gather. It poses a particular threat to the spread of infectious diseases due to its diverse transmission routes.

Therefore, medical authorities are using the method of regularly spraying disinfectants in areas and spaces where there is a lot of contact between people as a preventive measure to prevent the spread of infectious diseases. This disinfectant is effective in suppressing the active activity of infectious disease pathogens by removing them, preventing their spread, and reducing their motility.

Meanwhile, the spraying of disinfectants is carried out by people using simple spray devices under the leadership of government authorities, and the disinfectants contain toxic substances such as benzalkonium chloride, sodium hypochlorite, and slightly acidic substances. It is made up of hypochlorous acid (slightly acidic hypochlorous acid), so quarantine workers are wearing gas masks and quarantine suits while providing quarantine services. In other words, benzalkonium chloride, sodium hypochlorite, and slightly acidic hypochlorous acid water are used for disinfecting humidifiers, and because they contain toxic substances that are very harmful and dangerous to the human body, they are harmful to the health of workers even if they are wearing quarantine suits, and are used after quarantine. Since you cannot enter the building for 24 hours, you have to vacate the entire building.

As a workaround to solve this problem, a virus sterilizing device using an ultraviolet lamp that irradiates ultraviolet (UV) light has been developed. However, ultra-high-density ultraviolet rays cannot be used because they are subject to regulation due to ozone generation, and medium-density or high-density ultraviolet lamps are used. These lamps have a short effective distance and narrow range, so sterilizing devices are installed throughout the quarantine space. However, there is a problem that the sterilization effect can be achieved only when it is operated for a long time, more than 24 hours, by allowing air from every corner into the sterilization device. Additionally, when a relatively large fan is operated to increase the amount of air inflow, loud noise causes discomfort to workers and people around them.

Therefore, in order to perform efficient space quarantine sterilization, multiple sterilization devices equipped with small-scale fans must be installed in various locations or the sterilization device must be operated 24 hours a day, but this is not efficient and has the problem of increasing initial installation costs.

Accordingly, there is a need to develop a virus sterilizing device that can be installed in large buildings such as movie theaters, department stores, schools, and public buildings to efficiently sterilize large spaces.

Embodiments of the invention are provided to more completely explain the invention to those skilled in the art. Accordingly, the shapes and sizes of elements in the drawings may be exaggerated for clearer explanation.

FIG. 1 is a diagram schematically showing the internal configuration of a virus sterilizing device according to an embodiment of the present invention, FIG. 2 is a diagram showing the front of the virus sterilizing device shown in FIG. 1, and FIG. 3 is a view showing the front of the virus sterilizing device shown in FIG. 1. This is a diagram showing the rear of the virus sterilizing device, and FIG. 4 is a diagram showing UV light output from the second light source unit of the virus sterilizing device shown in FIG. 1.

1 to 4, the virus sterilizing device 100 includes a body portion 110, a first light source portion 120, a second light source portion 130, an intake/exhaust fan 140, and a light concentrator 150. ), and a control unit 160.

The body portion 110 may have a receiving space 110a formed therein, and a portion of the front may be made of a material that allows light to pass through. For example, the body portion 110 may be formed in a square or cylindrical shape with a receiving space 110a formed therein, and a cover portion formed to be mutually separable to facilitate repair and replacement of parts placed therein ( 111) and a cover portion 112 may be provided. At this time, the cover part 111 may be formed of an opaque material so that the UV light output from the first light source unit 120, which will be described later, is not transmitted to the outside, and the front of the cover part 112 may be formed on the second light source unit (to be described later). 130) can be made of a transparent material so that the UV light output from the device can be transmitted well.

The first light source unit 120 is disposed at the inner rear of the body unit 110 and irradiates UV light into the body unit 110 to the air flowing into the body unit 110 through the intake and exhaust fan 140, which will be described later. Contained viruses can be sterilized. For example, the first light source unit 120 outputs UV light using a plurality of ultraviolet lamps 121 arranged left and right and up and down, and can sterilize viruses contained in the air flowing into the body unit 110. .

The second light source unit 130 is disposed in front of the first light source unit 120 and radiates UV light from the inside of the body unit 110 forward to remove viruses contained in the air flowing into the body unit 110. After sterilization, viruses contained in the sterilization object located on the outer front of the body portion 110 can be sterilized. For example, the second light source unit 130 may include a plurality of UV laser diodes 131 arranged left and right and up and down, and a UV laser diode support member 132 that supports the plurality of UV laser diodes 131. In addition, the UV light emitted from the UV laser diode 131 enables secondary sterilization of viruses contained in the air flowing into the body portion 110 and sterilization of viruses contained in the sterilization object.

