Description

Technical Field

[0001] The following embodiments relate to walk-through disinfection devices that can be installed in visitor access facilities such as airports, ports, and passenger stations to sterilize passengers’ bodies and personal belongings. Background Technology

[0002] Since the beginning of 2000, we have witnessed a series of infectious disease pandemics, including SARS, Alzheimer's disease, Ebola, and MERS-CoV. These pandemics have resulted in devastating loss of life and severe economic damage worldwide. Furthermore, the recent COVID-19 pandemic represents an unprecedented infectious disease crisis, underscoring the importance of disease prevention and control.

[0003] As an example, airports, as the nation's frontline gateways, serve as conduits for the entry and spread of infectious diseases. Therefore, airports should be equipped with comprehensive quarantine and epidemic prevention systems to prevent the spread of infectious diseases. Typically, when passengers enter or leave the country, queues form at immigration checkpoints, customs, and quarantine points, potentially making it difficult to manage passenger flow within the airport. However, limitations in epidemic prevention technology and insufficient quarantine personnel can lead to suspected cases of infectious diseases being overlooked during airport quarantine procedures and successfully passing through exit or entry points, ultimately allowing the disease to spread into the community. Furthermore, existing epidemic prevention procedures relying solely on quarantine personnel are time-consuming.

[0004] In this context, there is a need for an effective epidemic prevention system that can shorten the waiting time for passengers waiting for quarantine procedures and reduce the burden on quarantine officers by setting up devices that automatically conduct epidemic prevention for passengers and baggage in airports.

[0005] Furthermore, when existing quarantine personnel directly carry out epidemic prevention measures, there is a risk that these personnel may also become infected. Therefore, a non-contact epidemic prevention system is needed.

[0006] Furthermore, infectious agents causing infectious diseases exist in various forms, including bacteria, viruses, protozoa, fungi, and parasites. The optimal preventative measures vary depending on the specific infectious agent. If only specific infectious agents are addressed during preventative measures, it may be impossible to adequately manage the spread of other infectious agents. Therefore, a multi-tiered preventative system capable of simultaneously addressing the prevention requirements of multiple infectious agents is needed, but such a system does not yet exist.

[0007] This requirement is not limited to airports. Similarly, it applies to tourist access facilities such as ports, train stations, and bus terminals. Furthermore, in the event of a crisis characterized by a pandemic caused by an infectious disease, multi-purpose facilities with high foot traffic, such as large shopping malls, supermarkets, exhibition halls, and concert venues, will also be considered for such facilities.

[0008] The background technology described above was acquired or understood by the inventors in the process of deriving the disclosure of this application, and is not necessarily publicly known technology that was disclosed to the general public before this application. Summary of the Invention

[0034] The following is for reference Figures 1 to 3 Detailed description of the walk-through epidemic prevention device 1. For reference, Figure 1 This is a perspective view of one embodiment of the walk-through epidemic prevention device 1. Figure 2 To observe from direction "A" Figure 1 A three-dimensional view of the second sterilization section 120 in the walk-through epidemic prevention device 1. Figure 3A block diagram illustrating the structure of a walk-through epidemic prevention device 1 according to an embodiment.

[0035] Referring to the attached diagram, the walk-through disinfection device 1 can be used at the arrival and departure gates of an airport. The walk-through disinfection device 1 provides multi-level disinfection as passengers walk through its interior, employing low-temperature plasma and ultraviolet sterilization, air sterilization, and high-temperature plasma and ultraviolet sterilization. The disinfection targets not only passengers but also personal luggage carried by travelers.

[0036] The walkable disinfection device 1 includes an outer cover 10, a first sterilization section 110, a second sterilization section 120, and a third sterilization section 130.

[0037] The outer cover 10 is provided with an entrance 100 and an exit 140, forming a passageway. Inside, a passageway is formed for passengers to pass through, and multiple sterilization sections are provided to sterilize passengers and luggage during the passage.

[0038] The shape of the outer cover 10 is not limited to the shape shown in the attached figure. It can actually be formed into various shapes, including a cuboid barrel shape. The shape and size of the outer cover 10 can be appropriately determined according to the installation environment, etc.

[0039] The first sterilization unit 110 is located at the entrance 100 of the outer casing 10 and will perform first sterilization on passengers passing through the walk-through disinfection device 1. The first sterilization unit 110 includes a first plasma supply unit 111, a first ultraviolet irradiation unit 112, and a first temperature control unit 113.

[0040] The first plasma supply unit 111 provides low-temperature plasma to the first sterilization unit 110. The first plasma supply unit 111 sterilizes the first sterilization unit 110 using an ion cluster contained within the low-temperature plasma. Furthermore, the first plasma supply unit 111 performs sterilization at a relatively low temperature of below 50 degrees Celsius, enabling sterilization without inconveniencing passengers and also allowing sterilization of products with poor heat resistance.

[0041] Here, the example is shown with the first plasma supply unit 111 installed on the side wall of the first sterilization unit 110. However, this is only one example. The first plasma supply unit 111 can not only be installed on the side wall of the first sterilization unit 110, but its installation position can also be changed in various ways, including the upper wall surface or the entire wall surface of the first sterilization unit 110.

[0042] The first ultraviolet irradiation unit 112 includes a light-emitting diode (LED).

[0043] The first ultraviolet irradiation unit 112 generates short-wave ultraviolet light with strong bactericidal power. By irradiating the first ultraviolet irradiation unit 112 with short-wave ultraviolet light, bacteria, mold, microorganisms, and viruses present in the passengers and the first sterilization unit 110 can be effectively sterilized.

[0044] Here, the first ultraviolet irradiation unit 112 is shown as being disposed on the side wall of the first sterilization unit 110, but this is only one example. In practice, the position and arrangement of the first ultraviolet irradiation unit 112 can be changed in many ways.

[0045] For reference, plasma sterilization is an indirect sterilization method that removes bacteria and viruses by causing charged particles to interact in the air, providing a continuous sterilization effect over large spaces. Furthermore, ultraviolet sterilization is a direct sterilization method that uses short-wave ultraviolet light to act directly, offering a short-term sterilization effect for confined spaces. According to this embodiment, the first sterilization unit 110 can simultaneously perform sterilization by providing plasma and by irradiating ultraviolet light, thereby achieving the optimal sterilization effect.

[0046] The second sterilization unit 120 is located inside the outer cover 10 between the first sterilization unit 110 and the third sterilization unit 130. It will perform a second sterilization on passengers passing through the first sterilization unit 110 by providing air.

[0047] The second sterilization unit 120 may include a blower fan 121, a side fan 122, an intake module 123, and a negative pressure control unit 124.

[0048] A blower fan 121 is located on the upper part of the outer casing 10 and removes dust or pollutants attached to passengers or luggage by spraying air from the upper part to the lower part.

[0049] Side fans 122 are installed on the side wall of the outer casing 10 to spray air toward the passengers.

[0050] The inhalation module 123 is located at the lower part of the outer cover 10 and will exhaust to the outside by drawing in air from the inside of the second sterilization section 120.

[0051] The second sterilization unit 120 removes dust or pollutants adhering to passengers or luggage from the air generated by the exhaust fan 121 and the side fan 122. The air containing dust and pollutants separated from passengers and luggage is drawn into the suction module 123 in a downward direction and discharged to the outside, rather than being diffused to the surrounding area.

[0052] Although not shown, a filter or dust collector for removing dust or pollutants from the intake air may be provided in the intake module 123.

[0053] The second sterilization unit 120 can more effectively remove dust or pollutants adhering to passengers and luggage by spraying air from above and to the sides of the passengers. To this end, the positions of the aforementioned air supply fan 121, side fan 122, and suction module 123 in the second sterilization unit 120 are determined in a manner that can form the most effective airflow, taking into account the internal environment and airflow.

[0054] Furthermore, the second sterilization section 120 can aerodynamically separate the first sterilization section 110 and the third sterilization section 130 by directing the airflow from the blower fan 121 and the side fan 122 downwards.

[0055] The negative pressure control unit 124 can maintain the interior of the second sterilization unit 120 under negative pressure to prevent the air inside the second sterilization unit 120 from flowing into the first sterilization unit 110 and the third sterilization unit 130.

[0056] The negative pressure control unit 124 can prevent the internal air of the second sterilization unit 120 from leaking into the first sterilization unit 110 and the third sterilization unit 130 by maintaining the internal pressure of the second sterilization unit 120 at a level lower than the internal pressure of the first sterilization unit 110 and the third sterilization unit 130.

[0057] The third sterilization unit 130 is located at the exit 140 of the outer cover 10 and will perform a third sterilization on passengers passing through the walk-through epidemic prevention device 1.

[0058] The third sterilization unit 130 may include a second plasma supply unit 131, a second ultraviolet irradiation unit 132, and a second temperature control unit 133.

[0059] The second plasma supply unit 131 can supply high-temperature plasma to the third sterilization unit 130.

[0060] The temperature of the second plasma can be adjusted by the second temperature control unit 133. However, maintaining a temperature higher than that of the first plasma can effectively achieve the desired disinfection effect. The third sterilization unit 130 can achieve a sterilization effect by providing high-temperature plasma and utilizing the instantaneous high temperature of the plasma.

[0061] Here, the second plasma supply unit 131 is shown as being installed on the side wall of the third sterilization unit 130. However, this is only one example. The second plasma supply unit 131 can not only be installed on the side wall of the third sterilization unit 130, but its installation position can also be changed in various ways, including the upper wall surface or the entire wall surface of the third sterilization unit 130.

[0062] The second ultraviolet irradiation unit 132 includes a light-emitting diode.

[0063] The second ultraviolet irradiation unit 132 generates short-wave ultraviolet light with strong bactericidal power. By irradiating the second ultraviolet irradiation unit 132 with short-wave ultraviolet light, bacteria, mold, microorganisms, and viruses present in the passengers and the third sterilization unit 130 can be effectively sterilized.