Meanwhile, UV light output from the first light source unit 120 may be provided in a size of 150 to 300 nm, and UV light output from the second light source unit may be provided in a size of 300 to 450 nm.

That is, the UV light output from the second light source unit 130 can be provided in the size of UV-A with a wavelength range of 300 to 450 nm, which means that if the wavelength is less than 300 nm, disinfection efficiency cannot be improved. However, because the light does not travel far, it cannot be disinfected over long distances. Accordingly, when sterilizing using UV-A, which has a relatively large wavelength range, it is possible to smoothly sterilize even objects located at a distance of 1 meter or more.

Additionally, the first light source unit 120 may be formed to output UV-B and UV-C having a smaller wavelength range than the second light source unit 130, which means that the first light source unit 120 is located inside the body unit 110. Since it is intended to sterilize viruses in the air flowing into the air, there is no risk of burns and the wavelength band does not have to be large. Additionally, UV-B and UV-C have a sterilizing effect that is approximately 1,000 times greater than that of UV-A, allowing more efficient sterilization.

The intake and exhaust fan 140 sucks in external contaminated air and supplies it from the rear to the front of the body unit 110, allowing the air sterilized by the first light source unit 120 to pass through the second light source unit 130 to the body unit. (110) Can be discharged to the outside. That is, it is possible to sterilize viruses contained in the air by circulating air outside the body portion 110 through the intake and exhaust fan 140.

At least one intake/exhaust fan 140 is provided to circulate external air, and the circulation of air allows cooling of heat generated when the first light source unit 120 and the second light source unit 130 are driven. do. That is, air is introduced from the first light source unit 120 to the second light source unit 130 through the intake and exhaust fan 140, which not only helps sterilization but also performs a cooling function. At this time, an outlet may be formed in the front of the body portion 110 so that the air sucked in through the intake and exhaust fan 140 can be discharged to the outside.

The light concentrator 150 is disposed between the body 110 and the second light source 130, and condenses the UV light irradiated from the second light source 130 and provides it to the sterilization object located in front of the body 110. can do. For example, the light concentrator 150 is provided with the same number of UV laser diodes 131 and includes a plurality of convex lenses 151 arranged to face each other, and a convex lens support member supporting the convex lenses 151 ( 152) may be included. That is, one convex lens 151 can converge UV light irradiated from one opposing UV laser diode 131 and provide it to the sterilizing object.

In this way, low-density UV light scattered through the light concentrator 150 can be concentrated at high density and irradiated to the sterilizing object, thereby increasing sterilizing efficiency. In particular, when the second light source unit 130 is made of a UV laser diode 131, the UV light provided from the UV laser diode 131 may be spread at a certain angle, and it is necessary to prevent the spread of this light and form a focus. To this end, UV light is condensed through the light concentrator 150.

The control unit 160 may control the operation of the first light source unit 120, the second light source unit 130, and the intake and exhaust fan 140. For example, the control unit 160 selects and controls the intensity and operation time of each UV light output from the first light source unit 120 and the second light source unit 130, or controls the RPM and RPM of the intake and exhaust fan 140. You can control it by selecting the operation time, etc.

Meanwhile, if the UV light provided from the second light source unit 130 is exposed to the human body for a long period of time, it may cause aging such as burns, pigmentation, and wrinkles. In order to solve this problem, the virus sterilizing device 100 further includes a human body detection sensor 170 for detecting a human body located in front of the body portion 110, and the control unit 160 includes a human body detection sensor 170. If a human body is detected, the power to the second light source unit 130 may be cut off.

The human body detection sensor 170 consists of an infrared sensor, a biosignal sensor, a motion sensor, etc., and can detect a certain range of infrared rays, biosignals, and human body movements emitted from the human body. Accordingly, when the human body of a worker or a nearby person is located in front of the virus sterilizing device 100, the control unit 160 detects this through the human body detection sensor 170 and turns off the power to the second light source unit 130. By doing so, safety during use can be increased.

FIG. 5 is a diagram illustrating a change in the position of the light concentrator due to the position adjustment member of the virus sterilizing device shown in FIG. 1.

Referring to FIG. 5 , the virus sterilizing device 100 may further include a positioning member 180 that adjusts the position of the light collecting part 150 in the front-back direction within the body part 110. In this way, as the position adjustment member 180 allows the light concentrator 150 to move in the front-back direction, that is, in the direction of irradiation of the UV light output from the second light source unit 130, the focal position of the UV light can be moved farther or closer. By allowing the sterilization to form, it is possible to sterilize the sterilization object placed at the desired location.