[0064] Here, the second ultraviolet irradiation unit 132 is shown as being disposed on the side wall of the third sterilization unit 130, but this is only one example. In practice, the position and arrangement of the second ultraviolet irradiation unit 132 can be changed in various ways.

[0065] The third sterilization section 130 can sterilize and remove bacteria, microorganisms, and polluted air present in objects passing through the third sterilization section 130 by means of simultaneous sterilization using high-temperature plasma and ultraviolet light.

[0066] The walk-through epidemic prevention device 1 can be equipped with a thermal imaging camera 20 and a measuring unit 21 at the entrance 100.

[0067] The thermal imaging camera 20 and the measuring unit 21 measure the temperature of passengers before they enter the walk-through quarantine device 1, and can provide the measured results to quarantine officers in real time. For example, the main symptom of the COVID-19 virus, which is currently experiencing a global pandemic, is fever. In this embodiment, by using the thermal imaging camera 20 and the measuring unit 21, suspected infected persons can be separately classified after passing through the walk-through quarantine device 1, thereby preventing the spread of infection. Furthermore, it can prevent suspected infected persons from causing secondary infections after entering or leaving the country.

[0068] According to this embodiment, the walk-through disinfection device 1 can perform multi-level disinfection by using plasma, ultraviolet light, and air jets to allow passengers to pass through the first disinfection section 110 to the third disinfection section 130 during movement. Furthermore, the walk-through disinfection device 1 can perform a first disinfection by providing low-temperature plasma and ultraviolet light irradiation, a second disinfection by air jetting, and a third disinfection by providing high-temperature plasma and ultraviolet light irradiation, thus expecting an effective and powerful disinfection effect. Moreover, disinfection can be carried out quickly and effectively without quarantine waiting time by allowing passengers to walk through. Furthermore, the walk-through disinfection device 1 can detect whether passengers are infected using a thermal imaging camera 20 and a measuring unit 21, thus preventing potential contamination in advance.

[0069] On the other hand, the walk-through epidemic prevention device 1 may be equipped with a control unit (not shown) to control the operation of the first sterilization unit 110, the second sterilization unit 120, and the third sterilization unit 130 by detecting the epidemic prevention status inside the outer cover 10 and the number of passengers. The operation of the walk-through epidemic prevention device 1 can be remotely controlled by the control unit (not shown) according to the number of passengers.

[0070] Furthermore, the outer cover 10 allows for the assembly and disassembly of multiple sterilization units, thus enabling expansion. Connecting portions (not shown) for interconnecting the connected sterilization units can be provided at the junctions of the first sterilization units 110 to the third sterilization units 130. For example, as in the embodiment described above, an assembly of one first sterilization unit 110 to one third sterilization unit 130 can be assembled by adding sterilization units via connecting portions (not shown) located on the outer sides of the first sterilization unit 110 and the third sterilization unit 130. Alternatively, two or more first sterilization units 110 to three sterilization units 130 can be configured for assembly. In addition, the number of first sterilization units 110 to three sterilization units 130 can be appropriately increased or changed as needed.

[0071] Furthermore, the walkable epidemic prevention device 1 may be provided with wheels (not shown) at the bottom so that the outer cover 10 can be moved. For example, by providing wheels (not shown) at the bottom of the outer cover 10, the walkable epidemic prevention device 1 can be moved to the position where it needs to be installed and the installation can be carried out.

[0072] According to this embodiment, since the walk-through epidemic prevention device 1 adopts a walking passage method, epidemic prevention can be implemented quickly and effectively without quarantine waiting time.

[0073] Furthermore, the walk-through epidemic prevention device 1 can implement multi-level sterilization through multiple sterilization units, and the sterilization effect is better than that of the quarantine personnel directly carrying out sterilization. It does not carry out epidemic prevention that is biased towards a specific source of infection, but can carry out epidemic prevention for multiple sources of infection at the same time.

[0074] Furthermore, the thermal imaging camera 20 and the measuring unit 21 can be used to identify suspected patients with infectious diseases in advance before passengers enter the walk-through epidemic prevention device 1, thereby preventing them from entering the epidemic prevention device.

[0075] Furthermore, by forming modular structures that can be assembled, it can have the scalability to add additional structures according to the type of infectious disease.

[0076] Furthermore, due to its ease of installation and dismantling, and its mobility, it can be used in various environments.

[0077] On the other hand, although the above embodiments use the case of installing the walk-through epidemic prevention device 1 in an airport as an example, it can be installed not only in tourist passage facilities, but also in multi-purpose facilities such as shopping malls, supermarkets, exhibition halls and concert venues with large flow of people.

[0078] As described above, several embodiments have been illustrated with reference to the limiting drawings. However, those skilled in the art to which this invention pertains can implement various technical modifications and variations based on the above description. For example, the described techniques can be performed in a different order than the described methods, and / or the described systems, structures, devices, circuits, and other structural elements can be combined or integrated in a different manner than the described methods, or they can be replaced or substituted by other structural elements or equivalent technical solutions, and even so, appropriate results can be achieved.

[0079] Therefore, other instances, other embodiments, and other technical solutions with the same scope of protection as the invention also fall within the scope of the appended invention claims.