The positioning member 180 may include a guide rail 181 and a rail coupling portion 182.

The guide rails 181 are disposed on both sides of the light collection unit 150, and long rail grooves may be formed in the front-back direction on the surface facing the light collection unit 150.

The rail coupling portion 182 may be formed to protrude on both sides of the light collecting portion 150 and be coupled to the rail groove of the guide rail 181. Specifically, the rail coupling portion 182 is formed to protrude on both sides of the convex lens support member 152 and can be coupled to the rail groove of the guide rail 181. Although not shown, it may be a screw motor or spring member that can move in the forward and backward directions. It is coupled to can adjust the position of the light collecting part 150 in the forward and backward directions.

Accordingly, when the rail coupling portion 182 is pushed forward or pulled backward using the position adjustment switch 183, which is exposed to the outside of the body portion 110 and linked with a screw motor or spring member, the light collecting portion ( 150) can move in the front-back direction along the guide rail 181. At this time, the screw motor or spring member is connected to the position adjustment switch 183 provided on the outside of the body portion 110, and can be moved forward or backward by on/off control of the position adjustment switch 183.

According to the present invention, the virus sterilizing device 100 may further include a switch member 191 and a trigger 192.

The switch member 191 is elastically supported on the body part 110 and has a power supply unit for supplying power to the first light source unit 120, the second light source unit 130, and the intake and exhaust fan 140 depending on whether or not it is pressed. Can be turned on/off. Accordingly, power can be provided to the first light source unit 120, the second light source unit 130, and the intake and exhaust fan 140 only when the switch member 191 is pressed by the operator.

At this time, in order to prevent operation when the operator accidentally presses the switch member 191 or when a person other than the operator presses the switch member 191, a trigger is formed on the outside of the body portion 110 to be rotatable in the forward and backward directions. (192) may be provided. That is, the trigger 192 can be linked to the switch member 191 to turn the power supply on/off according to the rotation direction.

For example, the trigger 192 may be formed to interfere with the switch member 191 and be rotatable only when the switch member 191 is pressed. That is, the trigger 192 is in contact with the switch member 191 and is formed so that it cannot rotate until the switch member 191 is pressed, but after the switch member 191 is pressed, the interference is released and it can rotate. do. Accordingly, since the trigger 192 can be rotated only when the switch member 191 is pressed, accidents such as burns caused by UV light due to malfunction can be prevented in advance.

FIG. 6 is a diagram showing the sterilization sequence of the virus sterilization device shown in FIG. 1.

As shown in FIG. 6, when the intake and exhaust fan 140 located at the rear of the body unit 110 is driven, contaminated air outside the body unit 110 passes through the intake and exhaust fan 140 and enters the body unit 110. may be introduced. Viruses contained in the air introduced in this way are first sterilized in the first light source unit 120 and then secondarily in the second light source unit 130, and can be discharged through an outlet located in the front of the body unit 110. At this time, the UV light provided from the second light source unit 130 passes through the body unit 110 and reaches the object to be sterilized. Due to the UV light of the second light source unit 130, the UV light is transmitted to the front outside of the body unit 110. It is possible to sterilize viruses on the surface of the sterilizing object located.

As described above, the virus sterilizing device 100 is provided with a first light source unit 120 and a second light source unit 130 that output UV light with different wavelength ranges to sterilize the sterilizing object located in front and to sterilize the sterilizing object located in front. Sterilization efficiency can be improved by sterilizing viruses contained in the air.

In addition, by forming the second light source unit 130 to output UV light with a wavelength range of 300 to 450 nm forward, UV light is output farther than UV light with a wavelength range of less than 300 nm, so that it can be used to transmit UV light at a greater distance. It becomes possible to sterilize the object to be sterilized.

In addition, since low-density UV light scattered through the light concentrator 150 can be concentrated at high density and irradiated to the sterilizing object, sterilizing efficiency can be increased.

In addition, by providing a human body detection sensor 170, when the human body of a worker or a nearby person is located in front of where UV light is irradiated, safety during use can be increased by blocking the irradiation of UV light.

In addition, in order to prevent operation when the operator accidentally presses the switch member 191 or when a person other than the worker presses the switch member 191, a switch member 191 and a trigger ( 192), it is possible to prevent accidents such as burns caused by UV light due to malfunction.
